How to install a double interior door. Ready from the store

Installation of interior double doors has a number of features. First of all, this concerns the availability of special tools, and secondly, technological features.

First you need to get acquainted with their division into types. It occurs according to the following parameters:

• on general principle: can be hinged and sliding;
• production material: aluminum, glass, plastic, MDF or wood;
• by design: paneled, paneled glazed, deaf, massive.

Initially, you need to properly dismantle old door. This applies primarily to the box and platbands. Dismantling is carried out using: an ax, a hammer and a pry bar.

It is important to remember that if old box must be kept intact, the procedure should be as follows:

• removal of platbands;
• cleaning from cement and foam;
• removal of self-tapping screws, in the case when the beam was fixed with nails, they can also be carefully cut off with a grinder.

After removing the box, the remnants of leveling materials are removed from the doorway using a perforator. When the plaster is laid qualitatively, it has smooth surface, it can be left only by cleaning off the remnants of the mounting foam.

The next step in the installation is to take measurements. First you need to consider what kind of structure will be installed: sliding or swinging. After all, each of them has a number of opening features.

Sliding doors are well suited and fit into rooms with a small area. After all, due to them, space is significantly saved. To install them, you will need to purchase a special design, necessary work hinged doors.

Note: you can build a plasterboard box, where the doors will subsequently “go in” after opening. However, it will significantly reduce the space of the room that could be used for furniture.

The swing method of opening door panels is very popular. After all, it increases the level of sound insulation, unlike a sliding door. However, swing doors occupy more space in the room and they need more free space for maneuvers. This type of door is most often installed in large rooms.

After the design of future doors is selected, you can proceed to measuring the existing opening. To subsequently decide whether it requires changes (reduction or increase). It is worth remembering here that the width of the box should be 110 mm less than the opening.

Under this type of door, the opening should already be wider than both leafs and another plus 100mm.

Assembly and installation of the door frame

Before proceeding with the collection of the box itself, it is required to verify the conformity of the timber, and if discrepancies are identified, adjust it to the required dimensions. Next, the procedure is as follows:

It is worth remembering: so that in the process of screwing in self-tapping screws, wooden elements remained intact, without cracks, immediately before this, drill a hole. Accordingly, if the diameter of the self-tapping screw is -3.5 mm, then the drill should have - 2.5 mm.

Box installation

Because how accurately the installation of the box was carried out, it actually depends most of performance and subsequent right job the double door itself. This will require the use of a level with three eyes and wooden wedges.

Sequence of actions:

1. The assembled box must be placed in the opening. Use a level to level the structure. Here you will need to monitor not only the coincidence of the vertical lines, but also then, no matter what the edges of the box go beyond the opening itself.
2. After setting the box in all respects, it must be fixed. This is where wooden wedges come in handy.
3. Drilling holes for self-tapping screws in the box. In parallel, it is necessary to make marks on the wall.
4. Drilling holes in the wall according to the marks. To do this, you need to pull the box out of the opening.
5. Putting traffic jams and fixing the box in the opening.
6. Foaming of the remaining cracks.

Only after all this, the door is hung, the locks are inserted and the frame is framed.

Here everything goes much faster and easier:

1. The rollers are screwed to the door leafs.
2. Marking the height of the guides for the rollers.
3. Outlining, with the help of a level, lines. Fixing a bar on it (its thickness should be from 40 to 50 mm). He is screwed to the wall.
4. Installation of guides on the bar.
5. Door hanging.

Now you see that in the installation of interior double doors any type, nothing is difficult.

Often after overhaul in the house, new interior requires the installation of double doors, and then the question arises, how to install an interior double door?

Installation of double interior doors is not particularly difficult, although it requires certain carpentry skills. For this work, you can invite a specialist or try to cope with this task yourself. Below in the article, it is described in detail how to install double doors, and what tools and materials you will need for this.

Materials and tools

• protective glasses;
• a hammer;
• hacksaw;
• level;
• finisher;
• pencil;
• stationery knife;
• double swing door with frame;
• roulette;
• finishing nails (38 mm);
• finishing nails (76 mm);
• wooden wedges.

Double door installation

Measure the doorway to make sure you have enough space to install the new double door frame. The space for the box should be 2.5 cm wider and 1.5 cm higher than the dimensions of the box. You should also make sure that the jamb of the box new door It has right size and corresponds to the width of the wall partition.

Install the door frame in the opening in the wall. First, the lower part, then give a vertical position, gradually tilting forward. Make sure the jambs are flush with the wall.

Using a level, make sure the top of the box is level. After the first stage of installation is completed, fix the box in doorway using finishing nails (38 mm). Nails should be driven at a distance of 150 cm from each other along the entire ceiling of the box.

Attach to door frame level. Using a hammer, drive wedges into the gap between the wall and the frame jamb until the jamb is level. After you have aligned the position of one side door frame ki, secure the box by driving nails (76 mm) through the frame jamb, wooden wedges and partially into the wall stud. Hammer nails in the center of the jamb and in place of future canopies. Repeat the same procedure for the second joint.

Install the doors and make sure they close, open, level and have a 0.3 cm gap between the edge of the door and the jamb. If not, then you will have to remove the door, pull out the nails and adjust the position of the box. After everything is fixed, re-hammer the nails into the box.

The next step is to drive wedges under the base of each box jamb. Saw off the protruding pieces of the wedges so that they are flush with the wall.

Installing a double door is the same as installing ordinary door requires preliminary alignment boxes and doors before firmly fixing and attaching it to the wall. If the box and door are installed incorrectly, it can get to the point that you have to literally break the box out of the wall, with no hope of its further use.

A properly installed interior door is always a matter of pride, especially when the installation is done by hand. If you still do not know how to quickly and correctly install the door, then nothing prevents you from doing this.

With good doors and living well

Agree that any apartment is unthinkable without entrance and interior doors. Interior doors successfully combine and perform practical and aesthetic functions, limiting adjacent rooms in the apartment.

Being the "first" object of interior design, interior doors, both single and double doors, give a stylish and complete look to the room. How to choose and install an interior double door correctly?

The design of interior double doors

Let's start with the fact that double-leaf interior doors are somewhat different from single leaf doors, namely the width of the opening. For double-leaf doors, the width of the opening ranges from 1300 to 1900 mm.
Double-leaf swing doors consist of two door leafs united by a common door frame. Along the perimeter of the common block door frame doors are framed with platbands.

No matter how diligently the interior double doors are installed, a gap of several millimeters is formed between the canvases. From the outside of the interior double-leaf doors, the gap is covered with decorative slats. In some cases, one of the wings of double-leaf doors, as necessary, is fixed with a door latch (end bolt).

Material for the manufacture of interior double-leaf doors

The main (basic) materials in the manufacture of interior doors are:
plastic
melamine
wood
metal
veneer
MDF panels.

However, the traditional materials used in the manufacture of interior doors are gradually giving way to more practical and inexpensive materials, such as melamine.
When choosing the material for the manufacture of interior doors, it is necessary to take into account the maximum load and functions of the doors, and, of course, the aesthetic component in the overall interior of the apartment.

Door Sizing Method

The method for choosing the size of an interior door for subsequent installation takes into account certain technical features installation. Therefore, before installing a double-leaf interior door, it does not hurt to make additional calculations.

Initially, the height and width of the doorway are measured, taking into account the existing curvature. The data obtained will help to correctly install the door with your own hands. Here are the selection features:
when installing double-leaf interior doors, it is necessary to leave a technological gap between the door frame and the base of the opening. The gap should be about 15 mm wide around the door frame, excluding the floor.
to exclude possible jamming during humidity changes, it is also necessary to provide a gap between the door leaf and the frame of about 5 mm.
Of course, when choosing a double-leaf interior door, it is necessary to take into account the possibility finishing works on the floor plane near the door.

Door installation technology

Being in the zone of constant visibility and enhanced operation, the quality of installation of double-leaf interior doors is of particular importance. Thanks to the numerous offers of manufacturers of interior doors and simplified versions of models, their self-installation is allowed.

However, the procedure for installing and installing an interior double-leaf door with your own hands requires phased implementation technological operations. Moreover, the doors are double-leaf interior doors, the dimensions of which may differ from the prepared standard doorways in the apartment, will require additional installation efforts.

Stages of installation of an interior double door

Do-it-yourself installation of a double-leaf door consists of the following steps:
dismantling, if necessary, the old leaf and door frame
manual assembly of the door frame from the manufacturer
door frame installation
installation of canopies
installation of the crossbar on the sash
hanging door leaves
installation and fixation of cashers
checking the operation of the door.

Dismantling the old door leaf begins with removing it from the hinges. Then the door frame is dismantled, followed by the removal of fasteners and insulating materials. After cleaning the door frame, you can proceed to the manual assembly of the door frame. The delivery set of the door includes assembly instructions. Take full advantage of it.

The assembly technology provides for such operations as sawing and arranging elements, as well as the installation of canopies. The process of opening and closing the two wings will depend on the quality of the installation of the canopies. Therefore, the first thing that needs to be done is to make the optimal installation of loop cards and bolts, if necessary.

Installing the door frame in place begins with its location using a plumb line or level. Fixation correct location boxes are carried out using anchor bolts and dowels. Due to the small mass of the interior door, preference can be given to dowels and self-tapping screws. The box is fixed at 6 points: at 3 points on the hinge side of one leaf and 3 points on the second leaf.

For this, mounting holes are drilled in the elements of the box. It is recommended to install wooden blocks between the elements of the box and the doorway. For foaming the resulting voids during the installation of the box, mounting foam is used, which has a slight expansion coefficient during solidification.
When installing canopies, the locations on the sashes are initially determined and marked. These are the extreme upper and lower points on the sashes at a distance of 150 mm.

Having carried out the installation and adjustment of the canopies, they are fastened with screws 35 mm long. Reciprocal elements of canopies on an installation box fasten the same way. Installed canopies must guarantee a technological gap between the door leaves and the box. Having installed a double-leaf interior door on your own, it is necessary to perform a performance check in order to exclude overlays.

After installation door leaves platbands are installed and fixed around the perimeter of the entire door frame.
More detailed information on how to install a double-leaf interior door is presented in the video.

Until recently, installing interior doors with your own hands was a rather difficult task and required serious experience and skills from a person. Now everything has become much easier, having a good tool and knowing the procedure for installing interior doors, any House master able to finish the job in a day. Next, we will step by step analyze how to properly install an interior door in two ways.

Variants of canvases for interior doors.

Before you put an interior door, you must first select it. When choosing, there are 2 main criteria - this is the size of the structure and the material from which the doors and the box to them are actually made.

Material selection

Not so important is the installation of an interior door in wooden house or in a room of an urban high-rise building, the design must be not only beautiful, but also reliable, and this primarily depends on the material.

Fiberboard is perhaps the most common option. The design is a hollow box on both sides closed with thin fiberboard sheets and based on a frame made of wooden blocks.

You should not hurry with the installation of such a door, of course it is light and cheap, and it can look quite decent, but not everything is in order with reliability, such a design can be broken even with a fist, plus there is a high probability that in a couple of years it will begin to exfoliate.

MDF is golden mean between cheap fiberboard and good wooden structure. The array is dense, durable, and most importantly completely environmentally friendly. Self-assembly interior laminated MDF sheets at home is a great way out if there are no funds for installers, and beautiful door I want to.

The MDF canvas must be laminated with high quality, then it will not visually differ from the wooden one.

Natural wood - traditionally it is believed that the installation of wooden doors is the most the best option, but this is wrong, here you need to look at the quality and the manufacturer. Believe me, sometimes it is better to insert interior doors from good MDF laminate than to take a raw pine, which in six months will lead.

At the time of buying wooden canvases the quality of the forest must be carefully assessed.

If you decide to change interior doors and you have a high-quality wooden loot, then it is not necessary to touch it, you can only replace the canvas. In this case, the technology for installing interior doors will be much easier.

GOSTs, tolerances and unclear questions

The size of the doorway for installation is perhaps the most important of the initial parameters. To this day, all such structures are made according to Soviet GOSTs, by the way, the Chinese are also guided by these dimensions, but in Europe, despite the supposedly uniform standard, many countries do it their own way.

So if our minimum web width starts from 600 mm and further in increments of 100 mm, it reaches 900 mm, then France produces canvases starting from 690 mm, but the graduation also comes in increments of 100 mm.

Germany, Spain and Italy, as well as all the countries of the former socialist camp, in this respect are guided by almost the same standards as our manufacturers.

Interior doors have clear standards that you need to check before installing an interior door yourself.

As for tolerances, a gap of 3 mm is left between the box and the canvas itself on the sides and top. According to the rules, at least 20 mm must be made between the floor and the canvas. This slot is needed for normal ventilation in the apartment.

Any gap can be left along the perimeter of the box in block buildings, up to several millimeters, the main thing is that the box becomes even, but if we cut the doors in a wooden house with our own hands, then we set a tolerance of at least 15 mm, it is needed in case the house gives shrinkage.

When an interior door is selected, installation is already the last stage, before that you need to read the description in detail, because the price can be indicated depending on the configuration, there are 3 options:

1. Only the door leaf is for sale - this option is good if the door is planned to be installed on an old box;
2. The canvas is sold together with the box, but the box comes unassembled, here, even before you install the interior door with your own hands, you will have to cut it to size and assemble the box, which in most cases is even good;
3. Fully assembled units with a finished frame, canvas, locks and hinges are installed only if preparation of the opening is not required. There it is enough to cut the racks in height and install the interior door yourself.

Do not forget that it is not enough just to install interior doors in the opening, complete installation The interior door provides for the arrangement of platbands, extensions (if necessary) and fittings, so it is also advisable to take them immediately, otherwise the shade may not come up later.

Installation of interior doors will not be complete without platbands and fittings.

There is another important question - when to install interior doors during repairs? So, the instructions for installing interior doors say that such structures are mounted at the very end of the repair, after finishing the walls, floor and ceiling, but before installing floor skirting boards.

Two mounting options

With dimensional tolerances and other acute issues sorted out, now it's time to find out how to install the interior door yourself. But in order to assemble and install the structure, we need a tool.

A few words about the instrument and related material

To install interior doors, we need:

• A hacksaw for wood, but ideally it is better to have a miter saw, it does not leave chips, plus you can set the exact cutting angle there;
• To expose openings between the box and the wall, wedges are required;
• A hammer;
• Chisel;
• Screwdriver;
• Electric drill;
• Plumb;
• Level;
• Pencil;
• Roulette.

Install interior doors yourself good tool unreal.

Important! Safety regulations categorically prohibit cutting a tree with a grinder. If you value your health, don't even think about it.

From auxiliary materials to install doors you will need:

• Mounting foam;
• masking tape;
• self-tapping screws different size and sections;
• Anchor bolts with dowels.

Opening preparation

Ideally, before installing an interior door, the edges of the walls should be, if not plastered, then at least leveled with a cement-sand mortar.

But in real conditions, the preparation of the doorway for the installation of an interior door ends with fitting the dimensions to the box, because then the impartial cracks will foam up and close with platbands, so there is no point in inducing special beauty.

It is advisable to level the doorway before installing the box.

There is one here important point: often the installation of a double interior door requires an expansion of the opening, and so, when it comes to piers, they can be “redrawn” as you see fit. But if the wall is load-bearing, then a slight expansion of no more than 5-7 cm is allowed, otherwise there may be problems, both with the wall and with the law.

Box assembly

A box for a door with your own hands can be assembled in two ways - this is with cutting the corners of the upper bar at 45º and joining the bars at a right angle. Both methods are good, but it is believed that the 45º corner joint will look more elegant.

Really high-quality corner trimming can only be done with trimming, if you are assured that for this the usual one will do a plastic miter box and a hacksaw for wood, do not believe it, so you can ruin the boxes.

The vertical posts are cut off at 45º first, after which you can proceed to trimming the upper horizontal bar. In order to set aside 3 mm, it is convenient to use a piece of fiberboard as a template.

We measure the gap relative to the upper bar with a template.

• You put the top bar cut on one side and slide it along the cut of the template;
• Next go to opposite side doors and applying the same template, mark the cut line.

Trimming the top bar at an angle using trimming.

Now we lay out the finished, trimmed slats of the box on the floor and once again control the dimensions.

It looks like a door frame cut at an angle.

• The box is fastened in stages. First you need to tightly connect the planks to each other the way they should be;
• The slats of the box when screwing the screws can crack, so that this does not happen, before assembling, we need to drill channels for the screws. This is done with a 2.5 mm drill (we have a 3.5 mm self-tapping screw);

Preparing to fasten the box.

• Now you can screw the screws into the ends of the box on both sides, and there should be 2 screws on each side of the corner.

There is a small nuance here, the vertical bar of the box to which the hinges will be attached completely on both sides does not need to be tightened, we still have to remove it.

Fixing the box with cutting at an angle.

If there is no miter saw in your arsenal, then it is better to mount the box strips at a right angle. Perhaps this is not so aesthetically pleasing, but the step-by-step instructions will be somewhat simpler.

We start by trying on the upper crossbar, we will cut it between the two side posts. Some masters mount the crossbar above the side racks, there is not much difference, here it’s already convenient for anyone.

Along the perimeter of the box, we have a side into which the door leaf lies when closing. To embed the upper cross member, on the side racks we need to remove this side. To do this, we apply the upper cross member to the rack, mark and cut the side with a hacksaw, and clean out the place for installation.

Now we just have to insert the top bar between the two side posts, drill holes for a pair of self-tapping screws and secure the inserted bar with self-tapping screws.

If you decide to put the bar on top of the racks, then there you will need to cut the inner side on the top bar, then drill and drive the screws from above, as shown in the diagram below.

Do-it-yourself installation of a bar placed on top.

Installing hinges and handles

For a door, installing hinges is one of the most milestones. In principle, you can embed a lock and hang hinges even after installing the box in the opening, but if you mount the doors yourself (without assistants), then it is better to do it right away.

Loops are overhead and hidden. Butterfly overlay hinges are easier to work with, since you don’t need to cut anything in the door leaf and frame, so we’ll start with them.

A little advice: if the door should open on the right side, then you insert the hinges on the right, respectively, for left-hand opening, the hinges must be mounted on the left rack.

Installation of loops begins with markings on the canvas itself. According to the rules, the distance from the top or bottom point of the canvas to the loop should be 200 - 250 mm. You can measure with a tape measure, as in the photo below, but if there was no tape measure at hand, then use the loops themselves, there standard size equal to 100 mm.

We make markings for the installation of loops.

Do not confuse: the small (inner) part of the butterfly loop is attached to the door leaf, and the large one, to the box post. Before screwing the screws under them, you need to drill holes, only after that the screws are driven.

All hinges have recesses for the heads of the screws, so make sure that these recesses “look” up. If the hinges are installed the other way around, then the heads of the self-tapping screws will remain above the hinges, respectively, the doors will not close completely.

We drill holes for butterfly loops.

The box is practically assembled, now we put it on the floor and put the door leaf inside. As you remember, we should have 3 mm around the perimeter of the canvas, so we immediately insert as many homemade fiberboard templates as possible (3 mm thick) between the box and the canvas.

One part of the loop is screwed to the canvas, in order to screw the second part of the loop to the box, we make a mark on the box. Then we unscrew the self-tapping screws fixing the bearing vertical bar and fasten the reciprocal part of the loops to it. Then we return the bar of the box to its place and fix it completely.

Attach loops to vertical rack boxes.

Self-installation of hidden loops is not much more complicated than the above method. The difference lies in the fact that in the door leaf and the box you need to cut grooves for the hinges. This is done with a mallet, chisel and knife.

We cut grooves for mounting hidden loops

As for the installation door handle, then you can read about this in detail, as well as view it on the video in this article. And do not forget that the hinges must be lubricated, you can find out about the rules for lubrication.

There are different ways to install interior doors in a wall opening, it all depends on the specific conditions. Next, we will consider the simplest and most popular options.

Method number 1. Classic

On the this moment in our case, the racks of the box must be cut to the height of the opening, the hinges and the lock are embedded, the door is closed, and 3 mm thick templates are inserted between the canvas and the box.

When the door block is inserted into the opening, first of all, wooden or plastic wedges are driven around the perimeter, they will hold the block until it is finally fixed.

The classic scheme for installing interior doors using wedges.

Fixing is a rather crucial moment, here we expose the block vertically and horizontally. Keep in mind: the wall is not always strictly vertical, so check the box with a plumb line.

It is better to check the vertical by plumb.

In order for the door block not to fall out from a strong push, it must be firmly fixed with anchor bolts or at least long self-tapping screws. We recommend using anchor bolts with a thickness of 6 - 8 mm.

The principle is simple:

• Drill a through hole in the box and slightly drill into the wall;
• Remove the door block and drill holes for dowels at the drilling points;
• Put the box in place and fix it with anchors. The box should become clear in level, since before that we have already verified everything.

If you fix the box with long self-tapping screws, then they are installed around the entire perimeter with an interval of half a meter, but the screw caps need to be somehow hidden. You can close them with a decorative strip or plastic lining.

Anchor bolts are a powerful thing and 3 points are enough to fix the box - two points under the hinges and one under the lock plate. In combination with mounting foam It's enough.

Now we fill the perimeter of the box with mounting foam. We move from the bottom up, the foam must be blown out without fanaticism, because when it expands, it can squeeze out the door frame.

Plus, at the time the foam is blown in, the door block must be assembled and three-millimeter templates must be inserted around the perimeter, this will protect the box from deformation.

Remember: only on the "bare" foam (without screws or anchors) the door block cannot be fixed.

Method number 2. Metal hangers

If mounting the box on self-tapping screws or anchors is not suitable for you, the same can be done using metal hangers. These hangers are used for mounting frames under drywall.

Use of hangers to fix the door frame.

The technology is similar:

1. Collect the box;
2. Insert the box into the opening and level it;
3. Fix the box with wedges in the opening;

1. Bend the wings of the hangers along the wall;
2. Mark the entry points for dowel-nails and drill holes for them;
3. Attach the wings of the suspensions to the walls with dowel-nails;
4. Fill with foam and wait until it hardens.

The size of the box for double-leaf interior doors is twice as large, respectively, the probability of squeezing out the racks and the crossbar with mounting foam is higher, so installation on suspensions is optimal here.

Fixing the frame for double doors on suspensions.

Conclusion

Both of the above methods have been tested in practice and work perfectly. For the same craftsmen who wish to install interior sliding doors, we have prepared step by step instructions.

Installing interior doors with your own hands is not as difficult as it seems.

The double version of interior doors is usually used in two cases - a large doorway and small room. Compared to one canvas, they take up much less space in open form. There is another reason for this choice - double-leaf interior doors look very elegant, especially modern models products. Their canvases can be hinged and sliding. There are also swing models, but they are used extremely rarely. How to install a bi-fold interior door? Installation of double-leaf products is not difficult, but it requires a certain sequence and knowledge.

Opening preparation

Before proceeding with the installation of the door, an opening for it is prepared. If there is a need to dismantle the old door frame, then this is done using a nail puller, a hammer and a screwdriver. Then the opening is cleared of the remnants of plaster and foam. Depending on the material of the wall, a grinder, a chainsaw or a puncher are used to expand it. Reduce space to required dimensions You can use lumber or plaster.

The walls should be ready for finishing and aligned as much as possible - the door frame should not be adjusted to their curvature and knocked out of the plane.

Doorway calculation

There are doors with double-leaf interior dimensions which do not fit into the existing opening. The calculation of its width is carried out according to a simple scheme - plus the width of one canvas, the gap between it and the beam and the thickness of the box. The amount received is multiplied by 2 and 4-5 mm are added to it for mortgages. For example, let's take the most common door width of 600 mm and a frame thickness of 25 mm. (600+3+25)x2+4=1260 mm. Its height is calculated in the same way. But here you should take into account the gap between the door and the floor - 10-20 mm. 2000+10+25+15 (gap between frame and door)=2050 mm. When constructing the threshold, the height of the door, the double thickness of the box and the gap between it and the canvas, multiplied by two, are summed up.

Assembling the door frame

Assembling the finished box

Modern door models are available complete with fasteners and box parts, ready for assembly. In this case, the work will not require much effort. It is necessary to determine the side of the opening of the canvas, measure the length of the racks, taking into account the unevenness of the floor and the prepared opening. In accordance with its height, saw off the bottom of the racks. Then install the dowels in the holes located in the end cuts on the side posts of the box. Pull the parts together until they fit completely and fix them with angle brackets. For this, special grooves are located on the back of the box.

Door blocks can be sold fully prepared for installation, with mounting grooves for hinges, or they can be without them. In this case, it will be necessary to perform a series of actions to cut them - this process will be discussed below.

Do-it-yourself box installation

When assembling a door frame with your own hands, first of all, you need to adjust the timber to the dimensions of the canvas. Its dimensions are double the width of the canvas plus 6 mm for gaps. When calculating the height of the frame, 10 mm is added to the dimensions of the door for clearance from below and 3 mm from above. The upper beam and the ends of the racks adjacent to it are cut at an angle of 45º.

Next, the door frame is assembled - its corners are fastened with three self-tapping screws, the length of which should reach the center of the second beam. Two of them are screwed in at an angle from the side rack up, the third is located between them, but is screwed in from above.

Hinge installation

The location of the fastening and rotary devices is marked on the doors. To do this, 20 cm is measured at the end of the canvas and a loop is applied. Its contour is outlined with a pencil or a sharp knife, and at this point a groove is selected to the required depth. It can be done with a chisel, but in order to make the recess neat, it is better to use a milling cutter - it will allow you to work more accurately and quickly.

Places for self-tapping screws are marked with an awl through the hinge plate attached to the grooves and guide holes are drilled for them. Their diameter should be 1-1.5 mm smaller than the corresponding screw sizes. In the same way, a recess for the crossbar is made on one of the wings.

Then the doors are superimposed on the box, a place for the hinges is marked on the side bars and a groove is made for them in the same way as on the canvases. There are modern fastening-turning devices that do not require such work. But butterfly hinges are not very popular among the masters of the “door business” - there are too many complaints and they prefer time-tested mechanisms.

Hinges are installed on both door leaves and racks, and a crossbar is installed on one of the canvases.

Installing a box in a doorway

When installing the assembled door frame in the opening, using a level and a plumb line, the accuracy of its location horizontally and vertically is checked.

The structure is attached to the wall with long screws (8-10 cm). First of all, the side racks are fixed. Wooden spacers can be installed between them and the wall.

The resulting space around the perimeter of the box is filled with mounting foam. The degree of its expansion should be taken into account - one to five. Details door block must be protected from foam. After it dries, the excess is carefully removed with a knife and the gap is closed with a platband. Door leaf is hung in place and a hole is drilled for the locking plate of the crossbar at a slight angle.

Installation of sliding interior doors

Mounting guides

Doors interior sliding double-leaf photos of which can be found on the Internet - a good alternative to swing models. They free up space, which is very important with a small area of ​​\u200b\u200bthe apartment.

In the case when it is planned to install double-leaf interior doors with your own hands, you should pay attention to Special attention on the material of their manufacture. If for wooden door one guide is enough, then a heavy glass product will require the installation of two structures. Moreover, it is better to plan the lower one in advance so that it is possible to deepen it into the floor. In any case, it is attached to finishing sex, to his concrete base. The horizontality of the guide is checked by a level.

In order to determine the location of the upper guide, which is attached first, the door leans against the opening and a horizontal line is drawn along its upper edge. In this case, it should be borne in mind that a gap of 10-15 mm should remain between the floor and the canvas. You can immediately put a gasket of the desired thickness under the door.

The wooden block on which the guide will be attached must be located strictly horizontally, otherwise the doors will either not open or will spontaneously move to the side. It is fastened with dowels or self-tapping screws - depending on the material of the wall. In addition, there are models with a guide that is mounted on special brackets or to the ceiling.

Stepping back from the wall 2-3 mm, a guide is installed on the lower edge of the timber with the help of screws. It is exhibited strictly according to the level.

The next step consists of attaching the roller mechanisms to the door. On the upper end of the canvas, 20-50 mm are measured from both sides, and the brackets are screwed with screws. If a lower guide is installed, then a groove with a depth of 18 mm is made in the lower part of the doors. Its width should be 2 mm larger than that of the lower rail, made in the form of a flag or knife. Since it is not easy to carry out this process at home, it is better to choose a lower guide, consisting of a U-shaped profile or two rails.

Canvas hanging

Rollers with supporting screws are inserted into the upper guide. Limiters are installed at its ends. The canvas is installed on the flag of the lower rail and hung with brackets on the screws. The fixing nuts are slightly tightened. By turning the screws on the brackets, the door is adjusted vertically, taking into account the clearance above the floor. The second door is hung in the same way. Then with the help wrench the nut is finally tightened, and the blades are blocked on the rollers.

The final stage of installation sliding doors is the installation of fittings and a decorative strip that masks the guide rail.
