During construction work outside and inside the premises (if they have high ceilings), scaffolding is often needed - it is not necessary to carry out drawings of auxiliary structures with your own hands, but anyone can assemble them using a ready-made method.
Scaffolding is widely used in construction and repair. Even the usual do-it-yourself wall plastering it is not easy to carry out without them, and the installation of a roof or wall siding becomes a very difficult task without auxiliary supporting structures. Of course, the mobility of stepladders or hastily put together goat-stools is higher, and their cost is noticeably lower.
But only solid-sized scaffolding will allow you not to be distracted by the constant movement along the facade or the wall being repaired of everything you need. Saving time and effort, concentrating energy on repairs - the main benefit from scaffolding, homemade or purchased. The productivity of construction labor when using scaffolding increases several times - so that their cost can be entered in the column "payment for the speed and convenience of repair."
Any design of scaffolding must be reliable and durable - including taking into account the people, tools, building and consumables placed on them. If there is even the slightest doubt that scaffolding cannot be assembled with the proper margin of stability, it is better to purchase a finished, branded product in a specialized store. Moreover, the choice of such products is quite diverse.
The term "forests" itself is associated with the historical experience of finishing facades with plaster, stucco and painting during the construction of palaces and other elite buildings. For plasterers and finishers, multi-meter "shelves" were erected from real logs and platforms. After the completion of the work, all this material was spent on firewood, leaving to posterity only its name and the principle of construction.
Modern options are based on a frame and are made taking into account reusable use. Structurally, scaffolding can be performed in the following options:
Suspended, clamp and wedge options are only purchased, their independent "production" is not recommended. Pin or frame scaffolding, the drawings of which are given below, are assembled with their own hands with the appropriate carpentry and metalworking skills.
Wood is the easiest to process and at the same time inexpensive material - the creation of wooden scaffolding fits into several repair stages, which are quite doable on your own. We will describe in detail how to make them from wooden beams, boards and slats.
To work, you will need several types of wood. Bearing supports are made of timber 10x10 cm in size (a smaller section will not allow heavy construction work to be carried out from scaffolding). Horizontal floorings are knocked together from thick boards (from 50 mm), stiffeners - from boards with a thickness of 25 mm or more. Fencing rails with a thickness of 20 mm or more can be used. Wood for supports and platforms should be free of knots and cracks, it should be treated with special compounds to prevent rotting and mold.
The end sides of the wooden scaffolding must be made at a converging angle - this will significantly increase the stability of the structure and will not interfere with the repair of walls.
In addition, it is advisable to choose load-bearing supports from a 10x10 cm beam that are solid, and not composite - then the strength of the multi-storey structure will be higher. The minimum allowable width of homemade wood scaffolding is 50 cm, their length can be 3-4 meters. The height limit is considered to be 6 meters, otherwise the risk of overturning the scaffolding during operation is high. For work, you will need standard woodworking tools - saws and hacksaws, a planer, a drill and a screwdriver.
Two beams with a height of not more than 6 meters are laid on a flat horizontal surface, the distance between them is equal to the planned length of the scaffolding. The other two fit right next to each other. The upper part of the bars should slightly converge upwards for the stability of the entire structure. For a distance between supports of 4 meters along the length of the scaffolding down below convergence of 40-50 cm is enough up. That is, if the center distance between the support beams at the bottom is exactly four meters, then from above it is set at 3.5-3.6 meters. The result is two symmetrical wooden trapeziums.
Sidewalls from a bar are screwed to the support beams with self-tapping screws. They will serve as supports for working decks, so they are mounted from the inside. In general, self-made wooden scaffolding can have no more than three "mounting floors", so there will be only four sidewalls from a bar. Three correspond to the levels of the forests, and the lower one serves for strength, it is fixed 20-30 cm from the ground.
To connect the side trapezoids into solid scaffolding, you will need an assistant (and preferably two). It is difficult to perform this operation alone, and the docking accuracy will certainly suffer. Side crossbars are prepared in advance, and they will be of different lengths. The fact is that sustainable forests should be pyramidal in both width and length. The required angle of convergence is small, otherwise an uncomfortable gap will appear between the upper part of the scaffolding and the facade being repaired. Say, for a width of 1 meter, an upper clearance of 85-90 cm will be enough.
Having installed the wooden sidewalls vertically and slightly tilting them towards each other, we fasten the side crossbars with long self-tapping screws. The use of screws is preferable because after repair and construction work, the scaffolding can be disassembled (partially or completely) and folded in a barn or garage.
It remains to nail boards for flooring and a fence above each platform to the transverse bars. On the sides of the scaffolding, additional crossbars can be filled, which will act as stairs. It is also useful to make a knot in the form of a retractable pin above each support for attaching scaffolding to earthen soil - it is removed on flat surfaces, and the whole structure stands on the cuts of the end beams.
When erecting walls or exterior decoration of buildings, scaffolding is used. This design makes it possible to safely carry out work at height and keep the necessary tools and supplies of materials used at hand.
Despite the fact that scaffolding is presented in many types, their designs contain identical parts that carry the same purpose:
In the manufacture of forests use:
A wood structure is much cheaper than a metal one, but it can only be used with two or three assemblies. In the future, it is suitable only for "ejection".
Scaffolding made of metal pipes, although much more expensive than wooden ones, is not limited in use. They are easy to dismantle and carry as needed. In addition, pipe scaffolding can be increased in height, complementing the tiers.
To make scaffolding from wood and pallets with your own hands, it is necessary, first of all, to develop drawings and determine the dimensions.
There is no need to invent anything in this regard. Many years of practice has itself determined and established sizes that are convenient for work:
DIY step-by-step scaffolding:
If you need to install two or more sections, then they are connected to each other with a wide board, which is stuffed onto adjacent supports. To prevent splitting from nails, you must first drill holes for them.
When starting to make collapsible scaffolding from pipes with your own hands, you need to know that in terms of their design data they are identical with wooden scaffolding. The difference among them is the adapters that are used to increase the height of the structure.
To assemble one section, you will need:
To assemble the structure, you must follow the instructions: how to properly make scaffolding.
The assembly of scaffolding from pipes includes the following operations:
A photo of how to make scaffolding can be seen below.
It is important to remember that the diagonal crossbars must be fixed on one side of the structure, and the horizontal ones on the opposite side. Then when assembling, they will not interfere with each other.
Note!
Note!
All high-altitude work is characterized by increased complexity, and in this case it is definitely impossible to do without special devices. One of them is scaffolding. Their price is calculated in rubles / m², and even in relation to the cheapest set (frame) is about 140 - 145. Besides, where to put it then? Rent can also be expensive (from 55) if the repair or construction drags on for a long time, which usually happens in practice.
Plus - some problems with the transportation of forests, since personal transport is not suitable for these purposes. In the field of low-rise buildings (for the private sector), the best solution is to make them yourself.
There are opinions that it is better (and cheaper) to rent metal and wood scaffolding than to assemble it yourself. The main argument is that buying pipes will cost more. And such judgments are supported by economic calculations. Apparently, the authors of such comments live in city apartments and have a rather vague idea of what it is like to maintain their home in proper condition (both the front part and the premises, the height of which, as a rule, exceeds the typical one). But the owner has to do this regularly.
Moreover, the combination of materials such as metal (skeleton) and boards (flooring at each level) is considered optimal. One of the advantages of wooden scaffolding is (the second is the low final cost) that the structure is easily disassembled after construction (repair) is completed, and the material is used for other economic purposes. But there is also a significant disadvantage - the limitation in carrying capacity.
That is, on such a device, only such work as facade design (painting, siding), ceiling treatment, plastering and a number of others can be carried out. When erecting brickwork or at the same time staying at a height of several people, wooden scaffolding is unsuitable. But the assembly of pipes and boards is universal in use.
The only difficulty is in the correct choice of the scaffolding option and the method of fastening all structural elements. The cost of manufacturing such multi-level scaffolds is justified only if they can be disassembled and stored in a barn (on site or elsewhere) until the next use. But spending money on a non-separable model, welded, is irrational, and it is unlikely that anyone will do this. It is impossible not to take into account such factors as the complexity of manufacturing, the strength of the structure and its stability.
Clamp. Plus - the ability to change the geometry of the skeleton along any of the axes. Minus - the complexity of the installation / dismantling of the structure. In addition, if necessary, to increase the bearing capacity, you will have to buy fasteners. Only one wire, especially a rope, in this case is not enough.
Wedge. Differ from all similar models in application in the increased reliability and durability. But the manufacturing costs are immeasurably higher (primarily for holders). For the private sector - not the best option.
Pin. Plus - low weight with the ability to withstand a significant load; ease of assembly (albeit relative). Minus - high cost; increased pressure on the soil. A number of additional measures need to be taken to ensure sustainability. As a rule, such forests are not used in the private sector. The main reason is the complexity of manufacturing. Here you need accurate calculations and a welding machine.
Frame. Plus - the weight of the structure is small, but with proper drawing up and assembly, such scaffolding is able to "carry" a load of up to 200 kg / m². The height restriction of 50 m for a private building does not matter much. It is this model in the field of individual development that is considered the best.
It is pointless to designate the exact linear values of structural elements - they simply cannot be. The dimensions of scaffolding are selected based on the specifics of the work being carried out, the availability of space for their installation, the number of craftsmen who are simultaneously at the height, and a number of other parameters.
All numerical values are in mm.
By material:
By section:
To ensure sufficient strength of scaffolding flooring - not lower than "magpie".
Those home craftsmen who are not satisfied with the given dimensions for some reason can take the following drawings as a basis.
Preparing details. Pipes are cut first. Even if a drawing has been drawn up, there is no need to rush with the boards. After assembling the skeleton of scaffolding, their dimensions will still have to be specified. This will save you from unnecessary work if you need to fit pre-prepared flooring elements in place. The ends of round pipes (about 80) are flattened so that you can then drill holes for fasteners. To facilitate such a “pressing”, it is worth making an axial cut (metal cut) to the specified length.
To ensure maximum stability of scaffolding, it is necessary:
If you carefully understand the manufacturing process, it turns out that there is nothing complicated in assembling scaffolding. The main thing is the correct calculation and accuracy.
It is difficult to imagine a construction site without scaffolding. With them, walls are erected and finished, roofs are made, gutters are installed, etc. In each case, they must be strong and reliable. If renting factory-made scaffolding is expensive, make scaffolding from a profile pipe with your own hands. This is often done in individual construction, where the height of houses rarely exceeds two floors. How to assemble these simple designs, this article will tell
Construction scaffolds are made entirely of wood or metal pipes combined with boards.
On a note! Homemade scaffolding should not be subjected to heavy loads. No more than 2 people are allowed on them at the same time.
For the construction of frame scaffolding, steel racks and frames will be required. The flooring in them is made of wooden boards. Aluminum structures are lighter and can withstand less stress. For one section, the following dimensions are recommended:
The number of sections determines the height of the building and the perimeter of the outer walls of the house.
A simple option for homemade scaffolding
Before proceeding with the assembly of frame scaffolding, the following materials should be purchased:
Note! In the course of work, you will have to use a hacksaw or grinder, a drill with a drill for metal, a welding machine. Connections can also be made with special threaded fasteners.
Before starting the assembly of scaffolding, the ground should be carefully compacted in the area where they are placed. When carrying out work in the rainy season, it is desirable to make a drainage system. So the soil under the scaffolds will not be washed away, and the structure will remain initially strong and reliable. For the stability of the structure, boards are placed under the support posts.
Wooden frames are designed for light weight
Important! Even a small play at the joints or incompletely screwed threads can cause the scaffold to tilt or collapse, and this poses a danger to people's lives.
Homemade scaffolding from a profile pipe is assembled in the following sequence.
On a note! Temporary structures from several sections are connected by adapters. To do this, cut off 8-10 cm pipes with a section of 3x3 cm, thread a section of the profile with a section of 2.5x2.5 cm into it. The parts are connected by welding.
Some people are concerned about the question of whether it is advisable to make scaffolding on their own. The following arguments are presented as an argument against them.
After completion of the work, the wooden scaffolding is dismantled, but this takes a lot of time. Boards, if they are not urgently needed, will also have to be folded somewhere. It should be borne in mind that wood scaffolding is knocked down with nails, and not assembled using self-tapping screws. Boards after such disassembly will not remain intact, moreover, they are often stained with mortar or paint.
Temporary structures of their pipes can be rented out
Note! Do-it-yourself metal scaffolding can be rented out.
Homemade scaffolding from a profile pipe is a matter of personal choice. They help at different stages of construction and after completion of construction can be rented out. So you pay for your labor and materials.
In construction or repair work carried out at height, scaffolding is indispensable. Construction fixtures can be rented for the duration of the job, but it's not cheap, especially on long-term renovation projects. Having calculated the required height and configuration, scaffolding can be designed independently.
The purpose of scaffolding is the possibility of delivering building materials to the height and the safety of builders staying there during work. To do this, the design must be stable, durable, with a lifting, lowering and protection mechanism. Wood or metal is best for building scaffolding.
Scaffolding consists of several elements:
