Scaffold construction - choose our model
When practical work begins, even for finishing the ceiling in the usual "small-scale", auxiliary scaffolding and scaffolding are necessary. In the course are stepladders, stools, tables. For work such "equipment" is quite inconvenient. Somehow, the understanding of the necessity and importance of how to make scaffolds quickly and reliably emerges by itself.
They are made of different materials, but most often the construction of scaffolding can be wooden, metal or combined of metal and wood. And since forests and scaffolds are needed temporarily( to provide access to the workplace, the placement of the necessary tools and materials), their designs should provide for the dismantling and reuse of materials.
The device for scaffolding can be wedge .This type is characterized by high load capacity, stiffness and reliability. pins provide high mobility through simplicity of assembly and dismantling from standardized elements.
The frame design of the scaffolding is light in weight. For complex facades clamping aids are used, which are individually adjustable. An important characteristic for all types of forests is the stability and strong abutment of these structures to the wall surface.
The structural calculation of scaffolds for industrial use is carried out taking into account all of the above requirements. Consider the maximum number of employees, the required number of materials, tools and equipment. For forests with metal elements, even lightning protection is required. The thickness of the floorboards must ensure its rigidity, work platforms are equipped with external protective handrails, etc.
Scaffold Scaffold Scheme - what you need to know before working
For mounting, for example, tubular spatial structures from racks and crossbars, connected on hooks and nipples without a bolt method, a scheme of scaffolding is developed taking into account facade features. According to the rules, before draining, drainage, planning and careful compaction of the surrounding soils is carried out, since the estimated load can be over half a ton per meter of the stage. And this, if a special boom is not equipped to lift cargo.
Showing in what order and how to collect scaffolding, the drawings are used to break up the axes, the overall marking and laying of the supports and support pads, the mounting of shoes under the struts. The accuracy of the performance of these works is important for the subsequent installation of horizontal crossbars, fences and flooring.
As a rule, the height of the racks is from two to four meters. They should be installed and fastened to the shoes with special anchor wall fasteners.
Scaffolding scheme can include standard support braces, increasing the overall rigidity of the entire frame structure. The pitch between the pillars is determined by the length of the crossbars, but in general it does not exceed two meters. The width of the flooring should ensure the possibility of safe manipulation and work( up to one and a half meters).
The recommended thickness of boards is not less than forty millimeters. During installation, the verticality of the pillars and the leveling of the crossbars are verified by means of a plumb and level. For racks, an insignificant( up to two millimeters) convergence at the top is permissible, and deviations of other elements can be up to three millimeters.
Scaffolding construction with own hands - get down to work
These descriptions give an insight into how to make scaffolding. With regard to scaffolding, one can say that these single-tier structures are designed for work requiring movement along the front of their execution, such as bricklaying, interior finishing, etc. It is clear that the scaffolds must be sufficiently long and wide, have increased strength and rigidity along with stability and light weight, equipped with convenient steps or steps.
Homemade scaffolding is usually made of wood. Their use is justified at a height of buildings up to ten meters, i.е.when low-rise buildings. For racks, a long beam with a cross section of 0.1 × 0.1 m or a round timber of the appropriate diameter is used. For the stability of the supports their ends can be sharpened and dug into the ground. It should not be allowed to increase the distance between the upper ends of the supports: it is better if they slightly converge to the top. The top parts of the adjoining racks, necessarily fasten to a wall.
At the level of each tier( up to 2.5 meters high) cross bars are installed. They form a band around the perimeter. On racks such cross-pieces are strengthened by a board not less than forty millimeters thick. The same board should be used for flooring. If its length is not limited to two meters, it may be necessary to arrange the braces( the same forties).
All fastenings are better performed on galvanized screws, allowing after the completion of the work to dismantle the structure. How to install scaffolding with your own hands, the video will show more clearly. Do not forget about a reliable, durable and comfortable lifting and descent from the scaffolding and scaffolding.
