It is impossible to carry out the finishing and repair work of buildings, with a height of more than two floors, without construction forests. If you have to work at an altitude of not more than 7 meters, then you can use wooden forests. They are the simplest and cheapest. Only before starting work it is worth making sure that the design of forests is stable.
Frame construction forests are much more reliable and more stable than wooden. They can withstand a load of 200 kg/m2 and consist of lateral frames and racks that are attached to each other horizontally and diagonally. The most common and convenient forests are building frame, popular thanks to cheapness and quick installation and dismantling. They gather in frames according to the “pipe into the pipe” method without the use of special tools and can be used in facade work on 60 meter buildings. Frame forests are flag, pin and tower. Forests of the latest generation also have a large support site, which increases the ability of each frame by half. Building frame are also good for the fact that they can combine with clamp forests.
Clamps are usually used for work on non -standard buildings, where there are arches and dome. The normative load of such forests is up to 250 kg/m2 and they can be mounted to a height of up to 80 meters. Their assembly is complex: crossbars and racks are connected by clamps and attached with threaded bolts.
The wedge building forests are the most complex designs are designed for a load of up to 300 kg/m2 and are used to work on high -rise buildings. The assembly elements are attached by steel wedges of a special shape, which are clogged with a hammer. In this way, increased forest strength is ensured. With what type of building forests should you decide, depending on the goals and objectives set, but you need to remember that all metal forests must be attached to the building. Only at a height of less than 4 m can you do without an anchor mount to the wall and then only on even and tamped sites.
