In any large-scale facade construction, repair and rehabilitation work at height scaffolding is an indispensable device that allows you to ensure the safe lifting of workers to the desired height. All such designs have several classifications. Divide them by purpose, by type of construction, materials, basic elements for the lift height for the lift. It depends on these parameters, rational choice and security of work.
What are scaffolding
Scaffolding made from aluminium and steel. Sometimes, different people make them from wood to save.
Steel woods are:
- Frame
- Pin
- Wedge
- Clamp
Frame scaffolding
Not much different from other types of data structures, but the main difference is the finished welded frame. Due to this case just this type of scaffolding is called lightweight. More details to see what scaffolding is provided here. The most basic plus data of forests in low weight, due to this they have a lower cost in comparison with other types, but also their Assembly takes less time.
Pin forest
The name itself already suggests that in this type of forests is pin type connection. There is a view that the connection elements is welded pins. Their main advantages, it: quick Assembly, plus due to the different sizes of crossbars to make the work sites of different sizes. Horizontal linkages also are different sizes due to which they can be tailored to different types of facade.
V-forest
The main advantage of wedge scaffolding in the possibility of assembling any desired shape. Thanks to welded on the sides of the flanges can build forests in eight directions. Also in the wedge forests, you can increase the size of the working platform in the desired location due to the additional consoles that are made for them.
Clamp forests
Let’s start with the cons, and the main disadvantage in their speed of Assembly since all connections must be tighten with a wrench. Due to the large number of connections these forests are the most expensive cost. However, this type of scaffolding can be used in conjunction with any other type: wedge, pin and frame forests.
The purpose of scaffolding
The purpose of the forest can be for outdoor and indoor use. Some designs it is possible to apply both outside and inside buildings. The versatility of the designs adds to their modularity. Thanks to her construction may fit to any, even limited height.
By construction, the most commonly used scaffolding frame, clamp, pin type. Selection of a particular form depends on the complexity of work performed and configuration of the wall. So, for straight facades, a good option would be the use of frame structures. But since their equipment can log a large number of elements, it is possible to become and building a more complex surface. In relation to the curvilinear facades, here is a band worthy of the attention of forest. They allow you to assemble any configuration of the wall. To perform large-scale works in large areas of the walls, the capital construction better suited the male facade scaffolding. They are more rigid and have a high load-carrying ability. Also worth mentioning about the tower tours, which are irreplaceable for work at height to 20metrov.
Scaffolding work
Features scaffolding and lifting height. It can range from 30 to 60 meters. A specific value for each type may vary depending on configuration, the material of the main load-bearing parts and their sizes.
Most often they are made of steel elements. Load-bearing (supporting) part made in the form of tubes of different cross sections (circular, rectangular, profile). This allows you to make a piece as strong as possible, able to withstand all kinds of loads, including wind. Lightweight models made of aluminium. They are easy to assemble and dismantle, hard enough. A small minus — the higher cost.
An important characteristic of any forest is their capacity. Bearing capacity depends on type of construction, its size, lifting height. The most durable considered to be the male facade scaffolding, which can take up to 600kg per square meter of flooring. Such designs serve to be placed on them as employees, equipment, and heavy construction materials. Belts and frame facade scaffolding and lifting less able to perceive the load order of 200 — 400 kg per square meter of flooring.
