Single-row scaffolding: scaffolding with only one row of vertical poles, the other end of the horizontal flat pole rests on the wall structure. It is rarely used now and can only be used for temporary protection.
Double-row scaffolding: It consists of two rows of vertical poles and horizontal poles inside and outside. The double-row scaffolding has two rows of vertical poles, large horizontal poles, and small horizontal poles, some are floor-standing, some cantilevered, and some are climbing, which are selected according to the project conditions.
Compared with the general structure, the working conditions of scaffolding have the following characteristics:
1. The load is highly variable.
2. The joints connected by fasteners are semi-rigid, and the rigidity of the joints is related to the quality of the fasteners and the installation quality, and there is a large variation in the performance of the joints.
3. The scaffolding structure and components have initial defects, such as the initial bending and corrosion of the rods, the size error of erection, and the eccentricity of the load.
