Scaffold is mainly composed of base plate, base, upright, large cross bar, small cross bar, slant support, throw bracing, cross bracing, wall connecting rod, bottom sweeping rod and its accessories.
Scaffold is mainly composed of base plate, base, upright, large cross bar, small cross bar, slant support, throw bracing, cross bracing, wall connecting rod, bottom sweeping rod and its accessories. The functions of each component are as follows:
Pole: Vertically set, it is the main load-bearing member of the scaffold, which transfers the load to the foundation through the base and cushion plate.
Large horizontal bar: parallel to the wall, connected to the upright to form a whole, transmitting the load of the scaffold board to the upright.
Small crossbar: perpendicular to the wall, directly bearing the load of the scaffold board and transmitting it to the large crossbar; In the double row rack, it also serves to connect the inner and outer rows and enhance overall stability.
Slant support: it is set diagonally close to the external upright tube (with an angle of 45 ° – 60 ° to the ground), and is mostly set at the corner to prevent the scaffold from longitudinal inclination and bearing horizontal force.
Scissor brace: A double diagonal brace set at an angle of 45 ° -60 ° with the ground on the outer side, which can connect the scaffold as a whole, enhance stability, and withstand horizontal forces.
Throwing support: the ground diagonal brace (about 60 ° to the ground) is used to improve the horizontal stability of the scaffold and prevent it from tilting outward; The initial stage of construction and the later stage of demolition are particularly crucial. Usually connected to a vertical pole through a horizontal support to enhance stability.
Wall connecting rod: reliably connected to the main structure of the building with a vertical spacing of ≤ 4 meters and a horizontal spacing of ≤ 7 meters, capable of withstanding tension and pressure, transmitting wind loads, and additional loads caused by uneven settlement of the pole.
Sweeping pole: a vertical horizontal pole close to the ground, used to enhance the stability of the base of the pole, prevent the pole from shaking or settling unevenly.
Scaffold board: laid on small horizontal bars, directly bearing construction loads and providing a work surface.
