Due to its good stress-bearing performance, the amount of steel used per unit volume of the coupler scaffolding is about 40% of that of the bowl-buckle scaffolding. Therefore, the coupler scaffolding is suitable for higher-design support systems. After the buckle scaffolding is erected, it has a beautiful appearance and has become a beautiful landscape in a city that has extremely strict requirements for civilized construction. It is in sharp contrast to the dirty bowl-button scaffolding. Fasteners must be used rationally during the erection of the frame, and fasteners must not be substituted or misused. Sliding wire or cracked fasteners must not be used in the frame. Everyone knows that no matter what you do, there must be a sequence. Of course, the erection of the buckle scaffolding must also be carried out in accordance with strict erection specifications.
Erection specifications of coupler scaffolding:
1. When using coupler scaffolding to erect double-row exterior scaffolding, the height should not be greater than 24m. If it is greater than 24m, additional design calculations must be made. The user can select the geometric size of the frame according to the usage requirements. The step distance between adjacent horizontal poles should be 2m, the longitudinal distance between vertical poles should be 1.5m or 1.8m, and should not be greater than 2.1m, and the horizontal distance between vertical poles should be 0.9m or 1.2m.
2. Pole: The bottom of the pole should be equipped with an adjustable base. The first floor poles should be staggered with poles of different lengths, and the vertical distance of the staggered poles should be greater than or equal to 500mm.
3. Diagonal rod or scissor brace: A vertical diagonal rod should be installed on each floor every 5 steps along the longitudinal direction of the outside of the frame or a fastener steel pipe scissor brace should be installed every 5 steps. Vertical poles should be installed on each layer in the transverse direction of the end span. Inclined rod.
4. Connecting walls: The setting of connecting walls should meet the following requirements: connecting wall parts must use rigid rods that can withstand tensile and compressive loads. The connecting wall parts should be kept vertical to the scaffolding and the wall. The connecting wall parts on the same floor should be on the same floor. On the same plane, the horizontal distance should not be greater than 3 spans, and the distance from the outer side of the main structure should be less than or equal to 300mm.
