Exterior wall scaffold construction plan?
Big bar:The large cross bar is arranged above the cross bar, and the inner side of the vertical rod is fastened with a right angle fastener and a vertical rod, and the length of the utility model is not less than 6m of the span of the 3m. The large cross bar is connected with a butt fastener, and the joint is arranged in a staggered way, not in the same time and in the same distance. The horizontal distance of adjacent joints shall not be less than 50cm. The distance from the joint to the riser is not more than 50cm
Vertical pole:Double row scaffolding pole, pole top high eaves 1.5m structure. Single tube base for vertical rod bottom. The vertical rod joint is connected with a butt fastener, and the vertical rod and the large cross bar are connected by a right angle fastener. When the joint is staggered, the two adjacent column joints are avoided to be in the same span, and the distance between them is not less than 50cm; the distance between each joint center and the main node is not greater than 60cm.
Foundation treatment:Pit backfill every 30cm thick layer by ramming into vibration compaction, compaction by cutting ring sampling test, the bearing capacity of Rammed Soil reached 60270KN/m2. And then in the compacted soil C15 cast in situ concrete hardening, thickness 100mm. The foundation of all scaffolds must be smooth. On the basis of the base plate, the thickness of not less than 50mm, the layout must be smooth, shall not be suspended; and in the periphery of the scaffolding outside the vertical rod 50cm set up a shallow ditch drainage.
