The Scaffolding Jack Foundation Shall Conform To The Requirements Of The Construction Plan
1. When the height is below 25m, the topsoil compacted, and the top layer is 50mm x 20mm thick planks. The length is 2m when the length is perpendicular to the wall; Parallel to the wall when the length is greater than 3m.
2 Set-up in 25 to 50 m 2, should be based on the situation to endurance design basis to practice or use backfill soil layered solid requirements, available sleepers bedding, or 20 cm, the desire that add a store on the ground on the laying of concrete plate, then lifted up 12 ~ 16 channel steel.
3 the base of the tubular steel pipe scaffold has two kinds of malleable cast iron manufacturing and welding base, set-up when wooden plate should be smooth, put a good base, then in the stud in the base, are not allowed to post directly on the wood, otherwise will change the plate stress state. Under the base of the setting pad, the load transfer is favorable. Under the standard base, the wooden gasket (5cm in thickness and the length of plate is greater than 200cm) can increase the bearing capacity of foundation soil more than five times. When the length of the board is greater than 2, it will help to overcome the uneven settlement between the two poles.
4 When the upright rod is not buried, the vertical and horizontal sweep rod shall be set at 20cm from the ground. Set sweeping bar is the same as the main rail and putlog, its role in fixed at the bottom of the stud, constraint poling horizontal displacement and settlement, seen from the experiment, no sweeping the floor of the scaffold screw jack carrying capacity has dropped.
5 If the wooden scaffolding pole is buried, the floor is not set. The buried depth of 30 ~ 50cm, the bottom of the pit should tamp down the brick, and the backfill in the pit should be layered and compacted. When the foundation of the scaffold is low, it should be considered that there are drainage measures around it, and the wooden scaffolding pole shall be buried in the backfill soil to prevent the water from accumulating on the ground.
