1, the basic structure
Fastener steel pipe scaffold has a single row and double bent in two, double row fastener type steel pipe scaffolding erection height should not be more than 50 m, horizontal stud spacing of 1.5 m, longitudinal vertical pole spacing of 1.5 m or less, small bar spacing of 1.0 m or less, the ledger interval 1.6 to 1.8 m, small bar to hang a wall 0.40 m long.

2.Demand, structure
(1) the vertical scaffolding rod
The foundation soil compaction leveling. And is equal to the drainage, and the foundation of the width is not less than 200 mm, 50 to 60 mm thick and area of not less than three times the base area of wood plate, shall not be arbitrarily at the bottom of the frame body near or mining operations, such as the need to dig, should draw up the frame body reinforcement measures, and implementation of the technology departments for approval.

(2) the vertical rod longitudinal distance
Height under 30 m, poling throw of 1.8 m.
30-50 m high: with stick, 30 to 40 m poling throw of 1.5 m.
40-50 m poling throw of 1.0 m.
With double poling: poling throw of 1.8 m.(bar at the top, since independence, 30 m with single pipe down, go down to the ground part of miles outside the poling double metal pipe, along the vertical wall of parallel and fastener tighten)

(3) the connection and the deviation of bar
The connection of stud
Poling except when on the top floor in the form of lap joint, the rest of the connection must be used when docking fastener each other should be staggered, namely phase led promulgation and link rod should not be in sync with up, adjacent promulgation and link rod, in the height direction should be staggered not less than 500 mm.
