Shenzhen east lake scaffolding telephone: 18420150310 alpine construction steel pipe pile in the building, structure, steel structure, bearing, drainage, etc, is very popular application. Main materials include carbon steel, stainless steel, alloy steel. The most used widely with carbon steel material. Below small make up to introduce the construction of steel tube standard scaffolding specific specification and the erection process. Construction of steel tube standard scaffolding specific specifications: 1. Is in the fastener type steel pipe scaffold design and construction of carrying out the national technical and economic policy, to advanced technology, reasonable economy, safety, ensure the quality, specifications are formulated. 2. This specification applies to the console (for industrial and civil building construction Bottom brace type) Single or double row of fastener type steel pipe scaffold design and construction, as well as the level of concrete structure design and construction of formwork during the construction. Single row scaffolding shall not apply to the following conditions: ( 1) The wall thickness is less than or equal to 180 mm; ( 2) Building height more than 24 m; ( 3) Hollow bricks, aerated block wall lightweight wall; ( 4) Masonry mortar strength grade is less than or equal to the M1. 0 brick wall. 3. Fastener type steel pipe scaffold before construction, should according to the provisions of this specification to the scaffolding structures and stud design calculation of subgrade bearing capacity. 4. Fastener type steel pipe scaffold before construction, should according to the provisions of this specification preparation of construction organization design. 5. Fastener type steel pipe scaffold design and construction, besides should comply with the provisions of the specification, it should comply with the current national regulations on compulsory standards. Scaffolding set-up process: 1. Erection of scaffolding must be added a base or foundation, and the foundation of treatment. This project poling brace on the foundation slab directly or old soil, foundation pit bottom add tie bearing. Old soil surface laid foundation pit bottom plate must be smooth and shall not be suspended, placed the base should be pull and pull rod, spacing dimension by the regulation to be fixed after placement. 2. Steel pipe scaffold erection sequence is: put sweeping pole ( Close to the ground of the ledger, the height of 20 cm) And by the root set upright, then to sweep the floor and rod fastening of the small bar and rod or sweep the floor rod fastening - the first step of ledger (Ann With the vertical pole fastening) The first step to Ann putlog - the second step of ledger Ann - adding temporary inclined strut ( Upper end and the second step main rail fastening, in installing two wall behind the bar can be dismantled) - the third step, four main rail and putlog to wall rod with Ann, Ann, put the stud - added a bracing - scaffolding plank. 3. Stud set must be equidistant to straight, the longitudinal spacing shall not be greater than 1. 8m。 Poling horizontal spacing of 1. 0 m, the stud from metope to 40 cm. Small rail vertical spacing ( The scaffolding interval) 1. 8 m, shall not be greater than 2 m, where the underlying step putlog pick out the inside and the length of the stud shall not be less than 30 cm and 15 cm respectively. Scaffold outside every 9 m must establish a bracing, and the ground should be controlled in 45 ° Angle - 60 ° between top-down set in a row. Edit summary: the above is the small make up this paper introduces the construction of steel tube standard scaffolding set-up process, the specific norms and pay more attention to practical knowledge please Dr Ladder information.
