Erection program
(General content)

1. Prepared according to: the preparation of the program is based on laws, regulations, standards, specifications and documents, drawings, etc..
2. Project Overview and conditions: according to the actual situation on site was clear.
3. Scaffold floor plan (indicating)
4. Scaffolding components and parts quality standards
4.1 steel and fastener
Diameter steel pipe should use 48mm, wall thickness 3.5mm welded steel pipe, should adopt a moderate mechanical properties
Q235A (3 #) steel, its mechanical properties should be consistent with current national standards "negative carbon structure steel" GBT700 in the provisions of Q235A steel, fasteners should conform to GB15831-1995 "Steel Scaffolding Coupler" requirement.
4.2 base
Steel tubular scaffolding base has a standard malleable iron manufacturing base and welding the bottom two. Standard cast iron base materials may be requested with the same fastener. Q235A steel welded base should be used, electrodes should be used E43 type, geometry should be consistent with shock-inch icon
