Steel pipe scaffolding selection requirements
The foot of the steel pipe is placed on the floor, and the outer diameter is 48mm, the wall thickness is 3.20mm, and the steel strength grade is Q235-A. The surface of the steel pipe should be straight and smooth, and there should be no cracks, delaminations, indentations, scribes and hard bends. Newly used The steel pipe must have factory certificate. Before the construction of the scaffold, the steel samples must be sampled and sent to the testing unit of the relevant national qualifications to carry out mechanical tests such as bending resistance and tensile strength of the steel pipe. The test results can meet the design requirements before they can be used in construction. The use of malleable cast fasteners for erection of steel pipe scaffolds in this project shall comply with the requirements of the “Standard for Fastening Steel Pipe Stakes†JGJ22-85 by the Ministry of Construction, and shall be provided by the manufacturer with the fastener production license, without cracks, pores, and shrinkage. For forging defects such as loose and sand eyes, the specifications of the fasteners should be matched with the steel pipe, the surface of the paste should be dry, the active part should be flexible, and the distance between the opening of the pipe clamped should not be less than 5mm. Tightening torque of steel pipe bolts up to 70N.m must not be destroyed. If the old fasteners are used, the fasteners must be sampled and sent to the test unit of the relevant national qualification to carry out tests such as anti-sliding force of fasteners. The test results can meet the design requirements before they can be used in construction.
