The steel pipe scaffolding test machine is a machine that uses right-angle fasteners, rotary fasteners, butt fasteners and bases to detect all mechanical properties of anti-slip, anti-destructive, torsional stiffness, tensile and compressive for scaffolding with an outer diameter of 48.3mm. Do you know the "basic situation" of the steel pipe scaffolding test machine? Let's learn about it.
Ordinary cantilever
l. Steel pipe foot flooring handrail, with an outer diameter of 48mm, a wall thickness of 3.20mm, and a steel strength grade Q235-A. The surface of the steel pipe should be straight and smooth, and there should be no cracks, layering, indentation, scratches or hard bends. New steel pipes must have factory certificates. Before the construction of the scaffolding, the steel pipes entering the site must be sampled and sent to the test units with relevant national qualifications to conduct mechanical tests such as bending and tensile resistance of the steel pipes. Only after the test results meet the design requirements can they be used during construction.
2. The installation of steel pipe scaffolding in this project uses forged cast fasteners, which should comply with the requirements of JGJ22-85 of the Ministry of Construction's "Security for Steel Pipe Scaffold Fasteners" by the manufacturer with a fastener production license. It must not have forging defects such as cracks, pores, shrinkage, sand holes, etc. The specifications of the fasteners should match the steel pipe, the bonding surface should be dry and tidy, and the moving parts should be flexible. The small distance at the opening when clamping the steel pipe is not less than 5mm. The steel pipe bolt tightening torque reaches 70N.m. shall not be damaged.
If used fasteners, the fasteners must be sampled and sent to the test unit with relevant national qualifications to conduct tests such as anti-slip force of the fasteners. The test results can only be used during construction after they meet the design requirements.
3. Maintenance should be carried out before erecting the shelf, rust removal and color uniformly, and the color should be beautiful in the environment. The scaffolding poles, protective railings and skirting poles are painted yellow in uniform, and the shearing support is painted orange in uniform. The bottom row vertical poles and sweeping poles are painted red and white in color.
4. The scaffolding boards and scaffolding tablets meet the relevant requirements.
5. The safety net adopts a dense-mesh safety net. The mesh should meet 2000 mesh/100cm2. The penetration resistance is not penetrated. The weight of a single net of 1.6×1.8m is more than 3kg. The color should meet the environmental effect requirements and use green. It is required to be flame retardant. The safety net used must have a product production license and quality certificate, as well as a license issued by the national construction safety supervision and management department.
6. The wall connecting parts are made of steel pipes, and their material should comply with the requirements of Q235A steel in the current national standard "Carbon Steel Structure" (GB/T 700).
7. The horizontal cantilever rod of the steel is made of No. 16a channel steel, and the inclined rod is made of 5.6 angle steel 56 × 3 × 6.0 mm steel pipe.
8. The diameter of the embedded bolt is 20.0 mm.
