Specific requirements, the civil code is what ah! Thank you very much, I am lack of this kind of information, I hope you can tell me which of the following
5.2.5 scaffold EngineeringA. accessories(1) selection and calculation basis of structural parts1) selectionThe project uses 48 mm, 3.5mm wall thickness steel pipe and the corresponding fasteners, dense mesh safety net, big eyes, etc.. Among them, the specification of the steel pipe is from 0.5m to 6m, and the fastener mainly has a rotating shaft, a cross and a joint fastener. Bowl buckle scaffold also uses Phi 48, 3.5 wall thickness of steel pipe and the corresponding fasteners, mainly with 1 x 1.0m, 1.2 x 1.2m, 1.5 x 1.5m and other specifications. Foot board mainly 2M and 3M two.
The surface of the steel pipe shall be smooth and free of cracks, scars, delamination, dislocation, hard bending, burrs, indentation and deep scratches.The outer diameter of steel pipe 48mm allowable deviation is 0.5mm; the thickness of the wall 3.5mm allowable deviation of.0.5mm; steel pipe surface cutting oblique deviation 1.7mm;Dressing should be checked once a year. When the examination, should be in serious pipe corrosion in the selected three roots in each part of the serious corrosion of transverse sampling inspection, the outer surface of the steel pipe corrosion depth allowable deviation is less than 0.5mm, more than the provisions shall not be used.All new and old steel pipes must be painted with anti rust paint.
Inspection and acceptance1) the relevant provisions on inspection of steel pipesSteel pipes, fasteners, safety nets and other products must have a certificate of quality.All components must have quality inspection report, steel material inspection method must comply with the national standard "metal tensile test method" (GB/T228) the relevant provisions of the quality should be consistent with the "carbon structural steel" (GB/T700) regulations Q235. a steel.The surface of the steel pipe shall be smooth and free of cracks, scars, delamination, dislocation, hard bending, burrs, indentation and deep scratches.The outer diameter of steel pipe 48mm allowable deviation is 0.5mm; the thickness of the wall 3.5mm allowable deviation of.0.5mm; steel pipe surface cutting oblique deviation 1.7mm;
Calculation basisScaffolding input: for the template support part of the steel pipe material in accordance with the 1.5 layer of the amount of consideration: the amount of external scaffolding steel pipe in accordance with the full closed scaffolding consideration; safety net in accordance with the external scaffolding full consideration.
