Scaffold construction plan is the construction of construction workers, the behavior of the standard, is the guarantee of the construction process to build employee safety and health. The scaffold construction materials mainly include scaffolding and safety net. The erection process is common cantilever frame, main stem base, stud spacing, bar set, shears, laying requirements, guardrails, even the wall pieces, enclosed in the body. So what are you know scaffold construction requirements? 1. Steel pipe floor scaffolding 48 mm outside diameter, wall thickness 3. 20 mm, steel strength grade q235 - a。 Profile steel pipe should be flat, smooth, no cracks, no separation, no creasing, identification mark whatever logo, hard to bend. Scaffold before construction, steel tube sample should be sent to the experimental unit with relevant national qualification for steel pipe bending strength and tensile strength of the mechanics experiment. Only experimental function satisfaction planning requirements, steel pipe can be used in the construction. 2. Steel pipe scaffold device project plastic fasteners, should be suitable for promotion jgj22 - purchase often-expensive firmware scales of steel tube feet 85 requirements, the manufacturers supply fasteners production license, can not have crack, air hole, shrinkage, sand holes, forging defects such as the standard steel fasteners should match, and should be doing, everything about the hook on the spot, open grip of short distance not less than 5 mm. When steel bolt tightening torque to reach 70 n. M, shall not be damaged. When operating the old fasteners, need to sample of fasteners, to send relevant national qualification inspection unit of the sliding resistance of fastener. Experimental function only satisfied with the planning requirements, can be used in the construction. 3. Frame should be done before setting up nursing, corrosion and coating, the color environment better. Scaffold pole, guardrails, kicking pole consistent paint for yellow, shear consistent support for orange red paint. Row at the bottom of the pole and sweep pole painted red and white. 4. Selects the pedals and pedals to satisfied requirements. 5. Safety net should choose dense type, mesh should be satisfied with 2000 mesh / 100 cm2. Through experiments cannot penetrate. Flame retardant safety net to hold production license and certificate of quality, and have wenzhou building security dot holed up part of the release permit. 6. Join wall body parts with steel pipe should be operating, the material shall be suitable for current national scale carbon steel structure ( GB / T 700) The requirements of Q235A steel. 7. Degree of section steel cantilever choose 16 a channel steel, choose five diagonal. Six Angle steel, 56 * 3 * 6. 0 mm steel pipe. 8. Embedded bolt diameter of 20. 0mm。
