First, an overview of the construction technology
(1) Construction preparation: including material preparation, technical preparation, personnel preparation, etc., to ensure smooth progress.
(2) Erection process: follow a certain erection sequence and principles, such as first vertical poles and then horizontal poles, first bottom floor and then upper floor, etc., to ensure the stability and safety of the scaffolding.
(3) Dismantling process: dismantle in the opposite order of erection, paying attention to safety issues and details during the dismantling process.
Second, site survey
(1) Geological conditions: understand the soil type, bearing capacity and other geological conditions of the construction site to ensure the stability and safety of the scaffolding.
(2) Site environment: check whether there are obstacles such as high-voltage lines and underground pipelines around the site to avoid interference with the scaffolding construction.
(3) Climate conditions: understand the climate conditions during the construction period, especially severe weather such as wind, rain, and snow, and formulate corresponding preventive measures.
Third, material preparation
(1) Scaffolding: Prepare a sufficient quantity of scaffolding and accessories of qualified quality according to the construction drawings and actual needs.
(2) Connectors and fasteners: Prepare appropriate number of connectors and fasteners, such as fasteners, bolts, etc., for the assembly and fixation of scaffolding.
(3) Safety protection facilities: Purchase safety nets, safety baffles, safety warning signs and other safety protection facilities to ensure safety during construction.
Fourth, material quality requirements
(a) Steel pipes should be free of cracks, dents, and rust, and butt welding of steel pipes is not allowed.
(b) Steel pipes should be straight, and the allowable deviation of straightness should be 1.5L/1000 of the pipe length. Both ends should be flat and free of bevels and burrs.
(c) The surface of the casting should be smooth and free of defects such as sand holes, pores, shrinkage, cracks, etc., and the surface sand should be cleaned.
(d) Stamping parts should not have defects such as burrs, cracks, or oxide scale. (e) The effective height of each weld should comply with the regulations, the weld should be full, the flux should be cleaned, and there should be no defects such as incomplete welding, slag inclusions, undercuts, cracks, etc. (f) The surface of the adjustable base and adjustable bracket should be dipped in paint or cold-dip galvanized, and the coating should be uniform and firm; the surface of the frame rods and other components should be hot-dip galvanized, the surface should be smooth, and there should be no burrs, nodules and excess lumps at the joints.
Fifth, technical briefing
(1) Construction drawing review: Organize technical personnel to review the construction drawings and familiarize themselves with the structural form, construction requirements, and other technical points of the scaffolding.
(2) Construction plan formulation: Based on the construction drawings and the actual situation on site, formulate a detailed construction plan, including the construction sequence, construction methods, safety measures, etc.
(3) Technical briefing meeting: Hold a technical briefing meeting to convey the construction plan and technical requirements to the construction team to ensure that the construction personnel have a full understanding and mastery of the scaffolding construction process.
