Installation requirements for light steel frame panels

 Steel frame light plate device process, production, transportation, accumulation, device, protection: wiring - lifting - positioning - fixed (such as welding) - welding seam treatment - filling plate joint

2.1 The steel skeleton shall be connected by welding or bolt, and the weld quality grade shall be level 3 and the weld height shall be 4mm.

2.2 Layered casting is adopted for core material. In order to ensure the wholeness of core material, the upper layer should be poured before the initial setting of the lower layer.

2.3 The thickness of the protection layer of the force bar is ≥20mm.

2.4 Holes shall not be opened randomly on the steel frame light plate. When the size of the hole IS D > 200mm, the holes shall be reserved during production; In special circumstances, the hole opening on site should be completed by the cooperation of the manufacturer.

2.5 Steel frame frame should be derusting, rust removal grade is ST2, two lines of C06-1 ferric red alkyd antirust paint, two lines of C04-2 colored alkyd enamel paint, film thickness is 120μm, steel frame and core material contact surface is not painted.

2.6 When the strength of core material reaches 70% of the planned strength, it can be transported. When loading and transporting, cushion wood shall be installed in the car, and the light plate shall be piled flat and tightly bound. The cantilever length of the light plate shall not exceed 600mm.

2.7 During the secondary handling and hoisting of steel frame light plate, special machines and tools shall be choosed for single-block hoisting.

2.8 When the steel frame light plate is stacked, the place shall be flat and solid, and the stacking height of each stack shall not exceed 10 plates. The height of the cushion wood shall be the same and aligned up and down.

2.9 steel skeleton light plate, the plate placed on the bearing length should not be less than 60 mm, in place after the roof board, floor board advocate rib should be and pedestal (embedded parts in concrete beams) welded, the weld length of not less than 60 mm, weld height is 4 mm, and shall ensure that welding at three houses end, expansion joint and other similar parts, when welding difficulties, Effective methods should be adopted to fix the wall panels, flexible joints should be choosed, all plate joints should be watered dense, and the appearance of the closed treatment, for seismic fortification requirements of the roof panel, the floor should be strengthened according to the map of all joints.

2.10 Roof structure should be choosed to find slope, slope should not be less than 2%, waterproof layer can be directly made on the roof board.

2.11 The light steel frame plate shall avoid bumping during transportation and installation. If the paint falls off or part of the plate is damaged due to conflict or bumping, the paint shall be repaired in time after installation and the damage of the plate shall be repaired as required.

2.12 steel frame light plate can not be directly used as civil construction operation surface, if the accumulation and transportation of construction data on the board, should adopt the protection method, and its accumulation and construction load shall not exceed the plate allowed plus uniform distributed load combination standard value.

2.13 The main structure shall be measured before construction, and the main structure shall allow the error: ±10mm in the vertical direction and ±24mm in the horizontal direction. If the error is too large, the processing scheme shall be agreed with relevant units.

2.14 After the installation of the embedded parts is completed, the position error of the embedded parts should be allowed: ±10mm in the vertical direction and ±5mm in the horizontal direction.

2.15 Before the construction of light steel frame outer wall panels, all preparations should be made, the connectors and supporting materials should be ready, the level and height control lines should be released, and the outer wall panels should be placed in the middle number. Attention should be paid to the installation sequence, and the outer wall panels should be fixed temporarily and then removed from the hook after alignment, and then fixed according to the convergence practice of atlas rules.
