Manufacturing, transportation, storage, installation, and maintenance of steel frame light panels, steel frame light roof panels, steel frame light floor panels, and steel frame light grid panels:

  The steel frame is constructed using either welding or bolted connections. When welding is employed, the cold wind quality grade is Class 3, with the weld seam height being...4mm、

  Steel wire mesh within the panel5With round3Welded wire mesh, featuring round...5For reinforcing steel subjected to load, the length extending into the support shall not be less than50mmComma3For distributed reinforcing bars, the depth into the support should not be less than30mmAnd there should be a transverse rib within the bracket.

   To ensure the integrity of the core material, the upper layer should be poured before the lower layer begins to set.

   The core material of the roof panels and the outer surface of the wall panels is poured higher than the steel frame.20mmThe thickness of the reinforcement protective layer ≥20mmNo random holes are allowed on the steel frame light gauge panels; when the hole size isD＞200mmIf necessary, a separate design should be created, and provisions should be made in advance during installation. Special cases requiring on-site drilling should be completed in collaboration with the manufacturer.

  The steel frame frame should be treated for rust removal, with the rust removal grade being:st2.c06-1Two coats of iron red alkyd anti-rust paintc04-2Two coats of alkyd magnetic paint in various colors, film thickness:120μmThe steel frame and core material contact surfaces are not painted.

  When the core material reaches the designed strength70%When ready for transportation or hoisting. During exclusive vehicle transportation, wooden blocks should be placed inside the vehicle, lightweight boards should be stacked flat and securely tied down, and the overhanging length of the lightweight boards should not exceed600mm。

  Steel frame lightweight panels should be handled using machinery for second transportation and lifting, with individual panels lifted separately.

  The steel frame light panels should be stacked on a level and firm site. The height of each pile should not exceed...10Blocks, the height of the battens must be consistent and aligned vertically.

  During the installation of steel frame lightweight panels, the length of the panel resting on the support frame must not be less than60mmAfter positioning, the main ribs of the roof and floor should be securely welded to the supports, with the weld length not less than60mmWeld height:4mm, and shall ensure3Spot welding. Strengthen the overall connection points for roof and floor panels that require seismic resistance.

  Roofing panels should be sloped structurally; the slope must not be less than2%The waterproof layer can be directly placed on the roof panels. During transportation and installation, the steel frame lightweight panels should be prevented from collision. In case of paint peeling or localized damage to the panels due to friction or collision, the paint should be promptly reapplied after installation, and the localized damage should be repaired according to specifications.

  Steel frame light panels cannot be used directly as working surfaces for earth construction. When construction materials are stacked and transported on the panels, protective measures must be taken, and the stacking weight and construction load must not exceed the standard value of the allowed additional uniformly distributed load combination for the panel.

  Measure the main structure before construction, ensuring that embedded parts allow for position deviation in the vertical direction.±10mm, ± horizontal5mm。

  Before installing the steel frame lightweight exterior wall panels, all preparatory work should be completed. Connectors and matching materials must be ready, and level and height control lines should be set out. The exterior wall panels should be properly aligned and positioned. Attention should be given to the installation sequence. After the panels are positioned, secure them temporarily before removing the hoist hooks, then fasten them according to the specified connection methods.
