　　Construction Technology of Steel Skeleton Lightweight Plate

　　Laying out → Installation of lightweight boards → Adjustment of board seam distance → Welding → Jointing → Waterproof coating → Acceptance.

　　Laying out: After the handover with the previous process is completed, according to the layout diagram, lay out the position of the board edge, and at the same time check whether the layout diagram intersects with the on-site structure.

　　Installation: Use lifting equipment to gently place the lightweight board onto the steel frame nearby. When the crane cannot be directly positioned, lift the lightweight board onto a specially designed roof transport truck and then move it to the installation position.

　　Adjust the distance of the board joint: According to the requirements of Beijing 05sg3, adjust the board joint to the allowable deviation range, and the width deviation of the board joint shall not exceed 10mm.

　　Welding: After installation, according to the connection requirements of the "Steel Skeleton Lightweight Plate Atlas" Jing05sg3 for steel skeleton lightweight plates, weld the plate to the steel roof truss.

　　Jointing: Pour the prepared lightweight BAS core material into the board joint, and use steel bars to firmly insert the mortar during pouring.

　　Brushing waterproof coating: After adjusting the BAS polymer coating according to the usage requirements, apply it twice on the surface of the BAS core material, and wait for it to form a film.

　　8.1 The main ribs of the lightweight steel frame plate shall be sandblasted for rust removal, and the surface of the steel main ribs shall be thoroughly rust removed, with a rust removal grade of St3. If rust is found during use, measures should be taken in a timely manner. The connection between the steel main rib and the end rib, as well as the stiffening rib, is welded with a welding foot size of 4mm full

　　Welding, the welding quality complies with the relevant current national standards.

　　8. Welded steel wire mesh is used inside the lightweight steel frame slab, with short span small b Sa} 150 as the lower reinforcement, and the length extending into the support shall not be less than SOmm; Long span b 3 secret 200 is the upper reinforcement, which extends into the support for a length of not less than 30mm, and is welded one at a distance from the edge ribs unless otherwise specified.

　　8.3 The suspension rod of the steel skeleton lightweight board ceiling should be connected to the edge ribs and should not be connected to the core board.

　　When stacking lightweight plates with a steel skeleton of 8.4 SB, the height of each stack should not exceed 10 pieces, and wooden pads should be placed flat and aligned vertically. During loading and transportation, the overhanging length of the board should not exceed 300mm.

　　When lifting the lightweight steel skeleton plate with a size of 8.5 GD, a special lifting device should be used to lift at four points, with no more than two pieces lifted at a time.

　　8.6 Steel skeleton lightweight panels can only be shipped when the core material strength reaches 950/of the design strength. SB steel lightweight composite panels should be prevented from friction and collision during transportation and installation. Any paint peeling or local damage caused by friction or collision should be repaired in a timely manner.
