Picture of Prefabricated Steel Skeleton Lightweight Plate in Nanyang, Henan Province

Description :

　　What is the construction process of prefabricated steel frame lightweight slab in Nanyang, Henan?

　　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. Advantages of Steel Skeleton Lightweight Board Roof Panels

　　1. By adjusting the cross-sectional dimensions of purlins to meet the needs of loads and engineering, the problem of existing lightweight steel frame slabs under large roof loads and column spacing can be solved. Strong structural integrity. Suitable for buildings with various spans and column spacings.

　　2. Steel skeleton lightweight plateroof panelThe customized specifications of 90% fixed length and 10% irregular shape have strengthened the uniformity of specifications, reduced the customization cycle, and accelerated the production and construction speed.

　　3. Mechanized production can be achieved, and standardized bentonite roof panels will be more aesthetically pleasing.

　　4. The board specifications refer to the container specifications and can be transported by train and ocean going cargo ships for longer distances without damage (including exports).

　　5. Optimized board joint treatment method makes construction more convenient.

　　2. 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.
