Steel skeleton lightweight plate-Application of Explosion Wall

　　Steel skeleton lightweight panel explosion-proof wall: A lightweight pressure relief wall (weighing no more than 60kg/㎡ and usually consisting of single-layer panels, sandwich panels, single-layer panels, and insulation wall panels) commonly used in industrial and civil plant boiler rooms, hazardous goods warehouses, etc. The explosion-proof pressure value of steel skeleton lightweight panel is usually between 20-40psf. When gas pressure rises sharply inside the building during combustion, the steel skeleton lightweight panel explosion-proof wall opens and releases pressure through explosion-proof fittings or devices to control the occurrence or minimize the degree of damage. Explosion relief accessories are usually composed of explosion relief bolts and traction ropes. The explosion relief bolts quantify the explosion relief pressure value and dynamically control the release pressure; The function of the noose is to restrain the splashing and injuring people and objects on the opened wall! The core plate is made of inorganic material, with good stability, aging resistance and service life equal to that of concrete material

　　Diameter of steel wire at the bottom of the board

　　Above, the thickness of the protective layer

　　Above and with a moisture absorption rate lower than

　　The board has strong resistance to gas corrosion such as acid and alkali

　　After the second freeze-thaw cycle, there was almost no change in volume and strength.

　　The board has excellent insulation performance, low thermal conductivity, and the overall heat transfer coefficient of the board can reach

　　Meet the insulation and energy-saving requirements of buildings in high-altitude regions

　　The board has excellent thermal insulation performance, and the outer side of the board is heated to

　　At that time, the temperature inside the board was only

　　It is an ideal building insulation material for high-temperature areas.

　　Waterproof:

　　The core board is made of inorganic material, which is non combustible and does not burst or release toxic gases in fire, making it an excellent refractory material; The fire resistance of the entire board is greater than

　　Hours, meeting the first level fire protection requirements of the components. The steel frame lightweight plate comes with a dedicated one when it leaves the factory

　　The composite anti-seepage coating, combined with the overall waterproofing method of the roof, forms a reliable composite waterproofing system, solving the problem of leakage of general lightweight boards.

　　The main ribs of the lightweight steel frame plate are rust removed by sandblasting, and the surface of the steel main ribs should 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.
