Because the steel skeleton light plate is poured in layers, and the foamed concrete layer is self-flowing pouring, which is very important for improving the deep waterproof performance of the steel skeleton light plate. During the pouring process of the steel skeleton light plate, the formation of the impermeable stratosphere is completely formed by relying on the natural flow of the liquid core material.

The whole molding process of the lightweight board does not even require too much human intervention, and the core material itself can be molded by itself with the advantage of good fluidity. After the natural leveling of the core material, a dense stratolayer will be formed on the surface of the plate, and its internal structure is stable and compact, and it is difficult for external substances to penetrate into it.

<> is a new type of lightweight energy-saving building material, it is not only energy-saving, but also fireproof, waterproof and even in the earthquake resistance can see it, so it is widely used in industrial plants, transportation, building walls and other side branches. It maintains the advantages of traditional reinforced concrete for a long time and has a long service life, and also meets the needs of modern industry for energy saving and light weight.

Nowadays, in response to the requirements of some large-scale engineering projects, steel skeleton light plates have successively developed a series of products such as large roof panels, floor slabs, explosion venting boards, etc. It solves the problems of fear of pressure and breakage when selecting materials, and may be applied to dangerous projects. There are better development prospects in petroleum, aviation, food, chemical and other industries.

The steel skeleton light plate has been patented by Beijing Tianji Company, so it is also called "Tianji board". It has stronger load-bearing capacity, strong compressive capacity and long service life than ordinary color steel plates, so more and more people begin to choose to use steel skeleton light plates.

The applicable environment and classification of profiled steel plate load-bearing floor slab are made of galvanized steel plate by rolling cold bending, and its cross-section is V-shaped, U-shaped, trapezoidal or similar to these shapes of waveform, which is mainly used as floor bearing plate, and can also be selected for other purposes. The slab is used as a floor bearing plate, which is characterized by fast construction, convenient, short construction period, saving steel bars, and also being a steel formwork, and has the characteristics of low cost and high strength. The name of the profiled steel plate:

Color profiled steel plate, composite floor, floor deck, steel deck, profiled steel plate, floor plate, steel floor deck, galvanized profiled steel plate, combined floor plate, galvanized steel deck, galvanized floor deck, galvanized floor deck, composite floor deck, floor steel deck, profiled steel composite floor, etc., are divided into: open profiled steel plate, fully closed floor deck, dovetail deck, etc. Because the original plate is very thin, the quality of the anti-corrosion coating directly affects the service life, in order to meet the processing and anti-rust requirements, the coated steel plate needs to be inspected according to the relevant regulations.

Under normal circumstances, the thin steel plate can also be coated with anti-rust paint after being pressed according to the requirements of use, or the original stainless steel sheet can be used. When profiled steel plates are used as panels and wall panels in industrial factories, the amount of steel used per square meter is about 5 11 kg in the case of no insulation requirements. When there are insulation requirements, mineral wool boards, glass wool, foam plastics, etc. can be used as thermal insulation materials.

The profiled steel plate is combined with concrete to make a composite floor slab, which can eliminate the need for wood formwork and can be used as a load-bearing structure. At the same time, in order to strengthen the bonding force between the profiled steel plate and the concrete, it is advisable to pre-weld the bolts on the steel plate or press the two-way stiffener. Some industrially developed countries have a wide range of applications of profiled steel plates, not only in industrial and civil buildings, but also in vehicles, ships, instrument box wall panels and shells and civil appliances and other Chinese in Wuhan Iron and Steel Plant rice mill project, Shanghai Baoshan Iron and Steel Plant and Shenzhen Special Economic Zone and other projects of the roof and wall of a large number of use, the effect is good.
