The invention relates to a floor board used in the field of building, in particular to a light composite floor board suitable for light steel construction field or wooden structure house formed by special structural design and plate application.

At present, the cold-formed thin-walled steel structure house slab generally adopts the following technology: the plate is locked on the cold-formed thin-walled steel rafter, and the plate is generally selected as an oriented strand board (OSB board) or a wooden splint or a precast cement board as a substrate, and the floor surface is additionally decorated. deal with. The shortcoming of this technology is that the overall integrity of the floor is not strong, and the floor itself is not waterproof.

The Chinese patent of the patentee No. 200820133842.4 by the patentee has the following main advantages: (1) The template mesh used in the patented lightweight floor is a perforated plate, and the formed dental plate helps to strengthen the cement mortar layer and the template. The strength of the bond between the nets. With this type of perforated plate, it is possible to eliminate the need for steel bars, thereby reducing the amount of steel used and at the same time having good strength. (2) The thickness of the patented lightweight floor is generally 3-4 cm. Compared with the concrete slab currently used, the thickness is greatly reduced, so that the amount of concrete can be reduced, so that the lightweight slab of the utility model is lighter in weight.

However, this floor also has the following disadvantages.

First of all, the patent floor slab is not easy to be stepped and deformed due to insufficient bearing capacity of the reinforced expanded steel mesh during the construction process.

Secondly, the patent floor slab is easy to leak during construction, which brings trouble to the construction on site.

Third, the patent floor also has the drawback of being waterproof.

Finally, because the patent floor is subjected to negative moment force, the upper tension is borne by the steel mesh, but it cannot be positioned on the upper edge of the floor during construction, causing the bearing capacity to drop and causing cracks on the floor.

Some slabs for heavy-duty steel structures have also been disclosed in the prior art. These heavy-duty steel structures generally use floor slabs, shear pins and concrete cast-in-place slabs. Due to the different application areas of heavy-duty steel structure houses, the strength requirements for floor slabs are also different.
