Abstract
The utility model relates to a light compound internal wall board which is provided with a surface layer and a light core layer. The periphery in the surface layer of the board body is wrapped with glass fibre cloth. The light core layer is a polystyrene foam plastic board. The light core layer is arranged in the hollow cavity of the board body. The hollow cavity of the board body is provided with only one layer on the cross section of the board thickness, and tongue-and-grooves are arranged at both sides of the board body. The light compound internal wall board solves the technical problems that the existing light compound internal wall board has complicated conformation and bigger manufacturing difficulty. The raw material of the light compound internal wall board does not use the clay, which saves the cultivated land and energy source. The wall board has light weight, high strength, simple structure, easy manufacture and convenient installation with good quality. The light compound internal wall board can be made of the magnesite material with good sound insulation, heat insulation, thermal insulation, water prevention, and flame resistance performances. The board body is not easy to deform without poison, harm, pollution and radiation. The light compound internal wall board can be suitable for internal walls of various buildings.
Description
Technical field
The utility model relates to a kind of building unit, particularly a kind of light weight board.
Background technology
For avoiding a large amount of the arable land to be destroyed, loam brick is prohibited by the most of area of China.China's Tenth Five-year plan spells out: must greatly develop have high-strength, lightweight, energy-conservation, joint soil, sharp useless, environmental protection and multi-functional new composite materials for wall.Existing lightweight composite inner wall plate has multiple, and general wallboard has surface layer and therebetween heat insulation inner sandwich layer of double-layer heat insulation and upper, middle and lower cavity, and structure is comparatively complicated, and manufacture difficulty is bigger, and multi-layer cavity also is difficult for guaranteeing the quality of wallboard.
The utility model content
The purpose of this utility model provides a kind of lightweight composite inner wall plate, and it is comparatively complicated to solve existing lightweight composite inner wall plate structure, the technical problem that manufacture difficulty is bigger.
The technical solution of the utility model: this lightweight composite inner wall plate, plate body has surface layer and lightweight core layer, it is characterized in that: wrap up glass fabric around in the surface layer of plate body, its lightweight core layer is a polystyrol plastic foam plate, lightweight core layer places in the cavity of plate body, and the cavity of plate body has only one deck on the cross section of thickness of slab.
There is tongue and groove the both sides of above-mentioned plate body.
The cavity circumferential width of above-mentioned plate body is 2-4 centimetre.
The length of above-mentioned plate body is 200-300 centimetre.
The width of above-mentioned plate body is 60-90 centimetre.
Beneficial effect: the plate body of wallboard can adopt concrete or magnesite binding material to add straw powder, wood shavings or other string and make, lightweight core layer adopts polystyrol plastic foam plate, without clay, saves and ploughs, energy conservation meets national materials for wall innovation industrial policy.The wallboard high-strength light, the cavity of plate body has only one deck on the cross section of thickness of slab, simple in structure, and is easy to manufacture, easy for installation, can guarantee the wallboard quality.And this wallboard can adopt the magnesite material manufacturing, and sound insulation, heat insulation, insulation, waterproof, fire resistance are good, and plate body is not yielding, and is nontoxic, harmless, pollution-free, radiationless, applicable to various inner wall of building.
