Sound-insulation and fireproof inner wall board

Abstract

The invention provides a sound-insulation and fireproof inner wall board. The sound-insulation and fireproof inner wall board comprises a body, wherein the body is composed of an upper sound-insulation cement layer, a light board and a lower sound-insulation cement layer which are spliced; the upper sound-insulation cement layer and the lower sound-insulation cement layer are internally provided with reinforced bars; the upper and lower surfaces of the body are coated with fireproof coatings respectively; and one side edge of the body is provided with a clamping tenon composed of a semicircular convex edge and a rectangular convex edge, and the other side edge of the body is provided with a rabbet composed of a semicircular groove and a rectangular notch. When the sound-insulation and fireproof inner wall board is mounted, the side face of the inner wall board is provided with the groove and the rectangular notch, so that the accuracy of mounting and positioning is guaranteed and the sound-insulation and fireproof inner wall board is convenient to detach; a joint is prevented from being cracked; the surface of the body is coated with a fireproof material, and the color and luster are the same as those of the ground; the sound-insulation and fireproof inner wall board is beautiful and has good fireproof performance; and the halogen element in the coatings can be used for effectively isolating a heat source and the sound-insulation and fireproof inner wall board is widely applied to the fields including buildings and the like.

Description

technical field [0001] The invention relates to an inner wall board, in particular to a sound-proof and fire-proof inner wall board. Background technique [0002] For a long time, my country has used heavy materials such as bricks, cement, etc. for housing construction. The disadvantages are troublesome construction and maintenance, heavy wall weight, limited floor height, and high cost. With the development of society and the continuous improvement of people's living standards, The demand for building materials is increasing day by day, which will inevitably lead to an increase in environmental pollution and a waste of a lot of resources. Now the building materials for houses should be developed in a light-weight direction. However, the existing light interior wall panels have the problems of poor sound insulation effect, inaccurate installation and positioning, easy cracking at the joints, inconvenient disassembly, and no fireproof coating.

[0002] For a long time, my country has used heavy materials such as bricks, cement, etc. for housing construction. The disadvantages are troublesome construction and maintenance, heavy wall weight, limited floor height, and high cost. With the development of society and the continuous improvement of people's living standards, The demand for building materials is increasing day by day, which will inevitably lead to an increase in environmental pollution and a waste of a lot of resources. Now housing building materials should be developed in a light direction.

However, the existing light-weight interior wall panels have poor sound insulation effect, inaccurate installation and positioning, easy cracking at the seams, inconvenient disassembly, and no fireproof coating.
