Building board

Abstract

The invention provides a building board which is of a three-dimensional net rack structure. The building board comprises surface layers located on the surfaces of the two sides of the board, a middle sound insulation layer located between the surface layers, and light sandwich layers located in filling gaps between the surface layers and the middle sound insulation layer. The surface layers and the middle sound insulation layer are made of sound insulation materials or composite sound insulation materials. The light sandwich layer is made of sound absorption materials. The building board is characterized by further comprising keels located between the surface layers and the middle sound insulation layers and connected with the surface layers, and the keels and the middle sound insulation layer are integrally formed into the three-dimensional net rack structure, or the keels, the middle sound insulation layer and the surface layers are integrally formed into the three-dimensional net rack structure. The building board has excellent sound insulation performance, and meanwhile the building board has good thermal insulation performance and is firm in structure, simple, reasonable, light in weight, thin, convenient to install, simple in production and manufacturing process and low in cost.

Description

technical field [0001] The invention relates to a building board, in particular to a building board with a three-dimensional grid structure. Background technique [0002] Due to the improvement of people's living standards, people pay more attention to the quality of life, and the requirements for the acoustic environment of living, working and living are constantly improving. [0003] With the continuous advancement of China's urbanization process and the increase of population density, land resources have become more precious. Due to the continuous improvement of construction technology and the continuous development of building materials and construction technology, more and more multi-storey and high-rise buildings have been developed. A large number of buildings adopt reinforced concrete structures, and are developing towards high-rise buildings and large bays. With the development of building structures, a large number of lightweight wallboard materials are applied t...

Problems solved by technology

In this patent, although a light steel keel frame is used, since the keel frame is fixed between the surface layers, when the room temperature changes drastically, the shrinkage of the wallboard and the keel frame is inconsistent, which is likely to cause cracking of the wall

In addition, although the wallboard achieves the effect of sound insulation to a certain extent, the effect of sound insulation is not good, and it still cannot meet people's increasingly higher acoustic requirements.
