Composite board

Abstract

The invention discloses a composite board. The composite board comprises a first board, a second board and a plurality of beams connected with the first board and the second board; the first board andthe second board are boards with corresponding characteristics respectively, and each comprise a base board, a stretching resistance layer and a compression resistance layer; the first board and thesecond board are oppositely arranged, the outer surface of the first board and the outer surface of the second board are parallelly arranged at the preset distance, and the stretching resistance layerof the first board and the stretching resistance layer of the second board are the same in preset stretching prestress. The composite board provided by the invention can be used for wall surface panel or decorative panel for a building module, and boards for other purposes.

Description

technical field [0001] The application relates to a composite board, especially a composite board with cement as the main material. Background technique [0002] With the continuous development of the construction industry and the continuous updating and transformation of building materials, the production methods of buildings are also undergoing great changes. Today, new buildings are moving towards assembly and modularization. However, the structural panels used in building modularization have limited the progress of building modularization due to their single variety, substandard performance, and unqualified fire prevention and waterproofing. [0003] At present, the common structural panels on the market are roughly divided into organic panels and inorganic panels. [0004] Organic boards include traditional wood fiber boards, particle boards, OSB boards, wood fiber boards, etc. Most of these organic boards are flammable, have poor fire performance, and have the probl...

Problems solved by technology

However, inorganic plates also have other problems, such as high material density, heavy board weight, micropores in the overall structure, lack of toughness, easy to break when affected by impact stress and shear stress, and low structural strength Moreover, the nail holding power is poor, and the single-quality board is prone to warping and deformation after being placed for a long time, and the production cost is high.

Furthermore, the magnesium oxychloride cement used in the glass magnesium slab is corrosive to reinforcing materials such as steel, and the brittleness will gradually increase after long-term use, and the structural strength will decrease
