Non-load partition wall board for inner wall

Abstract

The invention relates to a building material and an artificial board and discloses a non-load partition wall board for an inner wall. The board comprises two layers of stack-up wood-wool structural slabs and a keel arranged between the two layers of wood-wool structural slabs and used for supporting the wood-wool structural slabs, multiple hollow cavities are formed between the wood-wool structural slabs and the keel; and the wood-wool structural slabs are made of wood wool or straw wires. The board provided by the invention has the advantages that the weight is light; the density is less than one quarter of that of gypsum or a gypsum strand board and a cemented strand board and less than half of that of a large oriented strand board; the board is fireproof, flame-resisting, waterproof, high in strength-weight ratio, quake-proof, soundproof and noise-eliminating; after being subjected to fireproof and waterproof treatment and other treatments, the wood-wool structural slabs achieve the fireproof performance above the B1 level and the waterproof performance meeting the national construction wall material requirements; the construction weight of an inner wall is greatly reduced; the quake-proof performance, fire-proof performance, water resistance, soundproof performance, noise-eliminating performance and other performances of the construction are enhanced; and the construction intensity and the material damage in use are reduced.

Description

technical field [0001] The invention relates to a building material and an artificial board, in particular to a non-load-bearing inner wall partition wall board. Background technique [0002] The existing indoor non-load-bearing inner wall partition materials mainly include the following types: (1) ordinary hollow bricks, which are heavy in weight, not good enough in toughness, and poor in seismic performance; (2) composite structures made of gypsum board or gypsum board, Its structural diagram is as figure 1 As shown, two layers of gypsum boards 1 are supported by a light steel or wooden keel 2 between the two layers of gypsum boards 1, and a hollow cavity is formed between the gypsum boards 1, and any material may not be filled in the cavity, or it may be Such as figure 1 The filled insulation and sound-absorbing material 3 shown, such as polyethylene terephthalate (polyethylene terephthalate, referred to as PET), has a large weight and insufficient toughness, so a reinf...

[0002] The existing indoor non-load-bearing inner wall partition materials mainly include the following types: (1) ordinary hollow bricks, which are heavy in weight, not good enough in toughness, and poor in seismic performance; (2) composite structures made of gypsum board or gypsum board, Its structural diagram is as figure 1 As shown, two layers of gypsum boards 1 are supported by a light steel or wooden keel 2 between the two layers of gypsum boards 1, and a hollow cavity is formed between the gypsum boards 1, and any material may not be filled in the cavity, or it may be like figure 1 The filled insulation and sound-absorbing material 3 shown, such as polyethylene terephthalate (polyethylene terephthalate, referred to as PET), has a large weight and insufficient toughness, so a reinforcement layer is required, and the bending strength is not high, and the water resistance is not high. ; (3) Composite structures made of cement fiberboard or cement particle board, the schematic diagram of which is as follows figure 2 As shown, two layers of cement board 4 are supported by light steel or wooden keel 2 between two layers of gypsum boards 1, cement board 4 is cement fiber board or cement particle board, and a hollow cavity is formed between cement board 4, and The cavity may not be filled with any material, or as figure 2 The thermal insulation and sound-absorbing material 3 shown in the figure has a large weight and low water resistance; (4) composite structures made of oriented large particle boards, the schematic diagram of which is as follows: image 3 As shown, light steel or wooden keel 2 is set between two layers of oriented particle boards 5 to support two layers of oriented particle boards 5. A hollow cavity is formed between the oriented large particle boards 5, and any material may not be filled in the cavity, or it may be as image 3 The insulation and sound-absorbing material 3 shown is filled, and a layer of isolation decorative layer 6 or hanging board is set on the outer surface of the two layers of oriented particle board 5 as an isolation decorative layer, which plays an aesthetic role while protecting the oriented large particle board 5. Its fire prevention, Waterproof, weather resistance and other performance is not good
