A crack-resistant gypsum board

Abstract

The invention belongs to the technical field of building decoration materials, and specifically relates to a crack-resistant gypsum board, which includes a base plate, the side of the base plate facing the outside is provided with uniformly distributed arc-shaped grooves, and the inside of the base plate is provided with uniformly distributed cavities; Arc-shaped plates corresponding to the arc-shaped grooves are inserted between the adjacent arc-shaped grooves; the arc-shaped plates are used to strengthen the strength of the substrate; the side of the arc-shaped plates away from the substrate is covered with a baffle plate ; An I-shaped airbag is connected between the adjacent substrates; the outer surface of the airbag is bonded to the end face of the baffle, and the airbag is used to tightly connect the two adjacent substrates and simultaneously compress the baffle; Arrange the arc-shaped groove on the side of the substrate facing the outside, and then insert the arc-shaped plate into the arc-shaped groove, so that the adjacent arc-shaped grooves are connected by two arc-shaped plates. When the substrate is pre-bent as a whole, it can be Corresponding support reduces the bending range of the substrate, thereby enhancing the crack resistance of the substrate, thereby increasing the service life of the substrate.

Description

technical field [0001] The invention belongs to the technical field of building decoration materials, in particular to a crack-resistant gypsum board. Background technique [0002] At present, with the improvement of people's living standards, most family houses are decorated with gypsum boards. Gypsum board is a lightweight, fire-resistant building decoration material, mostly used for indoor ceilings. There are various plate and strip products on the market. Most of the existing gypsum is made of polyvinyl alcohol, glue and water mixed into paste gypsum. The gypsum material of these gypsum boards is a moisture-absorbing material, so in It is used in some indoor environments that generate water vapor and humidity. After a period of use, the gypsum board will loosen and fall off, which will damage the original shape and destroy the indoor beautification environment. [0003] Especially in some areas where there is a lot of mining, blasting is often required during mining, s...

Problems solved by technology

There are various plate and strip products on the market. Most of the existing gypsum is made of polyvinyl alcohol, glue and water mixed into paste gypsum. The gypsum material of these gypsum boards is a moisture-absorbing material, so in It is used in some indoor environments that generate moisture and humidity. After a period of use, the gypsum board will loosen and fall off, which will damage the original shape and destroy the indoor beautification environment.

[0003] Especially in some areas where there is a lot of mining, blasting is often required during mining, so severe vibrations will be generated, and the gypsum board itself is made of lightweight materials, which has poor crack resistance, and because of excessive mining, it is easy to Earthquakes and other natural disasters will cause damage to the decoration in the building. For this environment, it is necessary to develop a gypsum board with strong crack resistance; accordingly, the present invention proposes a crack-resistant gypsum board. plate
