Description

Technical Field

[0001] The utility model relates to a mirror-connected core-type alpha gypsum wallboard, belonging to the technical field of gypsum wallboards. Background Art

[0002] Walls play an important role in buildings. Traditional walls are made of a variety of materials, including soil, stone, brick, wood, etc. The choice of these materials is influenced by local natural resources and cultural traditions. Traditional walls can be divided into solid walls, hollow walls and combined walls according to their construction methods. Solid walls are integrally made walls without brick joints and plate joints. They have high overall strength and are suitable for partitions in earthquake-prone areas or large shopping malls. Hollow walls are made of some lightweight materials (such as aerated concrete blocks). They have the advantages of light volume, good sound insulation and good thermal insulation. They are often used for non-load-bearing partition walls and filling walls of frame structures. Combined walls combine the characteristics of solid walls and hollow walls to achieve the desired effect through the combination of different materials. Traditional walls can be divided into load-bearing walls and non-load-bearing walls according to their stress-bearing methods. Load-bearing walls are the main walls that bear the weight of the upper building, and have high requirements for the stability and load-bearing capacity of the wall. Non-load-bearing walls are mainly used to separate indoor spaces, and have relatively low requirements for load-bearing capacity. The existing wall processing needs to be installed during application, and the outer surface has low strength, poor toughness, and poor surface flatness. For the heavier structure of the solid wall, the sound insulation effect of the hollow wall is poor, and the joints between the boards are easy to loosen and cannot be connected as a whole. Therefore, it is very important to develop a mirror-connected α gypsum wallboard. Utility Model Content

[0003] The utility model aims at the deficiencies existing in the above-mentioned prior art and provides a mirror-surface core-connected α gypsum wallboard.

[0004] The technical solution of the utility model to solve the above technical problems is as follows:

[0005] A mirror-connected core-type alpha gypsum wallboard comprises a wallboard, wherein the wallboard comprises a core layer and a surface layer symmetrically arranged on the outer surface of the core layer, an anti-cracking layer is arranged between the surface layer and the core layer, the surface layer is an alpha gypsum surface, the core layer is a foaming layer, and the wallboard connection surface is provided with a groove for injection connection, and the groove relative to the connection surface is mirror-symmetrical.

[0006] Furthermore, the anti-cracking layer is a fiber anti-cracking net.

[0007] Furthermore, the groove shape is a mortise and tenon shape or an eccentric circle or other shapes whose inner diameter is larger than the groove opening spacing at the edge of the connection surface.

[0008] Furthermore, the grooves on the connecting surfaces of adjacent wall panels are butt-connected to form a core body.

[0009] Furthermore, α-gypsum slurry is poured into the core body.

[0010] Furthermore, the surface layer has a thickness of 3-10 mm.

[0011] Furthermore, the foaming layer includes foamed alpha gypsum or rock wool or a mixture of glass fiber and foamed alpha gypsum.

[0012] Compared with the prior art, the beneficial effects of the utility model are: the structure of the application is simple and easy to install and operate. The surface of the surface layer is smooth and delicate, like a mirror and effectively improves the flatness of the surface. Combined with the fiber anti-cracking net of the anti-cracking layer, the strength of the wall is higher and the toughness is improved at the same time; the core layer is a foaming layer, which can effectively reduce the overall weight of the wall and achieve the effect of sound absorption and sound insulation; gypsum itself is a cementitious material, and no glue needs to be added.

[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0021] like Figure 1-Figure 6As shown, a mirror-connected core-type α gypsum wallboard includes a wallboard, the wallboard includes a core layer 3 and a surface layer 1 symmetrically arranged on the outer surface of the core layer 3, an anti-cracking layer 2 is arranged between the surface layer 1 and the core layer 3, the surface layer 1 is an α gypsum surface, the core layer 3 is a foaming layer, and the wallboard connection surface is provided with a groove 4 for injection connection, which is mirror-symmetrical relative to the groove 4 of the connection surface. The foaming layer is a solid body or a non-solid body.

[0022] The anti-cracking layer 2 is a fiber anti-cracking net.

[0023] The groove 4 is in the shape of a mortise and tenon shape, an eccentric circle, or other shapes whose inner diameter is larger than the opening spacing of the groove 4 at the edge of the connection surface.

[0024] The grooves 4 on the connecting surfaces of adjacent wall panels are butt-connected to form a connecting core 5 .

[0025] The core body 5 is filled with alpha gypsum slurry.

[0026] The thickness of the surface layer 1 is 3-10 mm. The surface of the surface layer 1 is smooth and delicate, and the thickness can be reduced or increased as appropriate under the condition of ensuring strength, and the thickness can be greater than 10 mm without considering the overall weight.

[0027] The foaming layer includes foamed alpha gypsum or rock wool or a mixture of glass fiber and foamed alpha gypsum.

[0028] When in use, the adjacent wall panels to be connected are butted together, and then the adjacent wall panels to be connected are fixed, and the grooves 4 formed by the butt joints are poured into the connecting body 5. After the α gypsum slurry is solidified, the two adjacent wall panels are melted into one. Due to the form and structure of the connecting body 5, the two wall panels will not loosen after being pulled or dragged after being connected, and a tightly connected integrated wall can be formed; when the wall panel is connected to an existing wall, it is necessary to open a groove 4 in the connection part of the wall in advance. The shape of the groove 4 is a mortise and tenon shape or an eccentric circle or other shapes with an inner diameter greater than the spacing of the grooves 4 on the edge of the connection surface. After the connection, pouring is also performed to melt them into one. The surface layer 1 is made of α gypsum and a small amount of additives. The surface of the surface layer 1 is smooth and delicate, like a mirror, and there is no need to plaster or redecorate the surface, and the surface flatness is effectively improved. The anti-cracking layer 2 uses a fiber anti-cracking net, which makes the wall stronger and more resilient. The core layer 3 is a foaming layer, and the foaming layer adopts α semi-hydrated gypsum foam or foamed α gypsum or rock wool or a mixture of glass fiber and foamed α gypsum, which reduces the overall weight of the wall and can achieve the effect of sound absorption and sound insulation. The structure of the present application is simple and easy to install. The surface of the surface layer 1 is smooth and delicate, like a mirror. Combined with the fiber anti-cracking net of the anti-cracking layer 2, the strength of the wall is higher and the toughness is improved; the core layer 3 is a foaming layer, which can effectively reduce the overall weight of the wall and achieve the effect of sound absorption and sound insulation; gypsum itself is a cementitious material, and there is no need to add glue. It can also be poured layer by layer to save formwork and release agent, which is environmentally friendly and saves manufacturing processes. It ensures the quality of the wallboard while greatly improving production efficiency.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
