Abstract

The utility model discloses a hypotenuse gypsum board, including the gypsum board, two at least limits on gypsum board upper portion all set the hypotenuse of leanin. The utility model discloses the design of hypotenuse for hypotenuse between board and the board meets and forms V word mouth form during the installation, presents the expansion joint with the V word form, can avoid because of the height drop between board and the board that the basic fossil fragments unevenness leads to, can effectual abundant filling expansion joint agent material, guarantees construction quality, guarantees decorative effect. The utility model discloses can effectual formation unified construction process and standard, need not artifical manual operation, also help having solved each managers' supervision leak, save man-hour to promote work efficiency.

Description

Bevel edge gypsum board

Technical Field

The invention relates to the field of building materials, in particular to a bevel edge gypsum board.

Background

The gypsum board is a material prepared by taking building gypsum as a main raw material. The building material has the advantages of light weight, high strength, small thickness, convenient processing, sound insulation, heat insulation, fire prevention and other good performances, and is one of the currently-developed novel light boards.

The gypsum board is applied in China for decades, the appearance of the gypsum board is straight edge till now, the straight edge has the defect that the telescopic joint mixture between boards cannot be filled fully in practical application, the contact surface of the joint mixture is too small and narrow, cracks are easy to generate between the boards after the surface coating of the gypsum board is finished, the engineering quality is affected, the decorative effect is damaged, and in addition, if the foundation keel has slight deviation and is not flat, the height difference between the board surface and the board surface is easy to cause, and the decorative effect and the quality cannot be accepted. As chinese utility model patent CN208934329U discloses a "gypsum board", "including a core layer (110) formed of gypsum material, characterized in that, this core layer (110) includes a first gypsum material layer (112) and at least one second gypsum material layer (114), wherein this first gypsum material layer (112) and this second gypsum material layer (114) form a laminated structure, and this first and second gypsum material layer (112, 114) have different colours", the gypsum board in this patent is a straight edge structure, the flexible joint compound material between board and board can't be filled, influence construction quality and decorative effect.

Disclosure of Invention

The invention aims to solve the technical problems that the expansion joint mixture between the plates cannot be filled fully and the construction quality and the decorative effect are influenced in the prior art, and provides the inclined-edge gypsum board which has the advantages that the inclined edges between the plates form the V-shaped opening during construction, the expansion joints are presented in the V-shaped manner, the expansion joint mixture between the plates can be effectively and fully filled, the construction quality is ensured, and the decorative effect is ensured.

A bevelled gypsum board comprising a gypsum board, at least two edges of the upper portion of the gypsum board each being provided with an inwardly sloping edge.

In one embodiment, the thickness of the gypsum board is greater than or equal to 9.5mm, and each bevel edge is cut according to the proportion of 1/2-1/3 of the thickness of the gypsum board.

The invention has the advantages and beneficial effects that:

1. the design of the bevel edge ensures that the bevel edges between the plates are connected to form a V-shaped opening during installation, the expansion joint is shown in a V shape, the height drop between the plates caused by the unevenness of the foundation keel can be avoided, the expansion joint agent can be effectively and fully filled, the construction quality is ensured, and the decorative effect is ensured.

2. The invention can effectively form a unified construction process and standard, does not need manual operation, also helps to solve the supervision loophole of each manager, saves working hours, and thus improves the working efficiency.

Detailed Description

In order to facilitate an understanding of the invention, a full description thereof will be given below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Example 1

Referring to fig. 1 to 3, a hypotenuse gypsum board comprises a gypsum board 1, and four sides of the upper part of the gypsum board 1 are provided with inwardly inclined hypotenuses 2.

The thickness of the gypsum board 1 is greater than or equal to 9.5mm, and each bevel edge 2 is cut according to the proportion of 1/2-1/3 of the thickness of the gypsum board 1 (namely, the thickness occupied by each bevel edge 2 is 1/2-1/3 of the thickness of the whole gypsum board 1).

It should be noted that: in other embodiments it is also possible that three edges of the upper part of the plasterboard 1 are provided as sloping edges 2, or that two edges of the upper part of the plasterboard 1 are provided as sloping edges 2.

The invention has the advantages and beneficial effects that:

1. the design of the bevel edge 2 ensures that the bevel edge 2 between the plates is connected to form a V-shaped opening as shown in figure 3 when the expansion joint is installed, the expansion joint is presented in a V-shaped manner, the height drop between the plates caused by the uneven foundation keel can be avoided, the expansion joint agent can be effectively and fully filled, the construction quality is ensured, and the decorative effect is ensured.

The above-mentioned embodiments only express one embodiment of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.

Claims

1. A bevelled gypsum board comprising a gypsum board having an upper portion, at least two edges of the gypsum board each being provided with an inwardly inclined bevelled edge;

the thickness of the gypsum board is greater than or equal to 9.5mm, and each bevel edge is formed by cutting according to the proportion of 1/2-1/3 of the thickness of the gypsum board.
