Gypsum board anti-crack structure and mounting process

Abstract

The invention discloses a gypsum board anti-crack structure and a mounting process. The gypsum board anti-crack structure comprises main keels and auxiliary keels which are installed on a ceiling andperpendicular to each other, the bottom faces of the auxiliary keels are connected with gypsum boards, the gypsum boards are fixedly connected with the main keels through gypsum board screws, the sideedges of the adjacent gypsum boards spliced by the gypsum boards are bevel edges, joints formed by splicing the gypsum boards and the adjacent gypsum boards are V-shaped joints, the V-shaped joints are located in the centers of the adjacent auxiliary keels and are connected through connecting gypsum boards, the contact faces of the connecting gypsum boards and the gypsum boards are fully coated with white latex, and the connecting gypsum boards and the gypsum boards are connected and fixed through long shooting nails. According to the gypsum board anti-crack structure and the mounting process, compared with the prior art, cracks on the gypsum boards can be effectively prevented, and the common problem of cracking of the joints of the gypsum board ceiling is well solved.

Description

technical field [0001] The invention relates to the technical field of building decoration, in particular to a gypsum board anti-crack structure and an installation process. Background technique [0002] Gypsum board is currently the most widely used new type of ceiling decoration material. It has good decorative effect and good sound absorption performance, and its price is lower than other roof decoration materials. The general practice and quality problems of traditional gypsum board installation are as follows: When suspending the ceiling, when the length and width of one gypsum board is exceeded, the gypsum boards must be spliced. The general method is to place the interface of two gypsum boards on the sub-keel of the light steel keel, and fix the gypsum board to the sub-keel with gypsum board screws Above; because the interface of two gypsum boards is fixed on the light steel keel sub keel, when the light steel keel material is affected by the temperature difference an...

[0002] Gypsum board is currently the most widely used new type of ceiling decoration material. It has good decorative effect and good sound absorption performance, and its price is lower than other roof decoration materials. The general practice and quality problems of traditional gypsum board installation are as follows: When suspending the ceiling, when the length and width of one piece of gypsum board is exceeded, the gypsum boards must be spliced. The general method is to place the interface of two gypsum boards on the auxiliary keel of the light steel keel, and fix the gypsum board to the auxiliary keel with gypsum board screws Above; because the interface of the two gypsum boards is fixed on the light steel keel auxiliary keel, when the material of the light steel keel is affected by the temperature difference and undergoes a physical reaction of thermal expansion and contraction, the gypsum board interface cracks; because the interface between the gypsum board and the gypsum board It is fixed on the auxiliary keel of the light steel keel, which is a hard connection, without crack resistance buffer, and is easy to crack. Although repeated repairs, cracking of the gypsum board cannot be avoided, which seriously affects the quality of the suspended ceiling
