Description

Technical Field

[0001] The utility model relates to the field of modular building related products, in particular to a gypsum board anti-cracking structure at a window. Background Art

[0002] Modular construction is an emerging building structure system that uses each room as a modular unit. All rooms are prefabricated in a factory, transported to the site, and assembled into a building through reliable connections.

[0003] During transportation, modular windows are prone to deformation due to uncontrollable factors such as natural and human factors, causing the windows and gypsum boards to be pressed against each other, which in turn causes the gypsum boards to crack. The window edging needs to be remade on site, which increases costs and cannot meet usage requirements. Utility Model Content

[0004] The purpose of the present invention is to provide a gypsum board anti-cracking structure at a window to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a gypsum board anti-cracking structure at the window, comprising a keel wall and a box steel structure, the keel wall being provided with an installation opening, the box steel structure being fixedly installed in the installation opening, an aluminum alloy window body being installed in the box steel structure, gypsum boards being provided on both sides of the box steel structure, the gypsum boards being fixedly connected to the keel wall and the box steel structure by a plurality of fixing nails, an edge strip being fixedly installed on the side wall of the gypsum board, a gap being provided between the edge strip and the aluminum alloy window body, and the gap being filled with sealant.

[0006] Preferably, the plurality of fixing screws are all dry wall screws.

[0007] Preferably, a gap of 10 mm is provided between the gypsum board and the aluminum alloy window body.

[0008] Preferably, the edge trimming strip is a Z-shaped edge trimming strip.

[0009] Preferably, the sealant is silicone sealant.

[0010] Preferably, the gypsum board has a thickness of 12 mm.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The gypsum board anti-cracking structure at the window is formed into a whole through the keel wall and the box steel structure for installing the aluminum alloy window body, and the strength of the window opening is guaranteed. The gypsum board edging is installed on the keel wall, and the edging strips are formed in the gap between the gypsum board and the aluminum alloy window body to form an expansion joint to prevent direct contact between the gypsum board and the aluminum alloy window body and reduce the risk of cracking of the gypsum board. The gap between the edging strip and the aluminum alloy window body is filled with sealant to ensure the tightness of the seal. The utility model can have an adjustment margin in the event of box deformation through the expansion joint treatment between the gypsum board edging and the window, thereby preventing direct squeezing of the window and the gypsum board, reducing the risk of breakage of the gypsum board edging, and meeting customer needs.
