Description

Technical Field

[0001] This utility model relates to the technical field of building construction, and in particular to a crack-preventing structure for newly built partition walls. Background Technology

[0002] Currently, when decorating interior partition walls, some use bricks, which involves a large amount of construction work, is labor-intensive and time-consuming, and produces a lot of dust that pollutes the construction site environment; others use light steel keel to assemble a frame on site, and then nail plasterboard to both sides. For example, the existing technology announcement CN107435397B proposes a prefabricated gypsum board partition wall, which includes several spliced ​​wall units. Each wall unit includes two layers of gypsum board, connectors, a first splicing component, and a second splicing component. The connectors are located between the two layers of gypsum board, connecting them. Both the first and second splicing components are long strips with a U-shaped cross-section. The web of the first splicing component has at least one insertion hole spaced along its length, and the web of the second splicing component has a locking protrusion corresponding to the insertion hole. The first and second splicing components are located on both sides of the wall unit and embedded between the two layers of gypsum board, serving as the vertical splicing surface of the wall unit. The second splicing component of the wall unit inserts into the insertion hole of the first splicing component of the adjacent wall unit to form a latch, locking the adjacent wall units horizontally and vertically. However, when using light steel keel gypsum board for newly built partition walls in home decoration, a wall-penetrating process is required. The partition wall and the original wall surface are made of two different materials. The shrinkage rate of the different materials at the contact point is different, which increases the chance of the putty cracking and affects the aesthetics later. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a new partition wall anti-cracking structure that can effectively prevent cracking and ensure the aesthetics of long-term use.

[0004] This utility model discloses a new type of anti-cracking structure for partition walls. The wall installation position has a connecting groove, and the partition wall panel is installed in the connecting groove. The gypsum board material overlaps the wall, and the contact surfaces of the gypsum board and the wall surface are staggered. By overlapping the gypsum board material with the original wall and staggering the contact surfaces of the base layer and the surface layer, cracking can be effectively prevented, ensuring the aesthetics of long-term use and reducing maintenance.

[0005] Preferably, the connecting groove is 1.5cm thick and 10cm wide, and is processed by removal; the 1.5cm thick and 10cm wide connecting groove can make the contact surface of the partition wall base layer and the contact surface of the wall surface layer staggered, which can effectively prevent cracking.

[0006] Preferably, the structural connection surface of the connecting groove is connected to the partition wall, and the joint between the partition wall surface and the wall surface layer is the seam; the partition wall and the wall are connected through the structural connection surface to form an overlap, and putty is applied to the seam later to effectively prevent cracking.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: by overlapping the gypsum board material with the original wall, the contact surface of the base layer and the contact surface of the surface layer are staggered, which can effectively prevent cracking, ensure the aesthetics of long-term use, and reduce maintenance.

[0013] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0014] like Figures 1 to 4 As shown, a connecting groove 2 is provided at the installation position of the wall 1. The connecting groove 2 is 1.5cm thick and 10cm wide. The partition wall panel is installed in the connecting groove 2 by removing and processing the partition wall panel. The gypsum board material overlaps the wall 1. The contact surfaces of the gypsum board and the surface layer of the wall 1 are staggered. The structural connecting surface 3 of the connecting groove 2 is connected to the partition wall. The joint 4 is where the partition wall surface and the surface layer of the wall 1 are spliced.

[0015] The 1.5cm thick and 10cm wide connecting groove 2 can offset the contact surface of the partition wall base layer from the contact surface of the wall 1, which can effectively prevent cracking. The partition wall and the wall 1 are connected by the structural connection surface 3 to form an overlap. Putty is then applied to the joint 4 to effectively prevent cracking.

[0016] like Figures 1 to 4 As shown, this utility model discloses a new type of anti-cracking structure for partition walls. During construction, a 1.5cm thick and 10cm wide connecting groove 2 is removed at the installation position. The partition wall and the wall 1 are connected by a structural connecting surface 3 to form an overlap. Putty is then applied to the joint 4. The contact surfaces of the base layer and the surface layer are staggered, which can effectively prevent cracking and ensure the aesthetics of long-term use.

[0017] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
