Description

Technical Field

[0001] The present invention relates to the technical field of wall leveling and installation, and particularly relates to a prefabricated wall base leveling system and an installation method thereof. Background Art

[0002] At present, the application of quick-install wall panels in the field of prefabricated decoration is becoming more and more popular. The existing installation method of prefabricated wall panels has certain flatness requirements for the original building wall. For uneven walls, leveling is still required. Currently, the leveling methods are mostly cement mortar, wooden squares, or installing a leveling keel on the original wall and then installing a base board, and then the surface quick-install board is directly bonded to the base board. The installation process is relatively complex. On the one hand, it prolongs the construction period, and on the other hand, it increases the work fatigue of construction workers. There are also cases where the wall is leveled by selecting a leveling structure to level the wall panels. However, in this leveling method, leveling bolts of different lengths need to be selected according to the wall flatness, and it is impossible to make one device suitable for multiple occasions. Different leveling bolts need to be replaced on walls with different flatness, wasting materials.

[0003] Chinese Patent CN113738052A, publication date December 3, 2021, discloses a prefabricated wall panel leveling structure, including prefabricated quick-install wall panels, and fixed flat connection strips are symmetrically arranged on the back of the prefabricated quick-install wall panels; in this prior art, leveling bolts of different lengths are selected according to the wall flatness, so that the leveling keel is fixed on the wall using the leveling bolts and fixed connection expansion bolts, and then the prefabricated quick-install wall panels are fixed through the fixed flat connection strips to achieve the purpose of installation. The entire installation process has no wet operation. The wall leveling method uses leveling parts to replace leveling methods such as cement mortar and wooden squares, and there is no need to make a base board. The structure is simple and stable, the installation speed is fast, the construction process is reduced to save costs, it can be quickly leveled and fixed, the labor input is reduced, the problem of flatness between boards can be solved to improve the overall flatness and aesthetics, it is convenient for maintenance and quick replacement, the wall is free of wet operation, the construction process does not use glue and does not contain formaldehyde, and it is healthy and environmentally friendly. In the above patent, leveling bolts of different lengths need to be selected according to the wall flatness, and it is impossible to make one device suitable for multiple occasions. Different leveling bolts need to be replaced on walls with different flatness, wasting materials. Summary of the Invention

[0032] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other arbitrarily.

[0033] Please refer to Figures 1 to 9 An assembled wall base leveling system according to an embodiment of the present invention includes a wall panel 1, a first keel 2, a keel clip 3, a back hanger 4, and a telescopic member 5 with an adjustable length.

By adjusting the length of the telescopic member 5, the distance between the first clamping plate 31 and the wall surface can be adjusted. One end of the back hanger 4 is connected to the wall panel 1, and the second card slot 44 is clamped to the second clamping plate 32.

[0034] Specifically, the first clamping plate 31 is slidably connected to the first card slot 23, so as to facilitate clamping the first clamping plate 31 at different positions in the first card slot 23, realizing sliding the keel clip 3 to different positions in the first keel 2. After one end of the telescopic member 5 is sequentially connected to the first clamping plate 31, the first keel 2 and fixed to the wall surface, and one end of the back hanger 4 is connected to the wall panel 1 and the second card slot 44 is clamped to the second clamping plate 32, the keel clip 3, the back hanger 4, and the wall panel 1 are sequentially connected together. When the positions of the first keel 2 and the wall panel 1 remain unchanged, by pre-adjusting the position of the keel clip 3 in the first keel 2, the position where the back hanger 4 is connected to the wall panel 1 can be adjusted. After the length of the telescopic member 5 is changed, the distance between different positions on the wall panel 1 and the wall surface can be adjusted, so as to realize leveling different positions on the wall panel 1.

[0035] The first keel 2 may include a first base plate 21 and two first stop plates 22 symmetrically connected to two side ends of the first base plate 21. The first card slot 23 is formed by the first stop plates 22 and the first base plate 21. There are two symmetrically arranged first card slots 23, and both ends of the first clamping plate 31 are clamped to the two first card slots 23 respectively.

The fastening nut 55 is screwed onto the part of the stud 531 on the side of the first base plate 21 when the limit block 532 abuts against the first clamping plate 31.

[0038] Specifically, the first installation through hole 211 is strip-shaped and the second installation through hole 311 is strip-shaped, which facilitates the movement of the first clamping plate 31 on the first base plate 21, so that the first preset position on the second installation through hole 311 is aligned with the second preset position on the first installation through hole 211. It can also include a gasket 54. The expansion tube 51 is fixedly connected to the wall surface. One end of the stud 531 sequentially passes through the second installation through hole 311 and the first installation through hole 211 and is then screwed to the first internal thread. The length of the stud 531 extending into the first internal thread is adjusted, thereby adjusting the overall length of the telescopic member 5. The gasket 54 is sleeved on the part of the stud 531 between the limit block 532 and the first clamping plate 31. The gasket 54 abuts against the first clamping plate 31, the limit block 532 abuts against the gasket 54, and the fastening nut 55 is screwed onto the part of the stud 531 on the side of the first base plate 21 to complete the installation.

[0053] An installation method of an assembled wall base leveling system includes the following steps:

[0054] S1: Slide the first clamping plate 31 on the keel clip 3 into the first clamping groove 23 on the first keel 2 to adjust the position of the keel clip 3 connected to the first keel 2.

[0055] S2: Connect one end of the telescopic member 5 to the first clamping plate 31 and the first keel 2 in sequence and fix it on the wall surface, and adjust the length of one telescopic member 5 to adjust the distance between the first clamping plate 31 and the wall surface.
