Description

Technical Field

[0001] This utility model relates to the field of prefabricated kitchens and bathrooms, and particularly to the wall panel corner splicing structure of prefabricated kitchens and bathrooms. Background Technology

[0002] The aluminum alloy prefabricated integrated kitchen and bathroom system utilizes the structural strength and precision of the aluminum profile frame to achieve rapid assembly and easy flexible customization to various sizes. It can also integrate various finishes and sandwich structure composite materials. It can be pre-embedded with pipelines and bonded with various traditional and new finishes such as ceramic tiles, natural stone, and sintered stone. It has core advantages such as low carbon and energy saving throughout the process, environmental protection, full product customization, reduced building load, zero leakage, zero hollowing, zero falling off, fast installation, convenient use, and good user experience.

[0003] In the existing aluminum alloy prefabricated kitchen and bathroom, the main problems to be solved in the assembly design are assembly accuracy, assembly precision, and waterproofing and aesthetics caused by assembly gaps. The wall panels of prefabricated kitchen and bathroom usually adopt factory prefabricated edge-sealing profiles to achieve modular splicing. The traditional external corner structure is assembled by two wall panels with edge-sealing profiles with splicing bevels. Although this process avoids on-site cutting of the wall panel body, it still has the following structural defects: (1) Lack of spatial tolerance: The building base wall surface generally has vertical deviation (±3mm / 2m) and local unevenness, while the rigid geometric structure of the edge-sealing profile requires strict spatial matching. When there is a difference between the actual installation space and the design size: the tenon and mortise of the two sets of profiles at the external corner will cause mechanical interference due to displacement deviation (such as the male tenon hitting the female groove sidewall). The cumulative error of the profile end in the three-dimensional direction will cause the splicing resistance to surge; (2) Dynamic stress concentration phenomenon: the forced correction operation (such as hammering, lever pressing) taken to eliminate interference during the installation process will produce two types of problems: local deformation and plastic deformation at the thin wall of the profile; (3) Stress freezing: the residual assembly stress makes the external corner a structural weak point, and the joint expands after long-term use; (4) Operation obstacles in narrow space: the external corner of the kitchen and bathroom is often located in the dense pipe area (such as the corner of the drainage riser), and the installation efficiency needs to be improved; (5) Loss of control of joint uniformity: since the decorative surface (such as tiles) is prefabricated on the wall panel, if adaptive adjustments are made during the assembly of the external corner, it will often lead to the joint at the external corner being inconsistent with the plane joint of the wall panel. Meanwhile, the lower joint at the external corner will expand due to gravity sinking or stress release, resulting in a visually deformed gap band, which violates the refined requirements of high-end prefabricated decoration.

[0004] Therefore, how to solve the assembly and splicing problem at the external corner is one of the urgent problems to be solved in the third-generation product. Utility Model Content

[0013] Furthermore, the first splicing body is a first buckle strip with a hook-shaped cross-section; the second splicing body is a second buckle strip with a hook-shaped cross-section.

[0020] This utility model has the following positive effects: (1) This utility model directly forms an external corner on the edge profile of a wall panel, which only needs to be spliced ​​with another wall panel to complete the splicing of the wall panel at the external corner. Because the external corner is directly formed by the profile, the space tolerance is improved; at the same time, since the decorative layer is prefabricated and installed on it, the splicing seam at the external corner is controllable and the top and bottom are neat and beautiful. At the same time, since the two wall panels spliced ​​at the external corner adopt normal wall panel flat splicing, the assembly difficulty is effectively reduced, and the interference problem is greatly improved.

[0021] (2) This utility model, through the positioning strip, can effectively ensure the joint between the first and second decorative layers during the prefabrication of the decorative layer, thus ensuring the aesthetics and uniformity of the joint. At the same time, the positioning strip can preserve a larger space for grout filling between the first and second decorative layers, effectively improving the waterproofing capability.

[0022] (3) The design of the begonia corner of this utility model makes it easier to do a grout seal between the first decorative layer and the second decorative layer.

[0023] (4) The second decorative layer in this utility model adopts a partition installation strip because it is considered that kitchen and bathroom spaces often use the external corner as the reference for space partition. The partition installation strip and the external corner extension form an embedded installation, which greatly simplifies the construction process of the partition and improves the assembly efficiency.

[0024] (5) The external corner splice seam formed between the partition installation strip and the first decorative layer in this utility model does not have the problems of assembly interference and space tolerance. At the same time, since the partition installation strip is generally made of aluminum alloy, the external corner splice seam is neat and beautiful.

[0025] (6) In this utility model, the first wall panel and the second wall panel are spliced ​​together by the first snap-fit ​​strip and the second snap-fit ​​strip. Due to the existence of the first adjustment groove and the second adjustment groove, while the first wall panel and the second wall panel are assembled with limiting on the inner and outer sides, they can also be adjusted to a certain extent in the width direction of the first adjustment groove and the second adjustment groove, thereby effectively controlling the splice seam between the third decorative layer and the second decorative layer. At the same time, since the adjustment direction is on the plane, the tolerance is strong and the adjustment is convenient.

[0026] (7) This utility model can effectively improve the flatness of the edge profile of the wall panel by using flat steel sheets and corner brackets, thereby improving the overall flatness of the wall panel. Attached Figure Description
