Description

Technical Field

[0001] The utility model relates to the technical field of building connectors, in particular to a positive angle buckle and a negative angle buckle. Background Art

[0002] When doing building decoration, it is often necessary to fix the panels to the outer corners and inner corners of the wall respectively. The outer corner refers to the corner on the outside of the wall, also known as the external corner. It is the intersection of two adjacent walls, forming an outward convex angle at the corner. The outer corner usually appears on the outside of the building, such as the outer corner of the wall, the corner of the building, etc. The inner corner refers to the corner on the inside of the wall, also known as the inner corner. It is the intersection of two adjacent walls, forming an inward concave angle at the corner. The inner corner usually appears at the intersection of the walls inside the house, such as the inner corner of the room or the curved corner. If the existing prefabricated decoration panels want to be fixed to the wall, they usually need to be fixed with bolts, which is neither beautiful nor convenient, and will damage the panels and walls during later disassembly and assembly.

[0003] At the same time, the existing prefabricated decoration boards are usually customized with different specifications and sizes, and cannot be adjusted on the decoration site. If the existing card strips and card parts cannot match, the size of the board needs to be cut on site or returned to the factory for rework, which is easy to affect the construction period. The re-customized boards are not produced in the same batch and the materials may be changed to produce color differences. Utility Model Content
