Technical Field

[0001] This utility model relates to the field of building assembly technology, specifically to a universal profile for the internal and external corners of prefabricated wall panels. Background Technology

[0002] Inside and outside corners are part of building construction. Inside corners refer to recessed corners, such as the angle between the ceiling and the surrounding walls, while outside corners refer to protruding corners, such as the angle formed by two walls at a corner in a hallway. Significant errors in the inside and outside corners of walls are immediately noticeable, affecting the aesthetics of home decoration and causing difficulties in the installation and placement of cabinets, furniture, etc., resulting in wasted space.

[0003] In existing technologies, different profiles are required for the internal and external corners of prefabricated wall panel connections, resulting in a wide variety of components and increased production costs. Visible gaps are easily generated at the joints of adjacent panels, affecting the flatness and aesthetics of the wall surface. Additional sealing treatment is often required at the connection joints, increasing construction costs. Utility Model Content

[0004] The purpose of this utility model is to provide a universal profile for the inside and outside corners of prefabricated walls, which aims to solve the problem that in the prior art, different profiles are used for the inside and outside corners of prefabricated wall panel connections, which cannot be used interchangeably and leads to increased production costs.

[0005] To achieve the above objectives, this utility model provides a universal profile for the internal and external corners of prefabricated wall panels, comprising: a profile body, the profile body having an L-shaped cross-section, and both ends of the profile body having insertion grooves; the inner end face or the outer end face of the profile body being a vertical end face, and the inner end face or the outer end face of the profile body having a wave groove arranged along the height direction of the profile body; and a vertically connected decorative panel can be attached to the inner end face or the outer end face of the profile body.

[0018] The present invention will be described in detail below with reference to specific embodiments.

[0019] In this utility model, when directional terms appear, they are used to facilitate the description of this utility model and simplify the description, rather than indicating or implying that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this utility model.

[0020] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] like Figure 1 As shown, a universal profile for the inside and outside corners of a prefabricated wall panel includes a profile body 10. The profile body 10 has an L-shaped cross-section and both ends of the profile body 10 are provided with insertion grooves 11, which are used to cooperate with the insertion connectors and the connecting profiles on the wall panel to achieve a stable and seamless connection.

[0022] The inner or outer end face of the profile body 10 is a vertical end face. A wave groove 12 is provided on the inner or outer end face of the profile body 10 along the height direction of the profile body 10. A vertically connected decorative panel 13 can be attached to the inner or outer end face of the profile body 10.

[0023] The inner end face of the profile body 10 is installed at the inside corner of the wall 1, and the outer end face of the profile body 10 is installed at the outside corner of the wall 1. The surface of the corrugated groove 12 is bonded with an adhesive layer, which can be used to attach decorative panels 13 with a thickness of 6mm to 9mm.

[0024] In this embodiment, the profile body 10 includes two vertically connected first connecting plate 101 and second connecting plate 102. A through hole 105 is provided at the corner connection between the first connecting plate 101 and the second connecting plate 102, and insertion slots 11 are respectively provided at the ends of the first connecting plate 101 and the second connecting plate 102.

[0025] The first connecting plate 101 and the second connecting plate 102 are each provided with a first T-shaped groove 103 and a second T-shaped groove 104. The first T-shaped groove 103 is located near the through hole 105 and its opening direction is towards the outside of the profile body 10. The second T-shaped groove 104 is located between the slot and the first T-shaped groove 103 and its opening direction is towards the inside of the profile body 10.

[0026] In practical implementation, the first connecting plate 101 and the second connecting plate 102 are integral structures formed from aluminum alloy through a hot extrusion process. The cavity wall thickness of the profile body 10 is 1.2mm to 2.0mm.
