Description

Technical Field

[0001] This utility model relates to the technical field of building construction, and in particular to a detachable wall boundary node structure. Background Technology

[0002] In the field of modern construction, color steel rock wool sandwich wall panels are widely used due to their excellent thermal insulation, sound insulation, and fire resistance. Especially in scenarios requiring rapid assembly and flexible space partitioning, the design of removable wall panels is particularly important. However, the existing technology for removable wall boundary joints in color steel rock wool sandwich wall panels has some significant shortcomings.

[0003] Specifically, current practice typically involves securing removable wall panels to the wall boundary using exposed self-tapping screws. While this method is simple and direct, the self-tapping screws and the resulting gaps are directly exposed, affecting the overall aesthetics of the wall and potentially becoming leak points. To conceal these imperfections, existing technology employs adding decorative edge trim panels to the outside of the wall panels. These trim panels cover the self-tapping screws and gaps, and sealant is applied to their surface to further ensure a tight seal.

[0004] However, this approach is relatively complex, increasing construction difficulty and cost. Furthermore, the use of decorative edge trim panels causes protrusions on the wall surface, preventing the achievement of a smooth, clean appearance similar to aluminum curtain walls. In addition, the additional materials required for the decorative edge trim panels increase material consumption and resource waste. Summary of the Invention

[0005] To address the aforementioned problems with existing detachable wall boundary node methods, this paper aims to provide a simple and low-cost detachable wall boundary node structure.

[0006] The specific technical solution is as follows:

[0007] A detachable wall boundary node structure, comprising:

[0008] A thick rock wool sandwich panel includes a fixed part and a detachable part, with a panel seam formed between the fixed part and the detachable part;

[0009] Two corner pieces are provided inside the plate seam, wherein one corner piece is connected to the fixed part and the other corner piece is connected to the detachable part;

[0010] A purlin includes a protrusion and two mounting portions respectively disposed on both sides of the protrusion. The protrusion and the two mounting portions form a "U"-shaped structure. The protrusion extends from the inside of the board joint into the board joint and is detachably connected to the two corner pieces. One mounting portion is detachably connected to the inside of the fixed portion, and the other mounting portion is detachably connected to the inside of the detachable portion.

[0011] A sealant is used to fill the gap between the outside and inside of the joint.

[0012] As a further improvement and optimization of this solution, one of the mounting parts is connected to the fixed part by wall panel self-tapping screws, and the other mounting part is connected to the detachable part by rivets.

[0013] As a further improvement and optimization of this solution, the corner piece is connected to the fixed part / the detachable part by rivets.

[0014] As a further improvement and optimization of this solution, the two corner pieces are connected to the protrusion by self-tapping screws.

[0015] As a further improvement and optimization of this solution, foam strips are also filled in the gap between the two corner pieces.

[0016] As a further improvement and optimization of this solution, both the outer side of the fixed part and the outer side of the detachable part have color steel outer plates, and each color steel outer plate has a folded edge formed towards the inside of the plate seam at one end near the plate seam, and the two corner pieces are respectively connected to the two folded edges.

[0017] As a further improvement and optimization of this solution, the folded edge length is 35mm.

[0018] As a further improvement and optimization of this solution, the sum of the length of the folded edge and the length of the protrusion is equal to the depth of the board seam.

[0019] The positive effects of the above technical solution compared with the existing technology are:

[0020] (1) In this utility model, the connection between the fixed part and the detachable part is achieved by purlins and two corner pieces. Finally, the gap between the boards is sealed with sealant. The structure is simple, which not only reduces the construction difficulty and construction cost, but also eliminates the need for additional materials for decorative edge panels, thus avoiding the appearance of protrusions on the wall surface and achieving the flat and simple appearance of aluminum curtain walls.

[0021] (2) In this utility model, the rivets between the corner piece and the fixed part / the detachable part are hidden in the board seam, which further improves the flatness of the wall surface. Attached Figure Description
