Description

Technical Field

[0001] This utility model relates to the field of fireproof air duct assembly technology, and more specifically to a gap-filling gasket for panel assembly. Background Technology

[0002] In the field of building electromechanical systems, fireproof ducts are mainly used for the protection of basement smoke exhaust systems or combined smoke exhaust and ventilation systems, air conditioning and ventilation systems, and ducts passing through fire compartments. Fireproof ducts are pipes mainly installed on the supply and return air ducts of ventilation and air conditioning systems or mechanical smoke exhaust systems. Under normal working conditions, they can also have the function of supplying air. Usually, multiple panels are fixed on adjacent components to assemble the main body of the fireproof duct, and then multiple fireproof ducts are assembled into a pipeline. However, when assembling existing panels, the gaskets at the corners are not securely installed and are easy to loosen. Moreover, there are gaps at the intersection of the panels installed at the corners, which require workers to apply glue to fill the holes, affecting the assembly efficiency. Utility Model Content

[0003] To address the existing technical problems, this utility model provides a gap-filling shim for assembling sheet metal, which solves the problem of unstable assembly and easy loosening of shims at corners, and can cover the gaps at the intersection of installed strips, eliminating the need for workers to apply glue to fill holes and improving assembly efficiency.

[0004] The technical solution adopted by this utility model is as follows: A gap-filling shim for assembling sheet metal includes a first piece, a second piece, and a third piece that are integrally formed and connected in sequence. The upper endpoints of the first, second, and third pieces are connected to the lower endpoints of the first piece to form the first side of the second piece, and connected to the lower endpoints of the third piece to form the second side of the second piece, so that the second piece has a triangular structure. An angle A is formed between the first side and the second side, and an angle B is formed between the two sides of the first and third pieces that is opposite to the angle A. A hanging piece is provided that fits against the side of the angle B and extends outward.

[0005] In some embodiments, the first sheet body and the third sheet body have the same structure.

[0006] In some embodiments, the first sheet and the third sheet are polygonal structures.

[0007] In some embodiments, the first sheet and the third sheet are symmetrically disposed on both sides of the second sheet.

[0008] In some embodiments, the sum of included angle A and included angle B is 180 degrees.

[0009] In some embodiments, the first side and the second side are of the same length, so that the second piece is an isosceles triangle.

[0010] In some embodiments, the extension length of the hanger on the first sheet and the third sheet is the same.

[0011] In some embodiments, the upper end face of the hanging piece is at the same angle as the included angle B.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: When encountering a corner during the assembly of the panels, the first, second, and third panels can be directly attached to the outer side of the corner, and simultaneously fastened to the corner by a hanging piece. After wrapping with a strip, the positioning pad is fixed at the corner, which solves the problem of unstable assembly and easy loosening of the pad at the corner. In addition, the hanging piece can cover the gap at the intersection of the installed strips, eliminating the need for workers to apply glue to fill holes and improving assembly efficiency.

[0019] like Figure 1-2 As shown, this embodiment provides a gap-filling shim for assembling sheet metal, comprising a first sheet 1, a second sheet 2, and a third sheet 3 integrally formed and connected in sequence. The upper endpoints of the first sheet 1, the second sheet 2, and the third sheet 3 overlap and connect with the lower endpoint of the first sheet 1 to form the first side 4 of the second sheet 2, and connect with the lower endpoint of the third sheet 3 to form the second side 5 of the second sheet 2, so that the second sheet 2 has a triangular structure. The first side 4 and the second side 5 are set at an angle A, and the two sides of the first sheet 1 and the third sheet 3 form an angle B opposite to the angle A. A hanging piece 6 is provided that fits against the side of the angle B and extends outward. The upper end face of the hanging piece 6 has the same angle as the angle B, and the extension length of the hanging piece 6 on the first sheet 1 and the third sheet 3 is the same.

[0020] In this application, the first side 4 and the second side 5 are of the same length, so that the second piece 2 is an isosceles triangle, as shown below. Figure 2-8 As shown, angle A is 45 degrees and angle B is 135 degrees. This size is suitable for use at a 135-degree corner.

[0021] It is worth noting that the sum of angles A and B should be 180 degrees. Figure 6 As shown, both included angle A and included angle B can be 90 degrees. At the same time, the extension length, width and outward extension length of the hanging piece 6 at the joint of the first piece 1 and the third piece 3 are not limited, as long as they meet the usage requirements. The hanging piece 6 is integrally formed with the first piece 1, the second piece 2 and the third piece 3 by die casting, stamping or cutting and bending.

[0022] In another embodiment, the first piece 1 and the third piece 3 are polygons with the same structure and are symmetrically arranged on both sides of the second piece 2.

[0023] It is worth noting that the shapes of the first piece 1, the second piece 2, and the third piece 3 are not limited. From a cost-saving perspective, such as... Figure 2-8 As shown, the first piece 1, the second piece 2, and the third piece 3 can be made into any shape, and the shapes of the first piece 1 and the third piece 3 can be the same or different. In addition, the shape of the hanging piece 6 is not limited; it can be polygonal or arc-shaped.

[0024] When assembling panels at corners, the first panel 1, the second panel 2, and the third panel 3 are attached to the outer side of the corner and fastened to the corner using the hanging piece 6. Then, the panel is wrapped with strips to secure the filler shim at the corner. This design prevents the filler shim from easily loosening or falling off even without nails, solving the problem of unstable shim assembly and easy loosening at corners. When nailing is required to penetrate the outer L-strip and filler shim, securing them to the fireproof panel, the hanging piece 6 acts as a positioning element during nailing, eliminating the need for manual effort to hold the shim in place. The shim is also less prone to displacement. Furthermore, the hanging piece 6 can cover the gaps at the intersection of the installed strips, eliminating the need for workers to apply glue to fill holes, improving assembly efficiency, and enhancing the aesthetics while ensuring a tight seal. The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
