Description

Technical Field

[0001] This utility model belongs to the field of spliced ​​roof technology, and more specifically, it relates to a waterproof structure for roof joints. Background Technology

[0002] Prefabricated modular houses are prefabricated houses that are constructed by making full use of the inherent strength of color steel sandwich wall panels and roof panels, and then connecting them with rivets, bolts and self-tapping screws. They can be reused, do not require interior decoration, and realize the concept of temporary construction that is aesthetically pleasing, quick and safe to construct.

[0003] Based on the above, the inventors have discovered the following problems: When splicing current interlocking roofs, in order to maintain waterproofing, the two wall panels are usually made to fit together as closely as possible. At present, the joints of the wall panels are mostly flat. During installation, even though they are fitted together, there are still small gaps at the joints. During the rainy season, rainwater will enter the joints along the edges, and some water will flow into the house.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a waterproof structure for roof joints in order to achieve a more practical purpose. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a waterproof structure for roof joints, which addresses the issue that the joints of currently used wall panels are mostly flat. During installation, even though they are glued together, there are still small gaps at the joints, allowing rainwater to enter the joints along the edges during the rainy season.

[0006] The purpose and function of this utility model's waterproof structure for roof joints are achieved through the following specific technical means:

[0007] A waterproof structure for roof joints includes a first wall panel and a second wall panel. Waterproof protrusions are provided on the upper parts of the first and second wall panels. A connecting platform is provided on the side of the waterproof protrusions on the upper parts of the first and second wall panels. An outer inclined surface is formed on the lower part of the connecting platform on the upper parts of the first and second wall panels. A waterproof groove is formed on the lower part of the first and second wall panels. A mating platform is provided on the side of the waterproof groove, and an inner inclined surface is formed on the lower part of the mating platform.

[0008] Furthermore, the inclination angle of the inner inclined surface and the inclination angle of the outer inclined surface are matched and are the same size, and the inner inclined surface and the outer inclined surface fit together.

[0009] Furthermore, the inner side of the waterproof groove is provided with an arc-shaped concave surface, and the upper part of the waterproof protrusion is provided with an arc-shaped convex surface. The arc-shaped convex surface and the arc-shaped concave surface are adapted to each other, and the arc-shaped convex surface is located inside the arc-shaped concave surface.

[0010] Furthermore, a first connecting hole is provided on the connecting platform, and a second connecting hole is provided through the first wall panel and the second wall panel located on the outer side of the docking platform.

[0011] Furthermore, the second connecting hole and the first connecting hole are the same size and their positions correspond to each other, and several through slots are formed between the first connecting hole and the second connecting hole.

[0012] Furthermore, a first filling area is formed in the middle of the first wall panel, and a second filling area is formed in the middle of the second wall panel.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, the outer and inner inclined surfaces fit together. If water flows into the connection along the bottom edge, the upward-facing outer inclined surface can prevent water from entering the interior of the connection. The waterproof protrusion and waterproof groove work together, and the height of the waterproof protrusion can further stop the water flow, improving the overall waterproof performance.

[0015] In this invention, when the first wall panel and the second wall panel are spliced ​​together, the arc-shaped convex surface and the arc-shaped concave surface cooperate with each other to facilitate the splicing of the first wall panel and the second wall panel. After the splicing is completed, the interior of the first filling area and the second filling area can be filled with heat insulation material or sound insulation material to achieve the purpose of heat insulation or sound insulation.
