Description

Technical Field

[0001] This utility model relates to the field of steel structure roofing technology, specifically a detailed waterproof structure for a steel structure roofing skylight panel. Background Technology

[0002] With the rapid development of the modern construction industry, the requirements for waterproofing in the construction field are becoming increasingly stringent. Many steel structure factory buildings also have higher requirements for roof waterproofing. Relying on the self-drainage of the roof slope cannot meet the usage needs. Therefore, how to improve the waterproofing performance of the steel pressure plate on the roof of the factory building has become a top priority.

[0003] Existing steel structure roofs have the following main problems in terms of waterproofing: 1) Due to imperfections in the overall structure and connection design of the roof, such as a simple roof structure and a lack of other effective waterproof layer designs, the overall waterproofing effect of the roof is generally poor; 2) Steel structure roofs are generally equipped with skylight structures, but due to structural defects at the sides of the skylight structure (i.e., the connection between the skylight and the roof), such as poor sealing between roof structures, the presence of many protruding screws, and a lack of other effective waterproof layer designs, water seepage occurs at the skylight connection. Summary of the Invention

[0004] The purpose of this utility model is to solve the technical problems existing in the prior art and to provide a detailed waterproof structure for a steel structure roof skylight panel.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A detailed waterproof structure for a steel structure roof skylight includes I-beams, with C-shaped purlins installed between the I-beams. The C-shaped purlins are connected and fixed to the I-beams by connecting steel plates and high-strength bolts. A bottom profiled color steel plate is connected above the C-shaped purlins, and a top profiled color steel plate is connected above the bottom profiled color steel plate. Grade A rock wool board is filled between the bottom profiled color steel plate and the top profiled color steel plate. Vertical edge locking is provided at the ends of the bottom profiled color steel plate and the top profiled color steel plate. TPO waterproof membrane is laid on the surface of the top profiled color steel plate. A skylight is provided between the ends of adjacent top profiled color steel plates. The overlapping parts of the top profiled color steel plate, the TPO waterproof membrane, and the skylight are connected and fixed by metal strips and self-drilling screws. Covering strips are connected and connected at the positions of the metal strips and self-drilling screws.

[0006] In a preferred embodiment of this utility model, weather-resistant sealant is provided at the joint between the light-transmitting panel and the top profiled color steel plate.

[0007] In a preferred embodiment of this utility model, the long side of the TPO waterproof membrane is parallel to the long side of the top profiled color steel plate.

[0008] In a preferred embodiment of this utility model, the long sides of the TPO waterproof membrane are lapped together, and the short sides of the TPO waterproof membrane are butt-jointed.

[0009] In a preferred embodiment of this utility model, the overlap width between the TPO waterproof membranes is mm.

[0010] In a preferred embodiment of this utility model, the connecting steel plate is connected and fixed to the fixing steel plate by the high-strength bolts, and the fixing steel plate is fixed on the I-beam.

[0011] In a preferred embodiment of this utility model, the overlapping portion of the top profiled color steel plate, the TPO waterproof membrane and the light-transmitting plate are all ridge-shaped structures with upward protrusions, and the ridge-shaped structures of the three are stacked.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a detailed waterproof structure for a steel structure roof skylight panel. Compared with ordinary waterproof membranes, it adds TPO waterproof membrane. TPO waterproof membrane is a new type of waterproof membrane with excellent performance, environmental protection, no pollution, no toxicity, odorless, aging resistance, weather resistance, and durability, thus meeting people's diverse needs.

[0013] 2. This utility model provides a detailed waterproof structure for a steel structure roof skylight panel. By treating the joints of the skylight panel and reinforcing the waterproofing of the roof ridge, it is beneficial to increase the waterproof performance of the detailed nodes and reduce the building's operating costs.
