Description

Technical Field

[0001] This utility model relates to the field of profiled steel sheet technology, and in particular to a composite thermal insulation and waterproof roofing structure made of profiled steel sheet. Background Technology

[0002] Roofing systems were officially introduced to China in 1999 and began to be used in various projects. Due to their numerous significant advantages, single-layer roofing systems were quickly recognized and accepted by the domestic market and experienced rapid development, being widely used in projects such as stadiums, exhibition halls, airports, industrial plants, logistics centers, shopping malls, hospitals, and railway stations. Single-layer roofing systems are characterized by their light weight, quick construction, easy maintenance, long lifespan, and excellent long-term cost-effectiveness. However, they typically use insulation boards for thermal insulation, which have poor air permeability. Furthermore, the joints between adjacent roof structures are simply placed side-by-side, easily creating gaps that allow rainwater to seep in. Utility Model Content

[0003] The purpose of this invention is to provide a composite thermal insulation and waterproof roofing structure made of profiled steel sheets to solve the above-mentioned problems.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model discloses a composite thermal insulation and waterproof roof structure made of profiled steel sheet, including a support assembly and a waterproof and breathable assembly connected above the support assembly. The waterproof and breathable assembly includes a breathable plate connected to the support assembly. The breathable plate is wavy, with several breathable holes at the troughs of the wavy plate. A waterproof plate is connected to the crest of the wavy plate. One side of the waterproof plate is bent upward to form an insert, and the other side of the waterproof plate is bent upward to form a groove. Adjacent waterproof plates are joined together by the insert and the groove. A roof assembly is connected above the waterproof plate.

[0006] Furthermore, the support assembly includes two symmetrically arranged structural purlins, the tops of which are connected to the ventilated plate.

[0007] Furthermore, the structural purlins are U-shaped, and several mounting holes are provided at the bottom of the two structural purlins.

[0008] Furthermore, the breathable plate and the waterproof plate are connected by rivets.

[0009] Furthermore, the roof assembly includes a roof panel, and an insulation layer is provided between the roof panel and the waterproofing board, with the bottom of the insulation layer placed within the space formed by the upward bending of the waterproofing board.

[0010] Furthermore, the top and bottom surfaces of the insulation layer are respectively bonded to the bottom surface of the roof panel and the top surface of the waterproofing board.

[0011] Furthermore, the roof panel is wavy.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] This invention enhances the breathability of the air by setting a breathable plate. Gas can be discharged from between the breathable plate and the waterproof plate through the vent holes. Two adjacent waterproof plates can overlap by inserting a plug on one waterproof plate into the groove of the other waterproof plate. This not only improves the connection effect but also reduces the gap between the two, preventing water seepage. Attached Figure Description

[0020] like Figure 1-4 As shown, a profiled steel sheet composite thermal insulation and waterproof roof structure includes a support assembly and a waterproof and breathable assembly connected above the support assembly. The support assembly includes two symmetrically arranged structural purlins 6, the top of which is connected to the breathable plate 1. The structural purlins 6 are U-shaped, and several mounting holes are provided at the bottom of the two structural purlins 6.

[0021] The waterproof and breathable component includes a breathable plate 1 connected to the support component. The breathable plate 1 is wavy, with several breathable holes 2 at the troughs. A waterproof plate 3 is connected to the crest of the breathable plate 1, and the breathable plate 1 and the waterproof plate 3 are connected by rivets 7. One side of the waterproof plate 3 is bent upward to form an insert 4, and the other side of the waterproof plate 3 is bent upward to form a groove 5. Adjacent waterproof plates 3 are joined together by the insert 4 and the groove 5, which improves the connection effect and reduces the gap between them, preventing water seepage.
