Description

Technical Field

[0001] This utility model relates to the field of roof drainage structures, and more particularly to a passive drainage structure applied to TPO roofs. Background Technology

[0002] With the application and development of steel structures and metal roofs in large factories and public buildings, the construction techniques for their supporting TPO flexible waterproofing systems have been continuously improved, and the construction processes have also been greatly enhanced. However, leakage has always been a difficult problem to overcome in the industry, especially in important detailed structural areas.

[0003] Such problems are particularly evident at the intersection of electromechanical installation and TPO. One prominent issue is at the gutter siphon rainwater inlet, where there are problems such as leakage prevention, cold bridging, fixed joints, and electrochemical corrosion that urgently need to be addressed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a passive drainage structure for TPO roofs. The siphon rainwater hopper of this utility model is fixed to the galvanized steel plate by welding the rainwater hopper support, avoiding the need to open holes in the original insulation layer to reserve the installation position of the rainwater hopper, and reducing damage to the gutter insulation layer and other structures. The utility model is fixed to the galvanized steel plate by welding the connecting support, which effectively reduces the welding length and improves construction efficiency compared to the original full welding of the bottom of the siphon rainwater hopper. It also greatly reduces the deformation of the gutter caused by welding, and improves the construction quality and the appearance of the finished product.

[0005] This utility model is achieved through the following technical solution:

[0006] A passive drainage structure for TPO roofing includes a strip-shaped drainage gutter and a siphon rainwater hopper. The drainage gutter has a trough-shaped longitudinal section and, from bottom to top, comprises a galvanized steel plate, a vapor barrier, an insulation layer, and a TPO roll. The drainage gutter has drainage through holes, and the siphon rainwater hopper is fixedly and sealed onto these holes. The siphon rainwater hopper, from bottom to top, comprises an assemblable rainwater hopper support, a rainwater hopper base, and a deflector body. The rainwater hopper support includes a fixedly connected flange plate and at least three sets of connecting supports. The upper end of each connecting support is fixedly connected to the lower end face of the flange plate, and the lower end of each connecting support is welded and fixedly connected to the galvanized steel plate. The connecting supports penetrate the vapor barrier, the insulation layer, and the TPO roll. The flange plate presses down against the TPO roll. The deflector body is sealed and fixedly connected to the rainwater hopper base and the rainwater hopper support by multiple sets of locking bolts.

[0007] As can be seen, in the above technical solution, the structure of this utility model can prevent cold bridging. The siphon rainwater hopper is welded and fixed to the galvanized steel plate through the rainwater hopper support, avoiding the need to open holes in the original insulation layer to reserve the installation position of the rainwater hopper, reducing damage to the gutter insulation layer and other structures, and ensuring the integrity of the insulation system. The structure of this utility model can prevent electrochemical corrosion and leakage. After the siphon rainwater hopper is welded to the galvanized steel plate of the gutter through the rainwater hopper support, it is then bolted to the main body of the guide cover through the rainwater hopper base. Furthermore, by setting sealing gaskets, cold bridging and electrochemical corrosion are prevented, eliminating the risk of leakage in the later stages. This utility model is fixed to the galvanized steel plate by welding the connecting support, which effectively reduces the welding length and improves construction efficiency compared to the original full welding of the bottom of the siphon rainwater hopper. It also greatly reduces the deformation of the gutter caused by welding, improving the construction quality and the appearance of the finished product.

[0008] According to the above technical solution, preferably, the cross section of the connecting support is a steel section.

[0009] It can be seen that in the above technical solutions, the connecting support components of the steel section have high resistance to deformation.

[0010] According to the above technical solution, preferably, the length of the connecting support is adjustable, and the connecting support includes a first support part and a second support part. The first support part is provided with a strip groove, and the second support part is provided with a plurality of adjusting bolts that are slidably connected to the strip groove of the first support part.

[0011] As can be seen, in the above technical solution, the length of the connecting support is adjustable, which facilitates fine-tuning of the height according to different construction positions to meet on-site construction needs. When in use, the staff can first slide and adjust the first support and the second support to the appropriate position, and then lock the first support and the second support by adjusting the bolts.

[0012] According to the above technical solution, preferably, a sealing gasket is provided between the rainwater hopper base and the flange plate.

[0013] As can be seen, in the above technical solution, the sealing gasket is used to enhance the sealing effect.

[0014] According to the above technical solution, preferably, the thickness of the galvanized steel sheet is 2.5-5mm.

[0015] According to the above technical solution, preferably, the vapor barrier membrane is a double-layered PE vapor barrier membrane, and the thickness of a single-layer PE vapor barrier membrane is 0.2-0.5mm.

[0016] According to the above technical solution, preferably, the insulation layer is a double-layered thick rock wool, and the thickness of a single layer of thick rock wool is 35-80mm.

[0017] According to the above technical solution, preferably, the thickness of the TPO roll is 1.5-4mm.

[0018] The beneficial effects of this utility model are:

[0019] (1) The structure of this utility model can achieve cold bridge prevention. The siphon rainwater hopper is welded and fixed to the galvanized steel plate through the rainwater hopper support, which avoids the need to open holes in the original insulation layer to reserve the installation position of the rainwater hopper, reduces the damage to the structure such as the gutter insulation layer, and ensures the integrity of the insulation system.

[0020] (2) The structure of this utility model can prevent electrochemical corrosion and leakage. The siphon rainwater bucket is welded to the galvanized steel plate of the gutter through the rainwater bucket support, and then bolted to the main body of the guide cover through the rainwater bucket base. In addition, by setting sealing gaskets, etc., cold bridge and electrochemical corrosion are prevented, and the leakage risk in the later stage is eliminated.

[0021] (3) This utility model is fixed by welding the connecting support to the galvanized steel plate. Compared with the original siphon rainwater hopper bottom full welding, it effectively reduces the welding length, improves construction efficiency, and greatly reduces the deformation of the gutter caused by welding, thus improving the construction quality and finished product appearance.

The longitudinal section of the drainage gutter 1 is a trough-shaped structure. From bottom to top, the drainage gutter 1 includes a galvanized steel plate, a vapor barrier membrane, an insulation layer, and TPO roll material. The drainage gutter 1 has drainage through holes.

[0030] The structural design of this invention prevents cold bridging. The siphon rainwater hopper 2 is welded and fixed to the galvanized steel plate via the rainwater hopper support 3, avoiding the need to drill holes in the original insulation layer to reserve the installation position of the rainwater hopper, reducing damage to the gutter insulation layer and other structures, and ensuring the integrity of the insulation system.

By setting sealing gaskets, cold bridging and electrochemical corrosion are prevented, eliminating the risk of leakage later. This invention is fixed to the galvanized steel plate by welding the connecting support 7. Compared with the original siphon rainwater hopper 2 with full welding at the bottom, this effectively reduces the welding length, improves construction efficiency, and greatly reduces gutter deformation caused by welding, improving construction quality and the appearance of the finished product.
