Description

Technical Field

[0001] This application relates to the field of waterproof structure technology, and more particularly to a TPO waterproof structure for steel structure roofs. Background Technology

[0002] Roof drainage is divided into organized drainage and unorganized drainage (free drainage). Organized drainage generally collects rainwater into gutters and then drains it through rainpipes. Gutters are the recessed sections between two spans of a steel structure roof, used to collect rainwater. Gutters are divided into internal gutters and external gutters. Internal gutters are those inside the exterior walls and usually have parapet walls, while external gutters protrude from the exterior walls and generally do not have parapet walls. Traditional steel structure roof gutters are prone to water accumulation and leakage. TPO waterproof membrane can be used to waterproof the gutters. TPO waterproof membrane is a new type of waterproof material widely used in the roofs of large industrial plants, public buildings, etc. TPO waterproof membrane is known for its excellent physical properties, environmental protection characteristics, and long-term weather resistance. The method of directly fixing TPO waterproof membrane to the bottom of the gutter with screws and sealing it with waterproof sealant can easily cause perforations in the waterproof membrane and the bottom of the gutter. With the help of wind and sun, the sealant at the screw holes is prone to aging and deformation, leading to water leakage at the screw locations. On-site repair is not only time-consuming and labor-intensive, but also affects the normal operation of production and safety. Utility Model Content

The fixing pipe is fixed to the steel structure roof. The first insulation board surrounds the edge of the fixing pipe. The second insulation board is laid on top of the first insulation board and the fixing pipe. The TPO waterproof membrane is laid on top of the second insulation board.

The sealing portion is connected to the TPO waterproof membrane by electromagnetic induction welding.

[0005] In some embodiments, the steel structure roof includes a gutter with a downpipe installed at the gutter. The downpipe passes through the first insulation board, the second insulation board, and the TPO waterproof membrane. The upper end of the downpipe extends out of the TPO waterproof membrane. A rainwater hopper is installed at the upper end of the downpipe. The lower end of the downpipe passes through the steel structure roof and is used to connect to a drainage pipe.

[0023] Figure 1 - Figure 3 This illustration shows an embodiment of the TPO waterproofing structure for a steel structure roof, including a fixing pipe 1, a first insulation board 2, a second insulation board 3, a TPO waterproofing membrane 4, and a non-perforated fastener 5. The fixing pipe 1 is fixed to the steel structure roof 10. The first insulation board 2 surrounds the edge of the fixing pipe 1. The second insulation board 3 is laid on top of the first insulation board 2 and the fixing pipe 1. The TPO waterproofing membrane 4 is laid on top of the second insulation board 3. The non-perforated fastener 5 includes a connecting part 51 and a sealing part 52. The connecting part 51 passes through the second insulation board 3 and is connected to the fixing pipe 1. The sealing part 52 is located on the underside of the TPO waterproofing membrane 4 and is coated with a TPO coating. The sealing part 52 is connected to the TPO waterproofing membrane 4 by electromagnetic induction welding.

[0024] In this application, the method of directly fixing the non-perforated fastener 5 to the bottom of the gutter 101 is eliminated. Instead, non-perforated electromagnetic induction welding is adopted, which ensures the waterproof effect and wind resistance of the waterproof joint of the gutter 101 and extends the service life of the gutter 101. It effectively solves the problem of water leakage caused by improper perforated welding or inadequate treatment of the weld joint in the waterproofing of the gutter 101. A fixing pipe 1 is set at the bottom of the gutter 101, so that the TPO waterproof membrane 4 laid on it can be directly welded to the non-perforated fastener 5 with TPO coating, which solves the problems of waterproofing safety and aesthetics of the gutter 101.

[0025] In some embodiments, the steel structure roof 10 includes a gutter 101, with a downpipe 6 installed at the gutter 101. The downpipe 6 passes through the first insulation board 2, the second insulation board 3, and the TPO waterproof membrane 4. The upper end of the downpipe 6 extends beyond the TPO waterproof membrane 4, and a rainwater hopper 7 is installed at the upper end of the downpipe 6. The lower end of the downpipe 6 passes through the steel structure roof 10 and is used to connect to a drain pipe. The installation of the downpipe 6 and rainwater hopper 7 at the gutter 101 allows accumulated water in the gutter 101 to flow from the rainwater hopper 7 into the downpipe 6, and then from the downpipe 6 into the drain pipe, from which the accumulated water is discharged.

[0026] In some embodiments, the TPO waterproof membrane 4 includes a first waterproof section 41 and a second waterproof section 42. The first waterproof section 41 is U-shaped and adapted to the shape of the gutter 101, while the second waterproof section 42 is laid on the plane of the steel structure roof 10. This ensures that the steel structure roof 10 has a good waterproof effect.

[0027] In some embodiments, the TPO waterproof membrane 4 is laid on the inner wall of the parapet wall 20 of the steel structure roof 10 and extends outward from the upper end of the parapet wall 20. This prevents rainwater from flowing into the gutter 101 from the inside of the parapet wall 20, and directs rainwater from the inside of the parapet wall 20 to flow from the upper surface of the TPO waterproof membrane 4 into the rainwater hopper 7, where the rainwater is drained out.

[0028] In some embodiments, a flashing 8 is provided at the upper end of the parapet wall 20, and the flashing 8 is located on the upper side of the TPO waterproof membrane 4. The flashing 8 can fix the TPO waterproof membrane 4 and also guide rainwater to the outside or inside of the parapet wall 20, facilitating the outflow of rainwater.

[0029] In some embodiments, the outer end of the flashing member 8 is higher than the inner end. This allows rainwater from the upper end of the parapet wall 20 to be directed to the inner side of the parapet wall 20, facilitating the drainage of rainwater from the rainwater hopper 7.

[0030] In some embodiments, purlins 201 extend from the inner wall of the parapet wall 20. The purlins 201 are connected to non-perforated fasteners 5, which are then connected to the TPO waterproof membrane 4 via electromagnetic induction welding. This ensures the firmness of the TPO waterproof membrane 4 on the inner side of the parapet wall 20 and improves the waterproofing effect.

[0031] In some embodiments, the fixing tube 1 is a square tube. This facilitates the fixing of the fixing tube 1 and also facilitates the connection with the non-perforated fastener 5.

[0032] In some embodiments, the upper surface of the first insulation board 2 is flush with the upper surface of the fixing pipe 1. This improves the flatness of the upper side of the steel structure roof 10 and extends its service life.

[0033] In some embodiments, multiple fixing pipes 1 are provided inside the gutter 101. The fixing pipes 1 are arranged along the length and width directions of the gutter 101, and non-perforated fasteners 5 are evenly distributed on the fixing pipes 1 at intervals of 400mm-600mm. This ensures the firmness of the connection between the non-perforated fasteners 5 and the fixing pipes 1.

[0034] Therefore, this application eliminates the method of directly fixing fasteners at the bottom of the gutter, and adopts non-perforated electromagnetic induction welding, which ensures the waterproof effect and wind resistance of the gutter waterproof joints and extends the service life of the gutter; it effectively solves the problem of water leakage caused by improper perforated welding or inadequate treatment of the weld joint; and the installation of a fixing pipe at the bottom of the gutter allows the TPO waterproof membrane laid on it to be directly welded to the non-perforated fasteners with TPO coating, solving the problems of waterproof safety and aesthetics of the gutter.

[0035] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
