Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a drainage ditch node structure based on TPO membrane. Background Art

[0002] In architectural design, roof waterproofing is primarily achieved through rigid and flexible methods. Rigid waterproofing is susceptible to cracking and water seepage due to temperature fluctuations. Consequently, flexible waterproofing is gaining increasing popularity. Existing building roofs often utilize new waterproofing materials such as SBS waterproofing membranes, TPO waterproofing membranes, and self-healing waterproofing membranes, which offer excellent durability, ductility, and ease of construction.

[0003] At present, TPO waterproof membranes are usually laid in the drainage ditches of eaves. Since TPO waterproof membranes are exposed to the outside for a long time and are affected by the external environment, TPO waterproof membranes are prone to cracking, which leads to water seepage problems in the waterproof ditches. At the same time, after the waterproof membranes are cracked, they are prone to forming hollows under exposure to the sun, affecting drainage. Utility Model Content

[0026] Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings.

[0027] Throughout this specification, reference to the terms "certain embodiments," "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that a specific feature, structure, material, or characteristic described in conjunction with the embodiment or example is included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0028] The present application embodiment discloses a drainage ditch node structure based on TPO membrane, referring to Figure 1 and Figure 2 , including a wall structure, the wall structure includes a roof 1, the roof 1 is paved with a waterproof board 5, the waterproof board 5 is a thermoplastic polyolefin waterproof composite metal plate, a parapet 2 is provided at the edge of the roof 1, a drainage ditch 3 is provided between the roof 1 and the parapet 2, a strip 4 is provided below the ditch, and the bottom end of the drainage ditch 3 is fixed on the strip 4.

[0029] The inner wall of the gutter 3 is paved with a waterproof membrane 6 made of thermoplastic polyolefin (TPO) material, with one side of the waterproof membrane 6 coated with adhesive. A covering member 7 is crimped onto the waterproof membrane 6, comprising a covering plate 71 and a covering strip 72. The covering plate 71 is fitted against the inner wall of the gutter 3 and crimped onto the waterproof membrane 6. One side of the covering plate 71 is fixed to the waterproof board 5, and the other side of the covering plate 71 is fixed to the inner wall of the gutter 3 away from the roof 1. Compression strips 8 are fixed to the covering plate 71 at the inner corners on both sides of the gutter 3, and are fixed to the roof strip 4 by fasteners 13, which are screws. The covering strip 72 is positioned above the compression strip 8 and fixedly connected to the covering plate 71.

[0030] By laying the waterproof membrane 6 in the drainage ditch 3, and crimping the covering member 7 on the waterproof membrane 6, and fixing the covering plate 71 with the compression strip 8, the covering plate 71 can be pressed on the waterproof membrane 6, and the covering member 7 can apply pressure to the waterproof membrane 6, so that the waterproof membrane 6 and the drainage ditch 3 are more closely fitted and less likely to crack. At the same time, the covering member 7 protects the waterproof membrane 6, and prevents the waterproof membrane 6 from being damaged by external forces, thereby causing water seepage problems. Since using fasteners 13 to fix the compression strip 8 will destroy the integrity of the waterproof structure, a covering strip 72 is provided on the compression strip 8 to isolate rainwater, prevent the compression strip 8 from being corroded by moisture, and avoid water seepage problems.

[0031] The covering plate 71 includes a bottom plate 711 and side plates 712 vertically connected to opposite sides of the bottom plate 711. A first bend 721 and a second bend 722 are provided at each end of the covering strip 72. The first bend 721 is parallel to and fixed to the side plates 712, while the second bend 722 is parallel to and fixed to the bottom plate 711. The provision of the first bend 721 and the second bend 722 increases the contact area between the covering strip 72 and the covering plate 71, making the connection between the covering strip 72 and the covering plate 71 more stable. The covering strip 72 also acts as a reinforcing rib. The support provided by the covering strip 72 on the side plates 712 and the bottom plate 711 increases the structural strength of the covering plate 71, pressing the covering plate 71 against the waterproof membrane 6. Furthermore, the covering strips 72 on both sides give the gutter 3 a V-shaped cross-section, which helps to increase the drainage speed of the gutter 3.

[0032] Reference Figure 1 and Figure 3 The drainage ditch 3 is a steel structure gutter, which is easy to install, light in weight, reduces the bearing capacity of the wall, and has good waterproof performance. A fixing frame 9 is installed between the drainage ditch 3 and the parapet 2. The side of the drainage ditch 3 is fixed to the parapet 2 through the fixing frame 9. The side of the fixing frame 9 close to the drainage ditch 3 is fixedly connected with an extension plate 91. The connection between the drainage ditch 3 and the fixing frame 9 is filled with sealant 12 to prevent rainwater from seeping in.

[0033] A flashing plate 10 is installed on the inner side of the parapet 2 and above the fixing frame 9. By arranging the flashing plate 10, the scouring of rainwater can be effectively prevented, and a waterproof effect is played at the same time to avoid rainwater infiltration.

[0034] Reference Figure 1 and Figure 4The waterproof board 5 includes a crest portion 51 and a trough portion 52. The side of the covering plate 71 is connected to the trough portion 52. A sealing plate 73 is fixed at the connection between the covering plate 71 and the waterproof board 5 and at the position of the crest portion 51, which is used to seal the gap between the crest portion 51 and the covering plate 71. One side of the sealing plate 73 is connected to the crest portion 51, and the other end of the sealing plate 73 is connected to the covering plate 71.

[0035] The cover plate 71, the cover strip 72, and the sealing plate 73, as well as the waterproof plate 5, the cover plate 71, and the sealing plate 73, are all connected by hot air welding. Hot air welding does not damage the waterproof structure, ensuring the integrity of the waterproof structure. Hot air welding fuses the joints between the cover plate 71, the cover strip 72, and the sealing plate 73, and between the waterproof plate 5, the cover plate 71, and the sealing plate 73, into one, thereby improving the sealing performance.

[0036] The implementation principle of the drainage ditch node structure based on TPO membrane in the embodiment of the present application is as follows: during installation, the waterproof membrane 6 is first laid on the inner wall of the drainage ditch 3, and then a cover plate 71 is pressed onto the waterproof membrane 6. One side of the cover plate 71 is connected to the waterproof board 5 by hot air welding, and a sealing plate 73 is provided at the crest 51 of the waterproof board 5 to block the gap between the cover plate 71 and the waterproof board 5. The other side of the cover plate 71 is fixed to the drainage ditch 3 by a closing strip 11, and the waterproof board 5 is installed on the inner side of the parapet 2 and above the closing strip 11.
