Description

Technical Field

[0001] This utility model relates to the field of eaves gutter waterproofing technology, and in particular to a roof eaves gutter waterproofing structure. Background Technology

[0002] Roof gutters (eaves gutters) waterproofing is a crucial aspect of building maintenance. Their function is to ensure the smooth drainage of rainwater and prevent leaks that could damage walls or the structure. Gullies are constantly exposed to rainwater, ultraviolet radiation, and temperature fluctuations, making them prone to corrosion, cracking, and water seepage at joints. If not addressed promptly, this can lead to damp walls, mold, and even foundation problems. Common waterproofing methods include applying elastic waterproof coatings (such as polyurethane or acrylic) to form a seamless protective layer, suitable for repairing minor cracks; laying waterproof membranes (such as SBS modified bitumen or PVC), which have strong anti-aging properties and are suitable for areas with large temperature differences or prone to water accumulation; and for metal gutters, regular inspection of welds and application of anti-rust paint are necessary. During construction, the substrate must be thoroughly cleaned to ensure it is free of debris and standing water. Special attention should be paid to vulnerable areas such as joints and corners, and waterproof underlayment or drainage boards should be installed if necessary.

[0003] Waterproof membranes often require heating to melt and adhesive the membrane before being bonded to the inner wall of the gutter. Over time, this process inevitably leads to aging and cracking, resulting in decreased waterproofing effectiveness. Furthermore, removing the membrane for later maintenance is extremely difficult. The installation process also requires a lengthy time, making prefabrication and rapid installation impossible. Therefore, further improvements are needed. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 As shown, a roof gutter waterproofing structure is disclosed, including a gutter 1 with a drainage outlet 2 at the bottom. A waterproofing plate 3 is attached to the inner wall of the gutter 1. Flip plates 5 are fixed to the top of both ends of the waterproofing plate 3, and the flip plates 5 are integral with the waterproofing plate 3. The flip plates 5 are fixed to the upper surface of the gutter 1. Multiple support components 6 are horizontally fixed inside the waterproofing plate 3. Each support component 6 includes a screw 61 and an internally threaded tube 62. The internally threaded tube 62 is sleeved on the surface of the screw 61 and is rotatably connected to the screw 61 by threads. A first end plate 63 is fixed to the end of the screw 61 away from the internally threaded tube 62. A sleeve 64 is rotatably sleeved on the surface of the end of the internally threaded tube 62 away from the screw 61. A second end plate 65 is fixed to the end of the sleeve 64 away from the internally threaded tube 62. The first end plate 63 and the second end plate 65 are respectively attached to the two sides of the inner wall of the waterproofing plate 3.

[0024] In this embodiment, both the waterproof membrane 3 and the flap 5 are made of stainless steel and are bent into shape by molds in the factory. The shape of the waterproof membrane 3 is perfectly matched with the shape of the gutter 1. After the waterproof membrane 3 is placed inside the gutter 1, the waterproof membrane 3 can fit perfectly against the bottom wall and side wall of the gutter 1.

[0025] A drain pipe 4 is fixed near the drain outlet 2 on the waterproof membrane 3, and the drain pipe 4 is located inside the drain outlet 2.

[0026] The drain pipe 4 is fixed to the waterproof membrane 3 by welding, and the water entering the waterproof membrane 3 can be discharged along the drain pipe 4 and the drain outlet 2.

[0027] Both the bottom of gutter 1 and waterproofing board 3 are inclined towards the drain outlet 2.

[0028] By designing the bottom walls of the gutter 1 and the waterproofing membrane 3 to be inclined, rainwater inside the waterproofing membrane 3 can flow more easily to the drain outlet 2 side, resulting in better drainage.

[0029] Both sides of the top of the gutter 1 are provided with sinkholes 8. The flaps 5 at both ends of the top of the waterproof board 3 are located inside the two sinkholes 8 respectively. Several bolts 9 are fixed to the bottom wall of the sinkhole 8. The flaps 5 are provided with second through holes 10 for passing through the bolts 9. The surface of the bolts 9 is rotatably connected with a second nut 11.

[0030] In this embodiment, the height of the sinkhole 8 is greater than the thickness of the flap 5, ensuring that water on the surface of the gutter 1 can flow into the interior of the waterproof membrane 3. After the bolt 9 passes through the second through hole 10 on the flap 5, the second nut 11 is screwed onto the surface of the bolt 9, and the flap 5 is pressed and fixed by the second nut 11.

[0031] A sealing strip 12 is provided between the lower surface of the flap 5 and the inner bottom wall of the settling tank 8.

[0032] In this embodiment, the sealing strip 12 is a water-swellable rubber strip to prevent water from entering the bottom of the waterproof board 3 along the gap between the flap 5 and the sink 8.

[0033] Two first through holes 66 are provided on the first end plate 63. A positioning rod 7 is fixed on the inner side wall of the waterproof plate 3 and passes through the first through hole 66. A nut 67 is fixed on the surface of the internal threaded tube 62.

[0034] When the waterproof membrane 3 is supported and fixed by the support component 6, the positioning rod 7 is passed through the first through hole 66 on the first end plate 63. When the internal threaded tube 62 is screwed in later, the screw 61 and the first end plate 63 will not be able to rotate.

[0035] A first nut 68 is rotatably connected to the surface of the screw 61. After the internally threaded tube 62 rotates along the screw 61 to the designated position, the first nut 68 is then tightened to press against the internally threaded tube 62, thereby locking and fixing the internally threaded tube 62.

[0036] Working principle: During installation, the waterproof membrane 3 is placed directly into the gutter 1, and the flap 5 is inserted into the sink 8. At this time, the bolts 9 on the bottom wall of the sink 8 pass through the second through hole 10 on the flap 5. Then, the second nut 11 is screwed on the surface of the bolt 9, and the flap 5 is pressed and fixed by the second nut 11. Next, install the support assembly 6, and fit the first through hole 66 on the first end plate 63 onto the positioning rod 7 on the inner wall of the waterproof membrane 3. Then, rotate the nut 67 on the surface of the internal threaded tube 62 with a wrench, so that the internal threaded tube 62 moves along the surface of the screw 61, so that the second end plate 65 is in contact with the inner wall of the other side of the waterproof membrane 3. Since the sleeve 64 is rotatably connected to the internal threaded tube 62, when the second end plate 65 is in contact with the inner wall of the waterproof membrane 3, it will not affect the continued rotation of the internal threaded tube 62. Thus, the screw 61 and the internal threaded tube 62 are used to press the first end plate 63 and the second end plate 65 against the inner wall of the waterproof membrane 3 respectively. Finally, rotate the first nut 68 to squeeze the internal threaded tube 62, thereby further fixing the internal threaded tube 62.

[0037] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
