Description

Technical Field

[0001] This utility model belongs to the technical field of building waterproofing systems, specifically a horizontal drain outlet structure for flat roof waterproofing systems and a flat roof waterproofing system. Background Technology

[0002] As an important form of rainwater outlet, horizontal rainwater outlets play a drainage role in flat roof waterproofing systems. Their main function is to effectively collect and guide rainwater from the roof into the drainage pipe during the organized drainage process of the roof or floor, ensuring that rainwater dripping onto the roof can be guided to the side rainwater outlets in a timely and orderly manner for discharge, thereby maintaining the dryness and safety of the building structure.

[0003] In existing technology, patent CN215054655U discloses a horizontal drain outlet structure for a flat roof waterproofing system. The use of positioning nuts and bolts facilitates the installation and fixing of the bend, and also allows for easy disassembly and cleaning of its internal cavity. The through-hole design further enhances on-site operation and facilitates quick disassembly and cleaning. While this horizontal drain outlet structure improves installation convenience and maintenance efficiency, a significant problem remains in practical application: due to the long-term exposure of roofs to the open natural environment, their surfaces often accumulate large amounts of leaves, dust, and other debris, potentially forming stubborn dust clumps. Existing horizontal drain outlet structures do not provide an effective solution to this problem, causing these leaf and dust clumps to flow into the drain pipes along with rainwater. Over time, the continuous accumulation of this debris in the drain pipes can easily lead to severe blockages, affecting not only the normal operation of the drainage system but also potentially threatening the structural safety of the building. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a horizontal drain outlet structure and a flat roof waterproofing system, which can filter and clean debris in rainwater, thereby effectively preventing the occurrence of drain pipe blockage.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] According to a first aspect of this utility model, a horizontal drain outlet structure for a flat roof waterproofing system is provided, comprising a wall, a roof covering the top of the wall, a first filter screen being provided inside the top of the roof, an isolation trough frame being fixedly provided on one side of the roof, a second filter screen being provided inside the isolation trough frame, a water pipe being fixedly provided at the bottom end of the second filter screen, an insert plate being inserted into the groove along the edge of the roof, a baffle plate penetrating through the insert plate, a floating column being fixedly provided at the bottom end of the baffle plate, and a grid scraper being fixedly provided at the bottom end of the floating column, the first filter screen and the second filter screen being connected through the grid scraper.

[0007] In one possible implementation of the first aspect, a limiting ring is fitted around the outside of the water pipe, one end of the limiting ring is hinged to a retaining sleeve, and the other end of the limiting ring has a positioning head for fixing the retaining sleeve passing through it. A universal joint is fixedly installed at the middle position of the outer side of the limiting ring, and a sleeve is fitted around the universal ball of the universal joint. A support foot is fixedly installed at the other end of the sleeve, and the support foot is pressed against the outside of the wall.

[0008] In one possible implementation of the first aspect, a bolt passes through the interior of the positioning head, the bolt passing through the ferrule and being helically connected to the ferrule.

[0009] In one possible implementation of the first aspect, a spring is sleeved on the outer side of the universal joint, and the spring is located between the limiting ring and the sleeve.

[0010] In one possible implementation of the first aspect, a handle is rotatably provided at the top of the first filter screen, the handle being placed inside a notch in the roof.

[0011] In one possible implementation of the first aspect, a positioning long screw is passed through both sides of the insert plate, and the positioning long screw is helically connected to the roof.

[0012] In one possible implementation of the first aspect, a guide shaft is fixedly provided at the middle position of the baffle, and the guide shaft passes through the insert plate.

[0013] In one possible implementation of the first aspect, both the first filter screen and the second filter screen are plastic mesh.

[0014] In one possible implementation of the first aspect, the interior of the floating column is a cavity, and the floating column is made of a plastic tube.

[0015] According to a second aspect of the present invention, a flat roof waterproofing system is provided, comprising the aforementioned horizontal drain outlet structure for a flat roof waterproofing system.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] This utility model provides a horizontal drain outlet structure for a flat roof waterproofing system. Through a grid scraper, it effectively isolates and intercepts larger debris such as leaves floating in rainwater, separating leaves inside the first filter screen. This, combined with a second filter screen, further separates any remaining debris, reducing dust agglomeration and the entry of leaves into the drain pipes. This significantly improves rainwater guidance, thereby reducing the risk of drain pipe blockage and ensuring only clean rainwater enters the drain pipes. It fundamentally solves the problem of debris easily flowing into drain pipes with rainwater, causing blockages, and improves the drainage quality of the drainage system. Because it effectively reduces the amount of debris entering the drain pipes, drainage efficiency is improved. Even in severe weather conditions, it ensures that rainwater is guided promptly and orderly to the lateral drain outlets for discharge, thus maintaining the dryness and safety of the building structure, avoiding leakage and water accumulation caused by poor drainage, and extending the building's service life.

[0018] Furthermore, the limiting ring, in conjunction with the outer clamp, positions the water pipe to the outside. The universal joint and sleeve then press the support foot firmly against the outer wall to support the water pipe, thereby preventing excessive rainfall and buffering the impact of rainwater passing through the pipe, thus improving the stability of the water pipe mounted on the wall.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] like Figures 1 to 6As shown, this utility model provides a horizontal drain outlet structure for a flat roof waterproofing system, including a wall 1, a roof 2 at the top of the wall 1, a protruding edge layer on the roof 2, a first filter screen 3 embedded inside the top of the roof 2, the first filter screen 3 being concave to filter leaves and dust clumps in the rainwater, an isolation trough 4 fixedly installed on the left side of the roof 2, the isolation trough 4 having a trapezoidal groove inside and a through groove at the bottom, a second filter screen 5 installed inside the isolation trough 4, both the second filter screen 5 and the first filter screen 3 having filter grooves on their surfaces, the second filter screen 5 being 3cm higher than the isolation trough 4 to better separate some of the passing leaves, a water pipe 6 fixedly installed at the bottom of the second filter screen 5, the water pipe 6 passing through... Water pipes 6 are laid through the through groove of the isolation trough 4. Insert plates 7 are inserted into the groove of the edge of the roof 2. The top of the insert plate 7 has a horizontal groove. The groove of the edge of the roof 2 has a slot, which is matched with the groove to form a cross shape. The insert plate 7 is inserted into the slot for quick positioning. A baffle 8 runs through the inside of the insert plate 7 and moves up and down in the horizontal groove of the insert plate 7. The baffle 8 can better isolate leaves and dust clumps. A floating column 10 is fixedly installed at the bottom of the baffle 8. The floating column 10 floats on the rainwater surface and isolates the leaves on the upper layer of rainwater. A grid scraper 11 is fixedly installed at the bottom of the floating column 10. The grid scraper 11 structure is located in the rainwater. The first filter screen 3 and the second filter screen 5 are connected through the grid scraper 11. The grid scraper 11 forms an interception structure to intercept large debris.

[0030] In one possible implementation, a handle 13 is rotatably mounted on the top of the first filter screen 3 via a pivot, and the handle 13 is positioned inside a notch in the roof 2 to facilitate lifting the first filter screen 3. Preferably, both the first filter screen 3 and the second filter screen 5 are made of plastic mesh. The plastic mesh design of the first filter screen 3 and the second filter screen 5 can prevent rusting and reduce production costs.

[0031] In one possible implementation, positioning screws 12 are inserted through both sides of the insert plate 7. The positioning screws 12 rotate inside the insert plate 7 and are helically connected to the roof 2. Rotating the positioning screws 12 tightens the insert plate 7 into the groove of the roof 2.

[0032] In one possible implementation, a guide shaft 9 is fixedly installed at the center of the baffle 8, and the center of the top transverse groove of the insert plate 7 is circular, with the guide shaft 9 passing through the insert plate 7 to guide its movement. Preferably, the interior of the floating column 10 is hollow, and the material of the floating column 10 is a plastic tube, so that the floating column 10 floats above the rainwater, lifting the grid scraper 11 for better leaf separation.

[0033] In one possible implementation, a limiting ring 14 is fitted around the outside of the water pipe 6. The limiting ring 14 is a semi-circular ring. A retaining sleeve 15 is provided at one end of the limiting ring 14. The retaining sleeve 15 and the limiting ring 14 are connected by a rubber connecting strip. A positioning head 16 passes through the inside of the other end of the limiting ring 14. The retaining sleeve 15 is installed on the outside of the positioning head 16 for quick positioning. A universal shaft 18 is fixedly installed at the middle position of the outer side of the limiting ring 14. A sleeve 20 is fitted around the universal ball of the universal shaft 18. One end of the sleeve 20 is opened into a circular groove, and the circular groove is opened inward. A support leg 21 is fixedly installed at the other end of the sleeve 20, and the support leg 21 is pressed against the outside of the wall 1. The universal shaft 18 is installed inside the sleeve 20 to facilitate the installation of the limiting ring 14 by the operator.

[0034] In one possible implementation, a bolt 17 passes through the interior of the positioning head 16, the bolt 17 passes through the ferrule 15, and the bolt 17 and the ferrule 15 are spirally arranged. Tightening the bolt 17 provides a more stable connection between the positioning head 16 and the ferrule 15.

[0035] Preferably, a spring 19 is sleeved on the outer side of the universal joint 18, and the spring 19 is located between the limiting ring 14 and the sleeve 20. The spring 19 deforms and slides on the outer side of the universal joint 18, thus providing a buffering effect.

[0036] More specifically, the working process and principle of the horizontal drain outlet structure for a flat roof waterproofing system of this utility model are as follows: The worker installs the first filter screen 3 and the second filter screen 5 into the filter groove of the roof 2 and the trapezoidal groove of the isolation frame 4, respectively. The insert plate 7 is then quickly inserted into the slot of the groove. The grid scraper 11 is installed between the first filter screen 3 and the second filter screen 5. In rainy conditions, rainwater enters the interior of the first filter screen 3 due to the slope of the roof 2. The filter groove of the first filter screen 3 isolates leaves and dust clumps from the rainwater. After passing through the first filter screen 3, the rainwater undergoes secondary filtration through the grid scraper 11 before entering the interior of the isolation frame 4. The rainwater is filtered three times through the second filter screen 5 inside the isolation trough 4. The rainwater separates and stays between the isolation trough 4 and the second filter screen 5. The filtered rainwater is discharged through the water pipe 6, which can prevent leaves and dust in the rainwater from clumping into the water pipe 6 and clogging it. This keeps the water pipe 6 clear of rainwater for a long time. After a period of use, the staff needs to go to the roof 2 to clean the first filter screen 3 and the second filter screen 5 on the roof 2 to maintain the filtration efficiency of rainwater. At the same time, in the case of heavy rain, the floating column 10 floats to the water surface and lifts the baffle 8 and guide shaft 9 at the top of the floating column 10 out of the horizontal groove. The grid scraper 11 at the bottom of the floating column 10 is also lifted to separate the leaves on the water surface. When installing the water pipe 6, the limiting ring 14 is installed on the outside of the water pipe 6 through the clamp 15, and the connecting positioning head 16 is tightened with the bolt 17 to complete the fixation. The support leg 21 is pressed against the outer wall of the wall 1 for fixation. In the case of heavy rain, the impact of rainwater on the water pipe 6 will be buffered by the universal joint 18 connecting sleeve 20 on the outside of the limiting ring 14 and the deformation of the spring 19, so as to reduce the impact received by the water pipe 6 and avoid the water pipe 6 breaking due to excessive impact force.
