Description

Technical Field

[0001] This utility model relates to the field of waterproofing technology, and in particular to a composite waterproof membrane specifically designed for the roof slabs of underground buildings. Background Technology

[0002] The composite waterproof membrane for underground building roof slabs is a high-performance waterproof material with a multi-layer composite structure. It is specially designed for waterproofing underground engineering roof slabs and features high strength, puncture resistance, leakage resistance, and corrosion resistance. It is suitable for harsh environments that bear long-term loads, groundwater pressure, and environmental erosion.

[0003] Chinese Patent No. CN205476111 U discloses a composite waterproof membrane specifically for green roofs and underground building roofs. It comprises a seven-layer structure arranged sequentially from top to bottom: a PE release film layer, an SBS modified bitumen chemical root-barrier waterproof layer, a non-woven upper reinforcing layer, a high-molecular-weight polyethylene physical root-barrier waterproof layer, a non-woven lower reinforcing layer, a self-adhesive root-barrier bonding layer, and an aluminum foil release layer. The beneficial effects of this invention are: the addition of a self-adhesive root-barrier bonding layer improves the ease of construction of the SBS bitumen chemical root-barrier membrane; it increases the seamless adhesion between the membrane and the substrate; and it solves the problems of SBS bitumen chemical root-barrier membrane being easily damaged during cement slurry application and water seepage caused by uneven hot-melt application during hot-melt installation.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: when the existing composite waterproof membrane for underground building roofs leaks, it is not possible to quickly identify which area of ​​the membrane is leaking, which makes the repair process more complicated and the repair time too long. At the same time, it is not possible to effectively drain the water that falls on the membrane, which leads to a reduction in the effectiveness of the waterproof membrane after long-term use. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art that it is impossible to quickly detect leaks and effectively drain water that has fallen onto the waterproof membrane, and to propose a composite waterproof membrane specifically for the roof slab of underground buildings.

[0006] The technical solution of this utility model: a composite waterproof membrane for underground building roof slabs, comprising a drainage layer and a waterproof membrane layer disposed at the bottom of the drainage layer; further comprising:

[0007] The filtration and drainage mechanism is installed on the drainage layer and is used to filter the water that is guided to the center of the drainage layer and discharge the filtered water to the outside.

[0008] The testing agency is located at the bottom of the waterproof membrane layer and is used to divide the entire roll of membrane into sections and test the leakage of each section.

[0009] The waterproofing membrane layer includes a permeation board, which is placed at the bottom of the waterproofing membrane layer. A partition frame is installed on the outside of the permeation board, and the partition frame is made of waterproof material. The partition frame is used to divide the waterproofing membrane layer into individual areas. A detection board is installed at the bottom of the permeation board. The detection board is made of pH-sensitive material. When the waterproofing membrane layer fails, water leaks onto the permeation board, which then leaks water onto the detection board, causing the detection board to change color. Maintenance personnel can then inspect the waterproofing membrane layer in the area where the color changes.

[0010] Preferably, the filtration and drainage mechanism includes a drainage component and a mounting component;

[0011] The drainage system is installed on the drainage layer to guide water that falls on the drainage layer to the outside for discharge;

[0012] The mounting assembly is located on top of the drainage layer and is used to install the drainage assembly on the drainage layer.

[0013] Preferably, the drainage assembly includes a placement trough, a drainage channel, and a filter box;

[0014] The placement troughs are set on the drainage layer, and there are multiple placement troughs arranged vertically on the drainage layer. The drainage troughs are set on the side of the placement troughs, and there are two drainage troughs symmetrically arranged about the placement troughs. The filter box is snapped into the inside of the placement trough.

[0015] Preferably, the filter box has filter holes arranged in a ring.

[0016] Preferably, the mounting components include a mounting plate and a bayonet;

[0017] The bayonet is located on the side of the placement slot. The mounting plate is snapped onto the drainage layer. The inner side of the mounting plate is connected to the outer side of the filter box. A connecting piece is provided on the mounting plate. A telescopic rod is provided on the side of the connecting piece. A spring is provided on the outer side of the telescopic rod. A sliding block is provided at the end of the telescopic rod away from the connecting piece. A sealing plate is provided on the side of the sliding block.

[0018] Preferably, the testing mechanism includes a limiting plate, a fixing frame, and a connecting rod;

[0019] The limiting plate is set on the outside of the partition frame, and the limiting plate is located at the four corners of the partition frame. The fixing frame is set on the side of the partition frame. The connecting rod is slidably set on the fixing frame. The top of the connecting rod is provided with a pull block, the bottom of the connecting rod is provided with a pressure plate, and the outside of the connecting rod is provided with a spring.

[0020] Compared with the prior art, the present invention has the following beneficial technical effects:

[0021] 1. Through the setup of the detection mechanism, when the waterproof membrane layer leaks, water falls through the penetration layer onto the detection board for detection. The partition frame divides the waterproof membrane layer into blocks, so when a leak occurs in a certain area, the problem area can be quickly located. This avoids the difficulty in locating the problem due to the spread of leakage in traditional integral waterproof layers, and avoids blind excavation or material replacement in non-leaking areas, significantly reducing maintenance time and material consumption. The detection board can be quickly disassembled and installed by pulling the pressure plate, so that the used detection board can be quickly replaced without affecting the working time of the roof maintenance. Moreover, the operation steps are simple and easy to learn.

[0022] 2. Through the setting of the filtration and drainage mechanism, the filter box filters the water falling on the drainage layer and then collects the impurities in the filter box. The water is discharged through the drainage channel. This can quickly drain the water, avoid water erosion of the structure, eliminate the threat of freeze-thaw cycle, improve the durability of the structure, and at the same time prevent impurities from entering the drainage channel and affecting the drainage effect. The impurities are used for backfill soil or greening soil, realizing the resource utilization of waste. Attached Figure Description

[0029] Example 1

[0030] like Figures 1-3As shown, the present invention proposes a special composite waterproof membrane for underground building roof slabs, including a drainage layer 1, a waterproof board layer 2 set at the bottom of the drainage layer 1, a detection mechanism, a filtration and drainage mechanism, and a permeation board 402. The drainage layer 1 is provided with an inwardly inclined slope to guide the water falling on it to the center of the drainage layer 1.

[0031] The filtration and drainage mechanism is installed on the drainage layer 1 to filter the water guided to the center of the drainage layer 1 and discharge the filtered water to the outside.

[0032] The testing agency is located at the bottom of the waterproof membrane layer 2, and is used to divide the entire roll area and test the leakage of each area;

[0033] A permeation plate 402 is installed at the bottom of the waterproof layer 2. A partition frame 401 is installed on the outside of the permeation plate 402. The partition frame 401 is made of waterproof material and is used to divide the waterproof layer 2 into individual areas. A detection plate 404 is installed at the bottom of the permeation plate 402. The detection plate 404 is made of pH sensitive material. When the waterproof layer 2 fails to waterproof, water leaks onto the permeation plate 402. The permeation plate 402 then leaks water onto the detection plate 404, causing the detection plate 404 to change color. Maintenance personnel can then inspect the part of the waterproof layer 2 that has changed color.

[0034] The filtration and drainage mechanism includes a drainage component and an installation component. The drainage component is disposed on the drainage layer 1 and is used to guide water falling on the drainage layer 1 to the outside for discharge. The installation component is disposed on the top of the drainage layer 1 and is used to install the drainage component on the drainage layer 1. The drainage component includes a placement trough 301, a drainage channel 302, and a filter box 305. The placement trough 301 is disposed on the drainage layer 1, and multiple placement troughs 301 are arranged vertically on the drainage layer 1. The drainage channel 302 is disposed on the side of the placement trough 301, and two drainage channels 302 are symmetrically arranged about the placement trough 301. The filter box 305 is snapped into the inner side of the placement trough 301. The filter box 305 has filter holes arranged in a ring on it. Multiple filter boxes 305 are arranged at equal intervals on the drainage mechanism. The filter box 305 filters the incoming water, and the water is discharged through the drainage channel 302. Impurities are filtered out by the filter box 305 and collected inside. The mounting assembly includes a mounting plate 304 and a bayonet 303. The bayonet 303 is located on the side of the placement slot 301. The mounting plate 304 is snapped onto the drainage layer 1. The inner side of the mounting plate 304 is connected to the outer side of the filter box 305. A connecting piece is provided on the mounting plate 304. A telescopic rod 307 is provided on the side of the connecting piece. A second spring 308 is provided on the outer side of the telescopic rod 307. A sliding block 306 is provided at the end of the telescopic rod 307 away from the connecting piece. A sealing piece 309 is provided on the side of the sliding block 306. Pressing the sliding block 306 snaps the mounting plate 304 into the middle position of the drainage layer 1. Then, releasing the sliding block 306 causes it to snap into the bayonet 303 under the action of the second spring 308.

[0035] Example 2

[0036] like Figures 4-5 As shown, this utility model proposes a special composite waterproof membrane for underground building roof slabs. Compared with Embodiment 1, this embodiment details the structure of the testing mechanism.

[0037] The testing mechanism includes a limiting plate 403, a fixing frame 405, and a connecting rod 406. The limiting plate 403 is located on the outside of the partition frame 401, at the four corners of the partition frame 401. The fixing frame 405 is located on the side of the partition frame 401, and there are two fixing frames 405. The connecting rod 406 is slidably mounted on the fixing frame 405. A pull block 407 is provided at the top of the connecting rod 406, a pressure plate 409 is provided at the bottom of the connecting rod 406, and a pressure plate 409 is provided on the outside of the connecting rod 406. A spring 408 is used to pull a connecting rod 406 via a pull block 407. The connecting rod 406 causes the pressure plate 409 to rise, at which point the spring 408 is compressed, placing the test plate 404 on the permeation plate 402. The four corners of the test plate 404 are restricted by the limiting plate 403, thus ensuring that the test plate 404 and the permeation plate 402 are completely overlapped. After installation, the pull block 407 is released, and the pressure plate 409 presses down on the test plate 404 under the action of the spring 408, thus making the test plate 404 and the permeation plate 402 fit tightly together.

[0038] In summary, when using this utility model, align the sliding block 306 with the slot 303, then press the sliding block 306 to engage the mounting plate 304 in the middle of the drainage layer 1. Then release the sliding block 306, and the sliding block 306 will engage with the slot 303 under the action of the second spring 308, thus completing the installation of the filter box 305. Pull the connecting rod 406 by the pull block 407, and the connecting rod 406 will drive the pressure plate 409 to rise, placing the detection plate 404 on the permeation plate 402. The four corners of the detection plate 404 are restricted by the limiting plate 403. After installation, release the pull block 407, and the pressure plate 409 will press against the detection plate 404 under the action of the first spring 408. The detection plate 404 and the penetration plate 402 are tightly bonded together. When water falls onto the drainage layer 1, the drainage layer 1 guides the water to the center through the upper slope, allowing the water to flow into the filter box 305. The filter box 305 filters the water, and the water is discharged from the drainage layer 1 through the drainage channel 302. Impurities are filtered out by the filter box 305 and collected inside. When it is necessary to empty the impurities in the filter box 305, the mounting plate 304 is removed. When the waterproof layer 2 fails at a certain point, water falls onto the detection plate 404 through the penetration plate 402. After the detection plate 404 comes into contact with water, the pH material on it changes color, thus making the leak visible.

[0039] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
