Background Art

[0002] Self-adhesive waterproofing membrane is a waterproofing material made of self-adhesive rubber asphalt such as SBS, tackifier and high-quality petroleum asphalt as the base material, strong high-density polyethylene film or aluminum foil as the upper surface material, and a removable silicon-coated isolation film as the anti-adhesive isolation material on the lower surface. It has the characteristics of low-temperature flexibility, self-healing, and good bonding performance. No adhesive is required, and no heating and melting is required. Just tear off the isolation layer and it can be firmly bonded to the base layer. The construction is simple and fast. According to different base materials and shapes, self-adhesive waterproofing membranes form a continuous and closed waterproof layer through different construction schemes, and the seamless construction effect will have a good waterproof effect. The existing self-adhesive waterproofing membrane impermeability tests are all to test the impermeability of the membrane itself. There is no special test tool for the impermeability test at the corners and the overlap of the self-adhesive waterproofing membrane, which makes it difficult to test the impermeability of the self-adhesive waterproofing membrane at the corners and the overlap. Utility Model Content

[0016] The utility model provides a device for testing the anti-seepage performance of inner and outer corners and overlapping positions of self-adhesive waterproof membranes, and its beneficial effects are: the device for testing the anti-seepage performance of inner and outer corners and overlapping positions of self-adhesive waterproof membranes has a box body and a cylinder body, a inner corner can be formed inside the box body, and a outer corner can be formed outside the cylinder body. When in use, the self-adhesive waterproof membrane to be tested is adhered to the inner wall of the box body and the outer wall of the cylinder in a self-adhesive manner to form a continuous and complete waterproof layer, simulating the working conditions during actual construction. Since the device for testing the anti-seepage performance of inner and outer corners and overlapping positions of self-adhesive waterproof membranes provides inner corners and outer corners, only the inner corners and outer corners need to be tested during testing. Test papers should be set on the inner side of the inner corner, the outer side of the outer corner and the overlapping position of the self-adhesive waterproof membrane. The test papers are between the box body and the self-adhesive waterproof membrane or between the cylinder body and the self-adhesive waterproof membrane and are wrapped by the self-adhesive waterproof membrane. If test papers are set at the first detection position, the second detection position and the third detection position at the same time, the anti-seepage performance test of the inner corner, the outer corner and the overlapping position of the self-adhesive waterproof membrane can be carried out at the same time. During the test, a set amount of water is injected into the box body. The anti-seepage performance test can be achieved by observing the water immersion of the test papers at each position. If the test paper is not immersed in water, there is no leakage. If the test paper is immersed in water, leakage occurs.

[0022] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0023] like Figure 1 As shown, the utility model provides a device for testing the anti-seepage performance of the inner and outer corners and overlapping positions of a self-adhesive waterproof membrane, comprising:

[0024] The box body 1 is transparent, the top of the box body 1 is open, and the interior of the box body 1 forms a negative angle;

[0025] The cylinder 2 is transparent, the top of the cylinder 2 is open, the lower end of the cylinder 2 is sealed and connected to the bottom of the box body 1, and the outside of the cylinder 2 forms a positive angle;

[0026] The inner wall of the box body 1 and the outer wall of the cylinder body 2 are used to stick the self-adhesive waterproof membrane, and can form a first detection position and a second detection position at the inner corner and the outer corner respectively, and form a third detection position at the overlapping position of the self-adhesive waterproof membrane;

[0027] The test paper is arranged at at least one of the first detection position, the second detection position and the third detection position, and is wrapped by a self-adhesive waterproof coiled material.

[0028] Specifically, in order to solve the problem that there is no test tool for testing the anti-seepage performance of self-adhesive waterproof membrane at internal and external corners and overlapping positions in the prior art, the utility model provides a self-adhesive waterproof membrane internal and external corners and overlapping position anti-seepage performance testing device, which comprises a box body 1 and a cylinder body 2. A internal corner can be formed inside the box body 1, and a external corner can be formed outside the cylinder body 2. When in use, the self-adhesive waterproof membrane to be tested is attached to the inner wall of the box body 1 and the outer wall of the cylinder body 2 in a self-adhesive manner to form a continuous and complete waterproof layer, simulating the working conditions during actual construction. Since the self-adhesive waterproof membrane internal and external corners and overlapping position anti-seepage performance testing device provides internal and external corners, Therefore, during the test, it is only necessary to set the test paper on the inner side of the inner corner, the outer side of the outer corner and the overlapping position of the self-adhesive waterproof membrane. The test paper is between the box body 1 and the self-adhesive waterproof membrane or between the cylinder body 2 and the self-adhesive waterproof membrane, and is wrapped by the self-adhesive waterproof membrane. If the test paper is set at the first detection position, the second detection position and the third detection position at the same time, the anti-seepage performance test of the inner corner, the outer corner and the overlapping position of the self-adhesive waterproof membrane can be carried out at the same time. During the test, a set amount of water is injected into the box body 1, and the anti-seepage performance test can be achieved by observing the water immersion of the test paper at each position. If the test paper is not immersed in water, there is no leakage. If the test paper is immersed in water, leakage occurs.

[0029] Optionally, a weighing component 3 is further included, and the weighing component 3 is used to carry the box body 1.

[0030] Specifically, the weighing component 3 can carry the box body 1 so as to measure the amount of water injected into the box body 1 during the test. The amount of water is related to the test pressure, and the amount of water injected can be set according to the test pressure requirements.

[0031] Optionally, a drain port 4 is provided at a lower portion of one side wall of the box body 1 , and a blocking member 5 is provided on the drain port 4 .

[0032] Specifically, the provision of the waterproof opening can conveniently discharge the water in the box body 1 when the blocking member 5 is opened.

[0033] In this embodiment, the drain port 4 is a rectangular port, and the blocking member 5 cooperates therewith and can be made of rubber.

[0034] Optionally, the box body 1 and the barrel 2 are both made of acrylic.

[0035] Specifically, the box body 1 and the cylinder body 2 are both formed by sealing and bonding transparent acrylic plates, which is low in cost and easy to manufacture.

[0036] Optionally, the box body 1 is a rectangular box body 1 , and the cylinder body 2 is a rectangular cylinder body 2 .

[0037] Specifically, the connection position between the inner wall of the rectangular box body 1 and the bottom plate can form a negative angle that is consistent with the actual working condition, and the outer wall of the rectangular cylinder 2 can form a positive angle that is consistent with the actual working condition.

[0038] Optionally, the test paper is a medium-speed qualitative filter paper.

[0039] Specifically, medium-speed qualitative filter paper is used to improve its sensitivity to water, making it easier to observe and judge the anti-seepage performance.

[0040] Optionally, the weighing component 3 is an electronic scale.

[0041] Specifically, an electronic scale with a peeling function can be used as the weighing component 3, and water is injected into the box body 1 after peeling, which makes it easier to measure the amount of water injected.

[0042] Optionally, a pigment is also included, and the pigment is used to be placed in the box body 1.

[0043] Specifically, the pigment can be a color that has a significant contrast with the color of the self-adhesive waterproof membrane and the color of the medium-speed qualitative filter paper, such as green or blue, and can be placed in the box body 1 when water is injected into the box body 1 to facilitate observation of leakage.

[0044] In summary, when the anti-seepage performance testing device for the internal and external corners and overlapping positions of the self-adhesive waterproof membrane provided by the utility model is used, the anti-seepage performance of the internal and external corners and overlapping positions is tested simultaneously as an example:

[0045] 1. Paste the medium-speed qualitative filter paper at the first detection position at the inner corner, the second detection position at the outer corner, and the third detection position at the overlap of the preset self-adhesive waterproof membrane;

[0046] 2. Paste the self-adhesive waterproof membrane inside the box body 1 and outside the cylinder body 2, so that the overlap is aligned with the medium-speed qualitative filter paper pasted at the third detection position, and the self-adhesive waterproof membrane forms a continuous and complete waterproof layer inside the box body 1 and outside the cylinder body 2;

[0047] 3. Place the box body 1 on an electronic scale, operate the electronic scale to peel, pour a set amount of clean water according to the required pressure, and add an appropriate amount of pigment to the clean water for dyeing;

[0048] 4. As needed, maintain for a specific time at a temperature of (23±2)℃ and a relative humidity of (50±5)%, and observe through the transparent acrylic plate whether the medium-speed qualitative filter paper changes color. If color changes, it means that the anti-seepage performance of the self-adhesive waterproof membrane at the test location is poor. If there is no color change, it means that the anti-seepage performance test is successful and the anti-seepage performance of the self-adhesive waterproof membrane is qualified.

[0049] 5. After the experiment, open the sealing member 5, use a utility knife to cut the self-adhesive waterproof membrane along the square drain port 4, and release the water containing the pigment in the box body 1.

[0050] The various embodiments of the utility model have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
