Detailed Implementation
[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] like Figures 1 to 4As shown, an embodiment of the present invention provides a building waterproofing material testing fixture, comprising a fixing plate 1; a slot 12 is provided on the side wall of the fixing plate 1; a connecting plate 13 is detachably installed in the middle of the slot 12; a connecting rod 14 is fixedly connected to the side wall of the connecting plate 13; a slot 15 is provided in the middle of both the fixing plate 1 and the connecting plate 13; an elastic rope 16 is fixedly connected to the side wall of the connecting rod 14; an insert plate 17 is fixedly connected to the other end of the elastic rope 16; a clamping assembly is installed on the side wall of the connecting rod 14; during operation, the fixing plate 1 is installed on the testing device, and then the waterproofing material to be tested is clamped using the clamping assembly on the side wall of the connecting rod 14. The connecting plate 13 is then inserted into the slot 12 to connect the fixing plate 1 and the connecting rod 14. Finally, the insert plate 17 is pulled to insert it into the slot 15. The elastic rope 16 pulls on the insert plate 17 to prevent the fixing plate 1 and the connecting plate 13 from easily separating. Then, the testing device can be used to test the waterproof material. After completing the corresponding test on one testing device, the connecting rod 14 and the fixing plate 1 are separated by reverse operation. Then, the connecting rod 14 with the waterproof material is connected to the fixing plate 1 on another testing device. This way, the waterproof material being tested does not need to be repeatedly clamped and released. With the above structure, when multiple testing devices are needed to perform multiple tests on the waterproof material, the waterproof material does not need to be repeatedly clamped. The clamps and the waterproof material can be removed at the same time and installed on another testing device, reducing the impact of repeated clamping of the waterproof material on the physical properties of the waterproof material being tested.
[0025] like Figures 1 to 3 As shown, the clamping assembly includes a mounting rod 2; the mounting rod 2 is mounted on the side wall of the connecting rod 14; a support frame 21 is rotatably connected to the side wall of the mounting rod 2; a support plate 22 is fixedly connected to the top of the support frame 21; a pressure rod 23 is slidably connected to the side wall of the mounting rod 2; a pair of first fastening bolts 24 are rotatably connected to the middle of the pressure rod 23; the first fastening bolts 24 and the middle of the support plate 22 are threadedly engaged; during operation, when sampling and testing the waterproof material, some waterproof material will be cut off from the main body, and the edges of the cut waterproof material sample may not be smooth enough. The uneven edges of the waterproof material... The material passes between the support frame 21 and the mounting rod 2, positioning the center of the relatively intact waterproof material below the pressure rod 23. Then, the support plate 22 is rotated to the position below the pressure rod 23. Next, the first fastening bolt 24 is rotated so that its bottom end is screwed into the center of the support plate 22. By continuously rotating the first fastening bolt 24, the pressure rod 23 is moved towards the support plate 22, squeezing the waterproof material in the center to complete the clamping. With the above structure, the clamping position of the waterproof material can be easily adjusted, reducing the occurrence of insufficient clamping force due to uneven edges of the waterproof material, which could affect the testing.
[0026] like Figures 1 to 5As shown, the mounting rod 2 is rotatably connected to the side wall of the connecting rod 14; both ends of the mounting rod 2 are provided with insertion holes 3; a pair of through slots 31 are symmetrically arranged on the side of the mounting rod 2 facing the connecting rod 14; a sliding rod 32 is slidably connected to the middle of the connecting rod 14; a pair of insertion rods 33 are fixedly connected to the side wall of the sliding rod 32; during operation, after completing a test on the waterproof material, it is often necessary to observe the changes on the surface of the waterproof material. After observing one side of the waterproof material, the sliding rod 32 can be pulled to disengage the pair of insertion rods 33 from the inside of the insertion holes 3, and then the mounting rod 2 can be rotated to flip the waterproof material over. After flipping, the sliding rod 32 can be slid towards the inside of the connecting rod 14 so that the pair of insertion rods 33 are inserted into the inside of the insertion holes 3, so that the mounting rod 2 will not easily rotate again. With the above structure, the waterproof material can be flipped over without removing it, which is convenient for observing the waterproof material after testing and improves the ease of use of the device.
[0027] like Figures 1 to 3 As shown, the middle of the pressure rod 23 is threaded with multiple second fastening bolts 4; the bottom of the multiple second fastening bolts 4 is rotatably connected to a pressure plate 41; during operation, after the waterproof material is clamped by the bearing plate 22 and the pressure rod 23, the multiple second fastening bolts 4 are rotated to drive the pressure plate 41 to descend and squeeze the waterproof material, so that the waterproof material between a pair of first fastening bolts 24 can also be clamped and fixed more evenly, thereby reducing the occurrence of loosening of the waterproof material during testing. Through the above structure, the clamping force and clamping effect of the waterproof material can be improved, and the occurrence of loosening of the waterproof material affecting the testing can be reduced.
[0028] like Figure 5 As shown, one end of the slide rod 32 located inside the connecting rod 14 is fixedly connected to a spring 5; the other end of the spring 5 is fixedly connected to the inner wall of the spring 5. During operation, when the mounting rod 2 is flipped over and the slide rod 32 needs to be slid towards the inside of the connecting rod 14, the slide rod 32 can be released directly so that the slide rod 32 automatically slides into the inside of the connecting rod 14 under the pull of the spring 5. At the same time, during the test, the pull of the spring 5 on the slide rod 32 can reduce the occurrence of the slide rod 32 sliding off due to vibration. Through the above structure, the occurrence of the insertion rod 33 sliding out of the insertion hole 3 due to vibration can be reduced, thereby reducing the occurrence of the waterproof material rotating during the test.
[0029] like Figures 1 to 3As shown, multiple rollers 6 are rotatably connected to the middle of the support frame 21; the multiple rollers 6 are evenly distributed in the middle of the support frame 21; during operation, when it is necessary to clamp the waterproof material away from the edge, the edge of the waterproof material is passed through the gap between the support plate 22 and the mounting rod 2. In this process, the bottom of the waterproof material will come into contact and rub against the support plate 22. Through the setting of multiple rollers 6, the sliding friction between the waterproof material and the support plate 22 can be transformed into rolling friction, reducing the wear on the surface of the waterproof material being tested, and reducing the occurrence of obstruction when passing between the support plate 22 and the mounting rod 2 due to the unevenness of the waterproof material surface.
[0030] like Figure 2 As shown, multiple inclined plates 7 are fixedly connected to the middle of the mounting rod 2; the multiple inclined plates 7 are evenly distributed in the middle of the mounting rod 2; during operation, when the edge of the waterproof material is passed through the gap between the mounting rod 2 and the load-bearing plate 22, the inclined surfaces of the multiple inclined plates 7 will guide the edge of the waterproof material, so that the edge of the waterproof material can pass through the gap between the mounting rod 2 and the load-bearing plate 22 more smoothly. Through the above structure, when the waterproof material is clamped, the situation where the edge of the waterproof material abuts against the side wall of the mounting rod 2, causing connection inconvenience, can be reduced.
[0031] During operation, the fixing plate 1 is installed on the testing device. Then, the clamping assembly on the side wall of the connecting rod 14 is used to clamp the waterproof material to be tested. Next, the connecting plate 13 is inserted into the slot 12, connecting the fixing plate 1 and the connecting rod 14. Then, the insert plate 17 is pulled to insert into the slot 15. The elastic rope 16 pulls on the insert plate 17 to prevent the fixing plate 1 and the connecting plate 13 from easily separating. The testing device can then be used to test the waterproof material. After completing the corresponding test on one testing device, the connecting rod 14 and the fixing plate 1 are separated by reversing the operation. Then, the connecting rod 14 with the waterproof material is connected to the fixing plate 1 on another testing device, thus allowing the tested waterproof material to be tested. Repeated clamping and loosening is unnecessary. When sampling and testing waterproofing materials, a portion of the material is cut from the main body. The edges of the cut-off sample may not be perfectly smooth. The uneven edge of the waterproofing material is passed between the support frame 21 and the mounting rod 2, so that the center of the relatively intact waterproofing material is below the pressure rod 23. Then, the support plate 22 is rotated to be below the pressure rod 23, and the first fastening bolt 24 is rotated so that its bottom end is screwed into the center of the support plate 22. By continuously rotating the first fastening bolt 24, the pressure rod 23 is moved towards the support plate 22, squeezing the waterproofing material in the center to complete the clamping. After completing one test on the waterproofing material, it is often necessary to observe the changes on the surface of the waterproofing material. After one side of the material has been observed, the sliding rod 32 can be pulled to disengage the pair of insert rods 33 from the insertion holes 3. Then, the mounting rod 2 is rotated to flip the waterproof material over. After flipping, the sliding rod 32 is slid towards the connecting rod 14, allowing the pair of insert rods 33 to be inserted into the insertion holes 3. This prevents the mounting rod 2 from rotating easily. After the waterproof material is clamped by the bearing plate 22 and the pressure rod 23, the multiple second fastening bolts 4 are rotated to lower the pressure plate 41 and compress the waterproof material. This ensures that the waterproof material between the pair of first fastening bolts 24 is also clamped and fixed more evenly, thus reducing the occurrence of loosening of the waterproof material during testing. After completing the observation of the other side of the mounting rod 2, the sliding rod 32 needs to be slid towards the connecting rod 14. During internal sliding, the slide rod 32 can be released directly, allowing it to automatically slide into the connecting rod 14 under the pull of the spring 5. Simultaneously, during testing, the pull of the spring 5 on the slide rod 32 reduces the possibility of it sliding off due to vibration. When clamping the waterproof material away from the edge, the edge of the waterproof material is passed through the gap between the support plate 22 and the mounting rod 2. During this process, the bottom of the waterproof material will contact and rub against the support plate 22. The multiple rollers 6 transform the sliding friction between the waterproof material and the support plate 22 into rolling friction. When the edge of the waterproof material is passed through the gap between the mounting rod 2 and the support plate 22, the inclined surfaces of the multiple inclined plates 7 guide the edge of the waterproof material.This allows the edge of the waterproof material to pass more smoothly through the gap between the mounting rod 2 and the load-bearing plate 22.
