[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] It should be noted that waterproof membrane is mainly used for building walls, roofs, tunnels, roads, landfills, etc. It is a kind of flexible building material product that can be rolled into a roll to resist the leakage of external rainwater and groundwater. After the waterproof membrane is produced, the tensile strength test of the waterproof membrane will be completed by a tensile clamp. The cooperation between the support platform 1, two movable plates 3, two fixed plates 4, fixed assembly 5 and adjustment assembly 2 set above can realize the tensile strength test of the waterproof membrane.

[0024] The two fixing components 5 each include a screw rod 501, the screw rod 501 is movably installed inside the two fixing plates 4, the outer surfaces of the two screw rods 501 are threadedly connected with movable blocks 502, pressing plates 503 are slidably installed on the opposite sides of the two fixing plates 4, and U-shaped blocks 504 are fixedly installed at both ends of the two pressing plates 503.

[0025] Specifically, the two ends of the waterproof membrane are placed on the top of the two movable plates 3 respectively, and the two screw rods 501 are twisted at the same time. The twisting of the two screw rods 501 drives the pressing plate 503 to move down and contact the waterproof membrane through the movable block 502, and the waterproof membrane is fixed by the pressing plate 503.

[0026] Slide grooves are provided on the left and right sides of the two fixing plates 4 , and one end of the two sets of U-shaped blocks 504 extends into the inside of the slide grooves. The bottoms of the two pressing plates 503 are provided with anti-slip stripes.

[0027] Specifically, when the pressing plate 503 moves, the U-shaped blocks 504 on both sides will slide inside the slide groove respectively, so as to limit the pressing plate 503. In addition, anti-slip stripes are set at the bottom of the pressing plate 503 to increase the friction between the pressing plate 503 and the waterproof membrane, thereby ensuring better fixation of the waterproof membrane.

[0028] An adjustment component 2 is fixedly installed inside the support platform 1, and the adjustment component 2 includes a cavity 201. The cavity 201 is opened inside the support platform 1, and a servo motor 202 is fixedly installed on the front side of the support platform 1. A worm 203 extending into the cavity 201 is fixedly installed at the output shaft of the servo motor 202. Two bidirectional threaded rods 204 are rotatably installed inside the cavity 201. Worm wheels 205 are fixedly installed on the outer surfaces of the two bidirectional threaded rods 204. The outer surfaces of the two worm wheels 205 are meshed with the worm 203. The outer surfaces of the two bidirectional threaded rods 204 are threadedly connected to two bidirectional threaded blocks 206.

[0029] Specifically, driven by the servo motor 202, the meshing relationship between the worm 203 and the worm wheel 205 simultaneously drives the two bidirectional threaded rods 204 to rotate. The rotation of the two bidirectional threaded rods 204 drives the two movable plates 3 to move to opposite sides through the bidirectional threaded block 206, thereby performing tensile testing on the waterproof membrane.

[0030] The front side of the support platform 1 is provided with scale lines.

[0031] Specifically, by observing the moving position of the movable plate 3 through the scale lines, the pull rope strength of the waterproof coiled material can be known.

[0032] Four rectangular grooves are formed on the top outer surface of the support platform 1, and the bottoms of the two movable plates 3 are fixedly connected to the two bidirectional threaded blocks 206 via connecting rods, and the four connecting rods are slidably installed between the rectangular grooves.

[0033] Specifically, when the moving plate 3 moves, the two connecting rods at the bottom will be driven to slide inside the rectangular groove, and the connecting rods will play a connecting role between the moving plate 3 and the bidirectional threaded block 206.

[0034] When implementing, follow these steps:

[0035] 1) When in use, place the two ends of the waterproof coiled material on the top of the two movable plates 3 respectively;

[0036] 2) Then twist the two screw rods 501, and the twisting of the two screw rods 501 drives the pressing plate 503 to move downward through the movable block 502 to fix the waterproof membrane;

[0037] 3) Then, the two bidirectional threaded rods 204 are driven by the servo motor 202 to rotate, and the rotation of the two bidirectional threaded rods 204 drives the two moving plates 3 to move to opposite sides through the bidirectional threaded block 206;

[0038] 4) Finally, the waterproof coiled material is subjected to a tensile test. The rope strength of the waterproof coiled material can be obtained by observing the moving position of the movable plate 3 through the scale line.

[0039] In summary, the waterproof membrane tensile test fixture, by setting a fixing component 5, places the two ends of the waterproof membrane on the top of the two movable plates 3 respectively, and twists the two screw rods 501 at the same time. The twisting of the two screw rods 501 drives the pressing plate 503 to move down and contact the waterproof membrane through the movable block 502. The waterproof membrane is fixed by the pressing plate 503, which is convenient for clamping and fixing waterproof membranes of different thicknesses.

[0040] Furthermore, by setting up the adjustment component 2, the two bidirectional threaded rods 204 are driven to rotate simultaneously through the meshing relationship between the worm 203 and the worm wheel 205 under the drive of the servo motor 202. The rotation of the two bidirectional threaded rods 204 drives the two movable plates 3 to move to opposite sides through the bidirectional threaded block 206, thereby performing a tensile test on the waterproof membrane. By observing the moving position of the movable plate 3 through the scale line, the pull rope strength of the waterproof membrane can be obtained. The electric design can ensure that the conditions of each test are consistent, thereby improving the repeatability of the test results.
