[0002] In building waterproofing engineering, the quality of waterproofing membrane directly affects the waterproof effect and service life of the building, and accurate determination of the tensile property of waterproofing membrane is crucial; in practical application, waterproofing membrane tensile property detection usually needs the following technologies:

[0003] 1. Firm clamping parts, such as high-strength metal clamping jaws, can tightly clamp waterproofing membrane to prevent slipping during stretching;

[0004] 2. Precise alignment device, such as adjustable positioning rod, ensures uniform stress of waterproofing membrane during tensile test, and guarantees the accuracy of test results;

[0005] 3. Reasonable tensile structure, such as smooth and effective electric or hydraulic stretching system, can uniformly and continuously apply tension to waterproofing membrane.

[0006] The existing waterproofing membrane tensile property detection fixture usually installs waterproofing membrane on the fixture first, and then performs tensile test, and usually uses tension sensor to detect tension data during tensile test.

[0007] However, during the implementation of the above technical solution, it is found that at least the following technical problems exist: different lengths of membrane are often tested during tensile test, and if the tension sensing position cannot be adjusted with different lengths of membrane during testing of different lengths, the detection data will be deviated, and it is difficult to measure accurate data.

[0013] Preferably: the base is rotatably mounted with a roller.

[0014] Preferably: the side end of the base is fixedly mounted with a scale.

[0015] (Three) beneficial effects

[0016] I. If the two slides are away from each other, the pull ropes at both ends of the tension sensor are simultaneously subjected to tension, which will cause the pull ropes to rotate the winding reels (the left winding reel rotates clockwise and the right winding reel rotates counterclockwise) to release more pull ropes, ensuring that the tension sensor will not be pulled due to the principle of the two slides, and ensuring that the tension sensor is always located at the midpoint of the two slides. The winding reels will charge the winding springs at both ends during this process. If the two slides are close to each other, the winding springs will release the stored energy to rotate the winding reels (the left winding reel rotates counterclockwise and the right winding reel rotates clockwise), winding up the excess pull ropes, keeping the tension sensor and pull ropes in a tense state, allowing the tension sensor to adjust to different lengths of the roll material, achieving the effect of improving measurement accuracy.

[0017] II. After clamping, the motor is started in the forward direction to drive the second two-way threaded rod to rotate, causing the two slides to pull the roll material towards both ends simultaneously. At the same time, the two slides will also pull the tension sensor through the pull ropes, causing the tension sensor to record the tensile data. The two slides will slide during the stretching process, and the scale can be used to observe the displacement data, achieving the effect of simulating the stretching of the roll material caused by thermal expansion and contraction of buildings in a natural environment.

[0025] Embodiment

[0026] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the technical scheme in the embodiment of the application effectively solves the technical problem that different lengths of the coiled material are often tested in the tensile test, and when testing different lengths of the coiled material, if the tensile sensing position cannot be adjusted to follow the different lengths of the coiled material, the detection data will be deviated, and it is difficult to measure accurate data.

[0027] In view of the problems in the prior art, the utility model provides a waterproof coiled material tensile property detection clamp, including base 1 and tensile sensor 7, base 1 is symmetrically slidably installed with sliding frame 2, the inside fixed mounting of sliding frame 2 has winding wheel 3, the inside rotatable mounting of sliding frame 2 has first two -way threaded rod 4, the inside symmetrically slidably installed of sliding frame 2 has friction plate 5, the both ends symmetrically installed of winding wheel 3 has winding spring 6, the both ends symmetrically fixed mounting of tensile sensor 7 has pull rope 8, the sliding installation of sliding frame 2 has clamping plate 9.

[0028] The top of sliding frame 2 is screw mounted with one -way threaded rod 11, and the second two -way threaded rod 12 is rotatably installed on the base 1 symmetrically;Two friction plates 5 are respectively screw connected with the both ends of the first two -way threaded rod 4, two sliding frames 2 are respectively screw connected with the both ends of the second two -way threaded rod 12, the end of the pull rope 8 is fixedly connected with the winding wheel 3, and the both ends of the winding spring 6 are respectively fixedly connected with the sliding frame 2 and the winding wheel 3.

[0029] The side end of base 1 is rotatably installed with transmission rod 14, and the side end of base 1 is fixedly installed with motor 15;Transmission rod 14 drives the second two -way threaded rod 12 to rotate through the gear set at both ends, motor 15 drives transmission rod 14 to rotate through the gear set, the side end of the first two -way threaded rod 4 is fixedly installed with the second knob 18, the top of the one -way threaded rod 11 is fixedly installed with the first knob 17, the drum 16 is rotatably installed on the base 1, and the scale 13 is fixedly installed on the side end of the base 1.

[0030] Working principle:

[0031] The first step, in use, the motor 15 starts to drive the transmission rod 14 to rotate through the gear set, and the transmission rod 14 drives the two second bidirectional threaded rods 12 to rotate through the gear set at both ends. Since the two carriages 2 are respectively threadedly connected with the two ends of the second bidirectional threaded rods 12, the two carriages 2 will slide inward or outward simultaneously under the action of the rotation of the second bidirectional threaded rods 12 until sliding to the required position. If a shorter coiled material is detected, the two carriages 2 are close to each other, and if a longer coiled material is detected, the two carriages 2 are away from each other, so as to be used for measuring the tensile property of coiled materials of different lengths. In this process, if the two carriages 2 are away from each other, the two ends of the tension sensor 7 are simultaneously subjected to tension, which will make the tension sensor 7 rotate (the left tension sensor 7 rotates clockwise, and the right tension sensor 7 rotates counterclockwise) to release more tension sensor 7, so as to ensure that the tension sensor 7 will not be pulled due to the principle of the two carriages 2, and at the same time ensure that the tension sensor 7 is always located at the midpoint position of the two carriages 2. The tension sensor 3 will make the two ends of the tension spring 6 store energy in this process. If the two carriages 2 are close to each other, the stored energy of the tension spring 6 will be released to make the tension sensor 3 rotate (the left tension sensor 3 rotates counterclockwise, and the right tension sensor 3 rotates clockwise), so as to wind up the excess tension sensor 8, so as to keep the tension sensor 7 and the tension sensor 8 in a tight state. When the position of the carriage 2 is adjusted, rotate the second knob 18 to make the first bidirectional threaded rod 4 rotate clockwise. Since the two friction plates 5 are threadedly connected with the two ends of the first bidirectional threaded rod 4, the two friction plates 5 will simultaneously slide inward until the two friction plates 5 can clamp the two ends of the tension sensor 3, so as to fix the tension sensor 3, avoiding the rotation of the tension sensor 3 during the tensile test, which will lead to inaccurate test data.

[0032] The second step is to put the coiled material into the roller 16, then pull out one side of the coiled material, pass the pulled out coiled material through the top ends of the two carriages 2, then rotate the two first knobs 17 to make the unidirectional threaded rod 11 rotate clockwise. Since the unidirectional threaded rod 11 is threadedly connected with the carriage 2, the clockwise rotation of the unidirectional threaded rod 11 will push the clamping plate 9 downward to slide, and the two clamping plates 9 that slide downward clamp the coiled material. After clamping, the motor 15 is started in forward rotation to drive the second bidirectional threaded rod 12 to rotate, so that the two carriages 2 simultaneously pull the coiled material to the two ends, and at the same time, the two carriages 2 will pull the tension sensor 7 through the tension sensor 8 to make the tension sensor 7 record the tensile data. The two carriages 2 will slide during the tensile process, and the displacement data can be observed through the scale 13.

[0033] Finally, it should be noted that: apparently, the above embodiments are merely examples for clearly illustrating the utility model, and are not limited to the implementation. For ordinary skilled persons in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to exhaust all the implementation. The obvious changes or variations derived therefrom are still within the protection scope of the utility model.
