Its quality is directly related to the service life of the building, the structural safety and the quality of life of the occupants. Once the waterproofing membrane has quality problems, it may cause leakage, and further cause a series of serious problems such as mold on the wall and structure corrosion, which brings huge cost to the maintenance and repair of the building. Therefore, the quality detection of the waterproofing membrane is very important, and the tensile property is one of the important indicators for evaluating the quality of the waterproofing membrane.

The existing tensile test equipment clamps and stretches the waterproofing membrane through a clamp, and the existing tensile test equipment clamp has only one stress point. When the outer surface of the waterproofing membrane is not flat enough, the stress is unstable during clamping, so that the waterproofing membrane may slip or locally deform at the clamp during stretching, resulting in inconsistency between the actual tensile force acting on the membrane and the data displayed by the instrument. In addition, it is difficult to find out the waterproofing membrane slipping in the clamp in time, so that the experimental data error is large, and it is difficult to fix the waterproofing membrane in time when it slips, which wastes time and test materials.
[0004] 2. The existing tensile test equipment does not have a corresponding protective structure. During the stretching of the waterproofing membrane, the tearing of the waterproofing membrane and the rupture of the membrane will pop out from the middle without a protective structure.

[0016] The technical scheme provided by the application has at least the following technical effects or advantages: 1. The use of a clamp assembly effectively solves the problem that the existing tensile test equipment all clamps and stretches the waterproof membrane through a clamp, and the existing tensile test equipment clamps only have one force point. When the outer surface of the waterproof membrane is not flat, the force is unstable during the clamping process, so that the waterproof membrane may slip or partially deform at the clamp during the stretching process, resulting in the actual tensile force acting on the membrane being inconsistent with the data displayed by the instrument. In addition, it is difficult to detect in time when the waterproof membrane slips in the clamp, so the tested experimental data has a large error. At the same time, it is difficult to fix the membrane in time when it slips, and multiple tests are required, wasting time and testing materials. The present invention can clamp and fix the waterproof membrane at multiple points through the clamp assembly, which is convenient for uniform force on the outer surface of the waterproof membrane when the outer surface of the waterproof membrane is uneven, thereby improving the accuracy of the tensile test. In addition, it can timely issue an alarm when the stretched membrane slips to prevent large test errors. At the same time, the slipping waterproof membrane can be fixed for the second time in time to avoid multiple tests due to slipping, saving time and experimental equipment.
[0017] 2. The use of protective components effectively solves the problem that the existing tensile test equipment does not have a corresponding protective structure. During the stretching process of the waterproof membrane, the waterproof membrane will be torn and broken, and the membrane will bounce off from the middle. Without a protective structure, these bounced waterproof membranes may cause harm to the testers and damage other items in the laboratory. The present invention can buffer the broken parts during the stretching process through the protective components, prevent the waterproof membrane from breaking and bouncing out to damage other items in the laboratory, and reduce the probability of injury to the experimenters.

As the connecting disk 775 rotates, the elastic rod 777 is forced to squeeze toward the second spring 776. At this time, the elastic rod 777 and the groove on the connecting disk 775 are disengaged, and the force of the elastic rod 777 and the groove on the connecting disk 775 is small. The engagement is used to keep the initial position of the rolling bar 774 fixed. At the same time, the contact portion between the groove on the connecting plate 775 and the elastic rod 777 is rounded, so that when the rolling bar 774 rotates, the elastic rod 777 and the groove on the connecting plate 775 are disengaged. The rotation of the rolling bar 774 drives the gear 778 to rotate, and the rotation of the gear 778 drives the first rack 779 to slide on the inner wall of the fixed block 773. The first rack 779 slides toward the fixed plate 71, forming an effect of increasing pressure on the waterproof membrane, thereby further increasing the waterproofing during the tensile test. The limiting force of the coiled material is convenient for preventing the waterproof coiled material from sliding further, achieving the effect of secondary fixing of the waterproof coiled material. At the same time, the rotation of the gear 778 drives the second rack 7710 to slide in the direction away from the fixed plate 71, and the adjustment block 7712 squeezes the button 7714, so that the alarm 7715 sounds an alarm to remind the staff that the waterproof coiled material has slipped. The position of the adjustment block 7712 on the second rack 7710 can be adjusted by rotating the plug rod 7713 to connect with different jacks 7711, which is convenient for controlling the adjustment block 7712 and the button 77 The spacing of 14 is used to set the alarm distance, so that an alarm can be sounded when the waterproof membrane slides to facilitate subsequent maintenance. By rotating the connecting disk 775, the groove on the connecting disk 775 and the elastic rod 777 are re-engaged to restore the first rack 779 and the second rack 7710 to their original positions for the next use. This allows the uniform clamping mechanism 76 to clamp the waterproof membrane at multiple points, and the auxiliary clamping mechanism 77 assists the uniform clamping mechanism 76 in limiting the position of the waterproof membrane, while reducing the probability of the waterproof membrane sliding sideways and improving the accuracy of the test data.
