Description

Technical Field

[0001] The utility model relates to the technical field of waterproof coiled material testing, in particular to a waterproof coiled material puncture testing device. Background Art

[0002] Waterproofing membrane is a flexible material used for building waterproofing, usually made of asphalt, high molecular polymer or synthetic fiber reinforced material. It is laid on the surface of the building structure (such as roof, basement, tunnel, etc.) to form a continuous and seamless waterproof layer to prevent water penetration and protect the building structure from water damage. The puncture test is an important part of the quality control of waterproofing membranes, which is directly related to the safety and service life of waterproofing projects. Through the test, materials with strong damage resistance can be screened out to avoid overall waterproofing failure due to local damage and reduce the risk of leakage.

[0003] A waterproof membrane puncture test tool disclosed in Chinese patent CN220231296U includes a connecting frame, a support seat is fixedly connected to the middle of the upper end of the connecting frame, a base is fixedly connected to the upper end of the support seat, connecting slide bars are fixedly connected to the left and right sides of the upper end of the base, the outer side of the connecting slide bar is movably sleeved with a pressure plate, the upper end of the connecting slide bar is fixedly connected to the support plate, the opposite surfaces of the pressure plate and the support plate are fixedly connected with an extrusion plate by bolts, a pricking needle is movably inserted in the middle of the support plate, an adjustment ring is provided in the middle of the pressure plate, and the center of the pricking needle and the center of the adjustment ring are arranged opposite to each other up and down.

[0004] However, during the puncture test of waterproof membrane, the puncture test tooling may face the following problems in actual operation:

[0005] When conducting tests, most of them only record whether the maximum puncture force penetrates the waterproof membrane being tested, but do not test the degree of damage extension of the waterproof membrane under different forces, such as whether cracks are generated. Since waterproof membranes are mostly made of asphalt, high molecular polymers or synthetic fiber reinforced materials, they have a certain elasticity. The damage caused by the puncture test is relatively small. For example, when small cracks or small aperture perforations are generated, the deformation of the waterproof membrane being tested will rebound after the puncture head is retracted, making it impossible to accurately determine whether the waterproof membrane being tested is damaged. At the same time, the changes in waterproof performance after the puncture test are not tested, which is out of touch with the key waterproof requirements of the actual waterproof membrane.

[0038] The working process is as follows:

[0039] S1. Before use, loosen the fixing knob 310, slide the fixing component 3 on the limit frame 2, adjust the horizontal height of the fixing component 3 according to the scale on the limit frame 2, and after adjusting to the height required for detection, tighten the fixing knob 310 to fix the horizontal height of the fixing component 3;

[0040] S2, remove the fixing ring 43 from the connecting column 414, and then adjust the number of weight plates 42 according to the weight required for the test, thereby adjusting the weight of the puncture test assembly 4, and after the adjustment is completed, fix the fixing ring 43 on the connecting column 414 through the threaded groove 415 to fix the weight plate 42;

[0041] S3, the piercing member 44 is fixedly mounted on the connecting seat 411 by means of the fixing bolt 412, the piercing test assembly 4 is slid upwards, so that the connecting column 414 is inserted into the plug hole 302, and the piercing test assembly 4 is further slid upwards, so that the clamping block 304 is clamped into the clamping groove 416, and the connecting column 414 is limited, thereby fixing the position of the piercing test assembly 4;

[0042] S4. Fix the waterproofing membrane to be tested on the connecting ring 107 through the pressure ring 108, add a small amount of water into the pressure ring 108, and immerse the waterproofing membrane in the water. Close the valve on the discharge pipe 102, and start the air pump 103, so that the air pressure inside the cavity 101 is greater than the external air pressure;

[0043] S5. When in use, the connecting button 307 is pulled away from the connecting block 301. The connecting button 307 drives the block 304 to slide in the slide groove 303 through the connecting rod 306. The elastic member 305 contracts, and the block 304 slides out of the slot 416, releasing the limit on the connecting column 414.

[0044] S6, the puncture test assembly 4 falls due to its own gravity, and the puncture member 44 hits the waterproof membrane to be tested. When the waterproof membrane is not punctured, the water surface in the pressure ring 108 is calm and free of bubbles;

[0045] S7. When the damage caused by the puncture test is small, such as a small crack or a perforation with a small aperture, bubbles will be generated on the water surface in the pressure ring 108 because the air pressure inside the cavity 101 is greater than the external air pressure;

[0046] S8. When the damage caused by the puncture test is large, the water in the pressure ring 108 will directly leak into the cavity 101;

[0047] S9. When the piercing member 44 pierces the waterproof membrane to be tested, the buffer plate 106 on the connecting frame 104 buffers the piercing member 44 to prevent the piercing member 44 from directly hitting the base 1 and causing damage to the piercing member 44 or the base 1.

[0048] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
