Description

Technical Field

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

[0002] When conducting a tensile test on asphalt waterproofing membranes, it is necessary to use a clamp to clamp the two ends of the waterproofing membrane sample, and then use a tensile machine to stretch it. Figure 1 As shown, two clamps are used to clamp the two ends of the roll material sample. However, since the asphalt waterproofing roll material contains sticky substances such as asphalt, a large amount of sticky substances will adhere to the serrated clamps during the clamping and stretching process, causing the sample to slip easily during the stretching process in subsequent tests, and its tensile effect cannot be measured; and the clamp is inconvenient to disassemble and difficult to clean. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a waterproof coiled material tensile strength test fixture, which can conveniently clean the clamp.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a waterproof membrane tensile strength test fixture, including a first base and a second base, a sliding rod is fixed between the first base and the second base, a clamping device is sleeved on the sliding rod, and a clamping rod is threadedly connected on the second base, the clamping device includes two clamping plates sleeved on the sliding rod, the two clamping plates are arranged opposite to each other, and a clamping head is detachably provided on the inner side of the clamping plate.

[0005] Preferably, a limiting column is provided on the rear side of the clamping head, and a groove matching with the limiting column is provided on the surface of the clamping plate.

[0006] Preferably, a magnetic attraction layer is provided at the end of the limiting column.

[0007] Preferably, the clamping head is a sawtooth structure.

[0008] Preferably, a return spring is sleeved on the slide bar between the two clamping plates.

[0009] Preferably, baffles for limiting the position of the clamping head are provided at the top and bottom of the clamping plate.

[0010] The utility model provides a waterproof coiled material tensile test fixture, which is provided with a detachable clamping head. After each waterproof coiled material tensile test, the clamping head can be detached for cleaning to remove sticky substances adhered to the toothed structure, thereby ensuring the accuracy of subsequent tests.
