[0002] In building engineering, waterproof materials are needed, and waterproof coiled materials are one of the waterproof materials. Waterproof coiled materials are mainly used in building walls, roofs, tunnels, highways, landfills, etc., to play a role in resisting external rainwater and groundwater seepage. It is a flexible building material product that can be coiled into a roll shape. As a leak-free connection between the project foundation and the building, it is the first barrier for the overall project waterproofing and plays a crucial role in the whole project. Before the waterproof coiled material leaves the factory, in order to meet the use requirements, it is necessary to test the tensile strength and elongation rate of the waterproof coiled material specimen. At this time, two sets of fixtures are needed to fix the two ends of the strip-shaped waterproof coiled material specimen respectively.

However, only through simple fixation, the stability is relatively low, and it is very likely that the position of the waterproof coiled material specimen will move or even break away during the test. Therefore, it is necessary to propose a building waterproof material detection fixture to solve the above problems. Summary of the Invention

When the first screw rod is rotated accordingly, the first clamping plate can be driven to move leftward, so that the waterproof coiled material specimen can be clamped for the first time through the cooperation of the right end of the first clamping plate and the pressure block. Then, a part of the waterproof coiled material specimen located inside the connecting frame is in a tensioned state. By rotating the second screw rod, the waterproof coiled material specimen can be clamped for the second time in cooperation with the upper ends of the second clamping plate and the pressure block. Since the upper end of the first clamping plate and the upper end of the pressure block are on the same horizontal plane, and the right end of the second clamping plate extends to the right of the pressure block, the part corresponding to the first clamping plate and the second clamping plate can be completely pressed.
