[0002] Waterproof membrane is a flexible building material that can be rolled into rolls. It is mainly used in building walls, roofs, tunnels, highways, landfills, etc., to resist external rainwater and groundwater seepage. As a leak-proof connection between the foundation and the building, it is the first line of defense in the entire waterproofing project and plays a crucial role. To ensure the waterproof membrane has high strength, tensile performance tests are required on the non-woven membrane and its raw material film. Tensile test specimens for non-woven membrane and raw material film require cutting 5 strips each horizontally and vertically, each 220mm long * 25mm wide. In existing technology, a steel ruler is used for measurement. Each cutting requires holding the ruler down by hand, which carries the risk of scratches. Repeatedly moving the ruler results in low efficiency, poor dimensional accuracy, and affects the testing results. Summary of the Invention

[0010] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0011] This utility model discloses a tool for preparing tensile test specimens of non-woven roll materials and raw material films. The tool mainly includes a pressure plate 1, on which longitudinal cutting grooves 2 are evenly spaced at 25 mm intervals, forming a specimen cover plate 3. The specimen cover plate 3 has marking holes 4 corresponding to the marking positions on the specimen, and transverse cutting marking holes 5 at both ends of the specimen cover plate 3 corresponding to the transverse cutting positions. The tool is operated by pressing the pressure plate 1 onto the non-woven roll material or raw material film to be cut in the desired direction (transverse or longitudinal), and then operating a paper cutter along the longitudinal cutting grooves 2 to cut the non-woven roll material or raw material film. The roll material or raw material film is cut. After longitudinal cutting, the distance marking line is detected by marking the extensometer through the marking hole 4 using a marking pen. The transverse cutting line is marked through the transverse cutting marking hole 5. Then, the pressure plate 1 is removed, and one straight edge of the pressure plate 1 is aligned with the transverse cutting line. A paper cutter is used to cut transversely along the straight edge of the pressure plate 1 to obtain a set of tensile test specimens. The pressure plate 1 is relatively large, making it easy to press and preventing slippage during cutting, thus ensuring cutting accuracy, dimensional accuracy of the tensile test specimens, and accuracy of testing. It is easy to press and avoids the risk of hand injury from the cutter. It effectively improves sample preparation efficiency and reduces labor costs.

[0012] In this embodiment, the pressure plate 1 is provided with a handle 6 for easy operation.

[0013] In this embodiment, the four corners of the pressure plate 1 are rounded.

[0014] Work process: Operate the pressure plate 1 and press it onto the non-woven roll material or raw material film to be cut in the desired direction (horizontal or vertical). Operate the paper cutter to cut the non-woven roll material or raw material film along the longitudinal cutting groove 2. After the longitudinal cutting is completed, use a marking pen to mark the extensometer marking line through the marking hole 4 to detect the distance marking line. Mark the transverse cutting line through the transverse cutting marking hole 5. Then remove the pressure plate 1, align one straight edge of the pressure plate 1 with the transverse cutting line, and use the paper cutter to cut along the straight edge of the pressure plate 1 to obtain a set of tensile test specimens. The pressure plate 1 is relatively large, making it easy to press and preventing slippage during the cutting process, thus ensuring cutting accuracy, dimensional accuracy of the tensile test specimens, and accuracy of the test. It is easy to press and avoids the risk of cutting hands with the cutter. It effectively improves sample preparation efficiency and reduces labor costs.
