[0002] With the development of the construction industry, the quality of building waterproofing projects has become increasingly critical. Waterproofing materials, as the core of waterproofing projects, directly affect the waterproofing effect, building durability, and safety. Tensile properties are an important indicator for measuring the quality of waterproofing materials, reflecting their ability to resist deformation and fracture under stress. Accurate testing of tensile properties is of great significance for ensuring the quality of building waterproofing.
[0003] Existing testing devices typically lack effective protective measures during the testing process. When the waterproofing material suddenly breaks during tensile testing, the impact force generated at the moment of fracture may cause material fragments or clamp components to be ejected, posing a significant risk of injury to testing personnel in the vicinity. Therefore, a tensile testing device for building waterproofing materials is needed to address these issues. Utility Model Content

[0025] The overall effect of embodiment 2 is as follows: Support legs 2 are fixedly connected to the bottom and near both ends of the ring plate 1. The support legs 2 are U-shaped, which can support the bottom of the ring plate 1. Sliding grooves 6 are provided on both inner walls of the ring plate 1. Limiting rods 8 are fixedly connected inside the sliding grooves 6. Limiting blocks 7 are slidably connected to the surface of the limiting rods 8. The limiting blocks 7 are fixedly connected to the moving plate 4, which can limit the movement of the moving plate 4. Limiting posts 15 are slidably connected through the protrusion of the pressing plate 14. The two ends of the limiting posts 15 are respectively connected to the top and bottom of the moving plate 4. The U-shaped plate 12 is fixedly connected to the inner wall, which can limit the position of the extrusion plate 14. Magnets 18 are embedded and fixedly connected to the top of the ring plate 1 and the bottom of the protective cover 17. The two magnets 18 are compatible with each other, which can fix the protective cover 17. A protrusion 19 is fixedly connected to the surface of the protective cover 17 near the center, which can facilitate the opening of the protective cover 17. A programmable logic controller 21 is embedded and fixedly connected to one end of the ring plate 1. A control panel 22 and a display screen 23 are fixedly connected to the surface of the ring plate 1, which can control the device.
[0026] Working principle: By placing the material between the fixed plate 11 and the extrusion plate 14, the programmable logic controller 21 can be controlled by the control panel 22. The programmable logic controller 21 can then control the hydraulic cylinder 13, which in turn drives the extrusion plate 14 to descend, causing the triangular plate 16 to clamp and fix the two ends of the material. Then, by covering the protective cover 17, the programmable logic controller 21 controls the drive motor 5 to drive the bidirectional screw 3 to rotate. The rotation of the bidirectional screw 3 can drive the moving plates 4 at both ends to move to both sides. At this time, the material can be subjected to tensile testing, and the test data can be displayed on the display screen 23 through the force sensor 9.
