Description

Technical Field

[0001] This utility model relates to the technical field of testing devices for building waterproofing materials, and in particular to a testing device for building waterproofing materials. Background Technology

[0002] Building waterproofing material testing equipment is a professional device used to verify whether the performance of waterproofing materials (such as waterproof membranes, waterproof coatings, waterproof boards, etc.) meets industry standards and engineering requirements. It can test key indicators such as waterproofing, mechanical properties, and durability of materials, and is widely used in building engineering quality testing institutions, waterproofing material manufacturers, and research institutions.

[0003] The applicant discovered through a search that a Chinese patent, "A Testing Device for Building Waterproofing Materials," with publication (announcement) number "CN222559592U," primarily achieves the effect of fixing the material through the cooperative use of various fixing components. By placing the material on top of a placement plate and rotating a handle to drive the threaded rod, which in turn rotates the bearing, the clamping plate is moved to the top of the material, facilitating clamping and fixing. Rubber pads are used to increase friction with the material, thereby ensuring a tighter fixation. The device aims to minimize material movement and drop during testing, thus improving its stability. However, this patent only has a single material fixing function and cannot solve the problem of firmly clamping waterproof materials of different thicknesses while simultaneously outputting stable tensile force for effective pulling. In actual use, it cannot adapt to the firm clamping of materials of different thicknesses, and the materials are prone to slipping or being damaged during testing, making it impossible to output tensile force for effective pulling. This may prevent the performance of such core testing items, as only basic fixing operations can be completed, and it may not be able to provide key data for material quality assessment. Therefore, we propose a testing device for building waterproof materials. Utility Model Content

[0004] The purpose of this invention is to provide a testing device for building waterproofing materials, in order to solve the problem mentioned in the background art that only has a single material fixing function, which cannot solve the problem of stable clamping of waterproofing materials of different thicknesses, while also being able to stably output tensile force to achieve effective pulling. In actual use, it cannot be adapted to the stable clamping of materials of different thicknesses, and the materials are prone to slipping or being damaged during testing, thus failing to output tensile force to achieve pulling. This may result in the inability to carry out such core testing items, and only basic fixing operations can be completed, which may not be able to provide key data for material quality judgment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a testing device for building waterproofing materials, including a workbench, a support frame fixedly installed on the top of the workbench, and tensile testing components provided on the top and bottom of the workbench. The tensile testing components include a hydraulic cylinder and a fixed frame. The hydraulic cylinder is connected to a sliding sleeve through a connecting block, and the fixed frame is connected to a protruding pressure plate through an electric telescopic rod. A rectangular groove is provided on the top of the workbench, and a guide rod is fixedly connected to the inner wall of the rectangular groove.

[0006] As a preferred embodiment, the hydraulic cylinder is fixedly connected to the bottom of the workbench, the bottom of the connecting block is fixedly connected to the left end of the hydraulic cylinder, and the top of the connecting block is fixedly connected to the surface of the sliding sleeve.

[0007] As a preferred embodiment, the inner wall of the sliding sleeve is slidably connected to the outer wall of the guide rod, and two sets of the fixed frame, the electric telescopic rod, and the convex pressure plate are provided. One set of the fixed frame is fixedly installed on the top right side of the workbench.

[0008] As a preferred embodiment, another set of fixed frames is fixedly connected to the top of the sliding sleeve, the two sets of electric telescopic rods are respectively fixedly connected to the top of the two sets of fixed frames, and the two sets of convex pressure plates are respectively fixedly connected to the lower ends of the two sets of electric telescopic rods.

[0009] As a preferred embodiment, a leakage detection component is provided below the support frame. The leakage detection component includes a rectangular frame and a hose. The rectangular frame is fixedly installed on the top of the workbench and located directly below the support frame. A color-changing paper is provided on the top of the rectangular frame.

[0010] As a preferred embodiment, the upper end of the flexible tube is fixedly connected to a connecting pipe, the lower end of the connecting pipe is fixedly connected to a straight pipe, the straight pipe is fixedly connected to the inner top wall of the support frame, and multiple sets of nozzles distributed at equal intervals are fixedly installed at the bottom of the straight pipe, with all sets of nozzles positioned directly above the color-changing paper.

[0011] The technical effects and advantages of this utility model are as follows: 1. The tensile testing component, when testing the waterproof material, firstly, the electric telescopic rod drives the convex pressure plate to move up and down along the hollow groove at the top of the fixed frame. Utilizing the two sets of convex structures of the bottom wall inside the fixed frame and the convex pressure plate, the waterproof material is tightly clamped from both the top and bottom. At the same time, the hollow groove provides ample extension space for the electric telescopic rod, which can flexibly adapt to waterproof materials of different thicknesses, effectively preventing material slippage during the testing process and ensuring clamping stability. After the material is clamped, the operator can use the hydraulic cylinder as the pulling power source, and drive the sliding sleeve to slide along the guide rod through the connecting block, so that a set of fixed frames moves with the sliding sleeve, thereby pulling the waterproof material. In summary, the cooperation of each component can solve the problem of stable clamping of materials of different thicknesses and stably output the tensile force. 2. Through the set leakage detection component, external water can be delivered to the nozzle through hoses, connecting pipes, and straight pipes. The nozzle will evenly spray water onto the color-changing paper at the top of the rectangular frame below and the waterproof material above, simulating an actual waterproofing scenario. If there is a leakage problem with the waterproof material, water will seep into the color-changing paper below, causing the color-changing paper to change color. Staff can directly judge whether the material is leaking by observing the color change of the color-changing paper. There is no need for complicated detection steps. The detection process is intuitive and efficient. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see the appendix Figure 1 - Appendix Figure 5A testing device for building waterproofing materials includes a workbench 1, a support frame 2 fixedly installed on the top of the workbench 1, and a tensile testing component 3 provided on the top and bottom of the workbench 1. The tensile testing component 3 includes a hydraulic cylinder 301 and a fixing frame 304. The hydraulic cylinder 301 is connected to a sliding sleeve 303 through a connecting block 302. The fixing frame 304 is connected to a protruding pressure plate 306 through an electric telescopic rod 305. A rectangular groove 307 is opened on the top of the workbench 1. A guide rod 308 is fixedly connected to the inner wall of the rectangular groove 307. The hydraulic cylinder 301 is fixedly connected to the bottom of the workbench 1. The bottom of the connecting block 302 is fixedly connected to the left end of the hydraulic cylinder 301, and the top of the connecting block 302 is fixedly connected to the surface of the sliding sleeve 303.

[0016] The hydraulic cylinder 301 is fixed at the bottom of the workbench 1 and is the power source that provides the pulling force. It drives the connecting block 302 and subsequent components to move through its own extension and retraction, thereby applying a pulling force to the waterproof material. The guide rod 308 is fixed on the inner wall of the rectangular groove 307, and the sliding sleeve 303 can slide along it, providing guidance for the movement of the sliding sleeve 303 and ensuring the stability and straightness of the movement of the sliding sleeve 303 and related components.

[0017] The inner wall of the sliding sleeve 303 is slidably connected to the outer wall of the guide rod 308. Two sets of fixed frames 304, electric telescopic rods 305 and convex pressure plates 306 are provided. One set of fixed frames 304 is fixedly installed on the top right side of the workbench 1, and the other set of fixed frames 304 is fixedly connected to the top of the sliding sleeve 303. The two sets of electric telescopic rods 305 are respectively fixedly connected to the top of the two sets of fixed frames 304, and the two sets of convex pressure plates 306 are respectively fixedly connected to the lower end of the two sets of electric telescopic rods 305.

[0018] The inner bottom wall of both sets of fixing frames 304 is provided with the same convex rib pressure plate 306 as the two sets of convex rib pressure plates 306. The top of both sets of fixing frames 304 is provided with a hollow groove, which is used for the electric telescopic rod 305 to extend and retract vertically.

[0019] Specifically, when testing the waterproof material using the set tensile testing component 3, the electric telescopic rod 305 drives the convex pressure plate 306 to move up and down along the top hollow groove of the fixed frame 304. Utilizing the two sets of convex structures of the bottom wall inside the fixed frame 304 and the convex pressure plate 306, the waterproof material is clamped from both the top and bottom. The hollow groove provides telescopic space for the electric telescopic rod 305, adapting to waterproof materials of different thicknesses, preventing material slippage during testing, and ensuring clamping stability. After the material is clamped, the operator uses the hydraulic cylinder 301 as the pulling power source, driving the sliding sleeve 303 to slide along the guide rod 308 through the connecting block 302, causing a set of fixed frames 304 to move with the sliding sleeve 303, thus achieving the pulling of the waterproof material. In summary, the cooperation of each component can solve the problem of stable clamping of materials of different thicknesses and stably output the tensile force.

[0020] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 6 and appendix Figure 7 A water leakage detection component 4 is provided below the support frame 2. The water leakage detection component 4 includes a rectangular frame 401 and a hose 403. The rectangular frame 401 is fixedly installed on the top of the workbench 1 and located directly below the support frame 2. A color-changing paper 402 is provided on the top of the rectangular frame 401. A connecting pipe 404 is fixedly connected to the upper end of the hose 403. A straight pipe 405 is fixedly connected to the lower end of the connecting pipe 404. The straight pipe 405 is fixedly connected to the inner top wall of the support frame 2. Multiple sets of nozzles 406 are fixedly installed at the bottom of the straight pipe 405. All sets of nozzles 406 are located directly above the color-changing paper 402.

[0021] The upper end of the flexible hose 403 is fixedly connected to the connecting pipe 404. Its main function is to transport water and guide external water to the connecting pipe 404, providing a water flow channel for the subsequent spray from the nozzle 406. It is an important component for water flow transmission in leak detection. The main function of the nozzle 406 is to convert the water flow transported by the straight pipe 405 into a uniform water flow or water mist, simulating natural water spray or rain scenarios, and spraying water on the waterproof material placed in the rectangular frame 401 to test the waterproof performance of the material.

[0022] Specifically, through the set leak detection component 4, external water is delivered to the nozzle 406 via the hose 403, connecting pipe 404, and straight pipe 405. The nozzle 406 sprays water onto the color-changing paper 402 at the top of the rectangular frame 401 below and the waterproof material above, simulating an actual waterproofing scenario. If there is a leak in the waterproof material, water seeps into the color-changing paper 402 below, causing the color-changing paper 402 to change color. By observing the color change of the color-changing paper 402, the staff can determine whether the material is leaking. No complicated detection steps are required, and the detection process is intuitive and efficient.

[0023] Working principle of this utility model: This utility model is a testing device for building waterproof materials. First, the operator cuts the waterproof material to be tested to the required size. Then, one end of the material is placed in the fixed frame 304 on the top right side of the workbench 1, and the other end is placed in the fixed frame 304 on the top of the sliding sleeve 303. At the same time, the waterproof material is covered over the color-changing paper 402 on the top of the rectangular frame 401, ensuring that the area covered by the material corresponds to the area directly below the nozzle 406, thus completing the initial positioning of the material. Next, the operator activates the electric telescopic rods 305 on the top of the two sets of fixed frames 304. The electric telescopic rod 305 extends and retracts downward along the hollowed-out groove at the top of the fixed frame 304, driving the convex pressure plate 306 to move towards the material until the convex pressure plate 306 engages with the convex pressure plate 306 on the inner bottom wall of the fixed frame 304, clamping the waterproof material from both the top and bottom. After the material is clamped, the operator activates the hydraulic cylinder 301 at the bottom of the workbench 1. The hydraulic cylinder 301, acting as a pulling force source, begins to extend and retract, driving the sliding sleeve 303 to slide along the guide rod 308 on the inner wall of the rectangular groove 307 via the connecting block 302. As the sliding sleeve 303 moves, the fixed frame 304 fixed at its top moves accordingly, and the workbench 1... The top right fixing frame 304 remains stationary, and the two sets of fixing frames 304 form a state where one end is fixed and the other end is pulled, realizing the tension of the waterproof material. The staff observes the material's deformation under stress and records the tensile force data at the time of breakage to complete the material's tensile performance test. After the tensile test is completed, the staff ensures that the waterproof material is still covering the color-changing paper 402 on top of the rectangular frame 401. Then, the external water source is connected to the inlet end of the hose 403, the water source switch is turned on, and the external water source is delivered through the hose 403 to the connecting pipe 404, and then through the connecting pipe 404 into the straight pipe 405, and finally through the straight pipe 405. Multiple nozzles 406 at the bottom spray downwards, positioned directly above the color-changing paper 402. These nozzles convert the water flow into a uniform stream, spraying water onto the surface of the waterproof material to simulate a rain scenario in actual use. Staff continuously observe the state of the color-changing paper 402 during the water spraying process. If the waterproof material has a leakage defect, the water sprayed on the material surface will penetrate the material and drip onto the color-changing paper 402, causing the paper to change color. Staff can directly determine whether the material is leaking by observing whether the paper changes color, without any additional complicated operations, thus completing the test of the material's waterproof performance.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
