Abstract
Description
Technical Field
[0001] This application belongs to the technical field of quality testing equipment, and specifically relates to a water tightness testing device for waterproof membranes. Background Technology
[0002] Before leaving the factory, waterproof membranes need to undergo a water tightness test to verify whether they meet the standard nail rod water tightness requirements. Before conducting the water tightness test, test samples need to be prepared. The required components include nail rods and plywood. After the test sample is prepared, a container is placed above and below the test sample. Distilled water is added to the container above the test sample. After a preset time, it is observed whether there is water in the container below the test sample.
[0003] If the amount of seepage is small after the preset time, relying solely on visual observation by the test personnel may lead to misjudgment and inaccurate test results. Utility Model Content
[0004] The purpose of this application is to provide a water tightness testing device for waterproof membranes, aiming to improve the accuracy of water tightness testing.
[0005] To achieve the above objectives, this application provides a watertightness testing device for waterproof membranes. The watertightness test sample includes a waterproof membrane, plywood, and nails. The waterproof membrane is adhered to the plywood, and the nails connect the waterproof membrane and the plywood. The watertightness testing device includes:
[0006] The lower clamp is used to hold the water tightness test sample and is disposed adjacent to the plywood. The lower clamp has an upward-opening water-receiving structure.
[0007] The upper clamp is used to place on the water tightness test sample and is set adjacent to the waterproof membrane, forming a water storage structure with a downward opening;
[0008] The first leakage sensor is arranged inside the water-receiving structure.
[0009] In some embodiments, the watertightness testing equipment further includes a second leakage sensor for placement at the end of the nail rod that passes through the plywood.
[0010] In some embodiments, the water tightness testing equipment further includes a third leakage sensor, which is arranged at the nail holes on the bottom surface of the plywood.
[0011] In some embodiments, the water tightness testing equipment further includes a fourth leakage sensor, which is arranged at the nail holes on the bottom surface of the waterproof membrane.
[0012] In some embodiments, the watertightness testing device further includes a controller electrically connected to the first leakage sensor, the controller being configured to:
[0013] Receive the leakage signal emitted by the first leakage sensor and record the corresponding leakage time.
[0014] In some embodiments, the water tightness testing equipment further includes a constant temperature chamber electrically connected to the controller, the constant temperature chamber including a display panel capable of displaying temperature, constant temperature time, and leakage time.
[0015] In some embodiments, the lower clamp includes a support plate, which is recessed to form a water-receiving groove as the water-receiving structure.
[0016] In some embodiments, the upper clamp includes a clamping plate and an upper sleeve. The clamping plate has a communicating hole, and the upper sleeve is installed at the communicating hole and connected to the top surface of the clamping plate. The cavity of the upper sleeve and the communicating hole form the water storage structure.
[0017] In some embodiments, the size of the support plate is larger than the size of the clamping plate.
[0018] In some embodiments, the water tightness testing equipment further includes a limiting member disposed on the lower clamp, the limiting member protruding from the top surface of the lower clamp and used for limiting engagement with the plywood.
[0019] In some embodiments, the water tightness testing device further includes a latching element disposed on the lower clamp, the latching element being capable of pressing the upper clamp downward.
[0020] Through the above technical solution, the water tightness testing equipment for waterproof membranes provided in this application has the following beneficial effects:
[0021] After the water tightness test sample is prepared, it is placed on the lower clamp with the plywood in contact with the lower clamp. Then, the upper clamp is placed on the water tightness test sample with the upper clamp in contact with the waterproof membrane. Subsequently, distilled water is filled into the water storage structure to start the water tightness test. During the test time, the water tightness of the waterproof membrane is determined by detecting the leakage in the water-receiving structure through the first leakage sensor. This replaces the method of visual observation by the test personnel and improves the accuracy of the water tightness test.

[0028] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.
[0029] The terminology of the water tightness testing equipment for the waterproof membrane 1 according to this application is described below with reference to the accompanying drawings.
[0030] The water tightness test includes a sample preparation stage and a testing stage. In the sample preparation stage, a water tightness test sample needs to be made using plywood 2, nail rods 3, and waterproof membrane 1. Specifically, the waterproof membrane 1 is first cut to a standard size and the anti-adhesive material on the waterproof membrane 1 is removed. Then, the waterproof membrane 1 is attached to the plywood 2 and the nail rods 3 are used to connect the waterproof membrane 1 and the plywood 2. In the testing stage, a water storage container filled with distilled water is placed on the top surface of the water tightness test sample, i.e., one side of the waterproof membrane 1. A water receiving container is placed on the bottom surface of the water tightness test sample, i.e., one side of the plywood 2.
[0031] like Figure 1 and Figure 2As shown, a specific embodiment of this application provides a water tightness testing device for a waterproof membrane 1. The water tightness testing device includes a lower clamp 9, an upper clamp 8, and a first leakage sensor 4. The lower clamp 9 is used to carry the water tightness test sample and is arranged adjacent to the plywood 2. An upward-opening water-receiving structure is formed on the lower clamp 9. The upper clamp 8 is used to place on the water tightness test sample and is arranged adjacent to the waterproof membrane 1. A downward-opening water-storing structure is formed. The first leakage sensor 4 is arranged inside the water-receiving structure.
[0032] Specifically, firstly, the lower clamp 9 is placed on the test platform. Then, the bottom surface of the plywood 2 of the water tightness test sample is placed on the lower clamp 9. Next, the upper clamp 8 is placed on the top surface of the waterproof membrane 1 of the water tightness test sample. Then, distilled water is filled into the water storage structure to start the test phase. During the test time, the first leakage sensor 4 is used to detect whether there is any leakage in the water-receiving structure to determine whether the water tightness of the waterproof membrane 1 is qualified. Since the first leakage sensor 4 has better detection accuracy, the accuracy of the water tightness test is significantly improved.
[0033] It should be noted that the structure and principle of the leak sensor for detecting leaks are well known to those skilled in the art and are not part of the core improvement of this application, so they will not be described in detail here.
[0034] It should be noted that, in the description of this application, unless otherwise stated, the terms "upper," "lower," "left," "right," "front," "rear," "inner," and "outer," etc., indicating orientation or positional relationships, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. When the absolute position of the described object changes, the relative positional relationship may also change accordingly. For ease of description, the specific directions in the specific embodiments of this application are shown by the arrows in the accompanying drawings.
[0035] Furthermore, the water tightness test sample is prepared by using a nail rod 3 to connect the waterproof membrane 1 and the plywood 2 that are bonded together. In other words, the nail rod 3 will leave nail holes on the waterproof membrane 1 and the plywood 2. Therefore, in addition to detecting the leakage in the water-receiving structure, the water tightness test also needs to detect the leakage at the nail holes on the bottom surface of the waterproof membrane 1, the leakage at the nail holes on the bottom surface of the plywood 2, and the leakage at the end of the nail rod 3 that passes through the plywood 2.
[0036] In some embodiments, the water tightness testing equipment further includes a second leakage sensor 5 and / or a third leakage sensor 6 and / or a fourth leakage sensor 7. The second leakage sensor 5 is positioned at the end of the nail rod 3 that passes through the plywood 2, the third leakage sensor 6 is positioned at the nail hole on the bottom surface of the plywood 2, and the fourth leakage sensor 7 is positioned at the nail hole on the bottom surface of the waterproof membrane 1. By installing leakage sensors at various locations where leakage needs to be detected, the water tightness of the test sample can be improved by detecting potential leaks at various points, thereby enhancing the accuracy of the water tightness test on the waterproof membrane 1.
[0037] It should also be noted that the testing phase of the water tightness test lasts for 3 days. Generally, the water tightness testing equipment and water tightness test samples need to be observed after 3 days. However, leakage may occur at any time before the 3 days are up. In fact, the testing phase can be declared over as soon as leakage occurs at all test points of the water tightness test sample, which results in a lot of wasted time.
[0038] In this application, by setting up leakage sensors at each detection location to provide timely feedback on the leakage situation at each detection location, the testing cycle of some waterproof membranes 1 with poor water tightness is shortened.
[0039] In some embodiments, the water tightness testing equipment further includes a controller electrically connected to the first leakage sensor 4, the controller being configured to receive a leakage signal emitted by the first leakage sensor 4 and record the corresponding leakage time.
[0040] Furthermore, the controller is also electrically connected to the second leakage sensor 5 and / or the third leakage sensor 6 and / or the fourth leakage sensor 7. The controller is configured to receive leakage signals emitted by the second leakage sensor 5 and / or the third leakage sensor 6 and / or the fourth leakage sensor 7 and record the corresponding leakage time.
[0041] In this application, the leakage time of each detection location is recorded by a controller to determine when the water tightness test sample starts to leak, which is beneficial for analyzing and judging the water tightness of the waterproof membrane 1.
[0042] It should also be noted that the water tightness test needs to be conducted at a test temperature of 4°C. Since the nail rod 3 is a metal part, a lower temperature may cause condensation to form at the end of the nail rod 3 and drip into the water-receiving structure of the lower clamp 9, which may lead to misjudgment.
[0043] In this application, leakage sensors are installed at each detection location to provide feedback on the leakage status at each location, and the test is declared over only after all leakage sensors have issued leakage signals, thereby reducing the possibility of misjudgment due to condensation and improving the accuracy of the water tightness test of the waterproof membrane 1.
[0044] Preferably, the water tightness testing equipment also includes an alarm device electrically connected to the controller. When all leakage sensors emit leakage signals, the controller controls the alarm device to remind the test personnel.
[0045] In some embodiments, the water tightness testing equipment also includes a constant temperature chamber electrically connected to the controller. The constant temperature chamber includes a display panel that can display the temperature, constant temperature time, and leakage time. The constant temperature chamber is used to maintain the test temperature required during the testing phase, and the display panel is used to visually display all the data during the testing phase, facilitating the collection of data for the water tightness test of the waterproof membrane 1, thereby aiding in the analysis and judgment of the water tightness of the waterproof membrane 1.
[0046] It should be noted that the structure and principle of the controller, constant temperature chamber and display panel are well known to those skilled in the art and are not part of the core improvement of this application, so they will not be described in detail here.
[0047] In some embodiments, the lower clamp 9 includes a support plate, and the upper clamp 8 includes a clamping plate. The top surface of the support plate and the bottom surface of the clamping plate form a clamping space for clamping the water tightness test sample. The top surface of the support plate is attached to the top surface of the plywood 2, and the bottom surface of the clamping plate is attached to the top surface of the waterproof membrane 1.
[0048] Furthermore, the support plate is recessed to form a water-receiving groove, with the groove opening facing upwards and covering the nail hole. A connecting hole is provided on the clamping plate, and an upper sleeve is installed at the connecting hole, with its bottom end connected to the top surface of the clamping plate. The cavity of the upper sleeve and the connecting hole form a water storage structure, and the nail hole is located within the connecting hole. In this application, testing can begin simply by pouring distilled water from the top of the upper sleeve into the cavity, greatly improving the convenience of water tightness testing.
[0049] Preferably, the size of the support plate is larger than the size of the clamping plate and larger than the size of the plywood 2, so as to provide stable support for the water tightness test sample and the clamping plate.
[0050] Optionally, the water tightness testing equipment also includes a limiting member disposed on the lower clamp 9. The limiting member protrudes from the top surface of the lower clamp 9 and is used to limit and cooperate with the plywood 2 to prevent the water tightness test sample from slipping off the support plate.
[0051] Optionally, the water tightness testing equipment also includes a latching element disposed on the lower clamp 9, which can press down on the upper clamp 8 so that the upper clamp 8 and the lower clamp 9 can provide sufficient clamping force for the water tightness test sample.
[0052] Preferably, the limiting member includes a fixed rod connected to the outer periphery of the lower clamp 9, the fixed rod extending upward, and the clamping member includes a rotating rod pivotally connected to the upper end of the fixed rod. The free end of the rotating rod is provided with a clamping block. The rotating rod can rotate in the vertical plane to drive the clamping block to abut against the top surface of the upper clamp 8 and apply a downward clamping force.
[0053] More preferably, the number of limiting members and fasteners is multiple and they are arranged at intervals along the outer periphery of the lower clamp 9.
[0054] During the sample preparation stage, firstly, the fourth leakage sensor 7 is fixed at the position corresponding to the nail rod 3 on the bottom surface of the waterproof membrane 1. Then, the bottom surface of the waterproof membrane 1 is pasted onto the top surface of the plywood 2. Subsequently, the nail rod 3 is nailed into the position corresponding to the nail rod 3 on the top surface of the waterproof membrane 1. Then, the third leakage sensor 6 is fixed at the nail hole on the bottom surface of the plywood 2. Finally, the second leakage sensor 5 is fixed at the end of the nail rod 3 that passes through the plywood 2.
[0055] During the testing phase, firstly, the lower clamp 9 is placed on the test platform with the opening of the water tank facing upwards. Then, the first leakage sensor 4 is placed into the water tank. Next, the water tightness test sample is placed on the lower clamp 9, and the upper clamp 8 is placed on the water tightness test sample. Then, the upper clamp 8 is pressed down using the buckle. Distilled water is then introduced into the upper sleeve. Then, the water tightness test sample, the upper clamp 8, and the lower clamp 9 are placed together in the constant temperature chamber. The first leakage sensor 4, the second leakage sensor 5, the third leakage sensor 6, and the fourth leakage sensor 7 are electrically connected to the controller. Finally, the test temperature and test time are set to start the test.
[0056] Throughout the testing process, the leakage at each leakage location of the watertightness test sample is detected by the first leakage sensor 4, the second leakage sensor 5, the third leakage sensor 6, and the fourth leakage sensor 7. The controller provides timely feedback on the leakage status and leakage time, thereby improving the accuracy of the watertightness test of the waterproof membrane 1 and shortening the test cycle.
