DETAILED DESCRIPTION
[0018] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.
[0019] Embodiment: A device for detecting water resistance of building materials, such as Figure 1 and Figure 2 As shown, it includes a box body 1, a water pump 7, a water suction pipe 8, a fixing frame 9, a cylinder 10, a pressure plate 11 and a clamping assembly. The water pump 7 is bolted to the lower left part of the box body 1, and the water inlet of the water pump 7 is communicated with the box body 1. A water suction pipe 8 is arranged between the water outlet of the water pump 7 and the upper left part of the box body 1. A fixing frame 9 is fixedly connected between the front and rear sides of the top of the box body 1, and a cylinder 10 is bolted to the top of the fixing frame 9. A pressure plate 11 is fixedly connected to the telescopic rod of the cylinder 10, and the pressure plate 11 is slidably connected to the inner wall of the box body 1. The pressure plate 11 is located in the upper inner part of the box body 1. By controlling the extension of the telescopic rod of the cylinder 10, the pressure plate 11 slides downward, so that the water in the upper inner part of the box body 1 can be pressurized until the water pressure in the upper inner part of the box body 1 reaches the specified test pressure value, so that the water pressure to be detected can be adjusted according to waterproof materials of different materials. A clamping assembly is arranged in the box body 1, and the clamping assembly is located directly below the pressure plate 11.
[0020] like Figure 2 and Figure 3 As shown, the clamping assembly includes a limit plate 2, a first clamp plate 3, a second clamp plate 4, a handle 5 and a support plate 6. The middle parts of the front and rear sides of the box body 1 are symmetrically fixedly connected to the limit plate 2. The rear sides of the first clamp plate 3 and the second clamp plate 4 are hingedly connected by hinges. The first clamp plate 3 and the second clamp plate 4 are both provided with sealing strips. The first clamp plate 3 is located at the lower side of the second clamp plate 4. When the first clamp plate 3 and the second clamp plate 4 are in contact, the sealing strip can ensure that the edge between the first clamp plate 3 and the waterproof membrane to be tested is tightly sealed, and at the same time ensure that the edge between the waterproof membrane to be tested and the second clamp plate 4 is tightly sealed. The first clamp plate 3 and the second clamp plate 4 are in contact and can slide through between the upper and lower limit plates 2. The right side of the first clamp plate 3 is fixedly connected to the handle 5, and the middle right side of the box body 1 is fixedly connected to the support plate 6, and the support plate 6 is located below the first clamp plate 3.
[0021] like Figure 4 and Figure 5As shown, it also includes a posting plate 12, a pressure spring 13 and a lifting assembly. The posting plate 12 is slidably provided in the first clamping plate 3, and a pressure spring 13 is connected between the posting plate 12 and the first clamping plate 3. A lifting assembly is provided on the first clamping plate 3; the lifting assembly includes an inclined top block 14 and a reset spring 15. The inclined top block 14 is composed of a connecting rod and two wedge blocks. The two connecting rods are symmetrically slidably connected to the front and rear sides of the first clamping plate 3. The front and rear ends of the two connecting rods are connected to wedge blocks. The left sides of the wedge blocks at the ends away from each other of the two connecting rods are all inclined. The inclined surfaces of the wedge blocks are in contact with the box body 1. The top surfaces of the wedge blocks at the ends close to each other of the two connecting rods are The inclined surface of the wedge block contacts and cooperates with the pasting plate 12. A return spring 15 is connected between the inclined top block 14 and the first clamping plate 3. The return spring 15 is wound around the connecting rod of the inclined top block 14. When the first clamping plate 3 drives the inclined top block 14 to slide to the left, the inclined surface of the wedge block on the left side will contact the box body 1. The box body 1 can squeeze the wedge blocks on the left side of the front and rear sides to move closer to each other. The return spring 15 is compressed so that the inclined surface of the wedge block on the top can contact the pasting plate 12, thereby squeezing the pasting plate 12 to move upward, and the pressure spring 13 is stretched to make the test paper move upward and contact closely with the bottom of the waterproof membrane to be tested.
[0022] Initially, the return spring 15 is in a compressed state and the pressure spring 13 is in a stretched state; when it is necessary to test the waterproofness of the waterproof membrane, first move the testing device to the corresponding position, then cut the waterproof membrane to be tested according to the specified size, and ensure that the sample is cut smoothly and without damage, then pull the handle 5 to the right, so that the first clamping plate 3 slides to the right, driving the second clamping plate 4 to slide to the right, until the first clamping plate 3 and the second clamping plate 4 slide out from between the upper and lower limit plates 2, the first clamping plate 3 can drive the inclined top block 14 to move to the right and disengage from the box body 1, at this time, the return spring 15 can restore its original state, driving the inclined top blocks 14 on the front and rear sides to move to the side away from each other, so that the inclined top block 14 is separated from the pasting plate 12, at this time, the pressure spring 13 can restore its original state, driving the pasting plate 12 to move downward; at this time, the first clamping plate 3 and the second clamping plate 4 can be placed on the supporting plate 6, and then the second clamping plate 4 is rotated open, so that the second clamping plate 4 is out of contact with the first clamping plate 3. After the paving 12 is completed, the first clamping plate 3 and the second clamping plate 4 are completely embedded between the upper and lower limit plates 2, thereby completing the clamping and placement of the test paper and the waterproof membrane to be tested;At this time, the water pump 7 is controlled to start working, and the water in the lower part of the inner side of the box body 1 can be sprayed to the surface of the waterproof membrane to be tested between the first clamping plate 3 and the second clamping plate 4 through the water pumping pipe 8. After the water injection is completed, the telescopic rod of the control cylinder 10 is extended to make the pressing plate 11 slide downward, so that the water in the upper part of the inner side of the box body 1 can be pressurized until the water pressure in the upper part of the inner side of the box body 1 reaches the specified test pressure value, and the extension of the telescopic rod of the control cylinder 10 is stopped and maintained for a period of time, so that the waterproof property of the waterproof membrane to be tested is tested under the specified water pressure. After the test is completed, the telescopic rod of the control cylinder 10 is shortened to make the pressing plate 11 slide upward and reset. Then pull out the first clamping plate 3 and the second clamping plate 4, and observe the test paper. The waterproofness of the tested waterproof membrane can be judged according to whether there are water drops or wet marks on the test paper. If no penetration occurs after a specified time under a specified pressure, it means that the waterproof performance of the waterproof membrane meets the standard requirements. Repeat the above steps to test the waterproofness of the next waterproof membrane to be tested under a specified water pressure. In this way, the water pressure in the box body 1 can be adjusted accordingly according to the test requirements, so as to meet the different water pressure test requirements of waterproof materials of different materials. It has a wide range of applications, is easy to operate, and saves time and effort. ;
[0023] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
