Description

Technical Field

[0001] The present invention belongs to the technical field of waterproof detection of building boards, and specifically relates to a device for determining the quality of environmentally friendly building boards. Background Art

[0002] Environmentally friendly building boards undertake various functions in building structures, such as load-bearing, partitioning, and enclosing. And the waterproof performance is a crucial performance index among them. Whether it is the roof and exterior walls outside the building or the humid environment areas such as bathrooms and kitchens inside the building, building boards will inevitably come into contact with moisture.

[0003] For roof and exterior wall boards, the waterproof performance is directly related to the effectiveness of the overall waterproof system of the building. Once the waterproofing of the boards in these parts fails, moisture such as rainwater and snowmelt will seep into the interior of the building structure, resulting in damp walls, mildew, and a decline in thermal insulation performance. Long-term accumulation may cause damage to the building structure, such as corrosion of steel bars and erosion of concrete, seriously affecting the service life and safety of the building. In addition, good waterproof performance can also improve the durability of building boards to a certain extent, reduce the decline in physical properties and appearance damage caused by moisture erosion, and reduce building maintenance costs and repair frequencies, thereby realizing the economy and sustainability of the entire building life cycle.

[0004] When conducting waterproof tests on boards, generally, the boards are clamped in a U-shaped clamping tool, and then the boards are subjected to water spraying and water storage tests. If there is a gap between the clamping tool for clamping the boards and the side plates of the boards, water will flow down from the gap between the boards and the clamping tool, and some water will flow onto the bottom surface of the boards. If the staff does not notice in time, it will be considered that the water on the boards penetrates through the boards and flows to the bottom of the boards, thus misleading the staff and resulting in inaccurate test results.

[0031] 1. The environmentally friendly building board quality measuring device described in the present invention can block water from flowing to the outside of the circular sealing strip when the board is subjected to water sprinkling and water storage detection by utilizing the circular sealing strip, thereby preventing water from flowing to the bottom of the board through the gap when there is a gap between the board and the upper clamp frame and the lower clamp frame. If the staff does not find it in time, they will think that the water on the board has penetrated the board and flowed to the bottom of the board, which will mislead the staff and cause inaccurate detection results. At the same time, if the surface of some boards is not smooth, part of the water will flow from under the circular sealing strip. At this time, the rectangular sealing strip can first block this part of the water. If part of the water passes through the rectangular sealing strip, the removal component can discharge the water at this time, thereby preventing the water from flowing to the bottom of the board through the gap between the board and the upper clamp frame and the lower clamp frame.

[0032] 2. The environmentally friendly building board quality measuring device described in the present invention, if the surface of the board is not smooth, causing part of the water to flow through the gap between the rectangular sealing strip and the board, controls the first motor to rotate, and the first motor will drive the transmission belt to rotate through the rotating rod, and the rotating transmission belt will drive the water-absorbing cotton layer to rotate. When water wants to pass through the water-absorbing cotton layer, the water-absorbing cotton layer will absorb part of the water to prevent the water from continuing to flow. Since the transmission belt part extends to the outside, when the water-absorbing cotton layer follows the transmission belt to rotate to the outside after absorbing water, the squeezing roller will squeeze the water-absorbing cotton layer to squeeze out the water in the water-absorbing cotton layer. Subsequently, the water-absorbing cotton layer that squeezes out the water will circulate on the surface of the board, so as to continuously absorb the water flowing through the transmission belt, thereby preventing water from flowing through the transmission belt position and flowing to the bottom of the board.

[0033] 3. The environmentally friendly building board quality measuring device described in the present invention controls the first piston plate to squeeze the water in the cylinder. As the water pressure gradually increases, it observes whether water seepage occurs on the bottom surface of the board. If water seepage occurs on the bottom surface of the board, the pressure value at this time is recorded. This pressure is the hydrostatic pressure of the board. The waterproofness of the board can be judged based on the hydrostatic pressure. The greater the hydrostatic pressure, the better the waterproofness of the board. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0047] Embodiment 1: As Figures 1 to 10 shown, an environmental protection building board quality determination device described in the present invention includes a waterproof detection device; the waterproof detection device includes a clamping assembly; the clamping assembly includes an upper clamping frame 1 and a lower clamping frame 11, and both the upper clamping frame 1 and the lower clamping frame 11 are in a square shape;

[0048] On the opposite side end faces of the upper clamping frame 1 and the lower clamping frame 11, opposite rectangular grooves 12 are opened, and the two rectangular grooves 12 are used for clamping the plate 16; rectangular sealing strips 13 are fixedly connected to the rectangular grooves 12 of the upper clamping frame 1 and the lower clamping frame 11;

[0049] Four drainage components are arranged around the rectangular sealing strip 13 in the upper clamp frame 1, and the drainage components are used to drain the water flowing to the side of the plate 16;

[0050] The four corners at the bottom of the lower clamping frame 11 are fixedly connected to the legs 14, and the other side of the legs 14 is installed on the workbench; the first hydraulic cylinder 15 is installed on both sides of the lower clamping frame 11 on the workbench; the two sides of the upper clamping frame 1 are fixedly connected to the mounting blocks, and the extension rod of the first hydraulic cylinder 15 is fixedly connected to the mounting blocks;

[0051] A cylinder 2 is provided on the top of the upper clamping frame 1, and the top of the cylinder 2 is closed and the bottom is open; a circular sealing strip 21 is fixedly connected to the bottom of the cylinder 2;

[0052] Both sides of the cylinder 2 are fixedly connected to the mounting plates; the lower surfaces of the two mounting plates are fixedly connected to the electric push rods 22, and the other side of the electric push rods 22 is fixedly connected to the upper surface of the upper clamping frame 1;

[0053] The top of the cylinder 2 is fixedly connected to a water pipe 23, and the water pipe 23 is connected to an external water source; a first piston plate 24 is provided in the cylinder 2, and leak holes 25 are evenly arranged on the first piston plate 24;

[0054] A guide pipe 26 is installed in the inner wall of the cylinder 2 above the circular sealing strip 21, and a control valve is installed in the guide pipe 26; a liquid pump 27 is fixedly connected to the outer surface of the cylinder 2, and the water inlet pipe 23 of the liquid pump 27 is connected to the guide pipe 26, and the water outlet pipe 23 of the liquid pump 27 extends to the outside of the upper clamp frame 1;

[0055] Specifically, when the sheet 16 is tested for waterproofness, the first hydraulic cylinder 15 is first controlled to extend, and the first hydraulic cylinder 15 will drive the upper clamping frame 1 to move upward, and the upper clamping frame 1 will drive the electric push rod 22 and the cylinder 2 to move upward. When the upper clamping frame 1 moves up to a certain height, the sheet 16 to be tested is placed in the rectangular groove 12 in the lower clamping frame 11. When the sheet 16 is placed in the rectangular groove 12 of the lower clamping frame 11, the sheet 16 will fit with the rectangular sealing strip 13 in the lower clamping frame 11, and then the first hydraulic cylinder 15 is controlled to contract, thereby driving the upper clamping frame 1 and the electric push rod 22 to move upward. 2 and the cylinder 2 move downward. As the upper clamp frame 1 gradually moves downward, the rectangular sealing strip 13 in the upper clamp frame 1 will gradually contact the upper surface of the plate 16. When the plate 16 contacts the rectangular sealing strip 13 in the upper clamp frame 1, the upper clamp frame 1 is controlled to move downward, so as to push the rectangular sealing strip 13 to squeeze the plate 16. When the upper clamp frame 1 is fitted with the lower clamp frame 11, the rectangular sealing strips 13 in the upper clamp frame 1 and the lower clamp frame 11 will squeeze the plate 16. Then the first hydraulic cylinder 15 is controlled to be pushed to contract, and then the plate 16 can be tested for waterproofness.

[0056] More specifically, when the plate 16 is tested for water spraying, the electric push rod 22 is first controlled to contract, and the contracted electric push rod 22 will drive the cylinder 2 and the circular sealing strip 21 on the cylinder 2 to move downward. When the circular sealing strip 21 is in contact with the top of the plate 16, the electric push rod 22 is controlled to stop working, and then the water source is introduced into the water pipe 23. The water flowing down from the water pipe 23 will fall on the first piston plate 24, and then the water on the first piston plate 24 will drip from the evenly arranged leakage holes 25, and the dripping water will fall on the plate 16, thereby simulating the scene of the plate 16 on a rainy day. The circular sealing strip 21 at the bottom is in contact with the plate 16, so when water drops onto the plate 16, the circular sealing strip 21 will block the water from flowing through the circular sealing strip 21, and at the same time, the liquid pump 27 is controlled to work, and the control valve in the guide tube 26 is opened. During the operation of the liquid pump 27, the water in the cylinder 2 can be pumped out, and the pumped water will be discharged to the outside. In this process, water accumulation in the cylinder 2 can be avoided, which makes it impossible to continue to simulate the scene of rain. When simulating rain, observe whether the plate 16 has water seepage, so as to detect the waterproofness of the plate 16 when it is raining;

[0057] Furthermore, when the plate 16 is tested for water storage, the control valve in the control guide tube 26 is closed, and the control liquid pump 27 is not operated, so the water falling on the plate 16 in the cylinder 2 will gradually increase until water accumulation occurs. When water accumulation occurs, the water accumulation on the plate 16 can be simulated, so that the waterproofness of the plate 16 when water is stored can be tested;

[0058] Furthermore, by utilizing the circular sealing strip 21, water can be prevented from flowing to the outside of the circular sealing strip 21 when the plate 16 is subjected to water sprinkling and water storage detection, thereby preventing water from flowing to the bottom of the plate 16 through the gap when there is a gap between the plate 16 and the upper clamp frame 1 and the lower clamp frame 11. If the staff does not discover it in time, they will think that the water on the plate 16 has penetrated the plate 16 and flowed to the bottom of the plate 16, which will mislead the staff and cause inaccurate detection results. At the same time, if the surface of some plates 16 is not smooth, part of the water will flow from under the circular sealing strip 21. At this time, the rectangular sealing strip 13 can first block this part of the water. If part of the water passes through the rectangular sealing strip 13, the exclusion component can discharge the water at this time, thereby preventing the water from passing through the gap between the plate 16 and the upper clamp frame 1 and the lower clamp frame 11 and flowing to the bottom of the plate 16.

[0059] Embodiment 2: The four removal components all include a transmission belt 3; the four side positions of the rectangular sealing strip 13 of the rectangular groove 12 in the upper clamp frame 1 are all provided with a transmission belt 3; the outer ring surfaces of the four transmission belts 3 are all fixedly connected with a water-absorbing cotton layer;

[0060] The four sides of the upper clamping frame 1 are provided with square grooves 31; one side of the four transmission belts 3 passes through the corresponding square grooves 31 and extends to the outside of the upper clamping frame 1, and the other side extends to the position of the adjacent transmission belt 3;

[0061] The four transmission belts 3 are rotatably connected on one side of the rectangular groove 12 through a rotating shaft; the transmission belt 3 extends to one side of the upper clamping frame 1 and is fixedly connected to two side plates 32 on the upper clamping frame 1;

[0062] A rotating rod is rotatably connected to the two side plates 32, and the transmission belt 3 rotates on the rotating rod; a first motor 33 is installed on the side plate 32, and the first motor 33 is used to drive the rotating rod;

[0063] In this embodiment, a squeezing roller 34 is rotatably connected between the two side plates 32 below the rotating rod, and the squeezing roller 34 is in contact with the water-absorbing cotton layer and is used to squeeze the water-absorbing cotton layer;

[0064] Specifically, if the surface of the plate 16 is not smooth, causing some water to flow through the gap between the rectangular sealing strip 13 and the plate 16, the first motor 33 is controlled to rotate, and the first motor 33 will drive the transmission belt 3 to rotate through the rotating rod. The rotating transmission belt 3 will drive the water-absorbing cotton layer to rotate. When water wants to pass through the water-absorbing cotton layer, the water-absorbing cotton layer will absorb this part of the water to prevent the water from continuing to flow. Since part of the transmission belt 3 extends to the outside, when the water-absorbing cotton layer follows the transmission belt 3 to rotate to the outside after absorbing water, the squeezing roller 34 will squeeze the water-absorbing cotton layer to squeeze out the water in the water-absorbing cotton layer. Subsequently, the water-absorbing cotton layer that squeezes out the water will circulate on the surface of the plate 16 and rotate, thereby continuously absorbing the water flowing through the transmission belt 3, thereby preventing water from flowing through the transmission belt 3 and flowing to the bottom of the plate 16.

[0065] Embodiment 3: A rectangular frame 17 is provided on the outer ring of the rectangular sealing strip 13 on the rectangular groove 12 in the lower clamping frame 11, and the rectangular frame 17 is fixedly connected in the rectangular groove 12;

[0066] The top end surface of the rectangular frame 17 is fixedly connected to the rectangular partition 18. When the plate 16 is placed in the rectangular groove 12, the rectangular partition 18 will fit with the bottom surface of the plate 16.

[0067] In this embodiment, the outer ring surface of the lower clamping frame 11 is fixedly connected to evenly arranged inclined tubes 19, and the inclined tubes 19 extend into the rectangular grooves 12 of the lower clamping frame 11;

[0068] Specifically, if part of the water flows to the bottom of the plate 16 through the transmission belt 3, the rectangular partition 18 attached to the plate 16 will continue to block the flow of water under the plate 16, and then the water will flow downward along the rectangular frame 17 and flow into the rectangular groove 12 of the lower clamping frame 11. In this process, the water can be further blocked from continuing to flow, thereby preventing the water from flowing to the bottom of the plate 16.

[0069] More specifically, when water flows into the rectangular groove 12 , the inclined tube 19 fixedly connected to the outer ring surface of the lower clamp frame 11 extends into the rectangular groove 12 , so the water in the rectangular groove 12 will be discharged through the inclined tube 19 , thereby avoiding excessive water accumulation in the rectangular groove 12 .

[0070] Embodiment 4: A plurality of mutually surrounding circular frames 4 are provided below the lower clamping frame 11. When the plate 16 is placed in the rectangular groove 12, the circular frames 4 are in contact with the bottom surface of the plate 16;

[0071] The bottom end surfaces of the plurality of circular frames 4 are fixedly connected to uniformly arranged connecting plates 41; each connecting plate 41 is fixedly connected to an L-shaped plate 42, and the L-shaped plates 42 extend to the bottom of the lower clamping frame 11; the L-shaped plates 42 are fixedly connected to the lower clamping frame 11 by locking bolts;

[0072] In this embodiment, the adjacent circular frames 4 are fixedly connected with color-changing water writing paper 43. When the plate 16 is placed in the rectangular groove 12, the color-changing water writing paper 43 is in contact with the bottom surface of the plate 16.

[0073] Specifically, since the bottom surface of the plate 16 is in contact with the plurality of circular frames 4, when water penetrates from the plate 16 to the bottom of the plate 16, the circular frames 4 can block the water and prevent the water from flowing on the bottom plate, so that the specific position of the water seepage at the bottom of the plate 16 cannot be known;

[0074] More specifically, since the circular frame 4 is provided with a color-changing water writing paper 43 , when water penetrates to the bottom of the plate 16 , it will contact the color-changing water writing paper 43 , causing the color-changing water writing paper 43 to change color, so that the staff can quickly observe the situation and position of water seepage of the plate 16 .

[0075] Embodiment 5: The top of the cylinder 2 is fixedly connected to the second hydraulic cylinder 5, and the extension rod of the second hydraulic cylinder 5 extends into the cylinder 2 and is fixedly connected to the top of the first piston plate 24; the second hydraulic cylinder 5 is provided with a pressure sensor;

[0076] A second piston plate 51 is provided on the top of the first piston plate 24, and the extension rod of the second hydraulic cylinder 5 passes through the second piston plate 51 and is rotatably connected to the second piston plate 51;

[0077] The extension rod of the second piston plate 51 is fixedly connected to a retaining ring 52, and the retaining ring 52 is in contact with the top of the second piston plate 51; the second piston plate 51 is also provided with leak holes 25 that are evenly arranged, and in an initial state, the leak holes 25 on the second piston plate 51 overlap with the leak holes 25 on the first piston plate 24;

[0078] The top of the second piston plate 51 is fixedly connected to the gear teeth 53 which are evenly arranged; the top of the cylinder 2 is fixedly connected to the second motor 54; the rotating shaft of the second motor 54 is fixedly connected to the gear 55, and the gear 55 partially extends into the cylinder 2 and meshes with the gear teeth 53;

[0079] Specifically, when testing some plates 16 with smooth surfaces, not only can the plates 16 be sprayed with water and stored with water be tested, but also the smooth plates 16 can be subjected to a hydrostatic pressure test. First, the circular sealing strip 21 is controlled to fit the surface of the plate 16, and then water is introduced into the cylinder 2 through the water pipe 23, and at the same time, the control valve in the guide pipe 26 is closed. Since the leakage holes 25 on the first piston plate 24 and the second piston plate 51 overlap with each other, water will flow downward through the leakage holes 25. As the amount of water flowing into the cylinder 2 gradually increases, the liquid level of the water in the cylinder 2 gradually increases. When the liquid level in the cylinder 2 is above the first piston plate 24, the introduction of water is stopped at this time. Then, the second motor 54 is controlled to drive the gear 55 to rotate, and the gear 55 will drive the gear 53 to rotate. The rotating gear 53 will drive the second piston plate 51 to rotate. When the leakage hole 25 on the second piston plate 51 is misaligned with the leakage hole 25 on the first piston plate 24, the second motor 54 is controlled to stop rotating.

[0080] More specifically, the second hydraulic cylinder 5 is then controlled to extend, the second hydraulic cylinder 5 will drive the first piston plate 24 to move downward, and at the same time will drive the second piston plate 51 to move downward through the retaining ring 52. The downwardly moving first piston plate 24 will squeeze the water. As the first piston plate 24 continues to move downward, the water pressure in the cylinder 2 will gradually increase, and the pressure sensor will record the pressure. At the same time, the water pressure will act on the plate 16. As the water pressure gradually increases, observe whether there is water seepage on the bottom surface of the plate 16. If water seepage occurs on the bottom surface of the plate 16, record the pressure value at this time. This pressure is the hydrostatic pressure of the plate 16. The waterproofness of the plate 16 can be judged based on the hydrostatic pressure. The greater the hydrostatic pressure, the better the waterproofness of the plate 16.
