Description

Technical Field

[0001] This utility model relates to the field of building material testing technology, specifically a testing fixture for building waterproofing materials. Background Technology

[0002] Waterproofing materials are a general term for materials that prevent seepage, leakage, and erosion. Building envelopes must effectively prevent the seepage of rainwater, snowmelt, and groundwater, as well as prevent the erosion of moisture, steam, and other harmful gases and liquids in the air. Building partitions must prevent the seepage of water supply and drainage. Therefore, waterproofing materials need to be tested for their performance before use, and testing fixtures are needed to fix them during the testing process.

[0003] For example, the patent with authorization announcement number CN221160049U describes a building waterproof material testing fixture. However, when testing other surfaces of the building waterproof material, the fixture requires disassembling the building waterproof material, flipping it over, and then fixing it for testing. It cannot rotate the material for testing, making the operation relatively cumbersome. Furthermore, when clamping flexible waterproof material, the second screw can interfere with the material's position, making it unsuitable for waterproof materials of different sizes and reducing its practicality.

[0004] Based on this, a testing fixture for building waterproofing materials is now provided, which can eliminate the drawbacks of existing technical solutions. Utility Model Content

[0005] The purpose of this utility model is to provide a building waterproof material testing fixture to solve the problems of cumbersome flipping testing operation and inability to adapt to materials of different sizes in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A building waterproofing material testing fixture includes a base, a groove on the upper surface of the base, a bidirectional lead screw rotatably mounted inside the groove, one end of the bidirectional lead screw extending to the outside of the base and fixedly connected to the output end of a drive motor, and sliding plates threaded to both ends of the bidirectional lead screw, the sliding plates being slidably connected to the groove, and a waterproof plate being provided between the two sliding plates.

[0008] The top of the base is provided with a fixing mechanism for limiting and flipping the waterproof membrane, and the bottom of the waterproof membrane is provided with a support mechanism for supporting the middle part of the waterproof membrane.

[0009] The fixing mechanism includes mounting plates symmetrically arranged between two slide plates. The mounting plates are rotatably connected to the slide plates via rotating shafts, and the rotating shafts extend to the outside of the slide plates. One end of the rotating shaft is fixedly connected to the output end of a rotary motor, and the other end of the rotating shaft is connected to a locking assembly. A clamping assembly for limiting the waterproof membrane is provided on one side of the two mounting plates opposite to each other.

[0010] Preferably, the locking assembly includes a gear, the upper end of which is engaged with a rack block, a fixing block is disposed above the rack block, the fixing block is fixedly installed on the corresponding slide plate, a bracket is movably connected inside the fixing block, the bottom of the bracket is fixedly connected to the rack block, and a spring is disposed between the fixing block and the bracket.

[0011] Preferably, the clamping assembly includes clamping plates symmetrically arranged on the surface of the mounting plate, a stud threadedly connected to the middle of the clamping plate, a pressure plate rotatably disposed at the bottom end of the stud, the pressure plate being disposed between the two clamping plates, and guide rods symmetrically mounted on the upper surface of the pressure plate, with the upper clamping plate slidably connected to the guide rods.

[0012] Preferably, the support mechanism includes placement slots symmetrically opened on both sides of the slide groove. One of the placement slots is rotatably provided with a threaded sleeve, and a screw is threadedly connected to the inside of the threaded sleeve. A support plate is fixedly connected to the end of the screw. The other placement slot is fixedly provided with a telescopic rod, the top of which is fixedly connected to the support plate. A turntable is fixedly provided at the bottom of the threaded sleeve, and the turntable is connected to the bottom wall of the placement slot through a pin.

[0013] Preferably, a controller is provided on one side of the base.

[0014] Preferably, the support plate is configured as an I-shaped structure.

[0015] Preferably, one side of the slide is provided with a groove, and the groove is adapted to the shape of the support plate.

[0016] Preferably, the support plate and the pressure plate are both provided with rubber pads on the side near the waterproof plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This building waterproofing material testing fixture, through the setting of a fixing mechanism and a support mechanism, achieves rapid flipping and stable support of waterproofing materials, significantly improving testing efficiency and avoiding the tedious operation of repeated disassembly and re-fixing. The combination of a two-way lead screw and a sliding plate allows it to adapt to waterproofing materials of different sizes, enhancing the fixture's versatility and practicality. Rubber pads effectively protect the surface of the waterproofing membrane, preventing material damage during clamping. The I-shaped support plate and telescopic rod design of the support mechanism further enhance testing stability and prevents the waterproofing membrane from being unable to taut due to a lack of support at the bottom center after clamping, even if the membrane is too large or too soft, thus avoiding affecting testing accuracy.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] Example 1

[0029] In this embodiment, as Figures 1-7 As shown, a building waterproof material testing fixture includes a base 101. A groove 102 is provided on the upper surface of the base 101. A bidirectional lead screw 103 is rotatably provided inside the groove 102. One end of the bidirectional lead screw 103 extends to the outside of the base 101 and is fixedly connected to the output end of a drive motor. Both the drive motor and the rotary motor are waterproof motors. Both ends of the bidirectional lead screw 103 are threadedly connected to sliding plates 104. The sliding plates 104 are slidably connected to the groove 102. The surfaces of the bidirectional lead screw 103, stud 207, threaded sleeve 302, and screw 303 are all coated with waterproof coating to avoid affecting the waterproof testing operation and extend the fixture's life. A waterproof plate 105 is provided between the two sliding plates 104.

[0030] The top of the base 101 is provided with a fixing mechanism 200 for limiting and flipping the waterproof plate 105, and the bottom of the waterproof plate 105 is provided with a support mechanism 300 for supporting the middle part of the waterproof plate 105. Before the clamp is used, check whether the clamp can be used normally, and then adjust the fixing mechanism 200 and the support mechanism 300 to make it ready for use.

[0031] The fixing mechanism 200 includes mounting plates 201 symmetrically arranged between two slide plates 104. The surface of the slide plate 104 is marked with scales to facilitate quick understanding of the flip angle of the mounting plate 201 and improve detection accuracy. The mounting plates 201 are rotatably connected to the slide plates 104 via rotating shafts, and the rotating shafts extend to the outside of the slide plates 104. The end of one rotating shaft is fixedly connected to the output end of a rotary motor, and the end of the other rotating shaft is connected to a locking component. A clamping component for limiting the waterproof plate 105 is provided on one side opposite to the two mounting plates 201. The rotating shafts are driven by the rotary motor, and in conjunction with the fixed waterproof plate 105, the mounting plates 201 and clamping components on both sides are rotated, thereby realizing the overall flipping operation of the waterproof plate 105.

[0032] Among them, such as Figures 2-7As shown, the locking assembly includes a gear 202, with a rack block 203 meshing at its upper end. A fixing block 204 is positioned above the rack block 203. Through the meshing of the gear 202 and the rack block 203, the positions of the mounting plates 201 on both sides and the clamping assembly correspond during the clamping of the waterproof membrane 105, facilitating stable placement of the waterproof material and ensuring its fixed position after flipping. The fixing block 204 is fixedly mounted on the corresponding sliding plate 104, and a bracket 205 is movably connected inside the fixing block 204. The surface of the slide plate 104 has a small hole. The user can manually lift the bracket 205 and fix the position of the bracket 205 by using a pin, bolt or other component, so that the gear 202 and the rack block 203 can be separated, which facilitates the flipping operation. The bottom of the bracket 205 is fixedly connected to the rack block 203. A spring is provided between the fixing block 204 and the bracket 205. The two ends of the spring are fixed to the fixing block 204 and the bracket 205 respectively, so as to provide a restoring force to maintain the stable meshing state of the gear 202 and the rack block 203.

[0033] Among them, such as Figures 2-5 As shown, the clamping assembly includes clamping plates 206 symmetrically arranged on the surface of the mounting plate 201. A stud 207 is threadedly connected to the middle of the clamping plate 206. A pressure plate 208 is rotatably arranged at the bottom end of the stud 207. The pressure plate 208 is arranged between the two clamping plates 206. A connecting block is provided on one side of the pressure plate 208. The connecting block can be connected to the clamping plate 206 located below by several bolts to increase the clamping effect on the waterproof membrane 105. Guide rods 209 are symmetrically installed on the upper surface of the pressure plate 208. The clamping plate 206 located above is slidably connected to the guide rods 209. By rotating the stud 207, the pressure plate 208 is driven to move up and down. In conjunction with the up and down sliding of the guide rods 209, the clamping or loosening effect on the waterproof membrane 105 is achieved.

[0034] Among them, such as Figures 1-5 As shown, the support mechanism 300 includes placement slots 301 symmetrically opened on both sides of the slide groove 102. One placement slot 301 has a threaded sleeve 302 rotatably installed inside, and a screw 303 is threadedly connected inside the threaded sleeve 302. A support plate 304 is fixedly connected to the end of the screw 303. By rotating the turntable 306, the threaded sleeve 302 is driven to rotate, which in turn drives the screw 303 to move up and down, thereby adjusting the height of the support plate 304. In conjunction with the telescopic rod 305, the telescopic rod 305 is extended and retracted to support the middle part of the waterproof membrane 105, ensuring that the material does not deform during the testing process. The other placement slot 301 has a telescopic rod 305 fixedly installed inside, and the top of the telescopic rod 305 is fixedly connected to the support plate 304. A turntable 306 is fixedly installed at the bottom of the threaded sleeve 302. The turntable 306 is connected to the bottom wall of the placement slot 301 through a pin to facilitate fixing the position of the threaded sleeve 302.

[0035] Among them, such as Figure 1As shown, a controller 106 is provided on one side of the base 101. The controller 106 is electrically connected to the electrical components of the fixture to facilitate the output of commands.

[0036] Example 2

[0037] The difference from Example 1 is that, as in Example 1, Figure 2 and Figure 4 As shown, the support plate 304 is designed with an I-shaped structure, so that when the support plate 304 is lowered to the lowest position, it can be flush with the upper surface of the base 101, which makes it easy to store and reduces the space occupied.

[0038] Among them, such as Figure 5 As shown, a groove 107 is provided on one side of the slide 102. The groove 107 is adapted to the shape of the support plate 304, which facilitates the placement of the support plate 304 and increases the overall practicality.

[0039] Among them, such as Figure 2 and Figure 3 As shown, rubber pads are provided on the side of the support plate 304 and the pressure plate 208 near the waterproof plate 105 to prevent material damage.

[0040] In use, the drive motor is started to rotate the bidirectional lead screw 103, causing the two slide plates 104 to move synchronously in opposite directions along the slide groove 102, thereby adjusting the clamping distance to accommodate waterproof sheets 105 of different widths. The rotating stud 207 then pushes the pressure plate 208 down, pressing the waterproof sheet 105 between the clamping plates 206. When flipping for inspection is required, the locking component is first unlocked, and the bracket 205 is manually lifted upwards to disengage the rack block 203 from the gear 202, releasing the locking state of the corresponding rotating shaft. Then, the rotary motor is started to rotate the rotating shaft, causing the mounting plate 201 and the clamped waterproof sheet 105 to flip as a whole. After flipping to the correct position, the bracket 205 is released, and the spring pushes the rack block 203 to re-engage the gear 202, locking the position for subsequent inspection operations.

[0041] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
