Description

Technical Field

[0001] This invention relates to the field of building material waterproofing testing technology, specifically a device for testing the waterproofing performance of building materials. Background Technology

[0002] Building materials are a general term for materials used in civil engineering and construction projects. They can be divided into structural materials, decorative materials, and certain special materials. Structural materials include wood, bamboo, stone, cement, concrete, metal, bricks, ceramics, glass, engineering plastics, composite materials, etc. Decorative materials include various coatings, paints, platings, veneers, colored tiles, and glass with special effects, etc. Waterproof membranes, as a type of structural building material, are widely used in waterproofing projects on the top floor of buildings. During the production and use of waterproof membranes, it is necessary to test their waterproof performance.

[0003] A search revealed a weighted double-sided waterproof membrane impermeability tester (publication number CN103091216A) on the China Patent Network. The tester consists of a balance sleeve at each of the four corners of the upper part of the support frame, a cylindrical pressure seat mounted on the support frame, and a piston cylinder mounted on the top of the cylindrical pressure seat. One side wall of the piston cylinder has a small hole connecting the inside and outside of the cylinder. A balance rod is located at each of the four corners of the bottom of the load plate, with the diameter of the balance rod being smaller than the inner diameter of the balance sleeve. A piston, matching the piston cylinder, is located at the geometric center of the bottom of the load plate. The balance rods, balance sleeves, pistons, and piston cylinders are all positioned in a one-to-one correspondence.

[0004] However, during use, such devices have poor sealing performance for waterproof membranes, which can easily lead to water seepage and leakage at the sealing edges. This affects the accuracy of waterproof performance testing and can easily cause false detections due to leakage.

[0024] Please see Figures 1-5 In this embodiment of the invention, a building material waterproof performance testing device includes two sets of guide rail frames 1. The upper half of the guide rail frame 1 is symmetrically fitted with a lower pressure sliding sleeve 2, and the lower half of the guide rail frame 1 is symmetrically fitted with an upper pressure sliding sleeve 3. The lower pressure sliding sleeve 2 and the upper pressure sliding sleeve 3 are connected by a mating mechanism 4. The mating mechanism 4 includes a mating hydraulic cylinder 41. The upper and lower ends of the mating hydraulic cylinder 41 are symmetrically connected with two sets of fixed seats 42. There are two sets of mating hydraulic cylinders 41, and the two sets of mating hydraulic cylinders 41 are arranged symmetrically in opposite directions. When testing the waterproof performance of the waterproof membrane, the worker cuts the waterproof membrane into a circular structure of the same size as the upper pressure ring seat 8. After cutting, the circular piece is placed on the upper pressure ring seat 8, and then the telescopic ends of the two sets of mating hydraulic cylinders 41 begin to retract, pulling the lower pressure sliding sleeve 2 downward, so that the lower pressure ring seat 6 and the upper pressure ring seat 8 are mated, and the circular waterproof membrane is pressed and sealed.

[0025] The fixed base 42 is connected to the coupling hydraulic cylinder 41 via the coupling guide rod 43. A pressure spring 44 is sleeved on the outer side of the coupling guide rod 43, and a negative pressure suction block 45 is provided at the bottom end of the coupling guide rod 43. A negative pressure pipe 46 is inserted through the inner side of the fixed base 42 at the bottom end. A negative pressure guide rod 47 is inserted and engaged through the inner side of the negative pressure pipe 46. A compression spring 48 is sleeved on the outer side of the negative pressure guide rod 47, and a negative pressure plug 49 is provided at the bottom end of the negative pressure guide rod 47. The coupling guide rod 43 is elastically engaged with the fixed base 42 via the pressure spring 44, and the negative pressure guide rod 47 is elastically engaged with the negative pressure pipe 46 via the compression spring 48. During the contraction and extension of the two sets of coupling hydraulic cylinders 41, the tension generated by the contraction is transmitted to… On the mating guide rod 43, the mating hydraulic cylinder 41 is kept in elastic contraction by the elastic engagement of the compression spring 44 with the mating guide rod 43. During the extension and retraction of the mating guide rod 43, the negative pressure suction block 45 at its bottom is displaced synchronously, so that the chamber of the fixed seat 42 forms a negative pressure state. This, together with the elastic mechanical strain of the compression spring 44, forms a double elastic tension of air pressure and mechanical force, so that the lower pressure ring seat 6 and the upper pressure ring seat 8 are kept in elastic engagement. After the mating test is completed, when the extension and retraction end of the mating hydraulic cylinder 41 extends and resets, the negative pressure suction block 45 resets and moves. Through the elastic combination of the negative pressure guide rod 47 and the compression spring 48, the negative pressure gas is pushed out through the negative pressure plug 49, reducing the thrust generated by the reset movement of the mating hydraulic cylinder 41.

[0026] A lower pressure plate frame 5 is fixed to the inner side of the lower pressure sliding sleeve 2, and an upper pressure plate frame 7 is fixed to the inner side of the upper pressure sliding sleeve 3. Both the mating ends of the lower pressure plate frame 5 and the upper pressure plate frame 7 are equipped with sealing detection components. The sealing detection components include a lower pressure ring seat 6 located below the lower pressure plate frame 5 and an upper pressure ring seat 8 located above the upper pressure plate frame 7. A high-pressure water pipe 10 is connected to the bottom of the upper pressure ring seat 8, and a water accumulation chamber 12 is spaced inside the upper pressure ring seat 8. A deformation airbag A11 is wrapped around the upper pressure ring seat 8, and the inner side of the upper pressure ring seat 8 is directly opposite the deformation airbag A11. The lower part of the upper pressure ring seat 8 is fitted with an upper pressure ring frame 14. An upper pressure magnetic ring A15 is located at the bottom of the upper pressure ring frame 14. An upper pressure magnetic ring B16 is located below the upper pressure magnetic ring A15 on the inner side of the upper pressure ring seat 8. A deformation airbag B17 is wrapped around the lower part of the lower pressure ring seat 6. An upper pressure ring frame 21 is fitted with an upper pressure ring 21 above the deformation airbag B17 on the inner side of the upper pressure ring seat 8. A lower pressure magnetic ring B20 is located at the top of the upper pressure ring frame 21. A lower pressure magnetic ring A19 is located above the lower pressure magnetic ring B20 on the inner side of the upper pressure ring frame 21. A sealing groove 13 is provided on the upper end face of the upper pressure ring 14. An upper pressure seat 22 is provided below the upper pressure ring frame 21. The upper pressure ring frame 14 and the upper pressure ring frame 21 are sealed and engaged through the sealing groove 13 and the upper pressure seat 22. The upper pressure magnetic ring A15, upper pressure magnetic ring B16, lower pressure magnetic ring A19, and lower pressure magnetic ring B20 are all made of neodymium magnets. The magnetic repulsion between the upper pressure magnetic ring A15 and the upper pressure magnetic ring B16 is the same as that between the lower pressure magnetic ring A19 and the lower pressure magnetic ring B20. During the engagement of the lower pressure ring seat 6 and the upper pressure ring seat 8, when the lower pressure ring seat 6 and the upper pressure ring seat 8 are engaged, the magnetic repulsion between the lower pressure ring seat 6 and the upper pressure ring seat 8 is the same. When the pressure ring seats 8 are in contact with each other, the deformation airbags A11 and B17 are squeezed and expanded to deform, sealing the upper and lower ends of the waterproof membrane. During the continuous contact process, the upper pressure seat 22 and the sealing groove 13 are in contact with each other. Under the magnetic repulsion of the two sets of upper pressure magnetic rings and the two sets of lower pressure magnetic rings, they maintain elastic contact, and seal the contact end of the deformation airbag and the waterproof membrane again to ensure the sealing of the end of the waterproof membrane. When the lower pressure ring seat 6 and the upper pressure ring seat 8 are in contact with each other, the sealing of the waterproof membrane is completed.

[0027] A leakage sensing and detection mechanism 18 is installed inside the cavity of the lower pressure ring seat 6. The output end of the leakage sensing and detection mechanism 18 is connected to the rotary motor 9. The leakage sensing and detection mechanism 18 includes a support seat 181, a drive shaft 182 is installed above the support seat 181, and a stop baffle 183 is installed below the support seat 181. Two sets of rotating brackets 184 are symmetrically arranged on both sides of the support seat 181. A telescopic guide rod 185 is inserted and engaged below the rotating bracket 184. A pressure-reducing spring 186 is sleeved on the outside of the telescopic guide rod 185, and a leakage sensing probe 187 is installed at the bottom end of the telescopic guide rod 185. There are two sets of leakage sensing probes 187, one set with four probes and the other set with five probes. The two sets of leakage sensing probes 187 are arranged at intervals and staggered. After the waterproof membrane is sealed, high-pressure water is input to the upper pressure ring through the high-pressure water pipe 10. Inside the water-accumulating chamber 12 of seat 8, high-pressure water permeates upwards through the waterproof membrane under pressure. Simultaneously, the stop baffle 183 presses down on the center end face of the waterproof membrane to prevent excessive deformation under water pressure. The leakage sensor probe 187, elastically pressed against the detection surface of the waterproof membrane by the elastic combination of the telescopic guide rod 185 and the pressure-reducing spring 186, allows the leakage sensor probe 187 to detect various positions on the detection surface of the waterproof membrane. Then, the rotary motor 9 starts working, driving the transmission shaft 182 to rotate, which in turn drives the support seat 181 to rotate, causing the two sets of rotating brackets 184 to start rotating. During the rotation of the rotating brackets 184, the leakage sensor probe 187 is pushed to perform rotational detection on the detection surface of the waterproof membrane, so as to detect and sense the seepage points in a timely and comprehensive manner.

[0028] The working principle of this invention is as follows: When testing the waterproof performance of the waterproof membrane, the worker cuts the waterproof membrane into circular pieces of the same size as the upper pressure ring seat 8. After cutting, the circular pieces are placed on the upper pressure ring seat 8. Then, the telescopic ends of the two sets of engaging hydraulic cylinders 41 begin to retract, pulling the lower pressure sleeve 2 downward, so that the lower pressure ring seat 6 and the upper pressure ring seat 8 are engaged, thus pressing and sealing the circular waterproof membrane. During the retraction of the telescopic ends of the two sets of engaging hydraulic cylinders 41, the tension generated by the retraction is transmitted to the engaging guide rod 43, and the elastic engagement of the pressure spring 44 and the engaging guide rod 43 is achieved. This allows the hydraulic cylinder 41 to maintain elastic contraction, and during the extension and retraction of the guide rod 43, the negative pressure suction block 45 at its bottom moves synchronously, creating a negative pressure state in the chamber of the fixed seat 42. This, combined with the elastic mechanical strain of the compression spring 44, forms a dual elastic tension of air pressure and mechanical force, keeping the lower pressure ring seat 6 and the upper pressure ring seat 8 in elastic engagement. Furthermore, during the engagement process of the lower pressure ring seat 6 and the upper pressure ring seat 8, when the lower pressure ring seat 6 and the upper pressure ring seat 8 are in close contact, the deformation airbags A11 and B17 compress and expand, performing a film sealing treatment on the upper and lower end faces of the waterproof membrane. And during the continuous engagement process... The upper pressure seat 22 and the sealing groove 13 engage with each other. Under the magnetic repulsion of the two sets of upper pressure magnetic rings and the two sets of lower pressure magnetic rings, they maintain elastic engagement, thus resealing the bonding end face of the deformable airbag and the waterproof membrane. When the lower pressure ring seat 6 and the upper pressure ring seat 8 engage and abut with each other, the sealing of the waterproof membrane is completed. After the waterproof membrane is sealed, high-pressure water is introduced into the water accumulation chamber 12 inside the upper pressure ring seat 8 through the high-pressure water pipe 10. Under pressure, the high-pressure water in the water accumulation chamber 12 permeates upward into the waterproof membrane, and the stop baffle 183 simultaneously presses against the center end of the waterproof membrane. The surface is pressed down to prevent excessive deformation of the waterproof membrane under water pressure. The leakage sensor probe 187, under the elastic combination of the telescopic guide rod 185 and the pressure-reducing spring 186, elastically presses against the waterproof membrane detection surface, enabling the leakage sensor probe 187 to detect various positions on the waterproof membrane detection surface. Then, the rotary motor 9 starts working, driving the transmission shaft 182 to rotate, and at the same time driving the support base 181 to rotate, causing the two sets of rotating brackets 184 to start rotating. During the rotation of the rotating brackets 184, the leakage sensor probe 187 is pushed to perform rotational detection on the waterproof membrane detection surface.
