Description

Technical Field

[0001] This invention relates to the field of building material testing technology, and in particular to a device for testing the impermeability of building construction materials. Background Technology

[0002] In the field of building construction and civil engineering quality control, the impermeability of materials is one of the key indicators for measuring their durability and structural safety. For structures such as dams, tunnels, basements, bridges, and the foundations and exterior walls of high-rise buildings that are constantly exposed to water or humid environments, the impermeability of materials directly determines the service life and operational safety of the project. If the impermeability of building materials fails to meet standards, it will not only reduce the service performance of the structure but may also lead to serious engineering accidents such as leakage, steel corrosion, concrete freeze-thaw damage, and even structural instability, causing huge economic losses and safety hazards. Therefore, accurate and reliable impermeability testing of building construction materials is an indispensable core link in the inspection of incoming materials, quality control, and durability assessment.

[0003] Currently, while existing material permeability testing devices and methods meet basic testing needs to a certain extent, they still have many technical limitations in practical applications. Traditional testing methods, such as the permeability labeling method and the permeability height method, often employ a single-sample or small-sample sequential testing approach. When multiple sets of experimental data are needed or parallel control experiments are required, operators must repeatedly perform steps such as sample loading, pressurization, observation, and recording. This approach not only leads to low testing efficiency but also makes it difficult to ensure a high degree of consistency in environmental conditions between multiple experiments. Subtle differences in experimental environmental conditions directly affect the accuracy of permeability results, resulting in poor comparability of data obtained from multiple batches of tests, making it difficult to meet the requirements of modern engineering testing for experimental professionalism and data rigor.

[0004] Taking concrete permeability analyzers widely used in current engineering projects as an example, although some devices can simultaneously install six specimens for testing, their sealing methods mostly involve manual heat-sealing using materials such as paraffin and rosin. This sealing method is cumbersome, time-consuming, and the sealing effect heavily depends on the operator's skill level, making it highly susceptible to human error. In actual testing, water seepage around the specimens frequently occurs due to inadequate sealing, rendering the test data of a single specimen invalid and even affecting the progress of the entire batch of experiments.

[0005] Furthermore, existing testing devices have significant shortcomings in terms of stability and adaptability during the testing process. On the one hand, when placing the material to be tested on the testing platform, the device often lacks effective positioning, buffering, and locking structures. The specimen is prone to positional shifts during placement, or uneven stress distribution can lead to inconsistent initial stress states, thus introducing testing errors. On the other hand, the sealing connection method between the testing unit and the specimen is relatively simple, making it difficult to adapt to building materials of different thicknesses, sizes, or surface conditions. The versatility and adaptability of the device need to be improved.

[0006] More importantly, in existing multi-sample synchronous testing processes, if a single sample ruptures or fails to seal under high pressure, causing a momentary pressure leak, it often leads to significant pressure fluctuations or instantaneous loss in the entire hydraulic system, forcing the ongoing experiment to be interrupted. This problem of "single-point failure affecting the whole" severely restricts the device's risk resistance and experimental success rate, especially during long-term pressure holding or critical comparative tests, where the risk is particularly prominent.

[0007] The present invention aims to solve the technical problems existing in the prior art. To this end, a waterproofing testing device for building construction materials is proposed. Summary of the Invention

[0018] As a further embodiment of the present invention: transmission gear rings are symmetrically arranged on the outer sides of both ends of the internal thread transmission cylinder, and several adjusting drive components are arranged at equal angles on the upper end of the drive mounting cylinder.

[0020] As a further embodiment of the present invention: a limiting shaft is provided at the lower end of the lifting threaded column, and a limiting bearing sleeve is provided on the upper side of the synchronous piston disc in conjunction with the limiting shaft;

[0021] As a further aspect of the present invention: the independent detection unit includes a wide-diameter hydraulic cylinder connected to the lower side of the synchronous hydraulic cylinder, a detection piston disc is provided inside the wide-diameter hydraulic cylinder, and a reduced-diameter detection cylinder is provided at the lower end of each wide-diameter hydraulic cylinder.

[0022] As a further embodiment of the present invention: an anti-deviation guide cylinder is provided on the upper side of the detection piston disc, and an anti-deviation guide post is provided in conjunction with the anti-deviation guide cylinder, with the upper end of the anti-deviation guide post fixed on the lower side of the synchronous piston disc.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. High detection stability and reliability:

[0026] The anti-slip texture on components such as the support pad and support mounting plate ensures that the entire device remains stable and does not slide during the testing process.

[0027] The loading and mounting tray is equipped with anti-slip textures and an anti-slip rubber layer, which effectively prevents construction materials from shifting during testing, ensures uniform force distribution, and reduces testing errors caused by unstable placement.

[0028] By utilizing the combination of reset rubber columns and annular air cushions, when building construction materials are placed, the loading and mounting plate can adaptively move downwards and be locked in place by the annular air cushion to support the pad, thus achieving automatic and stable locking after the building construction materials are placed and ensuring positional accuracy during the detection process.

[0029] 2. High efficiency and strong data comparability in synchronous detection:

[0030] The device contains multiple sets of synchronous detection modules, which can simultaneously perform impermeability testing on multiple building materials or multiple points on a single building material. Multiple sets of data can be obtained in a single experiment, which significantly improves the detection efficiency.

[0031] Because multiple tests are conducted simultaneously, the environmental conditions such as pressure, temperature, and humidity of all building materials are highly consistent. Whether conducting parallel or control tests, this significantly improves the professionalism and comparability of the experimental data.

[0032] 3. High detection accuracy and precise control:

[0033] Through the precise coordination of the lifting threaded column, synchronous piston disc, and hydraulic transmission, the seepage pressure applied to building materials can be accurately controlled and pressure can be maintained, thereby accurately simulating seepage resistance conditions.

[0034] The compression sealing ring at the lower end of the reduced diameter testing cylinder can form a good seal when in contact with building materials, preventing leakage of permeate and ensuring the accuracy of the test results.

[0035] The sponge disc has seepage guide holes, which, together with the squeezing action, can make the experimental permeate evenly cover the surface of the building construction materials.

[0036] 4. Easy to operate and highly adaptable:

[0037] The angle of multiple synchronous detection modules can be adjusted by the adjustment module, providing ample operating space for the placement and removal of building construction materials, making it very convenient to use.

[0038] The adjustable telescopic column can change the spacing between the detection module and the building construction materials to accommodate building construction materials of different thicknesses or sizes.

[0039] The sponge disc can absorb the same or different experimental permeate solutions according to different types of permeability testing, thus meeting diverse experimental needs.

[0040] 5. Strong resistance to risks and interference:

[0041] When the building materials in one independent testing unit crack or lose pressure, the pressure in other testing units will not be lost immediately due to the design of the anti-deviation guiding structure. Normal testing can be restored with only a short period of pressure replenishment, avoiding the failure of the entire experiment due to a single point of failure. This greatly enhances the device's anti-interference capability and the success rate of the experiment. Attached Figure Description

Detailed Implementation

[0054] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0055] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0056] Example 1, please refer to Figures 1-5 In this embodiment of the invention, a waterproofing testing device for building construction materials includes a support mounting base 1, a support mounting plate 19 disposed on one side of the support mounting base 1, and the support mounting plate 19 and the support mounting base 1 connected by a support mounting plate 15. The device also includes:

[0057] The loading mounting plate 12 is provided above the support mounting plate 19. The loading mounting plate 12 is connected to the support mounting base 1 through the loading mounting plate 13. The loading mounting plate 13 is provided with reset rubber columns 14 in series. The upper side of the loading mounting plate 12 is provided with loading anti-slip texture 20. The loading anti-slip texture 20 is covered with an anti-slip rubber layer 21. Several annular air cushions 22 are concentrically provided on the lower side of the loading mounting plate 12.

[0058] The outer side of the support mounting plate 19 is provided with a number of support pads 16 at equal angles to the loading mounting plate 12. The lower ends of the support pads 16, the support mounting plate 19, the support mounting plate 15, and the support mounting base 1 are all provided with support anti-slip textures 17.

[0059] The adjustment and synchronization detection mechanism includes an adjustment module and multiple sets of synchronization detection modules.

[0060] By placing the device at the target position, the anti-slip texture 17 on the support pad 16, support mounting plate 19, support mounting plate 15, and support mounting base 1 comes into contact with the ground, making the device stable and preventing it from sliding.

[0061] The construction materials to be tested are then placed on top of the device mounting plate. At this time, the weight of the construction materials causes the reset rubber column 14 to deform, causing the loading mounting plate 12 on one side to move toward the support mounting plate 19 until several annular air cushions 22 on it come into contact with the support pad 16. The deformed annular air cushions 22 jam the support pad 16, restricting the movement of the loading mounting plate 12 and ensuring the stability of the loading mounting plate 12 during the testing process.

[0062] Because the loading and mounting plate 12 is provided with loading anti-slip texture 20, and the loading anti-slip texture 20 is provided with anti-slip rubber layer 21, the construction materials placed on the loading and mounting plate 12 are difficult to shift and are evenly stressed, resulting in small deformation during testing, and at the same time, it does not affect the penetration testing of construction materials.

[0063] Specifically, the angle of multiple synchronous detection modules is adjusted by the adjustment module to facilitate the placement of building construction materials. After the building construction materials are placed, the adjustment module is reverse-driven to reset the multiple synchronous detection modules, and the seepage resistance test is carried out through the multiple synchronous detection modules.

[0064] Example 2, based on Example 1, please refer to... Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 8 In this embodiment of the invention, the adjustment module includes a lifting mounting frame 4 disposed directly above the support mounting base 1. A drive rotating column 5 is rotatably disposed on the lifting mounting frame 4. A spacing adjustment telescopic column 3 is connected between the lifting mounting frame 4 and the support mounting base 1. A directional telescopic column 2 is symmetrically disposed on both sides of the spacing adjustment telescopic column 3. The two ends of the directional telescopic column 2 are respectively connected to the support mounting base 1 and the lifting mounting frame 4.

[0065] By driving the rotation of the rotating column 5, the angle of multiple sets of synchronous detection modules can be adjusted, which facilitates the loading and unloading of building construction materials. At the same time, under the extension and retraction adjustment of the spacing adjustment telescopic column 3, the spacing between the multiple sets of synchronous detection modules and the building construction materials can be changed to ensure the subsequent seepage resistance test.

[0066] With the cooperation of the directional telescopic column 2, the spacing adjustment process becomes more stable.

[0067] Example 3, based on Example 2, please refer to... Figure 1 , Figure 2 , Figures 6-10 In this embodiment of the invention, the multiple sets of synchronous detection modules include a synchronous hydraulic cylinder 7 positioned directly above the loading mounting plate 12, a synchronous piston disc 33 disposed inside the synchronous hydraulic cylinder 7, and the outer side of the synchronous hydraulic cylinder 7 connected to the drive rotating column 5 via a swing mounting plate 6. Several independent detection units are disposed on the lower side of the synchronous hydraulic cylinder 7.

[0068] The upper end of the synchronous hydraulic cylinder 7 is provided with a drive mounting cylinder 8. A limiting rotating sleeve 35 is provided at the middle position of the upper end of the drive mounting cylinder 8. An internal thread transmission cylinder 34 is provided inside the limiting rotating sleeve 35. A lifting threaded column 18 is provided in conjunction with the internal thread transmission cylinder 34. A limiting rotating ring 36 is provided on the outer side of the internal thread transmission cylinder 34 by the limiting rotating sleeve 35. Transmission gear rings 39 are symmetrically provided on the outer sides of both ends of the internal thread transmission cylinder 34. Several adjusting drive components 37 are provided at equal angles on the upper end of the drive mounting cylinder 8. Both ends of the piston ring 39 are equipped with drive gears 38 that mesh with the drive gear ring 39. The upper end of the lifting threaded column 18 is provided with a lifting mounting plate 9. The lifting mounting plate 9 is provided with a plurality of directional guide holes 42 at equal angles. A directional guide post 23 is provided in each of the directional guide holes 42. One end of the directional guide post 23 is connected to the drive mounting cylinder 8. The other end of the directional guide post 23 is provided with a guide limiting piece 24. The lower end of the lifting threaded column 18 is provided with a limiting shaft 40. The upper side of the synchronous piston disc 33 is provided with a limiting bearing sleeve 41 in cooperation with the limiting shaft 40.

[0069] The independent detection unit includes a wide-diameter hydraulic cylinder 10 connected to the lower side of a synchronous hydraulic cylinder 7. A detection piston disc 30 is installed inside the wide-diameter hydraulic cylinder 10. A reduced-diameter detection cylinder 11 is installed at the lower end of each wide-diameter hydraulic cylinder 10. An anti-deviation guide cylinder 31 is installed on the upper side of the detection piston disc 30. An anti-deviation guide post 32 is installed in conjunction with the anti-deviation guide cylinder 31. The upper end of the anti-deviation guide post 32 is fixed to the lower side of the synchronous piston disc 33. An inner-fastening rubber ring 29 is installed at the lower end of the reduced-diameter detection cylinder 11. A compression sealing ring 25 is installed on the outer side of the inner-fastening rubber ring 29. A sponge disc 26 is placed inside the inner-fastening rubber ring 29. A retaining ring 28 is installed on the outer side of the sponge disc 26 in conjunction with the inner-fastening rubber ring 29. A plurality of seepage guide holes 27 are evenly arranged on the sponge disc 26.

[0070] Depending on the type of permeability test, the sponge disc 26 can absorb the same type of experimental permeate or different types of experimental permeate. With the cooperation of the retaining ring 28 and the inner buckling rubber ring 29, the sponge disc 26 with the experimental permeate is placed into the diameter reduction test cylinder 11.

[0071] By driving the rotating column 5, the synchronous hydraulic cylinder 7 is positioned directly in front of the building materials. By adjusting the spacing of the telescopic column 3, the compression sealing ring 25 comes into contact with and is compressed against the building materials to achieve a sealed connection. Then, the adjusting drive component 37 is activated, causing the drive gear 38 to rotate and mesh with the transmission gear ring 39. With the cooperation of the limiting rotating ring 36 and the limiting rotating sleeve 35, the internal thread transmission cylinder 34 rotates accordingly. With the directional sliding cooperation of the directional guide hole 42 and the directional guide column 23, the lifting and lowering adjustment of the lifting thread column 18 is achieved.

[0072] With the cooperation of the limiting rotating shaft 40 and the limiting bearing sleeve 41, the synchronous piston disc 33 is adjusted in sync with the lifting threaded column 18. The hydraulic pressure on one side of the synchronous piston disc 33 is adjusted in sync with the lifting adjustment. When the synchronous piston disc 33 moves downward, it squeezes the hydraulic oil below, causing it to be squeezed from the synchronous hydraulic cylinder 7 into the wide-diameter hydraulic cylinder 10. The pressure on one side of the detection piston disc 30 increases, causing the experimental permeate in the sponge disc 26 to be squeezed out from the surface and the permeation guide hole 27 and cover the building test material inside the squeezing sealing ring 25. The target pressure is reached and the pressure is maintained for a period of time. Then, the reverse drive adjustment drive 37 is used to remove the pressure. With the cooperation of the adjustment module, the building construction material is taken out and the permeation status is recorded. Multiple sets of experimental data can be obtained at once. Since the test is carried out simultaneously, the pressure, temperature, humidity and other environmental conditions are naturally very similar. Whether it is a single test with multiple sets of the same permeation test or a control test, the professionalism of the test is significantly improved.

[0073] When the construction materials on the independent testing unit cannot complete the test and pressure loss occurs, the inner wall of the reduced diameter testing cylinder 11 limits the testing piston disc 30 under the guidance of the anti-deviation guide column 32 and the anti-deviation guide cylinder 31, preventing pressure loss in all independent testing units and significantly reducing the pressure fluctuation range. Normal anti-seepage testing can be restored by simply starting the adjustment drive component 37 for a short pressurization, making the device highly resistant to risks and interference.
