Description

Technical Field

[0001] This utility model relates to the field of concrete impermeability testing technology, and in particular to a concrete impermeability testing device for building engineering. Background Technology

[0002] Concrete is made by mixing cement as a binder, sand and stone as aggregates, and water in a certain proportion. It is widely used in the field of civil engineering. The impermeability of concrete is one of the important indicators of concrete quality, which refers to its ability to resist the penetration of water and other liquid media under pressure.

[0003] A search revealed that the utility model patent with authorization announcement number CN221056285U discloses a device for testing the impermeability of building concrete test blocks. This device can automatically adjust the water pressure according to a preset program, automatically obtain the water seepage of the concrete test block, quantify the water seepage, and prevent high-pressure water from leaking along the side wall of the concrete test block.

[0004] Although the above-mentioned device can complete the test of the impermeability of concrete test blocks, after the test is completed, the concrete test block is located inside the mounting base and is held by the elastic seal, so it is difficult to pull it out upwards. At the same time, the repeated extraction of concrete test blocks further increases the manpower consumption in the testing process.

[0005] Therefore, it is necessary to invent a concrete impermeability testing device for building engineering to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a concrete impermeability testing device for building engineering, which can simultaneously lift multiple specimens after testing, thereby reducing the difficulty of removing multiple specimens, saving manpower, and making it more convenient to use. This solves the problem mentioned in the background art that after testing, the concrete specimen is located inside the mounting base and is clamped by the elastic seal, making it difficult to pull it out. At the same time, the repeated extraction of the concrete specimen further increases the manpower consumption in the testing process.

[0007] According to one aspect of this disclosure, the following technical solution is provided: a concrete impermeability testing device for building engineering, comprising:

[0008] A concrete test block receiving mechanism, wherein the concrete test block receiving mechanism is used to receive concrete test blocks;

[0009] A downward pressure limiting mechanism, wherein the downward pressure limiting mechanism is used to limit the position of the concrete test block; and

[0010] The ejection mechanism includes a hydraulic cylinder B, a lifting plate, an ejection rod, and a guide sleeve;

[0011] Two hydraulic cylinders B are provided and are fixedly installed on the top two sides of the workbench respectively. The lifting plate is located at the bottom of the workbench and is fixedly installed at the bottom end of the output shaft of the two hydraulic cylinders B. Multiple ejector rods and guide sleeves are provided. Multiple ejector rods are evenly fixedly installed on the top of the lifting plate. Multiple guide sleeves are slidably sleeved on the outside of multiple ejector rods and are evenly fixedly nested at the bottom of the workbench. Any one of the guide sleeves is connected to the adjacent elastic seal. A water inlet pipe is fixedly installed through the front of any one of the guide sleeves.

[0012] According to at least one embodiment of the concrete impermeability testing device for building engineering according to the present disclosure, a sealing channel is provided at the bottom of any one of the guide sleeves, the push rod is slidably disposed inside the sealing channel, and a sealing ring is fixedly nested inside the sealing channel.

[0013] According to at least one embodiment of the concrete impermeability testing device for building engineering according to the present disclosure, the concrete test block receiving mechanism includes a workbench, and a base is fixedly disposed at the bottom of the workbench.

[0014] According to at least one embodiment of the concrete impermeability testing device for building engineering, a plurality of receiving cylinders are uniformly fixedly arranged on the top of the workbench, and an elastic sealing element is bonded to the inner side of any one of the receiving cylinders.

[0015] According to at least one embodiment of the concrete impermeability testing device for building engineering, the downward pressure limiting mechanism includes a fixed frame fixedly installed on the top of the workbench, guide grooves are provided on both sides of the fixed frame, and hydraulic cylinders A are fixedly installed on both sides of the top of the fixed frame. The bottom ends of the two hydraulic cylinders A are fixedly installed with a descending plate that slides vertically inside the guide groove.

[0016] According to at least one embodiment of the concrete impermeability testing device for building engineering, a plurality of pressure cylinders are uniformly fixedly arranged at the bottom of the descending plate, and the plurality of pressure cylinders are respectively located directly above a plurality of receiving cylinders, and a limit rod is fixedly arranged in the middle of the inner side of any one of the pressure cylinders.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] This invention features an ejector mechanism that allows for continuous water flow into the guide sleeve via the inlet pipe during seepage resistance testing. The water flow impacts the bottom of the specimen through the top opening of the guide sleeve, continuously striking the specimen. During this process, a sealing ring seals the ejector rods and the guide sleeve to prevent water leakage. After testing, two hydraulic cylinders B synchronously move the lifting plate upwards. As the lifting plate moves, multiple ejector rods move upwards simultaneously, pushing them from the bottom of the specimens. This causes the specimens to continuously move upwards from the inside of the elastic seal until they reach the top opening of the receiving cylinder. At this point, multiple specimens can be manually removed. Compared to existing technologies, this invention allows for simultaneous lifting of multiple specimens after testing, reducing the difficulty of removing them, saving manpower, and making it more convenient to use.

[0027] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0029] Figure 2 This is a schematic diagram of the concrete block receiving mechanism 1 and the downward pressure limiting mechanism 2 of a concrete impermeability testing device for building engineering according to one embodiment of the present disclosure.

[0030] Figure 3 This is a schematic diagram of the ejector mechanism 3 of a concrete impermeability testing device for building engineering according to one embodiment of the present disclosure.

[0031] like Figures 1-3 As shown, the concrete impermeability testing device for building engineering disclosed herein may include components such as a concrete test block receiving mechanism 1, a downward pressure limiting mechanism 2, and an ejection mechanism 3.

[0032] like Figure 2 As shown in the present disclosure, the concrete test block receiving mechanism 1 includes a workbench 11, a base 12 is fixedly installed at the bottom of the workbench 11, and a plurality of receiving cylinders 13 are evenly fixedly installed on the top of the workbench 11. An elastic sealing element 14 is bonded to the inner side of any one of the receiving cylinders 13.

[0033] This allows the specimen to be placed inside the elastic seal 14 through the top opening of the receiving cylinder 13, at which point the bottom of the specimen is in contact with the top opening of the guide sleeve 34.

[0034] like Figure 2As shown, in a preferred embodiment, the pressure limiting mechanism 2 includes a fixed frame 21 fixedly mounted on the top of the workbench 11. Guide grooves 22 are provided on both sides of the fixed frame 21. Hydraulic cylinders A23 are fixedly mounted on both sides of the top of the fixed frame 21. A descending plate 24 is fixedly mounted at the bottom of the two hydraulic cylinders A23 and is slidably mounted in the inner side of the guide groove 22 in the vertical direction. A plurality of pressure cylinders 25 are evenly fixedly mounted at the bottom of the descending plate 24. The plurality of pressure cylinders 25 are located directly above the plurality of receiving cylinders 13. A limit rod 26 is fixedly mounted in the middle of the inner side of any one of the pressure cylinders 25.

[0035] Therefore, after the specimen is placed, the two hydraulic cylinders A23 synchronously drive the lowering plate 24 to move down. When the lowering plate 24 moves down, it drives multiple pressing cylinders 25 to move down synchronously, thereby pressing the pressing cylinders 25 against the top of the elastic seal 14. At this time, the elastic seal 14 deforms due to pressure, thus tightly covering the specimen to prevent water from flowing out between the elastic seal 14 and the specimen during subsequent testing. At the same time, the limiting rod 26 presses against the top of the specimen, thereby preventing the specimen from moving due to water flow during testing and causing excessive friction with the elastic seal 14. After the subsequent testing is completed, the pressing limiting mechanism 2 is reset. At this time, the amount of water seepage at the top of the specimen can be observed to determine whether the specimen is qualified.

[0036] like Figure 3 As shown in this disclosure, the ejection mechanism 3 includes a hydraulic cylinder B31, a lifting plate 32, an ejection rod 33, and a guide sleeve 34. Two hydraulic cylinders B31 are provided and fixedly mounted on both sides of the top of the workbench 11. The lifting plate 32 is located at the bottom of the workbench 11 and fixedly mounted at the bottom end of the output shafts of the two hydraulic cylinders B31. Multiple ejection rods 33 and guide sleeves 34 are provided. Multiple ejection rods 33 are evenly fixedly mounted on the top of the lifting plate 32. Multiple guide sleeves 34 are slidably sleeved on the outside of the multiple ejection rods 33 and evenly fixedly nested at the bottom of the workbench 11. A sealing channel is provided at the bottom of each guide sleeve 34. The ejection rod 33 is slidably mounted inside the sealing channel. A sealing ring is fixedly nested inside the sealing channel. Each guide sleeve 34 is connected to an adjacent elastic seal 14. A water inlet pipe 35 is fixedly penetrated through the front of each guide sleeve 34.

[0037] Therefore, during the seepage resistance test, the inlet pipe 35 continuously inputs water into the guide sleeve 34. The water flows through the top opening of the guide sleeve 34 and acts on the bottom of the specimen, thus continuously impacting the specimen. During this process, the sealing ring seals the ejector rod 33 and the guide sleeve 34 to prevent water leakage. After the test is completed, the two hydraulic cylinders B31 synchronously drive the lifting plate 32 to move upward. When the lifting plate 32 moves upward, it drives multiple ejector rods 33 to move upward synchronously, which are then pushed by the bottom of multiple specimens, causing them to move continuously upward from the inside of the elastic seal 14 until they reach the top opening of the receiving cylinder 13. At this point, multiple specimens can be manually removed. Compared with the existing technology, multiple specimens can be lifted simultaneously after the test, thus reducing the difficulty of removing multiple specimens, saving manpower, and making it more convenient to use in practice.

[0038] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0039] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
