Description

Technical Field

[0001] This utility model relates to the field of auxiliary tools for concrete performance testing, specifically a fixing mechanism for concrete durability testing. Background Technology

[0002] Concrete durability is a core indicator for measuring the long-term safety performance of building structures. However, concrete specimens are prone to shaking and falling off during impermeability durability tests. Therefore, in order to ensure the accuracy of experimental data, a fixing mechanism is often needed to fix the concrete specimens.

[0003] However, existing concrete durability testing fixtures cannot fix concrete of different specifications, resulting in poor adaptability. Furthermore, existing concrete durability testing fixtures are prone to detachment and shaking of concrete specimens during impermeability durability testing, leading to poor stability of the concrete specimens. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a fixing mechanism for concrete durability testing.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This utility model provides a fixing mechanism for concrete durability testing, including a clamping assembly and two jacking assemblies. The clamping assembly is provided with sliding plates on both sides of its top. A first baffle is welded to one side of each of the two sliding plates. The two jacking assemblies are respectively located at the top center of the two first baffles. A pressure plate is provided at one end of the jacking assembly near the first baffle. Ear plates are welded to both ends of the two first baffles on the jacking assembly. A side pressure assembly is provided on each of the two ear plates on both sides of the two first baffles. A second baffle is provided at one end of the side pressure assembly.

[0006] Preferably, the clamping assembly is provided with a support plate, a motor is installed in the middle of one end of the support plate, and a lead screw is movably connected to one end of the motor via a rotating shaft. Screw holes adapted to the lead screw are opened in the middle of one side of both slides.

[0007] Preferably, slide rails are welded to both sides of the support plate near the lead screw, and sliders adapted to the slide rails are welded to both sides of the bottom of the slide plate.

[0008] Preferably, the jacking assembly is provided with a connecting plate, which is welded to the first baffle. A first hydraulic cylinder is provided at one end of the jacking assembly away from the slide plate. A first hydraulic rod is connected to the bottom of the first hydraulic cylinder, and the bottom of the first hydraulic rod is connected to the middle of one side of the pressure plate by bolts.

[0009] Preferably, a second hydraulic cylinder is provided at one end of the side pressure component, and a second hydraulic rod is connected to one end of the second hydraulic cylinder. One end of the second hydraulic rod is connected to the middle of one side of the second baffle by bolts.

[0010] Preferably, the two actuating components are symmetrically arranged, the side pressing components on the two ear plates are symmetrically arranged, and the pressure plate and the second baffle are both rectangular parallelepiped structures.

[0011] The beneficial effects of this utility model are:

[0012] 1. By turning on the motor, the motor drives the two sliding plates on the lead screw to move, adjusting the distance between the two first baffles. This facilitates the fixing of concrete specimens of different specifications by the two first baffles, making the fixing mechanism more adaptable in use. At the same time, the movement of the two sliding plates driven by the lead screw ensures that the two first baffles are more stable during movement, thus making the contact between the two first baffles and the concrete specimens placed on the two sliding plates more stable. This avoids unnecessary damage to the concrete specimens caused by excessive pressure from the two first baffles, helps maintain the integrity of the specimens, and further helps to ensure more accurate data in the subsequent impermeability and durability tests of the concrete specimens.

[0013] 2. By using the first hydraulic cylinder on the jacking assembly to move the pressure plate at one end of the first hydraulic rod, and the second hydraulic cylinder on each side pressure assembly to move the second baffle at one end of the second hydraulic rod, it is beneficial to fix the concrete specimen at multiple points and angles. This makes the pressure plate and the second baffle fit more tightly with the concrete specimen, thereby ensuring that the fixing mechanism fixes the concrete specimen more stably. This meets the positioning requirements of the concrete specimen impermeability durability test. At the same time, the positioning and fixing of the concrete specimen by the cooperation between the various components saves manpower and shortens the fixing time of the concrete specimen, which further helps to improve the working efficiency of the concrete specimen impermeability durability test.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1-5 As shown, a fixing mechanism for concrete durability testing according to the present invention includes a clamping assembly 1 and two jacking assemblies 2. The clamping assembly 1 has sliding plates 104 on both sides of its top. A first baffle 105 is welded to one side of each sliding plate 104. The two jacking assemblies 2 are respectively located at the top center of the two first baffles 105. A pressure plate 204 is provided at one end of the jacking assembly 2 near the first baffle 105. Ear plates 106 are welded to both ends of the two first baffles 105 near the jacking assembly 2. A side pressure assembly 3 is provided on each of the two ear plates 106 on both sides of the two first baffles 105. A second baffle 303 is provided at one end of the side pressure assembly 3.

[0023] The clamping assembly 1 is provided with a support plate 101. A motor 102 is installed in the middle of one end of the support plate 101. One end of the motor 102 is movably connected to a lead screw 103 via a rotating shaft. Each of the two sliding plates 104 has a screw hole in the middle of one side that matches the lead screw 103. By turning on the motor 102, the motor 102 drives the two sliding plates 104 on the lead screw 103 to move, adjusting the distance between the two first baffles 105. This makes it easier for the two first baffles 105 to fix concrete specimens of different specifications, making the fixing mechanism more adaptable in use.

[0024] Slide rails 107 are welded to both sides of the support plate 101 near the lead screw 103, and sliders 108 adapted to the slide rails 107 are welded to both sides of the bottom of the slide plate 104. By cooperating with the lead screw 103 to drive the two slide plates 104 to move, the two first baffles 105 are more stable during movement, so that the two first baffles 105 make more stable contact with the concrete specimen placed on the two slide plates 104, avoiding unnecessary damage to the concrete specimen due to excessive pressure from the two first baffles 105, and helping to maintain the integrity of the specimen.

[0025] A connecting plate 201 is provided on the jacking assembly 2. The connecting plate 201 is welded to the first baffle 105. A first hydraulic cylinder 202 is provided at one end of the jacking assembly 2 away from the sliding plate 104. A first hydraulic rod 203 is connected to the bottom of the first hydraulic cylinder 202. The bottom of the first hydraulic rod 203 is connected to the middle of one side of the pressure plate 204 by bolts. The first hydraulic cylinder 202 on the jacking assembly 2 drives the pressure plate 204 at one end of the first hydraulic rod 203 to move. This helps to make the concrete specimen fit tightly with the sliding plate 104, avoids the concrete from shaking during the impermeability and durability test, and further helps to ensure that the data of the concrete specimen in the later impermeability and durability test are more accurate.

[0026] A second hydraulic cylinder 301 is provided at one end of the side pressure assembly 3. The second hydraulic cylinder 301 is connected by a bolt lug 106. A second hydraulic rod 302 is connected to one end of the second hydraulic cylinder 301. One end of the second hydraulic rod 302 is connected to the middle of one side of the second baffle 303 by a bolt. The second hydraulic cylinder 301 on each side pressure assembly 3 drives the second baffle 303 at one end of the second hydraulic rod 302 to move, which is beneficial to fix the concrete specimen at multiple angles. This makes the pressure plate 204 and the second baffle 303 fit more tightly with the concrete specimen, thereby ensuring that the fixing mechanism fixes the concrete specimen more firmly and thus meets the positioning requirements of the concrete specimen impermeability durability test.

[0027] The two jacking components 2 are symmetrically arranged, and the side pressing components 3 on the two ear plates 106 are symmetrically arranged. The pressure plate 204 and the second baffle 303 are both rectangular structures, which facilitates the positioning and fixing of the concrete specimen by the cooperation between the various components, thereby saving manpower, shortening the time for fixing the concrete specimen, and further improving the working efficiency of the concrete specimen impermeability durability test.

[0028] In use, first, turn on the motor 102. The motor 102 drives the two slide plates 104 on the lead screw 103 to move. Adjust the distance between the two slide plates 104 according to the specifications of the concrete specimen. Place the concrete specimen that needs to be tested for impermeability and durability on the two slide plates 104. The two first baffles 105 fix the concrete specimens of different specifications.

[0029] Then, the first hydraulic cylinder 202 on the jacking assembly 2 drives the pressure plate 204 at one end of the first hydraulic rod 203 to move, and the second hydraulic cylinder 301 on each side pressing assembly 3 drives the second baffle 303 at one end of the second hydraulic rod 302 to move. This is beneficial for fixing the concrete specimen at multiple angles, so that the pressure plate 204 and the second baffle 303 fit more tightly with the concrete specimen, thereby ensuring that the fixing mechanism fixes the concrete specimen more firmly.

[0030] Finally, adjust the position of the concrete specimen, adjust the support plate 101 to the top, and place the concrete specimen in water to conduct a seepage resistance and durability test.
