Description

Technical Field

[0001] The utility model relates to the technical field of concrete impact resistance test, in particular to a concrete impact resistance fatigue test device in a simulated marine environment. Background Art

[0002] In modern marine construction, concrete is the most commonly used building material, and impact resistance is a key item in concrete performance testing. However, it is not easy to test the impact resistance of concrete in a marine environment. The commonly used concrete impact test method is the drop hammer impact test method, and the test environment is basically a normal laboratory test environment, so it is impossible to verify the impact resistance of concrete in a marine environment. There is high chloride ion seawater in the marine environment. The impact fatigue effect of concrete in the marine environment is different from that in a dry laboratory environment. As the concrete continues to crack under the impact fatigue effect, the seawater containing chloride ions will penetrate into the concrete, affecting the impact resistance of the concrete. Utility Model Content

[0003] The utility model aims to provide a concrete impact fatigue test device in a simulated marine environment to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a concrete impact fatigue test device under a simulated marine environment, comprising a base and a test box, wherein a test box is arranged at the top of the base, and the concrete impact fatigue test device under a simulated marine environment also includes: a test mechanism, arranged at the internal top of the test box; an auxiliary mechanism, arranged at the top of the test box.

[0005] When the insertion rod is pulled out from the inside of the groove tube, the groove tube loses its clamping connection, and then the user pulls the pull rod downward to drive the cross plate to move downward at the same time and fit on the top of the test box, and then when the cross plate fits on the top of the test box, both sides of the cross plate are inserted into the inside of the groove block.

[0006] Preferably, a through hole is provided at the center of the support plate.

[0007] Preferably, a circular through hole is provided at the center of the transverse plate.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model is set up, and when the concrete impact fatigue test device under the simulated marine environment is put into use, the problem that the traditional impact test device cannot simulate the impact effect under the marine environment can be solved. At the same time, the device is convenient for testing and can be applied to different types of concrete specimens. By conducting concrete impact tests with different mix ratios, the best mix ratio can be obtained, thereby promoting the quality of the project. Through the use of the test mechanism, a concrete impact test simulating the real marine conditions is achieved. Through the use of the auxiliary mechanism, the work of protecting and blocking the seawater splashed during the test is achieved to prevent the seawater from splashing onto the test personnel and the machine. Through the coordinated use of the above-mentioned structure, the current inability to verify the impact resistance of concrete in the marine environment is solved. BRIEF DESCRIPTION OF THE DRAWINGS

The vertical rods 304 are fixedly arranged at the four corners of the inner wall of the test box 2, and the vertical rods 304 are used to support the support plate 305. The heating device 302 can heat the seawater inside the test box 2, and the temperature of the seawater can be controlled by the temperature control device 303: the support plate 305 5 is fixedly arranged at the top of the vertical rod 304, the motor 306 is fixedly arranged at the top of the support plate 305, the take-up wheel 307 is fixedly arranged at the outer wall of the output shaft of the motor 306, the pull rope 308 is wound and fixedly arranged at the bottom of the outer wall of the take-up wheel 307, and the ball 309 is fixedly arranged at the other end of the pull rope 308, wherein when the motor 306 rotates, the pull rope 308 can be wound by the take-up wheel 307 and the ball 309 can be pulled upward, a rubber strip is processed at the top of the test box 2, and a through hole is opened at the center of the support plate 305.

[0018] More specifically, the auxiliary mechanism 4 includes: a horizontal plate 401, a slot block 402, a pull rod 403, a slot tube 404 and an insertion rod 405;

[0019] The horizontal plate 401 is fitted on the top of the test box 2. The material of the horizontal plate 401 is transparent acrylic material. The horizontal plate 401 is used to protect the splash of water when the ball 309 falls. The groove block 402 is fixedly set on the outer walls of both sides of the test box 2, and the inside of the groove block 402 is plugged with the two sides of the horizontal plate 401. The pull rod 403 is fixedly set on both sides of the top of the horizontal plate 401. The groove tube 404 is sleeved on the outer wall of the vertical rod 304, and the outer side of the groove tube 404 is fixedly connected to the pull rod 403. The insertion rod 405 is inserted into the inside of the groove tube 404, wherein the pull rod 403 is pulled upward to drive the groove tube 404 to move upward at the same time on the outer wall of the vertical rod 304, and then the insertion rod 405 is inserted into the groove tube 404 and the vertical rod 304 for fixation. A circular through hole is opened in the center of the horizontal plate 401.

[0020] Working principle: When the concrete impact fatigue test device under simulated marine environment is used, the user first pulls the pull rod 403 upwards, which drives the horizontal plate 401 to move upwards at the same time, and then moves upwards on the outer wall of the vertical rod 304 through the groove tube 404. The bottom ends of both sides of the horizontal plate 401 are pulled out from the inside of the groove block 402. Then, when the user moves the horizontal plate 401 to the top of the vertical rod 304, the user first inserts the insertion rod 405 through the groove tube 404 into the inside of the vertical rod 304 to fix it, and then the user puts the poured concrete into the top of the test bench 301 The user then pours seawater into the test box 2. When the seawater submerges the concrete, the user heats the seawater through the heating device 302, and then controls the temperature of the seawater at a suitable temperature through the temperature control device 303. When the user pulls the insertion rod 405 out of the groove tube 404, the groove tube 404 loses its clamping connection. Then the user pulls the pull rod 403 downward and drives the cross plate 401 to move downward at the same time and fit on the top of the test box 2. Then, when the cross plate 401 fits on the top of the test box 2, the two sides of the cross plate 401 are inserted into the inside of the groove block 402. Then the user will control the motor 306 to start working through the external control unit. When the output shaft of the motor 306 rotates in the opposite direction, the ball 309 loses the upward pulling force, and the ball 309 falls quickly into the inside of the test box 2 and then hits the poured concrete. When the ball 309 falls and contacts the seawater, the splashing water is protected by the cross plate 401 to prevent the seawater from splashing outward. Then the user controls the motor 306 to start working through the external control unit to drive the take-up wheel 307 to start rotating through the output shaft, and then pulls the ball 309 upward through the pull rope 308 to reset it. Then the user pulls the pull rod 403 upwards, which drives the horizontal plate 401 to move upwards at the same time, and then moves upwards along the outer wall of the vertical rod 304 through the groove tube 404. The bottom ends of both sides of the horizontal plate 401 are pulled out from the inside of the groove block 402. Then, when the user moves the horizontal plate 401 to the top of the vertical rod 304, the user first inserts the insertion rod 405 through the groove tube 404 into the inside of the vertical rod 304 to fix it. Then the user takes out the top of the concrete test bench 301 after the impact. The user can conduct tests and comparisons through different types of poured concrete to select the best concrete.
