[0031] The working principle of the concrete flexural and compressive test equipment is described as follows: the movable workbench 3 and the rotating mechanism 4 can adapt to concrete test pieces of various lengths and multiple types of tests, and when in use, the motor 42 drives the bidirectional threaded rod 41 to rotate, and the threads of the bidirectional threaded rod 41 drive the two T-shaped sliding blocks 33 and the workbench 31 to slide to the middle or move outward, so as to adjust the distance. Different concrete test scenarios may require test pieces of different sizes, and the traditional test equipment with fixed intervals cannot meet the requirements of multiple sizes. The design of the adjustable distance workbench can adapt to concrete test pieces of various lengths, and both small laboratory test pieces and large engineering structure simulation test pieces can be placed by adjusting the distance between the workbenches, effectively solving the problem of equipment incompatibility caused by different test piece sizes. The design makes the equipment not only suitable for flexural test, but also suitable for compressive test. For flexural test, the distance between the workbenches can be adjusted according to the length of the test piece and the test standard, such as three-point flexural or four-point flexural, and then the test piece is fixed by the clamp. During compressive test, the distance can also be adjusted to place and fix the test piece, without the need for complex modification or replacement of the equipment, thereby enhancing the versatility of the equipment for different test types.

[0032] The clamping mechanism 5 can fix test bodies of different sizes. When in use, the motor two 535 drives the bidirectional threaded rod two 534 to rotate, and the threads of the bidirectional threaded rod two 534 drive the front left and right T-shaped sliding blocks two 531 to move to the middle or move outward, thereby driving the T-shaped sliding blocks two 531 and the rubber layer 533 to move and clamp and fix the test body 32. During the test process, the test piece needs to be firmly fixed, otherwise the displacement during loading will seriously affect the test result. By fixing the test piece using the clamping mechanism 5 after adjusting the distance, the test piece can be prevented from sliding, rotating and other unstable conditions during flexural or compressive test, so that the test is carried out under stable conditions, thereby improving the reliability of the test data. The clamping and fixing effect of the clamping mechanism 5 ensures the positional accuracy of the test piece during the test process. In flexural test, accurate fixing can ensure the accurate positions of the loading point and the support point, so that the test result can truly reflect the flexural performance of the test piece. In compressive test, the test piece is fixed at the center position and does not shift, which can ensure that the loading force is uniformly applied to the test piece, thereby reducing the test error caused by the displacement of the test piece and improving the accuracy of the test data.

[0033] The above describes the utility model in general, but some modifications or improvements can be made on the basis of the utility model, which is obvious to those skilled in the art. Therefore, without departing from the spirit of the utility model, the modifications or improvements are within the scope of protection of the utility model.
