[0002] Concrete, abbreviated as concrete, is a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates, and water in a certain proportion. The cement concrete is also called ordinary concrete. It is widely used in civil engineering. With the rapid development of the construction industry and the highway and bridge industry and the continuous improvement of the design level, the requirements for concrete during construction are very high. Therefore, it is necessary to test its strength during concrete construction.

In order to ensure the overall stability during use, the bottom end of the testing platform 1 is symmetrically welded with support legs 9 of the support assembly, and the bottom end of the support leg 9 is welded with a fixed foot 21, and the bottom end of the fixed foot 21 is provided with an anti-slip texture to improve the friction with the ground.

[0023] See also Figure 1-Figure 5In order to facilitate the rapid placement and positioning of the concrete block 6 to be tested, facilitate subsequent testing operations, avoid movement during the testing process, improve the accuracy of the test, and avoid flying after fragmentation, the testing table 1 is provided with equidistant empty slots 13 (the number can be eight groups or four groups, which can facilitate the subsequent clamping of the concrete block 6 to be tested). A rotating cavity 18 of a rotating mechanism is provided in the two side walls of the empty slot 13, and a rotating rod 17 is rotatably connected to the interior thereof through a volute spring 19, and a clamping block 12 of a clamping assembly is welded to the middle of the rotating rod 17, and an anti-slip pad 14 is bonded to the clamping block 12 for convenient clamping of the side of the concrete block 6 to be tested, and a support plate 15 is horizontally welded at the bottom end of the clamping block 12 for convenient lifting of the bottom of the concrete block 6 to be tested, and two groups of positioning columns 16 are symmetrically and vertically welded in the empty slot 13, which can facilitate the lifting and support of the bottom of the support plate 15 after the concrete block 6 to be tested is placed and clamped, thereby ensuring the positioning effect.

[0024] See also Figure 1-Figure 5 In order to facilitate the detection of the concrete block 6 to be detected and to provide protection during the detection process to avoid the possibility of stone fragments collapsing during fragmentation and ensure safety, four sets of electric push rods 2 with lifting assemblies are equidistantly installed vertically on the detection platform 1, and a lifting plate 3 is installed at the output end (i.e., the top end) of the electric push rod 2. A transparent protective cover 5 is bonded to the bottom end of the lifting plate 3 (the material of which can be made of transparent plastic, etc., which ensures safety while not affecting the viewing of the detection process, and can also be made of other materials, such as bulletproof glass, etc.), and a rubber pad 8 is bonded to the bottom end of the transparent protective cover 5, which can better seal when in contact with the detection platform 1 to ensure the protection effect, and a detection The hydraulic telescopic rod 4 of the component, whose output end passes through the lifting plate 3 and extends to the bottom where a pressure plate 20 is provided, can facilitate the compression test of the concrete block 6 to be tested.

[0025] Working principle: When the utility model is in use, the concrete block 6 to be tested is placed on the test platform 1, and the bottom end is in contact with the support plate 15. Under the action of the gravity of the concrete block 6 to be tested, the support plate 15 generates downward pressure, and then the clamping block 12 and the rotating rod 17 are rotated in the rotating chamber 18. The volute spring 19 stores potential energy, and then cooperates with the anti-slip pad 14 to clamp the side of the concrete block 6 to be tested. At the same time, the bottom end of the support plate 15 is in contact with the positioning column 16 to ensure stability. Then, the electric push rod 2 is retracted to move the lifting plate 3 downward. At this time, the rubber pad 8 under the transparent protective cover 5 is in contact with the test platform 1, and the whole cover can be At this time, the hydraulic telescopic rod 4 is extended, and the pressure plate 20 is moved downward to contact and squeeze the concrete block 6 to be tested, so that it can be tested. The transparent protective cover 5 does not affect the observation during the test and can also improve safety. After the test is completed, the hydraulic telescopic rod 4 can be retracted and reset, and the electric push rod 2 is extended, and the lifting plate 3 is moved upward to open it, and the concrete block 6 to be tested can be removed. The rotating rod 17 is rotated and reset under the potential energy of the volute spring 19, which can be convenient for the next placement test. Then, the collection box 7 works in conjunction with the collection tube 10 and the collection cover 11 to collect the fine debris on the test table 1.
