[0007] Furthermore, an inner connecting thread is provided on the inner side of the connecting block, and an outer connecting thread matching the inner connecting thread is provided on the outer top of the pressing block, so that different pressing blocks can be easily replaced.

[0008] Furthermore, the top of the lifting plate is connected with a plurality of limit support rods penetrating the supporting top frame, so as to facilitate the stable lifting operation of the lifting plate.

[0009] Furthermore, a plurality of limiting sleeves are connected to the bottom of the limiting groove, and a plurality of limiting sleeve rods fixedly connected to the bottom of the sliding frame are sleeved in the limiting sleeve, so as to facilitate the stable lifting and lowering operation of the sliding frame.

[0010] Furthermore, a limiting sliding block is connected to the outer side of the bottom of the sliding frame, and a limiting sliding groove cooperating with the limiting sliding block is provided on the inner side of the limiting groove, so as to facilitate the limiting operation of the sliding frame.

[0011] The advantages of the building material strength detection device of the utility model compared with the prior art are: the utility model can prevent hard downward pressure through the sliding frame and the weighing device with a certain downward pressure space, thereby reducing damage to the equipment.

[0017] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0018] Combined with Figure 1-4A building material strength testing device comprises a support base 1, the top of the support base 1 is connected to a support frame 2, the top of the support frame 2 is connected to a hydraulic device 3, the hydraulic device 3 needs to be connected to an external infusion pipeline, etc. This is a common prior art, so it is not described in detail. The bottom power end of the hydraulic device 3 extends to the bottom of the support frame 2 and is connected to a lifting plate 4. The top of the lifting plate 4 is connected to a plurality of limit support rods 9 that penetrate the support frame 2. The bottom of the lifting plate 4 is connected to a connecting block 5, and the bottom of the connecting block 5 is connected to a detachable lower The pressing block 6 is provided with a connecting internal thread 7 on the inner side of the connecting block 5, and a connecting external thread 8 matching the connecting internal thread 7 is provided on the outer top of the pressing block 6. Different pressing blocks 6 can be replaced by connecting the internal thread 7 and the connecting external thread 8, so that pressing blocks of different sizes can be replaced according to the strength test of different building materials. A limiting groove 10 is provided in the supporting base 1, and a sliding frame 11 is provided in the limiting sliding connection in the limiting groove 10. A weighing device 12 is connected to the top of the sliding frame 11, and the weighing device 12 can be used to preliminarily test the downward pressure.

[0019] During the specific implementation: the building materials whose material strength needs to be tested are placed on the weighing device 12, and then the hydraulic device 3 drives the lifting plate 4 and the bottom pressing block 6 to perform a downward pressing operation, so that the downward pressure is weighed by the weighing device 12, so that the material strength can be tested.

[0020] A plurality of main sleeves 13 are connected in the limit groove 10, a main sleeve rod 14 is connected in a limit sliding manner in the main sleeve 13, a strong spring 15 is connected in the main sleeve 13 below the main sleeve rod 14, a plurality of limit sleeves 16 are connected at the bottom of the limit groove 10, a plurality of limit sleeve rods 17 fixedly connected to the bottom of the sliding frame 11 are sleeved in the limit sleeve 16, a limit sliding block 22 is connected to the outer side of the bottom of the sliding frame 11, and a limit sliding groove 23 cooperating with the limit sliding block 22 is provided on the inner side of the limit groove 10.

[0021] During specific implementation: when detecting downward pressure, the main sleeve 13, the main sleeve rod 13 and the strong spring 15 can be used to ensure that the sliding frame 11 and the weighing device 12 have a certain downward movement space, thereby reducing the damage caused by hard pressure on the equipment. Through multiple limiting structures, the stable downward pressure of the sliding frame 11 and the weighing device 12 can be guaranteed, thereby ensuring the accuracy of the detection.

[0022] A plurality of piston cylinders 18 are connected to the top of the support frame 2, a piston 19 is connected to the inner side of the piston cylinder 18, a piston rod 20 connected to the lifting plate 4 is connected to the bottom of the piston 19, and a pressure sensor 21 is connected to the top of the piston cylinder 18.

[0023] During specific implementation: because the sliding frame 11 and the weighing device 12 will have a certain downward pressure, the top lifting plate 4 also has a certain downward pressure space, so by detecting the internal pressure of the piston structure, the material pressure strength can be assisted by electrical signals. This equipment can generally only detect building materials that are smaller than multiple strong springs 15, and can accurately detect building materials such as cement concrete, but cannot detect metal materials, etc.

In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
