[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 the cementitious material, sand and stone as aggregates, and water that may contain admixtures and additives, which are mixed in a certain proportion and obtained by stirring. Concrete slabs are slabs made of concrete. In construction projects, when concrete slabs are needed to construct buildings, they often need to be tested for hardness after they are produced to determine whether they meet the construction requirements.

[0003] In the prior art, when performing hardness testing on building concrete slabs, most of the time, only one area of ​​the concrete slab can be tested. The test results are not representative, and it is difficult to judge the overall hardness of the concrete slab. At the same time, the tiny deformation on the surface of the concrete slab during the hardness testing process is difficult to be observed by the naked eye, which will affect the concrete hardness test results.

[0004] Therefore, a building concrete slab hardness detection device is needed to solve the problems in the prior art that the hardness detection of the fixed area of ​​the concrete slab lacks representativeness and it is difficult to intuitively observe the hardness of the concrete.

[0008] It should be noted in the scheme that the observation mechanism includes an opening, which is arranged in the middle of the bottom wall of the U-shaped plate. A fixed plate is fixed on the inner side of the opening. There are multiple groups of evenly distributed sliding grooves slidably connected inside the fixed plate, and positioning blocks are slidably connected inside the sliding grooves.

[0009] It is further worth mentioning that a limiting rod passes through and is fixed on the inner side of the limiting hole, and the limiting rod is fixed on the lower side of the screw rod between the connecting plates.

[0010] It should be further explained that placement grooves are provided on both the left and right inner sides of the U-shaped plate, and a concrete plate body is provided on the upper side between the placement grooves.

[0011] As a preferred implementation, support rods are fixed at the four corners of the bottom wall of the U-shaped plate, and the lower pressing block is located on the top of the concrete plate body.

[0012] As a preferred implementation, the tops of the positioning blocks are clearance-matched with the bottom wall of the concrete slab body, and the fixing plates are located at the lower middle part of the placement groove.

[0013] Compared with the prior art, the building concrete slab hardness detection device provided by the utility model has at least the following beneficial effects:

[0014] (1) By starting the electric slide, the electric slide drives the slider to move forward and backward during operation, thereby moving the connecting plate forward and backward. At the same time, the drive motor is started, and the output shaft of the drive motor rotates to move the threaded block left and right, so that the cylinder can move forward and backward and left and right on the upper side of the concrete slab body, thereby increasing the hardness detection range of the concrete slab and making the detection result more convincing.

[0020] The utility model is further described below in conjunction with embodiments.

[0021] See also Figure 1-3 The utility model provides a building concrete slab hardness detection device, comprising a U-shaped plate 1, an automatic detection mechanism 2 is arranged on the top of the U-shaped plate 1, and an observation mechanism 3 is arranged on the lower side of the U-shaped plate 1;

[0022] The automatic detection mechanism 2 includes an electric slide 4. When the electric slide 4 is working, the slider 5 will move forward and backward. The forward and backward movement of the slider 5 will drive the connecting plate 6 to move forward and backward. The electric slide 4 is respectively arranged on the left and right walls of the outer side of the U-shaped plate 1. A slider 5 is arranged at the output end of the electric slide 4. A connecting plate 6 is fixed on the top of the slider 5. A screw 8 is rotatably connected to the upper side between the two groups of connecting plates 6. A driving motor 7 is fixed on the upper side of the left wall of the left connecting plate 6. The output shaft of the driving motor 7 is fixed to the screw 8. During the operation of the driving motor 7, the screw 8 will be driven to rotate. The rotation of the screw 8 will move the thread block 9 left and right. With the cooperation of the driving motor 7 and the electric slide 4, the lower pressure block 13 can be moved forward and backward, left and right. The outer periphery of the screw 8 is threadedly connected to the thread block 9. A limiting hole 10 is arranged on the lower side of the inner part of the thread block 9. A cylinder 12 is fixed to the middle of the bottom wall of the thread block 9, and a lower pressure block 13 is fixed to the output end of the cylinder 12.

[0023] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the observation mechanism 3 includes an opening 16, the opening 16 is arranged in the middle of the bottom wall of the U-shaped plate 1, a fixed plate 17 is fixed on the inner side of the opening 16, and a plurality of groups of evenly distributed slide grooves 18 are slidably connected inside the fixed plate 17, and a positioning block 19 is slidably connected inside the slide groove 18. The positioning block 19 slides up and down inside the slide groove 18 so that people can intuitively see the deformation degree of the concrete slab.

[0024] Further as Figure 3 As shown, it is worth explaining in detail that a limiting rod 11 passes through and is fixed on the inner side of the limiting hole 10, and the limiting rod 11 is fixed on the lower side of the screw 8 between the connecting plates 6. The limiting hole 10 cooperates with the limiting rod 11 to prevent the threaded block 9 from rotating during the rotation of the screw 8.

[0025] This solution has the following working process: when it is necessary to perform a hardness test on the concrete slab, first start the electric slide 4. During the operation of the electric slide 4, the slider 5 is driven to move forward and backward, thereby moving the connecting plate 6 forward and backward. At the same time, the drive motor 7 is started, and the output shaft of the drive motor 7 rotates to move the threaded block 9 left and right, so that the cylinder 12 can move forward and backward and left and right on the upper side of the concrete slab body 14, thereby increasing the hardness detection range of the concrete slab. A fixed plate 17, a slide groove 18 and a positioning block 19 are arranged on the lower side of the concrete slab body 14. When the hardness of the concrete slab body 14 is tested, the positioning block 19 slides downward inside the slide groove 18, thereby making the deformation of the concrete slab generated when it is compressed more intuitively displayed.

[0026] According to the above working process, it can be known that with the cooperation of the electric slide 4, the slider 5, the connecting plate 6, the driving motor 7, the screw 8, the threaded block 9, the limit hole 10 and the limit rod 11, the hardness of each position of the concrete slab main body 14 can be tested, thereby improving the test range of the detection device.

The support rods 20 are used to support and fix the U-shaped plate 1 and its upper side components, and at the same time provide space for the positioning block 19 to move up and down.

During the operation of the electric slide 4, the slider 5 is driven to move forward and backward, thereby moving the connecting plate 6 forward and backward. At the same time, the drive motor 7 is started, and the output shaft of the drive motor 7 rotates to move the threaded block 9 left and right, so that the cylinder 12 can move forward and backward and left and right on the upper side of the concrete slab body 14, thereby increasing the hardness detection range of the concrete slab.
