[0002] Reinforced concrete floors have the characteristics of high strength, good stiffness, good fire resistance and durability, strong plasticity, etc., and are convenient for industrial production in our country and are the most widely used. However, the current reinforced concrete floor structure is relatively simple. Especially, single-layer reinforced concrete floors are prone to cracks when subjected to impact. This not only poses a great hidden danger to the safety of people's residences, but also is prone to the danger of collapse in the later stage.

[0003] A prior patent (publication number: CN214785651U) discloses a structure for preventing concrete cracks, including a concrete floor. Vertical bars and horizontal bars are installed inside the concrete floor. Horizontal installation grooves are opened on both surfaces of the concrete floor. Horizontal water inlet pipes are embedded in the concrete floor through the horizontal installation grooves. A connecting sleeve is installed in the middle of the horizontal water inlet pipes. Vertical installation grooves are opened on both end surfaces of the concrete floor.

[0004] It is pointed out in the above-mentioned comparative document that the beneficial effects achieved by this utility model are: by installing small-diameter vertical bars and horizontal bars inside the concrete floor, the crack resistance of the concrete is improved; by embedding horizontal water inlet pipes, first vertical water pipes and second vertical water pipes inside the concrete floor, and injecting water through the water inlet of the horizontal water inlet pipe, the water flow passes through the horizontal water inlet pipe and flows through the first vertical water pipe and the second vertical water pipe, improving the heat dissipation effect of the concrete, reducing the temperature difference between the inside and outside of the concrete, and thus reducing the possibility of concrete cracking. However, when pouring this device, it needs to be pushed manually, which is time-consuming and laborious, affecting the time for construction workers to prevent cracks in the concrete. The construction time is relatively long and the work efficiency is low. Utility Model Content

[0031] Please refer to Figure 1 , Figure 2 and Figure 3, a concrete crack prevention structure in this embodiment includes a first fixing plate 1 and a second fixing plate 9. At the upper ends of the first fixing plate 1 and the second fixing plate 9, a first motor 3 is fixedly connected. The output ends of the two first motors 3 respectively penetrate through one side of the first fixing plate 1 and the second fixing plate 9 and are fixedly connected with threaded rods 4. The outer walls of the two threaded rods 4 are threadedly connected with sliders 5. A connecting plate 6 is fixedly connected between the two sliders 5. At the upper end of the connecting plate 6, two second motors 7 are fixedly connected. The two second motors 7 respectively penetrate through the connecting plate 6 and are fixedly connected with brush blades 8. Grooves 2 are provided on one side of the first fixing plate 1 and the second fixing plate 9. The threaded rods 4 are placed in the grooves 2. At the lower ends of the first fixing plate 1 and the second fixing plate 9, two fixing blocks 10 are fixedly connected. The traveling wheels 11 are installed by the fixing blocks 10. At the lower ends of the four fixing blocks 10, the traveling wheels 11 are fixedly connected. A connecting rod 19 is fixedly connected between two of the four traveling wheels 11. A belt 22 is sleeved on the output end of the third motor 21 and one end of the connecting rod 19. By connecting the output end of the third motor 21 and the connecting rod 19 through the belt 22, the third motor 21 drives the connecting rod 19 to rotate, thereby driving the traveling wheels 11 to rotate and driving the device to move. A bracket 20 is fixedly connected to one side of the constant temperature box 12. A third motor 21 is fixedly connected to the upper end of the bracket 20. By starting the first motor 3 to drive the threaded rod 4 to rotate, the slider 5 and the connecting plate 6 are driven to adjust the height according to the height of the concrete, so that the brush blade 8 is close to the concrete surface. After fixing, start the water pump 13 to pump water from the constant temperature box 12, enter the nozzle 16 through the connecting pipe 15, and spray the surface of the concrete to prevent the surface of the concrete from cracking. At the same time, the brush blade 8 will cooperate with the nozzle 16 to clean the surface of the concrete, making the water spraying more uniform. The water in the constant temperature box 12 is used to spray the surface of the concrete.

[0032] Please refer to Figure 1 , Figure 2 and Figure 3 , a constant temperature box 12 is fixedly connected to one side of the second fixing plate 9. A water pump 13 is fixedly connected to the upper end of the constant temperature box 12. The output end of the water pump 13 is fixedly connected with a connecting pipe 15. A plurality of nozzles 16 are fixedly connected to one side of the connecting pipe 15. The input end of the water pump 13 is fixedly connected with a water suction pipe 14. The water pump 13 pumps water from the constant temperature box 12 through the water suction pipe 14. The connecting pipe 15 penetrates through the second fixing plate 9. The connecting pipe 15 is used for sprinkling water by passing through the second fixing plate 9. A rotating shaft 17 is rotatably connected between the first fixing plate 1 and the second fixing plate 9. A pressing wheel 18 is connected by the rotating shaft 17. The pressing wheel 18 is fixedly connected to the outer wall of the rotating shaft 17.

[0033] In this embodiment, the output end of the third motor 21 is connected to the connecting rod 19 through a belt 22. Thus, the third motor 21 drives the connecting rod 19 to rotate, which in turn drives the traveling wheel 11 to rotate, driving the device to move, saving time and effort. Start the first motor 3 to drive the threaded rod 4 to rotate, thereby driving the slider 5 and the connecting plate 6 to adjust the height according to the height of the concrete, so that the brush blades 8 are close to the surface of the concrete. After fixing, start the water pump 13 to pump water from the constant temperature box 12, enter the nozzle 16 through the connecting pipe 15, and spray the surface of the concrete to prevent the surface of the concrete from cracking. At the same time, the brush blades 8 will cooperate with the nozzle 16 to clean the surface of the concrete, making the water spraying more uniform. By spraying the surface of the concrete with the water in the constant temperature box 12, it can be used in any season, effectively preventing the surface of the concrete from cracking. The operation is simple, and the device is convenient for the staff to construct, improving the work efficiency.

[0034] It should be noted that the device is convenient for workers to work, and the pressing wheel 18 can also be used when the device is laying cement.

[0035] The working principle of the above embodiment is as follows: When the device is in use, first connect the output end of the third motor 21 to the connecting rod 19 through a belt 22. Thus, the third motor 21 drives the connecting rod 19 to rotate, which in turn drives the traveling wheel 11 to rotate, driving the device to move. The first fixing plate 1 and the second fixing plate 9 are placed above the concrete through the traveling wheels 11. Then start the first motor 3 to drive the threaded rod 4 to rotate, thereby driving the slider 5 and the connecting plate 6 to adjust the height according to the height of the concrete, so that the brush blades 8 are close to the surface of the concrete. After fixing, start the water pump 13 to pump water from the constant temperature box 12, enter the nozzle 16 through the connecting pipe 15, and spray the surface of the concrete to prevent the surface of the concrete from cracking. At the same time, the brush blades 8 will cooperate with the nozzle 16 to clean the surface of the concrete, making the water spraying more uniform. By spraying the surface of the concrete with the water in the constant temperature box 12, it can be used in any season, effectively preventing the surface of the concrete from cracking. The operation is simple and convenient to use. At the same time, a pressing wheel 18 is added to compress and repair the cracks on the surface of the concrete.
