Description

Technical Field

[0001] The present application relates to the technical field of concrete, and particularly to a grouting device for a precast concrete composite slab. Background Art

[0002] A composite floor slab is an assembled integral floor slab formed by laminating a precast slab and a cast-in-place reinforced concrete layer. It is not only one of the components of the floor slab structure but also a permanent formwork for the cast-in-place reinforced concrete composite layer. The composite floor slab has good integrity, and the upper and lower surfaces of the slab are flat, which is convenient for the decoration of the finishing layer. It is suitable for high-rise buildings and large-span buildings with higher requirements for overall stiffness.

[0003] The prior art utility model with the authorized publication number CN210453120U discloses a concrete pouring device for the production of precast composite slabs, including a support beam. A set of symmetrically arranged slide rails are connected to the top of the support beam. A grouting device is arranged between the slide rails. The grouting device includes a main frame and a spraying device. Sliders matching the slide rails are connected to both sides of the main frame. A grouting port, an air injection port, and a water injection port are sequentially arranged at the top of the main frame. The interior of the main frame is a cavity.

[0004] With the above technical solution, by injecting gas into the main frame through an air pump, the pouring speed of concrete can be controlled by controlling the air pressure value of the air pump. Compared with the traditional method that only relies on gravity, the pouring speed of this device is controllable. By adjusting the operating power of the air pump, the stable and continuous pouring process can be realized, and the phenomenon of fast and slow pouring can be prevented. However, with the above technical solution, only the pouring speed of concrete can be controlled through the air pump, and the concrete stored in the device cannot be stirred. Before pouring, the concrete is prone to solidify during transportation, resulting in poor forming effect after pouring. Summary of the Utility Model

[0005] The purpose of the present application is to solve the problem in the prior art that the concrete stored in the device cannot be stirred, and before pouring, the concrete is prone to solidify during transportation, resulting in poor forming effect after pouring, and to propose a grouting device for a precast concrete composite slab.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Refer to Figures 1-5, A grouting device for a precast concrete composite slab of the present application includes two moving plates 1. Two universal wheels 7 are fixedly connected to the bottom surface of each moving plate 1. Two support rods 5 are fixedly connected to one side surface of the two moving plates 1 close to each other. The ends of the two groups of support rods 5 close to each other are jointly fixedly connected to a fixed frame 6. Two reinforcing rings 8 are fixedly connected to the outer surface of each group of universal wheels 7. The top ends of each group of reinforcing rings 8 are fixedly connected to the bottom surface of the moving plate 1. Through the reinforcing ring 8, the universal wheel 7 and the moving plate 1 can be reinforced, enhancing the stability of the device and preventing it from shaking and shifting during use.

[0024] The inner wall of the fixed frame 6 is fixedly connected with a storage bucket 12. A control panel 10 is fixedly connected to the left side surface of one of the moving plates 1. The inner wall of the storage bucket 12 is fixedly connected with a top cover 11. A bearing 21 is fixedly connected to the inner wall of the top cover 11. Two fixing rings 4 are fixedly connected to the outer surface of each group of support rods 5. The ends of the two groups of fixing rings 4 away from each other are fixedly connected to the side surfaces of the two moving plates 1 close to each other. Through the fixing ring 4, the support rod 5 and the moving plate 1 can be fixed, effectively avoiding the problem of unstable position deviation during work.

[0025] The top end of the top cover 11 is fixedly connected with a support frame 14. A driving motor 15 is fixedly connected to the upper surface of the support frame 14. The output end of the driving motor 15 is fixedly connected with a first rotating rod 17. A first bevel gear 18 is fixedly connected to the outer surface of the first rotating rod 17. A reinforcing frame 9 is fixedly connected to the outer surface of the control panel 10. The right side surface of the reinforcing frame 9 is fixedly connected to the left side surface of one of the moving plates 1. Through the reinforcing frame 9, the control panel 10 and the moving plate 1 can be reinforced, playing a strong fixing role and preventing their positions from shifting.

[0026] The outer surface of the first bevel gear 18 meshes with a second bevel gear 19. The inner wall of the second bevel gear 19 is fixedly connected with a second rotating rod 20. The bottom end of the second rotating rod 20 is fixedly connected with a rotating disk 22. The bottom end of the rotating disk 22 is fixedly connected with a spiral stirring rod 16 and two auxiliary stirring rods 23. A protective shell 3 is fixedly connected to the outer surface of the driving motor 15. The bottom surface of the protective shell 3 is fixedly connected to the top end of the top cover 11. Through the protective shell 3, the driving motor 15 can be protected, playing a strong protection role and preventing it from being interfered by the outside during use.

[0027] The outer surface of the storage bucket 12 is fixedly connected and communicated with a feeding pipeline 2, the bottom end of the storage bucket 12 is fixedly connected and communicated with a discharging pipeline 13, the control panel 10 is electrically connected to the driving motor 15 through a wire. A limiting ring 24 is fixedly connected to the outer surface of each auxiliary stirring rod 23, and the top end of each limiting ring 24 is fixedly connected to the bottom end of the rotating disk 22. Through the limiting ring 24, the auxiliary stirring rod 23 and the rotating disk 22 can be fixed, playing a role of fixing and limiting, and preventing the problem that the auxiliary stirring rod 23 shakes and sways during the working process.

[0028] The working principle of the present utility model is as follows: When in use, first, concrete materials are added into the storage bucket 12 through the feeding pipeline 2. Then, by making the output end of the driving motor 15 perform a forward rotational movement, the first rotating rod 17 is driven to rotate, and then the first bevel gear 18 is driven to rotate, causing the second bevel gear 19 to rotate, and further driving the second rotating rod 20 to rotate, so that the rotating disk 22 rotates. Thus, the spiral stirring rod 16 and the auxiliary stirring rod 23 can be driven to perform a rotational movement, thereby being able to stir the concrete inside the storage bucket 12. Then, the device is moved above the laminated board where grouting work needs to be carried out through the universal wheels 7. By making the output end of the driving motor 15 perform a reverse rotational movement, the rotating disk 22 can be made to rotate in the reverse direction, and further the spiral stirring rod 16 can be made to rotate in the reverse direction. Thus, the concrete inside the storage bucket 12 can be conveyed into the discharging pipeline 13 and then fall into the laminated board to complete the grouting work, enhancing the applicability of the device, and effectively avoiding the problem that the concrete stored in the device cannot be stirred, resulting in the concrete solidifying during transportation and poor forming effect after pouring.
