[0002] Composite precast slabs are a component of prefabricated floor slabs in building construction. During the fabrication process, the thickness of the composite precast slabs needs to be controlled according to requirements. Composite precast slabs are typically made of poured concrete, with a steel truss fixed to the top.

[0003] During the processing of composite precast slabs, molds are usually set up according to the required thickness of the composite precast slabs, and concrete is poured into the molds to control the thickness of the composite precast slabs. However, when composite precast slabs of different thicknesses are required, different molds need to be made. Using the same mold is not convenient for positioning and controlling the thickness of the composite precast slabs, which reduces the practicality of composite precast slab processing.

[0004] Therefore, this utility model provides a thickness positioning device for composite precast slabs. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a composite precast slab thickness positioning device to solve the problems mentioned in the background. This invention uses an adjusting screw and handwheel to adjust the lifting and lowering of the adjusting plate, which facilitates the adjustment of the distance between the bottom end face of the adjusting plate and the bottom plate, thereby positioning the upper end face of the concrete and facilitating the positioning of the thickness of the composite precast slab. At the same time, by adjusting the movement of the adjusting plate, it is convenient to smooth the top of the composite precast slab.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a composite precast slab thickness positioning device, comprising a base plate, with side plates and baffles respectively bolted to the left and right sides and front and rear sides of the base plate. A positioning mechanism is movably arranged between the side plates via a slider. The positioning mechanism includes a fixed frame and an adjusting plate. The adjusting plate is movably installed inside the bottom end of the fixed frame via an adjusting screw. V-shaped grooves are symmetrically formed at the bottom of both ends of the adjusting plate. A limiting mechanism is provided on the inner side of the top end of the V-shaped groove. The limiting mechanism includes a limiting plate, a first square rod, and a second square rod. A groove is formed at the bottom end of the limiting plate.

[0007] Furthermore, the top sidewalls of the two side plates are provided with grooves, and the slider is slidably installed inside the grooves.

[0008] Furthermore, the baffles on the front and rear sides are arranged on the outside of the slide groove and the slider, and the slider is symmetrically fixed on the outer walls of both ends of the fixed frame.

[0009] Furthermore, the fixing frame is disposed between the left and right side plates, and the adjusting screws are symmetrically screwed into the interior of both ends of the fixing frame.

[0010] Furthermore, the adjusting screw is symmetrically rotated and mounted on the top of both ends of the adjusting plate, and a handwheel is fixedly installed on the top of the adjusting screw corresponding to the top of the fixed frame.

[0011] Furthermore, the bottom two sides of the adjustment plate are in contact with the side walls of the left and right side plates, and the adjustment plate is positioned above the base plate.

[0012] Furthermore, the limiting mechanism also includes an inner groove, which is opened above the V-shaped groove and corresponds to the interior of the adjusting plate. The top end of the first square rod is slidably installed inside the inner groove.

[0013] Furthermore, the top end of the second square rod is slidably mounted inside the bottom end of the first square rod. Both the first and second square rods are "T" shaped. The bottom end of the second square rod is fixedly located at the center of the top of the limiting plate, which is located inside the V-groove.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a composite precast slab thickness positioning device. By adjusting the lifting and lowering of the adjusting plate using an adjusting screw and handwheel, the distance between the bottom end face of the adjusting plate and the base plate can be easily adjusted, thereby positioning the upper end face of the concrete. This facilitates the positioning and control of the thickness of the composite precast slab, allowing for the production of composite precast slabs of different thicknesses as needed. The V-groove and limiting plate, among other limiting mechanisms, facilitate the positioning of the steel truss, preventing it from shifting during concrete pouring or vibration, thus improving the stability of the steel truss. The sliding groove and slider can limit the movement of the fixed frame, facilitating the movement of the adjusting plate on top of the concrete and smoothing the top of the composite precast slab, thus enhancing the practicality of the device.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a composite precast slab thickness positioning device, including a base plate 1. Side plates 2 and baffles 3 are respectively installed on the left and right sides and the front and rear sides of the base plate 1 by bolts 7. A positioning mechanism 4 is movably arranged between the side plates 2 by a slider 5. The positioning mechanism 4 includes a fixed frame 8 and an adjusting plate 10. The adjusting plate 10 is movably installed inside the bottom end of the fixed frame 8 by an adjusting screw 9. V-shaped grooves 12 are symmetrically opened at the bottom of both ends of the adjusting plate 10. A limiting mechanism 11 is provided on the inner side of the top end of the V-shaped groove 12. The limiting mechanism 11 includes a limiting plate 16, a first square rod 14 and a second square rod 15. A groove is opened at the bottom end of the limiting plate 16. By adjusting the lifting and lowering of the adjusting plate 10 by the adjusting screw 9, the distance between the bottom end of the adjusting plate 10 and the base plate 1 can be controlled, which facilitates the control of the height of the upper end surface of the concrete, thereby controlling the thickness of the composite precast slab. This facilitates the production of composite precast slabs of different thicknesses and improves the practicality of the device.

[0022] In this embodiment, a groove 6 is provided inside the top side wall of the side plates 2 on both sides. The slider 5 is slidably installed inside the groove 6. The baffles 3 on the front and rear sides are arranged outside the groove 6 and the slider 5. The slider 5 is symmetrically fixed on the outer walls of both ends of the fixed frame 8. The limiting effect of the groove 6 and the slider 5 makes it convenient to limit the fixed frame 8 and also facilitates the movement of the fixed frame 8 inside the device, which facilitates the subsequent movement of the adjusting plate 10. The baffles 3 can limit the slider 5 and the fixed frame 8 to prevent the positioning mechanism 4 from falling off.

[0023] In this embodiment, the fixing frame 8 is disposed between the left and right side plates 2. The adjusting screws 9 are symmetrically screwed into the inside of both ends of the fixing frame 8. The adjusting screws 9 are symmetrically rotated and disposed at the top of both ends of the adjusting plate 10. A handwheel is fixedly disposed at the top of the adjusting screws 9 corresponding to the top of the fixing frame 8. The bottom sides of the adjusting plate 10 are in close contact with the side walls of the left and right side plates 2. The adjusting plate 10 is disposed above the base plate 1. The height of the adjusting plate 10 can be easily adjusted by adjusting the adjusting screws 9 and the handwheel, which facilitates the control of the distance between the bottom of the adjusting plate 10 and the base plate 1, thereby positioning the top height of the composite precast slab and facilitating the control of the thickness of the composite precast slab.

[0024] In this embodiment, the limiting mechanism 11 further includes an inner groove 13, which is opened above the V-shaped groove 12 corresponding to the interior of the adjusting plate 10. The top end of the first square rod 14 is slidably installed inside the inner groove 13, and the top end of the second square rod 15 is slidably installed inside the bottom end of the first square rod 14. The first square rod 14 and the second square rod 15 are both "T" shaped. The bottom end of the second square rod 15 is fixedly set at the center of the top of the limiting plate 16. The limiting plate 16 is set inside the V-shaped groove 12. The inner groove 13 can limit the first square rod 14, and the first square rod 14 can conveniently limit the second square rod 15, so that the limiting plate 16 can only move up and down. The limiting plate 16 limits the steel truss through the groove, preventing it from falling during concrete pouring or vibration, and improving the stability of the steel truss.

[0025] When using this composite precast slab thickness positioning device, the side plates 2 are fixedly installed on the left and right ends of the base plate 1 with bolts 7. A corresponding number of positioning mechanisms 4 are installed between the two side plates 2 as needed. The sliders 5 at both ends of the fixed frame 8 are engaged inside the slide groove 6, facilitating the limiting of the positioning mechanism 4 by the sliders 5 and the slide groove 6. The baffles 3 are installed on the front and rear sides of the base plate 1 and the side plates 2 respectively with bolts 7. According to the required thickness of the composite precast slab, the handwheel and adjusting screw 9 are rotated. The adjusting screw 9 moves at both ends of the fixed frame 8, causing the adjusting plate 10 to slide inside the fixed frame 8. This facilitates adjustment of the distance between the bottom end face of the adjusting plate 10 and the base plate 1, allowing for positioning of the concrete pouring height by the bottom end face of the adjusting plate 10. The steel truss is placed on both sides above the base plate 1 and below the V-groove 12. When the adjusting plate 10 descends, it drives the V-groove 12 to descend as well. The limiting plate 16 contacts the top of the steel truss and engages the top of the steel truss inside the groove. Concrete is poured into the device, and the fixed frame 8 moves inside the device. The fixed frame 8 drives the adjusting plate 10 to move along the direction of the slide 6, which facilitates leveling the upper surface of the concrete and concentrates excess concrete to one side. Since the limiting plate 16 can only move up and down, it prevents it from shifting during concrete pouring or vibration, thereby improving the stability of the steel truss. It also facilitates the positioning and control of the thickness of the composite precast slab, making it convenient to manufacture composite precast slabs of different thicknesses as needed, and improving the practicality of the device.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
