[0001] This utility model belongs to the field of prefabricated building technology, specifically a quick positioning and installation fixture for prefabricated components of prefabricated buildings. Background Technology

[0002] As a key tool in the installation of prefabricated components, the rapid positioning and installation fixture plays a crucial role in solving the efficiency and accuracy problems of prefabricated beams, columns, slabs, walls and other components during hoisting, alignment and fixing, directly serving the on-site construction process of prefabricated buildings.

[0003] However, the following problems were found in the implementation of the relevant technologies: Existing quick positioning and installation clamps for prefabricated components in prefabricated buildings mostly lack fine-tuning functions after clamping, or adjust the position by directly pushing the component, which easily causes the clamp to loosen or shift, making it difficult to meet the requirements of high-precision splicing. In addition, existing clamps have limited functions and are often only suitable for plate-shaped or tubular components. When changing the type of component, the clamps need to be changed frequently, resulting in poor versatility and affecting construction efficiency and cost control. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 4 As shown, this utility model provides a quick positioning and installation fixture for prefabricated components of a modular building, including a support plate 1. A plate-shaped fixing plate 2 and a tubular fixing plate 3 are slidably disposed on the upper surface of the support plate 1, and the plate-shaped fixing plate 2 and the tubular fixing plate 3 are fixedly connected. Grooves 4 are symmetrically formed inside the support plate 1, and gears 41 are rotatably disposed within the grooves 4. A connecting column 42 is fixedly connected through the two gears 41. A handle 43 is rotatably disposed on one side of the support plate 1. One end of the connecting column 42 passes through the support plate 1 and is fixedly connected to the handle 43. A toothed plate 44 is meshed with the upper surface of the outer surface of the gears 41. Furthermore, the upper surfaces of the two toothed plates 44 are fixedly connected to the plate-shaped fixing plate 2 and the tubular fixing plate 3, respectively. When the component is clamped, if it is necessary to finely adjust the position of the component (such as adjusting the lateral position of the component in the installation coordinate system), the handle 43 can be rotated, and the two gears 41 will be driven to rotate synchronously through the connecting column 42. The gears 41 mesh with the toothed plates 44, causing the toothed plates 44 to slide along the slide groove 45, thereby driving the plate-shaped fixing plate 2 and the tubular fixing plate 3, which have clamped the component, to move synchronously on the support plate 1 (the relative positions of the two remain unchanged), so as to achieve precise fine-tuning of the position of the clamped component and ensure alignment with the installation reference.

[0018] Specifically, a fixing clamp 21 is fixedly provided on one side of the upper surface of the plate-shaped fixing plate 2, and a side plate 22 is fixedly provided on the other side of the upper surface of the plate-shaped fixing plate 2. A lead screw 23 is threaded through one side of the side plate 22, and a turntable 24 is fixedly provided at the outer end of the lead screw 23. A movable clamp 25 is rotatably provided at the inner end of the lead screw 23. For the plate-shaped component, it is placed on the plate-shaped fixing plate 2, with one side attached to the fixing clamp 21. Rotating the turntable 24 causes the lead screw 23 to push the movable clamp 25 to move towards the fixing clamp 21, thereby achieving clamping and fixing.

[0019] Furthermore, a U-shaped block 31 is fixedly provided on the upper surface of the tubular fixing plate 3, and a bracket 32 ​​is fixedly provided on the upper surface of the U-shaped block 31. A threaded rod 33 is threaded through the upper surface of the bracket 32. A knob 34 is fixedly provided at the upper end of the threaded rod 33, and a pressure block 35 is rotatably provided at the lower end of the threaded rod 33. The pressure block 35 is locked in the bracket 32. For tubular components, they are placed in the bracket 32, and the knob 34 is rotated to make the threaded rod 33 move the pressure block 35 downward to complete the clamping.

[0020] Furthermore, the upper surface of the support plate 1 is symmetrically provided with sliding grooves 45, and the toothed plate 44 is slidably disposed in the corresponding sliding groove 45. The toothed plate 44 slides along the sliding groove 45, and the sliding groove 45 improves the stability of the movement of the toothed plate 44.

[0021] It is worth noting that a positioning post 27 is fixedly provided on the outer side of the movable clamping plate 25, and the positioning post 27 penetrates the side plate 22 to prevent displacement.

[0022] It is worth noting that sliders 26 are symmetrically fixed on the lower surface of the movable clamping plate 25, and the sliders 26 are locked on the plate-shaped fixing plate 2, so as to ensure translational stability.

[0023] It is worth mentioning that the lower surface of the pressure block 35 and the lower inner wall of the bracket 32 ​​are symmetrically provided with arc-shaped grooves 36. The pressure block 35 and the lower inner wall of the bracket 32 ​​are used to fit against the surface of the tubular component to complete the clamping. Working principle: For plate-shaped components, place them on the plate-shaped fixing plate 2, with one side attached to the fixing clamping plate 21. Rotate the turntable 24 to make the lead screw 23 push the moving clamping plate 25 to move towards the fixing clamping plate 21. The clamping and fixing are achieved through the slider 26 (to ensure translational stability) and the positioning column 27 (to prevent displacement). For tubular components, place them inside the bracket 32, turn the knob 34 to make the threaded rod 33 move the pressure block 35 down, and use the arc groove 36 on the lower inner wall of the bracket 32 ​​to fit the surface of the tubular component to complete the clamping. Once the component is clamped, if fine adjustments to its position are needed (such as adjusting the lateral position of the component in the installation coordinate system), the handle 43 can be rotated. This will drive the two gears 41 to rotate synchronously via the connecting column 42. The gears 41 mesh with the toothed plate 44, causing the toothed plate 44 to slide along the slide groove 45. This, in turn, causes the plate-shaped fixing plate 2 and the tubular fixing plate 3 of the clamped component to move synchronously on the support plate 1 (their relative positions remain unchanged), thus achieving precise fine-tuning of the clamped component's position and ensuring alignment with the installation reference.
