Description

Technical Field

[0001] This application relates to the field of prefabricated building technology, and in particular to a prefabricated beam positioning device. Background Technology

[0002] Precast beams are made in a factory and then transported to the construction site for installation and fixing according to the design requirements. During the installation of precast beams, a hoisting device places the precast beam between two support columns, and then the precast beam and the support columns are rigidly connected by the concrete pouring process to build a stable load-bearing system. However, in current construction, the positioning of precast beams is mainly based on the placement lines pre-drawn on the top surface of the support columns. This rough positioning method relies on the experience of workers to make judgments. In actual construction, the placement position of the precast beams is prone to deviation, resulting in misalignment of the connection surface between the precast beams and the support columns, reducing the overall stability and load-bearing capacity of the structure, which is obviously insufficient. Utility Model Content

[0003] To reduce the possibility of misalignment of precast beams during hoisting and placement, this application provides a precast beam positioning device.

[0004] The precast beam positioning device provided in this application adopts the following technical solution: A precast beam positioning device includes two opposing support columns, on which a precast beam is mounted. A frame is positioned between the two support columns, and a bearing plate is mounted on the frame. The surface of the bearing plate is flush with the end face of the support column. A first limiting component and a second limiting component are mounted on the bearing plate. The first limiting component includes limiting plates arranged opposite each other along the width direction of the support columns. The second limiting component includes a locking post. A locking groove is formed at the center of the precast beam to engage with the locking post. A receiving groove is formed at the center of the bearing plate to slide with the locking post. An elastic element is provided in the receiving groove to drive the locking post into the locking groove.

[0005] By adopting the above technical solution, when hoisting the precast beam, workers place the precast beam in the space between two limiting plates, allowing the precast beam to descend along the limiting plates onto the support column, thereby achieving positioning of the precast beam in the width direction. Subsequently, the hoisting device moves the precast beam between the two limiting plates. When the locking column moves to be aligned with the locking groove, the elastic element drives the locking column to insert into the locking groove in the center of the precast beam, thereby achieving positioning of the precast beam in the length direction. Finally, the precast beam and the support column are connected through concrete pouring. This setup achieves dual positioning of the precast beam in both the length and width directions, improves the stability of the precast beam connection, reduces the possibility of positional displacement during the hoisting and assembly of the precast beam, and improves the structural strength of the precast beam and support column system.

[0006] Optionally, the support plate is provided with an adjustment assembly. The support plate has an adjustment groove and a guide groove respectively opened on opposite sides along its length. The adjustment assembly includes a bidirectional lead screw rotatably connected in the adjustment groove, a guide rod provided in the guide groove, one end of each of the two limiting plates being threadedly connected to two sections of the bidirectional lead screw with opposite thread directions, and the other end being slidably connected to the guide rod. The support plate is provided with an adjustment motor that drives the bidirectional lead screw to rotate.

[0007] By adopting the above technical solution, when it is necessary to position precast beams of different widths, the worker starts the adjusting motor to drive the bidirectional lead screw to rotate. Under the guidance and limit of the guide rod, the bidirectional lead screw drives the two limit plates to move synchronously towards or away from each other along the guide rod, thereby realizing the adjustment of the distance between the two limit plates to adapt to the width of different precast beams and improving the applicability of the positioning device.

[0008] Optionally, each of the limiting plates is provided with a guide plate, which is inclined from top to bottom in a direction close to the central axis of the bearing plate.

[0009] By adopting the above technical solution, when the precast beam descends to the limiting plate area during hoisting, the guide plate first contacts the precast beam. The guide slope on the guide plate can guide the precast beam to move and adjust towards the central axis of the bearing plate when the precast beam has a slight lateral deviation, so that the precast beam can smoothly enter the space between the two limiting plates, thereby reducing the risk of collision between the precast beam and the limiting plate during hoisting.

[0010] Optionally, the support plate is provided with a movable groove, and multiple conveying rollers are rotatably connected to the movable groove along its length.

[0011] By adopting the above technical solution, the conveyor roller can convert the sliding friction between the precast beam and the bearing plate into rolling friction, reduce the resistance when the precast beam moves on the bearing plate, reduce the difficulty of position adjustment caused by excessive friction, and improve the efficiency of positioning operation.

[0012] Optionally, the inner wall of the receiving groove is provided with a limiting groove, and the outer surface of the locking post is provided with a limiting ring that slides with the limiting groove. The elastic element is a locking spring sleeved on the outer surface of the locking post. One end of the locking spring is provided on the inner wall of the receiving groove, and the other end is provided on the limiting ring. The elastic force of the pressing spring drives the locking post to insert into the locking groove.

[0013] By adopting the above technical solution, the sliding cooperation between the limiting block and the limiting groove can restrict the movement trajectory of the locking column, so that the locking column can only move in a straight line along the axial direction of the receiving groove, avoiding the locking column from shifting, tilting or rotating during the extension and retraction process, and ensuring that the locking column can be accurately inserted into the locking groove of the precast beam.

[0014] Optionally, lifting cylinders are provided on both opposite sides of the frame, and the piston rods of the lifting cylinders are all mounted on the support plate, which is slidably connected to the frame.

[0015] By adopting the above technical solution, before hoisting, the lifting cylinder drives the surface of the bearing plate to move to a height that is flush with the end face of the support column. After the precast beam is placed, the lifting cylinder drives the bearing plate to descend. The descent of the bearing plate causes the guide plate to move to a height lower than the end face of the support column. Then, the workers push the frame out of the range of the support column, freeing up sufficient operating space for subsequent construction and effectively avoiding the cumbersome process of traditional positioning devices needing to be removed before pouring can be carried out.

[0016] Optionally, the bottom end of the frame is provided with rollers, and multiple fixing components are provided on the frame, which are mounted on the support column through the fixing components.

[0017] By adopting the above technical solution, during the construction preparation stage, the frame is conveniently pushed to the predetermined position between two support columns by rollers. Then, the frame is fixed by fixing components to reduce the displacement or shaking of the frame caused by external forces, ensuring that the first and second limiting components can stably perform their positioning functions and guaranteeing the positioning accuracy of the precast beam.

[0018] Optionally, the fixing assembly includes a fixing sleeve rotatably connected to the outer surface of the frame, a fixing plate slidably connected inside the fixing sleeve, a limit post provided on the outer surface of the support column, the limit post having a T-shaped cross-section, a hook groove provided on the fixing plate to engage with the limit post, and a return spring provided inside the fixing sleeve, the return spring driving the fixing plate to move into the fixing sleeve.

[0019] By adopting the above technical solution, after the frame is pushed between the two support columns, the worker overcomes the elastic force of the return spring and pulls the fixing plate outward along the fixing sleeve, and makes the hook groove hook the limiting column. Finally, the fixing plate is released, and under the action of the return spring, the fixing plate moves into the fixing sleeve, thereby tightly hooking the limiting column and fixing the frame firmly on the support column, effectively preventing the frame from shifting or shaking during the hoisting, positioning and concrete pouring of precast beams.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. In this embodiment, by setting a first limiting component and a second limiting component, when hoisting a precast beam, the worker places the precast beam in the space between the two limiting plates, so that the precast beam descends along the limiting plates to the support column, thereby achieving the positioning of the precast beam in the width direction. Subsequently, the hoisting device drives the precast beam to move between the two limiting plates. When the locking column moves to be directly opposite the locking groove, the elastic element drives the locking column to insert into the locking groove in the center of the precast beam, thereby achieving the positioning of the precast beam in the length direction. Finally, the precast beam and the support column are connected by the concrete pouring process. This setting achieves dual positioning of the precast beam in both the length and width directions, improves the stability of the precast beam connection, reduces the possibility of positional displacement during the hoisting and assembly of the precast beam, and improves the structural strength of the precast beam and support column system. 2. In this embodiment of the application, by setting an adjustment component, when it is necessary to position precast beams of different widths, the worker starts the adjustment motor to drive the bidirectional lead screw to rotate. Under the guidance and limit of the guide rod, the bidirectional lead screw drives the two limit plates to move synchronously towards or away from each other along the guide rod, thereby realizing the adjustment of the distance between the two limit plates, so as to adapt to the width of different precast beams and improve the applicability of the positioning device. 3. In this embodiment of the application, by setting a fixing component, the frame is fixed by the fixing component, which reduces the displacement or shaking of the frame caused by external forces, and ensures that the first limiting component and the second limiting component can stably perform their positioning functions, thus ensuring the positioning accuracy of the precast beam.

Detailed Implementation

[0026] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0027] This application discloses a precast beam positioning device.

[0028] Reference Figure 1 and Figure 2 A precast beam positioning device includes two opposing support columns 01 installed on the ground. A precast beam 02 is installed on the support columns 01. A frame 1 is arranged between the two support columns 01. Rollers 101 are installed at the bottom of both opposite ends of the frame 1. The rollers 101 abut against the ground. Fixing components 2 are installed at the four corners of the outer surface of the frame 1.

[0029] Reference Figure 1 and Figure 2 The fixing component 2 includes a fixing sleeve 21 rotatably connected to the outer surface of the frame 1. A fixing plate 22 is slidably connected inside the fixing sleeve 21. A limiting post 23 is fixedly installed on the outer surface of the support column 01. The cross-section of the limiting post 23 is T-shaped. The end of the fixing plate 22 extending out of the fixing sleeve 21 is provided with a hook groove 231 that hooks and engages with the limiting post 23. A return spring 24 is provided inside the fixing sleeve 21. One end of the return spring 24 is fixedly connected to the inner side wall of the fixing sleeve 21, and the other end is fixedly connected to the fixing plate 22.

[0030] Before assembly, the worker pushes the frame 1 between the two support columns 01 using roller 101. Then, the worker overcomes the elastic force of the return spring 24 and pulls the four fixing plates 22 outward along the fixing sleeve 21 in sequence, so that the hook groove 231 hooks the limiting column 23. Finally, the fixing plates 22 are released. Under the action of the return spring 24, the fixing plates 22 move into the fixing sleeve 21, thereby tightly hooking the limiting column 23. With the fixing of the four fixing components 2, the frame 1 is stabilized on the support column 01.

[0031] Reference Figure 1 , Figure 3 and Figure 4 Lifting cylinders 3 are embedded on both sides of the frame 1. The piston rod of the lifting cylinder 3 is fixedly connected to the bearing plate 4. The bearing plate 4 is slidably connected in the vertical direction of the frame 1. The bearing plate 4 is provided with a first limiting component 5 and a second limiting component 6. The first limiting component 5 includes a limiting plate 51 arranged opposite to each other along the width direction of the support plate. Each limiting plate 51 is integrally formed with a guide plate 52. The guide plate 52 is inclined from top to bottom in the direction close to the central axis of the bearing plate 4.

[0032] Reference Figure 3 and Figure 4 The second limiting component 6 includes a locking post 61. A locking groove 021 is provided at the center of the precast beam 02 to engage with the locking post 61. The end faces of the locking post 61 and the locking groove 021 are both arc-shaped. A receiving groove 41 is provided at the center of the bearing plate 4 to slide with the locking post 61. A limiting groove 42 is provided on the inner side wall opposite to the receiving groove 41. A limiting ring 611 is fixedly connected to the outer surface of the locking post 61 to slide with the limiting groove 42.

[0033] Reference Figure 3 and Figure 4 An elastic element 62 is provided inside the receiving groove 41. The elastic element 62 is a locking spring sleeved on the outer surface of the locking post 61. One end of the locking spring is fixedly connected to the inner side wall of the receiving groove 41, and the other end is fixedly connected to the outer surface of the locking post 61. The elastic force of the spring drives the locking post 61 to be inserted into the locking groove 021.

[0034] Reference Figure 3 and Figure 4 The surface of the support plate 4 is provided with a moving groove 43. Multiple conveying rollers 431 are rotatably connected in the moving groove 43 along the length direction. The cut surface of the top of the conveying roller 431 is flush with the surface of the support plate 4. The friction between the precast beam 02 and the support plate 4 is reduced by the conveying rollers 431.

[0035] After the frame 1 is fixed, the lifting cylinder 3 is activated to drive the surface of the bearing plate 4 to move to a height that is flush with the end face of the support column 01. Then, the hoisting device lifts the precast beam 02 and transfers it between the two guide plates 52. Under the guidance of the guide slope of the guide plate 52, the precast beam 02 descends into the space between the two limiting plates 51, so that the precast beam 02 descends along the limiting plate 51 onto the support column 01, thereby achieving the positioning of the precast beam 02 in the width direction. Subsequently, the hoisting device moves the precast beam 02 between the two limiting plates 51. When the locking post 61 moves to be directly opposite the locking groove 021, the locking spring drives the locking post 61 to insert into the locking groove 021 in the center of the precast beam 02, thereby achieving the positioning of the precast beam 02 in the length direction. Finally, the precast beam 02 and the support column 01 are connected by the concrete pouring process. This setting achieves dual positioning of the precast beam 02 in both length and width directions, improves the stability of the precast beam 02 during connection, reduces the possibility of positional displacement during the hoisting and assembly of the precast beam 02, and improves the structural strength of the precast beam 02 and support column 01 system. After the concrete is poured, the lifting cylinder 3 is activated and drives the bearing plate 4 to descend. The bearing plate 4 drives the guide plate 52 to descend to a height lower than the end face of the support column 01. Then, the worker cancels the fixing function of the fixing component 2 and pushes the frame 1 out between the two support columns 01 through the roller 101, freeing up sufficient operating space for subsequent construction and effectively avoiding the cumbersome process of traditional positioning devices needing to be removed before pouring.

[0036] Reference Figure 3 and Figure 4 An adjustment assembly 7 is provided on the support plate 4. An adjustment groove 44 and a guide groove 45 are respectively opened on opposite sides of the support plate 4 along the length direction. The adjustment groove 44 and the guide groove 45 are parallel to the width direction of the support plate 4. The adjustment assembly 7 includes a bidirectional lead screw 71 rotatably connected in the adjustment groove 44. A guide rod 72 is fixedly installed in the guide groove 45. One end of two limit plates 51 is threaded to the two sections of the bidirectional lead screw 71 with opposite thread directions, and the other end is slidably connected to the guide rod 72. An adjustment motor 73 is fixedly installed on the outer surface of the support plate 4. The output shaft of the adjustment motor 73 is coaxially fixedly connected to the bidirectional lead screw 71.

[0037] When it is necessary to position precast beams 02 of different widths, the worker starts the adjusting motor 73 to drive the bidirectional lead screw 71 to rotate. Under the guidance and limit of the guide rod 72, the bidirectional lead screw 71 drives the two limit plates 51 to move synchronously towards or away from each other along the guide rod 72, thereby realizing the adjustment of the distance between the two limit plates 51 to adapt to the width of different precast beams 02 and improve the applicability of the positioning device.

[0038] The implementation principle of the precast beam positioning device in this application embodiment is as follows: After the frame 1 is fixed, the lifting cylinder 3 is activated to drive the surface of the bearing plate 4 to move to a height that is flush with the end face of the support column 01. Then, the hoisting device lifts the precast beam 02 and transfers it between the two guide plates 52. Under the guidance of the guide slope of the guide plate 52, the precast beam 02 descends into the space between the two limiting plates 51, so that the precast beam 02 descends along the limiting plate 51 onto the support column 01, thereby realizing the positioning of the precast beam 02 in the width direction. Subsequently, the hoisting device moves the precast beam 02 between the two limiting plates 51. When the locking post 61 moves to be directly opposite the locking groove 021, the locking spring drives the locking post 61 to insert into the locking groove 021 in the center of the precast beam 02, thereby achieving the positioning of the precast beam 02 in the length direction. Finally, the precast beam 02 and the support column 01 are connected by the concrete pouring process. This setting achieves dual positioning of the precast beam 02 in both length and width directions, improves the stability of the precast beam 02 during connection, reduces the possibility of positional deviation during the hoisting and assembly of the precast beam 02, and improves the structural strength of the precast beam 02 and support column 01 system.
