Description

Technical Field

[0001] This utility model relates to the field of assembly construction technology, specifically to a quick positioning and connection component for prefabricated structure construction. Background Technology

[0002] Chinese Patent CN221236442U discloses a rapid installation tool for prefabricated structures, belonging to the field of prefabricated wall panel installation technology. It includes a base with a support component on its surface, a support plate mounted on the side of the base, and an auxiliary component on the side of the support plate. This invention utilizes the support component, where a motor drives a screw to rotate. Under the meshing connection between the screw and a slider, the slider can move in a limited position. The slider can push the support plate against the support plate via a support rod on a rotating seat. The rotation of the support plate pushes the prefabricated wall panel, completing the rapid installation and improving the device's effectiveness. Furthermore, by using the auxiliary component, the rotating control rod, under the meshing connection between the control rod and a moving plate, slides and limits the movement between the fixed rod and the support plate. The moving plate can drive the fixed plate to move via a connecting seat. The fixed plate can press and position the prefabricated wall panel, making the movement of the prefabricated wall panel by the support plate more stable.

[0003] Commonly used rapid positioning and connection components for prefabricated structure construction generally suffer from low positioning accuracy and poor connection reliability. They often rely on manual adjustments, leading to low construction efficiency, and the lack of effective temporary fixing measures easily causes rebar displacement. Furthermore, insufficient sealing performance frequently results in grout leakage, affecting connection quality. The overall low level of automation also hinders the improvement of construction efficiency. Therefore, those skilled in the art provide a rapid positioning and connection component for prefabricated structure construction to solve the problems mentioned in the background art.

A stud 26 is fixedly connected to the center of the lower end of the bevel gear 25.

[0019] The support mechanism 2 is fixed to the corner of the positioning frame 1 by a movable frame post 21, and has a rotating post 22 and a bevel gear transmission mechanism inside. When the handle 24 is turned, the rotating post 22 drives the first bevel gear 23 to rotate, which in turn drives the second bevel gear 25 to rotate, driving the first stud 26 to rotate. The fixing plate 27 is used to fix the first stud 26 to ensure the stability of the adjustment process.

[0020] As one implementation method in this embodiment, please refer to Figure 2 As shown, a fixing plate 27 is fixedly connected inside the movable frame column 21 near the lower end of the bevel gear 25. The fixing plate 27 is sleeved on the upper end of the stud 26. A support base 28 is threaded on the outer side of the stud 26. A support foot 29 is fixedly connected to the lower end of the support base 28.

[0021] The threaded connection between stud 26 and support base 28 allows stud 26 to move up and down inside support base 28, which in turn drives the moving frame column 21 to move up and down, ultimately adjusting the height.

[0023] The upper end of the positioning frame 1 is provided with a guide post 31 and a top plate 32, forming a guide track. The motor 33 drives the stud 34 to rotate, which drives the positioning slider 35 to move up and down along the guide post 31, thereby realizing the height positioning adjustment of the component.

[0024] As one implementation method in this embodiment, please refer to Figure 4 As shown, the gripper assembly 4 includes a second motor 41, which is fixedly connected to the center of the positioning slider 35. The output end of the second motor 41 is fixedly connected to a rotating shaft 42. A main gear 43 is fixedly connected to the outer side of the rotating shaft 42. Three sector gears 44 are evenly meshed around the outer circumference of the main gear 43. A fixing post 45 is rotatably connected to the center of each of the three sector gears 44. The three fixing posts 45 are fixedly connected to the lower end of the positioning slider 35. A connecting post 46 is fixedly connected to the outer side of each of the three sector gears 44 near the main gear 43. A rubber clamping post 47 is fixedly connected to the lower end of each of the three connecting posts 46 away from the fixing post 45.

[0025] The gripper assembly 4 is driven by a motor 41 to rotate the rotating shaft 42 and the main gear 43. The main gear 43 drives three sector gears 44 to rotate synchronously. The sector gears 44 control the opening and closing of the rubber clamping posts 47 through the connecting posts 46, thereby clamping or releasing the steel reinforcement 5 of the component. The design of the rubber clamping posts 47 can firmly fix the component while avoiding damage to the surface of the steel reinforcement.

[0026] As one implementation method in this embodiment, please refer to Figure 5 As shown, the connecting assembly 6 includes a second fixing post 61, which is fixedly connected to the center of two opposing inner walls of the positioning frame 1. A connecting sleeve 62 is fixedly connected to the center of the second fixing post 61. A flared sleeve 63 is fixedly connected to the upper end of the connecting sleeve 62. A rubber sealing ring 64 is fixedly fitted on the outer surface of the connecting sleeve 62. A sealing end cap 65 is fitted on the lower end of the connecting sleeve 62. A grouting pipe 66 is fixedly connected to the lower side of the connecting sleeve 62.

[0027] The connecting assembly 6 is fixed to the center of the inner wall of the positioning frame 1 by the fixing post 61. The connecting sleeve 62 and the flared sleeve 63 are used to accommodate and guide the protruding reinforcing bars of the precast component. The rubber sealing ring 64 and the sealing end cap 65 ensure the sealing of the connection. The grouting pipe 66 is used to inject grouting material to fix the reinforcing bars. The cooperation of the locking pin 67, the locking head 68 and the locking ring 69 further enhances the stability of the reinforcing bar connection.

[0028] As one implementation method in this embodiment, please refer to Figure 5 As shown, a locking pin 67 is fitted at the center of the flared sleeve 63. One end of the locking pin 67 is fixedly connected to a locking head 68. A locking ring 69 is hung at the center of the locking head 68. The locking ring 69 is fitted at the center of the locking head 68 and the locking pin 67 away from the center of the locking head 68.

[0029] The locking pin 67 and locking head 68 inside the flared sleeve 63 are fixed by the locking ring 69, forming a mechanical locking structure. The locking ring 69 and locking pin 67 can temporarily fix the position of the reinforcing bars before grouting, which facilitates the subsequent grouting operation.

[0030] Working principle: First, the level of the positioning frame 1 is adjusted by the support mechanism 2. Rotating the handle 24 drives the bevel gear transmission mechanism, causing the stud 26 to move the support base 28 up and down, thus adjusting the overall height of the device. When the motor 33 starts, it drives the stud 34 to rotate, causing the positioning slider 35 to move along the guide post 31, adjusting the component to the preset height. Then, the motor 41 is started, and through the meshing transmission of the main gear 43 and the sector gear 44, the rubber clamping post 47 clamps the reinforcing steel bar 5 of the component, ensuring the component is firmly fixed.

[0031] The protruding reinforcing bars of the precast component are inserted into the flared sleeve 63 of the connecting assembly 6. The position of the reinforcing bars is temporarily fixed using locking pins 67 and locking rings 69 to prevent loosening. Grouting material is injected through the grouting pipe 66, and a permanent connection is formed after the grout solidifies. Rubber sealing rings 64 and sealing end caps 65 ensure the seal at the connection point, preventing grout leakage. The entire construction process is highly efficient and precise, with reliable connections and simple operation, significantly improving the positioning and connection efficiency of prefabricated structures. It is widely applicable to various prefabricated building construction scenarios.

[0032] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
