Description

Technical Field

[0001] This utility model relates to the field of external wall reinforcement, and in particular to an external wall reinforcement device for precast concrete buildings. Background Technology

[0002] Precast concrete refers to concrete products made in a factory or on-site. Precast concrete is poured elsewhere rather than at the final construction site. Precast concrete of different sizes and shapes can be reinforced with fiber to enhance its reliability and toughness after cracking. Precast concrete buildings are constructed using various precast concrete structures, which are then reinforced with concrete, effectively improving the construction efficiency of buildings.

[0003] Most existing precast concrete building exterior wall reinforcement devices are equipped with fixed support bases. During use, after the precast building exterior wall is hoisted and initially fixed, the support and fixing devices are then erected to fix the precast concrete exterior wall. In most cases, the support only supports one side of the precast building exterior wall, which leads to a decrease in the effectiveness of the precast concrete building exterior wall reinforcement devices.

[0004] Therefore, addressing the issue that most existing precast concrete building exterior wall reinforcement devices are equipped with fixed support bases, requiring the installation of support and fixing devices after hoisting and initial fixing to secure the precast concrete exterior wall, and often only supporting one side of the precast building exterior wall, leading to a decrease in the effectiveness of the reinforcement device, a new precast concrete building exterior wall reinforcement device can be designed. This device uses a platform to determine the support position, and a second hydraulic push rod to move the positioning block. A mounting frame is used to install and rotate a rotating plate, which in turn drives the second threaded rod and the second clamping plate to rotate. A rotating joint and a rotating groove are used to rotate the covering tube, which, through the covering tube, the slot, and the locking block, moves the second threaded rod and the second clamping plate back and forth to cooperate with the positioning block in fixing the precast exterior wall.

The covering tube 27 and the rotating frame 21 are rotatably connected through the rotating joint 28 and the rotating groove 22. The rotating joint 28 is threadedly connected to the second threaded rod 24. The support position is determined by the platform body 1, and the positioning block 9 is moved by the second hydraulic push rod 8. The rotating plate 20 is installed and rotated by the mounting frame 10. The second threaded rod 24 and the second clamping plate 26 are rotated by the rotating plate 20 and the rotating frame 21. The covering tube 27 is rotated by the rotating joint 28 and the rotating groove 22, so that the second threaded rod 24 and the second clamping plate 26 can be moved back and forth through the covering tube 27, the locking groove 25 and the locking block 23.

[0023] Please see Figures 2-3In this embodiment, a mounting plate 2 is fixedly connected to the lower end of the platform body 1. First sliding grooves 3 are provided on both sides of the platform body 1, and a second sliding groove 4 is provided between the two first sliding grooves 3. A first hydraulic push rod 5 is installed at the front end of the second sliding groove 4. The platform body 1 is installed and fixed via the mounting plate 2 to adjust the support position and tilt angle. A movable platform 6 is installed at the rear end of the first hydraulic push rod 5. The movable platform 6 is slidably connected to the second sliding groove 4. Mounting seats 7 are installed on both sides of the movable platform 6. The mounting seats 7 are slidably connected to the first sliding groove 3. The first hydraulic push rod 5 drives the movable platform 6 and mounting seats 7 to move. A first rotating platform 11 is rotatably connected to the inner side of the mounting seat 7 via a rotating shaft. A first threaded rod 12 is installed at the upper end of the first rotating platform 11. The tilt angle of the first threaded rod 12 is installed and adjusted via the first rotating platform 11. A rotating tube 13 is connected to the side thread. The upper end of the rotating tube 13 is rotatably connected to a second rotating platform 14. The rear end of the second rotating platform 14 is rotatably connected to a positioning plate 15 via a rotating shaft. The rotating tube 13 is installed on the second rotating platform 14, and the distance between the first rotating platform 11 and the second rotating platform 14 is adjusted by the rotating tube 13 and the first threaded rod 12. A third hydraulic push rod 16 is installed on both sides of the positioning plate 15. A first clamping plate 17 is installed on the rear end of the third hydraulic push rod 16. The first clamping plate 17 is moved by the third hydraulic push rod 16 to clamp and position the precast exterior wall.

The distance between the positioning plate 15 and the positioning block 9 is adjusted by the support platform 19 and the support tube 18.

[0024] During installation, firstly, the second hydraulic push rod 8 is used to move the positioning block 9. Then, the rotating plate 20 and the rotating frame 21 are used to rotate the second threaded rod 24 and the second clamping plate 26 to align with the edge of the precast exterior wall. Then, the covering tube 27 is rotated to move the second threaded rod 24 and the second clamping plate 26 back and forth through the covering tube 27, the slot 25 and the clamping block 23, thereby using the second clamping plate 26 and the positioning block 9 to clamp and fix the lower end of the precast exterior wall. Finally, the lower end of the precast exterior wall is moved by the second hydraulic push rod 8 and the positioning block 9.

[0025] In use, firstly, the platform body 1 is installed and fixed by the mounting plate 2 to adjust the position and tilt angle of the support. Then, the moving platform 6 and the mounting base 7 are moved by the first hydraulic push rod 5. Next, the distance between the first rotating platform 11 and the second rotating platform 14 is adjusted by the rotating tube 13 and the first threaded rod 12. Then, the first clamping plate 17 is moved by the third hydraulic push rod 16 to clamp and position the precast exterior wall. Finally, the distance between the positioning plate 15 and the positioning block 9 is adjusted by the support platform 19 and the support tube 18. The position of the upper end of the precast exterior wall is finely adjusted by the rotating tube 13 and the first threaded rod 12 to adjust the overall tilt angle of the precast exterior wall in conjunction with the positioning block 9.

[0026] Through the above steps, the support position is determined by the platform body 1, and the positioning block 9 is moved by the second hydraulic push rod 8. The rotating plate 20 is installed and rotated by the mounting frame 10, and the second threaded rod 24 and the second clamping plate 26 are rotated by the rotating plate 20 and the rotating frame 21. The covering tube 27 is rotated by the rotating joint 28 and the rotating groove 22, so that the second threaded rod 24 and the second clamping plate 26 can be moved back and forth by the covering tube 27, the slot 25 and the locking block 23. This solves the problem that most existing concrete precast building exterior wall reinforcement devices are equipped with fixed support bases. During use, after hoisting and initial fixing, a support fixing device is erected to fix the precast concrete exterior wall, and most of them support only one side of the precast building exterior wall, which leads to a decrease in the effectiveness of the concrete precast building exterior wall reinforcement device.
