[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.
[0022] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.
[0023] Embodiment 1, as Figures 1 - 4 shown, the present utility model provides a concrete precast building exterior wall reinforcement device, including a base 1. A plurality of insertion rods 2 are fixedly connected to the bottom of the base 1. Two first sliding grooves 3 are opened at the top of the base 1. First sliders 4 are slidably embedded in the inner walls of the two first sliding grooves 3. Two connecting plates 5 are fixedly connected between the inner walls of the base 1. First threaded grooves 6 are opened on one side of the outer walls of the two connecting plates 5. First adjusting screws 7 are threadedly connected to the inner walls of the two first threaded grooves 6. First bearings 8 are fixedly sleeved on the outer surfaces of the two first adjusting screws 7. A first reinforcement plate 9 is fixedly sleeved between the outer surfaces of the two first bearings 8. One side of the outer wall of the two first sliders 4 is fixedly connected to one side of the outer wall of the first reinforcement plate 9. Three telescopic plates 10 are movably inserted into the inner wall of the base 1. A fixing plate 11 is fixedly connected between the tops of the three telescopic plates 10. Three second threaded grooves 12 are opened on one side of the outer wall of the fixing plate 11. Second adjusting screws 13 are threadedly connected to the inner walls of the three second threaded grooves 12. Second bearings 14 are fixedly sleeved on the outer surfaces of the two second adjusting screws 13. Three groups of second sliding grooves 15 are opened at the bottom of the fixing plate 11. Second sliders 16 are slidably embedded in the inner walls of the three groups of second sliding grooves 15. Rack bars 17 are fixedly connected to the bottoms of the three groups of second sliders 16.
[0024] The overall effect achieved by the entire Embodiment 1 is as follows. First, place the reinforcement device at a specific position on the building exterior wall to ensure that the distances between the two second reinforcement plates 21 and both sides of the exterior wall are the same. Subsequently, rotate the three second adjusting screws 13 respectively. Since the outer surfaces of the three second bearings 14 are fixedly inserted into the interiors of three of the three groups of second reinforcement plates 21, the rotation of the second adjusting screw 13 drives a second reinforcement plate 21 to move horizontally. The movement of this second reinforcement plate 21 drives a rack bar 17 to move synchronously. Since there is an engaging transmission between the two rack bars 17 and the gear 18, the movement of one rack bar 17 causes the other rack bar 17 to move in the opposite direction, thereby clamping the exterior wall with a group of second reinforcement plates 21. By rotating the three second adjusting screws 13 respectively, all three groups of second reinforcement plates 21 can firmly clamp the exterior wall, effectively fixing both sides of the exterior wall. Moreover, this reinforcement method greatly simplifies the installation process, reduces the steps and tools required during installation, thus facilitating the operation of construction workers and improving construction efficiency. At the same time, its adjustability and flexibility also enable the device to meet the reinforcement requirements for exterior walls of different thicknesses.
[0025] Embodiment 2, as shown in Figures 2 - 4 As shown, gear 18 is meshed and connected between the outer walls of the three groups of racks 17. The inner walls of the three gears 18 are fixedly inserted with rotating shafts 19. The outer walls of the three rotating shafts 19 are fixedly sleeved with third bearings 20. Two second reinforcing plates 21 are slidably embedded between the inner walls of the three groups of second chutes 15. And one side of the outer walls of the three groups of racks 17 is fixedly connected to one side of the outer walls of the three groups of second reinforcing plates 21. One group of third threaded grooves 22 is opened on one side of the outer walls of the three telescopic plates 10. The inner walls of the three groups of third threaded grooves 22 are threadedly connected with fixing bolts 23.
[0026] The overall effect achieved by the entire Embodiment 2 is that when the height of the reinforcement device is inconsistent with the height of the exterior wall of the precast concrete building, first loosen the three fixing bolts 23 to release the fixed state of the three telescopic plates 10. Then move the height of the fixing plate 11. When the height reaches the appropriate position, screw the three fixing bolts 23 into the corresponding three third threaded grooves 22 to re-fix the telescopic plates 10, so that the reinforcement device can adapt to the actual height of the exterior wall and ensure an effective reinforcement effect.
[0027] Working principle: During use, first, the vertical position of the fixing plate 11 needs to be finely adjusted according to the height of the exterior wall. By the staff loosening the three fixing bolts 23, the locking state of the telescopic plate 10 is released. Then, flexibly adjust the fixing plate 11 to an appropriate height to ensure that it meets the reinforcement requirements. Once the height is determined, immediately tighten the three fixing bolts 23 into the corresponding third threaded grooves 22 to achieve the stable locking of the fixing plate 11. Subsequently, place the entire reinforcement device accurately at the preset position on the exterior wall of the building, ensuring that the second reinforcing plates 21 on both sides are equidistant from the surface of the exterior wall to achieve a uniform force distribution. Then, use multiple insertion rods 2 to penetrate into the soil around the exterior wall to form stable anchoring points, so as to ensure that the entire reinforcement device is firmly fixed to the ground. After the fixing device is stable, the operator rotates the three second adjusting screws 13. By using their precise thread fit with the second threaded grooves 12, a second reinforcing plate 21 is driven to move precisely in the horizontal direction. This movement will synchronously drive a rack 17 to move. And through the meshing transmission mechanism of the two racks 17 and the central gear 18, it is ensured that the movement of one rack 17 will drive the other rack 17 in the opposite direction, so as to realize the synchronous and reverse adjustment of the second reinforcing plates 21 on both sides, closely and evenly fitting on both sides of the exterior wall to provide an effective reinforcement effect. By rotating the three second adjusting screws 13 respectively, it can be ensured that the three groups of second reinforcing plates 21 can firmly clamp the exterior wall from both sides, significantly improving the overall structural strength and stability of the exterior wall. In addition, by using the thread fit of the two first adjusting screws 7 and the first threaded grooves 6, rotating the first adjusting screw 7 can make the first reinforcing plate 9 closely adhere to and be fixed on one side of the exterior wall of the building, further enhancing the reinforcement effect and providing comprehensive protection and support for the exterior wall.
[0028] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution content of the present utility model still fall within the protection scope of the technical solution of the present utility model.
