Description

Technical Field

[0001] This utility model relates to the field of reinforced structure technology, specifically a combined reinforced structure for precast shear walls with large openings. Background Technology

[0002] Shear walls, also known as wind-resistant walls, earthquake-resistant walls, or structural walls, are walls in buildings or structures that primarily bear horizontal and vertical loads caused by wind or earthquakes, preventing structural shear failure. Planar shear walls are used in reinforced concrete frame structures, lift-slab structures, and flat slab systems. To increase the stiffness, strength, and collapse resistance of the structure, reinforced concrete shear walls can be cast-in-place or precast in certain locations.

[0003] In the process of realizing this utility model, the inventors discovered the following unresolved problems in the prior art: the existing combined reinforcement structure for precast shear walls with large openings requires the pre-embedding of corresponding hook mechanisms in the shear wall, and the same applies to the shear wall with openings. However, the shear wall with openings has the function of connecting and adjusting with the reinforcement structure, and the corresponding pre-embedded hook mechanism is still set on it, which not only causes unnecessary costs, but also makes later cutting and removal troublesome, and urgently needs to be improved. Therefore, we propose a combined reinforcement structure for precast shear walls with large openings. Utility Model Content

[0004] The purpose of this invention is to provide a combined reinforcement structure for precast shear walls with large openings, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined reinforcement structure for precast shear walls with large openings, comprising a concrete layer, a shear wall placed on top of the concrete layer, and a baffle placed on one side of the shear wall;

[0006] Several sets of uniformly arrayed steel bars are fixedly installed on the top of the concrete layer, and a pre-embedded hanging ring is fixedly installed on one side of the concrete layer.

[0007] The bottom of the shear wall has a steel bar groove on the outer side near the steel bar, and the top of the shear wall has an opening integrally formed.

[0008] A support block is fixedly installed on one side of the baffle, and a support rod is placed on one side of the support block. The support rod is rotatably connected to the support block through bearing a. A reinforcing rod is placed on one side of the support rod, and the support rod is rotatably connected to the reinforcing rod through a hinge.

[0009] The bottom end of the reinforcing rod is equipped with a hook, which is hooked onto a pre-embedded hanging ring. The hook extends through one side of the reinforcing rod, and a screw block is fixedly installed inside the hook.

[0010] The reinforcing rod has an opening, into which a screw is placed. The screw is rotatably connected to the reinforcing rod via a bearing b. The other end of the screw is screwed into a pre-set threaded groove in the screw block via an external thread. It can be used in conjunction with components such as a baffle, reinforcing rod, and hook. During the assembly and reinforcement of the structure, the reinforcing rod can be passed through the opening, and the baffle can be attached to one side of the shear wall. Then, the hook is attached to the pre-embedded hanging ring. Subsequently, the screw is rotated by personnel, which can drive the screw block to move until the reinforcing rod is tensioned on one side of the shear wall. Compared with the existing method, when reinforcing the open-type shear wall, there is no need to pre-set a corresponding hook mechanism on the shear wall, which indirectly reduces the cost of the reinforcing rib.

[0011] As an optional solution to the technical solution of this application, threaded cylinders are fixedly installed on both sides of the bottom of the support block. A threaded column is screwed into the middle of the threaded cylinder through an internal thread. A limiting plate is fixedly installed on the outer end of the threaded column. The threaded cylinder and the threaded column can be used together to maximize the proximity of the baffle to the middle of the shear wall when placing the baffle. Then, the threaded column is rotated to adjust the position of the limiting plates on both sides so that the limiting plates fit against the side wall of the opening in the shear wall. This is used to center and limit the baffle to prevent the baffle from shifting and has the desired strengthening effect.

[0012] As an optional solution to the technical solution of this application, rubber pads are fixedly installed on the outer side of the limiting plate and one side of the baffle, and anti-slip textures are provided on the rubber pads. The rubber pads can contact the shear wall to prevent excessive wear defects during the connection reinforcement process.

[0013] As an optional solution to the technical solution of this application, a through hole is provided in the middle of the screw, and the diameter of the through hole is two centimeters. The through hole allows personnel to insert a rod-like object, and the personnel use the rod-like object to drive the screw to rotate, which facilitates force adjustment.

[0014] As an optional solution to the technical solution of this application, the height of the opening is less than the height of the baffle, so that the baffle can completely cover the outside of the opening, which meets the positioning requirements of this utility model.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model discloses a combined reinforcement structure for precast shear walls with large openings. By setting up a baffle, a reinforcing rod, and a hook, during the combined reinforcement process, the reinforcing rod is passed through the opening, and the baffle is attached to one side of the shear wall. Then, the hook is hooked onto a pre-embedded hanging ring. Subsequently, a person applies force to rotate the screw, which drives the screw block to move until the reinforcing rod is tensioned on one side of the shear wall. Compared with the existing method, when reinforcing open-type shear walls, there is no need to pre-set a corresponding hooking mechanism on the shear wall, indirectly reducing the cost of reinforcing ribs.

[0017] 2. This utility model discloses a combined reinforcement structure for precast shear walls with large openings. By setting threaded cylinders and threaded columns, when placing the baffle, the baffle is placed as close as possible to the center of the shear wall. Then, the threaded columns are rotated to adjust the position of the limiting plates on both sides, so that the limiting plates fit against the side wall of the opening in the shear wall, which is used to center and limit the baffle to prevent the baffle from shifting, and has the desired reinforcement effect.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figure 1-3This utility model provides a technical solution: a combined reinforcement structure for precast shear walls with large openings, including a concrete layer 1, a shear wall 2 placed on top of the concrete layer 1, and a baffle 3 placed on one side of the shear wall 2; several sets of uniformly arrayed steel bars 12 are fixedly installed on the top of the concrete layer 1, and a pre-embedded hanging ring 11 is fixedly installed on one side of the concrete layer 1; a steel bar groove is opened on the outer side of the bottom of the shear wall 2 near the steel bars, and an opening 21 is integrally formed on the top of the shear wall 2, the height of the opening 21 being less than the height of the baffle 3, so that the baffle 3 can completely cover the outside of the opening 21, meeting the positioning requirements of this utility model; a support block 31 is fixedly installed on one side of the baffle 3, and a support rod 34 is placed on one side of the support block 31, the support rod 34 being connected to the support through a bearing a32. Block 31 is rotatably connected. A reinforcing rod 4 is placed on one side of the support rod 34, and the support rod 34 is rotatably connected to the reinforcing rod 4 through the hinge 33. A hook 5 is installed at the bottom of the reinforcing rod 4, and the hook 5 is hooked on the pre-embedded hanging ring 11. The hook 5 moves through one side of the reinforcing rod 4, and a screw block 51 is fixedly installed inside the hook 5. An opening 41 is opened inside the reinforcing rod 4, and a screw 43 is placed inside the opening 41. The screw 43 is rotatably connected to the reinforcing rod 4 through the bearing b42. The other end of the screw 43 is screwed into the pre-set thread groove 52 inside the screw block 51 through the external thread. A through hole with a diameter of two centimeters is opened in the middle of the screw 43. The through hole allows personnel to insert rod-shaped objects. Personnel use rod-shaped objects to drive the screw 43 to rotate, which is convenient for applying force and adjustment.

[0025] In this technical solution, components such as baffle 3, reinforcing rod 4, and hook 5 can be used together. During the reinforcement process, the reinforcing rod 4 can be inserted through the opening 21, and the baffle 3 can be attached to one side of the shear wall 2. Then, the hook 5 is hooked onto the pre-embedded hanging ring 11. Then, the personnel apply force to rotate the screw 43, which can drive the screw block 51 to move until the reinforcing rod 4 is tensioned on one side of the shear wall 2. Compared with the existing method, when reinforcing the open-type shear wall 2, there is no need to pre-set a corresponding hooking mechanism on the shear wall 2, which indirectly reduces the cost of the reinforcing rib.

[0026] In some technical solutions, threaded cylinders 6 are fixedly installed on both sides of the bottom of the support block 31. A threaded post 62 is screwed into the middle of the threaded cylinder 6 through an internal thread. A limit plate 61 is fixedly installed on the outer end of the threaded post 62. Rubber pads are fixedly installed on the outer side of the limit plate 61 and on one side of the baffle 3. The rubber pads are provided with anti-slip textures. The rubber pads can contact the shear wall to prevent excessive wear defects during the connection reinforcement process.

[0027] In this technical solution, components such as threaded cylinder 6 and threaded column 62 can be used together to place baffle 3 as close as possible to the middle of shear wall 2 when placing baffle 3. Then, the threaded column 62 is rotated to adjust the position of the limiting plates 61 on both sides, so that the limiting plates 61 fit against the side wall of the opening 21 of shear wall 2, which is used to center and limit the baffle 3 to prevent the baffle 3 from shifting, and has the due reinforcement effect.

[0028] Working principle: It should be noted that this utility model is a combined reinforcement structure for precast shear walls with large openings. All components are general standard parts or parts known to those skilled in the art. Its structure and principle can be learned by those skilled in the art through technical manuals or conventional test methods.

[0029] When a combined reinforcement structure is used for a precast shear wall with a large opening, the combined reinforcement structure is placed on one side of the threshold shear wall 2 after initial hoisting. Then, through the combination of the reinforcement mechanism and the shear wall 2, the shear wall 2 can be limited for temporary reinforcement of the shear wall.

[0030] By incorporating a baffle 3, a reinforcing rod 4, and a hook 5, during the reinforcement process, the reinforcing rod 4 can be inserted through the opening 21, and the baffle 3 can be attached to one side of the shear wall 2. The hook 5 is then hooked onto the pre-embedded hanging ring 11. Subsequently, personnel apply force to rotate the screw 43, which moves the screw block 51 until the reinforcing rod 4 is tensioned to one side of the shear wall 2. Compared to existing methods, when reinforcing an open-type shear wall 2, there is no need to pre-install a corresponding hooking mechanism on the shear wall 2, indirectly reducing the cost of the reinforcing ribs. By incorporating a threaded cylinder 6 and a threaded column 62, the baffle 3 is positioned as close as possible to the center of the shear wall 2 during placement. Then, the threaded column 62 is rotated to adjust the position of the limiting plates 61 on both sides, ensuring that the limiting plates 61 are attached to the side wall of the opening 21 of the shear wall 2. This serves to center and limit the baffle 3, preventing it from shifting and achieving the desired reinforcement effect.
