Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and specifically, to a prefabricated truss-type shear wall reinforcement device. Background Art

[0002] The prefabricated truss-type shear wall is a structural reinforcement system, usually used to improve the stability and resistance of buildings in natural disasters such as earthquakes. This shear wall system adopts a truss structure and is composed of prefabricated truss elements, which can be quickly assembled and installed on site. During the installation process of the shear wall, fixing devices are usually required to temporarily fix both ends of the shear wall.

[0003] During the use of the current reinforcement devices, the process is still relatively cumbersome. Users need to take out, install, fix, and adjust, and the procedures are relatively complex, unable to fix the shear wall quickly, reducing work efficiency and the flexibility of the device.

[0004] Therefore, it is necessary to provide a prefabricated truss-type shear wall reinforcement device to solve the above problems. Summary of the Utility Model

[0005] The utility model provides a prefabricated truss-type shear wall reinforcement device. In this solution, a pair of clamping plates are used to clamp the shear wall, thereby realizing the support and fixation of the shear wall. It has strong applicability, simple and fast operation, without complex procedures, and can effectively improve work efficiency.

[0006] Therefore, the adopted technical solution is as follows:

[0007] A prefabricated truss-type shear wall reinforcement device includes a base. Universal wheels are installed at the bottom of the base, and a pair of symmetrically arranged limiting components are provided above the base. The limiting components include a first limiting rod and a second limiting rod. The first limiting rod and the second limiting rod are arranged in parallel and their bottom ends are rotatably connected to the base. Above the base, there are a pair of oppositely arranged clamping plates. Connecting blocks are fixed on the opposite sides of the pair of clamping plates. The top ends of the first limiting rod and the second limiting rod are rotatably connected to the connecting blocks.

[0008] Rotating blocks are rotatably connected to the first limiting rod and the second limiting rod. A vertically arranged first hydraulic rod is fixed on the base. The top end of the first hydraulic rod is fixedly connected to a horizontally arranged lifting rod. The two ends of the lifting rod respectively pass through the rotating blocks on the first limiting rod and the second limiting rod and are slidably connected to the rotating blocks.

[0009] A further technical solution lies in that: the clamping plates and the connecting blocks are perpendicular to each other, and anti-slip patterns are engraved on the adjacent sides of the two clamping plates.

[0010] A further technical solution lies in that: a handle is fixed on the base.

[0011] A further technical solution lies in that: a docking groove is formed on the base, and the clamping plate is located above the docking groove.

[0012] A further technical solution lies in that: a pair of symmetrically arranged support blocks are slidably connected to the bottom of the base, and the pair of support blocks are distributed at both ends of the base.

[0013] A further technical solution lies in that: a pair of second hydraulic rods are fixedly connected to the upper part of the base corresponding to the support blocks, and the output ends of the pair of second hydraulic rods are respectively fixedly connected to the pair of support blocks.

[0014] A further technical solution lies in that: a plurality of balls are installed inside the rotating block, and the balls are abutted against the outer surface of the lifting rod.

[0015] The working principle and beneficial effects of this application are as follows:

[0016] In this solution, a shear wall is clamped by a pair of clamping plates, so as to realize the support and fixation of the shear wall. The distance between the pair of clamping plates can be flexibly adjusted, so that this device can be applicable to shear walls of various thicknesses, with strong applicability. Moreover, the movement of the pair of clamping plates can be realized by the lifting of the first hydraulic rod, and the operation is simple and fast, without complex processes, which can effectively improve work efficiency. Under the action of the limiting component, the pair of clamping plates can always remain vertical during the movement, so as to force the surfaces of the pair of clamping plates to be completely attached to the surface of the shear wall. By increasing the contact area between the device and the shear wall, the fixing effect of the device on the shear wall is improved. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manner

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] As Figures 1-4 shown, an assembled truss-type shear wall reinforcement device includes a base 1. A plurality of universal wheels 9 are installed at the bottom end of the base 1, and a pair of symmetrically arranged limiting components 4 are provided on the upper side of the base 1. The limiting component 4 includes a first limiting rod 401 and a second limiting rod 402. The bottom ends of the first limiting rod 401 and the second limiting rod 402 are rotatably connected to the base 1, and the first limiting rod 401 and the second limiting rod 402 are arranged in parallel. A pair of symmetrically arranged clamping plates 2 are provided on the upper side of the base 1. Connecting blocks 3 are fixedly connected to the mutually remote ends of the pair of clamping plates 2. The top ends of the first limiting rod 401 and the second limiting rod 402 are rotatably connected to the connecting blocks 3. Rotating blocks 7 are rotatably connected to one ends of the first limiting rod 401 and the second limiting rod 402. A first hydraulic rod 5 is installed at the top end of the base 1. The output end of the first hydraulic rod 5 is fixedly connected to a lifting rod 6. The two ends of the lifting rod 6 respectively penetrate through a plurality of rotating blocks 7 and are slidably connected to the rotating blocks 7.

[0025] The assembled truss-type shear wall is a structural reinforcement system, usually used to improve the stability and resistance of buildings in natural disasters such as earthquakes. This shear wall system adopts a truss structure and is composed of prefabricated truss elements, which can be quickly assembled and installed on site. During the installation process of the shear wall, fixing devices are usually required to temporarily fix the two ends of the shear wall.

[0026] In this solution, the user can quickly move the base 1 through multiple universal wheels 9 at the bottom of the base 1. Move the base 1 to one side of the shear wall, so that a pair of clamping plates 2 stand at both ends of the shear wall respectively. Then start the first hydraulic rod 5 to move downward, and then drive the lifting rod 6 to move through the first hydraulic rod 5. During the descent of the lifting rod 6, it will slide within multiple rotating blocks 7 and drive the rotating blocks 7 to rotate on the first limiting rod 401 and the second limiting rod 402, thereby forcing a pair of first limiting rods 401 and second limiting rods 402 to tilt in the direction of approaching each other, and then drive a pair of clamping plates 2 to move synchronously in the direction of approaching each other. When one end of one of the clamping plates 2 first abuts against the surface of the shear wall, it will push the base 1 in the direction of the clamping plate 2 under the action of the reaction force until the other clamping plate 2 also abuts against the shear wall, and then the base 1 stops moving. Then, the mutually approaching ends of a pair of clamping plates 2 clamp the shear wall. At this time, the user shuts down the first hydraulic rod 5 to stop the movement of the lifting rod 6. Thus, a pair of clamping plates 2 cooperate with a pair of limiting components 4 to form a stable support for both ends of the shear wall, completing the fixation of the shear wall.

[0027] In this solution, the distance between a pair of clamping plates 2 can be flexibly adjusted, so that this device can be applicable to shear walls of various thicknesses, with strong applicability. The movement of a pair of clamping plates 2 can be achieved by the lifting of the first hydraulic rod 5, and the operation is simple and fast, without complex processes.

[0028] The first limiting rod 401 and the second limiting rod 402 on the same side always remain parallel during the rotation process. With this setting, it can be ensured that the tops of the first limiting rod 401 and the second limiting rod 402 are always at the same horizontal position, and then ensure that the connecting block 3 always remains horizontal during the movement, while the clamping plate 2 always remains vertical, thereby forcing the surfaces of the mutually approaching ends of a pair of clamping plates 2 to completely fit the surface of the shear wall. By increasing the contact area between the device and the shear wall, the fixation effect of the device on the shear wall is improved.

[0029] The clamping plate 2 and the connecting block 3 are perpendicularly arranged to each other, and anti-slip patterns are engraved on the mutually approaching ends of a pair of clamping plates 2.

[0030] The anti-slip patterns engraved on the clamping plate 2 can effectively enhance the friction between the clamping plate 2 and the shear wall, thereby further improving the support effect of the device on the shear wall.

[0031] A handle 8 is fixedly connected to the top end of the base 1.

[0032] Through the setting of the handle 8, it is convenient for the user to push the whole device, realize the rapid movement of the whole device, and improve the flexibility of the device.

[0033] A docking groove 12 is provided at the central position of one end of the base 1 close to the clamping plate 2, and the clamping plate 2 is arranged above the docking groove 12.

[0034] When the user fixes the shear wall through this device, the shear wall can be located inside the docking groove 12, so as to ensure that a pair of clamping plates 2 can completely extend to both sides of the shear wall. If the docking groove 12 is not provided, for a pair of clamping plates 2 to completely extend to both sides of the shear wall, the position of the clamping plates 2 needs to extend outside the base 1. In this way, it may cause the overall center of gravity of the device to be unstable and reduce the stability of the device.

[0035] A pair of symmetrically arranged support blocks 10 are slidably connected to the bottom end of the base 1. The pair of support blocks 10 are distributed on both sides of the bottom end of the base 1. A pair of second hydraulic rods 11 are installed at the top end of the base 1, and the output ends of the pair of second hydraulic rods 11 are respectively fixedly connected to the pair of support blocks 10.

[0036] After a pair of clamping plates 2 support the shear wall, the user needs to start the pair of second hydraulic rods 11 to push downward, thereby driving the pair of support blocks 10 to move downward synchronously. After the bottom ends of the pair of support blocks 10 are in contact with the ground, they can support the base 1 together with a plurality of universal wheels 9. And the lower surface of the support block 10 is set to be serrated, which can enhance the friction between the support block 10 and the ground, so that the base 1 is difficult to move under the support of the pair of support blocks 10, and it can effectively prevent the device from moving itself when supporting and fixing the shear wall, thereby improving the fixing effect of the device on the shear wall.

[0037] A plurality of balls are installed inside the rotating block 7, and the balls are in contact with the outer surface of the lifting rod 6.

[0038] The setting of the balls inside the rotating block 7 can effectively improve the smoothness of the lifting rod 6 sliding inside the rotating block 7 and reduce the possibility of the lifting rod 6 getting stuck during the lifting process.

[0039] Working principle:

[0040] When in use, the user pushes the handle 8 so that the base 1 can move quickly through the multiple universal wheels 9 at the bottom thereof. The user moves the base 1 to one side of the shear wall and makes the shear wall located on the inner side of the docking groove 12, thereby ensuring that the pair of clamping plates 2 can be fully extended to both sides of the shear wall. Then the first hydraulic rod 5 is started to move downward, and the lifting rod 6 is driven to move by the first hydraulic rod 5. During the descending process, the lifting rod 6 will slide in the multiple rotating blocks 7 and drive the rotating blocks 7 to rotate on the first limiting rod 401 and the second limiting rod 402, thereby forcing the pair of first limiting rods 401 and the second limiting rod 402 to tilt in the direction of approaching each other, thereby driving the pair of clamping plates 2 to move synchronously in the direction of approaching each other. When one end of one of the clamping plates 2 first abuts against the surface of the shear wall, the base 1 will be pushed to move in the direction of the clamping plate 2 under the action of the reaction force until the other clamping plate 2 also abuts against the shear wall, and the base 1 stops moving, thereby the pair of clamping plates 2 approaching each other. The first and second limit rods 401 and 402 on the same side are always kept parallel during the rotation process, thereby ensuring that the connecting block 3 always remains horizontal during the movement, and the clamping plate 2 always remains vertical, thereby forcing the surface of the pair of clamping plates 2 close to each other at one end to be completely fitted with the surface of the shear wall. After the pair of clamping plates 2 achieves the support of the shear wall, the user starts the pair of second hydraulic rods 11 to push downward, thereby driving the pair of support blocks 10 to move synchronously downward. After the bottom ends of the pair of support blocks 10 are in contact with the ground, they can support the base 1 together with the multiple universal wheels 9, making it difficult for the base 1 to move under the support of the pair of support blocks 10, thereby preventing the device from moving itself when supporting and fixing the shear wall.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
