Description

Technical Field

[0001] This utility model relates to the field of shear wall formwork, and more specifically, to a reinforcement structure for shear wall formwork on both sides of an expansion joint. Background Technology

[0002] Utility model patent application CN221823403U discloses a shear wall formwork reinforcement structure, including a building base slab and a formwork set on top of the base slab. A wall is poured on one side of the formwork, and reinforcing ribs are fixedly installed on the side of the formwork away from the wall. This shear wall formwork reinforcement structure solves the problem of vibration during concrete pouring, which makes formwork displacement difficult to detect and adjust promptly. The structure utilizes pre-embedded supports made of scrap steel bars in the building base slab, and then connects the supports to the main joists using turnbuckles and wire ropes. During pouring, the movement of pointers on the turnbuckles is observed to determine if the formwork has shifted.

[0003] In the aforementioned disclosed structure, reinforcement is achieved by casting positioning and connecting steel bars inside the shear wall formwork. However, it lacks a bent and combined reinforcement frame to support the structural strength angle of the reinforcement, and it also lacks a positioning and embedded fixed threaded cylinder to install the reinforcement threaded head. This makes it impossible to combine and position the reinforcement, which is not conducive to adjustment and use, and affects the installation and fixation. Improvements are needed. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a reinforcement structure for shear wall templates on both sides of expansion joints. By embedding positioning plates and fixing threaded cylinders inside the template, combined with internal reinforcement threaded heads, the template can be embedded and positioned, facilitating threaded installation and adjustment, and making hoisting convenient. Furthermore, by welding internal reinforcement frames and bending parts, combined with horizontal and arc-shaped supports, they can be integrated and embedded for overall reinforcement, improving structural strength and stability, and ensuring the safety of fixed installation.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A reinforcement structure for shear wall formwork on both sides of an expansion joint includes a formwork. The surface of the formwork has an inlay groove, and a positioning plate is fixedly inlaid inside the inlay groove. A fixed threaded cylinder is fixedly connected to one side of the positioning plate and is fixedly inlaid inside the formwork. A reinforcement frame is fixedly welded to the outer surface of the fixed threaded cylinder. The surface of the reinforcement frame has a bent portion. Both the reinforcement frame and the bent portion are fixedly inlaid inside the formwork. A horizontal support is fixedly welded to one side of the bent portion, and a connecting rod is fixedly welded to the outer surface of the horizontal support. The connecting rod is fixedly inlaid inside the formwork. An arc-shaped support is fixedly welded to the other side of the bent portion and is fixedly inlaid inside the formwork. Reinforcement threaded heads are threaded onto both ends of the fixed threaded cylinder, and one end of each reinforcement threaded head has an operating hole. The positioning plates are symmetrically distributed on both sides of the formwork surface.

[0007] Furthermore, a U-shaped rod is fixedly connected to one side of the reinforced threaded head, and the U-shaped rod is inserted into one end of the fixed threaded cylinder.

[0008] Furthermore, a limiting ring is slidably sleeved at one end of the U-shaped rod, and the limiting ring is located at one end of the reinforced threaded head.

[0009] Furthermore, a snap-fit ​​notch is provided on one side of the limiting ring, and the snap-fit ​​notch is located at the end of the U-shaped rod. The U-shaped rod is connected by a reinforcing threaded head. Combined with the snap-fit ​​notch on the limiting ring, it can be connected and positioned in combination. When not in use, it can be retracted for positioning. During reinforcement and installation, the direction can be adjusted for lifting. It is efficient, stable, and highly adaptable.

[0010] Furthermore, a support rod is fixedly connected to one side of the arc-shaped bracket, and the support rod is located on one side of the reinforcing frame.

[0011] Furthermore, a longitudinal rod is fixedly connected to one end of the support rod, and the longitudinal rod is fixedly welded to the inside side of the bent portion.

[0012] Furthermore, the reinforcing frames are evenly distributed inside the template and connected to the longitudinal bars by support rods. Multiple reinforcing frames can be combined into an integral structure to ensure the strength and stability of the integrated structure and improve safety in use.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] (1) This solution uses a positioning plate and a fixed threaded cylinder embedded inside the template. Combined with the internal reinforcing threaded head, it can be embedded and positioned, which is conducive to the adjustment of the threaded installation and easy to hoist. Furthermore, by welding the internal reinforcing frame and bending parts, combined with the horizontal support and arc support, it can be connected as a whole and then embedded and reinforced to improve the structural strength and stability and ensure the safety of the fixed installation.

[0015] (2) By reinforcing the threaded head to connect the U-shaped rod, and combining the limit ring to set the snap-fit ​​notch, it can be combined for connection and positioning. When not in use, it can be retracted for positioning. During reinforcement and installation, the direction can be adjusted for lifting. It is efficient, stable and highly adaptable.

[0016] (3) By connecting longitudinal bars with support rods, multiple reinforced frames can be combined into an integral structure to ensure the strength and stability of the integrated structure and improve the safety of use. Attached Figure Description
