Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction equipment, and in particular to a reusable shear wall corner formwork reinforcement device. Background Technology
[0002] Reusable shear wall corner formwork reinforcement devices are core equipment in building construction. They are primarily used for fixing formwork at shear wall corners. Through the cooperation of internal and external clamps and connecting components, they ensure the formwork remains stable during concrete pouring, preventing displacement and deformation, and guaranteeing the verticality and forming quality of the shear wall corner. The reusability of these devices directly affects construction cost control and resource utilization, and they are widely used in the construction of various shear wall structures, including residential and commercial buildings.
[0003] Currently, various shear wall corner formwork reinforcement technologies exist in the industry. For example, patent application CN223227050 U includes an L-shaped steel plate with tie rods welded to its inner side. A trapezoidal clamp is located at the other end of each tie rod, and a double nut is threaded onto one side of the trapezoidal clamp. The double nuts are threadedly connected to the tie rods and abut against the trapezoidal clamp. This corner formwork reinforcement device welds multiple tie rods to the inner side of the L-shaped steel plate. The tie rods pass through the formwork and are threadedly connected to the trapezoidal clamp and double nuts. By rotating the double nuts, the trapezoidal clamp moves forward and abuts against the inner side of the masonry wall until the double nuts are tightened. This allows the tie rods to fix the L-shaped steel plate against the timber and the timber against the formwork, effectively reinforcing the structural columns at the corners and ends of the masonry wall. This not only improves the efficiency of formwork reinforcement but also enhances construction quality.
[0004] However, this type of device has obvious defects in its reuse: the L-shaped steel plate and the tie rod are fixed by welding. After the concrete is poured, the tie rod will be poured into the concrete and cannot be separated from the L-shaped steel plate. This means that the L-shaped steel plate cannot be recycled and reused separately. It can only be discarded along with the tie rod or left in the structure, which not only wastes steel resources, but also greatly increases construction costs.
[0005] Therefore, it is necessary to provide a reusable formwork reinforcement device for the corner of a shear wall to solve the above-mentioned technical problems. Utility Model Content
[0006] This utility model provides a reusable shear wall corner formwork reinforcement device, which solves the problem that the clamping parts of the existing device are welded and fixed to the connecting screws and cannot be separated after pouring, resulting in the clamping parts being unusable, causing resource waste and increased construction costs. To solve the above-mentioned technical problems, this utility model provides a reusable shear wall corner formwork reinforcement device, comprising: Shear wall formwork; An inner clamping member is disposed on the inner side of the shear wall formwork; An external clamping member is provided on the outer side of the shear wall template; A first nut is disposed on one side of the inner clamping member; The second nut is disposed on one side of the outer clamping member; A connecting component is disposed inside the shear wall template and is used to cooperate with the first nut and the second nut to realize the connection and fixation of the inner clamping component and the outer clamping component.
[0007] Preferably, the inner clamping member includes an abutment member, and a support seat is fixedly installed inside the abutment member.
[0008] Preferably, the outer clamping member includes a corner protector, and a through hole is provided inside the corner protector.
[0009] Preferably, the connecting assembly includes a rod body disposed inside the shear wall template. A first threaded rod is fixedly installed at one end of the rod body, the first threaded rod passing through the support seat. A second threaded rod is fixedly installed at the other end of the rod body, the second threaded rod passing through the through hole.
[0010] Preferably, the first nut is threaded to the outer side of the first threaded rod and abuts against one side of the abutting member, and the second nut is threaded to the outer side of the second threaded rod and abuts against one side of the wrap angle.
[0011] Preferably, limit grooves are provided on both sides of the inner side of the support base, and limit blocks are fixedly installed on both sides of the second threaded rod.
[0012] Preferably, the limiting block is slidably connected to the inner side of the limiting groove.
[0013] Compared with related technologies, the reusable shear wall corner formwork reinforcement device provided by this utility model has the following beneficial effects: This utility model provides a reusable shear wall corner formwork reinforcement device. The device consists of a shear wall formwork, an inner clamping component, an outer clamping component, a first nut, a second nut, and a connecting assembly that work together. During shear wall corner formwork reinforcement, the first threaded rod of the connecting assembly passes through the inner clamping component, and the second threaded rod passes through the outer clamping component. Tightening the first and second nuts secures the formwork without welding. After concrete curing, loosening the nuts allows for separation of the components, eliminating the need to discard the clamping components and connecting assembly. This enables the repeated use of the inner and outer clamping components, reducing steel waste, lowering construction costs, and ensuring the quality of shear wall corner forming.

Detailed Implementation
[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0017] First Embodiment Please refer to the following: Figure 1 , Figure 2 , Figure 3 ,in, Figure 1 A schematic diagram of the first embodiment of a reusable shear wall corner formwork reinforcement device provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the inner clamping component and the outer clamping component; Figure 3 for Figure 2 The diagram shows another perspective of the structure.
[0018] A reusable shear wall corner formwork reinforcement device includes: shear wall formwork 1; Inner clamping member 2, the inner clamping member 2 is disposed on the inner side of the shear wall template 1; External clamping member 5, the external clamping member 5 is disposed on the outer side of the shear wall template 1; The first nut 4 is disposed on one side of the inner clamping member 2; The second nut 6 is disposed on one side of the outer clamping member 5; The connecting component 3 is disposed inside the shear wall template 1 and is used to cooperate with the first nut 4 and the second nut 6 to realize the connection and fixation of the inner clamping member 2 and the outer clamping member 5.
[0019] The inner clamping member 2 includes an abutment member 21, and a support base 22 is fixedly installed inside the abutment member 21.
[0020] The outer clamping member 5 includes a wrapping corner 51, and a through hole 52 is provided inside the wrapping corner 51.
[0021] The connecting component 3 includes a rod 31, which is disposed inside the shear wall template 1. A first threaded rod 32 is fixedly installed at one end of the rod 31, and the first threaded rod 32 passes through the support seat 22. A second threaded rod 33 is fixedly installed at the other end of the rod 31, and the second threaded rod 33 passes through the through hole 22.
[0022] The first nut 4 is threaded to the outer side of the first threaded rod 32 and abuts against one side of the abutting member 21. The second nut 6 is threaded to the outer side of the second threaded rod 33 and abuts against one side of the wrap angle 51.
[0023] By installing the support base 22 on the inner side of the abutment 21, the strength of the contact position between the abutment 21 and the first nut 4 can be increased during use, and deformation of the abutment 21 can be avoided when the connecting assembly 3 pulls on the abutment 21. After installation, two sides of the abutment 21 are fitted with the inner right-angle edge of the shear wall formwork 1; The first threaded rod 32 and the second threaded rod 33 are both fixedly installed at both ends of the rod body 31 by welding.
[0024] The working principle of the reusable shear wall corner formwork reinforcement device provided by this utility model is as follows: Assemble the shear wall formwork 1 at the corner and adjust it to the preset verticality; attach the abutment 21 of the inner clamping member 2 to the inner side of the formwork, and attach the corner 51 (L-shaped structure, adapted to the corner shape) of the outer clamping member 5 to the outer side of the formwork, ensuring that the support base 22 is aligned with the through hole 52; pass the rod 31 of the connecting component 3 through the reserved hole of the shear wall formwork 1, so that the first threaded rod 32 passes through the support base 22 and the second threaded rod 33 passes through the through hole 52; tighten the first nut 4 and the second nut 6 respectively, and through the threaded engagement of the nuts and the threaded rods, push the inner clamping member 2 and the outer clamping member 5 to clamp the shear wall formwork 1 from both sides to complete the reinforcement and ensure that the formwork does not shift or deform during the pouring process; After the concrete is poured and reaches the specified strength, dismantling operations are carried out. First, loosen and remove the first nut 4 and the second nut 6. Finally, remove the inner clamp 2 and the outer clamp 5 respectively. After cleaning and derusting each part, it can be used for the reinforcement of the next shear wall corner formwork, realizing repeated reuse.
[0025] Compared with related technologies, the reusable shear wall corner formwork reinforcement device provided by this utility model has the following beneficial effects: The shear wall formwork 1, inner clamping component 2, outer clamping component 5, first nut 4, second nut 6, and connecting component 3 work together to reinforce the corner formwork of the shear wall. When reinforcing the corner formwork of the shear wall, the first threaded rod 32 of the connecting component 3 passes through the inner clamping component 2, and the second threaded rod 33 passes through the outer clamping component 5. Tightening the first nut 4 and the second nut 6 can clamp and fix the formwork without welding. After the concrete is formed, loosening the nuts can separate the components. There is no need to discard the clamping components and connecting component 3 together, so as to realize the reuse of the inner clamping component 2 and the outer clamping component 5, reduce the waste of steel resources, reduce construction costs, and ensure the forming quality of the shear wall corner.
[0026] Second Embodiment Please refer to the following: Figure 4 Based on the first embodiment of this application which provides a reusable shear wall corner formwork reinforcement device, the second embodiment of this application proposes another reusable shear wall corner formwork reinforcement device. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.
[0027] Specifically, the second embodiment of this application provides a reusable shear wall corner formwork reinforcement device, which differs in that the reusable shear wall corner formwork reinforcement device has limit grooves 7 on both sides of the inner side of the support base 22, and limit blocks 8 are fixedly installed on both sides of the second threaded rod 32.
[0028] The limiting block 8 is slidably connected to the inner side of the limiting groove 7.
[0029] The working principle of the reusable shear wall corner formwork reinforcement device provided by this utility model is as follows: When installing the connecting component 3, align the limiting blocks 8 on both sides of the first threaded rod 32 with the limiting grooves 7 of the support base 22 and insert them along the limiting grooves 7 until the rod 31 is in place; the cooperation between the limiting blocks 8 and the limiting grooves 7 can restrict the rotation of the connecting component 3, thereby making it easier for the user to rotate the first nut 4 on the top of the first threaded rod 32.
[0030] Compared with related technologies, the reusable shear wall corner formwork reinforcement device provided by this utility model has the following beneficial effects: With the setting of the limiting groove 7 and the limiting block 8, when tightening the first nut 4 and the second nut 6, the connecting component 3 will not rotate and shift with the nuts, eliminating the need for multiple people to adjust, thereby simplifying the assembly process of the connecting component 3 and the inner clamping part 2 and improving the template reinforcement efficiency.
[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
