Abstract
Description
[Technical Field]
[0001] This utility model relates to the field of building construction, and in particular to a device for preventing the misalignment of pre-embedded reinforcing bars in double-sided composite shear walls. [Background Technology]
[0002] A double-sided composite shear wall is composed of two overlapping concrete wall panels, joined together by a steel truss. Prefabricated in the factory, the panels contain cavities. After on-site installation, concrete is poured into these cavities, creating a wall structure where prefabricated and cast-in-place concrete work together to bear the load. This is commonly known as a "double-skin wall." Vertical connections in double-sided composite shear walls are achieved by inserting reinforcing bars into the cavities before pouring concrete, thus connecting the upper and lower walls into a larger joint surface. Currently, traditional prefabricated double-sided composite shear walls typically use U-shaped reinforcing bars for connection. These connecting bars require pre-embedded reinforcing bars, but there is no reliable fixing method. Vibration during concrete pouring can easily cause the reinforcing bars to shift, resulting in them not being within the cavity area during double-skin wall hoisting. This necessitates repositioning the reinforcing bars, posing a structural safety hazard, and is difficult to correct in areas with significant deviations. [Utility Model Content]
[0003] To overcome the problem that vibration during concrete pouring can easily cause rebar misalignment, resulting in the rebar not being within the cavity during double-layer wall installation and requiring rebar adjustment, this utility model aims to provide a device to prevent misalignment of pre-embedded rebars in double-sided composite shear walls. This utility model is achieved through the following technical solution:
[0004] A device for preventing the pre-embedded reinforcing bars of a double-sided composite shear wall from shifting includes a locking structure that is locked to a fixed object to prevent displacement, and the locking structure is connected to a positioning structure used to position the pre-embedded reinforcing bars in the double-sided composite shear wall during cement vibration.
[0005] As described above, a device for preventing the misalignment of embedded reinforcing bars in a double-sided composite shear wall includes a positioning structure comprising a load-bearing part that bears the oscillation force of cement on the embedded reinforcing bars during cement vibration, and a loading positioning part connected to the load-bearing part for positioning the embedded reinforcing bars and preventing misalignment.
[0006] As described above, in a double-sided composite shear wall pre-embedded reinforcing bar anti-displacement device, the load-bearing part is a bearing plate capable of withstanding the bending stress and torsional stress of the pre-embedded reinforcing bar during cement vibration.
[0007] As described above, in a double-sided composite shear wall pre-embedded reinforcing bar anti-displacement device, the loading and positioning part is a rectangular hole with the same length and width as the pre-embedded reinforcing bar.
[0008] As described above, the pre-embedded reinforcing bar anti-displacement device for double-sided composite shear wall includes a locking structure comprising a first connecting structure locked to a first fixed reinforcing bar and a second connecting structure locked to a second fixed reinforcing bar.
[0009] As described above, a device for preventing the misalignment of pre-embedded reinforcing bars in a double-sided composite shear wall includes a first connecting structure that distributes the oscillation force of cement on the pre-embedded reinforcing bars during cement vibration to a first distributed force-bearing part of a first fixed reinforcing bar. The first distributed force-bearing part is connected to a positioning first fixed reinforcing bar so that the first connecting structure can be accurately installed to the first positioning part of the first fixed reinforcing bar.
[0010] As described above, in a double-sided composite shear wall pre-embedded reinforcing bar anti-deviation device, the first force-dispersing part is a force-dispersing plate, and the first positioning part is a first positioning hole.
[0011] As described above, in a double-sided composite shear wall pre-embedded reinforcing bar anti-deviation device, the second connection structure includes a second distributed force-bearing part that distributes the oscillation force of cement on the pre-embedded reinforcing bar during cement vibration to the second fixed reinforcing bar. The second distributed force-bearing part is connected to a positioning second fixed reinforcing bar so that the second connection structure can be accurately installed to the second positioning part of the second fixed reinforcing bar.
[0012] As described above, in a double-sided composite shear wall pre-embedded reinforcing bar anti-deviation device, the second force-dispersing part is a force-dispersing plate, and the second positioning part is a second positioning hole.
[0013] As described above, in a double-sided composite shear wall pre-embedded reinforcing bar anti-displacement device, the locking structure and the positioning structure are provided with a support member on the coplanar side, which can support the locking structure and the positioning structure and prevent sliding.
[0014] Compared with the prior art, the present invention has the following advantages:
[0015] 1. This device temporarily fixes the pre-embedded reinforcing bars of the precast double-sided composite shear wall during concrete pouring, preventing the pre-embedded reinforcing bars of the double-sided composite shear wall from being misaligned. It effectively supports and fixes the reinforcing bars by using the longitudinal reinforcing bars and stirrups of the wall columns at both ends, while also ensuring that the wall column reinforcing bars do not deviate, reducing the quality risks caused by reinforcing bar misalignment.
[0016] 2. The device can be disassembled and reused after the concrete is poured. Compared with the traditional process of using temporary horizontal steel bars to tie pre-embedded reinforcing bars and wall column steel bars, it can significantly save steel bar costs.
[0017] 3. The device has a simple design and can be manufactured using basic processing methods, thus reducing manufacturing costs. [Attached Image Description]

The support member 6 is a support stirrup.
[0033] The working principle of this embodiment is as follows:
[0034] The process of using a pre-embedded reinforcing bar anti-displacement device for a double-sided composite shear wall, such as... Figure 1 As shown, the supporting stirrups are first temporarily locked to the first and second fixed reinforcing bars at the same height. Then, the first connecting structure is locked to the first fixed reinforcing bar, and the second connecting structure is locked to the second fixed reinforcing bar. The rectangular holes in the positioning structure firmly restrict the embedded reinforcing bars to prevent them from shifting during cement vibration. After the cement is poured, the positioning structure, locking structure, and supporting stirrups are removed. The positioning structure and locking structure can be reused in the next cement pour. This device is used for temporary fixing of embedded reinforcing bars in prefabricated double-sided composite shear walls, ensuring that the embedded reinforcing bars in the double-sided composite shear walls do not shift. It effectively supports and fixes the wall columns using the longitudinal reinforcing bars and stirrups at both ends of the wall columns, while also ensuring that the wall column reinforcing bars do not shift, reducing the quality risks caused by reinforcing bar shifting. Moreover, this device can be disassembled and reused after the concrete is poured. Compared with the traditional process of using temporary horizontal reinforcing bars to tie the embedded reinforcing bars and wall column reinforcing bars, it significantly saves steel bar costs and can be put into on-site construction more efficiently and conveniently.
