Description

Rebar alignment device for shear wall installation

technical field

The utility model relates to the technical field of construction equipment, in particular to a steel bar calibration device for shear wall installation.

Background technique

In the construction industry, prefabricated shear walls are manufactured in factories, and then transported and hoisted to the floor for installation. Compared with traditional cast-in-place concrete construction, the construction period of the building can be greatly shortened and the construction efficiency of the building can be improved.

At present, in order to ensure the stable connection between the shear wall and the floor, there are two rows of installation holes on the lower end face of the shear wall. Then, concrete is injected into the installation hole for fixing. In the actual construction process, the wall is first hoisted to the top of the steel bar on the floor by a hoisting machine. The worker needs to use an inclined reflector on the floor to observe whether the upper end of the steel bar is aligned with the installation hole. If not, adjust the wall. position, and then the hoisting machine lowers the wall, and the rebar enters the installation hole. However, using the reflector to judge whether the steel bar is aligned with the installation hole, workers need to adjust the inclination angle of the reflector several times to find the position of the installation hole. The calibration and judgment process is cumbersome, resulting in low wall installation efficiency.

Utility model content

The purpose of the utility model is to provide a steel bar calibration device for shear wall installation, which solves the problem of low wall installation efficiency due to complicated calibration process in the prior art.

The plan is basically as follows:

The steel bar calibration device for shear wall installation is characterized in that it includes an upper support plate and a lower support plate, the upper support plate can be fixed on the lower end face of the wall by a fixing piece, and the upper support plate is provided with an upper positioning part corresponding to the position of the installation hole , the lower support plate is provided with a lower positioning part that can be positioned with the steel bar, the upper support plate is fixed with a butt sleeve, the lower support plate is fixed with a butt rod that can cooperate with the butt sleeve, and the distance between the butt rod and the lower positioning part, The same distance as the butt sleeve and the lower locator.

Beneficial effect: The upper positioning part of the upper support plate is positioned with the installation hole in advance, and the upper positioning part can adopt a groove communicating with the installation hole or a protrusion that can enter the installation hole, as long as the upper positioning part can be observed by human eyes It can be aligned with the installation hole, and the lower positioning part of the lower support plate is positioned with the steel bar. The lower positioning part can be a rod or a matching groove in contact with the steel bar, as long as the alignment of the lower positioning part and the steel bar can be observed by the human eye. It is enough; since the distance between the butt rod and the lower positioning part is the same as the distance between the butt sleeve and the lower positioning part, when adjusting the position of the wall, by judging whether the butt sleeve and the butt rod are aligned, it can be determined whether the steel bar is in line with The installation holes are aligned, and compared with the prior art, the calibration efficiency is high.

Further, the upper positioning portion includes a matching groove that can communicate with the mounting hole.

The communication between the matching groove and the mounting hole realizes the positioning of the upper positioning portion and the mounting hole, which is convenient for workers to judge with the naked eye.

Further, the upper end of the matching groove is fixed with an arc-shaped piece that can be matched with the mounting hole.

If the arc-shaped piece does not enter the installation hole, there will be a gap between the upper support plate and the wall, so that the worker can accurately locate the upper support plate and the installation hole.

Further, the lower positioning portion includes a positioning groove that can be matched with the steel bar.

The positioning groove is close to the steel bar to cooperate with the steel bar and realize the positioning of the lower support plate, which is convenient for positioning.

Further, the matching groove and the positioning groove are both semicircular.

The sliding plate is slidably connected with the upper supporting plate, so that the sliding plate will not affect the position of the upper supporting plate during the process of fixing the sliding plate to the wall.

Further, the fixing member further includes end plates fixed on both ends of the sliding plate, wherein one end plate can abut against one side of the wall body, and the other end plate is connected with a moving member that can move toward the other side of the wall body.

The moving piece is close to the side of the wall, so that it can cooperate with the end plate on the other side to clamp the wall to realize the fixation with the wall. The fixing method is simple in structure and strong in operability.

Further, the moving part adopts a bolt that is threadedly connected to the end plate. Rotating the bolt can make the end of the bolt move towards the side of the wall and counteract it, and the operation is simple and convenient.

Further, at least two butt sleeves are arranged on the upper support plate; the number of butt rods on the lower support plate is the same as the number of butt sleeves, and the butt sleeves and the butt rods can be opposite one by one. In this way, the number of calibration devices can be reduced during the calibration process, and only one calibration device can be used to complete the calibration.
