Description

Technical Field

[0001] The present invention relates to the technical field of engineering construction, and in particular to a laser hoisting positioning frame and an assembled wall installation method. Background Art

[0002] Prefabricated buildings are structures assembled on-site from prefabricated components. Based on the form of prefabricated components and the construction method, they are categorized into five types: block buildings, panel buildings, cassette buildings, skeleton panel buildings, and slab-and-rise buildings. During prefabricated building construction, a lifting device is used to lift the wall onto pre-embedded rebar. The angle of the wall is then adjusted to align the pre-set holes with the rebar. The wall is then lowered to ensure the rebar fits neatly into the pre-set holes.

[0003] When the walls of prefabricated buildings are matched, because the embedded steel bars and the wall are higher, when the wall is hoisted above the embedded steel bars and the reserved holes on the wall are aligned with the steel bars, it is difficult for the staff below or the hoisting operator to observe the alignment of the steel bars and the reserved holes. Therefore, the alignment operation is very troublesome, which greatly reduces the efficiency of positioning and alignment. In the process of hoisting the wall to pass through the steel bars, because the steel bars are thin and tall, with the lower end being the fixed end and the upper end being the free end, the upper end of the steel bars is prone to deflection and bending, that is, the central axis of the steel bars cannot remain vertical, which will affect The steel bars and the reserved holes need to be aligned and positioned or the wall needs to be sunk, and then the assembly walls in the upper and lower directions need to be adjusted so that the two side surfaces of the assembly walls in the upper and lower directions are flush. Therefore, when the above-mentioned prefabricated walls are actually assembled, the actual operation efficiency is low and the assembly accuracy is poor. Moreover, since the steel bars and the reserved holes contain multiple groups, the steel bars and the reserved holes need to be aligned and plugged in at the same time, which requires close cooperation between the operators and the hoisting personnel, resulting in low assembly efficiency. In addition, the assembly wall in the upper position is prone to deflection, which in turn causes the steel bars in the lower position to break. Summary of the Invention

[0043] In order to make the objects and advantages of the present application more clear, the present application is specifically described below in conjunction with embodiments. It should be understood that the following description is only used to describe one or several specific embodiments of the present application, and does not strictly limit the scope of protection of the present application. As used herein, the terms "parallel" and "perpendicular" are not limited to their strict geometric definitions, but include reasonable and inconsistent tolerances for machining or human error;

[0044] The accompanying drawings are referred to in the description of the present application. Figures 1 to 13 The laser hoisting positioning frame of the present application is described in detail as follows:

[0045] In actual hoisting and installation of the assembled wall, for the hoisting and installation of a building with a low floor, the assembled wall can be hoisted by a vehicle-mounted hoisting arm. For the hoisting and installation of a high-rise building with a high floor, a fixed hoisting device needs to be constructed to realize the installation of the assembled wall. In actual installation, in order to ensure that the assembled wall at the upper position can be accurately placed on the upper position of the assembled wall at the lower position and ensure that the reinforcement of the assembled wall at the lower position can be accurately inserted into the reserved hole of the assembled wall at the upper position, the workers need to assist the hoisting personnel to make position fine adjustment, so that the reinforcement of the assembled wall at the lower position can be aligned with the reserved hole of the assembled wall at the upper position. The above fine adjustment process is relatively slow, and the accuracy of the hoisting device is poor, which needs to be repeatedly guided to ensure that the reinforcement is aligned with the reserved hole, thereby resulting in a very low construction efficiency.

[0046] To this end, the present application provides a laser hoisting positioning frame, which comprises:

[0047] The plug-in frame body 100 is arranged at the lower position of the hoisting device.

[0048] The plug-in pipe 110 is arranged in multiple groups along the length direction of the plug-in frame body 100, and is used to implement the combination of the upper end reinforcement of the wall. The adjusting frame 200 is arranged at the upper position of the plug-in frame body 100, and is used to implement the adjustment of the levelness of the plug-in frame body 100.

[0049] The driving unit is used to drive the plug-in pipe 110 to be plugged and fixed with the upper end reinforcement of the wall or to be separated from the upper end reinforcement of the wall.

[0050] The laser detection head 300 is installed on the plug-in frame body 100 and is used to measure the coordinate information of the wall. The laser detection head 300 transmits the detected coordinate signal to the central control unit, and the central control unit is used to control the adjusting frame 200 to adjust the levelness of the plug-in frame body 100.

[0051] In an embodiment, the laser probe head 300 can be installed in multiple groups on the plug-in frame body 100. Through the multiple laser probe heads 300, the position signal of the upper end of the wall can be more accurately obtained, and the coordinate signal of the upper end of the wall steel bar can be obtained. By adjusting the position of the plug-in pipe 110, it can be ensured that the position of the plug-in pipe 110 corresponds to the position of the upper end of the wall steel bar, so as to ensure that the upper end of the wall steel bar is accurately inserted into the plug-in pipe 110, thereby ensuring that the plug-in frame body 100 can effectively implement the grabbing of the wall, and ensuring that the wall is accurately hoisted above the wall that has been installed.

[0052] In an embodiment, when the plug-in pipe 110 fixes the upper steel bar of the wall, the wall will be inclined to a certain extent, and the levelness of the upper end of the wall cannot be guaranteed. Therefore, the central control unit can effectively adjust the levelness of the plug-in frame body 100 to ensure that the upper and lower positions of the wall are aligned, thereby ensuring the accuracy of the installation position.

[0054] In an embodiment, the positioning frame 400 is in the shape of a rectangular frame. The positioning frame 400 abuts against both sides of the upper end of the wall, and the plug-in pipe 110 extends out of the frame surface of the positioning frame 400, so that the steel bar at the upper end of the wall extends into the plug-in pipe 110, thereby ensuring that the steel bar can be effectively fixed to the plug-in pipe 110.

[0056] In an embodiment, when clamping the steel bar, the driving unit is started to make the plug-in pipe 110 move vertically and make the driving slope 111 abut against the driven slope 121, so as to drive the two sets of clamping arc blocks 120 to move close to each other, thereby clamping the steel bar and implementing the engagement of the wall.
