Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an auxiliary positioning and installation device for precast columns. Background Technology

[0002] Prefabrication and installation are now widely used in building construction, with prefabricated columns being particularly prevalent. The installation of existing prefabricated columns typically involves using a crane to lift the column and transport it to the vicinity of the predetermined location. The column is then aligned with the pre-embedded steel bars in the ground before being lowered and reinforced, thus completing the installation.

[0003] The process of aligning the precast column with the ground-embedded steel bars requires the cooperation of multiple workers, and the column position needs to be repeatedly lifted and lowered to adjust the position, which is labor-intensive, time-consuming, and inefficient.

[0017] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0018] This application discloses an auxiliary positioning and installation device for precast columns 3. The device includes a frame 1, on which two positioning components are arranged at intervals along the vertical direction. The positioning components include multiple guide units 2, which surround the frame 1. Each guide unit 2 includes a guide rod 23 and a guide wheel 21. The guide rod 23 is slidably connected to the frame 1 along the horizontal direction, and a central shaft 22 is provided at the end of the guide rod 23. The guide wheel 21 is rotatably connected to the central shaft 22. The central shaft 22 is arranged in the horizontal direction. The guide unit 2 also includes a driving component for driving the guide rod 23 to slide. The driving component includes a micro motor 24 and a gear 25. The micro motor 24 is fixedly mounted on the frame 1, and the gear 25 is fixedly connected to the output shaft of the micro motor 24. The rotation axis of the gear 25 is arranged in the vertical direction. A rack is provided on the guide rod 23, and the rack meshes with the gear 25. The micro motor 24 drives the gear 25 to rotate, thereby driving the guide rod 23 to slide.

[0019] It should be noted that there are two gears 25 in the figure, but only one of the gears 25 is connected to the micro motor 24 and is the driving gear 25; the other gear 25 is the driven gear 25, which is set up for the purpose of force balance; at the same time, a laser projector is also provided on the frame 1.

[0020] This tool is mainly used to assist in the hoisting of precast column 3. Specifically, it uses two layers of guide wheels 21 to enable the precast column 3 to be quickly and accurately positioned.

[0021] The frame 1 is mainly made of several rectangular square tubes welded together. The upper two layers of crossbeams each have two round holes in each direction. The guide rod 23 on the guide wheel 21 can slide through these round holes to adjust its position on the frame 1, thereby limiting the precast column 3.

[0022] There are a total of 16 telescopic rods on the upper and lower crossbeams. The upper guide rod 23 is used to coarsely adjust the position of the precast column 3 (by expanding the column size by 50mm), and the second crossbeam is used to finely adjust the column position.

[0023] When using it, first adjust the second layer guide rod 23 so that the laser line at the end of the rod can hit the positioning line of the column (at this time, the guide wheel 21 surrounds the position where the precast column 3 is to be placed). After the second layer is adjusted, the first layer guide rod 23 will automatically adjust according to the extension length of the second layer guide rod 23 (expanding outward by 50mm).

[0024] After the precast column 3 is in place, first install the bottom connector and positioning component. After lifting the device to a height of 1m, install the first fixed diagonal brace. After installation, remove the device (lifted away by the tower crane) and install the second diagonal brace.

[0025] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
