[0028] like Figure 1-2As shown, a reusable assembled column positioning device includes a central connection block 1, four L-shaped transverse length adjustable structures 2, four first clamps 6, four alarms 4 and a polygonal frame 3. The longitudinal ends of the four L-shaped transverse length adjustable structures 2 are respectively connected to the middle of the four frames of the polygonal frame 3 through second clamps 7, and the transverse ends of the four L-shaped transverse length adjustable structures 2 are all connected to the central connection block 1 through threads. The four alarms 4 are respectively installed on the vertical rods 23 of the four L-shaped transverse length adjustable structures 2, and the four first clamps 6 are respectively installed on the connecting rods 211 of the four L-shaped transverse length adjustable structures 2. The polygonal frame 3 includes two L-shaped connecting strips 31, and the two L-shaped connecting strips 31 are connected at both ends by adhesive tape.

[0029] The central connecting block 1 is used to fix and connect four L-shaped transverse length adjustable structures 2; the L-shaped transverse length adjustable structure 2 is used to connect steel bars, and the center position can be adjusted according to actual needs; the first clamp 6 is used to clamp steel bars; the alarm 4 emits a sound through deformation, and its main function is to remind the prefabricated column of the position offset and to reserve a certain buffer space between the assembled column positioning device and the prefabricated column to avoid the direct effect of the prefabricated column on the assembled column positioning device; the polygonal frame 3 is a quadrilateral frame, which is used to withstand the impact of some external forces, strengthen the force of the entire device, and improve stability.

[0030] like Figure 3 As shown, the L-shaped horizontal length adjustable structure 2 includes an adjustable length cross bar 21, a connecting sleeve 22 and a vertical bar 23. One end of the adjustable length cross bar 21 is installed in the mounting hole 11 of the central connecting block 1 through a thread, and the other end of the adjustable length cross bar 21 is installed in the horizontal end of the connecting sleeve 22 through a plug 5. The lower end of the vertical bar 23 is installed in the longitudinal end of the connecting sleeve through a thread, and the upper end of the vertical bar 23 is connected to the L-shaped connecting strip 31 of the quadrilateral frame through a second clamp 7. The first clamp 6 is installed on the connecting rod 211 of the adjustable length cross bar 21, and the alarm 4 is installed on the upper end of the vertical bar 23.

[0031] The adjustable length cross bar 21 can adjust its own length through threads, so that the position of the central connecting block 1 can be adjusted; the connecting sleeve 22 is used to vertically connect the adjustable length cross bar 21 and the vertical bar 23, playing a transfer role; the vertical bar 23 is a hollow structure, which can reduce its own weight. It is used to connect the four-sided square frame and the adjustable length cross bar 21, and plays the role of extending the longitudinal distance and supporting.

[0032] like Figure 3As shown, the adjustable length cross bar 21 includes a connecting rod 211 and an adjusting sleeve 212. A threaded through hole is provided in the adjusting sleeve 212. One end of two adjacent connecting rods 211 is respectively installed at two ends of the adjusting sleeve. The length of the overall adjustable length cross bar 21 is adjusted by the depth of the connecting rod 211 in the threaded through hole; the other end of the connecting rod 211 on the left is installed in the mounting hole 11 of the central connecting block 1 through a thread, the first clamp 6 is installed on the connecting rod 211 on the right, and the other end of the connecting rod 211 on the right is installed in the connecting sleeve through a plug 5.

[0033] The connecting rod 211 and the adjusting sleeve 212 cooperate with each other to adjust the length of the adjustable-length crossbar 21 . The connecting rod 211 is a hollow structure, which can reduce the weight of the connecting rod 211 .

[0034] like Figure 4 As shown, a construction method of an assembled column positioning device comprises the following steps:

[0035] S1, assembling the central connecting block 1, the L-shaped lateral length adjustable structure 2, the first clamp 6, the alarm 4 and the polygonal frame 3 to obtain a reusable assembled column positioning device;

[0036] S11, the L-shaped horizontal length adjustable structure 2 includes an adjustable length cross bar 21, a connecting sleeve 22 and a vertical bar 23, the adjustable length cross bar 21 is connected to the vertical bar 23 through the connecting sleeve, and finally the alarm 4 is hung on the vertical bar 23 and the first clamp 6 is installed on the adjustable length cross bar 21 to obtain a connecting component;

[0037] S12, repeat step S11 to obtain four connecting components in total, and install one end of the four connecting components in the four mounting holes 11 of the central connecting block 1 through threads respectively;

[0038] S13, respectively install the other ends of the four connecting parts on the frames of the two L-shaped connecting strips 31, adjust the length of the adjustable length cross bar 21 according to the size of the prefabricated column, and then pre-fix the two ends of the two L-shaped connecting strips 31 to form an assembled column positioning device.

[0039] S2. Clean the surface of the floor 9 and make it flat. The alignment position of the prefabricated column 8 (the multiple prefabricated steel bars 10 extending from the floor 9 at the location) is obtained by measurement. The assembled column positioning device is clamped with the multiple prefabricated steel bars 10 by the first clamp. The alarm 4 is adjusted to align with the outer side of the prefabricated column 8 by the length of the adjustable length cross bar 21, and then the two L-shaped connecting strips 31 are fixed; if the number of the multiple steel bars is an even number, then the position of the central connecting block 1 is located at the center of the multiple steel bars; if the number of the multiple steel bars is an odd number, then the lengths of the four adjustable length cross bars 21 are adjusted so that the central connecting block 1 is not at the center of the multiple steel bars.

[0040] S3, the prefabricated column 8 is hoisted to about 100 mm above the multiple prefabricated steel bars 10 by a crane, and then the column stops descending. After the workers observe and align the column, the column slowly descends. During the slow descent, if the sleeve of the prefabricated column 8 is not aligned with the multiple prefabricated steel bars 10, the workers will know which direction to push according to the sound prompt issued by the alarm 4, until there is no alarm sound prompt. At this time, the sleeve of the prefabricated column 8 is aligned with the multiple prefabricated steel bars 10, and the ends of the multiple prefabricated steel bars 10 are inserted into the sleeve of the prefabricated column 8 for pre-positioning.

[0041] S4. Remove the assembled column positioning device from the multiple prefabricated steel bars 10, and fully insert the multiple prefabricated steel bars 10 into the sleeve of the prefabricated column 8; remove the L-shaped connecting strip 31, pull out the plug 5, and remove the adjustable length cross bar 21 from the central connecting block 1 to complete the disassembly of the entire device for easy storage of parts.
