[0023] The auxiliary adjustment mechanism 5 includes an electric push rod 501, a U-shaped card plate 502 and a gear movable groove 503. The electric push rod 501 is fixedly installed at the top of the lower V-shaped plate 204 near the driving gear 207. The output end of the electric push rod 501 is fixedly connected to the U-shaped card plate 502. A gear movable groove 503 is opened on one side of the U-shaped card plate 502, and the driving gear 207 is movably inserted into the gear movable groove 503.

[0024] The inner surfaces of the two side clamping claws 209 and the outer surface of the rear clamping plate 212 are fixedly installed with pressure sensors 6. The side clamping claws 209 are movably inserted into the side clamping slots 103, and the rear clamping plate 212 is movably inserted into the rear clamping slot 105. The pressure sensor 6 is electrically connected to the servo motor 211 and the electric push rod 501.

[0025] A universal wheel 7 is movably mounted on the bottom of the support frame 305 , a limit plate 8 is fixedly mounted on the rotating shaft 205 on which the driving gear 207 is mounted, and the bottom end of the guide rod 301 is fitted with the top end of the adjacent double-side plates 102 .

[0026] When the double-column support structure with reserved expansion joints and its auxiliary construction device are used, the first column structure 1 is installed to the specified position, and then the auxiliary lifting structure 2 is moved to the position behind the second column 101 through the lifting line. The lifting line is lowered so that the side claws 209 and the side slots 103 and the rear card plate 212 and the rear slots 105 are in the same horizontal plane position, and the servo motor 211 is controlled to drive the shaft 205 to rotate, and the shaft 205 drives the driving gear 207 to rotate, and the driving gear 207 is driven to rotate. 07 rotates with the driven gear 206 and the transmission gear 208 to rotate in the opposite direction, and the driven gear 206 on the other side is driven to rotate through the driving gear 207, thereby driving the two side claws 209 to rotate inward, so that the side claws 209 are clamped into the side clamping groove 103. At the same time, the rotation of the driving gear 207 will push the rack 214 to move, so that the rack 214 drives the rear clamping plate 212 to move forward and clamp it into the rear clamping groove 105. At this time, the width and length of the column 101 installed each time are different, resulting in three situations: Situation 1: The side clamping claw 209 is first inserted into the side clamping slot 103, and the rear clamping plate 212 has not yet been inserted into the rear clamping slot 105. At this time, the pressure sensor 6 on the surface of the side clamping claw 209 is subjected to pressure and transmits a signal to the servo motor 211 and the electric push rod 501, so that the servo motor 211 stops driving the rotating shaft 205. At the same time, the electric push rod 501 receives the signal and pulls the U-shaped clamping plate 502 downward. At this time, the U-shaped clamping plate 502 drives the inner driving gear 207 to move along the direction of the rotating shaft 205, thereby causing the driving gear 207 to move downward to the position of the limit plate 8, and The movement is stopped by the blocking of the limit plate 8. At this time, the driving gear 207 is no longer meshed with the driven gear 206 and the transmission gear 208, but the driving gear 207 is still meshed with the rack 214. The servo motor 211 is controlled again to drive the rotating shaft 205 to rotate, so that the driving gear 207 only pushes the rack 214 to move, so that the rear clamping plate 212 is clamped into the rear clamping slot 105. When the pressure sensor 6 on the surface of the rear clamping slot 105 is subjected to pressure, the servo motor 211 stops driving the rotating shaft 205, thereby completing the hoisting and clamping of the column structure 1 by the auxiliary hoisting structure 2; Case 2: The rear card plate 212 is first inserted into the rear card slot 105, and the side claw 209 has not yet been inserted into the side card slot 103. In this case, the pressure sensor 6 on the surface of the rear card plate 212 transmits a signal to the servo motor 211 and the electric push rod 501, so that the electric push rod 501 drives the output end to push outward, so that the U-shaped card plate 502 drives the driving gear 207 to move upward along the direction of the rotating shaft 205 until the top of the driving gear 207 contacts the bottom of the upper V-shaped plate 202. At this time, the driving gear 207 is in contact with the bottom of the upper V-shaped plate 202. 07 releases the meshing with the rack 214 and only meshes with the driven gear 206 and the transmission gear 208, and then controls the servo motor 211 to drive the rotating shaft 205 to rotate, so that the driving gear 207 only drives the driven gear 206 and the transmission gear 208 to rotate, so that the side claw 209 is clamped into the side clamping groove 103, and when the pressure sensor 6 on the surface of the side claw 209 is subjected to pressure, the servo motor 211 stops driving the rotating shaft 205, thereby completing the hoisting and clamping of the auxiliary hoisting structure 2 to the column structure 1; Case 3: the side clamping claws 209 and the rear clamping plate 212 are simultaneously clamped into the corresponding side clamping slots 103 and the rear clamping slots 105. At this time, the servo motor 211 is directly stopped to complete the hoisting and clamping of the column structure 1 by the auxiliary hoisting structure 2. Thus, it is possible to clamp and hoist the columns 101 of different sizes; After the auxiliary hoisting structure 2 hoists the column structure 1, the auxiliary positioning structure 3 is moved by the universal wheel 7 to insert the guide rod 301 into the position above the double-side plates 102 on the surface of the first column 101, so that the guide rod 301 fits with the surface of the column 101. At this time, the blocking plate 306 moves in the track groove 302 to fit the blocking plate 306 with the first column 101, thereby positioning the second column 101. The second column structure 1 is lowered by the hoisting line and placed on the surface of the placement plate 303. The bottom end of the column 101 will contact the ball 304. At this time, the second column structure 1 is lowered by the hoisting line and placed on the surface of the placement plate 303. The column structure 1 is pushed toward the first column structure 1 so that its bottom surface contacts the surface of the blocking plate 306, and an expansion gap with the width of the blocking plate 306 is reserved between the two columns 101. Then, the guide rod 301 is directly pulled outward through the universal wheel 7 to move the auxiliary positioning structure 3 out from between the two columns 101. At this time, the second column structure 1 is lowered through the auxiliary lifting structure 2, so that the hook end 402 is aligned with the position of the hook groove 404, and the engaging teeth 106 are staggered, thereby completing the installation of the two columns 101 and reserving the expansion gap between the columns 101.

[0027] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
