[0002] The building expansion joint, that is, the expansion joint, refers to a structural joint provided at an appropriate part in the direction of the construction joint of a building or structure to prevent cracks or damage to the building components caused by climate temperature changes. During the construction and installation of a building, double columns are usually used for support to improve the support strength, and a construction joint needs to be reserved between the double columns in the double-column support structure.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0033] Please refer to Figures 1 to 9 , the present invention provides an embodiment: a double-column support structure with a reserved expansion joint, including two column structures 1, and a plurality of expansion joint filling structures 4 are arranged on one side of the two column structures 1 corresponding to each other;

[0034] The column structure 1 includes a column 101, double side plates 102, side card slots 103, double rear plates 104, rear card slots 105 and clamping teeth 106. Two double side plates 102 are fixedly installed on both sides of the column 101, a side card slot 103 is arranged between the two double side plates 102, two double rear plates 104 are fixedly installed on the opposite sides of the two columns 101, a rear card slot 105 is arranged between the two double rear plates 104, and a plurality of clamping teeth 106 are fixedly installed on the corresponding sides of the two columns 101;

[0035] The expansion joint filling structure 4 includes a filling plate 401, a hook end 402, a fixed end 403, a hook groove 404 and a mounting groove 405.

The two ends of the filling plate 401 are respectively provided with a hook end 402 and a fixed end 403. A plurality of hook grooves 404 are formed at the top end of the column 101. The fixed end 403 is fixedly connected to the inner side of the column 101. The hook end 402 is inserted into the hook groove 404 on the surface of the top end of another column 101. The filling plate 401 is made of silicone rubber. Through the cooperation of the engaging teeth 106 and the filling plate 401, when the two columns 101 are under construction, the two columns 101 are mutually inserted into a structure similar to gear meshing through the engaging teeth 106, so that the expansion joint area between the two columns 101 is increased, thereby improving the stability between the two columns 101. And the two columns 101 are elastically fixed through the filling plate 401. When the column 101 deforms due to thermal expansion or contraction caused by climate temperature changes, the filling plate 401 elastically deforms to pull the columns 101 on both sides, so that the two columns 101 are kept stable. And through the setting of the hook end 402, the engaging teeth 106 of the two columns 101 will not be disengaged from meshing, improving the stability.

An auxiliary lifting structure 2 is provided on the outer side of one column structure 1, and an auxiliary positioning structure 3 is provided on the outer side of the other column structure 1.

[0037] The auxiliary lifting structure 2 includes a U-shaped connecting frame 201, an upper V-shaped plate 202, a lower V-shaped plate 204, a rotating shaft 205, a driven gear 206, a driving gear 207 and a transmission gear 208.

The transmission gear 208 is rotatably connected with one of the rotating shafts 205 in the middle. The driving gear 207 is movably connected with the other rotating shaft 205 in the middle. The width dimension of the driving gear 207 is twice the width dimensions of the driven gear 206 and the transmission gear 208. The driven gear 206 and the transmission gear 208 are meshed and connected with the upper half of the driving gear 207.

[0038] The auxiliary lifting structure 2 further includes a telescopic hole 203, side claws 209, a rear clamping plate 212, a rack positioning plate 213, a rack 214, and a positioning chute 215. A rack positioning plate 213 is fixedly installed near the middle position on the upper part of the lower V-shaped plate 204. A positioning chute 215 is formed at the top end of the rack positioning plate 213. A rack 214 is slidably installed at the top end of the rack positioning plate 213. The rack 214 is slidably engaged into the positioning chute 215. One end of the rack 214 is fixedly installed with a rear clamping plate 212. The width dimension of the driving gear 207 is twice the width dimension of the rack 214. A telescopic hole 203 is formed on the U-shaped connecting frame 201 and near the position of the rack 214. The other end of the rack 214 is slidably inserted into the telescopic hole 203. Side claws 209 are fixedly installed on both of the outermost two rotating shafts 205. The rack 214 is meshed and connected with the lower half part of the driving gear 207.

[0039] Hooks 210 are fixedly installed on both sides of the top end of the upper V-shaped plate 202. Lifting wires are wound around the hooks 210. A servo motor 211 is fixedly installed at the top end of the upper V-shaped plate 202. The output end of the servo motor 211 is connected to the rotating shaft 205 passing through the driving gear 207 through a coupling. When installing the installation column structure 1, first, one of the column structures 1 is installed in place through pre-buried positioning, and then the side claws 209 and the rear clamping plate 212 are respectively clamped into the upper side slot 103 and the rear slot 105 of the other column structure 1 to realize the clamping of the auxiliary lifting structure 2 on the other column structure 1. Subsequently, the column 101 is lifted by the lifting wire, and the column 101 is moved near the column 101 that has been installed.

[0040] The auxiliary positioning structure 3 includes a guide rail rod 301, a track groove 302, a placement plate 303, balls 304, a support frame 305, and a blocking plate 306. A track groove 302 is formed at the top end of the guide rail rod 301. A blocking plate 306 is slidably installed in the track groove 302. A placement plate 303 is fixedly installed on one side of the guide rail rod 301. A plurality of balls 304 are arranged at the top end of the placement plate 303. A plurality of support frames 305 are fixedly installed at the bottom ends of the guide rail rod 301 and the placement plate 303. When moving the column 101 through the auxiliary lifting structure 2, the column 101 is placed on the placement plate 303 to position between the two columns 101, and the column 101 is moved through the balls 304 to make the two column structures 1 close to each other. The column 101 is blocked by the blocking plate 306 to leave a telescopic joint between the two columns 101, so as to realize the auxiliary construction of the column 101.

[0041] The auxiliary adjustment mechanism 5 includes an electric push rod 501, a U-shaped clamping plate 502 and a gear moving slot 503. An electric push rod 501 is fixedly installed at the top of the lower V-shaped plate 204 near the position of the driving gear 207. The output end of the electric push rod 501 is fixedly connected with a U-shaped clamping plate 502. A gear moving slot 503 is formed on one side of the U-shaped clamping plate 502, and the driving gear 207 is movably clamped into the gear moving slot 503.

[0042] Pressure sensors 6 are fixedly installed on the inner surfaces of two of the side claws 209 and the outer surface of the rear clamping plate 212. The side claws 209 are movably clamped into the side clamping slots 103, and the rear clamping plate 212 is movably clamped into the rear clamping slot 105. The pressure sensors 6 are electrically connected to the servo motor 211 and the electric push rod 501.

[0043] Universal wheels 7 are movably installed at the bottom of the support frame 305. A limiting plate 8 is fixedly installed on the rotating shaft 205 on which the driving gear 207 is installed. The bottom end of the guide rail rod 301 is attached to the top end of the adjacent double side plates 102.

[0044] When the double-column support structure with a reserved expansion joint and its auxiliary construction device are in use, the first column structure 1 is installed at the designated position. Subsequently, the auxiliary hoisting structure 2 is moved to the position behind the second column 101 through the hoisting wire. The hoisting wire descends so that the side claws 209 and the side clamping slots 103 and the rear clamping plate 212 and the rear clamping slots 105 are in the same horizontal plane position. The servo motor 211 is controlled to drive the rotating shaft 205 to rotate. The rotating shaft 205 drives the driving gear 207 to rotate. The rotation of the driving gear 207 drives the driven gears 206 and the transmission gear 208 to rotate in the opposite direction. The driving gear 207 drives the driven gear 206 on the other side to rotate, thereby driving the two side claws 209 to rotate inwards so that the side claws 209 are clamped into the side clamping slots 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 be clamped into the rear clamping slot 105. At this time, there are three situations due to the different width and length dimensions of each installed column 101:

[0045] Case 1: The side claw 209 is first inserted into the side slot 103, and the rear clamping plate 212 has not been inserted into the rear slot 105 yet. At this time, the pressure sensor 6 on the surface of the side claw 209 is pressured and transmits signals to the servo motor 211 and the electric push rod 501, causing the servo motor 211 to stop 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 to move downward. At this time, the U-shaped clamping plate 502 drives the inner active gear 207 to move along the direction of the rotating shaft 205, and then the active gear 207 moves downward to the position of the limit plate 8 and stops moving due to the block of the limit plate 8. At this time, the active gear 207 is no longer meshed with the driven gear 206 and the transmission gear 208, but the active gear 207 is still meshed with the rack 214. Then, control the servo motor 211 to drive the rotating shaft 205 to rotate, so that the active gear 207 only pushes the rack 214 to move, so that the rear clamping plate 212 is inserted into the rear slot 105. When the pressure sensor 6 on the surface of the rear slot 105 is pressured, the servo motor 211 stops driving the rotating shaft 205, thus completing the hoisting and clamping of the auxiliary hoisting structure 2 to the column structure 1;

[0046] Case 2: The rear clamping plate 212 is first inserted into the rear slot 105, and the side claw 209 has not been inserted into the side slot 103 yet. At this time, similarly to Case 1, the pressure sensor 6 on the surface of the rear clamping plate 212 transmits signals to the servo motor 211 and the electric push rod 501, causing the electric push rod 501 to drive the output end to push outwards, so that the U-shaped clamping plate 502 drives the active gear 207 to move upward along the direction of the rotating shaft 205 until the top of the active gear 207 contacts the bottom end of the upper V-shaped plate 202. At this time, the active gear 207 disengages from the rack 214 and is only meshed with the driven gear 206 and the transmission gear 208. Subsequently, control the servo motor 211 to drive the rotating shaft 205 to rotate, so that the active gear 207 only drives the driven gear 206 and the transmission gear 208 to rotate, so that the side claw 209 is inserted into the side slot 103. When the pressure sensor 6 on the surface of the side claw 209 is pressured, the servo motor 211 stops driving the rotating shaft 205, thus completing the hoisting and clamping of the auxiliary hoisting structure 2 to the column structure 1;

[0047] Case 3: The side claw 209 and the rear clamping plate 212 are simultaneously inserted into the corresponding side slot 103 and rear slot 105. At this time, directly stop the servo motor 211 to complete the hoisting and clamping of the auxiliary hoisting structure 2 to the column structure 1;

[0048] Thus, the clamping and hoisting of columns 101 with different sizes are realized;

[0049] After the auxiliary lifting structure 2 hoists the column structure 1, the auxiliary positioning structure 3 is moved through the universal wheels 7, so that the guide rail rod 301 is inserted above the double-sided plates 102 on the surface of the first column 101, and the guide rail rod 301 is fitted to the surface of the column 101. At this time, the blocking plate 306 moves in the track groove 302, so that the blocking plate 306 is fitted to the first column 101, thereby positioning the second column 101. The second column structure 1 is lowered through the lifting wire and placed on the surface of the placing plate 303. The bottom end of the column 101 will contact the ball 304. At this time, the second column structure 1 is pushed toward the first column structure 1, so that the bottom surface thereof contacts the surface of the blocking plate 306. A telescopic joint with the width of the blocking plate 306 is reserved between the two columns 101. Subsequently, the guide rail rod 301 is directly pulled outwards through the universal wheels 7, so that the auxiliary positioning structure 3 is removed 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 telescopic joint between the columns 101.

[0050] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced by the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.
