Description
Technical Field
[0001] The utility model relates to the technical field of precast column positioning, in particular to a precast column installation and positioning device. Background Art
[0002] An assembled building is a building assembled on site from precast components. According to the form of precast components and construction methods, it is divided into five types: block building, panel building, box building, skeleton panel building, and lifting slab and storey building, etc., including precast columns, precast beams, precast wall panels, and precast stair slabs, etc. Compared with traditional construction technologies, precast assembled buildings themselves have the characteristics of fast construction speed, short construction period, high production efficiency, good product quality, and low production cost.
[0003] Currently, in the existing technology, when a precast column is hoisted and installed, since the precast column is formed by pouring concrete, the volume and weight of the column body are relatively large, and the precast column will have a slight swing due to external factors during hoisting. The precast column under swing is prone to tilt of the precast column body, resulting in insufficient perpendicularity of the installed precast column. Most of the supporting devices are installed at one end on the side of the precast column and at the other end on the upper end of the base plate. Once fixed firmly, subsequent adjustment cannot be carried out, and secondary adjustment cannot be performed on the original basis, resulting in insufficient installation accuracy of the precast column and affecting the building quality.
[0004] Therefore, the utility model provides a precast column installation and positioning device. Summary of the Utility Model
[0005] Therefore, the technical problem to be solved by the utility model is to overcome the problems in the prior art that when a precast column is hoisted and installed, the precast column itself is relatively heavy, and the precast column will shake due to external force factors during hoisting, making it difficult to dock and install the precast column. When the precast column is being docked, it is not easy to perform secondary adjustment on it, which will cause the threaded locking holes of the precast column to be difficult to dock, and will also result in insufficient installation accuracy of the precast column, affecting the building quality.
[0006] To solve the above technical problems, the utility model provides a precast column installation and positioning device.
[0007] In an embodiment of the utility model, it includes a suspension rod and a precast column movably sleeved on the inner side wall surface of the suspension rod, a lap plate movably sleeved on the outer edge position at the bottom of the precast column, a motor fixedly installed on the top surface of the lap plate, a slider threadedly and movably sleeved on the outer surface of the output end of the motor, a support rod fixedly installed on the outer surface of the slider, a swing push arm two swingably sleeved on the top surface of the slider, the other end of the swing push arm two is movably sleeved with a fitting limit plate, and one end of the support rod is movably sleeved on the outer surface of the fitting limit plate;
[0008] The bottom surface of the suspension rod is fixedly connected with a steel wire suspension rope, and the outer surface of the steel wire suspension rope is fixedly connected with a C-shaped docking sleeve.
[0009] In an embodiment of the present utility model, swing locks are arranged on both side surfaces of the C-shaped docking sleeve.
[0010] In an embodiment of the present utility model, an angle block is fixedly connected to the corner position of the C-shaped docking sleeve and is arranged at one end of the steel wire suspension rope.
[0011] In an embodiment of the present utility model, a docking rod is arranged on one side surface of the C-shaped docking sleeve.
[0012] In an embodiment of the present utility model, a docking groove is formed on the outer surface of the C-shaped docking sleeve and at the edge position on one side of the docking rod.
[0013] In an embodiment of the present utility model, a motor is arranged on the inner surface of the C-shaped docking sleeve, and a swing push arm I is fixedly connected to the output end of the motor.
[0014] In an embodiment of the present utility model, a fitting plate is swingably connected to one end of the swing push arm I, and a hollow anti-slip strip is fixedly connected to the outer surface of the fitting plate.
[0015] In an embodiment of the present utility model, a limiting track is fixedly connected to the top surface of the overlapping plate, and the bottom surface of the slider is movably sleeved on the top surface of the limiting track.
[0016] The above technical solution of the present utility model has the following advantages compared with the prior art:
[0017] For a precast column installation and positioning device of the present utility model, it is sleeved on the outer surface of the precast column in cooperation with the C-shaped docking sleeve, and then sleeved on the surface of the suspension rod by a crane to lift the precast column. At the same time, the steel wire suspension rope on the outer surface of the suspension rod is used to pull the C-shaped docking sleeve. Because the installation position of the C-shaped docking sleeve is biased towards the top edge position of the precast column, the center of gravity of the precast column is always located at the bottom of the C-shaped docking sleeve, achieving the effect that the lower the center of gravity of an object, the more stable its reaction to external forces, and it is not easy to topple or shake. Under the action of the self-gravity of the precast column, the precast column is always in a vertical state.
[0018] A precast column installation and positioning device according to the present utility model. When hoisting a precast column, the overlapping plate is moved to the position where the precast column needs to be installed. With the rotation of the motor, the slider on the surface of the output end of the motor moves towards the direction of fitting the limiting plate. Then, the supporting rod and the swinging push arm II on the outer surface of the slider push the fitting limiting plate. At the same time, it cooperates with the inner wall surface of the fitting limiting plate to contact the bottom surface of the precast column. Then, the shape of the fitting limiting plate is used to control the swinging angle and swinging amplitude of the precast column, avoiding the swinging amplitude of the precast column from expanding due to inertia. As the two fitting limiting plates continuously close and approach each other, the swinging precast column is gradually stabilized, so that the precast column can be vertically lowered to the appropriate position under the action of the crane, and then the precast column is fixed at a specific position by the staff. It achieves the effect of adjusting and limiting the position of the precast column by using the fitting limiting plate, so that the precast column can be lowered at a vertical angle.

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.
[0028] Reference Figures 1 to 5 As shown, a prefabricated column installation and positioning device of the utility model comprises a suspension rod 11 and a prefabricated column 12 movably sleeved on the inner wall surface of the suspension rod 11, a lap plate 13 movably sleeved on the outer edge position of the bottom of the prefabricated column 12, a motor 132 is fixedly installed on the top surface of the lap plate 13, a slider 133 is movably sleeved on the outer surface of the output end of the motor 132, a support rod 135 is fixedly installed on the outer surface of the slider 133, a swing push arm 134 is swingably sleeved on the top surface of the slider 133, a fitting limit plate 136 is movably sleeved on the other end of the swing push arm 134, and one end of the support rod 135 is movably sleeved on the outer surface of the fitting limit plate 136;
[0029] A steel wire rope 111 is fixedly connected to the bottom surface of the suspension rod 11 , and a C-shaped docking sleeve 112 is fixedly connected to the outer surface of the steel wire rope 111 .
[0030] During operation, the C-type docking sleeve 112 is sleeved on the outer surface of the prefabricated column 12, and then sleeved on the surface of the suspension rod 11 through the crane to lift the prefabricated column 12, and at the same time, the steel wire rope 111 on the outer surface of the suspension rod 11 is used to pull the C-type docking sleeve 112. Because the installation position of the C-type docking sleeve 112 is biased towards the top edge of the prefabricated column 12, the center of gravity of the prefabricated column 12 is always located at the bottom of the C-type docking sleeve 112, achieving the effect that the lower the center of gravity of the object, the more stable its reaction to external force is, and it is not easy to tip over or shake. Under the action of the self-gravity of the prefabricated column 12, the prefabricated column 12 is always in a vertical state;
[0031] When hoisting the precast column 12, move the lapping plate 13 to the position where the precast column 12 needs to be installed. Cooperate with the rotation of the motor 132, so that the slider 133 on the surface of the output end of the motor 132 moves in the direction of fitting the limiting plate 136. Then, through the support rod 135 and the swing push arm two 134 on the outer surface of the slider 133, push the fitting limiting plate 136. At the same time, cooperate with the inner wall surface of the fitting limiting plate 136 to contact the bottom surface of the precast column 12. Then, use the shape of the fitting limiting plate 136 to control the swing angle and swing amplitude of the precast column 12, so as to avoid the swing amplitude of the precast column 12 from expanding due to inertia. As the two fitting limiting plates 136 continuously close and approach each other, the precast column 12 swinging left and right gradually slows down and stabilizes. Then, under the action of the crane, the precast column 12 can vertically descend to the appropriate position. Then, the employees fix the precast column 12 at a specific position, achieving the effect of adjusting and limiting the position of the precast column 12 by using the fitting limiting plate 136, so that the precast column 12 can descend at a vertical angle, avoiding slight swing of the precast column 12 during the descent. The swinging precast column is also prone to tilting of the precast column body, resulting in insufficient perpendicularity of the installed precast column and inability to perform secondary adjustment on the original basis, resulting in insufficient installation accuracy of the precast column.
[0032] Further, as Figures 1 to 6 shown, swing locks 113 are arranged on both side surfaces of the C-shaped docking housing 112. Angle blocks are fixedly connected to the corner positions of the C-shaped docking housing 112 and are arranged at one end of the steel wire sling 111. A docking rod 117 is arranged on one side surface of the C-shaped docking housing 112. A docking groove 118 is formed on the outer surface of the C-shaped docking housing 112 and at the side edge position of the docking rod 117. A motor is arranged on the inner surface of the C-shaped docking housing 112. A swing push arm one 114 is fixedly connected to the output end of the motor. One end of the swing push arm one 114 is swing-connected to a fitting plate 115. A hollow anti-slip strip 116 is fixedly connected to the outer surface of the fitting plate 115. A limiting track 131 is fixedly connected to the top surface of the lapping plate 13. The bottom surface of the slider 133 is movably sleeved on the top surface of the limiting track 131.
[0033] During operation, the C-shaped docking housing 112 is sleeved on the outer surface of the precast column 12. The docking rod 117 on the outer surface of the C-shaped docking housing 112 is docked and limited with the docking groove 118, so that the C-shaped docking housing 112 will not be misaligned in position. The two groups of C-shaped docking housings 112 are firmly fixed on the outer surface of the precast column 12 by cooperating with the swing lock 113. At the same time, the motor on the inner wall surface of the C-shaped docking housing 112 drives the swing push arm 114 to push the fitting plate 115, and then the fitting plate 115 and the hollow anti-slip strip 116 on the outer surface are closely attached to the outer surface of the precast column 12, increasing the anti-slip force between the fitting plate 115 and the precast column 12 and also enhancing the stability of the precast column 12.
[0034] Working principle: The C-shaped docking housing 112 is sleeved on the outer surface of the precast column 12. The docking rod 117 on the outer surface of the C-shaped docking housing 112 is docked and limited with the docking groove 118, so that the C-shaped docking housing 112 will not be misaligned in position. The two groups of C-shaped docking housings 112 are firmly fixed on the outer surface of the precast column 12 by cooperating with the swing lock 113. At the same time, the motor on the inner wall surface of the C-shaped docking housing 112 drives the swing push arm 114 to push the fitting plate 115, and then the fitting plate 115 and the hollow anti-slip strip 116 on the outer surface are closely attached to the outer surface of the precast column 12, increasing the anti-slip force between the fitting plate 115 and the precast column 12 and also enhancing the stability of the precast column 12.
[0035] The C-shaped docking housing 112 is sleeved on the outer surface of the precast column 12 and then sleeved on the surface of the suspension rod 11 by a crane to lift the precast column 12. At the same time, the steel wire sling 111 on the outer surface of the suspension rod 11 pulls the C-shaped docking housing 112. Since the installation position of the C-shaped docking housing 112 is biased towards the top edge position of the precast column 12, the center of gravity of the precast column 12 is always located at the bottom of the C-shaped docking housing 112, achieving the effect that the lower the center of gravity of an object, the more stable its reaction to external forces and the less likely it is to tip over or shake. Under the center of gravity of the precast column 12, the precast column 12 always remains in a vertical state.
[0036] When hoisting the precast column 12, move the lap joint plate 13 to the position where the precast column 12 needs to be installed. Cooperate with the rotation of the motor 132, so that the slider 133 on the surface of the output end of the motor 132 moves in the direction of fitting the limit plate 136. Then, through the support rod 135 and the swing push arm II 134 on the outer surface of the slider 133, push the fitting limit plate 136. At the same time, cooperate with the contact between the inner wall surface of the fitting limit plate 136 and the bottom surface of the precast column 12. Then, use the shape of the fitting limit plate 136 to control the swing angle and swing amplitude of the precast column 12, so as to prevent the swing amplitude of the precast column 12 from expanding due to inertia. As the two fitting limit plates 136 continuously close and approach, gradually stabilize the swinging precast column 12, so that the precast column 12 can vertically descend to the appropriate position under the action of the crane, and then the employees fix the precast column 12 at a specific position. It achieves the effect of adjusting and limiting the position of the precast column 12 by using the fitting limit plate 136, so that the precast column 12 can descend at a vertical angle, avoiding the slight swing of the precast column 12 when it is falling. The swinging precast column is also prone to the inclination of the precast column body, resulting in insufficient perpendicularity of the installed precast column and inability to perform secondary adjustment on the original basis, resulting in insufficient installation accuracy of the precast column.
[0037] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
