Among the construction methods, the precasting construction method has been successfully applied to various construction engineering construction because of its advantages of excellent structure quality, safe and rapid construction, economic and reasonable construction cost, etc. The precasting method is a precasting device which is used for manufacturing a steel bar structure and pouring concrete at the periphery of a precasting plant or a construction site by a standardized operation flow and a modularized mould, and quickly producing precise columns, beams, plates and the like in a large scale. Precast devices produced in a precast plant or at the periphery of a construction site are assembled on the construction site through precise handling management and assembling work. Therefore, the workload in a construction site can be reduced to the minimum, the manpower and the construction time are reduced, the construction period is effectively shortened, and the construction quality is ensured. In addition, the precasting construction method can reduce or avoid the construction on the outer wall scaffold, thereby greatly improving the construction safety.

The conventional precasting method is to construct a structure upward in a layer-by-layer manner, and thus is still limited in construction speed, and if the precasting structure can be performed in multiple layers, it is possible to greatly reduce man-hours. The multi-layer precast construction method needs to place and fix the multi-layer precast columns on the column body arranged on the ground. Because the length of multilayer precast column is longer, therefore both are difficult accurate alignment when joining to the crooked problem of precast column body easily produces. Therefore, it is desired to overcome the above problems while manufacturing a multilayer precast structure.

Please refer to fig. 2B. According to the embodiment of the present invention, the positioning apparatus 1 further includes a horizontal adjustment mechanism 40 and an urging member 50. And a portion of the leveling mechanism 40 can be inserted into the gap G between the precast column structure 6 and the column body 8. The horizontal adjustment mechanism 40 includes a positioning member 42 and an urging member 50. The positioning member 42 is detachably fixed above the cylinder 8. The pushing element 50 is detachably inserted through the positioning element 42 and configured to be driven to face and push against the first cylindrical surface 62 of the precast column structure 6, so as to finely adjust the horizontal position of the precast column structure 6 along the moving direction of the pushing element 50.

The positioning member 42 further includes a base 46, a plate 48 and a hook 49. The plate 48 is fixed on the base 46 and has a through hole 482 for the pushing element 50 to pass through. A hook 49 extends horizontally from one end of the base 46 and is releasably engaged with the free end of a reinforcement bar 84 projecting from the top surface 82 of the column 8. In this manner, the positioning member 42 can be detachably fixed above the column 8. In one embodiment, the through hole 482 of the plate 48 is provided with threads, and the pushing member 50 is externally provided with threads 52. An operator may apply a torque to the pushing element 50 to rotate the pushing element 50 to push directly towards the precast column structure 6. When the pushing-against part 50 is inserted into the through hole 482, the thread in the through hole 482 is engaged with the thread 52 of the pushing-against part 50. In an embodiment, the leveling mechanism 40 further includes a pressing element 44 detachably disposed between the pressing element 50 and the first cylindrical surface 62 of the pre-cast pillar structure 6. In the present embodiment, the positioning member 42 further includes two third extending plates 47 respectively connected to two opposite sides of the base 46 and the plate 48. The third extension plate 47 is triangular in shape and serves to increase the structural strength of the positioning member 42.

When the inclination adjusting mechanism 30 and the horizontal adjusting mechanism 40 provided by the invention are used for adjusting the horizontal and inclination angles of the precast column structure 6, the calibrator and the target of taiwan patent publication I456166 and the measuring method thereof can be used for determining whether the adjusted angle is correct. In particular, the calibrator includes a light source that is adjustable to direct emitted light in a vertical direction. The target piece is provided with a front surface and a back surface which are opposite to each other, and the front surface is marked with the target. The markers are positioned near the lower side of the column 8 and the target is positioned near the upper side of the precast column structure 6. When light emitted from the light source in the vertical direction is emitted to the center of the target, the precast column structure 6 is erected on the construction surface.

The following description of embodiments of the invention discloses a positioning method using the positioning apparatus 1 of fig. 1 to mount a precast column structure 6 to a column body 8. Referring to fig. 1 and 2B, first, the precast column structure 6 is installed on the column body 8, and a gap G is reserved between the precast column structure 6 and the column body 8 by temporarily engaging the reinforcing bars through the reserve pipes 64. Next, the tilt adjusting mechanisms 30 of the positioning apparatus 1 as described above are provided on the precast column structure 6 and each of the four faces of the column body 8 (for example, the first and third cylindrical faces 62 and 66 of the precast column structure 6 and the second and third cylindrical faces 80 and 86 of the column body 8 shown in fig. 2B), respectively. At this time, the opposite ends of the tilt adjusting mechanism 30 are connected to the first fixing element 10 and the second fixing element 20, respectively, and the hook 49 of the positioning element 42 of the horizontal adjusting mechanism 40 is engaged with the free end of the reinforcing bar 84 of the column 8.

Please refer to fig. 3, which is a second schematic diagram of the positioning apparatus 1 for mounting the precast column structure 6 to the column body 8 in fig. 1. Next, the leveling mechanism 40 is driven to cause the leveling mechanism 40 to face and push against the precast column structure 6, thereby causing the precast column structure 6 to move slightly horizontally relative to the column body 8 such that the precast column structure 6 is aligned with the side of the column body 8. In this embodiment, the operator applies a torque force to the adjustment abutting element 50 to move the abutting element 50 toward the first cylindrical surface 62, so as to push the precast column structure 6 to move, so that the precast column structure 6 is aligned with the opposite outer surface of the column body 8. In the present embodiment, two horizontal adjusting mechanisms 40 are disposed on the first cylindrical surface 62, and the two horizontal adjusting mechanisms 40 can be used to adjust the horizontal position of the precast column structure 6 simultaneously or sequentially. Furthermore, when the horizontal position of the first cylindrical surface 62 is adjusted by the two horizontal adjusting mechanisms 40, the two horizontal adjusting mechanisms 40 can be moved to the other side of the precast column structure 6 (for example, the third cylindrical surface 66 of the precast column structure 6), and the operator can sequentially move the setting position of the horizontal adjusting mechanism 40 according to the position of the actual precast column relative to the column body 8 and adjust the horizontal position of the precast column structure 6 and the column body 8 by using the plurality of horizontal adjusting mechanisms 40.

Referring to fig. 4, a third schematic diagram of the positioning apparatus 1 for mounting the precast column structure 6 to the column body 8 of fig. 1 is shown. The operator removes the leveling mechanism 40 and then drives the tilt adjusting mechanism 30 to adjust the tilt angle of the precast column structure 6 with respect to the column body 8 such that the precast column structure 6 is aligned with the column body 8 in the vertical direction. In the present embodiment, the operator applies a torque force to the driving member 36 to rotate the driving member 36, so as to drive the first screw 32 and the second screw 34 to move. Since the first screw 32 is pressed against the first extension plate 14 of the first fixing member 10, when the first screw 32 moves, the first screw pushes against the first extension plate 14 and adjusts the inclination of the first extension plate, so as to align the precast column structure 6 with the column body 8. In addition, the tilt adjusting mechanisms 30 may be disposed on four sides of the precast column structure 6 and the column body 8, and a user may sequentially use the tilt adjusting mechanisms 30 to adjust according to the position of the actual precast column structure 6 relative to the column body 8.

During the adjustment using the tilt adjustment mechanism 30 and the leveling mechanism 40, the calibration device and the target and the measurement method thereof can be used simultaneously to measure whether the precast column structure 6 is aligned with respect to the column body 8.

In addition, the sequence of steps for driving the tilt adjustment mechanism 30 and driving the leveling mechanism 40 may be changed according to actual requirements. For example, in the above embodiment, the horizontal adjustment mechanism 40 may be initially actuated, the horizontal adjustment mechanism 40 may be removed after completion, and the tilt adjustment mechanism 30 may be actuated. In one embodiment, the tilt adjustment mechanism 30 may be actuated before the leveling mechanism 40 is installed and actuated, and then the leveling mechanism 40 may be removed after the adjustment is completed. Alternatively, the tilt adjusting mechanism 30 and the leveling mechanism 40 may be installed first, the tilt adjusting mechanism 30 may be driven, the leveling mechanism 40 may be driven, and the leveling mechanism 40 may be removed after alignment. In another embodiment, the leveling mechanism 40 and the tilt mechanism 30 may also be driven simultaneously.

Fig. 5 is a fourth schematic diagram of the positioning apparatus 1 for mounting the precast column structure 6 to the column body 8 in fig. 1. In this step, the operator installs the form 90 between the four faces of the precast column structure 6 and the column body 8 shown in fig. 2A to close the gap G, and then fills the gap G between the precast column structure 6 and the column body 8 with cement mortar 9. In detail, a plurality of reserve pipes 64 are provided in the precast column structure 6 in advance, wherein one end of each of the plurality of reserve pipes 64 is disposed in a side surface (e.g., the first cylindrical surface 62) of the precast column structure 6, and the other end thereof is disposed in a bottom surface 68 (shown in fig. 1) of the precast column structure 6. Cement mortar 9 is then injected under pressure from the end of the reserve pipe 64 in the side of the precast column structure 6 (e.g., the first cylindrical surface 62) to the gap between the precast column structure 6 and the column 8. Thus, the precast column structure 6 can be effectively fixed on the column body 8 through the gap between the precast column structure 6 and the column body 8 solidified by the cement mortar 9.

Please refer to fig. 6, which is a five-part detachable tilt adjusting mechanism 30 using the positioning apparatus 1 of fig. 1 for mounting the precast column structure 6 on the column body 8. The form 90 of fig. 5 can be removed after the cement mortar 9 has set in the gap between the precast column structure 6 and the column body 8. In this manner, the step of disposing the precast column structure 6 on the column body 8 is completed. In addition, the first fixing member 10, the second fixing member 20 and the tilt adjusting mechanism 30 can be detached and reused.

Referring to fig. 7, fig. 8A and fig. 8B, fig. 7 is an exploded schematic view of a positioning apparatus 1 for mounting a precast column structure 6 on a column body 8 according to another embodiment of the present invention, fig. 8A is one of schematic views of the positioning apparatus 1 for mounting the precast column structure 6 on the column body 8 using fig. 7, and fig. 8B is a partially enlarged schematic view of the positioning apparatus 1 of fig. 8A. The present embodiment is similar to the positioning structure of the previous embodiments. However, there is a difference in that the tilt adjusting mechanism 30 is fixed to the first fixing member 10 and the second fixing member 20 in a pivot manner. In detail, the first screw 32 has a first pivot joint 33, the second screw 34 has a second pivot joint 35, the first fixing member 10 has a first pivot base 13, and the second fixing member 20 has a second pivot base 23. The first pivot joint 33 and the second pivot joint 35 are fixedly pivoted on the first pivot base 13 and the second pivot base 23 through the first rotating shaft 19 and the second rotating shaft 29. The axes of the first and second shafts 19, 29 are substantially perpendicular to the direction of extension of the precast column structure 6. Therefore, when the driving member 36 is rotated by an external force, the driving member 36 drives the first screw rod 32 to move, and since the first screw rod 32 is pivoted to the first fixing member 10, the first screw rod 32 can pivot to drive the precast column structure 6 to slightly rotate, so that the precast column structure 6 is aligned on the column body 8.

The following description of embodiments of the invention discloses a positioning method using the positioning apparatus 1 of fig. 7 to mount a precast column structure 6 to a column body 8. Please refer to fig. 7, fig. 8A and fig. 8B. First, the positioning device 1 is provided on four sides of the precast column structure 6 and the column body 8, respectively. Next, please refer to fig. 9, which is a second schematic diagram of the positioning apparatus 1 for mounting the precast column structure 6 on the column body 8 in fig. 7. The horizontal adjusting mechanism 40 is driven to push the pushing part 50 of the horizontal adjusting mechanism 40 towards the precast column structure 6, so that the precast column structure 6 moves horizontally relative to the column body 8 to align the precast column structure 6 with the side surface of the column body 8. Please refer to fig. 10, which is a third schematic diagram of the positioning apparatus 1 for mounting the precast column structure 6 to the column body 8 in fig. 7. The horizontal adjustment mechanism 40 is detached and the tilt adjustment mechanism 30 is driven to adjust the tilt angle of the precast column structure 6 with respect to the column body 8 so that the precast column structure 6 is aligned with the column body 8 in the vertical direction. Please refer to fig. 11, which is a fourth schematic diagram of the positioning apparatus 1 for mounting the precast column structure 6 to the column body 8 in fig. 7. The operator sets the formwork 90 in the space between the structure 6 and the column 8 and then fills the space between the precast column structure 6 and the column 8 with cement mortar 9. Referring to fig. 12 and 13, fig. 12 is a fifth schematic view of the positioning apparatus 1 for mounting the precast column structure 6 to the column body 8 shown in fig. 7, and fig. 13 is a perspective view of the precast column structure 6 and the column body 8 after the positioning apparatus 1 for mounting the precast column structure 6 to the column body 8 shown in fig. 7 is mounted. After the cement mortar 9 is solidified, the formwork 90 can be disassembled. In this manner, the step of mounting the precast column structure 6 to the column body 8 is completed. The tilt adjustment mechanism 30 may then also be removed for future reuse.

Please refer to fig. 13. After the precast column structure 6 is completely installed, a plurality of inclined supporting members 7 may be further disposed on the first cylindrical surface 62, the third cylindrical surface 66, and the other cylindrical surfaces of the precast column structure 6, so as to improve the fixing property of the precast column structure 6 after the inclination adjusting mechanism 30 and the horizontal adjusting mechanism 40 are disassembled. For example, when four inclined supporting members 7 are disposed on four sides of the pillar preform structure 6, the pillar preform structure 6 can receive three axial forces to prevent the pillar preform structure 6 from being displaced during the engineering process. Specifically, in the present embodiment, the positioning apparatus 10 further includes a top seat 70 and a bottom seat 72, the top seat 70 is fixed on the first cylindrical surface 62 and located above the first fixing member 10, and the bottom seat 72 is disposed on the ground. One end of the inclined supporting member 7 is pivotally mounted on the top seat 70 above the first fixing member 10, and the opposite end of the inclined supporting member 7 is pivotally mounted on the base 72 on the ground.
