[0031] At least one of the first rod 3, the second rod 4, and the support rod 6 is a telescopic structure. In this embodiment, the first rod 3, the second rod 4, and the support rod 6 are all telescopic structures. Specifically, the telescopic structure can be an inner sleeve rod and an outer sleeve rod that slide against each other and are fixed by a locking structure; it can also be an electric telescopic rod, etc. The appropriate structure can be flexibly selected based on the common technical knowledge of those skilled in the art, and this utility model does not impose any limitations. In this embodiment, each rod is a telescopic structure, which can be used in various complex steel frame construction environments. The second rod 4 and the support rod 6 work together to form a positioning reference, and the precast column is moved and adjusted by the first rod 3 extending into the frame, reducing the frequency of personnel entering the frame. It has wide applicability and is easy to promote.

[0032] In this embodiment, the adjustment unit also includes an observation mirror 8, which is connected to the support rod 6. Preferably, the observation mirror 8 is rotatably connected to the support rod 6 to observe blind spots during construction. The observation mirror 8 can be a metal mirror, used to assist in reflecting the ground and the field of vision of the rebar connection area, to monitor the trajectory of the precast column falling in real time, the alignment status of the holes at the bottom of the precast column and the rebar, to reduce alignment deviation, to avoid construction personnel frequently climbing or entering the scaffold, to reduce the risk of working at height, and to improve construction safety.

[0033] In this embodiment, the first connecting part 1 is detachably connected to the precast column, and the second connecting part 2 is detachably connected to the reserved reinforcing bar. The second connecting part 2 includes a connecting component 22 and two arc-shaped reinforcing bar clamps 21. The two reinforcing bar clamps 21 are movably connected and fastened to the outside of the reserved reinforcing bar through the connecting component 22. The second rod 4 is connected to the corresponding reinforcing bar clamp 21. Preferably, the two reinforcing bar clamps 21 are hinged to each other through a hinge axis, and connecting ears are provided on the edges away from the hinge axis.

In this embodiment, the first connecting part 1 can have the same structure as the second connecting part, and its size can be adjusted according to the usage requirements. The first connecting part 1 includes two arc-shaped precast column clamps and fastening components. The two precast column clamps are hinged to each other and each precast column clamp is provided with a connecting plate. The fastening components include fastening bolts and fastening nuts. After the fastening bolts are inserted into the connecting plates, they are connected with the fastening nuts to lock them. The first rod body 3 is detachably connected to the corresponding precast column clamp. The outer side of the corresponding precast column clamp has a first locking post. The first locking post has a first slot 13 to insert the first rod body 3.

[0034] In this embodiment, the adjustment unit further includes a horizontal positioning component 7, which includes at least one level 72. The level 72 is connected to either the first rod 3 or the second rod 4. During construction, it is typically necessary to align the bottom hole of the precast column with the fixed pre-reserved reinforcing steel. Preferably, the rod connected to the pre-reserved reinforcing steel is fitted with the level 72. In this embodiment, the second rod 4, located below, is connected to the pre-reserved reinforcing steel via a second connecting part 2. The second rod 4 is fitted with the level 72, while the first rod 3 is selectively fitted with the level 72 according to construction requirements.

[0035] In this embodiment, multiple levels 72 are arranged in pairs, perpendicular to each other. The biaxial levels 72 establish a positioning horizontal plane to ensure the horizontal positioning effect of the calibration structure.

[0036] In this embodiment, the horizontal positioning component 7 is connected to the second rod 4. The horizontal positioning component 7 includes a positioning disk 71 connected to the second rod 4, and a level 72 connected to the positioning disk 71. The calibration structure is an alignment mark located in the center of the positioning disk. Preferably, the positioning disk 71 has two mutually perpendicular mounting slots to accommodate the level 72. The surface of the alignment mark is covered with a laser reflective layer to facilitate quick confirmation by personnel whether the laser line is aligned with the alignment mark.

[0037] The construction method of this utility model includes the following steps:

[0038] Hold the support rod 6 and fix its bottom against the ground to secure it. Connect the second connecting part 2 to the reserved steel bar. Adjust the level of the second rod 4 and fix it to the support rod 6.

[0039] Connect the first connecting part 1 to the precast column, activate the laser emitting component 5, and move the precast column through the first rod 3 until the landing point of the laser line coincides with the calibration structure, thereby achieving the alignment of the precast column and the reserved steel bars.

[0040] The specific construction process for aligning the precast columns and reserved reinforcing bars in this embodiment is as follows:

[0041] S1. Component preparation: Select suitable first connecting part 1 and second connecting part 2 according to the specifications and dimensions of the precast column and reserved steel bars, assemble the first connecting part 1 with the first rod body 3, and assemble the second connecting part 2 with the second rod body 4;

[0042] S2. Positioning of reserved steel bars: Two steel bar clamps 21 are spliced ​​together to be fitted onto the outside of the joint end of the reserved steel bars and locked by the connecting components. The bottom of the support rod 6 is fixed to the ground. The second rod is movably inserted into the support rod 6. The level of the second rod 4 is adjusted by the level instrument 72. After the level of the second rod 4 is adjusted, the tightening bolt is inserted through the support rod 6 to be pressed against the groove of the second rod 4. The second rod 4 can be erected by the support rod 6 and the reserved steel bars. The tightening bolt can lock the adjusted second rod 4.

[0043] S3. The pre-cast column clamps are spliced ​​together to fit over the outside of the pre-cast column and fixed with bolts and nuts. The first rod 3 is movably inserted into the support rod 6 and positioned above the second rod 4. The laser emitting component 5 is activated, and the first rod 3 drives the bottom of the precast column to align with the pre-cast steel bar until the laser line emitted by the laser emitting component 5 aligns with the alignment mark. The first rod 3 is then locked to the support rod 6 with the tightening bolts. The nuts are loosened to release the lock on the precast column, allowing it to slide relative to the first connecting part 1. That is, the precast column falls along the inside of the first connecting part 1 to connect with the pre-cast steel bar. When the bottom of the precast column contacts the second connecting part 2, the second connecting part 2 is disassembled to allow the precast column to continue falling. In this embodiment, the first connecting part 1 can serve as a guide channel when the precast column falls to ensure the positioning accuracy of the precast column and the steel bar.

[0044] Example 2:

[0045] like Figure 7 As shown, in this embodiment, the first connecting part 1 and the second connecting part 2 have different structures. The first connecting part 1 includes two arc-shaped precast column clamps, and each precast column clamp has a circumferential locking groove 11 on its outer side. The first connecting part 1 also includes a locking ring 12, which can be sleeved on the outside of the spliced ​​circumferential locking groove 11 to fix the first connecting part 1 to the outside of the precast column. The first rod 3 can be inserted into the first slot 13 on the outside of the corresponding precast column clamp for detachable connection. Preferably, the lower outer diameter of the precast column clamp is smaller than the upper outer diameter to form the circumferential locking groove 11. The locking ring 12 is made of elastic material and can be disassembled by shearing or other methods.

[0046] In this embodiment, the spacing between the first connecting part 1 and the second connecting part 2 is appropriate. First, the positioning of the bottom of the precast column and the reserved steel bar is completed by the precast column and reserved steel bar alignment device. At this time, the bottom of the precast column and the top of the reserved steel bar are in contact or close to each other. Then, the locking ring 12 is removed so that the precast column falls vertically to complete the positioning and connection of the precast column and the reserved steel bar.

[0047] This invention establishes a calibration level plane through a double level 72 connected to the second rod 4, ensuring the horizontal reference of the calibration structure. Then, the laser emitting component 5 cooperates with the calibration structure to achieve precise positioning. The observation mirror 8 can reflect blind spots, facilitating personnel observation. All rods are telescopic structures, which can be applied to the construction of various complex steel frame structures and reduce the frequency of personnel entering the frame structure, thereby improving the efficiency of positioning construction. The structure is simple, the processing cost is low, the operation is convenient, and it can be reused.

[0048] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
