[0041] The present invention provides a construction method of a PC column reinforcement positioning control device, comprising the following steps:

[0042] S1. Install the support frame 1 on the upper part of the cast-in-place foundation of the PC column.

[0043] S2. Adjust the positions of the two movable upper beams 2 and the two movable lower beams 3 so that the distance of the clamping spaces on the two movable upper beams 2 and the two movable lower beams 3 is adapted to the distance between the column reinforcements on the opposite sides of the PC column.

[0046] S5, the locking beam 5 is detachably installed on the movable upper beam 2 and the movable lower beam 3, so that the locking beam 5 is pressed against the side of the multiple vertical main reinforcements 6 on the multiple movable seats 4 away from the movable seats 4.

[0047] The PC column reinforcement positioning control device of the present invention can be used for positioning PC columns with different cross-sectional sizes, different reinforcement specifications, reinforcement quantities, and reinforcement positions.

[0048] The PC column reinforcement positioning control device of the present invention mainly consists of three parts: a supporting frame, a movable upper beam, a movable lower beam, and a movable seat.

[0049] The support frame is an integral frame. The movable upper beam and the movable lower beam are bidirectional reinforcement positioning devices for the column, which can slide in both directions to fix a row of vertical main reinforcements in the same direction (the first horizontal direction or the second horizontal direction). The movable seat is a detailed adjustment device, which is suitable for micro-adjustment of the same row of reinforcements with different specifications.

[0050] After the steel bars of the cast-in-place foundation at the bottom of the PC component to be installed are tied (generally the first-floor columns), before pouring concrete, first straighten the PC column anchor steel bars above the pouring surface, and then install the PC column reinforcement positioning control device of the present invention (the anchoring length of the cast-in-place column steel bars and the PC column is generally about 20 cm, and the specific length is determined according to the steel bar specifications).

[0051] After the support frame is fixed, adjust the position of the movable upper beam, movable lower beam and movable seat. After the position of the vertical main reinforcement is fixed, pour the concrete, and after curing until the strength meets the requirements and the vertical main reinforcement basically does not deviate, the positioning device can be retracted and the mud can be cleaned for the next use.

[0052] The PC column reinforcement positioning control device of the present invention is installed on the upper part of the vertical main reinforcement. The positions of the movable upper beam and the movable lower beam are adjusted according to the cross-sectional size of the column and the spacing of the reinforcement bars. The position of the component movable seat is adjusted according to the specifications of the reinforcement bars. After the adjustment is completed, the device is fixed and concrete pouring is carried out.

[0053] After pouring concrete, the device can be recovered when the concrete strength meets the requirements. At this time, the position of the steel bars has been fixed, and the subsequent PC columns can be directly hoisted, avoiding the problem of the PC column and the lower bars being unable to connect due to the spacing and position of the steel bars.

[0054] The PC column reinforcement positioning control device of the present invention can protect the quality of the finished product of the vertical main reinforcement and avoid forced position adjustment due to the deviation of the vertical main reinforcement steel bars of the cast-in-place foundation and the inability to connect with the upper PC column.

[0055] The PC column reinforcement positioning control device of the present invention is suitable for PC column components with different cross-sectional sizes, different reinforcement specifications, quantities and positions, and can be repeatedly utilized.

[0056] The PC column reinforcement positioning control device of the present invention can be mass-produced and processed, and can be used in a turnover manner, with lower cost.
