Located between the ends of the beam, the ends corresponding to the rebar are placed between the ends of the precast beam, the ends generally being horizontal arcs. In the actual construction, due to the complex site conditions, external impact and pressure, etc., the end of the horizontal arc-shaped rebar will be deformed, and the end of the rebar after deformation will be adjusted horizontally before the wet joint construction. Otherwise, the engineering quality of the wet joint will be greatly affected, and the support of the entire bridge process will be greatly affected. The joint construction space is small, there are certain difficulties in adjusting the rebar, and manual adjustment often takes time and effort.

The purpose of the present invention is to realize the adjustment of the rebar end during the wet joint, which is convenient and quick as a whole, thereby ensuring the construction quality, and improving the waterproofness and overall stability of the bridge wet joint rebar. To provide an adjustment tool.

The present invention adopts the following technical means.
The bridge wet joint rebar adjustment tool includes a pry bar and a hook, one end of the pry bar is provided with an L-shaped fixed steel plate, the L-shaped fixed steel plate is provided with a rotating shaft, and one end of the pry bar is connected to the L-shaped fixed steel plate through the rotating shaft. A suspension lug is provided on the pry bar, and the upper end of the hook is connected to the suspension lug via a suspension ring.

It further includes a reflective sensor, said reflective sensor is fixed at the end of the lanyard near the hook, and when the lanyard is in a vertical position, the reflective sensor is horizontally installed and the transmitting end is toward one end of the pryer.

further comprising a self-adjusting member, said self-adjusting member comprising a bi-directional stepping motor, a lanyard, a PLC and a power supply, said bi-directional stepping motor being fixed to a pry bar and one end of the lanyard being connected to the output shaft of the bi-directional stepping motor and the other end is connected to the end of the hook.

The adjustment tool including the automatic adjustment member is used in combination, and further includes a balance bar, and suspension rings fixed to hooks are provided at both ends of the balance bar.

A restriction is provided at the other end of the pry bar.

In the present invention, a pry bar is provided, a rotatable hook is hung in the middle of the pry bar, one end of the pry bar is in contact with one end of the wet joint, the other end is manually held by the operator, and the hook is the rebar to be leveled. Hooked on the end, the operator uses the lever principle to move the end of the rebar upward until it reaches a horizontal position, so that the horizontal adjustment of the end of the rebar in each wet joint can be realized labor-saving and quickly be able to.
