The implementation steps of the scheme are as follows:

1. the method comprises the steps of embedding a support frame on the upper surface of a bridge pier poured section below a tie beam pouring section, installing an adjusting jack on the support frame, sequentially connecting the adjusting jack, a pull rod, a cantilever beam and a distribution bracket, supporting a tie beam template mechanism on the distribution bracket, and pouring the tie beam pouring section.

2. And removing the parts except the bottom die of the tie beam, driving the adjusting jacks to drive all the cantilever beams to move downwards, and driving the distribution bracket to move downwards, wherein the rest parts of the tie beam template mechanism, namely the bottom die of the tie beam, can be selectively removed according to the requirement.

3. The cantilever beam close to the rotating side of the distribution bracket stops moving downwards, the cantilever beam close to the free side of the distribution bracket continues moving downwards, the free side of the distribution bracket loses the support of the cantilever beam and then rotates to a vertical state around the rotating side, at the moment, the distribution bracket is not arranged at the bottom of the tie beam, and is arranged on the side face of the tie beam, so that when the pier template drives the distribution bracket to ascend, interference with the poured tie beam does not occur.

The beneficial effect of this scheme is:

1. the erection of the tie beam supporting mechanism belongs to high-altitude operation, and in order to realize the support of the distribution bracket, the distribution bracket is required to be supported by arranging the cantilever beam; in order to ensure the supporting effect, the cantilever beam needs to be arranged below the distribution bracket, but is arranged in such a way that the cantilever beam can prevent the distribution bracket from rotating when the distribution bracket rotates; in this scheme, drive the cantilever beam and reciprocate through setting up adjusting jack, avoid the cantilever beam to hinder the distribution support rotatory.

2. When the distribution bracket rotates, the manual standing is not needed to operate beside the tie beam, the adjusting jack is driven, the rotation of the distribution bracket can be realized under the action of gravity, the convenience and the rapidness are realized, and the construction safety is improved.

3. The bracket does not need to be dismantled, and after the distribution bracket rotates, the distribution bracket is not arranged at the bottom of the tie beam, but is arranged at the side surface of the tie beam, so that interference with the poured tie beam does not occur when the pier template drives the distribution bracket to ascend.

Further, the free side of the distribution bracket protrudes relative to the corresponding cantilever beam side, the free side of the distribution bracket can be connected with the steel cable, after the adjusting jack close to the free side of the distribution bracket is driven, the cantilever beam and the free side of the distribution bracket move downwards, the distribution bracket is in an inclined state, and the steel cable can sequentially bypass one side of the tie beam close to the rotating side, the lower side of the tie beam and be connected with the free side of the distribution bracket. After the tie beam pouring section is poured, the tie beam pouring section is matched with the adjusting jack for use, so that the rotation speed of the distributing bracket is reduced.

Specific:

firstly, an adjusting jack on the free side of a distribution bracket is driven to move downwards, a pull rod and a cantilever beam are driven to rotate downwards, the free side of the distribution bracket is driven to rotate downwards until the free side of the distribution bracket is flush with the side surface of the cantilever beam, namely, the free side of the distribution bracket is no longer protruded backwards relative to the cantilever beam on the rear side, at the moment, the cantilever beam still has a supporting effect on the distribution bracket, the distribution bracket is in an inclined state due to rotation, namely, gaps are formed between the distribution bracket and the bottom of a poured tie beam, at the moment, a plurality of steel ropes are prepared, the upper ends of the steel ropes are fixed on any structure above the cantilever beam, a worker stands on one side close to the rotating side of the distribution bracket, hangs the upper ends of the steel ropes on a mounting platform, a part of the steel ropes is placed in the gaps between the distribution bracket and the bottom of the poured tie beam, the lower ends of the steel ropes are pushed to the rotating side of the distribution bracket by rods such as steel bars, and then the other worker hooks the lower ends of the steel ropes on the free side of the distribution bracket.

If the steel cable is not penetrated from the rotating side of the distribution bracket to the free side, but is directly connected with the free side of the distribution bracket, after the distribution bracket rotates, the upper end of the steel cable is connected with the distribution bracket as well as the lower end of the steel cable is connected with the distribution bracket, and when the pier template mechanism drives the tie beam supporting structure to rise, the steel cable still can interfere with the tie beam, so that the rise of the tie beam supporting structure is prevented.

Then, the adjusting jack on the free side of the distribution bracket is driven continuously, so that the cantilever beam continuously moves downwards until the cantilever beam can not continuously support the free side of the distribution bracket any more, and meanwhile, a worker pulls the steel rope to slowly put down the free end of the distribution bracket, so that the distribution bracket is prevented from being damaged due to too fast rotation speed.

Finally, the bridge pier template mechanism drives the tie beam supporting mechanism to slide upwards, the upper end of the steel cable is always fixed on any structure above the cantilever beam in the whole process of upward sliding of the bridge pier template mechanism so as to reach a second tie beam pouring section, and the steel cable is pulled to enable the distribution bracket to rotate to be horizontal, otherwise, no other simple and safe method is adopted to enable the distribution bracket to rotate to be horizontal; at this time, the second tie beam is not cast, and when the steel cable is pulled, the steel cable and the distributing bracket cannot interfere with the tie beam.

Further, the tie beam template mechanism comprises a tie beam bottom die and two tie beam side dies, the tie beam bottom die is horizontally connected to the distribution bracket through bolts, the two tie beam side dies are respectively arranged on two sides of the tie beam, a corner sealing template is arranged between the two tie beam side dies, the corner sealing template is filled between one end of the bottom of the tie beam and the pier stud, a strip-shaped gap is formed between the tie beam bottom die and the pier stud after the corner sealing template is removed, the end part of the steel cable is placed in the strip-shaped gap, and when the steel cable passes through the lower side of the tie beam, the strip-shaped gap provides guidance for the steel cable. After the tie beam pouring section is poured, the tie beam side die and the corner sealing die plate are removed, a gap exists between the tie beam bottom die and the pier stud, the jack is adjusted to drive the cantilever beam to move downwards, the distribution support is in an inclined state due to rotation, the rope head at the lower end of the steel rope falls in the gap between the tie beam bottom die and the pier stud (because the end part of the steel rope is a metal buckle and is usually provided with a certain weight), so that the position of the end part of the steel rope is observed in the pushing process, the end part of the steel rope cannot be found, meanwhile, the strip-shaped gap provides guidance for the steel rope, and the lower end of the steel rope is smoothly pushed to the rotating side of the distribution support from the free side of the distribution support by the rod-shaped object.

Further, the support frame comprises a cross beam, a stand column and a pull rod, wherein the stand column is pre-buried in a poured section of the pier column, the cross beam is connected with the upper end of the stand column, the end part of the cross beam extends out of the pier template mechanism, and the adjusting jack is arranged at the end part of the cross beam. The arrangement increases the load of the cross beam due to the arrangement of the adjusting jack; in the process of adjusting the jack to drive the cantilever beam to move up and down, the cross beam shakes, so that impulse generated by the cantilever beam and the distribution bracket is born; the load and the ram of adjusting the jack and impulse that distribution support produced are vertical, compare in the direct pre-buried section that has watered of pier stud of crossbeam, and the pier stud bears the moment of flexure of crossbeam transmission, and this scheme gives the stand with load and impulse transmission on the crossbeam, and stand and load and impulse's direction are vertical, and the pier stud bears the axial force of stand transmission, no longer bears the moment of flexure, and then makes the bearing capacity of pier stud stronger.

After the rectangular plate clamps the cross beam, the rectangular plate provides vertical support for the cross beam, and in the process that the bridge pier template mechanism slides upwards, as the distribution bracket rotates to one side of the cross beam, the load on the side, close to the distribution bracket, of the cross beam is larger, and the cross beam tends to slide towards the side; if crossbeam and support conversion unit fixed connection, the gliding trend of crossbeam is prevented by support conversion unit, consequently crossbeam and support conversion unit hookup location and produce the deformation more easily, and in this scheme, the rectangular plate presss from both sides tight back with the crossbeam, allows the crossbeam to move horizontally to a certain extent, and then reduces the deformation of crossbeam.

Further, the distribution bracket comprises two main beams, a plurality of parallel secondary beams are arranged between the two main beams, and the main beams are connected with the cantilever beams. So set up, support the girder on the cantilever beam, connect two girders through the secondary beam, and then increase the holding surface of distribution support and tie beam template, and then increase the stability of structure.
