Auxiliary mounting equipment for tie beam steel bars of lower structure of fabricated bridge

ZHAO HU / DU YUBIN / ZHAO WENJING / PAN GUANGYAO

The invention relates to the technical field of bridge pouring, in particular to assembly type bridge lower structure tie beam steel bar auxiliary installation equipment which comprises a steel bar base, a lifting mechanism and an auxiliary mechanism. A transverse plate and a pushing plate are matched with each other to push a steel ring in the left-right direction and the front-back direction firstly, it is guaranteed that the steel ring is tightly attached to a placed steel bar, and then an arranged swing plate enables the steel bars at the four corners in a steel reinforcement cage to be tightly attached to the steel ring under the action of a control air cylinder; the problem that the welding effect becomes poor due to the fact that the steel rings are not tightly attached to the steel bars is solved, the lifting sets move up and down along the steel bars through cooperation of the four sets of opposite lifting pieces, subsequent steel ring placing and welding are facilitated, and the welding efficiency is improved. And the steel rings are received and separated through the placing columns, so that subsequent taking and placing are facilitated, the working efficiency is improved, and the labor cost is reduced.

本发明涉及桥梁浇筑技术领域，特别涉及一种装配式桥梁下构系梁钢筋辅助安装设备，包括钢筋底座、升降机构和辅助机构。本发明中设置的横向板以及推动板相互配合首先对钢圈的左右方向以及前后方向进行推动，保证其与放置的钢筋紧贴，之后设置的摆动板在控制气缸的作用下使得钢筋笼内四个拐角处的钢筋与钢圈紧贴，之后再由外部现有的焊接机构进行焊接，避免因钢圈与钢筋之间未紧贴而导致焊接效果变差的问题，以及通过四组相对的升降件之间的配合实现升降组沿着钢筋上下移动，便于后续对钢圈的放置以及对钢圈的焊接，以及通过放置柱对钢圈进行承接隔开，便于后续的取放，从而提高了工作的效率，减少人工成本。
