Steel structure splicing bridge and method

CHEN JIANHUA / AN JINGJIE / XIE XIAOHUI

The invention discloses a steel structure spliced bridge which comprises a first bridge body and a second bridge body and further comprises a plurality of anchoring hanging brackets, each anchoring hanging bracket is in sliding connection with a sliding seat through a supporting ball seat, and one anchoring hanging bracket is connected with a second middle beam. The first middle beam and the driving part are connected to the second middle beam and used for driving the first middle beam on the two sides of the second middle beam to approach the edge beam, a driving frame is fixedly connected to the anchoring hanging bracket located at the bottom of the second middle beam, and the driving part comprises a driving unit arranged on the driving frame and telescopic units connected to the two sides of the second middle beam; the telescopic unit is attached to the side portion of the first middle beam to drive the first middle beam to get close to the side beam, the first middle beam is driven through the driving piece, and therefore the phenomenon that the first middle beam gets stuck after getting close to the second middle beam is prevented; and the situation that the first middle beam is close to the second middle beam for a long time and is far away from the boundary beam, so that the boundary beam bears the vehicle pressure for a long time and is desoldered and cracked is avoided.

本发明公开了一种钢结构拼接桥梁，包括第一桥体和第二桥体，还包括多个锚固吊架，每个锚固吊架通过支撑球座与滑座滑动连接，其中一个锚固吊架上连接有第二中梁；第一中梁和驱动件，连接在第二中梁上用于驱动第二中梁两侧的第一中梁向边梁方向靠近，其中，位于第二中梁底部的锚固吊架上固定连接有驱动架，驱动件包括设置在驱动架上的驱动单元以及连接在第二中梁两侧的伸缩单元，伸缩单元与第一中梁侧部贴合实现驱动第一中梁向边梁方向靠近,通过驱动件实现对第一中梁的驱动，以防止第一中梁在向第二中梁靠近后存在卡壳现象，避免了第一中梁长期靠近第二中梁而距离边梁较远导致边梁承受车辆压力时间较久发生脱焊开裂的情况。
