Bridge expansion joint connecting and anchoring structure
The invention provides a bridge expansion joint connecting and anchoring structure which comprises a beam body, a beam body sealing end and an expansion joint device, wherein embedded anchor bars are arranged in the beam body and the beam body sealing end; the expansion joint device is arranged on the beam body sealing end and comprises deformed steel and expansion joint annular bars; concrete is poured on the beam body and the beam body sealing end; the expansion joint annular bars are in the concrete. The bridge expansion joint connecting and anchoring structure further comprises connecting steel bars, steel bar meshes and at least two pre-embedded steel plates, the two pre-embedded steel plates are arranged on the beam body and the beam body sealing end respectively, the bottom faces of the pre-embedded steel plates are connected with the pre-embedded anchor bars, the connecting steel bars are arranged on the two embedded steel plates in a crossing mode, the lower portions of the connecting steel bars are connected with the two embedded steel plates respectively, the upper portions of the connecting steel bars are connected with the expansion joint annular bars, and the steel bar meshes are arranged in the concrete and connected with the connecting steel bars and the expansion joint annular ribs respectively. The structure has the advantages of high error-tolerant rate and convenience in welding and anchoring operation.
本发明提供一种桥梁伸缩缝连接锚固结构，包括梁体、梁体封端和伸缩缝装置，梁体和梁体封端内均设置有预埋锚筋，伸缩缝装置设置在梁体封端上，伸缩缝装置包括异型钢和伸缩缝环形筋，梁体和梁体封端上浇筑混凝土，伸缩缝环形筋位于混凝土之内，桥梁伸缩缝连接锚固结构还包括：连接钢筋、钢筋网片和至少两个预埋钢板，两个预埋钢板分别设置在梁体、梁体封端上，预埋钢板的底面与预埋锚筋连接；连接钢筋跨设在两个预埋钢板上，连接钢筋的下部分别与两个预埋钢板连接，连接钢筋的上部与伸缩缝环形筋连接，钢筋网片设置在混凝土内，钢筋网片分别与连接钢筋、伸缩缝环形筋连接。本发明具有容错率大、便于焊接锚固操作的优点。
