Unit type bridge expansion device and mounting method thereof
The invention provides a unit type bridge expansion device. The bridge comprises a multi-section bridge main body structure, a plurality of sections of expansion joints are arranged between the adjacent bridge main body structures; an embedded steel plate is horizontally arranged in each bridge column structure. A plurality of embedded steel bars are arranged below the embedded steel plate; a telescopic device is arranged above the side, close to the expansion joint, of the embedded steel plate; the telescopic device comprises special-shaped steel. An embedded bolt penetrating through the special-shaped steel and the embedded steel plate is arranged above the special-shaped steel. The high-strength low-shrinkage concrete expansion joint is simple in structure, reasonable in design, convenient to replace, high in strength, good in construction quality, high in economical efficiency and innovative, and traffic influences are reduced by the aid of the high-strength low-shrinkage concreteexpansion joint.
本发明提供一种单元式桥梁伸缩装置，包括多段桥梁主体结构，相邻桥梁主体结构之间设置有多段伸缩缝，每个桥梁柱体结构内部水平设置有预埋钢板，所述预埋钢板下方设置有若干个预埋钢筋，预埋钢板靠近伸缩缝的侧上方设置有伸缩装置，所述伸缩装置包括异形钢，所述异形钢上方设置有贯穿异形钢及预埋钢板的预埋螺栓，两个异性钢之间设有橡胶止水带，每个异形钢上设有伸缩缝预留槽，所述伸缩缝预留槽内填充有高强度低收缩混凝土层，本发明结构简单，设计合理，方便更换，强度高，施工质量好，经济型强且减小交通影响，具有创新性。
