Spliced and widened bridge connecting device, and construction method and application thereof
The invention discloses a spliced and widened bridge connecting device, and a construction method and application thereof. The spliced and widened bridge connecting device comprises an old bridge flange plate, a new bridge flange plate, a transition butt strap and an asphalt concrete bridge floor; the upper end faces of the new bridge flange plate and the old bridge flange plate are each provided with an abutment opening, and the height of the inner side wall of each abutment opening is smaller than that of the outer side wall of each abutment opening; the new bridge flange plate and the old bridge flange plate are in lap joint through a plurality of transition butt straps, the transition butt straps are arranged in an abutment opening of the new bridge flange plate and an abutment opening of the old bridge flange plate, cushion layers are arranged between the bottoms of the transition butt straps and the bottoms of the abutment openings, gaps are formed between the two sides of the transition butt strap and the outer side wall of the abutment opening of the new bridge flange plate and between the two sides of the transition butt strap and the outer side wall of the abutment opening of the old bridge flange plate respectively, and deformation buffer layers are arranged in the gaps; and the asphalt concrete bridge deck is laid on the upper end faces of the transition butt strap, the new bridge flange plate and the old bridge flange plate. The problem that an existing connecting mode easily causes cracking of the bridge floor of the spliced and widened bridge is solved.
本发明公开了拼宽桥梁连接装置及施工方法和应用，拼宽桥梁连接装置包括旧桥梁翼缘板，还包括新桥梁翼缘板、过渡搭板和沥青混凝土桥面；新桥梁翼缘板和旧桥梁翼缘板的上端面均设置有台口，台口的内侧壁高度低于外侧壁高度；新桥梁翼缘板和旧桥梁翼缘板通过若干过渡搭板搭接，过渡搭板设置在新桥梁翼缘板的台口和旧桥梁翼缘板的台口内，若干过渡搭板的底部与台口的底部之间设置有垫层，过渡搭板的两侧分别与新桥梁翼缘板的台口外侧壁、旧桥梁翼缘板的台口外侧壁之间形成间隙，该间隙内设置有形变缓冲层；沥青混凝土桥面铺设在过渡搭板、新桥梁翼缘板和旧桥梁翼缘板的上端面。本发明解决了现有连接方式易导致拼宽桥梁的桥面开裂的问题。
