New and old bridge splicing prefabricated tough structure for bridge widening and construction method of new and old bridge splicing prefabricated tough structure
The invention provides a new and old bridge splicing prefabricated tough structure for bridge widening and a construction method thereof, and belongs to the technical field of bridge engineering. In the structure provided by the invention, the new bridge cover beam shockproof stop block comprises the first clamping block and the second clamping block, the cross-shaped section beam comprises the web plate and the wing plate, the wing plate divides the web plate into the first plate body and the second plate body, the first plate body is clamped between the old bridge edge beam and the new bridge edge beam, and the second plate body is clamped between the old bridge edge beam and the new bridge edge beam. The two wing plates are in lap joint below the old bridge edge beam and the new bridge edge beam correspondingly and are fixed to the old bridge edge beam and the new bridge edge beam, the two ends, in the length direction, of the cross-shaped section beam are borne on the two H-shaped section beams correspondingly, and the two ends of the second plate body are arranged in the beam containing grooves; and the H-shaped section beam is clamped on the first clamping block through the clamping groove. The defects that in the prior art, additional stress at the connecting position is large, and the construction technology is complex can be effectively overcome, and the construction period can be shortened through the prefabricated structural form.
本申请提供一种桥梁加宽用新旧桥梁拼接预制韧性结构及其施工方法，属于桥梁工程技术领域。本申请提供的结构中，新桥梁盖梁防震挡块包括第一卡块和第二卡块，十字型截面梁包括腹板及翼板，翼板将腹板分隔形成第一板体和第二板体，第一板体夹设于旧桥梁边梁和新桥梁边梁之间，两个翼板分别搭接在旧桥梁边梁和新桥梁边梁下方，并与旧桥梁边梁和新桥梁边梁固定，十字型截面梁沿长度方向的两端分别承载于两个H型截面梁上，且第二板体的两端置于置梁槽内；所述H型截面梁通过卡接槽卡接在第一卡块上。本申请可有效解决现有技术中连接位置附加应力较大、施工工艺复杂等缺陷，预制的结构形式还可缩短施工周期。
