Simply-supported track beam bridge with continuous running surfaces and construction method
The invention discloses a simply-supported track beam bridge with a continuous walking face and a construction method, and is applied to the technical field of simply-supported track beam bridge design and construction.The simply-supported track beam bridge comprises a track beam erected on a pier, a rigid connection structure and an on-site prestressed assembly, and prefabricated prestressing tendons are pre-buried in the track beam; the adjacent track beams are connected through rigid connection structures, the top faces and the side faces of the rigid connection structures are correspondingly flush with the top faces and the side faces of the track beams respectively, and the rigid connection structures provide driving faces and supports for the walking wheels, the guide wheels and the stabilizing wheels to pass through the third structural joints. The construction method is a construction method of the simply-supported track beam bridge and comprises the steps of constructing the rigid connection structure and tensioning. According to the invention, the beam end corner and upwarp effect of the simply supported beam can be effectively reduced, the anti-seismic, anti-torsion, anti-roll, anti-fatigue and durable properties of the whole linked bridge are enhanced, smooth transition between two-span track beams is realized, and the construction difficulty is also reduced.
本发明公开了一种走行面连续的简支轨道梁桥及施工方法，其应用于简支轨道梁桥设计和施工技术领域，该简支轨道梁桥包括搭设在桥墩上的轨道梁、刚性刚接结构和现张预应力组件，轨道梁内预埋预制预应力束，相邻轨道梁之间通过刚性刚接结构连接，刚性连接结构的顶面、侧面与轨道梁的顶面、侧面分别对应平齐，并为走行轮、导向轮和稳定轮驶过第三结构缝提供行驶面和支撑，现张预应力组件包括设于轨道梁内的现张预应力束，施工方法为简支轨道梁桥的建造方法，包括施做刚性刚接结构和张拉过程；本发明能够有效降低简支梁的梁端转角和翘起效应，加强了整联桥的抗震、抗扭、抗侧倾、抗疲劳和耐久性能，实现两跨轨道梁间的平顺过渡，也减小了施工难度。
