Variable cross-section bearing beam for bridge incremental launching construction
The invention discloses a variable cross-section bearing beam for bridge incremental launching construction. A beam body of a bridge is a steel channel beam, and incremental launching equipment is arranged at the pier top of a pier; the upper part of the variable cross-section bearing beam is connected with a beam bottom plate, and the lower part is connected with pushing equipment; the variable cross-section bearing beam is of a steel structure and comprises ship-shaped beams connected through connecting beams, and the two ends of each ship-shaped beam extend outwards to form cantilever arms.In the pushing construction, by arranging the variable cross-section bearing beam, the pushing force of the pushing equipment can be uniformly distributed on the beam bottom plate of the steel channel beam, so that the deformation or penetration of the beam bottom plate due to overlarge local stress is avoided, and the risk of overturning of the beam body can also be reduced.
本发明公开了一种桥梁顶推施工用变截面承载梁，所述桥梁的梁体为钢槽梁，桥墩的墩顶设有顶推设备；所述变截面承载梁上部承接梁底板，下部承接顶推设备；所述变截面承载梁为钢结构，包括通过连接梁连接的船型梁，所述船型梁两端向外延伸形成挑臂。在顶推施工中，通过设置上述变截面承载梁，可使顶推设备的顶推力均匀地分布在钢槽梁的梁底板上，避免梁底板因局部受力过大而变形或穿透，而且还能降低梁体倾覆的风险。
