Vase pier bridge structure
The invention relates to the technical field of bridges, and particularly discloses a vase pier bridge structure which comprises a cross beam and a vase pier body and further comprises inclined supports arranged between the cross beam and the vase pier body, and the inclined supports are symmetrically arranged at the two ends of the upper edge of the vase pier body in the transverse bridge direction. An included angle formed by the axis of the inclined support and the axis of the vase pier body is theta; the vase pier body is further provided with a stop block mechanism playing a limiting role in the transverse bridge direction. Wherein theta is less than or equal to 25 degrees. The direction of the vertical force of the support is changed through the inclined support, so that the stress state of the vase pier can be greatly improved, pull rod steel bars and inclined ribs on the upper edge of the pier top can be omitted, and the thickness of the pier is optimized; the number of the stop block mechanisms is optimized, and the stop block mechanisms not only play a role in preventing beam falling under the action of an earthquake, but also completely replace the function of a transverse limiting support in a normal use state, so that the transverse limiting support of a full bridge is omitted, and the construction cost and the construction difficulty are reduced.
本发明涉及桥梁技术领域，具体公开了一种花瓶墩桥梁结构，包括横梁和花瓶墩本体，还包括设于横梁和花瓶墩本体之间的斜向支座，斜向支座沿横桥向对称设置于花瓶墩本体的上缘两端，斜向支座的轴线与花瓶墩本体的轴线所形成的夹角为θ；花瓶墩本体上还设有在横桥向起到限位作用的挡块机构；其中，θ≤25°。本发明利用斜向支座改变支座竖向力的方向，从而可以极大地改善花瓶墩受力状态，由此可以取消墩顶上缘的拉杆钢筋和斜筋，优化桥墩厚度；优化挡块机构的数量，挡块机构不仅在地震作用下起到了防落梁作用，同时在正常使用状态下完全取代横向限位支座的功能，从而取消全桥的横向限位支座，降低了工程造价和施工难度。
