Rigid frame bridge beam, construction method thereof and ultra-high-speed electromagnetic propulsion track beam formed by rigid frame bridge beam
The invention provides a rigid frame bridge beam, a construction method thereof and a super-high-speed electromagnetic propulsion track beam formed by the rigid frame bridge beam, and relates to the technical field of bridge engineering.The rigid frame bridge beam comprises a bearing platform, an anchoring beam body, a rigid frame bridge pier, a beam bottom protruding block, a support and a bridge pier, and the rigid frame bridge pier is arranged above one end of the bearing platform; the beam bottom protruding block is fixed to the bottom face of one end of the anchoring beam body, the rigid frame bridge pier is of a cast-in-place reinforced concrete structure allowing the beam bottom protruding block to be vertically embedded, and the bottom face of one end of the anchoring beam body is connected with the top face of one end of the bearing platform through the rigid frame bridge pier. By means of a stress structure formed by the rigid frame bridge pier and the beam bottom protruding block, anchoring force of steel rails at the two ends of the ultra-high-speed electromagnetic propulsion track beam can be borne, a support which is high in price and poor in durability is avoided, and high position and size precision is achieved.
本发明提供了刚构桥梁及其施工方法、构成的超高速电磁推进轨道梁，涉及桥梁工程技术领域，包括本申请提供了一种刚构桥梁，包括：承台、锚固梁体、刚构桥墩、梁底凸块、支座和桥墩，所述刚构桥墩设置在所述承台一端的上方，所述梁底凸块固定于所述锚固梁体一端的底面，所述刚构桥墩为供所述梁底凸块竖向嵌入的现浇钢筋混凝土结构，所述锚固梁体一端的底面与所述承台一端的顶面通过所述刚构桥墩连接，所述梁底凸块与所述承台一端的顶面通过所述刚构桥墩连接，本发明通过刚构桥墩和梁底凸块构成的受力结构，能够承担超高速电磁推进轨道梁两端钢轨的锚固力，避免了采用价格昂贵、耐久性差的支座，具备较高的位置及尺寸精度。
