Shaped turnover pushing steel guide beam for steel-concrete composite bridge
The invention discloses a shaped turnover pushing steel guide beam for a steel-concrete composite bridge, which comprises two parallel main beams and a connecting truss for connecting the two main beams, the line type of the bottom surface of each main beam is consistent with that of a steel box beam, and each main beam comprises a connecting section, a transition section and a standard section which are connected through a high-strength bolt; a groove connected with a steel box girder is formed in one end of the connecting section, and the transition section is a variable-cross-section steel plate girder which is gradually reduced from the connecting section to the standard section along the longitudinal height. The main beam is divided into the connecting sections, the transition sections and the standard sections, adaptation can be achieved by adjusting the number of the standard sections in the standard sections according to different span requirements, the grooves formed in the connecting sections serve as connecting points to adapt to different types of steel box girders, the contact face with the steel box girders can be increased so as to reduce the stress of connecting welding seams, and the welding quality of the steel box girders can be improved. And the bolt connecting structure is convenient to disassemble, assemble and reuse, and has the characteristics of convenience in disassembly and assembly, simplicity in turnover, high adaptability, stability, reliability and small deflection value.
本发明公开一种用于钢‑混组合桥梁的定型化可周转顶推钢导梁，包括两根相互平行的主梁、连接两根主梁的连接桁架，主梁底面线型与钢箱梁一致，主梁包括通过高强度螺栓连接的连接段、过渡段、标准节段，连接段一端设有与钢箱梁连接的凹槽，过渡段为沿纵向高度自连接段向标准节段逐渐减小的变截面钢板梁。本发明将主梁划分为连接段、过渡段、标准节段，可根据不同跨度要求通过调整标准节段内的标准节数量进行适应，而设置于连接段上的凹槽作为连接点即可适应不同的钢箱梁型号，且能增大与钢箱梁的接触面以减小连接焊缝的应力，而且螺栓连接结构也便于拆装重复使用，具有拆装方便、周转简单、适应性强、稳定可靠、挠度值小的特点。
