Straddle type monorail steel-concrete combined track beam and erecting method
The invention provides a straddle type monorail steel-concrete combined track beam and an erecting method, and relates to the technical field of track traffic, the straddle type monorail steel-concrete combined track beam comprises a steel beam, a reinforcing mesh and a concrete body, the top face of the steel beam is parallel to the ground, at least one set of shear nails are arranged on the top face of the steel beam, and each set of shear nails are arranged in the length direction of the steel beam; the reinforcing mesh is located above the shear nails, and the end of the reinforcing mesh is connected with the steel beams. And the concrete body is connected with the steel beam through the shear nails and the reinforcing mesh. The mode that the reinforcing mesh and the steel beam are directly connected and the mode that the concrete body is directly poured on the framework formed by the reinforcing mesh are adopted, so that a concentric-square-shaped stirrup used in the prior art is replaced, and the connection stability of the concrete body and the steel beam is improved; the construction step that in the prior art, double steel bars with the diameter phi being 25 mm and the distance being 100 mm need to be arranged in a cast-in-place section is omitted, the pouring difficulty is lowered, and meanwhile the phenomenon that in the prior art, cracks are likely to occur in the cast-in-place section is avoided.
本发明提供了一种跨座式单轨钢‑混结合轨道梁以及架设方法，涉及轨道交通技术领域，包括钢梁、钢筋网和混凝土体，钢梁的顶面平行于地面设置，钢梁的顶面设有至少一组剪力钉，每组剪力钉沿着钢梁长度方向布设；钢筋网位于剪力钉上方，钢筋网的端部与钢梁连接；以及，混凝土体通过剪力钉和钢筋网与钢梁连接。本发明通过将钢筋网与钢梁直接连接的方式，并且混凝土体通过直接浇筑在钢筋网构成骨架上的方式，替代了现有技术中使用回字型箍筋，增加混凝土体与钢梁的连接稳定性，同时，减少了现有技术需要在现浇段中配置双支直径φ25mm、间距100mm的钢筋施工步骤，降低浇筑难度的同时亦使得现有技术中避免现浇筑段易出现裂缝的现象。
