Beam seam structure between fabricated beam bridges, fabricated beam bridge and construction method
The invention belongs to the technical field of bridge floor continuous simply supported beam bridge design and construction, and particularly relates to a beam seam structure between fabricated beam bridges, a fabricated beam bridge and a construction method. The beam joint structure comprises a bridge floor simply supported beam type structure and a neutral shaft rigid connection structure from top to bottom; the neutral axis rigid connection structure is located at the neutral axis of the beam end section and is in rigid connection with the main beams on the two sides, the upper and lower edge tensile strain of the neutral axis rigid connection structure is reduced by more than ten times compared with a bridge deck continuous structure in the prior art under the action of a beam end corner, and cracks are basically avoided. The simply supported beam type structure of the bridge floor is simply supported on the wing plates on the two sides, and the top surface of the simply supported beam type structure does not generate cracks and is directly impacted by wheels, so that the phenomenon of frequent damage of pavement at the continuous position of the bridge floor in the prior art is effectively avoided; meanwhile, through the ingenious design of a plurality of inclined planes and pipelines in the drainage system, water flow avoids all tension cracking areas when passing through the concrete structure, and therefore the waterproofness of the bridge deck continuous structure is obviously higher than that of a bridge deck continuous structure in the prior art.
本发明属于桥面连续简支梁桥设计和施工技术领域，具体涉及一种装配式梁桥间的梁缝构造、装配式梁桥及施工方法。本发明的梁缝构造自上而下包括桥面简支梁式结构和中性轴刚接结构；中性轴刚接结构位于梁端截面中性轴处并与两侧主梁刚接，在梁端转角作用下中性轴刚接结构的上下缘拉应变相比现有技术的桥面连续结构降低数十倍以上，基本不会产生裂缝；而桥面简支梁式结构简支于两侧翼板之上，简支梁式结构顶面不会产生裂缝并直接受车轮冲击，有效避免了现有技术中桥面连续处的铺装频繁破损现象；同时，通过排水系统中多个斜面和管道的巧妙设计，水流经过混凝土结构时均避开了各处的受拉开裂区，故本发明的防水性显著高于现有技术的桥面连续结构。
