Vierendeel prestressed concrete continuous rigid frame bridge triangular area construction method
The invention relates to an open-web prestressed concrete continuous rigid frame bridge triangular area construction method, and belongs to the technical field of bridges, and the construction method comprises the following steps: S1, mounting an upper chord stiff skeleton and a lower chord stiff skeleton on a concrete pier column in a cantilever manner, the ends, away from the concrete pier column, of the upper chord stiff framework and the lower chord stiff framework are connected to form a triangular structure; and S2, concrete pouring formworks are suspended on the upper chord stiff framework and the lower chord stiff framework, and the upper chord stiff framework and the lower chord stiff framework form a triangular steel-concrete structure after concrete pouring. The stable and reliable triangular stiff framework is used as a bearing structure and a working platform for construction of the triangular area main beam, a formwork is erected, beam body concrete is poured, a floor stand or a temporary buckling and hanging system does not need to be erected, construction is flexible, and the method has the advantages of being safe and reliable in construction, few in procedure steps, easy and convenient to operate, high in quality assurance degree and capable of obviously saving investment. And the development and application of the bridge type can be greatly promoted.
本申请涉及一种空腹式预应力混凝土连续刚构桥三角区施工方法，属于桥梁技术领域，施工方法包括以下步骤：S1：在混凝土墩柱上悬挑安装上弦劲性骨架和下弦劲性骨架，将上弦劲性骨架和下弦劲性骨架远离混凝土墩柱的一端相互连接并形成三角形结构；S2：分别在上弦劲性骨架和下弦劲性骨架悬搭混凝土浇筑模板，上弦劲性骨架和下弦劲性骨架通过浇筑混凝土后形成三角形钢混结构。利用稳定可靠的三角形劲性骨架作为“三角区”主梁施工的承重结构和作业平台，立模板和浇筑梁体混凝土，不用搭设落地支架或设置临时扣挂系统，施工灵活，具有施工安全可靠、程序步骤少、操作简便易行，质量保证度高，投入明显节省的优点。可极大地促进该类桥型的发展和应用。
