Triangular area construction method of open-web rigid frame bridge
The invention relates to the technical field of open-web rigid frame bridge construction, and discloses a triangular area construction method of an open-web rigid frame bridge, which comprises the following steps: mounting a lower chord starting section bracket at the top of a concrete pier column, pouring a 0th lower chord section, and dismounting the lower chord starting section bracket after the 0th lower chord section reaches self-stabilizing strength; pouring the lower chord sections symmetrically to the two sides in sequence, and meanwhile heightening the concrete pier column on the upper surface of the 0th lower chord section; heightening the concrete pier column to a designed height, mounting an upper chord starting section bracket at the top of the concrete pier column, pouring a 0th upper chord section, and dismounting the upper chord starting section bracket after the 0th upper chord section reaches self-stabilizing strength; pouring the upper chord sections symmetrically to the two sides in sequence; and when the nth lower chord section and the nth upper chord section are poured, performing closing, and forming a triangular area. According to the triangular area construction method, the upper chord and the lower chord are independently and separately constructed and do not interfere with each other, triangular area stress is simple, construction difficulty is small, and construction efficiency is high.
本申请涉及空腹式刚构桥施工技术领域，公开了一种空腹式刚构桥的三角区施工方法，包含步骤：在混凝土墩柱顶部安装下弦起始段支架，浇筑第0号下弦节段，待第0号下弦节段达到自稳强度后，拆除下弦起始段支架；向两侧依次对称浇筑下弦节段，同时，在第0号下弦节段上表面加高混凝土墩柱；混凝土墩柱加高至设计高度，在其顶部安装上弦起始段支架，并浇筑第0号上弦节段，待第0号上弦节段达到自稳强度后，拆除上弦起始段支架；向两侧依次对称浇筑上弦节段；在浇筑第n号下弦节段和第n号上弦节段时，进行合拢，形成三角区。本申请的三角区施工方法，上下弦独立分开施工，互不干扰，三角区受力简单，施工难度小，施工效率高。
