Concrete bridge deck widening structure with steel joists
A concrete bridge deck widening structure with a steel joist is formed through the following steps that S1, firstly, an original concrete beam wing plate is chiseled away, steel bars are planted in the exposed design positions of the wing plate, and holes are drilled in the design positions, corresponding to connecting anchor bolts, of an original concrete beam web and a lower wing plate; s2, steel bars are laid and welded to exposed transverse steel bars of the original concrete beam, a steel bar net is formed, and then a side die and a bottom die are vertically arranged; s3, an ultra-high performance cement-based composite material layer is poured, covered and cured; s4, steel guardrails are installed; the structure involved in the process is simple in construction, clear in stress, convenient to construct, short in period and small in influence on traffic. The widened structure is good in integrity, economical and attractive, and the problems that an existing widening method is high in manufacturing cost, complex in construction, unstable in connection between a widened part and an original structure, poor in integrity and the like can be solved.
一种带钢托梁的混凝土桥面板拓宽结构，该结构的形成包括以下步骤：S1、首先对原混凝土梁翼板凿除处理，在翼板露出的设计部位进行植筋，并在原混凝土梁腹板和下翼板对应连接锚栓的设计位置处钻孔；S2、铺设钢筋，与原混凝土梁露出的横向钢筋焊接，形成钢筋网，随后立设侧模及底模；S3、浇筑超高性能水泥基复合材料层，并覆盖养生；S4、安装钢护栏；该工艺所涉及的结构构造简单、受力明确、施工方便且周期短、对交通影响较小。拓宽后的结构整体性好、经济、美观，可解决现有拓宽方法存在的造价高、施工繁琐、拓宽部分与原结构衔接不稳定，整体性较差等问题。
