Prefabricated concrete anti-collision guardrail mounting and positioning device and construction method
The invention provides a prefabricated concrete anti-collision guardrail mounting and positioning device and a construction method, and relates to the field of bridge construction. The bridge deck structure comprises a guardrail body and a bridge deck, at least one pair of metal corrugated pipes extending in the vertical direction is embedded in the guardrail body, the metal corrugated pipes penetrate through the upper side and the lower side of the guardrail body, and L-shaped connecting steel bars are embedded in the bridge deck. The vertical ends of the connecting steel bars extend out of the top of the bridge deck slab and are inserted into the metal corrugated pipes, and concrete is poured into the metal corrugated pipes. Angle steel is embedded in the bottom of the guardrail body, a steel plate is embedded in the top of the bridge deck slab, and one side of the angle steel is welded to the top of the steel plate. The bridge deck guardrail has the effects that the installation firmness between the guardrail body and the bridge deck can be improved, and labor consumption is reduced.
本申请提供了一种预制混凝土防撞护栏安装定位装置及施工方法，涉及桥梁施工领域。其包括护栏本体和桥面板，所述护栏本体的内部预埋有至少一对沿竖直方向延伸的金属波纹管，所述金属波纹管贯穿所述护栏本体的上侧和下侧，所述桥面板内预埋有L形的连接钢筋，所述连接钢筋的竖端从桥面板的顶部伸出且插入到金属波纹管内，所述金属波纹管内浇注有混凝土；所述护栏本体的底部预埋有角钢，所述桥面板的顶部预埋有钢板，所述角钢的一侧焊接在钢板的顶部。本申请具有能够提高护栏本体与桥面板之间安装牢固性并降低劳动力消耗的效果。
