High-temperature steam curing construction method for prefabricated bridge deck of UHPC steel-concrete composite beam without coarse aggregate
The invention provides a high-temperature steam curing construction method for a prefabricated bridge deck of a UHPC steel-concrete composite beam without coarse aggregate. The method comprises the following steps that 10, steel bars are blanked and machined, specifically, the steel bars are machined and distributed in a centralized mode in a factory; 20, a mold is installed, specifically, a formwork of the bridge deck is installed, and the formwork comprises a bottom mold, a transverse side mold and a longitudinal side mold; 30, the steel bars and embedded parts are installed, specifically, an upper layer of steel bar net and a lower layer of steel bar net which are arranged in a spaced mode are installed on the formwork through the steel bars, and the embedded parts are installed on the formwork; and 40, concrete is mixed, specifically, a premix package with the concrete prefabricated and an additive and steel fiber formula package are included, and the premix package and the formula package are put into a stirrer till the concrete is mixed and discharged out of a station. According to the high-temperature steam curing construction method for the prefabricated bridge deck of the UHPC steel-concrete composite beam without the coarse aggregate, the self-weight load of the structure can be reduced, the design is lighter and more economical, and the common problem of cracking of the bridge deck and the like can be well solved.
一种无粗骨料UHPC钢混组合梁预制桥面板高温蒸养施工方法，包括以下步骤：步骤10，钢筋下料及加工，包括钢筋由厂内集中加工、配送；步骤20，模具安装，包括安装桥面板的模板，模板包括底模、横向侧模和纵向侧模；步骤30，钢筋及预埋件安装，包括采用所述钢筋在所述模板上安装上下两层间隔设置的钢筋网，在所述模板上安装预埋件；步骤40，混凝土拌合，包括预制有混凝土的预混料包装以及外加剂和钢纤维配方包装，在搅拌机中投入所述预混料包装和配方包装直到混凝土拌合出站。本发明无粗骨料UHPC钢混组合梁预制桥面板高温蒸养施工方法，不仅可以降低结构自重荷载，使设计更加轻巧经济，并且可以很好的解决桥面板开裂等通病问题。
