Steel concrete beam bridge deck slab prefabricated construction method
The invention discloses a steel concrete beam bridge deck slab prefabricated construction method. The steel concrete beam bridge deck slab prefabricated construction method comprises the following steps that when a steel concrete beam bridge deck slab prefabricated site is overall hardened successfully and foundation concrete meets the pre-set design strength requirements, a prefabricated bridge deck slab moulding bed is started to be machined; a steel plate and a comb plate are adopted for side formwork construction, and side formworks are fixed to a bottom formwork in the mode of welding positioning rebars and positioning clamps; after the rebars are subjected to foundation treatment, rebar construction is conducted according to the design length of the exposed size of preburied rebars around prefabricated bridge deck slabs and the cross and staggering spacing of the rebars between the slabs; concrete construction is conducted, specifically, concrete pouring is conducted on the basisof inspecting formwork supports, formworks and the rebars; prefabricated slab concrete is subjected to manual roughening treatment and made into the concavo-convex rough surface; and covered sprinkling curing is conducted after final setting of the concrete. By adopting the steel concrete beam bridge deck slab prefabricated construction method, the construction efficiency and quality on the upperpart of a bridge can be improved, and waste of steel materials is greatly reduced.
本发明公开一种钢混梁桥面板预制施工方法，该方法包括以下步骤：在钢混梁桥面板预制场地整体硬化成且基础混凝土达到预设设计强度要求时，开始进行预制桥面板胎模的加工；采用钢板和梳子板进行侧模施工，并采用焊接定位钢筋及定位卡的方式将侧模固定在底模上；在对钢筋进行基础处理之后，根据预制桥面板周边预埋钢筋的外漏尺寸的设计长度和板间钢筋交叉错开的间距进行钢筋施工；混凝土施工，具体包括在对模板支架、模板和钢筋进行检查处理的基础上，进行混凝土浇筑；对预制板混凝土进行人工凿毛处理，做成凹凸的粗糙面；待混凝土终凝后进行覆盖洒水养护。采用本发明，可以提高桥梁上部的施工效率和质量，极大的减少对钢材的浪费。
