钢-混组合梁顶板钢筋砼高空悬臂浇筑施工方法
摘要：
本发明公开了一种钢-混组合梁顶板钢筋砼高空悬臂浇筑施工方法，包括a）首先进行翼板三角架及翼板模板的安装；（b）通过以翼板模板作为工作平台，开展箱室内支撑系和箱室模板的安装（；c）之后进行箱间支撑系和箱间模板的安装；d）钢梁顶板钢筋安装；（e）钢梁顶板钢筋混凝土浇筑；（f）钢梁顶板预应力系统张拉；（g）张拉完成后压浆封锚并进行钢梁的墩梁固结施工；（h）钢梁顶板模板拆除。本发明克服以往顶板砼施工过程中模板高度不易调节，以及箱室内模板拆除时的光线不足等问题，提供一种具备方便调节模板的高度，并能提供箱室内模板拆除时所需的光线以及提高工作效率等优点的施工方法。
摘要（英）：

The invention discloses a steel-concrete combination beam based roof reinforced concrete high-altitude cast-in-cantilever construction method. The method includes: a) mounting wing plate triangular frames and wing plate formworks; (b) taking the wing plate formworks as operation platforms to mount chamber internal supporting systems and chamber formworks; (c) mounting inter-chamber supporting systems and inter-chamber formworks; (d) mounting steel beam roof rebars; (e) concreting the steel beam roof rebars; (f) tensioning a steel beam roof prestress system; (g) after tensioning is finished, performing grout squeezing, anchor sealing and pier beam consolidation of steel beams; (h) demounting steel beam roof formworks. The construction method has advantages that problems of difficulty in formwork height adjustment, light insufficiency in removal of chamber internal formworks in a roof concrete construction process are solved, and convenience in formwork height adjustment, light sufficiency in removal of chamber internal formworks, improvement of operation efficiency and the like are realized.
