现浇箱梁就是在桥位上搭设满堂支架,在支架上浇筑混凝土,混凝土达到强度预应力张拉后拆除模板、支架。现浇法施工,对于现浇箱梁整个梁体的钢筋可不中断,桥梁的整体刚度好,并避免了预制安装形成的接缝以及梁体的颜色的差异,整体色泽效果好。缺点是:前期准备时间长,施工中要占大量的支架和模板,施工费用一次投入大,下面就碗扣式支架作为满堂支架浇注箱梁的施工工艺和自检工作要点简述如下。
Cast-in-place box girder is erected in the bridge position full support, pouring concrete in the stent, the concrete reaches the strength of the prestressed tension removal template, stent. Cast-in-place construction of steel beams for the whole cast-in-place box girder without interruption, the overall stiffness of the bridge is good, and to avoid the prefabricated seam and the formation of the joints of the color difference, the overall color effect. Drawbacks are: long preparation time, the construction to account for a large number of stents and templates, construction costs once invested, the following on the bowl button bracket as a full stent pouring box girder construction process and self-test work briefly as follows.
