Cast-in-place box girder support construction process
The invention discloses a cast-in-place box girder support construction process, and belongs to the field of bridge construction. The process comprises the following steps: S1, processing a foundation; S2, assembling a frame body; S3, mounting a formwork: arranging an adjustable bracket at the top end of a vertical rod, and arranging a plate supporting assembly and a bottom formwork on the adjustable bracket; S4, pre-pressing load: laying a plurality of pre-pressing pieces on the bottom formwork, and pre-pressing the frame body by the total weight of the pre-pressing pieces according to 120% of the self weight of the box girder; S5, adjusting the bottom formwork: after pre-pressing is completed, adjusting the elevation, the pre-camber and the transverse curve of the bottom formwork throughan adjustable bracket according to pre-pressing data; and S6, pouring the box girder: bonding and molding a box girder bottom plate and web steel bars on the formwork, and conducting concrete pouring. By means of the cast-in-place box girder support construction process, the cast-in-place box girder construction quality can be improved.
本发明公开了一种现浇箱梁支架施工工艺，属于桥梁建筑领域，该工艺包括的步骤有：S1.地基处理；S2.拼装架体；S3.模板安装，在立杆顶端设置可调托座，在可调托座上设置板支撑组件及底模板；S4.预压载荷，在底模板上铺设若干预压件，预压件的总重量按箱梁自重的120％对架体进行预压；S5.底模板调整，预压完成后，对底模板的标高、预拱度及横向曲线根据预压数据通过可调托座进行调整；S6.箱梁浇筑，将箱梁底板、腹板钢筋绑扎成型在模板上，进行混凝土浇筑，利用该现浇箱梁支架施工工艺，可以提高现浇箱梁施工的质量。
