Construction method of suspended large-span reinforced concrete conversion truss girder
The invention discloses a construction method of a suspended large-span reinforced concrete conversion truss girder. The construction method comprises the following steps of pouring concrete of shear walls on two sides to delta 10.00; erecting a high-formwork bent frame and installing a bottom formwork of a lower chord beam; binding the lower chord beam and shear wall steel bars; sealing side formworks of the lower chord beam; sealing the formwork of the shear walls; inserting joint bar in inclined web columns and beam upper columns; pouring the lower chord beam and shear wall concrete; curing; butt welding and binding inclined web columns and beam upper column steel bars; sealing the column formwork ; pouring column concrete; curing; installing the bottom formwork of the upper chord beam; binding the upper chord beam and shear wall steel bar; sealing the side formwork of the upper chord beam; sealing the formwork of the shear wall; inserting joint bar in the beam upper columns; pouring the upper chord beam and the shear wall concrete and curing. The construction method is shorter in construction period, safe, reliable, lower in cost and convenient to construct.
本发明公开了一种悬空大跨度钢筋砼转换桁架梁施工方法，包括下列步骤：浇筑两侧剪力墙砼至▽10.00→搭设高支模排架，安装下弦梁底模→绑扎下弦梁、剪力墙钢筋→下弦梁封侧模，剪力墙封模→斜腹柱、梁上柱插筋→浇筑下弦梁、剪力墙砼→养护→斜腹柱、梁上柱钢筋对焊、绑扎→封柱模→浇筑柱砼→养护→安装上弦梁底模→绑扎上弦梁、剪力墙钢筋→上弦梁封侧模，剪力墙封模→梁上柱插筋→浇筑上弦梁、剪力墙砼→养护。本发明工期较短、安全可靠、成本较低、施工方便。
