Construction method for large-span special-shaped cast-in-place reinforced concrete vierendeel truss
The invention discloses a construction method for a large-span special-shaped cast-in-place reinforced concrete vierendeel truss to solve the technical problems that as for a special-shaped cast-in-place reinforced concrete vierendeel truss structure, the construction efficiency is low, and the construction quality is difficult to guarantee. The construction method comprises the following steps: (1) supporting system setting-up; (2) lower string beam formwork erecting, lower string beam steel bar binding and lower string beam concrete pouring; and (3) upper string beam, vertical column and floor formwork erecting, steel bar binding and concrete pouring. A concrete construction process of 'two times of formwork erecting and two times of pouring' is adopted, the construction quality of the cast-in-place reinforced concrete vierendeel truss is guaranteed, the construction efficiency and the engineering quality are effectively improved, and good economic and social benefits are obtained.
本发明公开了一种大跨度异形现浇钢筋混凝土空腹桁架施工方法，以解决异形现浇钢筋混凝土空腹桁架结构施工效率低、施工质量难以保障的技术问题。其包括以下步骤：（1）支撑体系搭设；（2）下弦梁模板支设、下弦梁钢筋绑扎、下弦梁混凝土浇筑；（3）上弦梁、立柱及楼板模板支设、钢筋绑扎、混凝土浇筑。本发明采用“两次支模，两次浇筑”混凝土的施工工艺，确保了现浇混凝土空腹桁架的施工质量，有效提高了施工效率和工程质量，取得了良好的经济和社会效益。
