Construction method of large-span reinforced concrete horizontal member
The invention relates to the technical field of constructional engineering, in particular to a large-span reinforced concrete horizontal member construction method which comprises the following steps that an early-dismantling supporting frame system and a late-dismantling supporting frame system are erected according to a drawing for designing a supporting system, and both the early-dismantling supporting frame system and the late-dismantling supporting frame system adopt disc buckle type scaffolds; the wall column pouring formwork, the beam pouring formwork and the floor pouring formwork are erected and poured in sequence; when the concrete strength of the wall column structure reaches 50% of the design strength, the wall column formwork is dismantled; when the concrete strength reaches 75% of the design strength, the early-dismantling supporting frame system and the formwork on the early-dismantling supporting frame system are dismantled; when the concrete strength reaches 100% of the design strength, the late-dismantled supporting frame system and the formwork on the late-dismantled supporting frame system are dismantled; according to the construction method, the structural span is manually reduced in the construction stage, the internal force of the structural span is reduced, the formwork can be demounted early, the safety degree of the structure is not affected, material turnover is accelerated, the cost is reduced, the work efficiency is improved, and the construction period is shortened.
本发明涉及建筑工程技术领域，一种大跨度钢筋混凝土水平构件施工方法，包括如下步骤：根据设计支撑体系的图纸搭设早拆支撑架体系和晚拆支撑架体系，早拆支撑架体系和晚拆支撑架体系均采用盘扣式脚手架；依次进行墙柱浇筑模板、梁浇筑模板和楼板浇筑模板支模及浇筑；墙柱结构混凝土强度达到设计强度的50％时，拆除墙柱模板；混凝土强度达到设计强度的75％时，拆除早拆支撑架体系及早拆支撑架体系上的模板；混凝土强度达到设计强度的100％时，拆除晚拆支撑架体系及晚拆支撑架体系上的模板；本施工方法通过在施工阶段把结构跨度人为的划小，降低其内力，使模板能够早拆，而结构的安全度又不受影响，以加快材料周转，降低成本，提高工效，缩短工期。
