商品混凝土浇筑杯口基础方案的探讨

Discussion on Cup Foundation Casting of Commercial Concrete

根据商品混凝土塌落度大、流动性增强,导致杯口基础浇筑困难的现状,分析设计构造要求,提出留置施工缝,杯壁混凝土二次浇筑的方案,计算杯壁竖向配筋及抗剪键面积,补强设计杯壁结合面施工缝。

Commercial concrete has big slump consistency and increased flowing property, which results in difficulty of cup foundation casting. This article analyses the design requirements and construction means of cup foundation, and proposes method of reserving construction seam and second casting of cup foundation. Vertical bar of cup wall and area of shear pin are calculated for reference of similar structure design.
