预制装配式混凝土住宅的土建增量成本分析

Analysis of Civil Engineering Incremental Cost of Precast Concrete Housings

以杭州市某预制装配式混凝土保障性住房工程为研究对象,根据调研数据,分析采用预制外墙、预制梁、预制楼板、预制楼梯和预制阳台板后相比现浇体系的单位建筑面积增量成本。此外还计算预制装配体系与现浇体系在一些施工综合措施方面的成本差。根据以上分析结果,进一步分析预制率为30%和40%时的土建综合增量成本,为进行预制装配式住宅建设的相关企业进行土建成本分析提供参考。

Taking precast concrete indemnificatory housing project in Hangzhou as the research object,this paper analyzes the incremental cost per building area of precast facade wall,beam,f loor,stairs,and balcony panel are calculated separately compared to the cast-in-place system according to the investigation data.In addition,calculates cost difference between precast system and cast-in-place system in some general constructional measures.Based on the above results,analyzes the comprehensive incremental cost in case of precast ratio 30% and 40%,in order to provide reference for the relative constructional enterprises of precast concrete housing to carry out civil engineering cost analysis.
