某预制装配式结构施工技术分析

Analysis on construction technique for a prefabricated structure

介绍某装配式结构工程概况以及施工组织中的预制构件深化设计方法和要点,给出了标准层施工工期计划和临边防护措施。结合具体的工程实例,介绍了装配式施工过程中所涉及构件运输与堆放、进场验收、套筒连接、钢筋定位控制,并对吊装过程中的质量、安全控制等关键性的施工技术和具体措施做了详细的阐述。最后对雨季吊装施工和冬季灌浆施工的要点做了详细说明,以期能为类似的预制装配式建筑施工提供参考借鉴。

The general situation of a prefabricated structure project and the deepened design method of prefabricated component was introduced. In addition,the construction plan of standard layer and the border protection measures were given. Combined with a specific engineering project,the key technologies in the process of prefabricated building’ s construction such as transportation and stacking,approaching acceptance,the positioning and sleeve grouting connection of steel bars,and the quality and safety control measures in the lifting process were introduced in detail. Finally,the main points of lifiting construction in rainy season and grouting construction in winter were explained,providing reference for similar prefabricated building construction.
