摘要
以广西柳州装配式建筑现代化产业园的倒班楼及配套设施工程为例,结合装配式混凝土框架结构梁板柱现浇节点的施工特点,通过模板类型比选、研发、实施及改进等技术措施,最终自主设计采用了外穿孔式铝合金模板。因该种模板能紧贴PC构件表面,故利用PC构件预留孔并采用螺杆加固即可完成装模。模板拼缝严密,强度高,拼装施工简单方便,浇筑后可满足免抹灰清水混凝土成形质量要求,在类似工程中具有一定的推广价值。
Taking the shift building and its supporting facilities project of the prefabricated building modernization industrial park in Liuzhou,Guangxi as an example,combined with the construction characteristics of cast-in-place joints of prefabricated concrete frame structure beams,slabs,and columns,through the formwork type comparison,research and development,implementation and improvement of other technical measures,the self-designed externally perforated type of aluminum alloy formwork was finally designed and used.Because this kind of formwork can closely cling to the surface of PC component,it can be installed by using reserved holes in PC components and strengthened by using screws.The joint of the formwork is tight,the strength is high,and the assembly construction is simple and convenient.After pouring,it can meet the forming quality requirement of plastering-free fair-faced concrete,which has certain promotion value in similar projects.
