预应力混凝土钢管桁架叠合板施工关键技术研究

Research on key construction technology of prestressed concrete pipe truss composite slab

预应力钢管桁架混凝土叠合板作为一种新型的叠合板,结合了钢筋桁架混凝土叠合板与预应力混凝土叠合板的优点,有效避免了传统叠合楼板开裂、反拱和成本偏高等问题。为了解决装配式叠合板在实际工程应用中的技术及管理问题,本文通过其在山西建筑产业现代化(晋中)园区一期项目中的应用,通过其在装配式钢框架结构施工应用中的重难点及关键技术,对叠合楼板的吊装困难、支撑体系复杂及梁板连接薄弱等问题进行了总结分析,以现有理论为基础,提出了解决办法,并在实践中应用,验证了其可行性,同时结合BIM技术对施工管理提出了管理办法,为同类工程后续施工提供了一定的技术支持及经验参考。结果显示,此新型叠合板的应用有效地避免了传统叠合板存在的问题,为装配式建筑的发展提供了助力。

Prestressed concrete pipe truss composite slab is a new type of composite slab,it combines the advantages of reinforced truss concrete composite slab and prestressed concrete composite slab,it effectively avoids the problems of traditional composite slab cracking,anti-arch and high cost and so on.This article through its application in Shanxi construction industry modernization(Jinzhong)Park project,summarized its difficult point and key technologies in the application of Prefabricated rigid frame construction,analyzed The problems such as the difficulty of lifting the composite slab,the complexity of the support system and the weak connection between the beam and slab,put forward the solution,and combined with the application of BIM technology in it,provides some technical support and experience reference for the follow-up construction of similar projects.
