成都建工预筑科技研发中心装配式结构设计

Design of assembly structure in Chengdu Construction Engineering Pre-built Technology R&D Center

成都建工预筑科技研发中心采用装配整体式框架结构,装配率93%。结合十三五国家重点研发计划研究成果,以项目为例阐述了框架梁柱节点、密拼空心叠合板、双T板、外墙挂板节点等设计细节,为同类项目提供参考和借鉴。其中梁柱节点采取了一系列的措施,在满足承载力前提下,充分考虑节点区钢筋布置方式,方便预制构件制作和安装;密拼空心叠合板和双T板的应用,避免了后浇带整体式接缝的钢筋桁架叠合板制作安装困难、支撑多、造价高等缺点;外挂墙板节点不仅能满足承载力要求,而且能适应主体结构变形,安装方便。

Chengdu Construction Engineering Pre-built Technology R&D Center adopts an integrated frame structure system, the assembly rate is 93%. Combined with the research results of 13 th Five-Year National Key R&D Plan, the project was used as an example to illustrate the design details of frame beam-column joints, hollow close-fitting composite slabs, double T slabs and external panel joints, providing reference for similar projects. Among them, a series of measures have been adopted for the beam-column joints. Under the premise of satisfying the bearing capacity, the arrangement of steel bars in the joint area is fully considered to facilitate the production and installation of prefabricated components;the application of hollow close-fitting composite slab and double T slab avoids post-casting belts Integral joint reinforced truss composite panels have disadvantages such as difficult production and installation, multiple supports, and high cost;external panel joints can not only meet the requirements of bearing capacity, but also adapt to the deformation of the main structure and are easy to install.
