摘要
提出了一种后张法预应力框架与钢次梁组合装配式物流库结构体系,并基于河北廊坊某物流园项目,介绍了该体系的结构布置,阐述了梁柱节点、预应力张拉节点、主次梁节点、组合钢次梁节点的设计要点,提供了一整套技术解决方案.对比该体系与现浇混凝土框架结构的工期与造价得到,相对于现浇混凝土框架结构,该体系能够减少工期并降低造价.
Abstract
A post-tensioned prestressed frame and steel secondary beam combined prefabricated logistics warehouse structure system was proposed.Based on a logistics park project in Langfang,Hebei province,the structural layout of the system was introduced.The design points of beam-column joints,prestressed tension joints,main and secondary beam joints,and composite steel secondary beams were also introduced,and a complete set of technical solutions was provided.Comparing the construction period and cost of the system with the cast-in-place concrete frame structure,it is concluded that the system can reduce the construction period and reduce the cost.
