钢筋桁架混凝土叠合板拆分设计研究

Research on Split Design of Reinforced Truss Concrete Composite Slab

因生产及运输条件限制,宽度较大的钢筋桁架混凝土叠合板需要拆分成两块或三块。拆分时,拆分节点形式和拆分宽度对钢筋含量以及生产、施工难易程度均有影响。本文对接缝节点形式进行比较分析,提出了接缝的选择原则,并分析拆分后板宽度对钢筋含量的影响,提出两拼桁架叠合板最优宽度的求解方法,为工程设计人员提供借鉴和参考。

Due to the production and transportation constraints,the reinforced truss concrete composite slab with large width should be divided into two or three.In the process of splitting,the form of splitting node and the width of splitting node have influence on the content of reinforcement and the degree of difficulty in production and construc⁃tion.In this paper,the joint joint forms were compared and analyzed,the joint selection principle was put forward,and the influence of the split plate width on the reinforcement content was analyzed,and the solution method of the optimal width of the composite plate of two-part truss was put forward,which could be used for reference by engineer⁃ing designers.
