主要介绍了格构钢筋在预制装配式混凝土结构中的发展及应用,对格构钢筋的结构性能、叠合楼板临时支撑以及浇筑混凝土后格构钢筋在叠合楼板水平接缝和竖向拼缝处的作用进行了分析,并着重介绍了利用格构钢筋开发的新型Bubble板体系在应用于大跨度结构时突出的结构优势和经济性。格构钢筋在国外的发展历程反映了其应用的多样性,基于国外对叠合楼板标准化临时支撑体系以及水平接缝、竖向拼缝处楼板的性能研究介绍了叠合楼板的设计方式和注意要点,供以后的应用与研究借鉴和参考。
This paper mainly introduces the development and application of lattice reinforcement in prefabricated concrete structures. The structural performance of lattice reinforcement, the temporary support of composite slab and the horizontal joints and vertical joints The paper analyzes the function of the new Bubble board system which is developed by the use of lattice steel bars and highlights the structural advantages and economy when applied to the long-span structure. The development course of the lattice steel in foreign countries reflects the diversity of its application. Based on the overseas research on the performance of the standard temporary supporting system of laminated slabs and the horizontal seams and the vertical joints, the design method and attention of the laminated slab are introduced Points for future application and research for reference and reference.
