后张无粘结预应力平板结构体系是近几年来迅速发展起来的一种新型楼盖体系。它具有整体性能好、空间大、可降低层高等优点。为进一步开发这项技术、充分发挥平板结构优越性,北京工业设计研究院、北京市第六建筑工程公司、北京市建筑工程研究所等单位提出了一种新的建筑结构体系——预应力板墙体系,并在北京永安公寓工程中应用。这种建筑体系综合预应力平板和大模板施工方法等长处,并在建筑上和结构上创造性地作了处理。一、概况永安公寓工程楼盖分三段,中段为多跨连续板,两端为简支,板跨7.2m,板厚16
The post-tensioned non-bonded prestressed flat structure system is a new type of floor system that has been rapidly developed in recent years. It has the advantages of good overall performance, large space, and lower layers. In order to further develop this technology and give full play to the superiority of the flat panel structure, Beijing Industrial Design Research Institute, Beijing No. 6 Construction Engineering Company, Beijing Institute of Architectural Engineering and other units proposed a new building structural system - prestressed panels. Wall system and application in Beijing Yongan Apartment Project. This kind of building system integrates the advantages of prestressed flat plates and large formwork construction methods, and creatively deals with the construction and structure. I. Overview Yong’an apartment building is divided into three sections. The middle section is a multi-span continuous plate. The two ends are simply supported. The span is 7.2m and the plate thickness is 16.
