发展预应力混凝土结构与工艺,是为了使现代的多层工业与民用建筑具有空间大、布置灵活,并具有良好的抗震性能,同时为了改革现浇结构的楼面模板,我们提出了一种后张预应力框架与预应力叠合楼板相结合的现浇框架结构体系,选择某机电楼工程进行试点。该工程的主体结构已于1982年12月建成,现将其施工情况介绍如下。 The development of prestressed concrete structures and processes is to make modern multi-layer industrial and civil buildings have a large space, flexible layout, and good seismic performance. At the same time, in order to reform the floor stencils of cast-in-situ structures, we propose a A cast-in-place frame structure system combining a prestressed frame and a prestressed laminated floor slab was selected to conduct a pilot project for an electromechanical building project. The main structure of the project was completed in December 1982 and its construction is now described as follows.
