Prestressed concrete haunched beam slab floor structure
The invention discloses a prestressed concrete haunched beam slab floor system structure which comprises a plurality of frame columns distributed in a rectangular column net mode, continuous frame beams arranged in the longitudinal and transverse directions of the rectangular column net and floor slabs arranged between the frame beams, vertical haunches are arranged at the beam ends of the frame beams, and vertical haunches are arranged at the positions of floor slab supports. According to the floor system structure, a beam-slab structure system is adopted, the structural ductility is good, and the reliability is high; only frame beams are free of secondary beams (except for the positions with building function requirements), the structure force transmission path is direct and clear, construction is convenient and fast, vertical haunching is adopted at the beam ends, the beam end bearing capacity of continuous beams is fully utilized, the rigidity of supports is improved by increasing the thickness at the positions of the floor supports, and reinforcing bars at the positions of the supports are reduced; the prestress technology solves the problems of cracks and deflection of beams and plates under the large-span and large-load effect, the crack requirement is not needed to be met by adding steel bars, the midspan beam height is small, the floor thickness is small, the clear height of a floor is guaranteed, meanwhile, the building floor height is reduced, foundation pit supporting, earth excavation, bottom plate anti-floating reinforcement and the like are reduced for a basement, and the construction cost is reduced. Investment is saved, and comprehensive economic benefits are remarkable.
本发明公开了一种预应力混凝土加腋梁板楼盖结构，包括若干呈矩形柱网分布的框架柱、沿矩形柱网纵横向布置的连续框架梁和布置于框架梁之间的楼板，所述框架梁梁端有竖向加腋，楼板支座处有竖向加腋。本发明所述的一种楼盖结构，采用梁板结构体系，结构延性好、可靠性高；只有框架梁无次梁(有建筑功能要求处除外)，结构传力路径直接、明确，施工便捷，梁端采用竖向加腋，充分利用了连续梁的梁端承载力，楼板支座处通过增加厚度来提高支座的刚度，减少支座处配筋；预应力技术解决了大跨度大荷载作用下梁和板的裂缝、挠度，也不用通过增加钢筋来满足裂缝要求，使得跨中梁高比较小、楼板板厚比较薄，保证楼层净高的同时降低了建筑层高，对于地下室还减少了基坑支护、土方开挖、底板抗浮配筋等，节约投资，综合经济效益显著。
