Prefabricated steel tube bundle partially-prestressed concrete beam and construction method thereof
The invention discloses a prefabricated steel tube bundle partially-prestressed concrete beam and a construction method thereof. The beam comprises a hollow lattice type steel tube bundle, concrete, prestressed steel bars, baffles and anchoring steel bars, wherein the baffles are fixed to the two ends of the interior of the hollow lattice type steel tube bundle; a plurality of prestressed bar holes are formed in the lowermost layer of the baffle of a lowermost steel member, and a plurality of preformed holes are formed in other layers; the other baffles are provided with a plurality of layers,wherein a plurality of preformed holes are formed in each layer; the prestressed steel bars are arranged in the prestressed bar holes in a sliding manner and penetrate through the whole beam; the prestressed steel bars are loaded with control stress and anchored; the anchoring steel bars are inserted into the preformed holes and fixed; and concrete is poured between the baffles, and after strength requirements are met, prestress is released, and therefore the steel tube bundle partially-prestressed concrete beam is formed. The beam combines advantages of a steel reinforced concrete structureand a prestressed concrete structure, so that the anti-vibration property and the anti-deformation capacity of the beam are improved, the bearing capacity is high, the later-period bearing capacity isstable, and the structural rigidity is greatly improved.
本发明公开了一种预制钢管束部分预应力混凝土梁及其施工方法。该梁包括空心格构式钢管束、混凝土、预应力钢筋、挡板和锚固钢筋；挡板固定于空心格构式钢管束内部的两端；最下层一榀钢构件的挡板的最下一层设置有若干个预应力筋孔，其他层设置有若干个预留孔；其他挡板设置有若干层、每层若干个预留孔；预应力钢筋滑动设置于预应力筋孔中并贯穿整个梁；预应力钢筋加载控制应力并锚固；锚固钢筋插入预留孔中并固定；在挡板之间浇筑混凝土，达到强度要求后，释放预应力，形成钢管束部分预应力混凝土梁。该梁兼具型钢混凝土结构和预应力混凝土结构的优点，提高了梁的抗震性能和抗变形能力，承载能力高且后期承载力稳定，结构刚度大幅度提升。
