Abstract
一种高强钢筋超高强混凝土框支柱,涉及钢筋砼框支柱。克服了普通钢筋砼框支柱、型钢砼框支柱轴压比限值低,地震力下保护层易脱落、纵筋和型钢翼缘易屈曲、震后难修复、无法应用高强钢筋和超高强砼的缺陷;克服了型钢砼框支柱和钢管砼框支柱节点构造复杂、钢管砼框支柱对砼约束不充分、钢管易屈曲的缺陷。本发明由纵向高强钢筋、高强封闭箍筋、自密实超高强砼组成;约束包括砼保护层在内整个砼的箍筋间距30-35mm,其外表面与混凝土框支柱外表面平齐,约束纵向钢筋的箍筋间距60-120mm。通过密配高强焊接封闭箍筋对整个混凝土的约束,改善超高强混凝土的力学性能,提高柱子抗震性能,本发明在高层及超高层结构中具有广阔应用前景。
The utility model relates to a high-strength reinforced concrete frame pillar and relates to a reinforced concrete frame pillar. It overcomes the problems of low axial pressure ratio limit of ordinary reinforced concrete frame pillars and shaped steel concrete frame pillars, easy falling off of the protective layer under earthquake force, easy buckling of longitudinal bars and shaped steel flanges, difficult repairs after earthquakes, and inability to apply high-strength steel bars and ultra-high-strength concrete Defects: Overcome the defects of complex joint structure of steel-concrete frame pillars and steel pipe concrete frame pillars, insufficient restraint of concrete by steel pipe concrete frame pillars, and easy buckling of steel pipes. The invention is composed of longitudinal high-strength steel bars, high-strength closed stirrups, and self-compacting ultra-high-strength concrete; the stirrup spacing of the entire concrete including the concrete protective layer is constrained to 30-35mm, and its outer surface is flush with the outer surface of the concrete frame pillar, constraining the longitudinal The stirrup spacing of steel bars is 60-120mm. The close-fitting high-strength welding seals the stirrup to restrain the entire concrete, improves the mechanical properties of the ultra-high-strength concrete, and improves the seismic performance of columns. The invention has broad application prospects in high-rise and super high-rise structures.
