High-energy-consumption concrete-filled steel tube beam-column joint structure and construction method
The invention relates to a high-energy-consumption concrete-filled steel tube beam-column joint structure and a construction method. The section area of a concrete-filled steel tube structure is small, and if concrete-filled steel tube beams and columns are adopted at the same time, the connecting joint area is small, stress concentration is prone to occurring, and reliability is poor. The structure comprises a concrete-filled steel tubular column and a hollow concrete-filled steel tubular beam, wherein one end of the hollow concrete-filled steel tubular beam is connected to the side wall of the concrete-filled steel tubular column; the concrete filled steel tubular column comprises a vertical square tube, and concrete is poured in the vertical square tube; the hollow steel pipe concrete beam comprises an inner square pipe and an outer square pipe, and concrete is poured between the inner square pipe and the outer square pipe; shear nails are arranged on the side walls of the vertical square tubes, one ends of the shear nails are fixed to the near beam walls of the vertical square tubes, and the other ends of the shear nails are inserted between the inner square tubes and the outer square tubes and embedded in concrete between the inner square tubes and the outer square tubes. The structure can effectively enhance the stress strength of the concrete-filled steel tube column beam joint, is provided with the replaceable low-yield-point steel plate, enhances the self energy consumption performance, and is convenient to install and maintain.
本发明涉及一种高耗能钢管混凝土梁柱节点结构及施工方法。钢管混凝土结构截面面积小，若同时采用钢管混凝土梁和柱，连接节点面积较小，易应力集中，可靠性差。本结构包括钢管混凝土柱和空心钢管混凝土梁，空心钢管混凝土梁的一端连接到钢管混凝土柱的侧壁；钢管混凝土柱包括竖向方管，竖向方管内浇筑有混凝土；空心钢管混凝土梁包括内方管和外方管，内方管和外方管之间浇筑有混凝土；竖向方管的侧壁设置有剪力钉，一端固定到竖向方管的近梁壁，另一端插入内方管和外方管之间并埋入内方管和外方管之间的混凝土内。本结构能够有效增强钢管混凝土柱梁节点的受力强度，并配有可更换的低屈服点钢板，加强自身的耗能性，并且便于安装维护。
