Node connecting structure of rectangular concrete filled steel tubular column and I-shaped steel concrete composite beam
The invention discloses a node connecting structure of a rectangular concrete filled steel tubular column and an I-shaped steel concrete composite beam, which comprises an I-shaped steel connecting block, two vertical flange plates and a transverse web plate of the I-shaped steel connecting block are welded and fixed on a vertical steel plate of a prefabricated rectangular reinforced concrete column, and an end plate is welded and fixed at one end of the I-shaped steel connecting block; prefabricated ECC reinforced concrete is arranged in the upper groove and the lower groove of the I-shaped steel connecting block; one ends of a plurality of longitudinal steel bars of a reinforcing mesh of the ECC reinforced concrete are accommodated in a plurality of steel bar through holes of the vertical steel plate in a one-to-one correspondence manner and are fixed in the reinforced concrete of the rectangular reinforced concrete column; and respective connecting ends of the I-shaped steel connecting block and the I-shaped steel concrete composite beam are screwed and fixed through a plurality of sets of high-strength threaded fasteners and four steel connecting plates. If an earthquake occurs, the beam can rotate up and down around the node connecting structure, the node connecting structure is good in ductility, high in plastic deformation capacity and excellent in anti-seismic and cushioning performance.
本发明公开了一种矩形钢管混凝土柱与工字钢混凝土组合梁的节点连接结构，包括工字钢连接块，工字钢连接块的两竖向翼缘板和横向腹板焊接固定在预制的矩形钢筋混凝土柱的一竖向钢板上，工字钢连接块的一端焊接固定有一端板，工字钢连接块的上凹槽和下凹槽内均有预制的ECC钢筋混凝土，ECC钢筋混凝土的钢筋网的多根纵向钢筋的一端一一对应容置在所述竖向钢板的多个钢筋过孔内并固定在矩形钢筋混凝土柱的钢筋混凝土内；工字钢连接块与工字钢混凝土组合梁的各自连接端经多套高强螺纹紧固件和四块钢连接板螺接固定。若遇到地震梁能绕节点连接结构上下转动、节点连接结构延展性能好、节点连接结构的塑性变形能力强和抗震缓震性能优越。
