Joint of concrete pile and steel beam of inner pipe reinforced type square sleeve square hollow interlayer steel pipe
The invention relates to a joint of a concrete pile and a steel beam of an inner pipe reinforced type square sleeve square hollow interlayer steel pipe. The joint comprises an outer square steel pipe1, an inner square steel pipe 2, a reinforcement ring 3, stiffening ribs 4, concrete 5, a steel beam 6 and a welding seam 7. The square inner pipe stiffening ribs of the square inner pipe are symmetrically welded to the outer surface, in the length direction, of square inner pipe in the joint region, the reinforcement ring is welded to the outer square steel pipe, and the steel beam and the reinforcement ring are connected in a welded manner. The joint has the advantages of being convenient to assemble on site, reliable in performance, good in anti-seismic and fireproof performance and the like, the damage that the four sides of the square steel pipe of the joint core area are bent inwards can be effectively reduced through the inner square steel pipe with the reinforcement ribs arranged in the joint core area, the contact area of the inner square steel pipe and the concrete is increased, the rigidity and anti-deformation capacity of the joint core area are increased, the force transmission path is clear, and bearing force is high.
本发明涉及一种内管加强型方套方中空夹层钢管混凝土柱与钢梁的节点，包括方钢管1、内方钢管2、加强环3、加劲肋4、混凝土5、钢梁6、焊缝7；所述方内管加劲肋在节点域处对称焊接在方内管长度方向的外表面上，加强环焊接在外方钢管上，钢梁与加强环采用焊接的方式连接。本发明具有现场装配方便、性能可靠、抗震及抗火性能好等优点，节点核心区内设加劲肋的内方钢管可以有效减少节点核心区方钢管四条边向内屈曲破坏，增加内方钢管与混凝土的接触面积，增加了节点核心区的刚度和抗变形能力，传力路径明确，承载力高。
