Core tube flange closed section column joint with self-tapping bolts and construction method of core tube flange closed section column joint
The invention relates to the technical field of civil engineering, and particularly discloses a core tube flange closed section column joint with self-tapping bolts and a construction method of the core tube flange closed section column joint. The core tube flange closed section column joint comprises a lower-layer steel column and an upper-layer steel column, a flange plate is arranged between the upper-layer steel column and the lower-layer steel column, and the upper-layer steel column is detachably connected with the lower-layer steel column through the flange plate; a core tube is arranged in the lower-layer steel column and connected with the lower-layer steel column through welding, and the upper part of the core tube is embedded in the upper-layer steel column; self-tapping bolt holes are formed in the four side column walls of the bottom end of the upper-layer steel column at intervals, self-tapping bolt holes are further formed in the upper part of the core tube, and the coretube is connected with the upper-layer steel column through the self-tapping bolts; and partition plates are arranged inside the lower-layer steel column and at the bottom end of the core tube, and the partition plates make close contact with the inner wall of the lower-layer steel column and are fixedly connected with the inner wall of the lower-layer steel column. The joint domain rigidity canbe effectively enhanced, and safety and reliability are achieved; the structure is simple and assembling is rapid; and the problems that a traditional full-penetration welding joint is low in field welding construction efficiency, poor in welding quality and the like are solved, and the construction efficiency is greatly improved.
本发明涉及土木工程技术领域，具体公开了一种带自攻螺栓的芯筒法兰闭口截面柱节点及其施工方法。其中，该节点包括下层钢柱和上层钢柱，上层钢柱及下层钢柱之间设置有法兰板，上层钢柱与下层钢柱通过法兰板可拆卸连接；下层钢柱内部设置有芯筒，芯筒通过焊接与下层钢柱连接，芯筒上部嵌套于上层钢柱中；上层钢柱底端四侧柱壁间隔设置自攻螺栓孔，芯筒上部也设置自攻螺栓孔，芯筒与上层钢柱通过自攻螺栓连接；下层钢柱内部，芯筒底端设置有隔板，隔板与下层钢柱内壁紧密接触并固定连接。本发明能够有效加强节点域刚度，安全可靠；结构简单，装配迅速；解决了传统全熔透焊接节点现场焊接施工效率低、焊接质量差等问题，极大提高施工效率。
