Core tube flange closed section column connecting joint with prestressed steel pull rod and connecting method
The invention relates to the technical field of fabricated steel structures, and particularly discloses a core tube flange closed section column connecting joint with a prestressed steel pull rod anda design method thereof. The connecting joint comprises a first tubular column, a second tubular column, a core tube and the prestressed steel pull rod, a first flange is arranged on the bottom end face of the first tubular column, and a second flange is arranged on the top end face of the second tubular column; the first flange and the second flange can be fixedly connected through flange bolts;and a plurality of one-way bolt holes are formed in the column wall, close to the first flange, of the first tubular column, the core tube can be arranged on the first tubular column and the second tubular column in a penetrating mode and can be connected with the first tubular column through one-way bolts and hole channels, and an upper tubular column and a lower tubular column are fastened together through the prestress steel pull rod. The flanges and the core tube are adopted, industrial production is facilitated, the core tube and the column wall are connected through the one-way bolts, the connecting structure performance is guaranteed, meanwhile, due to the existence of the prestress steel pull rod, the bolt tension can be effectively reduced, and efficient fabricating is achieved.
本发明涉及装配式钢结构技术领域，具体公开了一种带预应力钢拉杆的芯筒法兰闭口截面柱连接节点及其设计方法。该连接节点包括：1号管柱、2号管柱、芯筒以及预应力钢拉杆，其中，1号管柱底部端面设有1号法兰，2号管柱顶部端面具有2号法兰；1号法兰与2号法兰能够通过法兰螺栓固定连接；1号管柱上靠近1号法兰的柱壁上设置有多个单向螺栓孔，芯筒能够穿设在1号管柱和2号管柱，并能够通过单向螺栓经孔道与1号管柱连接，通过预应力钢拉杆将上下管柱紧固在一起。本申请采用法兰和芯筒便于产业化生产，通过单向螺栓将芯筒、柱壁以连接，保证了连接结构性能，同时预应力钢拉杆的存在，能够有效减小螺栓拉力，实现了高效装配。
