Beam-column joint adopting self-locking anchoring part and multi-cavity steel pipe column to realize unilateral connection
The invention relates to the technical field of building steel structures in civil engineering, in particular to a beam-column joint achieving unilateral connection through self-locking anchoring parts and multi-cavity steel pipe columns. The multi-cavity steel pipe column comprises a cross-shaped steel framework, a full-thread lead screw, self-locking type anchoring parts, high-strength bolts, thin-wall angle steel and a steel beam, the full-thread lead screw penetrates through the steel framework, the two ends of the full-thread lead screw are connected with the self-locking type anchoring parts through threads, the thin-wall angle steel and the cross-shaped steel framework are welded to form the multi-cavity steel pipe column, and the high-strength bolts are screwed outside the steel pipe column. The high-strength bolt can drive the self-locking type anchoring part to rotate clockwise while rotating clockwise, and the self-locking type anchoring part can move towards the inner wall of the column along the full-thread lead screw and abut against the inner side of the wall of the column. And the high-strength bolt is continuously screwed, the self-locking anchoring part does not rotate any more, and screwing can be continuously carried out until the designed pre-tightening force of the bolt is achieved. The scheme for realizing single-side connection does not depend on a bolt form, but depends on a cylinder structure design and an anchoring part self-locking design, so that the node connection stress is more reasonable.
本发明涉及土木工程中建筑钢结构技术领域，涉及一种采用自锁式锚固件和多腔钢管柱实现单边连接的梁柱节点。它包括十字型钢骨架、全螺纹丝杆、自锁式锚固件、高强度螺栓、薄壁角钢和钢梁，全螺纹丝杆穿过钢骨架，两端通过螺纹连接自锁式锚固件，将薄壁角钢与十字型钢骨架焊接形成多腔钢管柱，在钢管柱外对高强度螺栓施拧，高强度螺栓在顺时针转动的同时会带动自锁式锚固件顺时针旋转，自锁式锚固件会沿着全螺纹丝杆向柱内壁方向移动并顶紧柱壁内侧。继续旋拧高强度螺栓，自锁式锚固件不再转动，可继续施拧至达到螺栓设计预紧力。本发明实现单边连接的方案不依赖螺栓形式，而是依赖于柱体结构设计和锚固件自锁式设计，使得节点连接受力更加合理。
