The invention belongs to the technical field of connecting pieces, and particularly relates to a connecting piece for a building steel frame. The connecting piece comprises a connecting piece unit, a first rotary connecting structure, a second rotary connecting structure and a thread bushing. According to the connecting piece designed by the invention, after the connecting piece is damaged by a large tensile force, a fragile connecting sleeve is firstly and most easily damaged, after the fragile connecting sleeve is extruded and broken, a tightening pull rod loses the tightening effect on a first buckle and a second buckle, however, due to the existence of a limiting disc, a clamping block limits the first buckle and the second buckle in the axis direction of a hinged shaft, it is guaranteed that the tightening pull rod is still kept to be matched with a tensioning hole under the condition, the first buckle and the second buckle are ensured not to be separated under the condition through the tensioning hole and the limiting disc, and that is, the connecting piece designed by the invention also has a certain connecting effect after being damaged.
本发明属于连接件技术领域，尤其涉及一种建筑钢架使用的连接件，它包括连接件单元、第一旋转连接结构、第二旋转连接结构、螺纹套，本发明设计的连接件，在受到较大拉力受损后，最先和最容易破坏的是易碎连接套，在易碎连接套受到挤压破碎后，上紧拉杆就失去了对第一卡扣和第二卡扣的上紧作用，但是因限位盘的存在、卡块对第一卡扣和第二卡扣沿着铰接轴轴线方向的限位保证上紧拉杆在这种情况下还保持与拉紧孔配合，通过拉紧孔与限位盘保证这种情况下第一卡扣和第二卡扣不会脱开，即本发明设计的连接件在受损后，还具有一定的连接作用。
