Anti-sliding mixed type high-strength bolt connection joint and construction method thereof
The invention provides an anti-sliding mixed type high-strength bolt connection node and a construction method thereof.The node comprises a steel node plate provided with a plurality of bolt holes, high-strength bolts are inserted into the bolt holes, the anti-sliding mixed type high-strength bolt connection node is characterized in that the high-strength bolts comprise pressure-bearing type bolts and friction type bolts, the pressure-bearing type bolts are arranged on the outer side of a bolt group, and the friction type bolts are arranged on the outer side of the bolt group; the diameter of the pressure-bearing type bolt is close to the aperture of the bolt hole, so that pressure-bearing type stress is realized; the diameter of the friction type bolt is smaller than that of the bolt hole, and friction type stress is achieved. After the distribution mode of the high-strength bolts is selected according to use requirements, certain pre-tightening force is applied to the pressure-bearing bolts firstly, and then higher pre-tightening force is applied to the friction type bolts. Partial pressure-bearing type bolts are arranged in a traditional friction type bolt connection joint, construction feasibility and convenience are considered at the same time, and therefore ideal anti-sliding performance, fatigue performance and comprehensive economic indexes are obtained, and the friction type bolt connection joint has the advantages of being good in anti-sliding performance, reasonable in stress, convenient to construct and high in economic benefit.
本发明提供了一种抗滑移的混合型高强螺栓连接节点及其施工方法，该节点包括开有若干螺栓孔的钢节点板，螺栓孔中插入有高强螺栓，其特征在于：所述高强螺栓包括承压型螺栓和摩擦型螺栓，在螺栓群外侧布置承压型螺栓，内部布置摩擦型螺栓，其中，承压型螺栓直径与螺栓孔孔径接近，实现承压型受力；摩擦型螺栓直径小于螺栓孔孔径，实现摩擦型受力。根据使用需求选择高强螺栓的分布方式后，先对承压型螺栓施加一定预紧力，再对摩擦型螺栓施加更高的预紧力。本发明通过在传统摩擦型螺栓连接节点中设置部分承压型螺栓，同时兼顾施工可行性和便捷性，从而获得理想的抗滑移性能、疲劳性能和综合经济指标，具有抗滑移性能好、受力合理、施工方便、经济效益高的优点。
