Length-adjustable suspender connecting piece
The invention relates to a length-adjustable suspender connecting piece, and belongs to the technical field of vibration control of a structural vibration resistance technology. Peripheral distributed pull rod structures are uniformly arranged at the tops of adjacent gaps of a fence-shaped barrel structure in the suspender connecting piece through tooth-shaped links on pull rods; the periphery distributed pull rod structure is fixed in the fence-shaped barrel structure through a plurality of groups of displacement constraints formed by displaceable constraint steel hoops, arc-shaped short steel columns and the displaceable constraint steel hoops outside the fence-shaped barrel structure, and each displaceable constraint steel hoop is sealed and constrained by the side edge of a vertical regulator; and an internal mass block capable of moving up and down along the inner wall surface of the regulator is arranged in the vertical regulator, and when vertical vibration is generated, the internal mass block drives the vertical regulator to move up or down, part or all of the displaceable constraint steel hoops are automatically separated, and the peripheral distributed pull rod structures are driven to move down to adjust the length of the suspender. The invention provides a connecting piece for changing the overall length of a connected suspender by adjusting the number of peripheral constraint steel hoops during vertical vibration, and the connecting piece is suitable for composite structure systems such as a suspension bridge, a cable-stayed bridge and a tied-arch bridge.
本发明涉及一种可调长度的吊杆连接件，属于结构抗振技术的振动控制技术领域。该吊杆连接件中栅栏状筒体结构相邻缝隙处顶部均匀通过每个拉杆上的齿状链接设有周边分布式拉杆结构，栅栏状筒体结构外部通过可位移约束钢箍、弧形短钢柱、可位移约束钢箍形成的若干组位移约束将周边分布式拉杆结构固定在栅栏状筒体结构内部，每个可位移约束钢箍通过竖向调节器侧边封固约束，竖向调节器内部设有能延调节器内壁面上下移动的内部质量块，当产生竖向振动时，内部质量块带动竖向调节器向上或向下移动，部分或全部可位移约束钢箍将自动脱离，带动周边分布式拉杆结构向下移动调节吊杆长度。本发明提供在竖向振动时，通过调整周边约束钢箍数量来改变所链接吊杆整体长度的连接件，适用于悬索桥、斜拉桥、系杆拱桥等组合结构体系。
