Damping oil pressure damper for steel structure connection nodes
The invention discloses a damping oil pressure damper for connection nodes in a steel structure, which comprises a front pull rod, a rear pull rod and a tubular node box, wherein the node box is of aclosed structure, the inner cavity of the node box is filled with damping oil to form an oil cavity, the middle of the oil cavity in the node box is sleeved with a piston body in a matched manner, andthrust springs are respectively connected between a movable spring seat and a fixed spring seat on two sides of the piston body; a sliding pipe is axially fixed at the axial center position of the piston body, two ends of the sliding pipe are respectively matched and sleeved in sliding sleeves at the two ends and are capable of sliding, and strip-shaped oil-saving holes are formed in the side surfaces of the sliding sleeves at the two ends. According to the invention, when the front pull rod and the rear pull rod of the node box are pulled or compressed, the piston body inside the node box can be driven to move in the axial direction, and then the sliding pipe is driven to slide in the sliding sleeve, so that oil resistance change adjustment can be automatically carried out, vibration frequency and vibration amplitude of the nodes are changed, and energy can be effectively dissipated and vibration can be reduced.
本发明公开了一种钢结构连接节点的减震油压阻尼器，包括前拉杆、后拉杆和管状的节点盒，节点盒为密闭结构，其内腔充满阻尼油形成油腔，在节点盒内的油腔中部匹配套装有活塞体，在活塞体两侧的动弹簧座与定弹簧座之间分别连接有推力弹簧；在所述活塞体的轴心位置沿轴向固定有滑管，滑管的两端分别匹配套装于两端滑套内且能够滑动，在两端滑套的侧面开有条形节油孔。本发明中位于节点盒前后端的拉杆被拉动或压缩时，能够带动节点盒内部的活塞体沿轴向移动，进而带动滑管在滑套内滑动，能够自动进行油阻变化调节，从而改变节点的震动频率和震动幅度，能够有效消能和减少震动。
