X-shaped oblique crossing energy consumption connecting joint free of axial force influence
The invention discloses an X-shaped oblique crossing energy consumption connecting joint free of the influence of axial force. The X-shaped oblique crossing energy consumption connecting joint comprises a friction force transmission piece, a connecting plate and a friction structure. The friction force transmission piece and the connecting plate are connected with the X-shaped node, the connecting plate is vertically connected with the friction force transmission piece in a sliding mode, the friction structure is installed on the side wall of the friction force transmission piece in a pressed mode through the cover plate, the connecting plate is connected with the friction structure through the limiting structure, and when the connecting plate and the friction force transmission piece generate vertical relative displacement, the connecting plate is connected with the friction structure through the limiting structure. The limiting structure drives the friction structure to vertically move along the friction force transmission piece; when the energy dissipation node is subjected to tension reduction or compression reduction composite stress, the energy dissipation node can decouple axial force and shearing force of the node through different force transmission paths, when the shearing force borne by the node is larger than static friction force of a friction structure, the friction force transmission piece and the connecting plate generate dislocation displacement, and the outer cover plate is driven by the baffle fixedly connected with the connecting plate to generate vertical displacement; and meanwhile, a dovetail block of the friction force transmission piece is in close contact with a dovetail groove of the connecting plate, so that additional axial force is transmitted.
本发明公开了一种免除轴力影响的X形斜交耗能连接节点，包括摩擦传力件、连接板和摩擦结构；摩擦传力件和连接板分别于X形节点连接，所述连接板与摩擦传力件竖向滑动连接，所述摩擦结构通过盖板压装在摩擦传力件的侧壁上，连接板通过限位结构与摩擦结构连接，当连接板和摩擦传力件发生竖向相对位移时，限位结构驱使摩擦结构沿摩擦传力件竖向移动；当耗能节点受到拉减或压减复合受力时，该耗能节点可将节点的轴力与剪力通过传力路径不同解耦，当节点受剪力大于摩擦结构的静摩擦力，摩擦传力件与连接板发生错位位移，通过与连接板固接的挡板带动外盖板发生竖向位移，从而带动预紧力螺栓驱动内盖板发生竖向位移实现剪切耗能，同时摩擦传力件的燕尾块与连接板的燕尾槽紧密接触实现传递附加轴力。
