Abstract

The invention relates to a self-limiting multidirectional tensile friction damper which comprises pre-pressed bolts, an upper connection plate, an upper friction plate, rigid connection rods, a middle friction plate and a lower friction plate. The middle friction plate is arranged above the lower friction plate, the upper friction plate is arranged above the middle friction plate, and the upper connection plate is arranged above the upper friction plate. Upper limit through holes are formed on the upper friction plate, the upper connection plate is integrally and fixedly connected with the middle friction plate through the plurality of rigid connection rods, the number of the rigid connection rods is matched with that of the upper limit through holes, and each rigid connection rod penetrates through one upper limit through hole. The upper friction plate is fixedly connected with the lower friction plate through the pre-pressed bolts, and the pre-pressed bolts exert pre-tightening force on the upper friction plate, the middle friction plate and the lower friction plate. The self-limiting multidirectional tensile friction damper can provide large friction damping force in all directions of a plane, has a limiting function and a certain vertical tensile capability, and has the advantages of being simple and compact in structure, convenient to use, etc.

Description

technical field [0001] The invention relates to a shock-isolation building damper, in particular to a self-limiting multi-directional tensile friction damper. Background technique [0002] At present, the dampers widely used in earthquake-isolated buildings include: U-shaped dampers, annular steel rod dampers, oil dampers, and friction dampers. However, most of the existing friction dampers have the disadvantages of easy loss of friction force, weak tensile capacity, and only one-way deformation. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, to provide a self-limiting multi-direction that can provide a large frictional damping force in all directions in the plane and also has a position-limiting function and a certain vertical tensile capacity. Anti-pull friction damper. [0004] According to the technical solution provided by the present invention, the self-limiting multidirectional tensile fric...
