The invention discloses a friction pendulum support for anti-fall beam damping cables, which comprises a main body of the friction pendulum support. The top of the main body of the friction pendulum support is provided with a plurality of upper anchoring structures. The upper anchor structures include: pre-tightening force bolts, On the main body of the friction pendulum support, the screw rod of the pre-tightening force bolt protrudes above the main body of the friction pendulum support, and a pre-tightening force pin hole is opened on the screw rod of the pre-tightening force bolt; the pre-tightening force nut is sleeved on the pre-tightening force The force bolt extends to the screw rod at one end above the main body of the friction pendulum support; the pre-tightening force spring is sleeved on the pre-tightening force bolt, and the pre-tightening force spring is arranged between the main body of the friction pendulum support and the pre-tightening force nut; The pre-tightening force locking pin is detachably passed through the pre-tightening force pin hole. The anti-drop beam damping cable friction pendulum support can avoid safety accidents caused by insufficient pre-tightening force, excessive pre-tightening force or uneven force on each pre-tightening force bolt during installation and use of the support, and avoid damage to the construction. Cause harm and avoid damage to the safety of users' lives and property.
Description
technical field [0001] The invention relates to the technical field of anti-seismic bearings for bridges and buildings, in particular to an anti-fall beam damping cable friction pendulum bearing. Background technique [0002] In recent years, there have been vicious accidents of bridge collapse or partial damage at home and abroad, which have caused huge losses to the lives and property of people in various countries. caused by exceeding the bearing capacity of the structure. Therefore, in order to ensure the stress and operation safety of the bridge, it is of great significance and urgency to monitor the stress state and service state of the bridge in real time. [0003] The bridge support is the key component connecting the upper structure and the lower structure of the bridge. Various loads of the upper structure, including beam self-weight, vehicle live load, additional force and other main loads, are transmitted to the bridge pier and foundation through the support, an...
