The invention discloses a collapse-proof girder damping inhaul cable friction swing support which comprises a friction swing support body. A plurality of upper anchoring structures are arranged at thetop of the friction swing support body. Each upper anchoring structure comprises a pre-tightening force bolt arranged on the friction swing support body, a pre-tightening force nut sleeving the screwat the end, stretching out to the portion above the friction swing support body, of the pre-tightening force bolt, a pre-tightening force spring sleeving the pre-tightening force bolt, and a pre-tightening force locking pin detachably penetrating into a pre-tightening force pin hole, wherein the screw of the pre-tightening force bolt stretches out to the portion above the friction swing support body, the pre-tightening force pin hole is formed in the screw of the pre-tightening force bolt, and the pre-tightening force spring is arranged between the friction swing support body and the retightening nut. The collapse-proof girder damping inhaul cable friction swing support can avoid safety accidents caused by not large enough pre-tightening force or excessively large pre-tightening force oruneven stress of each pre-tightening force bolt in the installing and using process of the support, the damage to construction is avoided, and the damage to life and property safety of users is avoided.
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...
