Energy-absorbing and vibration-reducing suspender and bridge floor connecting device

Abstract

The invention discloses an energy-absorbing and vibration-reducing suspender and bridge floor connecting device. The suspender and bridge floor connecting device comprises a suspender, an anchoring flange is arranged at the end of the suspender after the lower end of the suspender penetrates through a bridge floor, and an elastic curved-surface cushion block and a curved-surface suspender connecting piece are sequentially arranged on the suspender between the anchoring flange and the lower side of the bridge floor from top to bottom; and the upper side of the elastic curved-surface cushion block makes contact with the lower side of the bridge floor, the lower side of the curved-surface suspender connecting piece makes contact with the upper side plane of the anchoring flange, and the lowerside of the elastic curved-surface cushion block makes contact with the upper side curved surface of the curved-surface suspender connecting piece. The device has the characteristics of energy absorption, vibration reduction, no limitation of factors such as designed elevation and attractive appearance, simple construction and easy later maintenance.

Description

technical field [0001] The invention relates to a connecting device between a suspension rod and a bridge deck, in particular to an energy absorbing and vibration-reducing connecting rod and a bridge deck connecting device. Background technique [0002] As an important tension member in the bridge structure, the suspender system is widely used in various bridge types, and it mainly bears the dead load of the bridge deck and the live load of the vehicle. During the operation of the bridge, the boom system not only needs to bear the static force brought by the dead load, but also needs to bear the long-term alternating load caused by the vehicle load. Under the vehicle-bridge coupling, the boom system not only bears the vertical tension and impact, but also receives the bending moment and shear force generated by the lateral vibration and longitudinal vibration, so that the boom system, especially the connection between the boom and the bridge deck , prone to stress corrosion...

Problems solved by technology

However, limited by factors such as design elevation and aesthetics, the operating range is limited

2) The connection method between the suspender and the bridge deck is changed from fixed connection to hinged or semi-hinged, which greatly reduces the influence of bending moment and shear force on the suspender, but increases the difficulty of construction, and will also be affected by corrosion and dust in the later operation process. Factors such as blockage
