Abstract

The invention discloses a bridge limiting device. A pressure-bearing elastic piece is installed between an upper anchoring device and an steering device of the bridge limiting device. The upper anchoring device, the steering device and a lower anchoring device are provided with tension cables for connection; the deformation range of a support is within the allowable deformation range; the deformation of the support is mainly adapted to pressed deformation of a pressure-bearing elastic piece; when an allowable deformation range is exceeded, that is, the upper anchoring device is in contact withthe steering device, the upper anchoring device adapts to the steering device through deformation of the tension cable, double guarantees are provided for restraining horizontal and vertical relativedisplacement between a beam body and a pier stud, overlarge horizontal sliding of the beam body is limited, and vertical disengaging of the beam body is also prevented; a pre-warning device is connected with the upper anchoring device and the steering device through wires, when the upper anchoring device makes contact with the steering device, a loop is formed, the pre-warning device generates warning information in real time, a bridge structure is effectively prevented from being further damaged, and the pre-warning device is used in the field of bridge engineering.

Description

technical field [0001] The invention relates to the field of bridge engineering, in particular to a bridge limiting device. Background technique [0002] The bridge structure is a node project in a transportation hub, and it needs to ensure its safety under normal use and extreme disasters. The bearing is an important force-transmitting component of the bridge structure. Its main function is to transfer most of the load (including dead load and live load) of the bridge superstructure to the bridge pier, and at the same time adapt to the load and temperature of the superstructure. Such as the horizontal displacement of the end, various deformations such as corners, etc. Bridge disasters in the past show that the support is the weak link in the service process of the bridge, and there may be excessive sliding of the support and the phenomenon of support void, which will lead to structural damage or even collapse. [0003] In order to prevent excessive horizontal slippage of ...
