A Bridge Reinforcement Device with Both Seismic Isolation Function

Abstract

The invention provides a bridge reinforcement device with a shock isolation function, which relates to the technical field of bridges, and solves the problem that when the internal parts of a hydraulic telescopic rod are damaged, the support reinforcement will easily fail, which will easily lead to dangerous accidents. After the rod is damaged, the auxiliary structure realizes auxiliary locking at the same time; it cannot realize the synchronous fixation of multiple ground nails, and cannot realize the synchronous removal of multiple ground nails in linkage when the hydraulic telescopic rod shrinks. A bridge reinforcing device with a shock-isolation function, comprising a base; a fixed structure is plugged into the base, and a hydraulic telescopic rod is fixedly connected to the base through bolts. When the hydraulic telescopic rod shrinks, the toggle rod B moves down with the main body seat, and at this time the toggle rod B is in contact with the heads of the two toggle rods A at the same time, and the head end of the toggle rod A is in contact with the main body seat, so that the When the hydraulic telescopic rod is retracted, the removal of the fixed structure can be realized.

Description

technical field [0001] The invention belongs to the technical field of bridges, and more specifically relates to a bridge reinforcing device with a shock-isolation function. Background technique [0002] Bridge reinforcement is to improve the bearing capacity and service performance of components and even the entire structure through certain measures to meet new requirements. That is to say, it is necessary to deal with the situation that the bridge cannot meet the continuous use. [0003] For example, the application number: CN201810430126.0, the invention discloses a highway bridge reinforcement device, including a bridge base, the top of the bridge base is provided with a bridge support column, the top of the bridge support column is provided with a bridge plate, and the bridge support column Both sides of the bridge base are provided with a first support seat on the top of the bridge base, a first groove is opened on the top of the first support seat, and a first suppor...

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a bridge reinforcement device with the function of shock isolation to solve the existing problem that the existing reinforcement devices are often realized by hydraulic expansion, when the internal parts of the hydraulic expansion rod are damaged It is easy to cause the failure of support reinforcement, and then it is easy to lead to dangerous accidents, and the auxiliary structure cannot realize auxiliary locking at the same time after the hydraulic telescopic rod is damaged; moreover, the fixing structure of the existing device is inefficient and cannot realize multiple ground nails. The synchronous fixation of the hydraulic telescopic rod cannot be synchronized to realize the synchronous removal of multiple ground nails when the hydraulic telescopic rod is contracted
