Bridge reinforcing device

Abstract

The invention discloses a bridge reinforcing device and belongs to the technical field of bridges, the bridge comprises a top plate, a bottom plate and a plurality of box girders supported between the top plate and the bottom plate, and the box girders are arranged in the transverse direction of the bridge. The reinforcing device comprises a box girder flange plate supporting plate, a supporting clamping plate, a plurality of first box girder web tightening rods and a plurality of second box girder web tightening rods, reinforcing layers are arranged on the inner sides of the box girders in a cast-in-place mode, and the two ends of the first box girder web tightening rods and the two ends of the second box girder web tightening rods are fixedly connected with the reinforcing layers of the two adjacent box girders. The first box girder web tightening rod and the second box girder web tightening rod are located in two planes with different heights respectively, and the first box girder web tightening rod and the second box girder web tightening rod are staggered in the vertical direction. The device can be used for repairing and reinforcing the bridge, larger potential safety hazards are avoided, traffic pressure is relieved, and the service life of the bridge is prolonged.

Description

technical field [0001] The invention belongs to the technical field of bridges, and in particular relates to a bridge reinforcing device. Background technique [0002] With the rapid development of my country's economy, the development of my country's heavy-duty transport vehicles has gradually matured, and the load-carrying capacity of vehicles has continued to increase. At the same time, vehicle overload is also inevitable. During the long-term use of bridges, some cracks in the middle will occur. Therefore, Therefore, there is an urgent need to provide a bridge reinforcement device, which can be used to repair and reinforce bridges, avoid greater potential safety hazards, relieve traffic pressure, and increase the life span of bridges. Contents of the invention [0003] In view of this, the object of the present invention is to provide a bridge reinforcement device, which can be used to repair and reinforce bridges, avoid greater potential safety hazards, relieve traffic...
