Abstract

The joint end of the bridge end plate and the bridge is made into an arc-shaped head, and shaft holes are set on both sides of the joint end, and the channel steel is fixed at the contact between the bridge end plate and the cover beam, and the two ends of the channel steel Set the sealing plate, when installing, the arc-shaped head of the bridgehead strapping plate extends into the groove of the channel steel, the sealing plate is put into the shaft hole of the bridgehead strapping plate through the short axis, and fixed on the two ends of the channel steel with bolts. In the process of subgrade settlement, the arc-shaped head of the bridge head slab will turn out from the groove of the channel steel to prevent the appearance of gaps, and the subgrade that has settled under the slab can be filled through the grouting holes on the slab .

Description

technical field [0001] The invention relates to a bridge head strapping plate, in particular to a connecting device at a bridge head strapping plate and a bridge joint. Background technique [0002] Due to the influence of the genetic force of the road surface and the bridge, as well as the difference in the stiffness of the road and bridge, it is inevitable that the uneven settlement of the bridge head will cause the settlement difference phenomenon. Especially at the connection between the newly built road and the bridge, due to the large height difference, there will be a large gap between the board and the bridge, which will cause the phenomenon of vehicle jumping, which is a hidden danger of traffic accidents for driving , is not conducive to driving safety. Contents of the invention [0003] In order to solve the problem of vehicle jumping at the bridge head, the present invention provides a connecting device for the bridge head. The device is provided with movable ...
