Description

A connection structure of bridge expansion joints

technical field

The utility model relates to the technical field of bridge expansion joints, in particular to a connection structure of bridge expansion joints.

Background technique

Bridge expansion joints refer to expansion joints usually set between two girder ends, between the girder end and abutment or at the hinged position of the bridge in order to meet the deformation requirements of the bridge deck. The expansion joints are required to be free to expand and contract in two directions parallel and perpendicular to the bridge axis, firm and reliable, and the vehicles should run smoothly, without sudden jumps and noises; the bridge expansion joints are used to adjust the load caused by the vehicle load and bridge construction materials. The displacement and connection between the superstructure. There are following problems at prior art:

1. After the bridge expansion joint structure is installed and connected, the bridge expansion joint will have a gap required for the movement space when the bridge expands with heat and contracts with cold, and deforms. This gap will cause bumps when facing the vehicle and affect the comfort of the vehicle when passing. When faced with bicycles with wide tires and thinner wheel diameters, the tires are easy to get stuck in the gaps, and it is more dangerous for bicycles to pass through;

2. At present, during the construction of bridge expansion joints, the bridge expansion joints are fixed by cement. It takes a certain time for the cement to solidify. After the installation is completed, the bridge expansion joints will not be open to traffic in a short time, which will affect the normal traffic.
