Description

Structural Bearings

The present invention relates to a bridge device of a bridge structure, and more particularly, to a bridge device that allows thermal displacement of a bridge deck and buffers a lateral impact force suddenly acted by an earthquake so as not to overload the bridge.

In general, the bridge device is a device installed so that the top plate, which is the slab structure of the bridge, is properly placed on the bridge supporting the bridge, and has various forms and functions according to the bridge specification or the supporting load.

One of the conventional teaching devices is the use of elastic rubber and lead, which has a seismic isolation function for the entire transverse direction regardless of the direction of the earthquake, but it is used only for small structures due to its limited amount of shock absorption. Not only does the rubber at the contact surface with lead melt, but it is also difficult to replace.

In addition to the use of elastic rubber and special rubber, which has good durability and seismic isolation function for the entire transverse direction, but also has a problem that the seismic strength is low and difficult to maintain.

In addition, although viscous dampers may be installed between the piers and the top plate to absorb the lateral forces caused by the earthquake, they can only absorb the lateral forces acting in the direction in which the viscous dampers are installed, and they should be installed separately from the support. Therefore, there is a problem that is uneconomical and poor construction.

As related to other teaching apparatus, there is one disclosed in a publication such as Patent Publication No. 2000-0058244, "Shock transfer apparatus", but the structure is complicated and only one side force can be absorbed. If the lateral force acts as a problem that does not at all.

An object of the present invention is to provide a simple device, a support device for the load of the top plate, excellent seismic performance in all directions, and easy maintenance.
