Claims

[Scope of utility model registration request]

A substantially cross-sectional structure having a bottom plate fixed to a lower structure such as a pier, a horizontal support section disposed on the bottom plate, leg sections extending vertically to both ends of the support section, and a fixing section extending to the outside of the leg sections. A downward U-shaped lower shoe, a horizontal support part fixed to a superstructure such as a bridge girder, a leg part extending vertically to both ends of the support part, a fixing part continuous to the outside of the leg part, and the upper and lower surfaces of the support part. an upper shoe having an upwardly U-shaped cross section, and a recess formed in the upper shoe;
An intermediate plate with a sliding material arranged on one surface, which is disposed between the upper shoe, the lower shoe, and the bottom plate, and is housed in a recess on the upper and lower surfaces of the support part of the upper shoe, and an elastic body that biases the intermediate plate. The upper shoe has its support part perpendicular to the support part of the lower shoe between the support part of the lower shoe and the bottom plate, and the entire support part is arranged on the upper surface of the support part of the upper shoe. It is characterized by the fact that the sliding material of the support body, which is placed on the lower surface of the support of the lower shoe and the lower surface of the support of the upper shoe, is placed in sliding contact with the upper surface of the bottom plate.
・Positive and negative reaction force support.
