Claims

[Claims for Utility Model Registration] (1) In a connection structure in which two structural members are overlapped and friction-bonded by bolts, a plurality of bolt holes are provided between the structural members around the bolt holes on the front and back sides of the plate. , A connection structure for steel structures in which a caul plate with a protruding edge that sinks into the structural member when bolts are tightened is interposed. (2) The connecting structure according to claim 1, wherein the protruding edge of the caul plate is annular surrounding the outer periphery of each bolt hole. (3) The connecting structure according to claim 2, wherein the protruding edge has a shape in which the annular shape is partially removed. (4) The connecting structure according to claim 1, wherein the projecting edge has a grid-like shape as a whole. (5) The connecting structure according to claim 4, wherein the protruding edge has a shape in which a grid-like intersection is omitted.
