Document Type and Number:
Japanese Patent JP2023156703
Kind Code:
A
Abstract:
To provide a joint structure that solves problems such as processing labor for removing protrusions and an increase in the number of bolts when connecting H-section steel with protrusions in which protrusions are formed in a predetermined uneven pattern on at least the outer surface of a flange.SOLUTION: An outer attachment plate 7 and inner attachment plates 8 and 8 are provided on outer and inner surfaces of flanges 3 and 5, respectively, so as to straddle joint ends 2a of H-section steel 2 with protrusions. At a mating surface of the outer attachment plate 7 to the outer surface of the flange, a protrusion 11 is formed with a concave-convex pattern having a convex part 11a that comes into contact with a concave part 6c on the flanges 3 and 5 side, and a concave part 11b that comes into contact with convex parts 6a and 6b on the flange side. The outer attachment plate 7, the flange 3 (5), and the inner attachment plate 8 are integrally fastened with a plurality of high-strength bolts 9 and nuts 10.SELECTED DRAWING: Figure 6
