Abstract:
A method for jointing a plurality of steel members using shear rings, said method comprising the steps of(1) forming bolt holes respectively at plural first steel members and plural second steel members which are overlapped and assembled together; (2) forming at least one annular groove at each of contact surfaces of the first steel members and the second steel members overlapped together, the annular groove of the second steel members having a size capable of tightly receiving a part of the shear ring, and the annular groove of the first steel member having a size capable of receiving the shear ring with a second clearance; (3) forcedly inserting and fixing a part of the shear ring in the annular groove of the second steel member; (4) inserting and then maintaining a remaining part of the shear ring in the annular groove of the first steel member by relatively displacing and approaching the first steel member and the second steel member in a state that the first steel member and the second steel member are overlapped, to thereby align the first steel member and the second steel member; (5) inserting each bolt in each bolt hole of the first steel member and the second steel member; and (6) tightening each bolt inserted in each bolt hole of the first steel member and the second steel member by each nut, so that the shear ring is completely inserted and forced in the annular grooves of the first steel member and the second steel member, to thereby complete jointing of the first steel member and the second steel member by the bolt, the nut and the shear rings.
