Claims

[Scope of Claim for Utility Model Registration] (1) At the joint between the column body of a wide window column of a large bus and a cross beam made of square pipe material, stepped recesses are provided on the outer surface of the column body and the outer surface of the end of the cross beam, respectively. A gusset made of a flat plate material having a shape and thickness to be fitted and joined into the double stepped recesses is applied from the outside to the double stepped recesses, and the gusset and the stepped recess of the pillar body are spot-spotted. The side structure is fixed by welding, the gusset and the stepped recess of the cross beam are fixed by plug welding, and the lower end of the stepped recess of the cross beam and the gusset are fixed by bead welding. A connection structure between the column body and the cross beam in a large bus body with a skeleton structure. (2) In the structure according to claim (1), the stepped recess on the outer surface of the cross beam end is formed from a position that is a predetermined dimension below the upper end of the outer surface of the cross beam end, and extends to the lower end. A connecting structure between a column main body and a cross beam in a large bus body having a side structure skeleton structure, characterized in that the corner portion of the stepped recess has a diagonally cut shape. (3) A large bus having a side skeleton structure according to claim (1) or (2), characterized in that the upper end of the stepped recess of the cross beam and the gusset are fixed by bead welding. A joint structure between the column body and the cross beam in a car body.
