Abstract

The present invention includes: an outside plate; first frames each including a first head portion; and second frames each including a second head portion and arranged perpendicular to the first frames. At each of portions where the first frames and the second frames intersect with each other, the second head portion is arranged on the first head portion so as to overlap the first head portion.

First claim

The invention claimed is:

1. A railcar bodyshell comprising:
an outside plate;
first frames arranged at an inner surface of the outside plate and each including
a plate-shaped first head portion having a surface spaced apart from and substantially parallel to the outside plate,
at least one first leg portion extending from the first head portion in a direction substantially perpendicular to the first head portion, and
a first flange continuously formed from the first leg portion and extending substantially parallel to the first head portion; and

second frames arranged perpendicular to the first frames and each including
a plate-shaped second head portion having a surface spaced apart from and substantially parallel to the outside plate, and
an opening portion formed at the second head portion and located above the first flange, wherein:

at each of portions where the first frames and the second frames intersect with each other, the second head portion overlaps the first head portion;
the first flanges of the first frames and the outside plate are joined directly to each other at the opening portions of the second frames, and
longitudinal direction end portions of the second frames are joined to the first leg portions of the first frames.

2. The railcar bodyshell according to claim 1 , wherein:
each of the second frames includes at least one second leg portion extending from the second head portion in a direction substantially perpendicular to the second head portion;
the at least one second leg portion includes a cutout portion at a position where the first frame and the second frame overlap each other; and
the first frames are inserted through the cutout portions of the second frames.

3. The railcar bodyshell according to claim 1 , wherein the second frames are arranged such that surfaces of longitudinal direction end portions of the second head portions of the second frames are flush with surfaces of the first head portions of the first frames.

4. The railcar bodyshell according to claim 1 wherein:
each of the second frames further includes
at least one second leg portion extending from the second head portion in a direction substantially perpendicular to the second head portion, and
a second flange continuously formed from the second leg portion and extending substantially parallel to the second head portion; and

the first frames, the second frames, and the outside plate are joined to one another by spot welding at portions where the first flanges and the second flanges overlap each other.

5. The railcar bodyshell according to claim 1 , wherein the first frames and the second frames are joined to each other by spot welding at portions where the first head portions and the second head portions overlap each other.

6. The railcar bodyshell according to claim 1 , further comprising seat members, wherein:
the first frames are side posts extending in a railcar upper-lower direction;
the second frames are seat receiving members extending in a railcar longitudinal direction; and
the seat members are attached to the second frames.

7. A railcar comprising the railcar bodyshell according to claim 1 .
