DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel used for a building or a wall of a vehicle.

[0002] In this specification, "aluminum" includes an aluminum alloy.

[0003]

2. Description of the Related Art As this kind of panel, there is provided a panel made of a hollow aluminum extruded member having a lengthwise extending partition wall disposed between upper and lower walls, left and right side walls, and left and right side walls, and this hollow aluminum extruded member 2. Description of the Related Art There is known a panel made of a semi-hollow aluminum extruded profile in which a notch extending in a length direction is provided on a lower wall of a panel made of aluminum.

[0004]

The above-mentioned conventional panel has a problem that the bending rigidity in the length direction is strong but the bending rigidity in the width direction is weak.

An object of the present invention is to provide a panel having high bending rigidity in the length direction and high bending rigidity in the width direction.

[0006]

SUMMARY OF THE INVENTION A panel according to the present invention is provided at a position to be reinforced of an extruded aluminum member having upper and lower walls, left and right side walls, and a partition wall extending in a longitudinal direction disposed between the left and right side walls. A vertical wall having a height equal to or slightly smaller than the space between the upper and lower walls and having a width equal to or slightly smaller than the space between adjacent partition walls or the space between the left and right side walls and the adjacent partition walls; A reinforcing member having a pair of tapered opposing walls which are pressed against at least a pair of opposing walls among the upper and lower walls, left and right side walls, and partition walls of the material and narrow toward the vertical wall is fitted.

[0007] A cutout extending in the longitudinal direction may be provided on the lower wall of the extruded aluminum member.

[0008]

In the panel according to the present invention, since the aluminum extruded profile has a partition wall extending in the longitudinal direction, the bending rigidity in the longitudinal direction is strong, and the position of the aluminum extruded profile to be reinforced is required. A vertical wall having a height equal to or slightly smaller than the space between the upper and lower walls and having a width equal to or slightly smaller than the space between the adjacent partition walls or the space between the left and right side walls and the adjacent partition walls, Since a reinforcing member having a pair of tapered opposing walls that are pressed against at least a pair of opposing walls among the upper and lower walls, the left and right side walls, and the partition wall of the extruded profile and narrows toward the vertical wall is fitted, Bending rigidity in the width direction is also strong.
