Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel used for walls of buildings and vehicles.

In this specification, "aluminum" includes an aluminum alloy.

[0003]

2. Description of the Related Art As a panel of this kind, a panel made of a hollow aluminum extruded profile having upper and lower walls, left and right side walls, and partition walls extending in the longitudinal direction, and the hollow aluminum extruded profile. A semi-hollow aluminum extruded profile panel is known in which a lower wall of the panel is provided with a notch extending in the lengthwise direction.

[0004]

The above 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 which has a high bending rigidity in the length direction and a high bending rigidity in the width direction.

[0006]

A panel according to the present invention is provided at a position to be reinforced by an aluminum extruded profile having upper and lower walls, left and right side walls, and a partition wall extending in the lengthwise direction between the 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 the adjacent partition walls or the space between the left and right side walls and the partition walls adjacent to the left and right side walls; A reinforcing member having a pair of tapered opposing walls that are pressed against at least a pair of opposing walls of the upper and lower walls, left and right sidewalls, and partition walls of the material and narrow toward the vertical wall is fitted.

A cutout extending in the length direction may be provided on the lower wall of the aluminum extruded profile.

[0008]

In the panel according to the present invention, since the aluminum extruded profile has a partition wall extending in the lengthwise direction, the bending rigidity in the lengthwise direction is strong and the aluminum extruded profile should be reinforced at the position to be reinforced. 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 left and right side walls and the space between the adjacent partition walls, Since the upper and lower walls of the extruded profile, the left and right side walls, and the partition wall, the reinforcing member is fitted into at least a pair of opposing walls that are pressed into contact with each other and that narrows toward the vertical wall. The bending rigidity in the width direction is also strong.
