Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hollow panel used as a structural material for ships and buildings.

In this specification, “aluminum” includes an aluminum alloy.

[0003]

[Prior art]

 A hollow panel including a first facing wall portion and a second facing wall portion that face each other at a predetermined interval and a plurality of connecting wall portions that connect the facing wall portions to each other has been conventionally known. Traditional hollow panels are made from extruded aluminum profiles that are extruded together.

[0004]

[Problems to be solved by the device]

 In the conventional hollow panel, the inner surface of the panel may be corroded, but it has been difficult to apply a surface treatment such as painting or anodizing to the inner surface of the panel to improve the corrosion resistance. Further, it is difficult to obtain a hollow panel having two different advantages such as excellent corrosion resistance and good extrudability.

Therefore, it is conceivable to separately prepare two types of extruded profiles, subject them to a surface treatment, and then bond them by welding to obtain a hollow panel. However, this is due to the heat during welding. In addition, there was a problem that the strength near the weld became weaker and the surface treatment deteriorated.

An object of the present invention is to provide a hollow panel in which two types of extruded profiles are joined without welding.
