されている。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a honeycomb panel made of a metal plate such as stainless steel or titanium. These honeycomb panels are composed of a pair of upper and lower face sheets and a honeycomb core sandwiched between the face sheets. Usually the honeycomb core is corrugated and is fixed to the face sheet by adhesion or other means. The honeycomb panel having such a structure is extremely light and has excellent strength. This type of honeycomb panel is generally used in aircraft, ships, vehicles and the like.

The honeycomb panel 11 includes the honeycomb core 3 between the upper face sheet 2a and the lower face sheet 2b.
It is formed by sandwiching. The honeycomb core 3 is a corrugated plate obtained by subjecting one plate to a large number of grooves.

い。このため図3(B)では溶接欠陥が発生し易い。When assembling the honeycomb panel, the honeycomb core 3 is placed on the lower face sheet 2b, and the bottom surface of the honeycomb core 3 and the face sheet 2b are joined, for example, by welding. 4 is this bottom welding. Next, the upper face sheet 2a is placed, and the top surface of the honeycomb core 3 and the face sheet 2a are joined, for example, by welding. 5 is this top surface welding. However, in FIG. 3 (B), unlike the regular grooves 12 and 14 in the honeycomb core 3, θ is larger than the regular θ 1 by θ 2
When the groove 13 is formed, the top surface of 13 and the upper face sheet 2a do not adhere to each other, so that it is difficult to form the top surface joint 5 in the groove 13. The grooves 13 in which θ is θ 2 are likely to occur at the time of groove processing and the positioning of the bottom surface weld 4 when manufacturing the honeycomb core. Therefore, welding defects are likely to occur in FIG. 3 (B).

However, in this case, the regular grooves 15 and 17 are pressed and deformed, and it is difficult for the top surfaces of the grooves and the upper face sheet 2a to come into contact with each other, so that the top surface joining of 15 and 17 becomes a welding defect. easy.

トの溶接が不良となる可能性が大きかった。According to the present invention, it is possible to manufacture a honeycomb panel without welding defects with high productivity in a simplified manufacturing process. In the conventional honeycomb panel, since the honeycomb core is composed of a single corrugated sheet, a pressing jig is used to secure the adhesion between the honeycomb core and the face sheet when welding the honeycomb core and the face sheet. It is necessary to position the holding jig, which complicates the manufacturing process and causes a problem in productivity. Further, due to the molding state of the honeycomb core, the pressing jig cannot secure the close contact between the face sheet and the honeycomb core, and there is a high possibility that the welding between the honeycomb core and the face sheet will be defective.

It was possible to weld the face sheet without any welding defects.
