Description

  The present invention is a metal sandwich panel that can be used as a building exterior material or the like, and is particularly preferably used as a corner panel of an outer wall.

  Conventionally, a flat metal sandwich panel in which a core material is filled between two metal shells has been proposed. Such a metal sandwich panel is used to form an outer wall by arranging a plurality of such metal sandwich panels vertically and horizontally. In this case, a metal sandwich panel bent into an L shape or the like is used for corner portions such as the protruding corner and the entering corner of the outer wall (see Patent Document 1).

  When manufacturing a metal sandwich panel for a corner, for example, after forming a flat metal sandwich panel, the metal shell and core material on the back side are cut off at a substantially central portion in the lateral direction of the metal sandwich panel. By forming a V-shaped groove over the entire length of the metal sandwich panel in the vertical direction, and then bending the metal sandwich panel at the V-shaped groove portion, a metal sandwich panel for a corner bent into an L shape is formed. can do. As another method, a substantially central portion in the lateral direction of the two metal shells is formed into a V shape or an L shape using a dedicated mold, and then the core material is filled into the two metal shells. Thus, a metal sandwich panel for a corner bent into a V shape or an L shape can be formed.
