Abstract
A honeycomb-like core member that can be easily manufactured is disclosed, and a structure using such core member is disclosed. The core member has a plurality of flat plate members (a plurality of first flat plates and a plurality of second flat plates), each of which includes a comb teeth portion that has a plurality of notches, which are open in the long side of a rectangular shape of the flat plate member and extend parallel to the short side of the rectangular shape of the flat plate member. The notches are engaged with each other so that the plate members cross each other, and thus, a plurality of hexagonal-cylinder-shaped first cylinder portions and a plurality of triangular-cylinder-shaped second cylinder portions are formed by the plate members.
Claims13
A core member comprising a plurality of flat plate members, each of said plurality of flat plate members having a rectangular shape, each of said plurality of flat plate members including a comb-teeth portion, the comb-teeth portion being defined by a plurality of notches formed in each of said plurality of flat plate members such that the plurality of notches extend parallel to a short side of the rectangular shape and open to at least one of long sides of the rectangular shape,
- wherein said plurality of notches of the plurality of flat plate members are engaged with each other such that the plurality of flat plate members cross each other and the crossing flat plate members create a plurality of first cylindrical portions each having a hexagonal cylinder shape, and a plurality of second cylindrical portions each having a triangular cylinder shape, and
- wherein a width of each of the notches is set to a value that forms a gap in the vicinity of each of the notches when the flat plate members are engaged with each other.
A method of manufacturing a core member having a plurality of hexagonal-cylinder-shaped first cylindrical portions and a plurality of triangular-cylinder-shaped second cylindrical portions, the method comprising:
- preparing a plurality of flat plate members, each of said plurality of flat plate members having a rectangular shape and including a comb-teeth portion such that the comb-teeth portion has a plurality of notches that are open to at least one of long sides of a rectangular shape and extend parallel to a short side of the rectangular shape;
- and
- engaging the notches with each other such that the plurality of flat plate members cross each other;
- wherein a width of each of the notches is set to a value that forms a gap in the vicinity of each of the notches when the flat plate members are engaged with each other.
