Abstract
A pillar-shaped honeycomb structure having a plurality of cells formed by laminating a plurality of lamination members with a plurality of through holes. The plurality of through holes form the plurality of cells. The lamination members are a substantially disc shaped. A plane portion, a protruding portion, or a cut-out portion is formed on a peripheral side face of the lamination member, or a rod member is inserted in at least one cell of the plurality of cells, where the rod member penetrates from one end to the other end of the cell.
Claims25
A pillar-shaped honeycomb structure comprising a plurality of lamination members laminated together and having a plurality of through holes, the plurality of through holes forming a plurality of cells,
- wherein said plurality of lamination members are substantially disc shaped, and
- wherein:
- said plurality of lamination members have a peripheral side face having a plane portion, a protruding portion, or a cut-out portion, or
- a rod member is inserted in at least one cell of said plurality of cells, said rod member penetrating from one end of the at least one cell to another end of said the at least one cell.
A honeycomb structure comprising:
- a cylindrical lamination body formed by laminating a plurality of lamination members each having a plurality of through holes;
- and
- an insertion member placed in parallel with a longitudinal direction of the cylindrical lamination body so as to divide said cylindrical lamination body,
- wherein said plurality of lamination members have a same divided disc shape as a cross section perpendicular to the longitudinal direction of the cylindrical lamination body that is divided by said insertion member,
- wherein a side face plane portion of said laminated lamination members is placed so as to contact said insertion member, and
- wherein said plurality of through holes are connected to one another to form a plurality of cells.
A casing for an exhaust-gas purifying apparatus used for covering a honeycomb structure formed of a plurality of lamination members, said casing comprising:
- a casing body configured to receive the plurality of lamination members;
- and
- a plane portion, a groove portion, or a protruding portion formed on said casing body at a region where said the plurality of lamination members are laminated.
A method for manufacturing a honeycomb structure, said method comprising:
- laminating a plurality of lamination members so that a plane portion formed on a peripheral side face of said lamination members is mounted on a plane portion formed on a casing;
- laminating a plurality of lamination members so that a protruding portion formed in a peripheral side face of said lamination members is fitted into a groove portion formed in a casing;
- laminating a plurality of lamination members so that a cut-out portion formed in a peripheral side face of said lamination members is fitted to a protruding portion formed in a casing;
- laminating a plurality of lamination members in a manner so as to allow a cut-out filling member to be inserted to fit into a cut-out portions formed in a peripheral side face of said lamination members;
- or
- adjusting a position of through holes by inserting a rod member into at least one of said through holes before or after laminating lamination members.
A method for manufacturing a honeycomb structure, said method comprising:
- laminating lamination members, each lamination member having a same divided disc shape as a cross section of a cylindrical lamination body perpendicular to a longitudinal direction of said cylindrical lamination body divided by a insertion member,
- said lamination members being laminated in a manner as to allow a side face plane portion of said lamination members to contact to said insertion member.
