曲面連結構造および立体連結構造
Document Type and Number:
Japanese Patent JP6817631
Kind Code:
B2
Abstract:
To provide a curved surface connection structure consisting of units each suppressing unintended deformation.SOLUTION: A unit constituting a curved surface connection structure that is deformed to be a solid connection structure constituting of curved surfaces when a predetermined force acts is connected with an adjacent unit by a beam in a main axis direction when one of opposed diagonals in a regular n-polygon is defined as a main axis, and made into units of three divisions of a first shape unit of which the Poisson ratio in the case of tensile deformation in a direction of the main axis is positive, a second shape unit of which the Poisson ratio is negative, and a third shape unit of which the Poisson ratio value is 0. The unit is connected to both apexes in both ends of a polygonal in parallel with the main axis, and formed so as to include a torsion resistant member of which the rigidity with respect to torsion around the main axis is higher than the rigidity with respect to bending around a sub axis. The unit of at least one division among the units of the three divisions is then used to constitute the curved surface connection structure.SELECTED DRAWING: Figure 1
