Joining member and framework structure

A framework structure constructed by joining tubular members as angular pipes to each other by using a joining member comprising a first joining member, a second joining member, and a securing member,

• wherein the first joining member comprises:
• a rectangular-parallelepipedo or cubical angular-pipe-like angular tube section;
• a pair of first insertion segments extending from each of at least two side surfaces of four side surfaces parallel to a Z direction as an axial direction of the angular tube section, the pair of first insertion segments extending in an X direction or a Y direction orthogonal to the Z direction from positions located inward by a predetermined distance relative to a pair of side edges, extending in the Z direction, of each of the at least two side surfaces;
• and
• a securing slit that passes in a thickness direction through each of an opposing pair of the side surfaces of the angular tube section and to which the securing member is inserted,
• wherein the second joining member comprises:
• a square or rectangular planar portion;
• a pair of second insertion segments extending perpendicularly from the planar portion respectively along a pair of side edges of one of surfaces of the planar portion;
• a pair of linkage insertion segments extending perpendicularly from the planar portion respectively along the pair of side edges of a surface opposite the surface of the planar portion from which the second insertion segments extend, the pair of linkage insertion segments being inserted in the angular tube section;
• and
• a securing member retainer provided between the pair of linkage insertion segments and for retaining the securing member therein,
• wherein the second joining member is secured to the first joining member as a result of the pair of linkage insertion segments being inserted in the angular tube section and the securing member inserted in the securing slit being retained by the securing member retainer, and
• wherein a plurality of the tubular members are connected to each other as a result of the pair of first insertion segments and the pair of second insertion segments being inserted into ends of the tubular members that are different from each other.
