US 2016/0258161 A1 · Column End Joint Structure

Abstract

In a column end joint structure for joining an end of a column made of flat wooden material having a rectangular cross-section to a joining member, splitting generation at the end of the column is controlled. An expansion of crack is controlled when splitting generated. A cutout portion is provided in each of ends in a longitudinal direction of a column end face, and a joint fitting is coupled inside the cutout portion by a joint bolt. The joint fitting is coupled to a foundation by an anchor bolt. Joint fittings are arranged in the longitudinal direction of the end face inside each cutout portion. One joint fitting is located contacting or close to a surface of the column inside the cutout portion such that the joint fitting side face and the surface of the column inside the cutout portion restrain a displacement orthogonal to the column axis.

A column end joint structure for joining an end of a column made of a flat wooden material having a substantially rectangular cross-section, a length of one side thereof being larger than a length of an adjacent another side, to a joining member which is another member, wherein

a cutout portion is provided in each of both ends in a longitudinal direction of an end face of the column;
a joint fitting is coupled to the column by a joint bolt inserted in an axial direction of the column inside the cutout portion;
the joint fitting is coupled to the joining member;
a plurality of the joint fittings are arranged in the longitudinal direction of the end face of the column inside each of the cutout portions;
and
one of the joint fittings is located at a position in contact with or close to a surface in the axial direction of the column inside the cutout portion such that a side face of the joint fitting and the surface in the axial direction of the column inside the cutout portion restrain a relative displacement in a direction orthogonal to the axis of the column.
