JOINT STRUCTURE OF VERTICAL MEMBER AND HORIZONTAL MEMBER, METHOD FOR NONDESTRUCTIVE INSPECTION OF JOINT CONDITION OF VERTICAL MEMBER AND HORIZONTAL MEMBER, BUILDING UNIT, AND JOINT STRUCTURE BETWEEN BUILDING UNITS

摘要

PROBLEM TO BE SOLVED: To provide a joint structure of a vertical member and a horizontal member reducing thermal deformation due to welding. SOLUTION: A vertical frame 6 is provided with a first vertical frame plate piece 61 parallel with the longitudinal direction of the vertical frame 6 and a second vertical frame plate piece 62 parallel with the longitudinal direction of the vertical frame 6 and in the direction in which it crosses the first vertical frame plate piece 61 orthogonally. A horizontal sash bar is provided with a first horizontal sash bar plate piece 41 parallel with the longitudinal direction of the horizontal sash bar 4 and a second horizontal sash bar plate piece parallel with the longitudinal direction of the horizontal sash bar 4 and in the direction in which it crosses the first horizontal sash bar plate piece orthogonally. The first vertical frame plate piece 61 opposes to the first horizontal sash bar plate piece 41 on their faces through the second horizontal sash bar plate piece 42, and the second vertical frame plate piece 62 crosses both of the first horizontal sash bar plate piece 41 and the second horizontal sash bar plate piece 42 orthogonally. An end fringe in the longitudinal direction of the horizontal sash bar 4 is joined with the first vertical frame plate piece 61 so as to abut on it, and an end part along the longitudinal direction of the horizontal sash bar 4 is joined with the second vertical frame plate piece 62 so as to abut on it. Joining is performed by fillet welding, respectively.
