PROBLEM TO BE SOLVED: To provide a building construction method for improving rigidity by welding a column and a beam together in an integrated manner. SOLUTION: The deterioration of stress and rigidity due to loss in bolt holes is prevented and stress and rigidity are improved by factory welding a bracket 2 and the beam 3 together. The column 1 and the bracket 2 are welded to each other in a construction site to form a steel construction of high stress and rigidity with the column, the bracket and the beam integrated. Construction- site welding instead of factory welding of the column 1 and the bracket 2 allows smooth loading in a truck and inexpensive and profitable transportation.
