PROBLEM TO BE SOLVED: To provide a building structural material that allows a building to be assembled simply with sufficient strength.SOLUTION: A triangular unit 10 includes: (1) two frame materials 20, 30 comprising two side parts 21, 22, 31, 32, of which ends intersect with each other at a right angle, and side parts 23, 33 connecting the other ends of the intersecting side parts; and (2) three column materials 41, 42, 43 each connecting a connection between the two side parts of the two frame materials as necessary. On the two side parts of each of the two frame materials, notches 25, 35 are formed at two positions away from one end and the other end by equal distances w1, w2, the notches being connected to any of the notches formed on the side parts of the other triangular unit 10 using a connector 50.SELECTED DRAWING: Figure 1 |
