Abstract

PROBLEM TO BE SOLVED: To prevent a lateral member from losing strength by providing a connection member attached to the lateral member and provided with a protrusion comprising a head and a constriction and a notched groove engageable with the protrusion, and further, providing an engaging member fastened to a bolt of the lower structural body. SOLUTION: Notched grooves at both side faces of an engaging member 50 are engaged with a protrusion 43 of a connection member 40 attached to respective confronted floor beams 14, 14. A nut 2A is screwed on an anchor bolt 2 projected from the upper face of the engaging member 50. The engaging member 50 is engaged with the protrusion 43 of first and second connection members 40 attached to the ends of first and second floor beams 14. The engaging member 50 is fastened to the anchor bolt 2 of a foundation 1. Thereby mutually adjoining the first and second floor beams 14 can be connected to the foundation 1. As no bolt insertion hole are formed in the first and second floor beams 14, no anchor bolt 2 protrudes on the upper surface of the first and second floor beams 14.
