PROBLEM TO BE SOLVED: To provide metal fittings which is interposed in a foundation of a wooden building, normally, a connection part between a concrete foundation and a column so as to prevent the connection part from being damaged when an earthquake takes place.SOLUTION: Metal fittings are interposed between a column and a foundation, and fastened with a nut 31 through a disc spring 7 and a support member 11 in a hollow part into which a tip part of an anchor bolt extending from a foundation side is inserted. As the disc spring 7 flexes, the hollow part side is integrated with the column to be tiltable with respect the bolt, and when an earthquake takes place to apply force for tilting to a column side, the column tilts together with the hollow part with respect to the anchor bolt united with a foundation S to allow the column to tilt, thereby stopping a connection part from being damaged.SELECTED DRAWING: Figure 5 |
