Even when it is displaced from the center of the foundation 1 in the width direction (usually, a steel frame is embedded in the center of the cloth foundation 1 in the width direction, and the anchor bolt 5 is embedded in the center of the cloth foundation 1 in the width direction. Is difficult), Fig. 5
As shown in, the two nuts 6 that make up the double nut 6
One of the nuts a and 6b, which is not screwed to the anchor bolt 5, is positioned on the center line of the base 2, and the long bolt 10 is screwed to the nut 6b. Can be positioned so that the tension that the long bolt 10 exerts on the two horizontal members 2 and 4 is not biased. The two-dot chain line shown in the figure is the center line of the base 2.
