As shown in FIG. 3, one obtained by joining two hexagon nuts using appropriate means such as welding is used. Further, as shown in the figure, it is preferable that the height of one nut is higher than that of the other nut, and the height of the double nut 6 is increased by configuring the double nut 6 in this manner. In the same manner as a normal hexagon nut is screwed to a part with a wrench, a wrench can be engaged and screwed from six directions, or an eyeglass wrench or a box wrench can be engaged and screwed.

Even when the base 1 is shifted from the center in the width direction (normally, a steel frame is buried in the center in the width direction of the cloth base 1, and the anchor bolt 5 is buried in the center in the width direction of the cloth base 1. Is difficult), FIG. 5
As shown in the figure, two nuts 6 constituting the double nut 6
The nut 6b, which is not screwed to the anchor bolt 5 among the nuts 6a and 6b, is positioned on the center line of the base 2, and the long bolt 10 is screwed to the nut 6b, so that the long bolt 10 is positioned on the center line of the base 2. Can be positioned so that the tension exerted by the long bolt 10 on the two cross members 2 and 4 is not biased. The two-dot chain line shown in the figure is the center line of the base 2.

Therefore, in the present invention, a plurality of short bolts 8 provided with thread grooves at both ends thereof are longer than at least the ceiling height using a long nut 9 or a turnbuckle or the like so as to facilitate the handling. The bolts connected in such a manner can be used as the long bolt 10.
