PURPOSE:To easily and effectively perform the transportation and setting of the parts of sheathing strut by providing a coupler having a coupling face to couple the part end formed in the same shape as the tip end of the vertical portion on the same face side as the vertical portion in the tip portion of the cross part. CONSTITUTION:A strut 1 is made up of a cross part 3 integrally set with a vertical part 5 at an angle more than right angle but smaller than planar angle mutually. On the basal end of the cross part 3, a coupler 7 having a coupling face 6 to couple the part ends formed in the same shape as the tip face 2 of the cross part 3 is provided on the opposite side of the vertical part 5. Also, at the tip of the cross part 3, a coupler 9 having a coupling face 8 to couple the part ends formed in the same shape as the tip 4 of the vertical part 5 is provided on the same face side of the vertical part 5. By this, the production of the sheathing strut is made easier and the transportation and setting of the strut can be attained easily and effectively. |
