<p>PROBLEM TO BE SOLVED: To facilitate fixing to a hanging bolt, by forming a bolt insertion notch which permits the hanging bolt to be inserted from the side so as to face each side, on both ends of a base plate. SOLUTION: A supporting material 11 is formed out of a base plate 12 and a pair of right and left side plates 13 so as to form a roughly U-shaped and constant cross-sectional channel. An elongated bolt insertion notches 14 facing the side are formed at both end parts of the base plate 12, and a plurality of engaging holes 15 are drilled along the bolt insertion notches 14 at prescribed intervals. A hanging bolt 7 is inserted into the bolt insertion notch 14 of the base plate 12, nuts 8 at the upper and lower parts of the hanging bolt 7 are tightened, the base plate 12 is clamped by the upper washer 21 and lower washer 22, and the supporting material 11 is installed on the right and left hanging bolts 7. It is thus possible to install the supporting material 11 easily and safely even at an overhead location.</p> |
