<p>PURPOSE:To reduce the man-hours necessary for work by using a jig provided with a magnet, and by supporting a fire-proof covering member temporarily. CONSTITUTION:In a state that a fire-proof covering member A is mounted on a jig B composed of magnets 11 fitted at both the ends of an aggregate 10, they are butted to the lower surface of a structural body. By this butted state, the magnets 11 at the external side ends are attracted to the side of the structural body, and so the fire-proof covering member A can be temporarily supported on the structural body via the jig B with the magnets. In this temporarily supported state, a welding pin is inserted into the fire-proof covering member A, and by welding with a welding gun, the fire-proof covering member A is fixed on the structural body.</p> |
