Further, as shown in FIG. 3, a rough surface portion 17 is provided on the surface of the attachment portion 15 facing the floor 1 by roughening, and from the attachment portion 15 to the tip of the support portion 16. The dimension L is set to be larger than the width of the gap G, and the support fitting 6 can be inserted and fixed in the gap G under pressure.
[0023]
The support fitting 6 is formed by bending a flat plate having a width of about 5 cm, for example, and a plurality of the support fittings 6 are arranged with a gap in the longitudinal direction of the refractory interlayer material 5. ing.
[0024]
Next, the operation of the present embodiment will be described.
At the time of construction, first, a plurality of support fittings 6 are inserted into the gap G at arbitrary intervals in the longitudinal direction. At this time, since the dimension L from the attachment portion 15 of the support fitting 6 to the tip of the support portion 16 is set to be larger than the width of the gap G, the support fitting 6 is placed in the gap G under pressure. As a result, the rough surface portion 17 is pressed against the outer surface of the iron plate 2. For this reason, the installation stability in the gap | interval G of the support metal fitting 6 can be improved.
