The left and right guide rails 1, the flame-retardant fire-resistant sheet member 14, the flame-retardant flooring member 20, and the cover member 35 have fire resistance that is strong against heat of fire and hard to burn.

Next, the operation of the above embodiment will be described.

The contact portion 26 of the first landing member 21, ie, the holding surface 27, and the contact portion 32 of the second landing member 22, ie, the holding surface 33, are positioned near the retaining projection 16. A first landing member for holding the flame-retardant refractory sheet body 14 in opposition.
Attachment piece 31 of second landing member 22 to the inside of vertical plate 25 of 21
The first landing member 21 is fixed by attaching the mounting piece 31 to the inner side of the vertical plate 25 with a plurality of bolts 23.
The second flooring member 22 is fixed to the lower surface of the base member, so that the flame-retardant flooring body 20 is securely attached to the lower end of the flame-retardant fire-resistant sheet member 14.

The holding surface 27 of the first landing member 21 and the holding surface 33 of the second landing member 22 are positioned near the retaining ridge 16, that is, the retaining ridge 16. And the flame-retardant refractory sheet body 14 is located at a continuous portion of the flame-retardant refractory sheet body 14
Are pinched from both sides, so that both pinching surfaces 27,
A retaining ridge 16 that protrudes larger than the distance between the two holding surfaces 27 and 33 is provided below the space between the retaining surfaces 33, and the lower end of the flame-retardant fire-resistant sheet body 14 is flame-retarded by the retaining ridge 16. The non-flammable landing body 20 is securely attached and prevented from falling off, so that the flame-retardant landing body 20 is prevented from falling off.

That is, since the second landing member 22 is fixed to the first landing member 21, the flame-retardant refractory sheet 14
Is inserted through a slit 58 formed by the holding surface 27 of the first landing member 21 and the holding surface 33 of the second landing member 22 at an interval smaller than the thickness of the retaining projection 16 and This slit
The second landing member 22 is fixed to the first landing member 21 while being clamped at 58, and the retaining ridge 16 abuts against the opening edges of the two clamping surfaces 27 and 33 to prevent it from falling off. Thus, the flame-retardant landing body 20 is prevented from falling off from the lower end of the flame-retardant fire-resistant sheet 14.

The abutting portion 26 of the first landing member 21, that is, the holding surface 27, and the abutting portion 32 of the second landing member 22, that is, the holding surface 33, both sides of the fire-resistant fire-resistant sheet 14.
