A face plate 16 that covers the upper cross member 17 and the outer base material 18 is fixed to the upper cross member 17.

In the second embodiment configured as described above, the base material has two layers, hard and soft, inside and outside, and the cross members have two layers, upper and lower, so the roof thickness is thinner than that of the first embodiment. Although the soundproofing and heat insulation effects are inferior to those of the first embodiment, they are superior to those of a conventional roof having the same thickness as those of the second embodiment, and the fire resistance is almost the same as that of the first embodiment.

FIG. 4 shows a third embodiment. In FIG. 4, the same reference numerals as in the second embodiment indicate the same members, and 19 is an inner layer base material made of the same material as the inner layer base materials of the first and second embodiments. The inner layer base material 19 is laid on top of the adjoining one with its opposite end abutted, and a notch 19a is formed inside the structure, that is, at the bottom, and a thin steel plate with a substantially inverted groove cross section is formed over these. The lower cross member 20 (see FIG. 6), which is the formed joint member, is fitted, and the lower cross member 20 is supported on the support member 1. Upper cross members 17 similar to those of the second embodiment and upper cross members 21 having a substantially W-shaped cross section (see FIG. 9) are alternately arranged on the inner layer base material 19, and these are attached to the support member 1. It is supported by long bolts 7 and nuts 8. Note that the configuration of the third embodiment other than those described above is the same as that of the second embodiment.

The roof of the third embodiment configured as described above is
Almost the same effects as those of the second embodiment can be obtained.

In addition, in the present invention, the lower cross member that also serves as a joint member can be a hat-shaped steel material shown in FIGS. It is also possible to use a thin steel plate formed by modifying the notch shape of the base material to have an inverted V-shaped cross section as shown in FIG. The cross section shown in FIG. 9 can be replaced with the one having a substantially W-shaped cross section as shown in FIG. 9 as appropriate for each embodiment, and the one shown in FIG. 9 can also be used as a middle and lower cross member. In addition to the above, it is also possible to form cross members as shown in FIGS. 10 and 11 and use them as cross members for each of the upper and lower stages.

In addition, in the present invention, the inner layer, intermediate layer, and outer layer base material do not necessarily have to be made of the materials and arranged as in the first to third embodiments.
The intermediate layer of the base material is hard, and the inner and outer layers are soft, and the inner layer base material is a laminated product with the lower and upper layers consisting of fine wood wool and Portland cement, thick wood wool and Portland cement, and wood wool and cement. The blending ratio may be adjusted so that the amount of cement in the upper portion decreases.

The present invention uses an upper cross member made of a steel material with a stepped hat-shaped cross section in place of the middle cross member and upper cross member of the first embodiment, and has an intermediate layer base material on the flange and an outer layer on the step part.
