Base plates 4 each having a waterproof sheet 5 pasted on its upper surface are fixed onto adjacent joists 3, and the edges of the adjacent waterproof sheets 5 are overlapped and bonded to each other.

To explain the embodiment in more detail, the frame body 2 has a rectangular frame member 6 made of H steel, as shown in FIGS. If necessary, mark C on the outside of the long side of the gable side corresponding to the verge
It is formed by framing a frame material 7 made of shaped steel. A lower plate 8 such as a gypsum board is fixed to the lower surface of the frame 2, and the inside of the frame 2 is filled with a heat-insulating and sound-absorbing material 9.

The joists 3 are each made of C-shaped steel as shown in FIGS. 4 and 5, and the frame 2
In the illustrated example, a total of six pieces are fixed at equal intervals and positioned on the short side of the plate. Incidentally, reference numeral 10 denotes a gradient adjustment material interposed between each of the joists 3 and the frame 2 as necessary to ensure a water gradient.

In addition, five base plates 4 and 4 are used, each of which is made of a rectangular hard wood cement board, the length of which is equal to the frame 2.
It is approximately equal to the length of the short side of .

The waterproof sheet 5 has a rectangular shape that can cover the base plate 4, and a rectangular shape that can cover the base plate 4. In particular, the width of the waterproof sheet 5 is made larger than the inside of the base plate 4, and the waterproof sheet 5 is attached so as to overhang at least one side of the base plate 4. None. A release paper is pasted to the lower surface of the edge along the longitudinal direction of each waterproof sheet 5 with a certain width via an adhesive, and the part where this release paper is pasted is removed (or the part is pre-applied to the base plate 4). The above-mentioned release paper is bonded to the base plate 4 with the waterproof sheet 5 adhered to the upper surface as described above, with a filler such as butyl rubber interposed between them. After fixing with the paper, it is peeled off and pasted, and the lower surface of the edge along the longitudinal direction of the waterproof sheet 1-5 from which the release paper has been peeled off is exposed to the water flow due to the water gradient, as shown in Fig. 4. It is so arranged that it is adhered to the upper surface of the edge along the longitudinal direction of the waterproof sheet 5 adjacent to the downstream side with respect to the direction, via the adhesive.

In addition, in FIGS. 1 and 2, reference numeral 11 indicates a waterproof cover receiver of a waterproof cover 12 (see FIGS. 3 to 5) that covers the adjacent portion when the roof base panels 1 are laid adjacent to each other. It is a hardware item, and in the roof base panel 1 shown in Fig. 1,
They are fixed in advance at the factory on one of the long sides and on the short side of the ridge, but it is sufficient if they are fixed on the side adjacent to the other roof base panel 1. Also, Figures 1 and 2
The gable side cover holder of the gable side cover 13 (see Fig. 3 and Fig. 5) is not shown in the figure or on the dowel side or ridge side that is not adjacent to other base panels 1. 14 (see FIG. 5) and the ridge side cover holder (not shown) of the ridge side cover 15 (see FIG. 3) may be fixed in advance at the factory. Further, the waterproof cover metal fitting 11, the end cover metal fitting 14, and the ridge side cover metal fitting may be structurally the same in shape and the like so that they can be used in common.

Therefore, when using the roof base panels 1 having the following two configurations, a plurality of them are laid adjacent to each other at the site as shown in FIG. 3, and the adjacent parts of the roof base panels 1 are covered with waterproof covers 12. When the roof base panels 1 are covered with a waterproof cover 12 and the waterproof cover 12 is exposed to form a walkable roof as shown in FIGS. By doing so,
A roof structure with excellent strength and durability as shown in FIGS. 4 and 5 can be formed.

The above-mentioned roof structure will be explained based on FIGS. 3 to 5. The roof base panel 1 is installed and fixed on the building frame such as the outer wall 17, other beams, and partition walls.

Further, the waterproof cover 12 is applied as a joint cover to the adjacent parts of the roof base panels 1 that are laid adjacent to each other, and the covering is applied to the waterproof cover holder of the adjacent roof base panel 1. This is done by holding each of the waterproof covers 11 inside the waterproof cover 12, and screwing the outer surface of the waterproof cover 12 from the roof base panel 1 side. Note that 18 is a support tree located below the upper surface of the waterproof cover 12 and interposed between the waterproof cover 12 and the waterproof cover holder 11.

Furthermore, on the roof base panel 1 laid as described above, in addition to the above-mentioned covering of the waterproof cover 12, other roof base panels 1 are placed on the gable side or on the ridge side that is not adjacent to other roof base panels 1. The gable side cover 13 is covered via the gable side cover holder 14 and the ridge side cover 15 is covered via the ridge side cover holder (not shown), and the waterproof cover 12 and these gable side covers 13 are covered.
, a joining cover 19 is provided at the abutting portion of the ridge side cover 15.
It is covered with. As shown in FIG. 4, on the eaves side of the roof base panel 1, an eave arabesque 20 and an eave gutter 21 are applied, and the eave arabesque 20 is covered with a waterproof sheet 5. Incidentally, such work of covering the eaves with the waterproof sheet 5 can be easily performed by peeling off the release paper on the edge of the eaves of the waterproof sheet 5.

Further, the protective layer 16 may be formed of various covers 12, 13 as described above.
, 15.19 and the above-mentioned eaves treatment work, the upper surface portions of various covers 12, 13, 15, 19 are finally formed in FIGS. 4 and 5. Although these covers 12, 13, 15, 19 may be buried and formed on the roof base panel 1, these covers 12, 13, 15, 19 may be formed by exposing them. In addition, the protective layer to be formed is as follows:
When the roof surface is not a walkable surface but a normal roof surface, the protective layer 16 may be formed of another material instead of the above-mentioned material.

In addition, in FIGS. 4 and 5, 22 is a heat insulating material interposed between the roof base panels 1, and 23 is the roof base panel 1
Decorative covers 24 and 25 that cover the gap from below are a caulking material and a hack-up material interposed between the roof base panel and the outer wall body 17, respectively.

Like gauze, the roof underlayment panels of the present invention can be laid adjacent to each other and then a protective layer corresponding to various finishes can be formed on the top surface to form a roof structure with excellent strength and durability. It is easy to manufacture, inexpensive, etc., and has extremely high advantages.
