may be left as is, and the threaded rod 4b protruding from the top of the nut 12 is passed through the mounting hole 5a of the bottom 5 of the intermediate support piece B, and a new nut 12 is tightened and fixed. (see figure).

Furthermore, as shown in FIG. 6, a lower folded roof plate A is provided.

A new nut 12 is installed on top of the nut 12 that fixes the bracket to the receiving bracket 4, and the bottom part 5 of the intermediate support bracket piece B is placed on this new nut 12. The metal fitting piece B may also be fixed. In this case, with the second new nut 12 from the bottom, the height of the intermediate support piece B can be adjusted in the vertical direction within the length range of the screw rod 4b.

In this way, the chevron portion 2゜2 of the lower folded plate roof A...
- The upper folded roof plates C+ and C+ are placed on the intermediate support metal fitting pieces B, B, ... which are fixed on top. First, the intermediate support piece B is located on the lower surface side of the fitting chevron portion 9, and the fitting portion 10.10 is the fitted portion 7a, 7 of the intermediate support piece B.
The lower folded roof panels C, , C are fitted into a and are also adjacent to each other.
The fitting chevron portions 9°9 of , are overlapped to connect the upper folded plate roof temporary C, , C, and the lower folded plate roof C is roofed, and the chevron portion 2 and the upper part of the lower folded plate roof are roofed. A double folded plate roof is constructed with the fitting chevron portion 9 of the folded plate roof C in the same longitudinal direction.

〔Effect of the invention〕

In the present invention, fitting portions 7a are provided on the left and right sides of the bottom portion 50 in which the mounting holes 5a are formed at both ends in the front and back direction.

An intermediate support metal piece B having a relatively low height and having a trapezoidal chevron portion 7 formed as 7a is inserted into a screw rod 4b protruding above the chevron portion 2 of the lower folded plate roof A and fixed with a nut 12. The fitting portion 10 of the upper folded plate layer IIC, which has fitting chevron portions 9 forming fitting portions 10.10 facing each other on the main plate 8, is fitted into the fitted portion 7a of the intermediate support piece B, and the lower portion By forming a double folded plate roof in which the chevron portion 2 of the folded plate roof C and the fitting chevron portion 9 of the lower folded plate roof A are roofed in the same longitudinal direction, first of all, construction can be made simple and quick. , Second, the lower folded plate roof A
The vertical distance between the upper folded plate roof C and the upper folded plate roof C can be made extremely small, resulting in various effects.

To explain these effects in detail, first, by providing the mounting through hole 5a in the bottom part 5 of the intermediate support piece B in advance,
The chevron portion 2 of the lower folded plate roof A is inserted into the mounting through hole 5a of the bottom portion 5.
The intermediate support piece B can be installed by simply passing through the upwardly protruding screw rod 4b and tightening the nut 12. At the time of installation, the lower folded plate roof A is fixed with the screw rod 4b of the receiving metal fitting 4. Although the nut 12 for this purpose is tightened, as long as the threaded rod 4b protrudes slightly from the nut 12, the intermediate support piece B can be installed, and the nut 12 is not required. , it is also possible to fix the intermediate support fitting piece B.

Further, the intermediate support fitting piece B is directly fixed onto the chevron portion 2 of the lower folded plate roof A, and is attached to the chevron portion 2,
．． ...There is no need for an intermediate purlin to be erected above, and there is an advantage that the number of parts can be reduced compared to the conventional method, making the construction easier and faster, and by extension, the weight of the roof can be reduced.

Further, the trapezoidal chevron portions 7.7 formed symmetrically from both ends of the bottom portion 5 in the front-rear direction are fitted perpendicularly to the longitudinal direction of the fitting chevron portion 9 of the upper folded plate roof C. When fitted, the trapezoidal chevron portion 7 hardly shrinks in the width direction, so the upper folded plate roof C is extremely difficult to separate from the intermediate support piece B and is firmly fixed.

Moreover, by making the chevron part 2 of the lower folded plate roof A and the fitting chevron part 9 of the upper folded plate roof C in the same longitudinal direction, and by attaching the intermediate support piece B on the chevron part 2 of the lower folded plate roof A. , the upper folded plate roof C is placed directly above the chevron part 2 of the lower folded plate roof A.
The fitting chevron portions 9 can be arranged so as to substantially overlap each other. In this way, attach the intermediate support piece B to the lower folded plate roof A.
Since the structure is such that the upper folded plate roof C is directly fixed onto the chevron portion 2 of the roof and the upper folded plate roof C is roofed on the intermediate support piece B, the lower folded plate roof A is attached to the chevron portions 2, 2, unlike the conventional structure.゜Compared to the type in which a structural member such as an intermediate purlin is erected on the structural member and metal fittings are fixed at predetermined intervals on the structural member to form the upper folded plate roof C, the lower folded plate roof C is The distance between the roof A and the upper folded plate roof C can be made extremely small.

In this way, by reducing the distance between the lower folded plate roof A and the lower folded plate roof C, it is possible to fill the gap between the lower folded plate roof A and the upper folded plate roof C with a soft heat insulating material such as a sheet of glass wool. Even if the double folded plate roof is internally installed, it can be closely attached to the lower folded plate roof A and the upper folded plate roof C, and a double folded plate roof having good heat insulation performance can be provided.

Furthermore, if the lower folded plate roof A is an existing one and is provided with a lighting window part a and a ventilation part, the lower folded plate roof A
Since the distance between the upper folded plate layer lIC and the upper folded plate layer lIC can be made smaller, the lighting window part can be made smaller by making slight modifications such as providing openings in the main plate 8 of the upper folded plate layer mC at locations corresponding to the lighting window part a and the ventilation part A. a,
By making the ventilation part protrude from the opening, it becomes possible to use the existing lighting window part a and ventilation part, and there is no need to newly install the lighting window part a and ventilation part as shown in Figure 8. It is something.
