The lower suspension member 2b is straddled so as to be located at 29. Further, a retaining piece 29a is provided inside the groove 29, and the retaining pieces 39a prevent the side edges of the gutter member 3 from coming off.

Further, the width of the gutter member 3 is made slightly larger than the width between the both sandwiched portions 11 of the roof plate 1 facing each other at the joint portion, so that rainwater dripping from the both sandwiched portions 11 can be reliably secured. I am able to receive it. The gutter member 3 may be resin-molded.

Next, the construction process of the vertical roof structure constructed as described above will be explained. Based on the marking of the upper surface of the base material a, a long gutter member 3 is arranged along the flow direction at a position directly below the joint of the roof plate 1, and a predetermined gutter member 3 is provided along the gutter member 3. A certain number of suspension members 2 with a space between them
Is provided and fixed to the base material a. The above-mentioned base material a is a steel frame, a concrete panel such as ALC,
It refers to all the strength structures and members on the side of the building body, such as wood chips and cement boards, and also includes those with a heat insulating material interposed in the middle. Further, in order to attach and fix the lower suspension member 2b to the upper surface of the base material a as described above, when the base material a is wood, nails or wood screws are used as described above, but the material of the base material a is ceramic. In the case of the system, a tapping screw is used, and in the case of the steel system, a drill screw is used as described above.

Next, a base material b such as a heat insulating material is placed on the base material a on both sides of each of the lower suspension members 2b described above, and the roof plate 1 is laid on the base material b. In the case of the embodiment shown in FIG. 1, a foamed polyethylene sheet c is provided on the back surface of the roof plate 1.
Is attached. In the roof plate 1 laid on the field material b, the inner bent portions of the folded portions 12 at the side edge portions are fitted and locked to the projecting edge pieces 26 that sandwich the openings of the lower suspension members 2b. In this state, the sandwiched portion 11 is placed on the bottom surface in each lower suspension member 2b.

In the above state, the engagement strength can be obtained by engaging the projecting edge piece 26 of the lower hanger 2b with the inside of the folding portion 12 of the roof plate 1. Therefore, in the state before attaching the upper suspension member 2a, the lower suspension member 2
Since b and the roof plate 1 can be held by the above-mentioned engagement strength, there is no concern that the roof plate 1 will be scattered by the wind during construction.

When the side edge portions of the two adjacent roof plates 1 are fitted to the lower suspension members 2b, the elastic pieces of the upper suspension members 2a fit into the engaging recesses 28 of the lower suspension members 2b. 21 is fitted and the fixed locking portion 22 at the lower end of the piece 21 is locked to the fixed locking piece 28a in the engaging recess 28.

As a result, the side edge portions of the adjacent roof plates 1 are joined to each other via the suspension members 2.

Next, the cover member 4 is fitted on the upper surface of each upper suspension member 2a and fitted into the opening of the joint. Upper suspension member 2
In the state where a is engaged, the locked piece 13 at the tip of the clamped portion 11 and the retaining locking portion 23 at the tip of the clamp piece 24 face each other with a slight gap. For example, when the roof plate 1 is pulled up by wind pressure, the locked piece 13
Slides outward and engages with the retaining lock 23, preventing the sandwiched portion 11 from slipping out between the sandwiching piece 24 and the inner bottom surface of the lower suspension member 2b.

Therefore, the adjacent roof plates 1 are locked by the clamping force with respect to the clamped portion 11 and the locking force of the folding portion 12, and the retaining locking portion 23 and the locked piece 1 are retained.
Since the sandwiched portion 11 is prevented from coming off by the engagement with 3, the engaging strength at the joint portion of the roof plate 1 is very high, and the wind pressure resistance strength of the roof can be improved.

FIG. 2 shows a modification of the roof structure shown in FIG.

[0032]

Since the present invention is configured as described above, it has the following effects. (1) By sandwiching the sandwiched portion of the roof plate side edge portion between the sandwiching portion of the upper suspension member and the inner bottom surface of the lower suspension member, the side edge portions of adjacent roof plates are joined together. Therefore, stable engagement strength can be obtained between the roof plate side edge portion and the suspension member, and the engagement by the suspension member can be reliably performed even if the roof plate is deformed such as twisted. it can.

(2) The clamped portion provided on the clamped portion of the roof plate is locked to the lock portion of the upper suspension member so that the clamped portion of the roof plate clamps the upper suspension member. Since it is prevented from coming out from between the inner bottom surface of the lower suspension member and the lower suspension member, even when a negative pressure is applied to the roof plate, the upper suspension member clamping portion and the lower suspension member inner bottom surface are clamped. The roof plate does not come out from between. Thereby, the wind pressure resistance strength of the roof can be improved.

(3) In the case where the side edges on both sides of the lower suspension opening are engaged with the inside of the folded portion on the side edge of the roof plate, the projecting edge of the lower suspension is the roof. Engagement strength can be obtained by engaging the inside of the folded portion of the plate. Therefore, since the lower suspension member and the roof plate are held by the above-mentioned engagement strength during the construction before the attachment of the upper suspension member, it is possible to prevent the roof plate from being scattered by the wind. Further, after the upper suspension member is attached, the roof plate is engaged with the sandwiched portion and the folded-down portion at two locations, so that the engagement strength can be further improved.
