At this time, the side end portion 3b of the main body portion 3 of one adjacent ridge plate 2 is adjacent to the side end portion 4b of the cap portion 4 of the other adjacent ridge plate 2 and one side surface of the mountain portion 6 of the folded plate roofing material 1. 6a, the adjacent ridge plates 2, 2 can be connected without any gap.

As described above, the cap portion 4 of the ridge plate 2 is fitted and fixed to the mountain portion 6 of the folded-plate roofing material 1 by a fitting method, so that the cap portion 4 of the ridge plate 2 is only pressed down from above. The slab 2 can be fixed between the ridge-side end portions 1a of the folded roof material 1. In addition, since it is not necessary to fasten bolts during the construction, the work procedure is simplified, speedy construction can be realized, and bolts and screws can be realized. The cost can be reduced by omitting the above.

Further, by integrating the main body portion 3 and the cap portion 4, only one ridge plate 2 is required for one unit (one valley portion 5 and one ridge portion 6) of the folded-plate roofing material 1; The required number of parts is reduced to one. Accordingly, not only the construction is facilitated, but also the ridge plate 2 is easily accommodated, and the strength of the ridge plate 2 itself is enhanced by integrating the body portion 3 and the cap portion 4 having different shapes. In addition, ribs 7a to 7c are formed in the center of the main body 3 and the cap 4, and the ribs 7a to 7c are formed.
and both sides 3 of the main body 3 and the cap 4 around the center c.
Since b and 4b are each bent obliquely downward, the strength of the ridge plate 2 itself is increased even when the central portion of the main body portion 3 and the cap portion 4 is not supported from below by the folded roof material 1. Therefore, it is possible to provide the ridge plate 2 having excellent load resistance and durability. Moreover, ribs 7a to 7a are provided at the center of the main body 3 and the cap 4.

Can function as a reinforcement, and can further improve the durability of the ridge plate 2.
The ribs a to 7c also have a draining function, and even when the inclination of the roof is small and the inclination of the main body portion 3 and the cap portion 4 are small, the drainage on the ridge plate 2 is improved by the ribs 7.

Further, since the ridge plate 2 is fixed without using bolts, the bolt heads are not exposed on the surface of the ridge plate 2, so that the appearance of the roof is improved and rainwater enters through the bolt holes and the like. It is possible to eliminate the possibility of corrosion due to the occurrence of corrosion, so that it is possible to provide an excellent weathering effect. In addition, a plurality of sealing tapes 12 are provided on the back surface of the ridge plate 2 along the direction B parallel to the ridge A. Can increase the bonding strength between the ridge plate 2 and the folded roof material 1 and at the same time,
It is possible to reliably prevent rainwater from flowing into the gap G between the folded sheet roof material 1 from the gap between the sheet material and the folded sheet roof material 1 with the sealing tape 12, and the waterproof property can be further enhanced.

Further, between the plurality of ridge plates 2, the side end 3 b of the main body 3 of one adjacent ridge plate 2 is folded with the side end 4 b of the cap portion 4 of the other adjacent ridge plate 2. Since the ridgeboards 2 are connected to each other so as to be sandwiched between the ridges 6 of the shingle roofing material 1, rain leakage between the ridgeboards 2 and 2 can be reliably prevented, and the cap portion 4 is fitted. By the fitting force between the fitting projection 9 and the fitting recess 8 of the folded-plate roofing material 1, the tight contact between the cap part 4, the main body part 3, and the ridge part 6 is maintained, so that bolts and screws are not used. Since the plurality of ridge plates 2 and 2 can be connected to each other and the ridge plates 2 and 2 have a continuous shape, the entire roof has an external appearance as an integral object, and the design is more excellent. It will be.

On the other hand, when the building is dismantled, the ridge plate 2 is fixed to the folded roof material 1 by fitting without using bolts, so that the ridge plate 2 can be easily removed and the dismantling operation is easy. For example, in a short-term building or the like, the ridge plate 2 can be repeatedly reused, and there is an advantage that waste of resources can be eliminated. In addition,
In the above-described embodiment, the case where a plurality of valleys 5 and a plurality of ridges 6 are alternately formed to form one folded plate roofing material 1 is shown. However, as shown in FIG. 7, for example, as shown in FIG. 7, the crest 6B of the other folded plate roof material 1B is fitted on the upper surface of the crest 6A of the other folded plate roof material 1A, and the other folded plate roof material 1B is further fitted. The cap portion 4 of the ridge plate 2 of the present invention may be fitted to the upper surface of the mountain portion 6B of the shingle 1B. In this case, the ridge portion 6B of the other folded plate roof material 1B and the cap portion 4 of the ridge plate 2 are sequentially placed on the ridge portion 6A of one folded plate roof material 1A, and the cap portion 4 is pressed from above. The fitting recess 8
A, 8B and the fitting projection 9 are fitted to each other to connect the folded roof materials 1A, 1B, and to make the folded roof material 1B and the ridge plate 2
Can be easily and reliably connected to
It is possible to further reduce construction.

The ridge plate 2 of the present invention can be manufactured by press molding using a metal mold. However, in order to increase its strength, it can be manufactured by casting or forging, for example. Further, instead of forming the plurality of ridge boards 2 as separate bodies, the ridge board 2 is formed of a plate body having substantially the same length as the folded roof material 1 (different from the length L in FIG. 1). Body part 3 on body
Alternatively, a plurality of cap members 4 may be formed alternately. In this case, the number of components of the ridge plate 2 can be reduced and the construction of the ridge plate 2 can be further simplified.
