Is done. The face door opening 37 is located below the eaves side end of the corresponding convex portion 22. The face door opening 37 communicates with the ventilation space 23 formed in the corresponding convex portion 22. Thereby, outside air is introduced into the ventilation space 23 via the corresponding door opening 37. That is, the face door opening 37 functions as a vent for introducing outside air into the vent space 23. Although illustration is omitted, the ridge side end portion of each convex portion 22 is opened, so that the outside air introduced into each ventilation space 13 is discharged from the ridge side. Further, in the plate-like portion 31 of the face door 3, the face door opening 37 is not formed in the portion corresponding to the bottom face portion 21 of the uneven roof material 2, and the plate-like portion 31 has the corresponding bottom face portion 21. Support from below.

  Furthermore, the roof structure includes a connecting member 4 that connects the plate-like portion 31 and the closing portion 32. The connecting member 4 may be a plate-like member, or may be a hollow tubular member having a circular cross section or a rectangular cross section or a solid columnar member except that both ends are processed into a flat plate shape.

  As shown in FIG. 3, the connecting member 4 is arranged so as to span the notch 34 of the rising piece 33, and one end is fixed to the ridge side surface 32 a of the closing part 32. The other end is fixed to the plate-like portion 31.

  The connecting member 4 may be integrally formed with the plate-like portion 31 and the closing portion, or may be formed as a separate body from the plate-like portion 31 and the closing portion 32 and adhered to the plate-like portion 31 and the closing portion 32. The fixing tool 9 may be used for fixing. From the viewpoint of restraining the closure part 32 from falling to the eaves side due to the load of snow and suppressing deformation, the connecting member 4 is formed separately from the plate-like part 31 and the closure part 32, and the plate-like part 31 and the closure part are formed. It is preferable to adhere and fix to 32. Further, when the connecting member 4 is made of metal, the fixing method for the closing portion 32 and the plate-like portion 31 may be welding or the like.

  The width (length in the eave direction) of the connecting member 4 is not particularly limited, but it is preferably considered that it is substantially equal to the width (length in the eave direction) of the notch 34. By arranging the connecting member 4 having such a width so as to span the notch 34 of the rising piece 33, the connecting member 4 is sandwiched between the rising pieces 33 provided on the left and right of the notch 34. Will be. Therefore, even if a load due to snow is applied to the face door 3, deformation such as bending and twisting of the connecting member 4 can be suppressed, and deformation of the face door 3 can also be suppressed.

  The roof structure of this embodiment can be constructed, for example, by the following procedure. First, the face door 3 on which the connecting member 4 is arranged so as to bridge between the closed portion 32 and the cutout portion 34 of the rising piece portion 33 is fixed on the field plate 11 using the fixture 9.

In this case, after fixing the face door 3 on the base plate 11, the connecting member 4 is arranged so as to be bridged over the notch 34 of the rising piece 33, and one of the connecting members 4 is used by using the fixture 9. The end portion is fixed to the ridge side surface 32 a of the closing portion 32, and the other end portion is fixed to the plate-like portion 31.

  Next, the concavo-convex roof material 2 is lowered in the direction of arrow A in FIG. 1 so as to abut the face door 3 so that the convex portion 22 is located on the ridge side of the closing portion 32 of the face door 3. Subsequently, the rising piece 33 of the face door 3 corresponding to the inside of each convex portion 22 of the uneven roof material 2 is fitted, and both of the convex portions 33 corresponding to both sides of each rising piece portion 33 are inserted into the uneven roof material 2. It slides and moves in the eaves side direction of the arrow B along the field board 11 while keeping the standing surface part 221 along. As a result, as shown in FIG. 4, the ridge side surface 32 a of the corresponding closing portion 32 abuts against the eaves side end portion of each convex portion 22 of the uneven roof material 2, and the pressing of the corresponding face door 3. Each convex portion 22 is inserted below the portion 321. Further, the rising piece portion 33 is fitted inside each convex portion 22 of the uneven roof material 2.

  Here, the position of the closing portion 32 inserted into each convex portion 22 of the uneven roof material 2 is determined by the positional relationship between the arrangement position of the rising piece portion 33 and the closing portion 32.

Next, the uneven roofing material 2 is fixed to the field board 11 in this state. Thereby, the state in which the eaves side edge part of the convex part 22 of the uneven roof material 2 is inserted under the pressing part 321 of the corresponding face door 3, and
In the state where the rising piece 33 is fitted inside the convex portion 22 of the uneven roof material 2, the field board 11, the face door 3, and the uneven roof material 2 are fixed integrally.

  As described above, according to the roof structure of this embodiment, the connecting member 4 that connects the center portion 32a of the ridge side of the closing portion 32 of the face door 3 and the flat plate portion 31 is provided to reinforce the closing portion 32. can do. Thereby, the deformation | transformation of the face door 3 by the load of the snow accumulated on the uneven roof material 2 or the solar panel P can be suppressed. And the connection state of the uneven roof material 2 and the face door 3 is maintained stably. Moreover, since the convex part 22 of the uneven roof material 2 is fixed so as to be pressed from above by the pressing part 321 of the face door 3, for example, damage or lifting of the uneven roof material 2 due to strong winds can be suppressed.

  Further, since the uneven roof material 2 can be easily positioned by the rising piece portion 33, the opening portion 22 a at the eaves side end portion of the convex portion 22 can be reliably closed by the closing portion 32. For this reason, rainwater, a small bird, an insect, etc. can make it difficult to enter the uneven roof material 2 inside.

  As mentioned above, although the roof structure of this invention was demonstrated based on embodiment, this invention is not limited to said embodiment at all, In the range which does not deviate from the summary, various changes are possible.

  For example, in the above embodiment, the functional panel is the solar power generation panel P, but it may be configured by a panel having other functions. The function panel can be omitted. Furthermore, the present invention is applicable not only to a single-flow roof but also to roofs of other shapes such as a gable roof.
