an upper inner rising portion 3 having an inverted U-shaped cross section rising from one edge in the width direction; a flat portion 4 extending along the main body portion 2 from an edge of the upper inner rising portion 3; 4 and a seal attachment portion 5 rising from the edge of the body portion 2.
an inclined part 6 extending downward from the other end in the width direction; a hanging part 7 hanging down from the edge of the inclined part 6; and a hanging part 7 extending inward from the lower edge of the hanging part 7. A plurality of roof panels 1 having stepped engagement portions 8 are arranged in parallel in the width direction, and each roof panel 1
One end of the base material 1 in the width direction is attached to the base material 1 through a hanger 9 that is fitted into the upper inner rising portion 3 from above.
0, and the engaging part 8 of one roof board 1 adjacent in the width direction is connected to the engaging part 8 surrounded by the main body part 2, the upper inner rising part 3, and the flat part 4 of the other roof board 1. The engaging portion 8 is inserted into the mating recess 11 and
By the plunge engagement into the engagement recess 11, the two adjacent roof panels 1, 1 are connected in the longitudinal direction thereof, and the seal attachment portion 5 of the other roof panel 1 is connected.
The sealing member 12 attached to the one roof plate 1
The connecting portion of both roof panels 1, 1 is sealed in the longitudinal direction by being brought into pressure contact with the inclined portion 6 of the roof panels 1, 1. Further, a sheet-like heat insulating material 13 is adhered to the back surface, that is, the lower surface, of the main body portion 2 of each roof panel 1 to prevent dew condensation.

部分にガタツキを生じる虞れがある。(Problem to be solved by the invention) However, in such a conventional horizontal roof, the connection between the adjacent roof panels 1, 1 causes the engaging portion 8 to move in the parallel direction of the roof panels 1... This is done by inserting the engagement part 8 into the engagement recess 11 along the longitudinal direction, and in this engagement connection part, the engagement part 8 is pulled out from the engagement recess 11 along the parallel direction of the roof panels 1. There is no means provided to prevent this from happening, and the function of preventing it from coming off is only achieved by fixing the hanger 9 to the base material 10, so it is inevitable that it will be affected by wind, etc. There is a possibility that the engagement and connection portion of the roof panels 1, 1 may become loose.

めて面倒である。 Furthermore, since the degree to which the engaging portion 8 enters the engaging recess 11 cannot be visually recognized from the outside and cannot be confirmed from the external appearance of the connecting portion of the roof panels 1, 1, the engaging recess of the engaging portion 8 cannot be confirmed from the outside. Coupled with the fact that the engagement with No. 11 is carried out over a long range along the longitudinal direction of the elongated roof board, there is a possibility that such engagement will not be carried out sufficiently and reliably over the entire length in the longitudinal direction. . As described above, if there is a portion where the engagement part 8 is not fully engaged in the engagement recess 11, the engagement part 8 may come off the engagement recess 11 due to the influence of the wind or the like. The rattling will become more noticeable, and
Depending on the poor engagement of the engaging portion 8, the parallelism of the roof panels 1 may not be ensured, which may result in poor external appearance. Even if the parallelism of a pair of roof panels 1, 1 becomes defective, the degree of defect is so slight that the worker will not notice it, but the roof panels 1, 1 that were subsequently installed... In view of the relationship, the degree of parallelism failure becomes so large that it can be clearly recognized visually. When the degree of failure becomes visible, the operator naturally notices that there is a failure in the engagement of the engaging part 8, but in this case, if he tries to correct the parallelism, he will have to do roofing work. You have to start over from the beginning, which is extremely tedious.

There is a risk that rainwater may enter.

い場合よりも良好に行われることになる。 Therefore, in a horizontal roof with such a configuration, the ridge side part of the eave side roof board 21 (the one on the left in FIG. 3) is
It is fixed to the rafters 30 through the hangers 29 that are fitted into the upper inward rising portion 23 and the inner fitting recessed portion 24 from above, and the roof on the ridge side is attached to the inner fitting recessed portion 24. Fit the outer fitting concave portion 25 of the eave side portion of the plate 21 (the one on the right side in the figure) from the lower side,
Further, the ridge-side flat plate portion 22a of the main body portion 22, which is the ridge-side portion of the ridge-side roof plate 21, and the upper inward rising portion 2
3 and the inner fitting concave portion 24 are fixed to the rafters 30 through the hangers 29, and the roofing work is repeated from the eaves side to the ridge side. By the way, the fitting of the outer fitting recessed part 25 into the inner fitting recessed part 24 is performed by the roof plate 21 on the ridge side.
While tilting with respect to the roof board 21 on the eave side, pull it towards the ridge side, and first, guide the inner fitting recessed part 24 relatively between the eave side flat support plate part 22b of the main body part 22 and the draining part 26. (FIG. 3A), while further guiding the inner fitting recessed part 24 by the draining part 26, the lower end part thereof is placed in the outer fitting recessed part 25, that is, between the hanging plate part 25a and the rising plate part 25c. (Fig. 3B), the ridge side flat part 22 of the ridge side roof board 21
a and the eave side flat plate part 22b are respectively received by the rafters 30... and the ridge side flat plate part 22a of the eave side roof board 21 (and the hanger 29... which holds it). This can be done easily and reliably by rotating the roof plate 21 on the ridge side downward (FIG. 3C). In this case, as long as the lower end portion of the inner fitting recess 24 protrudes even slightly into the outer fitting recess 25, the outer fitting recess 25 will then move into the inner fitting recess as the roof plate 21 rotates. 24 over its entire length in the longitudinal direction, and there is no possibility of incomplete fitting of the outer fitting recess 25 to the inner fitting recess 24 in the longitudinal direction. Further, due to the presence of the draining portion 26, it performs a guiding action during fitting, and the insertion of the inner fitting recessed portion 24 into the outer fitting recessed portion 25 is performed better than in the case where the draining portion 26 is not provided. You will be killed.

る。 Note that the configuration of the horizontal roof is not limited to the above embodiment, and for example, as shown in FIG. The ridge side roof board 21 is changed from the state shown in FIG. 3A to the state shown in FIG. The inner fitting recess 2 of the outer fitting recess 25 is minimized to minimize interference with the eave side roof board 21 when changing the
It is possible to adopt a shape devised so that the fitting operation to 4 can be performed more easily. Furthermore, the cross-sectional shape of the upper inward rising portion 23 is shaped like a step or approximately C-shaped as shown in FIG.
It is also possible to form each in a character shape. Further, the heat insulating material 27 may be attached to the entire back surface of the roof sheet 21 including the draining portion 26, but at least on the eave side portion of the roof sheet 21, it is attached to the hanging plate portion 25a of the external fitting recessed portion 25. It is fine as long as it reaches that point. In short, the inner fitting recess 24 and the outer fitting recess 25 that fit therein are capable of exhibiting a predetermined dew condensation prevention function.
It is only necessary that the adhesive be adhered over a longitudinal range such that it can be pressed against the opposing surface and exert a predetermined sealing function. Further, although it is not necessary to provide the draining plate 26, if it is provided in an inclined shape and long as in the above embodiment, the ridge side flat plate portion 22 of the main body portion 22
Rainwater entering the upper inner rising portion 23 from between the flat plate portion 25b of the outer fitting recess 25 and the hanging plate portion 24a of the inner fitting recess 24 and the outer fitting recess 25 It is possible to effectively prevent intrusion from between the upper inner rising portion 25c and the outer fitting recessed portion 2.
It has the advantage that it also functions as a guide plate that makes fitting into the inner fitting concave portion 24 of No. 5 easier and more reliable.

外観体裁の良い横葺屋根を提供できる。 Furthermore, in connection work between roof panels, as long as the lower end of the inner fitting recess protrudes even slightly into the outer fitting recess, the outer fitting recess can be properly fitted into the inner fitting recess. will be held. If there is a place where such plunge fitting is not performed at all, the appearance of the roof shingles will change markedly in the vertical direction at this place, and such an abnormality in the appearance will be clearly confirmed by the operator. This makes it possible to carry out correction work immediately. Therefore, according to the present invention, even though the roof panels are long, the connection between the roof panels by fitting the outer fitting recess into the inner fitting recess can be achieved by redoing the roofing work. This can be done properly and reliably over all parts in the longitudinal direction without causing such troubles, and it is possible to provide a horizontally-roofed roof with good appearance and good appearance.

ては構造のシンプル化を図りうる。 Moreover, since the outer fitting recess is properly fitted into the inner fitting recess in this way, the sealing effect by the heat insulating material interposed between the opposing surfaces of both parts is uniform throughout the longitudinal direction. This is done well, and as mentioned above does not cause rattling, there is no risk of rainwater entering from the joints between the roof panels. Moreover, since this sealing function is performed by a part of the insulating material for preventing condensation, there is no need to separately provide a special sealing member like in the conventional roof mentioned at the beginning, and the number of parts can be reduced and extended. In this case, the structure can be simplified.
