That is, the horizontal part 62a of the water guiding part 62 has a funnel-like shape with the upper part spreading.

  The corner drainer 6 described above can be formed by bending a steel plate. Moreover, it can also be set as the corner drainer 6 by shape | molding and combining in some parts. In this case, a caulking material is applied to the seam to increase the water stoppage.

  As shown in FIGS. 2 and 4, the upper surface of the base plate 32 on which the corner drainers 6 and 6 are installed at the corners on both sides is covered with a waterproof sheet 32a such as polyethylene roofing. The waterproof sheet 32a is laid to a position on the inner surface of the roof frame 2, and the entire surface of the field board 32 is covered with the waterproof sheet 32a.

  And the roofing material 4 is installed from the top of this waterproof sheet 32a. The roofing material 4 is formed of, for example, a hot-dip aluminized steel sheet having excellent waterproof performance and corrosion resistance.

  The roofing material 4 includes a rectangular flat plate portion 40 that is stacked on the base plate 32, standing wall portions 41 and 41 that rise substantially vertically from both side edges of the flat plate portion 40, and upper ends of the standing wall portions 41 and 41.

As shown in FIGS. 2 and 5, receiving metal fittings 11 </ b> A and 11 </ b> B for fixing to the roof frames 2 and 2 are attached to both side edges of the solar cell module 1.

  The brackets 11 </ b> A and 11 </ b> B have different lengths (heights) when the solar cell module 1 is tilted and attached to the roof frame 2. Here, the bracket 11A is shortened and the bracket 11B is lengthened. In addition, when attaching the solar cell module 1 in parallel with respect to the upper surface of the roof frame 2, the length (height) of the receiving metal fittings 11A and 11B is made the same.

  As shown in FIG. 5, the solar cell module 1 is fixed by screwing a drill screw 13 passed through the metal fittings 11 </ b> A and 11 </ b> B into the upper flange 23 of the roof frame 2.

  The lower surface of the solar cell module 1 attached in this way is separated from the upper surface of the roofing material 4. That is, there is a gap between the upper surface of the roofing material 4 and the lower surface of the solar cell module 1 that allows rainwater or the like to flow down.

  The roof panel 10 manufactured in a factory or the like as described above is transported to the construction site, lifted by a crane, and placed side by side on the building units H1,.

  Then, the roof structure of the unit building H constructed by arranging a plurality of roof panels 10,. First, as shown in FIG. 6, the roof panels 10 are arranged one by one on the building units H1,.

  The roof panel 10 is installed across a plurality of building units H1,. The relationship between the length of the roof panel 10 and the number of building units H1,.

  In the present embodiment, as shown in FIG. 7, a single roof panel 10 is spanned in the direction of the wife of the three building units H1, H1, and H1, and the eaves end is projected in a bowl shape.

  As shown in FIG. 6, a bolt 21b is passed through a connecting hole (not shown) in the lower flange 21 of the roof frame 2, and is passed through a hole H121 provided in the girder roof beam H12 and fastened by a nut 21c.

  The appearance of the unit building H in which the entire surface of the flat roof is covered with the roof panels 10,... By installing the plurality of roof panels 10,. .

  Next, the operation of the roof structure of the unit building H constructed by installing the corner drainer 6 of the present embodiment, the roof panel 10 to which the corner drainer 6 is attached, and the roof panel 10 will be described.

  The corner drainer 6 of the present embodiment configured as described above is disposed at the corner portion between the end portion of the field plate 32 and the web 22 of the roof frame 2 intersecting the field plate 32. And the installation piece part 61 superimposed on the field board 32 and the water guide part 62 formed toward the downward direction from the edge part on the water side are provided.

  The corner drainer 6 can be attached simply by placing the installation piece 61 on the base plate 32 and covering the waterproof sheet 32a and the roofing material 4 from above. The work is easier than if it had to be.

  Further, the fixing to the roof frame 2 can be performed using the rivets 67 and 67 while adjusting the positions of the long holes 66 and 66 of the side piece 63, so that it can be performed in a short time.

  Furthermore, since the water side of the side piece part 63 will be covered in the state inserted in the inside of the standing wall part 41 of the roofing material 4, between the side piece part 63 and the standing wall part 41 separately, There is no need to perform water-stop treatment with water-stop tape.

  Even if rainwater or the like flowing down the flow surface of the roofing material 4 of the roof panel 10 forming a roof having a gentle or nearly horizontal slope such as a flat roof gathers in the corner portion, the corner drainer 6 promptly Can flow down.

  That is, as shown by the arrows in FIG. 1, most of the rainwater flowing on the roof surface (flow surface) which is the upper surface of the flat plate portion 40 of the roofing material 4 passes through the draining edge 43 and remains as it is. It is drained towards.

  On the other hand, the water that has flowed into the corner part falls to the floor surface part 623 of the horizontal part 62a of the water guide part 62, and then quickly flows out to the eaves surface 5 through the vertical part 62b. For this reason, even if the eaves surface 5 is not formed up to the end reaching the roof frame 2, a roof structure with a drainage structure having a sufficient drainage function that can guide the water collected at the corner to the eaves surface 5. Can do.

  Moreover, the water conveyance part 62 is made into the structure which has the floor part 623 used as a flow surface, and the 1st side part 621 and the 2nd side part 622 which are provided in the both sides, and it is surely an eaves surface without making it leak in the middle 5 can be led to water.

  Furthermore, by providing the side piece 63 that extends upward from the end of the installation piece 61 to the base plate 32 along the web 22, it is allowed to overflow even if the amount of water flowing down the roof surface increases. It will be possible to drain well.

  Further, by covering the inner surface side of the web 22 with the side piece 63, it is possible to prevent water from flowing around the roof frame 2 side. Moreover, such a water stop structure can be constructed without performing a water stop treatment with a waterproof tape or a caulking material.

  And if the corner | angular part 64 is formed by the side piece part 63 and the 2nd side part 622, the water guide part 62 will smoothly flow without letting the water discharged | emitted from the draining edge 43 leak underwater. Can lead to.

  Moreover, the solar cell module 1 is arrange | positioned with the roof panel 10 with respect to the roofing material 4 which has waterproof performance. Furthermore, a gradient is formed in the flat plate portion 40 that is the upper surface of the roofing material 4 in the longitudinal direction of the roof frame 2.

  For this reason, even if the roof is flat like a flat roof, a roof structure having high waterproof performance and drainage performance can be easily constructed only by arranging and fixing the roof panels 10,.

  That is, since the lower part of the roof panel 10 is covered with the roofing material 4, high waterproof performance can be ensured. In addition, since a slope is formed on the upper surface of the roofing material 4, rainwater can flow down by the slope formed on the flat plate portion 40 even if the roof panel 10 itself is installed horizontally. Furthermore, the water that has gathered at the corner portion can be quickly caused to flow toward the eaves surface 5 by the corner drainer 6.

  Moreover, since the upper surface of the roofing material 4 and the lower surface of the solar cell module 1 are separated from each other, it is possible to prevent the solar cell module 1 from being prevented from flowing down and stagnation of drainage. Furthermore, since water does not collect around the solar cell module 1, it is possible to prevent the occurrence of breakdown or electric leakage.

  And the guide part 3 matched with the desired inclination is provided in the inner surface side of the web 22 of the roof frame 2, and the upper surface of the roofing material 4 mounted on it is easily formed in the desired inclination. Can do.

  Furthermore, if the guide part 3 is constructed by the support members 31 and 31 fixed to the roof frames 2 and 2, respectively, and the base plate 32 that supports both side edges of the support members 31 and 31, a base surface is formed. Will be. If there is a base surface to be a support, for example, a roofing material 4 having a thin plate thickness (low rigidity) can be used for stable support. Further, even if the roofing material is not formed of a single plate, it is only necessary to connect the roofing materials on the field board 32, so that any form of roofing material can be used.

  Further, the upper edge portion 42 that is continuous in a planar shape is stacked on the upper flange 23 that is the upper surface of the roof frame 2, so that the roof between the pair of roof frames 2 and 2 has no gap. It will be covered with the wiping material 4, and waterproof performance can be improved.

  And the land roof excellent in waterproof performance and drainage performance can be constructed | assembled only by installing the above roof panels 10 on the roof beam (H12, H13) extended in a horizontal direction.

  Moreover, the roof panel 10 can be reliably fixed by joining the lower part of the roof frame 2 with the volt | bolt 21b etc. to the upper surface of a roof beam (H12, H13).

  Hereinafter, a roof structure of a building according to an embodiment different from the above-described embodiment will be described with reference to FIG. The description of the same or equivalent parts as the contents described in the above embodiment will be described with the same terms or the same reference numerals.

  In this embodiment, the roof structure on the eaves end side that is the opposite side of the roof panel 10 with the eaves ridge surface 5 interposed therebetween will be mainly described. The eaves end is projected from the outer wall 83 to form a flange 80, and the end surface is covered with the parapet 7.

  Then, the lower surface of the flange 80 is blocked by the eaves ceiling 8. The eaves ceiling 8 extends along the outer wall 83 in a direction orthogonal to the paper surface of FIG. Also, an eaves wall 50 is laid on the upper surface of the eaves ceiling 8. Since the eaves bowl 50 is provided with a drainage gradient with respect to the direction orthogonal to the paper surface of FIG. 8, the eaves bowl 50 floats away from the eaves ceiling 8 depending on the position.

  The eaves wall 50 is connected to the wall 82 at the most downstream point. A water collector 81 is interposed between the eaves 82 and the eaves eaves 50. That is, a drainage port is perforated at the bottom surface of the eaves rod 50 at the most downstream point, and the water that has flowed down from the drainage port flows into the rod 82 through the water collector 81.

  Here, the corner drainer 6A described in the examples is substantially the same as the configuration of the corner drainer 6 described in the above embodiment, but only the configuration of the tapered portion 65A is slightly different. Since other configurations are the same, description thereof is omitted.

  The tapered portion 65A has a shape in which an upper wall portion 651 extending in the vertical direction is added to the upper end edge of the inclined surface similar to the tapered portion 65 described in the above embodiment. By providing the upper wall portion 651 in this manner, water leakage can be prevented while suppressing the funnel-shaped spread.

  And the upper cover 71 which protrudes on the roof panel 10 side is attached to the upper surface of the parapet 7. The upper cover 71 has a downward slope toward the corner drainer 6A, and the tip 71a is accommodated in the corner drainer 6A. A draining edge 43 of the roofing material 4 is disposed below the tip 71a.

  In the roof structure of the embodiment configured as described above, rainwater that has fallen on the roof panel 10 flows on the surface of the roofing material 4 and flows into the eaves wall 50 through the draining edge 43 or the corner draining material 6A.

  Moreover, the rain water which fell to the parapet 7 side flows on the surface of the upper cover 71, and flows into the eaves 50 through the corner drainer 6A or directly. For this reason, all the rainwater that has fallen on the roof structure can be quickly collected in the eaves 50 and drained from the eaves 82.

  In this embodiment, the case where the corner draining material 6A is arranged has been described. However, the present invention is not limited to this, and the corner draining material 6 described in the above embodiment can naturally be arranged. Other configurations and functions and effects are substantially the same as those in the above-described embodiment, and a description thereof will be omitted.

It is also possible to configure the length of one side of the building by connecting a plurality of roof panels in the longitudinal direction. For example, two roof panels can be connected in the longitudinal direction to have the same length as the roof panel 10 shown in FIG.

  Furthermore, in the said embodiment, although the case where the guide part 3 comprised by the supporting materials 31 and 31 and the field board 32 was provided was demonstrated, it is not limited to this, Both the side edges of the field board 32 are directly covered. The roof frames 2 and 2 may be joined. Furthermore, it is not limited to the field board 32 to directly place the installation piece 61 of the corner drainer 6 but may be configured to be placed on the waterproof sheet 32a. Further, the base plate is not limited to the field plate 32.

  And although the said embodiment demonstrated using the solar cell module 1 as a shielding plate-shaped member, it is not limited to this. For example, in an area where there is a lot of snow, a shielding plate for snow can be used as the shielding plate member. By incorporating this shielding plate on the top surface of the roof panel, it is possible to reduce the snow load that acts on the field plate 32 attached to the roof frame 2.

  Moreover, the shielding board as a shielding board-like member can be integrated in the location where rain water blows up easily such as the eaves. That is, if the upper part of the roofing material 4 is covered with the shielding plate, it is possible to prevent the rainwater on the roofing material 4 from blowing up and leaking from the gap between the adjacent roof frames 2 and 2. Therefore, the waterproof performance of the entire roof is enhanced.
