Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof panel constituting a roof of a building.

[0002]

2. Description of the Related Art Recently, a unit type roof panel that constitutes a roof of a building is known. These roof panels are
Usually, a waterproof layer is provided on the top plate of the roof panel main body, and a plurality of rows of roofing materials are provided on the waterproof layer.

[0003]

However, when a plurality of rows of roofing materials are provided on the waterproof layer as described above, when rainwater or the like penetrates into the waterproofing layer through the gaps between the roofing materials, the rainwater, etc. However, there is a problem that nails and the like that are fixed on the roof material and the like are likely to corrode by accumulating on the waterproof tank. The present invention has been made to solve the above problems, and when a rainwater or the like permeates on the waterproof layer through the gap between the roofing materials, the roof panel is configured to be able to quickly drain the rainwater to the eaves side. The purpose is to provide.

[0004]

In order to solve the above-mentioned problems, a roof panel according to the present invention is provided with a waterproof layer on a top plate of a roof panel body, and a plurality of rows of roofing material are arranged vertically and horizontally on the waterproof layer. A vertically long draining sheet was laid under the joint between the roofing materials arranged side by side, and the ridge-side end of the draining sheet was folded back so as to overlap with the draining sheet.

[0005]

[Operation] Rainwater that has permeated from the joints between the roofing materials arranged side by side is guided to the draining sheet laid below and is quickly drained to the eaves. In addition, the rainwater that has penetrated into the ridge side of the draining sheet is prevented from leaking into the room from the ridge portion because the folded-back portion of the draining sheet prevents backflow to the ridge side.

It is a partial perspective view of the roof panel which shows a state.

In this roof panel 100, a waterproof layer 130 formed by roofing or the like is provided on a top plate 111 of a roof panel body 110, and a vertically long draining sheet 150 is provided on the waterproof layer 130. A plurality of vertically long spacers 160 having substantially the same height as the draining sheet 150 are arranged. A plurality of roofing materials 170 are vertically and horizontally arranged on the spacers 160, and a joint portion between the roofing materials 170 arranged side by side is positioned on the vertically long draining sheet 150.

The structure of the roof panel 100 will be described according to the order of its production. Roof panel body 100
As shown in FIG. 1, the roof frame 114 is formed by arranging a plurality of vertical core members 112 and horizontal core members 113 in parallel.
The top plate 111 is mounted on the top, and the purlin 115 is mounted on the outer side of the lateral core material 113 at the ridge side end.

At the eaves side end of the roof panel body 110 on the top plate 111, as shown in FIG.
The 0 is attached to the eaves by nails 121 or the like. As shown in FIG. 3, the waterproof layer 130 is provided on the top plate 111 of the roof panel main body 110 to which the eaves drainer 120 is attached, for example, by roofing.

As shown in FIGS. 4 and 5, a waterproof sheet 140 is attached to the roof side of the roof panel main body 100 provided with the waterproof layer 130 so as to project toward the ridge. For example, staple 141 is attached.
Etc. As shown in FIG. 6, lines 136 and 137 at the roof material installation position are drawn vertically and horizontally on the upper surface of the roof panel body 100 to which the waterproof sheet 140 is attached.

Next, as shown in FIG. 7, the line 136,
Vertically long draining sheets 150 are disposed by staple 151 or the like at the center and the left end of the upper surface portion of the roof panel body 110 that has been pulled. The draining sheet 150 is provided with a plurality of vertically elongated draining grooves, for example. In the case of this embodiment, the draining sheet 15 at the left end thereof
The left half of 0 is in a state of protruding to the left side of the roof panel body 110. Then, as shown in FIGS. 8 and 9, the draining sheet 1 is placed on the waterproof layer 130 of the roof panel body 110 to which the draining sheet 150 is attached.
A plurality of spacers 160 having substantially the same height as 50 are arranged in parallel by nailing or the like.

Then, after that, on the roof panel main body 110 to which the spacer 160 is attached,
As shown in FIG. 10, a plurality of roofing materials 170 are vertically and horizontally arranged along the lines 36 and 137. In the case of this embodiment, the joints between the roofing materials 170 arranged in two rows vertically are located on the central portion of the central draining sheet 150, and the left end of the left roofing material 170 is the left draining sheet. It is located on the center of 150. Then, roofing material 170
The ridge-side end of the draining sheet 150 protruding from the lower side to the ridge side is folded back so as to overlap with the upper side of the draining sheet 150 as shown in FIG. 11. Then, in the folded state, the roof panel body 11 is driven by nailing 151 or the like.
It is fixed at 0. By being folded in this way,
The rainwater that has permeated the ridge side of the draining sheet 150 is blocked by the folded portion of the draining sheet 150, and does not leak into the room from the ridge portion.

After that, the ridge-side end of the waterproof sheet 140 projecting from the lower side of the roof material 170 to the ridge side is further shown in FIG.
As shown in FIG. 2, the water resistant sheet 140 is folded back so as to overlap with the upper side, and the tip of the folded side is inserted into the lower side of the draining sheet 150. By being folded back in this way, the waterproof sheet 140
The tip of the is not an obstacle during the transportation of the roof panel 100 and the assembly work on the building. Then, after the assembly, the ridge-side end of the water resistant sheet 140 may be extended as it is.

Since the roof panel 100 according to this embodiment is constructed as described above, the roofing materials 17 arranged side by side are provided.
Rainwater that has penetrated into the interior through the gap between the 0 joints is drained through the draining sheet 150, and rainwater that has penetrated into the interior from other locations between the roof 160 formed by the spacer 160 and the waterproof sheet 130. It will be promptly discharged through the space between them.

In the above-mentioned embodiment, an example of roofing is used as the waterproof layer on the top plate 111, but any waterproof layer such as a waterproof sheet or a waterproof coating may be used. Good. Also, the draining sheet 15
As for 0, any structure may be used as long as the rainwater reaching the draining sheet 150 can flow down in the eaves side direction.

Further, the height, width, length, number, installation position, etc. of the spacers 160 may be freely designed and modified within a range not impairing their functions. Further, the folding back of the ridge-side end of the draining sheet 150 is not limited to the above folding back, and rainwater that has penetrated into the ridge side of the draining sheet 150 prevents backflow to the ridge side by the folding portion of the draining sheet 150. If necessary, the ridge side end of the draining sheet 150 may be folded back so as to be overlapped with the lower side of the draining sheet 150.

[0017]

EFFECTS OF THE INVENTION Rainwater that has permeated from the joints between roofing materials arranged side by side is quickly guided to the eaves side by being guided by the draining sheet laid below it. In addition, the rainwater that has penetrated into the ridge side of the draining sheet is prevented from leaking into the room from the ridge portion because the folded-back portion of the draining sheet prevents backflow to the ridge side.
