DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof structure and a construction method using a solar cell panel as a roof member and having excellent rain performance and economy.

[0002]

2. Description of the Related Art When a solar cell panel is mounted on a roof, a mounting frame is generally provided on a roof member having a waterproof function, and the solar cell panel is mounted on the mounting frame. However, there are complaints that the cost is high. On the other hand, there is a roof structure proposed in Japanese Utility Model Publication No. 63-21629, in which a solar cell panel is used as a roof member. Japanese Unexamined Patent Application Publication No. 7-122770 discloses that the problem of the rain between the solar cell module and the frame in the case where the above-described solar cell panel is used as a roof member is solved by providing a “gutter” to form dew condensation water on the back surface of the module. A configuration that discharges intrusion water has been proposed, but has the following problems. After the rainwater that has entered the gutter grooves of the upper frame and the lower frame flows down to the gutter grooves of the side frames, and further flows down to the gutter grooves of the support beams, the rainwater flows into the upper frame, the lower frame, the side frames, and the support beams. There is a problem of water leakage due to flowing down the gutter grooves of three different members, and the cost increases because the gutter members are excessively configured. In addition, in order to maintain the drainage relationship of the multiple members, the side frame 2 of the solar cell panel unit must be fixed to the support bar 7 with a fixing tool 29 such as a screw, and the work is troublesome. There is also a problem of water leakage.

[0003]

The problem to be solved is that when a solar cell is used as a roof member, a roof structure using a solar cell panel which suppresses a rise in cost, is easy to construct, and is excellent in rain-closing. And a construction method.

A. Effects of the Invention According to claim 1, the rainwater that has entered from the holding portion of the underwater frame portion of the support frame holding the solar cell module receives the second water receiver on the waterside extending downward from the holding portion of the overwater frame portion. After flowing down into the groove, the rainwater flows down from the left and right ends of the groove into the gutter of the support member immediately below and is discharged, and the rainwater that has entered from the holding portion of the floating frame portion of the support frame extends downward from the holding portion. The water flows down into the first water receiving groove, which flows out, and flows down from the left and right ends of the groove to the gutter part of the support member immediately below, so that rainwater that has entered between the solar cell module and the support frame can be drained by the gutter of the support member. It is a roof structure that can be drained directly and reliably to the part and has a roof surface that is a solar cell panel and is excellent in rain. And since it is constituted by the minimum number of gutters, it is advantageous in terms of cost and excellent in economic efficiency. Since the solar cell panel is locked and attached to the support member, the roof structure is easy to construct. The mounting of the solar cell panel to the support member can be performed in any of the mounting directions from the underwater side to the upstream side, from the upstream side to the downstream side, and can be performed from any position. Lift the water side of the solar panel
The panel can be mounted and removed with the panel tilted forward.
Can be removed for maintenance such as panel replacement.
Easy to do. B. According to the second aspect, since the water-stopping material that is in contact with the back surface of the solar cell module is formed at the lower edge of the lower part of the first water receiving groove, rainwater flowing along the back surface of the module can be reliably discharged from the first water.

Can be removed. D. According to the fourth aspect, since the locked portion is provided in advance on the support member, no special processing or the like is required at the construction site, so that the construction can be performed efficiently. E. FIG. According to the fifth aspect, the cover member for preventing rainwater from entering between the left and right solar cell panels can be firmly attached. F. According to claim 6, the solar cell panel is held under the water.
By successively attaching the supporting member from the water side to the water side in a state of being raised and tilted forward, the rainwater that has penetrated from the holding part of the water frame part of the supporting frame holding the solar cell module, After flowing down from the holding portion of the floating frame portion to the second water receiving groove portion on the water side extending downward, the water flows down from the left and right ends of the groove portion to the gutter portion of the support member immediately below, and is discharged. Rainwater that has entered from the holding portion of the floating frame portion flows down from the holding portion to the first water receiving groove extending downward, and flows down from the left and right ends of the groove to the gutter portion of the support member immediately below the groove. It is possible to construct a roof structure that excels in the rain that is performed. Then, the solar cell panels can be sequentially mounted from the water upper side to the water lower side, so that an operator does not step on the upper solar cell panel, and damage to the solar cell panel can be prevented.
