However, the former has a structure in which a solar cell is separately provided on the existing roof, so there is a roof below the solar cell, and there is no major problem with rain.However, there is a problem that the design of the building itself is impaired. there were. On the other hand, in the latter, by unitizing the solar cell, the solar cell can be constructed as a roof panel, and the problem of impairing the design of a building has been solved. However, the latter is different from the former, which has a roof under the battery, in terms of the rain action against rainwater, etc., and the issue is how to perform the rain action at the joint part of the solar panel. Has become. For example, in the above prior art, a solar cell is installed on a roof base made of a haze material, a base material laid on the haze, and the like. Although it has a structure to form a plurality of gutters on the frame material etc. so as to prevent rainwater intrusion using multiple members, and to be able to drain invaded rainwater without flooding indoors As a result, the frame material and the like constituting the solar cell unit are complicated, and the number of members at the joint portion is increased, resulting in a problem of a rise in cost.

[0003]

The first object of the present invention is to provide an exterior structure using a low-cost solar cell panel without deteriorating the design and rainfall of the building itself. 2, an exterior structure using a solar cell panel which has high rainfall performance without rain water flowing between the solar cell panel surfaces and between the adjacent solar cell panels to the back side of the panel, and Further, an exterior structure using a solar cell panel having high rain performance without rainwater flowing from each solar cell panel surface to a rear surface side of the rainwater flowing between vertically adjacent solar cell panels, and fourthly, Furthermore, an exterior structure using a solar cell panel having high rain performance without rain water flowing between the vertically adjacent solar cell panels and between the left and right solar cell panels to the back side of the joint member. Sa To, to provide a smooth treated exterior structure weathering properties with high solar panel flooding from anchoring portion of the solar cell panel.

[0004]

According to the present invention, there is provided an exterior structure in which a solar cell panel is laid on a skeleton such as a steel frame. A skeleton is constructed by arranging and fixing drainage structural materials having a drainage vertical space that is continuous in the direction and has an open upper surface, and the side surface, water lower surface, and water upper surface are located between the left and right adjacent drainage structural materials. A solar cell panel composed of a frame member is arranged such that the side frame material end of the panel faces the drainage space of the drainage structural material, and the side frame material is used for drainage directly or indirectly via a mounting member. Along with fixing to the structural material, on the back side in the flow direction end of the solar cell panel, there is a drainage horizontal space that is open at the top,
The drain horizontal space has an end provided with a joint member facing the vertical drainage space of the drainage structural material. Further, in the present invention, the side frame member has a hanging piece formed at an end thereof, and the hanging piece faces the drainage vertical space of the drainage structural material. Also, in the present invention, the underwater / overwater frame material has a hanging piece at an end thereof,
The hanging piece faces the drainage horizontal space of the joint member. Further, in the present invention, the joint member has a hanging portion formed at an end portion, and the hanging portion faces the drainage vertical space of the drainage structural material. Further, in the present invention, the drainage structural material is characterized in that a fixing portion to which the side frame of the solar cell panel is fixed is formed on the drainage vertical space.

[0005] The skeleton in the present invention is a purlin or beam made of H-section steel, C-section steel or the like and arranged in the lateral direction (girder direction). Structural material for drainage has a shape with flanges extending outward or inward, such as C-shaped or inverted hat type, a shape with flanges extending outward and inward, and a flange having a substantially U-shape. It may have any shape that does not have it, a shape similar to these, and the like. The structural material for drainage is formed by connecting a threading material or a fixed-length material, and when the length of the roof (frame) in the flow direction is short, the structural material may be used as a threading material and also serve as a flowing water member. When the length in the flow direction is long (when it is necessary to join a structural material), it is only necessary to connect and provide a waterproofing means to the connecting portion. The drainage structural material is welded to the frame (may be directly welded or may be welded through an L-shaped angle or the like), and is fastened with a fixture such as a screw or a bolt (for fixing to the bottom of the structural material) Any suitable means can be used as long as it is fixed by a known fixing means for constructing a steel frame such as a form in which a convex portion is formed or a fixing flange is formed outside the structural material. The side frame fixes the fixing portion extending outward from the hanging piece directly or indirectly through a mounting member to the drainage structural material. , Bolts or the like are preferably used. In the solar cell panels adjacent to each other in the left-right direction and the flow direction, adjacent side edges may be arranged in abutting (adjacent) state, or may be arranged in an opening shape with an interval. Further, a joint material such as a cover may be provided between the side edges. The joint member has a length relationship capable of guiding inflow water from the end to the drainage vertical space, that is, longer than the interval between the structural material side walls between the drainage structural materials, and the width of the solar cell panel (underwater / overwater frame). Length). The joint member may be in a form separate from the underwater / overwater frame, or may be formed integrally. Further, in the case of being integrated, it may be formed integrally in advance, or a separate body may be welded,
It may be integrated by known means such as adhesion, engagement, and screwing. In addition, the joint member is provided with a rubber sheet or the like adhered to the bottom surface or the surface of the hanging portion, and is brought into close contact with the lower end of the underwater / above-water frame, thereby improving the water stopping performance. This rubber sheet may be attached to at least the bottom surface. The drooping piece of the side frame may have a form in which the lowermost end faces the vertical drainage space, and the infiltration water flowing down the side frame may drop down to the drainage structural material along the drooping piece. In this regard, the same applies to the hanging pieces of the underwater / overwater frame that guide the intruded water to flow down into the horizontal drainage space. The drooping portion of the joint member may be configured so that the rainwater flowing down the drainage horizontal space flows down the drooping portion without falling to the back surface and smoothly flows down (falls) into the drainage structural material, as in the illustrated embodiment. However, it is not always necessary to provide it on the entire side wall and bottom surface. The hanging portion may be formed integrally or may be in a mode of attaching a separate body. The fixing portion of the drainage structural material preferably has a form in which a flowing water space is formed below the fixing portion, and is effective in smoothly treating inundation from a fixing portion such as a screw. This fixing portion may be formed on a flange portion extending inward from the side wall of the structural material, or may be provided integrally or separately in the drainage space.
