Japanese Unexamined Patent Publication No. 2013-144917

Generally, when a solar panel is installed as a functional panel on the roof surface of a building, for example, it is desired that the number of solar panels installed on the roof surface is large in order to increase the total power generation amount. Therefore, for example, it is conceivable to spread solar panels on the roof surface without gaps. On the other hand, the solar panels installed on the roof surface and the roof surface require regular maintenance, and if the solar panels are spread without gaps, the workability during maintenance is reduced.

An object of the present invention is to provide a functional panel arrangement structure capable of suitably performing maintenance while installing many functional panels on a roof surface.

Function panel arrangement of the present invention, the panel row formed by concatenation of multiple functions panels, and a generally functional panel arrangement that is more than placed on a flat roof, between the adjacent plurality of panels columns A passage is formed in, and the end panel row, which is at least one of the panel rows arranged at both ends, is arranged along the outer peripheral edge of a substantially flat roof, and the end panel row and the outer peripheral edge arranged along the outer peripheral edge. The width between and is smaller than the width of the passage.

According to such a functional panel arrangement structure, since the end panel rows can be arranged close to the outer peripheral edge, the number of functional panels arranged on the roof surface can be increased. On the other hand, since the panel rows are arranged so as to have a passage, all the panel rows are provided with a passage adjacent to each other. Therefore, the worker can move the roof surface by walking along the passage. Therefore, maintenance can be suitably performed while installing many functional panels on the roof surface. Also, if the functional panel is a functional panel that converts sunlight into electricity or heat, the panel rows are arranged with a passageway, so the shadow of the functional panel in the front row located in the direction of sunlight is adjacent. It is possible to suppress the influence on the function panel in the back row.

Further, the functional panel of the end panel row may be detachably attached to a substantially flat roof via an attachment portion that can be removed from the aisle side. In this case, the functional panel can be attached / detached to / from the end panel row only by the removal operation from the aisle side.

Further, the functional panel may be attached to a substantially flat roof via a gantry. In this case, a plurality of functional panels can be easily arranged side by side in an orderly manner.

Further, the mounting portion includes a fastening portion for fixing the functional panel to the gantry, and the removal operation may be a tightening / loosening operation of the fastening portion. In this case, the functional panel can be fixed to the gantry by a relatively simple structure.

Moreover, the substantially flat roof has a rectangular area, at least three sides of the rectangular region, south, east, and is disposed on the west side, the panel row group consisting panel columns of multiple corresponded to the rectangular region It is rectangular and the edge panel rows are arranged along the southern outer perimeter of the rectangular region, with at least one of the eastern and western flanks of the panel row group and the outer perimeter of the rectangular region. A north-south passage that communicates with the passage and extends in the north-south direction may be formed between them. According to this, even if a plurality of passages are formed, all the passages are connected to the north-south passage. Therefore, by passing through the north-south passage, it is possible to easily move from one passage to another.

Further, the substantially flat roof may be provided with an elevating means leading from the north-south passage to the downstairs and an installable structure for attaching the elevating means. Further, the lower end of the elevating means may be connected to a veranda downstairs or an empty space on the ground. Even when a plurality of passages are formed, all the passages can be easily accessed from the elevating means via the north-south passage.

Further, at least one of the column bases supporting the gantry may be arranged above the roof beam along the outer peripheral edge. By arranging the column base above the roof beam along the outer peripheral edge, the functional panel can be installed up to the outermost peripheral portion of the roof surface as long as the center of gravity does not go out. In addition, the load of the functional panel is transmitted to the column base via the gantry. Since the column base is located above the roof beam, the load received by the column base is transmitted to the roof beam below. This eliminates the need for an auxiliary beam for receiving the column base, which is advantageous for weight reduction.

Further, in the above-mentioned functional panel arrangement structure, the functional panel has a rectangular shape, and the short sides of the plurality of functional panels are connected to each other to form a panel row, or the long sides of the plurality of functional panels are connected to each other to form a panel. Rows may be formed.

According to the functional panel arrangement structure of the present invention, maintenance can be suitably performed while installing many functional panels on the roof surface.

In FIG. 2, the upper side of the paper shows the north side, and the lower side, the right side, and the left side show the south side, the east side, and the west side, respectively. For convenience of explanation, the lower side of the paper may be the front and the upper side of the paper may be the rear. As shown in FIG. 2, a plurality of solar panels 50 are arranged on the flat roof 3 of the building 1. The flat roof 3 of the building 1 has a roof surface which is a rectangular region 3a having a substantially rectangular shape in a plan view. This rectangular region 3a is the inside in a plan view of the parapet 6 formed along the outer peripheral edge 4 of the roof surface of the flat roof 3.

The outer peripheral edge 4 determines the position of the line of intersection between the virtual vertical surface and the roof surface passing through the center of the outer peripheral beam 2a arranged along the outer periphery of the building 1 among the roof beams 2 constituting the frame of the building 1. I'm assuming. Even if the building has an eave, if there is a beam on the outer peripheral part of the eave, the beam on the outer peripheral part of the eave is used as the outer peripheral beam. It consists of a south edge 4S which is an outer edge on the south side, a north edge 4N which is an outer edge on the north side, an east edge 4E which is an outer edge on the east side, and a western edge 4W which is an outer edge on the west side. A plurality of solar panels 50 are connected in the east-west direction to form a panel row R. The connection includes not only the case where the adjacent solar panels 50 that are continuously arranged are in strict contact with each other, but also the case where the solar panels 50 are arranged with a predetermined gap. For example, even if adjacent solar panels are connected to each other with a gap of about several cm (for example, less than 5 cm) by a fixing member or the like, they are included in the connection. Further, the panel row R forms a panel row group G by being multiple placed at predetermined intervals in a north-south direction. The panel row R in the present embodiment is formed by six solar panels 50 connected in the east-west direction. Further, the panel row group G is formed by six panels rows R arranged in north-south direction.

The distance between the panel rows R adjacent to each other in the panel row group G is the east-west passage P1 extending in the east-west direction.

Further, of the six panels column R, the most southern placement panels column is the front panel column (end panel columns) Rf, panel columns arranged closest north, rear panel column (end panel columns ) Rr. Between the front end panel row Rf and the rear end panel row Rr, four panel rows R arranged in the north-south direction are arranged.

An east-west passage P1 is formed between the four panel rows R arranged between the front end panel row Rf and the rear end panel row Rr. Further, an east-west passage P1 is formed between the front end panel row Rf and the panel row R on the north side of the front end panel row Rf. Further, an east-west passage P1 is formed between the rear end panel row Rr and the panel row R on the south side of the rear end panel row Rr.

The front end panel row Rf is arranged along the south end edge 4S, which is the outer peripheral edge on the south side of the rectangular region 3a. The width W1 between the front end panel row Rf and the south end edge 4S is formed to be smaller than the width W2 of the east-west passage P1. In the present embodiment, the width W1 between the front end panel row Rf and the south end edge 4S is, for example, about 50 to 140 mm, and the width W2 of the east-west passage P1 is about 200 to 300 mm. Further, the rear end panel row Rr is arranged along the northern end edge 4N which is the outer peripheral edge on the north side of the rectangular region 3a. The width W3 between the rear end panel row Rr and the north end edge 4N is formed to be smaller than the width W2 of the east-west passage P1. In the present embodiment, the width W3 between the rear end panel row Rr and the north end edge 4N is, for example, about 100 to 180 mm. The width W1 between the front end panel row Rf and the south end edge 4S is a horizontal distance from the virtual vertical plane passing through the south end edge 4S to the front end panel row Rf. The width W3 between the rear edge panel row Rr and the northern edge 4N is the horizontal distance from the virtual vertical plane passing through the northern edge 4N to the rear edge panel row Rr.

A north-south passage P2 extending in the north-south direction is formed between at least one of the eastern and western edges of the panel row group G and the outer peripheral edge 4 of the rectangular region 3a. The north-south passage P2 communicates with the east-west passage P1. In the present embodiment, the western side edge GW of the panel row group G substantially coincides with the western edge 4W which is the outer peripheral edge on the west side in a plan view. On the other hand, the east side side edge GE of the panel row group G is arranged at a predetermined distance from the east end edge 4E which is the outer peripheral edge on the east side. The north-south passage P2 is formed by the distance between the side edge GE on the east side of the panel row group G and the east end edge 4E. The width W4 of the north-south passage P2 in the present embodiment is formed wider than the width of the east-west passage P1, for example, having a width of about 250 to 600 mm. The width W4 of the north-south passage P2 is a horizontal distance from the eastern side edge of the panel row group G to the virtual vertical plane passing through the eastern end edge 4E.

The flat roof 3 is provided with an elevating means leading downstairs from the north-south passage P2. In the present embodiment, a ladder La (see FIG. 1) that extends downstairs beyond the parapet 6 is provided on the eastern end edge 4E of the flat roof 3.
