Summary of the Invention

Problems to be Solved by the Invention

[0004] In this type of roof structure, it is necessary to realize waterproof performance and the like while simplifying the structure.

Means for Solving the Problems

[0005] The roof structure for solving the above problems is a roof structure in which panels are arranged in a first direction and a second direction intersecting the first direction, and a gasket is interposed between the panels. The gasket includes a main body portion disposed between adjacent panels. The main body portion includes an engagement support groove into which an edge portion of one of the adjacent panels is engaged and an engagement support groove into which an edge portion of the other panel is engaged. The gasket extending in the first direction is a first gasket, and the gasket extending in the second direction is a second gasket. At an intersection where the first gasket and the second gasket overlap, the first gasket includes a first recess having an open end above the main body portion, and the second gasket includes a second recess having an open end below the main body portion. The first recess and the second recess are engaged with each other.

[0006] Further, the gasket for solving the above problems is a gasket disposed between panels arranged in a first direction and a second direction intersecting the first direction. The gasket includes a main body portion disposed between adjacent panels. The main body portion includes an engagement support groove into which an edge portion of one of the adjacent panels is engaged and an engagement support groove into which an edge portion of the other panel is engaged. The main body portion has a recess having an open end on the upper side or the lower side.

[0007] According to the above configuration, by engaging the edge portions of adjacent panels with the engagement support grooves of the gasket, a roof structure can be configured with a gasket interposed between adjacent panels. Thereby, the roof structure can have a simple structure.

[0008] Further, by engaging the first recess of the first gasket and the second recess of the second gasket, they can be easily crossed. And the height difference between the intersecting first gasket and second gasket can be suppressed.

[0009] In the first gasket and the second gasket, the surface including the first opening end of the first recess and the second opening end of the second recess is the insertion surface, the surface on the side opposite to the insertion surface is the base end surface, and in the intersection portion, the insertion surface of one of the first gasket and the second gasket and the base end surface of the other gasket may be configured to be located at the same height. According to the above configuration, the heights of the first gasket and the second gasket can be made uniform.

[0010] The engaging support groove may be configured to include an elastic piece on the bottom surface against which the end surface of the panel abuts. According to the above configuration, the end surface of the panel can be pressed against the bottom surface of the engaging support groove. Thereby, the waterproof performance at the joint portion of the panel can be enhanced.

[0011] Either one of the first gasket and the second gasket may be configured to be abutted and supported on the upper surface of the crossbar. According to the above configuration, the panel assembly in which panels are arranged via the gaskets can be stably supported by the crossbar.

[0012] The panel is, for example, a solar power generation panel. According to the above configuration, a roof structure can be constituted by the solar power generation panel.

MODE FOR CARRYING OUT THE INVENTION

[0015] Hereinafter, a roof structure of a carport to which the present invention is applied will be described with reference to FIGS. 1 to 17. <Description of the carport> As shown in FIGS. 1 and 2, the carport 1 is a parking lot with a simple structure and is a parking lot equipped with charging facilities for the electric vehicle 1a. The carport 1 includes a support column portion 2 and a roof structure 3 as an upper structure installed on the upper portion of the support column portion 2.

[0016] In the present embodiment, the roof structure 3 is supported by two support column portions 2. The roof structure 3 has a solar power generation panel 4 installed thereon as a panel. The roof structure 3 includes a first roof portion 5 and a second roof portion 6. The first roof portion 5 and the second roof portion 6 form a V shape. That is, the first roof portion 5 includes a base end portion 5a and a tip end portion 5b opposite to the base end portion 5a. The tip end portion 5b is located above the base end portion 5a. The second roof portion 6 also includes a base end portion 6a and a tip end portion 6b opposite to the base end portion 6a. The tip end portion 6b is located above the base end portion 6a. The base end portion 5a of the first roof portion 5 and the base end portion 6a of the second roof portion 6 are connected to form a V-shaped valley portion. The support column portion 2 hangs down from the valley portion. Each of the roof portions 5 and 6 is configured to be connected to the upper portion of the support column portion 2 by a cross member 7. Such a carport 1 has equipment parts such as a transformer, a storage battery, a lighting fixture, a display panel, and a charging device installed in a roof inner portion or the like (not shown).

[0017] <Roof structure> FIGS. 2 and 3 show a roof structure 10 that constitutes the first roof portion 5 and the second roof portion 6. The roof structure 10 includes beam portions 11 extending from the upper ends of the respective two support column portions 2. The beam portions 11 are supported by the support column portions 2 by cross members 7. The two beam portions 11 are parallel to each other, and a plurality of horizontal crossbars 13 are arranged in parallel with each other from the tip end toward the base end side. And a plurality of solar power generation panels 4 are arranged on the horizontal crossbars 13.

[0018] Each photovoltaic panel 4 has a rectangular plate shape. In each photovoltaic panel 4, solar cells are sandwiched between a cover glass and a backsheet, and the periphery is sealed by a frame. And on the back surface, power extraction terminals and the like are provided. In the present embodiment, for example, four photovoltaic panels 4 are arranged in the X direction (first direction) and five in the Y direction (second direction). The joints of adjacent photovoltaic panels 4 in the Y direction are located on the horizontal crossbar 13.

[0019] <First Embodiment - Gasket -> As shown in FIG. 4, a gasket is interposed between the photovoltaic panels 4. Here, the gasket extending in the X direction and parallel to the horizontal crossbar 13 is the first gasket 14a, and the gasket extending in the Y direction and parallel to the beam portion 11 is the second gasket 14b. The gaskets 14a and 14b are, as an example, extruded products made of an elastic resin material.

[0020] As shown in FIG. 5, the first gasket 14a includes a first main body portion 15a, a first engagement support groove 16a, a first upper piece portion 17a, and a first lower piece portion 18a. A first upper piece portion 17a is formed on the upper side of the first main body portion 15a, and a first lower piece portion 18a is formed on the lower side of the first main body portion 15a. Each of the first upper piece portion 17a and the first lower piece portion 18a projects from the opposite side surfaces of the first main body portion 15a. The surface of the first upper piece portion 17a is formed as a smoother surface than the surface of the first lower piece portion 18a. Also, the surface of the first lower piece portion 18a is formed to bulge more than the surface of the first upper piece portion 17a.

[0021] The first upper piece portion 17a, the first lower piece portion 18a, and the side surfaces of the first main body portion 15a form a first engagement support groove 16a having a bottomed concave shape. The side surfaces of the first main body portion 15a form the bottom surface of the first engagement support groove 16a. The first engagement support grooves 16a are provided on both sides sandwiching the first main body portion 15a.

[0022] The side surface of the first main body portion 15a that constitutes the bottom surface of the first engagement support groove 16a is provided with first elastic pieces 19a that are spaced apart from each other in the vertical direction. The first elastic pieces 19a are configured such that their tips face the first upper piece portion 17a. Also, the first elastic pieces 19a have a height lower than the depth of the first engagement support groove 16a.

[0023] The first gasket 14a has a first recess 21a formed at a position that is the intersection with the second gasket 14b. The first recess 21a is formed by cutting from the first upper piece portion 17a to an intermediate position of the first main body portion 15a. That is, the first recess 21a has a depth up to an intermediate position between the first upper piece portion 17a and the first lower piece portion 18a. The first recess 21a is a bottomed recess having a first opening end in the first upper piece portion 17a. The surface of the first upper piece portion 17a becomes an insertion surface into which the second gasket 14b is inserted when forming the intersection with the second gasket 14b. The first recess 21a is wider at the opening end than at the bottom surface, that is, trapezoidal in shape, facilitating engagement with the second recess 21b of the second gasket 14b.

[0024] The second gasket 14b is a gasket disposed above the first gasket 14a. The second gasket 14b also has a configuration substantially similar to that of the first gasket 14a. That is, the second gasket 14b includes a second main body portion 15b, a second engagement support groove 16b, a second upper piece portion 17b, and a second lower piece portion 18b. The surface of the second upper piece portion 17b is configured as a smoother surface than the surface of the second lower piece portion 18b. Also, the surface of the second lower piece portion 18b is configured to bulge more than the surface of the second upper piece portion 17b.

[0025] The side surfaces of the second upper piece portion 17b and the second lower piece portion 18b and the second main body portion 15b constitute a second engagement support groove 16b having a bottomed concave shape. The side surface of the second main body portion 15b constitutes the bottom surface of the second engagement support groove 16b. The second engagement support grooves 16b are provided on both sides with the second main body portion 15b interposed therebetween. The side surface of the second main body portion 15b that constitutes the bottom surface of the second engagement support groove 16b is provided with second elastic pieces 19b that are spaced apart from each other in the vertical direction.

[0026] The second gasket 14b has a second recess 21b formed at a position that intersects with the first gasket 14a. The second recess 21b is formed by notching from the second lower piece portion 18b to an intermediate position of the second main body portion 15b. That is, the second recess 21b has a depth up to an intermediate position between the second upper piece portion 17b and the second lower piece portion 18b. The second recess 21b is a bottomed recess having a second opening end in the second lower piece portion 18b. The surface of the second lower piece portion 18b becomes an insertion surface into which the second gasket 14b is inserted when forming an intersection portion with the first gasket 14a. The second recess 21b has a wider opening end than the bottom surface, that is, has a trapezoidal shape, which facilitates engagement with the first recess 21a of the first gasket 14a.

[0027] Thus, the first gasket 14a and the second gasket 14b have the same configuration, and differ in that the first recess 21a is an upward recess while the second recess 21b is a downward recess. The first recess 21a and the second recess 21b have a depth from the surface to an intermediate position between the upper piece portions 17a, 17b and the lower piece portions 18a, 18b, and have the same depth.

[0028] FIG. 6 shows an intersection portion between the first gasket 14a and the second gasket 14b. The first gasket 14a is positioned below the second gasket 14b, and the second gasket 14b is positioned above the first gasket 14a. At the intersection portion, the first recess 21a and the second recess 21b are engaged with each other. The first recess 21a and the second recess 21b have a depth from the surface to an intermediate position between the upper piece portions 17a, 17b and the lower piece portions 18a, 18b, and have the same depth. Therefore, the first gasket 14a and the second gasket 14b are positioned at the same height even when they are intersected.

[0029] That is, when the roof structure 10 is viewed from above, the surfaces (insertion surfaces) of the first upper pieces 17a extending from both sides of the opening end of the first recess 21a in the first gasket 14a and the surfaces (base end surfaces) of the second upper pieces 17b in the second gasket 14b are at the same height. Also, when the roof structure 10 is viewed from below, the surfaces (insertion surfaces) of the second lower pieces 18b extending from both sides of the opening end of the second recess 21b in the second gasket 14b and the surfaces (base end surfaces) of the second lower pieces 18a in the first gasket 14a are at the same height.

[0030] As shown in FIG. 7, the edges of the solar power generation panels 4 are engaged with the engagement support grooves 16a and 16b of the gaskets 14a and 14b. The end faces of the solar power generation panels 4 are pressed against the elastic pieces 19a and 19b of the engagement support grooves 16a and 16b. Thereby, the edges of the solar power generation panels 4 are protected by the gaskets 14a and 14, and the watertightness from the front surface to the back surface is maintained.

[0031] As shown in FIGS. 8 and 9, the surfaces of the upper pieces 17a and 17b of the gaskets 14a and 14b are configured as smooth surfaces. Therefore, the surface of the roof structure 10 has a small step between the surface of the solar power generation panel 4 and the surfaces of the upper pieces 17a and 17b, and smoothness can be ensured. On the other hand, the surfaces of the lower pieces 18a and 18b are configured to bulge. The first lower piece 18a in the first gasket 14a is in contact with the upper surface of the horizontal crossbar 13.

[0032] <Assembly method> FIGS. 10 and 11 are diagrams for explaining the first assembly method. First, a gasket assembly 32 is configured by combining the first recess 21a of the first gasket 14a and the second recess 21b of the second gasket 14b to provide an intersection. On the other hand, a plurality of solar power generation panels 4 are arranged in the X direction and the Y direction. At this time, a gap 31 for arranging the gaskets 14a and 14b is provided between adjacent solar power generation panels 4. After that, the gasket assembly 32 is arranged in the portion of the gap 31, and the positions of the gaskets 14a and 14b and the positions of the arranged solar power generation panels 4 are finely adjusted so that the edges of the solar power generation panels 4 are engaged with the engagement support grooves 16a and 16b.

[0033] Figures 12, 13, and 14 are diagrams for explaining the second assembly method. A plurality of photovoltaic panels 4 are arranged in the X direction and the Y direction. At this time, a gap 31 for arranging gaskets 14a and 14b is provided between adjacent photovoltaic panels 4. Then, the first gasket 14a is arranged in the gap 31. Next, the second gasket 14b is arranged in the gap 31. At this time, the first recess 21a and the second recess 21b are engaged. Further, the positions of the gaskets 14a and 14b and the positions of the arranged photovoltaic panels 4 are finely adjusted so that the edges of the photovoltaic panels 4 are engaged with the engagement support grooves 16a and 16b.

[0034] <Effect of the First Embodiment> The effect of the first embodiment will be described. (1-1) The roof structure 10 is configured by engaging the edges of adjacent photovoltaic panels 4 with the engagement support grooves 16a and 16b of the gaskets 14a and 14b. In this way, the roof structure 10 can be configured with a simple structure.

[0035] (1-2) The roof structure 10 can be configured by engaging the first recess 21a and the second recess 21b with the intersecting portion where the first gasket 14a and the second gasket 14b overlap. Thereby, the height difference between the intersecting first gasket 14a and second gasket 14b can be suppressed.

[0036] (1-3) Specifically, the first concave portion 21a is formed by cutting out from the intermediate position between the first lower piece portion 18a to the first main body portion 15a. The second concave portion 21b is also formed by cutting out from the intermediate position between the second lower piece portion 18b to the second main body portion 15b. As a result, when the roof structure 10 is viewed from above, the surface (insertion surface) of the first upper piece portion 17a extending from both sides of the opening end of the first concave portion 21a in the first gasket 14a and the surface (base end surface) of the second upper piece portion 17b in the second gasket 14b are substantially at the same height. Also, when the roof structure 10 is viewed from below, the surface (insertion surface) of the second lower piece portion 18b extending from both sides of the opening end of the second concave portion 21b in the second gasket 14b and the surface (base end surface) of the second lower piece portion 18a in the first gasket 14a are substantially at the same height.

[0037] Therefore, in the roof structure 10, the upper surface can be configured to be substantially flat. Therefore, it becomes difficult for foreign matters such as dust to accumulate in stepped portions or the like. Also, the lower surface can be brought into contact with the upper surface of the horizontal crossbar 13. Thereby, the assembly of the photovoltaic panel 4 and the gaskets 14a, 14b is stably supported by the horizontal crossbar 13.

[0038] (1-4) The elastic pieces 19a, 19b can be pressed against the bottom surface of the end face of the photovoltaic panel 4 so as to be displaced. Thereby, the watertightness at the joint portion of the photovoltaic panel 4 can be enhanced.

[0039] (1-5) The photovoltaic panel 4 is provided with power extraction terminals and the like on the back surface. In this regard, since the joint portion of the photovoltaic panel 4 is made watertight by the gaskets 14a, 14b, it is possible to prevent the extraction terminals and the like from being soiled.

[0040] <Second Embodiment - Gasket-> In the second embodiment, the first gasket 14a does not include the first lower piece portion 18a. In this case, the first engagement support groove 16a is not a bottomed concave shape but an L-shaped groove. The position of the lower end of the first main body portion 15a may be at the same height as the back surface of the photovoltaic panel 4, or may be at a height such that the position of the lower end is located in the middle in the thickness direction of the photovoltaic panel 4.

[0041] The second gasket 14b also does not include the second lower piece portion 18a. Also in this case, the second engagement support groove 16b is not a bottomed concave shape but an L-shaped groove. The position of the lower end of the second main body portion 15b may be at the same height as the back surface of the photovoltaic panel 4, or may be at a height such that the position of the lower end is located in the middle in the thickness direction of the photovoltaic panel 4.

[0042] <Effect of the Second Embodiment> The effect of the second embodiment will be described. (2-1) Since the engagement support grooves 16a and 16b are L-shaped grooves, the configuration is simplified. And the engagement operation with the end portion of the photovoltaic panel 4 becomes easy. Therefore, the assembly of the roof structure 10 also becomes easy.

[0043] <Modification Examples of the First Embodiment and the Second Embodiment> The embodiment can be implemented with the following modifications. The embodiment and the following modification examples can be implemented in combination with each other within a technically non-conflicting range.

[0044] · Not all of the roof portion of the roof structure 10 need be constituted by the photovoltaic panels 4. For example, a combination of a normal roof panel and the photovoltaic panels 4 may be used. For example, in areas with poor sunlight, normal roof panels may be used.

[0045] · The support structure of the assembly of the photovoltaic panel 4 and the gaskets 14a and 14b may be a structure other than the structure supported by the horizontal crossbar 13. · In the engagement support grooves 16a and 16b, the elastic pieces 19a and 19b may be omitted. Also, the number of elastic pieces 19a and 19b provided in each engagement support groove 16a and 16b may be one or a plurality.

[0046] · When the roof structure 10 is viewed from above, the surface (insertion surface) of the first upper piece portion 17a extending from both sides of the opening end of the first recess 21a in the first gasket 14a may be a structure in which the surface (base end surface) of the second upper piece portion 17b in the second gasket 14b protrudes. Also, when the roof structure 10 is viewed from below, the surface (base end surface) of the first lower piece portion 18a in the first gasket 14a may protrude with respect to the surface (insertion surface) of the second lower piece portion 18b extending from both sides of the opening end of the second recess 21b in the second gasket 14b.

[0047] · The first gasket 14a may be structured to omit the first recess 21a. Also, the second gasket 14b may also be configured to omit the second recess 21b. That is, the roof structure 10 may omit either one of the first recess 21a and the second recess 21b. Also, both the first recess 21a and the second recess 21b may be omitted.
