  In what was disclosed by patent document 1, a clamp etc. were mounted | worn with the mountain-shaped top part of the metal roof, the elongate support member was provided in this clamp, and the solar power generation device was mounted | worn with this support member. Because of such a configuration, the number of parts is large and assembly is troublesome. Therefore, the present invention aims to eliminate these drawbacks and defects and to make them versatile. That is, the problem (technical problem or purpose) to be solved by the present invention is to realize that the solar power generation apparatus can be easily and quickly attached, the work efficiency can be improved, and it can be provided at low cost. is there.

  Therefore, as a result of intensive studies and studies by the inventors to solve the above-mentioned problems, the invention according to claim 1 is based on a metal roof in which roof plate members are connected via a fastening portion and a base having a predetermined length in the longitudinal direction. The base material is arranged and fixed along a plurality of adjacent tightening portions of the metal roof, and has the same inclination direction and a predetermined interval. The photovoltaic power generation panel is disposed on an inclined receiving surface portion of the inclined table disposed at a position, and the inclined table is either perpendicular or identical to the longitudinal direction of the base material when viewed in plan. The above-described problems have been solved by using a solar power generation panel mounting apparatus that is arranged and fixed in the direction of.

  According to a second aspect of the present invention, in the solar power generation panel according to the first aspect, the tilt direction of the tilt base is orthogonal to the longitudinal direction of the plurality of base members and is supported by at least two of the base members. The above-described problems have been solved by using the attachment device. The invention of claim 3 is the solar power generation panel mounting device according to claim 1, wherein the tilting direction of the tilting table is arranged and fixed in the same direction with respect to the longitudinal direction of the plurality of base members. The above-mentioned problem was solved. The invention of claim 4 is the solar power generation panel mounting device according to claim 3, wherein the length of the base material in the longitudinal direction is a length of at least two of the inclined bases. Solved the problem.

  In the invention of claim 1, the main members for attaching the photovoltaic power generation panel to the metal roof are composed of only two members of the base material and the inclined base, and the configuration thereof is extremely simple, and the construction is simple and quick. it can. In detail, the base material is arranged and fixed along a plurality of tightening portions of the metal roof, and the tilting table is arranged so that the inclination direction is the same and parallel to the longitudinal direction of the base material. is there.

  And the photovoltaic power generation is attached to the inclined receiving surface portions of the plurality of inclined platforms, and by providing a plurality of these configurations, a set of photovoltaic power generation panels having an inclination is configured. In particular, the base material only needs to be arranged and fixed along the tightening portion of the metal roof. Therefore, the work can be performed easily and efficiently without bothering the mounting interval (pitch) of the base material. Even when the tilt base is mounted and fixed to the base material, the tilt direction is either the direction orthogonal to the longitudinal direction of the base material or the same direction, and can be easily installed. .

  In addition, when arranging and fixing the tilting direction of the tilting table perpendicular to the longitudinal direction of the base material fixed to the tightening portion of the metal roof, the tilting direction of the tilted receiving surface portion is set to the opposite direction. The inclination direction of the photovoltaic power generation panel can be reversed only by doing. Similarly, when the tilting direction of the tilt base is the same as the longitudinal direction of the base material, photovoltaic power generation can be achieved by simply tilting the tilting direction toward either end of the longitudinal direction of the base material. The inclination direction of the panel can be reversed. That is, the inclination direction of the photovoltaic power generation panel can be installed in any one of the four most preferable directions with respect to the metal roof, and can easily correspond to various conditions such as topography and environment. .

By arranging and fixing over the two base materials that are orthogonal to the longitudinal direction and in parallel with the inclined table, or by arranging the inclined receiving surface portion of the inclined table along the longitudinal direction of the base material. The inclination direction of the photovoltaic power generation panel attached in an inclined shape can be set very easily.

  In the invention of claim 2, since the tilt direction of the tilt receiving surface portion of the tilt table is orthogonal to the longitudinal direction of the plurality of base materials and is supported by at least two of the base materials, This is extremely suitable when the inclination direction of the photovoltaic panel is orthogonal to the longitudinal direction of the tightening portion. The tilting table is configured to be spanned over at least two base materials, and the tilting table not only installs the photovoltaic power generation panel in a tilted state but also supports members between the base materials arranged in parallel. Even if the space does not exist, it serves as a support member for supporting the photovoltaic power generation panel.

  In the invention according to claim 3, since the tilting table has a configuration in which the tilting direction of the tilt receiving surface portion is arranged and fixed in the same direction with respect to the longitudinal direction of the plurality of base members, the tilting direction of the photovoltaic power generation panel Can be very suitably used when the same direction is set in the longitudinal direction of the tightening portion. And since the inclination direction of an inclination receiving surface part and the longitudinal direction of a base material become the same direction, since the lower part of an inclination stand will be supported by a base material over the whole inclination table, in an inclination direction The strength of the support is improved, and the support of the photovoltaic power generation panel can be strengthened.

  According to a fourth aspect of the present invention, in addition to the configuration in which the tilting direction of the tilt receiving surface portion is arranged and fixed in the same direction with respect to the longitudinal direction of the plurality of base materials, Since the length is such that at least two tilt bases are arranged in series, at least two tilt bases are installed on the same base material and installed on the same surface. The tilted table can be installed in a very stable state. Furthermore, a high mounting accuracy can be achieved in front and rear.
