Description

  The present invention relates to a solar cell panel fixture used for installing a solar cell panel on a folded plate roof.

  Since folded plate roofs of warehouses and factories have a relatively large area, solar cell panels may be installed on the roof using this. When installing a solar cell panel on the folded plate roof, it is common to use a fixture that is fixed to the goby portion of the folded plate roof. As such a fixing tool, for example, as in Patent Documents 1 and 2, a pair of left and right holding pieces each provided with a fastening portion fixed by a bolt and a holding portion for holding the goby portion, and protruding upward from the holding piece The structure provided with the mounting bolt to do is proposed. Here, the sandwiching piece is fixed to the goby portion of the folded plate roof, and is strongly affected by rain and wind outdoors. Therefore, strength and rigidity to withstand this are indispensable. Therefore, the sandwiching piece having the conventional configuration is formed into a complicated bent shape by bending a metal plate, and desired shape and rigidity can be exhibited by this shape effect.

  Furthermore, in the above-described conventional configuration, a mounting plate piece having a hole through which the mounting bolt is inserted is disposed on the clamping piece fixed to the goby portion, and the side end portion of the solar cell panel is mounted on the plate piece, Furthermore, a holding plate piece having a hole through which the mounting bolt is inserted is disposed on the side end portion of the solar cell panel. Then, the holding plate piece is pressed against the side end portion of the solar cell panel from above by screwing a nut into a mounting bolt protruding upward from the hole of the holding plate piece. In this way, the solar cell panel is fixed.

  In the fixture of the conventional configuration described above, the clamping piece made of metal plate is formed into a complicated form in order to ensure strength and rigidity, the manufacturing process is complicated, and the manufacturing cost increases. Had the problem of doing.

  Moreover, since the solar cell panel is provided in various panel thicknesses, there is a demand for a fixture that can be installed corresponding to these. The above-described conventional fixture has a mounting plate piece and a holding plate piece that sandwich and fix the side end portion of the solar cell panel up and down, so that the solar cell panel can be attached depending on the length of the mounting bolt. The panel thickness is determined. For this reason, a configuration in which relatively long mounting bolts are arranged so that solar cell panels having various panel thicknesses can be installed has been common. However, when a thin plate-like solar cell panel is installed on a relatively long mounting bolt, a portion of the mounting bolt that protrudes upward from the solar cell panel (holding plate piece) becomes longer. Such protruding portions of the mounting bolts cast a shadow on the solar cell panel. Since a solar cell panel is formed by arranging a plurality of cells vertically and horizontally, the electromotive force of a cell having a shadow is lower than that of a cell having no other shadow. Thus, when a difference in electromotive force occurs between cells, there arises a problem that the power generation efficiency of the entire solar battery panel is lowered, and there is a possibility of causing a failure.

  In order to solve the problem that the electromotive force is different between the cells, it is necessary to shorten the portion of the mounting bolt that protrudes upward from the solar cell panel (holding plate piece) as much as possible. For this, a fixture having a mounting bolt having a length corresponding to the panel thickness of the solar cell panel must be used. However, this loses the advantage of being able to handle solar panel panels of various panel thicknesses. Furthermore, the conventional configuration is a fixture having a complicated structure as described above, and in addition to this, if mounting bolts of various lengths are appropriately disposed, the manufacturing process becomes more complicated and the time required for the manufacturing is increased. There is also a problem that the cost increases.

  The present invention is an attempt to solve the above-described problems, and can reduce the manufacturing cost and various panels while suppressing the generation efficiency drop and the failure due to the shadow on the solar cell panel. The present invention proposes a solar panel fixing tool capable of installing a thick solar panel.

  The present invention relates to a solar cell panel fixture for installing and fixing a solar cell panel on a folded plate roof, a sandwiching portion having a substantially U-shaped cross section for sandwiching a goby portion of the folded plate roof from the side, and the sandwiching portion A fastening portion extending upward from the base, a pedestal portion provided on the fastening portion, on which a side end portion of the solar cell panel is mounted, and projecting upward from a substantially center of the pedestal portion, A projecting column portion that defines an installation interval between adjacent solar cell panels mounted on the unit, and is formed integrally with a fixed fixture main body and a clamping portion of the fixed fixture main body, and the goby portion A clamp part having a substantially U-shaped cross-section for clamping from the side, a fastening part facing the fastening part of the fixing tool main body, an integrally molded fixing tool sub body, and a fastening part of the fixing tool main body, The fastening part of the fixing tool sub-body is fastened, and both clamping parts are moved from the left and right sides through the fastening action. Left and right screw rods that are pressed against each other and fixed to each other, a panel fixing screw rod that is screwed from above into a vertical screw hole formed in the protruding pillar portion of the fixture main body, and the panel A side end portion of the solar cell panel mounted on the base portion of the fixing tool main body by including a through-hole through which the fixing screw rod penetrates and screwing the screw rod into the screw hole of the protruding column portion And a plate-shaped holding piece that holds the plate from above. Here, as the fixing tool main body and the fixing tool sub-body which are integrally formed, those integrally formed by casting, forging, press molding, injection molding, etc. are suitable, and the metal formed by these forming methods Made of plastic or resin.

  In such a configuration, the fixing tool main body and the fixing tool sub-body are integrally formed, and can be formed without the need for a processing step for forming a complicated bent shape as in the conventional configuration described above. Therefore, the time and cost required for manufacturing can be reduced. And in the structure of this invention, since the base part which mounts the side edge part of a solar cell panel is integrally molded by the fixture main body, compared with the above-mentioned conventional structure, there are few parts and manufacturing cost. Can be reduced.

  Furthermore, in the configuration of the present invention, the fixing body has a protruding column portion protruding from the pedestal portion, and a screw rod is screwed into the screw hole of the protruding column portion from above. The part of the bag protruding on the solar cell panel (holding piece) can be shortened. Thereby, it can suppress that a shadow produces on a solar cell panel by the said protrusion part of a screw rod, and can suppress the electric power generation efficiency fall of a solar cell panel by this shadow, and generation | occurrence | production of a failure. The panel fixing screw rod is a member separate from the fixing tool main body, and therefore, a panel having a length corresponding to the panel thickness of the solar cell panel can be prepared and easily replaced.

  Moreover, in the structure of this invention, the side edge part of two adjacent solar cell panels can be mounted on a base part, and can be hold | maintained. And a solar cell panel can be easily positioned by a fixed space | interval (installation space | interval) by arrange | positioning the side edge of an adjacent solar cell panel in contact with the protrusion pillar part, respectively. As a result, when installing a plurality of solar cell panels side by side, the solar cell panels can be easily positioned and installed at regular intervals (installation intervals), and the workability of the installation work can be improved. .

  In the above-described fixture for solar cell panel according to the present invention, a configuration is proposed in which the fixture main body and the fixture sub-body are integrally formed by casting.

  According to such a configuration, the fixture main body and the fixture sub-body can be easily formed into a relatively thick wall shape having desired strength and rigidity without using a complicated bending shape as in the conventional configuration described above. Can be molded. Here, in casting molding, each part of the fixing tool main body and the fixing tool sub-body can be formed with an appropriate thickness due to easy formation of a desired quality by forming to a certain thickness. Therefore, according to this configuration, it is possible to reduce the time and cost required for manufacturing by casting while having desired strength and rigidity, and thus the above-described operational effects of the present invention are further improved.

  In the solar cell panel fixture according to the present invention described above, the protruding column portion mainly composed of the fixture is configured such that the height thereof is the same as or lower than the panel thickness of the solar cell panel. Is proposed.

  According to such a configuration, the head of the screw rod for fixing the panel protrudes on the solar cell panel (holding piece), and the protruding portion can be made as short as possible. Therefore, it is possible to suppress as much as possible that the shadow caused by the protruding portion of the panel fixing screw rod is formed on the solar cell panel, and the effect of suppressing the reduction in power generation efficiency and the occurrence of failure due to the shadow is further stabilized. It is demonstrated. Here, when installing solar cell panels with various panel thicknesses, the protruding column portion can be installed with all solar cell panels by setting it to the same height as the thinnest panel thickness among them. At the same time, the effect of suppressing the reduction in power generation efficiency can occur.

A configuration that is designed to do so is proposed.

  Here, since the fixing tool main body is formed by casting, the fastening portion is formed relatively thick. Therefore, it is possible to form a screw hole directly in this fastening part, which is an advantage by casting. According to such a configuration, since the screw hole is formed in the fastening portion mainly of the fixture, a nut or the like for fixing the screw rod is not required, and the number of parts can be reduced. Further, since the fastening portion mainly of the fixture and the screw rod are directly screwed together, the fastening portion and the fastening portion of the fixture secondary body are fastened, so that the effect of maintaining the fastened state is excellent. Thus, by this fastening action, both the clamping parts can be held more stably in a fixed state in which the gore parts are clamped.

  In addition, when the fixing tool main body is what was shape | molded by casting, the fastening part is formed in comparatively thick shape. Therefore, it is easy to form a screw hole of a desired depth in the fastening portion, and the effect of maintaining the above-described fastening state is further improved.

  According to the fixture for solar cell panel of the present invention, as described above, the manufacturing cost can be reduced as compared with the conventional configuration. Furthermore, since the part which protrudes on the solar cell panel (holding piece) of the screw rod for panel fixation can be shortened, it can suppress that the shadow produced by this protrusion part arises on a solar cell panel, Reduction in power generation efficiency due to shadows and occurrence of failures can be suppressed.

Furthermore, by using the panel fixing bolts 25 having appropriate lengths according to the difference between the height of the protruding column portion 22 and the panel thickness of the solar cell panel 51, the solar cell panels 51 having various panel thicknesses are installed. can do. Here, the panel fixing bolt 25 is separate from the fixture main body 2 and the fixture sub body 3, and it is easy to prepare a panel having a different length.
Therefore, according to the configuration of the present embodiment, it is possible to install solar cell panels 51 having various panel thicknesses, and the above-described reduction in power generation efficiency and failure when any solar cell panel 51 is installed. The effect of suppressing the occurrence can be demonstrated.

  Moreover, the present Example is provided with the substantially square columnar protruding column part 22 and can position the solar cell panel 51 in the left-right direction so that the side end of the solar cell panel 51 comes into contact with the side wall surface. Therefore, the solar cell panel 51 can be easily positioned and installed at a constant interval (installation interval). Thereby, the solar cell panel 51 can be easily aligned and installed, and the workability of the installation work can be improved. In the present embodiment, the case where the solar cell panels 51 are arranged in the left-right direction has been described, but the solar cell panels 51 can also be arranged in the front-rear direction. When juxtaposed in the front-rear direction, the holding piece 26 is rotated 90 degrees with respect to the left-right direction. Even in the case where they are arranged side by side in the front-rear direction in this way, the effects of the above-described embodiment can be obtained as in the left-right direction.
