Description

  The present invention relates to a structure for installing a solar energy utilization device such as a solar battery panel installed on a roof of a building such as a house, and more particularly to a wiring structure of a solar energy utilization device.

  Conventionally, a frame for installing an installation on a roof such as a solar cell module has been configured with a crosspiece member, and there is a document disclosing a specific structure of the crosspiece member (for example, patent document). 1 and 2).

  When an installation on the roof such as a solar cell module is installed on the roof, it is necessary to fix the wiring material by tying various wiring materials such as electric cables, antenna cables, hot water pipes, etc. .

  Patent Document 1 discloses a structure of a crosspiece that accommodates and holds the wiring material of the installation on the roof and protects the wiring material from deterioration due to rainwater or the like. There has been proposed a structure in which a groove for forming a space is provided and a closing member is attached to the groove.

  Patent Document 2 discloses a method of fixing to a metal fitting using a binding band and a method of inserting and fixing to a cable support member having a substantially U-shaped cross section.

Japanese Patent No. 4679435 JP 2006-16790 A

  As described above, there has been a problem with the fixing of the wiring material of the installation on the roof, but the demand for further improvement has become apparent against the background of the rapid increase in demand for solar power generation in recent years.

  For example, in relation to Patent Document 1, since it is necessary to form a storage space that extends over the entire length of the crosspiece, the manufacturing cost of the crosspiece increases and the weight of the crosspiece increases. In particular, when a solar cell panel that is a heavy object is installed on a roof, the problem of weight increase should be emphasized.

  As another problem, the structure of Patent Document 1 requires both hands of holding the blocking member with respect to the groove with the other hand while holding the wiring member with one hand so that the wiring member does not fall out of the groove. Since it is a work form, there is room for improvement in workability in consideration of high-place work on the roof.

  On the other hand, even in the method using the binding band as disclosed in Patent Document 2, the operation of fastening the binding band is a two-handed operation, and a dedicated portion for fixing the binding band is provided on the crosspiece side. Measures such as are necessary.

  Moreover, in the form of the cable support member disclosed in Patent Document 2, there is a concern that the connection part cannot be inserted in, for example, a connection part of a wiring such as a connector. However, if a margin is provided so that the connecting portion can be inserted, there is a concern that most of the other wiring members are not firmly fixed to the cable support member and may fall off.

Next, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 explains the outline of the present invention, and shows a state in which a rectangular plate-like solar cell panel 2 is installed on a roof surface 10 of a roof 1. In addition to the solar cell panel 2, it is assumed that various solar energy utilization devices such as a solar water heater that uses solar heat are installed.

  As shown in FIGS. 1 and 2, foundation members 3 and 3 are installed at predetermined locations on the roof surface 10, and vertical beams 4 and 4 are bridged over the foundation members 3 and 3. A plurality of vertical bars 4 and 4 are arranged in parallel, and in the direction perpendicular to the vertical bars 4 and 4, the underwater side bar 5 and the upper waterside bar 6 are respectively connected to the vertical bars 4 and 4. It is bridged.

  Note that the terms “vertical” and “horizontal” in the vertical beam 4, the underwater side beam 5, and the upper waterside beam 6 are added for the sake of convenience in order to clearly indicate the relationship between them, and in a specific direction. It is not intended to limit. For example, the vertical and horizontal directions can be reversed, that is, “vertical beam” can be read as “horizontal beam” and “horizontal beam” can be read as “vertical beam”. For the sake of convenience, the lower side of the solar cell panel 2 that is inclined is defined as the water side and the higher side as the water side.

  With the above configuration, the roof surface 10 includes a plurality of vertical beams 4 and 4 arranged in parallel, a water-side horizontal beam 5 arranged in a direction orthogonal to the vertical beams 4 and 4, and a water-side surface. A frame 7 on the cross beam is constructed from the horizontal beam 6. The roof surface 10 of this embodiment is configured as a land roof that forms a substantially horizontal surface.

  The underwater side end 21 and the underwater side end 23 of the solar cell panel 2 are supported by the underwater side crosspiece 5 and the overwater side crosspiece 6 respectively. The solar cell panel 2 is inclined and arranged so as to have a gradient R in which the water-side height is lower than the water-side height.

  Further, as shown in FIG. 2, wiring members 30a and 30b are connected to the solar cell panels 2 and 2, and the electric power generated by the solar cell panels 2 and 2 is transmitted through the wiring members 30a and 30b. Is done. In addition, as a wiring material, the case where it is the cables for transmitting a control signal other than the power line for performing power transmission, the piping for distribute | circulating a fluid, etc. is assumed.

  In the longitudinal direction of the vertical beam 4, the solar cell panels 2, 2 are arranged with a predetermined distance D. For this reason, a space K that is not covered by the solar cell panel 2 is formed between the solar cell panels 2 and 2 adjacent in the longitudinal direction of the vertical rail 4.

  In this space K, since the wiring member 30a is not covered by the solar cell panel 2, there is a concern that the wiring member 30a is deteriorated by ultraviolet rays or rainwater.

  Therefore, a wiring frame 70 for accommodating the wiring material 30a is provided in the space K. As shown in FIGS. 3 and 4, the wiring frame 70 of the present embodiment is a long member attached by a fastener 72 (FIG. 4) to the side surface 41 of the vertical rail 4 and accommodates the wiring material 30 a. It is comprised with the member which has the accommodation space 73 for. The end of the accommodation space 73 in the longitudinal direction is open, and the wiring member 30 a is configured to pass through the accommodation space 73.

  The wiring frame 70 includes a fixed side surface portion 71a that is attached to the side surface 41 of the vertical rail 4, and an upper surface portion 71b and a lower surface portion 71c that protrude in a direction away from the vertical rail 4 at the upper and lower portions of the fixed side surface portion 71a. Have.

  A rising wall portion 71d is provided at an end of the lower surface portion 71c opposite to the fixed side surface portion 71a, and an engagement piece portion 71e is provided above the rising wall portion 71d.

  An engaging piece 71f is suspended from the end of the upper surface 71b opposite to the fixed side 71a.

  A gap is secured between the engagement piece portions 71e and 71f, and an opening 76 for inserting the wiring member 30a into the accommodation space 73 is formed by this gap.

  Once the wiring member 30a is inserted into the housing space 73, it is prevented from falling out of the wiring frame 70 through the opening 76 due to the presence of the rising wall portion 71d. From this point of view, it is preferable that the rising wall portion 71d is installed at a height of at least 1/3 at the vertical position between the upper surface portion 71b and the lower surface portion 71c of the wiring frame 70.

  Further, by providing the rising wall portion 71d in this way, it is possible to reliably prevent the wiring material 30a from dropping through the opening 76 in both cases where the wiring material 30a is thick and thin. In addition, it is possible to configure a large accommodation space 73 that can accommodate the connection portion 75 such as a connector.

  In addition, after inserting the wiring member 30 a into the accommodation space 73, a cover member 78 for closing the opening 76 is attached to the wiring frame 70.

  The cover member 78 has a closing surface portion 78a for closing the opening 76, and engaging piece portions 78e and 78f that project from the closing surface portion 78a and engage with the engaging piece portions 71e and 71f of the opening 76. Configured. When the engagement piece portions 78e and 78f are inserted into the opening 76, the engagement piece portions 78e and 78f bend so as to reduce the distance between them, and then elastically return to engage with the engagement piece portions 71e and 71f. Thereby, the cover member 78 is fitted to the wiring frame 70.

  Moreover, the wiring frame 70 and the cover member 78 are comprised by substantially the same length, and can be comprised by the same raw material (for example, aluminum molding material) as the vertical rail 4, or a resin molded product. Note that the cover member 78 may be configured to be shorter than the wiring frame 70, or a configuration in which the cover member 78 is configured to be shorter may be attached to a plurality of locations.

  Further, as shown in FIG. 2, the length of the wiring frame 70 is configured to be at least longer than the distance D between the solar cell panels 2 and 2 in the longitudinal direction of the vertical rail 4, whereby the wiring member 30a is made solar. In the space K not covered by the battery panel 2, the wiring member 30a is accommodated in the wiring frame 70, and deterioration of the wiring member 30a due to ultraviolet rays or rainwater can be prevented.

  More preferably, the wiring frame 70 is located above the water-side horizontal rail 5 covered by the solar cell panel 2 from the position P1 below the water-side horizontal rail 6 covered by the solar cell panel 2. It is preferable that the wiring member 30a can be accommodated between P2.

  In particular, as in the present embodiment, according to the configuration of the accommodation space 73 that is closed by attaching the cover member 78 to the wiring frame 70, it is possible to more reliably prevent the wiring member 30a from falling off, Since the connection part 75 of the wiring such as the connector is not exposed to the outside, the deterioration of the connection part 75, the rain water falling on the connection part 75, and unexpected troubles due to adhesion of dust and dust, etc. are also effective. This makes it possible to prevent such problems as prolonging the service life and prolonging the maintenance interval.

  As for positioning of the wiring frame 70 with respect to the vertical rail 4, for example, the corners of the fixed side surface portion 71 a and the upper surface portion 71 b of the wiring frame 70 are abutted against the protrusion 42 provided on the side surface 41 of the vertical rail 4. It can be considered that the positioning is carried out with the.

  As shown in FIG. 5, the protrusions 42 are configured as protrusions extending in the longitudinal direction of the vertical beam 4, so that the brackets 8 and 9 for fixing the water-side horizontal beam 5 and the water-side horizontal beam 6 are fixed. It is possible to have both a positioning function and a detent function.

  Further, as another embodiment different from the above example, as shown in a wiring frame 70A shown in FIG. 6A, an opening 76A through which the wiring material 30a passes is vertically formed of a soft material (rubber, resin, etc.). A pair of closing members 77a and 77b are provided to form the cover member 78A, and the closing members 77a and 77b are bent to form a gap between them, allowing the wiring member 30a to pass therethrough, and the wiring member 30a to pass into the accommodation space 73A. It is also possible to conceive the form.

  Note that, as in the cover member 78B shown in FIG. 6B, a gap for allowing the wiring member 30a to pass through may be formed by providing a single piece of the closing member 77c and bending the closing member 77c.

  Furthermore, the shape of the wiring frame 70 can be considered in addition to the above-described embodiment. For example, as shown in FIG. 4, it is conceivable that the wiring frame 70 is formed in a rectangular tube shape so that the cross section of the wiring frame 70 forms a square shape, or a round tube or an elliptic tube.

As described above, the present invention can be implemented.

  Thereby, as shown in FIG. 3 and FIG. 4, the wiring frame 70 is formed of a member different from the vertical beam 4, and thus the manufacturing cost of the vertical beam 4 can be suppressed at a low cost. In addition, since the wiring frame 70 is attached only to the space K, it is possible to suppress an increase in the weight of the vertical rail 4 including the wiring frame 70.

  In addition, a series of openings 76 are formed in the wiring frame 70 in the longitudinal direction of the wiring frame 70 for inserting the wiring material 70 into the accommodation space 73 inside the wiring frame 70 from the outside of the wiring frame 70.

  Preferably, the housing space 73 of the wiring frame 70 includes a fixed side surface 71a that is attached to the side surface of the vertical rail 4, an upper surface portion 71b that protrudes in a direction away from the vertical rail 4 at an upper portion of the fixed side surface portion 71a, The lower surface portion 71c protrudes in a direction away from the vertical rail 4 at the lower portion of the side surface portion 71a, and the rising wall portion 71d rising from the end opposite to the fixed side surface portion 71a in the lower surface portion 71c is configured. A series of openings 76 for inserting the wiring member 30a from the outside are formed between the upper surface portion 71b and the rising wall portion 71d.

  Thereby, the wiring member 30a can be accommodated in the accommodating space 73 through the opening 76, and once the wiring member 30a is inserted into the accommodating space 73, the wiring frame through the opening 76 due to the presence of the rising wall portion 71d. It is prevented from falling out of 70. Further, by providing the rising wall portion 71d, it is possible to reliably prevent the wiring material 30a from dropping through the opening 76 in any case where the wiring material 30a is thick or thin. In addition, it is possible to configure a large accommodation space 73 that can accommodate the connection portion 75 such as a connector.

  Further, the opening 76 is closed by the cover member 78 and the accommodation space 73 is closed.

  As a result, it is possible to more reliably prevent the wiring member 30a from falling off, and the connection portion 75 of the wiring such as a connector is not exposed to the outside. It is also possible to effectively prevent deterioration of the connecting portion 75, rainwater falling on the connecting portion 75, and unexpected troubles due to the adhesion of dust and dust, extending the service life and reducing maintenance intervals. It becomes possible to achieve a longer period. Further, when attaching the cover member 78 formed of a separate member to the wiring frame 70, the wiring member 30a is accommodated in the accommodating space 73 in advance, so that the covering member 78 can be easily held without holding the wiring member 30a by hand. Can be attached.

  Further, the cover member 78 is configured to be fitted to the opening 76.

  Thereby, the attachment work of the cover member 78 with respect to the wiring frame 70 can be performed easily.

  Further, as shown in FIG. 6A, the cover member 78A is composed of closing members 77a and 77b made of a soft material provided in the opening 76, and the opening members 76a and 77b are elastically deformed so that A gap is formed to allow the wiring material 30a to pass therethrough.

  Thereby, the attachment work of the cover member 78A can be made unnecessary, and the work efficiency can be improved.

  Further, as shown in FIGS. 4 and 5, the wiring frame 70 can be positioned with respect to the vertical rail 4 by abutting a part of the wiring frame 70 against the protrusion 42 provided on the side surface 41 of the vertical rail 4. It shall be configured.
