Description

The present invention relates to an installation structure of a functional panel.

Conventionally, a structure for supporting a photovoltaic power generation panel against the roof surface of a building has been known. For example, Patent Document 1 discloses a support stand that supports a photovoltaic power generation panel. This support pedestal includes a support column provided so as to project from the roof, a pair of vertical members supported by the support column, and a horizontal member erected on the vertical member.

Japanese Unexamined Patent Publication No. 2013-144917

As described in Patent Document 1, the photovoltaic power generation panel needs to be accurately positioned in order to be arranged and fixed at a predetermined position on the support pedestal, but since the support surface of the pedestal is inclined, the sun There is a problem that it is difficult to set the photovoltaic power generation panel at a fixed position and it takes time and effort for positioning work.

Therefore, an object of the present invention is to provide an installation structure of a functional panel in which a functional panel can be easily installed on a support stand.

The installation structure of the functional panels according to the present invention is provided on the roof surface in parallel with each other, is supported by a plurality of cross members constituting the support pedestal, and the plurality of functional panels are connected to each other. The functional panel row is provided with a positioning material provided so as to abut on one of the sides parallel to the cross member in the functional panel row on the roof surface, and the positioning material is a spread of the cross member. Extending along the existing direction, one positioning member is in contact with a plurality of functional panels constituting the functional panel row.

In this functional panel installation structure, since the positioning material is brought into contact with the functional panel row, the functional panels constituting the functional panel row can be easily positioned. Further, since one positioning material comes into contact with the plurality of functional panels, the plurality of functional panels can be positioned by one member (one positioning material). As described above, in the installation structure of the functional panel, the functional panel can be easily installed on the support stand.

In the two cross members adjacent to each other among the plurality of horizontal members, the support portion of the functional panel row in the horizontal member closer to the positioning member is lower in height than the support portion of the functional panel row in the other horizontal member. May be good. Even if the functional panel tends to slip off the horizontal lumber due to the height difference between the support parts of the horizontal lumber, the positioning material prevents the functional panel from slipping off and facilitates the positioning of the functional panel. It can be carried out.

The cross member and the positioning member may be supported by a plurality of vertical members provided so as to be orthogonal to the cross member and the positioning member in a plan view. In this way, since the vertical members are orthogonal to the horizontal members and the positioning members, it is possible to support a plurality of horizontal members and the positioning members by one vertical member, and the horizontal members and the positioning members can be supported by a small number of vertical members. Can be reasonably supported.

Further provided with a cable holding material spanned over a plurality of vertical members so as to be parallel to the horizontal member, the functional panel is a photovoltaic power generation panel, and the cable holding material electrically connects adjacent functional panels to each other. The cable may be held away from the roof surface. In this case, it is possible to prevent deterioration promoted by the coating of the cable coming into contact with the roof surface (particularly, a waterproof sheet laid on the roof surface).

The cable holding material may be provided in the vicinity of the cable connection portion in the functional panel. In this case, the looseness of the cable can be prevented, and the cable can be further prevented from coming into contact with the roof surface.

The connection portion of the cable in the functional panel may be provided on the water upper side of the functional panel which is inclined by being supported by the support portions of the cross members having different heights from each other. Here, on the water upper side of the functional panel, a wider space is secured below the functional panel than on the water lower side. Therefore, the cable connecting work and the cable fastening work to the cable holding material can be performed in a wide space below the functional panel, and the workability is improved.

The functional panel rows are formed in multiple stages, and the two functional panels located at one end of the functional panel rows adjacent to each other are electrically connected by a cable, and one end of the functional panel rows adjacent to each other is electrically connected. Of the functional panels located in, the cable connection in one functional panel is provided on the water side, the cable connection in the other functional panel is provided on the underwater side, and the water upper end in one functional panel. The portion and the underwater end of the other functional panel may face each other. In this case, the cable connection portion of the other functional panel can function as a relay point when connecting adjacent functional panel rows with a cable. By making the other function panel function as a relay point in this way, it is possible to suppress slackening of the cable when connecting adjacent function panel rows with a cable, and it is easy for the cable to come into contact with the roof surface. Can be prevented. Further, since the other function panel functions as a relay point, when the function panel rows adjacent to each other are connected by a cable, the separation dimension of the cable connection portion can be reduced. As a result, it is possible to avoid the trouble of exchanging a long cable or adding a cable when connecting the functional panel rows, and avoiding contact with the roof surface due to hanging.

Each of the plurality of vertical members is composed of one member, and each of the plurality of vertical members may support a plurality of stages of functional panel rows via horizontal members. In this case, a vertical member made of one member can support a plurality of rows of functional panels, and can rationally support the functional panels.

The functional panel rows are formed in a plurality of stages, each of the plurality of vertical members is composed of one member, and each of the plurality of vertical members may support the plurality of stages of the functional panel rows via the horizontal members. .. As described above, even when the functional panel rows are formed in a plurality of stages, the vertical members made of one member can support the functional panel rows in a plurality of stages, and the functional panels can be rationally supported.

The vertical member may be supported by column base members at both ends. In this case, the vertical member can be supported by the minimum necessary column base member, and the vertical member can be reasonably supported.

The functional panel may be fixed to the cross member by being sandwiched between the cross member and the fixture fastened to the cross member. In this case, the functional panel can be easily fixed to the cross member without drilling a hole in the functional panel. Further, when the functional panel is fixed by sandwiching it with a fixture, the installation position of the functional panel may shift depending on the position where the functional panel is sandwiched. In the present invention, since the functional panel can be positioned by the positioning material, the functional panel can be fixed at the correct position by the fixture even when the functional panel is fixed by the fixture.

According to the present invention, the functional panel can be easily installed on the support frame.

It is fixed at 31.

Two cross members 34 (see FIGS. 1 and 2) are assigned to each panel row R, and one is the front end portion of the panel row R (photovoltaic panel 50 constituting the panel row R). The other one is arranged on the side (underwater side, south side) and the other one on the rear end side (water upper side, north side), respectively. The plurality of cross members 34 are provided on the roof surface in parallel with each other. As shown in FIG. 5, at a predetermined position (near the long side of the photovoltaic power generation panel 50) of the cross member 34 on the rear end side of the pair of cross members 34, the rear end side of the photovoltaic power generation panel 50 A fixing piece 71 is attached to hold the unit at a predetermined height. That is, the fixing piece 71 is attached to the horizontal member 34 on the side farther from the positioning member 91, which will be described later, among the two horizontal members 34 assigned to one panel row R.

As shown in FIG. 4, the fixing piece 71 is a member having a substantially U-shaped cross section, and has a support portion 71a having an inclined surface and a front side surface portion that bends from the front end and the rear end of the support portion 34a and extends downward. It has a 71b and a rear side surface portion 71c. The inclination angle of the support portion 71a in the installed state is set to be the same angle as the installation angle of the photovoltaic power generation panel 50 (for example, about 5 degrees).

In the present embodiment, the angle formed by the folded-back portion 91c and the side portion 91b is set to an angle slightly larger than 90 degrees (for example, around 95 degrees), and the tip end side of the folded-back portion 91c is slightly open. With such a configuration, the workability of the photovoltaic power generation panel 50 can be improved. The angle between the folded-back portion 91c and the side portion 91b may be set to 90 degrees. In this case, the workability is slightly reduced, but the lifting prevention function of the front end portion of the photovoltaic power generation panel 50 is improved. be able to.

Further, as shown in FIGS. 3 and 5, the support pedestal 30 has a cable holding material 61 for holding a cable 51 (see FIG. 7A) for electrically connecting the photovoltaic power generation panels 50 to each other. It is installed. The cable holding member 61 is a long member having a substantially L-shaped cross section, and has a bottom portion 61a fixed to the vertical member 31 and a side portion 61b that bends from one end of the bottom portion 61a and stands upright. .. The upper end of the side 61b is slightly bent toward the bottom 61a for safety. The side portion 61b may be formed with, for example, a plurality of holes for inserting a binding band or the like used for holding the cable 51. Alternatively, the side portion 61b may be provided with a hook, a ring, or the like used to hold the cable 51.

The cable holding member 61 is placed (bridged) over a plurality of vertical members 31 so as to be parallel to the horizontal member 34, and has a bolt hole formed in the bottom portion 61a and an upper surface portion of the vertical member 31. It is fixed to the vertical member 31 by being fastened by a bolt 62a and a nut 62b inserted into a bolt hole formed in 31c. The cable holding material 61 is further north than the horizontal member 34 on the north side, and is in the vicinity of a junction box (cable connection portion) 52 (see FIG. 7A) provided on the back surface of the photovoltaic power generation panel 50, which will be described later. is set up.

The cables 51 of the two adjacent photovoltaic power generation panels 50 are connected via a coupler provided at the tip of each cable.

The front end side of the photovoltaic power generation panel 50 is placed on the support portion 34a of the horizontal member 34 on the side closer to the positioning member 91 of the two horizontal members 34 that support the panel row R. Further, the rear end side of the photovoltaic power generation panel 50 is a support portion of a fixing piece 71 attached to the cross member 34 on the side away from the positioning member 91 of the two cross members 34 supporting the panel row R. It is placed on 71a. The height of the support portion 34a of the cross member 34 on the side closer to the positioning member 91 is lower than that of the support portion 71a of the fixing piece 71. Therefore, the photovoltaic power generation panel 50 is maintained at a predetermined inclination angle by being supported by the support portion 34a of the cross member 34 and the support portion 71a of the fixed piece 71. As a result, in the photovoltaic power generation panel 50, the side close to the positioning material 91 is the underwater side, and the opposite side is the water upper side. The front end portion of the photovoltaic power generation panel 50 is inserted between the bottom portion 91a of the positioning member 91 and the folded portion 91c, and the front end surface is brought into contact with the side portion 91b of the positioning member 91 to be positioned in the longitudinal direction. ing.
