JP 2003-56147 A Japanese Patent No. 3352647

However, in Patent Document 1, since the folded plate roof has a gentle slope, dust, dust, dirt, etc. are likely to accumulate on the superposed portion of the solar cell panel frame material, and deterioration of the fixed portion (for example, the fastening bolt 31 etc.) There was a risk of damaging the design of the roof.
Further, in the structure of Patent Document 2, since the long members are arranged in the direction intersecting with the flow direction, there is a problem similar to the above that dust or soil that has entered between the panels or rainwater containing the same tends to stay. It was. In addition, since rainwater that has entered the long member has a flow path only in the lateral direction, dust and the like are more easily accumulated in the long member than the above.

  Therefore, the present inventors have an object of proposing a structure in which rainwater or the like does not stay on the crosspiece member even if there is water or the like between solar cell panels.

The present invention has been proposed in view of the above, and is a laying structure in which a continuous beam member is arranged on a surface to be attached having rain performance and a solar cell panel is fixed to a predetermined position of the beam member. In addition, the crosspiece includes a continuous body (main material) disposed between adjacent solar cell panels, and a standard material (secondary material) provided with a flange that supports the back surface at least at a location where the solar cell panel is fixed. The crosspiece member is arranged between adjacent solar cell panels , and has a continuous main body having a tower-like portion at a substantially center, and left and right support surface portions placed on the top of the tower-like portion. In addition, it is combined with a standard material provided with a flange that supports the back surface thereof at least at a place where the solar cell panel is fixed, and the standard material is a step shape in which the support surface portion and the flange have different heights. , solar panels, sun Communicating with the back surface space of the solar cell panel between the side surface or bottom surface of the solar cell panel and the top surface or side wall of the crosspiece member main body at a location where neither the standard material nor the pressing material exists other than the location where the pond panel is fixed. It is related with the laying structure of the solar cell panel characterized by forming and fixing the clearance gap.

Further, the present invention provides the laying structure of the solar cell panel, wherein the laying structure is fixed so as to be sandwiched vertically between a pressing member for pressing the upper surface of the solar cell panel and a fixed member of the crosspiece member. I also propose.

The laying structure of the solar cell panel of the present invention, since the crosspiece member is a continuous material, it can be applied without being restricted by the predetermined fixed location where the solar cell panel is disposed and the size of the solar cell panel, In addition, sufficient fixing strength can be obtained.
And, in the laying structure of the present invention, a gap communicating with the back surface space of the solar cell panel is formed, so even if dust, dust, dirt, etc. enter from the front surface side of the solar cell panel, the gap enters the back space. It can be easily guided and can be smoothly discharged to the lower side by the drainage structure of the surface to be attached.
Therefore, dust, dust, soil, etc., accumulated at the connection portion between the solar cell panels can be kept high in solar power generation efficiency by introducing them together with rainwater to the back space of the solar cell panel.

  In addition, when the crosspiece member is formed by combining a continuous main body and a standard material with a flange, both the main body and the standard material can be made in a simple shape, so that the cost for creating the member can be kept low. Can do.

  In addition, when it is fixed so as to be sandwiched between the pressing member and the crosspiece member that presses the upper surface of the solar cell panel, for example, the pressing member may be attached to the crosspiece member in a fastening form from above. A laying structure with high mounting strength can be obtained.

And although it does not specifically limit as such a crosspiece member, the structure which combined the main body (main material) which is a continuous material, and the fixed scale material (submaterial) provided with a flange is desirable.
In addition, these main bodies and fixed length materials should just be assembled | attached integrally in the laying state, and it does not specifically limit the assembling means. For example, in the illustrated embodiment to be described later, a groove portion that opens upward is formed in the main body, the head portion of the tightening bolt is held in the groove portion, and a regular material or a pressing material provided with a through hole is passed through the tightening bolt. Although a method of integrally assembling by tightening the nut in the state is adopted, it is not particularly limited to this configuration.

  In addition, as shown in the illustrated embodiment to be described later, it is desirable to fix the upper and lower surfaces of the solar cell panel so as to be sandwiched between the pressing member and the cross member. For example, the pressing member is fastened to the cross member from above. A construction to be attached (tightened and attached) is sufficient, and a laying structure with extremely high attachment strength can be obtained.

The solar cell panel laid in the present invention is not particularly limited in its specific configuration. For example, as shown in the illustrated embodiment described later, a solar energy conversion module (hereinafter referred to as a solar cell) is provided on the face plate portion. And a configuration in which a molding portion (frame material) is provided at least on the side edges of the face plate portion, or a solar cell panel may be attached with a cross member interposed.

The solar cell panel in the present invention refers to a panel, a board, a sheet, or the like provided with a module that can be attached (laid) directly or indirectly via a fixing member.
For example, a frame (frame) may be provided around the periphery of the module to form a rectangular shape, or a connection portion between panels may be provided on the frame, and the configuration is not particularly limited. . The solar cell panel may be fixed in a sandwiched manner between the fixing member (pressing member) and the crosspiece member, even if the solar cell panel is fixed directly to the flange of the crosspiece member with a screw or the like. May be. Furthermore, the laying state (attachment state) of the solar cell panel may appear flat or stepwise, and is not particularly limited.

  And in the laying structure of the solar cell panel of the present invention, the dust, dust, soil, etc. adhering to and accumulating on the surface of the solar cell panel are led to the back space of the solar cell panel along with rain water and flow down to the lower side in the flow direction. (Discharge). As a result, since the surface of the solar cell panel is maintained beautifully without adhesion or accumulation of dust or the like that impedes the absorption of sunlight, the power generation efficiency of sunlight can be maintained high.

In the laying structure of the solar cell panel 1 of the first embodiment shown in FIGS. 1A and 1B, a continuous beam member 3 is arranged on the mounting target surface 6A, and the solar cell panel 1 is placed at a predetermined position on the beam member 3. The battery panel 1 can be fixed, and the crosspiece member 3 is formed with a flange 31 that supports the back surface at least at a position where the solar cell panel is fixed. A gap communicating with the back space of the solar cell panel 1 is formed and fixed between the side surface and the bottom surface and the top surface and the side wall of the crosspiece member 3. In addition, although the situation which guide | induces dust, dust, soil, etc. with rain water from the surface side of the solar cell panel 1 was shown by the arrow in Fig.1 (a), it is the flow from the said clearance gap to back space.
Details will be described below.

The said crosspiece member 3 is the structure which combined the main body (main material) 3A which is a continuous material, and the fixed material (submaterial) 3B provided with the flange 31. FIG.
