DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for fixing a solar heat collector via a supporting tile and a solar heat collector using the fixing structure.

[0002]

2. Description of the Related Art A solar heat collector is a device that is installed on a roof or a roof, and collects solar heat energy and stores it as hot water. From the viewpoint of workability, heat collecting property, manufacturing aspect, etc., about 2 to 6 solar heat collectors are often combined and installed. Various construction methods are known.

One of them is installation of a solar heat collector by wire fixing (FIG. 7). First, the two cross rails 4 are placed so as to be parallel to the ridge 5, and are temporarily fixed to the keraba 7 and the eaves 8 using a plurality of radially extending wires 6. The solar heat collectors 1 are placed one by one on the temporarily fixed horizontal rail 4 so as to be parallel to the keraba 7 from the ridge 5 to the eaves 8 and fixed by connecting bolts. At this time, the temporarily fixed horizontal rail 4
Repeat the work of loosening and fixing each wire 6 so that the through hole of the horizontal rail and the through hole of the fixed angle attached to the solar heat collector 1 can communicate with the connecting bolt, and securely tighten the connecting bolt. Adjust to a position where you can. Thereafter, in order to improve the appearance of the solar heat collector 1 on the roof 2, the ridge 5 and the two sides of the solar heat collector 1 are parallel to each other, and the vertical line of the roof tile 3 and the solar heat collector Each wire 6 is adjusted so that one other two sides are parallel.

FIG. 8 shows another conventional construction example, that is, a construction example of a solar heat collector using a supporting tile. In advance, a roof tile at a predetermined position in the entire roof is replaced with a support tile. First, a support tile adapter is attached to the support portion of the support tile.
The cross rail 4 is fixed using the through hole of the cross rail 4 and the hole of the supporting tile adapter. After that, the solar heat collector 1 is fixed using the fixing angles and the connection bolts.

In recent years, together with the solar heat collector, a solar cell module having a plurality of rectangular or square light receiving surfaces is often provided on a roof or a rooftop.

[0006]

However, in the above-mentioned wire fixing method, the appearance is impaired by the wires radiating around the solar heat collector. In addition, installation and position adjustment of the solar heat collector are repeated by wire fixing and temporary fixing,
It takes time and effort. Further, in the fixing method using the supporting tile,
Mounting members must be prepared for each type of roof tile (different dimensions). The prepared mounting member may not be able to be attached depending on the variation in the dimensions of the supporting tile or the mounting tolerance.
When a solar cell module and a solar heat collector are installed side by side, position adjustment between the solar heat collector and the solar cell module is also troublesome.

SUMMARY OF THE INVENTION An object of the present invention is to solve these problems, that is, it does not impair the aesthetic appearance, does not require any trouble, and can be mounted even if there is some variation in the dimensions of the supporting tile and mounting tolerances. An object of the present invention is to provide a fixing structure of a solar heat collector, which can easily adjust a distance between the battery module and the battery module.

[0008]

In order to solve the above problems, the present invention has the following configuration. That is, the fixing structure of the solar heat collector according to the present invention is a fixing structure of the solar heat collector 1 which is fixed via the support tile 17 in which the support portion 25 having a hole and standing upright is integrated. In the support portion 25, a plurality of (normally two) horizontal rails 4 having a plurality of horizontal adjustment holes 21 and a ridge 5 (or eave 8) are provided.
The horizontal rail 4 is fixed in parallel with the horizontal rail 4 through a fixing angle 13 in which the vertical adjustment holes 22 are arranged in the vertical direction (that is, the direction perpendicular to the ridge 5 or the direction along the keraba 7). This is a solar heat collector fixing structure for fixing the solar heat collector 1 while appropriately selecting the adjustment hole 21 and the vertical direction adjustment hole 22.

Here, if the horizontal adjustment hole 21 of the horizontal rail 4 and the vertical adjustment hole 22 of the fixed angle 13 are appropriately selected,
It is possible to freely adjust from the hole pitch of the horizontal adjustment hole to the horizontal pitch (WP) of the roof tile, and from the hole pitch of the vertical adjustment hole to the vertical pitch (HP) of the roof tile.

[0010] The supporting tile is a tile having a support portion in which two-shaped or clogged tooth-shaped protrusions protrude upward. The support portion has a hole, and is integrally formed with the tile body. It is a roof tile that has been formed. Usually, it is made of metal.

The fixing of the supporting tile 17 and the horizontal rail 4, the fixing of the horizontal rail 4 and the fixed angle 13, or the fixing of the fixed angle 13 and the solar heat collector 1 are performed by holes formed in each member. Fasteners (e.g., connecting bolts, screws, bolts / nuts) that penetrate through the portion are preferably used.

In the above-described fixing structure, a horizontal rail 4 having a plurality of holes can be used in place of the horizontal rail 4 having a horizontal adjustment hole.

The fixing of the supporting tile 17 to the horizontal rail 26 and the fixing of the fixing angle 13 to the solar heat collector 1 include fixing with fasteners which penetrate through holes formed in each member and fasten. The horizontal rail 26 and the fixed angle 13 are preferably fixed using a T-shaped flanged bolt 27 fitted into the horizontal rail, for example. When the horizontal rail 17 is used, the position in the horizontal direction can be finely adjusted using the mobility of the bolt with a T-shaped flange fitted into the horizontal rail.

The present invention also relates to a solar heat collector using the above-mentioned fixing structure.
