Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting bracket for a pedestal installed on a roof for supporting devices such as solar cells on the roof.

[0002]

2. Description of the Related Art Conventionally, when a solar cell for photovoltaic power generation is installed on a roof of a house, a mount is first installed on the roof, and then a solar cell module is fixed to the mount. .

As a fixing means for such a mount, a screw inserted into the mount is screwed into the base plate from above or nailed (for example, Japanese Patent Publication No. 4-23).
702, etc.).

Alternatively, in a solar heat collector installed, the mount of the heat collector may be fixed by a bolt to a metal fitting fixed to the lower purlin of the base plate.
That is, the tip of the bolt attached to the metal fitting penetrates the field plate and roofing material at the upper part of the main house to project upward, and the pedestal is clamped and fixed at this projecting portion (Actual Publication 61-
42042).

[0005]

In the above, in the case of nailing or screwing from the upper surface side of the roof, the nails or the screws may come off when a strong upward pulling force is applied due to strong wind, etc. There is a problem of lack of reliability. On the other hand, in the case of fixing to the base plate via bolts and metal fittings, the metal fittings are attached to the purlin in advance,
The base plate is installed while aligning the bolts attached to the metal fittings with the bolt holes of the base plate.If there is an error in the position of the bolt or the bolt hole, increase the hole diameter of this bolt hole. However, since the bolt must be inserted, workability is poor, and when the hole diameter is increased, a large gap is formed around the bolt, which is not preferable in terms of waterproofing.

The present invention solves the above-mentioned drawbacks of the prior art, and fixes a mount for mounting a solar cell or the like to a roof base crosspiece such as a purlin via a support metal fitting and bolts. The purpose of the present invention is to provide a supporting metal fitting having good attachment properties and high mounting strength.

[0007]

[MEANS FOR SOLVING THE PROBLEMS] In order to solve the above-mentioned pedestal, the metal fitting of the present invention comprises a fixing member fixed to a roof base crosspiece of a purlin or the like, and an outer side surface of a vertical piece of the fixing member.
