DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof-mounted device, and more particularly to a roof-mounted device having a solar cell module, a solar water heater, and the like installed on a roof.

[0002]

2. Description of the Related Art FIG. 4 is a perspective view for explaining a conventional roof-mounted device.

[0003] A conventional roof-mounted device includes a device including a solar cell module and a solar water heater, a gantry 1 on which the device is mounted, and a cushioning material 3 disposed between the gantry 1 and the roof tile 2. It is a configuration consisting of In the figure, reference numeral 4 denotes a solar cell module, which is shown in the figure as an example of a device.

Conventionally, when a device such as a solar cell module or a solar water heater is arranged on a roof tile 2 such as a Japanese tile of a tiled roof via a gantry 1, it is most suitable to sandwich the device between the gantry 1 and the roof tile 2. Since there was no cushioning material also serving as a cushion, a thick neoprene rubber sheet or several neoprene rubber sheets having different thicknesses were used as the cushioning material 3 and cut to the required size on site. The cushioning material 3 is arranged not on the concave portion of the surface of the roof tile 2 but on the convex portion from the viewpoint of drainage.

The surface of the roof tile 2 such as a Japanese tile has large irregularities and the flatness of the roof surface itself having the same gradient may not be sufficient. Several types of neoprene rubber sheets having different thicknesses are sandwiched between the cushioning materials cut out from a neoprene rubber sheet having a thickness of about 20 mm or in a tapered gap with the roof tile 2 when the gantry 1 is placed on the roof tile 2. The cut cushioning material was inserted into the gap.

The gantry 2 is made of steel.
It had a concave base with one surface opened, and had two upper and lower stages, and was formed to be as long as required.

[0007]

However, the above-mentioned roof-mounted apparatus has the following problems.

Since the neoprene rubber sheet used as the cushioning material 3 has a smooth surface and low frictional resistance, when the base 1 made of channel steel or lightweight C-lip channel steel is placed on the cushioning material 3, There is a case where the gantry 1 slides on the cushioning material 3, which makes the work difficult and dangerous. Further, the cushioning material 3 is naturally not adapted to the wavy curved surface of the Japanese roof tile or the like and easily slides down from the convex portion of the Japanese roof tile, so that the workability is poor when the gantry 1 is put on the cushioning material 3. This workability becomes worse as the roof inclination angle increases, and the danger increases.

As a countermeasure for this, a cushion 3
It is conceivable to bond the roof tiles with an adhesive or the like. However, there are dozens of types of roof tiles 2 having different sizes and corrugated pitches. ， Difficult in terms of delivery.

Further, the cushioning material 3 is only partially subjected to the weight of the equipment and the gantry 1 and is therefore extremely compressed and deformed. In the worst case, there was a problem that a crack ran in No. 3 and stopped functioning.

Further, the cushioning material 3 does not properly disperse the load on the roof tile 2 and is one of the factors such as cracking of the roof tile and leak of rain.

The neoprene rubber sheet is inexpensive and has relatively good weather resistance, but carbon or the like is used to obtain weather resistance characteristics, and the insulation resistance characteristics are not good.
If a part of the DC high-voltage current leaked from the solar cell module to the base 1 flows to this neoprene rubber sheet, it is obligatory to ground the base, but a tile without a vitreous topcoat is required. In the case of (1), there is a concern that the surface of the tile is scorched and the tile is charged by carbon (carbon) contained during baking.

Also, when the solar cell system of the mount 1 is a solar cell mount of about 3 kW, the mount becomes considerably large in both dimensions and mass, and is stored, transported, carried on a general home roof, etc. Needed cranes.

Due to such problems, it has not been considered that an object is placed on a roof in a conventional general house, and a tiled roof, particularly a Japanese tile, such as a solar water heater or a solar cell module, is not considered. It was a very difficult task to put the equipment.

An object of the present invention is to solve the above problems.

[0016]

According to the present invention, there is provided a roof-mounted device comprising: a device to be placed on a roof tile; a gantry for mounting and fixing the device; and a cushioning material to be placed between the gantry and the roof tile. In the roof-mounted device, the cushioning material has a portion in contact with the roof tile corresponding to the surface shape of the roof tile, and a non-slip groove on the surface with respect to the inclination direction of the roof. The thickness of the cushioning material is gradually increased from the upper stage side to the lower stage side of the roof.

For example, a female screw is provided in the connecting body 17, a through hole is provided in the pipe portions 14 a, 15 a, and a male screw is fixed to the female screw through the through hole from the surface of the pipe portion.

A plurality of non-slip V-grooves (not shown) are provided on the surfaces of the quadrangular prism pipes 14 and 15 in contact with the cushioning material 13 in the direction in which the pipes extend. The non-slip groove can be easily formed in the V groove by, for example, providing a triangular projection with a pitch of about 1 mm in an extrusion die and extruding the groove.

The device, for example, a solar cell module,
The square pillar pipes 14 and 15 are attached to the gantry 11 in which two rows are arranged by screws or the like. For example, it is fixed to a female screw provided on the gantry 11 using a male screw (hexagon bolt or the like).

The gantry 11 is fixed to the roof with metal fittings or wires protruding from the gap between the tiles.

The cushioning material 13 provided between the gantry 11 and the roof tile 12 such as a Japanese tile has a high insulation resistance and a high weather resistance.
As shown in FIG. 2, the cushioning material 13 is formed by tapering one surface in accordance with the convex curved surface of the roof tile 12, as shown in FIG. 2. FIG.
(A) is a plan view, (b) is a plan view, (c) is a bottom view, (d) is a side cross-sectional view, and (e) is an enlarged view of a portion A in (a). FIG.

Non-slip grooves 18 and 19 are formed on the contact surface of the cushioning material 13 with the roof tile 12 and the contact surface with the gantry 11.
