DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting bracket used for mounting solar energy utilizing equipment such as a photovoltaic power generation facility on a roof of a corrugated slate, and a mounting base using the mounting bracket.

[0002]

2. Description of the Related Art When a photovoltaic power generation system is installed on a large wave slate used for a roof of a building such as a factory, a frame is conventionally directly attached to a fixing bolt of the slate. In this case, the fixing bolt of the slate has a configuration in which the hook at the lower end is engaged with the roof structural material, and the upper end is inserted into the top of the slate wave and fastened with a nut. Is merely engaged with the roof structural member, so that fixing the gantry to the bolt end protruding above the roof does not provide sufficient supporting force.
For this reason, conventionally, the base has been attached after welding the hook portion of the fixing bolt to the roof structural material.

[0003]

Conventionally, since the gantry is directly mounted on the fixing bolt of the slate, a large-scale remodeling work for welding the fixing bolt to the roof structural member prior to mounting the gantry as described above has been performed. Therefore, there is a problem that the construction period is lengthened and the construction cost is increased.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a mounting bracket for realizing a mounting structure for a gantry that does not require a large-scale remodeling work as described above, and a mounting gantry using the mounting hardware.

[0005]

According to the present invention, a mounting bracket for achieving the above object comprises a horizontal frame arranged on a top surface of a waveform slate in a direction perpendicular to a direction of a wave of the slate, and a screw of a fixing bolt of the waveform slate. In the mounting bracket for solar energy utilization equipment used for connecting to the mounting portion, a downward leg is provided on both sides of the substrate portion of the mounting bracket, and a fitting recess of the screw portion of the fixing bolt is formed between both legs. A screw hole for screwing with the screw portion is provided on a lower surface of the substrate portion on which the fitting recess is formed, and mounting holes for the horizontal frame are provided on both sides of the screw hole in the direction of the slate wave; Are formed by vertically long holes.

Further, in the mounting base using the mounting bracket, a required number of mounting brackets according to claim 1 are provided on a top of a corrugated slate constituting a roof of a building in a direction perpendicular to a direction of a wave of the slate. The screw holes of the mounting bracket are screwed into the threaded portions of the fixing bolts protruding from the upper surface of the slate, and the horizontal frame arranged at the top of the slate in a direction perpendicular to the direction of the wave is aligned with the mounting bracket. The horizontal frame is fixed by bolts passing through the mounting holes of the mounting bracket, and the vertical frame is combined with the horizontal frame.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a photovoltaic power generation facility in which a solar cell module 3 is mounted on a large wave slate 1 constituting a roof of a building via a mounting base 2. Large wave slate 1 above
A wooden blanket 5 is interposed on a C-shaped steel 4 as a roof structural material provided in a required number in parallel with the roof purlin, and the wave top 6 or valley 7 moves up and down between the eaves and the ridge. In the direction extending in the direction (hereinafter, referred to as the direction of the slate wave),
A hook 9 (see FIG. 2) of the fixing bolt 8 is engaged with the C-shaped steel 4, and a nut 11 is inserted through a rubber packing 12 and a washer 13 into a screw portion 11 at the upper end of the fixing bolt 8 protruding onto the slate 1. 14 are fastened and fixed.

A mounting bracket 15 is fixed to the screw portion 11 of the fixing bolt 8. As shown in FIG. 4, the mounting bracket 15 has a downward U-shape with legs 17, 17 provided on both sides of the substrate 16, and the screw 11, nut 14, and the like between the legs 17. A fitting recess 18 is formed. A screw hole 19 opened in the fitting recess 18 is provided on the lower surface of the substrate portion 16 of the mounting bracket 15, and the screw portion 11 of the fixing bolt 8 is screwed into the screw hole 19.

In addition, the substrate 16 above the both legs 17
In the direction perpendicular to the screw hole 19, two mounting holes 21 are provided in the direction of the slate wave so as to penetrate the substrate portion 16. Each of these mounting holes 21 is a long hole having a long diameter in the vertical direction.

As shown in FIG. 1, the mounting brackets 15 are arranged at required intervals in a direction perpendicular to the direction of the slate wave, and are mounted on the fixing bolts 8. Attachment is performed by screwing the screw hole 19 of the mounting bracket 15 into the screw portion 11 protruding from the upper surface of the slate 1 of the fixing bolt 8, and the two leg portions 1.
3 is screwed while rotating the mounting bracket 15 until the lower end of the top 7 is aligned with the height of the top 6, so that both legs 17 straddle the top 6 and face the valleys 7 on both sides as shown in FIG. . The screw portion 11, the nut 14, and the like are fitted into the fitting concave portions 18.

When the above-mentioned mounting work is performed, the screw portion 11 of the fixing bolt 8 may be rusted on the existing roof or the like.
If the amount of protrusion is insufficient, the fixing bolt 8 is replaced.

After fixing the required number of the mounting brackets 15 in the direction perpendicular to the direction of the slate wave and the required number of stages in the direction of the slate wave, the channel-shaped horizontal frame 22 of the mounting base 2 is moved in the direction of the slate wave. Are arranged on the top 6 at right angles to the top and along the front side (eave side) of the mounting bracket 15 (see FIGS. 1 and 2. In FIG. 1, the upper side of the drawing is the eave side and the near side is the ridge side. It becomes.).

The above-mentioned horizontal frame 22 is attached to the mounting bracket 15.
Pass the mounting bolt 23 through the mounting hole 21 of the
Is fixed by fastening.

The height of the top 6 and the irregularity of the mounting portion are adjusted within the range of the long diameter of the mounting hole 21.

A required number of hat-shaped vertical frames 25 are arranged on the horizontal frame 22 at predetermined intervals in the direction of the slate wave.
And fixed.

The solar cell module 3 is arranged on the mounting base 2 configured as described above. As shown in FIG. 3, the solar cell module 3 is attached by engaging a downwardly U-shaped holding metal fitting 28 attached to the vertical frame 25 with a bolt / nut 27 with a flange edge 29.

The photovoltaic power generation equipment according to the embodiment is as described above. The weight of the mounting base 2 composed of a combination of the horizontal frame 22 and the vertical frame 25 and the solar cell module 3 mounted thereon and acts on them. The downward load due to the wind pressure is dispersed and supported at the contact portion between the horizontal frame 22 and the top portion 6 of the large wave slate 1 and does not excessively act on the engaging portion of the fixing bolt 8 with the hook 9.

A load that causes the facility to slip down along the roof slope and an upward load that is lifted by wind pressure are applied to the fixing bolt 8, but exert a sufficiently large resistance to these loads.

[0020]

As described above, the mounting bracket according to the present invention has a function of connecting the gantry to the fixing bolt and blocks transmission of a downward load acting on the gantry to the fixing bolt. For this reason, the fixing bolt only needs to engage the hook at the lower end with the roof structural material as before, and therefore, when installing a mount using this mounting bracket, the roof remodeling work is substantially unnecessary, and The time can be reduced and the cost can be reduced. Also,
Since the load acting on the gantry is dispersed and supported by the top of the corrugated slate via the horizontal frame, it is possible to avoid concentration of the load on a part of the corrugated slate.
