Description

  The present invention relates to a solar cell panel installation stand, and can be used in particular for solar cell panels of various standard dimensions, and there is no problem in terms of on-site workability and strength, and the installation cost and construction period are suppressed. The present invention relates to a solar cell panel mounting base.

In recent years, solar power generation has attracted attention as a clean power generation method that suppresses the generation of CO ₂ as a global environmental measure, and the installation of a solar power generation system on the roof of a building is being promoted.
Such a solar power generation system is desirably installed in a state where the solar cell panel is inclined at an angle at which sunlight can be efficiently received. For example, as shown in Patent Document 1, the solar cell panel Sp is installed. For mounting, the gantry 1 is configured so that the tilt angle can be adjusted to some extent, and the solar cell panel Sp is installed on the gantry 1 with an inclination of about 30 degrees (see FIG. 11).

  And in order to install a photovoltaic power generation system on the rooftop, a concrete foundation Cf is installed from the building frame, and a frame 1 assembled with a steel frame is placed thereon, and a solar panel Sp is mounted on the frame 1 It was.

  Moreover, as a foundation other than the concrete foundation Cf, there is a metal dry foundation Df for shortening the construction period and reducing the weight, and positioning is performed according to the gantry 1 so that the gantry 1 can be placed with high accuracy, and at predetermined intervals. It has been constructed so as to be planted in a box on the rooftop (see FIG. 12).

However, since the concrete foundation Cf is provided so as to be integrated with the structure of the building, the wind pressure resistance is excellent, but a curing period for hardening the concrete is necessary, and the load capacity of the building structure depends on the weight of the concrete. There was a possibility that it could not be installed.
Moreover, when installing on the rooftop of an existing building, in order to integrate the concrete foundation Cf with the frame, a penetration work for removing the waterproof layer on the rooftop is necessary, and there was a concern of water leakage during the construction period.

  Furthermore, in the dry foundation Df made of metal, since the conventional gantry 1 is installed above the foundation, it is necessary to perform the work by dividing into the foundation installation and the gantry installation as usual (see FIG. 12).

  On the other hand, the solar panel to be mounted on the gantry has different dimensional standards depending on the manufacturer, and the size of the gantry varies depending on the site. In addition, regarding installation, it was necessary to calculate wind pressure resistance at each site.

  Since the gantry 1 mounted on the foundation requires installation accuracy in consideration of power generation efficiency, high accuracy is also required for the installation of the foundation. Therefore, depending on the accuracy of the foundation installation, there is a possibility that the frame cannot be attached.

  1 and 2 show a solar cell panel installation base 10 according to the present invention. The solar battery panel Sp is formed as a panel having predetermined vertical and horizontal dimensions by laying a large number of solar cells Sc vertically and horizontally on one surface, and the outer frame periphery is surrounded by, for example, an aluminum frame edge Pe. ing.

The solar cell panel installation base 10 is for installation on the roof, and a plurality of support bases (here, fixed side support bases 11) for supporting the solar battery panel Sp at an angle (5 to 10 degrees) in advance. And a movable support base 12) (see FIG. 3). The inclination angle is set to 5 to 10 degrees in order to improve the wind pressure resistance. Of course, the inclination angle can be 0 to 60 degrees. The reason why 0 to 60 degrees is conceivable is that it is desirable from the viewpoint of power generation efficiency to be installed in consideration of the daily altitude of the sun that changes from moment to moment, and the changes in the south and middle altitudes of the sun from the winter solstice to the summer solstice.
The fixed-side support base 11 and the movable-side support base 12 are substantially integrated with the fixed base portion 11a and the movable base portion 12a that are grounded on the roof base, and the fixed base portion 11a and the movable base portion 12a, respectively. And supporting column portions 11b and 12b.
Note that the fixed side support base 11 and the movable side support base 12 can be made of a steel material having an appropriate thickness in order to have the necessary strength. And the fixed base part 11a and the support | pillar part 11b, the movable base part 12a, and the support | pillar part 12b can be comprised integrally, for example by welding, or it is also possible to fix with other well-known fixing means.
And the fixed base part 11a and the movable base part 12a protrude over a predetermined range (approximately 100 mm or more from the lower end side of the column parts 11b and 12b) and are grounded on the rooftop. This is because the waterproof layer is affixed to the mount so that water does not flow under the waterproof layer.
By providing the overhang as described above on the fixed base portion 11a and the movable base portion 12a, the waterproof layer is covered with the overhang so that the waterproof layer and the foundation are integrated to eliminate a waterproof water channel (defect). This is because the waterproof performance of the waterproof layer is not impaired. If there is no overhang, the waterproof layer and the foundation cannot be integrated, and a water channel (defect) occurs.

The fixed-side support base 11 is provided with an adjustment receiving portion 13 for receiving the solar cell panel Sp on the upper side of the column portion 11b erected integrally with the fixed base portion 11a according to the panel thickness of the solar cell panel Sp. Provided (see FIG. 4).
The adjustment receiving portion 13 moves and adjusts the receiving edge 13a that receives the solar cell panel Sp to be supported via the frame edge Pe and the vertical direction toward the receiving edge 13a, and the solar cell panel Sp between the receiving edge 13a. And an adjustment frame body 13b that holds the frame edge Pe.
The receiving edge 13a protrudes at a support angle of the solar battery panel Sp (an elevation angle of 5 to 10 degrees with respect to the horizontal plane).
The adjustment frame body 13b includes a well-known fastening and fixing means 14 that restrains the adjustment frame body 13b at an arbitrary adjustment position.
In addition, the fixing base portion 11a of the fixed-side support base 11 is bonded and fixed so as not to move on the base of the roof during construction (adhesive layer B), or appropriate fastening and fixing means F ( Although not shown, for example, bolts are embedded and fixed to the fixing base portion 11a.

On the other hand, the movable-side support base 12 can move the movable base 12a on the ground on the roof according to the size of the solar cell panel Sp to be supported (see FIG. 5).
Further, the column portion 12b in the movable side support base 12 is larger in height than the column portion 11b of the fixed side support base 11 in order to support the solar cell panel Sp at a predetermined angle (5 to 10 degrees). It is said.
Further, an elevating adjustment receiving portion 15 for receiving and supporting the solar cell panel Sp at a predetermined inclination angle (a depression angle of 5 to 10 degrees with respect to the horizontal plane) is provided on the upper portion of the support column portion 12b.
The elevating / lowering receiving part 15 includes an elevating part 15a that is slidably inserted into the column part 12b from the top, and a receiving part 15b that receives and supports the solar cell panel Sp. The receiving portion 15b is set so as to be inclined with a depression angle of 5 to 10 degrees with respect to the horizontal plane when the elevating portion 15a is inserted into the support column portion 12b.
The lifting adjustment receiving portion 15 is provided with a well-known tightening fixing means 16 for fixing the lifting / lowering portion 15a to the column 12b at an arbitrary position when the lifting / lowering portion 15a is inserted into the column 12b. ing. In addition, the receiving part 15b compares the receiving port size with the thickness of the solar battery panel Sp so that it can cope with the difference in the thickness of the solar battery panel Sp to be supported, like the adjustment receiving part 13 of the fixed support base 11. Then, the dimensions may be set to a certain extent, or only the upper part of the receiving portion 15b may be moved up and down to be movable.

Since the solar cell panel Sp installation stand 10 according to the present invention is configured as described above, it can be constructed as described below.
First, on the roof, which is a construction site, the necessary number of solar cell panels Sp corresponding to the area to be installed is prepared, and the fixed side support base 11 and the movable side which are the gantry 10 for supporting each solar cell panel Sp. The support base 12 is carried in.

  An operator arranges the fixed-side support base 11 and the movable-side support base 12 that are the gantry 10 on the roof based on the construction drawing, and performs the work at predetermined positions (see FIG. 6). Of course, in order to grasp the condition of the foundation, it is preferable to investigate and confirm the presence of unevenness, water gradient, etc. in advance and make adjustments.

The fixed-side support base 11 can be fixed to a base such as a waterproof layer on the roof by an adhesive means B or a well-known fastening means F. If the arrangement of the fixed-side support base 11 is determined, the corresponding movable-side support base 12 can be positioned and the solar cell panel Sp can be attached.
That is, while moving the movable base portion 12a of the movable side support base 12 according to the standard size of the solar cell panel Sp to be used, while moving the roof base on the roof according to the size of the solar cell panel Sp to be supported. Then, the fastening fixing means 16 of the lifting adjustment receiving part 15 is loosened, the lifting part 15a is lifted and lowered by the column part 12b, and the opposing frame edges Pe of the solar cell panel Sp are respectively adjusted by the adjustment receiving part 13 of the fixed side support base 11. And is inserted into the receiving portion 15b of the elevation adjustment receiving portion 15 of the movable support base 12. When the solar cell panel Sp does not enter the receiving portion 15b of the elevation adjustment receiving portion 15 of the movable side support base 12, the movable base portion 12a of the movable side support base 12 is moved.
When the thickness of the solar cell panel Sp does not match the adjustment receiving portion 13 of the fixed side support base 11, the tightening fixing means 14 is loosened, the adjustment frame body 13b is raised and lowered, and the tightening fixing means 14 is tightened. The solar cell panel Sp is sandwiched.

As described above, since the solar cell panel Sp can be attached to the gantry 10, unlike the conventional method, it is not necessary to perform the work separately for the foundation installation and the gantry installation, and the on-site workability is greatly improved. To do.
Moreover, in the present invention, since the conventional dry foundation and the gantry are integrated, the number of parts is reduced, and the weight reduction and workability are improved.
In addition, since the installation of the gantry 10 can be performed by moving the movable base 12a of the movable side support base 12 in accordance with the actual size of the panel, it does not require the accuracy for the conventional gantry installation, and the construction is easy. Become.

  In addition, although the installation of the panel is 5 to 10 degrees and the inclination is small and limited, there is no problem in the wind pressure resistance between the fixed side support base and the movable side support base which are the gantry shown in the present embodiment. Furthermore, since the mounting angle of the panel is limited and the number of panels installed per base set is determined, it is easy to calculate wind pressure resistance. Of course, depending on the installation location of the panel, 0 to 30 degrees is possible, which is preferable in terms of power generation efficiency.

As mentioned above, although one embodiment was mentioned and demonstrated about the mount panel for solar cell panels which concerns on this invention, if the support | pillar part and the foundation part are integrated, the structure of a mount will not be restricted to the above-mentioned embodiment.
For example, the embodiment has been described in which the gantry is composed of a pair of fixed-side support base and movable-side support base. However, it is also possible to configure a plurality of three or more fixed-side support bases and movable-side support bases. is there.

In addition, any known mechanism can be applied to the fixed-side support base and the elevation adjustment means.

That is, as shown in FIGS. 7a and 7b, the elevation adjusting means is provided with an adjustment long hole Lh on the support column 11b or the adjustment frame body 13b side of the fixed-side support base 11, and tightening and fixing means 14 is provided. The stud bolt member that can be tightened may be inserted into the support column 11b and the adjustment frame body 13b through the elongated hole Lh, and the adjustment frame body 13b may be restrained at an arbitrary adjustment position.
If the solar cell panel Sp to be used is determined, the fixed-side support base 11 and the movable-side support base 12 are arranged and the fixed-side support base 11 corresponding to the standard dimensions of the solar cell panel Sp. The receiving position of the upper surface of the solar cell panel Sp can be determined in advance. For this purpose, if a hole h is formed and processed at a predetermined height portion of the support column 11b and the adjustment frame 13b at the factory without providing the elevation adjustment means as shown in FIG. It is not necessary to adjust the height (acceptance adjustment) of the adjustment frame body 13b, and the adjustment frame body 13b can be restrained by the fastening and fixing means 14, which leads to a further shortening of the work period.

In addition, as shown in FIG. 8, the adjustment receiving portion 13 clamps the frame edge Pe of the solar cell panel Sp by tightening the fastening fixing means 14 in the vertical direction between the adjustment frame body 13 b and the support column portion 11 b. Is also possible.
