Description

  The present invention relates to a solar module mounting base unit, and more particularly to a solar module mounting base unit that has a simple structure and is easy to assemble on site.

Recently, the expectation for solar power generation as clean energy that does not emit carbon dioxide has been increasing, and along with that, companies that install solar modules on the rooftops of buildings and generate private power are increasing.
By the way, when installing a solar module, it is necessary to maintain a certain angle in order to increase power generation efficiency, and for this purpose, it is indispensable to use a mounting base that supports the solar module in a predetermined inclination state ( Patent Document 1).
JP 2000-101123 A

In the case of the solar cell mounting base device described in Patent Document 1, a mechanism in which a desired inclination angle is realized by attaching a pair of high leg struts and a pair of low leg struts to a mounting frame formed in a rectangular frame shape. It has.

Also in this case, the bolts 30 and the nuts 32 are loosely screwed so that the main material 14 is rotatable.

  As is apparent from the above description, the first transfer member 24 and the second transfer member 26 are integrated through engagement with the main material 14, the rear column material 16, and the front column material 18, respectively.

Hereinafter, the installation and assembly method of the unit 10 will be described with reference to FIGS.
First, as shown in FIG. 1, the unit 10 is placed on a plurality of base members 42 made of a C channel fixed to an installation surface 40 such as a rooftop of a building, and a horizontal surface 24e of the first transfer member 24 is mounted. The horizontal surface 26e of the second transfer member 26 is firmly fixed to the base member 42 via bolts (not shown).

Next, as shown in FIG. 2, the tip of the main material 14 protruding from the front-rear material 12 is lifted with one hand.
As a result, the main material 14 rotates around the bolt 30 to form a predetermined angle with respect to the front-rear material.

Next, as shown in FIG. 3, the rear column member 16 is lifted vertically, and the tip portion thereof is inserted into the main member 14.
That is, as shown in FIG. 9, the distal end portion of the rear column member 16 is drawn to have a narrow lateral width, and can be inserted into the main material 14 (between the side surfaces).
Then, bolts 30 from the outside with respect to the first fixing through holes 14b formed on the left and right side surfaces of the main material 14 and the fixing through holes 16b formed on the left and right side surfaces of the front end portion of the rear column member 16. Is inserted, and the nut 32 is firmly screwed to the tip of the rear column member 16 at the front end.

Next, as shown in FIG. 4, the front pillar member 18 is lifted vertically, and the tip portion thereof is inserted into the main member 14.
Although not shown in the drawing, the front column member 18 is also drawn at the tip portion so as to have a narrow lateral width, so that it can be inserted into the main member 14.
Then, bolts 30 are externally attached to the second fixing through holes 14c formed on the left and right side surfaces of the main material 14 and the fixing through holes formed on the left and right side surfaces of the front end portion of the front column member 18. While being inserted, the nut 32 is firmly screwed to the front end portion of the front column member 18 at the inside.

  Next, as shown in FIG. 5, the first slant member 20 and the second slant member 22 are sequentially lifted and applied to both side surfaces of the main member 14, and the fixing through holes 20c, 22c at the front end are formed on the main member 14 as shown in FIG. After being aligned with the third fixing through-holes 14d formed on both side surfaces, the bolts 30 and nuts 32 are firmly fixed.

  Finally, the bolts 30 and the nuts 32 inserted through the respective rotation through holes are firmly tightened to complete the installation and assembly of one unit 10.

On the base member 42, as shown in FIG. 10, a plurality of units 10 are assembled at regular intervals by the same operation as described above, and the solar module mounting base 50 is constructed.
At this time, in order to increase the strength of the mounting base 50, a reinforcing material made of an angle material may be spanned between the units 10 and fixed with bolts.

  Thereafter, as shown in FIG. 5, a plurality of mounting brackets 52 are screwed to each unit 10, and the solar module 54 is placed and fixed between the mounting brackets 52 of each unit 10. The solar module 54 can also be directly fixed to the main material 14 via bolts and nuts without using the mounting bracket 52.

  In the case of this unit 10, the main material 14, the rear column material 16 and the front column material 18 are rotatably accommodated in the internal space 27 of the front / rear material 12 made of an angle material, and the first diagonal material 20 and Since the second slanting member 22 is rotatably engaged with both side surfaces of the front-rear transfer member 12, the overall shape is compactly formed, and space saving during transportation and storage can be realized.

  When installing, the main material 14 is pulled up at a predetermined angle from the internal space 27 of the front-rear material 12 fixed on the base material 42, and the rear column material 16 and the front column material 18 are pulled up from the internal space 27. Since it is only necessary to fix to the main material 14 with the bolt 30, labor saving is possible.

The present invention is not limited to the above-described embodiment, and various variations are conceivable.
For example, instead of configuring the front and rear transfer member 12 by a combination of a first transfer member 24 and a second transfer member 26 made of an angle member, as shown in FIG. Even if the front / rear material 12 is constituted by an integral steel material having a horizontal surface 24e, a second vertical surface 26a, a second horizontal surface 26e, and a bottom surface α connecting the first horizontal surface 24e and the second horizontal surface 26e. Good.
Alternatively, by using a relatively deep C channel, a front / rear material having a shape that does not have a horizontal surface projecting on both sides may be used.

Also, the number of column members is not limited to two. For example, a central column member that is rotatably engaged with the front / rear material 12 is provided between the rear column member 16 and the front column member. You can also.
Alternatively, instead of attaching the diagonal member to both sides of the front / rear material 12 so as to be rotatable, the diagonal member made of a C channel is rotatably stored in the internal space 27 of the front / rear material 12 like the column material. You may keep it.
