Description

  The present invention relates to an installation base structure of a photovoltaic power generation module for fixedly installing a plurality of photovoltaic power generation modules at a predetermined installation location.

  In recent years, photovoltaic power generation using sunlight, which is a renewable energy resource, has attracted attention, and in addition to vacant land, solar power generation modules are installed on the roof of a house or the roof of a building. In the case of a general house, since the roof has an inclination in the first place, it is common to install a required number of photovoltaic power generation modules including a plurality of solar cells in a direction in which sunlight is easily received along the inclination of the roof.

  On the other hand, when installing a panel-like photovoltaic power generation module on a flat installation location such as a so-called flat roof on the ground surface or the rooftop of a building, it is necessary to hold the photovoltaic power generation module at a fixed inclination angle. An installation stand is used. In Japan, in order to achieve the most efficient power generation, it is desirable to keep the solar power generation module at an inclination angle of about 30 ° from the horizontal installation surface in consideration of sunlight and snow melting effect. Yes.

  Therefore, for example, as described in Patent Document 1, three bases made of FRP are arranged in a row and these are set as one set, and the other set is arranged in parallel at a predetermined interval. A long H-shaped base member made of FRP is bridged between adjacent bases, and the two base members are connected in the length direction and fixed on the base of the set. A plurality of pillar members are erected on the base member on the base at regular intervals, and a plurality of inclined support members are bridged between each pillar member and the base member on the other pair of bases, and each is reinforced with a reinforcing member. Thus, it has been proposed to form an installation base for the photovoltaic power generation module, and to install the solar power generation module on each inclined support member of such an installation base.

  However, the solar power generation module is not limited to the ground surface, and may be installed on the rooftop of the building. In the case of the installation stand having the configuration described in Patent Document 1, the FRP base is installed on the ground surface or the building rooftop. However, it is possible to withstand strong wind loads and earthquake vibrations simply by installing the base because it cannot withstand strong loads or earthquake vibrations and stably support the photovoltaic module. In order to do so, it is necessary to prepare special fixing means for fixing each base to the ground or the roof of the building, and it is necessary to improve the base to attach the fixing means to the base. There is a problem that it causes an increase in costs and an increase in assembly man-hours.

  The present invention has been made in view of the above problems, and an object thereof is to provide an installation base structure for a photovoltaic power generation module that is inexpensive and easy to handle and can be firmly fixed to the ground surface or a building roof.

Show.

  The installation base structure of the photovoltaic power generation module according to the present invention is a type to be installed on the ground surface. As shown in FIGS. 1 to 3, a plurality of concrete blocks 1 having a convex shape in a side view are prepared in advance and are predetermined. These concrete blocks 1 are carried on the ground surface G in the form of a matrix of 2 rows and N columns (N is a natural number), for example, and the foundation block portion 2 is formed at the lower four corners of each concrete block 1 As shown in FIG. 4, the anchor 4 is inserted into the through-hole 1 a pierced and driven into the ground, and each concrete block 1 is fixed.

  One long column member 6 having a square cross section is erected on each concrete block 1 in one row of the foundation block portion 2 and two are erected on the concrete block 1 in every third row. As with the long column member 6, one short column member 7 having a square cross section is erected on each concrete block 1 in the other row of the foundation block portion 2 and on the concrete block 1 in every third row. There are two standing up.

  Further, for each row, a beam member 9 having a square section longer than the interval between the two concrete blocks 1 in each row is bridged between the upper end of the long column member 6 and the upper end of the short column member 7. The beam members 9 for each column, which are fixed to the column members 6 and 7 by bolts or the like and arranged in the direction orthogonal to the row direction, are arranged at a predetermined angle (for example, 30 degrees) from the ground surface. A plurality of cross members 10 having a circular cross section parallel to the row direction are arranged on the members 9 and fixed to the beam members 9 with bolts or the like, and a plurality of panel-like photovoltaic power generation modules Mj are arranged on each cross member 10. Laid in state.

  By the way, the anchor 4 for fixing the concrete block 1 to the ground is configured as shown in FIGS. 7 (a) and 7 (b), for example. That is, it has an anchor body 4a, two E-rings 4b and 4c attached near the lower end of the anchor body 4a, and a pull-out preventing metal fitting 4d. Among these, the anchor body 4a is formed by processing a round bar-shaped steel material extending in the vertical direction X, and has a tip 4e that is driven into the ground in advance at the lower end thereof, and the concrete block 1 at the upper end. The anchor 4 has a columnar portion 4f larger in diameter than the anchor main body 4a that can be inserted into the through hole 1a. The anchor 4 is driven into the ground by hitting the head of the columnar portion 4f with a hammer.

The pull-out preventing metal fitting 4d is formed by bending the blade portion of the substantially cross-shaped spring steel plate upward at the portion where the base portion 4d1 and each blade member 4d2 are connected.

  In such a pull-out prevention metal fitting 4d, a collection space CS surrounded by the base 4d1 and the four blade members 4d2 is formed on the opposite side (upper side in FIG. 1) of the anchor body 4a to the base 4d1. When the anchor 4 is driven into the ground, the soil in the ground flowing into the collection space CS from the gap 4d3 between the adjacent blade members 4d2 can be collected by the pull-out prevention metal fitting 4d, and the repaired soil can be collected by the anchor 4 It is used as a resistance when pulling out, and the anchor 4 is prevented from easily coming off from the ground even if a shake due to an earthquake occurs, so that the installation state of the concrete block 1 on the ground surface G is stably maintained. . Since the blade member 4d2 is made of a spring steel plate as described above, the blade member 4d2 has a spring property, and can be driven with a minimum resistance when the anchor 4 is driven.

  Therefore, according to the first embodiment described above, the beam member 9 spanned between the upper ends of the plurality of long column members 6 and the upper ends of the plurality of short column members 7 while being inclined at a predetermined angle from the ground surface G. Since a plurality of crosspiece members 10 are arranged orthogonally on top and a plurality of panel-like photovoltaic power generation modules Mj are laid on each crosspiece member 10, anchor 4 is driven into the ground to fix each concrete block 1 As a result, the entire gantry can be stably fixed to the ground surface G, and it does not require any special fixing means as in the past, is inexpensive and easy to handle, and is firmly installed on the ground. Can be fixed.
