Description

  The present invention relates to a support base structure for a solar cell panel, and more particularly to a support base structure for a solar cell panel that is independently supported for small to large solar cell panels.

  There is no environmental pollution due to emissions, no fuel consumption such as petroleum resources, and solar cells that convert inexhaustible sunlight directly into electricity are ideal power sources and energy if they can improve energy conversion efficiency. In the present situation where research and development for improving the conversion efficiency are constantly being carried out, it is one of the options as an attractive power energy generation source. In particular, expectations for solar power generation are increasingly high in the event of an accident that sounds a warning about the dependence on nuclear energy associated with the previous Tohoku earthquake.

  Photovoltaic power generation generates electricity directly by the photon effect caused by light colliding with semiconductor atoms when light is incident on a semiconductor such as silicon. A solar cell module is formed by assembling semiconductor cells. In addition, the solar cell panel panel surface in which a plurality of solar cell modules are formed into a thin flat plate is arranged at an inclination angle with good irradiation efficiency, and directly generates sunlight to obtain power generation energy. . Conventionally, for example, Patent Document 1 proposes a method in which unit solar cell panels are assembled in a large area in order to obtain large power energy by solar power generation.

JP 2011-911166 A

  The photovoltaic power generation array mount of Patent Document 1 is provided with an airflow control plate that forms a ventilation slit between a lower surface of a solar cell panel on an inclined upper column supporting a solar cell panel that is installed at an inclination, and the ventilation slit The downforce generated in the airflow control plate by the wind passing through is transmitted to the support column, and thereby, it is intended to reduce the lift generated in the solar cell panel by the lower component of the wind passing through the slit. To do. However, the photovoltaic power generation array frame of Patent Document 1 has four foundation blocks installed at positions corresponding to the four corners of a rectangular solar cell panel, and two upper and lower foundation blocks are respectively connected to the upper part thereof. Requires horizontal mounting bases, columns 2A, 2B, beam 6 and so on, positioning of the four foundation blocks, setting of the upper height of the foundation block corresponding to the unevenness on the ground side, fixing of the shape steel, etc. There are many fine setting operations such as fixing to the diagonal members 3 and 4 for angle adjustment of the control plate 11, and it takes time for the whole construction work. On the contrary, there is a disadvantage that the material cost becomes high, and at the same time, the construction cost is greatly increased. In addition, since the foundation blocks are not joined together, an external force at that time is directly applied to the solar panel when the ground side is shaken such as an earthquake, and the solar power generation system may be surely destroyed.

  The present invention has been made in view of the above-described conventional problems, and one object of the present invention is that it can be easily installed on site in a short time with a simple structure, and maintains high strength while being low in cost. An object of the present invention is to provide a support base structure for a solar cell panel that can prevent the panel from being damaged early and directly.

  In order to solve the above problems, the present invention includes a solar cell panel 2 that is inclined at a required gradient at a required ground height, and a plurality of concrete products that are installed on the ground and receive the solar cell panel from the lower side. Each of which is formed with different heights at the upper ends, includes a bottom plate portion 6 and height support portions 10 and 11, and is arranged so as to face each other so as to receive the solar cell panel 2 with a predetermined gradient. A plurality of support bases 501A and 501B, at least one insertion rebar 22 inserted and arranged in common in the bottom plate portion 6 of all support bases, a straight rebar 22 having an arbitrary length, and a cast-in-place concrete part 24, and an in-situ bottom bottom plate integration mechanism 3 for integrally connecting the bottom plate portions 6 to each other through a support panel structure 1 for a solar cell panel.

  At that time, some or all of the bottom plate portions 6 of the respective support frames include a hollow portion 7 having a hollow portion 7a punched in the vertical direction, and a bottom plate frame 8 in which the hollow portion 7 is formed inside, It is preferable to have a reinforcing bar insertion hole 12 that penetrates the bottom plate frame in the lateral direction.

  The reinforcing bar insertion hole 12 is preferably a hole having a diameter size at least twice that of one reinforcing bar to be inserted.

  Furthermore, the reinforcing bar insertion hole 12 may be an hourglass-shaped hole that gradually becomes smaller in diameter toward the center from the opening portions at both ends.

  Moreover, it is preferable that some or all of the plurality of support platforms have the same outer size of the bottom plate portion 6 and have different height support portions.

  According to the support structure of the solar cell panel of the present invention, a solar cell panel that is inclined at a required gradient at a required ground height, and a plurality of solar cell panels that are installed on the ground and receive the solar cell panel from the lower side. A concrete support pedestal, each having a different top end height, including a bottom slab portion and a height support portion, spaced apart from each other so as to receive the solar cell panel with a predetermined gradient. Each of the bottom slab parts via the support frame, at least one insertion reinforcing bar that is inserted and arranged in common to the bottom slab parts of all the support cradles, and a straight reinforcing bar having an arbitrary length, and a cast-in-place concrete part Since the structure is equipped with an in-situ bottom plate integration mechanism that connects the concrete together, the support platform as a concrete secondary product manufactured in advance in the factory is transported to the installation site, and the designed position It is only necessary to place the concrete in the state of being placed facing each other and the inserted reinforcing bars inserted into all the support bases. (A) With a simple structure, (b) Easy and (c) Complete on-site installation in a short time The main components are made of concrete secondary products, and (d) low-cost (e) relatively small concrete secondary products can be transported on-site easily. It is possible to constitute a support base for the battery panel. In particular, the high and low support heights can be positioned easily and in a short time by the support frame. Furthermore, by integrating the bottom plate at the site and making the entire support frame unit rigidly joined, it becomes difficult for external forces to be applied directly to the solar cell panel when the ground side is shaken such as an earthquake. The strength of the solar power generation system can be enhanced, the durability of the photovoltaic power generation system can be improved, and further, the construction efficiency can be improved, the cost can be reduced, and the construction time can be shortened.

  In addition, some or all of the bottom plate portions of the respective support bases have a hollow portion having a hollow hole punched in the vertical direction, a bottom plate frame having a hollow portion formed inside, and a horizontal penetration through the bottom plate frame. Reinforcing rod insertion holes to be configured, so that the bottom plate is made of reinforced concrete and the entire structure is rigidly bonded, maintaining the high strength of the entire structure, and changing the insertion reinforcing bar length or adjusting the insertion length Thus, it is possible to finely adjust the width of the interval between the support frames at the installation site.

  Also, the reinforcing bar insertion hole is at least twice as large as the diameter of a single reinforcing bar to be inserted, so that the concrete placed on the site is the side of the space between the bottom plate part and the support frame Easily enters the reinforcing bar insertion hole and is filled with a good density, and the connection strength of the bottom plate portion can be maintained.

  Further, the reinforcing bar insertion hole is an hourglass-shaped hole that gradually becomes smaller in diameter toward the center from the opening portions at both ends, and therefore has sufficient resistance holding force in the pulling direction even when stress is applied from the outside.

  In addition, some or all of the plurality of support platforms have the same outer size of the bottom plate part, and the height support part has a different height so that the bottom plate part is common and only the height is different. It is only necessary to manufacture the support frame, and the design and production cost of the same mold can be reduced.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a support base structure for a solar cell panel according to the present invention will be described with reference to the accompanying drawings. The solar cell panel support frame structure of the present embodiment is a solar cell panel support frame structure in which a plurality of semiconductor cells are assembled to form a solar cell module, and the plurality of solar cell modules are panelized into a thin flat plate shape. In particular, the present invention can be widely applied to a structure in which a plurality of solar cell panels are interconnected and arranged in parallel to form a large panel by tilting and supporting the entire solar cell panel by independently installing and supporting a small solar cell panel.

  1 to 4 show a support base structure for a solar cell panel according to a first embodiment of the present invention. In the figure, a support base structure 1 for a solar cell panel is, for example, a support base unit group arranged in parallel in the vertical and horizontal directions. It is applied to a solar panel power generation system in which 5G is formed and a large light receiving area is formed as a whole.

  The solar cell panel support frame structure 1 of the first embodiment shown in FIG. 2 is integrated with a solar cell panel 2, a plurality of support frames 501A, 501B, and a plurality of support frames at the bottom plate part. Mechanism 3. In FIG. 2, one support frame structure 1 includes a plurality of support frames 501A and 501B. In the embodiment, the support bases 501A and 501B constitute the support base unit 5U. One support frame structure 1 includes one support frame unit 5U, and the support frame unit 5U includes two or more support frames. In this embodiment, the support frame unit 5U includes two support frames 501A and 501B, and these support frames 501A and 501B are arranged to face each other with a gap S therebetween.

  The support bases 501A and 501B are base means made of a concrete secondary product that is installed on the ground and receives the solar cell panel 2 from the lower side. The upper ends of the support bases 501A and 501B have different upper and lower heights. The solar cell panel 2 is supported in an inclined state at a required gradient at a required ground height. In FIG. 2, the height h1 of the support frame 501A is set higher than the height h2 of the support frame 501B. In this embodiment, the support frame 501A is the upper frame and the support frame 501B is the lower frame. The support bases 501A and 501B are formed such that the bottom plate portion has the same outer shape and outline shape, and only the top end height is different.

  Referring to FIG. 4, a description will be given of one upper support frame among the support frames, for example, the support frame 501A. The support frame 501A is integrated with a plurality of pillars standing on a flat rectangular frame in a schematic view. It is a concrete structure with a shaped shape. Specifically, it includes a thick plate-long rectangular bottom plate portion 6 having an outer contour and a height support portion 10 integrally connected in an inverted T-shape from the bottom plate portion 6. A hollow portion 7 having a hollow hole 7a punched into a rectangle is formed. The height support portion 10 is configured by raising three support columns 101 in an inverted T shape at three locations, the longitudinal end portions and the center portion of the bottom plate portion 6. The bottom plate portion 6 is formed in a long rectangular frame shape having two hollow holes 7a provided inside separated by an intermediate column 101b, and as shown in FIG. Six reinforcing bar insertion holes 12 are formed in the shape of the longitudinal frame 8 so as to penetrate in the lateral direction, three by three corresponding to each hollow hole 7a.

  Each column 101 includes a trapezoidal portion 14 whose lower portion is joined to the bottom plate portion 6, and further rises upward from the trapezoidal portion 14 and is formed as a column. Furthermore, the linear upper connection beam 16 is horizontally laid so as to connect the upper ends of the three columns 101 to each other, whereby the support frame 501A constitutes one rigid joint structure. The support frame 501A can be molded from concrete and can be mass-produced. In particular, by making the base plate part of the support platform of the entire support platform unit to have a common size and shape, it is possible to easily manufacture molded molds and dramatically reduce the cost of manufacturing the molds, and thus the support platform. Can be achieved. Further, a positioning bracket 18 of the solar cell panel 2 is attached to the upper surface side of the upper connecting beam 16. In the present embodiment, the positioning fitting 18 has a ring shape with a quadrangular cross section as shown in FIG. 3 and an inclined surface 181 with the upper surface having an installation inclination angle of the solar cell panel 2, and a slit groove 20 continuous in the longitudinal direction. It consists of a metal rail member made of stainless steel or the like. The positioning fitting 18 is formed with notches (not shown) for fixing to the upper connecting beam 16 at positions spaced in an appropriate longitudinal direction, and an insert nut provided on the upper connecting beam 16 is appropriately provided via the notch. It is fastened and fixed by a fastener or the like. Further, the panel is adjusted and fixed in the lateral direction by engaging and tightening an appropriate connection, fixing member or the like provided on the lower surface side of the solar cell panel 2 in the slit groove 20.

  2, 3, and 4, the bottom slab is divided into intermediate struts 101 b and is constituted by a long rectangular frame so as to have two adjacent hollow portions 7, and a longitudinal frame portion in which a reinforcing bar insertion hole 12 is formed. 8 and a short frame portion 9 are composed of a frame body connected in a square shape.

  In the present embodiment, the lower frame 501B has the same bottom plate portion configuration having the same outer shape and contour shape as the upper frame 501A. In FIG. 2, the lower gantry 501B includes a bottom plate portion 6 and a height support portion 11 similar to the upper gantry 501A, and has three columns 111 as the bottom plate portion 6 and the height support portion 11, and further includes a bottom plate. The part 6 is provided with two adjacent hollow parts 7, which are the same long rectangular frame shape as the upper frame 501A, and have the same configuration as the upper frame 5 in the outer shape and the contour shape. In the lower gantry 501B, the upper end height of the column 111 of the height support portion 11 is set lower than that of the upper gantry 501A. The upper connecting beam 16 and the positioning bracket 18 that commonly connect the upper ends of the respective columns 111 of the height support portion 11 are installed in the same configuration as the upper frame 501A. As a result, the solar cell panel is stably fixed with a predetermined slope by being installed on the upper and lower height support portions 10 and 11. The configuration of the support frame unit 5U is not limited to a pair of two. For example, there may be three, four, five or more cases. In that case, the upper end height is set in accordance with the slope when the solar panel to be installed is supported.

  2 and 3, six insertion reinforcing bars 22 are arranged in the gap S between the support bases 501A and 501B with both ends inserted into the bottom plate portion 6 of both support bases. That is, both ends of the insertion reinforcing bar 22 pass through the reinforcing bar insertion hole 12 of the longitudinal frame part 8 of the bottom plate part 6 where both the support bases face each other in the hollow holes 7a of the bottom plate parts of the support bases 501A and 501B, respectively. Protrusively provided. The end of the insertion rebar 22 may be a protruding portion that is in contact with the opposing abutting wall of the hollow holes 7a of the support bases 501A and 501B. The protruding portion is such that it stops in the hollow hole 7a at an intermediate position where it does not abut. It may be length. This length can also be set by appropriately adjusting when placing concrete on site. That is, it is possible to determine the protruding length corresponding to the variation in the width when adjusting the separation gap width between the support frames. At this time, the reinforcing bar insertion hole 12 is set to have a diameter size that is twice or more that of one reinforcing bar to be inserted. Therefore, as shown in FIG. A sufficient gap P is formed in the gap with the outer peripheral surface of the reinforcing bar. This void P allows the concrete to flow well and be filled with high density when the concrete material is placed on site. The insertion reinforcing bars 22 are inserted into the bottom plate portion 6 of all of the plurality of support frames forming the support frame unit 5U, and the bottom plate portions of all the support frames are integrated through the insertion reinforcing bars and the concrete material. That is, even when there are three, four, or more support platforms, the insertion reinforcing bars are arranged with all of the support platforms inserted. The length of the inserted reinforcing bar is set corresponding to the gap S between the support bases 501A and 501B. These are determined in the design stage such as the light receiving area and the inclination angle of the solar cell panel.

The solar cell panel support frame structure 1 of the present embodiment is completed for the first time at a specific construction site. That is, at the installation site of the solar cell panel, the upper support frame 501A and the lower support frame 501B separated by the gap S are arranged to face each other. At this time, all the inserted reinforcing bars 22 are arranged so as to pass through the reinforcing bar insertion holes 12 of the bottom plate portions on the opposite sides and project both ends into the hollow holes 7a. Next, concrete is placed and solidified in all the hollow portions 7 and the gaps S of the respective support frames. Then, the solar battery panel is supported and fixed on the support frame by the positioning brackets 18 and the fasteners of the upper support frame 501A and the lower support frame 501B.
The solidified portion of the concrete material placed in the gap S between all the hollow portions 7 of the support frame and the upper support frame 501A and the lower support frame 501B is the in-situ cast concrete unit 24.

  In this embodiment, the upper short side and the lower short side of the solar cell panel are arranged on the upper and lower columns 16 and 111 that support the solar cell panel on the upper and lower sides, as shown in FIG. Each of the solar cell panels is supported in the form of a line made of a rigid beam instead of a point, so that the support positioning in the height direction of the solar cell panel can be easily performed. That is, the inclination gradient setting operation of the solar cell panel including the installation positioning of the support frame, the unevenness adjustment, and the height adjustment can be smoothly performed in a short time at the installation site.

  In the embodiment, the solar cell panel 2 has, for example, six unit solar cell panels arranged in a vertically long rectangular shape, for example, an external shape having a vertical length of about 2 m and a horizontal length of about 1.5 m. The one protected by the outer frame is used. Each solar cell panel is provided with positive (+) and negative (-) terminal portions, and the solar cell panels are electrically connected in series, and power is taken out in parallel connection and converted into AC power. It is supplied to the outside by a conditioner or a power control device. In addition, the size of the solar cell panel is an example, and a panel having an arbitrary size can be installed.

  The in-situ bottom plate integration mechanism 3 includes at least one insertion rebar 22 inserted and arranged in common in the bottom plate portions of all support frames, all the hollow portions 7 of the support frames, the upper support frame 501A, and the lower support frame. And a cast-in-place concrete portion 24 placed in the gap S of the gantry 501B. When concrete is placed in the gap S between the support frame hollow portion 7, the upper support frame 501 </ b> A, and the lower support frame 501 </ b> B, the gap P between the reinforcing bar 22 and the insertion hole 12 is sufficiently large with respect to the occupied volume of the hole due to the reinforcing bar diameter. Since it has a volume, the concrete material thrown in from the bottom slab side and the gap S side easily enters the gap P, and is filled with a good density by compaction work. The bottom plate portion and the cast-in-place concrete portion are solidified integrally, thereby forming a rigid joint structure in which the entire support gantry unit 5U is integrated with a plurality of support gantry, thereby obtaining a high strength support gantry structure. Therefore, when the ground side is shaken such as an earthquake, it is difficult for external force to be directly applied to the solar panel, strengthening the solar panel, improving the durability of the solar power generation system, Efficiency improvement, cost reduction, and construction time reduction can be achieved.

  As shown in FIG. 6, for example, each support frame configuration of the above-described solar cell panel support frame structure of the first embodiment has the short frame portion 9 facing the direction in which the support frame is opposed to the example of FIG. The support base 501 </ b> Aa having a more stable structure may be formed by increasing the length of the opposite side of the support base from the rising position of the columns 101 and 111 in the bottom plate portion 6.

  Moreover, the shape of the reinforcing bar insertion hole 12 may be an hourglass shape in which the opening diameters at both ends are maximum and gradually narrow toward the center as shown in FIG. 7, and this corresponds to the external stress applied to the concrete after solidification. It can also be made possible.

  Next, a second embodiment of the present invention will be described with reference to FIGS. 8 to 11. The same members as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted. The basic configuration of the solar cell panel support frame structure 30 of the second embodiment is the same as that of the first embodiment, but in this embodiment, the support frames whose upper end heights are sequentially set lower are 501A and 501B. , 501C, and the three pieces form one support gantry unit 5U, and the insertion reinforcing bar inserted into the bottom plate portion 6 of the central support gantry 501C has its end stopped in the bottom plate portion They are not inserted in a state but are arranged in a penetrating state.

  In FIG. 10, the support base structure of the solar cell panel of the second embodiment has six horizontal through holes each aligned with the longitudinal frame portions 8 on both sides of the bottom plate portion 6 of the center support base 501C. ing. In FIG. 11, the bottom plate itself is not a long rectangular frame, but the three column base portions are joined in a skewered manner with the central beam member 26, and the insertion corresponding to the desired number of reinforcing bars to be disposed on the central beam member 26. The hole 12 is perforated. Also in the second embodiment, the construction can be completed in a short time by a simple construction method.

  The above-described support frame structure of the solar cell panel of the present invention can be applied not only directly on the ground but also on the rooftop of a building or a place where sunlight can be directly captured. The plurality of support frames arranged to face each other can be four or more. The number of reinforcing bars to be inserted into the inserted reinforcing bar is not limited to just one as in the embodiment, but may be two or more. However, the voids are more than twice the volume occupied by the inserted reinforcing bar diameter. It is necessary to use a reinforcing bar insertion hole that can form

  The support frame structure of the solar cell panel of the invention can be applied not only to a photovoltaic power generation facility using a large-scale solar cell panel but also to a small residence, business place, ship, and the like.
