Description

  The present invention relates to a mounting base for a solar panel (which means a solar battery panel or a solar battery module), and more particularly to a support base for installing the panel on a wall surface of a building or a structure.

Conventionally, for example, a facility has been proposed in which a large number of solar panels are arranged on the wall surface of a building such as a large three-dimensional parking lot to generate solar power.
In this case, solar panels are arranged in the vertical and horizontal directions on the wall surface of a building or structure (hereinafter referred to as “building”). A stand that can be supported by is required.
This is because the amount of power generated by solar panels installed on the wall usually drops to about 50%, so how to increase the power generation efficiency with the limited installation area on the wall is the issue of the frame manufacturer. This is because the inclination angle is important.

The applicant of the present application has already proposed such a wall support frame as shown in FIG.
FIG. 4 shows a side view of the conventional solar panel support frame, in which (A) shows the solar panel set at an angle of 45 degrees with respect to the horizontal plane, and (B) also shows the horizontal plane. On the other hand, an angle set at 65 degrees is shown, and (C) shows an object installed perpendicular to the horizontal plane.

  In addition, as shown in this example, the vertical angles of 45 degrees, 65 degrees, and the vertical state are exemplified in the frame installed on the wall surface of the building, which is sequentially arranged in the vertical direction and the horizontal direction. However, considering the angle of sunlight in the winter solstice and summer solstice, and also considering the influence of the installation base on the upper floor and the installation base on the lower floor, for example, depending on the installation area, the solar panel on the upper floor This is because the shadow of the upper floor panel minimizes the negative effects on the lower floor panel by setting the floor to a vertical state, setting it to 65 degrees on the middle floor and 45 degrees on the lower floor. .

The configuration of this conventional solar panel support frame is as follows.
A long upper crosspiece 52 is fixed horizontally to the wall surface W of the building using a fixing bracket 51.
In parallel with the upper horizontal beam 52, an elongated lower horizontal beam 53 is fixed to a lower horizontal beam supporting metal 54 that protrudes from the wall surface W at a right angle.

A reinforcing frame 55 is appropriately extended between the upper horizontal beam 52 and the lower horizontal beam 53.
A pair of vertical bars 56 whose upper ends can be connected and fixed to the upper horizontal bars 52 are arranged in parallel on the left and right.
A support arm 57 for supporting the lower part of the pair of vertical bars 56, 56 from below is provided.
That is, the upper ends of these support arms 57 are connected and fixed to the vertical beam 56, and the lower ends thereof are connected and fixed to the lower horizontal beam 53.

The solar panel S is fixed on the pair of vertical bars 56 and 56 arranged in parallel.
With the above configuration, the solar panel S, that is, the vertical beam 56 can be installed and fixed at an appropriate inclination angle or in a vertical state.
That is, as shown in FIG. 4A, it is approximately 45 degrees with respect to the horizontal plane, as shown in FIG. 4B, approximately 65 degrees with respect to the horizontal plane, and as shown in FIG. 4C. It can be installed perpendicular to the horizontal plane.

In this case, the vertical crosspiece 56 used in FIGS. (A) and (B) has a different top end shape.
In addition, as the support arm 57, one having a different shape at the lower end portion and one having a different length are used.

The reason for this is to support the vertical beam 56 at different inclination angles and to have a shape that fits the upper horizontal beam 52 and the lower horizontal beam 53 appropriately.
Further, in order to install the solar panel S shown in FIG. 5C in the vertical state, the support arm 57 is not required, the vertical beam 56 is directly fixed to the upper horizontal beam 52 and the lower horizontal beam 53, and The shape of the upper end portion of the crosspiece 56 is also different from that shown in FIGS.

As described above, in the conventional solar panel support frame, in order to install the solar panel in the three states of 45 degrees, 65 degrees, and vertical with respect to the horizontal plane as described above, the vertical beam and the support arm Therefore, three combinations of the three types are required.
In other words, each component is the same, but the combination of three different shapes of components is required by appropriately changing the end shape and length of each component.

Therefore, in the present invention, the solar panel can be installed at a desired appropriate inclination angle, can be installed in a vertical state, and for this purpose, each component can be realized without requiring different shapes. The issue is to provide.
By realizing this problem, it will greatly contribute to the ease of manufacturing and the ease of construction, which are the basic problems of the past.
In addition, the solar panel can be adjusted to the optimum inclination angle from the upper floor to the lower floor, depending on the installation area and the height of the building. It will be possible.

In order to solve the above-mentioned problems, a first aspect of the present invention is a support frame for installing a solar panel on a wall surface of a building or a structure, and the support frame is horizontally disposed on the wall surface of the building or the structure. An upper horizontal rail to be fixed, a pair of vertical rails whose upper ends are connected and fixed to the upper horizontal rail, and arranged substantially parallel to the left and right, and an upper end portion are supported in order to support these vertical rails at an appropriate inclination angle. A pair of inclined support arms that are connected and fixed to these vertical beams, a lower horizontal beam that is connected and fixed at the lower end of these inclined support arms, and arranged substantially parallel to the upper horizontal beam, and a tip of the lower horizontal beam The solar panel is supported and fixed to the pair of vertical rails, and the lower horizontal rail bracket is used for a building or a structure. Can enter and exit in the direction perpendicular to the wall Is fixed so as, whereby said possible supporting fixed at an appropriate inclination angle solar panels, it can be fixed at an appropriate position of the fixed positions of the upper and the vertical bar of the inclined support arm from the lower end of the vertical bar to its upper position Thus, the solar panel wall surface support frame is characterized in that the inclination angle of the solar panel can be changed .

According to a second aspect of the present invention, in the first aspect described above, the fixing position of the upper end portion of the inclined support arm and the vertical beam is appropriately changed, and the protruding length from the wall surface of the lower horizontal beam receiving bracket is changed. It is a solar panel wall surface support stand characterized in that the inclination angle of the solar panel can be changed in a range from a substantially horizontal state to a substantially vertical state by appropriately changing.

According to a third aspect of the present invention, in the first or second aspect of the present invention, when the upper crosspiece and the vertical crosspiece are connected and the inclined support arm and the lower horizontal crosspiece are connected, the cross section is substantially U-shaped. The solar panel wall surface support frame is characterized in that a vertical beam and an inclined support arm are rotatably connected to and fixed to an upper horizontal beam and a lower horizontal beam, respectively, via a coupling fitting.

According to a fourth aspect of the present invention, in the first to third aspects of the invention, a hook portion for temporarily hooking the vertical beam on the upper horizontal beam is provided at the upper end of the vertical beam. This is a wall support frame for solar panels.

According to a fifth aspect of the present invention, in any one of the above-described inventions, a long covering member having a substantially L-shaped cross section that covers the upper end of the upper horizontal rail and the vertical rail is further added and fixed. This is a featured wall support frame for solar panels.

  In the first one of the present invention, the component comprises an upper horizontal beam and a lower horizontal beam, a pair of left and right vertical beams, a pair of inclined support arms, and a lower horizontal beam receiving bracket that supports the lower horizontal beam, A pair of vertical bars, that is, a solar panel can be supported and fixed using these constituent members at a predetermined inclination angle.

In that case, it is only necessary to fix the lower horizontal rail receiving bracket for fixing the lower horizontal rail at the tip portion by moving it in and out of the wall surface of the building or structure in the horizontal direction, that is, in a direction perpendicular to the wall surface. .
More specifically, by projecting the lower horizontal rail metal fitting more from the wall surface, the inclination angle of the vertical rail and the solar panel becomes smaller with respect to the horizontal plane. By immersing and fixing to the wall surface, the inclination angle of the vertical beam and the solar panel becomes a larger inclination angle (an angle approaching vertical) with respect to the horizontal plane.

In addition, since the upper and lower horizontal rails are long in the longitudinal direction, a plurality of pairs of vertical rails can be arranged on both horizontal rails, that is, a plurality of solar panels. Can be arranged.
Since the distance between the pair of vertical bars can be set freely, it is possible to correspond to different sizes of solar panels from different manufacturers.
Arranging rectangular solar panels in a vertically long position or a horizontally long position can be freely selected and handled.
Furthermore, in the present invention, the wall support gantry can be unitized in advance because the horizontal beam, the vertical beam, and the inclined support arm are assembled in a lattice shape in front view, and the construction can be simplified. .

Further , the fixing position of the upper end of the inclined support arm and the vertical beam can be fixed at an appropriate position from the lower end of the vertical beam to the upper position thereof, and the inclination angle of the solar panel can be changed. The inclination angle of the vertical beam and the solar panel can be adjusted by changing the attachment position of the upper end portion of the inclined support arm with the vertical beam along with the entry and exit of the lower horizontal frame bracket.

In the second of the present invention, in the first aspect, while using the same components as support cradle according to the first invention, the fixed position between the upper and the vertical bar of the inclined support arm appropriately The inclination angle of the solar panel can be changed in a range from a substantially horizontal state to a substantially vertical state by changing the protrusion length from the wall surface of the lower horizontal crosspiece fitting as appropriate.
Therefore, according to the area where the building is installed or its height, the solar panel can be installed with the inclination angle of the solar panel set to an optimum angle.

According to the third aspect of the present invention, the upper crosspiece and the vertical crosspiece are connected to each other, and the inclined support arm and the lower horizontal crosspiece are connected to each other via a connection fitting having a substantially U-shaped cross section. It is characterized in that it can be connected and fixed movably.
That is, in the present invention, the upper end of the vertical beam and the lower end of the inclined support arm need to be able to be pivotably connected to the upper horizontal beam and the lower horizontal beam at the time of installation work, respectively. After adjusting and determining the above, these connections are fixed by bolting.
In order to perform such a configuration more appropriately, the above-described connecting bracket having a substantially U-shaped cross-section is used, and the embodiment is limited in a more specific manner.

The fourth aspect of the present invention is characterized in that a hooking portion for temporarily hooking the vertical beam on the upper horizontal beam is provided at the upper end of the vertical beam.
For example, when a steel mold having a U-shaped cross section is used as a vertical beam, the hook is arranged in the vertical state when the vertical beam is arranged in a vertical state, The opposite side surface can be extended upward and bent sideways, and the tip can be further bent downward to form a hook portion.
This hooking part should be hooked on the upper horizontal rail at the time of construction, so that the vertical rail is temporarily hooked on the upper horizontal rail before being fixed to the upper horizontal rail, and used as temporary placement or temporary fixing. It becomes very convenient for construction.

In the fifth aspect of the present invention, a long covering member having a substantially L-shaped cross section covering the upper crosspiece and the upper end of the vertical crosspiece is further fixed, and the appearance is further improved. In addition, it is intended to prevent rainwater or the like from accumulating inside the upper cross rail using, for example, a steel having a substantially U-shaped cross section.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 is a side view according to an embodiment of the wall support frame for solar panels of the present invention, and shows an inclination angle of approximately 45 degrees.
In FIG. 1 and the subsequent drawings, the connecting portions of the constituent members are respectively drawn in a solid line in a transparent state for the sake of clarity and easy understanding.

  The solar panel wall surface support frame according to the present invention includes an upper horizontal beam 11 that is fixed substantially horizontally to the wall surface part W, and a pair of vertical beams 12 and 12 whose upper ends are fixed to the upper horizontal beam 11, A pair of inclined support arms 13 and 13 whose upper ends are fixed at the lower ends of these vertical beams 12 and 12, a lower horizontal beam 14 to which the lower ends of these inclined support arms 13 and 13 are fixed, and It comprises at least two elongate lower horizontal crosspiece metal fittings 15 and 15 for fixing the lower horizontal crosspiece 14 at its tip.

The upper horizontal rail 11 and the lower horizontal rail 14 are arranged substantially in parallel and substantially horizontally, and are each formed from a long steel mold. Here, a substantially U-shaped cross section is used, and the opening is arranged on the left side in the figure.
When connecting the upper crosspiece 11 and the upper end of the vertical crosspiece 12, a bracket 16 having a substantially U-shaped cross section is used so that the vertical crosspiece 12 can be tilted freely.
More specifically, an opening portion having a substantially U-shaped cross section is arranged on the left side in the figure, and the standing portions on both sides hold the upper end portion of the vertical rail 12 inside.

Similarly, when connecting to the lower end portion of the inclined support arm 13, a metal fitting 17 having a substantially U-shaped cross section is used in order to allow the inclined support arm 13 to be freely inclined.
The configuration and arrangement of the metal fitting 17 are the same as those of the metal fitting 16.
The lower horizontal rail bracket 15 is arranged so as to be able to enter and exit horizontally from the wall surface portion W, that is, in a direction perpendicular to the wall surface portion W, and is fixed to a building support P.

With the above-described configuration, the tip end portion of the lower horizontal crosspiece bracket 15 protrudes from the wall surface portion W and is fixed, whereby the inclination angle θ of the pair of vertical crosspieces 12 and 12 becomes a smaller angle.
That is, the inclination angle θ is the inclination angle of the vertical beam 12 with respect to the lower horizontal rail receiving metal fitting 15. In other words, this inclination angle is the inclination angle of the vertical beam 12 with respect to the horizontal plane, but in FIG. It shows an aspect that is fixed in degrees.

In this embodiment, the inclination angle 45 degrees of the vertical beam 12 is the smallest inclination angle that can be set. This is because the lower horizontal rail bracket 15 is projected from the wall surface W to the maximum. However, the inclination angle can be further reduced by increasing the protruding length.
The solar panel S is placed and fixed on the pair of vertical bars 12 and 12.
That is, in the wall surface support frame shown in FIG. 1, the solar panel S is fixed to the wall surface portion W at an inclination angle of about 45 degrees with respect to the horizontal plane.

FIG. 2 is a side view according to the embodiment, and shows an inclination angle of approximately 65 degrees.
The wall surface support frame shown in FIG. 2 has the same configuration as that of the above embodiment, that is, the structural members are completely the same, and the lower horizontal rail 15 is most immersed in the wall surface W. 1 is different from that of the embodiment of FIG.

  In other words, the lower horizontal bracket 15 shown in this figure is fixed to the column P so that it does not protrude most from the wall surface portion W. As a result, the lower end portion of the inclined support arm 13 is the most wall surface portion. Similarly, the lower end of the vertical beam 12 is positioned closest to the wall surface W, and therefore the inclination angle θ of the vertical beam 12 is also a larger angle. In this figure, the inclination is approximately 65 degrees. It is an angle.

Thereby, the inclination angle of the solar panel S fixed to the vertical rail 12 is also set to about 65 degrees.
As described above, in the present invention, the inclination angle θ of the vertical beam 12, that is, the solar panel S can be easily set by simply changing the fixing position of the lower horizontal beam receiving bracket 15 with the same component, And it can be changed.

  In this embodiment, as shown in FIGS. 1 and 2, the inclination angle θ can be changed in the range of 45 degrees to 65 degrees by changing the fixing position of the lower horizontal crosspiece bracket 15. However, in the present invention, the inclination angle of the vertical beam 12 can also be changed by changing the connecting position of the upper end of the inclined support arm 13 and the vertical beam 12 from the lowermost end of the vertical beam 12 to the upper position thereof. The range of θ can be changed further widely.

FIG. 3 is a side view according to the embodiment, showing a solar panel installed in a vertical state.
The wall support frame shown in FIG. 3 also uses the same constituent members as those in the above embodiment. However, in the aspect shown in this figure, the vertical rail 12 is arranged in a vertical state, and is supported in an inclined manner. An upper end portion of the arm 13 is fixed to an intermediate portion of the vertical beam 12.

That is, in the state shown in this figure, the vertical beam 12 and the inclined support arm 13 are superposed on each other, and the vertical beam 12 is in a substantially vertical state by both the vertical beam 12 and the inclined support arm 13. In other words, it is arranged in parallel with the wall surface portion W and is fixed to the lower horizontal rail 14.
In this state, the fixing position of the lower horizontal rail bracket 15 is the same as the fixing position of FIG.

  Therefore, the inclination angle of the vertical beam 12 and the solar panel S is sequentially changed from 65 degrees to 90 degrees by sequentially shifting the fixing position of the upper end portion of the inclined support arm 13 to the vertical beam 12 upward. It can be made.

  In the embodiment of the present invention shown in FIGS. 1 to 3, the inclination angle of the solar panel S can be changed and set in the range of 45 degrees to 90 degrees with respect to the horizontal plane. By making it longer than the protruding length from the wall surface portion W of the horizontal rail receiving bracket 15, the upper end of the inclined support arm 13 is sequentially moved upward from the lower end to the upper end of the vertical rail. Thus, the inclination angle can be changed between the horizontal state and the vertical state.

More specifically, when the upper end of the inclined support arm 13 and the vertical beam 12 are connected and fixed, a bolt hole provided on the vertical beam 12 side is formed into a long hole, thereby continuously increasing the inclination of the vertical beam 12. It becomes possible to change.
Furthermore, as the inclined support arm 13, it is possible to adopt a configuration in which the length can be extended or contracted.
Thereby, the inclination angle of the solar panel to be installed on the wall surface can be set to a desired angle in a range from a maximum of 90 degrees (vertical state) to 0 degree (horizontal state) with respect to the horizontal plane.

  In the present invention, as described above, the inclination angle of the vertical beam can be appropriately changed by the same constituent member. However, as described above, when the upper end of the vertical beam 12 and the upper horizontal beam 11 are connected, the cross section is substantially omitted. A U-shaped metal fitting 16 and a metal fitting 17 having a substantially U-shaped cross section are used for connecting the lower end of the inclined support arm 13 and the lower horizontal rail 14.

On the other hand, the vertical beam 12 and the inclined support arm 13 side are connected to each other using a steel mold having a substantially U-shaped cross section.
And in order for the upper end part of the vertical beam 12 and the lower end part of the inclination support arm 13 to rotate, one bolt hole of the bolt hole provided in the said metal fittings 16 and 17 is formed in an arc-shaped long hole, Fixing with bolts and nuts is possible.

More specifically, in the above-described embodiment of the present invention, two sets of bolts and nuts are used for the fixing, and one bolt and nut is used as a rotation shaft, and the other bolt and nut is fixed. The fastening position can be changed by an arc-shaped elongated hole.
Thereby, the inclination angle of the vertical frame 12 and the inclination support arm 13 can be changed.

In the present invention, since the upper horizontal frame 11 and the lower horizontal frame 14 use long steel molds, the distance between the pair of vertical frames 12, 12 can be freely set, It is possible to deal with different widths of the solar panel S.
Similarly, the length of the vertical frame 12 can be freely set, and the solar panel S can be freely adapted to different lengths in the vertical direction.

As mentioned above, although embodiment of this invention was described, the design can be variously changed as follows.
First, the size, the cross-sectional shape, etc. of the upper horizontal beam, the lower horizontal beam, the vertical beam, the inclined support arm and the lower horizontal beam receiving metal used in the present invention can be designed completely freely.

Other configurations are free as long as the upper end of the vertical beam can be pivotably connected to the upper horizontal beam.
Similarly, the lower end portion of the vertical beam and the inclined support arm can be connected to each other so as to be rotatable and can be fixed, and other configurations and forms are completely free.

Further, the lower end portion of the inclined support arm can be pivotally connected to the lower horizontal rail and can be fixed in any other form as long as it can be fixed.
The lower crosspiece metal fitting may also be a steel mold or a square steel pipe having a U-shaped cross section.
The upper horizontal beam and the lower horizontal beam may also be steel square tubes.

It is desirable to provide a large number of bolt holes provided in the lower horizontal rail bracket at shorter intervals.
This is because the protruding length from the wall surface portion of the lower horizontal crosspiece bracket can be protruded by a shorter length, and the inclination angle of the vertical crosspiece can be changed and set at a finer angle.
However, in the present invention, since it is possible to adopt a configuration that can continuously change the connection fixing position of the vertical beam and the inclined support arm, it is sufficient that the fixing position of the lower horizontal rail metal fitting can be changed, The interval can be set freely as appropriate.

A fixing bracket for fixing the upper crosspiece to the wall surface portion can also be freely selected and used.
A hook portion for hooking the upper end portion of the vertical beam to the upper horizontal beam can be formed to temporarily fix or temporarily place the upper beam to the upper horizontal beam.
As described above, when a steel mold having a U-shaped cross section is used as the vertical rail, the hook portion is arranged in a vertical state with the vertical rail arranged in the horizontal direction, and the opposite side to the opening. It is possible to form a hook portion by extending the side surface of the plate and bending it sideways and bending the tip portion further downward.
Finally, in the present invention, when a substantially L-shaped or a substantially U-shaped cross-section is adopted as the cross-sectional shape of each member constituting the wall support frame, it has a cross-sectional shape that makes it difficult for water to accumulate. Therefore, it is excellent in high durability and anti-corrosion properties.

  As described above, according to the present invention, by using the same component member and changing the mounting position of a part of the component member, the inclination angle of the solar panel can be easily set within a range of 0 to 90 degrees. It was possible to provide a support frame for the wall of a building that can be set and changed.
