Description

  The present invention relates to a photovoltaic power generation panel installation system and an installation method, and more particularly to a photovoltaic power generation panel installation system and an installation method that are installed on the ground including an inclined surface such as a hill or a mountain.

  A photovoltaic power generation panel refers to a panel incorporating a solar cell module. This solar cell module immediately converts light energy received on the module surface into electricity using the photovoltaic effect. That is, the light energy incident on the inside of the solar cell module is directly absorbed by the electrons, led to an electric field provided in advance, and output as electric power to the outside of the solar cell module. A panel-shaped product unit in which a plurality of solar cell modules are connected in series and parallel to obtain necessary voltages and currents is referred to as a photovoltaic power generation panel or a solar cell panel. Silicon, CIS (copper, indium, and selenium) or the like is used as a material that converts light energy into electricity in the solar cell module. This silicon is roughly classified into crystalline silicon and amorphous silicon.

Projecting from the head of the self-drilling rod to cure and solidify the grout material, insert a fixing member into the head of the tendon from above the pressure plate installed on the ground, hold the tendon in tension, and tighten the pressure plate It is described that it is pressed against the ground to counteract the force of the ground.

Patent No. 3841006

  Solar power generation is a power generation method that utilizes sunlight, which is clean energy. This solar power generation system has features such as ease of daytime power demand peak and reduction of greenhouse gas emissions, and is expected as a kind of renewable energy. This solar power generation panel is generally installed mainly on the roof surface or wall surface of a building. Thus, the photovoltaic power generation system is increasing in demand as a system that can be installed without occupying land by being integrated with a roof or a wall of a building. In recent years, solar power generation systems have been in the limelight as renewable energy, and an increasing number of solar power generation panels are installed on flat ground to secure more power. For example, they are installed in deserts. There is a solar power plant. However, it is not easy to secure a place to install a large number of photovoltaic panels in our country where there are few flat lands and the land use rate is low. Therefore, it is desired to install a solar power generation panel not only on a flat ground where the installation of the solar power generation panel is relatively easy, but also on an inclined surface such as a hill or a mountain.

  When installing a solar power generation panel on an inclined surface such as a hill or a mountain, a method for fixing the solar power generation panel to an inclined surface with poor workability must be taken. That is, a strong fixing bolt must be installed on the inclined surface. However, there is a problem that it is extremely difficult to ensure the construction accuracy of the fixing bolts provided on site with respect to the dimensional accuracy of the photovoltaic power generation panel itself.

  For fixing bolts provided on the inclined surface, three types of construction accuracy based on the inclined surface are important. The first construction accuracy is an error in the coordinate position of the fixing bolt with respect to the inclined surface. It is relatively easy to obtain the accuracy by measuring the coordinate position of the fixing bolt with respect to the inclined surface with a measuring instrument or a measuring instrument. For the adjustment of the coordinate position, a fixing bolt is inserted into the drill hole and the space between the fixing bolts is filled with the grout. The position of the fixing bolt can be adjusted by shifting the position until the grout is solidified.

  The second construction accuracy is an error in the height position of the fixing bolt in a direction substantially orthogonal to the inclined surface. That is, the inclined surface is generally uneven, and it is difficult to obtain the accuracy of the height position where the fixing bolt enters and exits in a direction substantially orthogonal to the inclined surface. If a harmful construction error occurs in the height position of the fixing bolt, it becomes difficult to connect the fixing bolt to the panel support frame that supports the photovoltaic power generation panel, and it is necessary to repair the fixing bolt.

  The third construction accuracy is the verticality of the fixing bolt in a direction substantially orthogonal to the inclined surface, that is, “inclination”. Although it is possible to measure the verticality of the fixing bolt on the inclined surface, it is difficult to ensure its accuracy. If a construction error harmful to the verticality of the fixing bolt occurs, it becomes difficult to connect the fixing bolt to the panel support frame that supports the photovoltaic power generation panel, and it is necessary to repair the fixing bolt.

  An object of the present application is to solve such a problem and provide a photovoltaic power generation panel installation system and an installation method for easily and accurately installing a photovoltaic power generation panel on a ground surface including an inclined surface such as a hill or a mountain. .

  In order to achieve the above object, a photovoltaic power generation panel installation system according to the present invention includes a photovoltaic power generation panel that is installed supported by a panel support frame, and a first panel that connects to the panel support frame and penetrates a fixing bolt. A connecting member having a through hole, and one end inserted into a drilling hole provided on the ground, and the other end fixed to the connecting member by insertion angle adjusting means for sandwiching the connecting member from both side surfaces of the first through hole. A cylindrical adjustment tube including a bolt, a cylindrical portion having an opening end penetrating into the ground, a second through hole through which the fixing bolt penetrates, and a bottom plate portion having an adjustment nut engaged with the fixing bolt; And the insertion angle of the fixing bolt is adjusted by the rotation angle of the insertion angle adjusting means, and the insertion level of the fixing bolt is adjusted by the amount of penetration of the cylindrical adjustment tube into the ground.

  With the above configuration, the photovoltaic power generation panel installation system adjusts construction errors such as the installation position (coordinate position), penetration amount (height position), insertion angle (verticality) of the fixing bolt inserted into the ground. A photovoltaic power generation panel can be easily and accurately installed on the ground including slopes such as hills and mountains. That is, the fixing bolt is connected to the panel support frame via the connection member, and the fixing bolt is inserted into the drilling hole provided on the ground by the insertion angle adjusting means for sandwiching the connection member from both side surfaces of the first through hole. The insertion angle is adjusted. Thereby, the construction error regarding the insertion angle (verticality) of the fixing bolt can be adjusted, and the photovoltaic power generation panel can be easily connected to the fixing bolt. Further, by fixing the fixing bolt in the cylindrical adjustment tube, the penetration amount (height position) of the fixing bolt into the ground among the fixing bolt installation errors can be adjusted by the cylindrical adjustment tube. Thereby, installation positions, such as the installation height of a photovoltaic power generation panel, and the angle of an installation surface, can be adjusted. Further, as will be described later, the fixing bolt exposed to the ground portion can be reinforced by the cylindrical adjustment tube. Thus, for example, even on the ground such as an inclined surface with poor construction conditions such as a hill or a mountain, the photovoltaic power generation panel can be installed easily and accurately.

  Further, in the photovoltaic power generation panel installation system, the insertion angle adjusting means is a spherical washer and a spherical nut, or a washer and nut with an inclined surface, and the attachment angle of the connection member to the fixing bolt can be adjusted by the spherical surface or the inclined surface. It is preferable. Thereby, the construction error regarding the insertion angle (verticality) of the fixing bolt can be adjusted, and the photovoltaic power generation panel can be easily connected to the fixing bolt. The insertion angle adjusting means is a general washer and nut, and may be means for adjusting the insertion angle by causing the fixing bolt to be inclined by the difference between the diameter of the fixing bolt and the diameter of the hole of the washer. .

  In the photovoltaic power generation panel installation system, it is preferable that the adjustment nut provided on the connection member side of the second through hole also serves as a nut for connecting the fixing bolt and the connection member. The adjustment nut, the fixing bolt, and the nut for connecting the connection member are also used, and the photovoltaic power generation panel installation system can be installed with a simpler configuration.

Further, in the photovoltaic power generation panel installation system, the fixing bolt is provided in the bottom plate portion having the second through-hole through which the fixing bolt penetrates and the cylindrical portion of the cylindrical adjustment pipe, and the third fixing bolt penetrates. It is preferable to be fixed at the center position of the cross section of the cylindrical adjustment tube by a steady spacer having a through hole. As described above, the fixing bolt is supported at two points, that is, the bottom plate portion having the second through hole penetrating through and the steady spacer having the third through hole penetrating through the fixing bolt, and the position thereof is fixed. The steady stopper serves as a steady stop for the cylindrical adjustment tube, and the position of the fixing bolt in the cylindrical adjustment tube is fixed to the position of the core of the cylindrical adjustment tube. In this way, the fixing bolt penetrates the core of the cylindrical adjusting tube inside the cylindrical adjusting tube, so that the accuracy of the position and inclination of the fixing bolt inside the cylindrical adjusting tube can be secured. The installation position such as panel installation height and installation surface angle can be easily adjusted.

  Further, in the photovoltaic power generation panel installation system, the adjustment nut provided on the connecting member side of the second through hole is fixed to the bottom plate portion, and the cylindrical adjustment tube penetrates into the ground by rotating the cylindrical adjustment tube. It is preferred that the amount be adjusted. Thus, since the adjustment nut on the connection member side is fixed to the bottom plate portion, the cylindrical adjustment tube is rotated by the rotation of the adjustment nut. The insertion level of the fixing bolt can be adjusted by rotating this cylindrical adjusting tube and penetrating it into the ground.

  In addition, in the photovoltaic power generation panel installation system, a grout inlet is provided in the cylindrical adjustment pipe, and the grout inlet to the inside of the cylindrical adjustment pipe inserted into the drilling hole into which the fixing bolt is inserted and the grout are inserted. Is preferably injected. Thereby, the fixing bolt exposed to the ground part is reinforced by the grout restrained by the cylindrical adjustment pipe. Further, the grout injected into the drilling hole in which the fixing bolt is inserted is continuously injected into the cylindrical adjustment tube, so that the inside of the drilling hole and the cylindrical adjustment tube are integrally reinforced. Furthermore, it can suppress and resist against the blowing force by the wind of a photovoltaic power generation panel mainly by the peripheral frictional resistance of a grout and a natural ground.

  In addition, the photovoltaic power generation panel installation system is provided with adjustment nuts on the outside and inside of the second through-hole, respectively, and the inside adjustment nut is rotated from the grout inlet in the same manner as the adjustment nut on the outside. It is preferable that the amount of penetration of the cylindrical adjustment tube into the ground is adjusted. Thus, before injecting grout into the grout inlet, the adjustment nut on the inner side can be rotated from the grout inlet, and the insertion level of the fixing bolt can be adjusted by the amount of penetration of the cylindrical adjustment tube into the ground. .

  In order to achieve the above object, a solar power generation panel installation method according to the present invention includes a step of inserting a fixing bolt into a drilling hole provided in the ground, and a second step provided in the bottom plate portion of the cylindrical adjustment tube. A step of causing the fixing bolt to pass through the through hole and penetrating the opening end of the cylindrical adjustment pipe into the ground, a step of adjusting the amount of penetration of the cylindrical adjustment pipe into the ground, and a panel support frame for supporting the photovoltaic power generation panel Connecting to the fixing bolt. Furthermore, the method further includes a step of adjusting a connection angle between the connection member and the fixing bolt.

  With the above configuration, the photovoltaic power generation panel installation method takes steps to absorb construction errors such as the installation position of the fixing bolt inserted into the inclined surface, the penetration amount, and the insertion angle, such as hills and mountains. The solar power generation panel can be easily and accurately installed on the ground including the inclined surface. That is, the fixing bolt is connected to the panel support frame via the connection member, and the fixing bolt is inserted into the drilling hole provided on the ground by the insertion angle adjusting means for sandwiching the connection member from both side surfaces of the first through hole. The insertion angle is adjusted. Thereby, the construction error regarding the insertion angle (verticality) of the fixing bolt can be adjusted, and the photovoltaic power generation panel can be easily connected to the fixing bolt. Further, by fixing the fixing bolt in the cylindrical adjustment tube, the penetration amount (height position) of the fixing bolt into the ground among the fixing bolt installation errors can be adjusted by the cylindrical adjustment tube. Thereby, installation positions, such as the installation height of a photovoltaic power generation panel, and the angle of an installation surface, can be adjusted.

  Moreover, it is preferable that the photovoltaic power generation panel installation method includes a step of adjusting the amount of penetration of the cylindrical adjustment pipe into the ground by rotating an adjustment nut that engages with the fixing bolt. Thereby, the construction error about the penetration amount (height position) of the fixing bolt can be easily adjusted with high accuracy. That is, the cylindrical adjustment tube can adjust the amount of penetration into the ground by pushing and pulling the cylindrical portion, but by pushing the pulling bolt against the cylindrical adjustment tube by rotating the adjustment nut. It is possible to adjust the penetration amount more delicately. Thereby, the installation height of a photovoltaic power generation panel and the angle of an installation surface can be adjusted easily and accurately.

  Furthermore, the photovoltaic power generation panel installation method fixes an adjustment nut provided on the connecting member side of the second through hole of the bottom plate portion to the bottom plate portion, and rotates the cylindrical adjustment tube to ground the cylindrical adjustment tube. It is preferable to provide a step of adjusting the amount of penetration. Thereby, construction errors such as the insertion angle (verticality) of the fixing bolt can be adjusted, and the installation height of the photovoltaic power generation panel and the angle of the installation surface can be adjusted easily and accurately.

  As described above, according to the photovoltaic power generation panel installation system and the installation method according to the present invention, for example, a photovoltaic power generation panel can be simply and accurately installed on the ground including an inclined surface such as a hill or a mountain. An installation system and an installation method can be provided.

(Solar power generation panel installation system)
Below, it demonstrates in detail about embodiment of the solar power generation panel installation system which concerns on this invention using drawing. FIG. 1 shows a schematic configuration of one embodiment of a photovoltaic power generation panel installation system 1 according to the present invention. FIG. 2 shows an enlarged schematic configuration of one embodiment of the fixing method of the photovoltaic power generation panel. The photovoltaic power generation panel installation system 1 is mainly composed of a photovoltaic power generation panel 2, a panel support frame 3, a fixing bolt 4, and a cylindrical adjustment pipe 5 which is one embodiment of a penetration amount adjusting means for the fixing bolt 4. .

  In this specification, the case where the photovoltaic power generation panel 2 is installed on the inclined surface 13 such as a hill or a mountainous area, which is stricter than the flat ground, will be described. That is, as shown in FIG. 1, in the photovoltaic power generation panel installation system 1, fixing bolts 4 are provided in the soil of the inclined surface 13 at a predetermined interval, and are connected to the fixing bolt 4 via the panel support frame 3. The rectangular solar power generation panels 2 fixed in place are installed side by side. However, the present solar power generation panel installation system 1 is not limited to such inclined surfaces 13 such as hills and mountains, but is also applied to flat ground and ground with small undulations.

  The panel support frame 3 supports the photovoltaic power generation panel 2. The panel support frame 3 is connected to the fixing bolt 4 via the connection member 17. The connecting member 17 is, for example, a steel material such as an angle material or a Z-shaped steel, but is not limited thereto, and may be a channel-shaped steel, for example. As shown in FIGS. 8 and 11, the panel support frame 3 includes a purlin member 24 that directly receives the photovoltaic power generation panel 2, and a column member 21 and a beam member 22 that receive the purlin member 24 and constitute a framework (frame). And diagonal members 23 and the like.

  As shown in FIG. 2, the fixing bolt 4 is inserted into a hole 6 provided at one end of the inclined surface 13. The other end is connected to the connection member 17 via the insertion angle adjusting means 12. Here, the insertion angle adjusting means 12 includes a spherical washer 12a and a spherical nut 12b having curved surfaces in two orthogonal axes as shown in FIG. 4, or a tapered washer 12a and nut inclined in one axis shown in FIG. 12b is generally used. Further, the insertion angle adjusting means 12 is a general washer 12a and nut 12b, and adjusts the insertion angle by causing the fixing bolt 4 to be inclined by the difference between the diameter of the fixing bolt 4 and the diameter of the hole of the washer 12a. It may be a means. The connecting member 17 has a first through hole 7a that allows the fixing bolt 4 to pass therethrough, and a tapered washer and a nut, which is one embodiment of the insertion angle adjusting means 12, are connected from both side surfaces of the first through hole 7a, respectively. It attaches so that the member 17 may be inserted | pinched. As shown in FIG. 2, the nut 12 b that connects the fixing bolt and the connection member may be shared by the adjustment nut 14. In this embodiment, the fixing bolt 4 uses a different diameter reinforcing bar or a different diameter steel bar, but is not limited thereto, and may be a general reinforcing bar, a PC steel bar, a PC steel wire, a fiber reinforcing material, or the like. The fixing bolt 4 may be constructed by providing a drilling hole 6 on the inclined surface 13 and inserting the fixing bolt 4 into the drilling hole 6. Alternatively, a bit for the drilling hole 6 may be provided at the tip of the fixing bolt 4. The fixing bolt 4 may be inserted while drilling the attachment and the inclined surface 13. Thus, the construction of the fixing bolt 4 is selected according to the construction conditions such as the ground layer of the inclined surface 13. The fixing bolt 4 is inserted in a direction substantially perpendicular to the virtual inclination angle of the inclined surface 13.

  In FIG. 3, the detail of the cylindrical adjustment pipe | tube 5 which is one Example of the penetration amount adjustment means is shown. 3A is a cross-section of the cylindrical adjustment tube 5, FIG. 3B is a cross-sectional view taken along line AA in FIG. 3A, and FIG. 3C is a cross-sectional view of FIG. It is a BB cross section. The cylindrical adjustment tube 5 includes a bottom plate portion 11 having a second through-hole 7 b through which the fixing bolt 4 passes, and a cylindrical portion 10 in which an opening end 20 is inserted into the inclined surface 13. The tubular part 10 is connected. In the second through hole 7 b of the bottom plate portion 11, the bottom plate portion 11 is provided with an adjustment nut 14 that engages with the fixing bolt 4 outside the cylindrical adjustment tube 5. As shown in FIG. 2, the adjustment nut 14 provided on the connection member 17 side of the second through hole 7b also serves as a nut 12b for connecting the fixing bolt and the connection member. Thereby, the adjustment nut 14 and the nut 12b are combined, and this photovoltaic power generation panel installation system 1 can be installed with a simpler configuration. In addition, an anti-sway spacer 16 having a grout passage hole 18 on the plate surface is provided inside the cylindrical portion 10. The steady rest spacer 16 has a third through hole 7c through which the fixing bolt 4 passes.

  Thus, the fixing bolt 4 is provided in the bottom plate portion 11 having the second through hole 7b through which the fixing bolt 4 passes, and the cylindrical portion 10 of the cylindrical adjustment tube 5, and the third through hole through which the fixing bolt 4 passes. It is fixed to the center position of the cross section of the cylindrical adjustment tube 5 by the steady spacer 16 having the hole 7c. That is, the fixing bolt 4 is supported at two points of the two through holes 7b and 7c. Thereby, the steady rest spacer 16 functions as a steady rest for the cylindrical adjustment tube 5, and the position of the fixing bolt 4 in the cylindrical adjustment tube 5 is set at the core of the cross section of the cylindrical adjustment tube 5. The accuracy of the position and inclination of the fixing bolt 4 inside the tube 5 is ensured. As shown in FIG. 3, the cylindrical adjustment tube 5 includes an adjustment nut 14 on the inner side of the bottom plate portion 11 of the cylindrical adjustment tube 5, and the fixing bolt 4 is cylindrically adjusted as a pair of adjustment nuts 14. It may be fixed to the tube 5. Further, as shown in FIG. 3, the cylindrical adjusting tube 5 includes a pair of tightening nuts 15 sandwiched from both sides by the steady spacer 16, and the fixing bolt 4 is attached to the cylindrical portion 10 by the pair of tightening nuts 15. It may be fixed.

  Here, a method for adjusting the insertion level of the fixing bolt 4 by the amount of penetration of the cylindrical adjusting tube 5 into the inclined surface 13 will be described. In this embodiment, the adjustment nut 14 provided on the connection member 17 side of the second through hole 7b is fixed to the bottom plate portion 11 by, for example, welding. Accordingly, when the cylindrical adjustment tube 5 is rotated, the adjustment nut 14 is rotated, and the cylindrical adjustment tube 5 is moved with respect to the fixing bolt 4. Thereby, the amount of penetration of the cylindrical adjustment tube 5 into the ground is adjusted, and the insertion level of the cylindrical adjustment tube 5 can be adjusted. In another embodiment, the adjusting nut 14 is freely rotated without being fixed to the bottom plate portion 11, and the adjusting nut 14 provided on the inner side of the second through hole 7b is moved from the grout inlet 9 described later to the outer side. The amount of penetration of the cylindrical adjustment pipe 5 into the ground may be adjusted by rotating in the same manner as the adjustment nut 14. As described above, the cylindrical adjusting tube 5 can adjust the amount of penetration into the inclined surface 13 by pushing and pulling the cylindrical portion 10, but the fixing bolt 4 is connected to the second through hole 7 b of the bottom plate portion 11. A more delicate amount can be adjusted by rotating the adjusting nut 14 to be engaged.

  Further, a grout inlet 9 is provided on the cylindrical adjustment tube 5, that is, the wall surface of the cylindrical portion 10 or the plate surface of the bottom plate portion 11, and the inside of the hole 6 into which the fixing bolt 4 is inserted and to the inclined surface 13. The grout 8 is injected from the grout injection port 9 into the inside of the cylindrical adjustment tube 5 that has penetrated. Here, the grout injected into the bore 6 is referred to as a bore internal grout 8a, and the grout injected into the cylindrical adjustment tube 5 is referred to as a tubular adjustment tube internal grout 8b. The fixing bolt 4 exposed to the ground is reinforced by the cylindrical adjusting tube internal grout 8b injected into the cylindrical adjusting tube 5 in this way. Further, the inside of the hole 6 is obtained by continuously injecting the inside grout 8a of the hole to be injected into the inside of the hole 6 and the inside of the cylindrical adjusting pipe 8b to be injected into the inside of the cylindrical adjusting pipe 5. And the inside of the cylindrical adjustment pipe 5 are integrally reinforced. Furthermore, when the photovoltaic power generation panel 2 receives a blowing force by wind, it can be resisted by being mainly suppressed by the peripheral frictional resistance between the drilled inner grout 8a and the natural ground.

  FIG. 4 shows details of the insertion angle adjusting means 12. 4 (a) and 4 (b) show details of a spherical washer 12a and a spherical nut 12b which are one embodiment of the insertion angle adjusting means 12. FIG. FIG. 4C shows the details of the connection among the fixing bolt 4, the connection member 17, and the panel support frame 3. As shown in FIGS. 2 and 4, the insertion angle adjusting means 12 fixes the fixing bolt 4 penetrating the panel support frame 3 by a pair of spherical washers 12a and spherical nuts 12b facing each other from both sides of the connection member 17. The connection angle of the connection member 17 with respect to the bolt 4 is rotated and adjusted. Since the spherical washer 12a and the spherical nut 12b have spherical surfaces with the same curvature, the spherical washer 12a and the spherical nut 12b can be easily rotated to adjust the connection angle of the connecting member 17 to the fixing bolt 4. The insertion angle of the fixing bolt 4 is adjusted by the rotation angle between the spherical nuts 12b.

  The construction error of the fixing bolt 4 provided on the inclined surface 13 will be described with reference to FIG. The installation accuracy of the photovoltaic power generation panel 2 is closely related to the installation accuracy of the fixing bolt 4. That is, when the construction accuracy of the fixing bolt 4 is extremely poor, a situation occurs in which the photovoltaic power generation panel 2 itself cannot be attached. Moreover, when the construction accuracy of the fixing bolt 4 is poor, the installation angle of the panel surface of the photovoltaic power generation panel 2 is disturbed, and the power generation capacity of the photovoltaic power generation panel 2 is reduced. In these cases, for example, it is necessary to take measures such as redoing the fixing bolt 4 or repairing the panel support frame 3 so as to absorb the fixing accuracy of the fixing bolt 4.

  In the installation of installing the fixing bolt 4 on the inclined surface 13, there are mainly three construction errors. The first construction error is a construction error related to the installation position of the fixing bolt 4. That is, it is an error in the coordinate position after construction with respect to the designed coordinate position where the fixing bolt 4 is to be inserted in the hole 6 provided in the inclined surface 13. The second construction error is a construction error related to the amount of penetration of the cylindrical adjustment pipe 5. That is, this is an error in the height position after construction with respect to the designed height position in which the cylindrical adjustment pipe 5 should be penetrated in the hole 6 provided in the inclined surface 13. Furthermore, the third construction error is a construction error related to the insertion angle of the fixing bolt 4. In other words, this is an error in the verticality after construction with respect to the designed verticality in which the fixing bolt 4 should be inserted in the drilling hole 6 provided in the inclined surface 13.

  As shown in FIG. 5, in the inclined surface 13, the inclined line (L) which becomes the reference of the inclined surface 13, the moving inclined line (M) moved horizontally from the inclined line (L) by the distance (d), and the inclined line ( L) and a vertical line (N) of the fixing bolt 4 orthogonal to the moving inclination line (M) are set. A point P that is an intersection of the inclined line (L) and the vertical line (N) is a point where the fixing bolt 4 is installed. Further, a point Q that is an intersection of the moving inclination line (M) and the vertical line (N) is an intersection of the fixing bolt 4 and the connection member 17 of the panel support frame 3.

  The first construction error related to the installation position of the fixing bolt 4 will be described. The point P at which the fixing bolt 4 is installed on the inclined surface 13 is determined by measuring the coordinate position in a grid pattern on the inclined surface 13 by surveying. Although a construction error also occurs at the position of the point P, the grout 8 is injected into the hole 6 provided in the inclined surface 13 after the fixing bolt 4 is inserted as described above. Therefore, it is possible to correct the insertion position of the fixing bolt 4 after the injection of the grout 8.

  Next, the penetration amount of the cylindrical adjustment pipe 5 which is the second construction error will be described. In FIG. 5, the position of the cylindrical adjustment tube 5 is the point P, which is the intersection of the inclined line (L) and the vertical line (N), or the intersection of the moving inclined line (M) and the vertical line (N). Although the Q point is the reference, there is a possibility that an error that goes up and down in the direction of the vertical line (N) occurs after construction. Due to this construction error, the photovoltaic power generation panel 2 cannot be attached. Or the level of the connection member 17 of the panel support frame 3 varies, and the installation angle of the panel surface of the photovoltaic power generation panel 2 is disturbed. This construction error can be easily adjusted by the amount of penetration of the cylindrical portion 10 of the cylindrical adjustment tube 5.

  Furthermore, the insertion angle of the fixing bolt 4 that is the third construction error will be described. In FIG. 5, the insertion angle of the cylindrical adjustment tube 5 may be inclined at an inclination angle (α) with the Q point that is the intersection of the moving inclination line (M) and the vertical line (N) as the center of rotation. There is a possibility that an error in the vertical line (N) direction occurs after the construction. Due to this construction error, the photovoltaic power generation panel 2 cannot be attached. Or the position of the connection member 17 of the panel support frame 3 is shifted, and the installation angle of the panel surface of the photovoltaic power generation panel 2 is disturbed. This construction error can be easily adjusted by the insertion angle adjusting means 12 at the point Q.

  First, the fixing bolt 4 is inserted into the hole 6 provided on the inclined surface 13 (S1). The construction method of the fixing bolt 4 shown in this step is selected according to construction conditions such as the ground layer of the inclined surface 13. For example, the hole 6 may be provided in the inclined surface 13 and the fixing bolt 4 may be inserted into the hole 6, or a bit for the hole 6 may be attached to the tip of the fixing bolt 4 to form the inclined surface 13. The fixing bolt 4 may be inserted while drilling. The point where the fixing bolt 4 is inserted into the inclined surface 13 is previously determined by surveying. The fixing bolt 4 is inserted in a direction substantially orthogonal to the virtual inclination angle of the inclined surface 13.

  Next, the fixing bolt 4 is passed through the second through-hole 7b provided in the bottom plate portion 11 of the cylindrical adjustment tube 5, and the opening end 20 of the cylindrical adjustment tube 5 is inserted into the inclined surface 13 (S2). At this time, the amount of penetration of the cylindrical adjustment pipe 5 into the inclined surface 13 is adjusted (S3). The amount of penetration is adjusted by pushing and pulling the tubular portion 10 or rotating the adjustment nut 14. Next, the panel support frame 3 that supports the photovoltaic power generation panel 2 is connected to the fixing bolt 4 (S4). That is, the fixing bolt 4 is connected to the connecting member 17 by a pair of spherical washers 12a and a spherical nut 12b, which is one embodiment of the insertion angle adjusting means for sandwiching the connecting member 17 in the first through hole 7a provided in the connecting member 17.

  Grout is injected from the grout inlet 9 provided in the cylindrical adjustment pipe 5 into the hole 6 where the fixing bolt 4 is inserted and into the cylindrical adjustment pipe 5 inserted into the inclined surface 13. The grout injection may be performed in two stages, the inside of the drilling hole 6 and the inside of the cylindrical adjustment tube 5. Alternatively, grout may be injected into the hole 6 in advance, and the fixing bolt 4 may be inserted thereafter. Alternatively, it may be performed after the panel support frame 3 and the fixing bolt 4 are connected.

  In each step described above, it is determined whether or not the photovoltaic power generation panel 2 can be connected to the panel support frame 3, and if there is no problem, the process proceeds to the next step, and if there is a problem, the process returns to S3 or S5. Then, the amount of penetration of the cylindrical adjustment tube 5 into the inclined surface 13 is adjusted (S3), or the connection angle between the panel support frame 3 and the fixing bolt 4 is adjusted (S5). Further, it is determined whether or not the panel surface of the photovoltaic power generation panel 2 is disturbed. If there is no problem, the process proceeds to the next step. If there is a problem, the process returns to S3 or S5 again to the inclined surface 13. The amount of penetration of the cylindrical adjustment tube 5 is adjusted (S3), or the connection angle between the panel support frame 3 and the fixing bolt 4 is adjusted (S5).

  In the installation method of the photovoltaic power generation panel 2, the penetration amount adjusting means in S3 specifically has the following contents. That is, the amount of penetration of the cylindrical adjustment pipe 5 into the ground is adjusted by rotating the adjustment nut 14 that engages with the fixing bolt 4 in the second through hole 7b of the bottom plate portion 11. Thereby, the position and inclination of the installation surface of the photovoltaic power generation panel 2 are adjusted. Alternatively, the adjustment nut 14 provided on the connection member 17 side of the second through hole 7b of the bottom plate portion 11 is fixed to the bottom plate portion 11 and the cylindrical adjustment tube 5 is rotated to rotate the cylindrical adjustment tube 5 to the ground. Adjust the amount of penetration.

  Moreover, in the installation method of this photovoltaic power generation panel 2, the insertion angle adjustment means of S5 is specifically as follows. That is, the panel support frame 3 and the fixing bolt 4 are connected via the connection member 17. The mounting angle of the connecting member 17 with respect to the fixing bolt 4 is set by a pair of spherical washers 12a and a spherical nut 12b, which is one embodiment of the insertion angle adjusting means for sandwiching the connecting member 17 from both side surfaces of the connecting member 17. Rotate to adjust. Thereby, the position and inclination of the installation surface of the photovoltaic power generation panel 2 are adjusted.
