Description

  The present invention allows a solar panel to be supported on a structure such as a roof (mainly a flat roof), a roof of a building, and a ground surface (including a ground surface, a flat surface with substantially no inclination provided with concrete on the ground), and the like. The present invention relates to a solar cell panel support structure and a solar cell panel support method.

  By installing solar cell panels of the solar power generation system on structures such as roofs (including flat roofs), rooftops of buildings, and the ground surface, it is possible to generate power efficiently with solar cells. And as an example of how to install solar panels on such a structure, conventionally, a foundation such as concrete or brick is installed on the structure, and a platform made of aluminum or iron is installed on the foundation And the method of installing a solar cell panel on the mount is performed. According to such a method, the solar cell panel can be firmly installed on the structure so that the solar cell panel is not blown away by wind or the like.

  However, in the above conventional installation method, it is necessary to provide a foundation on the structure, and it is also necessary to fix the foundation to the structure with an anchor bolt or the like. For this reason, once a solar cell panel is installed in a structure, it is difficult to change the installation location and orientation of the solar cell panel later. In order to improve wind pressure resistance, for example, when a concrete foundation is provided integrally with a structural frame of a building, it is necessary to form the foundation using uncured concrete. Therefore, a curing period for curing the concrete is required. During the curing period, the weight of the concrete is greater than the hardened concrete. For this reason, when the load resistance of a building is small, it is also considered that a solar cell panel cannot be installed in a structure.

  Further, when the concrete foundation is provided integrally with the structural frame of the building, it is necessary to remove the waterproof layer provided on the structural frame once. For this reason, it is conceivable that rain leakage or the like may occur in the building during the construction period. In view of this, a method for installing a solar cell panel without installing a foundation such as concrete has been proposed (see Patent Documents 1 and 2).

  However, also in the conventional installation method, the gantry is attached to the structure by anchor bolts, for example. For this reason, for example, if it is a roof of a house, it is necessary to drive anchor bolts into the concrete layer of the roof. It may also cause In particular, even on small flat surfaces such as flat roofs and building roofs, even small cracks can cause the entire structure to leak. And even if a rain leak occurs, it is often difficult to elucidate the location that causes it.

  For this reason, the installation method of the solar cell panel which can fix a mount frame to a roof, without using an anchor bolt etc. is calculated | required. In order to meet such a demand, for example, in Patent Document 3, a solar cell panel is fixed to a structure such as a roof by a load due to a concrete block and the weight of the solar cell panel.

Japanese Patent Laid-Open No. 2006-210613 JP 2012-104756 A Registered Utility Model No. 3164142

  In Patent Document 3, a rectangular solar cell panel is supported by, for example, support members disposed at four points in the vicinity of four corners, and each support member is fixed by a heavy load such as a concrete block. For this reason, it is necessary to move each supporting member to an appropriate position by moving a heavy concrete block.

  However, solar cell panels are often provided inclined with respect to the horizontal direction in order to increase the amount of sunlight received. And in order to incline a solar cell panel by a desired angle, it is necessary to arrange | position two support members from which height differs at an appropriate space | interval. Further, in order to prevent the solar cell panel from tilting in a direction different from the direction that should originally be tilted (for example, the north-south direction), the center lines of the pair of support members are arranged in a straight line, for example, in the north-south direction. There is a need.

  In many cases, the solar cell panel is installed at a high place such as a roof or a roof of a building. In such a case, the solar cell panel may be beaten by a strong wind during the installation. In such an environment, the work of moving the heavy concrete block with a small number of people and installing the support members at the appropriate intervals and in a straight line as described above is actually very difficult. In many cases, the work is difficult. As a result, the intervals between the support members may not be appropriate, or the center lines of the support members may not be aligned, and the designed strength may not be obtained. And when the inclination angle of an actual solar cell panel is not as designed, it is possible that the power generation performance of a solar cell falls.

  The present invention has been made in order to solve the above-described problems, and includes a solar cell panel support structure (including a continuous structure) in which the solar cell panel can be easily installed with a highly accurate position and posture. ) And a support method.

Each includes a first unit and a second unit including the first support member, the second support member and the connecting member,
The present invention relates to a continuous structure of solar cell panels in which the first unit and the second unit are connected by the weight mounting portion.

Still another aspect of the present invention provides a method for supporting a solar cell panel on a structure by at least one support base through at least a first portion of the solar cell panel and a second portion facing the first portion. Because
The support base is a plate-like first support member having at one end a first connection portion connected to the first portion, and a plate-like shape having a second connection portion connected to the second portion at one end portion.

  The present invention relates to a support structure in which a solar cell panel is supported on a structure by at least a first portion of the solar cell panel and a second portion facing the first portion. The support structure for the solar cell panel of the present invention is not limited to the support structure for supporting the solar cell panel at two locations, but can of course be applied to a support structure for supporting the solar cell panel at three or more locations.

  The 1st part of a solar cell panel is supported by the plate-shaped 1st support member which has the 1st connection part connected to this at one end part. The second portion facing the first portion of the solar cell panel is supported by a plate-like second support member having a second connection portion connected to the second portion at one end. The first support member is fixed to the structure by the load of the first weight, and the second support member is fixed to the structure by the load of the second weight. The weights of the first weight and the second weight are the weight of the solar cell panel, the weight of all weights including the first weight and the second weight, without the need for anchor bolts or the like, 1 The weight of each member such as a support member is set to a weight capable of fixing the solar cell panel to the structure with sufficient strength. The upper limit of the weight can be determined in consideration of the load resistance of the structure and the ease of installation work.

  And the support structure of this invention is equipped with the plate-shaped connection member which connects the other end part of a 1st support member, and the other end part of a 2nd support member. As a result, it becomes easy to install a plurality of support members on the structure at the designed intervals and postures, and the solar cell panel is attached to the structure at the designed positions and postures (inclination and the direction of the inclination). Becomes easy. As a result, it becomes easy to install the solar cell panel on the structure with a desired strength, and the photovoltaic power generation system including the solar cell panel can exhibit the power generation performance as designed. Furthermore, since there is no need to install a concrete foundation or to drive anchor bolts into the roof of a building, for example, it is possible to solve problems such as damage to the roof and leakage of rain.

  Further, as is apparent from the above description, the one set of the first support member, the second support member, and the connection member may be one of the constituent elements that constitute the mount on which the solar cell panel is attached. Therefore, one set of the first support member, the second support member, and the connecting member is referred to as a “unit” in this specification. And the stand (support stand) which supports one solar cell panel can be comprised with a plurality of units, typically two units.

  In one form of this invention, the 1st connection part has the 1st engagement part engaged with the 1st part of a solar cell panel, and the 2nd connection where a 2nd connection part engages with a 2nd part. Has a joint. Then, the first engaging portion and the second engaging portion are respectively maintained in the engaged state with the first portion and the second portion by the elastic force exerted by the first supporting member and the second supporting member. Are biased in opposite directions.

  In the above-described configuration, one end of each of the two support members is engaged with a solar cell panel (more specifically, a solar cell panel frame or the like) at two different locations of the solar cell panel. And the other end part of each support member is connected to the connection member, and is being fixed. For this reason, for example, it becomes possible to make each support member exhibit the elastic force opposite to the bent direction by bending each support member in the opposite direction. It is possible to increase the connection strength between each support member and the solar cell panel by engaging the engagement portions of the two support members with the solar cell panel against such elastic force. . Thereby, the installation intensity | strength of a solar cell panel can be improved.

  Or when performing the operation | work which fixes a solar cell panel to a supporting member with a volt | bolt, for example, it also becomes possible to temporarily fix a solar cell panel to each supporting member with said elastic force. As a result, for example, it is possible to easily perform work by one person, and it is possible to reduce the number of people required for the attachment work and to reduce the time required for the attachment work. Therefore, the installation cost of a solar cell panel can be reduced.

  As a more specific form using the above-mentioned elastic force, for example, a form in which the connecting member is horizontally placed and the first support member and the second support member are vertically upward at both ends thereof to support the solar cell panel. Can be considered. In such a case, as shown by a solid line in FIG. 4, the first support member and the second support member are inclined in a direction in which the upper end portions are separated from each other, for example, in an “inverted C shape”. Attach to the connecting member at an angle α different. Alternatively, the first supporting member and the second supporting member are formed at both ends of the connecting member by bending a single long and narrow metal plate so as to achieve such a state.

  And in the state which applied force so that each support member and a connection member may become perpendicular | vertical, the front-end | tip part (engagement part) of each support member is engaged with the flame | frame etc. of a solar cell panel. Thereby, it becomes possible to maintain the engagement state of each support member and the solar cell panel by the elastic force in a state where each support member stands vertically upward. The angle α can be appropriately set depending on the material of each support member and the required mounting strength. From the viewpoint of reducing the distortion generated in each member, the angle is preferably 10 ° or less. Note that the direction in which the first support member and the second support member are inclined from the vertically upward direction is not limited to the above-described “inverted C-shaped” direction, and the first support member and the second support member may be “C-shaped. Can be tilted in the direction in which the upper ends approach each other.

  And in order to exhibit the above elastic forces effectively, it is preferable that the 1st support member, the 2nd support member, and the connection member are integrally formed. For example, it is preferable to form a first support member, a second support member, and a connecting member by bending a single thin metal plate. Thereby, the number of parts when manufacturing the battery panel mount can be reduced, and the manufacturing cost can be reduced. Moreover, by forming integrally, the intensity | strength of the connection part of each member can be improved, and it can prevent that a connection part deform | transforms with time.

  As one form, a 1st weight can be set | placed on a connection member so that it may contact the 1st support member, or may be located in the vicinity. Similarly, the second weight can be placed on the connecting member so as to be in contact with or in the vicinity of the second support member. Accordingly, there is no need to provide another weight placing portion, and it is easy to reduce the size of the gantry. And simultaneously with fixing a 1st support member and a 2nd support member with a weight load, a connection member can also be firmly fixed to a structure firmly.

  As another form, the first weight is placed on the connecting member so as to be in contact with or near the first support member, and the second weight is the first support member of the second support member. Can be placed on a weight mounting portion provided so as to be in contact with the opposite portion. In this configuration, the bottom area of the unit is increased by attaching the weight mounting portion to the second support member so as to be in contact with the structure. Therefore, since the stability of the unit increases, the solar cell panel can be supported more stably. In addition, when a plurality of solar cell panels are arranged in a structure with a similar support structure, the weight mounting portion should be used as a connection member for connecting one unit to another unit. You can also. As a result, since it becomes easy to determine the positional relationship of each unit correctly, it becomes easy to install a plurality of solar battery panels in an orderly manner on one structure.

  Moreover, the 1st part and 2nd part of a solar cell panel can be made into different height by changing and installing the height of a 1st connection part and a 2nd connection part. Thereby, a solar cell panel can be inclined with respect to a horizontal direction so that the light reception amount of a solar cell panel may be enlarged.

  The first connection portion can be formed by bending one end portion (upper end portion) of the first support member toward the second support member. Further, the second connection portion can be formed by bending one end portion (upper end portion) of the second support member toward the first support member. At this time, the solar cell panel is more stably formed by bending the first connection portion and the second connection portion at an angle that is parallel to the solar cell panel, so that the first support member and the second support member are more stable. Can be connected to. As a result, the installation strength of the solar cell panel can be improved, the solar cell panel can be stably installed, and the installation work can be simplified.

  Here, the plate-like first support member and second support member can be reinforced by bending so that at least a part of each side end portion is raised. The reinforcing portion thus formed is a portion of the first support member and the second support member excluding the first connection portion and the second connection portion (typically, a portion of each support member standing vertically) (Hereinafter, also referred to as a support portion main body) or at least a part of the first connection portion and the second connection portion. In addition, the “side end portion” of the first support member and the second support member refers to an end portion along the direction (typically the vertical direction) in which a load is applied in the case of the support portion main body. If it is a 1st connection part and a 2nd connection part, the edge part in the edge | side continuous with the side edge part of a support part main body will be said. Hereinafter, the reinforcement part formed in the support part main body is called a 1st reinforcement part, and the reinforcement part formed in the 1st connection part and the 2nd connection part is called a 2nd reinforcement part.

  Further, a reinforcing portion (third reinforcing portion) can be formed on the connecting member in the same manner as described above. For example, when the connecting member is rectangular and is connected to the other end portions of the first support member and the second support member at the end portions along the two short sides, the end portions along the two long sides The third reinforcing portion can be formed by bending so that at least a part of the portion is raised.

  By forming the reinforcing portion as described above, the strength of the unit can be improved, and the support strength of the solar cell panel can be easily improved. Moreover, since the shape as each member and the whole unit is stabilized by providing a reinforcement part, handling becomes easy. Therefore, the installation work of the solar cell panel is simplified. As a result, work personnel and work time can be reduced, and the installation cost of the solar cell panel can be reduced.

  By providing the third reinforcing portion in a portion that is 2/3 or more of the entire length of the connecting member, the shape of the unit can be sufficiently stabilized. Therefore, the third reinforcing portion is not provided in the portion adjacent to the first support member of the connecting member, and the size of the non-reinforcing portion is set to fit with the first weight, so that the first weight is set. Can be easily positioned so that it does not move freely after installation. In addition, since the contact area between the first weight and the main body portion excluding the reinforcing portion of the connecting member can be increased, the solar cell panel can be supported more stably. The same applies to the second weight.

  And the angle which a 1st connection part and a 2nd connection part and a support member main body make can be stabilized by mutually connecting the opposing end part of a 1st reinforcement part and a 2nd reinforcement part by welding, for example. . Thereby, a solar cell panel can be supported stably. Furthermore, when the 1st connection part and the 2nd connection part, and the solar cell panel are made parallel, the effect of the support strength improvement can also be exhibited reliably.

  In addition, at least one of the first support part and the first connection part, and the second support part and the second connection part may be coupled by a reinforcing material (first reinforcing material, second reinforcing material), or the first supporting member, 2 The shape of the unit can be further stabilized by coupling at least one of the support member, the first connection portion, and the second connection portion with a connecting member and a reinforcing material (third reinforcing material). Thereby, the installation intensity | strength of a solar cell panel can be improved.

  By placing the cushion material below at least one of the first weight and the second weight, it is possible to prevent the connecting member and the weight placing portion from directly contacting the structure with a large pressure. Thereby, it can prevent that the surface of a structure is damaged. In addition, by placing a cushion material, the weight load can be evenly distributed without being partially offset. Furthermore, the adhesion between the portion where the weight is placed and the structure is improved, and stable installation can be achieved. And in order to exhibit such an effect to the maximum, it is preferable to arrange | position a cushion material so that all may overlap with the bottom face shape of a weight. For example, if the weight has a rectangular parallelepiped shape, its bottom surface is rectangular, and its long side is larger than the width of the connecting member, the weight protrudes from the connecting member. By disposing the cushion material including the protruding portion so as to be positioned below the weight, it is possible to obtain an effect of preventing damage to the surface of the structure more completely.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
(Embodiment 1)
In FIG. 1, the support structure of the solar cell panel which concerns on one Embodiment of this invention is shown with a top view. FIG. 2 is a partial cross-sectional view of the support structure as viewed from the front.

  The support structure 10 in the illustrated example includes, for example, a rectangular solar cell panel 12, a rooftop of a building, a roof of a house (mainly a flat roof), or a ground surface (including a flat surface on which the ground and concrete are exposed). 1 or more (for example, two) units 14 that are components of the mount of the solar battery panel 12 and the unit 14 according to the weight thereof. A plurality of weights (first weight 11 and second weight 13) provided for each unit 14 are included so as to be fixed to the structure. The first weight 11 and the second weight 13 can be formed from, for example, a rectangular parallelepiped concrete block.

  The unit 14 includes an elongated base plate (connecting member) 16, a first vertical plate (first support member) 18, and a second vertical plate (second support member) 20 having a rectangular shape. The base plate 16 can be installed horizontally on the structure. The first vertical plate 18 supports the first portion 12a of the solar cell panel 12 at the upper end. The second vertical plate 20 supports the second portion 12b of the solar cell panel 12 at the upper end.

  The solar cell panel 12 includes a plate-like solar cell module 30 formed by providing solar cell elements in a predetermined arrangement on one or more substrates made of a glass substrate, a flexible substrate, and the like, and an outer peripheral portion of the solar cell module 30. Frame 32 to be attached.

  As described above, the unit 14 supports the solar cell panel 12 in two parts (a first part 12a and a second part 12b). In which part of the solar cell panel 12 the first part 12a and the second part 12b are arranged is not particularly limited. In the support structure 10 of the illustrated example, the first portion 12a and the second portion are arranged at opposite portions of the end portions (hereinafter referred to as long-side end portions) EL1 and EL2 along the two long sides of the rectangular solar cell panel 12. The part 12b is arranged. The first portion 12a is preferably supported by the first vertical plate 18 at a position higher than the second portion 12b. Thereby, the solar cell panel 12 can be inclined with respect to the horizontal direction, for example, in the north-south direction, and the amount of light received by the solar cell panel 12 can be increased to generate power more efficiently.

  The base plate 16 may have an elongated shape such as a rectangle. If the base plate 16 is rectangular, the first vertical plate 18 and the second vertical plate 20 have two end portions in the longitudinal direction of the base plate 16 (hereinafter also referred to as short side end portions). ) Respectively. The base plate 16, the first vertical plate 18, and the second vertical plate 20 can be formed from, for example, one elongated metal plate. The material of the metal plate can be stainless steel, anodized aluminum, or the like.

  When the base plate 16 is installed horizontally on the structure, the first vertical plate 18 and the second vertical plate 20 can be vertically attached to the base plate 16. Alternatively, even when the base plate 16 is installed horizontally on the structure, as schematically shown in FIG. 4, the first vertical plate 18 and the second vertical plate 20 have an angle θ <b> 1 with the base plate 16. And θ2 may be connected to the base plate 16 so that (90 + α) ° or (90−α) °. In this case, the angle α is preferably larger than 0 ° and not larger than 10 °. More preferably, the angle α is greater than 0 ° and 5 ° or less.

  The first weight 11 can be placed on the base plate 16 so as to be in contact with the first vertical plate 18 or in the vicinity thereof. Thereby, the first vertical plate 18 can be fixed to the structure by the weight of the first weight 11. Similarly, the second weight 13 can be placed on the base plate 16 so as to be in contact with or in the vicinity of the second vertical plate 20. Thereby, the second vertical plate 20 can be fixed to the structure by the weight of the second weight 13. The base plate 16 can be fixed to the structure by the weights of the first weight 11 and the second weight 13. If the first weight 11 is a cubic shape, the bottom surface is rectangular, and the length of the long side can be made larger than the width of the base plate 16. The same applies to the second weight 13.

  As shown to FIG. 3A, the 1st vertical board 18 contains the support part main body 22 and the 1st connection part 24 to which the solar cell panel 12 is connected. On the other hand, the 2nd vertical board 20 contains the support part main body 26 and the 2nd connection part 28 to which the solar cell panel 12 is connected. The outer peripheral part of the solar cell panel 12 or the frame 32 is fixed to the first connecting part 24 and the second connecting part 28 with a pressing metal fitting 34 or the like.

  FIG. 5 is an enlarged perspective view showing an example of the holding metal fitting. In FIG. 6, the fixing structure of the solar cell panel by the pressing metal fitting is enlarged and shown in a sectional view. The holding metal fitting 34 in the illustrated example has a plate-like lower portion 34c fixed to the first connection portion 24 or the second connection portion 28 by, for example, a bolt 34a and a nut 34b, and a plate-like shape rising vertically from one end portion of the lower portion 34c. The middle portion 34d includes an upper portion 34e that is connected to the upper end portion of the middle portion 34d and presses the frame 32 toward the first connection portion 24 and the second connection portion 28.

  The 1st connection part 24 and the 2nd connection part 28 can be formed from the plate-shaped member parallel to the solar cell panel 12 or the solar cell module 30. FIG. Thereby, it becomes easy to increase the contact area between the outer peripheral part of the solar cell panel 12 or the frame 32 and the first connection part 24 and the second connection part 28. As a result, the outer peripheral portion of the solar cell panel 12 or the frame 32 can be stably fixed to the first connection portion 24 and the second connection portion 28 by the presser fitting 34.

  Furthermore, the 1st connection part 24 can form the 1st engaging part 36 engaged with the outer peripheral part of the solar cell panel 12, or the flame | frame 32. As shown in FIG. Similarly, a second engagement portion 38 that engages with the outer peripheral portion of the solar cell panel 12 or the frame 32 can be formed in the second connection portion 28. The first engaging portion 36 and the second engaging portion 38 can be formed, for example, by bending the respective distal end portions of the first connecting portion 24 and the second connecting portion 28 upward.

  And the 1st engaging part 36 and the 2nd engaging part 38 are the outer periphery of the solar cell panel 12 when the angle of the 1st vertical board 18 and the 2nd vertical board 20, and the base plate 16 becomes 90 degrees. Or can be formed to engage the frame 32. At this time, for example, by forming the first vertical plate 18 and the second vertical plate 20 so that the angles θ1 and θ2 with the base plate 16 are (90 + α) ° (see FIG. 4), the first engagement In a state where the portion 36 and the second engagement portion 38 are engaged with the outer peripheral portion of the solar cell panel 12 or the frame 32, the elastic force F1 toward the outside is generated in the first vertical plate 18 and the second vertical plate 20. ing. In the following description, for the sake of convenience, the direction in which the angles θ1 and θ2 are increased is referred to as “outside”, and the direction in which the angles θ1 and θ2 are increased is referred to as “inside”.

  As a result, it becomes easy to stably maintain the engagement state between the first engagement portion 36 and the second engagement portion 38 and the outer peripheral portion of the solar cell panel 12 or the frame 32, thereby supporting the solar cell panel 12. Strength can be improved. Furthermore, when the solar cell panel 12 is fixed to the first connection part 24 and the second connection part 28 by the presser bracket 34, for example, an operator other than an operator who performs bolting needs to support the solar cell panel 12. Therefore, the number of workers and the work time can be shortened. Therefore, the installation cost of the solar cell panel 12 can be reduced. Further, by attaching the first vertical plate 18 and the second vertical plate 20 to the base plate 16 so that the angles θ1 and θ2 with the base plate 16 are (90−α) °, the first vertical plate 18 and the second vertical plate 20 are in a direction opposite to the elastic force F1. The case where the same effect is obtained by exerting the elastic force is also included in the present invention.

  Furthermore, if the base plate 16 is a rectangle, the reinforcement part 16a can be provided in at least one part of the edge part along the long side. That is, the reinforcing portion 16a can be provided on at least a part of both end portions in the width direction of the base plate 16 (hereinafter referred to as long side end portions). The reinforcing portion 16a can be formed by bending the long side end portion of the base plate 16 so as to rise by a predetermined width (for example, 5 to 20 mm). The reinforcing portion 16a should not be provided on a portion of the base plate 16 where the first weight 11 and the second weight 13 are placed (portions in the vicinity of the first vertical plate 18 and the second vertical plate 20). Can do. That is, the non-installation part of the reinforcement part 16a can be provided in the both ends of the base plate 16 in the longitudinal direction. Thereby, the 1st weight 11 and the 2nd weight 13, and the main-body part of the baseplate 16 can be made to contact directly, and it becomes easy to enlarge a contact area.
