Description

  The present invention relates to a solar cell panel support structure in which a solar cell panel is supported on an attachment object such as a roof of a building.

  In recent years, energy problems such as power shortage have been widely taken up by the mass media and the like, and power generation using natural energy has attracted attention. Solar cells are expected to contribute to solving such energy problems because they can generate power without causing harmful effects such as air pollution. For this reason, solar cells have become widespread not only as industrial mega solar systems installed on a vast land, but also as household power sources installed on the roofs of households.

  As a support structure for forming a solar cell on a glass substrate, protecting the surface with a film, and supporting the solar cell panel formed by holding it with a frame member (frame) on an attachment object such as a roof, For example, what was disclosed by patent documents 1-3 is known. The support structure of the solar cell panel described in Patent Document 1 fixes the solar cell panel by providing a protrusion at the lower part of the frame, hooking a metal fitting on the protrusion, and fixing the metal fitting to an attachment object. In the support structure of Patent Document 2, the solar cell panel is fixed by tightening the frame from above with the bolts and nuts at the edges of the metal fittings having a hat-shaped cross section. Similarly, in the support structure of Patent Document 3, the solar cell panel is fixed by tightening the frame from above with pressing bolts and nuts at the edge of a shallow hat-shaped metal fitting.

  However, in the support structure of Patent Document 1, it is necessary to form a protrusion on the lower part of the frame of the solar cell panel, and the shape of the frame is limited. For this reason, it is necessary to manufacture a frame having such a shape, not a general-purpose frame. Therefore, the manufacturing cost of the solar cell panel increases. Moreover, since the load for fixing the solar cell panel is concentrated only on the protrusion, it is difficult to fix the solar cell firmly and stably.

  On the other hand, in the support structures of Patent Documents 2 and 3, in order to press and fix the frame of the solar cell panel from above, the solar cell panel having variously shaped frames can be fixed to the attachment object. . In addition, since the frame is entirely pressed and fixed, the load is dispersed and the solar cell panel can be firmly fixed. However, in the support structures of Patent Documents 2 and 3, since the mounting bracket is fixed simply using bolts and hex nuts, the bolts and hex nuts and the brackets eventually come into contact with each other relatively. The load is concentrated in a small area, and it is difficult to stably fix the solar cell panel.

Therefore, the present invention provides a solar cell panel including a solar cell and a frame by a pair of support units fixed to an attachment object at a first portion of the frame and a second portion facing the first portion, respectively.

  In the present invention, a solar cell panel including a solar cell and a frame is supported by a pair of support units fixed to an attachment object at a first portion of the frame and a second portion facing the first portion, respectively. The present invention relates to a support structure for a solar cell panel that fixes the solar cell panel to an attachment object. The attachment object is typically a roof of a building, particularly a slope of the roof, but is not limited thereto. If an appropriate mount is installed, the attachment object may be a ground where concrete is exposed or a bare ground. The shape of the solar cell panel is not particularly limited as long as the shape has opposing sides. However, a rectangular solar cell panel is typical, and if it is a rectangle, the first part and the second part can be provided on a pair of opposite sides of the rectangle, respectively. In that case, the first part and the second part do not need to face each other. For example, the first part may be provided at the center of one side and the second part may be provided near the corner of the opposite side. Good.

  The support unit includes a lower member, an upper member, an intermediate member, a pressing member, and a pair of first fastening members and second fastening members. The lower member includes a first bottom portion, two first side portions that rise from a pair of sides of the first bottom portion, and two lip portions that are connected to the respective upper end portions of the first side portion. It is a lip channel steel member that is fixed to an attachment object with the lip portion facing up. The upper member has a rectangular second bottom, two second sides that rise from a pair of sides of the second bottom, and a bent portion that is connected to at least one upper end of the two second sides. And it is a shaped steel-like member arrange | positioned on a lower member with a 2nd bottom part facing down.

  The intermediate member is disposed between the lower member and the upper member, and falls from a pair of sides of the rectangular main portion that contacts the two lip portions of the lower member, and the two lower members. It is a channel steel member which has a pair of engaging parts which each engages with the 1st side part. For example, the second bottom portion of the upper member contacts the upper surface of the main portion.

  The holding member has a rectangular top and two third side portions that respectively fall from a pair of sides of the top, and is arranged inside the upper member with the axial direction parallel to the axial direction of the upper member. In addition, it is a channel steel member in which the lower end portions of the two third side portions are in contact with the lower end portions of the two second side portions of the upper member.

  The other pressing member has a rectangular third bottom portion and two third side portions respectively rising from a pair of sides of the third bottom portion, and the axial direction is parallel to the axial direction of the upper member. It is a channel-shaped steel-like member which is arrange | positioned inside and the upper end part of two 3rd side parts contact | abuts with two 2nd side parts of an upper member.

The axial direction is the direction in which the shaped steel extends (the material axial direction), and the axial directions of the second side portion of the upper member and the third side portion of the pressing member are the same direction. The pair of first fastening members and second fastening members are members that fix the upper member to the lower member by being fastened together. Note that the concepts of “upper” and “lower” in the above description indicate the positional relationship when the solar cell panel is attached to the roof of a building so that the light receiving surface of the solar cell is directed upward or obliquely upward. .

  In the support structure of the present invention, the first fastening member is engaged with the pressing member, and the second fastening member is engaged with the two lip portions of the lower member, and thereby the support unit is The solar cell panel is fixed to the attachment object by sandwiching the first portion and the second portion of the frame between the bent portion of the upper member and the lower member.

  As described above, in the present invention, the pressing member having the two third side portions is interposed between the first fastening member (for example, a bolt) to be fastened with the second fastening member and the upper member. And the lower end part or upper end part of two 3rd side parts of a pressing member is contact | abutted with the upper member inside the upper member, and is fixing the upper member to the lower member. Thus, the pressure when the first fastening member and the second fastening member are fastened is not applied only to the peripheral portion of the bolt hole of the first fastening member and the upper member, but to the two third side portions. It will also be distributed to the lower end or upper end. For this reason, compared with the normal structure which fixes an upper member with a volt | bolt via a washer, for example, by adjusting the length (length of an axial direction) of a pressing member, a pressing member and an upper member are adjusted. The contact area can be increased as required. Therefore, it becomes easy to sufficiently disperse the tightening load by the first fastening member (for example, a bolt).

  Moreover, in this invention, the 2nd fastening member (for example, plate-shaped nut) fastened with the 1st fastening member contact | abuts with two lip | rip parts of a lower member, and the upper member is being fixed to the lower member. . As a result, for example, by adjusting the size of the second fastening member, the second fastening member and the lower fastening member can be adjusted by comparing the size of the second fastening member with a normal configuration in which the hexagon nut abuts against the peripheral portion of the bolt hole of the lower member via a washer or the like. The contact area with the member can be increased as necessary, and the tightening load by the second fastening member can be sufficiently dispersed.

  Further, the pair of engaging portions of the intermediate member engage with the two first side portions of the lower member, respectively, and the main portion of the intermediate member presses the two lip portions of the lower member from above. For this reason, it is prevented that the space | interval of the upper end part of two lip parts of a lower member and two 1st side parts will spread by receiving an external force (for example, pulling load of a volt | bolt). Can do. Thereby, for example, even when the solar cell panel is blown by the wind and an external force is applied to pull out the first fastening member that engages with the upper member, the distance between the two lip portions of the lower member is increased. Can be prevented by the intermediate member. As a result, the engagement state between the two lip portions and the second fastening member is released, and the upper member can be prevented from being detached from the lower member. Thereby, a solar cell panel can be stably fixed to an attachment target object.

  Here, when the pressing member has two third side portions that fall from the pair of sides of the top portion, the interval between the outer dimensions of the lower end portions of the two third side portions is the two second side portions of the upper member. It is preferable that it is equal to or larger than the interval between the inner dimensions of the lower end portions of. In addition, when the pressing member has two third side portions that rise from the pair of sides of the third bottom portion, the interval between the outer dimensions of the lower end portions of the two third side portions is the distance between the two second side portions of the upper member. It is preferably equal to or larger than the inner dimension interval. With this configuration, the gap between the two second side portions of the upper member can be increased by the two third side portions of the upper member by inserting the pressing member into the upper member in parallel with the axial direction. It becomes. As a result, the force sandwiching the frame of the solar cell panel can be increased between the bent portion of the upper member and the lower member, and a gap is formed between the second side portion of the upper member and the side surface of the frame. If there is, the gap can be eliminated, or the side surface of the frame can be pressed by the second side portion of the upper member to be firmly fixed between the pair of support units. As a result, the solar cell panel can be more firmly fixed to the attachment object.

  Further, when the pressing member has two third side portions that fall from the pair of sides of the top portion, the interval between the inner dimensions of the upper end portions of the two second side portions of the upper member is the two third side portions of the pressing member. It is preferable that it is larger than the space | interval of the outer dimension of the lower end part of a side part. Thereby, it becomes easy to insert the pressing member into the inside of the upper member, and the attachment work of the solar cell panel to the attachment object can be facilitated. At this time, the outer dimension interval L1 of the lower end portions of the two third side portions of the pressing member (see FIG. 5A), the interval L2 of the lower end portions of the two second side portions of the upper member, and the upper member The relationship between the distances L3 between the upper ends of the two second side portions is preferably L3> L1 ≧ L2, and more preferably L3> L1> L2. Thereby, it is possible to facilitate insertion of the pressing member into the upper member and expansion of the two second side portions of the upper member.

  Further, when the pressing member has two third side portions that rise from the pair of sides of the third bottom portion, the interval between the inner dimensions of the upper ends of the two second side portions of the upper member is the third side portion of the pressing member. It is preferable that it is larger than the space | interval of the outer dimension of the lower end part. Thereby, it becomes easy to insert the pressing member into the inside of the upper member, and the attachment work of the solar cell panel to the attachment object can be facilitated. At this time, the outer dimension interval L1 of the lower ends of the two third side portions of the pressing member, the interval L2 of the lower end portions of the two second side portions of the upper member, and the upper ends of the two second side portions of the upper member The relationship of the part interval L3 is preferably L3> L1 ≧ L2, and more preferably L3> L1> L2. Thereby, it is possible to facilitate insertion of the pressing member into the upper member and expansion of the two second side portions of the upper member.

  Furthermore, it is preferable that the second bottom portion and the second side portion of the upper member are connected by a connection portion having a predetermined radius of curvature R1. Thus, when the pressing member is inserted into the upper member by giving the curvature radius R1 to the connection portion between the second bottom portion and the second side portion of the upper member, the two third sides of the pressing member The distance between the two second side portions of the upper member can be smoothly expanded by the lower end portion of the portion. In addition, by appropriately setting the curvature radius R1, even when the distance between the two second side portions is increased, the strength of the connection portion between the second bottom portion and the second side portion is maintained at a sufficient strength. It becomes easy. From the above viewpoint, the radius of curvature R1 is preferably set to 0.01 to 10 mm.

  In addition, it is desirable that the distance between the two second side portions of the upper member be narrowed to reduce dead space in order to install many solar cell panels. However, since the mounting screw requires a certain strength, the size is required. For this reason, it is necessary to design in consideration of screw strength, workability, and the number of installed solar cell panels.

  Furthermore, the thickness of the third side portion of the pressing member is preferably equal to or greater than the thickness of the second side portion of the upper member. By setting the thickness of the third side portion of the pressing member as described above, when the pressing member is inserted into the upper member, the distance between the two second side portions of the upper member can be easily increased. At the same time, deformation of the pressing member is also suppressed, so that the solar cell panel can be stably attached to the attachment object. Moreover, it is also preferable that the thickness of the top part or the third bottom part of the pressing member is equal to or larger than the thickness of the bottom part of the upper member. Since the top part or the third bottom part of the pressing member is a member that directly engages with the first fastening member (for example, a bolt), it is more stable by increasing the thickness and increasing the strength. The solar cell panel can be fixed to the attachment object.

  Further, the second fastening member is a plate-like member having an upper surface and a lower surface, and on the upper surface, there are a first recess group composed of recesses arranged in a row, and a second recess group parallel to the first recess group. The two lip portions of the lower member have falling portions at opposite ends of the lower member, and a first fastening member and a second fastening member are provided at the lower ends of the falling portions. It is preferable that a convex group that engages with each of the first concave group and the second concave group when formed together is formed.

  With the above configuration, it is easy to maintain the engagement state between the second fastening member and the two lip portions of the lower member. Further, when the first fastening member is a bolt and the second fastening member is a plate-like nut having a female screw hole, the second fastening member rotates when the first fastening member is fastened to the second fastening member. It becomes easy to prevent this, and the attachment work to the attachment target object of a solar cell panel becomes easy.

  Here, the lower member, the upper member, the intermediate member, and the pressing member are made of a metal material having excellent strength such as aluminum, aluminum alloy, stainless steel, or iron. Furthermore, at least one is preferably formed by bending one rectangular plate-like member containing stainless steel. Stainless steel has an excellent rust prevention effect and good durability. Further, since the bending process is easy, the manufacture of each member can be facilitated, and sufficient strength can be easily secured for each member. As a result, it is possible to easily manufacture a support unit for fixing solar cell panels of various thicknesses to an attachment object, and flexibly respond to the difference in the size of the solar cell panel, and the solar cell panel is to be attached. Can be fixed to objects.

  In particular, the upper member is preferably formed by bending one rectangular plate-like member containing stainless steel. Thereby, it becomes easy to form the connection part of the curvature radius R1 between the 2nd bottom part and 2nd side part of an upper member. And it becomes easy to push the space | interval of the 2nd 2 side part of an upper member wide by inserting a pressing member in the inside of an upper member. For example, when the upper member is made of aluminum or an aluminum alloy, the elastic coefficient is small. Therefore, it is difficult to increase the distance between the two second side portions of the upper member by inserting the pressing member into the upper member. It becomes.

  In addition, by the support structure of this invention, the solar cell panel attached to an attachment target object is not restricted to one, Two or more solar cell panels can be attached independently or connected. In addition, the number of support units used to attach one solar cell panel to an attachment object is not limited to two, and three or more support units are appropriately used to attach one solar cell panel to the attachment object. Can be attached to. Even in that case, the portion of the solar cell panel supported by one support unit faces the portion of the solar cell panel supported by the other one support unit.

(Embodiment 1)
Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1A and 1C, the support structure of the solar cell panel which concerns on one Embodiment of this invention is expanded and shown with a front view. 1B and 1D show side views thereof. FIG. 1E shows an example of an overall view of the support structure in a plan view. FIG. 1F is a plan view showing another example of the overall structure of the support structure.

  Hereinafter, an embodiment of the present invention will be described by taking as an example the case where the solar cell panel 1 (1A to 1L) is attached to the slope 2 facing the south of the triangular roof (see FIGS. 1E and 1F). The X direction indicated by the arrows in FIGS. 1E and 1F is the direction along the maximum slope line of the slope between the ridge 3 and the eaves 4. In the case of a general roof, the X direction is a direction along the rafter. 1A and 1C are views seen from the X direction. The Y direction is a direction along the ridge 3. FIGS. 1E and 1F show a state in which the slope 2 is viewed with a line of sight along a direction perpendicular to the slope 2.

  The illustrated support structure 100 (100A, 100B) includes a plurality of support units 10 (10A, 10B). Each support unit 10 includes a lip groove steel lower member 102 attached to the inclined surface 2 in parallel with the X direction, a shape steel upper member 104 (104A, 104B) disposed on the lower member 102, and a lower member 102. A grooved steel intermediate member 106 disposed between the member 102 and the upper member 104, a grooved steel pressing member 108 disposed inside the upper member 104, and the upper member 104 being fastened together. A pair of first fastening members (bolts) 110 and second fastening members (plate-shaped nuts) 115 are provided. Each of the lower member 102, the upper member 104, the intermediate member 106, and the pressing member 108 can be formed by bending a single rectangular plate-shaped member containing stainless steel.

  The solar cell panel 1 includes a solar cell 5 formed on a glass substrate and a frame 6 that holds the periphery of the solar cell 5. The frame 6 can be formed from aluminum or an aluminum alloy. The shape of the solar cell panel 1 can be a rectangle, for example. Below, the case where the shape of the solar cell panel 1 is a rectangle is demonstrated.

  The lower member 102 is connected to the bottom part (first bottom part) 112, the two side parts (first side part) 114 rising from the pair of sides of the bottom part 112, and the two upper parts of the two side parts 114, respectively. Two lip portions 116 are provided, and the two lip portions 116 are fixed to the slope 2 as an attachment object with the lip portions 116 facing upward or obliquely upward. At the center of the bottom 112 of the lower member 102, a hole 119 of a main screw (bolt) 117 for fixing the lower member 102 to the roof and a hole of a temporary screw (screw) 121 for accurately tightening the main screw 117 are provided. 123 are formed on both sides of the hole 119 of the main screw 117, respectively.

A specific method for attaching the lower member 102 to the attachment object will be described with reference to FIG. 10 in the case where the lower member 102 is attached to a folded-plate roof (a vertical roof type roof made up of roof plates connected by fastening). The lower member 102 is attached on the ridge portion 125 of the folded plate roof along the vertical direction. The positions of the main screw 117 of the lower member 102 and the holes 119 and 123 of the temporary screw 121 are marked on the ridge portion 125, and a lower hole is opened. At this time, burrs are formed in the hole 119 of the main screw 117 by burring. Next, the caulking is filled in the prepared hole, and an elastic sheet 127 of about 2 mm is placed thereon. It is preferable to use butyl rubber for caulking and a butyl sheet as the elastic sheet 127 in terms of elasticity, waterproofness, heat resistance, and the like. The lower member 102 is placed on the elastic sheet 127 so that the lower hole of the temporary screw 121 is positioned at the position of the hole 123 of the temporary screw 121, and the temporary screw 121 is tightened into the hole 123. Fix it. Thereafter, the main screw 117 is tightened into the hole 119 and fixed. Furthermore, the supporting structure can be stably fixed by forming a female screw with a main screw 117 in the burr portion of the prepared hole and tightening it.

Moreover, when attaching to a tile roof, the lower member 102 can be fixed to the field board part on the rafter of a roof. As will be described later, since the solar cell panel 1 is supported by the support unit at least on a pair of sides perpendicular to the rafters, the lower member 102 is installed along the rafters.

  The upper member 104 includes at least one of a rectangular bottom portion (second bottom portion) 118, two side portions (second side portions) 120 (120A, 120B) rising from a pair of sides of the bottom portion 118, and two side portions 120, respectively. It has the bending part 122 provided in a row by the upper end part. The upper member 104 is disposed on the lower member 102 so that the side of the lower member and the side of the upper member are orthogonal to each other with the bottom 118 facing down. That is, the upper member 104 is placed on the lower member 102 so that the axial direction of the lower member 102 and the axial direction of the upper member 104 are substantially perpendicular.

  The intermediate member 106 falls from a rectangular main portion 124 that abuts the two lip portions 116 of the lower member 102 and a pair of sides of the main portion 124, and is engaged with the two side portions 114 of the lower member 102. A pair of engaging portions 126 are provided. The lower surface of the bottom portion 118 of the upper member 104 is in contact with the upper surface of the main portion 124.

  Since the solar cell panel 1 is mainly installed in a high place such as a roof of a building or a vast land, it is often exposed to a strong wind. At this time, the force which pushes up the solar cell panel 1 by the wind which wraps around the lower side of the solar cell panel 1 works. Then, when the frame 6 of the solar cell panel 1 is lifted, an upward force is also applied to the two lip portions 116 of the lower member 102, and the lip portion 116 tends to warp upward. As a result, the distance between the two lip portions 116 is increased. On the other hand, by covering the intermediate member 106 from above the lower member 102, the pair of engaging portions 126 engage with the two lip portions 116 from the outside. Therefore, it is possible to prevent the gap between the two lip portions 116 from expanding due to the above-described causes, and to stably install the solar cell panel.

  The holding member 108 has a rectangular top portion 128 and two side portions (third side portions) 130 that rise from a pair of sides of the top portion 128. The pressing member 108 is disposed inside the upper member 104 with the axial direction (direction in which the shaped steel extends (material axis direction), the direction perpendicular to the paper surface in FIG. 1A) parallel to the axial direction of the upper member 104. In the pressing member 108, lower end portions 130 a of two side portions (third side portions) 130 are in contact with lower end portions of the two side portions 120 of the upper member 104.

  As shown in FIGS. 6 to 9, a bolt hole 144 </ b> A for passing a shaft portion of the bolt 110 is inserted into the top portion 128 of the pressing member 108, the bottom portion 118 of the upper member 104, and the main portion 124 of the intermediate member 106, respectively. 144B and 144C are provided. As shown in FIG. 1B, the distance between the two lip portions 116 of the lower member 102 is larger than the diameter of the shaft portion of the bolt 110.

As a result, the solar cell panel 1 can be supported more stably. And since the connection part 142 has the curvature radius R1, the two side parts 120 (120A, 120B) can be smoothly spread. At this time, by forming the upper member 104 from stainless steel, it becomes easy to obtain a desired radius of curvature R1, and it becomes easy to push the two side portions 120 (120A, 120B) by pushing the pressing member 108. .

  Furthermore, since the connection part 142 which is a main part which contacts the lower end part of the two side parts 130 of the pressing member 108 has an appropriate radius of curvature R1, the contact area between the lower end part of the side part 130 and the connection part 142 can be reduced. The load can be increased and the load can be more effectively distributed.

  And it is preferable that the space | interval L3 of the internal dimension of the upper end part of the two side parts 120 (120A, 120B) of the upper member 104 is larger than said space | interval L1. Thereby, it becomes easy to put the pressing member 108 into the upper member 104. Furthermore, an appropriate radius of curvature is also applied to a connecting portion (not shown) between the two side portions 120 (120A) of the upper member 104 and the bent portion 122, so that the pressing member 108 is placed in the upper member 104. It is even easier to put in.

  Further, the thickness of the side portion 130 is set so that the two side portions 130 (120A, 120B) of the upper member 104 can be effectively spread by the two side portions 130 of the pressing member 108. It is preferably equal to or greater than the thickness of 120A, 120B).
