Description

  The present invention relates to a fixing member for a solar cell module.

  The conventional solar cell module can be directly attached to the base plate without using a roofing material. As shown in FIG. 10, among the frames of two solar cell modules adjacent to each other in the direction perpendicular to the flow direction, the locking portion 62 formed on the ridge-side frame 61 of the eave-side solar cell module is a field plate. The ridge side fitting portion 64 that is fixed to the ridge side 31 and formed on the ridge side frame 61 of the eaves side solar cell module is formed on the eave side frame 60 of the ridge side solar cell module. It is fitted to the part 63.

  However, in the conventional solar cell module, since the locking portions 62 for attaching the frame body to the base plate 31 are integrally provided at a predetermined pitch, rafters that support the base plate 31 are arranged at predetermined intervals. There is a case where the position of the solar cell module does not match the position of the locking portion 62 of the solar cell module, and the locking portion 62 is not fixed to the rafter, and there is a problem that the fixing strength of the solar cell module is lowered.

  Moreover, since the eaves side frame body 60 and the ridge side frame body 61 of a solar cell module are the shapes which are different, and also there exists a complicated process in order to form the securing part 62, it has led to the cost increase.

  Therefore, the present invention has a structure in which the fixing member can be slid to solve the problems of the conventional solar cell module, and further, the solar cell module leads to cost reduction by reducing the number of parts of the frame of the solar cell module. It is an object of the present invention to provide a fixing member.

The fixing member of the solar cell module according to the present invention is “fixing the solar cell module in which the outer periphery of the solar cell panel body whose outer shape is a polygonal shape is supported by the first frame and the second frame to a predetermined support member. A fixing member for the solar cell module for extending to the left and right, and a fixing portion for fixing to a predetermined support member, and a bottom extending continuously outward from either one of the left and right ends of the fixing portion, A vertical bar rising upward from the bottom side, and an upper side extending from the upper end of the vertical bar to the left and right substantially parallel to the bottom side and on which the first frame body of the solar cell module is placed. A pedestal, a shaft that extends directly above the vertical bar in the height adjustment pedestal, extends upward from the center of the upper side, contacts the side surface of the first frame, and is substantially parallel to the upper side from the upper end of the shaft. Extending to both the left and right sides, abutting the upper surface of the first frame, or first And wherein the body is obtained by forming a predetermined cross-sectional shape and a bonding portion which is inserted into the joint portion of the formed concave side surface "of. Moreover, the fixing member of the solar cell module according to the present invention is, in addition to the above-described configuration, “ having a water stop rubber further on the height adjusting pedestal portion and the bottom portion of the fixing portion ”. Features. Furthermore, the fixing member of the solar cell module according to the present invention is characterized in that, in addition to the above configuration, “ one or two fixing screw holes are further provided at a predetermined position of the fixing portion ”. It shall be the.

  According to the present invention, since the position of the fixing member can be freely moved with respect to the first frame body, for example, when fixing to a roof base plate as a support member, a rafter that supports the base plate at a predetermined interval, etc. By sliding the fixing member to a position where the structural member is located and attaching the fixing member to that position, the fixing member can be attached more firmly, and the solar cell module can be more firmly fixed. Moreover, since the adjacent first frame bodies are joined to each other via the fixing member by the pedestal part and the joined part, the two adjacent first frame bodies can be fixed by the fixing member, and the solar cell module It is possible to simplify the labor required for installation of the solar cell module, and it is possible to fix any solar cell module to the support member.

  According to the present invention, since the solar cell module is provided with a portion that connects the base portion and the joined portion and restricts the movement of the solar cell module to the outside along the surface, the fixing member is free along the first frame. However, since the relative movement can be restricted in the perpendicular direction, for example, a fixing member is attached to the solar cell module near a predetermined position, and the fixing member is detached from the first frame during installation. In this state, the solar cell module can be fixed, and the labor for installing the solar cell module can be simplified.

  The cross-sectional shapes of the first frames arranged adjacent to each other may be joined so as to be symmetrical with each other, whereby the shape of the first frame is symmetrical on both the eaves side and the ridge side. Since it can be made into the same shape, the common component of the first frame and the mold of the first frame can be shared, leading to cost reduction of the solar cell module body.

  Further, a movement restricting means including an engaging portion formed on the first frame and an engaged portion formed on the fixing member may be provided, whereby the first frame and the fixing member are engaged. Since the mating portion and the engaged portion are engaged, the relative movement in the direction perpendicular to the longitudinal direction of the first frame body can be restricted. Further, even when a force in the opposite direction of the butt is applied, it is possible to prevent the solar cell module body from being detached due to the engagement as compared with the butt only. For example, when the engaging portion formed on the first frame and the engaged portion formed on the fixing member are engaged with each other in a pawl shape by elasticity, without being inserted from the end surface of the first frame, Since it can engage with a predetermined position, the effort concerning installation of a solar cell module can be simplified. On the other hand, when the engaging portion formed on the first frame and the engaged portion formed on the fixing member are engaged with each other in an L shape, the first frame is slid from the end surface of the first frame to obtain a predetermined shape. Although it will move to a position, it can fix more firmly compared with a pawl shape.

  According to the present invention, since the fixing member is provided with the pedestal portion, the inter-module cable necessary between the solar cell modules can be connected between the upper, lower, left and right, and the labor required for installing the solar cell module is simplified. be able to. Furthermore, by adjusting the height of the fixing member, harmony with the peripheral portion of the solar cell module can be achieved, and the aesthetic appearance is not impaired. Furthermore, ventilation can be ensured in the lower part of the solar cell module frame, and a reduction in power generation efficiency due to a temperature rise of the solar cell module can be suppressed.

  In addition, you may further comprise the 2nd frame body which supports the edge | side different from the edge supported by the 1st frame body of a solar cell panel, and, thereby, a solar cell module is a solar cell module as a polygon. Furthermore, since the shape of the second frame is symmetrical, the left and right parts of the second frame can be shared and the mold of the second frame can be shared. This can lead to cost reduction.

  As described above, according to the present invention, the fixing member for fixing the solar cell module is configured to be slidable, and further, the fixing member for the solar cell module is provided which leads to cost reduction by reducing the number of parts of the frame of the solar cell module. can do.

  As shown in FIG. 2, the inter-module cable 22 can be connected between the upper, lower, left and right depending on the height of the fixing member 3, and further, ventilation can be ensured in the lower part of the solar cell module frame. It can suppress that the power generation efficiency falls by the temperature rise of a module.

  Next, the 1st frame 1 is demonstrated based on FIG. Here, the first frame 1 (ridge side first frame 1) shown on the left side in FIG. 3 will be described, and the first frame 1 (eave side first frame 1) shown on the right side in the figure. ) Is a line-symmetric shape, and detailed description thereof is omitted. As shown in FIG. 3, the cross-sectional shape of the first frame 1 is a vertically long rectangle that is recessed around the center of the right side from the outside of the frame toward the inside of the rectangle in a U-shape to the position beyond the center of the rectangle. There are one chamfered joint 10 at the intersection between the upper side and the right side of the character, and the rectangle has diagonally two corners and two frame fixing screw holes 15. Furthermore, there is an L-shaped engaging portion 12 having an open portion on the right side extending downward from the left side slightly from the center of the bottom of the rectangle. On the other hand, an L-shaped shape having an open portion on the left side that extends straight upward from the upper part of the right side of the rectangle is formed, and a module glass 23 having solar cells necessary for power generation therefor is, for example, foamable EPDM. (Ethylene / propylene / cien / methylene) The resin 24 can be sandwiched from the left side while maintaining waterproofness. In addition, the material of the 1st frame 1 is the extrusion material of aluminum, and a color is black.

  The shape of the fixing member 3 is a horizontally long rectangle, and a vertical bar is used as a reinforcement at the center of the top and bottom sides inside the rectangle. Since the height of the rectangular vertical side and the central reinforcing side can be adjusted as the height adjusting pedestal 14, the height of the solar cell module body 9 can be adjusted. There are two body fixing screw holes 25 in the depth direction for fixing the fixing member 3 to an extension line extending rightward from the bottom of the rectangle.

The material of the fixing member 3 is, for example, an extruded aluminum material or stainless steel, and the color is silver.

  There is a water-stopping rubber 4 at the bottom of the fixing member 3 to prevent rain leakage that can be considered from the main body fixing screw 5. Furthermore, there is an effect of absorbing unevenness on the surface on the roof. The water stop rubber 4 is made of butyl rubber and has a black color.

  As shown in FIG. 4, the solar cell module frame which is one Embodiment of this invention is assembled | attached. The first frame 1 is line-symmetric and is installed facing each other. The opposing first frame 1 is fixed by a fixing member 3, and the fixing member 3 is fixed on a roof material 30 having both waterproof performance and fireproof performance by a main body fixing screw 5.

  5 to 7 are cross-sectional views schematically showing the construction procedure by enlarging the main part of the solar cell module frame in FIG. First, as shown in FIG. 5, the fixing member 3 is arranged to an approximate position with respect to a predetermined position where the fixing member 3 is to be fastened, and the ridge-side first frame 1 of the eaves-side solar cell module is placed. The joint portion 10 and the eaves side joint portion 11 of the fixing member 3 are joined. Furthermore, the engaging part 12 of the ridge side first frame 1 and the engaged part 13 of the fixing member 3 are engaged.

  Next, as shown in FIG. 6, the fixing member 3 is slid to the position of at least one structural member 32 with respect to the solar cell module body 9, and the remaining fixing members 3 are applied to the solar cell module body 9. It is slid to a position where the degree of force is almost uniform and placed on the roofing material 30 and fixed with the main body fixing screws 5. The main body fixing screw 5 can maintain the fixing strength by the field plate 31 and the structural member 32.

  As shown in FIG. 7, since grounding between the solar cell modules is necessary, the grounding metal member 17 is always installed at one place with respect to the side where the first frame bodies 1 face each other. When the first frame bodies 1 are joined to each other with a strong elastic stainless steel material, the ground metal fitting 17 is electrically grounded by damaging the aluminum alumite layer on the surface of the first frame body 1 due to repulsion. It will come out. Then, after fixing the fixing member 3 with the fixing screw 5, the grounding metal member 17 is engaged with the L-shaped engaging portion 12 having the open portion of the solar cell module body 9 on the eave side, and the solar cell module on the ridge side is engaged. The eaves side first frame 1 is joined by the joint 10 and the joint 11 of the fixing member 3.

  As shown in FIG. 8, an eaves edge decorative cover 6 can be installed on the eaves side of the solar cell module array 8 to enhance the beauty. The eaves-end decorative cover 6 has a quadrant with a rounded shape on the eave side, and an L-shaped engagement portion 26 having an open portion on the right side extending downward from the right side slightly from the center of the base of the quarter circle. The joint portion 10 and the end face decorative cover screw hole 19 are in positions symmetrical to the joint portion 10 of the first frame 1 and the frame fixing screw hole 15. Furthermore, the rounded portion extends and extends downward, and the length can be adjusted by makeup or rain. The material is an extruded aluminum material and the color is black.

  As shown in FIG. 9, the fixing member 3 can slide freely along the first frame 1 although the length in the direction parallel to the first frame 1 is short with respect to the first frame 1. The fixing member 3 is fixed using two main body fixing screws 5.

  Thus, since the solar cell module frame body of this embodiment can move the position of the fixing member 3 freely with respect to the 1st frame body 1, when fixing to the roof base plate 31, it is a predetermined space | interval. By sliding the fixing member 3 to a position where there is a structural member 32 such as a rafter that supports the base plate 31 and attaching the fixing member 3 to that position, the fixing member 3 can be attached more firmly and more firmly. It is possible to fix the solar cell module. Moreover, since the adjacent first frame bodies 1 are bonded to each other by the bonding portion 10 and the bonded portion 11 via the fixing member 3, the two adjacent first frame bodies 1 are fixed by the fixing member 3. It is possible to simplify the labor for installing the solar cell module, and it is possible to fix any solar cell module to the roof.

  Furthermore, in the solar cell module frame of this embodiment, the shape of the first frame 1 is symmetrical and can be the same shape on both the eaves side and the ridge side. Can be used in common, and the cost of the solar cell module body 9 can be reduced.

  Moreover, the solar cell module frame of this embodiment can join the 1st frame 1 arrange | positioned adjacently, and the junction part 10 of the 1st frame 1 and the to-be-joined part 11 of the fixing member 3 can further join. By fixing the fixing member 3, any solar cell module can be fixed to the structural member 32 (for example, rafter). For example, as the shape of the joint portion, there are a case where the joint portion 10 is concave and the joint portion 11 is convex, and a case where the joint portion 10 is convex and the joint portion 11 is concave.

  Furthermore, since the solar cell module frame of the present embodiment is engaged by the engaging portion 12 formed on the first frame 1 and the engaged portion 13 formed on the fixing member 3, the first frame body is engaged. The relative movement in the direction perpendicular to the longitudinal direction of 1 can be restricted. Further, it is possible to prevent the solar cell module main body 9 from being detached due to the engagement even when a force in the opposite direction of the butt is applied as compared with the butt only. For example, when the engagement portion 12 formed on the first frame 1 and the engaged portion 13 formed on the fixing member 3 are engaged in a pawl shape by elasticity, the end surface of the first frame 1 Since it can be engaged at a predetermined position without being inserted more, the labor required for installing the solar cell module can be simplified. On the other hand, when the engaging portion 12 formed on the first frame 1 and the engaged portion 13 formed on the fixing member 3 are engaged in an L shape, the end surface of the first frame 1 is engaged. Although it slides and it moves to a predetermined position, it can fix more firmly compared with a pawl shape.

  The present invention has been described with reference to preferred embodiments. However, the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the present invention as described below. And design changes are possible.

That is, in the present embodiment, the first frame 1 and the fixing member 3 provided with the engaging portion 12 and the engaged portion 13 are shown, but a fixing member 40 as shown in FIG. 11 may be used.

Moreover, it is good also as the fixing member 43 shown in FIG. Thereby, as shown in FIG. 12, in the conventional solar cell module 44 in which the engaging part 45 is formed, it can be engaged by the engaged part 46 formed in the fixing member 43. Thereby, since the solar cell module 44 and the fixing member 43 are engaged by the engaging part 45 and the to-be-engaged part 46, the relative movement with respect to a perpendicular direction can be controlled. Further, it is possible to prevent the solar cell module 44 from being detached due to the engagement even when a force in the opposite direction of the butt is applied as compared with the butt only. Furthermore, the solar cell module 44 can be installed in the building by including the joined portion 42 that joins the solar cell modules 44 arranged adjacent to each other via the fixing member 43. Further, since the position of the fixing member 43 can be freely moved with respect to the solar cell module 44, for example, the fixing member 43 is slid to a position where the structural member 32 that supports the base plate 31 at a predetermined interval, The fixing member 43 can be attached at that position.

The shape of the fixing member 43 is such that the length of the fixing member 3 is adjusted so that the conventional solar cell module 44 can sandwich the T-shaped portion of the fixing member 3, and the bonded portion 42 is provided. Further, a hook-shaped engaged portion 46 is provided at a position corresponding to the height of the engaging portion 45 of the conventional solar cell module 44 below the upper side of the T-shaped eaves side. The material is an extruded aluminum material and the color is black.

  Further, the fixing member 3 may be a fixing member 50 as shown in FIG. Accordingly, as shown in FIG. 13, the fixing member 50 can be firmly installed in a building even with a roof material 52 having a narrow width by elongating the portion facing the roof from the fixing member 3 in the flow direction of the roof. It is. Furthermore, by disposing the main body fixing screw hole 51 from the straight line with respect to the flow direction of the roof, it is possible to prevent the structural member 32 from cracking when the screws are arranged on the fibers of the structural member 32.

  14 and 15, the body fixing screw hole 25 of the fixing member 3 is adjusted to the roof material 30 by adjusting the size of the body fixing hole 54 like the fixing member 53. The fixing member 53 can be fixed by the main body fixing bolt 55 using, for example, the fixing metal fitting 56 instead of being directly installed using the screw 5. Thereby, for example, the solar cell module main body 9 can be installed on the roof material 30 having both a waterproof function and a fireproof function and the conventional roof material 57.
