Description

  The present invention relates to a fixing device for installing an installation body such as a solar cell module that generates power using solar energy or a solar collector that uses solar heat via a mount.

  In recent years, with increasing interest in global environmental problems, new energy technology using natural energy has attracted attention. As one of them, interest in systems using solar energy is high, and in particular, the spread of solar power generation systems to houses has been accelerated.

  The photovoltaic power generation system reduces household electric load by converting solar energy into electric power by using a solar cell panel as a main component. In a house, since a solar cell module is often used on a roof of a house, various structures for mounting the solar cell module on the roof have been devised.

  FIG. 58 is a perspective view schematically showing a state in which the solar cell module 103 is installed on the roof using the first conventional fixing device 110. 59 is an enlarged perspective view showing a section S1 of FIG. 60 is a cross-sectional view schematically showing a state in which the first conventional fixing device 110 is installed on the tiled roof 118, and FIG. 61 is a perspective view showing the fixing bracket 124. As shown in FIG.

  When the solar cell module 103 is fixed to the roof surface using the first conventional fixing device 110, the worker first fixes the vertical beam 101 on the roof and installs the horizontal beam 102 thereon. Next, the frame-equipped solar cell module 103 is attached to the horizontal beam 102 with bolts 104 or the like.

Specifically, when attaching the horizontal beam 102 on the vertical beam 101, the worker first attaches the plurality of vertical beams 101 to the fixing bracket 124 provided on the roof along the inclination direction X of the roof. Next, a horizontal beam 102 is arranged so as to be orthogonal to the plurality of vertical beams 101, and the horizontal beam 102 is fixed to the vertical beam by a horizontal beam fixing bracket 125 using a screw hole 112 or a through hole provided in the vertical beam 101. Fix to 101. A plurality of screw holes 113 and through holes for screwing the solar cell module 103 are provided on the horizontal rail 102, and the solar cell module 103 is fixed to each mounting position.

  However, in the above-described method, there is a problem that the fixing hole 114 or the like must be provided on the solar cell module side, and the frame of the solar cell module 103 is difficult to reduce in size. Further, since the solar cell modules 103 are individually attached, there are many fixing points such as bolts 104, and the number of work steps is large.

  Therefore, the solar cell module 103 is mounted on two adjacent frames 102 that are arranged at equal intervals in the direction Y orthogonal to the inclination direction X of the roof, which is called a horizontal rail or horizontal frame. There has been proposed a method that can reduce the man-hours for mounting and mounting (see, for example, Patent Document 1).

Furthermore, there have been proposed a mounting apparatus and a mounting method that can easily cope with various existing roofs, can easily perform rain, and can be easily fixed. (For example, see Patent Document 2)
In addition, a substantially U-shaped solar cell module insertion portion is provided on a horizontal rail attached in parallel to the roof surface at regular intervals, so that a solar cell module having no frame or a relatively simple frame is inserted, and the frame portion A technique for reducing the weight has also been proposed (see, for example, Patent Document 3).

  Usually, both the gantry and the solar cell module must be grounded. If a metal vertical beam is not used, the horizontal beam must be placed between the gantry and the solar cell module for grounding. Electrical continuity must be taken in some way.

  In view of this, a method has been proposed in which a conductive member is provided to ground the frame of the solar cell panel, and in order to obtain electrical contact with the conductive member, a coating destruction means for breaking the insulating coating formed on the surface of the frame is proposed. (For example, see Patent Document 4).

  The fixing device disclosed in Patent Document 1 is individually arranged on a roof material and fixed on the roof by a fixing metal fitting fixed on the roof. The fixing device firmly fixes the solar cell module on the crosspiece by sandwiching the end portion of the solar cell module placed across the plurality of horizontal crosspieces between the horizontal crosspiece and the outer holding member. In this case, it is possible to reduce the man-hours for screw fixing of the solar cell module, but since the vertical rail 101 as shown in FIG. 58 is not used, it is suitable for installation of the roof tile 118 as shown in FIG. Absent. This is because the arrangement interval of the fixtures 124 attached to the tiled roof does not necessarily match the width of the solar cell module 103.

  FIG. 62 is an exploded perspective view showing a fixing device 120 according to the second prior art. The fixing device 120 according to the second prior art uses a fixing bracket 124 and a gantry holding part 116 instead of the vertical rail. The gantry holding part 116 is provided with a slit 115 through which the fixing bolt 124 a of the fixing metal 124 is inserted, and the position of the horizontal beam 117 serving as a gantry can be adjusted by the width of the slit 115. In this case, even on a roof having a level difference such as a wave tile 118 or a slate tile, it is possible to match the width of the solar cell module 103 by moving the fixing position of the cross beam 117. The nut 119 fitted to the fixing bolt 124a is used to fix the frame 124 and the gantry holding member 116, and another fixing bolt 121 is used to fix the horizontal rail 117 serving as the gantry to the gantry holding member 116. Since it was used, the structure was complicated and the number of steps for installing the gantry was large. Further, since the position adjustment of the crosspiece 117 can be performed only with a short slit width, the fixing device 120 needs to have a positioning accuracy when fixing the fixing device 120 to the roof surface, and there is a defect in accuracy. There has also been a problem that the positioning must be performed again.

  FIG. 63 is a diagram schematically showing a state in which the solar cell module 103 is installed on the roof using the second conventional fixing device 120. 64 is a partially enlarged perspective view of FIG. FIG. 65A is a diagram schematically showing a first example in which the solar cell module 103 is installed on the roof using the conventional fixing device 120. FIG. 65B is a diagram schematically showing a second example in which the solar cell module 103 is installed on the roof using the conventional fixing device 120. FIG. 65 (c) is a diagram schematically showing a third example in which the solar cell module 103 is installed on the roof using the conventional fixing device 120. FIG. 65D is a diagram schematically showing a fourth example in which the solar cell module 103 is installed on the roof using the conventional fixing device 120.

  In the fixing device 120 that sandwiches the end portion of the solar cell module 103 as in the second prior art, when this is arranged on the gantry holding member 116, the groove portion of the horizontal beam 117 as shown in FIG. When the horizontal rail fixing bracket 125 covers 123, a portion where the solar cell module 103 cannot be fitted to the horizontal rail 117 is generated, and as shown in FIG. 63, a solar cell in which a large number of solar cell modules 103 are arranged on the roof. When the array 127 is used, there is a space where there is a gap at the position of the horizontal rail fixing bracket 125, and the appearance of the roof of the house is damaged.

  As shown in FIGS. 65 (a) to 65 (d), this is particularly noticeable in the arrangement of the trapezoidal roof, the triangular shape, the parallelogram, and the combined arrangement of the solar cell modules 103 having different lengths. Specifically, as shown in FIG. 65A, when the solar cell module 103 is placed on a trapezoidal roof, the solar cell is mounted on the horizontal beam fixing bracket 125 that fixes the horizontal beam 117 to the gantry holding member 116. Since the module 103 cannot be placed, the gantry holding member 116 has a bare appearance, and the roof area corresponding to the gantry holding member 116 is reduced as an area where power generation is not possible.

  In the row b of the horizontal arrangement of the solar cell modules 103, three solar cell modules 103 can be placed as the roof area, but only two pieces can be placed because they cannot be fitted and fixed to the cross beam 117 across the gantry holder 116. It will not be possible to reduce the installable area on the roof.

  In addition, as shown in FIG. 65 (b), in the triangular roof, not only the b row cannot be placed on the three rows but also the roof space where another one can be placed on the upper portion of the a row is not utilized.

  In the parallelogram-shaped roof of FIG. 65 (c), it is desirable that the a to e rows of the solar cell modules 103 are shifted in accordance with the inclination of the oblique side of the roof, but it cannot cope with this.

  The above problem is the same even when solar cell modules 103 and 105 having different sizes are used, as shown in FIG. 65 (d). Originally, the area on the roof can be generated by mounting in various combinations. It is impeded to have an area or an appearance that matches the roof shape.

  In the above-described technique, it is necessary to determine the installation position of the fixing bracket 124 or the crosspiece 117 in advance and perform the installation according to the alignment position. The accuracy of the alignment greatly affects the subsequent construction, and sometimes the fixing device 120 is used. This also requires time and effort to reposition the position.

  Therefore, in view of the problems of the prior art, the present invention has a simple structure, reduces the number of steps related to fixing of the fixing device, and does not require positioning accuracy when fixing the fixing device to a building. Therefore, it is an object of the present invention to avoid the trouble of repositioning the fixing device.

  It is another object of the present invention to reduce the mounting accuracy of the fixing bracket on the roof so that the position of the vertical rail is not affected by the position of the fixing bracket.

  Moreover, in the technique as disclosed in Japanese Patent Application Laid-Open No. H10-228707, the solar cell module is inserted from the end of the roof surface even if the solar cell module can be reduced in weight because the overall rigidity is maintained by the cross rail. Therefore, it is necessary to move the solar cell module to the installation position, which increases the number of steps.

  In addition, the end of the solar cell module may be caught by the horizontal rail, making it difficult to work, and the solar cell module may be damaged.

  Furthermore, since a specific solar cell module cannot be attached / detached after the solar cell module is arranged, it is necessary to shift all the solar cell modules arranged side by side at the time of electrical wiring and maintenance at the time of construction, which requires man-hours.

  Accordingly, another object of the present invention is to provide a fixing device that is easy to dispose on an inclined roof, has a small number of work steps, is easy to perform and is sufficiently secure.

  Further, in the technique disclosed in Patent Document 4, a new part for grounding must be provided, which increases the number of parts and requires a work for attaching the member, thereby increasing the number of steps. In particular, attaching a small member on the roof is very complicated and requires a long construction time. Moreover, it becomes a factor which causes accidents, such as sliding of components and tools.

  Accordingly, still another object of the present invention is to provide a fixing device having a grounding structure that is easy to dispose on the roof without increasing the number of parts, and has a small number of work steps and a simple construction work. is there.

Fixing device of the present invention is a fixing device for fixing the installation member to be installed in a building, is connected to the building, a base that will be formed in an elongated shape, is guided in the base wherein the base in the longitudinal direction and comprising supporting support member that will be movably formed in the first direction, movably formed in the second direction crossing the guided to the support member by the first direction Te, installation body includes a rack table that holds, and a displacement preventing member which prevents the displacement of the cradle with respect to the displacement and the support member of the support member relative to the base, it said displacement preventing member is coupled to the support member The base is sandwiched between the base and the support member by pressing a part of the base against the base.

  In addition, another fixing device of the present invention is characterized in that the peripheral portions on both sides of the installation body are respectively held by two mounts provided at intervals.

  In addition, another fixing device of the present invention further includes an installation body fixing member capable of fixing the installation body to the gantry.

  According to another fixing device of the present invention, the gantry includes a mounting portion on which the installation body is mounted, and a connecting portion that is provided closer to the building than the mounting portion and is connected to the support member. It is characterized by that.

Further, in another fixing device of the present invention , the support member includes a guide member that allows the gantry to move, and the guide member is angularly displaceable about a predetermined angular displacement axis with respect to the base. It is provided in.

  Another fixing device of the present invention is constructed by angularly displacing the base with respect to the guide member around the angular displacement axis when the base is guided by the guide member while maintaining the position of the base. The fixed position of the base with respect to the object can be arbitrarily determined.

  Further, another fixing device of the present invention is characterized in that the fixing position of the building and the base changes before and after the base is rotated 180 degrees around the angular displacement axis with respect to the guide member. .

  In addition, another fixing device of the present invention is characterized in that the angular displacement axis is provided at a position other than the intermediate portion in the longitudinal direction of the base.

Further, the alignment member, in the other fastening device of the present invention, the base is the angle between the longitudinal direction of the base in the longitudinal direction and the cradle when shifted by a predetermined angle or more, and the platform the by pressing a guide member, and having a pressing member for restricting the displacement of the frame relative to the guide member.

According to the fixing device of the present invention, there is provided a fixing device for fixing the installation member to be installed in a building, is connected to the building, a base that will be formed in an elongated shape, in the base and supporting support member that will be movably formed in a first direction is guided a longitudinal direction of the base, movably formed in the second direction crossing the first direction while being guided by the support member, installed includes a rack table that holds the body, and a displacement preventing member which prevents the displacement of the cradle with respect to the displacement and the support member of the support member relative to the base, the displacement preventing member is connected to said supporting member Then, by pressing a part of the base against the base, the base is sandwiched between the base and the support member, so that the support member is placed on the base in the entire longitudinal direction of the base. By arranging it so that it can move across, Frame which is supported by the member can be moved along the upper base in the longitudinal direction. As a result, if a base point is determined at the time of installation of an installation body, for example, a solar cell module, all subsequent installations can be performed in-situ, and the base positioning accuracy can be eased and work man-hours can be greatly reduced. it can. Further, according to the present invention, the support member supports the gantry mounted on the base, and the cradle can be fixed to the base with the displacement prevention member provided on the support member. By fastening the displacement prevention member, both the gantry and the support member can be fixed to the base at a time. Thereby, the number of processes at the time of attaching a mount frame to a base can be reduced. In addition, since the support member is guided by a long base fixed to the building and is movable in the longitudinal direction of the base, the position adjustment of the base in the longitudinal direction can be performed in a wide range. it can. Thereby, when fixing a base to a building, the precision of positioning is not required, and therefore, it does not take time to reposition the base.

  As described above, after the base is fixed to the building, the position of the gantry can be adjusted in the first direction and the second direction intersecting the first direction. This eliminates the need to accurately align the fixed position of the base with respect to the building. Regardless of the fixed position of the base, the position of the base can be adjusted. As a result, the work of fixing the base in the building can be simplified. For example, when the building is a roof and the installation body is a solar cell module, it is possible to simplify the fixing operation of the solar cell module on the roof by simplifying the base fixing operation on the roof surface. it can.

  Moreover, a frictional force can be generated between a part of the gantry and the base by the displacement prevention member. Thereby, the displacement of the gantry with respect to the base can be prevented. Accordingly, the structure for fixing the gantry and the support member and the structure for fixing the support member and the base can be used together, and the structure of the fixing device can be simplified. In addition, it is possible to reduce the labor for aligning the gantry.

  According to the invention, when the gantry is aligned, the support member that guides the gantry also moves in the first direction. At this time, since the displacement prevention member is connected to the support member, it moves together with the movement of the gantry. Therefore, it is not necessary to align the displacement prevention member with respect to the gantry, and the gantry and the base can be more easily fixed.

Further, according to another fixing device of the present invention, the peripheral portions on both sides of the installation body are respectively held by the two mounts provided at intervals, so that the peripheral portions on both sides of the installation body are held by the mounts. By doing, an installation body can be fixed more reliably. Further, as described above, since the position of the gantry can be adjusted, the first gantry to which the first gantry is coupled and the second gantry are coupled among the two gantry holding both sides of the installation body. The second base is temporarily fixed to the building, and the first base is fixed to the first base in accordance with the width of the peripheral portion of the installation body to be held. Two mounts can be fixed to the second base. Thus, even when the peripheral portions on both sides of the installation body are held by the two mounts, the position of the second mount relative to the first mount can be adjusted, so that the position adjustment of the second base is performed accurately. There is no need.

According to another fixing device of the present invention , the installation body is further fixed to the gantry by the installation body fixing member by further including an installation body fixing member capable of fixing the installation body to the gantry. As a result, the installation body can be more securely fixed to the building. For example, the installation body fixing member is realized including a cover body that holds the installation body in cooperation with the gantry. Further, it is not necessary to form a bolt hole or the like for fixing to the mount on the installation body, and the installation body can be reduced in size and weight.

Moreover, according to the other fixing device of the present invention , the gantry includes a mounting portion on which the installation body is mounted, and a connecting portion that is provided closer to the building than the mounting portion and is connected to the support member. Thus, the connecting portion is formed on the building side, for example, on the lower side with respect to the mounting portion. As a result, the mount does not form a portion where the mount of the mount is hindered due to the formation of the connecting portion, and can mount the installation body over the entire surface of the mount. Therefore, the number of installation bodies that can be arranged in the building can be increased.

  In addition, since the gantry is mounted on the base with the support member, it is possible to place the installation body on the gantry without blocking the mounting portion for mounting the installation body provided on the gantry. It becomes possible, the exposed gap of the base between the installation bodies does not occur, and the roof appearance is not impaired. Further, the roof area corresponding to the gap by the base is not deleted from the area available for photovoltaic power generation. For example, it is also possible to place the installation body by shifting it for each row according to the shape of the trapezoidal, triangular, parallelogram roof, so that it becomes possible to select the arrangement of various installation bodies, It becomes possible to improve the area ratio of the installation body in the same installation surface. In addition, it is possible to easily cope with the case where the installation bodies having different sizes are used.

  Further, even when a large number of mounts are arranged on the base when a large number of small solar cell modules are used, the support member can be moved, so that any interval (an irregularity with different intervals) can be obtained. It is also possible to support the arrangement of the pedestals by the number of units, and since the number of fixing steps of the pedestal, the displacement prevention member, and the solar cell module is small, the effect of reducing the number of installation steps is larger than the conventional method.

According to another fixing device of the present invention, the guide member can be angularly displaced about an angular displacement axis with respect to the base, thereby maintaining the position of the base without removing the base from the base. The mounting position of the fixing device can be adjusted according to the state of the building. In addition, since the number of components is small and the structure is simple, it can be manufactured at low cost, the number of mounting steps can be reduced, and since it is lightweight, it is easy to handle even on the roof and can be operated safely.

In addition, according to another fixing device of the present invention, before and after the base is rotated 180 degrees around the angular displacement axis with respect to the guide member, the fixing position of the building and the base changes, Two fixed arrangements can be selected without changing the longitudinal direction of the base. Therefore, it is possible to avoid an inconvenient fixing position and select another fixing position without changing the direction of the optimum base for fixing the gantry.

Further, according to another fixing device of the present invention , the angular displacement axis is provided at a position other than the intermediate portion in the longitudinal direction of the base so that the base is angularly displaced with respect to the base. The fixed position fixed to the building can be changed.

According to another fixing device of the present invention, when the angle formed by the longitudinal direction of the base and the longitudinal direction of the gantry is shifted by a predetermined angle or more, the gantry and the guide member are pressed, and the gantry with respect to the guide member Since the pressing member for restricting the displacement of the base is provided on the base, the base is pressed against the guide member only by shifting the angle formed by the longitudinal direction of the base and the longitudinal direction of the base by a predetermined angle or more. Since the gantry is fixed, the gantry can be fixed very easily.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

  The following is an example of the first embodiment of the present invention, in which a solar cell module, which is a flat roof installation body, is disposed on a roof using a gantry, and based on the drawings schematically illustrated. This will be described in detail. For example, the roof surface is provided inclined from the horizontal plane 29.

Further, the locking portion 65 of the gantry support member 2 and the first engagement portion 50 of the gantry 5 are coupled to each other. Further, the locking portion 73 of the gantry fixing member 3 and the second engaging portion 49 of the gantry 5 are engaged with each other. The first engagement portion 50 and the second engagement portion 49 of the gantry 5 are formed by the engagement portion 63 of the gantry support member 2 and the locking portion 73 of the gantry fixing member 3 when the bolt 4 is tightened. It is pinched. Further, when the bolt 4 is tightened, the gantry 5 is pulled downward, and the gantry support member 2 is pulled upward, so that the first engagement portion 50 and the second engagement portion 49 of the gantry 5 and the gantry support are supported. The engaging portion 63 of the member 2 is pressed by the flange portions 56 and 57 of the base rail 1. As a result, the gantry 5 becomes immovable with respect to the base rail 1 in the inclination direction of the roof 17 and the direction perpendicular thereto. However, before the bolt 4 is tightened, the gantry support member 2 can move in the inclination direction X of the roof with respect to the base rail 1, and the gantry 5 with respect to the gantry support member 2 It can move in a direction Y orthogonal to the inclination direction X of the roof.

An axis L99 of the screw hole 72 is formed perpendicular to the second inclined portion 59. That is, the axis L99 of the screw hole 72 extends upward in the inclination direction X1 as it proceeds in the normal direction upward Z1.

  The gantry fixing member 3 is formed in a substantially L shape and is formed in a shape along the first protrusion 64. The gantry fixing member 3 includes a first inclined portion 73 and a second inclined portion 70 that is connected to the first inclined portion 73 and bent 90 degrees with respect to the first inclined portion 73. The second inclined portion 70 of the gantry fixing member 3 is formed with a screw hole 71 into which the bolt 4 is screwed. The horizontal dimension L5 of the first inclined portion 73 of the gantry fixing member 3 is formed to be approximately the same as the horizontal dimension L6 of the base rail 1.

  The bolt 4 is formed on the second inclined portion 70 of the gantry fixing member 3 in a state where the second inclined portion 70 of the gantry fixing member 3 is disposed to face the second inclined portion 59 of the first protrusion 64. The screw hole 71 is inserted and screwed into the screw hole 72 of the second inclined portion 59 of the first protrusion 64. As a result, the gantry fixing member 3 is attached to the gantry support member 2. The first inclined portion 73 of the gantry fixing member 3 is disposed substantially parallel to the first inclined portion 58 of the first protrusion 64. When the bolt 4 is screwed into the screw hole 72 of the gantry support member 2, the gantry fixing member 3 moves toward the flat portion 63 of the gantry support member 2 along the axis L99 of the screw hole 72. Further, in a state where the gantry fixing member 3 is mounted on the gantry support member 2, the first inclined portion 73 of the gantry fixing member 3 and the first inclined portion 58 of the first protrusion 64 have an inclination direction X and a normal line. Arranged at intervals in the direction Z.

  The gantry 5 holds the solar cell modules 11 and 23. The gantry 5 is attached to the base rail 1 via the gantry support member 2. The gantry 5 extends along the horizontal direction Y while being mounted on the base rail 1. When the gantry 5 is cut along a virtual plane perpendicular to the horizontal direction Y, a main body 51, a first collar part 49, and a second collar part 50 are formed. The main body 51 is formed in a substantially U shape. The first collar portion 49 is connected to an end portion on the X1 side in the inclination direction of the main body portion 51 b and bends with respect to the main body portion 51. The first collar portion 49 is bent from the main body portion 51 upward in the tilt direction X1, and a contact surface parallel to the tilt direction X is formed. The second collar portion 50 is connected to the lower end X2 side end portion of the main body portion 51 and is bent with respect to the main body portion 51. The second collar portion 50 extends in the normal direction downward Z2 as it proceeds from the main body portion 51 in the inclination direction downward X2.

  In a state where the gantry 5 is mounted on the base rail 1, the first collar portion 49 is disposed between the bent portions 56 and 57 of the base rail 1 and the first inclined portion 73 of the gantry fixing member 3. The At this time, the first collar portion 49 extends in parallel to face the bent portions 56 and 57 of the base rail 1. The second collar portion 50 is disposed between the bent portions 56 and 57 of the base rail 1 and the second projecting portion 65 of the gantry support member 2. At this time, the second collar portion 50 extends in parallel to the second projecting portion 65 of the gantry support member 2.

  The gantry 5 can be moved in the horizontal direction Y by being guided by the second projecting portion 65 of the gantry support member 2 while being attached to the base rail 1, and can be inclined. Movement in direction X is prevented. At this time, since the second projecting portion 65 and the second flange portion 50 are inclined with respect to the bent portions 56 and 57, the base 5 can be fixed even if the base rail 1 is inclined and fixed with respect to the horizontal plane. It can guide stably.

  Further, as the bolt 4 is screwed relative to the gantry support member 2, the gantry fixing member 3 moves toward the base rail 1 along the axial direction of the screw hole 72. Accordingly, the first inclined portion 73 of the gantry fixing member 3 presses the first collar portion 49 of the gantry 5 toward the gantry support member 2. Specifically, the 1st inclination part 73 presses the mount frame 5 toward the downward direction X2 and the normal direction downward Z2.

  Between the first collar portion 49 of the gantry 5 and the gantry support member 2, the bent portions 56 and 57 of the base rail 1 are arranged. Therefore, when the gantry 5 is pressed by the gantry fixing member 3, the first collar portion 49 of the gantry 5 is pressed against the bent portions 56 and 57 of the base rail 1. Further, the second collar portion 50 of the gantry 5 is pressed against the second protrusion 65 of the gantry support member 2. As a result, a frictional force is generated between the gantry 5 and the base rail 1, and the pedestal 5 is prevented from being displaced from the base rail 1 and the gantry support member 2.

  Further, when the first collar portion 49 comes into surface contact with the bent portions 56 and 57, a large frictional force can be obtained, and the gantry 5 can be securely fixed to the base rail 1. Further, by simply turning the bolt 4, it is possible to simultaneously prevent displacement of the gantry 5 in both the tilt direction X and the horizontal direction Y, and the gantry 5 can be fixed easily. Furthermore, by disposing the second protrusion 65 in the normal direction upward Z1 of the second collar portion 50, it is possible to prevent the gantry 5 from being displaced in the normal direction upward Z1. Further, in order to improve the frictional force, rubber or the like is provided between the contact portion between the gantry 5 and the gantry support member 3, the contact portion between the gantry 5 and the base rail 1, and between the base rail 1 and the gantry support member 3. A material having a high friction coefficient may be partially provided. Further, in order to prevent the gantry 5 from moving downward in a state where the gantry 5 and the gantry rail 1 are in contact with each other, either the gantry 5, the gantry rail 1, or the gantry support member 3, An uneven shape that engages with each other may be formed respectively. Thereby, even if the bolt is slightly loosened, it is possible to prevent the mount 5 from falling.

  Further, since the stopper support member 2 can prevent the base support member 2 from falling off, the base support member 2 can be mounted on the base rail 1 in advance before being attached to the roof. By fixing the base rail 1 in this state to the roof surface, it is not necessary to mount the gantry support member 2 to the base rail 1 on the roof surface, and workability on the roof surface can be improved.

  Accordingly, the bent portions 56 and 57 of the standing portions 61 and 62 of the base rail 1 become the flange portions 56 and 57. Further, the flat portion 63 of the gantry support member 2 becomes the engaging portion 63, the second inclined portion 59 of the first protruding portion 64 becomes the fastening receiving portion 59, and the second protruding portion 65 becomes the locking portion 65. Further, the first inclined portion 73 of the gantry fixing member 3 serves as the locking portion 73. Further, the first collar portion 49 of the gantry 5 becomes the second engagement portion 49, and the second collar portion 50 becomes the first engagement portion 50. In addition, it includes the bolt 4 and the gantry fixing member 3 and becomes a movement blocking member that prevents the gantry from moving. The fixing device 30 according to the present embodiment may not include the gantry 5.

  According to the configuration of the roof fixing device of the present embodiment, the gantry support member 2 supports the gantry 5 directly mounted on the base rail 1, and the gantry fixing member 3 attached to the gantry support member 2 includes: Since the gantry 5 can be fixed to the pedestal rail 1, both the gantry 5 and the gantry support member 2 are fixed to the pedestal rail 1 at a time by fastening one gantry fixing member 3. Can do. Thereby, the process number at the time of attaching the mount frame 5 to a roof fixing apparatus can be reduced.

  Fig.5 (a)-FIG.5 (d) are the figures which showed the construction state of an example of embodiment of this invention. The installation procedure using the roof fixing device of the present invention will be described with reference to this figure.

  First, as shown in FIG. 5A, a cross mark 14a indicating the position of the roof inclination direction of the roof fixing device closest to the eaves side is written on the roof material 7, and the roof ridge direction is based on the horizontal mark 14a. He writes Yokoshi 14b and Yoko 14c. Next, the vertical ink 15 indicating the end of the frame 5 orthogonal to the horizontal ink and the longitudinal direction of the base rail 1 is written. The roof fixing devices 30a and 30b on the most eaves side are aligned with the position of the vertical ink 15, and the front end of the eave is aligned with the horizontal ink 14 and fixed to the roof surface with the mounting screws 8 or the like. Other roof fixing devices are similarly fixed near the intersection of the horizontal ink 14 and vertical ink 15. Here, the roof fixing device 30 of the present invention can adjust the position of the gantry 5 in a wide range in the tilt direction X of the roof and the direction Y orthogonal to the tilt direction before fastening the bolts 4 as described above. Therefore, it is not necessary to precisely fix and fix the intersection of the horizontal ink 14 and the vertical ink 15.

  When the mounting of the base rail 1 is completed, the rack 52 on the most eaves side is mounted and fixed to the roof fixing devices 30a and 30b.

  Next, as shown in FIG. 5B, the next mounts 53 and 54 are sequentially attached to the building side. At this time, it is preferable that the second stage base 53 is attached while adjusting the attachment interval using the jig 16 on the basis of the first stage base 52. FIG. 6 is a cross-sectional view showing the jig 16. Since the roof fixing device 30 can adjust the position of the gantry in a wide range in the inclination direction X of the roof and the direction Y orthogonal to the inclination direction before the bolt 4 is fastened, the gantry 52 is provided on the roof fixing device 30b. In the fixed state, the mounting space between the roof fixing device 30d and the gantry 53 is adjusted by moving the gantry support member 2 of the roof fixing device 30d so that the jig 16 is fitted into the gantry 52, 53, When the bolt 4 of the roof fixing device 30d is tightened, the two adjacent bases 52 and 53 are fixed to the roof surface with a predetermined interval. The jig 16 is removed when the fixing of the gantry 53 is completed, and is similarly used for fixing the gantry 54 based on the gantry 53.

  After the mounting of all the bases is completed, the solar cell module 11 is temporarily placed across the adjacent bases 52 and 53 as shown in FIG. Similarly, the solar cell module 23 is temporarily placed between the bases 53 and 54.

  The procedure of construction on the roof of the solar cell module 11 that is a supporting object using the fixing device 130 of the present embodiment will be described with reference to FIGS.

  First, as shown in FIG. 15, a plurality of roof mounting members 32 for mounting the base rail 131 on the roof material 7 are fixed to the roof surface with mounting screws or the like. The roof mounting member 32 may be a member to be used depending on the roof material of the roof of the house to be constructed, and is not limited by the fixing device 130 of the present invention. The roof material 7 of the house includes wave tiles, slate tiles, sheet metal, etc. In this example, a slate tiled roof using plate tiles will be described as an example.

  After the base rail 131 is fixed to the roof material via the roof mounting member 32, the necessary number of base support members 132 (132u, 132s, 132t) are arranged on the base rail 131 as shown in FIG. In this example, since the solar cell array has two rows, three pedestals 135 are required, and six pedestal support members 132 are arranged. Thereafter, the gantry support member 132u located closest to the eaves of the roof is correctly positioned and fixed to the base rail 131 by the gantry fixing member 133.

  At this time, the gantry support members 132s and 132t may be aligned and fixed on the base rail 131 by the gantry fixing member 133, but in this example, they are left in a movable state.

  Next, as shown in FIG. 17, the gantry 135 (135u, 135s, 135t) is attached to the gantry support members 132u, 132s, 132t, respectively. At this time, since the bases 135s and 135t can move freely on the base rail 131 together with the base support members 132s and 132t, the base 135u already fixed when the solar cell module 11a is inserted as shown in FIG. Since the solar cell module 11a is inserted as a base point and the gantry 135s is lowered with the solar cell module 11, the positioning of the gantry 135s is automatically completed. Therefore, the work related to the positioning of the fixing device 130 in the construction is simplified. It is possible to reduce the construction man-hours.

  The state in which the solar cell module 11 is inserted into the fixing device 130 is shown in FIG. 10 in the end portion 139 (frame) of the solar cell module 11 in the opening 135b of the gantry 135 attached orthogonally on the base rail 131. Part) is inserted, and the outer clamping member 134 is clamped and fixed by pressing the solar cell module 11 against the mount 135 side.

  When the placement of the solar cell modules 11a and 11b is completed, the solar cell modules 11a and 11b are fixed by fixing the gantry 135s to the base rail 131 with the gantry support member 132s as shown in FIG.

  Similarly, after mounting the solar cell modules 11c and 11d as shown in FIG. 20, the gantry 135t is fixed to the base rail 131 by the gantry support member 132t, thereby completing the solar cell array 149.

  As described above, in the fixing device 130 of the present invention, the base rail 131 and the base support member are arranged on the base rail 131 (vertical rack) in a state where the base support member 132 can move over the entire area. Since the pedestal 135 (horizontal rack) supported by 132 can also move on the base rail 131 along the longitudinal direction, if the base point is determined when the solar cell module 11 is attached, all subsequent attachments should be done in-situ. As a result, it is possible to reduce the accuracy of the sumi dashi and greatly reduce the work man-hours.

  Further, since the gantry 135 is mounted on the base rail 131 by the gantry support member 132, the solar cell is not formed on the base rail 131 without blocking the opening 135 b into which the solar cell module 11 of the gantry 135 is inserted. The module 11 can be placed, and the exposed gap of the base rail 131 (vertical rack) does not occur between the solar cell modules 11 as shown in FIG. . Further, the roof area corresponding to the gap by the base rail 131 is not deleted from the area available for solar power generation.

  Furthermore, it is also possible to place the solar cell modules shifted for each row in accordance with the trapezoidal, triangular, and parallelogram roof shapes as shown in FIGS. 21 (b) to 21 (d). Various arrangements of solar cell modules can be selected, and the area ratio of solar power generation on the same roof can be improved.

  Specifically, in the case of the trapezoidal roof in FIG. 21 (b), there are two sheets as compared to FIG. 65 (a) which is the prior art, and in the case of the triangular roof in FIG. Compared to 65 (b), three solar cell modules 11 are added. Moreover, even when it arrange | positions using the solar cell modules 11 and 138 from which a magnitude | size differs like FIG.21 (d), it can respond easily.

  Although not particularly illustrated, when a solar cell array using a large number of small solar cell modules is used, it is necessary to arrange a number of bases 135 on the base rail 131, but the base support member 132 can move. In addition, it is possible to deal with any number of intervals (can accommodate irregular arrangements with different intervals) and horizontal frame arrangements, and since the number of fixing steps for the frame 135, the frame fixing member 132, and the solar cell module 11 is small, it is conventional. The construction man-hour reduction effect is large compared to the construction method.

  Further, as shown in FIG. 22, the base rail 131 may be sandwiched and fixed by a metal base 153 and a presser metal 152. In this case, the base rail bottom portion 158 a which is one of the rail-like locking portions provided at the lower portion of the base rail 131 is sandwiched between the upper pressing portion 153 a of the metal base 153 and the bottom portion 160 of the metal base 153. Further, if the base rail bottom 158b, which is the other of the rail-shaped locking portions provided at the bottom of the base rail 131, is sandwiched between the claw 152a of the presser fitting 152 and the bottom 160 of the metal base 153, Until the fastening bolt 154 is tightened, the base rail 131 can be moved on the metal base 153 in the direction of the roof eave and the ridge, that is, in the longitudinal direction of the base rail 131 as shown in FIG. After fixing the fastening bolt 154 to such an extent that it cannot be removed, the base 135 is fixed by tightening the fastening bolt 154 of the installation surface fixing bracket 152 after the base 135 is mounted on the base rail 131. It can be moved along with the rail 131 and positioned on the roof.

  Specifically, the base includes a base rail 131 and an installation surface fixing bracket 150. The installation surface fixing bracket 150 includes a bracket base 153 and a pressing bracket 152. The base includes a base fixing part, a base moving part, and a base coupling part. The base fixing part is fixed to the building, and is realized by the metal base 153 in the present embodiment. The base moving portion is guided by the metal base 153 and is provided so as to be movable in the tilt direction X with respect to the metal base 153, and connects the gantry support member 135. In the present embodiment, the base moving unit is realized by the base rail 131. The coupling portion prevents the base rail 131 from moving relative to the metal base 153. The base coupling portion is realized by the presser fitting 152.

  The metal base 153 is fixed to the roof surface and extends along the inclination direction X. The metal base 153 is formed in a rail shape and is formed in a substantially U shape. The metal base 153 includes a bottom portion 160 and two guide portions 161 and 162 projecting from the both sides in the horizontal direction Y of the bottom portion 160 upward Z1 in the normal direction.

  As for the 1st guide part 161 used as one of the two, the 1st front-end | tip part 153a used as the front-end | tip part extends toward the other guide part 162. FIG. That is, the bottom 160 and the first tip 153a face each other with a gap in the thickness direction Z. The first tip portion 153a is the above-described upper pressing portion 153a. The second guide portion 162 that is the other of the two extends in a direction in which the second tip portion 153 b that is the tip portion is separated from the one guide portion 161. The second tip portion 153b is formed by inserting a screw hole into which the fastening bolt 154 is screwed in the normal direction Z.

  The presser fitting 152 has a screw hole through which the fastening bolt 154 described above is inserted. The screw hole of the fastening bolt 154 is inserted through the screw hole of the second tip 153b. When the fastening bolt 154 is screwed into the second tip portion 153b, the presser fitting 152 moves toward the second tip portion 153b. The presser fitting 152 extends from the second tip portion 153b toward the first tip portion 153a. The presser fitting 152 has a claw portion 152a at the tip. In a state where the press fitting 152 is screwed to the second tip portion 153 by the fastening bolt 154, the claw portion 152a of the press fitting 152 is opposed to the bottom 160 of the fitting base 153, and is normal compared to the remaining portion of the press fitting 152. Bends in the downward direction Z2.

  The base rail 131 is formed in a long shape, and its longitudinal direction is fixed along the inclination direction X of the roof. The base rail 131 has a main body part 163 that is formed in a substantially U shape in cross section by a cut surface perpendicular to the inclination direction X, and extends in the inclination direction X. The bottom portions 158a and 158b projecting in the direction are formed.

  The base rail 131 is mounted on the bottom portion 160 while being guided by the guide portions 161 and 162 of the metal base 153. At this time, of the two bottom portions 158 a and 158 b of the base rail 131, one bottom portion 158 a is accommodated between the bottom portion 160 of the metal base 153 and the first tip portion 153 a. Of the two bottom portions 158 a and 158 b of the base rail 131, the other bottom portion 158 b is accommodated between the bottom portion 160 of the metal base 153 and the claw portion 152 a of the pressing metal 152.

  When the fastening bolt 154 is screwed into the second tip portion 153b, the presser fitting 152 comes close to the fitting base 153. As a result, the claw portion 152 a of the presser fitting 152 presses the other bottom portion 158 b of the base rail 131 against the bottom portion 160 of the bracket base 153. As a result, the base rail 131 is fixed to the metal base 153. Further, when the fastening bolt 154 is screwed off from the second tip portion 153 b, the pressing metal 152 is separated from the metal base 153. As a result, the claw portion 152 a of the presser fitting 152 is separated from the base rail 131, and the base rail 131 can be displaced in the tilt direction X with respect to the metal base 153.

  As a result, there is no problem even if the length of each of the base rails 131 protruding to the eaves side is various when the gantry 135 on the eave side is aligned horizontally with respect to the eaves of the roof. The base rail 131 does not need to be marked and the construction work becomes easier. In addition, according to this method, it is not necessary to use black ink for fixing the metal base 153, and it is needless to say that the construction is further facilitated.

  Thus, the present invention is a fixing device 130 for fixing a flat installation body, for example, a solar cell module, to an installation surface, which is a long base rail fixed on the installation surface. 131, a base support member 132 that is guided by the base rail 131 and is movable in the longitudinal direction X of the base rail 131, and is attached to the base rail 131 by the base support member 132 and is attached to the base rail 131. A long base 135 movable in a direction Y perpendicular to the base rail 131, and a fixing means for fixing the installation body by the base 135 or the base 135 and the external clamping member 134, and A fixing device 130 is provided with a gantry fixing member 132 for fixing the gantry support member 132 and the gantry 135 on the base rail 131.

The engaging part 132a provided and the engaging part 135a provided at the lower part of the mount 135 are engaged with each other.

  In the present invention, a rail-like locking portion 158a is provided on the lower surface of the base rail 131 so that the base rail 131 can move in the longitudinal direction on the installation surface on which the base rail 131 is installed. The installation surface is provided with an installation surface fixing bracket 150 for engaging with the locking portion 158a of the base rail 131.

  In this embodiment, the gantry support member 132 is clamped and fixed inside the gantry 135, but may be clamped and fixed outside, and the U-shaped rail with the base rail 131 provided with a groove on the upper surface. The gantry support member 132 may be movable inside. Further, the base rail 131 may be clamped and fixed by the installation surface fixing bracket 150 inside the base rail 131. Further, the solar cell module has been described as an example of the installation body, but the present invention is not limited to this, and can be suitably applied to a flat solar energy utilization device such as a solar collector, and the gist of the present invention. As long as it does not deviate from the above, it can be changed and implemented as appropriate.

  FIG. 25 is a cross-sectional view illustrating an example of a fixing device 180 according to the third embodiment of the present invention. In addition, about the structure corresponding to the structure of the fixing device shown in FIG. 8, the code | symbol similar to the structure of the fixing device shown in FIG. 8 is used, and description is abbreviate | omitted. In the fixing device of the present invention, as will be described later, a plurality of mounts 85 are arranged substantially parallel to each other in the ridge-eave direction of the inclined roof, and a flat plate is placed on each of the mounts 85 positioned on the ridge side and the eaves side. The solar cell modules 11 and 23 are placed on the ridge side and the eaves side, respectively, and two solar cell modules are formed in two recesses formed by the gantry 85 and the fixed cover 170 covering the gantry 85, respectively. 11 and 23, each of the ridge side and the eaves side of the fixing device 180. In particular, with respect to the solar cell modules 11 and 23 placed on the gantry 85, the fixing cover 170 and the gantry 85 Fastening means 171 for pressing between the two recesses, and a gap holding means 172 for holding the gap in the two recesses before pressing by the fastening means 171 wider than after pressing.

  First, the fixing device 180 for fixing the flat solar cell module 11 on an inclined roof will be described. As shown in FIG. 25, the fixing device 180 is fixed to the base plate 9 and the rafter through the base rail 1 with the fixing screw 8 and the roof material 7 through the sealing material 6. The sealing material 6 is preferably made of butyl rubber or foamed rubber, which has the effect of preventing the intrusion of rainwater or the like from the through portion of the roofing material 7 and the effect of buffering the load applied to the roofing material from the mount 85 described later. Use one. Further, in order to prevent rainwater from entering the fixing screw 8, a packing 8a is attached to the neck portion thereof.

  Further, since the base rail 1 is provided with a slit on the upper surface portion, and the base support member 82 is inserted into the slit, the base support member 82 can freely move in the tilt direction X in the base rail 1. Can move. The bottom portion 169 of the gantry support member 82 has a height that does not sink into the base rail 1, and the upper portion is exposed on the base rail 1. The gantry support member 3 is attached to one end of the gantry support member 82 with screws 4. Then, by fastening the screw 4, the gantry support member 82 can be fixed at an arbitrary position on the base rail 1. Note that such a structure has been described with reference to FIGS. 1 and 8, and description thereof is omitted here.

  The gantry 85 is inserted into the gantry support member 82, and the gantry 85 can be fixed together with the gantry support member 82 at an arbitrary position on the base rail 1 by tightening the screws 4. I am doing so. A fixed cover 170 is mounted on the gantry 85 with a fastening screw 171 together with a spacing member 172 which is a spacing means.

  Hereinafter, a method for installing the solar cell modules 11 and 23 on the roof using the installation body fixing device 180 of the present invention will be described in accordance with a construction procedure. As shown to Fig.26 (a), fixing device 180A-180F is fixed to roof materials 7, such as a slate tile distribute | arranged on roofs, such as a house. Then, as shown in FIG. 26 (b), 180A and 180B, 180C and 180D, and 180E and 180F of the fixing device 180 are paired and the gantry 85 (85a, 85b, 85c) is horizontally inserted on the roof at regular intervals. . At this time, the fixing cover 170 may be attached to the gantry 85 in advance with a fastening screw 171 constituting a fastening means.

  Here, the installation body fixing device 180, the gantry 85, and the fixing cover 170 are made of a metal, a resin such as an aluminum alloy or a steel material subjected to a weather-resistant surface treatment, and the like. Moreover, as shown in FIG.26 (c), the solar cell module 11 is supported by the ridge side of the mount frame 85a, and the eaves side of the mount frame 85b.

  And after arrangement | positioning of all the solar cell modules 11 and 23 and a wiring check are completed as shown to FIG. 27 (a) and FIG.27 (b), the screw | thread 171 of the fixing cover 170 of the mount frame 85a, 85b, 85c is set. The solar cell array is completed by fastening. At this time, since the solar cell modules 11 and 23 are configured such that the eaves side is hooked on the gantry 85, they do not slide down even in the temporarily placed state.

  In the present embodiment, the fixing device 180 is provided independently for each gantry 85, but may be a fixing member called a vertical beam for attaching a plurality of the gantry 85 in the inclination direction of the roof surface. Further, the length of the gantry 85 may be made longer and supported by a large number of fixing devices 180. The installation of the solar cell modules 11 and 23 may be started from the roof ridge side, or the screws may be sequentially fixed from the place where the solar cell modules 11 and 23 are placed on the gantry 85.

  Next, how the solar cell modules 11 and 23 are arranged between the gantry 85 will be described. As shown in FIG. 28, the solar cell modules 11 and 23 are formed by mounting frames 175 on the four sides of the solar cell main body 174. However, the frame 175 is not always necessary, and the solar cell modules 11 and 23 can be configured with only the solar cell body 174. The frame 175 is made of a metal material having excellent workability such as aluminum, a molded product of resin, or the like. In general, the solar cell body 174 is provided with a light-transmitting substrate such as glass or resin on the light-receiving surface, and the back material is made of a sealing material made of resin or the like in which a large number of solar cell elements are accommodated on the light-transmitting substrate. As the solar cell element, a single crystal, polycrystal or amorphous material such as a compound semiconductor made of silicon-based semiconductor or gallium arsenide is used as the solar cell element. Electrically connected, the output is taken out to the outside.

  29A and 29B, a fastening screw 171 and a spacing member 172 are attached to the fixed cover 170, and a screw fixing member 184 that constitutes a fastening means provided on the gantry 85. It can be screwed with. The interval holding member 172 may be any metal, resin, or the like that has elasticity, but further, by forming the neck portion 177 of the fastening screw 171 to prevent unnecessary loosening of the fastening screw 171. This is preferable. Further, it is more preferable to use a metal material for the spacing member 172, since electrical continuity between the gantry 85 and the fixed cover 170 can be secured and static electricity can be released. Further, it is preferable that a folding piece 178 is provided at the lower part of the fixed cover 170 so as to suppress the movement of the solar cell module 11 in the roof flow direction, that is, the roof inclination direction X when the fixed cover 170 is attached to the mount 85. It is.

  Specifically, the solar cell modules 11 and 23 are fixed to the gantry 85 by being sandwiched between the gantry 85 and the fixed cover 170. The mount 85 has an insertion hole 185 into which the fastening screw 171 is screwed. The insertion hole 185 has an axis L98 extending along the normal direction Z. The fixed cover 170 is formed with an insertion hole 136 into which the above-described fastening screw 171 is screwed. The fastening screw 171 is inserted through the insertion hole 136 of the fixed cover 170 and further through the insertion hole 185 of the gantry 85, so that the fixed cover 170 is attached to the gantry 85. At this time, the fixed cover 170 is formed with a first facing portion 190 facing the lower mounting portion 86 of the gantry 85 and a second facing portion 191 facing the upper mounting portion 87 of the gantry 85. The fixing cover 170 and the fastening screw 171 serve as an installation body fixing member that fixes the solar cell modules 11 and 23 to the gantry 85.

  In a state where the solar cell modules 11 and 23 are respectively mounted on the mounting portions 86 and 87 of the gantry 85, the fastening screw 171 is screwed toward the gantry 85, thereby fixing the fixing cover 170 to the solar cell module 11. , 23 can be pressed. As a result, the solar cell modules 11 and 23 are sandwiched between the fixed cover 170 and the gantry 85. That is, it is fixed to the roof surface.

  The spacing member 172 is provided in the vicinity of the neck portion 177 in the thread groove forming portion of the fastening screw 171 in a state where the fastening screw 171 is inserted through the fixed cover 170. The spacing member 172 includes a connecting portion 192 connected to the fastening screw 171 and spring portions 193 and 194 extending from the connecting portion 192 to both sides, respectively. The spring portions 193 and 194 extend in directions away from each other and extend in a direction away from the head 195 of the fastening screw 171 in the axial direction of the fastening screw 171. The spring portions 193 and 194 have elasticity. The connecting portion 192 is formed with a through hole 137 that penetrates in a state where the fastening screw 171 is screwed.

  In this state, when the fastening screw 171 is screwed into the gantry 85, the spring portions 193 and 194 of the spacing member 172 abut on the upper surface of the gantry 85. Further, when the fastening screw 171 is screwed into the gantry 85, the fixed cover 170 moves toward the gantry 85, and the solar cell modules 11 and 23 are sandwiched between the fixed cover 170 and the gantry 85. At this time, the spacing member 170 is elastically deformed, and a force in a direction away from the gantry 85 is applied to the fixed cover 170. When the fastening screw 171 is loosened, the fixed cover 170 is held in a state where the distance from the gantry 85 is large by the spring force applied from the distance holding member 172. Further, since the two spring portions 193 and 194 are formed, the interval holding member 172 can accurately hold the interval with the fixed cover 170 without biasing the spring force. The spacing member 172 may be a nut through which the fastening screw 171 passes.

  Next, how the solar cell modules 11 and 23 are fixed by the gantry 85 and the fixing device 180 will be described. As shown in FIG. 30, when the solar cell modules 11 and 23 are fixed between the bases 85a and 85b attached to the fixing devices 180a and 180c fixed on the roof, first, in the opening 176c that is a recess of the base 85b. The ridge side peripheral portion 92 of the solar cell module 11 is inserted. At this time, since the fixed cover 170b is pulled upward by the interval holding member 172b attached to the fastening screw 171b described above, a state that is wider in the ridge direction than the state in which the fastening screw 171b is tightened is held. The opening 176c can secure a sufficient depth for inserting the solar cell module 11. Accordingly, the eaves side peripheral portion 91 of the solar cell module 11 can enter the ridge side with respect to the fixed cover 170a attached to the upper portion of the mount 85a. Therefore, the eaves side 91 is connected to the fixed cover 170a and the mount. It inserts into the opening part 176a which is a recessed part comprised with 85a. At this time, if the solar cell module is not disposed on the eaves side of the gantry 85a, the fastening screw 171a is tightened. Thereby, the eaves side peripheral part 91 of the solar cell module 11 is clamped and fixed by the fixed cover 170a and the gantry 85a.

  Next, the solar cell module 23 arranged on the ridge side of the gantry 85b is inserted into the opening 176b, which is a recess composed of the fixed cover 170b and the gantry 85b, by the same procedure, and tightened. The ridge side peripheral portion 92 of the solar cell module 11 and the eave side peripheral portion 93 of the solar cell module 23 are clamped and fixed by the fixing cover 170b and the mount 85b by tightening the screw 171b.

  FIG. 31 shows a state when the solar cell modules 11 and 23 are inserted, and FIG. 32 shows a state where the solar cell module 11 is fixed by fastening the fastening screw 171. In addition, as shown in FIG. 31, the ridge side peripheral portion 92 of the solar cell module 11 is prevented from moving toward the ridge side by the folded piece 178 provided at the lower portion of the fixed cover 170b, thereby preventing the falling off. Is done. Further, when the solar cell modules 11 and 23 are disposed on the mounts 85a and 85b, an opening (recessed portion) into which the solar cell modules 11 and 23 are inserted and fixed has a space wider than the thickness of the solar cell modules 11 and 23. It can be secured, and the workability is improved.

  Further, as described above, the fixed cover 170b is lifted upward by the interval holding member 172 attached to the fastening screw 171, so that the fastening screw 171b is loosened again so that it is tightened. In addition, a wide space is secured in the ridge direction, that is, the inclination direction X, and the solar cell module 11 can be easily removed by inserting the solar cell module 11 further into the opening 176c.

  As described above in detail, according to the fixing device 180, even in the case of an installation body using light and thin members for the frame material, for example, the solar cell modules 11 and 23, the rigidity is maintained in a state of being attached to the gantry 85. Can do. Moreover, the construction work of the solar cell modules 11 and 23 is simple and can be easily attached and detached. Moreover, even if it is the solar cell modules 11 and 23 which used the thin member for the frame material, it does not slip down at the time of temporary placement, and construction work can be performed safely.

Is formed. The main body 200 includes a first raised portion 205, an eaves-side riding portion 86, a second raised portion 206, an eaves piece 203, a ridge-side riding portion 87, a guide portion 207, and a third raised portion 208. And further formed.

  The second collar portion 50 is continuous with the first raised portion 205 of the main body portion 200. The first raised portion 205 rises from the portion continuous with the second collar portion 50 in the normal direction Z1 and continues to the eaves-side riding portion 86. The lower mounting portion 86 mounts the eaves side peripheral portion 91 of the solar cell module 11 located on the lower side, and an eaves mounting surface 201 parallel to the base rail 1 is formed. The lower riding portion 86 connects the first raised portion 205 and the second raised portion 206. The second raised portion 206 rises from the portion continuous with the lower riding portion 86 in one direction Z1 in the normal direction and continues to the eaves piece 203. The eaves piece 203 extends to face the lower mounting portion 86. The eaves piece 203 is formed with a screw hole 204 into which the fastening screw 171 is screwed. Note that the extension of the axis of the screw hole 204 passes through the lower riding portion 86.

  The eaves piece 203 continues to the upper mounting portion 87. The upper mounting portion 87 mounts the eaves side peripheral portion 93 of the solar cell module 23 located on the upper side, and a ridge side mounting surface 202 parallel to the base rail 1 is formed. The upper mounting part 87 connects the eaves piece 203 and the guide part 207. The guide portion 207 descends from the portion continuous with the upper mounting portion 87 in the other normal direction Z2. The guide part 207 inclines in the other normal direction Z2 as it progresses in one inclination direction X1. The guide part 207 connects the upper riding part 87 and the third raised part 208. The third raised portion 208 falls from the portion continuous with the guide portion 207 to the other Z2 in the normal direction and continues to the first collar portion 49.

  The fixed cover 170 is for inserting the eaves-side pressing piece 220 that presses the solar cell module 11 from the upper side, the ridge-side pressing piece 221 provided higher than the eave-side pressing piece 220, and the fastening screw 171. And a through hole 222.

  The fixed cover 170 has a folded piece 178. The folded piece 178 bends in the direction away from the ridge-side pressing piece 221 from the X1 side end of the eaves-side pressing piece 220 in the inclined direction. Further, the protrusion 223 of the fixed cover 170 protrudes from the ridge-side pressing piece 221 in the same direction as the folded piece 178.

  In the present embodiment, the fixed cover 170 has a substantially U-shaped cross section, and the upper piece is the ridge side pressing piece 221 and the lower piece is the eave side pressing piece 220. Moreover, the through-hole 222 provided in the eaves-side pressing piece 221 is a long hole, and the fixed cover 170 can take different arrangements in a pre-use state and a use state, which will be described later. Further, a downward projection 223 is provided in the vicinity of the tip of the ridge-side pressing piece 221, and the downward projection temporarily fixes the solar cell module 23 in the pre-use state, and in the use state, the solar module 23 Positioning.

  Next, FIG. 35 and FIG. 36 show a detailed procedure for attaching the solar cell module using the gantry 85 fixed on the roof by the base rail 1. FIG. 37 particularly shows the frame 85 as a center.

  As shown in FIG. 35A, when the solar cell module 11 is fixed between the bases 85a and 85b attached to the base rails 1a and 1b fixed on the roof, first, the ridge-side mounting surface of the base 85a The eaves side peripheral portion 91 of the solar cell module 11 is placed on 202. Subsequently, the ridge side peripheral portion 92 of the solar cell module 11 is mounted on the eaves side mounting surface 202 of the gantry 85b while the solar cell module 11 is tilted in the ridge direction, that is, toward the roof surface. Next, as shown in FIGS. 35 (b) and (c), the solar cell module 23 arranged on the ridge side of the gantry 85b is placed on the ridge side mounting surface 202 of the gantry 85b in the same procedure. Mount it.

  At this time, as shown in FIGS. 37 (a) and 37 (b), the peripheral portions of the solar modules 11 and 23 can be placed on the mounting surfaces 201 and 202 of the main body 200. A state in which the fixed cover 170 is fixed to the main body 200 by pressing the eaves-side pressing piece 220 of the fixed cover 170 against the eaves-side mounting surface 201 of the main body 200 at the front end of the screw 173. In addition, the peripheral portions 91 and 92 of the solar modules 11 and 23 are placed on the mounting surfaces 201 and 202 of the main body 200, and the solar module 23 is temporarily fixed by the downward projection 223 (use Previous state).

  By the way, when the solar cell modules 11 and 23 are installed, it is preferable that the solar cell module can be safely temporarily fixed and the main fixing can be performed after the wiring is confirmed in consideration of work such as wiring confirmation after the placement. Therefore, as shown in FIG. 37A, the fixing cover 170 and the gantry 85 are temporarily fixed with the fastening screw 171 in a state where the fixing cover 170 is inclined to constitute an eaves side receiving portion of the solar cell module 11. At this time, the state is not fixed on the roof where it is installed, but temporarily fixed by work on the ground, or temporarily fixed at the time of shipment from the factory and shipped, so that it is fine on the roof. It is possible to eliminate the work of tightening a large number of the fastening screws 171 engaged with the taps of the screw holes 204 of the gantry 85. Furthermore, the fastening screw 171 is prevented from loosening due to the spring property of the folding piece 178 by temporarily fixing the folding piece 178 of the fixing cover 170 with the fastening screw 171. Therefore, even if it is temporarily fixed at the time of shipment from the factory, it does not loosen during transportation and does not fall off. Further, the folded piece 178 also has an action as a stopper for positioning the solar cell module 11.

  When the arrangement of the solar cell module is completed, the wiring is checked and the like, and as shown in FIG. 36 (a), the fastening screws 171 are once loosened to move the fixed covers 170a and 170b to a movable state, as shown in FIG. 36 (b). As shown in FIG. 36C, the fixed covers 170a and 170b are moved to positions where the solar cell modules 11 and 23 are fixed, and the fastening screws 171a and 171b are tightened again. The peripheral edge portion 92 and the eaves side peripheral edge portion 93 of the solar cell module 23 are sandwiched and fixed by the fixing covers 170a and 170b and the gantry 85a and 85b. The details of loosening and tightening the fastening screw 171 are shown in FIGS. 37 (c) to 37 (e).

  Next, FIG. 38 shows a gantry 85 according to another embodiment. As shown in FIG. 38 (a), a part of the intermediate portion of the fastening screw 171 is not provided with a screw, and the fastening screw 171 is similarly provided with a non-screw forming portion 187 whose diameter is smaller than the root diameter of the screw. It is possible to prevent the screw 171 from loosening and to fall off. That is, if the fastening screw 171 is tightened deeper than the non-screw forming portion 187, even if the fastening screw 171 is loosened to the non-screw forming portion 187 due to vibration or the like, it engages with the screw at the tip than the non-screw forming portion 187 It does not loosen beyond the non-thread forming portion 187. Furthermore, as shown in FIG. 38 (b), by using the above-mentioned two loosening prevention methods in combination, even if the folding piece 178 is loosened, the non-screw forming portion 187 stops loosening. Heavy drop prevention effect is obtained.

  That is, the fastening screw 171 is once loosened, the fixing cover 170 is moved to the fixing position of the solar cell module 11, and then the fastening screw 171 is tightened again. Here, if the fastening screw 171 is provided with the non-screw forming portion 187 as described above, there is no fear of the fastening screw 171 dropping off once it is loosened, and a tool such as an electric screwdriver is used. However, the work can proceed smoothly. On the other hand, since it is possible to remove the fastening screw 171 by loosening it while pulling up, the maintainability is not impaired. Further, in order to prevent the fastening screw from falling off, the tip end portion 173 may be made larger than the inner diameter of the screw hole in a state where the fastening screw 171 is mounted on the mount 85.

  FIG. 39 is a cross-sectional view illustrating an example of a roof fixing device 300 according to the fifth embodiment of the present invention, and FIG. 40 is a perspective view illustrating a part thereof. The fixing device 300 includes a base 301 and a restriction member 302 that is provided on the base 301 and restricts the movement of the gantry 304. The base 301 and the restricting member 302 are assembled so as to be rotatable around a rotating shaft 303 with a rotating shaft 303 penetrating both members in the vertical direction. Here, the rotation shaft 303 is preferably a fastening member having a cylindrical shaft such as a rivet, a bolt, or a nut. In addition, the base 301 has a pressing portion 301a that forms a ridge in the longitudinal direction as a fixing means for fixing a gantry 304 described later.

  In the fixing device 300 shown in FIG. 39, the restriction member 302 can be rotated around the rotation shaft 303 with respect to the base 301, so that the fixing device 300 can be mounted without removing the fixing device 300 from a base 304 described later. The mounting position of the fixing device 300 can be adjusted according to the situation of the roof material 7 while maintaining the position 304. In addition, since the number of components is small and the structure is simple, it can be manufactured at low cost, the number of mounting steps can be reduced, and since it is lightweight, it is easy to handle even on the roof and can be operated safely.

  As shown in FIG. 39, in the present embodiment, the base 301 includes fixing portions 301b for roofing materials at both ends in the longitudinal direction. The rotation shaft 303 and the regulating member 302 are provided at positions that are biased toward one end side in the longitudinal direction of the base 301. Therefore, the position of the fixing portion 301b with the roofing material before and after the base 301 is rotated 180 ° with respect to the regulating member 302 changes. As a result, two fixed arrangements can be selected without changing the longitudinal direction of the base 301, so that an inconvenient fixing position can be set without changing the optimum direction of the base 301 for fixing the base 304. A different fixed position can be selected by avoiding it.

  41 and 42 are views showing a state where a long gantry 304 is guided to the roof gantry fixing device 300. FIG. FIG. 41 shows a state in which the longitudinal direction X of the base 301 and the gantry 304 are parallel. In this state, since the gantry 304 does not hit the pressing portion 301 a of the base 301, the base 301 is movable in the longitudinal direction X of the gantry 304. FIG. 42 shows a state in which the base 301 is rotated by 90 ° with respect to the regulating member 302 and the gantry 304 around the rotation shaft 303 from the movable state. In the state shown in the figure, the locking portion 304a of the gantry 304 is pressed upward by the pressing portion 301a of the base 301. Therefore, the base 301 is sandwiched between the pressing portion 301a and the regulating member 302. Also, it becomes immovable in the longitudinal direction of the gantry 304. That is, the gantry 304 is fixed to the base 301.

  Specifically, the base 301 includes a support portion 351, a pair of leg portions 352 and 353, a fixing portion 301b, and a pressing portion 301a. The support portion 351 is formed in a plate shape and extends in the tilt direction X. Each leg part 352,353 is connected to the both ends of the inclination direction X of the support part 351, and is bent from the support part 351 to the other normal direction Z2. The fixed portion 301 b is connected to the other end Z <b> 2 in the normal direction of the leg portions 352 and 353, and extends in parallel with the support portion 351. That is, the support portion 351 connects the pair of leg portions 352 and 353 and is stretched between the pair of leg portions 352 and 353. In addition, the fixing portion 301 b is formed with a screw hole 350 for fixing to the roof material 7. The pressing portions 301a are provided on both sides in the horizontal direction Y. The pressing portion 301a protrudes from the support portion 351 upward in the normal direction Z1, and pressing portion ridges 354 and 355 extending in the inclination direction X are formed. In the present embodiment, the pressing portion ridges 354 and 355 are formed on both sides in the horizontal direction Y, respectively.

  The restriction member 302 is provided so as to be relatively rotatable with respect to the support portion 351 of the base 301. The rotation axis of the regulating member 302 is provided at a position different from the center position of the base 301 in the tilt direction. The restriction member 302 is formed with a restriction main body 356 extending in parallel with the support portion 351, and restriction portion protrusions 357 and 358 formed on both sides of the restriction main body 356. The restricting portion ridges 357 and 358 protrude from the restricting main body portion 356 in the normal direction upward Z1. In the present embodiment, two restricting portion protrusions 357 and 358 are provided and extend in a predetermined direction. The restricting portion protrusions 357 and 358 are formed to be longer than at least the horizontal dimension of the pressing portion protrusions 354 and 355.

  41 and 42 are diagrams showing the regulating member 302 arranged in the first arrangement state with respect to the base 301. FIG. In the first arrangement state, the regulating member 302 is arranged between the pressing portion ridges 354 and 355 of the pressing portion 301a. At this time, the restricting portion protrusions 357 and 358 of the restricting member 302 extend parallel to the pressing portion protrusions 354 and 355. The pressing portion ridges 354 and 355 are formed in a substantially L shape, and the bent portion thereof is disposed at the uppermost Z1 in the normal direction than the remaining portions of the pressing portion ridges 354 and 355. Similarly, the restricting portion ridges 357 and 358 are formed in a substantially L shape, and the bent portion thereof is disposed at the uppermost Z1 in the normal direction than the remaining portion of the restricting portion ridges 357 and 358. Further, at least one of the pressing portion ridges 354 and 355 and the restricting portion ridges 357 and 358 is realized by a material having elasticity and flexibility.

  As shown in FIG. 41, in the first arrangement state, a gap 360 is formed between the restricting portion protrusions 357 and 358 and the base 301. In addition, the pressing portion ridges 354 and 355 protrude by a predetermined amount 361 above the support portion 351 in the normal direction Z1 above the support portion 351 in the horizontal direction Y. The gantry 304 is formed in a long shape, and its cross-sectional shape is formed in a substantially U shape. Locking portions 304a are formed at both ends in the cross-sectional shape of the gantry 304, respectively. Each locking portion 304a bends toward the inside of the gantry 304 and curves in a direction approaching each other. As shown in FIG. 41, in the state where the regulating member 302 is arranged in the first arrangement state, the gantry 304 has its locking portion 304a inserted between the regulating member 302 and the support portion 351 of the base 301. Formed possible. That is, in the first arrangement state, the gap 360 formed between the restricting portion protrusions 357 and 358 and the base 301 is formed larger than the normal dimension of the locking portion 304a. As a result, the gantry 304 is locked so as to be displaceable in the tilt direction X.

  Further, when the base 304 is angularly displaced relative to the restriction member 302 from the first arrangement state, the restriction member 302 is in the second arrangement state as shown in FIG. In the second arrangement state, the gap between the pressing portion convex portions 354 and 355 and the regulating member 302 is smaller than the normal direction Z dimension of the locking portion 304a. Therefore, as shown in FIG. 42, when the gantry 304 is locked to the restricting member 302 in the first arrangement state, when the transition is made to the second arrangement state, the locking portion 304a of the gantry 304 is connected to the restricting member 302. It is clamped by the pressing portion convex portions 354 and 355. Thereby, the displacement of the gantry 304 is prevented.

  FIG. 43 shows a procedure for adjusting the position of the fixing device 300 and fixing it to the gantry 304. As shown in FIG. 43 (a), the base 301 of the fixing device 300 and the regulating member 302 are set in the first state so that the longitudinal directions thereof are parallel to each other, and as shown in FIG. The locking portion 304 a is inserted so as to pass through the gap between the base 301 and the regulating member 302 of the roof mount fixing device 300. Next, as shown in FIG. 43 (c), after the roof mount fixing device 300 is inserted to the fixed position of the mount 304, the base 301 is moved to a position perpendicular to the mount 304 as shown in FIG. 43 (d). Rotate. At this time, in the direction of FIG. 43 (d), when it cannot be attached to the roof surface due to the interference with the step of the roof material, the base 301 as shown in FIGS. 44 (a) and 44 (b). May be rotated 180 degrees to change the mounting position on the roof surface.

  In order to explain the mounting structure of the roof mount fixing device 300 of this embodiment in more detail, it will be described with reference to FIG. The roof mount fixing device 300 includes a base 301, a restriction member 302, and a rotation shaft 303, and a locking portion 304 a of the stand 304 is sandwiched between the pressing portion 301 a of the base 301 and the restriction member 302. Yes. The base 301 is attached to the base plate 9 and the slack 10 with a mounting screw 8 through the roof material 7 through a sealing material. The mounting pieces 310 and 320 of the solar cell modules 11 and 23 are mounted on the mounting base 304 in the vertical direction, and are fixed to the mounting base 304 with the fixing screws 312 via the fixed cover 311 from the upper surface thereof.

  FIG. 45 is a diagram for explaining the relationship between the level difference between the roof material 7 and the gantry and the orientation of the roof gantry fixing device 300. As shown in FIG. 45 (a), the roofing material 7 arranged on the field board 9 has tiled roofs adjacent to each other, and this step is required when fixing the roof mount fixing device 300. It is not preferable to arrange the fixing portion of the roof gantry fixing device 300 on the roof because the roof gantry fixing device 300 is not stable. Similarly, when a hole for the mounting screw 8 is provided near the end of the roofing material 7, there is a problem that the roofing material 7 is likely to be damaged. Moreover, it is impossible to predict where the gantry 304 will be placed on the roof. Therefore, when the gantry 304 is located in the range shown in FIGS. 45A and 45B, the base 301 of the roof gantry fixing device 300 extends in the ridge side 400 with respect to the gantry 304. By doing so, the roof material can be attached while avoiding the steps, and the range from P0 to PU on the ridge side can be covered. When the gantry 304 is located in the range shown in FIGS. 45C and 45D, the base 301 of the roof gantry fixing device 300 extends in the direction extending toward the eaves with respect to the gantry 304. By doing so, the roof material can be attached while avoiding the steps, and the range from PD to the eaves side PD can be covered. Thereby, the range from the tile stacking part P1 of the roofing material 7 to the next tile stacking part P2 can be covered. When the gantry 304 is located on the ridge side 400 from FIG. 45 (a), the roof material 7 can be attached while avoiding the step in the same state as FIG. 45 (d), so the above state is repeated. By selecting the direction of the base 301 regardless of the position of the horizontal base, the roof base fixing device 300 can be attached to the roof surface while avoiding the step of the roof material. In addition, in the case of FIGS. 45B and 45C, either may be selected.

  By the way, the above-described roof mount fixing device 300 may have a structure in which a convex pressing portion 401a is provided at the center of the base 301 as shown in FIG. 46 in addition to the structure shown in FIG. In addition, as a fixing means for fixing the gantry 304, not only the pressing part 301a of the said protruding item | line but a convex protrusion and another means can be used suitably.

  As described above, in the present embodiment, in the second arrangement state, any structure may be used as long as the locking portion 304a of the gantry 304 is clamped from both sides by the base 301 and the regulating member 302. The configuration of FIG. 46 will be specifically described. In the base 301, an inclined side portion 301c is formed instead of the pressing portion 301a. The inclined side portions 301 c are provided on both sides in the horizontal direction Y of the support portion 351 and extend in the inclined direction X. The inclined side portion 301c extends in the normal direction downward Z2 as it goes outward from the support portion 351 in the horizontal direction.

  As shown in FIG. 46, in the first arrangement state, the restricting portion protrusions 357 and 358 of the restricting member 302 face the inclined side portion 301c. A gap 363 is formed between the restricting portion protrusions 357 and 358 and the inclined side portion 301c, and this gap is formed to be larger than the normal dimension 364 of the locking portion 304a of the gantry 304. As a result, the gantry 304 is mounted on the base so as to be displaceable in the tilt direction X.

  When shifting to the second arrangement state, the restricting portion protrusions 357 and 358 face the support portion 351. The gaps between the restricting portion protrusions 357 and 358 and the support portion 351 are formed smaller than the normal dimension 364 of the locking portion 304a of the gantry 304. Therefore, when the stage 304 is mounted and the second arrangement state is reached, the stage 304 is sandwiched between the restricting protrusions 357 and 358 and the support part 351. As a result, the displacement of the gantry 304 is restricted. As described above, the distance between the two members for guiding the gantry is made smaller in the second arrangement state than in the first arrangement state, so that the gantry 304 attached to the regulating member 302 and the base 301 are merely angularly displaced. The state of the gantry 304 can be switched to a movable state or a movement blocking state. That is, a member such as a bolt is not required, and convenience can be improved.

  Further, in the first arrangement state, the gantry 304 is moved to an arbitrary position with respect to the base 301, and the gantry 304 is moved to an arbitrary position with respect to the base 301 by moving to the second arrangement state. Can be fixed in position. At this time, the gantry 304 and the base 301 can be fixed simply by relatively angularly displacing the gantry 304 and the base 301. That is, the gantry 304 and the base 301 can be fixed without using bolts, and workability can be improved.

  Moreover, the shape which provided the fixing | fixed part 301b which fastens the attachment screw to the roof of the base 301 as shown in FIG. 47 may be sufficient. In other words, the support portion 351 may be cantilevered by one leg portion.

  Next, another embodiment of the present invention will be described with reference to FIG. As shown in FIG. 48 (a), the roof mount fixing device 300 is superposed in the order of the base 301, the pressing member 316, and the regulating member 302, and each is movable around the rotation shaft 303 as shown in FIG. 48 (b). The rotation shaft 303 is engaged so that The pressing member 316 is provided with two rows of protruding ridge pressing portions 316a sandwiching the rotation shaft 303 in a direction orthogonal to the longitudinal direction thereof.

  More specifically, the pressing member 316 including the support portion 351 and the pressing portion protrusions 354 and 355 shown in FIGS. 39 to 42 is provided separately from the base 301. The pressing member 316 is interposed between the base 301 and the restriction member 302 and is provided so as to be angularly displaceable around the angular displacement axis of the restriction member 302 with respect to the restriction member 302 and the base 301. The pressing member 316 has a knob portion 367 in addition to the support portion 351 and the pressing portion protrusions 354 and 355. The knob portion 367 is provided integrally with the support portion 351 and the pressing portion protrusions 354 and 355, and protrudes from the base in the radial direction of the angular displacement axis.

  As shown in FIG. 48C, after the engaging portion 304a of the gantry 304 is inserted into the gap between the regulating member 302 and the pressing member 316 of the roof gantry fixing device 300 to the fixing position of the gantry 304, FIG. ), When the pressing member 316 is rotated by a predetermined angle, the pressing portion ridge 316a of the pressing member 316 changes from the direction parallel to the longitudinal direction of the gantry 304 to the direction orthogonal to the pressing member 316. The engaging portion 34a of the gantry 304 is sandwiched between the pressing portion protrusion 316a of the pressing member 316 and the regulating member 302 at a portion where the ridge 316a and the engaging portion 304a of the gantry 304 intersect, and in the longitudinal direction of the gantry 304, Immovable.

  Furthermore, another embodiment of the present invention will be described with reference to FIG. As shown in FIG. 49 (a), the roof mount fixing device 300 overlaps the base 301, the pressing member 316, and the base 301 in this order, and the rotational shaft 303 is movable around the rotational shaft 303. Is engaged. As shown in FIG. 49A, the pressing member 316 is provided with two rows of convex pressing portions 316a in the direction orthogonal to the longitudinal direction with the rotating shaft 303 interposed therebetween. Further, a through hole 318 through which the rotation shaft 303 of the pressing member 316 is inserted is a long hole so that it can slide in the longitudinal direction of the base 301. One end of the pressing member 316 in the longitudinal direction is provided with a contact portion 316b of the first rising piece 371, the other end is provided with a second rising piece 370, and a pressing screw 317 is attached thereto. As shown in FIG. 49 (c), the roof mount fixing device 300 is inserted into the gap between the regulating member 302 and the pressing member 316 of the roof mount fixing device 300 to fix the roof mount fixing device 300 to the fixed position. 49, the pressing screw 317 of the pressing member 316 is tightened as shown in FIG. 49D, whereby the pressing screw 371 comes into contact with the mount 304, and the pressing portion 316a of the pressing member 316 is moved to the side. It moves directly below the engaging portion 304 a of the gantry 304, and the engaging portion 304 a of the gantry 304 is sandwiched between the pressing portion 316 a of the pressing member 316 and the locking member 302, and in the longitudinal direction of the horizontal gantry 304 Becomes immovable. Further, in the process of tightening the pressing screw 317, the contact portion 316b of the pressing member 316 hits the side surface of the horizontal base 304, so that the pressing screw 317 is tightened too much and the pressing portion 316a of the pressing member 316 is It is possible to prevent displacement from the engaging portion 304a of the gantry 304.

  As described above, a plurality of embodiments have been described. Among the embodiments, for the configurations that can be partially used together to configure the fixing device, the configurations of those embodiments are combined to fix the fixing device. May be realized. In this specification, the tilt direction X, the horizontal direction Y, and the normal direction Z are directions used for easy understanding. Therefore, each structure of the fixing device may be formed according to a first direction corresponding to the tilt direction X, a second direction corresponding to the horizontal direction Y, and a third direction corresponding to the normal direction Z. Such first to third directions only need to correspond to the inclination direction X, the horizontal direction Y, and the normal direction Z. That is, the first direction may not be the tilt direction, the second direction may not be the horizontal direction, and the third direction may not be the normal direction.

  In this embodiment, the gantry may be described as being movable in the horizontal direction. However, the horizontal direction does not have to be orthogonal to the longitudinal direction of the base, and intersects the longitudinal direction of the base. And what is necessary is just to be a phase direction on a roof surface. Further, the gantry referred to in the present invention may be referred to as a horizontal rack, a horizontal rail, and a horizontal gantry. Moreover, although the fixing device was fixed to the roof surface, the fixing device may be fixed to a building other than the roof.

  FIG. 52 is a plan view showing the solar cell module 11 of the present invention, and FIG. 53 is a perspective view showing an enlarged part. The solar cell module 11 is configured by combining a short-side frame 501 and a long-side frame 509 which are formed of a metal frame whose surface is covered with an insulating coating except for a part at the peripheral edge of a solar cell body having a planar rectangular shape. The projecting portion 501a is provided on the lower surface of the short side frame 501, and the portion that is mounted on the pedestal that is a grounded holding member is shaved to peel off the surface treatment portion by the insulating coating Part 501b. That is, the metal frames 501 and 509 are placed in contact with the conductors of the gantry, and the surface on which the metal frames 501 and 509 are placed is formed in a stepped shape, and as described later, The surfaces of the metal frames 501 and 509 that are in contact with the gantry are formed in steps, and at least the surface of the metal frame excluding the surface that is in contact with the gantry is covered with an insulating coating.

  FIG. 53A shows a state where the protruding portion 501a and the contact portion 501b are viewed from the back surface of the solar cell module. The long side frame 509 has a smaller thickness than the short side frame 501 so as not to have the protruding portion 501a. Further, when the protruding portion 501a of the short side frame 501 is scraped to form the contact portion 501b. Project at least higher than the long side frame 509.

  As shown in FIG. 8, the solar cell module is fixed to the roof surface by the above-described fixing devices. Referring to FIG. 8, a fastening screw 171 is attached to the fixed cover 170 so that it can be screwed with a screw hole provided in the gantry 85, and the solar cell module 23 includes the fixed cover 170 and the gantry 85. It is fixed by screwing in the state inserted between them. At this time, the abutting portions 501b of the short side frame 501 at both ends of the solar cell module 23 come into electrical contact with the gantry 85, and grounding is performed on the gantry 85. Further, the gantry 85 is electrically connected to the roof surface directly or indirectly.

  Next, how the solar cell modules 11 and 23 are fixed by the fixing devices 180a and 180b having the gantry 85a and 85b will be described with reference to FIG. When the solar cell modules 11 and 23 are fixed between the bases 85a and 85b attached to the base rail 1 fixed on the roof, first, an opening which is a recess constituted by the fixing cover 170b and the base 85b. The ridge side peripheral portion 92 of the solar cell module 11 is inserted into the portion. Thereafter, the eaves side peripheral edge 91 of the solar cell module 11 is inserted into an opening which is a recess constituted by the fixed cover 170a and the gantry 85a. At this time, if the solar cell module is not disposed on the eaves side of the gantry 85a, the fastening screw 171a is tightened.

  Thereby, the eaves side peripheral part 91 of the solar cell module 11 is clamped and fixed by the fixed cover 170a and the gantry 85a. At the same time, the contact portion of the solar cell module 11 and the bases 85a and 85b are pressed, so that the short side frame 501 and the base 85 of the solar cell module 11 are in an electrically conductive state, and the eaves side base 85a and the ridge side base 85b becomes electrically conductive.

  On the other hand, when there is the solar cell module 23 arranged on the ridge side of the gantry 85b as shown in FIG. 30, the eaves side peripheral edge 93 of the solar cell module 23 is inserted into the opening of the gantry 85b in the same procedure. Then, the fastening screw 171b is tightened so that the ridge side peripheral portion 92 of the solar cell module 11 and the eaves side peripheral portion 93 of the solar cell module 23 are sandwiched and fixed by the fixed cover 170b and the gantry 85b. Thereby, since the contact part of the solar cell module 23 and the mount 85b are pressed, the short side frame 501 and the mount 85b of the solar cell module 23 will be in an electrically conductive state.

  After the arrangement of all the solar cell modules and the wiring check are completed, the solar cell array is completed by tightening and fixing the screws of the fixing cover 170 of each mount. At the same time, the short side frame 501 of the solar cell module is completed. Therefore, the short side frame 501 and the gantry 85 of the solar cell module 11 are in an electrically conductive state. Since the short side frame 501 is mounted over the adjacent bases 85, for example, 85a and 85b, the adjacent bases 85a and 85b are also in an electrically conductive state, and all the bases 85 are in an electrically conductive state. . Therefore, if one place is grounded from any of the mounts 85, all the mounts 85 can be grounded.

  Note that the length of the gantry 85 may be made longer and supported by a large number of fixing devices 300. The installation of the solar cell modules 11 and 23 may be started from the roof ridge side, or the screws may be sequentially fixed from the place where the solar cell modules 11 and 23 are arranged on the cross rail. Further, the grounding may be performed after the installation of the gantry or the grounding may be performed from the fixing device to the ground.

  Moreover, embodiment of the grounding method which does not utilize the solar cell module frame of this invention is described using FIG. As in the above-described embodiment, a screw hole 521 for attaching a screw to the fixed cover 170 of the installed photovoltaic power generation device is provided, and a metal side cover 519 is attached to the side surface of the photovoltaic power generation device installed on the roof. At 520, it attaches to the fixed cover (for example, 170a, 170b) on an adjacent mount frame. At this time, if the periphery of the mounting screw hole 518 of the side cover 519 is not painted, that is, has electrical conductivity, electrical conduction is secured between the fixed covers 170 on adjacent frames by the side cover 519. If one place is grounded from any of the mounts 85, all the solar cell modules 11 and 23 and the mount 85 can be grounded. Further, even if the mounting screw hole 521 is painted, a structure in which the coating film (insulating coating) is broken by tightening the mounting screw 520 such as a leaf washer may be used.

  Thereby, even if the short side frame 501 and the long side frame 509 of the solar cell modules 11 and 23 are made of resin or non-conductive material, all the solar cell modules 11 and 23 and the gantry 85 can be grounded. In addition, it is possible to improve the appearance of the solar power generation device and to have a function of preventing birds and the like from entering under the solar cell modules 11 and 23.

  In this embodiment, a plurality of mounts are arranged substantially parallel to each other in the ridge-eave direction of the inclined roof, and a flat plate shape having a metal frame on each of the mounts positioned on the ridge side and the eaves side. Each of the ridge side and eave side of the solar cell module is placed, and the ridge side of the solar cell modules 11 and 23 is placed in each of two recesses formed by the gantry and the fixed cover 170 covering the gantry. And a solar power generation apparatus that accommodates each of the eaves side, and in particular, fastening for pressing between the fixed cover 170 and the gantry against the solar cell modules 11 and 23 placed on the gantry. However, the present invention is not limited to this, and appropriate methods and configurations can be employed without departing from the scope of the invention.

  The present invention can be implemented in various other forms without departing from the spirit or main features thereof. Therefore, the above-described embodiment is merely an example in all respects, and the scope of the present invention is shown in the claims, and is not restricted by the text of the specification. Further, all modifications and changes belonging to the scope of the claims are within the scope of the present invention.
