  Hereinafter, the present invention will be described in more detail with reference to the example of the drawings. Reference numeral 1 denotes, for example, a solar cell array installed on a school building roof of an elementary and junior high school. The solar cell array 1 is a solar cell array according to a conventional method. A large number of packaged solar battery panels 10 are inclinedly arranged on a gantry 12, and at this time, the solar battery panels 10 are respectively formed on the outer periphery of a substrate on which solar battery cells are fixed. A metal outer frame 11 made of a material is arranged.

  The solar cell array 1 includes an outer frame guard 2 that covers the outer frame 11 of the solar cell panel 10 that defines the outer periphery thereof, and a buffer material that covers the outer frame guard 2 by providing a buffer function to the outer frame guard 2. In this example, in addition to the buffer material 3a, the buffer device has a buffer function at the orthogonal end of the outer frame guard 2 at the corner of the solar cell array 1. The corner cushioning material 3b which is provided and covers the outer frame guard 2 is provided.

  The outer frame guard 2 that covers the outer frame 11 of the solar cell panel 10 is placed upright from the frame 12 of the solar cell array 1 upward or outward and covers the outer frame 11 in the longitudinal direction. It is formed of a hard long material having the upright piece 21 that performs.

  In this example, the outer frame guard 2 is made of a metal, such as an aluminum extruded material or a steel plate processed material, or a synthetic resin such as a hard synthetic resin extruded material, and has a thickness of about 2 to 3 mm. The outer frame guard 2 is formed of a material and has a height of about 7 to 8 cm. In this example, the outer frame guard 2 has an upright piece 21 and an upper end of the upright piece 21 on the inner side, that is, the solar cell panel 10. The section of the solar cell panel 10 having a rectangular shape is provided with a horizontal piece 22 bent toward the outer frame 11 side, for example, with a horizontal piece 22 having a protruding width of about 2 to 3 cm. It has the same length or a multiple of the same length.

  The outer frame guard 2 is fixed to the frame 12 of the solar cell array 1 and covers the outer frame 11 of the solar cell panel 10 in the longitudinal direction on all or a plurality of sides of the outer periphery of the solar cell array 1. In the example, the frame 12 is fixed to the support frame in the frame 12 at a predetermined interval in the longitudinal direction as shown in FIGS. 2 and 3, and the support frame in the frame 12 as shown in FIGS. Through the brackets 23 screwed to the joist frame in the crossing direction at predetermined intervals in the extending direction, the outer frame guard 2 is brought out from the gantry 12 to the outer position in accordance with the height of the outer frame 11, The outer frame 11 is covered, and the fixing to the gantry 12 via the bracket 23 is performed by metal fitting or adhesion, and in this example, the metal frame is fixed by the metal fitting. The fixing by the metal fittings is for supporting frame fixing by changing the orientation of the frame fixing piece 24, and for fixing the joist frame, two types of brackets 23 corresponding to the difference between the longitudinal direction of the supporting frame and the crossing direction. The bolts 26 are respectively inserted into the upper and lower through holes provided in the support pieces 25 of the brackets 23 from the upper and lower through holes provided in the outer frame guard 2. This is done by fastening a nut 27 to the bolt 26 on the frame side. At this time, the outer frame guard 2 of this example, including the horizontal piece 22, is not in contact with the outer frame 11 of the solar cell panel 10, and between the outer frame 11, in particular, the standing piece 21, for example, several The coating is performed so as to arrange a gap of about cm, and when an impact is applied to the outer frame guard 2, the impact is prevented from being directly transmitted to the solar cell panel 10, The solar battery panel 10 is protected as much as possible by avoiding troubles such as damage of the solar battery cells that may be caused by the direct transmission.

  The cushioning material is a long cushioning material 3a that covers the outer frame guard, and a corner cushioning material that covers the outer frame guard 2 that is orthogonal to the corner of the solar cell array 1 that is used in this example. 3b, the long cushioning material 3a covering the outer frame guard 2 is fixed to contact with the outer surface of the upright piece 21 of the outer frame guard 2 A piece 31, a cross projecting piece 32 projecting toward the outer frame 11 so as to form an L-shaped cross section from the contact fixing piece 31, and a U-shaped cross section or a C-shaped cross section outside the contact fixing piece 31. It is formed by a soft and long piece of thermoplastic elastomer having a buffer cover piece 33 that is arranged in a shape and covers the outer surface of the contact fixing piece 31. Further, the corner cushioning material 3b covering the outer frame guard 2 at the corner is made of the contact fixing piece 31, the cross projecting piece 32, and the cushioning cover piece in the same manner as the cushioning material 3a made of the soft long material. 33 is formed of a soft integral L-shaped material of thermoplastic elastomer having two orthogonal sides, and each longitudinal end portion of the long cushioning material 3a is connected to the contact fixing piece 31 and the cushion cover piece of the two orthogonal sides. 33, the longitudinal ends of the cushioning material 3a made of the long material are freely connected to each other.

  That is, the long buffer material covering the outer frame guard 2, that is, the buffer material 3 a formed by the long material, covers the outer frame guard 2 positioned on an arbitrary side of the solar cell array 1 in the longitudinal direction. The straight line is made of a molding material having the same cross-sectional shape in the longitudinal direction formed by extrusion molding, and the corner cushioning material 3b is for a corner part protecting two orthogonal sides of the outer frame guard 2. As a thing, it shall make the plane L shape shape | molded by injection molding.

  The cushioning material 3a and the corner cushioning material 3b are both formed by subjecting the thermoplastic elastomer to the extrusion molding or injection molding, and are made of the thermoplastic elastomer. As a cushioning material that is itself soft and integrated and exposed to direct sunlight, good weather resistance is ensured and its durability is ensured. At this time, since the buffer materials 3a and 3b are made of the above-mentioned soft one, the buffer cover piece 33 is lifted as described later, and the contact fixing piece 31 is removed by using, for example, a tap screw 38. In this example, the cushioning materials 3a and 3b can be fixed to the frame guard 2 by adding a pigment so as to exhibit an appropriate color tone, for example, white, The presence of the solar cell array 1, particularly the solar cell panel 10, can be easily recognized.

  The cushioning material 3a and the corner cushioning material 3b are both provided with the contact fixing piece 31, the cross projecting piece 32, and the cushioning cover piece 33. The size of the buffer material 3a is made larger than that of the buffer material 3a so that the end portion in the longitudinal direction of the buffer material 3a can be received in the space between the contact fixing piece 31 and the buffer cover piece 33.

  In this example, the cushioning material 3a is formed by extruding to a thickness of 2 to 3 mm, the width of the plane is 2 to 3 cm, and the height of the front is 5 to 6 cm. The contact fixing piece 31 is formed so as to form a wall standing upright at 5-6 cm, and the upper end or the upper end of the contact fixing piece 31 is formed. A cross projecting piece 32 having a projecting width of about 1 cm toward the back side and a reduced thickness in the projecting direction is disposed in the vicinity, and an arc of about ¼ circle is formed from the front side end of the cross projecting piece 32. By projecting to the front side and projecting a bent piece 34 having a length of about several millimeters toward the contact fixing piece 31 at the lower end, a U-shaped section or a C-shaped section is obtained. The buffer cover piece 33 having a slightly short size is arranged, The impact member 3 a forms a space between the contact fixing piece 31 and the buffer cover piece 33, and this space is disposed between the bent piece 34 and the contact fixing piece 31 at the lower end of the buffer cover piece 33. For example, it communicates downward by a gap of about 1 mm.

  At this time, the cushioning material 3a is a single or a plurality of, in the present example, a single intermediate buffer at the upper and lower intermediate positions between the contact fixing piece 31 and the buffer cover piece 33 in the cushioning material. It is assumed that the piece 35 is arranged, and the intermediate buffer piece 35 protrudes from the position slightly above the vertical center position of the buffer cover piece 33 to a length substantially the same as the bent piece 34 of the buffer cover piece 33, The space is divided into upper and lower sections, and the intermediate buffer piece 35 has a space of, for example, about 1 mm between the contact fixing piece 31 in the same manner as in the bent piece 34, and 2 The divided upper and lower spaces are communicated with each other, and rain water and dew condensation water of the buffer material 3a are drained by the gaps.

  In this example, the corner cushioning material 3b is similarly formed by injection molding to a thickness of 2 to 3 mm, the width is increased by about 1 cm, the height is increased by about 0.5 cm, and the length of one side perpendicular to each other is set. It is an integral molding material having a flat L-shape of 7 to 8 cm. By this, the longitudinal end of the straight cushioning material 3a is received and orthogonally connected. For this reason, the corner cushioning material 3b has a basic shape substantially the same as the straight cushioning material 3a, and forms a series of continuous cushioning materials 3a and 3b in a state of being orthogonally connected by the corner cushioning material 3b. Thus, the installation appearance is good.

  That is, the corner cushioning material 3b is formed such that the contact fixing piece 31 forms a wall surface standing upright perpendicularly to the above-mentioned 5 to 6 cm, and protrudes from the upper end to the vicinity of the upper end of the contact fixing piece 31 toward the back side. A cross projecting piece 32 having a reduced thickness in the projecting direction is arranged with a length of about 3 cm, projecting to the front side from the front side end portion of the cross projecting piece 32 and projecting to the front side with an arc of about 1/4 circle. The buffer cover having a U-shaped cross section or a C-shaped cross section by projecting a bent piece 34 having a length of several millimeters toward the contact fixing piece 31 and slightly shorter than the contact fixing piece 31. It is assumed that the pieces 33 are arranged orthogonally so as to define an outer angle, whereby the cushioning material 3b forms a perpendicular L-shaped space between the contact fixing piece 31 and the cushion cover piece 33. The space is formed by the bent piece 3 at the lower end of the buffer cover piece 33. And Taise' was placed between the fixed piece 31, for example so as to communicate with the downward by a gap of about 4 mm, it is to be drained rain water or dew condensation Similarly corner cushioning material 3b.

  At this time, the corner cushioning material 3b receives the straight cushioning material 3a in the space without providing an intermediate cushioning piece as provided in the cushioning material 3a, That is, it is assumed that the anti-slip protrusions 36 of the straight-line cushioning material 3a are arranged at two positions above and below the surface facing the buffer cover piece 33. In this example, the protrusions 36 are arranged horizontally in the space. It is a linear small protrusion protruding in a linear shape.

  Further, in this example, the corner cushioning material 3b protrudes from one side to the other at or near the crossing position between the contact fixing piece 31 and the cushion cover piece 33, or a partition cushion piece 37 connecting them. The partition buffer piece 37 of this example is arranged so as to form a partition wall that connects the contact fixing piece 31 and the buffer cover piece 33 at the crossing position. The space is divided into two so as to form two chambers that open in the crossing direction at orthogonal positions.

  Each buffer material 3a, 3b in this example is installed on the outer frame guard 2, covers the outer frame guard 2, and gives a buffer function to the outer frame guard 2. In the installation, the cushioning material 3a is preceded and the corner cushioning material 3b is followed.

  That is, the cushioning material 3a, for example, places the cross projecting piece 32 of the cushioning material 3a on the upper surface of the horizontal piece 22 of the outer frame guard 2 so as to be positioned, and performs positioning. In this state, the buffer cover piece 33 at the intermediate position excluding both ends in the longitudinal direction is lifted so as to be partially lifted to partially expose the contact fixing piece 31 on the back surface thereof, such as a nail, a screw, etc. By screwing the metal fitting 38, in this example, a tapping screw into the side surface of the outer frame guard 2 from the contact fixing piece 31 and into the front surface of the outer frame guard 2 viewed from the operator, the cushioning material 3a is removed. The frame guard 2 is fixed at a predetermined interval in the longitudinal direction. At this time, since the buffer material 3a is a soft molding material made of the thermoplastic elastomer, if the hand is released from the buffer cover piece 33, the buffer cover piece 33 returns to its original state, and the buffer material 3a is fixed. It is possible to cover the head of the metal fitting 38 and, in this example, the screw head, to improve the installation appearance.

  After the cushioning material 3a is fixed, the corner cushioning material 3b is directed to the corner of the outer frame guard 2 at the inner corner. Similarly, the cross projecting piece 32 is placed on the upper surface of the horizontal piece 22 of the outer frame guard 2 perpendicular to the corner. The buffer cover piece 33 is lifted up in the same manner and lifted in the same manner and fixed to the metal fittings 38 at two places in the crossing direction, and then divided in the crossing direction. What is necessary is just to insert the longitudinal direction edge part of each shock absorbing material 3a which cross-fixed previously in the space | interval, and to receive this shock absorbing material 2a in each space of a corner shock absorbing material, and to perform the orthogonal connection.

  The cushioning material 3a is also inserted into the corner cushioning material 3b by using the cushioning material 3a as a molding material by extrusion molding of a thermoplastic elastomer, so that the end of the cushioning material 3a is floated from the outer frame guard 2 so as to be bent by hand. If necessary, this can be done so that the cushion cover piece 33 of the corner cushioning material 3b is rolled up and fitted so as to be inserted into the space. It is possible to improve the appearance of the housing.

  Thus, covering of the outer frame guard 2 with the cushioning material 3a and the corner cushioning material 3b can be performed by some tools such as the cushioning materials 3a and 3b, the metal fitting 38 and a screwdriver, and the covering operation is performed as described above. This can be done very easily using the softness of the thermoplastic elastomer.

  In this way, the entire outer periphery of the outer frame guard 2 is covered with the cushioning material 3a and the corner cushioning material 3b so that the roof user touches the solar cell array 1 by moving it on the rooftop. And the outer frame guard 2 protects the solar panel 10 and the cushioning materials 3a and 3b exhibit a cushioning function to eliminate the danger of the rooftop user as much as possible and ensure their safety. it can. At this time, the buffer members 3a and 3b of the present example have a buffer cover piece 33 having a U-shaped cross section or a C-shaped cross section, so that the bent piece 34 at the lower end improves the buffer function and the buffer material 3a. In this case, the intermediate buffer piece 35 is disposed at the upper and lower intermediate positions of the buffer cover piece 33, so that the intermediate buffer piece 35 absorbs an impact and further improves the buffer function. In the same manner, by disposing the partition buffer piece 37, the shock absorbing function is further improved by absorbing the shock, and the corner cushioning material 3b receives the end of the cushioning material 3a in the space and superposes both of them. Since the buffer function is combined, it is possible to exhibit an advanced buffer function particularly in a corner where danger is great.

  Further, since the thermoplastic elastomer formed with the buffer materials 3a and 3b itself exhibits excellent weather resistance, it is on the roof of the installation place of the solar cell array 1 exposed to the natural environment including direct sunlight, Good durability which can maintain and exhibit the buffer function over a long period of time can be ensured.

  The example shown in the figure is as described above. However, it is necessary to cover the outer frame guard so as to reach the corner by using a hard long cushioning material alone, and in this case, cut the buffer cover piece. Put, for example, to be installed on the outer frame guard so as to bend and cover the corner portion of the outer frame, when the intermediate buffer piece is arranged on the buffer material, to further improve the buffer function by making it a plurality of up and down, Similarly, when placing the partition cushion pieces on the corner cushioning material, install them in the vicinity of the intersecting position, and at this time, further improve the cushioning action by using a plurality of the partition cushion pieces, depending on the material of the outer frame guard The metal fitting for fixing the cushioning material is appropriately selected, and adhesion is used for the fixing, the outer frame guard is formed into a long plate shape by standing pieces, and the solar cell array installed outside the roof In implementing the present invention, including applying a shock absorber, etc., a solar cell array, a solar cell panel, an outer frame guard, a cushioning material, its cross projecting piece, a contact fixing piece, a buffer cover piece, as required Each of the specific shapes, structures, materials, relations, additions to these, etc., such as intermediate buffer pieces, corner buffer materials, crossing projecting pieces, contact fixing pieces, buffer cover pieces, partition buffer pieces, etc. Various forms can be employed without departing from the gist of the invention.
