Description

  The present invention relates to a solar panel fixing structure for fixing a solar panel to acquire solar energy on a flat roof surface in which a waterproof sheet is stretched by an insulating method.

  Conventionally, as a method of forming a waterproof layer on the roof surface of a building, a waterproof sheet made of a synthetic resin such as soft vinyl chloride is directly stretched on the upper surface of a concrete slab, an ALC (lightweight cellular concrete) panel, or a hard foam A method of stretching through a synthetic resin or the like is widely used.

  In this case, if the waterproof sheet is entirely bonded to the roof surface, the waterproof sheet will follow the deformation and movement of the roof surface when the roof surface is deformed or moved due to an earthquake or the like. There is a risk that the waterproof sheet will crack. As a solution to this problem, an insulation (floating) method as described in Patent Document 1 has been developed.

  On the other hand, as described in Patent Document 2, there are a plurality of techniques from the roof surface as a technique for mounting a solar panel mounting object such as a solar power generation module or a solar water heater on a flat roof surface formed with a waterproof layer with a waterproof sheet. A method has been proposed in which an external connection body is projected and a placement object is placed and fixed on the external connection body.

  According to this method, since the edge of the placed object and the roof surface (waterproof sheet) is cut, maintenance of the waterproof sheet can be easily performed. For example, even if a heavy object such as a storage room is placed Since the load is transmitted directly from the external connection body to the beam, it is advantageous in that the waterproof sheet is not damaged.

  Patent Document 3 proposes an attachment structure that can reduce the labor for installing the solar cell module support and can reduce the number of penetrations of the waterproof layer.

JP 60-184157 A Japanese Patent Application Laid-Open No. 08-260642 JP 2005-194771 A

  However, in the above-described conventional example, in the technique of Patent Document 2, (1) the mounting position is limited because it is mounted and fixed on the flange upper surface of the beam. (2) It is necessary to adjust the dimensions of the gantry when the size of the object and the module of the building do not correspond. (3) Since the cylindrical external connector is protruded, the waterproof fit around the protrusion is complicated, and it takes time for new construction and maintenance of the waterproof sheet. (4) Since the beam is used as an anchor, preparatory work is required, and there is a problem that it is difficult to place the beam on an unplanned part.

  Further, the technique of Patent Document 3 requires a waterproof treatment because a penetration portion of the waterproof layer is generated, and further, since wind enters the lower part of the solar cell module and the pulling load increases, and a strong fixing structure is required. There is a problem that the number of fixing members is increased, and as a result, the number of penetration portions of the waterproof layer is increased, so that the waterproof process is troublesome.

  The present invention solves the above-mentioned problems, and the object of the present invention is to prevent wind from entering the lower part of the solar panel such as a solar power generation module or a solar water heater, and eliminate the penetration of the waterproof layer. It is intended to provide a solar panel fixing structure that can be installed and maintained easily.

  A first configuration of a solar panel fixing structure according to the present invention for achieving the above object is a solar panel fixing structure on a flat roof surface in which a waterproof sheet is stretched by an insulation method, and includes a rectangular solar panel and The pair of columnar members joined to the waterproof sheet stretched on the flat roof surface and the waterproof sheet stretched on the flat roof surface on the upper surface of the columnar member are placed in contact with each other and face each other in parallel. A long support base, and a panel support member that is mounted on the upper surface of the pair of long support bases and supports the solar panel at a predetermined inclination angle. The panel support member is located above the inclined solar panel. In the vicinity of the side, the wind entering the lower side of the solar panel covering the space between the solar panel and the flat roof surface in cooperation with one of the pair of long stands Characterized in that it has a windbreak portion to Decay.

  Further, a second configuration of the solar panel fixing structure according to the present invention is the same as the first configuration in which the waterproof sheet is joined to a joining plate fixed to the concrete structure of the flat roof surface by a fixing member. The columnar member is joined to the waterproof sheet in a position directly above the joining plate and avoiding a fixing member that fixes the joining plate to the concrete structure.

  Further, a third configuration of the solar panel fixing structure according to the present invention is the same as the first configuration in which the waterproof sheet is joined to a joining plate fixed to the concrete structure of the flat roof surface by a fixing member. The columnar member is disposed at a position avoiding the bonding plate and bonded to the waterproof sheet.

  According to the first configuration of the solar panel fixing structure according to the present invention, the panel support member cooperates with one of the pair of long mounts in the vicinity of the upper side of the inclined solar panel. Since it has a wind shield that works and covers the space between the solar panel and the flat roof surface and attenuates the wind entering below the solar panel, it is suppressed that the lower surface of the solar panel is directly blown by strong wind . Therefore, a solar panel that is lightweight, has a wide wind-receiving surface and is easy to be blown by strong wind is fixed with high wind resistance performance, without carrying out a large-scale construction on a waterproof sheet fixed by an insulation method having a relatively low fixing degree. I can do it.

  Moreover, according to the 2nd structure of the fixing structure of the solar panel concerning this invention, since the columnar member is not mounted on the upper part of the fixing member which fixes a joining board to a concrete structure, the fixing member which is fixing the joining board Can be easily removed, and maintenance such as replacement of the waterproof sheet can be easily performed.

  Moreover, according to the 3rd structure of the fixing structure of the solar panel which concerns on this invention, it can be set as the structure by which a columnar member is not mounted on the upper part of a joining board, and the position and solar panel of the joining board installed beforehand are made. It can also be applied when the position of the corresponding columnar member is deviated.

  An embodiment of a solar panel fixing structure according to the present invention will be specifically described with reference to the drawings. FIG. 1 is an overall perspective view showing the configuration of the first embodiment of the solar panel fixing structure according to the present invention, and FIG. 2A is a cross-sectional view showing the configuration of the first embodiment of the solar panel fixing structure according to the present invention. Explanatory drawing, FIG.2 (b) is an exploded explanatory drawing which shows the fixing structure of a columnar member, a long member, and a panel support member, FIG.2 (c) is a case where a reinforcement sheet is interposed between a columnar member and a waterproof sheet FIG. 3A is a plan view and a side view showing the configuration of the joining plate, FIG. 3B is a cross-sectional view showing the configuration of the joining plate, and FIGS. 4A and 4B. FIG. 5 is a perspective view showing an example of a long member and a panel support member, and FIG. 6 shows the present invention when the positions of the columnar member and the joining plate are shifted. It is a whole perspective view which shows the structure of 1st Embodiment of the fixing structure of the solar panel which concerns.

  First, the structure of 1st Embodiment of the fixing structure of the solar panel which concerns on this invention using FIGS. 1-6 is demonstrated. 1 and 2, a waterproof sheet 2 is stretched on the flat roof surface 1 by an insulating method. Here, the insulating method is to fix the joining plate 4 to a required portion of the wall surface of the concrete structure 3 to be waterproofed on the flat roof surface 1, and cover the entire surface of the wall surface of the concrete structure 3 with the waterproof sheet 2. By fixing, only a part of the waterproof sheet 2 is fixed, and most of the remaining part is left and the waterproof sheet 2 is stretched. According to such a technique, since the waterproof sheet 2 is bonded to the flat roof surface 1 in a point-like manner, the non-bonded portion of the waterproof sheet 2 absorbs the displacement even when the flat roof surface 1 is deformed or moved. Therefore, the possibility that the waterproof sheet 2 is cracked can be reduced.

  As the concrete structure 3, ALC (lightweight cellular concrete) panel, PC (precast) panel, reinforced concrete slab, etc. can be applied. On these concrete structures 3, insulation material made of foamed resin, mortar, incombustible plate, etc. It can also be applied to a flat roof structure in which is laminated.

  As the waterproof sheet 2, a thermoplastic synthetic resin sheet such as a soft polyvinyl chloride sheet, a polyethylene sheet, or a polypropylene sheet, a non-vulcanized rubber sheet, a rubber asphalt sheet, or the like can be applied. As the thickness of the waterproof sheet 2, for example, about 1 mm to 2 mm can be applied.

  As shown in FIG. 3, the joining plate 4 can be a metal plate such as a steel plate, or a metal plate with a sheet piece of the same material as the waterproof sheet 2 attached to the upper surface or a surface coated with the same material. Various shapes such as a circular shape, a rectangular shape, and a belt shape can be applied as the shape of the bonding plate 4, and any shape can be used as long as the insulating method can be used.

  In the vicinity of the outer periphery of the joining plate 4, a hole 4 a through which a countersunk screw 5 serving as a fixing member is passed is formed. In this embodiment, holes 4a are formed at three locations near the outer periphery of the disc-shaped joining plate 4, and the outer diameter of the columnar member 6 shown in FIG. 4 is just above the position where the hole 4a of the joining plate 4 is avoided. The size is set such that the columnar member 6 can be disposed (see FIGS. 2 and 3). In addition, the position which opens the hole 4a is not specifically limited.

  As a fixing member for fixing the joint plate 4 to the concrete structure 3, a curl plug, a spread leg nail, or the like can be applied, and a member that can obtain the required pulling strength in relation to the mating member made of the concrete structure 3 is appropriately adopted. It is good to do. Further, the number of fixing members to be used may be determined from the required pullout strength.

  In consideration of the installation position of the columnar member 6 (that is, the installation position of the solar panel 10), the joining plate 4 may be planned in advance for a fixed position on the flat roof surface 1 or applied to an existing building. The mounting position of the columnar member 6 may be determined according to the position of the bonded plate 4 fixed regardless of the installation position of the columnar member 6 (that is, the installation position of the solar panel 10).

  The joining plate 4 is fixed to the concrete structure 3 on the flat roof surface 1 by a flat head screw 5 as a fixing member, and the waterproof sheet 2 is joined to the joining plate 4 and stretched by an insulating method. Bonding between the joining plate 4 and the waterproof sheet 2 may be performed by an adhesive, but a solvent of the same material is used between the joining plate 4 whose surface is coated with the same material as the waterproof sheet 2 and the waterproof sheet 2. The joining plate 4 and the waterproof sheet 2 can be welded by applying the added welding agent. For example, a vinyl chloride welding agent can be applied and welded between a waterproof sheet 2 made of a vinyl chloride waterproof sheet and a bonding plate 4 whose surface is coated with a vinyl chloride resin.

  A columnar member 6 shown in FIG. 4 is joined on the waterproof sheet 2 stretched on the flat roof surface 1. The columnar member 6 of the present embodiment is joined to the waterproof sheet 2 by placing it at a position directly above the joining plate 4 and avoiding the countersunk screw 5 serving as a fixing member for fixing the joining plate 4 to the concrete structure 3.

  The columnar member 6 can be made of the same material as the waterproof sheet 2. However, it is necessary that the waterproof sheet 2 and the windbreak portion 7b formed of the hanging piece of the long gantry 7 be rigid enough to maintain a non-contact state. And the columnar member 6 and the waterproof sheet 2 can be welded by applying the welding agent which added the solvent of the same raw material between the columnar member 6 and the waterproof sheet 2. For example, a vinyl chloride welding agent can be applied and welded between the waterproof sheet 2 made of a vinyl chloride waterproof sheet and the columnar member 6 made of a vinyl chloride resin.

  The shape of the columnar member 6 is not particularly limited, but a columnar member or the like having no directionality is preferable. In addition, as shown in FIG. 2, it is preferable that an anchor bolt 8 for fixing the long base 7 is projected in advance from the upper end of the columnar member 6. As shown in FIG. 4, the columnar member 6 of the present embodiment is provided with a through hole 6a at a predetermined position, and a hexagonal head 8a of an anchor bolt 8 is fitted into the lower portion of the through hole 6a to be locked. A hexagonal locking hole 6b that can be connected is communicated. FIG. 4A is an example in which one through hole 6 a is provided in the center of the columnar member 6, and FIG. 4B is an example in which two through holes 6 a are provided on the diameter of the columnar member 6. is there.

  When the columnar member 6 is set right above the joining plate 4, the columnar member 6 is disposed at a position where there is no hindrance to the work of loosening the countersunk screw 5 serving as a fixing member. Replacement maintenance of the columnar member 6 is performed integrally with the waterproof sheet 2.

  Further, the columnar member 6 is not directly welded to the waterproof sheet 2, but as shown in FIG. 2 (c), a member in which the welded sheet piece 9 is welded in advance to the columnar member 6 is prepared. A welding operation may be performed between the welding sheet piece 9 and the welding sheet piece 9.

  The welding sheet piece 9 and the columnar member 6 can be made of the same material as the waterproof sheet 2, and a columnar member 6 is applied between the columnar member 6 and the welding sheet piece 9 by applying a welding agent added with a solvent of the same material. The welding sheet piece 9 and the waterproof sheet 2 are further welded by applying a welding agent added with a solvent of the same material between the welding sheet piece 9 and the waterproof sheet 2. I can do it. For example, a vinyl chloride welding agent can be applied and welded between the waterproof sheet 2 and the welded sheet piece 9 made of a vinyl chloride waterproof sheet and the columnar member 6 made of vinyl chloride resin.

  When unevenness is formed on the flat roof surface 1, welding work between the flexible welding sheet piece 9 and the waterproof sheet 2 is easier to cope with unevenness. Moreover, the columnar member 6 can be easily removed without removing the waterproof sheet 2 by cutting off the non-welded portion of the welded sheet piece 9.

  Reference numeral 10 shown in FIG. 1 denotes a rectangular solar panel for acquiring solar energy. As an example, a solar power generation module or a solar water heater can be applied. The pair of long bases 7 are placed in contact with and parallel to the waterproof sheet 2 stretched on the flat roof surface 1 on the upper surface of the columnar member 6. A panel support member 13 that supports the solar panel 10 with a predetermined inclination angle is placed on the upper surfaces of the pair of long mounts 7, and is fixed to the columnar member 6 together with the long mounts 7. The two opposite sides of the solar panel 10 are supported by the panel support member 13 with a predetermined inclination angle.

  The pair of long frames 7 and the panel support member 13 cover the space between the solar panel 10 and the flat roof surface 1 over the entire length of the two sides on which the solar panel 10 is supported, and enter the solar panel 10 below. Wind shields 7b and 13b for attenuating the wind.

  That is, the windbreak portion 13a of the panel support member 13 is located near the upper side of the inclined solar panel 10 (the water side when water flows) and one of the pair of long stands 7 and In cooperation, the wind entering the lower part of the solar panel 10 is attenuated by covering the space between the solar panel 10 and the flat roof surface 1.

  The long base 7 shown in FIG. 5 has a wind shield 7b made of a hanging piece at both ends of the horizontal piece 7a, and has a U-shaped cross section. The panel support member 13 includes a horizontal piece 13a that is in contact with the horizontal side 7a of the long gantry 7; a windbreak portion 13b that includes a pair of upright pieces that are raised from both ends of the horizontal piece 13a; A pair of support pieces 13c extending from the upper end of the windbreak portion 13b made of a piece at an equal inclination angle (on the same plane), and the length in the longitudinal direction is the length of the longitudinal frame 7 Has a length equal to the length.

  Then, the solar panel 10 and the flat roof surface 1 formed by the solar panel 10 being supported at a predetermined inclination angle by the wind shield 7b formed of the hanging piece of the long gantry 7 and the support piece 13c of the panel support member 13. Is covered with a wind shield 13b made of upright pieces to attenuate the wind entering the solar panel 10 below.

  When installing the solar panel 10, first, the joining plate 4 is fixed to the concrete structure 3 of the flat roof surface 1 with a flat head screw 5, and the waterproof sheet 2 is put on the entire surface of the flat roof surface 1 including the joining plate 4. The waterproof sheet 2 is bonded to the upper surface of the bonding plate 4.

  Next, the anchor bolt 8 is inserted into the through hole 6 a from the lower surface side of the columnar member 6, the head 8 a of the anchor bolt 8 is inserted into the locking hole 6 b and locked, and the countersunk screw is directly above the joining plate 4. The lower surface of the columnar member 6 is joined to the waterproof sheet 2 at a position where 5 is avoided.

  Next, the long base 7 and the panel support member 13 are placed on the upper surface of the columnar member 6, and the shaft of the anchor bolt 8 protruding from the columnar member 6 in the through holes 7a1 and 13a1 provided in the horizontal pieces 7a and 13a. The long base 7 and the panel support member 13 are fixed by inserting the portion 8b and screwing and fastening the nut 11 to the shaft portion 8b.

  Next, the connection hardware 12 attached to the side on which the solar panel 10 is supported is bolted to the support piece 13c of the panel support member 13 having a different height to fix the solar panel 10 at a predetermined inclination angle.

  As a material of the long gantry 7 and the panel support member 13, a metal subjected to rust prevention treatment such as stainless steel, galvanized steel or the like is preferable. Wind shield 14 for preventing wind from being blown by a wind shield 13b comprising a support piece 13c and a standing piece of a panel support member 13 for supporting the solar panel 10 at a predetermined inclination angle and a wind shield 7b comprising a hanging piece of the long frame 7. Can be formed so that the lower surface of the solar panel 10 is not directly blown up by strong wind.

  The difference in height between the pair of support pieces 13c of the panel support member 13 is not particularly limited, but can be designed in consideration of the light receiving efficiency and the like depending on the area and direction. However, it is preferable to ensure a gradient so that at least the rain dripped on the surface of the solar panel 10 flows without remaining.

  According to the said structure, a pair of panel support member 13 and the elongate mount frame 7 which support the solar panel 10 with a predetermined inclination angle cover the solar panel 10 and this flat roof surface over the full length of the side where the solar panel 10 is supported. By forming the wind shield 14 that covers the space between the solar panel 10 and attenuates the wind entering the solar panel 10, the solar panel 10 becomes difficult to be blown up by the wind, and the land roof surface 1 has a relatively fixed force. Even when the solar panel 10 that is light and has a wide wind-receiving surface and is easily blown by the wind is fixed to the waterproof sheet 2 fixed by a small insulation method, the high wind-resistant performance can be maintained, so the safety is high. .

  Moreover, the fixing member which is fixing the joining plate 4 by having set it as the structure by which the columnar member 6 is not mounted on the upper part of the flat head screw 5 used as the fixing member which fixes the joining plate 4 to the concrete structure 3 of the flat roof surface 1; The countersunk screws 5 can be easily removed, and maintenance such as replacement of the waterproof sheet 2 can be easily performed.

  In addition, since a slight gap is formed in the lower portion of the windbreak portion 7b made of the hanging piece of the long gantry 7, no water pool is formed even if there is a water gradient on the land roof surface 1, and the land roof surface 1 is When used as a rooftop, there is no hindrance and no loss of aesthetics.

  In addition, even if the long base 7 is deformed due to expansion / contraction due to a temperature change, an earthquake, or the like, the force is transmitted directly to the joining plate 4 and not to the waterproof sheet 2, so there is no risk of the waterproof sheet 2 being broken. .

  In FIG. 6, the waterproof sheet 2 is stretched by being joined to a joining plate 4 fixed to the concrete structure 3 on the flat roof surface 1 by a flat head screw 5 serving as a fixing member, and the columnar member 6 avoids the joining plate 4. It is an example at the time of arrange | positioning in the position and joining to the waterproof sheet 2. FIG. Further, as described above with reference to FIG. 2C, a reinforcing welding sheet piece 9 can be interposed between the waterproof sheet 2 and the columnar member 6.

  According to the said structure, it can be set as the structure by which the columnar member 6 is not mounted on the upper part of the joining board 4, and the position of the joining board 4 installed previously and the position of the columnar member 6 corresponding to the solar panel 10 shift | deviate. It can also be applied to

  By configuring in this way, even if deformation occurs due to expansion and contraction due to temperature change of the long gantry 7 or an earthquake or the like, deformation is allowed by the non-joined portion of the waterproof sheet 2 with the roof base (the elasticity of the waterproof sheet 2). Since the displacement is absorbed in (part), the waterproof sheet 2 is not adversely affected.

  Next, the structure of 2nd Embodiment of the fixing structure of the solar panel which concerns on this invention is demonstrated using FIG. FIG. 7 is an overall perspective view showing the configuration of the second embodiment of the solar panel fixing structure according to the present invention. In addition, what was comprised similarly to the said 1st Embodiment attaches | subjects the same code | symbol, and abbreviate | omits description.

  In the present embodiment, the panel support member 21 includes a horizontal piece 21a that is placed over the upper surfaces of the pair of long stands 7, a standing piece 21b that stands up from one end of the horizontal piece 21a, and a horizontal piece 21a. The panel support piece 21c is supported by the other end side and the upper end of the upright piece 21b and has a predetermined inclination angle, and the windbreak piece 21d is attached to the upright piece 21b.

  The solar panel 10 is supported and fixed at two sides inclined to a pair of panel support members 21 that are bridged and fixed so as to be orthogonal to the pair of long stands 7.

  A windbreak piece 21d is attached to the upright piece 21b of the pair of panel support members 21, and the windbreak piece 21d and a windbreak portion 7b made of a hanging piece of the long gantry 7 are provided between the solar panel 10 and the flat roof surface 1. A wind shield 14 is formed continuously to cover the space and attenuate the wind entering the solar panel 10, thereby covering the space between the solar panel 10 and the flat roof surface 1, and the lower surface of the solar panel 10 is strong wind. Will not be blown up directly.

  That is, in the vicinity of the upper side of the inclined solar panel 10 in which the panel support member 21 of the present embodiment is also in cooperation with one of the long frames 7, the solar panel 10 and the flat roof surface 1 is configured to have a wind shield 14 that covers the space between the two and attenuates the wind that enters the solar panel 10 downward.

  At both ends of the horizontal piece 21 a of the panel support member 21, through holes 21 a 1 for fixing screws to the horizontal piece 7 a of the long frame 7 are formed. Since the through hole 21a1 is formed outside the upright piece 21b and the panel support piece 21c, the screw can be easily attached and detached, and the solar panel 10 can be operated even when attached to the panel support member 21.

  A through hole 21c1 for fixing the solar panel 10 with screws is formed in the panel support piece 21c. Since the through-hole 21c1 is formed in a portion protruding in the width direction from the horizontal piece 21a or the standing piece 21b, the screw fixing work can be performed without being obstructed by the horizontal piece 21a or the standing piece 21b.

  Other configurations are the same as those in the first embodiment except that the horizontal piece 7a of the long gantry 7 is formed with a through hole 21a1 for attaching the panel support member 21, and the same effect is obtained. I can do it.

  When long panels 7 are arranged in parallel at predetermined intervals in three or more rows and solar panels 10 are installed in close proximity to multiple rows, the upright piece 21b side is not proximate to other solar panels 10 when it is most susceptible to wind. This is a solar panel 10 in a row (usually the northernmost row because the light receiving surface of the solar panel 10 is arranged facing the south side), and the other solar panels 10 are not significantly affected. Accordingly, the windbreak piece 21d may be attached only to the row where the upright piece 21b side is not close to the other solar panels 10. With this configuration, it is possible to reduce the labor and cost of installing the solar panel 10.

  As an application example of the present invention, the solar panel is fixed when fixing a solar panel such as a solar power generation module or a solar water heater for acquiring solar energy on a flat roof surface in which a waterproof sheet is stretched by an insulation method. It can be applied to the structure.
