Description

  The present invention relates to an installation structure on a roof of a reinforcing base provided for installing a solar cell module on a roof of a house or the like.

  Solar cells are attracting attention from the viewpoint of securing energy independent of resources and environmental protection, and the installation of solar cell modules on the roofs of houses and the like is rapidly spreading. In addition to the environmental aspect, there is a merit that it is directly connected to users such as power consumption of the home by the power generation of the solar cell module and sale of surplus power to the power company.

  Solar cell modules are usually arranged along a roof that slopes in the south direction, but in the case of a snow-free roof with a substantially flat roof, a platform with a slope that matches the latitude of the area is mounted on the roof in the south direction. A solar cell module is attached to the inclined surface. In order to prevent power generation from being lost due to snowfall in the winter season, it is necessary to install a platform in which the solar cell module is positioned above the snow-covered surface.

  For example, as shown in Japanese Patent Laid-Open No. 2000-101123, a state in which a predetermined angle is inclined by a low leg column attached to one end of a solar cell panel mounting frame and a high leg column attached to the other end is formed. There are known mounting base devices. A plate-like bottom plate is usually provided at the lower end of the column in such a gantry, and is fixed to the foundation concrete with an anchor or the like if it is flat.

  When installing such a solar cell module or mount on the roof, there is no adverse effect on the structure of the building and the waterproofness of the roof, and the solar cell module or mount is firmly fixed so as not to be damaged by strong winds etc. This is an important point. Of course, in an existing house, it is not assumed that such equipment is installed, and therefore, if the above-described frame is installed, problems such as load concentration under the column and damage to the roof occur. Therefore, various installation methods that can be installed in existing houses have been proposed.

  As an example, Japanese Patent Application Laid-Open No. 8-93159 discloses that a wooden pier is fixed to the roof surface with a screw nail or the like as a mounting base for the solar cell module, and the space between the solar cell module and the roof surface and the space between the solar cell modules. In this state, a solar cell mounting method is shown in which individual solar cell modules are detachably attached to the pier by screwing means.

  In this method, the fixing and waterproof fireproofing method of the pier is laid with waterproof paper on the entire surface of the field board, and the pier is placed along the slope of the roof in a position that overlaps the rafter through this waterproof paper. On the other hand, it is fixed using a long screw nail. The pier is further covered with waterproof paper, and is coated with a sheet metal sheet whose side edges are bent for draining, and then a colored asbestos board with new waterproof paper over the entire roof except the pier. Sealing material is applied to the corners of contact between the slab sheet metal and the colored asbestos board. According to this method, it is said that the fireproof and waterproof treatment of the roof surface can be easily implemented with the conventional specification.

JP 2000-101123 A JP-A-8-93159

  As described above, in the case of a snow-free roof having a substantially flat rooftop in a snowfall area, a pedestal is provided and the solar cell module is inclined and fixed at a high position. Therefore, the wind force acting on the solar cell module at a high position acts as a moment on the gantry base. Furthermore, since the gantry base is exposed to the sway and slight vibration of the gantry for a long period of time, there is a problem that cracks and tears occur from the fixed portion of the roof to the exterior material, leading to the entry of rainwater and snowmelt water.

  The method of installing the pier of Patent Document 2 can be said to be a good method for distributing the load applied to the base of the gantry to the contact surface between the pier and the roof so that the pier serves as a reinforcement base that also serves as a roof reinforcement. However, a single sheet steel sheet that is used for a general roof is a sheet metal sheet disposed on a pier, which is broken by shaking or slight vibration, and cannot maintain waterproofness.

  Usually, in the case of long steel plate roof, the end is folded and connected, so a thin steel plate of about 0.35 mm that can be processed is used. If a thick steel plate is used to prevent breakage, the folding process cannot be performed, and connection and waterproofing become difficult. Seams are created on the roof surface, and if it is filled with caulking material, it cannot be said that the durability is good.

  In view of this, the present invention provides an installation structure of a pier-like reinforcement base that is provided to install a solar cell module fixing member, base, etc. on the roof, even if it is exposed to a load or vibration transmitted from the base, etc. An object of the present invention is to provide an installation structure on a roof of a reinforced foundation having durability that does not break the material and is highly waterproof.

  In order to achieve the above object, the installation structure of the reinforcing base on the roof according to claim 1 of the present invention is the installation of the fixing member of the solar cell module and the base of the pier-like reinforcing base that becomes the base of the mount 31. It is a structure, the reinforcing base 10 is placed on the base plate 4, fixed to the lower structural material with the screws through the base plate 4, the heat insulation board 12 on the base plate 4 other than the reinforcing base 10, the roof The waterproof sheet 13 and the roof steel sheet 14 are layered in order, and the ends of the roof waterproof sheet 13 and the roof steel sheet 14 located around the reinforcing base 10 are raised upward along the side surface of the reinforcing base 10, and the reinforcing base 10 is mounted from the top. Covered with tarpaulin 15, and the peripheral edge of the base tarpaulin 15 is laid between the roof steel sheet 14 and the roof tarpaulin 13, and the end of the raised roof steel sheet 14 and the joint of the base tarpaulin 15 with waterproof tape 16 is attached, and the steel plate 17 and 19 is covered with the steel plate 17 and 19 from the top of the reinforcing base 10.

  Since the structure is such that the base waterproof sheet 15 and the waterproof tape 16 of the reinforcement base 10 are covered with the steel plates 17 and 19 from the top, the exterior material on the reinforcement base 10 can be secured by using a thick steel plate.

  The structure for installing the reinforcing base 10 on the roof according to claim 2 of the present invention is that the double steel plates 17 and 19 covered as the exterior of the reinforcing base 10 in the device of claim 1 have a thickness of 0.35 mm or more and 0.6. It is characterized in that two steel plates of mm or less are stacked.

  If the steel plates 17 and 19 to be coated doubly exceed 0.6 mm in thickness, it is too thick and difficult for manual sheet metal work in the short work of the reinforcing base 10 and the sheet metal folding work of the nose, and it is less than 0.35 mm Such steel plates have low strength and cannot prevent breakage. By protecting the reinforcement base 10 with a steel sheet having a thickness of 0.7 mm or more and 1.2 mm or less when two sheets are stacked, an exterior of the reinforcement base 10 that is capable of normal sheet metal work and that is not damaged can be obtained.

  According to the first aspect of the present invention, the base waterproof sheet 15 and the waterproof tape 16 of the reinforcing base 10 are covered with the steel plates 17 and 19 twice, and the exterior material on the reinforcing base 10 is made of a thick steel plate. Therefore, it is possible to provide an installation structure of the reinforcing base 10 that is highly durable and waterproof even when exposed to vibration of the gantry 31 or the like.

  According to the second aspect of the invention, the double steel plates 17 and 19 that cover the exterior of the reinforcing base 10 are made of two steel plates having a thickness of 0.35 mm or more and 0.6 mm or less, so that they are durable and waterproof. It is possible to provide an installation structure of the reinforcing base 10 that is high and that can be carried out by normal sheet metal work.

  Hereinafter, an embodiment of an installation structure on a roof of a reinforcing base according to the present invention will be described with reference to FIGS.

  FIG. 1 to FIG. 4 show a case where a solar cell module 30 is installed using a gantry 31 on a substantially flat snow-free roof 1 with a water gradient. A reinforced base 10 provided on the roof 1 is used as a base, and a base 31 is assembled with vertical and horizontal members, and the solar module 30 is inclined and fixed at a high position from the upper surface of the roof 1.

  The roof 1 shown by a present Example is constructed by a wooden frame construction method as an example, and shows a long steel plate roof as a roofing material. In the wooden frame construction method, girders and beams are built between pillars, bundles are built on the beams, a slope is formed on the main building 2 and purlins on it, and rafters 3 along the slope of the roof with a gap therebetween. Fixing is the basic structure. In snowy areas, the structure above the rafters is mainly a metal roof with a long steel plate roof because it is lightweight, strong and easy to maintain. Lay the base plate 4 on the rafters 3 without any gaps, and fix hardware such as a hanging piece on the base plate 4 and lay a heat insulation board such as extruded foam styrene board and a waterproof sheet such as asphalt roofing on it. A long steel sheet roofing material is placed, and a long steel roofing material and a hanging metal fitting are crimped and fixed.

  Next, a structure in which the reinforcing base 10 is installed on the roof 1 of the wooden frame construction method as described above will be described.

  A plurality of reinforcing bases 10 are arranged in parallel along the slope of the roof 1 on the base plate 4 on the rafter 3 and fixed to the rafter 3 as a structural material through the base plate 4 with screws 11 from the top of the reinforcing base 10. . The reinforcing base 10 is a long wooden pier with a cross section of 105 mm × 150 mm. It is desirable that the screw 11 or the like can reach the eaves under the rafter 3 or the purlin 2 as a structural material because it can be firmly fixed. In this embodiment, the rafters 3 having a cross section of 45 mm × 60 mm are arranged at intervals of 455 mm, the reinforcing bases 10 are arranged every four rafters 3 and four at intervals of 1820 mm, and the length is about 2180 mm.

  On the base plate 4 other than the reinforcing base 10, a heat insulation board 12 such as an extruded foamed styrene board, a roof waterproof sheet 13 such as an asphalt roofing sheet, and a roof steel sheet 14 that is a long steel sheet roof material are laid in order. The heat insulating board 12 may be urethane foam or the like. Further, the roof waterproof sheet 13 may be a waterproof sheet made of synthetic rubber, vinyl chloride, resin or the like used for waterproofing the membrane.

  At this time, the end portions of the roof waterproof sheet 13 and the roof steel plate 14 located around the reinforcing base 10 are raised upward along the side surface of the reinforcing base 10. Then, the reinforcing base 10 is covered with the base waterproof sheet 15 from above, and the peripheral edge of the base waterproof sheet 15 is laid between the roof steel sheet 14 and the roof waterproof sheet 13. The base waterproof sheet 15 is the same as the roof waterproof sheet 13.

  Next, the waterproof tape 16 is applied to the end of the raised roof steel sheet 14 and the joint of the base waterproof sheet 15 to perform waterproofing. The waterproof tape 16 is attached in an L shape so as to extend from the upper surface to the side surface of the reinforcing base 10. The waterproof tape 16 shown in this embodiment has a 50 mm width acrylic resin tape stretched thereon, and the same 50 mm width double-sided adhesive butyl tape is pasted thereon.

  Next, a lower steel plate 17 as a steel plate formed in a substantially U-shape with a downward opening from the top of the reinforcing base 10 is covered and covered. The lower steel plate 17 is the same as a general long steel plate roof material, and a plated steel plate having a thickness of 0.35 mm was used in this example. Since the double-sided adhesive butyl tape is attached as the waterproof tape 16 on the reinforcing base 10, it is attached to the reinforcing base 10 in close contact with the adhesive. And several places are fixed on the side of the reinforcing base 10 by sheet metal nails (not shown). The lower end portion of the lower steel plate 17 is folded back to the inside of the reinforcing base 10 for end protection and waterproofing.

  As shown in FIGS. 8 and 9, both ends in the longitudinal direction of the reinforcing base 10 when the lower steel plate 17 is covered are folded and crimped with the ends of the roof steel plate 18 raised on the short side surface of the reinforcing base 10. deep. By using the sheet metal fold 18a, durability can be obtained by minimizing the number of places depending on the sealing material. Similarly, waterproofing is performed with the waterproof tape 16 at the joint between the roof steel sheet 18 and the base waterproof sheet 15 on the reinforcing base 10.

  Next, a sealing material is applied onto the coated lower steel sheet 17 as an adhesive fixing means, and an upper steel sheet 19 as a steel sheet is coated thereon. The upper steel plate 19 is a thin steel plate formed into a substantially U-shape with a downward opening similar to the lower steel plate 17, and a 0.6 mm steel plate was used in this example. The processing of the end portion in the longitudinal direction of the upper steel plate 19 is folded over the folding 18a of the lower steel plate 17.

  Next, installation of the solar cell module 30 and the gantry 31 on the reinforcing base 10 installed as described above will be described.

  The reinforced base 10 is provided with gantry fixing brackets 32 that are mounted at two or more locations in the longitudinal direction, or at more locations. The gantry fixing bracket 32 is formed by bending a steel plate.The gantry fixing bracket 32 has a substantially rectangular horizontal portion 32a on the reinforcing base 10 in plan view and the opposite sides of the horizontal portion 32a in plan view facing downward and upward, respectively. A pair of bent downward vertical pieces 32b and upward vertical pieces 32c are provided.

  The base fixing bracket 32 is placed on the top surface of the reinforcing base 10 at the horizontal portion 32a, the downward vertical piece 32b is positioned so as to sandwich the longitudinal side surface of the reinforcing base 10, and a plurality of lateral fixing holes are provided in the downward vertical piece 32b to fix it. The gantry fixing bracket 32 is fixed to the reinforcing base 10 with screws or the like whose holes are waterproofed from the horizontal direction.

  The upward vertical piece 32b of the gantry fixing bracket 32 is raised upward from the upper surface of the reinforcing base 10, and the downward vertical piece 32b and the upward vertical piece 32c are set to be orthogonal in a plan view.

  Front and rear gantry beams 33 connected to the respective gantry fixing brackets 32 of the plurality of reinforced bases 10 are provided, and the direction of the gantry beams 33 perpendicular to the reinforced base 10 is the longitudinal direction. The gantry beam 33 is a substantially U-shaped beam member having a downward opening and a thin steel plate. The gantry beam 33 is fixed so as to fit between the upward vertical pieces 32c of the gantry fixing bracket 32 from above.

  Here, the front side is a substantially south side where the solar cell module 30 faces the sun, and the rear side is a substantially north side opposite thereto. A short frame front leg 34 is erected on the front frame beam 33, and a long frame rear leg 35 is erected on the rear frame beam 33. The gantry front leg 34 and the gantry rear leg 35 are made of U-shaped steel plates in plan view, and the lower ends thereof are fixed to the gantry beam 33.

  An inclined frame beam 36 is provided between the tops of the frame front legs 34 and the frame rear legs 35. The frame inclined beam 36 is made of a U-shaped steel plate having a downward opening, and both ends thereof are fixed to the tops of the frame front leg 34 and the frame rear leg 35. In the embodiment, the distance from the upper surface of the reinforced base to the upper end of the gantry front leg 34 and the gantry rear leg 35 is about 600 mm and about 1200 mm, the distance between the gantry front leg 34 and the gantry rear leg 35 is about 1365 mm, and the tilt angle of the gantry inclined beam 36 is horizontal. It shows about 30 degrees.

  A plurality of solar cell modules 30 are attached to the gantry inclined beam 36. In the example, eight solar cell modules 30 having a size of 808 mm × 1580 mm are arranged in two rows and four rows. These will be added as appropriate depending on the size of the roof to be installed.

  By installing the solar cell module 30 and the base 31 on the roof 1 with the reinforcing base 10 as the base as described above, the load due to weight and wind can be distributed over the installation length of the reinforcing base 10, so that the existing building This greatly increases the possibility of installation and contributes to the spread of solar cell modules. Moreover, since the installation of the reinforcing base 10 increases the strength of the roof itself, an improvement in earthquake resistance can also be expected.

  In the present embodiment, wind loads and vibrations acting on the solar cell module 30 are transmitted to the reinforcing base 10 through screws or the like that fix the downward vertical piece 32b of the gantry fixing bracket 32. However, since the reinforcing base 10 under the base fixing bracket 32 is covered with high strength by the double steel plates 17 and 19, the steel plate is not torn from the hole portion such as a screw, and is highly durable and waterproof. It becomes an installation structure.

  In addition, even in the base for covering the reinforcing base 10 with the double steel plates 17 and 19, unnecessary seams are generated on the upper surface of the roof 1 by using the above-described waterproof sheet, roof steel plate 14, etc. The installation structure is highly waterproof.

  The present invention described above is not limited to the above-described embodiment, and various modifications can be made within the scope of the gist. For example, an example in which the base reinforcement 10 is fixed to the rafter 3 or the main purlin 2 below the rafter 3 in a building using a wooden frame construction method has been shown, but it may be fixed to the structural material under the base plate with screws or the like. You may make it fix to the truss material etc. of a roof.

  Further, although an example in which the gantry fixing bracket 32 is used for fixing the gantry 31 on the reinforced base 10 is shown, the fixing structure to the reinforced base 10 is not limited to this, and an L-shaped fixing member is used as the reinforced base 10. It may be attached to the upper surface of the frame, and a frame or the like may be constructed thereon.

  In addition, an example is shown in which the lower steel plate 17 that covers the reinforcement base 10 is coated with 0.35 mm and the upper steel plate 19 is coated with 0.6 mm. This is a low cost of 0.35 mm steel plate and doubles about 1 mm thick. This is because there is a merit that the strength can be obtained. However, the thickness is not limited to this, and both thicknesses may be 0.6 mm.
