Description

  The present invention relates to a tile for mounting a rooftop installation on a tiled roof and a rooftop installation structure using the tile.

  Currently, solar power generation systems, solar heat collection systems, and the like are in widespread use as a mechanism for using clean energy. With regard to such a system, for example, in the case of a photovoltaic power generation system, it is realized by installing a solar cell module on a roof of a house or the like, and converting solar energy into electric energy through the solar cell module. The Such a system is effective as a measure for preventing global warming by reducing carbon dioxide, and is expected to be widely used in the future.

  As a method of installing the solar cell module on the roof, one end of a predetermined support bracket is attached to a field plate or rafter through roof materials such as tiles and sheet metal, and a mounting structure called a rack system is attached to the other end of the support bracket Is often used, and a solar cell module is attached to this structure.

  Specifically, an L-shaped support bracket substrate is inserted between the existing tiles that overlap in the eaves direction and attached to the roof tiles, field boards, piers, etc., and vertical rails are attached to the legs of the support brackets. A method of connecting the members, fixing the horizontal rail member between the plurality of vertical rail members, and fixing the solar cell module to the horizontal rail member is employed.

  However, when this attachment method is performed using a conventional roof tile, the support roof substrate is inserted between the roof tile and the roof tile, so that the upper roof tile rises by the thickness of the substrate. A gap corresponding to the thickness of the substrate is generated between the upper roof tile and the lower roof tile. As a result, there has been a problem that rainwater or the like enters through this gap to cause rain leakage. Furthermore, such a gap becomes larger with the passage of years due to wind and rain, and there is a problem that the risk of rain leakage increases along with it.

  On the other hand, as a solar cell module mounting structure capable of preventing such rain leakage, a solar cell roofing structure on an existing roof (see Japanese Patent Laid-Open No. 2003-314010) has been proposed. However, in such a solar cell roofing structure on an existing roof, it is necessary to cover the surface of the roof tile with a waterproof sheet and to dispose a predetermined spacer on the waterproof sheet. Therefore, such an attachment structure increases the number of parts for attaching the solar cell module, and increases the burden on cost, resources, work, and the like.

  Therefore, it is desirable that the mounting structure for the rooftop installation such as a solar cell module is an inexpensive structure and can effectively prevent rain leakage without increasing the number of parts. However, there are currently no rooftop installation roof tiles and mounting structures such as solar cell modules that satisfy such requirements.

  The present invention has been made in view of these inconveniences, and aims to provide a rooftop installation tile and a mounting structure that are excellent in low cost and easy installation, and can effectively prevent rain leakage. To do.

The idea made to solve the above problems is
A tile for attaching a rooftop installation to a tiled roof,
The roof tile has a metal fitting insertion groove on the eaves side and the back side of the roof body.

  The roof tile can be mounted by fitting the support bracket into the bracket insertion groove when mounting the rooftop installation object using the support bracket. As a result, according to the roof tile, even when the support metal fitting is attached, no lifting corresponding to the thickness of the support metal fitting occurs between the overlapping roof tiles and the roof tile. Therefore, the tile can suppress rainwater and the like from entering the back side of the tile, and can effectively prevent rain leakage from the attic. Further, according to the roof tile, it is possible to prevent rain leakage without using a special member, so that the cost can be significantly reduced. In addition, according to the roof tile, since a special work for preventing rain leakage is omitted, the work time can be shortened.

  The depth of the metal fitting insertion groove is preferably 0.1 cm or more and 0.6 cm or less. Thereby, while raising of a roof tile can be prevented, the clearance gap produced between a metal fitting insertion groove and a support metal fitting can be made small. As a result, the roof tile can suppress rainwater from entering between the metal fitting insertion groove and the support metal, and can further enhance the waterproof effect.

  It is good to have a fixing through-hole on the ridge side and on the eaves ridge direction line passing through the center of the metal fitting insertion groove. Thereby, a screw can be screwed in from this fixing through hole, and the roof tile disposed below the roof tile, the support fitting, and the roof tile can be fixed. As a result, according to the roof tile, the support fitting can be firmly fixed, and the stability of the rooftop installation can be improved.

  Accordingly, in a mounting structure for a rooftop installation object in which a support bracket is sandwiched between a pair of tiles that overlap in the direction of the eaves and the rooftop installation object is attached via the support bracket, the support bracket is fitted in the bracket insertion groove of the roof tile. According to the rooftop object mounting structure that fixes the support fitting in a combined state, there is no lifting corresponding to the thickness of the support fitting between the overlapping tiles. Therefore, the said roof installation thing attachment structure can suppress that rainwater etc. permeate into the back side of a roof tile, and can prevent effectively the rain leak from an attic as a result. Moreover, according to the said roof installation thing attachment structure, since it can prevent rain leak even if it does not depend on a special member, cost can be reduced significantly. In addition, according to the rooftop installation structure, the special work for preventing rain leakage is omitted, so the work time can be shortened.

  As explained above, the rooftop installation tile and the mounting structure of the present invention can install a rooftop installation at a low cost without increasing the number of parts, and can effectively prevent rain leakage.

It is a perspective view which shows the roof tile which concerns on one Embodiment of this invention. It is typical sectional drawing which shows the attachment structure of the roof tile of FIG. It is a perspective view which shows the roof tile which concerns on a different form from the roof tile of FIG. It is typical sectional drawing which shows the attachment structure of the roof tile of FIG.

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

  The roof tile 1 of FIG. 1 has a roof body 2, side edge portions 3, and a bottom portion 4.

  The material of the tile 1 is not particularly limited, but in general, ceramic materials such as clay, hydraulic inorganic materials such as cement and plaster, metals such as stainless steel, aluminum and copper, fiber reinforced plastic (FRP), polycarbonate , Synthetic resins such as acrylic resins, or mixtures thereof can be used.

  The roof tile body 2 has a metal fitting insertion groove 5.

  The metal fitting insertion groove 5 is formed on the eaves side and the back side of the roof tile body 2. Specifically, the metal fitting insertion groove 5 is formed at the lower end and the center of the forward hanging of the roof tile body 2. The metal fitting insertion groove 5 is formed in a substantially rectangular cross section in a plane perpendicular to the eaves-ridge direction.

  The size of the metal fitting insertion groove 5 is not particularly limited. The depth of the metal fitting insertion groove 5 is preferably 0.1 cm or more and 0.6 cm or less, and more preferably 0.2 cm or more and 0.5 cm or less. When the depth of the metal fitting insertion groove 5 is formed in the above range, even when a support metal fitting (not shown) is inserted into the metal fitting insertion groove 5, it is generated between the metal fitting insertion groove 5 and the support metal fitting. The gap can be reduced. As a result, the roof tile 1 can prevent the roof tile from being lifted, can suppress the intrusion of rainwater from between the metal fitting insertion groove 5 and the support metal fitting, and can further enhance the waterproof effect.

  In addition, the width of the metal fitting insertion groove 5 is not particularly limited as long as it is equal to or larger than the width of the support metal fitting inserted into the metal fitting insertion groove 5, but is generally set to about 1.5 cm to 4.5 cm. By forming the width of the metal fitting insertion groove 5 in the above range, the gap generated by the difference in width between the metal fitting insertion groove 5 and the support metal fitting can be kept small. As a result, the roof tile 1 can suppress the intrusion of rainwater from between the metal fitting insertion groove 5 and the support metal fitting, and can further improve the waterproof effect.

  Next, a method for manufacturing the roof tile 1 will be described. In addition, although the case of the earthenware tile using a clay material is mentioned as an example in the following manufacturing procedures, even when manufacturing with a metal or a synthetic resin, a well-known method can be used by using a mold shown below. Can be manufactured.

  First, as an extrusion molding step (STP1), a predetermined clay raw material is blended, and the moisture-adjusted clay dough is extruded into a molding flat plate with a vacuum extruder. Next, as a press molding step (STP2), a mold having a convex portion for forming the metal fitting insertion groove 5 is attached to a press machine, and the molding flat plate formed by STP1 is press-molded to form the metal fitting insertion groove 5 It forms into the tile-shaped molded object which has. Subsequently, in the drying step (STP3), the molded body is polished with a spatula or the like to prepare the roof surface and then dried. Furthermore, as a firing step (STP4), the roof tile obtained in STP3 is coated with glaze and fired in a firing furnace. The roof tile 1 can be obtained through STP1 to STP4.

  As another method for obtaining the roof tile 1, the metal fitting insertion groove 5 can be formed by scraping the roof tile with a spatula or the like when the roof tile is in a white background after the STP 3.

  Next, with reference to FIG. 2, the procedure for mounting the rooftop installation using the roof tile 1 and the mounting structure will be described.

  First, before installing the roof tile 1, the support fitting 13 is installed on the top surface of the roof tile 11 similar to the roof tile 1 and in the center in the width direction (the center in the width direction of the roof body of the roof tile 11). The support metal fitting 13 is installed on the surface side of the roof tile 11 so as to cover the roof tile 11 from the ridge side and substantially parallel to the eaves ridge direction. The support fitting 13 is connected to the base plate and the rafter by screwing a screw from above with a washer.

  Next, the roof tile 1 is installed so that the eaves side front end of the substrate 14 of the support bracket 13 and the bracket insertion groove 5 of the roof tile 1 are fitted. And the support metal fitting 15 is fixed to the ridge side of the said tile 1 by the method similar to having installed in the roof tile 11. Further, a roof tile 12 similar to the roof tile 1 is installed in the same manner as the roof tile 1.

  Subsequently, the vertical rail member is placed on the top surfaces of the support fitting 13 and the support fitting 15. The support fitting 13 and the support fitting 15 are connected to the vertical rail member by screwing a bolt from below with a washer. The support fitting 13 and the support fitting 15 and the vertical rail member are securely fixed by screwing a nut onto a bolt protruding to the upper surface side of the vertical rail member.

  One vertical rail member is fixed substantially in parallel with the eaves ridge direction by the support fitting 13, the support fitting 15, and the like. In addition, a plurality of vertical rail members are installed approximately parallel to the eaves direction and at substantially equal intervals with other vertical rail members. A plurality of horizontal rail members (not shown) are fixed to the plurality of vertical rail members so as to form a lattice shape, and a rooftop installation (not shown) is installed on the plurality of horizontal rail members. The

  The roof tile 1 can be mounted by fitting these support brackets into the bracket insertion groove 5 when mounting the rooftop installation object using the support bracket 13, the support bracket 15, or the like. As a result, according to the roof tile 1, even when the support bracket 13 and the support bracket 15 are attached, no lifting corresponding to the thickness of the support bracket 13 and the support bracket 15 occurs between the overlapping roof tiles and the roof tile. Therefore, the tile 1 can suppress rainwater and the like from entering the back side through the gap between the tile and the tile, and can effectively prevent rain leakage from the attic. In addition, according to the roof tile 1, rain leakage can be prevented without using a special member, so that the cost can be significantly reduced. In addition, according to the roof tile 1, since a special work for preventing rain leakage can be omitted, the work time can be shortened.

  The roof tile 21 of FIG. 3 includes a roof tile body 2, side edge portions 3, and a bottom portion 22.

  The roof tile body 2 and the side edge 3 are the same as the roof tile 1 of FIG.

  The butt portion 22 has a fixing through hole 23. The bottom portion 22 is integrally connected to the roof tile body 2 on the ridge side of the roof tile body 2. The butt portion 22 is formed in a shape protruding from the roof tile body 2 on the surface side. The butt portion 22 can prevent rainwater from invading from the roof tile body 2 side beyond the butt portion 22 by the raised portion.

  The fixing through-hole 23 is formed on the eave building direction line passing through the building side and the center of the metal fitting insertion groove 5. The fixing through-hole 23 is formed at a position where the roof tile 21 and the pier overlap when the roof tile 21 is installed on the roof.

  With reference to FIG. 4, the roof installation thing attachment procedure and attachment structure using the said roof tile 21 are demonstrated.

  First, before installing the roof tile 21, a roof tile 31 similar to the roof tile 21 is installed. Specifically, the roof tile 31 is installed so that the convex part formed in the ridge side edge part of the roof tile 31 may engage with the ridge side surface of the pier. Subsequently, the support bracket 33 is installed on the upper surface of the roof tile 31 and in the center in the width direction (the center in the width direction of the roof body of the roof tile 31). The support fitting 33 is installed on the roof tile 31 so that the through hole of the substrate 34 and the fixing through hole of the roof tile 31 overlap each other. The support bracket 33 is installed on the roof tile 31 so as to be substantially parallel to the eaves-ridge direction. The support fitting 34 is connected to the roof tile 31 and the pier by inserting a screw from above with a washer.

  Next, the roof tile 21 is installed so that the eaves-side tip of the substrate 34 of the support bracket 33 and the bracket insertion groove 5 of the roof tile 21 are fitted. Then, the support bracket 35 is fixed to the ridge side of the roof tile 21 in the same manner as the support bracket 33 is attached to the roof tile 31. Further, a roof tile 32 similar to the roof tile 21 is installed in the same manner as the roof tile 21.

  Further, the method of fixing the support bracket 34 and the support bracket 35 and the vertical rail member is the same as the method of fixing the support bracket 13 and the support bracket 15 of FIG. 2 and the vertical rail member.

  The roof tile 21 can be screwed in from above the fixing through hole 23 to fix the roof tile 21, the support bracket 35, and the pier arranged below the roof tile 21. As a result, according to the roof tile 21, the support bracket 35 and the relatively thick pier can be firmly fixed, and as a result, the stability of the rooftop installation can be improved.

  In addition, the roof tile of this invention can be implemented in the aspect which gave various change and improvement other than the said aspect. For example, as a form of the roof tile, various roof tiles such as a Japanese roof tile, a western roof tile, an S-shape, and a corrugated wall can be used in addition to a flat roof tile. The roof tile does not necessarily have a side edge portion and a bottom portion. The fixing through hole does not necessarily have to be formed in the bottom. Moreover, the metal fitting insertion groove does not necessarily have to be formed in the central portion in the width direction of the roof tile body.

  As described above, the rooftop installation tile and the mounting structure of the present invention can install a rooftop installation at a low cost without increasing the number of parts, and can effectively prevent rain leakage. Therefore, the roof-mounted roof tile of the present invention can be attached to various devices such as solar cell modules, solar heat collecting devices, display devices, light-emitting devices at the same time as the roof tile installation or after the roof tile installation.
