Description

  The present invention relates to a roof-mounted object support fitting for mounting a roof-mounted object such as a solar cell module on a tiled roof.

  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, 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 installed at the other end of the support bracket And the method of attaching a solar cell module to this structure is often used.

  Specifically, a support metal board formed in a substantially L-shape is installed on the existing sloped slope of the roof tile and attached to a roof tile, field board, pier, etc., and a vertical rail member is attached to the upper end of the leg of the support metal. Are connected, and a horizontal rail member is fixed between a plurality of vertical rail members, and a solar cell module is fixed to the horizontal rail member.

  However, when such a mounting method is performed using a conventional support bracket, the leg portion of the support bracket and the eaves side end portion of the roof tile superimposed on the support bracket are fixed in close contact with each other. Become. As a result, in the case of rain, for example, rain easily enters the back side of the roof tile through the contact portion between the support bracket and the roof tile, causing rain leakage. On the other hand, it is also conceivable to fix the support metal so that the distance between the leg portion and the roof tile is kept constant. However, according to such an attachment method, the length of the substrate is increased, the strength of the support metal fitting is reduced, and the solar cell module cannot be stably attached.

  On the other hand, a solar cell roofing structure (see Japanese Patent Application Laid-Open No. 2003-314010) for an existing roof has been proposed as an attachment structure for preventing such rain leakage. However, such a solar cell roofing structure on an existing roof requires that the surface of the roof be covered with a waterproof sheet, and that a predetermined spacer be disposed 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.

  Accordingly, regarding the mounting of rooftop installations such as solar cell modules, it is desired to develop a mounting member that has an inexpensive structure and has an effective rain leakage prevention function without increasing the number of parts. However, there is currently no mounting member that satisfies such requirements.

  The present invention has been made in view of these inconveniences, and aims to provide a rooftop support bracket that can effectively prevent rain leakage while being excellent in low cost and easy installation. is there.

The idea made to solve the above problems is
A support bracket for attaching a rooftop installation to a tiled roof,
A belt-like substrate that has one or a plurality of fixing through-holes and is inserted and fixed in the eaves-ridge direction between a pair of superimposed tiles;
Legs suspended from the eaves side of this board,
The installation object mounting part formed at the upper end of this leg part,
A roof-mounted object support metal fitting characterized in that a ridge side surface of the leg portion is inclined with respect to an eave ridge direction and a vertical plane.

  As for the said support metal fitting, the ridge side surface of a leg part inclines on the basis of a plane perpendicular to the eaves ridge direction. Therefore, the support metal fitting can reduce the contact area between the leg portion and the roof tile without depending on the length of the substrate. Therefore, the support bracket has high strength, can stably fix the rooftop installation, and effectively drains rainwater by using the inclination of the legs even in rainy weather. be able to. Thus, since the said support metal fitting can acquire the high drainage effect because a leg part has a predetermined inclination, it does not require a special member for rain leak prevention, and can control a number of parts. it can. Moreover, the said support metal fitting can suppress manufacturing cost by suppression of a number of parts. Furthermore, since the said support metal fitting does not require the special operation | work for rain leak prevention when attaching a rooftop installation thing, it is excellent also in work efficiency.

  The inclination angle of the ridge side surface of the leg portion may be 20 ° or more and 90 ° or less with respect to the eaves ridge direction and a vertical plane. Thereby, drainage can be further improved.

  The said leg part is good to have V-shaped cross-sectional shape which turned the corner | angular part to the ridge side. Thereby, the area | region where a leg part and a roof contact | abut can be limited, and a rain leak prevention function can be improved. Moreover, the said support metal fittings can drain rain water etc. effectively from the left-right direction using both V-shaped both ends. Compared to the case where the legs are formed in a flat plate shape due to the cross-sectional shape of the legs being refracted, the support bracket is stronger in the eaves direction and in the left-right direction (the direction perpendicular to the eaves direction). Can be increased. As a result, the said support metal fitting can improve the stability of the rooftop installation thing in an attachment state.

  The leg portion may have a semi-cylindrical cross-sectional shape curved toward the ridge side. Thereby, the intensity | strength with respect to the eaves-ridge direction and the left-right direction can further be raised, and stability of the rooftop installation thing in an attachment state can be further improved further.

  The said leg part is good to have the strip | belt-shaped board | plate material which orient | assigned the width direction to the eaves-ridge direction. Thereby, drainage efficiency can be improved remarkably.

  As explained above, the rooftop support bracket of the present invention does not increase the number of parts, and can install the rooftop installation at a low cost, and can effectively prevent rain leakage from the back of the tile. it can.

As shown in FIG. 2, the vertical length of the fixing portion 6 is adjusted to match the height of the pier 11 and the roof tile 14 stacked on the pier 11 in order to securely fix the fixing portion 6 and the base plate 12. It is the same as or less than the height. When the vertical length of the fixing part 6 is shorter than the height of the crosspiece 11 and the roof tile 14, the support metal fitting 1 is interposed via a plate (not shown) having a predetermined thickness under the fixing part 6. It can be suitably attached. The length of the fixed portion 6 in the eaves direction is not particularly limited.

  Although it does not specifically limit as a material of the board | substrate 2, For example, metals, such as an aluminum alloy, stainless steel, copper, a copper alloy, are used. Among these, stainless steel is preferable as the metal forming the substrate 2. Since stainless steel has high strength and is excellent in rust resistance, corrosion resistance, etc., it can stably hold a rooftop installation to be attached for a long period of time.

  The leg 3 is suspended from the eaves side of the substrate 2. The leg part 3 is inclined with respect to the eaves ridge direction and a vertical plane with respect to the ridge side. The width and thickness of the leg 3 are generally the same as those of the substrate 2. The leg 3 is formed of the same material as the substrate 2.
