Description

本発明は、屋根構造に関する。   The present invention relates to a roof structure.

建造物の野地板上にスレート等の屋根材が設けられた屋根構造が知られている（例えば特許文献１参照）。この屋根構造では、野地板と屋根材との間の通気性が良くなく、太陽光発電パネルが設置される場合、発電性能が低下してしまうという問題がある。そこで、凸部と凹部とを軒方向に交互に有する凹凸屋根パネルを用い、この凹凸屋根パネルを野地板上に設置して、凸部と野地板との間に通気空間を形成することが考えられている。   A roof structure in which a roof material such as a slate is provided on a field plate of a building is known (see, for example, Patent Document 1). In this roof structure, there is a problem that the air permeability between the field board and the roofing material is not good, and when the photovoltaic power generation panel is installed, the power generation performance is deteriorated. Therefore, it is considered to use an uneven roof panel having convex portions and concave portions alternately in the eave direction, and to install the uneven roof panel on the base plate to form a ventilation space between the convex portion and the base plate. It has been.

これは、図４に示すように、野地板１の軒側の端部上に固定部材５が載置されて固定され、この固定部材に対して凹凸屋根パネル２が固定されるものが考えられている。図中の符号２０は通気空間を、２５は凹凸屋根パネルの凹部を、２４は凹凸屋根パネルの凸部を、５１は固定部材に設けられる面戸を、５２は固定部材の先端に設けられる水切りを示す。   As shown in FIG. 4, the fixing member 5 is placed and fixed on the end portion of the eaves side of the field board 1 and the uneven roof panel 2 is fixed to the fixing member. ing. In the figure, reference numeral 20 is a ventilation space, 25 is a concave portion of the concave and convex roof panel, 24 is a convex portion of the concave and convex roof panel, 51 is a face door provided on the fixing member, and 52 is a drainer provided at the tip of the fixing member. Indicates.

固定部材５は、その挿通孔５３を介して野地板１に固着具（不図示）が打ち込まれることで、野地板１に固定される。凹凸屋根パネル２は、凹部２５の底片２３から軒側に向けて延出片６が連設されている。この凹凸屋根パネル２は、野地板１上に載置されて、図４、延出片６が固定部材５の水切り５３を巻き込むように折り曲げられて、固定部材５に対して固定される。これにより、凹凸屋根パネル２は固定部材５を介して野地板１に固定されるものである。   The fixing member 5 is fixed to the field board 1 by driving a fixing tool (not shown) into the field board 1 through the insertion hole 53. In the uneven roof panel 2, extended pieces 6 are continuously provided from the bottom piece 23 of the concave portion 25 toward the eaves side. The uneven roof panel 2 is placed on the base plate 1, and the extension piece 6 is bent so that the draining piece 53 of the fixing member 5 is wound around and fixed to the fixing member 5. Thereby, the uneven roof panel 2 is fixed to the base plate 1 via the fixing member 5.

しかしながら、図４に示す従来例にあっては、凹凸屋根パネル２を野地板１に固定するにあたり、作業者は、凹部２５毎に形成されている延出片６を、固定部材５を巻き込むようにして折り曲げる必要があり、この作業が面倒で手間と時間がかかるものとなっていた。   However, in the conventional example shown in FIG. 4, when fixing the uneven roof panel 2 to the base plate 1, an operator seems to entrain the extending member 6 formed for each recess 25 with the fixing member 5. Therefore, this work is troublesome and takes time and effort.

また、凸部２５は、固定部材５や野地板１に直接固定されていないため、凸部２５が上方に浮き上がる惧れがあるものであった。   Moreover, since the convex part 25 is not being directly fixed to the fixing member 5 or the field plate 1, the convex part 25 may be lifted upward.

本発明は前記問題点に鑑みて発明したものであって、その目的とするところは、野地板への固定がし易く、軒側の端部が浮き上がるのを抑える屋根構造を提供することにある。   This invention is invented in view of the said problem, The place made into the objective is to provide the roof structure which is easy to fix to a field board and suppresses the edge part of an eaves side floating. .

以下、本発明を図１乃至図３に示す実施形態に基いて説明する。本発明においては、図１に示すように、野地板１の上面に凹凸屋根パネル２が設けられて、屋根が構成される。   Hereinafter, the present invention will be described based on the embodiment shown in FIGS. In this invention, as shown in FIG. 1, the uneven roof panel 2 is provided in the upper surface of the field board 1, and a roof is comprised.

野地板１は、ボルトや釘が打ち込み可能な材質（主に木材）からなるもので、本実施形態では、軒棟方向Ｄ１に単調に傾斜して配置されている。   The field board 1 is made of a material (mainly wood) into which bolts and nails can be driven, and in the present embodiment, the field board 1 is disposed so as to be inclined monotonously in the eaves-ridge direction D1.

凹凸屋根パネル２は、図２に示すように、金属製の板材からなるもので、本実施形態では、平板状をしたガルバニウム鋼板が屈曲されて構成される。凹凸屋根パネル２は、上片２１と、上片２１の軒方向Ｄ２の両側端部から下方に連設される側片２２と、側片２２の下端部から軒方向Ｄ２に連設される底片２３とを備えている。上片２１と側片２２と底片２３はそれぞれ平板状をしているが、厳密な平板状でなくてもよい。また、各上片２１は同一平面上に位置し、各底片２３も同一平面上に位置しているが、厳密な同一平面上に位置していなくてもよい。   As shown in FIG. 2, the uneven roof panel 2 is made of a metal plate material, and in the present embodiment, a flat galvanium steel plate is bent and configured. The uneven roof panel 2 includes an upper piece 21, a side piece 22 provided downward from both side ends of the eave direction D 2 of the upper piece 21, and a bottom piece provided continuously from the lower end of the side piece 22 in the eave direction D 2. 23. The upper piece 21, the side piece 22, and the bottom piece 23 each have a flat plate shape, but may not have a strict flat plate shape. Moreover, although each top piece 21 is located on the same plane and each bottom piece 23 is also located on the same plane, it does not need to be located on the exact same plane.

上片２１とその軒方向Ｄ２の両側の側片２２とで凸部２４が構成され、底片２３とその軒方向Ｄ２の両側の側片２２とで凹部２５が構成され、凸部２４と凹部２５とが軒方向Ｄ２に交互に形成されている。そして、凸部２４の内部空間が通気空間２０となる。すなわち、凹凸屋根パネル２上に太陽光発電パネル（不図示）が設置される場合があるが、この場合、通気空間が設けられていることで、太陽光発電パネルの冷却が促進され、発電性能が低下するのを抑えることができる。太陽光発電パネルは、太陽光発電素子を備えたパネル本体と、パネル本体を収納するフレームまたはケーシングからなる収納体と、を備えるもので、多くの製品が広く知られていて、特に限定されず、様々な太陽光発電パネルが適宜利用可能である。   The upper piece 21 and the side pieces 22 on both sides in the eave direction D2 constitute a convex portion 24, and the bottom piece 23 and the side pieces 22 on both sides in the eave direction D2 constitute a concave portion 25. The convex portion 24 and the concave portion 25 Are alternately formed in the eaves direction D2. And the internal space of the convex part 24 becomes the ventilation space 20. That is, although a photovoltaic power generation panel (not shown) may be installed on the uneven roof panel 2, the cooling of the photovoltaic power generation panel is promoted by providing a ventilation space in this case, and the power generation performance. Can be suppressed. A photovoltaic power generation panel includes a panel body provided with a photovoltaic power generation element and a housing body made of a frame or casing for housing the panel body, and many products are widely known and are not particularly limited. Various solar power generation panels can be used as appropriate.

凹凸屋根パネル２の軒側（軒棟方向Ｄ１の建物から離れる側で、図１（ａ）、図２、図３における手前側）の端部には、先端部材３が設けられる。先端部材３は、図３に示すように、上覆い片３１と、側覆い片３２と、下覆い片３３と、導水片３４と、を備えるものである。上覆い片３１は、本実施形態では、軒方向Ｄ２の長さが凹凸屋根パネル２の上片２１の軒方向Ｄ２の長さと略同じ（正確には上片２１より若干長い）となるように形成されている。上覆い片３１の軒方向Ｄ２の両側端部から下方に向けてそれぞれ、側覆い片３２が連設されている。側覆い片３２、本実施形態では、上下長さが凹凸屋根パネル２の側片２２の上下長さと略同じとなるように形成されている。側覆い片３２の下端部から軒方向Ｄ２に向けてそれぞれ、下覆い片３３が連設されている。下覆い片３３は、本実施形態では、軒方向Ｄ２の長さが凹凸屋根パネル２の底片２３の軒方向Ｄ２の長さよりも短く形成されているが、底片２３の軒方向Ｄ２の長さと略同じ（正確には底片２３より若干短い）に形成されてもよい。上覆い片３１と側覆い片３２と下覆い片３３の正面視形状は、凹凸屋根パネル２の正面視形状と略同じとなっている。そして、凹凸屋根パネル２と同様に、上覆い片３１とその両側の側覆い片３２とで構成される凸部と、下覆い片３３とその両側の側覆い片３２とで構成される凹部とが軒方向Ｄ２に多数並設されている。   A tip member 3 is provided at an end of the eaves side of the uneven roof panel 2 (on the side away from the building in the eave building direction D1, on the front side in FIGS. 1A, 2 and 3). As shown in FIG. 3, the tip member 3 includes an upper covering piece 31, a side covering piece 32, a lower covering piece 33, and a water guiding piece 34. In the present embodiment, the length of the eave direction D2 of the upper cover piece 31 is substantially the same as the length of the eave direction D2 of the upper piece 21 of the uneven roof panel 2 (more precisely, slightly longer than the upper piece 21). Is formed. Side cover pieces 32 are continuously provided from both end portions in the eave direction D2 of the upper cover piece 31 downward. The side cover piece 32, in this embodiment, is formed so that the vertical length is substantially the same as the vertical length of the side piece 22 of the uneven roof panel 2. A lower covering piece 33 is continuously provided from the lower end portion of the side covering piece 32 toward the eave direction D2. In the present embodiment, the length of the eave direction D2 is shorter than the length of the eave direction D2 of the bottom piece 23 of the uneven roof panel 2, but the lower cover piece 33 is substantially the same as the length of the eave direction D2 of the bottom piece 23. It may be formed in the same (exactly slightly shorter than the bottom piece 23). The front view shape of the upper cover piece 31, the side cover piece 32, and the lower cover piece 33 is substantially the same as the front view shape of the uneven roof panel 2. And like the uneven roof panel 2, the convex part comprised by the upper cover piece 31 and the side cover piece 32 of the both sides, and the recessed part comprised by the lower cover piece 33 and the side cover pieces 32 of the both sides, Are arranged in parallel in the eaves direction D2.

上覆い片３１および下覆い片３３の軒側の端部から、軒側に向けて、導水片３４が突出されている。導水片３４は、上覆い片３１および下覆い片３３に対して、軒側の斜め下方に向けて鈍角をなすように形成される。下覆い片３３の軒側の端部は、上覆い片３１の軒側の端部よりも軒側に位置しており、側覆い片３２の軒側の端部は、下側へ行く程、軒側へ位置するように傾斜している。導水片３４の棟側（軒側の反対側）端部は、上覆い片３１と側覆い片３２と下覆い片３３の軒側の端部と接続されている。上覆い片３１および下覆い片３３と導水片３４との間の角度は、１２０°〜１５０°が好ましく、本実施形態では１５０°である。   A water guide piece 34 protrudes from the eaves side end of the upper cover piece 31 and the lower cover piece 33 toward the eave side. The water guide piece 34 is formed so as to form an obtuse angle with respect to the upper cover piece 31 and the lower cover piece 33 obliquely downward on the eaves side. The end of the eaves side of the lower covering piece 33 is located on the eaves side than the end of the eaves side of the upper covering piece 31, and the end of the eaves side of the side covering piece 32 is closer to the lower side. It is inclined to be located on the eaves side. The ridge side (opposite side of the eaves side) end of the water guide piece 34 is connected to the eaves side ends of the upper covering piece 31, the side covering piece 32 and the lower covering piece 33. The angle between the upper cover piece 31 and the lower cover piece 33 and the water guide piece 34 is preferably 120 ° to 150 °, and 150 ° in this embodiment.

導水片３４の先端部は、図１（ｂ）に示すように、下方に折曲されており、端面が露出することによる見栄えの低下およびエッジの形成が回避される。   As shown in FIG. 1B, the tip of the water guide piece 34 is bent downward, so that the appearance and edge formation due to exposure of the end face are avoided.

凹凸屋根パネル２の野地板１への取り付けについて説明する。   The attachment of the uneven roof panel 2 to the base plate 1 will be described.

図１に示すように、凹凸屋根パネル２は、野地板１上の所定の位置に載置される。本実施形態では、図１（ｂ）に示すように、凹凸屋根パネル２の軒側の端部は、野地板１の軒側の端部よりも軒側に突出しており、突出した部分が出代部２６となっている。この出代部２６の凸部２５内の通気空間が下方に開放されることで、通気空間が大気と連通し、通気による太陽光発電パネルの冷却を可能としている。   As shown in FIG. 1, the uneven roof panel 2 is placed at a predetermined position on the field board 1. In this embodiment, as shown in FIG.1 (b), the edge part of the eaves side of the uneven roof panel 2 protrudes in the eaves side rather than the edge part of the eaves side of the field board 1, and the protruding part protrudes. It is a surrogate 26. Since the ventilation space in the convex portion 25 of the protruding portion 26 is opened downward, the ventilation space communicates with the atmosphere, and cooling of the photovoltaic power generation panel by ventilation is possible.

野地板１上の所定の位置に載置された凹凸屋根パネル２に、先端部材３が上方より覆い被せられる。この時、上覆い片３１が上片２１の上面を覆い、側覆い片３２が側片２２を覆い、下覆い片３３が底片２３の上面を覆うように装着される。本実施形態では、図１（ｂ）に示すように、先端部材３の上片２１の軒側の端部は、凹凸屋根パネル２の軒側の端部よりも軒側に位置しているが、凹凸屋根パネル２の軒側の端部と軒棟方向Ｄ１において同じ位置であってもよい。導水片３４の出代、すなわち、先端部材３の凹凸屋根パネル２に対する軒棟方向Ｄ１の位置は、軒樋（不図示）が設けられる位置に応じて、適宜調節可能である。   The tip member 3 is covered from above on the uneven roof panel 2 placed at a predetermined position on the field board 1. At this time, the upper cover piece 31 is mounted so as to cover the upper surface of the upper piece 21, the side cover piece 32 covers the side piece 22, and the lower cover piece 33 covers the upper surface of the bottom piece 23. In the present embodiment, as shown in FIG. 1B, the eaves-side end of the upper piece 21 of the tip member 3 is located on the eaves side of the eaves-side end of the uneven roof panel 2. Moreover, the same position may be sufficient in the eaves-side edge part of the uneven roof panel 2, and the eaves building direction D1. The allowance of the water guide piece 34, that is, the position of the eave building direction D1 with respect to the uneven roof panel 2 of the tip member 3 can be adjusted as appropriate according to the position where the eaves ridge (not shown) is provided.

そして、凹凸屋根パネル２に装着された先端部材３の上方より、固着具４が先端部材３および凹凸屋根パネル２を介して野地板１に打ち込まれる。本実施形態の固着具４は、図１（ｂ）に示すように、頭部４１の軸部４２側にパッキン４３を備えたパッキン付きビスである。なお、固着具４として、釘、パッキン付きビスではないビス、ボルトが用いられてもよいし、他の部材も適宜利用可能である。   Then, the fixing tool 4 is driven into the base plate 1 via the tip member 3 and the rugged roof panel 2 from above the tip member 3 attached to the rugged roof panel 2. The fixing tool 4 of this embodiment is a screw with packing provided with a packing 43 on the shaft portion 42 side of the head 41 as shown in FIG. As the fixing tool 4, a nail, a screw other than a screw with packing, and a bolt may be used, and other members may be used as appropriate.

本実施形態では、図１に示すように、固着具４が、先端部材２の上覆い片２１および凹凸屋根パネル２の上片２１を介して野地板１に打ち込まれている。なお、図１（ａ）の一点鎖線で示すように、固着具４が、先端部材２の下覆い片２３および凹凸屋根パネル２の底片２３を介して野地板１に打ち込まれてもよい。   In the present embodiment, as shown in FIG. 1, the fixing tool 4 is driven into the field board 1 via the upper cover piece 21 of the tip member 2 and the upper piece 21 of the uneven roof panel 2. In addition, as shown with the dashed-dotted line of Fig.1 (a), the fixing tool 4 may be driven into the baseplate 1 through the lower covering piece 23 of the front-end | tip member 2, and the bottom piece 23 of the uneven | corrugated roof panel 2. FIG.

本発明にあっては、凹凸屋根パネル２の野地板１への固定は、野地板１上に載置された凹凸屋根パネル２に先端部材３が装着され、固着具４が先端部材３および凹凸屋根パネル２を介して野地板１に打ち込まれることで行われる。このため、図４に示す従来例のように、凹凸屋根パネル２の凹部２５毎に形成されている延出片６を、固定部材５に巻き付けるようにして取り付ける必要がない。従って、従来例よりも作業の手間と時間が省かれるものである。   In the present invention, the uneven roof panel 2 is fixed to the base plate 1 by attaching the tip member 3 to the uneven roof panel 2 placed on the base plate 1, and the fixture 4 is connected to the tip member 3 and the uneven plate. This is done by driving into the field board 1 through the roof panel 2. Therefore, unlike the conventional example shown in FIG. 4, it is not necessary to attach the extending piece 6 formed for each concave portion 25 of the uneven roof panel 2 so as to be wound around the fixing member 5. Therefore, labor and time can be saved compared with the conventional example.

また、上覆い片３１が上片２１の上面を覆い、下覆い片３３が底片２３の上面を覆っており、上片２１や底片２３に上方へ浮き上がる方向に力がかかっても、上覆い片３１や下覆い片３３に押さえられる。このように、凹凸屋根パネル２の凸部２４と凹部２５の軒側の端部が両方とも、先端部材２により押さえられて、凹凸屋根パネル２の軒側の端部が浮き上がり難くなるものである。   The upper covering piece 31 covers the upper surface of the upper piece 21, and the lower covering piece 33 covers the upper surface of the bottom piece 23. Even if a force is applied to the upper piece 21 or the bottom piece 23 in the upward direction, the upper covering piece 31 is covered. 31 and the lower covering piece 33. In this way, both the eaves side end portions of the convex portion 24 and the concave portion 25 of the uneven roof panel 2 are pressed by the tip member 2, and the eave side end portion of the uneven roof panel 2 is difficult to lift. .

また、従来例にあっては、上片２１上や底片２３上を勢い良く流下してきた雨水は、上片２１や底片２３に対して略垂直に垂下する水切り５２を流下せず、上片２１や底片２３の軒側の端部より飛び出して、軒樋内にうまく流れ込まない惧れがあった。   Further, in the conventional example, the rainwater that has flowed down on the upper piece 21 and the bottom piece 23 does not flow down the drainer 52 that hangs substantially perpendicular to the upper piece 21 and the bottom piece 23, and the upper piece 21. There was a possibility that it would jump out from the end of the eaves side of the bottom piece 23 and not flow into the eaves well.

これに対し本実施形態においては、導水片３４が、上覆い片３１および下覆い片３３に対して軒側の斜め下方に鈍角をなすように形成されている。このため、凹凸屋根パネル２の上片２１から上覆い片３１にかけて流下し、底片２３から下覆い片３３にかけて流下する雨水は、勢い良く流下してきても、導水片３４に乗り移って導水片３４上を流れ易くなる。これにより、雨水が上覆い片３１や下覆い片３３の軒側の端部より飛び出して、軒樋内にうまく流れ込まないといったことを起こり難くすることができる。   On the other hand, in this embodiment, the water guide piece 34 is formed so as to form an obtuse angle obliquely downward on the eaves side with respect to the upper cover piece 31 and the lower cover piece 33. For this reason, the rainwater that flows down from the upper piece 21 to the upper covering piece 31 of the uneven roof panel 2 and flows down from the bottom piece 23 to the lower covering piece 33 is transferred to the water guiding piece 34 on the water guiding piece 34 even if it flows down vigorously. It becomes easy to flow. Thereby, it can be made hard to happen that rain water jumps out from the edge part of the eaves side of the upper covering piece 31 and the lower covering piece 33, and does not flow into the eaves well.
