Japanese Patent Laid-Open No. 11-44060

本発明は、軒樋を接続する継手の前面板を伝って雨水が下方に落下しにくい軒樋の継手装置を提供することにある。 An object of the present invention is to provide a joint device for eaves ridges in which rainwater is unlikely to drop down along the front plate of the joint connecting the eaves ridges.

本発明者は、前記課題を達成するため鋭意検討した結果、継手の前面板を上下に２分割して継手凹溝をなくして、分割空間を形成することによって、その分割空間から軒樋の凹溝へ雨水が入りやすいことを見出し、本発明を完成した。 As a result of diligent study to achieve the above-mentioned problems, the present inventor has divided the front plate of the joint into two parts in the vertical direction to eliminate the joint concave groove and form a divided space. The present invention has been completed by finding that rainwater can easily enter the groove.

即ち、本発明は、屋外側に位置する軒樋の前壁板にその長手方向に亙って内方に凹没させた凹溝を設けてその凹溝に導水孔を配設した軒樋を、長手方向の端部を対向させて配置すると共に、対向する軒樋同士の間に配置した継手の左右端部の内面にそれぞれ軒樋の外面を沿わせて接続させたことで軒樋を接続した軒樋の継手装置において、前壁板の外面に沿わせる継手の前面板を上下に２分割して分割空間を形成し、前記２分割して形成した上部板と下部板とを上下に間隔を隔てて爪嵌合片で連結し、継手内に挿入した軒樋の長手方向の端部を爪嵌合片で係止させて、分割空間を軒樋の凹溝に重ねて位置させた軒樋の継手装置ある。さらに、前記下部板の屋外側上端に雨だれ防止片を突設することが好ましい。 That is, the present invention provides an eave ridge having a concave groove recessed inward in the longitudinal direction on the front wall plate of the eave ridge located on the outdoor side, and a water guide hole disposed in the concave groove. In addition to arranging the ends in the longitudinal direction to face each other, the eaves are connected by connecting the outer surfaces of the eaves along the inner surfaces of the left and right ends of the joints arranged between the opposing eaves In the eaves-joint joint device, the front plate of the joint extending along the outer surface of the front wall plate is vertically divided into two to form a divided space, and the upper and lower plates formed by the two divisions are vertically spaced from each other. Eaves that are connected with claw-fitting pieces with a gap between them and the longitudinal ends of the eaves ridges inserted into the joint are locked with the claw-fitting pieces, and the divided space is positioned so as to overlap the concave grooves of the eaves ridges. There is a spear joint device. Furthermore, it is preferable that a raindrop prevention piece protrudes from the upper end on the outdoor side of the lower plate.

本発明によれば、継手の前面板を上下に２分割して継手凹溝をなくして分割空間を形成したことによって、軒樋と継手が接続された外観にあって軒樋の凹溝と継手の分割空間が一体となり、従来あった軒樋の凹溝と継手凹溝との凹没量の差による外観の違和感がなくなると共に、継手の分割空間から軒樋の凹溝を経て凹溝に配設された導水孔へと雨水が入り、継手の前面板を伝って雨水が下方に落下しにくい軒樋の継手装置を得ることができる。 According to the present invention, the front plate of the joint is vertically divided into two to eliminate the joint groove and form a divided space. As a result, there is no sense of incongruity in the appearance due to the difference in the amount of depression between the groove groove of the eaves and the joint groove, and the groove is arranged from the joint space to the groove through the groove of the eaves. It is possible to obtain an eaves-joint joint device in which rainwater enters the provided water guide hole and the rainwater does not easily fall down through the front plate of the joint.

以下に、本発明の軒樋の継手装置の実施の形態を示す図面を参照しつつ、詳細に説明する。 Below, it demonstrates in detail, referring drawings which show embodiment of the eaves-joint coupling apparatus of this invention.

本発明の軒樋の継手装置の継手２の材質は、屋外に使われるプラスチック建材として従来公知の樹脂を適宜選択でき、特に限定するわけではないが、例えば、硬質塩化ビニル樹脂、アクリル樹脂、ポリカーボネート樹脂、ＡＥＳ樹脂（アクリロニトリル・エチレン−プロピレンゴム・スチレン樹脂）等の熱可塑性樹脂やこれらの混合物を含むものを使用できる。また、軒樋１の材質は、継手２と同一であっても異なるものであってもよい。 The material of the joint 2 of the eaves joint device of the present invention can be appropriately selected from conventionally known resins as plastic building materials used outdoors, and is not particularly limited. For example, hard vinyl chloride resin, acrylic resin, polycarbonate Resin, AES resin (acrylonitrile, ethylene-propylene rubber, styrene resin) and other thermoplastic resins and those containing a mixture thereof can be used. Further, the material of the eaves 1 may be the same as or different from that of the joint 2.

軒樋１は、図１に示すように、底壁板１２と底壁板前端から立ち上がる前壁板１３と底壁板後端から立ち上がる後壁板１４とからなる。前壁板１３は、前壁上部板１３２と前壁下部板１３３とで形成されており、前壁下部板１３３は、底壁板前端から立ち上がって上方へいくにしたがって前方へいくように傾斜しており、前壁上部板１３２は、上方へいくにつれて後方に傾斜している。前面下部板上端には、横手方向に外面から内方へ凹溝５を設けてあり、さらに、その凹溝５に導水孔６が配設されてある。 As shown in FIG. 1, the eaves basket 1 includes a bottom wall plate 12, a front wall plate 13 rising from the front end of the bottom wall plate, and a rear wall plate 14 rising from the rear end of the bottom wall plate. The front wall plate 13 is formed by a front wall upper plate 132 and a front wall lower plate 133. The front wall lower plate 133 rises from the front end of the bottom wall plate and inclines so as to move forward. The front wall upper plate 132 is inclined backward as it goes upward. At the upper end of the front lower plate, a concave groove 5 is provided in the lateral direction from the outer surface to the inner side, and a water guide hole 6 is disposed in the concave groove 5.

継手２は、図２に示すように、軒樋１，１を直線状に接続するもので、屋外側に位置する前面板２１と、建屋側に位置する後面板２４と、この両者の下辺を接続する底面板２５とで構成され、内側には軒樋１形状に沿って爪嵌合片４が設けられている。前面板２１の上部板２２と下部板２３は軒樋１の凹溝５に相当する位置で上下に２分割され分割空間３を形成し、２分割された上部板２２と下部板２３とを上下に間隔を隔てて爪嵌合片４で連結されている。 As shown in FIG. 2, the joint 2 connects the eaves ridges 1 and 1 in a straight line. The front plate 21 located on the outdoor side, the rear plate 24 located on the building side, and the lower sides of the two are connected. A claw fitting piece 4 is provided along the shape of the eaves bowl 1 on the inner side. The upper plate 22 and the lower plate 23 of the front plate 21 are vertically divided into two at the position corresponding to the concave groove 5 of the eaves 1 to form a divided space 3, and the upper and lower divided plates 22 and 23 are moved up and down. The nail fitting pieces 4 are connected to each other with a gap therebetween.

また、爪嵌合片４は、図３〜図５に示すように、継手２内に挿入した軒樋１，１の長手方向の端部を爪嵌合片４で当接させ、例えば接着剤を塗布して、軒樋１と継手２を固定するため、軒樋１の板厚が挿入できるように、継手２内側の幅方向中央部に略コ字状の断面を有し、継手２の内周面全長に亘って形成されている。 As shown in FIGS. 3 to 5, the claw fitting piece 4 abuts the longitudinal ends of the eaves rods 1 and 1 inserted into the joint 2 with the claw fitting piece 4, for example, an adhesive. In order to fix the eaves rod 1 and the joint 2, the joint 2 has a substantially U-shaped cross section at the center in the width direction so that the plate thickness of the eaves rod 1 can be inserted. It is formed over the entire inner peripheral surface.

次に、継手２の前面板２１を伝って雨水が下方に落下する排水経路について説明する。先ず、前面板２１の上部板２２に降った雨水は、上部板２２の壁面を伝いながら分割空間３へ落ち、軒樋１、１の凹溝５に集まり、さらに凹溝５に定間隔で配設されている導水孔６から軒樋１内へ流れ込む。 Next, a drainage path through which rainwater falls downward along the front plate 21 of the joint 2 will be described. First, rainwater that has fallen on the upper plate 22 of the front plate 21 falls into the divided space 3 along the wall surface of the upper plate 22, gathers in the concave grooves 5 of the eaves 1, 1, and is further arranged in the concave grooves 5 at regular intervals. It flows into the eaves 1 from the water guide hole 6 provided.

また、雨だれ防止片８を設けることにより、継手２の上部板２２に降った雨水で風などの影響で分割空間３へ集まらない雨水を、雨だれ防止片８を案内片として分割空間３へ流入させるものであり、その形状は特に限定されるものではないが、少なくとも、継手２の長手方向に沿って連続的に、下部板２３の屋外側上端に水平又は水平より上方に突設してあるのが望ましい。 Further, by providing the raindrop prevention piece 8, rainwater that has fallen on the upper plate 22 of the joint 2 and does not collect in the divided space 3 due to the influence of wind or the like flows into the divided space 3 using the raindrop prevention piece 8 as a guide piece. The shape is not particularly limited, but at least continuously along the longitudinal direction of the joint 2, the upper end on the outdoor side of the lower plate 23 protrudes horizontally or above the horizontal. Is desirable.

このようにして本発明の軒樋の継手装置は、軒樋と継手が接続された外観にあって、継手の分割空間を軒樋の凹溝に重ねて位置させたことにより、軒樋の凹溝と継手の分割空間が一体となり、従来あった軒樋の凹溝と継手凹溝との凹没量の差による外観の違和感がなくなると共に、分割空間から軒樋の凹溝を経て凹溝に配設された導水孔へと雨水が入り、継手の前面板を伝って雨水が下方に落下しにくい。 In this way, the eaves-joint joint device of the present invention has an appearance in which the eaves eave and the joint are connected, and the joint split space is positioned so as to overlap the eaves eaves groove. The split space between the groove and the joint is integrated, and there is no discomfort in the appearance due to the difference in the amount of recess between the groove groove of the eaves and the joint groove, and from the split space to the groove through the groove of the eaves Rainwater enters the installed water guide holes, and the rainwater is unlikely to fall down along the front plate of the joint.

以下に、実施例に基づいて図１〜図７を参照にしながら詳細に説明するが、本発明は実施例により限定されるものではない。 Below, based on an Example, it demonstrates in detail, referring FIGS. 1-7, but this invention is not limited by an Example.
