Description

【0001】
【発明の属する技術分野】
本発明は、軒樋に係り、特に建屋に施工されても経時的変化が少ない軒樋に関する。
【0002】
【従来の技術】
従来、軒樋は、建屋に600mm間隔で取り付けられた複数の吊り具に吊されて取り付けられている。これは、あまりに長い間隔で軒樋を固定すると、軒樋同士を接続している継手部分(長手方向における両端部)が下に落ち込んだり、太陽光の影響で伸びようとする軒樋が蛇行したりするためである。
【0003】
【発明が解決しようとする課題】
しかしながら、最近、軒樋の取付作業効率を考え、この間隔を広げて固定することが要求されたきた。ここで、単純に吊り具の間隔を開けると、前述の如くその継手部分が下に落ち込んだり、軒樋が蛇行したりするという課題がある。
【0004】
したがって、本発明の目的は、軒樋を固定する吊り具の取付間隔を広げても上記課題が生じない軒樋を提供することにある。
【0005】
【課題を解決するための手段】
本発明者は、上記に鑑み鋭意検討を行った結果、軒樋の底板をその長手方向の両端へいくに従ってその内側へ1.8mあたり3〜5mm傾斜させ、これにより上記課題を解決できることを見いだし、本発明を完成させた。
【0006】
【発明の実施の形態】
本発明の軒樋において、軒樋の底板をその長手方向の両端へいくに従ってその内側へ1.8mあたり3〜5mm傾斜させたのは、軒樋継手が下に落ち込むのを予め計算して設計したためである。この傾斜割合は、軒樋の素材、継手の重さに応じて適宜選択できる。
【0007】
また、上記屋外側壁板の内壁にその内側へ突出した中空リブを設けることにより、軒樋の継手部分の落ち込みや軒樋の蛇行を防止することができる。これは、屋外側壁板が屋内側壁板より太陽光を受けやすく曲がりやすいため、屋外側壁板だけに設けることが好ましい。また、該中空リブは、この中空リブ自体が太陽光からの影響を受け難くするため、屋外側壁板の内壁に設けられることが好ましい。また、屋内側壁板との兼ね合いから、この中空リブの高さ位置は、前記屋内側壁板の耳縁の高さ位置と同程度から屋外側壁の耳縁の高さ位置との間にあるのが好ましい。
【0008】
上記屋外側壁板は、その下端から上記中空リブまで鉛直に形成され、屋外側壁板の該中空リブ配置位置より上方を軒樋の内側へなだらかに傾斜されることにより、蛇行が少なくなる。蛇行が少なくなる理由は、鋭意研究の結果、蛇行原因の太陽光を受けやすい形である屋外側壁板の内側傾斜部が、製品設計として要求される形状であるという条件の下、内側への傾斜部分を最小限にして太陽光の受光面積を最小限にしたためである。
【0009】
上記床板に長手方向に伸びる突出部を設けることにより、床板の補強ができ、これにより、軒樋の継手部分(長手方向における両端部)が下に落ち込むことがなく、軒樋が蛇行し難くなる。該突出部は、幾つ形成しても良く、好ましくは、1つ又は2つ良い。
【0010】
本発明にかかる軒樋の素材にあっては、従来公知の合成樹脂を採用でき、具体的には、ポリ塩化ビニル樹脂、ポリエチレン樹脂、ポリスチレン樹脂、ポリプロピレン樹脂、ポリカーボネート樹脂、アクリロニトリル−ブタジエン−スチレン共重合体等がある。
【0011】
軒樋の屋外側壁板の外側と、屋内側壁板の内側に耐候性樹脂を被覆することにより、太陽光によって生じる伸縮を抑えることができる。これにより、軒樋の蛇行を抑えることができる。耐候性樹脂の被覆場所を屋外側壁板の外側と屋内側壁板の内側に限定したのは、かかる範囲に太陽光が多く当たることから屋外側と屋内側の熱変形バランスを均一に保たせ軒樋全体の熱変形バランスを均一に図るためである。該耐候性樹脂としては、アクリル樹脂、アクリルニトリルスチレン樹脂、AAS樹脂(アクリルニトリル・アクリルゴム・スチレン樹脂)、AES樹脂(アクリロニトリル・(エチレン・プロピレン・ジエン共重合体)・スチレン樹脂)、メタクリル樹脂及びフッ素樹脂等がある。
【0012】
本発明の軒樋は、全体で縦断面コ字状に形成された合成樹脂製の軒樋の底板をその長手方向の両端へいくに従って軒樋の内側へ1.8mあたり3〜5mm傾斜させ、上記屋外側壁板の内壁にその内側へ突出した中空リブを設け、この中空リブの高さ位置を前記屋内側壁板の耳縁の高さ位置と同程度から屋外側壁の耳縁の高さ位置との間とし、上記屋外側壁板を、その下端から上記中空リブまで鉛直に形成され、屋外側壁板の該中空リブ配置位置より上方を軒樋の内側へなだらかに傾斜させ、さらに上記床板にその長手方向に伸びる突出部を設け、これにより、吊り具同士の間隔を開けても、軒樋同士を接続している継手部分(長手方向における両端部)が下に落ち込んだり、太陽光を受けても軒樋が蛇行しない。
【0013】
【実施例】
本発明にかかる一実施例について、図1及び図2を参照しつつ説明する。図1は本発明を軒樋に具現化した実施例を模式的に示した斜視図であり、図2はこの実施例を施工した際の測定方法を示す参考図である。
【0014】
本実施例の軒樋は、図1のような全体で縦断面コ字状に形成されたポリ塩化ビニル樹脂製の軒樋であり、屋外側壁板1と、屋内側壁板2と、これらの底辺同士をつなぐ底板3を備え、前記屋外側壁板1と前記屋内側壁板2の上端に中空の耳縁4、5が設けられたものである。また、上記屋外側壁板1の内壁にその内側へ突出した中空リブ6が設けられ、この中空リブ6の高さ位置が前記屋内側壁板2の耳縁5の高さ位置と同程度の高さ位置にある。上記屋外側壁板1は、その下端から上記中空リブ6まで鉛直に形成され、屋外側壁板1の該中空リブ6配置位置より上方を軒樋の内側へなだらかに傾斜している。また、上記床板3には、その長手方向に伸びる突出部7がある。
【0015】
図示は省略したが、この軒樋は、該底板3をその長手方向の両端へいくに従って軒樋の内側へ1.8mあたり5mm傾斜させたものであり、屋外側壁板1の外側と、屋内側壁板2の内側に耐候性樹脂たるAES樹脂(アクリロニトリル・(エチレン・プロピレン・ジエン共重合体)・スチレン樹脂)を被覆したものである。
【0016】
本実施例にあっては、本実施例にかかる軒樋を1200mm間隔で取り付けた吊り具に施工し、軒樋継手の高さ位置を確認したところ、施工直後は軒樋の施工基準高さ位置から2mm高かったが、施工1ヶ月後には施工基準高さ位置と同じ高さ位置(±0mm)になった(図2参照)。本実施例の軒樋は、2ヶ月後でも1ヶ月後と同じ高さ位置にあったので、軒樋継手部分の落ち込みを維持できた。従来品では、施工1ヶ月後に施工基準高さ位置より8mm低くなった。また、本実施例にあっては、上記構成により、太陽光の影響による軒樋の蛇行も少なくなった。
【0017】
【発明の効果】
本発明にあっては、屋外側壁板と、屋内側壁板と、これらの底辺同士をつなぐ底板を備え、前記屋外側壁板と前記屋内側壁板の上端又はその近傍に中空の耳縁が設けられ、全体で縦断面コ字状に形成された合成樹脂製の軒樋において、該底板をその長手方向の両端へいくに従って軒樋の内側へ1.8mあたり3〜5mm傾斜させ、これにより、1200mm間隔で取り付けられた複数の吊り具に吊されても軒樋同士を接続している継手部分(長手方向における両端部)が下に落ち込んだり、太陽光の影響で伸びようとする軒樋が蛇行したりしなくなった。
【0018】
他の発明にあっては、上記屋外側壁板の内壁にその内側へ突出した中空リブを設け、この中空リブの高さ位置を前記屋内側壁板の耳縁の高さ位置と同程度から屋外側壁の耳縁の高さ位置との間にし、これにより、屋外側壁板の補強効果が図れ軒樋の継手部分の落ち込みや軒樋の蛇行を防止することができた。
【0019】
他の発明にあっては、上記屋外側壁板を、その下端から上記中空リブまで鉛直に形成し、屋外側壁板の該中空リブ配置位置より上方を軒樋の内側へなだらかに傾斜させ、これにより、太陽光の受光面積を最小限にし、軒樋の蛇行を防止することができた。
【0020】
他の発明にあっては、上記床板にその長手方向に伸びる突出部を設け、これにより吊り具同士の間隔を開けても、軒樋同士を接続している継手部分(長手方向における両端部)が下に落ち込まなくなった。
【0021】
他の発明にあっては、上記屋外側壁板の外側と、上記屋内側壁板の内側に耐候性樹脂を被覆し、屋外側と屋内側の熱変形バランスを軒樋全体からみて均一に保たせ、これにより、軒樋の蛇行を抑えることができる。

BACKGROUND OF THE INVENTION
The present invention relates to eaves eaves, and more particularly to eaves elevates with little change over time even when constructed in a building.
[0002]
[Prior art]
Conventionally, the eaves are hung and attached to a plurality of hanging tools attached to the building at intervals of 600 mm. This is because if the eaves are fixed at an excessively long interval, the joints connecting the eaves (both ends in the longitudinal direction) will drop down, or the eaves will expand due to the influence of sunlight. This is because
[0003]
[Problems to be solved by the invention]
Recently, however, it has been required to widen and fix the gap in consideration of the eaves mounting work efficiency. Here, there is a problem that when the interval of the lifting tool is simply opened, the joint portion falls down as described above, or the eaves rod meanders.
[0004]
Therefore, an object of the present invention is to provide an eave ridge that does not cause the above-described problem even when the attachment interval of the suspension for fixing the eave ridge is increased.
[0005]
[Means for Solving the Problems]
As a result of intensive studies in view of the above, the present inventor found that the bottom plate of the eaves wall is inclined 3 to 5 mm per 1.8 m inward as it goes to both ends in the longitudinal direction, thereby finding that the above problems can be solved. The present invention has been completed.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
In the eaves eaves of the present invention, the bottom plate of the eaves eaves is inclined 3 to 5 mm per 1.8 m as it goes to both ends in the longitudinal direction. This is because. This inclination ratio can be appropriately selected according to the material of the eaves and the weight of the joint.
[0007]
Further, by providing a hollow rib projecting inward on the inner wall of the outdoor side wall plate, it is possible to prevent the joint portion of the eaves bowl from dropping or the eaves meandering. This is preferably provided only on the outdoor side wall plate because the outdoor side wall plate is more susceptible to sunlight than the indoor side wall plate and is easily bent. The hollow rib is preferably provided on the inner wall of the outdoor side wall plate so that the hollow rib itself is not easily affected by sunlight. In addition, from the balance with the indoor side wall plate, the height position of the hollow rib is between the height position of the ear edge of the indoor side wall plate and the height position of the ear edge of the outdoor side wall plate. preferable.
[0008]
The outdoor side wall plate is vertically formed from the lower end thereof to the hollow rib, and the meandering is reduced by being gently inclined to the inside of the eaves above the position of the outdoor rib of the outdoor side wall plate. The reason for the decrease in meandering is that, as a result of intensive research, the inwardly inclined part of the outdoor side wall plate that is susceptible to sunlight caused by meandering is inwardly inclined under the condition that it is the shape required for product design. This is because the light receiving area of sunlight is minimized by minimizing the portion.
[0009]
By providing protrusions extending in the longitudinal direction on the floor board, it is possible to reinforce the floor board, so that the joint portions (both ends in the longitudinal direction) of the eaves do not fall down and the eaves are less likely to meander. . Any number of the protrusions may be formed, and preferably one or two.
[0010]
In the eaves material according to the present invention, a conventionally known synthetic resin can be used, and specifically, polyvinyl chloride resin, polyethylene resin, polystyrene resin, polypropylene resin, polycarbonate resin, acrylonitrile-butadiene-styrene copolymer. There are polymers and the like.
[0011]
By covering the outside of the outdoor side wall plate of the eaves with the weather resistant resin on the inside of the indoor side wall plate, expansion and contraction caused by sunlight can be suppressed. Thereby, the meandering of the eaves can be suppressed. The reason for limiting the weather-resistant resin coating location to the outside of the outdoor side wall plate and the inside of the indoor side wall plate is to keep the heat deformation balance between the outdoor side and the indoor side uniform, because a lot of sunlight hits this range. This is for the purpose of achieving a uniform thermal deformation balance. As the weather resistant resin, acrylic resin, acrylonitrile styrene resin, AAS resin (acrylonitrile / acrylic rubber / styrene resin), AES resin (acrylonitrile / (ethylene / propylene / diene copolymer) / styrene resin), methacrylic resin And fluororesin.
[0012]
The eaves of the present invention is inclined by 3 to 5 mm per 1.8 m toward the inside of the eaves as it goes to both ends in the longitudinal direction of the bottom plate of the synthetic resin eaves formed in a U-shaped longitudinal section as a whole. A hollow rib projecting inward is provided on the inner wall of the outdoor side wall plate, and the height position of the hollow rib is approximately the same as the height position of the ear edge of the indoor side wall plate to the height position of the ear edge of the outdoor side wall plate. The outdoor side wall plate is vertically formed from the lower end thereof to the hollow rib, and the upper side of the outdoor side wall plate is gently inclined toward the inside of the eaves, and the floor plate is further elongated in the longitudinal direction. Protrusions that extend in the direction are provided, so that even if there is a gap between the hanger, even if the joint parts (both ends in the longitudinal direction) connecting the eaves fall down or receive sunlight The eaves do not meander.
[0013]
【Example】
An embodiment according to the present invention will be described with reference to FIGS. FIG. 1 is a perspective view schematically showing an embodiment in which the present invention is embodied in an eaves, and FIG. 2 is a reference diagram showing a measurement method when this embodiment is constructed.
[0014]
The eaves eaves of this embodiment are eaves eaves made of polyvinyl chloride resin formed as a whole in a U-shaped longitudinal section as shown in FIG. 1, and include an outdoor side wall plate 1, an indoor side wall plate 2, and the bottom sides thereof. A bottom plate 3 is provided to connect each other, and hollow ear edges 4 and 5 are provided at upper ends of the outdoor side wall plate 1 and the indoor side wall plate 2. Further, a hollow rib 6 projecting inward is provided on the inner wall of the outdoor side wall plate 1, and the height position of the hollow rib 6 is substantially the same as the height position of the ear edge 5 of the indoor side wall plate 2. In position. The outdoor side wall plate 1 is vertically formed from the lower end thereof to the hollow rib 6, and the upper side of the outdoor side wall plate 1 above the position where the hollow rib 6 is disposed is gently inclined toward the inside of the eaves. The floor plate 3 has a protruding portion 7 extending in the longitudinal direction.
[0015]
Although not shown, this eaves wall is obtained by inclining the bottom plate 3 to the inside of the eaves wall by 5 mm per 1.8 m as it goes to both ends in the longitudinal direction. The inside of the plate 2 is coated with AES resin (acrylonitrile / (ethylene / propylene / diene copolymer) / styrene resin) which is a weather resistant resin.
[0016]
In this example, the eaves rod according to the present example was installed on a lifting tool attached at intervals of 1200 mm, and the height position of the eaves joint was confirmed. However, it became the same height position (± 0 mm) as the construction reference height position after 1 month of construction (see FIG. 2). Since the eaves of this example was in the same height position as after 1 month even after 2 months, it was possible to maintain the depression of the eaves joint portion. In the conventional product, it was 8 mm lower than the construction reference height after one month of construction. Moreover, in the present Example, the meandering of the eaves by the influence of sunlight decreased with the said structure.
[0017]
【The invention's effect】
In the present invention, an outdoor side wall plate, an indoor side wall plate, and a bottom plate that connects these bases are provided, and a hollow ear edge is provided at or near the upper end of the outdoor side wall plate and the indoor side wall plate, In the eaves made of synthetic resin having a generally U-shaped vertical cross section, the bottom plate is inclined 3-5 mm per 1.8 m toward the inside of the eaves as it goes to both ends in the longitudinal direction. Even if hung by multiple hanging fixtures attached to the eaves, the joints that connect the eaves to each other (both ends in the longitudinal direction) fall down or the eaves that are going to stretch under the influence of sunlight meander No longer.
[0018]
In another aspect of the invention, a hollow rib projecting inward is provided on the inner wall of the outdoor side wall plate, and the height position of the hollow rib is set to be the same as the height position of the ear edge of the indoor side wall plate. By this, the effect of reinforcing the outdoor side wall plate can be achieved, and the drop of the joint portion of the eaves and the meandering of the eaves can be prevented.
[0019]
In another invention, the outdoor side wall plate is vertically formed from the lower end thereof to the hollow rib, and the upper side of the outdoor side wall plate is inclined gently toward the inside of the eaves, thereby It was possible to minimize the light receiving area of sunlight and to prevent meandering of the eaves.
[0020]
In another invention, the above-mentioned floor board is provided with a projecting portion extending in the longitudinal direction thereof, thereby connecting the eaves to each other even if the spacing between the suspensions is opened (both ends in the longitudinal direction) No longer fell down.
[0021]
In another invention, the outside of the outdoor side wall plate and the inside of the indoor side wall plate are coated with a weather resistant resin, and the thermal deformation balance between the outdoor side and the indoor side is kept uniform from the whole eaves, Thereby, the meandering of the eaves can be suppressed.
