【発明の属する技術分野】
本発明は、水切り胴縁構造、水切り胴縁およびその製造方法に関する。例えば、木造建物等の外壁材の下地となる水切り胴縁構造、水切り胴縁およびその製造方法に関する。
【0002】
【背景技術】
従来、パネル工法で建てられた木造建物の外壁は、図9に示すように、図示しない建物の基礎の上に胴縁下地用パネル13を設けて、その外側に全面に亘って防水シート14を貼り、この防水シート14の表面に複数の断面矩形の胴縁90を略水平に取り付けて、その上からサイディングボード等の外壁仕上用の化粧パネル15を固定することによって構成されていた(例えば、特開平7-158181号公報等参照)。
【0003】
【発明が解決しようとする課題】
しかし、上記構成では、万一化粧パネル15の内側に雨水が浸入すると、胴縁90は断面矩形であるから、浸入した雨水は胴縁90の上面に溜まってしまうおそれがあった。
【0004】
本発明の目的は、排水性がよい水切り胴縁構造、水切り胴縁およびその製造方法を提供することにある。
【0005】
【課題を解決するための手段】
上記目的を達成するため、本発明である水切り胴縁構造、水切り胴縁およびその製造方法は、次の構成を採用する。
本発明を図面を参照して説明すると、請求項1に記載の水切り胴縁構造は、胴縁下地13に支持される支持面10Aと、上側となる上面10Bと、壁面材15を取り付ける取付面10Cとを有する水切り胴縁10を備えた水切り胴縁構造において、前記上面には、前記取付面および前記支持面のうちいずれか一方の面10A側から他方の面10C側に向かって下方に傾斜する勾配が形成されるとともに、前記他方の面とそれに対向する前記胴縁下地または前記壁面材との間には、前記上面の前記他方の面側に集まった雨水を下方へ排水する排水路が設けられていることを特徴とする。
【0006】
この発明によれば、壁面材を通り抜けて浸入した雨水が壁面材裏面を伝って水切り胴縁の上面へ流れ落ちてきても、その雨水は上面の勾配によって取付面および支持面のうちいずれか一方の面側から他方の面側へ流れ、更に他方の面側に設けられた排水路を通って下方に排水されるから、排水性をよくすることができる。したがって、水切り胴縁、胴縁下地および壁面材の湿潤状態を避けることができるから、耐久性が向上する。
特に、上面に取付面側から支持面側に向かって下方に傾斜する勾配を設けた場合は、壁面材裏面の湿潤状態を避けることができ、また、上面に支持面側から取付面側に向かって下方に傾斜する勾配を設けた場合、胴縁下地表面の湿潤状態を避けることができる。
ここにおいて、排水路は、水切り胴縁の他方の面に溝を形成してもよいが、他方の面とそれに対向する胴縁下地または壁面材との間にスペーサを一定間隔置きに介在させて構成してもよい。
【0007】
請求項2に記載の水切り胴縁は、胴縁下地に支持される支持面と、上側となる上面と、壁面材を取り付ける取付面とを有する水切り胴縁において、前記上面には、前記取付面および前記支持面のうちいずれか一方の面側から他方の面側に向かって下方に傾斜する勾配が形成されていることを特徴とする。
この発明によれば、請求項1と同様に、排水性をよくすることができる。
【0008】
請求項3に記載の水切り胴縁は、請求項2に記載の水切り胴縁において、前記他方の面には、その長手方向と略直交方向の溝11が形成されていることを特徴とする。
この発明によれば、上面へ流れ落ちてきた雨水が、他方の面に設けられた溝を通って下方に排水されるから、請求項1と同様に、排水性をよくすることができる。また、この構成であれば、部品点数を少なくすることができる。
【0009】
請求項4に記載の水切り胴縁の製造方法は、水切り胴縁の厚みに等しい板材30を準備し、前記板材の表面に断面略三角形状の切り込みを板材の一側縁に平行に入れて、前記板材を断面略台形の帯状材32に分割することを特徴とする。
この発明によれば、平板材の表面に対して略垂直方向から例えば丸鋸の断面略三角形状の刃を当てるだけで水切り胴縁を製造できる。したがって、表面に対して傾斜した角度に丸鋸の刃を当てる場合に比べて、丸鋸の刃を傷めることなく正確に加工できるので、水切り胴縁を容易に製造することができる。
【0010】
請求項5に記載の水切り胴縁の製造方法は、水切り胴縁の厚みに等しい板材30を準備し、前記板材の表面に切り込みを交互に逆向きとなるようにかつ板材の一側縁に平行に入れて、断面略台形の帯状材32に分割することを特徴とする。
この発明によれば、平板材の表面に対して傾斜した角度で例えば丸鋸の平板状の刃を当てるだけで水切り胴縁を製造できる。したがって、請求項4に記載した水切り胴縁の製造方法に比べて、材料の無駄が少ないから、水切り胴縁を安価に製造することができる。
【0011】
請求項6に記載の水切り胴縁の製造方法は、請求項4または5に記載の水切り胴縁の製造方法において、前記両側切断部が表面に対して傾斜した帯状材の長手方向に直交する幅方向中央に切り込みを切断部と平行に入れて、帯状材を二分割することを特徴とする。
この発明によれば、請求項4または5に記載された帯状材の表面に対して略垂直方向から例えば丸鋸の平板状の刃を当てるだけで二本の水切り胴縁を製造できる。したがって、水切り胴縁を容易かつ安価に製造することができる。
【0012】
請求項7に記載の水切り胴縁の製造方法は、水切り胴縁の厚みに等しい板材30を準備し、前記板材の表面に切り込みを傾斜した角度でかつ板材の一側縁に平行に入れて、断面略平行四辺形の帯状材32に分割することを特徴とする。
この発明によれば、平板材の表面に対して例えば丸鋸の平板状の刃を傾斜した一定角度に維持した状態で、板材を一定方向に送り出すだけで製造できるから、請求項5に比べ容易に製造することができる。
【0013】
請求項8に記載の水切り胴縁の製造方法は、請求項4から7のいずれかに記載の水切り胴縁の製造方法において、前記板材の表面には、予め前記帯状材に切り出す方向と略直交方向の溝11を形成しておくことを特徴とする。
この発明によれば、予め平板材に切り出す方向と略直交方向の溝を形成しておくので、帯状材に分割された後に溝を形成する場合に比べ一度に加工できるから、水切り胴縁を容易かつ安価に製造することができる。
【0014】
【発明の実施の形態】
以下、本発明の各実施形態を図面に基づいて説明する。なお、以下の実施形態の説明にあたって、同一構成要件については同一符号を付し、その説明を省略もしくは簡略化する。
〔第1実施形態〕
図1には、本発明の第1実施形態における壁構造1が示されている。
壁構造1は、木造建物の外壁であって、鉛直に設置された胴縁下地としての胴縁下地用パネル13と、この胴縁下地用パネル13の外側に全面に亘って設置された防水シート14と、この防水シート14の外側に水平かつ高さ方向に所定間隔で設置された複数本の水切り胴縁10と、これら水切り胴縁10の表面に取り付けられ、かつ胴縁下地用パネル13の全面に亘って設置された壁面材としての化粧パネル15とを含んで構成されている。
【0015】
水切り胴縁10は、図2に示すように、断面台形であって長手方向に所定長さを有し、防水シート14に覆われた胴縁下地用パネル13に固定される支持面10Aと、化粧パネル15を取り付ける取付面10Cと、取付面10Cおよび支持面10Aのうちいずれか一方の面側から他方の面側に向かって下方に傾斜する勾配として、前記支持面10A側から前記取付面10C側に向かって下方に傾斜する勾配を有する上面10Bとを有している。
なお、上面10Bの勾配は、雨水が自然に流れるのに十分な勾配であればよく、適宜決められてよい。
また、取付面10C上には、一定間隔置きにその長手方向と直交する方向に断面四角形状に溝11が設けられ、この溝11は雨水が通り抜けるのに十分な幅と深さを有するが、この幅と深さは適宜決められてよい。
【0016】
したがって、暴風雨等により雨水が化粧パネル15の裏側まで浸入した場合、この雨水は化粧パネル15の裏面を伝って流れ落ち、水切り胴縁10の上面10Bに到達して、取付面10Cに設けられた溝11を通り抜けて自然排水される。また、防水シート14に雨水が付着した場合も、雨水は防水シート14を伝って水切り胴縁10の上面10Bに達し、上面10B上を支持面10A側から取付面10C側へと伝って取付面10C側に流れ込み、溝11から排水される。
【0017】
図3および図4には、本実施形態における水切り胴縁10の製造方法が示されている。
図3および図4に示すように、水切り胴縁10に等しい厚みを有する板材としての平板材30を準備し、図示しない丸鋸を備えた製材機にセットする。なお、製材機は三種類の丸鋸31A、31B、31Cを交換して取り付けできるようになっている。丸鋸31Aは溝11を形成するための断面四角形状の刃を有し、丸鋸31Bは平板材30を断面三角形状に切り欠くための断面三角形状の刃を有し、丸鋸31Cは平板材30を二分割するための平板状の刃を有する。
先ず、平板材30の表面に、その表面に対して垂直方向から丸鋸31Aの刃を当て、平板材30の長手方向(水切り胴縁10の長手方向)に直交する方向に溝11を形成し、これを平板材30の長手方向に一定間隔置きに繰り返す。
次に、この平板材30の表面に垂直方向から丸鋸31Bの刃を当て、平板材30の長手方向(水切り胴縁10の長手方向)に平行に断面三角形状の切り込みを入れ、これを平板材30の長手方向に直交する幅方向に一定間隔置きに繰り返して断面略台形の帯状材32とする。
最後に、各帯状材32にその垂直方向に、かつ、帯状材32の長手方向に直交する幅方向中央に、丸鋸31Cの刃を当て、帯状材32の長手方向(水切り胴縁10の長手方向)に平行に切り込みを入れて、帯状材32を二分割して水切り胴縁10とする。
【0018】
したがって、本記実施形態における水切り胴縁10によれば、以下の効果がある。
(1)化粧パネル15を通り抜けて浸入した雨水が化粧パネル15の裏面を伝って水切り胴縁10の上面10Bへ流れ落ちてきても、取付面10C側に形成された溝11を通って下方に排水されるから、排水性をよくすることができる。したがって、水切り胴縁10および化粧パネル15の裏面の湿潤状態を避けることができるから、耐久性が向上する。
【0019】
また、本記実施形態における水切り胴縁10の製造方法によれば、以下の効果がある。
(2)平板材30の表面に対して垂直方向から丸鋸31A、31B、31Cの刃を当てるだけで水切り胴縁10を製造できる。したがって、表面に対して傾斜した角度に丸鋸の刃を当てる場合に比べて、丸鋸31A、31B、31Cの刃を傷めることなく正確に加工できるので、水切り胴縁10を容易に製造することができる。
(3)予め平板材30に溝11を形成しておくので、帯状材32に分割された後に溝11を形成する場合に比べ一度に加工できるから、水切り胴縁10を容易かつ安価に製造することができる。
【0020】
〔第2実施形態〕
本発明の第2実施形態における水切り胴縁50が第1実施形態と異なる点は、図5に示すように、断面平行四辺形である点である。
この水切り胴縁50の製造方法は、図6に示すように、予め溝11を形成した平板材30の表面に、この表面に対して傾斜した一定の角度で丸鋸31Cの刃を当てて、平板材30の長手方向に平行に切り込みを入れ、平板材30を断面略平行四辺形の帯状材32に分割する。つまり、丸鋸31Cはその傾斜角度を固定したままで平板材30の長手方向に往復運動させながら、平板材30の長手方向に直交する方向に平板材30を一定間隔で送り出して帯状材32を製造する。そして、この帯状材32を水切り胴縁50とする。
したがって、本実施形態によれば、第1実施形態で述べた(1)、(3)の効果に加えて以下の効果がある。
【0021】
(4)平板材30の表面に対して丸鋸31Cの刃を傾斜した一定の角度に維持した状態で、平板材30を一定方向に送り出すだけで製造できるから、第1実施形態に比べ容易に製造することができる。
【0022】
なお、本発明は、前述の実施形態に限定されるものではなく、本発明の目的を達成できる範囲での変形、改良等は本発明に含まれるものである。
例えば、第1実施形態では、平板材30の表面に垂直方向から丸鋸31Bの刃を当て、平板材30の長手方向に平行に断面三角形状の切り込みを入れて断面略台形の帯状材32を形成したが、図7および図8に示す水切り胴縁70のように、平板材30の表面に対して交互に逆向きとなるように丸鋸31Cの刃を当て、平板材30の長手方向に平行に切り込みを入れて断面略台形の帯状材32を形成してもよい。
そして、第1実施形態と同様に、各帯状材32の長手方向に直交する幅方向中央に、帯状材32の長手方向(水切り胴縁70の長手方向)に平行に切り込みを入れて、帯状材32を2分割して水切り胴縁70としてもよい。
このようにしても、平板材30に無駄になる部分が少ないから、水切り胴縁70を安価に製造することができる。
なお、帯状材32を水切り胴縁70に分割する前に溝11を帯状材32に設けても構わない。このようにすれば、水切り胴縁70に分割後に溝11を形成する場合に比べ一度に加工できるから、水切り胴縁70を容易かつ安価に製造することができる。
【0023】
また、各実施形態では、水切り胴縁10,50に溝11を設けて排水路としたが、溝11を設けずに取付面10Cと化粧パネル15との間にワッシャー等を介在させて隙間を形成し、この隙間を排水路として利用してもよい。このようにすれば、上面10Bの勾配によって取付面10C側へ流れた雨水が排水路を通って下方に排水されるから、排水性をよくすることができる。また、水切り胴縁の形状が単純化されるから、水切り胴縁を更に容易かつ安価に製造することができる。
【0024】
また、各実施形態では、上面10Bに支持面10A側から取付面10C側に向かって下方に傾斜する勾配を形成したが、取付面10C側から支持面10A側に向かって下方に傾斜する勾配を形成してもよい。このようにしても、第1実施形態で述べた(2)(3)の効果および第2実施形態で述べた(4)の効果に加え、以下の効果を奏することができる。
(5)化粧パネル15を通り抜けて浸入した雨水が化粧パネル15の裏面を伝って水切り胴縁10の上面10Bへ流れ落ちてきても、その雨水は取付面10C側から支持面10A側へ流れ、支持面10Aに形成された溝11を通って下方に排水されるから、排水性をよくすることができる。したがって、水切り胴縁10および化粧パネル15の裏面の湿潤状態を避けることができるから、耐久性が向上する。
また、製造工程において平板材30を切り出す角度を変えるだけでよいから、容易に製造でき、安価である。
【0025】
【発明の効果】
本発明である水切り胴縁構造、水切り胴縁およびその製造方法によれば、以下の効果を奏することができる。
請求項1に記載の発明によれば、壁面材を通り抜けて浸入した雨水が壁面材裏面を伝って水切り胴縁の上面へ流れ落ちてきても、その雨水は上面の勾配によって取付面および支持面のうちいずれか一方の面側から他方の面側へ流れ、更に他方の面側に設けられた排水路を通って下方に排水されるから、排水性をよくすることができる。したがって、水切り胴縁、胴縁下地および壁面材の湿潤状態を避けることができるから、耐久性が向上する。
特に、上面に取付面側から支持面側に向かって下方に傾斜する勾配を設けた場合は、壁面材裏面の湿潤状態を避けることができ、また、上面に支持面側から取付面側に向かって下方に傾斜する勾配を設けた場合、胴縁下地表面の湿潤状態を避けることができる。
ここにおいて、排水路は、水切り胴縁の他方の面に溝を形成してもよいが、他方の面とそれに対向する胴縁下地または壁面材との間にスペーサを一定間隔置きに介在させて構成してもよい。
【0026】
請求項2に記載の発明によれば、請求項1と同様に、排水性をよくすることができる。
【0027】
請求項3に記載の発明によれば、上面へ流れ落ちてきた雨水が、他方の面に設けられた溝を通って下方に排水されるから、請求項1と同様に、排水性をよくすることができる。また、この構成であれば、部品点数を少なくすることができる。
【0028】
請求項4に記載の発明によれば、平板材の表面に対して略垂直方向から例えば丸鋸の断面略三角形状の刃を当てるだけで水切り胴縁を製造できる。したがって、表面に対して傾斜した角度に丸鋸の刃を当てる場合に比べて、丸鋸の刃を傷めることなく正確に加工できるので、水切り胴縁を容易に製造することができる。
【0029】
請求項5に記載の発明によれば、平板材の表面に対して傾斜した角度で例えば丸鋸の平板状の刃を当てるだけで水切り胴縁を製造できる。したがって、請求項4に記載した水切り胴縁の製造方法に比べて、材料の無駄が少ないから、水切り胴縁を安価に製造することができる。
【0030】
請求項6に記載の発明によれば、請求項4または5に記載された帯状材の表面に対して略垂直方向から例えば丸鋸の平板状の刃を当てるだけで二本の水切り胴縁を製造できる。したがって、水切り胴縁を容易かつ安価に製造することができる。
【0031】
請求項7に記載の発明によれば、平板材の表面に対して例えば丸鋸の平板状の刃を傾斜した一定角度に維持した状態で、板材を一定方向に送り出すだけで製造できるから、請求項5に比べ容易に製造することができる。
【0032】
請求項8に記載の発明によれば、予め平板材に切り出す方向と略直交方向の溝を形成しておくので、帯状材に分割された後に溝を形成する場合に比べ一度に加工できるから、水切り胴縁を容易かつ安価に製造することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a draining drum edge structure, a draining drum edge, and a manufacturing method thereof. For example, the present invention relates to a draining drum edge structure that serves as a base for an outer wall material such as a wooden building, a draining drum edge, and a manufacturing method thereof.
[0002]
[Background]
Conventionally, as shown in FIG. 9, the outer wall of a wooden building constructed by a panel method is provided with a panel 13 for a trunk edge base on the foundation of a building not shown, and a waterproof sheet 14 is provided on the entire surface of the outer wall. A plurality of rectangular trunk edges 90 are attached to the surface of the waterproof sheet 14 substantially horizontally, and a decorative panel 15 for finishing an outer wall such as a siding board is fixed thereon (for example, JP, 7-158181, A, etc.).
[0003]
[Problems to be solved by the invention]
However, in the above configuration, if rainwater enters the inside of the decorative panel 15, the trunk edge 90 has a rectangular cross section, and thus the rainwater that has entered may accumulate on the upper surface of the trunk edge 90.
[0004]
The objective of this invention is providing the draining drum edge structure with good drainage, the draining drum edge, and its manufacturing method.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the draining drum edge structure, draining drum edge and manufacturing method thereof according to the present invention adopt the following configuration.
The present invention will be described with reference to the drawings. The draining trunk edge structure according to claim 1 is a mounting surface on which a support surface 10A supported on the trunk edge base 13, an upper surface 10B on the upper side, and a wall surface material 15 are attached. In the draining trunk edge structure including the draining trunk edge 10 having 10C, the upper surface is inclined downward from either one of the mounting surface and the support surface toward the other surface 10C. A drainage channel for draining rainwater collected on the other surface side of the upper surface downward is formed between the other surface and the trunk base or the wall surface material facing the other surface. It is provided.
[0006]
According to the present invention, even if rainwater that has entered through the wall material flows down to the upper surface of the draining drum edge along the rear surface of the wall material, the rainwater flows on either the mounting surface or the support surface due to the gradient of the upper surface. Since it flows from the surface side to the other surface side and further drains downward through the drainage channel provided on the other surface side, the drainage can be improved. Therefore, since the wet state of the draining drum edge, the drum edge base and the wall surface material can be avoided, the durability is improved.
In particular, when the upper surface is provided with a gradient that slopes downward from the mounting surface side toward the support surface side, the wet state of the back surface of the wall material can be avoided, and the upper surface is directed from the support surface side to the mounting surface side. When a slope that slopes downward is provided, it is possible to avoid the wet state of the trunk base surface.
Here, the drainage channel may form a groove on the other surface of the draining barrel edge, but spacers are interposed at regular intervals between the other surface and the barrel edge base or wall material facing it. It may be configured.
[0007]
The draining drum edge according to claim 2, wherein the draining drum edge has a support surface supported by the trunk edge base, an upper surface which is an upper side, and a mounting surface to which a wall surface material is attached. And the gradient which inclines below toward the other surface side from any one surface side among the said support surfaces is formed, It is characterized by the above-mentioned.
According to the present invention, the drainage can be improved as in the first aspect.
[0008]
The draining drum edge according to claim 3 is characterized in that in the draining drum edge according to claim 2, a groove 11 in a direction substantially orthogonal to the longitudinal direction is formed on the other surface.
According to the present invention, the rainwater flowing down to the upper surface is drained downward through the groove provided on the other surface, so that the drainage can be improved as in the first aspect. Also, with this configuration, the number of parts can be reduced.
[0009]
The manufacturing method of the draining drum edge according to claim 4 prepares a plate material 30 equal to the thickness of the draining drum edge, and inserts a substantially triangular cross-sectional cut on the surface of the plate material in parallel with one side edge of the plate material, The plate material is divided into strip-shaped members 32 having a substantially trapezoidal cross section.
According to the present invention, the draining drum edge can be manufactured simply by applying a blade having a substantially triangular cross section of a circular saw, for example, from a direction substantially perpendicular to the surface of the flat plate material. Therefore, as compared with the case where the circular saw blade is applied at an angle inclined with respect to the surface, the circular saw blade can be processed accurately without being damaged, and thus the draining barrel edge can be easily manufactured.
[0010]
The manufacturing method of the draining drum edge of Claim 5 prepares the board | plate material 30 which is equal to the thickness of the draining drum edge, and it is parallel to the one side edge of a board | plate material so that a notch may be reversely reversed to the surface of the said board | plate material. And is divided into strip-shaped members 32 having a substantially trapezoidal cross section.
According to the present invention, the draining drum edge can be manufactured only by applying a flat blade of a circular saw, for example, at an angle inclined with respect to the surface of the flat plate material. Therefore, compared with the manufacturing method of the draining drum edge described in claim 4, the waste of material is less, so the draining drum edge can be manufactured at low cost.
[0011]
The method for manufacturing a draining drum edge according to claim 6 is the method for manufacturing a draining drum edge according to claim 4 or 5, wherein the both side cut portions are perpendicular to the longitudinal direction of the strip material inclined with respect to the surface. A strip is cut in the center of the direction in parallel with the cut portion, and the strip is divided into two parts.
According to this invention, it is possible to manufacture two draining drum edges simply by applying a flat blade of, for example, a circular saw from a substantially vertical direction to the surface of the belt-like material described in claim 4 or 5. Therefore, the draining drum edge can be manufactured easily and inexpensively.
[0012]
The manufacturing method of the draining drum edge according to claim 7 prepares a plate material 30 equal to the thickness of the draining drum edge, puts the cut on the surface of the plate material at an inclined angle and parallel to one side edge of the plate material, It is divided into strip-shaped members 32 having a substantially parallelogram cross section.
According to the present invention, for example, a plate material can be manufactured by simply feeding it in a fixed direction while maintaining a flat saw blade of a circular saw at a fixed angle with respect to the surface of the flat plate material. Can be manufactured.
[0013]
The method for manufacturing a draining cylinder edge according to claim 8 is the method for manufacturing a draining cylinder edge according to any one of claims 4 to 7, wherein the surface of the plate material is substantially orthogonal to the direction of cutting into the strip material in advance. A groove 11 in the direction is formed in advance.
According to this invention, since the grooves in the direction substantially perpendicular to the direction of cutting into the flat plate material are formed in advance, the grooves can be processed at a time as compared with the case where the grooves are formed after being divided into strip-shaped materials. And it can be manufactured at low cost.
[0014]

The gap may be formed and used as a drainage channel. In this way, rainwater that has flowed toward the mounting surface 10C due to the gradient of the upper surface 10B is drained downward through the drainage channel, so that drainage can be improved. Further, since the shape of the draining drum edge is simplified, the draining drum edge can be manufactured more easily and inexpensively.
[0024]
Moreover, in each embodiment, although the gradient which inclines below toward the attachment surface 10C side was formed in the upper surface 10B from the support surface 10A side, the gradient which inclines below toward the support surface 10A side from the attachment surface 10C side is formed. It may be formed. Even in this case, in addition to the effects (2) and (3) described in the first embodiment and the effect (4) described in the second embodiment, the following effects can be obtained.

Since the water is drained downward through the groove 11 formed on the surface 10A, the drainage can be improved. Therefore, since the wet state of the draining drum edge 10 and the back surface of the decorative panel 15 can be avoided, the durability is improved.
Moreover, since it is only necessary to change the angle at which the flat plate 30 is cut out in the manufacturing process, it can be easily manufactured and is inexpensive.
