Description
【０００１】
【発明の属する技術分野】
この発明は、マンサード屋根における腰折れ部分の水切装置に関するものである。
【０００２】
【従来の技術】
マンサード屋根においては、上部側の緩勾配部分に敷設した屋根葺材と、下側の急勾配部分に敷設した屋根葺材とを連続して設けることが出来ない。この場合、屋根葺材の下側には、アスファルトルーフィングなどの防水シートが設けられているが、これだけでは、充分な防水構造が得られない欠点がある。
【０００３】
【発明が解決しようとする課題】
この発明は、このようなマンサード屋根の腰折れ部において、充分な防水効果を備えるとともに、外観に優れた水切装置を提供することを目的とするものである。
【０００４】
【課題を解決するための手段】
上記の課題を解決するため、この発明では、まず、傾斜屋根の傾斜方向の中間部が腰折れ形に折れ曲がったマンサード屋根において、前記腰折れ部に沿ってくの字型に折れ曲がった水切材本体が、同じく腰折れ部を挟んだ上下の野地板間に跨るようにして取り付けられる。
【０００５】
そして、水切材本体には、腰折れ部よりも下側部分の上面に、その稜線が水平方向となるように断面が山形となった外側水切がその上端部分で連設されて設けられ、それら外側水切と水切材本体との間に、板状屋根葺材の上端が下側から差し込まれていることを特徴とするものである。
【０００６】
【発明の実施の形態】
図１は、住宅のマンサード屋根を示し、屋根面の軒先方向の中間部分が腰折れ状に折れ曲がって、この腰折れ部を介して棟側の緩勾配の屋根面（１）と軒側の急勾配の屋根面（２）とに分かれている。そして、この腰折れ部に沿ってこの発明の水切材（３）が、桁行方向に取りつけられている。
【０００７】
図２は、前記腰折れ部分での屋根部の断面を示し、腰折れ部を挟んだ上下の屋根フレーム（４）（５）の上面に金具（６）（６）を介して木製の母屋（７）が固定され、この母屋（７）の上に野地板（８）（８）が張りつけられている。（９）は、野地板（８）（８）の上面にまたがって敷かれたアスファルトルーフィングを示している。
【０００８】
そして、このアスファルトルーフィング（９）の上に、同じく腰折れ部を挟んだ上下の野地板（８）（８）間に跨るようにして、前記の水切材（３）のくの字型の本体（１４）が取りつけられている。この本体（１４）の腰折れ部よりも上部側は、一旦上方へ鉤型に折り曲げ（１０）された後上方へ延び、更にその上端部が上面側へ斜めに折り返し（１１）された後上方へ折曲されて、その先端部において釘打ち（１２）されている。この上部部分には、図３のように、水切材本体（１４）の上から更にアスファルトルーフィングが（１３）が敷かれている。
【０００９】
他方、水切材本体(14)の腰折れ部よりも下側部分には、その上面に、腰折れ部に水平方向のシャープな稜線を現出させるよう断面が山形となった外側水切(15)が、その上端部分で連設されて設けられており、この外側水切(15)の山部の内側に、角木材からなる下地材(16)が差し込まれて、外側から打ち込んだ釘(17)で野地板(８)へ固定されている。
【００１０】
この下地材（１６）の下部側において、板状屋根葺材（１８）の上端が外側水切（１５）と水切材本体（１４）との間に、下側から差し込まれている。また、外側水切（１５）の下端が屋根葺材（１８）の上面において内側へ折り返し（２１）されている。他方、腰折れ部よりも上部側のアスファルトルーフィング（１３）の上面にも屋根葺材（２０）が設置されている。図３の（２２）は、屋根の妻側の端部に取り付けられるけらば水切である。
【００１１】
【発明の効果】
以上のように、この発明では、腰折れ部よりも下側部分の上面に、その稜線が水平方向となるように断面が山形となった外側水切がその上端部分で連設されて設けられ、それら外側水切と水切材本体との間に、板状屋根葺材の上端が下側から差し込まれているので、この部分の防水性が良好となる効果がある。しかも、この外側水切りの山形部の稜線により、屋根の外観にシャープさを持たせることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a draining device for a folded back portion of a mansard roof.
[0002]
[Prior art]
In the mansard roof, it is not possible to continuously provide the roof covering material laid in the upper part of the gentle slope and the roof covering material laid in the lower steep part. In this case, a waterproof sheet such as asphalt roofing is provided on the lower side of the roof covering material, but there is a drawback that a sufficient waterproof structure cannot be obtained by this alone.
[0003]
[Problems to be solved by the invention]
An object of the present invention is to provide a draining device that has a sufficient waterproof effect and has an excellent appearance at the waist folding portion of such a mansard roof.
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, in this invention, first, in the mansard roof where the middle part of the inclined direction of the inclined roof is bent into a fold-back shape, the draining material main body bent into a dogleg shape along the fold-back portion is the same. It is attached so as to straddle between the upper and lower field boards across the hip folding part.
[0005]
Further, the drainage body is provided with an outer drainage having a mountain-shaped cross-section so that the ridge line is in the horizontal direction on the upper surface of the lower part than the waist folding part, and the outer side of the outer drainage is provided outside these parts. The upper end of the plate-like roofing material is inserted from the lower side between the drainer and the drainer main body.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Fig. 1 shows a mansard roof of a house, where the middle part of the roof surface in the direction of the eaves is bent into a waist fold, and the ridge side of the roof surface (1) and the eaves side of the steep slope are bent through this waist fold. It is divided into a roof surface (2). And the draining material (3) of this invention is attached to the column direction along this waist folding part.
[0007]
FIG. 2 shows a cross section of the roof portion at the waist folding portion, and a wooden purlin (7) on the upper surfaces of the upper and lower roof frames (4) and (5) sandwiching the waist folding portion via metal fittings (6) and (6). Is fixed, and the base plate (8) (8) is stuck on this main building (7). (9) shows the asphalt roofing laid across the upper surface of the base plate (8) (8).
[0008]
And, on this asphalt roofing (9), it is straddled between the upper and lower field boards (8) and (8) that sandwich the hip folding part, and the above-mentioned draining material (3) has a U-shaped body ( 14) is attached. The upper side of the body (14) is folded upward (10) and then extended upward, and the upper end of the body (14) is folded upward (11) obliquely upward (11) and then upward. It is bent and nailed (12) at its tip. As shown in FIG. 3, asphalt roofing (13) is further laid on the upper portion from above the draining body (14).
[0009]
On the other hand, in the lower portion than the buckling portion of the water-shielding material body (14), on its upper surface, the outer draining (15) the cross section becomes a mountain shape so as to revealing a sharp ridge in the horizontal direction buckling portion The base material (16) made of square timber is inserted inside the mountain part of the outer drainer (15) and is driven from the outside with a nail (17). It is fixed to the field plate (8).
[0010]
On the lower side of the base material (16), the upper end of the plate roofing material (18) is inserted from the lower side between the outer draining body (15) and the draining body body (14). Further, the lower end of the outer drainer (15) is folded back (21) inwardly on the upper surface of the roof covering material (18). On the other hand, the roof covering material (20) is also installed on the upper surface of the asphalt roofing (13) on the upper side of the folded back part. (22) of FIG. 3 is a drainer if it is attached to the end of the roof side of the wife.
[0011]
【The invention's effect】
As described above, in the present invention, on the upper surface of the lower part from the waist folded part , the outer drainer having a mountain-shaped cross-section so that the ridge line is in the horizontal direction is provided continuously at the upper end part thereof, Since the upper end of the plate-like roof covering material is inserted from the lower side between the outer draining body and the draining body main body, there is an effect that the waterproofness of this portion is improved. In addition, the ridgeline of the mountain-shaped portion of the outside draining can give the roof appearance sharpness.
