Description

【０００１】
【発明の属する技術分野】
本発明は、建物躯体の窓開口部に取付けたサッシ窓下部の水切り構造に関する。
【０００２】
【従来の技術】
建物躯体の窓開口部にサッシ窓を取付けた場合に、そのサッシ窓に沿って流れ落ちた雨水等が建物外壁に流れ落ち、建物外壁が汚れることがある。
このために、サッシ窓の下部に水切り部材を取付け、その水切り部材を建物外壁よりも室外側に突出させることで、サッシ窓に沿って流れ落ちた雨水等が建物外壁に流れ落ちないようにしている。
【０００３】
例えば、図９と図１０に示すように建物躯体１の窓開口部２にサッシ窓３を取付け、このサッシ窓３の下枠４の下部に水切り部材５を取付け、その水切り部材５を建物外壁６よりも室外側に突出している。
【０００４】
【発明が解決しようとする課題】
水切り部材５の長手方向に沿って雨水等が流れ、水切り部材５の長手方向両端部から流れ落ちた雨水等は建物外壁６に沿って流れてしまうので、水切り部材５の長手方向両端部から雨水等が流れ落ちないようにする必要がある。
例えば、図９に示すようにサッシ窓３の縦枠７と建物外壁６の縦端面６ａとの間に充填するコーキング材８を図１０に示すように水切り部材５まで連続している。
【０００５】
しかしながら、下枠４は建物躯体１の室外面１ａよりも突出していると共に、その突出部分４ａと水切り部材５との間に形成される空間９の上下寸法が小さく、しかも空間９の奥行きが大きい（特に建物外壁が厚壁の場合には奥行きが大きい）ので、前述のコーキング材８を水切り部材５まで連続して下枠４の突出部分４ａと水切り部材５の長手方向両端部との間をコーキング材８でシールする作業が大変やりづらい。
【０００６】
そこで、本発明は前述の課題を解決できるようにしたサッシ窓下部の水切り構造を提供することを目的とする。
【０００７】
【課題を解決するための手段】
第１の発明は、建物躯体の窓開口部にサッシ窓を取付け、このサッシ窓の下部に水切り部材を取付けたサッシ窓の水切り構造であって、
前記水切り部材は、水切り本体の長手方向端部にキャップを取付けた形状で、
その水切り本体がサッシ窓の下枠の下部に水密して固着され、この水切り本体と下枠の突出部分との間に空間を有し、
前記キャップは、水切り本体に取付けられるキャップ本体と、このキャップ本体よりも上方に突出した側方立上り部を有し、
その側方立上り部が、サッシ窓の縦枠の面内方向外側の外面よりも面内方向外側寄り位置で、この側方立上り部の室内側部分は縦枠の外面と重なり合い、前記空間を側方立上り部の室内側部分で閉塞し、
前記建物躯体に取付けた建物外壁と前記側方立上り部の室内側部分との間及び、前記縦枠の外面と前記建物外壁との間を水密したことを特徴とするサッシ窓下部の水切り構造である。
【０００８】
第２の発明は、第１の発明において、前記側方立上り部の室内側部分と縦枠の外面との間を気密したサッシ窓下部の水切り構造である。
【０００９】
第３の発明は、第１又は第２の発明において、前記水切り本体は取付縦板と、この取付縦板の下部から室外側に向けて一体的に設けられた水切り板を有し、
前記キャップ本体は、前記水切り板の表面形状と略同一形状の横板と、この横板の室内側部に一体的に設けられ前記取付縦板の表面に接する縦板と、前記横板の裏面及び縦板の裏面に亘って一体的に設けた取付用縦片を有し、
前記水切り本体の長手方向端面が前記取付用縦片に水密材を介して連結され、前記縦板の裏面と前記側方立上り部の室内向縦面が水密材を介して建物躯体側に接して固着され、
前記各水密材が連続しているサッシ窓下部の水切り構造である。
【００１０】
第４の発明は、第１又は第２又は第３の発明において、前記側方立上り部の縦枠室外端部と対向した内向縦面は凹部を有する形状であるサッシ窓下部の水切り構造である。
【００１１】
第５の発明は、第１又は第２又は第３の発明において、前記側方立上り部は、その室内側部分が面内方向内側寄りで、室外側部分が面内方向外側寄りとなる平面略鉤形状であるサッシ窓下部の水切り構造である。
【００１２】
【作用】
第１の発明によれば、水切り本体の長手方向端部に設けたキャップの側方立上り部が縦枠の面内方向外側の外面よりも面内方向外側寄り位置で、この側方立上り部の室内側部分が縦枠の外面と重なり合って、下枠の突出部分と水切り本体との間の空間が側方立上り部の室内側部分で閉塞されているので、水切り本体の長手方向端部から雨水等が流れ落ちることがない。
また、縦枠の外面と建物外壁との間、建物外壁と側方立上り部の室内側部分との間を水密する時、例えば縦コーキング材を充填する時に、側方立上り部の室内側部分がコーキング受の役目をして水切り本体に縦コーキング材がはみ出すことがないので、前述の縦コーキングを充填する作業がやり易い。
【００１３】
第２の発明によれば、強風雨などで側方立上り部の室内側部分と縦枠の外面との間から雨水等の吹き上がりを防止し、水密性が向上する。
【００１４】
第３の発明によれば、水切り本体とキャップの連結部分が水密されるので、その部分から雨水等が流れ落ちることがない。また、キャップ本体の取付部分、側方立上り部の室内側部分の取付け部分が水密されるので、その部分から雨水等が建物躯体側に浸入することがない。
【００１５】
第４の発明によれば、室外端部に外向片を有する形状の縦枠の場合には、その外向片が凹部に突出するから外向片を有する形状の縦枠でも対応できる。
【００１６】
第５の発明によれば、室外端部に外向片を有する形状の縦枠の場合には、その外向片が側方立上り部の室外側部分と対向して外向片が側方立上り部と干渉しないので、外向片を有する形状の縦枠でも対応できる。
【００１７】
【発明の実施の形態】
図１に示すように、建物躯体１０の窓開口部１１にサッシ窓１２が取付けてある。
このサッシ窓１２を形成する下枠１３は、図１と図２に示すようにその面外方向中間部に設けられた躯体取付片１４を窓開口部１１の下開口縁室外面１１ａにビス１５で固着され、下枠１３の室外側部は下開口縁室外面１１ａよりも室外側に突出している。
前記サッシ窓１２を形成する縦枠１６は、図１と図３に示すようにその面外方向中間部に設けられた躯体取付片１７を窓開口部１１の縦開口縁室外面１１ｂにビス１８で固着され、縦枠１６の室外側部は縦開口縁室外面１１ｂよりも室外側に突出している。
前記サッシ窓１２を形成する上枠（図示せず）も前述と同様に取付けられる。
これによって、サッシ窓１２は半外付けサッシ窓となっている。
【００１８】
水切り部材２０は、図１に示すように水切り本体２１と、この水切り本体２１の長手方向両端部に取付けたキャップ２２より成る。このキャップ２２はサッシ窓１２の形状、取付け状態などによっては長手方向一端部に取付けても良い。
前記水切り本体２１は、取付縦板２３と、この取付縦板２３の下部と連続し室外側に向う水切り板２４で断面略Ｌ字形状である。前記水切り板２４は室内側部よりも室外側部が低くなるように傾斜している。
前記取付縦板２３が図１と図２に示すように下枠１３の躯体取付片１４の室外側面に水密材２５を介して接し、かつ前記ビス１５で固着してある。なお、取付縦板２３は建物躯体１０に固着しても良い。つまり建物躯体側に固着される。
このようであるから、水切り本体２１は下枠１３の下部に水密して固着され、下枠１３の突出部分１３ａは水切り板２４の上方に位置し、下枠１３の突出部分１３ａと水切り板２４（水切り本体２１）との間に空間を形成している。
【００１９】
前記キャップ２２は図４に示すように、板状のキャップ本体３０と、このキャップ本体３０の左右一端部と連続した側方立上り部４０より成る。
前記キャップ本体３０は水切り板２４の表面形状と略同一形状の横板３１と、この横板３１の室内側部と連続し前記取付縦板２３の表面形状と略同一形状の縦板３２で水切り本体２１の表面形状と略同一形状である。
前記横板３１の裏面全長と縦板３２の裏面下部寄りに亘って取付用縦片３３が一体的に設けてある。
この取付用縦片３３の左右一側面にシーラなどの水密材３４が接着して取付けられる。
【００２０】
前記側方立上り部４０は、横板３１の室外寄り部と連続した面外方向に向う第１縦板４１と、この第１縦板４１の室内側部と連続し、かつ横板３１の室内外側方向中間部と連続した面外方向に向う第２縦板４２と、この第２縦板４２の室内側部と連続し、かつ横板３１の室内側部及び縦板３２と連続した面外方向に向う第３縦板４３と、この第３縦板４３の室内側部と連続した面内方向に向う室内側縦板４４を有する。
【００２１】
前記第１縦板４１は短く横板３１の上面より若干突出している。
前記第２縦板４２は第１縦板４１よりも長く、図１に示すように縦枠１６の下端部よりも上方に突出している。この第２縦板４２は平面形状略内向きコ字状で内向縦面４２ａに凹部４５を形成し、その凹部４５は図３に示すように縦枠１６の室外端部と相対向している。
前記第３縦板４３は第２縦板４２よりも長く、図１に示すように縦枠１６の下端部よりも上方に突出している。前記室内側縦板４４は第３縦板４３と同一長さである。つまり、第２縦板４２と第３縦板４３は縦枠１６の外面に重なり合っている。
【００２２】
前記第３縦板４３の内向縦面４３ａの上部に逆流防止用の水密・気密材４６が接着してある。
前記室内側縦板４４の室内向縦面４４ａは前記縦板３２の裏面（室内側面）３２ａと面外方向に略面一に連続し、その室内向縦面４４ａと裏面３２ａ上部寄りに亘って水密材４７が接着して取付けられる。
この水密材４７と前記水密材３４は連続する。なお一体としても良い。
【００２３】
前記取付用縦片３３が水切り本体２１の長手方向端面に水密材３４を介して接し、この取付用縦片３３から水切り本体２１のビスホール２６にビスを螺合してキャップ本体３０は水切り本体２１の長手方向端部に水密して固着される。
図２に示すように、キャップ本体３０の横板３１が水切り本体２１の水切り板２４の表面に接して覆うと共に、キャップ本体３０の縦板３２が水切り本体２１の取付縦板２３の表面に接して覆う。
前述の各接触部分に浸入した雨水は、取付用縦片３３と水切り本体２１の端面の間が水密材３４で水密されているので、水切り本体２１の水切り板２４に沿って流れ落ちる。
【００２４】
前記第２縦板４２の室内側部分と第３縦板４３と室内側縦板４４（側方立上り部４０の室内側部分）が縦枠１６の面内方向外側の外面１６ａよりも面内方向外側寄り位置で、それらは縦枠１６の外面１６ａに重なり合う。
第３縦板４３の内向縦面４３ａが水密・気密材４６を介して縦枠１６の外面１６ａに接して水密・気密する。前記室内側縦板４４の室内向縦面４４ａが水密材４７を介して縦枠１６の躯体取付片１７の室外側面に接して水密すると共に、前記ビス１８で縦開口縁室外面１１ｂに固着する。この水密材４７の下部は前記水密材１４と連続する。なお、室内側縦板４４は縦枠形状が異なる場合等においては縦開口縁室外側面１１ｂに固着しても良い。つまり建物躯体側に固着する。
【００２５】
このようであるから、水切り本体２１の長手方向端部から雨水等が流れ落ちることがキャップ２２（側方立上り部４０）で阻止される。
また、水切り本体２１の取付部分が水密材１４で水密されているから、その取付部分から雨水等が建物躯体１０に浸入することがない。
【００２６】
また、キャップ２２のキャップ本体３０の取付部分（縦板３２の裏面と下開口縁室外面１１ａの間）は水密材４７で水密されていると共に、キャップ２２の側方立上り部４０の取付部分（室内側縦板４４の室内向縦面４４ａと縦枠１６の躯体取付片１７室外側の間）は水密材４７で水密されているので、キャップ２２の取付部分から雨水等が建物躯体１０に浸入しない。
【００２７】
また、キャップ２２の側方立上り部４０（第３縦板４３の内向縦面４３ａ）と縦枠１６の外面１６ａの間は、気密・水密材４６で気密・水密されているので、強風雨などで雨水等が側方立上り部４０（第３縦板４３）の上部を越えて縦枠１６の外面１６ａ側方向に吹き上がることがない。
特に、第３縦板４３は高く、その上端部に気密・水密材４６が設けてあるから、水切り本体２１から前記気密・水密部分までの上下寸法が大きく水密性が良い。なお、第３縦板４３（側方立上り部４０）の立上り寸法を大きくして縦枠１６の外面との重なり寸法（上下寸法）を大きくすれば、気密・水密材４６を用いなくとも吹き上げを防止できる。
【００２８】
前記キャップ２２の側方立上り部４０を形成する第２縦板４２の内向縦面４２ａは凹部４５を形成しているので、図３に示すように縦枠１６の室外寄りに一体的に設けた外向片１９が凹部４５に突出し、側方立上り部４０（第３縦板４３の内向縦面４３ａ）と縦枠１６の外面１６ａとの間に所定寸法の隙間を形成できる。
【００２９】
次に建物外壁との水密について説明する。
図１に示すように建物躯体１０の室外面に建物外壁５０が取付けられる。
前記建物外壁５０の上端面５０ａと水切り本体２１の水切り板２４室外側部の裏面との間が図１と図２に示すように横コーキング材５１で水密される。
前記建物外壁５０の縦端面５０ｂと縦枠１６の外面１６ａとの間は図１と図３に示すように縦コーキング材５２で水密される。
この縦コーキング材５２を充填する時にキャップ２２の側方立上り部４０（第２縦板４２）がコーキング受けの役目をするので、その縦コーキング材５２を容易に充填できる。
【００３０】
前記横コーキング材５１と縦コーキング材５２は図５に示すように連続する。
また、窓開口部１１の下縁に沿って取付けた建物外壁５０と窓開口部１１の縦縁に沿って取付けた建物外壁５０の間には図５に示すように縦目地５３が形成してある。
この縦目地５３に前述の縦コーキング材５１が連続して充填される。
【００３１】
図６と図７は第２の実施の形態を示し、サッシ枠１２を形成する下枠１３、縦枠１６が嵌め殺しサッシ窓を形成する断面形状で、縦枠１６の外向片１９が長い。
水切り部材２０は前述と同一形状で、縦枠１６の外向片１９がキャップ２２の側方立上り部４０を形成する第２縦板４２の凹部４５に突出している。
【００３２】
図８は第３の実施の形態を示し、側方立上り部４０を、第１縦板４１と第２縦板４２（室外側部分）が面内方向外側で、第３縦板４３（室内側部分）が面内方向内側となるように平面略鉤形状としてある。
このようにすれば、縦枠１６の外向片１９が第２縦板４２と対向して干渉しないので、縦枠１６の外面１６ａと第３縦板４３との間の寸法を外向片１９を備えていない縦枠と同一とすることができる。
【００３３】
【発明の効果】
請求項１に係る発明によれば、水切り本体の長手方向端部に設けたキャップの側方立上り部が縦枠の面内方向外側の外面よりも面内方向外側寄り位置で、この側方立上り部の室内側部分が縦枠の外面と重なり合って、下枠の突出部分と水切り本体との間の空間が側方立上り部の室内側部分で閉塞されているので、水切り本体の長手方向端部から雨水等が流れ落ちることがない。
また、縦枠の外面と建物外壁との間、建物外壁と側方立上り部の室内側部分との間を水密する時、例えば縦コーキング材を充填する時に、側方立上り部の室内側部分がコーキング受の役目をして水切り本体に縦コーキング材がはみ出すことがないので、前述の縦コーキングを充填する作業がやり易い。

BACKGROUND OF THE INVENTION
The present invention relates to a draining structure under a sash window attached to a window opening of a building frame.
[0002]
[Prior art]
When a sash window is attached to the window opening of the building frame, rainwater or the like that has flowed down along the sash window may flow down to the building outer wall, and the building outer wall may become dirty.
For this purpose, a draining member is attached to the lower part of the sash window, and the draining member is protruded to the outside of the building outside the outer wall of the building so that rainwater or the like that has flowed down along the sash window does not flow down to the outer wall of the building.
[0003]
For example, as shown in FIGS. 9 and 10, a sash window 3 is attached to the window opening 2 of the building housing 1, and a draining member 5 is attached to the lower part of the lower frame 4 of the sash window 3. It protrudes to the outdoor side rather than 6.
[0004]
[Problems to be solved by the invention]
Rainwater and the like flow along the longitudinal direction of the draining member 5, and rainwater and the like flowing down from both ends in the longitudinal direction of the draining member 5 flows along the building outer wall 6. It is necessary to prevent it from flowing down.
For example, as shown in FIG. 9, the caulking material 8 filled between the vertical frame 7 of the sash window 3 and the vertical end surface 6a of the building outer wall 6 is continued to the draining member 5 as shown in FIG.
[0005]
However, the lower frame 4 protrudes from the outdoor surface 1a of the building housing 1, and the vertical dimension of the space 9 formed between the protruding portion 4a and the draining member 5 is small, and the depth of the space 9 is large. (In particular, when the building outer wall is a thick wall, the depth is large.) Therefore, the caulking material 8 is continuously extended to the draining member 5 between the protruding portion 4a of the lower frame 4 and both longitudinal ends of the draining member 5. The work of sealing with the caulking material 8 is very difficult.
[0006]
Accordingly, an object of the present invention is to provide a draining structure under a sash window that can solve the above-described problems.
[0007]
[Means for Solving the Problems]
The first invention is a sash window draining structure in which a sash window is attached to a window opening of a building frame, and a draining member is attached to the lower part of the sash window,
The draining member has a shape with a cap attached to the longitudinal end of the draining body,
The draining body is fixed tightly to the lower part of the lower frame of the sash window, and there is a space between the draining body and the protruding part of the lower frame,
The cap has a cap body attached to the draining body, and a side rising part protruding upward from the cap body,
The side rising portion is located closer to the outside in the in-plane direction than the outer surface outside the in-plane direction of the vertical frame of the sash window, and the indoor side portion of the side rising portion overlaps with the outer surface of the vertical frame, and the space Block at the indoor side of the rising part,
A draining structure at the lower part of the sash window, characterized in that the space between the building outer wall attached to the building frame and the indoor side portion of the side rising portion and between the outer surface of the vertical frame and the building outer wall are watertight. is there.
[0008]
According to a second aspect of the present invention, in the first aspect of the present invention, there is provided a draining structure for the lower portion of the sash window in which the space between the indoor side portion of the side rising portion and the outer surface of the vertical frame is airtight.
[0009]
A third invention is the first or second invention, wherein the draining body has a mounting vertical plate and a draining plate integrally provided from the lower part of the mounting vertical plate toward the outdoor side,
The cap body includes a horizontal plate having substantially the same shape as the surface shape of the draining plate, a vertical plate integrally provided on the indoor side portion of the horizontal plate and in contact with the surface of the mounting vertical plate, and a rear surface of the horizontal plate. And a mounting vertical piece provided integrally over the back surface of the vertical plate,
A longitudinal end surface of the draining main body is connected to the mounting vertical piece via a water-tight material, and a rear surface of the vertical plate and a vertical surface facing the interior of the side rising portion are in contact with the building frame side via the water-tight material. Fixed,
It is the draining structure of the lower part of the sash window where each said watertight material is continuing.
[0010]
4th invention is the draining structure of the lower part of a sash window which is a shape which the inward vertical surface facing the vertical frame chamber outer end part of the said side rising part has a recessed part in 1st, 2nd or 3rd invention. .
[0011]
According to a fifth invention, in the first, second, or third invention, the laterally rising portion has a substantially planar surface in which the indoor side portion is closer to the inner side in the in-plane direction and the outdoor side portion is closer to the outer side in the in-plane direction. It is a draining structure at the bottom of the sash window that has a bowl shape.
[0012]
[Action]
According to the first aspect of the present invention, the side rising portion of the cap provided at the longitudinal end of the draining main body is located closer to the outside in the in-plane direction than the outer surface in the in-plane direction of the vertical frame. Since the indoor side part overlaps with the outer surface of the vertical frame, the space between the protruding part of the lower frame and the draining body is blocked by the indoor side part of the side rising part, so rainwater starts from the longitudinal end of the draining body. Etc. will not flow down.
Also, when watertight between the outer surface of the vertical frame and the building outer wall , between the building outer wall and the indoor side portion of the side rising part, for example, when filling the vertical caulking material, the indoor side part of the side rising part is Since the vertical caulking material does not protrude from the draining body in the role of receiving the caulking, the work of filling the above-mentioned vertical coking is easy.
[0013]
According to the second aspect of the present invention, rainwater or the like is prevented from blowing up between the indoor side portion of the side rising portion and the outer surface of the vertical frame due to strong wind and rain, and water tightness is improved.
[0014]
According to the third aspect of the invention, the connecting portion between the draining main body and the cap is watertight, so that rainwater or the like does not flow down from that portion. In addition, since the mounting portion of the cap body and the mounting portion of the indoor side portion of the side rising portion are watertight, rainwater or the like does not enter the building frame from that portion.
[0015]
According to the fourth aspect of the invention, in the case of a vertical frame having an outward piece at the outdoor end, the outward piece protrudes into the recess, so that a vertical frame having an outward piece can be used.
[0016]
According to the fifth invention, in the case of a vertical frame having an outward piece at the outdoor end, the outward piece opposes the outdoor part of the side rising part and the outward piece interferes with the side rising part. Therefore, even a vertical frame having an outwardly facing piece can be used.
[0017]
