特開２００９−２２１８１６号公報JP 2009-221816 A

在来浴室をシステムバスに改良する際に、在来浴室に既設の浴室サッシがある場合には、その既設の浴室サッシを新設の浴室サッシに改装するが、既設の浴室サッシが大きく、浴室サッシの下部分がシステムバスの浴槽（つまり、新設する浴槽）よりも下に位置することがあり、その既設の浴室サッシの既設枠に新設枠を取り付けて新設の浴室サッシとすると、新設の浴室サッシにおける浴槽よりも下の部分から浴槽の熱が室外に逃げ易く、浴槽内の温度低下を招くことになるばかりか、浴室サッシ周りの納まり、止水が複雑になり施工性が悪い。 When upgrading a conventional bathroom to a system bath, if there is an existing bathroom sash in the conventional bathroom, the existing bathroom sash is renovated to a new bathroom sash, but the existing bathroom sash is large and the bathroom sash is large. The lower part of the tub may be located below the bathtub of the system bath (that is, the bathtub to be newly installed). If a new frame is attached to the existing frame of the existing bathroom sash, a new bathroom sash is obtained. The heat of the bathtub easily escapes from the lower part of the bathtub to the outside of the room, resulting in a decrease in the temperature in the bathtub, and the housing sash is complicated and the water stop is complicated, and the workability is poor.

これらのことから、前述のように大きな既設の浴室サッシの場合には、既設の浴室サッシの既設枠が取り付けてある外壁、躯体の開口部の大きさを小さくし、新設の浴室サッシの新設枠を既設枠より小さくして新設の浴室サッシがシステムバスの浴槽よりも下となる部分を有しないようにしている。
しかしながら、前述のようにすると外壁・躯体工事を必要とするので、工期、費用が膨大なものとなる。 Therefore, in the case of a large existing bathroom sash as described above, the size of the outer wall to which the existing frame of the existing bathroom sash is attached and the size of the opening of the housing are reduced, and the new frame of the new bathroom sash is installed. Is smaller than the existing frame so that the new bathroom sash does not have a portion below the bathtub of the system bath.
However, as described above, since the outer wall and the frame work are required, the construction period and costs become enormous.

本発明は、前述の課題に鑑みなされたものであり、その目的は、新設する浴槽よりも下に位置する下方開口部分を有した既設サッシを、外壁・躯体工事をせずに浴槽の熱が室外に逃げることを抑制できる新設の浴室サッシに改装できるようにした浴室改装サッシとすることである。 The present invention has been made in view of the above-described problems, and the purpose of the present invention is to heat an existing sash having a lower opening portion located below a newly-installed bathtub without performing outer wall / frame construction. A bathroom renovation sash that can be refurbished into a new bathroom sash that can prevent escape to the outdoors.

本発明は、既設サッシの既設枠の開口内に新設サッシの新設枠を取り付けた浴室改装サッシであって、
前記既設枠は、新設する浴槽の上部よりも下方の下方開口部分を有し、
前記新設サッシは、既設枠の下方開口部分に取り付ける下部新設サッシと、既設枠の下方開口部分以外の上方開口部分に取り付ける上部新設サッシを備え、
前記下部新設サッシは、下部新設枠に断熱パネルを設けたものとし、
前記上部新設サッシは、上部新設枠に透光性面材を設けたものであることを特徴とする浴室改装サッシである。 The present invention is a bathroom remodeling sash in which a new frame of a new sash is attached within an opening of an existing frame of an existing sash,
The existing frame has a lower opening part below the upper part of the newly installed bathtub,
The new sash includes a lower new sash attached to a lower opening portion of an existing frame, and an upper new sash attached to an upper opening portion other than the lower opening portion of the existing frame,
The lower new sash is provided with a heat insulation panel on the lower new frame,
The upper new sash is a bathroom refurbishment sash in which a translucent surface material is provided on an upper new frame.

本発明においては、前記上部新設枠の室内側部に額縁を四周連続して室内側に向けて取り付け、
この額縁と前記浴槽とに渡って内装材を取り付け、
前記上部新設枠の上部新設下枠の室内側部にアタッチメントを室内側に向けて取り付け、このアタッチメントで前記額縁を支持するようにできる。
このようにすれば、額縁と内装材とで室内から既設枠が見えないので、見栄えが良い。
また、浴槽の熱が額縁から上部新設枠を伝わって室外に伝わり難い。
また、額縁をアタッチメントで支持するから、額縁をしっかりと支持することができる。 In the present invention, a frame is attached to the indoor side of the upper newly installed frame continuously four times toward the indoor side,
Attaching the interior material over this frame and the bathtub,
An attachment can be attached to the indoor side of the upper newly installed lower frame of the upper newly installed frame so as to face the indoor side, and the frame can be supported by this attachment.
In this way, since the existing frame cannot be seen from the room with the frame and the interior material, the appearance is good.
Moreover, it is difficult for the heat of the bathtub to be transmitted from the frame through the upper new frame to the outside.
Further, since the frame is supported by the attachment, the frame can be firmly supported.

本発明においては、前記アタッチメントは、室内側支持部と中間下向き傾斜部と室内側取付部を有し、その室内側取付部を上部新設下枠の室内側に固着することで、室内側支持部が室内側に向かい、かつ中間下向き傾斜部が上部新設下枠と額縁の連結部の下方に位置するように取り付け、
前記上部新設下枠の下部に無目を取り付け、その無目の下部に下部新設枠の下部新設上枠を取り付け、
前記上部新設下枠の室内側部におけるアタッチメントの取付部分よりも上方に排水穴を形成し、この排水穴を上部新設下枠と無目との間の排水通路を経て下部新設上枠の室外側上面に連通するようにできる。
このようにすれば、上部新設下枠と額縁の連結部などから額縁の下に洩れた水がアタッチメントの中間下向き傾斜部に落下し、排水穴、排水通路を経て下部新設上枠の上面から室外に排水することができる。 In the present invention, the attachment includes an indoor side support portion, an intermediate downward inclined portion, and an indoor side attachment portion, and the indoor side attachment portion is fixed to the indoor side of the upper newly installed lower frame, thereby the indoor side support portion. Is attached so that it faces the indoor side and the middle downward inclined part is located below the connection part of the upper newly installed lower frame and the frame,
Attached to the lower part of the upper new lower frame, the lower new upper frame of the lower new frame is attached to the lower part of the lower part,
A drainage hole is formed above the attachment part of the attachment on the indoor side of the upper new lower frame, and this drainage hole passes through the drainage passage between the upper new lower frame and the eyelet and is outside the lower new upper frame. It can communicate with the top surface.
In this way, water that leaks from the connecting part of the upper new lower frame and the frame to the lower part of the frame falls to the middle downward inclined part of the attachment, passes through the drainage hole and drainage passage, and passes from the upper surface of the lower new upper frame to the outdoor. Can be drained.

本発明においては、前記上部新設下枠と無目との間を水密する水密材の長手方向端部と端部水密材を離隔して排水路を形成すると共に、無目の室外側寄りに室外側排水穴を下部新設上枠の上面と対向して形成することで、排水通路とし、
前記無目と下部新設上枠の上面との間における室外側排水穴よりも室内側寄りを水密材で水密することができる。
このようにすれば、上部新設下枠と額縁の連結部などから額縁の下に洩れた水を確実に室外に排水できる。 In the present invention, a drainage channel is formed by separating the longitudinal end portion of the watertight material and the end watertight material which are watertight between the upper newly installed lower frame and the seamless, and the chamber is located near the unsightly outdoor side. By forming the outer drainage hole facing the upper surface of the lower new upper frame, it becomes a drainage passage,
It is possible to water-tighten the indoor side closer to the indoor side than the outdoor drainage hole between the seamless and the upper surface of the lower new upper frame with a watertight material.
If it does in this way, the water which leaked under the frame from the connection part of an upper newly established lower frame, a frame, etc. can be reliably drained outside.

本発明によれば、新設する浴槽と対向した部分が断熱パネルを有した下部新設サッシであるから、浴槽の熱が室外に逃げることを抑制できる。
しかも、既設サッシの既設枠の下方開口部分を下部新設サッシで覆うようにしたから、外壁・躯体工事をする必要がなく、工期を短縮できると共に、費用を低減できる。 According to this invention, since the part facing the newly installed bathtub is a lower newly installed sash having a heat insulating panel, the heat of the bathtub can be prevented from escaping to the outside.
Moreover, since the lower opening portion of the existing frame of the existing sash is covered with the lower new sash, it is not necessary to carry out the outer wall / frame construction, the construction period can be shortened and the cost can be reduced.

Since water may flow down under the lower frame 24 and adhere to the bathtub 6, the water that has flowed down under the lower frame 24 can be drained from the new frame to the outside of the room.

すなわち、図６に示すように上部新設下枠２１と下額縁２４との連結部から洩れた水がアタッチメント７の室外側板７２（中間下向き傾斜部）に流れ落ちるようにする。
アタッチメント７の室外側縦板７３と上部新設下枠２１の室内側部との連結部を水密材８０で水密し、前述の室外側縦板７２に流れ落ちた水がアタッチメントの取付部から落下しないようにすると共に、上部新設下枠２１のアタッチメント取付部の上方に排水穴８１を形成する。 That is, as shown in FIG. 6, the water leaked from the connecting portion between the upper newly installed lower frame 21 and the lower frame 24 is allowed to flow down to the outdoor side plate 72 (intermediate downward inclined portion) of the attachment 7.
The connecting portion between the outdoor vertical plate 73 of the attachment 7 and the indoor side portion of the upper newly installed lower frame 21 is watertight with a watertight material 80 so that the water that has flowed down to the outdoor vertical plate 72 does not fall from the attachment portion of the attachment. In addition, a drainage hole 81 is formed above the attachment mounting portion of the upper newly installed lower frame 21.

上記新設下枠２１と無目３３との間に、前述の排水穴８１を下部新設上枠３０の上面まで連続する排水通路を形成する。
例えば、上部新設下枠２１の下部と無目３３の上部との間を水密する水密材８２を、図１０に示すように長手方向両端部に設けないようにすると共に、端部水密材８３を設け、その端部水密材８３と水密材８２の端部との間に排水路８４を形成し、前述の排水穴８１から流れ落ちた水が排水路８４を通して無目３３の室外側上面に流れるようにする。 A drainage passage that continues the drainage hole 81 to the upper surface of the lower new upper frame 30 is formed between the new lower frame 21 and the mesh 33.
For example, the watertight material 82 for watertightness between the lower part of the upper newly installed lower frame 21 and the upper part of the mesh 33 is not provided at both ends in the longitudinal direction as shown in FIG. And a drainage channel 84 is formed between the end watertight material 83 and the end of the watertight material 82 so that the water flowing down from the drainage hole 81 flows through the drainage channel 84 to the upper surface of the outdoor side of the joint 33. To.

そして、無目３３の室外側部に室外側排水穴８５を形成して前述の水が室外側排水穴８５から下部新設上枠３０の室外側上面に流れるようにすると共に、下部新設上枠３０の室内寄り上面と無目３３の下面との間を水密材８６で水密し、前述の水が下部新設上枠３０の上面から室外側に排水されるようにする。
この実施の形態では、下部新設上枠３０の室外側寄りの上面を水平に対して室外側が室内側よりも低くなるように傾斜（つまり水勾配）させてある。 Then, an outdoor drain hole 85 is formed in the outdoor portion of the seamless 33 so that the above-mentioned water flows from the outdoor drain hole 85 to the outdoor upper surface of the lower new upper frame 30 and the lower new upper frame 30. The water-tight material 86 is used to seal the space between the upper surface close to the indoor side and the lower surface of the mesh 33 so that the water is drained from the upper surface of the lower new upper frame 30 to the outdoor side.
In this embodiment, the upper surface near the outdoor side of the lower new upper frame 30 is inclined (that is, water gradient) so that the outdoor side is lower than the indoor side with respect to the horizontal.

前述の実施の形態は、在来浴室をユニットバスなどに改装するようにしたが、浴室ではない室にユニットバスを設置して浴室とする場合にも応用できることは勿論である。
また、ジョイント枠４を用いずに上部新設枠２ａ、下部新設枠３ａを既設枠１の開口内に取り付けることも可能である。 In the above-described embodiment, the conventional bathroom is remodeled into a unit bath or the like, but it is needless to say that the present invention can be applied to a case where a unit bath is installed in a room other than the bathroom.
Further, it is possible to attach the upper new frame 2 a and the lower new frame 3 a in the opening of the existing frame 1 without using the joint frame 4.
