Description

本発明は、上下に二枚の障子を備える上げ下げ窓に関する。 The present invention relates to a raising / lowering window having two shoji screens on the upper and lower sides.

従来、外障子と内障子を備え、少なくとも内障子が上下動自在な上げ下げ窓があり（外障子は上下動自在なもの（内障子と連動するものも含む）と固定されているものがある）、建築物の躯体に取り付けられる場合や、ドアに取り付けられる場合がある。図８に示すのはその一例であり、ドアの中央に開口部を形成してあって、外障子１０２ａ及び内障子１０２ｂを上下動自在に取り付けてある（外障子１０２ａと内障子１０２ｂは連動する）。閉鎖時において、外障子１０２ａは上側、内障子１０２ｂは下側となる。ここで内障子１０２ｂに着目すると、図７に示すように、閉鎖時において、内障子１０２ｂの下框１２２ｂは下枠１１２に設けたタイト材１１６に当接するものであって、室外側に垂下片１３１を有している。この垂下片１３１は、室外側からの雨水の浸入を防ぐものであり、左右端には樹脂製のキャップ１３０ａを取り付けてある。この樹脂製のキャップ１３０ａには、外障子１０２ａと内障子１０２ｂを連動させるためのワイヤ１３０が接続される。 Conventionally, there are external and internal shojis, and at least there is a raising and lowering window that allows the internal reciprocating elements to move up and down. In some cases, it may be attached to a building frame or to a door. An example is shown in FIG. 8, and an opening is formed in the center of the door, and the external shoji 102a and the internal shoji 102b are attached to be movable up and down (the external shoji 102a and the internal shoji 102b are interlocked with each other). ). At the time of closing, the outer shoji 102a is on the upper side and the inner shoji 102b is on the lower side. Here, when focusing on the inner impingement 102b, as shown in FIG. 7, when closed, the lower arm 122b of the inner impingement 102b comes into contact with the tight material 116 provided on the lower frame 112, 131. The drooping piece 131 prevents rainwater from entering the outside of the room, and resin caps 130a are attached to the left and right ends. The resin cap 130a is connected to a wire 130 for interlocking the external obstacle 102a and the internal obstacle 102b.

しかしながら、このような従来の上げ下げ窓が火災時に炎にさらされると、下框１２２ｂの左右端の樹脂製のキャップ１３０ａが溶け、縦枠１１３と下框１２２ｂの間に隙間が生じて炎が侵入する。そして、下枠１１２や下框１２２ｂに熱伸びやガタツキが生じ、さらにタイト材１１６が溶けることで、下枠１１２と下框１２２ｂの間に隙間が生じて室内外が連通し、延焼につながるおそれがあった。 However, when such a conventional raising / lowering window is exposed to a flame in the event of a fire, the resin caps 130a on the left and right ends of the lower rod 122b melt, creating a gap between the vertical frame 113 and the lower rod 122b, and the flame enters. To do. Then, thermal expansion or rattling occurs in the lower frame 112 and the lower rod 122b, and further, the tight material 116 is melted, so that a gap is generated between the lower frame 112 and the lower rod 122b, and indoors and outdoors may be connected, leading to fire spread. was there.

At the time of closing, the outer shoji 2a is on the upper side and the inner shoji 2b is on the lower side. The crescent lock 20 is provided on the upper side of the upper collar 21b of the inner limb 2b and can be locked when closed. In addition, each frame and each collar are made of an aluminum member on the outdoor side and a resin member on the indoor side.

より詳しくは、図６に示すように、左右の縦枠１３の内周側端部の室外側には、室外側に延びる外周側面と外周側面の室外側端部から内周側に延びる室外側面からなる持出部１３ａを形成してあり、この持出部１３ａにより、縦枠１３の内周側端部の見込幅が広くなっている。そして、縦枠１３（及び持出部１３ａ）の内周側には、上下に延びる２本のガイド溝１４ａ，１４ｂが並んで形成してある。ガイド溝１４ａ，１４ｂは断面略コ字形で、室外側のガイド溝１４ａは持出部１３ａ部分に形成してある。そして室外側のガイド溝１４ａには外障子２ａの左右端（縦框２３ａ）が納まり、室内側のガイド溝１４ｂには内障子２ｂの左右端（縦框２３ｂ）が納まっていて、外障子２ａ及び内障子２ｂは上下動自在となっている。なお、この外障子２ａと内障子２ｂはワイヤ３０により連結されていて連動するようになっており、一方の障子を動かすと、他方の障子が反対方向に同距離だけ動く。また、図５に示すように、上枠１１の内周側（下側）端部の室外側にも、縦枠１３と同様に外周側面と室外側面からなる持出部１１ａを形成してあり、外障子２ａの閉鎖状態において、外障子２ａの上端（上框２１ａ）が納まる。さらに、下枠１２の内周側（上側）端部の室外側には、室外側に延びる延出片１２ａを形成してある。 More specifically, as shown in FIG. 6, on the outdoor side of the inner peripheral side end portions of the left and right vertical frames 13, an outer peripheral side surface extending to the outdoor side and an outdoor side surface extending from the outdoor side end portion of the outer peripheral side surface to the inner peripheral side. The carrying-out part 13a which consists of this is formed, The expected width | variety of the inner peripheral side edge part of the vertical frame 13 is widened by this carrying-out part 13a. Two guide grooves 14a and 14b extending vertically are formed side by side on the inner peripheral side of the vertical frame 13 (and the take-out portion 13a). The guide grooves 14a and 14b have a substantially U-shaped cross section, and the guide groove 14a on the outdoor side is formed in the take-out portion 13a. The left and right ends (vertical rods 23a) of the outer obstacle 2a are accommodated in the outdoor guide groove 14a, and the left and right ends (vertical rods 23b) of the inner obstacle 2b are accommodated in the indoor guide groove 14b. And the inner shoji 2b is movable up and down. The outer shoji 2a and the inner shoji 2b are connected by a wire 30 so as to be interlocked. When one shoji is moved, the other shoji moves in the opposite direction by the same distance. Further, as shown in FIG. 5, a take-out portion 11 a composed of an outer peripheral side surface and an outdoor side surface is formed on the outdoor side of the inner peripheral side (lower side) end of the upper frame 11, similarly to the vertical frame 13. In the closed state of the external obstacle 2a, the upper end (upper collar 21a) of the external obstacle 2a is stored. Further, an extended piece 12 a extending outward is formed on the outdoor side of the inner peripheral side (upper) end of the lower frame 12.

さらに、図３に示すように、下枠１２の内周側（上側）端部の室内側（アルミ部材部分）には、上向きに延びる立設片１７を形成してあり、立設片１７の上端には、タイト材ホルダ１５を形成してある。タイト材ホルダ１５は、上向きに開口する溝状のもので、タイト材１６を嵌め込んで取り付けてある。タイト材１６は、不燃性のものであって、内障子２ｂの閉鎖状態において、内障子２ｂの下端（下框２２ｂ）の室内側部分に当接して、気密性・水密性を確保するものである。 Further, as shown in FIG. 3, a standing piece 17 extending upward is formed on the indoor side (aluminum member portion) of the inner peripheral side (upper side) end of the lower frame 12. A tight material holder 15 is formed at the upper end. The tight material holder 15 has a groove shape that opens upward, and is fitted with a tight material 16. The tight material 16 is nonflammable, and in contact with the indoor side portion of the lower end (lower arm 22b) of the inner impingement 2b in a closed state of the inner impingement 2b, to ensure airtightness and water tightness. is there.

そして、図１及び図３に示すように、内障子２ｂの下框２２ｂは、エッジ材３を有している。エッジ材３は、水平片３２と、水平片３２の室外側端から下向きに延びる垂下片３１からなる断面略Ｌ字形のもので、水平片３２を下框２２ｂの下面にネジ止めしてある。水平片３２の見込幅は下框２２ｂの見込幅より短く、下框２２ｂの室外側寄りに取り付けてあって、内障子２ｂの閉鎖状態においてタイト材１６とは干渉しない。そして垂下片３１は、下框２２ｂの室外側端に位置していて、下框２２ｂの室外側面から垂下片３１の見込厚さ分だけ室外側に突出しており、縦框２３ｂの室外側面と面一になっている。また、垂下片３１は、内障子２ｂの閉鎖状態において、下枠１２のタイト材ホルダ１５の室外側面に対向している。さらに、図１に示すように、エッジ材３の左右幅は、下框２２ｂの左右幅より長く、エッジ材３の左右端は、縦枠１３のガイド溝１４ｂに呑み込まれている。なお、縦框２３ｂの下端部には、外障子２ａと内障子２ｂを連動させるためのワイヤ３０を接続するための接続部材３０ａを取り付けてあるが、図４に示すように、接続部材３０ａは縦框２３ｂの室内側部分に係合しており、室外側に位置するエッジ材３とは干渉しない形状となっている。また、垂下片３１の室内側面には、室内側に向けて開口する溝状の発泡材ホルダ３３を形成してあって、加熱発泡材４を嵌め込んで取り付けてある。一方、下枠１２の立設片１７の室外側にも、室外側に向けて開口する溝状の発泡材ホルダ１８を形成してあって、加熱発泡材４を嵌め込んで取り付けてある。この加熱発泡材４は、加熱されることにより発泡して厚さ方向（取付面に対して垂直方向）に膨張するものであって、火災時に発泡して下枠１２と下框２２ｂとの隙間を塞ぐ。 And as shown in FIG.1 and FIG.3, the lower collar 22b of the inner impeller 2b has the edge material 3. As shown in FIG. The edge member 3 has a substantially L-shaped cross section including a horizontal piece 32 and a hanging piece 31 extending downward from the outdoor side end of the horizontal piece 32, and the horizontal piece 32 is screwed to the lower surface of the lower rod 22b. The expected width of the horizontal piece 32 is shorter than the expected width of the lower collar 22b, and is attached to the outside of the lower collar 22b, and does not interfere with the tight material 16 in the closed state of the inner shoji 2b. And the drooping piece 31 is located at the outdoor side end of the lower rod 22b, protrudes from the outdoor side surface of the lower rod 22b to the outdoor side by the expected thickness of the hanging piece 31, and the outdoor side surface and the surface of the vertical rod 23b. It is one. Moreover, the drooping piece 31 faces the outdoor side surface of the tight material holder 15 of the lower frame 12 in the closed state of the inner impeller 2b. Further, as shown in FIG. 1, the left and right width of the edge member 3 is longer than the left and right width of the lower rod 22 b, and the left and right ends of the edge member 3 are swept into the guide groove 14 b of the vertical frame 13. In addition, although the connection member 30a for connecting the wire 30 for interlocking the outer shoji 2a and the inner pouch 2b is attached to the lower end part of the vertical shaft 23b, as shown in FIG. It is engaged with the indoor side portion of the vertical rod 23b, and has a shape that does not interfere with the edge member 3 located on the outdoor side. Further, a groove-like foam material holder 33 that opens toward the indoor side is formed on the indoor side surface of the hanging piece 31, and the heating foam material 4 is fitted and attached thereto. On the other hand, a groove-like foam material holder 18 that opens toward the outdoor side is formed on the outdoor side of the standing piece 17 of the lower frame 12, and the heating foam material 4 is fitted and attached. The heated foam material 4 is foamed by being heated and expands in the thickness direction (perpendicular to the mounting surface). The heated foam material 4 is foamed in the event of a fire and has a gap between the lower frame 12 and the lower rod 22b. Block.

このように構成した上げ下げ窓によれば、内障子２ｂの下框２２ｂに取り付けたエッジ材３の左右端が縦枠１３のガイド溝１４ｂに呑み込まれているので、見込方向から見て縦枠１３とエッジ材３（下框２２ｂ）の間に隙間がなく、火災時において、エッジ材３の垂下片３１がタイト材１６を炎熱から保護する。また、内障子２ｂの下框２２ｂより左右に長いエッジ材３に加熱発泡材４を取り付けてあり、下枠１２の立設片１７に取り付けた加熱発泡材４と併せて、火災時に発泡して内障子２ｂ下端部の全長を覆い、下枠１２や下框２２ｂの熱伸びやガタツキにより生じた隙間を塞ぐ。これらにより、火災時に内障子２ｂの下端部において室内外が連通することを確実に防ぐ。 According to the raising / lowering window configured in this manner, the left and right ends of the edge member 3 attached to the lower collar 22b of the inner limb 2b are sandwiched in the guide grooves 14b of the vertical frame 13, so that the vertical frame 13 is viewed from the expected direction. There is no gap between the edge member 3 and the edge member 3 (lower rod 22b), and the drooping piece 31 of the edge member 3 protects the tight member 16 from flame heat in the event of a fire. Further, the heating foam 4 is attached to the edge material 3 that is longer to the left and right than the lower collar 22b of the inner impeller 2b, and foamed in the event of a fire in combination with the heating foam 4 attached to the standing piece 17 of the lower frame 12. Covers the entire length of the lower end portion of the inner impeller 2b, and closes the gap caused by thermal expansion and rattling of the lower frame 12 and the lower collar 22b. Thus, it is possible to reliably prevent the indoor and outdoor communication at the lower end portion of the inner impingement 2b during a fire.

なお、図５及び図６に示すように、上枠１１及び縦枠１３に形成した持出部１１ａ，１３ａには、カバー５を取り付けてある。カバー５は、見込面と見付面を有していて、持出部１１ａ，１３ａの外周側面と室外側面を覆うものであり、カバー５の見込面と持出部１１ａ，１３ａの外周側面及びカバー５の見付面と持出部１１ａ，１３ａの室外側面の間には、空間部５ａが形成されている。このカバー５により、持出部１１ａ，１３ａが直接炎にさらされることはなく、さらに、空間部５ａがあるので炎の熱が持出部１１ａ，１３ａに伝わりにくい。これらにより、火災時において持出部１１ａ，１３ａが溶け落ちることを防いでおり、外障子２ａが脱落して室内外が連通してしまうことがない。また、カバー５の室外側面には、網戸枠体６を取り付けてある。網戸枠体６は、上げ下げ窓の開放時において虫の侵入を防ぐものであり、カバー５の室外側面が網戸枠体６に覆われることで、より炎の熱が持出部１１ａ，１３ａに伝わりにくくなる。そして、網戸枠体６を持出部１１ａ，１３ａに直接取り付けると、網戸枠体６の荷重が持出部１１ａ，１３ａの先端に集中してかかるが、網戸枠体６をカバー５に取り付けると、網戸枠体６の荷重がカバー５を介して持出部１１ａ，１３ａの全体に分散し、持出部１１ａ，１３ａの変形が抑制される。 As shown in FIGS. 5 and 6, the cover 5 is attached to the take-out portions 11 a and 13 a formed in the upper frame 11 and the vertical frame 13. The cover 5 has a prospective surface and a finding surface, and covers the outer peripheral side surface and the outdoor side surface of the take-out portions 11a and 13a, and the cover surface 5 and the outer peripheral side surface of the take-out portions 11a and 13a and A space portion 5a is formed between the finding surface of the cover 5 and the outdoor side surfaces of the take-out portions 11a and 13a. By this cover 5, the take-out portions 11a and 13a are not directly exposed to the flame, and furthermore, since there is the space portion 5a, the heat of the flame is not easily transmitted to the take-out portions 11a and 13a. Thus, the carry-out portions 11a and 13a are prevented from melting in the event of a fire, and the external shoji 2a is not dropped and the interior and the exterior are not communicated. A screen door frame 6 is attached to the outdoor side surface of the cover 5. The screen door frame body 6 prevents insects from entering when the raising and lowering windows are opened, and the outdoor side surface of the cover 5 is covered with the screen door frame body 6, so that the heat of the flame is transmitted to the take-out portions 11a and 13a. It becomes difficult. When the screen door frame 6 is directly attached to the take-out portions 11 a and 13 a, the load of the screen door frame 6 is concentrated on the tips of the take-out portions 11 a and 13 a, but when the screen door frame 6 is attached to the cover 5. The load of the screen door frame 6 is dispersed throughout the take-out portions 11a and 13a through the cover 5, and deformation of the take-out portions 11a and 13a is suppressed.

また、外障子２ａ及び内障子２ｂのガラスパネル２４ａ，２４ｂの全周にわたって、鉄製で断面コ字形のパネル支持材７を取り付けてある。これは、サッシが炎熱にさらされて上框２１ａ，２１ｂ、下框２２ａ，２２ｂ及び縦框２３ａ，２３ｂが融解した場合にガラスパネル２４ａ，２４ｂが外れるのを防ぎ、上げ下げ窓の気密性を維持するためのものである。 Moreover, the panel support material 7 made of iron and having a U-shaped cross-section is attached to the entire circumference of the glass panels 24a and 24b of the external shoji 2a and the internal shoji 2b. This prevents the glass panels 24a and 24b from coming off when the sash is exposed to flame heat and the upper ridges 21a and 21b, the lower ridges 22a and 22b and the vertical ridges 23a and 23b are melted, and maintains the airtightness of the raised and lowered windows. Is to do.

さらに、外障子２ａ及び内障子２ｂの、各框（上框２１ａ，２１ｂ、下框２２ａ，２２ｂ及び縦框２３ａ，２３ｂ）の中空部内には、鉄製で断面コ字形の補強材８を挿入してある（外障子２ａの上框２１ａの補強材８のみ、断面Ｌ字形である）。補強材８は各框の全長にわたるもので、外側からネジ止めしてある。これは、サッシが炎熱にさらされた際に、各框の伸びを抑えるためのものである。なお、エッジ材３は内障子２ｂの下框２２ｂの補強材８にネジ止めされており、火災時に下框２２ｂが変形・融解してもエッジ材３が脱落しない。 Furthermore, the reinforcing material 8 made of iron and having a U-shaped cross section is inserted into the hollow portion of each of the collars (upper collars 21a, 21b, lower collars 22a, 22b and longitudinal collars 23a, 23b) of the external shoji 2a and the inner shoji 2b. (Only the reinforcing member 8 of the upper collar 21a of the outer shoji 2a has an L-shaped cross section). The reinforcing member 8 extends over the entire length of each ridge and is screwed from the outside. This is to suppress the elongation of each heel when the sash is exposed to flame heat. Note that the edge member 3 is screwed to the reinforcing member 8 of the lower collar 22b of the inner impeller 2b, and the edge member 3 does not fall off even if the lower collar 22b is deformed or melted in a fire.
