Description
本発明は、建築物における、窓や扉などの建具により開閉自在に塞がれる開口部に設置される枠(サッシ)、建具、及び、枠又は建具への防火材の取付方法に関する。 BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a frame (sash) installed at an opening that is openably closed by a fitting such as a window or a door in a building, a fitting, and a method of attaching a fireproof material to the frame or fitting.
防火地域又は準防火地域において、例えば窓や扉などの建具で塞がれる建築物の開口部は、隣家の火災から自家への延焼を防いだり、自家の火災から隣家への延焼を防いだりするため、防火構造が施されている。具体的には、建具と、建具を建築物の壁(外壁や間仕切り壁など)に取り付けるための矩形状の枠(サッシ)との間隙から炎が通過することがないように、枠の防火性が高められている。例えば、枠の建具と対向する面に、加熱により膨張する熱膨張性耐火材が防火材として取り付けられており、この防火材が、火災時の熱により膨張して上述した間隙を塞ぐことで、防火性が発現されている。 In the fire zone or near fire zone, for example, the opening of a building blocked by fittings such as windows and doors prevents the spread of fire to the house from the fire of the next house or prevents the spread of the fire to the next house from the fire of the house. Therefore, fire protection structure is provided. Specifically, the fire resistance of the frame so that the flame does not pass through the gap between the fixture and the rectangular frame (sash) for attaching the fixture to the wall of the building (such as the outer wall or the partition wall) Is elevated. For example, a thermally expandable refractory material that expands due to heating is attached as a fire protection material to the surface of the frame that faces the fittings, and the fire protection material expands due to heat during a fire to close the above-mentioned gap. Fire resistance has been expressed.
従来においては、例えば特許文献1に記載されているような、表裏面が平坦で長尺な長尺板状の防火材が、例えば粘着テープなどを介して枠の全周にわたって取り付けられている。 Conventionally, a long plate-shaped fire protection material having flat front and back surfaces and having a long plate shape as described in, for example, Patent Document 1 is attached over the entire circumference of the frame via, for example, an adhesive tape.
しかし、枠は、コーナー部分については直角に折れ曲がっていることから、上述した長尺板状の防火材が取り付けられている場合には、枠のコーナー部分では、2つの防火材が組み合わされて取り付けられていて、防火材同士の間に隙間が生じやすい。また、枠の種類によっては形状が複雑なものもあり、この場合に、複数の長尺板状の防火材を枠の形状に合わせて組み合せて取り付けると、同様に、防火材同士の間に隙間が生じやすい。防火材同士の間に隙間が生じると、防火性に影響を与える一方で、複数の防火材を隙間なく取り付けるのは作業が大変手間である。 However, since the frame is bent at a right angle in the corner portion, when the long plate-like fire protection material described above is attached, the two fire protection materials are combined and attached in the corner portion of the frame It is easy to create a gap between fire protection materials. In addition, depending on the type of frame, the shape may be complicated, and in this case, when a plurality of long plate-shaped fire protection materials are combined and attached according to the shape of the frame, similarly, gaps between the fire protection materials Is likely to occur. While gaps between fire protection materials affect fire resistance, it is very laborious to attach a plurality of fire protection materials without gaps.

The corner portion C1 of the fire protection material 1 being disposed at the corner portion C2 of the mounting frame portion 11A means that the pointed portion A1 of the end of the corner portion C1 of the fire protection material 1 is the corner portion of the corner portion C2 of the mounting frame portion 11A. Besides being disposed so as to abut A2, it also includes the case where the pointed portion A1 at the end of the corner C1 of the fire protection material 1 is disposed without abutted on the corner A2 of the corner portion C2 of the mounting frame 11A. In order to attach this kind of fire protection material over the entire circumference of the attachment frame portion 11A of the frame 11, the lengths D1 and D2 are set to appropriate lengths, and as shown in FIG. 2, four first embodiments The fire protection material 1 may be attached so that no gap is generated between the fire protection material 1 adjacent to the corner portions C2 at the four corners of the mounting frame 11A, or as shown in FIG. Between the fire protection materials 1 of the first embodiment attached, the conventional flat-plate shaped fire protection material 16 with flat front and back surfaces butts the end faces of the fire protection material 1 and the fire protection material 16 with each other And there may be no gap between them. The fire protection material 1 is attached to the frame 11 via an adhesive tape (not shown) or the like. The pressure-sensitive adhesive tape can be attached to the thermal expansion material 2 in advance, and in that case, it is preferable that a release paper (not shown) is further attached to the pressure-sensitive adhesive tape.
図6に示されるように火災が発生すると、防火材1(熱膨張材2)が火の熱により膨張することで、窓10と枠11との間隙Sを塞ぐ。これにより、窓10と枠11との間から火や煙が侵入・侵出することを低減又は防止することができる。 As shown in FIG. 6, when a fire occurs, the fire protection material 1 (thermal expansion material 2) expands due to the heat of the fire, thereby closing the gap S between the window 10 and the frame 11. In this way, it is possible to reduce or prevent the intrusion of fire or smoke from between the window 10 and the frame 11.
このように、第1実施形態の防火材付き枠11によると、熱膨張材2が、第1の部分3と、第1の部分3から折れ曲がる第2の部分4とを備えていて、枠11(取付枠部11A)のコーナー部分C2の形状に沿った形状を有しているので、継ぎ目なく取り付けることが難しい枠11(取付枠部11A)のコーナー部分C2に対して、継ぎ目が生じることなく防火材1を取り付けることができる。よって、よって、枠11を防火性に優れたものとすることができる。加えて、防火材1を枠11に容易に取り付けることができるので、取り付けの際には、取付作業を大いに効率化することができる。 Thus, according to the fireproof material-attached frame 11 of the first embodiment, the thermal expansion material 2 is provided with the first portion 3 and the second portion 4 bent from the first portion 3. Since it has a shape along the shape of the corner portion C2 of the (attachment frame portion 11A), a joint does not occur with respect to the corner portion C2 of the frame 11 (attachment frame portion 11A) which is difficult to attach seamlessly. Fire protection material 1 can be attached. Therefore, the frame 11 can be made excellent in fire resistance. In addition, since the fire protection material 1 can be easily attached to the frame 11, the attachment work can be made highly efficient at the time of attachment.

次に、図9及び図10は、本発明の第2実施形態に係る防火材付き枠21(以下、単に「枠」という。)の外観構成を示している。第2実施形態の枠21は、引違い窓20用のものであり、建築物の壁(図示せず)などの構造材の開口部22に従来から公知の方法によって固定される。なお、図10では、窓20及び枠21を模式的に示し、窓20や枠21の詳細な構造の図示は省略している。 Next, FIG. 9 and FIG. 10 show the appearance configuration of a frame 21 with a fire protection material (hereinafter simply referred to as a “frame”) according to a second embodiment of the present invention. The frame 21 of the second embodiment is for the sliding window 20 and is fixed to the opening 22 of a structural material such as a building wall (not shown) by a conventionally known method. In FIG. 10, the window 20 and the frame 21 are schematically shown, and the detailed structures of the window 20 and the frame 21 are not shown.
枠21は、正面視矩形状であり、上下左右の4つの細長い側縁部21a〜21dを枠状に組み合わせて構成されている。また、枠21(各側縁部21a〜21d)は、断面視コ字形状であり、枠21の内周面に長手方向に沿って凹溝26が形成されている。よって、枠21(各側縁部21a〜21d)は、凹溝26を構成する基板部21Aと、基板部21Aの両側縁より立ち上がる一対の側板部21Bとを備えている。各側縁部21a〜21dの基板部21Aは、表面同士が90度の角度をなす(直交する)ように周状に連なっている。また、各側縁部21a〜21dの側板部21Bは、表面同士が同一平面となるように周状に連なっている。枠21の材質は特に限定されるものではなく、例えばアルミニウム製、合成樹脂製、アルミニウム及び合成樹脂の複合製、木質製、及び鋼製などであってよい。 The frame 21 has a rectangular shape in a front view, and is configured by combining four elongated side edges 21 a to 21 d in upper, lower, left, and right in a frame shape. Further, the frame 21 (each side edge 21a to 21d) is U-shaped in cross section, and a recessed groove 26 is formed on the inner peripheral surface of the frame 21 along the longitudinal direction. Therefore, the frame 21 (the side edges 21a to 21d) includes the substrate 21A constituting the recessed groove 26 and a pair of side plates 21B which rise from both side edges of the substrate 21A. The substrate portions 21A of the side edge portions 21a to 21d are circumferentially connected such that the surfaces form an angle of 90 degrees (orthogonal). Further, the side plate portions 21B of the side edge portions 21a to 21d are connected in a circumferential shape so that the surfaces are flush with each other. The material of the frame 21 is not particularly limited, and may be, for example, aluminum, synthetic resin, composite of aluminum and synthetic resin, wood, steel, or the like.
2つの窓20は、パネル23の周囲に框24が固定されたものであり、框24は、上下左右の細長い縁框部24A〜24Dを枠状に組み合せて構成されている。框24は、アルミニウムを初めとする金属製、木製、合成樹脂製など、任意の材料から形成されていてよい。パネル23は、ガラス製や合成樹脂製など、任意の材料から形成されていてよい。2つの窓20は、閉窓時に框24の上縁框部24A、下縁框部24B、さらに左縁框部24Cないしは右縁框部24Dが枠21の基板部21Aと対向しており、鍵25を下方向に回動させて各框24を左右方向にスライドさせることで、開窓する。 The two windows 20 are formed by fixing a weir 24 around the panel 23. The weir 24 is configured by combining vertically and horizontally elongated rims 24A to 24D in a frame shape. The crucible 24 may be made of any material such as metal such as aluminum, wood, synthetic resin and the like. The panel 23 may be made of any material such as glass or synthetic resin. When the two windows 20 are closed, the upper rim portion 24A, the lower rim portion 24B, the left rim portion 24C or the right rim portion 24D of the crucible 24 face the substrate portion 21A of the frame 21 when the window is closed. The windows 25 are opened by rotating the rods 25 downward and sliding the wedges 24 in the lateral direction.
防火材1は、図11に示すように、耐火性及び熱膨張性を有する熱膨張材2を少なくとも備えている。熱膨張材2は、板状の第1の部分3と、第1の部分3と一体的に形成されかつ第1の部分3から折れ曲がる板状の第2の部分4とを少なくとも備えており、この第1の部分3と第2の部分4とが、表面同士及び裏面同士が角度をなすように連なっている、つまりは、一方の部分3の一つの側縁に他方の部分4が起立するように連なっている。また、第1の部分3と第2の部分4とは直交するようにして連なっており、側面視L字型となっている。なお、表面及び裏面とは、偏平状の板材において、最も面積の大きい面のことを指す。 The fire protection material 1 at least includes a thermal expansion material 2 having fire resistance and thermal expansion, as shown in FIG. The thermal expansion material 2 includes at least a plate-like first portion 3 and a plate-like second portion 4 integrally formed with the first portion 3 and bent from the first portion 3; The first portion 3 and the second portion 4 are connected such that the front surfaces and the back surfaces form an angle, that is, the other portion 4 stands on one side edge of one portion 3 It is in line. Further, the first portion 3 and the second portion 4 are arranged to be orthogonal to each other, and are L-shaped in side view. The front and back surfaces refer to the surface of the flat plate material having the largest area.
熱膨張材2の素材は、第1実施形態と同様であり、ここでは詳細な説明は省略する。熱膨張材2の寸法、すなわち長さL、幅(第1の部分の長さD1、第2の部分の長さD2)、厚み(第1の部分の厚さT1、第2の部分の厚さT2)は、特に限定されず、枠21の寸法に応じて適宜設定される。 The raw material of the thermal expansion material 2 is the same as that of 1st Embodiment, and detailed description is abbreviate | omitted here. Dimensions of the thermal expansion material 2, that is, length L, width (length D1 of the first portion, length D2 of the second portion), thickness (thickness T1 of the first portion, thickness of the second portion The dimension T2) is not particularly limited, and is appropriately set in accordance with the dimensions of the frame 21.
熱膨張材2は、射出成形により上述した形状に成形することが好ましいが、押出成形や圧縮成形などで成形してもよい。射出成形により成形すると、熱膨張材2を無駄なく歩留まりよく製造できるうえ、複雑な形状に成形できるので好ましい。また、柱状の熱膨張材を作製し、この柱状の熱膨張材から側面視L字型の熱膨張材2を切り取ることで成形してもよい。 The thermal expansion material 2 is preferably formed into the above-described shape by injection molding, but may be formed by extrusion molding, compression molding, or the like. Molding by injection molding is preferable because the thermal expansion material 2 can be produced with high yield without waste and can be molded into a complicated shape. Alternatively, a columnar thermal expansion material may be produced, and the thermal expansion material 2 in an L-shape in side view may be cut out of the columnar thermal expansion material.
防火材1を枠21に取り付けるに当たっては、枠21の框24と対向する内周面、すなわち、框24の縁框部24A〜24Dの端面と重なって延びる枠21の基板部21Aの表面に、防火材1が取り付けられる。このとき、防火材1の第1の部分3が基板部21Aに第2の部分4が一方の側板部21Bにそれぞれ当たるように、防火材1が取り付けられる。言い換えれば、防火材1の角部(第1の部分3と第2の部分4の折曲部)C1が、枠21の基板部21Aと一方の側板部21Bとのコーナー部分C3に突き当たるように防火材1が取り付けられる。なお、枠21の基板部21Aの全周にわたって防火材1を取り付けるためには、長さLを適当な長さに設定し、例えば4つの防火材1を枠21の上下左右の側縁部21a〜21dに沿って隣り合う防火材1との間に隙間が生じないよう取り付ける。防火材1は、枠21に粘着テープ(図示せず)などを介して取り付けられる。なお、粘着テープは、熱膨張材2に事前に貼り付けておくことができ、その場合、粘着テープにはさらに剥離紙(図示せず)が貼り付けられているのが好ましい。 When attaching the fire protection material 1 to the frame 21, the inner peripheral surface of the frame 21 facing the ridge 24, that is, the surface of the base 21 A of the frame 21 extending overlapping the end face of the rim portions 24A to 24D of the ridge 24 The fire protection material 1 is attached. At this time, the fire protection material 1 is attached such that the first portion 3 of the fire protection material 1 abuts on the substrate portion 21A and the second portion 4 abuts on the side plate portion 21B. In other words, the corner portion C1 of the fire protection material 1 (the bent portion of the first portion 3 and the second portion 4) abuts on the corner portion C3 of the substrate portion 21A of the frame 21 and one side plate portion 21B. The fire protection material 1 is attached. In addition, in order to attach the fire protection material 1 over the perimeter of the board part 21A of the frame 21, the length L is set to an appropriate length, for example, four fire protection materials 1 are the side edges 21a of the top, bottom, left and right of the frame 21. It attaches so that a clearance gap may not arise between the fire prevention materials 1 which adjoin along -21d. The fire protection material 1 is attached to the frame 21 via an adhesive tape (not shown) or the like. The pressure-sensitive adhesive tape can be attached to the thermal expansion material 2 in advance, and in that case, it is preferable that a release paper (not shown) is further attached to the pressure-sensitive adhesive tape.
図12に示されるように火災が発生すると、防火材1(熱膨張材2)が火の熱により膨張することで、窓20と枠21との間隙Sを塞ぐ。これにより、窓20と枠21との間から火や煙が侵入・侵出することを低減又は防止することができる。 As shown in FIG. 12, when a fire occurs, the fire protection material 1 (thermal expansion material 2) expands due to the heat of the fire, thereby closing the gap S between the window 20 and the frame 21. In this way, it is possible to reduce or prevent the intrusion of fire or smoke from between the window 20 and the frame 21.
なお、枠21は、基板部21Aと側板部21Bとのコーナー部分C3だけでなく、一対の側板部21Bの間にその他の板状部が基板部21Aから起立している場合には、防火材1の寸法を適宜調整することで、基板部21Aと上記板状部とのコーナー部分に防火材1の角部C1が突き当たるように、つまりは、防火材1の第1の部分3が基板部21Aに第2の部分4が前記板状部にそれぞれ当たるように、防火材1を取り付けることができる。 The frame 21 is not only the corner portion C3 of the substrate portion 21A and the side plate portion 21B, but also the fireproof material when the other plate-like portion is erected from the substrate portion 21A between the pair of side plate portions 21B. By appropriately adjusting the dimension of 1, the corner portion C1 of the fire protection material 1 abuts on the corner portion between the substrate portion 21A and the plate-like portion, that is, the first portion 3 of the fire protection material 1 is a substrate portion The fire protection material 1 can be attached such that the second portions 4 respectively hit the plate-like portion 21A.
このように、第2実施形態の防火材付き枠21によると、枠21の基板部21Aから例えば側板部21Bやその他の板状部が突き出ていて、枠21の形状が複雑になっていても、熱膨張材2が、第1の部分3と、第1の部分3から折れ曲がる第2の部分4とを備えており、枠21の形状に沿った形状を有しているので、枠21の当該複雑な形状となる部分に対しても継ぎ目が生じることなく防火材1を取り付けることができる。よって、枠21を防火性に優れたものとすることができる。加えて、防火材1を枠21に容易に取り付けることができるので、取り付けの際には、取付作業を大いに効率化することができる。 As described above, according to the fireproof material-attached frame 21 of the second embodiment, for example, the side plate 21B and other plate-like parts project from the substrate 21A of the frame 21 and the shape of the frame 21 is complicated. Since the thermal expansion material 2 includes the first portion 3 and the second portion 4 bent from the first portion 3 and has a shape conforming to the shape of the frame 21, The fire protection material 1 can be attached to the part having the complicated shape without any seam. Therefore, the frame 21 can be made excellent in fire resistance. In addition, since the fire protection material 1 can be easily attached to the frame 21, the attachment work can be made highly efficient at the time of attachment.
以上、本発明の第2実施形態について説明したが、第2実施形態は上記内容のものに限定されるものではなく、その趣旨を逸脱しない限りにおいて、種々の変更が可能である。例えば、熱膨張材2の第1の部分3及び第2の部分4は直交しているが、折れ曲がっていれば直交していなくてもよい。また、熱膨張材2の第1の部分3及び第2の部分4はともに平板状であるが、枠21の形状に応じて例えば第2の部分4を曲板状などにしてもよい。 As mentioned above, although 2nd Embodiment of this invention was described, 2nd Embodiment is not limited to the thing of the said content, A various change is possible unless it deviates from the meaning. For example, although the first portion 3 and the second portion 4 of the thermal expansion material 2 are orthogonal, they may not be orthogonal as long as they are bent. Moreover, although both the 1st part 3 and the 2nd part 4 of the thermal expansion material 2 are flat form, according to the shape of the frame 21, for example, the 2nd part 4 may be made into a curved plate shape etc.
また、熱膨張材2は、外形がL字型のものには限定されず、図13に示すようなコ字型のものであってもよい。図13では、熱膨張材2は、第1の部分3と一体的に形成されかつ第1の部分3から折れ曲がる板状の第3の部分5をさらに備えており、2つの部分4,5が、第1の部分3に対して、第1の部分の対向する一対の側縁から表面同士が角度をなすように起立している。つまり、熱膨張材2は、板状の3つの部分3〜5が一体的に形成され、かつ、隣接する2つの部分同士が直角をなすよう形成されている。この場合、防火材1は、第1の部分3が枠21の基板部21Aに当たるとともに、第2の部分4及び第3の部分5が枠21の各側板部21Bに当たるように、枠21に取り付けることができる。 Further, the thermal expansion material 2 is not limited to the L-shaped external shape, and may be a U-shaped as shown in FIG. In FIG. 13, the thermal expansion material 2 further includes a plate-like third portion 5 integrally formed with the first portion 3 and bent from the first portion 3, and the two portions 4 and 5 are With respect to the first portion 3, the surfaces are erected at an angle from a pair of opposing side edges of the first portion. That is, the thermal expansion material 2 is formed such that the three plate-like portions 3 to 5 are integrally formed, and two adjacent portions form a right angle. In this case, the fire protection material 1 is attached to the frame 21 such that the first portion 3 contacts the substrate portion 21A of the frame 21 and the second portion 4 and the third portion 5 contact each side plate portion 21B of the frame 21. be able to.
また、熱膨張材2は、図13のコ字型の熱膨張材2について、第2の部分4及び第3の部分5の先端部Eを、それぞれ外側に折れ曲げた形状としてもよい。この場合、図14に示すように、外側に曲がった先端部Eを、枠21の側板部21Bの端面に当たるように、防火材1を枠21に取り付けることで、防火性を向上できる。 In addition, the thermal expansion material 2 may have a shape in which the front end portions E of the second portion 4 and the third portion 5 of the U-shaped thermal expansion material 2 in FIG. 13 are bent outward. In this case, as shown in FIG. 14, the fire resistance can be improved by attaching the fire protection material 1 to the frame 21 such that the tip E bent outwards contacts the end face of the side plate 21 B of the frame 21.
また、第2実施形態の防火材付き枠21も、防火材1を、熱膨張材2と、熱膨張材2の少なくとも一部を被覆する化粧材(図示せず)とを備えた構成のものとすることができる。また、防火材1を枠21に取り付けるための手段は、粘着テープに限られず、接着剤、ねじなどの物理固定を用いてもよい。 In addition, the fireproof material-attached frame 21 of the second embodiment also includes the fireproof material 1, the thermal expansion material 2, and a decorative material (not shown) covering at least a part of the thermal expansion material 2 It can be done. Further, the means for attaching the fire protection material 1 to the frame 21 is not limited to the adhesive tape, and physical fixing such as an adhesive or a screw may be used.
