また、上記構成の防火構造において、耐火材によって、前記第１の間仕切り材の貫通孔内及び前記第２の間仕切り材の貫通孔内が閉塞されていることが好ましい。 Further, in the fireproof structure having the above structure, it is preferable that the inside of the through hole of the first partition member and the inside of the through hole of the second partition member are closed by a refractory material.
本発明の建築物の区画体における貫通部の防火構造によれば、施工作業が簡易な防火構造となる。 According to the fireproof structure of the penetrating portion of the building partition of the present invention, the fireproof structure is simple in construction work.
以下、本発明の実施形態について添付図面を参照して説明する。本発明の防火構造は、複層建築物の壁、床、天井などの区画体に施工され、区画体に形成された貫通部から火災時に炎や熱が漏洩することを防止するためのものである。 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The fireproof structure of the present invention is applied to a partition such as a wall, floor, or ceiling of a multi-story building, and is for preventing flame or heat from leaking from a penetrating part formed in the partition during a fire. is there.
図１は、本発明の一実施形態に係る防火構造を示しており、区画体に設けられた貫通部に配管やケーブルなどの管体が挿通された状態を説明するための模式部分断面図である。なお、図１(ａ)で図示した例は、貫通部に熱膨張性耐火シートを用いた例であり、図１(ｂ)で図示した例は、熱膨張性耐火シートを用いない例である。なお、図１の実施形態は、コンセントボックス４とケーブル電線管３を配置した例である。
区画体は、第１と第２の間仕切り材（壁５）を備えている。上記間仕切り材としては、ＡＬＣ板、プレキャストコンクリート板などの耐火性の高い素材を用いることができる。また、上記間仕切り材として、強化石膏ボード、ケイ酸カルシウム板、石膏ボード又はケイ酸カルシウム板にセラミックブランケットやロックウールフェルトを積層させた積層板などを用いることができる。なお、壁５の周囲には、図示は省略しているが、複数の根太、梁、野縁、野縁受けなどが配置されている。
FIG. 1 shows a fire protection structure according to an embodiment of the present invention, and is a schematic partial cross-sectional view for explaining a state in which a pipe body such as a pipe or a cable is inserted into a penetrating portion provided in a partition body. is there. The example shown in FIG. 1(a) is an example using a heat-expandable fire resistant sheet in the penetrating portion, and the example shown in FIG. 1(b) is an example not using the heat-expandable fire resistant sheet. .. The embodiment of FIG. 1 is an example in which the outlet box 4 and the cable conduit 3 are arranged.
The partition body includes first and second partition members (wall 5). As the partition material, a material having high fire resistance such as an ALC plate or a precast concrete plate can be used. As the partitioning material, a reinforced gypsum board, a calcium silicate board, a gypsum board or a calcium silicate board laminated with a ceramic blanket or rock wool felt can be used. Although not shown in the drawing, a plurality of joists, beams, field edges, field edge supports, etc. are arranged around the wall 5.
区画体は、複数の壁材５で囲まれる中空空間を有する中空構造となっている。複数の壁材５には、管体（ケーブル電線管３）を挿通するための貫通孔がそれぞれの壁５に形成されており、両貫通孔及び中空空間により、貫通部が構成されている。 The partition body has a hollow structure having a hollow space surrounded by a plurality of wall materials 5. Through-holes for inserting the tubular body (the cable conduit 3) are formed in each of the wall members 5, and the through-holes are formed by the both through-holes and the hollow space.
貫通部に挿通される管体としては、例えば、冷媒管、熱媒管、水道管、下水管、注排水管、ガス管、暖冷房用媒体移送管、通気管、電線ケーブル、光ファイバーケーブルなどが挙げられる。 Examples of the pipe inserted into the penetrating part include a refrigerant pipe, a heat medium pipe, a water pipe, a sewer pipe, a water discharge pipe, a gas pipe, a heating/cooling medium transfer pipe, a ventilation pipe, an electric wire cable, and an optical fiber cable. Can be mentioned.
図１(ａ)で図示した例では、壁５上に突き出るケーブル電線管５の外周面に熱膨張性耐火シート（シート１）が設けられており、ケーブル電線管５の壁５から室内空間側に露出した根元までの貫通孔内に、耐火材（パテ２）が設けられている。 In the example shown in FIG. 1( a ), a thermally expansive fire-resistant sheet (sheet 1) is provided on the outer peripheral surface of the cable conduit 5 protruding above the wall 5, and the wall 5 of the cable conduit 5 has an interior space side. A refractory material (putty 2) is provided in the through hole that is exposed to the root.
熱膨張性耐火シートは、本実施形態では所定の厚み（例えば０．１ｍｍ〜７．０ｍｍ）を有するシート状あるいは板状にした熱膨張性黒鉛を含有する樹脂シートであり、熱膨張性耐火シートに孔をあけて管体を貫通させ、樹脂シート自体の粘着力かあるいは粘着テープを予め熱膨張性耐火シートに貼り付けることにより、管体の外周面を被覆しつつ、壁５の管体の外周面に固定することができる。この熱膨張性耐火シートによる被覆は、貫通孔が熱膨張性耐火シートによって隠されていなくてもよいが、貫通孔が熱膨張性耐火シートによって隠されていることが好ましい。 In the present embodiment, the heat-expandable fire-resistant sheet is a resin sheet containing a sheet-like or plate-like heat-expandable graphite having a predetermined thickness (for example, 0.1 mm to 7.0 mm). By perforating the pipe body by making a hole in it, and by adhering the adhesive force of the resin sheet itself or the adhesive tape to the heat-expandable fireproof sheet in advance, while covering the outer peripheral surface of the pipe body, It can be fixed to the outer peripheral surface. In the coating with the heat-expandable fire resistant sheet, the through holes may not be hidden by the heat expandable fire resistant sheet, but it is preferable that the through holes are hidden by the heat expandable fire resistant sheet.
なお、壁５の貫通孔と管体との間の隙間に充填される耐火材は、シーリング剤（コーキング剤）、耐火パテ、セメントモルタルなどの不燃材、石膏ボード用目地処理材などを挙げることができる。なお、耐火材は、一方の壁５の貫通孔と管体との間の隙間に加えて、他方の壁５の貫通孔と管体との間の隙間にも充填されていることが好ましいが、いずれか一方の壁５の貫通孔と管体との間の隙間にだけ充填されていてもよい。 Examples of the refractory material filled in the gap between the through hole of the wall 5 and the pipe body include a sealing agent (caulking agent), a fire resistant putty, a non-combustible material such as cement mortar, and a joint treatment material for gypsum board. You can Note that it is preferable that the refractory material is filled not only in the gap between the through hole of the one wall 5 and the pipe body but also in the gap between the through hole of the other wall 5 and the pipe body. The gap may be filled only in the gap between the through hole of any one of the walls 5 and the tubular body.
なお、図示例では、壁５の貫通孔と管体との間の隙間を隠すために、パテ２を貫通孔に充填して上記隙間を埋めているが、必ずしもパテ２を貫通孔に充填する必要はなく、貫通孔入口付近の管体の周囲や貫通孔出口付近の管体の周囲に設けることで、貫通孔と管体との間の上記隙間を隠すようにしてもよい。 In the illustrated example, in order to hide the gap between the through hole of the wall 5 and the tubular body, the putty 2 is filled in the through hole to fill the above gap, but the putty 2 is not necessarily filled in the through hole. It is not necessary to provide the above-mentioned gap between the through hole and the tubular body by providing it around the tubular body near the inlet of the through hole or around the tubular body near the outlet of the through hole.
上述した耐火材を用いた区画体の防火構造では、壁５の貫通孔が耐火材によって被覆されているので、例えば壁５の外側の室内空間で火災が発生して、管体が溶融・焼失したとしても、耐火材が火災時の熱によってその厚さ方向である管体の径方向に熱膨張等により火炎を防ぎ、管体の溶融・焼失によりできる空間が閉塞される。また、熱膨張した耐火材によって、貫通孔が遮蔽されるうえ、貫通孔と管体との間の隙間は耐火材により埋められている。よって、区画体の貫通孔及び管体を完全に閉塞できるため、火炎や熱が貫通孔や管体から他方の壁５の外側にある室内空間に侵入して、延焼することを防ぐことができる。 In the fire protection structure of the partition body using the above-mentioned refractory material, since the through hole of the wall 5 is covered with the refractory material, for example, a fire occurs in the indoor space outside the wall 5, and the pipe body is melted and burned. Even if it does, the heat of the fireproof material prevents flames due to thermal expansion in the radial direction of the tubular body, which is the thickness direction thereof, and the space formed by melting and burning of the tubular body is closed. Further, the through-hole is shielded by the thermally expanded refractory material, and the gap between the through-hole and the tubular body is filled with the refractory material. Therefore, since the through hole and the pipe of the partition can be completely closed, it is possible to prevent the flame and heat from penetrating from the through hole and the pipe into the indoor space outside the other wall 5 to spread the fire. ..
また、耐火パテにより、壁５の貫通孔と管体との間の隙間が隠されるので、上記隙間を通して双方の室内空間を見えないようにすることができる。 Further, since the gap between the through hole of the wall 5 and the pipe body is hidden by the fireproof putty, it is possible to hide both indoor spaces through the gap.
さらに、耐火材は、室内空間側から管体が貫通している貫通孔に充填するだけでよく容易に設置できるうえに、複雑な管体形状であったり、複数の管体が貫通部に挿通されていたとしても、管体の形状などに合わせて耐火材を設けることができるので、従来の鋼製スリーブを用いる場合と比べて、簡易な施工作業で良好な防火性能を発現できる。加えて、鋼製スリーブを用いないので、切断加工した後の不要な鋼管の残り屑を廃棄する必要がなく、施工コストも低減できる。なお、本発明では複数の管体が貫通部に挿通されているので、複数の管体をまとめて耐火材で被覆することができ、複数の管体をそれぞれ個別に耐火材で被覆する場合に比べて効率よく施工できる。 Furthermore, the refractory material can be installed easily by filling the through holes through which the pipes penetrate from the indoor space side, and it has a complicated pipe shape or multiple pipes can be inserted into the penetration part. Even if it is done, since the refractory material can be provided according to the shape of the pipe body, as compared with the case where the conventional steel sleeve is used, good fireproof performance can be expressed by a simple construction work. In addition, since the steel sleeve is not used, it is not necessary to discard unnecessary steel pipe scraps after cutting, and the construction cost can be reduced. In the present invention, since the plurality of pipes are inserted through the through portion, it is possible to collectively cover the plurality of pipes with the refractory material, and when the plurality of pipe bodies are individually covered with the refractory material. Can be constructed more efficiently.
以上、本発明の一実施形態について説明したが、本発明は上記実施形態に限定されるものではなく、本発明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。 Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
例えば、上記実施形態の防火構造において、壁５上の貫通孔と管体との隙間に耐火材を設けているが、上記構成の防火構造において、前記第１の第１の間仕切り材上に突き出る前記管体の外周面及び前記第２の間仕切り材上に突き出る前記管体の外周面のいずれかに、熱膨張性耐火シートが設けてもよい。これにより、より良好な防火性能を発現できるが、図１(a)には、２つの壁５から突き出るそれぞれの管体の外周面のいずれか一方に対して熱膨張性耐火シートを設けられているが、２つの壁５から突き出るそれぞれの管体の外周面のいずれに対しても熱膨張性耐火シートを設けていてもよい。これにより、より確実な防火性能を発現することができる。 For example, in the fireproof structure of the above-described embodiment, the refractory material is provided in the gap between the through hole on the wall 5 and the pipe body. However, in the fireproof structure of the above-described configuration, the refractory material projects above the first partition material. A thermally expansive refractory sheet may be provided on either the outer peripheral surface of the tubular body or the outer peripheral surface of the tubular body protruding above the second partition member. As a result, better fireproof performance can be exhibited, but in FIG. 1(a), a thermally expansive fireproof sheet is provided on either one of the outer peripheral surfaces of the pipes protruding from the two walls 5. However, the heat-expandable fireproof sheet may be provided on any of the outer peripheral surfaces of the respective pipes protruding from the two walls 5. Thereby, more reliable fireproof performance can be exhibited.
熱膨張性耐火シートは、所定の厚みを有するシート状ないしは板状（例えば０．１ｍｍ〜７．０ｍｍ）であり、管体を挿通できる大きさの開口が形成されている。熱膨張性耐火シートは、壁５の貫通孔よりも一回り大きく形成されており、その形状は、正方形状や円形状など、種々の形状とすることができる。熱膨張性耐火シートは、壁５の貫通孔を遮蔽するように壁５の表面に敷設され、粘着剤、接着剤の他、ねじなどの物理的な固定手段を用いて壁５上に固定される。また、熱膨張性耐火シートには、開口から外周縁に達する切れ込み（図示せず）が設けられている。これにより、区画体の貫通部に挿通されている管体の周囲に対して熱膨張性耐火シートを設置できる。つまり、管体が区画体の貫通部に既に挿通されている場合に、熱膨張性耐火シートを開いた状態として、管体を開口に位置させ、その後、熱膨張性耐火シートを閉じて、壁５上に固定することで、管体の周囲に熱膨張性耐火シートを設けることができる。 The heat-expandable refractory sheet has a sheet shape or a plate shape (for example, 0.1 mm to 7.0 mm) having a predetermined thickness, and has an opening having a size capable of inserting the tubular body. The heat-expandable refractory sheet is formed to be slightly larger than the through hole of the wall 5, and the shape thereof can be various shapes such as a square shape and a circular shape. The heat-expandable refractory sheet is laid on the surface of the wall 5 so as to block the through holes of the wall 5, and is fixed on the wall 5 by using a physical fixing means such as an adhesive or an adhesive and screws. It Further, the thermal expansion refractory sheet is provided with a notch (not shown) reaching from the opening to the outer peripheral edge. Thereby, the heat-expandable refractory sheet can be installed around the pipe body inserted through the penetrating portion of the partition body. That is, when the tubular body is already inserted through the penetrating part of the partition body, the thermal expansive fireproof sheet is opened, the tubular body is positioned at the opening, and then the thermal expansive fireproof sheet is closed to close the wall. By fixing it on 5, the heat-expandable fireproof sheet can be provided around the pipe body.
また、上記構成の防火構造において、耐火材が、前記第１の間仕切り材の貫通孔内及び前記第２の間仕切り材の貫通孔内に充填されていることが好ましい。これにより、より確実な防火性能を発現することができる。 Further, in the fireproof structure having the above-mentioned configuration, it is preferable that the refractory material is filled in the through holes of the first partition material and the through holes of the second partition material. Thereby, more reliable fireproof performance can be exhibited.
また、上記構成の防火構造において、耐火材によって、前記第１の間仕切り材の貫通孔内及び前記第２の間仕切り材の貫通孔内が閉塞されていることが好ましい。これにより、より確実な防火性能を発現することができる。 また、貫通孔と管体との間の隙間が隠されるので、上記隙間を通して双方の室内空間を見えないようにすることができる。 Further, in the fireproof structure having the above structure, it is preferable that the inside of the through hole of the first partition member and the inside of the through hole of the second partition member are closed by a refractory material. Thereby, more reliable fireproof performance can be exhibited. Further, since the gap between the through hole and the tubular body is hidden, it is possible to hide both indoor spaces through the gap.
