Description

本発明は、消火設備用配管及び消火設備に関する。   The present invention relates to a fire extinguishing equipment pipe and a fire extinguishing equipment.

従来より消火設備用の管材として耐熱塩化ビニル管，架橋ポリエチレン管又はポリブテン等の合成樹脂製の配管が広く採用されている。このような合成樹脂製の配管は、管の切断や管同士の接続における施工性が良く、錆等も発生しないため耐久性が高く、又は消火設備に用いられる管材の運搬が容易となるという利点がある。一方、合成樹脂製の配管は、火炎によって溶融し、消火の機能を果たす前に損壊して漏水させてしまう可能性がある。そこで、耐火性を持たせた消火設備用の配管が各種開発されている（例えば、下記特許文献１）。
特許文献１において開示された耐熱性樹脂管は、架橋ポリエチレン管よりなる合成樹脂管の表層部を金属層とするべく、架橋ポリエチレン管の外周面に薄い柔軟性のある金属製テープを巻き付けて被覆し、耐火性を付与している。 Conventionally, pipes made of synthetic resin such as heat-resistant vinyl chloride pipes, cross-linked polyethylene pipes or polybutene have been widely used as pipe materials for fire extinguishing equipment. Such synthetic resin pipes have good workability in cutting and connecting pipes, have high durability because they do not generate rust, or have the advantage of facilitating transport of pipe materials used in fire extinguishing equipment There is. On the other hand, synthetic resin piping is melted by a flame and may be damaged and leaked before performing a fire extinguishing function. Therefore, various types of piping for fire extinguishing equipment having fire resistance have been developed (for example, Patent Document 1 below).
The heat-resistant resin pipe disclosed in Patent Document 1 is coated by wrapping a thin flexible metal tape around the outer peripheral surface of a crosslinked polyethylene pipe so that the surface layer portion of the synthetic resin pipe made of the crosslinked polyethylene pipe is a metal layer. And fire resistance.

しかし、合成樹脂管の表層部に金属層を設けた配管は、製造において合成樹脂管の成形とは別に金属層を設ける工程が必要となるため、できるだけシンプルな製造工程で耐火性を付与したいという要望があった。
そこで、本発明は、簡便に製造可能でありかつ十分な耐火性を有した消火設備用配管を提供する。 However, piping with a metal layer on the surface layer of a synthetic resin pipe requires a process of providing a metal layer separately from the molding of the synthetic resin pipe in production, so it would be desirable to provide fire resistance with the simplest possible manufacturing process. There was a request.
Therefore, the present invention provides a fire extinguishing equipment pipe that can be easily manufactured and has sufficient fire resistance.

本発明は、上記課題を解決するため、以下の手段を採用する。
本発明の消火設備用配管は、合成樹脂製配管の周方向の少なくとも一部が、前記一部以外の部分よりも厚さ寸法が大きい第１の厚肉部となっており、前記合成樹脂製配管の軸線を中心として前記第１の厚肉部の反対側に位置する対向部が、前記第１の厚肉部及び前記対向部以外の部分よりも厚さ寸法が大きい第２の厚肉部となっており、前記第１の厚肉部又は前記第２の厚肉部の一方を鉛直方向下方に向け、同他方を鉛直方向上方に向け、建物の天井に沿って水平方向に配設可能に形成されていることを特徴とする。
この構成により、本発明の消火設備用配管は、合成樹脂製配管の成形時に簡便に耐火性を付与することができる。また、火災時において、火炎は下方から徐々に天井に及び、天井を伝って広がって、部屋自体も上方が高温になる。従って、天井に配した合成樹脂製配管は下面側のみならず上面側が火炎及び高温の影響を受けやすくなるが、本発明の消火設備用配管は、天井に配した際にその下方側又は上方側の一方を保護することができる。
火炎は先端の方が高温であり、また火炎は天井を伝って広がり部屋自体も上方が高温になるため、天井に配した合成樹脂製配管の下面側及び上面側が火炎や高温の影響を受けるが、上記構成により合成樹脂製配管の下面側及び上面側の双方に対応することができる。 The present invention employs the following means in order to solve the above problems.
Fire extinguishing equipment pipe of the present invention, at least a portion of the circumferential direction of the synthetic resin pipe, has a first thick section thickness dimension is larger than the portion other than said portion, made of the synthetic resin A second thick part having a thickness dimension larger than that of the first thick part and the part other than the opposing part, the opposing part located on the opposite side of the first thick part with respect to the axis of the pipe It can be arranged horizontally along the ceiling of the building, with one of the first thick part or the second thick part facing downward in the vertical direction and the other facing upward in the vertical direction. It is characterized by being formed.
With this configuration, the fire-extinguishing equipment pipe of the present invention can easily impart fire resistance when molding a synthetic resin pipe. In the event of a fire, the flame gradually spreads from below to the ceiling and spreads along the ceiling, and the room itself becomes hot at the top. Therefore, the synthetic resin piping arranged on the ceiling is susceptible to the influence of flame and high temperature on the upper surface side as well as the lower surface side, but the fire extinguishing equipment piping of the present invention has its lower side or upper side when arranged on the ceiling. One of them can be protected.

Therefore, the synthetic resin piping arranged on the ceiling is susceptible to the influence of flame and high temperature on the upper surface side as well as the lower surface side, but the fire extinguishing equipment piping of the present invention has its lower side or upper side when arranged on the ceiling. One of them can be protected. And a thick-walled part can be easily formed and fire resistance can be imparted by shifting the axis of the inner peripheral surface of the synthetic resin pipe and the axis of the outer peripheral surface.

本発明の前記第１の厚肉部及び前記第２の厚肉部は、前記合成樹脂製配管の外形及び内形の少なくとも一方を断面視楕円形にして形成されていてもよい。
この構成により、本発明の消火設備用配管は、第１の厚肉部及び第２の厚肉部を簡便に形成し耐火性を付与することができる。 The first thick portion and the second thick portion of the present invention may be formed such that at least one of an outer shape and an inner shape of the synthetic resin pipe is elliptical in cross section.
With this configuration, the pipe for fire extinguishing equipment of the present invention can easily form the first thick part and the second thick part and impart fire resistance.

本発明の消火設備は、上記いずれかの消火設備用配管を、前記第１の厚肉部を鉛直方向下方又は上方に向けて前記天井に配設していることを特徴とする。
この構成により、消火設備に耐火性を付与することができる。 The fire-extinguishing equipment of the present invention is characterized in that any one of the above-mentioned pipes for fire-extinguishing equipment is arranged on the ceiling with the first thick portion facing vertically downward or upward.

When the fire-extinguishing equipment pipe 2, the sprinkler head 4 and the cheese 3 for connecting them are arranged in the ceiling 6a, the sprinkler head 4 inserts an injection portion into a through hole 7 formed in the ceiling 6 to inject The section is installed indoors.

消火設備用配管２は、塩化ビニル管や塩素化塩化ビニル管，ポリエチレン管，架橋ポリエチレン管等の合成樹脂材料を用いた配管により形成されている。   The fire extinguishing equipment pipe 2 is formed by a pipe using a synthetic resin material such as a vinyl chloride pipe, a chlorinated vinyl chloride pipe, a polyethylene pipe, or a crosslinked polyethylene pipe.

図２に示すように、消火用液を送水する合成樹脂製配管（以下、単に「配管」という）２ａの内周面１０の軸線Ｌ１は、外周面１１の軸線Ｌ２に対して偏芯して形成されている。軸線Ｌ１と軸線Ｌ２とを結んだ線上の位置Ｐ１を中心とする配管２ａの周方向の一部１２は、第１の厚肉部となっており（以下、「位置Ｐ１を中心とする配管２ａの周方向の一部１２」を「第１の厚肉部１２」ともいう）、第１の厚肉部１２以外の部分よりも厚さ寸法が大きく形成されている。言い換えると、配管２ａは、厚肉に形成された第１の厚肉部１２と第１の厚肉部１２よりも薄肉に形成された部分とにより形成されている。また、第１の厚肉部１２は、配管２ａにおいて最も厚肉に形成された位置Ｐ１を中心に時計回りに９０度の位置Ｐ２から反時計回りに９０度の位置Ｐ３に亘って形成されている。   As shown in FIG. 2, the axis L1 of the inner peripheral surface 10 of the synthetic resin pipe (hereinafter simply referred to as “pipe”) 2a for feeding the fire-extinguishing liquid is eccentric with respect to the axis L2 of the outer peripheral surface 11. Is formed. A portion 12 in the circumferential direction of the pipe 2a centering on the position P1 on the line connecting the axis L1 and the axis L2 is a first thick portion (hereinafter referred to as “pipe 2a centering on the position P1”). The circumferential portion 12 "is also referred to as" first thick portion 12 "), and the thickness dimension is larger than the portion other than the first thick portion 12. In other words, the pipe 2 a is formed by the first thick portion 12 formed to be thick and the portion formed to be thinner than the first thick portion 12. Further, the first thick portion 12 is formed from a position P2 of 90 degrees clockwise from a position P1 formed to be the thickest in the pipe 2a to a position P3 of 90 degrees counterclockwise. Yes.

配管２ａのうち最も薄肉である位置Ｐ４には、鉛直方向上方又は下方に向ける位置を示す表示１３が設けられている。
以上の構成を有する消火設備用配管２は、本実施形態では最も厚肉となっている位置Ｐ１が最下点に位置するように図１に示す天井６又は天井裏６ａに配される（以下、厚肉となっている「位置Ｐ１」を「最下点Ｐ１」とも言う）。 A display 13 indicating a position directed upward or downward in the vertical direction is provided at the thinnest position P4 in the pipe 2a.
The fire extinguishing equipment pipe 2 having the above configuration is arranged on the ceiling 6 or the ceiling back 6a shown in FIG. 1 so that the thickest position P1 is located at the lowest point in the present embodiment (hereinafter referred to as the following). The thick “position P1” is also referred to as “the lowest point P1”).

このように、消火設備用配管２は、配管２ａの位置Ｐ１を中心とする配管２ａの周方向の一部を第１の厚肉部１２として、表示１３を以って、第１の厚肉部１２を鉛直方向下方に向けて天井６に配設可能に形成されている。そして、消火設備１（図１を参照。以下同様）は、消火設備用配管２の第１の厚肉部１２を鉛直方向下方に向けて配設しているため、下方から火炎が回っても配管２ａが溶融して配管２ａに孔が開く等の損壊を生じるまでに時間を稼ぐことができる。したがって、消火設備用配管２及び消火設備１は、消火設備１が作動する前に消火設備１の機能を損なわせてしまうということを防止することができるという効果を奏する。   In this way, the fire extinguishing equipment pipe 2 has the first thick part 12 with the display 13 with a part in the circumferential direction of the pipe 2a centered on the position P1 of the pipe 2a as the first thick part 12. It is formed so that the part 12 can be disposed on the ceiling 6 with the vertical direction downward. And since the fire extinguishing equipment 1 (refer FIG. 1 and the following is the same) arrange | positions the 1st thick part 12 of the piping 2 for fire extinguishing equipment toward the perpendicular direction downward, even if a flame turns from the downward direction Time can be gained until the pipe 2a is melted and damage such as a hole is opened in the pipe 2a. Therefore, the fire extinguishing equipment pipe 2 and the fire extinguishing equipment 1 have an effect that it is possible to prevent the function of the fire extinguishing equipment 1 from being impaired before the fire extinguishing equipment 1 operates.

（第１の実施形態の変形例１）
次に、消火設備用配管２及び消火設備１の第１の実施形態の変形例１について図３を用いて説明する。第１の実施形態の変形例１の消火設備用配管２は、第１の厚肉部１２に中空部１５が形成されている。 (Modification 1 of the first embodiment)
Next, Modification 1 of the first embodiment of the fire extinguishing equipment pipe 2 and the fire extinguishing equipment 1 will be described with reference to FIG. In the fire-extinguishing equipment pipe 2 of Modification 1 of the first embodiment, a hollow portion 15 is formed in the first thick portion 12.

中空部１５は、配管２ａの軸線Ｌ２方向に直交する断面視で水平方向に長い楕円形に形成されており、配管２ａの長手方向（紙面奥行き方向）に延在するように形成されている。その結果、内周面１０により形成された管路１６と中空部１５との間には、第１の厚肉部１２の一部により形成された隔壁部１７が形成されている。なお、中空部１５は、配管２ａの長手方向の一端から他端に向かって連続的に形成されていても、間欠的に複数形成されていてもよい。この中空部１５は、第１の厚肉部１２内に空気層を形成することで断熱機能を付与している。   The hollow portion 15 is formed in an oval shape that is long in the horizontal direction in a cross-sectional view orthogonal to the direction of the axis L2 of the pipe 2a, and is formed so as to extend in the longitudinal direction of the pipe 2a (the depth direction in the drawing). As a result, a partition wall portion 17 formed by a part of the first thick portion 12 is formed between the pipe line 16 formed by the inner peripheral surface 10 and the hollow portion 15. The hollow portion 15 may be formed continuously from one end to the other end in the longitudinal direction of the pipe 2a, or a plurality of the hollow portions 15 may be formed intermittently. The hollow portion 15 imparts a heat insulating function by forming an air layer in the first thick portion 12.

以上の構成により、第１実施形態の変形例１の第１の厚肉部１２は、消火設備用配管２の下方から火炎が回っても中空部１５の断熱機能により、隔壁部１７の温度上昇を抑制することができる。したがって、第１の実施形態の変形例１の消火設備用配管２及び消火設備１は、耐火性が一層高まり、火災により消火設備１が作動する前に配管２ａが損壊することを一層効果的に防止することができるという効果を奏する。また、消火設備用配管２は、配管２ａの成形時に中空部１５を形成すればよいため、簡便に製造することができるという効果を奏する。なお、中空部１５の形状は、楕円形に限らず正円形でもその他の多角形に形成されたものであってもよい。   With the above configuration, the first thick portion 12 of the first modification of the first embodiment has a temperature increase of the partition wall portion 17 due to the heat insulating function of the hollow portion 15 even when a flame turns from below the fire extinguishing equipment pipe 2. Can be suppressed. Therefore, the fire-extinguishing equipment pipe 2 and the fire-extinguishing equipment 1 of the first modification of the first embodiment are further improved in fire resistance, and the pipe 2a is more effectively damaged before the fire-extinguishing equipment 1 is activated due to a fire. There is an effect that it can be prevented. Moreover, since the piping 2 for fire extinguishing equipment should just form the hollow part 15 at the time of shaping | molding of the piping 2a, there exists an effect that it can manufacture simply. The shape of the hollow portion 15 is not limited to an ellipse, and may be a regular circle or other polygons.

（第１の実施形態の変形例２）
次に、消火設備用配管２及び消火設備１の第１の実施形態の変形例２について図４を用いて説明する。第１の実施形態の変形例２の消火設備用配管２は、図４に示すように、第１の厚肉部１２に形成された中空部１５に水Ｘ１又は消火剤Ｘ２が挿入されている。 (Modification 2 of the first embodiment)
Next, Modification 2 of the first embodiment of the fire extinguishing equipment pipe 2 and the fire extinguishing equipment 1 will be described with reference to FIG. As shown in FIG. 4, the fire extinguishing equipment pipe 2 of Modification 2 of the first embodiment has water X1 or fire extinguishing agent X2 inserted in the hollow portion 15 formed in the first thick portion 12. .

本変形例２において、中空部１５は、配管２ａの一端から他端に亘って連続して形成されており、水Ｘ１又は消火剤Ｘ２を挿入した上で封止されている。
以上の構成により、消火設備用配管２及び消火設備１は、中空部１５に水Ｘ１が充填されている場合には、第１の厚肉部１２の温度上昇を抑制して配管２ａの損壊を効果的に防止することができるという効果を奏する。 In the second modification, the hollow portion 15 is continuously formed from one end to the other end of the pipe 2a, and is sealed after inserting the water X1 or the fire extinguishing agent X2.
With the above configuration, when the hollow portion 15 is filled with water X1, the fire extinguishing equipment pipe 2 and the fire extinguishing equipment 1 suppress the temperature rise of the first thick part 12 and damage the pipe 2a. There exists an effect that it can prevent effectively.

また、消火設備用配管２及び消火設備１は、中空部１５に消火剤Ｘ２が充填されている場合には、火炎により中空部１５の外周面１１側に位置する第１の厚肉部１２の一部１８に孔が開いたり破断したりした際に、消火剤Ｘ２を投下して火災の鎮静化を補助することができる。また、消火設備用配管２及び消火設備１は、中空部１５の隔壁部１７側の壁面１７ａに消火剤が付着しているため、隔壁部１７の延焼を効果的に防止し、火災時に消火設備用配管２及び消火設備１をより効果的に維持することができるという効果を奏する。   In addition, when the hollow part 15 is filled with the extinguishing agent X2, the fire extinguishing equipment pipe 2 and the fire extinguishing equipment 1 have the first thick part 12 positioned on the outer peripheral surface 11 side of the hollow part 15 by the flame. When a hole is opened or broken in the part 18, the fire extinguishing agent X2 can be dropped to assist in calming the fire. In addition, the fire extinguishing equipment pipe 2 and the fire extinguishing equipment 1 have the fire extinguishing agent attached to the wall surface 17a of the hollow portion 15 on the side of the partition wall portion 17a. There exists an effect that the piping 2 for fireworks and the fire extinguishing equipment 1 can be maintained more effectively.

また更に、消火設備用配管２は、位置Ｐ１を鉛直方向下方に向けて配される構成となっているが、位置Ｐ１を鉛直方向上方に向けて配されるものであってもよい。   Furthermore, although the fire extinguishing equipment pipe 2 has a configuration in which the position P1 is arranged downward in the vertical direction, the pipe 2 may be arranged in such a manner that the position P1 is directed upward in the vertical direction.

次に、本発明の第２の実施形態について図５を用いて説明する。本実施形態において第１の実施形態と同一の構成については同一の符号を付し、その説明を省略する。
本実施形態の消火設備用配管２０及び消火設備１は、少なくとも第１の厚肉部１２の最下点Ｐ１側の肉部１９が、配管２０ａのそれ以外の部分の樹脂材料よりも融点が高い樹脂材料を含んで一体的に成形されている。この構成において最下点Ｐ１側の肉部は延焼防止部１９を構成している。 Next, a second embodiment of the present invention will be described with reference to FIG. In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.
In the fire extinguishing equipment pipe 20 and the fire extinguishing equipment 1 of the present embodiment, at least the meat portion 19 on the lowest point P1 side of the first thick portion 12 has a higher melting point than the resin material of the other portion of the pipe 20a. It is molded integrally including a resin material. In this configuration, the meat part on the lowest point P1 side constitutes the fire spread prevention part 19.

延焼防止部１９は、具体的には、架橋ポリエチレン管よりも融点の高い材料や、燃焼時に有毒なガスが出ない材料で形成されていることが好ましく、消火設備用配管２と同じ合成樹脂材料に耐火性や難燃性を有する材料を配合した樹脂材料を用いるのが成形性や製造上の点で好ましい。   Specifically, the fire spread prevention unit 19 is preferably made of a material having a melting point higher than that of the crosslinked polyethylene pipe or a material that does not emit toxic gas during combustion, and is the same synthetic resin material as the fire extinguishing equipment pipe 2. It is preferable in terms of moldability and production to use a resin material containing a material having fire resistance and flame retardancy.

耐火性や難燃性を有する材料としては燃焼時の難燃性を高めるためのものであれば特に限定されるものではないが、例えば、水酸化アルミニウム、水酸化マグネシウム等の水酸化物、ハイドロタルサイト、二酸化アンチモン、三酸化アンチモン、五酸化アンチモン等の酸化アンチモン、三酸化モリブデン、二硫化モリブデン、アンモニウムモリブデート等のモリブデン化合物、テトラブロモビスフェノールＡ、テトラブロムエタン、テトラブロムエタン、テトラブロムエタン等の臭素系化合物、トリフェニルフォスフェート、アンモニウムポリフォスフェート等のリン系化合物、ホウ酸カルシウム、ホウ酸亜鉛などが挙げられる。   The material having fire resistance and flame retardancy is not particularly limited as long as it is intended to enhance the flame retardancy during combustion. For example, hydroxides such as aluminum hydroxide and magnesium hydroxide, hydro Antimony oxides such as talcite, antimony dioxide, antimony trioxide, antimony pentoxide, molybdenum compounds such as molybdenum trioxide, molybdenum disulfide, ammonium molybdate, tetrabromobisphenol A, tetrabromoethane, tetrabromoethane, tetrabromethane Bromine compounds such as triphenyl phosphate and ammonium polyphosphate, calcium borate, zinc borate and the like.

また、熱により膨張して耐火性を発現する材料を用いても良く、例えば、膨張性黒鉛、ホウ砂ひる石、パーライトなどの無機系膨張剤や、アゾジカルボンアミド、アゾジアミノベンゼン、Ｎ，Ｎ’−ジニトロソ−Ｎ，Ｎ’−ジメチルテレフタルアミド、ベンゼンスルホニルヒドラジド、ｐ，ｐ’−オキシビスベンゼンスルホニルヒドラジドなどの有機系膨張剤が挙げられる。   In addition, a material that expands by heat and exhibits fire resistance may be used. For example, an inorganic expansion agent such as expansive graphite, borax granite, perlite, azodicarbonamide, azodiaminobenzene, N, N Organic swelling agents such as' -dinitroso-N, N'-dimethyl terephthalamide, benzenesulfonyl hydrazide, and p, p'-oxybisbenzenesulfonyl hydrazide may be mentioned.

この構成により、消火設備用配管２０及び消火設備１は、火災時に配管２０ａへの延焼を防止することができるため、消火設備１が作動するまで消火設備用配管２０を損傷させることを防止することができるという効果が得られる。   With this configuration, the fire-extinguishing equipment pipe 20 and the fire-extinguishing equipment 1 can prevent the fire 20 from spreading to the pipe 20a in the event of a fire, and therefore prevent the fire-extinguishing equipment pipe 20 from being damaged until the fire-extinguishing equipment 1 operates.

次に、本発明の第３の実施形態について図６を用いて説明する。本実施形態において第１の実施形態又は第２の実施形態と同一の構成については同一の符号を付し、その説明を省略する。
本実施形態の消火設備用配管３０及び消火設備１は、配管３０ａの軸線Ｌ１（Ｌ２）を中心として第１の厚肉部１２の反対側に位置する対向部１４が、第１の厚肉部１２又は対向部１４以外の部分（具体的には配管３０ａが天井６に配された際の管側部３１，３１）よりも厚さ寸法が大きい第２の厚肉部（以下、「対向部１４」を「第２の肉厚部１４」ともいう）となっている。 Next, a third embodiment of the present invention will be described with reference to FIG. In the present embodiment, the same components as those in the first embodiment or the second embodiment are denoted by the same reference numerals, and the description thereof is omitted.
In the fire extinguishing equipment pipe 30 and the fire extinguishing equipment 1 of the present embodiment, the facing portion 14 located on the opposite side of the first thick portion 12 around the axis L1 (L2) of the piping 30a is the first thick portion. 12 or a portion other than the facing portion 14 (specifically, the pipe-side portions 31 and 31 when the pipe 30a is arranged on the ceiling 6) is a second thick portion (hereinafter referred to as “facing portion”). 14 "is also referred to as" second thick portion 14 ").

言い換えると、配管３０ａは、第１の厚肉部１２と軸線Ｌ１を中心とする反対側に第２の厚肉部１４とを備え、これら第１の厚肉部１２と第２の厚肉部１４との間に薄肉部となる管側部３１，３１を備えている。
そして、消火設備用配管３０及び消火設備１は、第１の厚肉部１２を鉛直方向下方に向け、第２の厚肉部１４を鉛直方向上方に向け（すなわち天井６に対向配置させて）、天井６に沿って水平方向に配設されている。なお、消火設備用配管３０及び消火設備１は、第２の厚肉部１４を鉛直方向下方に向け、第１の厚肉部１２を鉛直方向上方に向け（すなわち天井６に対向配置させて）、天井６に沿って水平方向に配設されていてもよい。 In other words, the pipe 30a includes the first thick portion 12 and the second thick portion 14 on the opposite side with the axis L1 as the center, and the first thick portion 12 and the second thick portion. 14 are provided with pipe side portions 31 and 31 which are thin-walled portions.
And the piping 30 for fire extinguishing equipment and the fire extinguishing equipment 1 make the 1st thick part 12 face the perpendicular direction downward, and the 2nd thick part 14 face the vertical direction upward (namely, it is made to oppose the ceiling 6). In the horizontal direction along the ceiling 6. The fire extinguishing equipment pipe 30 and the fire extinguishing equipment 1 have the second thick portion 14 directed downward in the vertical direction and the first thick portion 12 directed upward in the vertical direction (that is, arranged opposite to the ceiling 6). Further, it may be arranged in the horizontal direction along the ceiling 6.

本実施形態において、配管３０ａの外周面１１の断面形状は鉛直方向に長い楕円形に形成され、内周面１０の断面形状は略正円に形成され、外周面１１の軸線Ｌ１と内周面１０の軸線Ｌ２とを一致させている。配管３０ａをこのように構成することにより、第１の厚肉部１２と第２の厚肉部１４とが形成されている。
また、位置Ｐ１及び位置Ｐ４のいずれか一方（双方であってもよい）に鉛直方向上方又は下方に向けるべき方向を示す表示１３が形成されている。 In the present embodiment, the cross-sectional shape of the outer peripheral surface 11 of the pipe 30a is formed in an elliptical shape that is long in the vertical direction, the cross-sectional shape of the inner peripheral surface 10 is formed in a substantially perfect circle, and the axis L1 of the outer peripheral surface 11 and the inner peripheral surface Ten axis lines L2 coincide with each other. By configuring the pipe 30a in this way, the first thick part 12 and the second thick part 14 are formed.
In addition, a display 13 indicating a direction to be directed upward or downward in the vertical direction is formed at one of the positions P1 and P4 (or both).

火災が発生した場合、火炎は先ず第１の厚肉部１２に達し、その後、最も高温になる火炎の先端は配管３０ａを覆った際に第２の厚肉部１４に及ぶため、第１の厚肉部１２と第２の厚肉部１４とが配管３０ａの側部よりも早く燃焼する傾向がある。
しかし、消火設備用配管３０及び消火設備１は、配管３０ａの位置Ｐ１を中心とする第１の厚肉部１２及び位置Ｐ４を中心とする第２の厚肉部１４を厚肉に形成しているため、燃焼が早い傾向のある部分を有効に保護することができるという効果を奏する。 When a fire occurs, the flame first reaches the first thick portion 12, and then the tip of the highest temperature flame reaches the second thick portion 14 when the pipe 30a is covered. The thick part 12 and the second thick part 14 tend to burn faster than the side part of the pipe 30a.
However, the fire-extinguishing equipment pipe 30 and the fire-extinguishing equipment 1 are formed by thickening the first thick part 12 centered on the position P1 of the pipe 30a and the second thick part 14 centered on the position P4. Therefore, there is an effect that it is possible to effectively protect the portion that tends to burn quickly.

なお、本実施形態において、第１の厚肉部１２と第２の厚肉部１４とは、外周面１１の断面形状を略正円とし、内周面１０の断面形状を水平方向に長い楕円形にして形成したものであってもよい。
