Description

本発明は、天井裏に配管されるスプリンクラー用配管に関する。   The present invention relates to a sprinkler pipe to be piped on the back of a ceiling.

スプリンクラー用配管は一般に給水用主管と、該主管に補助管又はヘッダー等を介して接続される巻出し管と、天井に設置されるスプリンクラーヘッドを備え、前記巻出し管の管端部に連結されるヘッド取付管とからなり、消防法の改正により近年、巻出し管に架橋ポリエチレン管等の樹脂管が多用されるようになって来ている。   Sprinkler piping generally includes a water supply main pipe, an unwind pipe connected to the main pipe via an auxiliary pipe or a header, and a sprinkler head installed on the ceiling, and is connected to the pipe end of the unwind pipe. In recent years, resin pipes such as cross-linked polyethylene pipes have been frequently used for unwinding pipes due to revisions to the Fire Service Act.

図1は、特許文献1に開示されるスプリンクラー用配管の一例を示すもので、給水用主管1と、該主管1に接続されるヘッダー2と、天井8(図2)に設置されるスプリンクラーヘッド3を備えたヘッド取付管4と、前記ヘッダー2とヘッド取付管4とを接続する、架橋ポリエチレン管よりなる巻出し管5とよりなり、ヘッド取付管4は図2に示すように、金属部分4aをインサート成形したエルボ継手状をなし、金属部分4aでスラブ6に取付金具7により支持されている。   FIG. 1 shows an example of a sprinkler pipe disclosed in Patent Document 1, a water supply main pipe 1, a header 2 connected to the main pipe 1, and a sprinkler head installed on a ceiling 8 (FIG. 2). 2 and a unwinding pipe 5 made of a cross-linked polyethylene pipe for connecting the header 2 and the head mounting pipe 4, and the head mounting pipe 4 has a metal part as shown in FIG. An elbow joint shape is formed by insert molding 4a, and is supported by a metal fitting 4 on the slab 6 by a metal portion 4a.

特開平10−118219号JP-A-10-118219

巻出し管に樹脂管を用いた場合、巻出し管は天井裏にそのまま置いて這わせておけばよく、金属管のように建物の躯体等に吊り金具で支持する必要がないこと、金属管の場合、天井裏への他の配管、例えば給水・給湯管、雑配水管、汚水管、空調ダクト、電気ケーブルのラック配管などを迂回し、或いは天井に取付けた前記ヘッド取付管に接続できるようにするためエルボ継手を用いて方向転換し、エルボ継手による接続作業のために寸法計測、管の切断、ネジ切り、捩じ込み作業等が必要であるのに対し、樹脂管は概して金属管に比べ可撓性を有するため、エルボ継手を用いなくても方向転換が可能であり、したがってエルボ継手を用いた場合のような前記作業が不要であること等により、施工が容易である利点があるが、火災が発生したとき、スプリンクラーヘッドから散水できるようにするため、巻出し管には、高熱で中までは容易に溶融しないような耐熱性が要求される。   If a resin pipe is used for the unwinding pipe, the unwinding pipe should be placed on the back of the ceiling as it is, and it is not necessary to support it with a hanging bracket on the building frame like a metal pipe. In this case, other pipes on the back of the ceiling, such as water supply / hot water supply pipes, miscellaneous water distribution pipes, sewage pipes, air conditioning ducts, rack pipes for electric cables, etc. can be bypassed or connected to the head mounting pipes mounted on the ceiling. However, resin pipes are generally used as metal pipes, while dimensional measurement, pipe cutting, threading, and screwing work are necessary for the connection work using elbow joints. Compared with flexibility, it is possible to change the direction without using an elbow joint. Therefore, there is an advantage that construction is easy due to the fact that the above-described operation is not necessary as in the case of using an elbow joint. But there was a fire It can, in order to be able watering sprinkler head, the unwinding tube, to medium high fever is easily melted No such heat resistance is required.

そこで従来は、巻出し管に中まで容易には溶融しない肉厚を有する口径の大きなものが用いられているが、肉厚が大で、口径の大きなものは剛性も大きく、曲げ難くなってヘッド取付管への取付作業が容易でない嫌いがあった。   Therefore, in the past, a large-diameter tube having a thickness that does not melt easily to the inside has been used for the unwinding tube. However, a large-wall tube having a large diameter has high rigidity and is difficult to bend. There was a dislike that the mounting work to the mounting pipe was not easy.

本発明は、火災時の送水機能を損なうことなく、ヘッド取付管への取付作業を容易にする巻出し管を備えたスプリンクラー用配管を提供することを目的とする。   An object of this invention is to provide the sprinkler piping provided with the unwinding pipe | tube which makes easy the attachment operation | work to a head attachment pipe | tube, without impairing the water supply function at the time of a fire.

給水用主管と、該主管に補助管又はヘッダー等を介して接続される、可撓性のある樹脂製の巻出し管と、天井に設置されるスプリンクラーヘッドを備え、前記巻出し管の管端部に連結されるヘッド取付管よりなり、天井裏に配管されるスプリンクラー用配管において、前記巻出し管は全長のうち、ヘッド取付管側のヘッド取付管に接続される一部が他の部分に比べ、小径であるか、或いは硬度の低い材質で、剛性が小さく形成されることにより撓みやすくし、しかも前記ヘッド取付管側の一部は、スプリンクラーヘッドからの散水距離以下の長さにされることを特徴とする。
A main pipe for water supply; a flexible resin unwinding pipe connected to the main pipe via an auxiliary pipe or a header; and a sprinkler head installed on the ceiling, the pipe end of the unwinding pipe In the sprinkler piping that is connected to the head and is piped to the back of the ceiling, the unwinding tube is part of the total length that is connected to the head mounting tube on the side of the head mounting tube. compared either a small or a low material hardness, rigidity is easily bent by Rukoto formed small and a part of said head mounting tube side is watering distance less in length from the sprinkler head It is characterized by that.

請求項1に係わる発明によると、巻出し管はスプリンクラーヘッド側の一部が他の部分に比べ、剛性が小さいため、可撓性に富み、ヘッド取付管への取付作業が容易に行えること、剛性が小さくても規定の散水量を確保できること、巻出し管の前記一部はスプリンクラーヘッドからの散水範囲内にあるため、火災時には散水で保護されて中まで溶融しにくく、送水機能を維持できること等の効果を有し、また巻き出し管の一部について、その剛性を低くすることができる
According to the invention relating to claim 1, since the unwinding pipe has a part of the sprinkler head side which is less rigid than the other part, it is rich in flexibility and can be easily attached to the head mounting pipe. Even if the rigidity is small, the specified amount of water can be secured, and since the part of the unwinding pipe is within the watering range from the sprinkler head, it is protected by watering in the event of a fire and is difficult to melt to the inside, and the water supply function can be maintained have a effect etc., and for part of the unwinding tube, it is possible to lower the rigidity thereof.

以下、本発明の実施形態のスプリンクラー用配管について図面により説明する。図中、図1及び図2に示すものと同一構造部分には同一符号を付した。   Hereinafter, piping for sprinklers according to an embodiment of the present invention will be described with reference to the drawings. In the figure, the same structural parts as those shown in FIGS. 1 and 2 are denoted by the same reference numerals.

図1は、本発明が適用されるスプリンクラー用配管の一例であり、図3は、別の例を示すもので、この例のスプリンクラー用配管は、給水用主管11と、該主管11より分岐する複数の補助管12と、天井に設置されるスプリンクラーヘッド13を備えたヘッド取付管14と、前記各補助管12にそれぞれ1ないし複数設けられる多口継手15(ヘッダーでもよい)と前記ヘッド取付管14を連結する、架橋ポリエチレン管よりなる巻出し管16とよりなっている。   FIG. 1 is an example of a sprinkler pipe to which the present invention is applied, and FIG. 3 shows another example. The sprinkler pipe of this example branches from a water supply main pipe 11 and the main pipe 11. A plurality of auxiliary pipes 12, a head mounting pipe 14 provided with a sprinkler head 13 installed on the ceiling, one or more multi-joints 15 (may be headers) provided in each of the auxiliary pipes 12, and the head mounting pipe 14 and an unwinding pipe 16 made of a crosslinked polyethylene pipe.

本発明が適用されるスプリンクラー用配管は、図1及び図3に例示されるものに限らず、給水用主管と該主管に補助管又はヘッダーを介して接続される、可撓性のある樹脂製の巻出し管と、天井に設置されるスプリンクラーヘッドを備え、前記巻出し管の管端部に連結されるヘッド取付管よりなるスプリンクラー用配管を備えたものであればどのような構造のものでもよい。   The sprinkler pipe to which the present invention is applied is not limited to those illustrated in FIGS. 1 and 3, and is made of a flexible resin connected to the main water supply pipe and the main pipe via an auxiliary pipe or a header. Any structure of the unwinding pipe and the sprinkler head installed on the ceiling and having a sprinkler pipe comprising a head mounting pipe connected to the pipe end of the unwinding pipe Good.

巻出し管についても前記した架橋ポリエチレン製のものに限らず、例えば内層が架橋ポリエチレン、外層が非架橋ポリエチレンよりなる2層架橋ポリエチレン管、単なるポリエチレン管或いはポリブテン管等を用いることができる。   The unwinding tube is not limited to the one made of the above-described crosslinked polyethylene, and for example, a two-layer crosslinked polyethylene tube whose inner layer is made of crosslinked polyethylene and an outer layer made of non-crosslinked polyethylene, a simple polyethylene tube or a polybutene tube can be used.

図4は、図1及び図3に示すスプリンクラー用配管における、図2に対応するヘッド取付管4、14に接続される巻出し管21について示すもので、該巻出し管21は、ヘッド取付管側のヘッド取付管4、14に接続される一部21aが小径にされ、他の部分21より剛性が小さくされ、撓み易くなっている。   FIG. 4 shows the unwinding tube 21 connected to the head mounting tubes 4 and 14 corresponding to FIG. 2 in the sprinkler piping shown in FIGS. 1 and 3, and the unwinding tube 21 is a head mounting tube. A part 21a connected to the head mounting pipes 4 and 14 on the side is made smaller in diameter, has a smaller rigidity than the other parts 21, and is easily bent.

前記一部21aの長さはスプリンクラーヘッド13より散布される散水範囲に収まる長さ、すなわち散水距離以下にされ、火災時には散水で保護されて、温度上昇が制限され、これにより中まで溶融し難くなって、送水機能が維持できるようにしてある。   The length of the part 21a is set to be within a watering range sprayed from the sprinkler head 13, that is, a watering distance or less, and is protected by watering in the event of a fire, so that the temperature rise is limited and it is difficult to melt to the inside. Thus, the water supply function can be maintained.

本発明者らは、20mmφの2層架橋ポリエチレン管において、端からの一部の長さ200cmを16mmφとして放水実験を行ったところ、規定放水量の80l/minを確保することができ、20mmφの2層架橋ポリエチレン管とほぼ同等の放水量を確保することができた。   The present inventors conducted a water discharge experiment on a 20-mmφ double-layer cross-linked polyethylene pipe with a part length of 200 cm from the end being 16 mmφ. As a result, the specified water discharge amount of 80 l / min could be secured, and 20 mmφ The amount of water discharged was almost the same as that of the two-layer crosslinked polyethylene pipe.

図5に示す別の実施形態の巻出し管23は端からの一部23aの長さを他部より硬度の低い材質(同材質であっても異種の材質であってもよい)で形成し、剛性を小さくしたものである。   In the unwinding tube 23 of another embodiment shown in FIG. 5, the length of the part 23a from the end is made of a material having a lower hardness than the other part (which may be the same material or a different material). The rigidity is reduced.

巻出し管の一部の剛性を他部より小さくするには、以上の手段のほか、一部の肉厚を他部より薄くしてもよいし、以上の複数の手段のうち、二以上の手段を組合わせてもよい。   In order to make the rigidity of a part of the unwinding tube smaller than the other part, in addition to the above means, a part of the wall thickness may be made thinner than the other part. You may combine a means.
