従来の消火栓装置は、道路トンネルにおいて、トンネル内の路面の側面位置に形成された監査路上に設置されることが多く、監査路の下方において横引きに配設された配水本管から分岐され、分岐配管を介して消火栓装置が接続されている（特許文献１参照）。 Conventional fire hydrant devices are often installed on an inspection road formed on a side surface position of a road surface in a tunnel in a road tunnel, and are branched from a water distribution main disposed horizontally under the inspection road, A fire hydrant device is connected via a branch pipe (see Patent Document 1).
このように設置される消火栓装置は、消火栓装置をトンネル壁面に形成された箱抜き部分に備え付ける設置作業と同時に、配水本管からの分岐管を接続する配管作業とを行う必要がある。 The fire hydrant apparatus installed in this way needs to perform the piping work for connecting the branch pipe from the water distribution main, simultaneously with the installation work for installing the fire hydrant apparatus in the box opening portion formed on the tunnel wall surface.
上記のような配管作業は、現場において鋼管の切断や位置合わせに接続の作業が必要になり、監査路に設けられた設置スペース内で行うには非常に面倒である。そのため、もっと簡単な作業で設置できる消火栓装置が望まれている。 The above-described piping work requires connection work for cutting and positioning of the steel pipe at the site, and is very troublesome to perform in the installation space provided in the inspection path. Therefore, there is a demand for a fire hydrant device that can be installed by simpler work.
この発明は、簡便に設置できる消火栓装置を得ることを目的としている。 This invention aims at obtaining the fire hydrant apparatus which can be installed simply.
この発明は、先端部にノズルを有する消火用ホースを筐体内に備え、トンネル内に固定設置される消火栓装置において、前記筐体外で下方の監査路内に設けられる配水本管からの分岐部に、消火栓弁と自動調圧弁とを内蔵するとともに、上向きの継手部と下向きの自動排水弁とが前記自動調圧弁の上部と下部とに対向して配置されて一体化された消火栓弁ユニットを、フランジ部を結合して設置し、前記消火栓弁ユニットの二次側から前記消火用ホースまでの間を、一方の継手部を前記消火栓弁ユニットの上向きの継手部に接続し、他方の継手部を前記筐体内に設けられて前記消火用ホースに接続される継手部に接続することで、フレキシブルな配管部材を用いて接続したものであって、前記ノズルからの放水の際には、前記消火栓弁を開放して前記配管部材に、前記自動調圧弁にて所定圧に調圧された消火水を流入させることを特徴とするものである。
The present invention provides a fire hydrant device having a fire hose having a nozzle at a tip portion in a housing and fixedly installed in a tunnel, at a branch portion from a water distribution main provided in a lower inspection path outside the housing. A fire hydrant valve unit that incorporates a fire hydrant valve and an automatic pressure regulating valve, and that is integrated with an upward joint portion and a downward automatic drain valve arranged to face the upper and lower parts of the automatic pressure regulating valve, Installed by connecting the flange part, connecting one joint part to the upward joint part of the fire hydrant valve unit from the secondary side of the fire hydrant valve unit to the fire hose, and the other joint part Connected to a joint portion provided in the casing and connected to the fire-extinguishing hose, and connected using a flexible piping member. When water is discharged from the nozzle, the fire hydrant valve Open It said piping member Te, is characterized in that flowing the extinguishing water pressure regulated to a predetermined pressure by the automatic pressure regulating valve.
さらに、フレキシブルな配管部材は、消火用ホースと同様の接続用ホースである。
Furthermore, the flexible piping member is a connection hose similar to the fire extinguishing hose.
この発明によれば、消火栓弁ユニット側に自動調圧弁を有しているので、自動調圧弁の二次側の部分は所定圧以下の圧力しかかからず、鋼管を用いる必要がなく、消火栓弁ユニットから消火栓装置の筐体までを充水されていないフレキシブルな配管部材で接続するので、保温の作業に加え、配管設置作業まで軽減でき、設置や改修の作業時間を大幅に短縮することができる。 According to the present invention, since the automatic pressure regulating valve is provided on the fire hydrant valve unit side, the secondary side portion of the automatic pressure regulating valve only takes a pressure equal to or lower than a predetermined pressure, and it is not necessary to use a steel pipe. Since the flexible piping member that is not filled with water is connected from the unit to the fire hydrant device housing, it can be reduced to pipe installation work in addition to heat insulation work, and installation and repair work time can be greatly reduced. .
さらに、消火栓弁ユニット以降が所定圧に調圧されているので、配管部材に過度の耐圧性は要求されず、消火用ホースと同等のホースを用いることもできる。また、消火用ホースと同等のホースを用い、着脱部分に同様の継手を用いれば、接続作業が簡便に行える。 Furthermore, since the pressure after the fire hydrant valve unit is regulated to a predetermined pressure, excessive pressure resistance is not required for the piping member, and a hose equivalent to the fire hose can be used. Moreover, if a hose equivalent to a fire extinguishing hose is used and a similar joint is used for the detachable portion, the connection work can be easily performed.
以下、この発明を利用した消火栓装置の実施の形態について説明する。 Hereinafter, an embodiment of a fire hydrant device using the present invention will be described.

FIG. 2 is a front view of the fire hydrant device 2, and its internal configuration is indicated by a dotted line. FIG. 3 is a plan view and a side view showing the internal configuration of the fire hydrant valve unit 5. FIG. 4 is an explanatory diagram relating to the opening / closing mechanism of the fire hydrant valve.
消火栓装置２は、トンネル１内において、路面１２の側方に形成された監査路１３内に埋設された配水本管４から分岐管４１に分岐されて管継手４２を介して消火栓弁ユニット５へ配管され、さらに、この消火栓弁ユニット５から、フレキシブルな配管部材としての接続用ホース６を介して、消火栓本体７内へ接続されている。 The fire hydrant device 2 is branched into a branch pipe 41 from a water distribution main pipe 4 embedded in an inspection path 13 formed on the side of the road surface 12 in the tunnel 1, and is connected to the fire hydrant valve unit 5 via a pipe joint 42. Further, the pipe is connected to the inside of the fire hydrant body 7 from the fire hydrant valve unit 5 through a connection hose 6 as a flexible pipe member.
なお、フレキシブルな配管には、ホース以外に、いわゆるフレキ管などを用いることができる。 In addition to the hose, a so-called flexible pipe can be used for the flexible piping.
この消火栓装置２の設置は、側壁凹部１１に連続して配水本管４からの分岐管４１が設けられている部分に設置用のスペース１４が形成されていて、そのスペース１４内に消火栓弁ユニット５や接続用ホース６を設置すると同時に、側壁凹部１１内の床面に消火栓装置本体７が載置される。 The installation of the fire hydrant apparatus 2 is such that an installation space 14 is formed in a portion where the branch pipe 41 from the water distribution main pipe 4 is provided continuously to the side wall recess 11, and the fire hydrant valve unit is provided in the space 14. 5 and the connecting hose 6 are installed, and the fire hydrant main body 7 is placed on the floor surface in the side wall recess 11.
消火栓本体７は、前面が開放された箱体７１と、その前面を覆う前面パネル７２とで筐体が構成され、その内側に、先端に消火用のノズル７３を有する消火用ホース７４と、その消火用ホース７４を内巻式に収納するホースバケット７５を備えている。この箱体７１は、側壁凹部１１の床面に固定されるベース枠７６にボルト締め等によって固定されている。 The fire hydrant body 7 includes a box 71 having a front surface open and a front panel 72 covering the front surface, and a fire hose 74 having a fire extinguishing nozzle 73 at the tip, A hose bucket 75 that houses the fire-extinguishing hose 74 in an internally wound manner is provided. The box 71 is fixed to a base frame 76 fixed to the floor surface of the side wall recess 11 by bolting or the like.
また、消火栓本体７内には、消火用ホース７４が接続されるとともに、接続用ホース６が接続される継ぎ部材６５を有し、その一端には消防機器用の受け側の継手に構成された継手部６７が設けられている。接続用ホース６の両端は、同じ消防機器用の差込側の継手に構成されているので、継ぎ部材６５への接続が簡便に行える。また、継ぎ部材６５は箱体７１に形成された支持部に支持されていて、継ぎ部材６５には、メンテナンス弁６８が設けられていて、放水試験時に消火用ホース７４に通水せずに十分な消火水の供給を確認できるようになっている。なお、メンテナンス弁６８はなくてもよい。 The fire hydrant body 7 is connected to a fire hose 74 and has a joint member 65 to which the connection hose 6 is connected. One end of the fire hose 74 is configured as a joint on the receiving side for fire fighting equipment. A joint portion 67 is provided. Since both ends of the connecting hose 6 are constructed as joints on the insertion side for the same fire fighting equipment, the connection to the joint member 65 can be easily performed. Further, the joint member 65 is supported by a support portion formed in the box 71, and the joint member 65 is provided with a maintenance valve 68, which is sufficient without passing through the fire hose 74 during a water discharge test. It is possible to check the supply of proper fire extinguishing water. The maintenance valve 68 may not be provided.
前面パネル７２は、扉が設けられる開口を２箇所備え、各開口にはそれぞれ前に倒れる前倒式の消火栓扉７７と横開きの消火器扉７８とが設けられている。この前面パネル７２は左右分割型になっていて双方の上下左右８箇所において、箱体７１の固定部に相当する部分でボルト締めされている。 The front panel 72 is provided with two openings provided with doors, and each opening is provided with a forward-type fire hydrant door 77 and a side-opening fire extinguisher door 78 that fall forward. The front panel 72 is of a left and right divided type, and is bolted at a portion corresponding to a fixing portion of the box 71 at eight places on both the upper, lower, left and right sides.
消火栓扉７７は、前面パネル７２に対して下方を蝶番で結合した手前に回動する扉であり、この消火栓扉７７の開放の際には扉左右のハンドル７９を手前に引くことで、マグネット式の閉状態を維持している磁力による結合をとき、前傾方向に回動して垂れ下がり開口部を開放する。この消火栓扉７７は扉としての機能のみで、軽量かつ簡素である。 The fire hydrant door 77 is a door that rotates to the front panel 72 with a hinge connected to the lower side of the front panel 72. When the fire hydrant door 77 is opened, the handle 79 on the left and right sides of the door is pulled toward the front, When the coupling is performed by the magnetic force maintaining the closed state, it pivots in the forward tilt direction to open the opening. This fire hydrant door 77 has only a function as a door, and is lightweight and simple.
この消火栓扉７７を開放すると、その開口部からノズル７３と開閉レバー８３が露出し、使用者は、開閉レバー８３を開操作してノズル７３を持って消火用ホース７４を引き出しながら火災の発生現場へ向うことにより、ノズル７３から放水して消火活動を行うことができる。 When the fire hydrant door 77 is opened, the nozzle 73 and the opening / closing lever 83 are exposed from the opening, and the user opens the opening / closing lever 83 to hold the nozzle 73 and pull out the fire hose 74 while the fire is occurring. The water can be discharged from the nozzle 73 and fire extinguishing can be performed.
消火器扉７８は、左側に回転軸が形成され横開きに開放し、消火栓扉７７と同様にマグネット式で、右側のハンドル８０を手前に引くことで開放でき、その内側に図示しない消火器が設置される。消火器扉７８の上方には、電気機器取付部が構成され、表示灯８１、発信機８２などの電気機器が取り付けられている。このような消火器部分は別体で構成してもよく、消火栓部分の使用には関係しないので、この発明としてはなくてもよい。 The fire extinguisher door 78 is formed with a rotating shaft on the left side and opened sideways. The fire extinguisher door 78 is a magnet type like the fire hydrant door 77 and can be opened by pulling the right handle 80 toward the front. Installed. Above the fire extinguisher door 78, an electrical device mounting portion is configured, and electrical devices such as an indicator lamp 81 and a transmitter 82 are mounted. Such a fire extinguisher part may be constituted separately and is not related to the use of the fire hydrant part.
消火栓弁ユニット５は、図３に示すような配管系統が構成され、ボール型の開閉弁である消火栓弁５２と、その消火栓弁５２の二次側に配置されて所定圧の消火水を供給する自動調圧弁５３と、同様に消火栓弁５２の二次側に配置されて、詳細に示さないが、放水時でない無加圧の消火水を排出する自動排水弁５８と、分岐管４１に結合されるフランジ部５４と、接続用ホース６が接続される消防機器用の受け側の継手に構成された継手部５５とが一体化されている。 The fire hydrant valve unit 5 has a piping system as shown in FIG. 3 and is arranged on the secondary side of the fire hydrant valve 52, which is a ball-type on-off valve, and supplies fire water with a predetermined pressure. The automatic pressure regulating valve 53 is similarly connected to the branch pipe 41, and is arranged on the secondary side of the fire hydrant valve 52, and is not shown in detail, but discharges unpressurized fire-fighting water that is not discharged. The flange portion 54 and the joint portion 55 configured as a joint on the receiving side for the fire fighting equipment to which the connection hose 6 is connected are integrated.
消火栓弁５２の弁体は、ボックス５６内に配置された連動プーリ５７に連動し、消火栓本体７側で消火栓扉７７の背面側に設けられている開閉レバー８３の操作によって開閉動作される。この開閉レバー８３による消火栓弁５２の開閉機構は、図４に示すように、開閉レバー８３が対向プーリ８４と結合されていて、対向プーリ８４の回転の中心と同軸で、開閉レバー８３が前後に回動するようになっている。そして、開閉レバー８３を引くことによって、同時に対向プーリ８４が回転することになる。この対向プーリ８４にはワイヤ６１が掛けられているとともに、ワイヤ６１は対向プーリ８４に対して一点に係合固定されている。他方、ワイヤ６１は両端を固定されたチューブ６２内を通して消火栓弁５２の連動プーリ５７に掛けられ、このワイヤ６１は連動プーリ５７と対向プーリ８４との間に張設されている。この連動プーリ５７もワイヤ６１と一点において係合固定され、ワイヤ６１の移動と同じ量に連動プーリ５７が回動させられる。この連動プーリ５７の回動とともに、同軸で連動する弁体が消火栓弁５２の開放動作を行うので、消火栓扉７７を開放して、開閉レバー８３を手前に引くことで、消火栓弁ユニット５内の消火栓弁５２を開放することができる。 The valve body of the fire hydrant valve 52 is interlocked with an interlocking pulley 57 disposed in the box 56 and is opened and closed by operating an opening / closing lever 83 provided on the back side of the fire hydrant door 77 on the fire hydrant body 7 side. As shown in FIG. 4, the opening / closing mechanism of the fire hydrant valve 52 by the opening / closing lever 83 is such that the opening / closing lever 83 is coupled to the opposing pulley 84, is coaxial with the center of rotation of the opposing pulley 84, and the opening / closing lever 83 is moved back and forth. It is designed to rotate. By pulling the opening / closing lever 83, the opposing pulley 84 rotates simultaneously. A wire 61 is hung on the opposed pulley 84 and the wire 61 is engaged and fixed to the opposed pulley 84 at one point. On the other hand, the wire 61 is hung on the interlocking pulley 57 of the fire hydrant valve 52 through the tube 62 fixed at both ends, and this wire 61 is stretched between the interlocking pulley 57 and the opposing pulley 84. The interlocking pulley 57 is also engaged and fixed at one point with the wire 61, and the interlocking pulley 57 is rotated by the same amount as the movement of the wire 61. As the interlocking pulley 57 rotates, the coaxially interlocking valve element opens the fire hydrant valve 52. Therefore, by opening the fire hydrant door 77 and pulling the opening / closing lever 83 forward, the inside of the fire hydrant valve unit 5 is opened. The fire hydrant valve 52 can be opened.
ワイヤ６１は、チューブ６２内に通されて、接続用ホース６と同様に、消火栓本体７内から消火栓弁ユニット５内に渡されている。チューブ６２は、余裕のある長さで用意されるが、ワイヤ６１を連動プーリ５７から対向プーリ８４まで張設するには、ワイヤ６１とチューブ６２との長さの関係で決まり、チューブ６２の両端を所定位置に設置すればよい。 The wire 61 is passed through the tube 62 and is passed from the fire hydrant main body 7 to the fire hydrant valve unit 5 in the same manner as the connecting hose 6. The tube 62 is prepared with a sufficient length, but in order to stretch the wire 61 from the interlocking pulley 57 to the opposing pulley 84, it is determined by the relationship between the length of the wire 61 and the tube 62. May be installed at a predetermined position.
このような構成を有する消火栓装置２の設置作業について、以下に説明するが、トンネル１内において、監査路１３内の配水本管４と分岐管４１が予め設置されていて、壁面凹部１１につながる設置用のスペース１４も予め形成されている。 The installation work of the fire hydrant device 2 having such a configuration will be described below. In the tunnel 1, the water distribution main pipe 4 and the branch pipe 41 in the inspection path 13 are installed in advance, leading to the wall surface recess 11. An installation space 14 is also formed in advance.
まず、壁面凹部１１の床面にベース枠７６をアンカーで固定して、その上に消火栓本体７を載置し、ボルト締めによって本体７をベース枠７６に固定する。 First, the base frame 76 is fixed to the floor surface of the wall surface recess 11 with an anchor, the fire hydrant main body 7 is placed thereon, and the main body 7 is fixed to the base frame 76 by bolting.
また、配水本管４から分岐された分岐管４１の管継手４２に消火栓弁ユニット５のフランジ部５４を接続する。 Further, the flange portion 54 of the fire hydrant valve unit 5 is connected to the pipe joint 42 of the branch pipe 41 branched from the water distribution main pipe 4.
つぎに、固定された消火栓本体７内において、箱体７１に設けられた挿通口を通して、接続用ホース６の差込み側の継手部６８を継ぎ部材６５の継手部６６に接続して、箱体７１外の接続用ホース６を設置用のスペース１４を介して消火栓弁ユニット５まで伸ばし、その継手部５５に、接続用ホース６の図示しない差込み側の継手部を接続する。この作業によって簡単に配水本管４と消火栓本体７内の消火用ホース７４を接続することができ、従来のような、鋼管を長さ調整して切断、ねじ切りして、エルボ等を用いて引き回し、ボルト締め等による配管接続等の作業を全く行う必要がなく、接続用ホース６の両端をそれぞれ継手部に接続するだけで配管作業が終わる。 Next, in the fixed fire hydrant main body 7, the joint portion 68 on the insertion side of the connecting hose 6 is connected to the joint portion 66 of the joint member 65 through the insertion port provided in the box body 71, and the box body 71. The external connection hose 6 is extended to the fire hydrant valve unit 5 through the installation space 14, and a joint portion on the insertion side (not shown) of the connection hose 6 is connected to the joint portion 55. By this operation, the water distribution main pipe 4 and the fire hose 74 in the fire hydrant main body 7 can be easily connected. The length of the steel pipe is cut and threaded by adjusting the length as in the conventional case, and is routed using an elbow or the like. There is no need to perform pipe connection work such as bolt tightening, and the pipe work is completed simply by connecting both ends of the connection hose 6 to the joints.
なお、接続用ホース６の長さについては、余裕のある長さが好ましいが、あまり長すぎるとたわみ部が発生して、ホース６内の自然排水が期待できなくなってしまう。そのため、接続用ホース６の長さは消火栓本体７から消火栓弁ユニット５までの間に近い長さにされている。また、接続用ホース６の長さに大きな余裕を持たせた場合、例えば、円筒状の軸体を用意して、螺旋式に巻き取る工夫をすることによって、全体として一方向に傾斜をつけ、たわみ部を発生させずに接続用ホース６内の水を自然排水させることを可能とできる。 In addition, about the length of the hose 6 for connection, although the length with margin is preferable, when too long, a bending part will generate | occur | produce and natural drainage in the hose 6 will become impossible. Therefore, the length of the connecting hose 6 is set to a length close to the portion between the fire hydrant body 7 and the fire hydrant valve unit 5. In addition, when a large margin is given to the length of the connecting hose 6, for example, by preparing a cylindrical shaft body and winding it in a spiral manner, the whole is inclined in one direction, It is possible to allow the water in the connecting hose 6 to be drained naturally without generating a flexure.
また、接続用ホース６と同様に、箱体７１に設けられた挿通口を通して、開閉レバー８３から引き出されるワイヤ６１が通されたチューブ６２を設置用のスペース１４を介して消火栓弁ユニット５まで伸ばし、消火栓弁５２のボックス５６内の連動プーリ５７に接続する。この作業によって簡単に消火栓弁５２の連動プーリ５７と開閉レバー８３の対向プーリ８４を連動させることができ、離れた開閉レバー８３でも消火栓弁５２の開閉操作を行うことができる。 Similarly to the connection hose 6, the tube 62 through which the wire 61 drawn from the opening / closing lever 83 is passed is extended to the fire hydrant valve unit 5 through the installation space 14 through the insertion opening provided in the box 71. , Connected to the interlocking pulley 57 in the box 56 of the fire hydrant valve 52. By this operation, the interlocking pulley 57 of the fire hydrant valve 52 and the opposing pulley 84 of the opening / closing lever 83 can be easily interlocked, and the opening / closing operation of the fire hydrant valve 52 can be performed even by the remote opening / closing lever 83.
このように設置された消火栓装置２は、消火栓弁ユニット５側に自動調圧弁５３を有しているので、自動調圧弁５３の二次側の部分は所定圧以下の圧力しかかからず、鋼管を用いる必要がなく、消火用ホース７４と同等の接続用ホース６を用いることができる。 Since the fire hydrant device 2 installed in this way has the automatic pressure regulating valve 53 on the fire hydrant valve unit 5 side, the secondary side portion of the automatic pressure regulating valve 53 is applied with a pressure equal to or lower than a predetermined pressure. The connection hose 6 equivalent to the fire extinguishing hose 74 can be used.
以上のように、この実施の形態の消火栓装置２では、先端部にノズル７３を有する消火用ホース７４を筐体内に備え、筐体外に設けられる配水本管４からの分岐部に消火栓弁５２を内蔵した消火栓弁ユニット５を設置し、消火栓弁５２の二次側から消火用ホース７４までの間で接続用ホース６を用いて接続したものであって、ノズル７３からの放水の際には、消火栓弁５２を開放して接続用ホース６に消火水を流入させるものであり、内部に充水されない接続用ホース６で接続するので、保温の作業に加え、配管設置作業まで軽減でき、設置や改修の作業時間を大幅に短縮することができる。 As described above, in the fire hydrant device 2 of this embodiment, the fire hose 74 having the nozzle 73 at the tip is provided in the housing, and the fire hydrant valve 52 is provided at the branch from the water distribution main pipe 4 provided outside the housing. A built-in fire hydrant valve unit 5 is installed and connected from the secondary side of the fire hydrant valve 52 to the fire hose 74 using the connection hose 6. When water is discharged from the nozzle 73, The fire hydrant valve 52 is opened to allow the fire water to flow into the connection hose 6. Since the connection hose 6 is not filled with water, the connection hose 6 is connected to the inside of the connection hose 6. The repair work time can be greatly reduced.
さらに、消火栓弁ユニット５は、消火栓弁５２とともに自動排水弁５８および自動調圧弁５３が一体化されていて、また、消火栓本体７内に、両ホース６、７４の継手部を受ける受け部材６５が設けられているものであり、消火栓弁ユニット５以降が所定圧に調圧されているので、接続用ホース６に過度の耐圧性は要求されず、消火用ホース７４と同等のホースを用いることもでき、また、消火用ホース７４と同等のホースを用い、着脱部分に同様の継手を用いれば、接続作業が簡便に行える。 Further, the fire hydrant valve unit 5 has an automatic drain valve 58 and an automatic pressure regulating valve 53 integrated with the fire hydrant valve 52, and a receiving member 65 for receiving the joint portion of both the hoses 6 and 74 is provided in the fire hydrant body 7. Since the fire hydrant valve unit 5 and subsequent parts are regulated to a predetermined pressure, the connection hose 6 is not required to have excessive pressure resistance, and a hose equivalent to the fire hose 74 may be used. In addition, if a hose equivalent to the fire-extinguishing hose 74 is used and a similar joint is used for the detachable portion, the connection work can be easily performed.
