Description

本発明は、継手部材に関する。更に、本発明は、オフィスビル、マンション及びデパートなどの建築物の内壁に設置され、火災発生時に消火栓弁を開弁することによって給水管から消火用水を消火用ホースを通じて放水するように構成した消火栓設備及び接続管に関する。 The present invention relates to joint members. Further, the present invention is a fire hydrant installed on the inner wall of buildings such as office buildings, condominiums, department stores, etc., and configured to discharge water for fire extinguishing from a water supply pipe through a fire hose by opening a fire hydrant valve when a fire occurs. Regarding equipment and connecting pipes.

従来から、特許文献１や特許文献２に記載されているように、火災発生に備えて消火活動に使用される消火用ホースやノズル、消火栓弁などを格納してなる消火栓格納箱が知られている。このような消火栓格納箱は、建築物における通路壁等の内壁に設けている格納箱設置空間部内に設置され、内壁の後方側に垂直状に配管された給水管から分岐している接続管の先端部を上記消火栓格納箱の背板に設けている接続管挿通孔を通じて消火栓格納箱内に挿入してその先端部に上記消火栓弁の流入口を接続させる一方、消火栓弁の流出口に上記消火用ホースの基端部を接続することによって消火栓設備を構成している。 Conventionally, as described in Patent Document 1 and Patent Document 2, there has been known a fire hydrant storage box in which fire hoses, nozzles, fire hydrant valves, and the like used for fire extinguishing activities are stored in preparation for the occurrence of a fire. there is Such a fire hydrant storage box is installed in a storage box installation space provided on an inner wall such as a passage wall in a building, and is connected to a connecting pipe branching from a water supply pipe piped vertically on the rear side of the inner wall. The tip end is inserted into the fire hydrant storage box through a connection pipe insertion hole provided in the back plate of the fire hydrant storage box, and the tip end is connected to the inflow port of the fire hydrant valve, while the outflow port of the fire hydrant valve is connected to the fire extinguisher storage box. A fire hydrant facility is constructed by connecting the base end of the fire hose.

又、消火栓格納箱の後方には給水管が配設されており、この給水管から分岐して水平方向に剛直な接続管が配設されており、この接続管の先端部を消火栓格納箱内に引き込み、接続管の先端部に消火栓弁を取り付けている。 In addition, a water supply pipe is arranged behind the fire hydrant storage box. A fire hydrant valve is attached to the tip of the connecting pipe.

上記のように構成した消火設備によれば、消火栓格納箱を建築物の内壁に設置するにあたって、予め、内壁に消火栓格納箱と同形の方形状空間部を設けておき、この空間部内に消火栓格納箱を埋め込み状に収納、固定することによって行われているが、この際、上記消火栓格納箱を設置させるための方形状空間部の位置と、給水管から分岐して水平方向に配設された接続管とが相対的に多少のずれを生じていることがある。 According to the fire extinguishing equipment configured as described above, when installing the fire hydrant storage box on the inner wall of the building, a rectangular space having the same shape as the fire hydrant storage box is provided on the inner wall in advance, and the fire hydrant is stored in this space. This is done by storing and fixing the box in an embedded manner. At this time, the position of the square-shaped space for installing the fire hydrant storage box and the horizontal direction branched from the water supply pipe There may be some relative deviation from the connecting pipe.

そのため、消火栓格納箱を設置する格納箱設置空間部を予め、大きめに形成しておき、格納箱設置空間部内において消火栓格納箱を位置調整することによって、消火栓格納箱の接続管挿入孔と接続管（給水管）との位置ずれを調整することが行われているが、格納箱設置空間部内における消火栓格納箱の位置調整は、労力と時間を要するといった問題点を有する。 Therefore, the storage box installation space for installing the fire hydrant storage box is formed in advance to be large, and by adjusting the position of the fire hydrant storage box in the storage box installation space, the connection pipe insertion hole of the fire hydrant storage box and the connection pipe (Water supply pipe) is adjusted, but there is a problem that the position adjustment of the fire hydrant storage box in the storage box installation space requires labor and time.

特許文献３には、可撓管と、前記可撓管の一端に設けられた消火栓弁と、前記消火栓弁の近傍に固定されたフランジ状の取付板と、前記可撓管の他端に設けられた継手部と、前記消火栓弁が挿通可能で且つ前記取付板より小さい開口面積を有する消火栓弁挿通用孔が裏箱に形成された消火栓格納箱と、を備え、前記消火栓弁挿通用孔に前記消火栓弁が挿通されて前記取付板が前記裏箱に固定され、前記継手部が建物壁の内側に配管された給水管に設けられた分岐継手に接続されている消火設備が提案されており、この消火設備においては、可撓管が用いられている。 Patent Document 3 discloses a flexible tube, a fire hydrant valve provided at one end of the flexible tube, a flange-like mounting plate fixed near the fire hydrant valve, and a and a fire hydrant storage box in which a fire hydrant valve insertion hole through which the fire hydrant valve can be inserted and which has an opening area smaller than that of the mounting plate is formed in the back box, wherein the fire hydrant valve insertion hole A fire extinguishing equipment has been proposed in which the fire hydrant valve is inserted, the mounting plate is fixed to the back box, and the joint portion is connected to a branch joint provided on a water supply pipe piped inside the building wall. A flexible tube is used in this fire extinguishing equipment.

しかしながら、特許文献３の消火設備は、可撓管の漏水の有無を確認するための水圧試験を行なった後、消火栓格納箱を格納箱設置空間部内に配設するまでの間、可撓管は、内壁内の狭い空間部において、基端部を給水管に接続した状態で上方又は側方から垂れ下がった状態となっており、作業者又は作業者が使用する作業道具が、内部に水が充満して既に内部から応力が加わっている状態の可撓管に衝突し、可撓管が破損する虞れがあるという問題点を有する。 However, in the fire extinguishing equipment of Patent Document 3, after a water pressure test for confirming the presence or absence of water leakage in the flexible tube is performed, the flexible tube is placed in the storage box installation space until the fire hydrant storage box is installed. In a narrow space inside the inner wall, the base end is connected to the water supply pipe and hangs down from above or from the side. As a result, it collides with the flexible tube to which stress has already been applied from the inside, and there is a risk that the flexible tube will be damaged.

そこで、可撓管を途中から屈曲させて邪魔にならないように退避させることも考えられるが、可撓管の先端に取り付けられた消火栓弁を閉止した後、可撓管内に水を充満させて所定の圧力を加えて水圧試験を行っており、可撓管内に水が充満しているため、可撓管の可撓性が低下しており、可撓管の屈曲自体が難しく、可撓管を邪魔にならないように退避させることが難しいという問題点を有する。 Therefore, it is conceivable to bend the flexible tube from the middle so that it does not get in the way, but after closing the fire hydrant valve attached to the tip of the flexible tube, the However, since the flexible tube is filled with water, the flexibility of the flexible tube is reduced, making it difficult to bend the flexible tube. It has a problem that it is difficult to retract it out of the way.

又、可撓管内に水が充満し、可撓性が低下した状態で、可撓管を無理に屈曲させると、可撓管が損傷して漏水の原因となる虞れがあるという問題点も有する。 In addition, if the flexible tube is forcibly bent in a state where the flexible tube is filled with water and the flexibility is lowered, the flexible tube may be damaged and cause water leakage. have.

本発明は、管体に介装されて用いられ、管体の先端部を所望位置に位置するように調整することができ且つ管体を退避させることができる継手部材を提供する。又、本発明は、消火栓格納箱の消火栓弁挿入孔と接続管との位置ずれを容易に修正することができる消火栓設備及び接続管を提供する。 SUMMARY OF THE INVENTION The present invention provides a joint member that is used by being inserted in a tubular body, that can adjust the distal end portion of the tubular body to a desired position, and that can retract the tubular body. Further, the present invention provides a fire hydrant installation and a connecting pipe that can easily correct the misalignment between the fire hydrant valve insertion hole of the fire hydrant storage box and the connecting pipe.

一方、第２接続管92における給水管側の開口端部は、継手部材A’の第１継手部材A1における第２部材２の接続部24に接続され、第１継手部材A1の第１部材１の第１流路11に連結、連通している。 On the other hand, the open end portion of the second connecting pipe 92 on the water supply pipe side is connected to the connection portion 24 of the second member 2 of the first joint member A1 of the joint member A', and the first member 1 of the first joint member A1 is connected and communicated with the first channel 11 of the .

従って、第１接続管91及び第２接続管92は、継手部材A’の第１継手部材A1及び第２継手部材A2の第１流路11、11及び第２部材２、２の第２流路23、23を介して連結、連通した状態に接続されている。 Therefore, the first connecting pipe 91 and the second connecting pipe 92 connect the first flow paths 11, 11 of the first joint member A1 and the second joint member A2 of the joint member A' and the second flow paths of the second members 2, 2. Via paths 23, 23, they are connected in a connected and communicative state.

更に、第２接続管92の消火栓弁８側の開口端部は、継手部材Ａの第１部材１における他端開口部16の接続部16aに接続されていると共に、継手部材Ａの第２部材２の接続部24には消火栓弁８が接続されており、第２接続管92及び消火栓弁８は、継手部材Ａの第１部材１の第１流路11及び第２部材２の第２流路23を介して連結、連通した状態に接続されている。なお、消火栓弁８は、第１部材１の一端開口部12に対する第２部材の変位方向が略水平方向に指向した状態に配設された第２部材２の接続部24に接続されている。 Furthermore, the open end of the second connecting pipe 92 on the side of the fire hydrant valve 8 is connected to the connecting portion 16a of the other end opening 16 of the first member 1 of the joint member A, and the second member of the joint member A A fire hydrant valve 8 is connected to the connecting portion 24 of No. 2, and the second connecting pipe 92 and the fire hydrant valve 8 are connected to the first flow path 11 of the first member 1 of the joint member A and the second flow path of the second member 2.

The fire hydrant valve 8 is connected to the connecting portion 24 of the second member 2 arranged such that the displacement direction of the second member with respect to the one end opening 12 of the first member 1 is substantially horizontal.

上述のように、給水管と消火栓弁８とは、継手部材A'、Ａが介在された接続管９によって連結、連通した状態となっており、給水管から供給された消火用水は、接続管９及びこれに介在された継手部材A'、Ａを通じて消火栓弁８に供給可能とされている（分岐管接続工程）。 As described above, the water supply pipe and the fire hydrant valve 8 are connected and communicated by the connection pipe 9 in which the joint members A′ and A are interposed. 9 and the joint members A′ and A interposed therebetween to supply to the fire hydrant valve 8 (branch pipe connecting step).

しかる後、接続管９の先端部に配設した消火栓弁８を閉止した状態とした上で、給水管を通じて接続管９内に水を充満させて水圧試験を行ない、接続管９における漏水の有無を確認する（水圧試験工程）。 After that, with the fire hydrant valve 8 arranged at the tip of the connecting pipe 9 closed, the connecting pipe 9 is filled with water through the water supply pipe and a water pressure test is performed to check for water leakage in the connecting pipe 9. (water pressure test process).

次に、建築物の内壁Ｗに形成された格納箱設置空間部W1内に消火栓格納箱Ｂを配設するが、建築物の他の施工工程との関係で上記水圧試験工程の終了後に消火栓格納箱Ｂが格納箱設置空間部W1内に設置されるまでに時間を要することがある。 Next, the fire hydrant containment box B is installed in the containment box installation space W1 formed in the inner wall W of the building. It may take some time before the box B is installed in the storage box installation space W1.

このような場合、接続管９が格納箱設置空間部W1内に向かって配設されていると、他の施工工程の邪魔になり、又は接続管９に作業者又は作業者が用いる作業道具が衝突して接続管９が破損する虞れがある。 In such a case, if the connecting pipe 9 is arranged toward the storage box installation space W1, it will interfere with other construction processes, or the connecting pipe 9 will interfere with the worker or the work tools used by the worker. There is a risk that the connection pipe 9 will be damaged due to collision.

そこで、接続管９に介在させた継手部材A’の第２継手部材A2の第１部材１を第２部材２及び可動壁部13を中心にして回動させることによって、第２接続管92及びこの第２接続管92の先端部に取り付けた消火栓弁８を上方に向かって退避させて、接続管９及び消火栓弁８の破損を未然に防止することができる。継手部材Ａ、A’において、第１部材１の一端開口部12からの第２部材２の突出長さを固定した状態においても、第１部材１は、第２部材２及び可動壁部13を中心にして回動させることが可能であるので、上記操作を容易に行うことができる。なお、図７において、上方に退避させた第２接続管92及びこの第２接続管92の先端部に取り付けた消火栓弁８を点線で示した。 Therefore, by rotating the first member 1 of the second joint member A2 of the joint member A' interposed in the connecting pipe 9 around the second member 2 and the movable wall portion 13, the second connecting pipe 92 and By retracting the fire hydrant valve 8 attached to the tip of the second connecting pipe 92 upward, the connecting pipe 9 and the fire hydrant valve 8 can be prevented from being damaged. In the joint members A and A', even in a state where the length of projection of the second member 2 from the one end opening 12 of the first member 1 is fixed, the first member 1 keeps the second member 2 and the movable wall portion 13 Since it is possible to rotate around the center, the above operation can be easily performed. In FIG. 7, the second connecting pipe 92 retracted upward and the fire hydrant valve 8 attached to the tip of the second connecting pipe 92 are indicated by dotted lines.

接続管９に水が充満した状態であるが、継手部材Ａ、A’は、接続管９内に充満させた水圧にもかかわらず、継手部材Ａ、A’における第１部材１と第２部材２及び可動壁部13との相対変位を円滑に行なうことができ、接続管９を格納箱設置空間部W1から容易に退避させることができる。 Although the connecting pipe 9 is filled with water, the first member 1 and the second member in the joint members A, A' 2 and the movable wall portion 13 can be smoothly displaced, and the connecting pipe 9 can be easily retracted from the containment box installation space portion W1.

そして、格納箱設置空間部W1内に消火栓格納箱Ｂが配設された後、継手部材A’の第２継手部材A2の第１部材１を第２部材２及び可動壁部13を中心にして回動させることによって、第１接続管91の位置を変化させることなく、上方に退避させている第２接続管92及びこの第２接続管92の先端部に取り付けた消火栓弁８を下方に復帰させ、消火栓弁８を消火栓格納箱Ｂの消火栓弁挿通孔B11に挿通させて消火栓格納箱Ｂ内に配設する（消火栓弁配設工程）（図７参照）。 After the fire hydrant storage box B is installed in the storage box installation space W1, the first member 1 of the second joint member A2 of the joint member A' is moved around the second member 2 and the movable wall portion 13. By rotating, without changing the position of the first connecting pipe 91, the second connecting pipe 92 that has been retracted upward and the fire hydrant valve 8 attached to the tip of the second connecting pipe 92 are returned downward. Then, the fire hydrant valve 8 is inserted into the fire hydrant valve insertion hole B11 of the fire hydrant storage box B and arranged in the fire hydrant storage box B (fire hydrant valve installation process) (see FIG. 7).

一方、格納箱設置空間部W1内に配設した消火栓格納箱Ｂの位置が、当初予定していた配設位置よりも水平方向、上下方向及び／又は前後方向にずれ、その結果、消火栓格納箱Ｂの壁板に形成された消火栓弁挿通孔B11の位置が、予定配設位置Ｌ0から変更配設位置Ｌ1にずれることがある。 On the other hand, the position of the fire hydrant storage box B installed in the storage box installation space W1 shifted horizontally, vertically, and/or in the front-back direction from the originally planned location, and as a result, the fire hydrant storage box The position of the fire hydrant valve insertion hole B11 formed in the wall plate of B may shift from the planned position L0 to the changed position L1.

After that, the projection length of the second member 2 from the one end opening 12 of the first flow path 11 of the first member 1 is adjusted by screwing or retreating the cap body 3 with respect to the cylindrical support portion 15. After that, the fixing pin 32c of the cap body 3 is screwed in the fixing hole 32b and pressed against the outer peripheral surface of the cylindrical support part 15, thereby fixing the cap body 3 to the cylindrical support part 15. This can be done by fixing the projection length of the second member 2 from the one end opening 12 of the first channel 11 of the first member 1 by fixing it in an immovable state.

図６における左右方向の位置調節は、上述と同様の要領で、継手部材A’の第２継手部材A2において、キャップ体３を円筒状支持部15に対して螺進又は螺退させることにより、第１部材１の第１流路11の一端開口部12からの第２部材２の突出長さを調節、固定することによって行なうことができる。 Position adjustment in the left-right direction in FIG. This can be done by adjusting and fixing the projection length of the second member 2 from the one end opening 12 of the first flow path 11 of the first member 1 .

図７における左右方向の位置調節は、上述と同様の要領で、継手部材Ａにおいて、キャップ体３を円筒状支持部15に対して螺進又は螺退させることにより、第１部材１の第１流路11の一端開口部12からの第２部材２の突出長さを調節、固定することによって行なうことができる。 Position adjustment in the left-right direction in FIG. This can be done by adjusting and fixing the projection length of the second member 2 from the one end opening 12 of the channel 11 .

このように、接続管９に介在させた継手部材Ａ、A’のうちの任意の継手部材における第１部材１の第１流路11の一端開口部12からの第２部材２の突出長さを調節することによって、接続管９の先端部に取り付けた消火栓弁８の上下左右方向及び前後方向の位置を正確に且つ容易に調節することができる。 In this way, the projection length of the second member 2 from the one end opening 12 of the first flow path 11 of the first member 1 in any one of the joint members A and A' interposed in the connecting pipe 9 By adjusting , the position of the fire hydrant valve 8 attached to the tip of the connecting pipe 9 can be accurately and easily adjusted in the vertical, horizontal and longitudinal directions.
