図５〜図８は、スプリンクラー器具７を天井Ｗに配管する前の状態を示す。図９・図10は、スプリンクラー器具７を天井Ｗに配管した後の状態を示す。 Next, the piping method of the sprinkler piping structure of the present invention will be described.
5 to 8 show a state before the sprinkler device 7 is piped to the ceiling W. FIG. 9 and 10 show a state after the sprinkler device 7 is piped on the ceiling W. FIG.

天井Ｗ裏の基本配管20に、接続されるフレキシブル管３に、挿入用孔部２を有する第１継手11を予め接続して給水側サブユニットＵ1 を形成する。挿入用孔部２へ挿入される挿入筒部６を有する第２継手12に、予め、スプリンクラー器具７を取着したスプリンクラー側サブユニットＵ2 を形成する。 The water supply side subunit U 1 is formed by connecting in advance the first joint 11 having the insertion hole 2 to the flexible pipe 3 connected to the basic pipe 20 behind the ceiling W. The sprinkler side subunit U 2 to which the sprinkler device 7 is attached in advance is formed in the second joint 12 having the insertion cylinder portion 6 inserted into the insertion hole portion 2.

図６・図７に示すように、連結金具16はあらかじめスプリンクラー側サブユニットＵ2 と一体化されている。そして、弾性バネ片部15を有する連結金具16を介して、スプリンクラー側サブユニットＵ2 を、給水側サブユニットＵ1 に、係脱可能に接続する。すなわち、連結金具16の弾性バネ片部15は、上方拡幅状の誘導勾配面18を有する。そして、図３の２点鎖線に示すように、第１継手11の下端縁が弾性バネ片部15を押し広げつつ（弾性変形させつつ）弾性バネ片部15の誘導勾配面18に沿って移動して、スプリンクラー側サブユニットＵ2 を、給水側サブユニットＵ1 に、係脱可能に接続する。 As shown in FIGS. 6 and 7, the connecting fitting 16 is integrated with the sprinkler side subunit U 2 in advance. Then, the sprinkler-side subunit U 2 is detachably connected to the water supply-side subunit U 1 through the coupling metal 16 having the elastic spring piece portion 15. That is, the elastic spring piece portion 15 of the connecting metal fitting 16 has an upwardly widened guiding gradient surface 18. Then, as shown by a two-dot chain line in FIG. 3, the lower end edge of the first joint 11 moves along the guiding gradient surface 18 of the elastic spring piece 15 while expanding (elastically deforming) the elastic spring piece 15. Then, the sprinkler side subunit U 2 is detachably connected to the water supply side subunit U 1 .

なお、スプリンクラー側サブユニットＵ2 を、給水側サブユニットＵ1 に、係脱可能に接続した後に、図示省略の抜止具（例えばスリット付き板片）にて、スプリンクラー側サブユニットＵ2 が天井Ｗから落下しないようにする。 After the sprinkler side subunit U 2 is detachably connected to the water supply side subunit U 1 , the sprinkler side subunit U 2 is connected to the ceiling W by a stopper (not shown) (for example, a plate with a slit). Do not fall from.

本発明は、設計変更可能であって、例えば、弾性バネ片部15の枚数は、２枚、３枚、５枚、６枚等であっても良い。また、シール材５の個数や種類を問わず、２つのシール材５を有する等であっても良い。   The design of the present invention can be changed. For example, the number of elastic spring pieces 15 may be 2, 3, 5, 6, etc. Moreover, it may have two sealing materials 5 regardless of the number and type of the sealing materials 5.

以上のように、本発明は、外周に係止凸部１を有すると共に下方開口部側に挿入用孔部２を有し、かつ、予めフレキシブル管３に螺着される雄ネジ部４を有する天井Ｗ裏側の第１継手11と、挿入用孔部２へ挿入されると共にシール材５を有する挿入筒部６を有し、かつ、予めスプリンクラー器具７が螺着されるネジ孔部８を有し、さらに、外周に外鍔部９を有する第２継手12と、第２継手12の下方外周側から外嵌されて外鍔部９に係止する円形孔13付の軸心直交板部14と、軸心直交板部14から起立して、接続状態で係止凸部１に係合する弾性バネ片部15とを、一体に有する連結金具16と、を具備したので、現場でのスプリンクラー取付作業を容易に行なうことができる。   As described above, the present invention has the locking projection 1 on the outer periphery, the insertion hole 2 on the lower opening side, and the male screw portion 4 that is screwed into the flexible tube 3 in advance. The first joint 11 on the back side of the ceiling W, the insertion tube portion 6 having the sealing material 5 inserted into the insertion hole portion 2 and the screw hole portion 8 into which the sprinkler device 7 is screwed in advance are provided. Furthermore, the second joint 12 having the outer flange portion 9 on the outer periphery, and the axially orthogonal plate portion 14 with the circular hole 13 that is fitted from the lower outer periphery side of the second joint 12 and engages with the outer flange portion 9. And a connecting metal fitting 16 that integrally has an elastic spring piece 15 that stands up from the axial center plate 14 and engages with the locking projection 1 in a connected state. Installation work can be performed easily.

また、係止凸部１が円形外鍔形状であり、かつ、弾性バネ片部15は、切欠窓部17を有し、切欠窓部17の上縁部が、円形外鍔形状の係止凸部１に、係合するように構成したので、簡素な構造でありながら、連結金具16が下方へ離脱することを確実に防止することができる。   Further, the locking projection 1 has a circular outer casing shape, and the elastic spring piece portion 15 has a notch window portion 17, and the upper edge portion of the notch window portion 17 has a circular outer casing shape locking projection. Since the portion 1 is configured to be engaged, it is possible to reliably prevent the connecting metal fitting 16 from being detached downward while having a simple structure.

また、天井Ｗ裏の基本配管20に、接続されるフレキシブル管３に、挿入用孔部２を有する第１継手11を予め接続して給水側サブユニットＵ1 を形成し、挿入用孔部２へ挿入される挿入筒部６を有する第２継手12に、予め、スプリンクラー器具７を取着したスプリンクラー側サブユニットＵ2 を形成し、弾性バネ片部15を有する連結金具16を介して、スプリンクラー側サブユニットＵ2 を、給水側サブユニットＵ1 に、係脱可能に接続するので、現場でのスプリンクラー取付作業を容易に行なうことができる。すなわち、工場に於て、あらかじめ給水側サブユニットＵ1 、及び、スプリンクラー側サブユニットＵ2 の各々を組立て、現場に於て、給水側サブユニットＵ1 にスプリンクラー側サブユニットＵ2 を取付けることができる。 In addition, the first joint 11 having the insertion hole 2 is connected in advance to the flexible pipe 3 connected to the basic pipe 20 behind the ceiling W to form the water supply side subunit U 1 , and the insertion hole 2 The sprinkler side subunit U 2 to which the sprinkler device 7 is attached is formed in advance on the second joint 12 having the insertion cylinder portion 6 to be inserted into the sprinkler, and the sprinkler is connected via the connecting fitting 16 having the elastic spring piece portion 15. Since the side subunit U 2 is detachably connected to the water supply side subunit U 1 , the sprinkler mounting work at the site can be easily performed. That is, in the factory, each of the water supply side subunit U 1 and the sprinkler side subunit U 2 is assembled in advance, and the sprinkler side subunit U 2 can be attached to the water supply side subunit U 1 at the site. it can.
