It is installed.

設備プレート8の凸部16の側面28は、上下方向(図中、X方向)において下方から上方にかけて天井下地材5の縦片部9の側面29から離れる方向に傾斜して形成されており、この凸部16の側面28の傾斜角αは0°<α<90°とし、好ましくはα=80°とする。このように、設備プレート8の凸部16の側面28と天井下地材5の縦片部9の側面29とは所定間隔を有して離間するように構成されている。特に凸部16の側面28上端と天井下地材5の頭部12の側面が上下方向(図中、X方向)に重なる、もしくは凸部16の側面28上端が天井下地材5の頭部12より設備プレート8の中心側に配置されるように設計されている。   The side surface 28 of the convex portion 16 of the equipment plate 8 is formed so as to be inclined in a direction away from the side surface 29 of the vertical piece portion 9 of the ceiling base material 5 from below to above in the vertical direction (X direction in the figure). The inclination angle α of the side surface 28 of the convex portion 16 is 0 ° <α <90 °, and preferably α = 80 °. In this way, the side surface 28 of the convex portion 16 of the equipment plate 8 and the side surface 29 of the vertical piece portion 9 of the ceiling base material 5 are configured to be separated from each other with a predetermined interval. In particular, the upper end of the side surface 28 of the convex portion 16 and the side surface of the head 12 of the ceiling base material 5 overlap in the vertical direction (X direction in the figure), or the upper end of the side surface 28 of the convex portion 16 is from the head 12 of the ceiling base material 5. It is designed to be arranged on the center side of the equipment plate 8.

次に、上記構成についてその作用を説明する。最初に、設備プレート8を介してスプリンクラー等の設備機器を天井裏へ設置する方法について説明する。まず、所望の正方形組6に対して、設備プレート8を天井下地材5の横片部10上部に非固定状態で載置して、設備プレート8の凸部16上面に配設された溝鋼18上部に取付金具21を介して横杆部材22を水平方向に架設する。そして、横杆部材22に取付金具23を介して消火設備24の配管25を固定するとともに、スプリンクラーヘッド26を設備プレート8の貫通部27に設置すると、天井裏への消火設備24の設置が完了する。尚、設置プレート8が設置される正方形組6以外の正方形組6には、天井パネル7が配置される。   Next, the effect | action is demonstrated about the said structure. First, a method of installing equipment such as a sprinkler on the back of the ceiling via the equipment plate 8 will be described. First, the equipment plate 8 is placed in an unfixed state on the upper part of the horizontal piece 10 of the ceiling base material 5 with respect to the desired square group 6, and the groove steel disposed on the upper surface of the convex part 16 of the equipment plate 8. A horizontal reed member 22 is installed in the horizontal direction on the upper part 18 via a mounting bracket 21. Then, the pipe 25 of the fire extinguishing equipment 24 is fixed to the recumbent member 22 via the mounting bracket 23, and when the sprinkler head 26 is installed in the through portion 27 of the equipment plate 8, the installation of the fire extinguishing equipment 24 on the back of the ceiling is completed. To do. A ceiling panel 7 is arranged in the square group 6 other than the square group 6 in which the installation plate 8 is installed.

ここで、設備プレート8は、天井下地材5の横片部10に非固定状態で載置された状態で正方形組6に設置されているため、地震などの揺れに伴い、天井下地材5が脱落しても、設備プレート8は横杆部材22を介して消火設備24の配管25によって吊下げ保持されるため、設備プレート8は天井裏にとどまることが可能である。   Here, since the equipment plate 8 is installed in the square set 6 in a non-fixed state placed on the horizontal piece 10 of the ceiling base material 5, the ceiling base material 5 is moved along with a shake such as an earthquake. Even if it falls off, since the equipment plate 8 is suspended and held by the piping 25 of the fire extinguishing equipment 24 via the recumbent member 22, the equipment plate 8 can remain behind the ceiling.

また、消火設備24の配管25が固定された横杆部材22が、天井下地材5から上下方向(図中、X方向)に所定間隔Hだけ離間した状態で溝鋼18の縁部20に配置されているので、地震などの揺れに伴う天井下地材5の揺れが横杆部材22へ直接的に伝達することを防止して、地震などの揺れから天井裏の消火設備24を保護することができる。   In addition, the recumbent member 22 to which the piping 25 of the fire extinguishing equipment 24 is fixed is arranged on the edge portion 20 of the grooved steel 18 in a state of being separated from the ceiling base material 5 by a predetermined distance H in the vertical direction (X direction in the figure). Therefore, it is possible to prevent the shaking of the ceiling base material 5 accompanying the shaking such as an earthquake from being directly transmitted to the recumbent member 22 and to protect the fire extinguishing equipment 24 on the back of the ceiling from the shaking such as an earthquake. it can.

さらに、設備プレート8の凸部16の側面28が、天井下地材5の縦片部9の側面29から離れる方向に傾斜して形成されているため、地震などの揺れに伴う天井下地材5の水平方向の振動が凸部16へ直接的に伝達されないため、地震などの揺れから消火設備24を保護することができる。   Furthermore, since the side surface 28 of the convex portion 16 of the equipment plate 8 is formed so as to be inclined away from the side surface 29 of the vertical piece 9 of the ceiling base material 5, the ceiling base material 5 of the ceiling base material 5 due to shaking such as an earthquake is formed. Since the horizontal vibration is not directly transmitted to the convex portion 16, the fire extinguishing equipment 24 can be protected from shaking such as an earthquake.

また、設備プレート8の凸部16の側面28が、天井下地材5の縦片部9の側面29から離れる方向に傾斜して形成され、さらに凸部16の側面28上端と天井下地材5の頭部12の側面が上下方向(図中、X方向)に重なる、もしくは凸部16の側面28上端が天井下地材5の頭部12より設備プレート8の内側に配置されるように設計されているため、天井下地材5の頭部12に対して設備プレート8の凸部16は引っ掛かりの少ない形状となっており、地震などの揺れに伴い、天井下地材5が天井裏から脱落する際に、天井下地材5の頭部12に設備プレート8の凸部16が引っ掛かり、設備プレート8ごと天井下地材5が脱落することを防ぐことができる。   Further, the side surface 28 of the convex portion 16 of the equipment plate 8 is formed so as to be inclined away from the side surface 29 of the vertical piece portion 9 of the ceiling base material 5, and the upper end of the side surface 28 of the convex portion 16 and the ceiling base material 5 It is designed so that the side surface of the head 12 overlaps in the vertical direction (X direction in the figure), or the upper end of the side surface 28 of the convex portion 16 is arranged inside the equipment plate 8 from the head 12 of the ceiling base material 5. Therefore, the convex portion 16 of the equipment plate 8 has a shape with little catching with respect to the head 12 of the ceiling base material 5, and when the ceiling base material 5 falls off from the back of the ceiling due to shaking such as an earthquake. It is possible to prevent the projection base 16 of the equipment plate 8 from being caught on the head 12 of the ceiling base material 5 and the ceiling base material 5 from dropping off together with the equipment plate 8.
