JP-A-5-233975

小型で軽い火災感知器であれば、従来技術のような回転係合方式でも容易に火災感知器を取り付けることができる。しかし、特殊な用途によって、火災感知器が大型で重量が重い場合には、回転係合方式だと、取付作業が面倒であった。   If it is a small and light fire detector, the fire detector can be easily attached even by the rotational engagement method as in the prior art. However, when the fire detector is large and heavy due to special applications, the rotating engagement method makes installation work troublesome.

そこで、本発明は、火災感知器が重くても、天井への取付作業を容易に行うことができるようにすることを目的とする。   In view of the above, an object of the present invention is to make it possible to easily perform an installation work on a ceiling even if a fire detector is heavy.

本発明は以上の課題を解決するためになされたもので、天井に取り付けられる本体と、該本体に設けられ、火災感知器がスライドして取り付けられるレール部材とにより火災感知器の取付具を構成し、火災感知器に取付用のアングル部を設け、該アングル部を前記レール部材にスライドして取り付けることを特徴とするものである。   The present invention has been made in order to solve the above problems, and comprises a fire detector mounting tool comprising a main body attached to a ceiling and a rail member provided on the main body and to which a fire detector slides. In addition, the fire detector is provided with an angle portion for attachment, and the angle portion is slid and attached to the rail member.

取付具を、天井に取り付けられる本体と、火災感知器がスライドして取り付けられるレール部材とから構成し、火災感知器に取付用のアングル部を設け、アングル部をレール部材にスライドして取り付けるようにしたので、火災感知器の重量が重くても、容易に火災感知器を取付具を介して天井へ取り付けることができる。本体を構成する箱体の側面に配線引出孔を設けたので、天井下面に配線を這わすことができる。   The fixture is composed of a main body that can be mounted on the ceiling and a rail member on which the fire detector is slid. The angle portion for mounting is provided on the fire detector, and the angle portion is slid onto the rail member. Therefore, even if the fire detector is heavy, the fire detector can be easily attached to the ceiling via the fixture. Since the wiring lead-out hole is provided on the side surface of the box constituting the main body, the wiring can be routed on the lower surface of the ceiling.

図１は本発明の火災感知器の取付具の斜視図である。図２は図１のＡ−Ａ線断面図である。図３は火災感知器を背面側（天井設置側）からみた斜視図である。
図において、１は金属板などを折り曲げ加工して作られた、火災感知器の取付具で、天井に取り付けられる本体３から構成され、本体３は下面に開口部５を備えた箱体からなる。 FIG. 1 is a perspective view of a fire detector fixture according to the present invention. 2 is a cross-sectional view taken along line AA in FIG. FIG. 3 is a perspective view of the fire detector as viewed from the back side (ceiling installation side).
In the figure, 1 is a fire detector fixture made by bending a metal plate or the like, and is composed of a main body 3 attached to the ceiling, and the main body 3 is made of a box body having an opening 5 on the lower surface. .

箱体３の下部に設けられた底板７には、火災感知器がスライドして取り付けられる２本のレール部材９が設けられる。レール部材９は、底板７の縁部に設けられ、開口部５の幅とほぼ等しい長さを有している。図２に示すように、レール部材は、箱体３と別部材で構成され溶接などにより固定されているが、箱体３と同じ部材で一体に加工してもよい。レール部材９は、断面Ｌ型のアングル形状となっており、レール部材９と底板７のわずかな隙間に、後述する火災感知器のアングル部が入るようになっている。底板７上において、レール部材９の両端には、取付穴１０が形成されている。この取付穴１０において、箱体３の裏側には、ナットが溶接で固着されている。   Two rail members 9 to which the fire detector is slid and attached are provided on the bottom plate 7 provided at the lower portion of the box 3. The rail member 9 is provided at the edge of the bottom plate 7 and has a length substantially equal to the width of the opening 5. As shown in FIG. 2, the rail member is composed of a separate member from the box 3 and is fixed by welding or the like, but may be integrally processed with the same member as the box 3. The rail member 9 has an L shape with an L-shaped cross section, and an angle portion of a fire detector, which will be described later, enters a slight gap between the rail member 9 and the bottom plate 7. On the bottom plate 7, mounting holes 10 are formed at both ends of the rail member 9. In the mounting hole 10, a nut is fixed to the back side of the box 3 by welding.

箱体３の上方側部には、フランジ１１が設けられる。フランジ１１には、フランジ１１部分を天井に固定するための挿通穴が１２が形成されている。箱体３の側面には、配線引出孔１３が形成されており、使用しない時には、ゴムキャップなどで閉じておくようにしてもよい。   A flange 11 is provided on the upper side of the box 3. In the flange 11, an insertion hole 12 for fixing the flange 11 portion to the ceiling is formed. A wiring lead-out hole 13 is formed on the side surface of the box 3 and may be closed with a rubber cap or the like when not in use.

次に、図３を用いて火災感知器について説明する。２０は火災感知器である。
火災感知器２０は、放射線区域などに設置され、鉛やポリエチレンなどの放射線遮蔽部材によって、中心にある図示しない火災感知器本体を覆ってある。このため、通常の火災感知器よりも、大型で重量が重くなっている（例えば数ｋｇ）。なお、通常の火災感知器に本発明を適用するようにしてもよい。 Next, the fire detector will be described with reference to FIG. 20 is a fire detector.
The fire detector 20 is installed in a radiation area or the like, and covers a fire detector main body (not shown) in the center by a radiation shielding member such as lead or polyethylene. For this reason, it is larger and heavier than a normal fire detector (for example, several kg). In addition, you may make it apply this invention to a normal fire detector.

火災感知器２０の背面側（天井設置側）には、平面長方形の基台２２がねじなどにより取り付けられている、基台２２の両側には、断面Ｌ型で天井面側へ折り曲げられた、取付用のアングル部２４が形成されており、このアングル部２４を、レール部材９にスライドさせて火災感知器２０が取付具１へ取り付けられる。アングル部２４の両端側には、固定用の固定穴２６が、また２つの固定穴２６の真ん中には、仮止め用の仮止め穴２７が一つ形成されている。２つの固定穴２６の間隔は、取付具１のレール部材９の両端に設けた取付穴１０の間隔と等しくなっている。   A flat rectangular base 22 is attached to the back side (ceiling installation side) of the fire detector 20 with screws or the like. Both sides of the base 22 are bent to the ceiling surface side with an L-shaped cross section. An angle portion 24 for attachment is formed, and the fire detector 20 is attached to the fixture 1 by sliding the angle portion 24 onto the rail member 9. A fixing hole 26 for fixing is formed on both ends of the angle portion 24, and one temporary fixing hole 27 for temporary fixing is formed in the middle of the two fixing holes 26. The interval between the two fixing holes 26 is equal to the interval between the mounting holes 10 provided at both ends of the rail member 9 of the fixture 1.

基台２２は火災感知器２０の直径よりも大きく、アングル部２４の部分が、火災感知器２０の周縁部からはみ出すような大きさになっている。またアングル部２４の長さは、取付具１にあるレール部材９の長さよりも長く形成されている。   The base 22 is larger than the diameter of the fire detector 20, and the angle portion 24 is sized so as to protrude from the peripheral edge of the fire detector 20. Further, the length of the angle portion 24 is formed longer than the length of the rail member 9 in the fixture 1.

続いて、火災感知器２０を天井に設置された取付具１に固定する場合について説明する。図４は取り付ける前段階の状態を示した図面、図５は火災感知器２０を取付具１へ装着した状態を示す図面で、図４，図５はそれぞれ９０度ずれた方向から見た状態を示している。なお、図４は、挿通穴１２，レール部材９の横に設けられた２つの取付穴及び開口部５を通る断面である。また説明の便宜上、火災感知器２０のアングル部２４の一部を断面で示してある。   Then, the case where the fire detector 20 is fixed to the fixture 1 installed on the ceiling is demonstrated. FIG. 4 is a view showing a state before attachment, FIG. 5 is a view showing a state where the fire detector 20 is mounted on the fixture 1, and FIGS. 4 and 5 are views seen from directions shifted by 90 degrees. Show. FIG. 4 is a cross section passing through the insertion hole 12 and the two attachment holes and the opening 5 provided on the side of the rail member 9. For convenience of explanation, a part of the angle portion 24 of the fire detector 20 is shown in cross section.

火災感知器２０の取付けに先立って、取付具１は予め、天井Ｔへ固定されている。即ち、取付具１の底板７を下側に位置させた状態で、フランジ１１の挿通穴１２にボルトなどを通して、天井Ｔへ取付具１を固定しておく。そして、火災感知器２０を持って、アングル部２４の高さを、取付具１のレール部材９の高さに合わせる。高さが一致したら、火災感知器２０をスライドさせて、底板７とレール部材９との隙間にアングル部２４を通して、火災感知器２０を押し込む（図４の左側へ移動させる）。この取付作業の際、一度、アングル部２４がレール部材９にのれば、火災感知器２０の重量はレール部材９側へうつっていき、また作業者は火災感知器２０を前方に押し込むだけなので、重量が重くても、容易に火災感知器２０を取付具１へ取り付けることができる。   Prior to the installation of the fire detector 20, the fixture 1 is fixed to the ceiling T in advance. That is, the fixture 1 is fixed to the ceiling T by passing a bolt or the like through the insertion hole 12 of the flange 11 with the bottom plate 7 of the fixture 1 positioned on the lower side. Then, holding the fire detector 20, the height of the angle portion 24 is adjusted to the height of the rail member 9 of the fixture 1. When the heights match, the fire detector 20 is slid, and the fire detector 20 is pushed through the angle portion 24 into the gap between the bottom plate 7 and the rail member 9 (moved to the left in FIG. 4). At the time of this mounting operation, once the angle portion 24 is placed on the rail member 9, the weight of the fire detector 20 moves toward the rail member 9, and the operator only pushes the fire detector 20 forward. Even if the weight is heavy, the fire detector 20 can be easily attached to the fixture 1.

火災感知器２０の結線作業を行うにあたって、火災感知器２０は、レール部材９の終端まで押し込まず、アングル部２４の仮止め穴２７が手前側の取付穴１０の位置と重なったら、その位置で、２つの穴にボルトをねじ込み火災感知器２０を取付具１へ仮止めする。この位置では、アングル部２４のほぼ半分がレール部材９上にのっかているので、配線作業をするにあたって、火災感知器２０がぐらついたりはしない。   When performing the wiring work of the fire detector 20, the fire detector 20 does not push into the end of the rail member 9, and the temporary fixing hole 27 of the angle portion 24 overlaps with the position of the mounting hole 10 on the near side. Screw the bolts into the two holes and temporarily fix the fire detector 20 to the fixture 1. In this position, since almost half of the angle portion 24 is on the rail member 9, the fire detector 20 does not wobble when performing wiring work.

火災感知器２０の配線は、底板７の開口部５を通して、天井Ｔ側からの配線と結線する。また天井下面に直に信号線を這わす場合には、配線束を開口部５から箱体３内に押し込み、それから箱板３の側面のキャップを外して、配線引出孔１３から配線を引き出して、天井下面に信号線を這わせるようにする。   The wiring of the fire detector 20 is connected to the wiring from the ceiling T side through the opening 5 of the bottom plate 7. In addition, when the signal line is routed directly to the lower surface of the ceiling, the wiring bundle is pushed into the box 3 from the opening 5, and then the cap on the side surface of the box plate 3 is removed, and the wiring is drawn out from the wiring drawing hole 13. , Make the signal line on the bottom of the ceiling.

火災感知器２０の結線作業が終わったら、仮止めしていたボルトを外し、アングル部２４をそのままレール部材９にスライドさせて押し込む。そしてアングル部２４の２つの固定穴２６と、取付具１の２つの取付穴１０の位置が一致したら、そこにボルトをねじ込んで、底板７の裏側にあるナットにボルトを固定する。こうして火災感知器２０は取付具１によって天井Ｔに固定される。   When the connection work of the fire detector 20 is completed, the temporarily fixed bolt is removed, and the angle portion 24 is slid and pushed into the rail member 9 as it is. Then, when the positions of the two fixing holes 26 of the angle portion 24 and the two mounting holes 10 of the fixture 1 coincide with each other, the bolts are screwed therein to fix the bolts to the nuts on the back side of the bottom plate 7. In this way, the fire detector 20 is fixed to the ceiling T by the fixture 1.
