Description

本発明は、例えばエレベータシャフト内に火災報知器を設置するための、火災報知器取付具に関する。   The present invention relates to a fire alarm fitting for installing a fire alarm in an elevator shaft, for example.

図10、図11に、従来の火災報知器取付具の一例を示す。図10は、この従来型火災報知器取付具の横面図、図11は、その正面図である。図12は、本願出願人が先に発明した、従来型火災報知器取付具に多少改良を加えた改良型の従来火災報知器取付具の横面図を、その設置方法とともに示したものである。   10 and 11 show an example of a conventional fire alarm fitting. FIG. 10 is a side view of the conventional fire alarm fitting, and FIG. 11 is a front view thereof. FIG. 12 shows a lateral view of an improved conventional fire alarm mounting device, which was previously invented by the applicant of the present application, with some improvements to the conventional fire alarm mounting device, together with its installation method. .

我国消防法では、エレベータ50が上下動するエレベータシャフト内52において、シャフト内天井部54から所定の位置、例えば、シャフト内天井部54から500mm以内の下方及び壁面より600mm以上の位置(後述する図5、図6によく示されている)に、火災報知器10を設置しなければならない旨定められている。このような位置は、通常、地面から相当の高さを有するため、エレベータシャフト内52へのアクセスは、一般に、シャフト内壁55の一部を貫通した状態で設けた横穴56から行われる。尚、横穴56の寸法は、例えば、約300mm×300mm×300mmとなっている。   According to the Fire Service Act of Japan, in the elevator shaft 52 in which the elevator 50 moves up and down, a predetermined position from the ceiling part 54 in the shaft, for example, a position within 500 mm from the ceiling part 54 in the shaft and a position 600 mm or more from the wall (described later) 5, which is well illustrated in FIG. 6, stipulates that the fire alarm 10 must be installed. Since such a position usually has a considerable height from the ground, the access to the elevator shaft 52 is generally made through a lateral hole 56 provided in a state of penetrating a part of the shaft inner wall 55. In addition, the dimension of the horizontal hole 56 is about 300 mm x 300 mm x 300 mm, for example.

この横穴56は、ビルの構造上、梁59の下側に設けられることが多い。この結果、横穴56の高さ位置は、消防法で定められたシャフト内天井部54から500mmよりもかなり下になってしまう。したがって、横穴56の高さ位置は、消防法で定める高さ位置に火災報知器10を設置しようとする際に大きな障害となっている。   The horizontal hole 56 is often provided on the lower side of the beam 59 due to the structure of the building. As a result, the height position of the horizontal hole 56 is considerably lower than 500 mm from the ceiling part 54 in the shaft defined by the Fire Service Law. Therefore, the height position of the horizontal hole 56 is a major obstacle when attempting to install the fire alarm 10 at a height position determined by the Fire Service Law.

例えば、図10、図11に示した従来型の火災報知器取付具5では、この横穴56の内壁に固定した筒状枠体20に固定されて横穴56を閉じるような鉄板58の位置、更に言えば、この鉄板58から垂直方向に延伸され、且つ、筒状枠体20を貫通させた、延伸部60の下側に、火災報知器10を固定するものとなっている。この鉄板58は、例えば、筒状枠体20のネジ穴66を利用して、筒状枠体20にネジ67で固定することができる。明らかなように、この従来型の火災報知器取付具5では、火災報知器10は、消防法で定められた高さ位置とは大きくかけ離れた、シャフト内天井部54よりもかなり下側に設置されることになってしまう。これでは消防法に定める規準を満足することができない。   For example, in the conventional fire alarm fitting 5 shown in FIGS. 10 and 11, the position of the iron plate 58 that is fixed to the cylindrical frame 20 fixed to the inner wall of the horizontal hole 56 and closes the horizontal hole 56, If it says, the fire alarm 10 will be fixed to the lower side of the extending | stretching part 60 extended | stretched from this iron plate 58 to the orthogonal | vertical direction, and let the cylindrical frame 20 penetrate. The iron plate 58 can be fixed to the cylindrical frame 20 with screws 67 using, for example, the screw holes 66 of the cylindrical frame 20. As is apparent, in this conventional fire alarm attachment 5, the fire alarm 10 is installed at a position considerably below the ceiling portion 54 in the shaft, which is far from the height position determined by the Fire Service Act. Will be done. This does not satisfy the standards set forth in the Fire Service Law.

このような従来技術における問題点を解決するため、本願出願人は、火災報知器取付具に曲がりを設けた図12に示すような火災報知器取付具7を先に発明した。この火災報知器取付具7は、曲がり棒72の先端部に火災報知器10を固定した状態でそれを横倒しにし、先端側を横穴56を通じてエレベータシャフト内52に挿入し、更に、横穴56の深くに挿入すると同時に、その先端側を垂直方向に徐々に起き上がらせ、最終的に、その中間部に設けた水平部分74を横穴56の天井部62に固定する、といった方法で取り付けられる。明らかなように、この火災報知器取付具7によって設置される火災報知器10は、横穴56の天井部62よりも高く、したがって、シャフト内天井部54により接近させた状態で設置されることになる。しかしながら、この従来構成では、シャフト内天井部54から火災報知器10までの距離が曲がり棒72の寸法によって予め定められてしまうため、また、曲がり棒の曲がりの大きさ等を横穴56の大きさに合わせて予め定めておかなければならないため、汎用性に欠けるという大きな問題がある。   In order to solve such a problem in the prior art, the applicant of the present application first invented the fire alarm attachment 7 as shown in FIG. 12 in which the fire alarm attachment is bent. The fire alarm attachment 7 lies in a state where the fire alarm 10 is fixed to the distal end portion of the bending rod 72, and the distal end side is inserted into the elevator shaft 52 through the lateral hole 56. At the same time, the tip side is gradually raised in the vertical direction, and finally the horizontal portion 74 provided at the intermediate portion is fixed to the ceiling portion 62 of the lateral hole 56. As is apparent, the fire alarm 10 installed by the fire alarm attachment 7 is higher than the ceiling portion 62 of the side hole 56, and is therefore installed in a state of being closer to the ceiling portion 54 in the shaft. Become. However, in this conventional configuration, since the distance from the shaft inner ceiling 54 to the fire alarm 10 is determined in advance by the dimensions of the bending rod 72, the bending amount of the bending rod and the like are the size of the horizontal hole 56. Therefore, there is a big problem that it lacks versatility.

本発明は新たな分野を開拓するものであるため先行技術文献は特に存在しない。   Since the present invention opens up new fields, there is no prior art document.

本発明は上の従来技術における問題点を解決するためになされたものであり、簡易な構造を有する火災報知器取付具を用いて、火災報知器をエレベータシャフト内の最適な位置に設置することができる火災報知器取付具を提供するものである。   The present invention has been made to solve the above problems in the prior art, and uses a fire alarm fitting having a simple structure to install a fire alarm at an optimum position in an elevator shaft.

本発明によれば、簡易な構造を有する火災報知器取付具を用いて、火災報知器をエレベータシャフト内の最適な位置に設置することができる。   ADVANTAGE OF THE INVENTION According to this invention, a fire alarm can be installed in the optimal position in an elevator shaft using the fire alarm attachment tool which has a simple structure.

図1乃至図4に、本発明の第一の実施形態による火災報知器取付具を示す。図1は、この火災報知器取付具の横面図、図2は、その正面図、図3は、その上面図である。図4は、この火災報知器取付具を設置する工程を示す図である。図1乃至図4において、図10乃至図12と同様の部材には同様の番号を付している。   1 to 4 show a fire alarm fitting according to a first embodiment of the present invention. 1 is a side view of the fire alarm fitting, FIG. 2 is a front view thereof, and FIG. 3 is a top view thereof. FIG. 4 is a diagram showing a process of installing this fire alarm attachment. 1 to 4, the same members as those in FIGS. 10 to 12 are denoted by the same reference numerals.

図1乃至3によく示されるように、本発明の火災報知器取付具1は、火災報知器10を取り付けることができる延伸部12と、この延伸部12が固定される真っ直ぐな棒状の環状シャフト(棒状部材)14と、このシャフト14を自身の内部に貫通させスライド可能に保持固定することができる円筒状の加工パイプ(保持部材)16と、加工パイプ16に連結され火災報知器取付具1を所定の箇所に固定するための固定部18から成る。   As well shown in FIGS. 1 to 3, the fire alarm attachment 1 of the present invention includes an extension part 12 to which the fire alarm 10 can be attached, and a straight rod-like annular shaft to which the extension part 12 is fixed. (Bar-shaped member) 14, a cylindrical processing pipe (holding member) 16 that can be slidably held and passed through the shaft 14, and a fire alarm fitting 1 connected to the processing pipe 16. It consists of the fixing | fixed part 18 for fixing to a predetermined location.

火災報知器10は、延伸部12と火災報知器10のそれぞれの対応部分に設けたネジ穴22にボルト(図示されていない)を通す等して、シャフト14の先端側、更に言えば、その先端に設けた延伸部12に固定される。火災報知器10を固定したシャフト14は、その後、加工パイプ16に、その長手方向からスライド可能な状態で挿入される。加工パイプ16の側面には、貫通させたネジ穴28が設けられており、このネジ穴28を通じた蝶ネジ30を利用して、シャフト14を圧力調整可能に加工パイプ内部24の所定位置に位置決めし、固定することができる。尚、シャフト14は、この蝶ネジ30によって固定される以前においては、加工パイプ内部24で、図示矢印ア方向(図1参照)にて、自由にスライドさせることができ、また、加工パイプ16から自由に抜き差しすることができるものとする。   The fire alarm 10 is configured such that a bolt (not shown) is passed through the screw holes 22 provided in the corresponding portions of the extending portion 12 and the fire alarm 10 to provide a distal end side of the shaft 14. It is fixed to the extending portion 12 provided at the tip. Thereafter, the shaft 14 to which the fire alarm 10 is fixed is inserted into the processing pipe 16 in a slidable state from the longitudinal direction. A threaded hole 28 is provided in the side surface of the processed pipe 16, and the shaft 14 is positioned at a predetermined position in the processed pipe interior 24 so that the pressure can be adjusted by using a thumbscrew 30 through the threaded hole 28. And can be fixed. Before the shaft 14 is fixed by the thumbscrew 30, the shaft 14 can be freely slid in the direction of the arrow A (see FIG. 1) inside the processing pipe 24, and from the processing pipe 16. It can be inserted and removed freely.

加工パイプ16は、固定部18を利用して、シャフト内壁55の横穴56の一部、例えば、横穴56の底面35に、固定され得る。固定部18は、その中心付近にネジ穴32を有し、このネジ穴32に対応して、横穴56の底面にはネジ穴39が設けられている。ネジ穴32、39を貫通させた状態で固定用ナット34を取り付けることにより、固定部18と、更に、この固定部18に固定された加工パイプ16を、横穴56に固定することができる。加工パイプ16をエレベータシャフト内52に設置したとき、加工パイプ16は、垂直方向に、つまり、エレベータ移動方向に沿って設置される。この結果、シャフト14も、垂直方向に設置されることになる。   The processing pipe 16 can be fixed to a part of the lateral hole 56 of the shaft inner wall 55, for example, the bottom surface 35 of the lateral hole 56 using the fixing portion 18. The fixing portion 18 has a screw hole 32 near the center thereof, and a screw hole 39 is provided on the bottom surface of the lateral hole 56 corresponding to the screw hole 32. By attaching the fixing nut 34 in a state where the screw holes 32 and 39 are penetrated, the fixing portion 18 and the processed pipe 16 fixed to the fixing portion 18 can be fixed to the lateral hole 56. When the processing pipe 16 is installed in the elevator shaft 52, the processing pipe 16 is installed in the vertical direction, that is, along the elevator movement direction. As a result, the shaft 14 is also installed in the vertical direction.

次に、図4を参照して、本発明の火災報知器取付具の設置方法の一例を説明する。先ず、エレベータシャフト内52に加工パイプ16を突出させた状態として、加工パイプ16に連結された固定部18を横穴56の底面35に固定する。次いで、火災報知器10を先端部に固定したシャフト14を横倒しにし、その先端側から略水平方向にてエレベータシャフト内52へ横穴56から挿入し、その後、垂直状態とする。その後、垂直方向に設置された加工パイプ16の加工パイプ16の上部からシャフト14をそこに貫通させるように挿入し、図示矢印イに示すように上下にスライドさせる。シャフト14を、所望の高さ位置とした後、蝶ネジ30を用いてシャフト14を加工パイプ16に固定する。これにより、火災報知器10をシャフト内天井部54から所望の位置に、例えば、シャフト内天井部54から500mm以内に容易に設置することができる。   Next, with reference to FIG. 4, an example of the installation method of the fire alarm attachment of this invention is demonstrated. First, the fixed portion 18 connected to the processed pipe 16 is fixed to the bottom surface 35 of the horizontal hole 56 with the processed pipe 16 protruding from the elevator shaft 52. Next, the shaft 14 with the fire alarm 10 fixed to the tip is laid sideways, and is inserted from the side hole 56 into the elevator shaft 52 in the substantially horizontal direction from the tip side, and then brought into a vertical state. Thereafter, the shaft 14 is inserted from the upper part of the processing pipe 16 of the processing pipe 16 installed in the vertical direction so as to penetrate therethrough, and is slid up and down as shown by the arrow A in the drawing. After setting the shaft 14 to a desired height position, the shaft 14 is fixed to the processing pipe 16 using a thumbscrew 30. Thereby, the fire alarm 10 can be easily installed at a desired position from the shaft inner ceiling portion 54, for example, within 500 mm from the shaft inner ceiling portion 54.

図5乃至図9に、本発明の第二の実施形態による火災報知器取付具を示す。ここで、図5、図6はそれぞれ、本発明の第一の実施形態の図1、図2に対応する。尚、図5、図6では、理解容易のため、シャフト内天井部54やシャフト内壁55も示している。図7は、本実施形態で特に用いた高さ調節機構を示す図であり、図8は、この高さ調節機構を用いた火災報知器取付具の設置方法の一例を示す図である。更に、図9は、火災報知器の点検時における火災報知器取付具の状態を示す図である。尚、図5乃至図9において、図1乃至図4と同様の部材には同様の番号を付している。   5 to 9 show a fire alarm attachment according to a second embodiment of the present invention. Here, FIGS. 5 and 6 correspond to FIGS. 1 and 2 of the first embodiment of the present invention, respectively. 5 and 6 also show the shaft inner ceiling 54 and the shaft inner wall 55 for easy understanding. FIG. 7 is a view showing a height adjustment mechanism particularly used in the present embodiment, and FIG. 8 is a view showing an example of a method for installing a fire alarm attachment using the height adjustment mechanism. Furthermore, FIG. 9 is a figure which shows the state of the fire alarm attachment tool at the time of inspection of a fire alarm. 5 to 9, the same members as those in FIGS. 1 to 4 are denoted by the same reference numerals.

第二の実施形態と第一の実施形態の主な相違は、この第二の実施形態では、第一の実施形態の構成に加え、更に、高さ調節機構と可動延伸機構が設けられている点にある。その他、例えば、この第2の実施形態では、可動延伸部12Aの先端に設けた円盤部88に火災報知器10を固定するようにしている点、また、この円盤部88に、火災報知器10を取り付けるためのネジ穴22に加えて、感知器用ケーブル穴90を設けている点等においても第一の実施形態と相違する(ただし、これらの相違は本質的なものではない)。   The main difference between the second embodiment and the first embodiment is that in the second embodiment, in addition to the configuration of the first embodiment, a height adjusting mechanism and a movable stretching mechanism are further provided. In the point. In addition, for example, in the second embodiment, the fire alarm 10 is fixed to the disk portion 88 provided at the tip of the movable extending portion 12A, and the fire alarm 10 is attached to the disk portion 88. In addition to the screw hole 22 for attaching the sensor cable, a sensor cable hole 90 is provided, and the like is different from the first embodiment (however, these differences are not essential).

高さ調節機構は、環状シャフト14Aの表面に、約90度(それより若干小さい)の角度範囲で対向配置された外方に突出するねじ切り部84、84’と、これに対応して加工パイプ16Aの内面に約90度(それより若干小さい)の角度範囲で対向配置された内方(中心側に向かって)に突出するねじ切り部86、86’の対から成る。   The height adjusting mechanism includes outwardly projecting threaded portions 84 and 84 ′ that are disposed on the surface of the annular shaft 14 </ b> A so as to face each other at an angle range of about 90 degrees (slightly smaller), and a corresponding processing pipe. It consists of a pair of threaded portions 86, 86 'projecting inwardly (toward the center) facing each other at an angle range of about 90 degrees (slightly smaller) on the inner surface of 16A.

ここで、図8のa)、b)は、この高さ調節機構を用いて高さ調整を行っている最中の状態を示す図であり、a)は、装置の一部部分概略拡大斜視図を、b)は、a)のA−A線概略断面図を、それぞれ示す。一方、図8のc)、d)は、この高さ調節機構を用いて高さ調節を行った後の状態、つまり、高さが決定された状態、を示す図であって、c)は、装置の一部部分概略拡大斜視図を、d)は、c)のB−B線概略断面図を、それぞれ示す。   Here, a) and b) of FIG. 8 are views showing a state during height adjustment using this height adjustment mechanism, and a) is a partially enlarged schematic perspective view of a part of the apparatus. FIG. 4B is a schematic sectional view taken along line AA of a). On the other hand, c) and d) in FIG. 8 are views showing a state after the height adjustment using this height adjustment mechanism, that is, a state in which the height is determined. FIG. 2 is a partially enlarged schematic perspective view of a part of the apparatus, and FIG.

図8のa)、b)に示すように、高さ調節を行っている間は、ねじ切り部84、84’とねじ切り部86、86’は、約90度の角度ずつ互いにずらした状態、つまり、ネジの噛み合わせが解かれた状態とされている。このとき、シャフト14Aは加工パイプ16Aに対して図示矢印ウ方向にて自由にスライドさせることができる。一方、図8のc)、d)に示すように、高さ調節を行った後は、ねじ切り部84、84’とねじ切り部86、86’は、それぞれ、互いに噛み合った状態とされる。この結果、シャフト14Aは加工パイプ16Aの所定位置に容易に位置決めされ、その高さが固定される。   As shown in FIGS. 8A and 8B, during the height adjustment, the threaded portions 84 and 84 ′ and the threaded portions 86 and 86 ′ are shifted from each other by an angle of about 90 degrees, that is, The screw is in a disengaged state. At this time, the shaft 14A can be freely slid in the direction indicated by the arrow C with respect to the processing pipe 16A. On the other hand, as shown in c) and d) of FIG. 8, after the height adjustment, the threaded portions 84 and 84 'and the threaded portions 86 and 86' are in mesh with each other. As a result, the shaft 14A is easily positioned at a predetermined position of the processing pipe 16A, and its height is fixed.

可動延伸機構は、可動延伸部12Aを、シャフト14Aに設けたスライド用の水平穴80にスライド可能な状態で貫通させることによって形成される。この可動延伸部12Aは、シャフト14Aの穴80を貫通した状態で、シャフト12Aの頂部に設けた蝶ネジ82によって容易にそこに固定され得る。この蝶ネジ82は、必要に応じて、自由に緩めたり締めたりすることができる。可動延伸部12Aを穴80内でスライドさせることにより、可動延伸部12Aを、シャフト14Aに対して垂直方向に、また、シャフト14Aに関して自由に移動させることができる、換言すれば、シャフト14Aからの突出長さを調節することができる。後述するように、このシャフト14Aからの突出長さの調節は、図9を参照して以下に説明する火災報知器の点検時に重要な役割を果たす。   The movable stretching mechanism is formed by penetrating the movable stretching portion 12A through a sliding horizontal hole 80 provided in the shaft 14A in a slidable state. The movable extending portion 12A can be easily fixed thereto by a thumbscrew 82 provided on the top of the shaft 12A in a state of passing through the hole 80 of the shaft 14A. The thumbscrew 82 can be freely loosened or tightened as required. By sliding the movable extension portion 12A within the hole 80, the movable extension portion 12A can be moved freely in the direction perpendicular to the shaft 14A and with respect to the shaft 14A, in other words, from the shaft 14A. The protruding length can be adjusted. As will be described later, the adjustment of the projecting length from the shaft 14A plays an important role in the inspection of the fire alarm described below with reference to FIG.

最後に、図5、図8等に加えて、図9をも参照して、第二の実施形態による火災報知機取付具における火災報知器の点検方法を説明する。火災報知器10を点検するには、エレベータシャフト52内の火災報知器10を横穴56を通じてエレベータシャフト52の外部に取り出す必要がある、言い換えれば、図5や図8のc)、d)に示す状態にある火災報知器取付具1(火災報知器10)を、図9に示す状態にする必要がある。このとき、上に説明した高さ調節機構や可動延伸機構を利用できる。   Finally, with reference to FIG. 9 in addition to FIG. 5, FIG. 8 etc., the inspection method of the fire alarm in the fire alarm attachment by 2nd embodiment is demonstrated. In order to check the fire alarm 10, it is necessary to take out the fire alarm 10 in the elevator shaft 52 to the outside of the elevator shaft 52 through the side hole 56, in other words, as shown in FIGS. 5 and 8 c) and d). The fire alarm attachment 1 (fire alarm 10) in the state needs to be in the state shown in FIG. At this time, the height adjusting mechanism and the movable stretching mechanism described above can be used.

先ず、蝶ネジ30A、30A’を緩めて、図5や図8のc)、d)に示す状態にあるシャフト14Aを、加工パイプ16Aに対して約90度、図示矢印エ方向(図8参照)に回転させることにより、図8のa)、b)に示す状態とし、つまり、可動状態とし、火災報知器10やこれを固定した可動延伸部12A(円盤部88)を、横穴56の位置まで下げる(図示矢印ウ方向)。その後、可動延伸機構を利用して、可動延伸部12Aを図示矢印オ方向にて水平方向にスライドさせた後、シャフト14Aを加工パイプ16Aに対して更に約90度、図示矢印エ方向(図8参照)に回転させて、火災報知器10を横穴56の略正面に位置付ける。尚、もし可動延伸部12Aを(図示矢印オ方向に)スライドさせずに、シャフト14Aを加工パイプ16Aに対して回転させた場合には、可動延伸部12Aがシャフト内壁55に衝突してしまい、そのような回転を行わせることはできない。その後、火災報知器10を横穴46の略正面位置に位置付けた後、再び水平延伸機構を利用して、上記方向(図示矢印オ方向)とは逆方向(図示矢印カ方向)に可動延伸部12Aを水平方向にスライドさせることにより、火災報知器10をエレベータシャフト52の外部に取り出すことができる、つまり、図9に示す状態にすることができる。   First, the thumbscrews 30A and 30A ′ are loosened, and the shaft 14A in the state shown in FIGS. 5 and 8 c) and d) is about 90 degrees with respect to the processed pipe 16A in the direction indicated by the arrow D (see FIG. 8). 8) to the state shown in a) and b) of FIG. 8, that is, in a movable state, the fire alarm 10 and the movable extending portion 12A (disk portion 88) to which the fire alarm 10 is fixed are positioned in the horizontal hole 56. (Down arrow direction). Thereafter, using the movable stretching mechanism, the movable stretching portion 12A is slid in the horizontal direction in the direction of the arrow O, and then the shaft 14A is further about 90 degrees with respect to the processing pipe 16A by the direction of the arrow D (FIG. The fire alarm 10 is positioned substantially in front of the lateral hole 56. If the shaft 14A is rotated with respect to the processing pipe 16A without sliding the movable extending portion 12A (in the direction of arrow O in the figure), the movable extending portion 12A collides with the shaft inner wall 55, Such rotation cannot be performed. Then, after positioning the fire alarm 10 at a substantially front position of the horizontal hole 46, the movable extending portion 12A is used in the direction opposite to the above-mentioned direction (the direction indicated by the arrow O) using the horizontal extending mechanism again. Can be taken out of the elevator shaft 52, that is, the state shown in FIG. 9 can be obtained.

ビルのエレベータシャフト内における火災報知器の取付に幅広く利用することができる。   It can be widely used to install fire alarms in building elevator shafts.
