It is in.

この発明に係る配設体支持具は、前記目的を達成するために、次の構成からなる。すなわち、
請求項１に記載の発明に係る配設体支持具は、デッキプレートの下方に突出形成された下方が幅広で上方が幅狭となる補強部に取り付けられて、配設体を支持する、配設体支持具である。この配設体支持具は、前記補強部に取り付けられる取付部と、前記配設体を支持する支持部とを備える。ここで、前記取付部は、上方に開口する枠状に形成されて、その開口を形成する両側が、前記補強部を保持する保持部となる。そして、前記取付部は、前記保持部をその対向方向の互いに離間する向きに変位させるような、曲げ方向の剛性が大で、前記保持部をその対向方向に直交する前後方向の互いに逆となる向きに変位させるような、ねじり方向の剛性が小となるよう形成されて、そのねじり方向に弾性変形可能である。そこで、前記取付部を前記ねじり方向に弾性変形させることで、前記保持部の互いの間隔を広げて、前記取付部を前記補強部の下方から取付可能となる。 In order to achieve the object, the arrangement body support according to the present invention has the following configuration. That is,
According to the first aspect of the present invention, there is provided an arrangement body support that is attached to a reinforcing portion that is formed so as to project downward from the deck plate and has a wide lower portion and a narrow upper portion, and supports the arrangement body. It is a structure support tool. This arrangement | positioning body support tool is provided with the attaching part attached to the said reinforcement part, and the support part which supports the said arrangement | positioning body. Here, the attachment portion is formed in a frame shape opening upward, and both sides forming the opening serve as holding portions for holding the reinforcing portion. The mounting portion has a large rigidity in the bending direction that displaces the holding portion in a direction away from each other in the opposing direction, and the holding portions are opposite to each other in the front-rear direction perpendicular to the opposing direction. It is formed so as to have a small rigidity in the torsional direction that is displaced in the direction, and can be elastically deformed in the torsional direction. Therefore, by elastically deforming the mounting portion in the torsional direction, the interval between the holding portions can be widened and the mounting portion can be mounted from below the reinforcing portion.

この配設体支持具によると、その取付部が、デッキプレートの下方に突出する補強部に取り付けられ、支持部が、配設体を支持することで、配設体は、この配設体支持具を介して、デッキプレートの補強部に支持される。ここで、補強部への取り付けにあたっては、取付部を、その保持部をその対向方向に直交する前後方向の互いに逆となる向きに変位させるような、ねじり方向に弾性変形させることで、保持部の互いの間隔を広げる。そして、この広がった保持部の先端部分の渡り方向がデッキプレートの補強部の幅方向を向くように取付部を鉛直軸回りに回動し、その回動した向きのまま、広がった保持部の間にデッキプレートの補強部が進入するように、取付部を補強部の下方から持ち上げる。その後、取付部のねじりをその弾性により戻すとともに、前記鉛直軸回りの回動を戻すことで、両保持部でデッキプレートの補強部を保持する。こうして、取付部がデッキプレートの補強部に取り付けられるが、取付部は、保持部をその対向方向の互いに離間する向きに変位させるような、曲げ方向の剛性が大となっているため、保持部は、その対向方向に安易には変位することがなく、取付部は、デッキプレートの補強部にしっかりと取り付けられる。 According to this arrangement body support tool, the attachment portion is attached to the reinforcing portion protruding below the deck plate, and the support section supports the arrangement body, so that the arrangement body is supported by this arrangement body.

Increase the distance between each other. Then, the mounting portion is rotated about the vertical axis so that the crossing direction of the distal end portion of the extended holding portion faces the width direction of the reinforcing portion of the deck plate, and the extended holding portion remains in the rotated direction. The attachment portion is lifted from below the reinforcement portion so that the reinforcement portion of the deck plate enters between them. Thereafter, the torsion of the mounting portion is returned by its elasticity and the rotation around the vertical axis is returned to hold the reinforcing portion of the deck plate by both holding portions. In this way, the attachment portion is attached to the reinforcing portion of the deck plate, but the attachment portion has a large rigidity in the bending direction that displaces the holding portion in the facing direction away from each other. Is not easily displaced in the opposite direction, and the attachment portion is firmly attached to the reinforcement portion of the deck plate.

次に、以上の構成からなる配設体支持具４の作用効果について説明する。この配設体支持具４によると、その取付部５が、デッキプレート２の下方に突出する補強部２ａに取り付けられ、支持部６が、配設体３を支持することで、配設体３は、この配設体支持具４を介して、デッキプレート２の補強部２ａに支持される。ここで、補強部２ａへの取り付けにあたっては、図５に示すように、取付部５を、その保持部５ｂ、５ｂをその対向方向に直交する前後方向の互いに逆となる向きに変位させるような、ねじり方向に弾性変形させることで、保持部５ｂ、５ｂの互いの間隔を広げる。そして、この広がった保持部５ｂ、５ｂの先端部分の渡り方向がデッキプレートの補強部の幅方向を向くように取付部５（配設体支持具４）を鉛直軸回りに回動し、その回動した向きのまま、広がった保持部５ｂ、５ｂの間にデッキプレート２の補強部２ａが進入するように、取付部５（配設体支持具４）を補強部２ａの下方から持ち上げる。その後、取付部５のねじりをその弾性により戻すとともに、前記鉛直軸回りの回動を戻すことで、両保持部５ｂ、５ｂでデッキプレート２の補強部２ａを保持する（図６参照）。こうして、取付部５がデッキプレート２の補強部２ａに取り付けられるが、取付部５は、保持部５ｂ、５ｂをその対向方向の互いに離間する向きに変位させるような、曲げ方向の剛性が大となっている。このため、保持部５ｂ、５ｂは、その対向方向に安易には変位することがなく、取付部５は、デッキプレート２の補強部２ａにしっかりと取り付けられる。こうして、この配設体支持具４によれば、取付部５を、ねじり方向の弾性を利用してデッキプレート２の補強部２ａに取り付けるため、配設体支持具４は、構造が簡単となり、かつ、この配設体支持具４をデッキプレート２の補強部２ａに容易に取り付けることができる。 Next, the effect of the arrangement | positioning body support tool 4 which consists of the above structure is demonstrated. According to the arrangement body support 4, the attachment portion 5 is attached to the reinforcing portion 2 a protruding downward from the deck plate 2, and the support portion 6 supports the arrangement body 3, whereby the arrangement body 3. Is supported by the reinforcing portion 2 a of the deck plate 2 through the arrangement body support 4. Here, in attaching to the reinforcing portion 2a, as shown in FIG. 5, the attaching portion 5 is displaced in the opposite directions in the front-rear direction perpendicular to the opposing direction of the holding portions 5b and 5b. The space between the holding portions 5b and 5b is increased by elastically deforming in the torsional direction. Then, the mounting portion 5 (arrangement body support 4) is rotated around the vertical axis so that the crossing direction of the extended end portions of the holding portions 5b and 5b faces the width direction of the reinforcing portion of the deck plate, The mounting part 5 (arrangement body support 4) is lifted from below the reinforcing part 2a so that the reinforcing part 2a of the deck plate 2 enters between the extended holding parts 5b and 5b in the rotated direction. Thereafter, the torsion of the mounting portion 5 is returned by its elasticity, and the rotation about the vertical axis is returned to hold the reinforcing portion 2a of the deck plate 2 by the holding portions 5b and 5b (see FIG. 6). In this way, the attachment portion 5 is attached to the reinforcing portion 2a of the deck plate 2, but the attachment portion 5 has a large bending direction rigidity so as to displace the holding portions 5b and 5b away from each other in the opposing direction. It has become. For this reason, the holding portions 5b and 5b are not easily displaced in the facing direction, and the attachment portion 5 is firmly attached to the reinforcement portion 2a of the deck plate 2. Thus, according to the arrangement body support 4, since the attachment portion 5 is attached to the reinforcing portion 2 a of the deck plate 2 using the elasticity in the torsion direction, the arrangement body support 4 has a simple structure, And this arrangement | positioning body support tool 4 can be easily attached to the reinforcement part 2a of the deck plate 2. FIG.

また、取付部５における下部片５ｅ（詳細には、第１板部５ｇ）には、孔５ｊがあけられており、この孔５ｊによって、前記ねじり方向の剛性を、より小さくすることができる。もっとも、この孔５ｊは、必要に応じて設けられるものであって、なくともよい。 Further, a hole 5j is formed in the lower piece 5e (specifically, the first plate part 5g) in the attachment portion 5, and the rigidity in the torsional direction can be further reduced by the hole 5j. But this hole 5j is provided as needed, and does not need to be.

また、配設体支持具４は、保持片５ｄ、５ｄにおける延設部５ｃ、５ｃどうしを連結する連結片７を備えている。これにより、取付部５をデッキプレート２の補強部２ａに取り付ける際には、連結片７の少なくとも一端側（図示実施の形態においては、連結片７の一端側）を延設部５ｃから外しておき、取付部５を補強部２ａに取り付けた後に、連結片７（図示実施の形態においては、連結片７の一端側）を延設部５ｃに取り付けるようにして、延設部５ｃ、５ｃどうしを連結する（図７、図８参照）。こうして、連結片７で延設部５ｃ、５ｃ（つまりは、保持片５ｄ、５ｄ）どうしを連結することで、保持部５ｂ、５ｂがその対向方向において互いに離間するのを抑制することができるとともに、保持部５ｂ、５ｂがその対向方向に直交する前後方向において互いに逆向きにずれるのを抑制することができる。これにより、保持部５ｂ、５ｂの互いの間隔が広がるのが抑えられ、取付部５を、デッキプレート２の補強部２ａに確実に取り付けることができる。さらに、配設体支持具４は、連結片７の他に補助連結片８を備えており、連結片７で延設部５ｃ、５ｃどうしを連結した後に、この補助連結片８で、第１孔５ｋを有する側の延設部５ｃと連結片７とを連結する（図９、図１０参照）。こうして、この補助連結片８を用いることで、連結片７による延設部５ｃ、５ｃ（つまりは、保持片５ｄ、５ｄ）どうしの連結を確実なものとすることができる。 Moreover, the arrangement | positioning body support 4 is provided with the connection piece 7 which connects the extension parts 5c and 5c in the holding pieces 5d and 5d. Thereby, when attaching the attachment part 5 to the reinforcement part 2a of the deck plate 2, at least one end side (in the illustrated embodiment, one end side of the connection piece 7) of the connecting piece 7 is removed from the extending part 5c. After attaching the attachment portion 5 to the reinforcing portion 2a, the extension portions 5c and 5c are connected to each other by attaching the connection piece 7 (one end side of the connection piece 7 in the illustrated embodiment) to the extension portion 5c. Are connected (see FIGS. 7 and 8). Thus, by connecting the extending portions 5c and 5c (that is, the holding pieces 5d and 5d) with the connecting piece 7, it is possible to suppress the holding portions 5b and 5b from being separated from each other in the facing direction. The holding portions 5b and 5b can be prevented from shifting in the opposite directions in the front-rear direction orthogonal to the facing direction. Thereby, it is suppressed that the space | interval of the holding | maintenance parts 5b and 5b spreads, and the attachment part 5 can be reliably attached to the reinforcement part 2a of the deck plate 2. FIG. Furthermore, the arrangement | positioning body support 4 is equipped with the auxiliary | assistant connection piece 8 other than the connection piece 7, and after connecting the extension parts 5c and 5c with the connection piece 7, it is 1st by this auxiliary | assistant connection piece 8. The extending portion 5c on the side having the hole 5k and the connecting piece 7 are connected (see FIGS. 9 and 10). Thus, by using this auxiliary connecting piece 8, the extended portions 5c and 5c (that is, the holding pieces 5d and 5d) by the connecting piece 7 can be reliably connected.

また、連結片７で延設部５ｃ、５ｃどうしを連結すると、連結片７（詳細には、当接部７ａ）がデッキプレート２における補強部２ａの下面に当接する。こうして、連結片７が補強部２ａの下面に当接することで、補強部２ａに対する取付部５の動きが抑えられ、この取付部５を補強部２ａに安定して取り付けることができる。 When the extending portions 5 c and 5 c are connected by the connecting piece 7, the connecting piece 7 (specifically, the contact portion 7 a) contacts the lower surface of the reinforcing portion 2 a in the deck plate 2. Thus, the connecting piece 7 abuts on the lower surface of the reinforcing portion 2a, so that the movement of the mounting portion 5 with respect to the reinforcing portion 2a is suppressed, and the mounting portion 5 can be stably attached to the reinforcing portion 2a.

また、連結片７における当接部７ａは、線条片７ｃからなる。このため、この線条片７ｃは、切断容易であり、この線条片７ｃを切断して取り除けば、連結片本体７ｂそのものが連結片として機能する。そこで、図１１に示すように、配設体支持具４を、サイズの大きい補強部２ａに取り付けることができ、この場合には、連結片本体７ｂの上面が当接部７ａとなる。 Moreover, the contact part 7a in the connection piece 7 consists of the strip piece 7c. For this reason, this line piece 7c is easy to cut | disconnect, and if this line piece 7c is cut | disconnected and removed, the connection piece main body 7b itself will function as a connection piece. Then, as shown in FIG. 11, the arrangement | positioning body support tool 4 can be attached to the reinforcement part 2a with a big size, and the upper surface of the connection piece main body 7b becomes the contact part 7a in this case.

また、配設体３を支持する支持部６は、取付部５を構成する下部片５ｅと延設部５ｃ、５ｃとで形成される。こうして、取付部５の一部が、支持部６を兼ねることで、配設体支持具４の構造を一層簡単にすることができる。 Moreover, the support part 6 which supports the arrangement | positioning body 3 is formed with the lower piece 5e and the extension parts 5c and 5c which comprise the attachment part 5. As shown in FIG. Thus, a part of the attachment portion 5 also serves as the support portion 6, whereby the structure of the arrangement body support tool 4 can be further simplified.

なお、本発明は、上述した実施の形態に限定されるわけではなく、その他種々の変更が可能である。例えば、デッキプレート２における補強部２ａは、上側ほど幅狭となるような三角形状をしているが、下方が幅広で上方が幅狭となっていればよく、逆Ｔ字形状とか（図１２参照）、Ｌ字形状等の形状をしていてもよい。ここで、図１２においては、配設体支持具４における保持部５ｂ、５ｂは、それらの先端部分５ｘ、５ｘが互いに対向する内側に曲がって形成されている。そして、これら保持部５ｂ、５ｂの先端部分５ｘ、５ｘが、デッキプレート２の補強部２ａの横に延びる幅広部２ｘの上面に載るようにして、保持部５ｂは、デッキプレート２の補強部２ａを保持する。 In addition, this invention is not necessarily limited to embodiment mentioned above, A various other change is possible. For example, the reinforcing portion 2a in the deck plate 2 has a triangular shape that becomes narrower toward the upper side, but it is sufficient that the lower portion is wide and the upper portion is narrow, such as an inverted T shape (FIG. 12). Reference), and may be L-shaped or the like. Here, in FIG. 12, the holding | maintenance parts 5b and 5b in the arrangement | positioning body support tool 4 are formed so that those front-end | tip parts 5x and 5x may bend inside. The front end portions 5x and 5x of the holding portions 5b and 5b are placed on the upper surface of the wide portion 2x extending laterally of the reinforcing portion 2a of the deck plate 2, so that the holding portion 5b is the reinforcing portion 2a of the deck plate 2. Hold.

また、配設体３は、配線・配管材に限られるものでなく、例えば、配線ボックス等のボックスとか、火災報知器等の機器であってもよい。また、支持部６は、配設体３の種類に応じた形状を有するのが好ましく、取付部５の一部で構成されなくとも、取付部５とは別の構成で形成されても構わない。また、このように、支持部６が取付部５とは別の構成で形成される場合には、延設部５ｃをなくして、保持部５ｂそのものが保持片５ｄとなってもよい。 Moreover, the arrangement | positioning body 3 is not restricted to wiring and piping material, For example, apparatuses, such as boxes, such as a wiring box, and a fire alarm. In addition, the support portion 6 preferably has a shape corresponding to the type of the arrangement body 3, and may not be formed of a part of the mounting portion 5 but may be formed of a configuration different from the mounting portion 5. . Further, when the support portion 6 is formed in a configuration different from that of the attachment portion 5 as described above, the extension portion 5c may be omitted and the holding portion 5b itself may be the holding piece 5d.

また、延設部５ｃ、５ｃどうしを連結する連結片７は、取付部５と一体に形成されて、その一端側が延設部５ｃに着脱可能に取り付けられるが、各端側が延設部５ｃに着脱可能に取り付けられるものであってもよい。すなわち、連結片７は、取付部５とは別体に形成されてもよい。また、同様にして、補助連結片８においても、取付部５とは別体に形成されても構わない。 Further, the connecting piece 7 for connecting the extending portions 5c and 5c is formed integrally with the attaching portion 5, and one end side thereof is detachably attached to the extending portion 5c, but each end side is attached to the extending portion 5c. It may be detachably attached. That is, the connecting piece 7 may be formed separately from the attachment portion 5. Similarly, the auxiliary connecting piece 8 may be formed separately from the attachment portion 5.

また、配設体支持具４における連結片７には、切除可能な線条片７ｃが設けられているが、この線条片７ｃは、始めからなくともよい。また、配設体支持具４は、この連結片７とか補助連結片８を備えなくともよい。 Moreover, although the strip 7c which can be excised is provided in the connection piece 7 in the arrangement body support tool 4, this strip piece 7c does not need to be from the beginning. Moreover, the arrangement | positioning body support 4 does not need to be provided with this connection piece 7 or the auxiliary connection piece 8. FIG.
