Description

本発明は、建物の合成スラブ等を形成するデッキプレートの凹部空間内に取着され、天井裏空間に配線、配管されるケーブル、電線管、送水管等の配線・配管材を吊持する配線・配管材用吊具に関するものである。   The present invention is a wiring that is mounted in a recessed space of a deck plate that forms a composite slab or the like of a building, and that suspends wiring and piping materials such as cables, conduits, and water pipes that are wired and piped in the ceiling space. -It relates to a hanging tool for piping materials.

建物の床スラブの形成においては、型枠の取外し作業を省略して施工の省力化、工期の短縮を図るべく、デッキプレートが使用されている。デッキプレートは強度を保持するために波付形状に形成された広幅帯鋼であり、これを鉄骨梁等の上に多数並べて配置された後、その上面にコンクリートが打設することにより、合成構造の床スラブを形成することができる。このような合成スラブの下面を形成するデッキプレートの凹部空間にはその両側壁に形成された補剛溝や段部を利用して吊具が取着され、この吊具には吊り天井の野縁などが吊持されており、また、ケーブル、電線管、送水管等の配線・配管材などが吊持されることもある。   In the formation of floor slabs for buildings, deck plates are used to save work and shorten the construction period by eliminating the work of removing the formwork. The deck plate is a wide band steel formed in a wavy shape to maintain strength, and after placing a large number of these on a steel beam, etc., concrete is cast on the upper surface of the composite structure. Floor slabs can be formed. Hangings are attached to the recessed space of the deck plate that forms the lower surface of such a composite slab using stiffening grooves and steps formed on both side walls thereof. Edges and the like are suspended, and wiring and piping materials such as cables, electric lines, and water pipes may be suspended.

図２０はこの種の吊具を示す。図２０において、吊具５１は吊りボルト５２が螺挿されるボルト螺挿部５３と、ボルト螺挿部５３から両側に斜め下方に向けて延設された一対の翼部５４，５４とで構成されている。一対の翼部５４，５４は取着時に両先端がデッキプレート３１の両側壁に長手方向に沿って形成された補剛溝３９内に嵌入係止される大きさに形成されている。この吊具５１をデッキプレート３１に取着するには、まず、両翼部５４をデッキプレート３１の凹部空間３６内に強制的に押し入れ、両先端を補剛溝３９内に嵌入係止させる。次いで、吊りボルト５２を螺挿させてその上先端部を凹部空間３６の天壁３７に当接させ、更に螺挿を継続する。すると、翼部５４におけるボルト螺挿部５３側の端部は図２０の下方に押し下げられるため、翼部５４は、他端部である先端がデッキプレート３１の補剛溝３９の側壁面に強く押付けられ、突張り状態となる。これにより、吊具５１は強固にデッキプレート３１の凹部空間３６内に取着される。   FIG. 20 shows this type of hanger. In FIG. 20, the hanger 51 includes a bolt screwing portion 53 into which a hanging bolt 52 is screwed and a pair of wing portions 54, 54 extending obliquely downward from both sides of the bolt screwing portion 53. ing. The pair of wing parts 54 and 54 are formed in such a size that both ends are fitted and locked in the stiffening grooves 39 formed along the longitudinal direction on both side walls of the deck plate 31 at the time of attachment. In order to attach the hanger 51 to the deck plate 31, first, both wings 54 are forcibly pushed into the recessed space 36 of the deck plate 31, and both ends are fitted and locked in the stiffening groove 39. Next, the suspension bolt 52 is screwed to bring the upper end portion into contact with the top wall 37 of the recessed space 36, and the screwing is continued. Then, the end of the wing portion 54 on the bolt screwing portion 53 side is pushed downward in FIG. 20, so that the tip of the wing portion 54 is strongly against the side wall surface of the stiffening groove 39 of the deck plate 31. It is pressed and is in a stretched state. Thereby, the hanging tool 51 is firmly attached in the recessed space 36 of the deck plate 31.

この種の吊具に関しては、実開平６−３７４１７号公報に記載の吊りボルト係着金具や実開平６−８２２２７号公報に記載のデッキプレート用天井吊り金具等、各種の技術が開示されている。   With regard to this type of hanging tool, various techniques such as a hanging bolt engaging metal fitting described in Japanese Utility Model Laid-Open No. 6-37417 and a ceiling hanging metal fitting for a deck plate described in Japanese Utility Model Laid-Open No. 6-82227 are disclosed. .

実開平６−３７４１７号公報Japanese Utility Model Publication No. 6-37417 実開平６−８２２２７号公報Japanese Utility Model Publication No. 6-82227

しかし、前記公報を含め、この種の吊具は、いずれも、デッキプレート３１の凹部空間３６内に嵌入した後、吊りボルト５２を螺挿して両翼部５４の先端をデッキプレート３１の両側壁の補剛溝３９や段部に押付け突張らせることによりデッキプレート３１に取着している。このため、デッキプレート３１に取着するには吊りボルト５２を螺挿しなければならないから、面倒で手間のかかる作業となっていた。また、通常、デッキプレート３１には多数の吊具が取着されるから、全ての取着作業には多大な時間を要した。更に、吊りボルト５２が必要であるため、部品数が増え、構成が複雑化するとともにコスト高ともなっていた。   However, all of these types of lifting devices including the above-mentioned publications are inserted into the recessed space 36 of the deck plate 31 and then screwed with the suspension bolts 52 so that the tips of both wings 54 are located on both side walls of the deck plate 31. The deck plate 31 is attached to the stiffening groove 39 or the stepped portion by pressing and protruding. For this reason, in order to attach to the deck plate 31, since the suspension bolt 52 must be screwed in, it was a troublesome and time-consuming work. In addition, since a large number of hanging tools are usually attached to the deck plate 31, it takes a lot of time for all the attaching operations. Further, since the suspension bolt 52 is necessary, the number of parts is increased, the configuration is complicated, and the cost is high.

また、天井裏空間において、吊り天井の野縁等でなく、床スラブ面に沿って布設される配線・配管材を所定間隔毎に吊持する場合は、吊具５１をデッキプレート３１に取着してからでないと配線・配管材を吊持することはできなかった。即ち、先に吊具５１の吊りボルト５２の下端部に取付具を介して配線・配管材を水平姿勢に保持させてから吊りボルト５２を回転し螺挿しようとしても、これに保持されている配線・配管材も共に吊りボルト５２を軸に水平方向に回転することになるから、後から吊りボルト５２を螺挿することはできない。したがって、先に吊具５１をデッキプレート３１に取着してから吊りボルト５２の下端部に配線・配管材を吊持することが必要である。その結果、作業手順が制約されるとともに、デッキプレート３１に取着した吊具５１に配線・配管材を保持させる作業も天井裏の高所で行なわなければならないから、作業性が低下したり危険性も伴うこともある。   In addition, when the wiring / pipe material laid along the floor slab surface is suspended at a predetermined interval in the ceiling space instead of the edge of the suspended ceiling, the hanging tool 51 is attached to the deck plate 31. Only then could the wiring and piping materials be suspended. That is, the wiring bolt / pipe material is held in the horizontal posture through the fixture at the lower end portion of the suspension bolt 52 of the suspension tool 51, and then the suspension bolt 52 is held by the rotation bolt. Since both the wiring and piping material rotate in the horizontal direction around the suspension bolt 52, the suspension bolt 52 cannot be screwed later. Therefore, it is necessary to first suspend the wiring / pipe material from the lower end of the suspension bolt 52 after attaching the suspension tool 51 to the deck plate 31 first. As a result, the work procedure is restricted, and the work of holding the wiring / pipe material on the hanging tool 51 attached to the deck plate 31 must be performed at a high position behind the ceiling. It may be accompanied by sex.

そこで、本発明は、天井裏空間等において布設される配線・配管材を吊持するものにおいて、デッキプレートに簡単に取着でき、簡易な構成で安価に形成できるとともに、配線・配管材を保持した状態でもデッキプレートに取着できる配線・配管材用吊具の提供を課題とするものである。   Therefore, the present invention suspends wiring / piping materials installed in the space behind the ceiling, etc., and can be easily attached to the deck plate, can be formed at a low cost with a simple structure, and holds the wiring / piping materials. An object of the present invention is to provide a wiring / pipe material hanger that can be attached to a deck plate even in such a state.

請求項１の配線・配管材用吊具は、デッキプレートに形成された、天壁と該天壁の両端から連続する両側壁と該両側壁の先端間に設けられた開口とが長手方向に連続する凹部空間内に取着されるものであって、前記デッキプレートの凹部空間の両側壁に長手方向に連続する凹条部または凸条部により形成された対向する一対の段部に係止する、前記開口の幅より大きく離間して位置する一対の係止部と、該一対の係止部を前記開口の幅より小さく近接させる弾性変形部と、前記天壁に当接する当接部と、を有する本体部を備え、前記本体部には、配線・配管材を直接または別体の吊持部材を介して吊持する吊持部が設けられている。更に、前記本体部は、前記両係止部を相対的に近接するように前記弾性変形部を変形させて前記デッキプレートの開口から嵌入するとともに、前記弾性変形部の弾性復帰力により前記デッキプレートの段部に前記両係止部を係止させることで、前記当接部を前記天壁に当接または略当接させるようにして前記凹部空間内に取着可能となっている。そして、前記当接部は、前記天壁に当接することで、前記吊具の揺動または前記デッキプレートの長手方向への傾動により前記両係止部の前記段部への係止状態が解除されて前記吊具が該デッキプレートから離脱するのを防止するものである。   The suspension member for wiring / piping material according to claim 1 includes a top wall, a side wall continuous from both ends of the top wall, and an opening provided between the ends of the side walls in the longitudinal direction. It is attached in a continuous concave space, and is locked to a pair of opposed step portions formed by concave ridges or convex ridges continuous in the longitudinal direction on both side walls of the concave space of the deck plate. A pair of locking portions that are positioned far apart from the width of the opening, an elastic deformation portion that brings the pair of locking portions closer than the width of the opening, and a contact portion that contacts the top wall The main body portion is provided with a suspension portion for suspending the wiring / pipe material directly or via a separate suspension member. Further, the main body portion is inserted into the opening of the deck plate by deforming the elastic deformation portion so that the both locking portions are relatively close to each other, and the deck plate is elastically restored by the elastic return force of the elastic deformation portion. By locking the both locking portions to the step portion, the contact portion can be attached to the recessed space so as to contact or substantially contact the top wall. And the said contact part contact | abuts to the said top wall, and the latching state to the said step part of both said latching parts is cancelled | released by the rocking | fluctuation of the said hanging tool or the tilting to the longitudinal direction of the said deck plate. Thus, the hanging tool is prevented from being detached from the deck plate.

前記吊具は、弾性変形部が有する弾性復帰力により両係止部をデッキプレートの両段部に圧接させ突張らせて横架取着されるから、弾性変形部を弾性変形させつつ本体部をデッキプレートの開口から強制的に嵌入させるだけで取着することができる。   The hanging tool is attached to the both sides of the deck plate by the elastic restoring force of the elastic deforming portion so as to be pressed against and extended from the stepped portion of the deck plate, so that the main body portion is elastically deforming the elastic deforming portion. Can be attached simply by forcing them through the openings in the deck plate.

その一方、両係止部をデッキプレートの両段部に圧接係止させ、本体部を段部間に横架させているから、デッキプレートへの取着の際にまたは取着後において、吊具が揺動し、即ち、吊持された配線・配管材の突き上げによって吊具が凹部空間への嵌入方向に往復移動或いは振動したり、吊具がデッキプレートの長手方向に傾動し、即ち、吊具が両係止部を結ぶ直線を軸としてデッキプレートの長手方向に回動して傾斜すると、デッキプレートの段部に対する係止部の係止状態が解除され、吊具がデッキプレートから離脱し、脱落してしまうことがある。
このため、請求項１の吊具は、特に、この係止部の係止状態が解除されて吊具が離脱するのを防止すべく当接部を設けている。具体的には、例えば本体部の端縁部等により形成された当接部がデッキプレートの天壁に当接することにより前記揺動及び傾動を阻止するようになっている。 On the other hand, both locking parts are pressed against and locked to both stepped parts of the deck plate, and the main body part is placed horizontally between the stepped parts, so that it can be suspended during or after mounting on the deck plate. The tool swings, that is, the lifting tool reciprocates or vibrates in the direction of insertion into the recessed space by pushing up the suspended wiring / piping material, or the lifting tool tilts in the longitudinal direction of the deck plate, When the hanging tool pivots and tilts in the longitudinal direction of the deck plate around the straight line connecting the two latching parts, the latching state of the latching part with respect to the step part of the deck plate is released, and the lifting tool is detached from the deck plate. And may fall off.
For this reason, the hanging tool according to claim 1 is provided with an abutting portion to prevent the hanging tool from being detached by releasing the locked state of the locking portion. Specifically, for example, the abutting portion formed by the edge portion of the main body abuts against the top wall of the deck plate to prevent the swinging and tilting.

ここで、当接部はデッキプレートの天壁に当接することにより吊具の揺動及び傾動を防止するものであるが、その当接部による当接は離脱しない程度に僅かに揺動または傾動してからデッキプレートの天壁に当接する場合を含む。即ち、当接部は、吊具がデッキプレートの凹部空間に嵌入された時点においては天壁から僅かに離間しているが、吊具が僅かに天壁方向等に揺動したりデッキプレートの長手方向に僅かに傾動したときに天壁に当接してそれ以上の揺動及び傾動を阻止する場合を含む。請求項における略当接とは、当接部がこのように当初はデッキプレートの天壁に近接した状態にあるものの、吊具の揺動または傾動に伴ってデッキプレートの天壁に当接することを意味する。   Here, the abutment portion prevents the suspension tool from swinging and tilting by contacting the top wall of the deck plate, but the contact by the contact portion slightly swings or tilts to the extent that it does not disengage. Then, the case of contacting the top wall of the deck plate is included. That is, the abutting portion is slightly separated from the top wall when the hanging tool is inserted into the recessed space of the deck plate, but the hanging tool slightly swings in the direction of the ceiling wall or the like. This includes the case where the rocker is in contact with the top wall when tilted slightly in the longitudinal direction to prevent further rocking and tilting. The substantially abutting in the claims means that the abutting part is initially in the state of being close to the top wall of the deck plate, but abuts on the top wall of the deck plate as the suspension swings or tilts. Means.

また、請求項１の吊具は、比較的軽量な配線・配管材を適宜間隔をおいて吊持するものに適用されるから、弾性変形部の弾性復帰力によって両係止部がデッキプレートの両段部に圧接され本体部が両段部間に横架された取着状態において、吊具が配線・配管材及び自身の荷重によってデッキプレートから離脱し脱落することはない。   In addition, since the hanging tool of claim 1 is applied to a relatively lightweight wiring / pipe material that is suspended at an appropriate interval, both locking portions are made of the deck plate by the elastic restoring force of the elastic deformation portion. In the attached state in which the main body is pressure-contacted to both the stepped portions and is horizontally mounted between the two stepped portions, the hanging tool is not detached from the deck plate due to the wiring / pipe material and its own load and falling off.

請求項２の配線・配管材用吊具は、本体部が帯板状に形成されている。
請求項３の配線・配管材用吊具は、係止部が前記帯板状の本体部の長さ方向の両端側にそれぞれ設けられている。
請求項４の配線・配管材用吊具は、本体部が、両端側の係止部がデッキプレートの段部に係止した状態で略中央が天壁に当接または略当接するアーチ状に配置可能な長さを有している。 In the wire / pipe material hanger according to claim 2, the main body is formed in a band plate shape.
In the wire / pipe material hanger according to a third aspect of the present invention, the engaging portions are respectively provided on both end sides in the length direction of the band plate-shaped main body.
The suspension member for wiring / piping material according to claim 4 has an arch shape in which the main body part is in contact with or substantially in contact with the top wall in a state where the engaging parts on both end sides are engaged with the stepped part of the deck plate. It has a length that can be arranged.

請求項５の配線・配管材用吊具は、弾性変形部が、略弧状に湾曲形成されている。ここで、本体部は、当然であるが、配線・配管材を吊持するものであるから、吊持側とは反対側が凸となる弧状に形成される。
請求項６の配線・配管材用吊具は、弾性変形部が、本体部の全体に渡って設けられている。 In the wiring / pipe material hanger according to claim 5, the elastically deforming portion is curved and formed in a substantially arc shape. Here, as a matter of course, the main body portion suspends the wiring / piping material, and thus is formed in an arc shape in which the opposite side to the suspending side is convex.
In the wiring / pipe material hanger according to a sixth aspect, the elastically deforming portion is provided over the entire body portion.

請求項７の配線・配管材用吊具は、本体部が、長さ方向の略中央に吊持部が設けられているとともに、該吊持部の両側に、係止部を先端側に備えた弾性変形部が設けられている。   In the wire / pipe material hanger according to claim 7, the main body portion is provided with a suspension portion at a substantially central portion in the length direction, and provided with locking portions on both sides of the suspension portion on the tip side. An elastic deformation part is provided.

請求項８の配線・配管材用吊具は、弾性変形部の係止部側が吊持部側よりも弾性変形し易く設けられている。具体的には、他の部分にビードや補強リブなどの補強突条を形成したり幅方向の両縁部にフランジを形成するなどして剛性を高めて弾性変形し難いものし、反面、両係止部の周辺は補強突条などを形成しないことにより弾性変形し易いものとしている。   The suspension member for wiring / pipe material according to claim 8 is provided such that the locking portion side of the elastic deformation portion is more easily elastically deformed than the suspension portion side. Specifically, reinforcement ridges such as beads and reinforcing ribs are formed on other parts, and flanges are formed on both edges in the width direction to increase rigidity and prevent elastic deformation. The periphery of the locking portion is easily elastically deformed by not forming a reinforcing protrusion or the like.

請求項９の配線・配管材用吊具は、係止部が、略弧状に湾曲形成された弾性変形部の先端を、該弾性変形部の弧の凸側方向に折曲形成させて設けられている。即ち、係止部はデッキプレートの両側壁の段部に嵌入する方向に折曲形成されている。本体部が弧状に形成されていると、その両先端に形成された係止部はデッキプレートの両側壁面に沿うような方向に延出し、両側壁の段部との係止が不十分となるおそれがあるので、それを防止するためである。   In the wire / pipe material hanger according to claim 9, the engaging portion is provided by bending the tip of the elastically deforming portion formed in a substantially arc shape in the convex direction of the arc of the elastically deforming portion. ing. That is, the locking portion is bent in a direction to be fitted into the step portions on both side walls of the deck plate. When the main body portion is formed in an arc shape, the locking portions formed at both ends of the main body portion extend in a direction along the both side wall surfaces of the deck plate, and the locking with the step portions on both side walls becomes insufficient. This is to prevent it because there is a fear.

請求項１０の配線・配管材用吊具は、吊持部が、別体の紐状体からなる吊持部材が取付けられてなる。ここで、紐状体には、所定幅のバンド体等も含まれる。これにより、配線・配管材は紐状体を結束して吊持される。   In the wire / pipe material hanger according to claim 10, the hanger is provided with a hung member made of a separate string-like body. Here, the string-like body includes a band body having a predetermined width. As a result, the wiring / pipe material is suspended by binding the string-like body.

請求項１１の配線・配管材用吊具は、本体部の略全体が、デッキプレートの凹部空間内に入り込み、吊持部が、前記凹部空間外で配線・配管材を吊持可能な長さに設けられている。   The wire / pipe material hanger according to claim 11 is such that substantially the whole main body portion enters the recessed space of the deck plate, and the suspension portion is capable of suspending the wiring / pipe material outside the recessed space. Is provided.

請求項１の発明は、弾性復帰力により両係止部をデッキプレートの両段部に圧接させ本体部を突張らせて取着する構成となっているから、弾性変形部を弾性変形させつつデッキプレートの開口から強制的に押し込んで凹部空間内に嵌入させるだけで簡単にデッキプレートに取着することができる。   According to the first aspect of the present invention, since the both locking portions are pressed against both step portions of the deck plate by the elastic restoring force and the main body portion is stretched and attached, the elastic deformation portion is elastically deformed. It can be easily attached to the deck plate simply by forcibly pushing it through the opening of the deck plate and fitting it into the recessed space.

そして、特に、本体部に当接部を備えているので、吊具が上記のように弾性復帰力により両係止部がデッキプレートの両端部に圧接されるだけで取着される簡易な構成のものであるにも拘わらず、吊持されている配線・配管材の揺れ等によって吊具が揺動したりデッキプレートの長手方向に傾動したりして係止部の係止状態が解除され吊具が離脱するのを簡易な構成で確実に防止することができ、吊具を安定してデッキプレートに取着し保持させることができる。   In particular, since the main body portion is provided with a contact portion, a simple configuration in which the hanging tool is attached simply by pressing the both locking portions to both end portions of the deck plate by the elastic return force as described above. In spite of being a thing of the thing, the suspension of the latching part is released because the hanging tool swings or tilts in the longitudinal direction of the deck plate due to the swing of the suspended wiring or piping material, etc. It is possible to reliably prevent the lifting tool from being detached with a simple configuration, and it is possible to stably attach and hold the lifting tool to the deck plate.

また、従来の吊具のような吊りボルトを用いることなく取着できるので、構成が簡易であり、安価に製造できる。更に、吊具は回転させたりすることなくそのままの姿勢でデッキプレートの開口から単に強制的に押し込むだけで凹部空間内に取着できるから、吊持部材に配線・配管材を保持した状態でも取着することができ、天井に近い高所に登ることなく吊持部材に配線・配管材を保持させることもできる。それにより、配線・配管材を吊持部材に取付ける作業性が向上し、また、その作業を安全に行なうことができる。   Moreover, since it can be attached without using a hanging bolt such as a conventional hanging tool, the configuration is simple and it can be manufactured at low cost. Furthermore, since the hanging tool can be installed in the recessed space by simply forcibly pushing it through the opening of the deck plate without rotating it, it can be installed even when the wiring / pipe material is held on the hanging member. The suspension member can hold the wiring / pipe material without climbing to a high place near the ceiling. Thereby, the workability of attaching the wiring / pipe material to the suspension member is improved, and the work can be performed safely.

請求項２の発明は、本体部を帯板状のバネ鋼板等を使用して簡易な構成で安価に形成できる。また、本体部を弧状に湾曲させることにより簡単に弾性変形させ、弾性復帰力を得ることができる。
請求項３の発明は、係止部が本体部の長さ方向の両端側にそれぞれ設けられているので、左右対称構造とすることができ、バランスの良い均等な吊持状態を得ることができる。
請求項４の発明は、本体部をアーチ状に配置して左右対称構造とすることにより、請求項３と同様に、バランスの良い均等な吊持状態を得ることができる。 According to the invention of claim 2, the main body can be formed at a low cost with a simple configuration using a strip-shaped spring steel plate or the like. Further, the main body can be easily elastically deformed by bending it in an arc shape to obtain an elastic restoring force.
According to the invention of claim 3, since the engaging portions are provided at both ends in the length direction of the main body portion, it is possible to have a bilaterally symmetric structure and to obtain a balanced and uniform suspended state. .
In the invention of claim 4, by arranging the main body portion in an arch shape to form a bilaterally symmetric structure, a balanced and uniform suspended state can be obtained as in the case of claim 3.

請求項５及び請求項６の発明は、弾性変形部が弧状に形成されているので、弾性変形部を弾性的に更に湾曲させるだけで所要の弾性復帰力を得ることができ、デッキプレートの開口から嵌入させるだけの操作でかつ簡易な構成で両係止部をデッキプレートの段部の側壁面に圧接させ吊具を保持させることができる。   In the inventions according to claims 5 and 6, since the elastic deformation portion is formed in an arc shape, the required elastic return force can be obtained only by further elastically bending the elastic deformation portion, and the opening of the deck plate can be obtained. It is possible to hold the hanger by pressing both the locking portions against the side wall surface of the stepped portion of the deck plate with a simple configuration with an operation that is simply inserted from the side.

請求項７の発明は、本体部の長さ方向の略中央に吊持部が設けられ、該吊持部の両側に、係止部を先端側に備えた弾性変形部が設けられているので、請求項３及び請求項４と同様に、バランスの良い均等な吊持状態を得ることができる。   In the seventh aspect of the invention, the suspension portion is provided at the approximate center in the length direction of the main body portion, and the elastic deformation portions having the locking portions on the distal end side are provided on both sides of the suspension portion. Similarly to the third and fourth aspects, a balanced and uniform suspended state can be obtained.

請求項８の発明は、弾性変形部の係止部側が吊持部側よりも弾性変形し易く設けられているので、デッキプレートの段部に弾性的に係止させる必要のある係止部側においては所要の弾性復帰力を確保することができる。反面、吊持部側は係止部側より剛性が大きく、配線・配管材の揺動や引張りによる力によって弾性変形が生じにくいため、前記力が係止部側に伝わりにくく、したがって、係合が解除される方向への弾性変形を抑えることができ、デッキプレートからの離脱をより確実に防止できる。   In the eighth aspect of the invention, since the locking portion side of the elastic deformation portion is provided more easily to be elastically deformed than the suspension portion side, the locking portion side that needs to be elastically locked to the step portion of the deck plate. In this case, the required elastic restoring force can be secured. On the other hand, the suspension part side has greater rigidity than the locking part side, and is less likely to be elastically deformed by the force caused by swinging or pulling of the wiring / pipe material, so that the force is not easily transmitted to the locking part side. The elastic deformation in the direction in which the is released can be suppressed, and the separation from the deck plate can be more reliably prevented.

請求項９の発明は、係止部が、弾性変形部の先端を、該弾性変形部の弧の凸側方向に折曲形成させて設けられているので、両係止部をデッキプレートの両側壁の段部の奥方に当接させて確実に係止させることができる。   According to the ninth aspect of the present invention, since the engaging portion is provided by bending the tip of the elastically deforming portion in the convex direction of the arc of the elastically deforming portion, both engaging portions are provided on both sides of the deck plate. It can be brought into contact with the back of the stepped portion of the wall and securely locked.

請求項１０の発明は、吊持部が、別体の紐状体からなる吊持部材が取付けられてなるので、吊持されている配線・配管材に引張り力等の外力が加わってもその力は吊持部材である紐状体が吸収するから、本体部まで伝搬することがない。このため、前記力によって本体部が変形するのが防止され、本体部の変形によって係止部がデッキプレートの段部から離脱してしまうのを防止することができる。   In the invention of claim 10, since the suspension member is formed by attaching a suspension member made of a separate string-like body, even if an external force such as a tensile force is applied to the suspended wiring / pipe material, The force is not propagated to the main body because the string-like body as the suspension member absorbs the force. For this reason, it can prevent that a main-body part deform | transforms with the said force, and can prevent that a latching | locking part detaches | leaves from the step part of a deck plate by a deformation | transformation of a main-body part.

請求項１１の発明は、本体部の略全体がデッキプレートの凹部空間内に入り込むので、本体部が外部物体との接触によってデッキプレートから離脱するのを抑えることができる。また、吊持部が凹部空間外で配線・配管材を吊持可能な長さに設けられているので、凹部空間外の広いスペースにおいて配線・配管材の結束作業を円滑かつ楽に行なうことができる。   According to the eleventh aspect of the present invention, since the entire main body portion enters the recessed space of the deck plate, it is possible to suppress the main body portion from being detached from the deck plate due to contact with an external object. In addition, since the suspension part is provided with a length that allows the wiring / pipe material to be suspended outside the recessed space, the wiring / pipe material can be bundled smoothly and easily in a wide space outside the recessed space. .

以下、本発明の実施形態の配線・配管材用吊具を図に基づいて説明する。ここで、図１及び図２は前記吊具を示し、図３及び図４は前記吊具が取着されるデッキプレートを示す。
図１及び図２において、吊具１は、図３及び図４に示す建物の合成スラブ等を構成する波付形状の広幅帯鋼からなるデッキプレート３１の凹部空間３６に取着され、天井裏に布設される配線・配管材を吊持し保持するものである。吊具１の主体をなす本体部２は、円弧状の帯板で形成され、長さ方向の中央に設けられた吊持部３と、該吊持部３の両側に設けられた弾性変形部４と、該弾性変形部４の先端側に形成され、デッキプレート３１の凹部空間３６の両側壁３８の一対の段部３８ｃ，３８ｃに係止する一対の係止部５，５と、デッキプレート３１の天壁３７に当接する当接部６とを有している。前記吊持部３は別体の吊持部材であるバインド線２１を介して配線・配管材としてのケーブルＣを吊持するようになっている。前記弾性変形部４は一対の係止部５，５をデッキプレート３１の開口３５の幅より小さい間隔まで近接させる変形能力を有している。前記当接部６は吊具１が揺動したりデッキプレート３１の長手方向に傾動することにより係止部５の係止状態が解除されて本体部２がデッキプレート３１から離脱するのを防止すべくデッキプレート３１の天壁３７に当接する。 Hereinafter, the wire / pipe material hanger according to an embodiment of the present invention will be described with reference to the drawings. Here, FIG.1 and FIG.2 shows the said hanging tool, FIG.3 and FIG.4 shows the deck plate to which the said hanging tool is attached.
1 and 2, the hanging tool 1 is attached to a recessed space 36 of a deck plate 31 made of corrugated wide steel strip that constitutes the composite slab of the building shown in FIGS. 3 and 4. It is intended to suspend and hold the wiring / pipe material installed in the cable. A main body 2 that forms the main body of the hanging tool 1 is formed of an arc-shaped strip, a hanging part 3 provided in the center in the length direction, and an elastically deforming part provided on both sides of the hanging part 3. 4, a pair of locking portions 5, 5 formed on the distal end side of the elastically deforming portion 4 and locked to a pair of step portions 38 c, 38 c on both side walls 38 of the recessed space 36 of the deck plate 31, a deck plate And the abutting portion 6 that abuts the top wall 37 of 31. The suspension part 3 is configured to suspend a cable C as a wiring / piping material via a bind wire 21 which is a separate suspension member. The elastic deformable portion 4 has a deformability capable of bringing the pair of locking portions 5 and 5 closer to an interval smaller than the width of the opening 35 of the deck plate 31. The abutting portion 6 prevents the main body 2 from being detached from the deck plate 31 when the hook 1 swings or tilts in the longitudinal direction of the deck plate 31 to release the locking state of the locking portion 5. As much as possible, it abuts against the top wall 37 of the deck plate 31.

したがって、吊具１の本体部２は、デッキプレート３１の開口３５からデッキプレート３１の凹部空間３６内に強制的に嵌入された後、弾性変形部４の弾性復帰力により両係止部５がデッキプレート３１の段部３８ｃに圧接されるようになっている。また、本体部２は、デッキプレート３１の凹部空間３６内に嵌入された後、中央部が、図８等に示すように、デッキプレート３１の天壁３７に当接または略当接した状態で横架されるようになっている。以下、各構成部材について詳細に説明する。   Therefore, after the main body 2 of the hanger 1 is forcibly inserted into the recessed space 36 of the deck plate 31 from the opening 35 of the deck plate 31, the both locking portions 5 are moved by the elastic return force of the elastic deformation portion 4. The deck plate 31 is pressed against the stepped portion 38c. Further, after the main body 2 is inserted into the recessed space 36 of the deck plate 31, the central portion is in contact with or substantially in contact with the top wall 37 of the deck plate 31, as shown in FIG. It is designed to be laid horizontally. Hereinafter, each component will be described in detail.

まず、前記本体部２は、ステンレス等を使用したバネ鋼材で一定幅の帯板状に形成され、左右対称をなし、全体が略円弧状に形成され、弾性変形可能となっている。そして、図８に示すように、長手方向の端部間の平面投影寸法Ｌ１は、デッキプレート３１の開口３５の幅寸法Ｌ２より大きく形成されており、外方から両端部を弾性的に圧縮して端部間の平面投影寸法Ｌ１を縮小させつつ強制的にデッキプレート３１の開口３５から凹部空間３６内に嵌入させ、先端の係止部５をデッキプレート３１の段部３８ｃに係止させることができるようになっている。つまりは、本体部２は、両端側の係止部５がデッキプレート３１の段部３８ｃに係止した状態で中央が天壁３７に当接または略当接するアーチ状に配置可能な長さを有している。ここで、本体部２は、弾性変形するものであるが、剛性が小さ過ぎると、吊具１をデッキプレート３１の凹部空間３６内に横架状態で取着しても吊持したケーブルＣや自身の荷重によって円弧の反りが反対側に反転してしまうので、本体部２はこれらの点を考慮して最適な弾性変形状態が得られるように材質、板厚等が選定される。   First, the main body 2 is made of a spring steel material using stainless steel or the like and is formed in a strip shape having a constant width, is symmetrical, is formed in a substantially arc shape, and is elastically deformable. As shown in FIG. 8, the plane projection dimension L1 between the end portions in the longitudinal direction is formed larger than the width dimension L2 of the opening 35 of the deck plate 31, and both ends are elastically compressed from the outside. Thus, the planar projection dimension L1 between the end portions is reduced and forcibly fitted into the recessed space 36 from the opening 35 of the deck plate 31, and the locking portion 5 at the tip is locked to the step portion 38c of the deck plate 31. Can be done. That is, the main body 2 has a length that can be arranged in an arch shape in which the center abuts or substantially abuts against the top wall 37 in a state where the engaging portions 5 on both end sides are engaged with the stepped portion 38c of the deck plate 31. Have. Here, the main body 2 is elastically deformed, but if the rigidity is too small, the cable C or the cable C that is suspended even if the hanging tool 1 is mounted in the recessed space 36 in the deck plate 31 in a horizontally mounted state. Since the curvature of the arc is reversed to the opposite side by its own load, the main body 2 is selected in terms of material, plate thickness and the like so as to obtain an optimal elastic deformation state in consideration of these points.

本体部２の長さ方向の中央部に設けられた吊持部３は、ケーブルＣを吊持する別体の吊持部材であるバインド線２１が取付けられてなり、本体部の円弧線から僅かに図２の下方に段状に後退して形成された収納凹部７内に、バインド線２１を取付けるための被取付部材８が収納された状態で固定されている。被取付部材８は樹脂材、金属材等を使用して薄い円盤状に形成されているとともに、裏面中央部には小径の円柱状の突出部８ａが一体に形成されており、突出部８ａは収納凹部７の中央部に設けられた貫通孔７ａを貫通し、下方に突出している。更に、被取付部材８は中央にバインド線２１を貫通させて取付けるための小孔８ｂが２個上下方向に貫設されている。ここで、突出部８ａを設けたのは、被取付部材８の固定箇所を位置決めする他、小孔８ｂから下方に飛び出したバインド線２１が鋼板からなる本体部２の収納凹部７の貫通孔７ａの周縁角部に接触し、擦られて切断されるのを避けるためである。なお、被取付部材８は接着や圧入等の手段により収納凹部７内に固定される。   The suspension part 3 provided in the central part in the length direction of the main body part 2 is provided with a bind wire 21 which is a separate suspension member for suspending the cable C, and is slightly from the arc line of the main body part. 2 is fixed in a state in which a member 8 to be attached for attaching the binding wire 21 is housed in a housing recess 7 formed by retreating in a stepwise manner downward in FIG. The mounted member 8 is formed in a thin disk shape using a resin material, a metal material, or the like, and a small-diameter columnar protruding portion 8a is integrally formed at the center of the back surface. It penetrates through a through-hole 7a provided in the central part of the housing recess 7 and protrudes downward. Further, the attached member 8 has two small holes 8b penetrating in the vertical direction for attaching the binding wire 21 through the center. Here, the protruding portion 8a is provided in addition to positioning the fixing portion of the attached member 8, and the through-hole 7a of the housing recess 7 of the main body 2 in which the bind wire 21 protruding downward from the small hole 8b is made of a steel plate. This is for avoiding being cut by being touched by rubbing at the peripheral corners of the plate. The attached member 8 is fixed in the housing recess 7 by means such as adhesion or press fitting.

次に、弾性変形部４は、円弧状に湾曲形成され、本体部２の吊持部３の両側に設けられ、本体部２のほぼ全体に渡って設けられている。外面には長手方向に沿ってそれぞれ２本の補強突条であるビード９が設けられている。ビード９は吊持部３の周辺から円弧に沿って下方に延び、係止部５から所定距離離間した位置まで設けられている。これにより、弾性変形部４は全体的には弾性変形可能であるものの、ビード９が設けられている吊持部３側の部分は比較的剛性が高められ、比較的撓み変形し難いものとなっており、配線・配管材の揺動や引張りの力による弾性変形が生じにくいため、また、吊持部３に加わるケーブルＣや吊具１自身の荷重による弾性変形が生じにくいため、前記力が係止部側に伝わりにくい。したがって、弾性変形部４は係止部５の係合が解除される方向に弾性変形し本体部２の円弧の凸側の向きが反対側に反転してしまうのが防止され、図２(b)において上側が凸となる円弧形状に安定して維持される。これにより、吊具１がデッキプレート３１から離脱し落下してしまうのが防止される。その一方、係止部５の部分はビード９が設けられていないので、撓み易くなっており、所要の弾性復帰力を得ることができる。なお、ビード９の形成位置、長さ、数は、本体部２の円弧形状の安定性や弾性復帰力による係止部５の突張り強度等を考慮して設定される。   Next, the elastic deformation portion 4 is formed in a curved shape in an arc shape, provided on both sides of the suspension portion 3 of the main body portion 2, and provided over substantially the entire main body portion 2. The outer surface is provided with beads 9 as two reinforcing protrusions along the longitudinal direction. The bead 9 extends downward along the arc from the periphery of the suspension part 3 and is provided to a position spaced apart from the locking part 5 by a predetermined distance. As a result, although the elastically deformable portion 4 can be elastically deformed as a whole, the portion on the side of the suspension portion 3 provided with the beads 9 has a relatively high rigidity and is relatively difficult to bend and deform. Since the elastic deformation due to the swinging or pulling force of the wiring / pipe material is less likely to occur, and the elastic deformation due to the load of the cable C or the hanging tool 1 itself applied to the suspension portion 3 is less likely to occur, Difficult to be transmitted to the locking part. Accordingly, the elastic deformation portion 4 is elastically deformed in the direction in which the engagement of the locking portion 5 is released, and the direction of the convex side of the arc of the main body portion 2 is prevented from being reversed to the opposite side, and FIG. ) Is stably maintained in a circular arc shape having a convex upper side. This prevents the hanger 1 from being detached from the deck plate 31 and falling. On the other hand, since the bead 9 is not provided in the portion of the locking portion 5, it is easy to bend and a required elastic return force can be obtained. Note that the formation position, length, and number of the beads 9 are set in consideration of the stability of the arc shape of the main body 2 and the tensile strength of the locking portion 5 due to the elastic restoring force.

本体部２の左右一対の係止部５，５は、弾性変形部４の先端側に形成され、相互がデッキプレート３１の開口３５の幅より大きい間隔で離間する位置に設けられている。そして、弾性変形部４の円弧に対して図２(b)の斜め上方向即ちデッキプレート３１の両側壁３８の段部３８ｃに嵌入する方向に所定角度折曲されている。係止部５が弾性変形部４の円弧に沿って設けられていると、デッキプレート３１の両側壁３８の段部３８ｃとの係止が不十分となるおそれがあるからである。この折曲形成により、係止部５はデッキプレート３１の両側壁３８の段部３８ｃの奥方に当接し確実に係止される。   The pair of left and right engaging portions 5, 5 of the main body portion 2 are formed on the distal end side of the elastic deformation portion 4, and are provided at positions that are separated from each other by a distance larger than the width of the opening 35 of the deck plate 31. Then, it is bent at a predetermined angle with respect to the arc of the elastically deforming portion 4 in an obliquely upward direction in FIG. 2 (b), that is, in a direction to fit into the step portions 38 c of the side walls 38 of the deck plate 31. This is because if the locking portion 5 is provided along the arc of the elastic deformation portion 4, the locking with the step portions 38 c of the side walls 38 of the deck plate 31 may be insufficient. Due to this bending, the locking portion 5 comes into contact with the back of the step portions 38c of the side walls 38 of the deck plate 31 and is securely locked.

当接部６は、本体部２の吊持部３の上面即ち円盤形状の被取付部材８の上面８ｃに形成されており、より具体的には、被取付部材８の上面８ｃにおいてデッキプレート３１の長手方向に沿った直径線上に形成されている。当接部６は、デッキプレート３１の天壁３７に当接するものであるが、必ずしも本体部２がデッキプレート３１の凹部空間３６内に嵌入取着された時点で当接するものである必要はない。当接部６が天壁３７に近接した状態にあって、本体部２がデッキプレート３１の凹部空間３６内に嵌入取着された時点では、デッキプレート３１の天壁３７に当接していなくても、本体部２がケーブルＣの突き上げによって上下方向に往復移動、振動する揺動を開始し、または本体部２がデッキプレート３１の長手方向に傾動を開始してから、デッキプレート３１の天壁３７に当接する略当接のものであってもよい。要するところ、ケーブルＣの吊持作業中や吊持後において吊具１がケーブルＣの突き上げによる揺動やデッキプレート３１の長手方向への傾動により係止部５がデッキプレート３１の段部３８ｃから離脱し落下してしまうのをデッキプレート３１の天壁３７との当接により防止するものであればよい。これを別言すれば、当接部６は吊具１の揺動時、傾動時を含めて少なくともデッキプレート３１の天壁３７と当接することを要する。したがって、当接部６とデッキプレート３１の天壁３７とが大きく離間していて、吊具１が傾動したときに、当接部６がデッキプレート３１の天壁３７と全く当接しない場合は除外される。   The contact portion 6 is formed on the upper surface of the suspension portion 3 of the main body 2, that is, the upper surface 8 c of the disk-shaped attached member 8, and more specifically, on the upper surface 8 c of the attached member 8. It is formed on the diameter line along the longitudinal direction of. The abutting portion 6 abuts on the top wall 37 of the deck plate 31, but does not necessarily have to abut when the main body portion 2 is fitted into and attached to the recessed space 36 of the deck plate 31. . When the abutting portion 6 is close to the top wall 37 and the main body portion 2 is fitted into and attached to the recessed space 36 of the deck plate 31, the abutting portion 6 is not in contact with the top wall 37 of the deck plate 31. In addition, the main body 2 starts reciprocating in the vertical direction by the push-up of the cable C and starts swinging to vibrate, or after the main body 2 starts to tilt in the longitudinal direction of the deck plate 31, It may be substantially abutting against 37. In short, during or after the cable C is being hung, the hook 1 is swung by the push-up of the cable C, or the deck plate 31 is tilted in the longitudinal direction, so that the locking portion 5 is lifted from the step portion 38c of the deck plate 31. Any means that prevents the deck plate 31 from falling off and coming into contact with the top wall 37 of the deck plate 31 may be used. In other words, the abutting portion 6 needs to abut at least the top wall 37 of the deck plate 31 including when the hanging tool 1 swings and tilts. Therefore, when the contact part 6 and the ceiling wall 37 of the deck plate 31 are largely separated and the suspension tool 1 tilts, the contact part 6 does not contact the ceiling wall 37 of the deck plate 31 at all. Excluded.

なお、本体部２がデッキプレート３１の凹部空間３６内に嵌入取着された当初から中央の吊持部３がデッキプレート３１の天壁３７と当接している場合は、吊持部３の被取付部材８の上面８ｃの直径部分が当接し、この直径部分が当接部６の形成箇所となる。また、本体部２がデッキプレート３１の凹部空間３６内に嵌入取着された時点で中央の吊持部３が僅かにデッキプレート３１の天壁３７から離間している場合は、吊具１がある程度傾動を開始してから被取付部材８の上面８ｃの直径部分の端角部８ｄがデッキプレート３１の天壁３７と当接することとなるから、この上面８ｃの端角部８ｄが当接部６の形成箇所となる。   In the case where the central suspension portion 3 is in contact with the top wall 37 of the deck plate 31 from the beginning when the main body portion 2 is fitted into and attached to the recessed space 36 of the deck plate 31, the covering portion of the suspension portion 3 is covered. The diameter portion of the upper surface 8 c of the attachment member 8 abuts, and this diameter portion becomes the formation portion of the abutment portion 6. Further, when the central suspension part 3 is slightly separated from the top wall 37 of the deck plate 31 when the main body 2 is fitted into and attached to the recessed space 36 of the deck plate 31, Since the end corner 8d of the diameter portion of the upper surface 8c of the mounted member 8 comes into contact with the top wall 37 of the deck plate 31 after starting to tilt to some extent, the end corner 8d of the upper surface 8c becomes the contact portion. 6 is formed.

ここで、円盤状の被取付部材８は、任意の大きさに形成できるが、小さ過ぎると、デッキプレート３１の天壁３７との当接長さ、当接面積が小さくなり、傾動防止効果が小さくなるので、その点留意する必要がある。   Here, the disk-shaped attached member 8 can be formed in an arbitrary size, but if it is too small, the contact length and the contact area with the top wall 37 of the deck plate 31 are reduced, and the tilt prevention effect is obtained. It will be necessary to keep this in mind.

次に、本体部２の吊持部３を形成する別体の吊持部材は、紐状体により形成されており、凹部空間３６の外方においてケーブルＣを吊持可能な長さに設けられている。吊持部材は、一端側から本体部２の吊持部３の被取付部材８に設けられた２個の小孔８ｂに折り返し状態で挿通し、必要に応じて被取付部材８の下方で結束することによりこの被取付部材８に簡単に取付けることができる。紐状体としては、ケーブルＣを吊持し得るバインド線や吊バンド、結束バンド等を挙げることができ、本実施形態ではバインド線２１を用いている。バインド線２１は針金等の金属芯線が樹脂膜で被覆された断面円形状の細線からなる。したがって、吊持部３から垂下している２本を束ねることにより簡単にケーブルＣを吊持させることができる。また、バインド線２１や吊バンド、結束バンドはその結束を解除することにより簡単にケーブルＣの吊持を解除し、これを取り外すことができる。このため、吊持後にケーブルＣの吊持位置を簡単に変更することもできる。なお、バインド線としては、金属芯線を偏平な細長の樹脂紐で挟んで形成したものなどを用いることもできる。   Next, a separate suspension member that forms the suspension portion 3 of the main body 2 is formed of a string-like body, and is provided with a length that allows the cable C to be suspended outside the recessed space 36. ing. The suspension member is inserted from one end side into two small holes 8b provided in the attachment member 8 of the attachment portion 3 of the main body 2 in a folded state, and is bound below the attachment member 8 as necessary. By doing so, it can be easily attached to the attached member 8. Examples of the string-like body include a bind line, a suspension band, and a binding band that can suspend the cable C. In this embodiment, the bind line 21 is used. The bind wire 21 is formed of a thin wire having a circular cross section in which a metal core wire such as a wire is covered with a resin film. Therefore, the cable C can be easily suspended by bundling the two hanging from the suspension part 3. Further, the binding of the binding wire 21, the suspension band, and the binding band can be easily released by releasing the binding, and the cable C can be removed. For this reason, the suspension position of the cable C can also be changed easily after suspension. In addition, as the binding line, a metal core line formed by sandwiching a flat and slender resin string may be used.

次に、吊具１が取着されるデッキプレート３１は、図３(a)、(b)に示すような波付形状の広幅帯鋼であり、幅方向の両端部に折曲形成された嵌合部３３及び被嵌合部３４を互いに嵌合することにより複数を組付けて梁上に敷設される。そして、デッキプレート３１の上面にコンクリート４２が打設されることにより、図４に示すような建物の合成スラブ４１が形成される。図３(a)において、デッキプレート３１は略台形状をなし、左右の両下端はフランジ３２が水平方向に一体に延設され、更に、その先端部には前記嵌合部３３及び被嵌合部３４が一体に形成されている。台形状の下辺部分には開口３５が形成され、内部は凹部空間３６が形成されている。そして、凹部空間３６の天壁３７及び両側壁３８には強度、剛性を確保するため、天壁３７の中央に下方に突出する円弧突条３７ａが長手方向に沿って一体に形成され、両側壁３８の下部に、外方に後退する凹条部３８ａ及び内方に突出する凸条部３８ｂによって一対の段部３８ｃ、３８ｃが一体に形成されている。一対の段部３８ｃは吊具１の一対の係止部５，５が係止可能となっており、係止部５の先端は段部３８ｃの傾斜面に圧接可能となっている。なお、段部３８ｃは凹条部３８ａまたは凸条部３８ｂのみによって形成されたものもある。また、デッキプレート３１は、図３(b)に示すような、２個の台形が横に並設されたものや、図示しないが、天壁３７に間隔をおいて２個の円弧突条３７ａが並設されたものなど各種形状のものが提供されている。   Next, the deck plate 31 to which the hanging tool 1 is attached is a wide band steel having a corrugated shape as shown in FIGS. 3 (a) and 3 (b), and is bent at both ends in the width direction. By fitting the fitting part 33 and the fitted part 34 together, a plurality of parts are assembled and laid on the beam. Then, by putting concrete 42 on the top surface of the deck plate 31, a composite slab 41 of a building as shown in FIG. 4 is formed. In FIG. 3 (a), the deck plate 31 has a substantially trapezoidal shape, and flanges 32 are integrally extended in the horizontal direction at both left and right lower ends. The part 34 is integrally formed. An opening 35 is formed in the lower side portion of the trapezoidal shape, and a recessed space 36 is formed inside. Further, in order to ensure strength and rigidity on the top wall 37 and both side walls 38 of the recessed space 36, an arc projection 37a projecting downward at the center of the top wall 37 is integrally formed along the longitudinal direction. A pair of stepped portions 38c and 38c are integrally formed at a lower portion of 38 by a concave strip portion 38a that recedes outward and a convex strip portion 38b that projects inward. The pair of stepped portions 38c can be engaged with the pair of engaging portions 5 and 5 of the hanger 1, and the distal end of the engaging portion 5 can be pressed against the inclined surface of the stepped portion 38c. In addition, the step part 38c may be formed only by the concave line part 38a or the convex line part 38b. The deck plate 31 includes two trapezoids arranged side by side as shown in FIG. 3B, or two arc ridges 37a spaced from the top wall 37 (not shown). Various shapes such as those arranged side by side are provided.

次に、上記のように構成された吊具１をデッキプレート３１に取着する方法を説明する。
合成スラブ４１のデッキプレート３１の下方の天井裏において、まず、図５(a)に示すように、建物の床面等の低所などにおいて、本体部２の吊持部３から下垂した２本のバインド線２１を結束し、天井裏においてデッキプレート３１の長手方向と直交して水平方向に引き込まれているケーブルＣを吊持する。なお、ケーブルＣの吊持は吊具１をデッキプレート３１に取着した後に行なうことも可能である。但し、この場合は、天井裏での吊持作業となる。 Next, a method for attaching the hanging tool 1 configured as described above to the deck plate 31 will be described.
In the back of the ceiling below the deck plate 31 of the composite slab 41, first, as shown in FIG. 5 (a), two hangs down from the suspension part 3 of the main body part 2 in a low place such as a floor of a building. The cable C that is drawn in the horizontal direction perpendicular to the longitudinal direction of the deck plate 31 is suspended in the back of the ceiling. The cable C can be hung after the hanger 1 is attached to the deck plate 31. However, in this case, the suspension work is performed behind the ceiling.

次いで、手で吊具１を把持し或いは棒状の工具等を使用して下方から、図５(b)に示すように、吊具１の本体部２を傾斜させて、先に、一方の係止部５、図５(b)においては右側の係止部５をデッキプレート３１の開口３５から凹部空間３６内に挿入し、右側の側壁３８の段部３８ｃに嵌入させ係止させる。次に、他方の係止部５、図５(b)においては左側の係止部５をデッキプレート３１における左側の側壁３８の段部３８ｃの下方に当接させ、更にそのまま押し上げて左側の凸条部３８ｂを強制的に乗り越えさせ、段部３８ｃに係止させる。このとき、弾性変形部４は一対の係止部５，５をデッキプレート３１の開口３５の幅より小さく近接させるように弾性変形するので、円弧状の本体部２を撓ませ曲率半径を更に小さくして左側の係止部５を段部３８ｃ側に移動させることができる。   Next, as shown in FIG. 5 (b), the main body 2 of the hanging tool 1 is tilted from the lower side by grasping the hanging tool 1 with a hand or using a bar-shaped tool or the like. 5B, the right locking portion 5 is inserted into the recessed space 36 from the opening 35 of the deck plate 31, and is fitted into the stepped portion 38c of the right side wall 38 to be locked. Next, the other locking portion 5, in FIG. 5 (b), the left locking portion 5 is brought into contact with the lower side of the step portion 38c of the left side wall 38 of the deck plate 31, and further pushed up as it is. The strip 38b is forcibly moved over and locked to the stepped portion 38c. At this time, the elastic deformation portion 4 is elastically deformed so that the pair of locking portions 5 and 5 are closer to each other than the width of the opening 35 of the deck plate 31, so that the arcuate body portion 2 is bent to further reduce the radius of curvature. Thus, the left locking portion 5 can be moved to the stepped portion 38c side.

これにより、吊具１は、図５(c)に示すように、本体部２が撓んだ状態でデッキプレート３１の一対の段部３８ｃに横架され、凹部空間３６内に取着される。但し、上記は一方の係止部５から順にデッキプレート３１の段部３８ｃに嵌入させ圧接させているが、本体部２を水平状態として下方から押し上げ、両係止部５を同時にデッキプレート３１の両段部３８ｃに圧接し係止させることも可能である。図６は取着後に斜め下方から見た吊具１の取着状態を示す。なお、図６においては、ケーブルＣはデッキプレート３１の長手方向に沿って敷設されたものを示す。取着後は、本体部２の当接部６である吊持部３の被取付部材８の上面８ｃはデッキプレート３１の天壁３７の円弧突条３７ａの下端と当接し、或いは、そこから僅かに離間する。以上から分かるように、吊具１は単に下方からデッキプレート３１に向けて押し上げるのみでその凹部空間３６内に取着することができる。   As a result, as shown in FIG. 5C, the hanging tool 1 is horizontally mounted on the pair of stepped portions 38 c of the deck plate 31 in a state where the main body portion 2 is bent, and is attached in the recessed space 36. . However, although the above is inserted into the stepped portion 38c of the deck plate 31 in order from the one locking portion 5 and press-contacted, the main body portion 2 is pushed up from below in a horizontal state, and both the locking portions 5 are simultaneously pushed to the deck plate 31. It is also possible to press and lock both stepped portions 38c. FIG. 6 shows the attachment state of the hanger 1 as viewed from obliquely below after attachment. In FIG. 6, the cable C shows a cable laid along the longitudinal direction of the deck plate 31. After the attachment, the upper surface 8c of the mounted member 8 of the suspension portion 3 which is the abutting portion 6 of the main body portion 2 abuts on or from the lower end of the arc protrusion 37a of the top wall 37 of the deck plate 31. Slightly spaced. As can be seen from the above, the hanging tool 1 can be attached in the recessed space 36 simply by pushing it up from below toward the deck plate 31.

その後は、以上の作業を繰り返すことにより、図７に示すように、複数の吊具１が間隔をおいてデッキプレート３１に取着され、ケーブルＣはこれら複数の吊具１を介して天井裏に吊持される。なお、その後に、ケーブルＣの吊持位置を変更したりする場合は、バインド線２１の結束を外して簡単に行なうことができる。   Thereafter, by repeating the above operation, as shown in FIG. 7, a plurality of hanging tools 1 are attached to the deck plate 31 at intervals, and the cable C is connected to the ceiling back via the plurality of hanging tools 1. Suspended by. After that, when changing the suspension position of the cable C, the binding of the bind wire 21 can be easily removed.

このように取着された吊具１に係る力は、図８に示す釣合状態となる。図８において、吊具１の本体部２を撓ませて円弧の曲率半径を小さくしたことにより本体部２に発生した弾性復帰力はデッキプレート３１の側壁３８の段部３８ｃに矢印で示すように作用している。これに伴い、デッキプレート３１の側壁３８には白抜き矢印で示す反力が発生している。また、吊具１の吊持部３には吊具１自身の荷重及びケーブルＣの荷重により白抜き矢印で示す垂直下方の力が作用している。吊具１は、縦断面内においてこれらの力が釣合い、デッキプレート３１の凹部空間３６内の一定位置に保持されている。   The force applied to the hanger 1 attached in this way is in a balanced state shown in FIG. In FIG. 8, the elastic restoring force generated in the main body 2 by bending the main body 2 of the hanger 1 to reduce the radius of curvature of the arc is indicated by an arrow on the step 38 c of the side wall 38 of the deck plate 31. It is working. Accordingly, a reaction force indicated by a white arrow is generated on the side wall 38 of the deck plate 31. Further, a vertical downward force indicated by a white arrow acts on the suspension portion 3 of the hanging tool 1 due to the load of the hanging tool 1 itself and the load of the cable C. The lifting tool 1 balances these forces in the longitudinal section, and is held at a fixed position in the recessed space 36 of the deck plate 31.

一方、デッキプレート３１の長手方向即ち図８の紙面と直交する方向に関しては、吊具１が単にデッキプレート３１の両段部３８ｃ間に横架されているのみであると、本体部２が帯板状に形成されていてその保持が不安定であることから、取着作業中や取着後においてケーブルＣの揺れなどにより吊具１が揺動し或いはデッキプレート３１の長手方向に傾動し、それが大きければ、係止部５がデッキプレート３１の段部３８ｃから離脱し、更には吊具１がデッキプレート３１から落下するおそれがある。   On the other hand, with respect to the longitudinal direction of the deck plate 31, that is, the direction orthogonal to the paper surface of FIG. 8, if the hanging tool 1 is simply placed between the two step portions 38 c of the deck plate 31, Since it is formed in a plate shape and its holding is unstable, the hanging tool 1 is swung or tilted in the longitudinal direction of the deck plate 31 due to the shaking of the cable C during or after the mounting operation, If it is large, there is a possibility that the locking portion 5 is detached from the stepped portion 38 c of the deck plate 31, and the hanging tool 1 falls from the deck plate 31.

しかし、本発明の吊具１においては、本体部２の中央の吊持部３に当接部６が設けられているので、上記不具合を回避することができる。即ち、当接部６が吊具１の嵌入当初からデッキプレート３１の天壁３７の円弧突条３７ａと当接している場合は、図９(a)に示すように、当接部６である被取付部材８の上面８ｃがデッキプレート３１の天壁３７の円弧突条３７ａと干渉するため、二点鎖線で示す矢印のいずれの方向への傾動も阻止される。ここで、図９は吊具１を側方から見た状態を示す。また、当接部６が取着後において、図９(b)に示すように、デッキプレート３１の天壁３７の円弧突条３７ａから僅かに距離Ｓだけ離間している場合は、吊具１が例えば二点鎖線で示す左方向に僅かに傾きかけたとき、当接部６である被取付部材８の上面８ｃの端角部８ｄがデッキプレート３１の天壁３７の円弧突条３７ａと干渉するため、それ以上の傾動が阻止される。そして、本体部３の上下方向の揺動時においても、当接部６がデッキプレート３１の天壁３７に当接するため、揺動が抑えられる。したがって、吊具１は揺動及びデッキプレート３１の長手方向への傾動も防止され、安定してデッキプレート３１の凹部空間３６内に保持される。   However, in the hanging tool 1 of the present invention, the contact portion 6 is provided in the central suspension portion 3 of the main body portion 2, so that the above problem can be avoided. That is, when the contact portion 6 is in contact with the arc ridge 37a of the top wall 37 of the deck plate 31 from the beginning of the insertion of the hanging tool 1, it is the contact portion 6 as shown in FIG. Since the upper surface 8c of the mounted member 8 interferes with the arc projection 37a of the top wall 37 of the deck plate 31, tilting in any direction of the arrow indicated by the two-dot chain line is prevented. Here, FIG. 9 shows the state which looked at the hanging tool 1 from the side. In addition, as shown in FIG. 9B, when the contact portion 6 is slightly separated from the arc protrusion 37a of the top wall 37 of the deck plate 31 by a distance S as shown in FIG. Is slightly inclined in the left direction indicated by a two-dot chain line, for example, the end corner portion 8d of the upper surface 8c of the attached member 8 that is the contact portion 6 interferes with the arc protrusion 37a of the top wall 37 of the deck plate 31. Therefore, further tilting is prevented. Even when the main body 3 swings in the vertical direction, the contact portion 6 contacts the top wall 37 of the deck plate 31, so that the swing is suppressed. Therefore, the hanging tool 1 is prevented from swinging and tilting in the longitudinal direction of the deck plate 31 and is stably held in the recessed space 36 of the deck plate 31.

次に、本実施形態の吊具１の作用を説明する。
吊具１は、弾性変形部４の弾性復帰力により両係止部５をデッキプレート３１の両段部３８ｃに圧接させ突張らせて取着するものであるから、全体を更に円弧状に撓ませ弾性変形させつつデッキプレート３１の開口３５から強制的に嵌入させるだけの操作で簡単にデッキプレート３１に取着することができる。このとき、本体部２は円弧状に更に湾曲させて弾性的に撓ませることにより簡単に弾性復帰力を得ることができる。 Next, the effect | action of the hanging tool 1 of this embodiment is demonstrated.
Since the hanging tool 1 is attached by pressing the two locking portions 5 against the two step portions 38c of the deck plate 31 by the elastic restoring force of the elastic deformation portion 4, the whole of the hanging tool 1 is further bent into an arc shape. It can be easily attached to the deck plate 31 only by forcibly inserting it from the opening 35 of the deck plate 31 while being elastically deformed. At this time, the main body 2 can be easily bent to be arcuate and elastically bent to easily obtain an elastic restoring force.

そして、特に、吊具１は、本体部２に当接部６を備えているから、施工中や取着後に吊持されているケーブルＣが揺動し、即ちケーブルＣの突き上げによって上下方向等に往復移動したり振動しても、また、ケーブルＣの引張り等によってデッキプレート３１の長手方向に傾動しかけても、前記当接部６がデッキプレート３１の天壁３７の円弧突条３７ａに当接し干渉するため前記揺動及び傾動が阻止され、係止部５の係止状態が解除され係止部５がデッキプレート３１の段部３８ｃから離脱し更には吊具１が脱落するのが簡易な構成によって防止される。その結果、吊具１は円滑にデッキプレート３１に取着されるとともに、いずれの方向にも安定して保持される。   In particular, since the hanger 1 includes the abutment portion 6 in the main body portion 2, the cable C suspended during the construction or after the attachment is swung, that is, the up-down direction or the like by pushing up the cable C. If the cable C is reciprocated or vibrated, or if it is tilted in the longitudinal direction of the deck plate 31 by pulling the cable C or the like, the abutting portion 6 contacts the arc ridge 37a of the top wall 37 of the deck plate 31. Because of the contact and interference, the rocking and tilting are prevented, the locking state of the locking portion 5 is released, the locking portion 5 is released from the stepped portion 38c of the deck plate 31, and the hanging tool 1 is easily removed. Is prevented by a simple configuration. As a result, the hanging tool 1 is smoothly attached to the deck plate 31 and is stably held in any direction.

また、吊具１は、本体部２が帯板状に形成されているとともに、従来の吊具のような吊りボルトを用いることなく取着できるので、この部材が不要であって構成が簡易なものとなり、安価に製造できる。
更に、本体部２は回転させたりすることなくそのままの姿勢で単にデッキプレート３１の開口３５から強制的に押し込むだけで凹部空間３６内に取着されるから、バインド線２１にケーブルＣを保持した状態でも取着することができ、天井に近い高所に登ることなくケーブルＣを吊持することもできる。勿論、ケーブルＣは吊具１をデッキプレート３１に取着してからバインド線２１に吊持させることもできる。 Moreover, since the main part 2 is formed in the shape of a belt plate and the hanger 1 can be attached without using a hanger bolt like a conventional hanger, this member is unnecessary and the structure is simple. Can be manufactured inexpensively.
Further, since the main body 2 is attached in the recess space 36 by simply forcibly pushing it through the opening 35 of the deck plate 31 without rotating it, the cable C is held on the bind wire 21. It can be attached even in a state, and the cable C can be suspended without climbing to a high place near the ceiling. Of course, the cable C can be hung on the bind wire 21 after the hanger 1 is attached to the deck plate 31.

加えて、本体部２は、吊持部３が長さ方向の略中央に設けられ、その両側に弾性変形部４が設けられた左右対称構造となっているので、バランスの良い均等な吊持状態が得られる。   In addition, the main body 2 has a left-right symmetrical structure in which the suspension portion 3 is provided at substantially the center in the length direction and the elastic deformation portions 4 are provided on both sides thereof. A state is obtained.

また、吊具１は、比較的軽量なケーブルＣを適宜間隔をおいて吊持するものに適用されるから、本体部２の弾性復帰力によって両係止部５をデッキプレート３１の両段部３８ｃ間に圧接しアーチ状に横架させた取着状態であっても、吊具１がケーブルＣ及び自身の荷重によってデッキプレート３１から脱落してしまうのを防止することができる。   Further, since the hanging tool 1 is applied to a cable that suspends a relatively lightweight cable C at an appropriate interval, the both locking portions 5 are connected to the two step portions of the deck plate 31 by the elastic return force of the main body portion 2. Even in the attached state in which they are pressed against each other and horizontally arched, the hanging tool 1 can be prevented from falling off the deck plate 31 due to the cable C and its own load.

更には、吊持部３の吊持部材としてバインド線２１が用いられているので、吊具１がケーブルＣの引張り力等によってデッキプレート３１から脱落するのが防止される。即ち、仮に、吊持部材が吊りボルトなどであった場合は、布設作業時等においてケーブルＣが布設方向に引張られたりすると、それにより吊持している吊りボルトが傾動し、その傾動の力が直接本体部に作用して本体部も傾き、係止部が離脱するおそれがある。しかし、本実施形態の吊持部材は変形自在なバインド線２１が用いられているから、ケーブルＣに引張り力等が加わってもその力はバインド線２１により吸収され、本体部２には伝搬しない。したがって、本体部２が傾くのが防止され、上述のように、係止部５がデッキプレート３１の段部３８ｃから離脱して吊具１がデッキプレート３１から脱落してしまうのが防止される。   Furthermore, since the bind wire 21 is used as the suspension member of the suspension portion 3, the suspension tool 1 is prevented from falling off the deck plate 31 due to the tensile force of the cable C or the like. That is, if the suspension member is a suspension bolt or the like, when the cable C is pulled in the laying direction at the time of laying work or the like, the suspended suspending bolt is tilted and the tilting force is tilted. May directly act on the main body part and the main body part may also be inclined, and the locking part may be detached. However, since the deformable binding wire 21 is used in the suspension member of this embodiment, even if a tensile force or the like is applied to the cable C, the force is absorbed by the binding wire 21 and does not propagate to the main body 2. . Therefore, the main body 2 is prevented from being tilted, and as described above, the locking portion 5 is prevented from being detached from the step portion 38c of the deck plate 31 and the hanging tool 1 is prevented from dropping from the deck plate 31. .

加えて、本体部２は全体がデッキプレート３１の凹部空間３６内に入り込むので、本体部２が外部物体との接触によってデッキプレート３１から離脱するのが抑えられる。また、吊持部３のバインド線２１は凹部空間３６の外方においてケーブルＣを吊持可能な長さに設けられているから、凹部空間３６の外方の広いスペースにおいてケーブルＣの結束作業を円滑かつ楽に行なうことができる。   In addition, since the entire main body 2 enters the recessed space 36 of the deck plate 31, the main body 2 can be prevented from being detached from the deck plate 31 due to contact with an external object. Further, since the binding wire 21 of the suspension part 3 is provided in a length that allows the cable C to be suspended outside the recessed space 36, the cable C is bound in a wide space outside the recessed space 36. It can be done smoothly and easily.

ところで、上記実施形態の係止部５は、弾性変形部４の先端側の端部に設けられているが、図１０に示す本体部２のように、弾性変形部４の先端側において幅方向の中央部分を１辺を残してコ字状に切欠して細長の係止片５ａを形成し、その先端部を円弧の凸側方向に折曲形成させて設けたものとすることもできる。この場合、係止部５は、厳密には、本体部２の両端ではなく本体部２の両端側に設けたものとなる。この吊具１をデッキプレート３１に取着すると、図１１に示すように、係止片５ａの先端部に設けられた係止部５は、デッキプレート３１の段部３８ｃに係止するとともに、弾性変形部４の先端側における係止片５ａの外側の外枠部５ｂは、デッキプレート３１の凸条部３８ｂの突出端部に弾性的に当接する。したがって、本体部２は、係止部５に加え、外枠部５ｂにおいてもデッキプレート３１の側壁３８に当接するので、係止部５をより安定して係止させることができる。また、係止部５の係止状態を解除するときは、外枠部５ｂを把持してデッキプレート３１の開口３５の中央側に引張って行なうことができる。なお、図１１において、デッキプレート３１は、天壁３７に２本の円弧突条３７ａが長手方向に沿って並列に形成されており、これと当接する当接部６は本体部２において弾性変形部４の吊持部３側の部分に形成されたものとなる。   By the way, although the latching | locking part 5 of the said embodiment is provided in the edge part of the front end side of the elastic deformation part 4, it is width direction in the front end side of the elastic deformation part 4 like the main-body part 2 shown in FIG. It is also possible to form a slender locking piece 5a by cutting out the central portion of the central portion in a U-shape leaving one side and bending the tip portion in the convex direction of the arc. In this case, strictly speaking, the locking portions 5 are provided not at both ends of the main body 2 but at both ends of the main body 2. When this hanging tool 1 is attached to the deck plate 31, as shown in FIG. 11, the locking portion 5 provided at the tip of the locking piece 5a is locked to the step portion 38c of the deck plate 31, and The outer frame portion 5 b outside the locking piece 5 a on the distal end side of the elastic deformation portion 4 is elastically abutted against the protruding end portion of the protruding strip portion 38 b of the deck plate 31. Accordingly, the main body 2 abuts against the side wall 38 of the deck plate 31 not only in the locking portion 5 but also in the outer frame portion 5b, so that the locking portion 5 can be locked more stably. Further, when the locking state of the locking portion 5 is released, the outer frame portion 5 b can be grasped and pulled toward the center side of the opening 35 of the deck plate 31. In FIG. 11, the deck plate 31 has two arc-shaped ridges 37 a formed in parallel on the top wall 37 along the longitudinal direction, and the abutting portion 6 that abuts on this is deformed elastically in the main body 2. The part 4 is formed on the portion of the suspension part 3 side.

また、上記実施形態の弾性変形部４は、全体的に円弧状に形成されているが、本発明を実施する場合は、これに限られるものではなく、例えば、図１２に示すように、中間部分は直線状に形成され、その両側のみ円弧状に形成されたものとしてもよい。この場合、直線状の中間部分も弾性的に円弧状に撓む。また、弾性変形部４は円弧状に限らず楕円弧状に形成してもよい。更には、弾性変形部４は全体的に直線状に形成し、平面帯状のものとすることを妨げない。この場合、直線状の弾性変形部４は本体部２がデッキプレート３１の凹部空間３６内に嵌入されたときに全体的に円弧状に弾性変形し、弾性復帰力が発生する。   Moreover, although the elastic deformation part 4 of the said embodiment is formed in circular arc shape as a whole, when implementing this invention, it is not restricted to this, For example, as shown in FIG. The portion may be formed in a straight line shape, and only on both sides thereof may be formed in an arc shape. In this case, the linear intermediate portion is also elastically bent into an arc shape. Further, the elastic deformation portion 4 is not limited to an arc shape but may be an elliptic arc shape. Furthermore, the elastically deformable portion 4 is formed in a straight line as a whole, and does not prevent it from being a flat belt. In this case, the linear elastic deformation portion 4 is elastically deformed in an arc shape as a whole when the main body portion 2 is inserted into the recessed space 36 of the deck plate 31, and an elastic restoring force is generated.

そして、上記実施形態の本体部２は、計４本のビード９を設けて係止部５の周辺以外の部分における剛性をやや大きくし、これにより、配線・配管材の揺動や引張りの力等による弾性変形を生じ難くして、係止部５の係合が解除され、吊具１がデッキプレート３１から離脱し落下してしまうのを防止しているが、図１３(a)に示すように、本体部２の幅方向の両端縁部にフランジ１０を設けることにより本体部２の一部の剛性をやや大きくすることもできる。或いは、図１３(b)に示すように、本体部２の一部に板材１１を積層した構造とすることにより剛性をやや大きくすることもできる。   The main body portion 2 of the above embodiment is provided with a total of four beads 9 to slightly increase the rigidity in the portions other than the periphery of the locking portion 5, and thereby the swinging and pulling force of the wiring / pipe material. FIG. 13 (a) shows that it is difficult to cause elastic deformation due to, for example, and the engagement of the locking portion 5 is released and the hanger 1 is detached from the deck plate 31 and dropped. As described above, by providing the flange 10 at both end edges in the width direction of the main body 2, the rigidity of a part of the main body 2 can be slightly increased. Alternatively, as shown in FIG. 13B, the rigidity can be slightly increased by adopting a structure in which the plate member 11 is laminated on a part of the main body 2.

なお、上記実施形態の図８や図１１等において、円盤状の被取付部材８の外径を吊持部３の収納凹部７における対向する一対の側壁面の間隔と略同一寸法に形成すれば、被取付部材８の外周側面が収納凹部７の側壁面と当接し干渉するため、弾性変形部４が逆方向に撓むのが防止され、これにより、弾性変形部４の撓み方向が反転して係止部５の係止状態が解除される方向に弾性変形するのを防止することもできる。   8 and 11 of the above embodiment, the outer diameter of the disk-shaped attached member 8 is formed to be approximately the same as the distance between the pair of opposing side wall surfaces in the storage recess 7 of the suspension portion 3. Since the outer peripheral side surface of the mounted member 8 abuts on and interferes with the side wall surface of the housing recess 7, the elastic deformation portion 4 is prevented from bending in the reverse direction, thereby reversing the bending direction of the elastic deformation portion 4. Thus, elastic deformation in the direction in which the locking state of the locking portion 5 is released can also be prevented.

また、上記実施形態の本体部２は、ステンレス等を使用したバネ鋼材で形成しているが、所要の弾性が得られれば、合成樹脂材で形成してもよい。   Moreover, although the main-body part 2 of the said embodiment is formed with the spring steel material which uses stainless steel etc., as long as required elasticity is obtained, you may form with a synthetic resin material.
