Description

本発明は、デッキプレート上にコンクリートを打設することにより形成される天井面の下方に、吊りバンドを介して被支持体を吊り下げ支持するための吊り下げ支持具において、曲げ加工等が不要で低コストに製造でき、また、下方からの力を受けても吊りバンドが外れにくくするための技術に関する。 The present invention eliminates the need for bending work or the like in a suspension support for supporting a supported body via a suspension band below a ceiling surface formed by placing concrete on a deck plate. The present invention relates to a technique that can be manufactured at low cost and that makes it difficult for the suspension band to come off even when subjected to a force from below.

ビルディング、工場、倉庫、駅舎、その他建造物における空調工事において、空気（新鮮外気、冷気、暖気、排気）を搬送するために重量の大きい亜鉛鉄板製の円形ダクト（スパイラルダクト）が用いられているが、近年、天井吹出し口などに接続する末端のダクトは施工を容易簡略化して工事短縮化を図るため、可撓性に富み、断熱材を装着した軽量のフレキシブルダクトが用いられ、天井のコンクリート面から吊り下げ支持するようにしている。 In air-conditioning work in buildings, factories, warehouses, station buildings, and other buildings, circular ducts (spiral ducts) made of galvanized iron plates that are heavy are used to transport air (fresh outside air, cold air, warm air, exhaust). However, in recent years, the ducts at the end connected to the ceiling outlets, etc. are easily flexible and shorten the work, so they are flexible and lightweight flexible ducts with heat insulating materials are used. It is supported by hanging from the surface.

このようにダクトを天井コンクリート面から吊り下げる方法には、従来では、ダクトの上面に専用の受台を取付け、この受台と天井コンクリートに固定した係止具間を策条で結んで吊り下げする方法（特許文献１）、ダクトを囲む第１の番線の直線状の長さの異なる両端部を、くの字状に中央を曲げた第１の金属板の上下２つの小穴に挿通して両端部を第１の金属板に固定し、コンクリート面から垂下させた直線状の第２の番線の端部と、前記第１の番線の両端部のうちの片方とを、くの字状に中央を曲げた第２の金属板の上下２つの小穴に上下から貫通させて第２の金属板に第１、第２の番線を固定することによって、ダクトを天井コンクリート面から吊り下げ支持する方法（特許文献２）などがあった。 In order to suspend the duct from the ceiling concrete surface in this way, conventionally, a dedicated cradle is attached to the upper surface of the duct, and the cradle and the fasteners fixed to the ceiling concrete are tied together by means of suspending. Method (Patent Document 1), the both ends of the first wire surrounding the duct having different linear lengths are inserted into the upper and lower small holes of the first metal plate bent in the shape of a square. Both ends are fixed to the first metal plate, and the end of the straight second number line suspended from the concrete surface and one of the two end parts of the first number line are formed in a dogleg shape. A method of hanging and supporting a duct from a ceiling concrete surface by passing through two small holes in the upper and lower sides of a second metal plate bent at the center and fixing the first and second wires to the second metal plate. (Patent Document 2).

特開平８−２８５３５９号公報（第２頁、図１）JP-A-8-285359 (2nd page, FIG. 1) 実公昭５８−２５１９３号公報（第４頁、第１図）Japanese Utility Model Publication No. 58-25193 (page 4, Fig. 1)

しかし、前者の方法では、ダクトの上面に予め専用の受台を設けなければならないためコスト高となり、また、後者では２つの金属板に上下から番線の端部を挿通しなければならないため作業が煩雑であった。 However, in the former method, a dedicated cradle must be provided on the upper surface of the duct in advance, resulting in high cost. In the latter method, the end of the number wire must be inserted through the two metal plates from the top and bottom. It was complicated.

また、別の方法として、インサートと吊りボルトを用いる方法があった。即ち、天井面を構成するデッキプレートの穴に上側からインサートを打ち込んでその下部がデッキプレートの下側に露呈するようにしてから、デッキプレートの上側にコンクリートを打設する。コンクリートが固まった後に、インサートの下側に吊りボルトの上端部をネジ込んで固定し、この吊りボルトに吊りバンド支持用の金具を固定し、この金具に吊りバンドの両端を係支させ、吊りバンドの中間部でフレキシブルダクトを包持する。 As another method, there is a method using an insert and a suspension bolt. That is, the insert is driven into the hole in the deck plate constituting the ceiling surface from above so that the lower part is exposed to the lower side of the deck plate, and then concrete is placed on the upper side of the deck plate. After the concrete has hardened, screw the upper end of the suspension bolt into the lower part of the insert and fix it. Fix the suspension band support bracket to the suspension bolt, and support both ends of the suspension band on this bracket. Hold the flexible duct in the middle of the band.

しかし、このインサートと吊りボルトを用いた方法では、（イ）インサートのデッキプレートの穴への打込み、（ロ）インサートへの吊りボルトの取り付け、（ハ）吊りボルトへの金具６の取付け、（ニ）金具への吊りバンドの取付けという４つの作業が必要で、施工に手間がかかり、多大な時間がかかっていた。 However, in this method using the insert and the suspension bolt, (a) driving the insert into the hole in the deck plate, (b) attaching the suspension bolt to the insert, (c) attaching the metal fitting 6 to the suspension bolt, ( D) Four operations of attaching the hanging band to the metal fitting were necessary, and it took time and time for the construction.

これらの問題を解決する方法として、本願出願人は、直線部の上端に抜け防止曲げ部が設けられ、直線部の下端に折り返し部が設けられた線状体からなる吊り下げ支持具を用い、その折り返し部に吊りバンドの両端を係支させ、フレキシブルダクトのような被支持体を天井面の下方に吊り下げ支持する技術を提案している（特許文献３）。 As a method for solving these problems, the applicant of the present application uses a suspension support made of a linear body provided with a bending prevention portion at the upper end of the linear portion and a folded portion at the lower end of the linear portion, A technique has been proposed in which both ends of a suspension band are supported by the folded portion and a supported body such as a flexible duct is suspended and supported below the ceiling surface (Patent Document 3).

しかしながら、特許文献３の吊り下げ支持具においても、製造時に両端の曲げ加工を要する点でコスト高となり、また、その下端側の曲げ加工した部分に係支された吊りバンドが、下方からの力を受けて上方に移動し、その力により曲げ加工した部分が開いて、吊りバンドが外れる場合がある等、さらに解決すべき課題があった。 However, the suspension support of Patent Document 3 is also expensive because it requires bending at both ends during manufacture, and the suspension band supported by the bent portion on the lower end side is forced from below. In response to this, there is a problem to be further solved, such as a case where the bent portion is opened by the force and the suspension band is detached.

本発明は、上記の点を改善して、曲げ加工等をしないで低コストに製造ができ、また、吊りバンドが外れにくい吊り下げ支持具を提供することを目的としている。 An object of the present invention is to provide a suspension support that can improve the above-described points and can be manufactured at low cost without performing bending work and the suspension band is difficult to come off.

In a hanging support for hanging and supporting a supported body via a hanging band below a ceiling surface formed by placing concrete on a deck plate,
It is integrally formed of a metal plate, a strip plate portion, a wide portion for preventing slipping formed wider on the one end side of the strip plate portion than the strip plate portion, and the wide portion from the other end of the strip plate portion. And holding the support plate in a state where the support plate has hook portions formed to be able to pass through the holes provided at both ends of the suspension band and penetrated through the holes leaving the wide portion. Consisting of a bush,
In the middle of the hook portion, there is a width slightly wider than the diameter of the hole provided at both ends of the suspension band, and the direction of expanding the hole of the suspension band by the force applied when engaging the suspension band A disengagement restricting portion is provided that restricts movement of the suspension band in a direction in which the suspension band is disengaged from the hook portion in a state where the hook portion is deformed to pass through and the force is not applied.

このように構成されているため、本発明の吊り下げ支持具は、金属板で一体的に形成され、帯板部と、帯板部の一端側に帯板部より幅広に形成された抜け防止用の幅広部と、帯板部の他端から幅広部側へ延び、吊りバンドの両端に設けられた穴を通過可能に形成されたフック部とを有する平板構造の支持板を用いているので、曲げ加工が不要で低コストに製造でき、フック部の中間に、吊りバンドの両端に設けられた穴の径より僅かに広い幅を有し、吊りバンドを係支する際に与えられる力により吊りバンドの穴を広げる方向に変形させてフック部を通過させ、その力が付与されていない状態で吊りバンドがフック部から外れる方向の移動を規制する外れ規制部が設けられているものでは、吊りバンドの外れ方向の移動が規制されるので、吊りバンドの外れが生じにくくなる。 Because of this configuration, the suspension support of the present invention is integrally formed of a metal plate, and prevents the strip plate portion and the strip plate portion from being formed wider than the strip plate portion on one end side of the strip plate portion. A support plate having a flat structure having a wide portion for use and a hook portion extending from the other end of the band plate portion to the wide portion side so as to be able to pass through holes provided at both ends of the suspension band. It can be manufactured at low cost without the need for bending work, and has a width slightly wider than the diameter of the hole provided at both ends of the suspension band in the middle of the hook portion, and the force applied when engaging the suspension band. In what is provided with a disengagement restricting part that restricts the movement in the direction in which the hanging band is detached from the hook part in a state where the hook part is deformed in a direction to widen the hole of the hanging band and the hook part is passed and the force is not applied Since the movement of the hanging band in the direction of detachment is restricted, Out-of-band is less likely to occur.

また、外れ規制部がフック部の下縁に突設されたストッパにより形成されているものでは、係止されている吊りバンドが下方からの力を受けた場合、その吊りバンドの穴の下端はフック部の下縁に当接して、ストッパの下縁との間に常に段差のある状態となるので、その穴がストッパを超えて外れ方向に移動することができず、吊りバンドの外れはさらに生じにくくなる。 In addition, in the case where the disengagement restricting portion is formed by a stopper protruding from the lower edge of the hook portion, when the suspended hanging band receives a force from below, the lower end of the hole of the hanging band is Since there is always a step between the lower edge of the hook and the lower edge of the stopper, the hole cannot move beyond the stopper in the direction of disengagement. It becomes difficult to occur.

また、デッキプレートの穴に嵌めたブッシュにより支持板を保持する構造の場合、コンクリート打設時の支持板の姿勢変化を防止できる。 In addition, in the case of a structure in which the support plate is held by the bush fitted in the hole of the deck plate, it is possible to prevent a change in the posture of the support plate when placing concrete.

以下、図面に基づいて本発明の実施の形態を説明する。
図１は、デッキプレート上にコンクリートを打設することにより形成される天井面の下方に、吊りバンドを介してフレキシブルダクト等の被支持体を吊り下げ支持するための実施形態の吊り下げ支持具２０を示している。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a suspension support according to an embodiment for supporting a supported body such as a flexible duct under a ceiling surface formed by placing concrete on a deck plate via a suspension band. 20 is shown.

図１に示しているように、この吊り下げ支持具２０は、支持板２１とブッシュ３０により構成されている。 As shown in FIG. 1, the suspension support 20 includes a support plate 21 and a bush 30.

支持板２１は、平板構造で、金属板に対するプレス加工などにより一体的に形成され、上下方向に延びた帯板部２２と、帯板部２２の上端に帯板部２２より幅広に形成された抜け防止用の幅広部２４と、帯板部２２の下端から幅広部２４側へ延び、吊りバンドの両端を係支可能に形成されたフック部２５とを有している。幅広部２４の中央には円形の穴２４ａが設けられている。 The support plate 21 has a flat plate structure and is integrally formed by pressing a metal plate or the like. The support plate 21 extends in the vertical direction, and is formed wider at the upper end of the strip plate portion 22 than the strip plate portion 22. It has a wide portion 24 for preventing slipping, and a hook portion 25 that extends from the lower end of the band plate portion 22 toward the wide portion 24 and is formed so as to be able to support both ends of the suspension band. A circular hole 24 a is provided at the center of the wide portion 24.

ここで、帯板部２２の上部２２ａは一定幅で上下方向に直線状に延び、下部２２ｂは外側に円弧状に湾曲するように形成されている。 Here, the upper part 22a of the band plate part 22 is formed to have a constant width and extend linearly in the vertical direction, and the lower part 22b is formed to be curved outward in an arc shape.

また、フック部２５は、帯板部２２の下端から帯板部２２の長さ方向とほぼ直交する方向に所定距離延びた基部２５ａと、基部２５ａの先端から帯板部２２に沿って幅広部２４方向（上方）に延びた折り返し部２５ｂとを有している。 The hook portion 25 includes a base portion 25a extending from the lower end of the strip plate portion 22 by a predetermined distance in a direction substantially orthogonal to the length direction of the strip plate portion 22, and a wide portion extending along the strip plate portion 22 from the tip of the base portion 25a. And a folded portion 25b extending in 24 directions (upward).

基部２５ａの上下方向の幅（高さ）Ｈ１は、後述する吊りバンド１０の両端に設けられた穴１１、１２の吊りバンドの長さ方向に沿った径より小さく設定されていて、その穴を通過できる。また、折り返し部２５ｂの水平方向の幅は、吊りバンドの両端に設けられた穴を通過できるように設定されている。 The vertical width (height) H1 of the base portion 25a is set to be smaller than the diameter along the length direction of the suspension bands of holes 11 and 12 provided at both ends of the suspension band 10 to be described later. I can pass. The horizontal width of the folded portion 25b is set so that it can pass through holes provided at both ends of the suspension band.

さらに、帯板部２２の側縁と折り返し部２５ｂの側縁との間に縦長に形成される上方が開口された隙間２６の幅Ｗは、吊りバンドの厚さの２倍より大（例えば４倍程度）となるように設定されている。 Further, the width W of the gap 26 that is vertically formed between the side edge of the band plate portion 22 and the side edge of the folded portion 25b is larger than twice the thickness of the suspension band (for example, 4 Is set to be approximately twice as high).

また、折り返し部２５ｂの下端には基部２５ａの下縁より僅かに下方に突出するストッパ２５ｃが設けられている。基部２５ａの上縁と折り返し部２５ｂの左縁とが交わる位置からストッパ２５ｃの下端までの部分は、この実施形態の外れ規制部を構成するものであり、その幅Ｈ２は、吊りバンドの穴の長さより僅かに長くなるように設定されている。 Further, a stopper 25c is provided at the lower end of the folded portion 25b so as to protrude slightly downward from the lower edge of the base portion 25a. The portion from the position where the upper edge of the base portion 25a and the left edge of the folded portion 25b intersect to the lower end of the stopper 25c constitutes the disengagement restricting portion of this embodiment, and its width H2 is the width of the hole of the suspension band It is set to be slightly longer than the length.

したがって、吊りバンドの穴に、折り返し部２５ｂを通し、さらに基部２５ａまで通そうとすると、このストッパ２５ｃに引っかかって通過できないが、吊りバンドは合成樹脂製で可撓性を有しているので、下方に強く引き下げると、穴が拡がる方向に変形してこのストッパ２５ｃを通過し、基部２５ａまで通すことができる。そしてストッパ２５ｃを通過した後に、下方へ強い力を与えなければ吊りバンドの穴がストッパ２５ｃを超えて折り返し部２５ｂ側へ戻ることはできず、吊りバンドの外れは起こらない。 Therefore, if you try to pass the folded portion 25b through the hole of the suspension band and further to the base portion 25a, it will be caught by this stopper 25c and cannot pass, but the suspension band is made of synthetic resin and has flexibility, When pulled down downward, the hole can be deformed in the direction in which it expands, pass through the stopper 25c, and pass to the base 25a. After passing through the stopper 25c, unless a strong force is applied downward, the hole of the suspension band cannot return to the folded portion 25b side beyond the stopper 25c, and the suspension band does not come off.

一方、ブッシュ３０はゴムなどの弾性変形材で形成され、図３、図４に示すようにデッキプレート１の円形の穴１ａに嵌め込まれた状態で支持板２１を保持する。 On the other hand, the bush 30 is formed of an elastically deformable material such as rubber, and holds the support plate 21 in a state of being fitted into the circular hole 1a of the deck plate 1 as shown in FIGS.

即ち、ブッシュ３０は、図１、図２に示しているように、穴１ａより小径の円板状でデッキプレート１とほぼ等しい厚さを有する基部３１と、基部３１の上部に同心状に設けられ、穴１ａより大径の略円板状に形成された鍔部３２と、基部３１の下部に同心状に設けられ、基部３１寄りの径が穴１ａの径より大で、基部３１から離間する程径が小さくなり、先端の径が穴１ａの径より小となる切頭逆円錐状のテーパ部３３とを有しており、その中心部には、支持板２１の帯板部２２およびフック部２５を通過させ且つ幅広部２４の通過を阻止する穴３４が、上下方向に貫通するように形成されている。また、鍔部３２の下面側外縁には、リブ３２ａが環状に突設されている。 That is, as shown in FIGS. 1 and 2, the bush 30 is concentrically provided on a base 31 having a disk shape smaller in diameter than the hole 1 a and having a thickness substantially equal to that of the deck plate 1, and on the upper part of the base 31. The flange 32 is formed in a substantially disc shape having a larger diameter than the hole 1a, and is concentrically provided at the lower portion of the base 31. The diameter near the base 31 is larger than the diameter of the hole 1a and is spaced from the base 31. And a tapered portion 33 having a truncated inverted conical shape whose tip diameter is smaller than the diameter of the hole 1a, and the band plate portion 22 of the support plate 21 and A hole 34 that allows the hook portion 25 to pass therethrough and prevents the wide portion 24 from passing therethrough is formed so as to penetrate vertically. In addition, a rib 32 a is provided in a ring shape on the outer edge on the lower surface side of the flange portion 32.

また、この穴３４の開口の幅と高さは、支持板２１の帯板部２２の上部の幅と厚さよりそれぞれ僅かずつ小となるように設定され、支持板２１が挿着されたとき穴３４が僅かに拡がるように弾性変形し、その復帰力で帯板部２２の上部外周に密着して隙間を生じさせないようになっている。 Further, the width and height of the opening of the hole 34 are set so as to be slightly smaller than the width and thickness of the upper portion of the band plate portion 22 of the support plate 21, respectively. When the support plate 21 is inserted, the hole is formed. 34 is elastically deformed so that it slightly expands, and the return force closely contacts the outer periphery of the upper portion of the band plate portion 22 so as not to generate a gap.

前記支持板２１とブッシュ３０からなる吊り下げ支持具２０を使用する場合、支持板２１をブッシュ３０の穴３４に挿着した状態でデッキプレート１の穴１ａに嵌め込む方法と、予めデッキプレート１の穴１ａにブッシュ３０を嵌め込み、その後にブッシュ３０の穴３４に支持板２１を挿着する方法のいずれでもよい。 When using the suspension support 20 including the support plate 21 and the bush 30, a method of fitting the support plate 21 into the hole 1 a of the deck plate 1 in a state where the support plate 21 is inserted into the hole 34 of the bush 30, and the deck plate 1 in advance. Any method may be used in which the bush 30 is fitted into the hole 1a and the support plate 21 is inserted into the hole 34 of the bush 30 thereafter.

ブッシュ３０を先にデッキプレート１に嵌め込む場合には、図３に示しているように、デッキプレート１の穴１ａに上方からテーパ部３３の先端側を挿入して押し込み、テーパ部３３の基部３１寄りの外縁を弾性変形させながら進入させ、テーパ部３３全体が穴１ａを通過した状態にする。この段階でテーパ部３３の外縁が弾性復帰し、図４に示しているように、鍔部３２との間で穴１ａの周縁を挟んだ状態、即ち、抜けない状態で固定される。また、この状態で、鍔部３２の下面側のリブ３２ａがデッキプレート１の穴１ａの周りに強く当接して、鍔部３２とデッキプレート１の上面との間に隙間を生じさせないようになっている。 When the bush 30 is first fitted into the deck plate 1, as shown in FIG. 3, the distal end side of the taper portion 33 is inserted and pushed into the hole 1 a of the deck plate 1 from above, and the base portion of the taper portion 33 is inserted. The outer edge close to 31 is made to enter while being elastically deformed, so that the entire tapered portion 33 passes through the hole 1a. At this stage, the outer edge of the tapered portion 33 is elastically restored, and as shown in FIG. 4, the outer periphery of the hole 1a is sandwiched between the flange portion 32, that is, fixed in a state where it does not come off. Further, in this state, the rib 32a on the lower surface side of the flange portion 32 strongly abuts around the hole 1a of the deck plate 1 so that no gap is generated between the flange portion 32 and the upper surface of the deck plate 1. ing.

そして、このブッシュ３０の穴３４に上方から支持板２１を下端のフック部２５側から挿入し、幅広部２４の下端と穴３４の上端とが当接するまで押し込む。 Then, the support plate 21 is inserted into the hole 34 of the bush 30 from above from the hook part 25 side at the lower end, and is pushed in until the lower end of the wide part 24 and the upper end of the hole 34 abut.

この作業により、図４に示しているように、穴１ａに隙間がない状態（コンクリート打設時のコンクリート材の漏れを防止できる状態）で、支持板２１を、そのフック部２５がデッキプレート１の下面側に突出し、幅広部２４がデッキプレート１の上面側に突出した状態で、デッキプレート１の穴１ａに挿着することができる。 As a result of this operation, as shown in FIG. 4, the support plate 21 and the hook portion 25 of the deck plate 1 have the hook plate 25 in a state where there is no gap in the hole 1 a (a state in which leakage of the concrete material during concrete placement can be prevented). It can be inserted into the hole 1a of the deck plate 1 with the wide portion 24 protruding to the upper surface side of the deck plate 1.

そして、図４に示しているように、デッキプレート１の上面側にコンクリート３を打設し、養生することで、支持板２１の幅広部２４がコンクリート３に埋設されて、支持板２１が天井面に固定される。 Then, as shown in FIG. 4, by placing concrete 3 on the upper surface side of the deck plate 1 and curing, the wide portion 24 of the support plate 21 is embedded in the concrete 3, and the support plate 21 is attached to the ceiling. Fixed to the surface.

ここで、コンクリート３は支持板２１の幅広部２４の周囲だけでなく、幅広部２４の穴２４ａを埋めるように流れて固まるので、支持板２１は堅固に固定される。また、支持板２１はブッシュ３０に保持された状態で穴１ａに挿着されているので、コンクリート打設時の衝撃等による傾きや、軸周りの回転が抑制され、ほぼ垂直状態で所望の向きの状態で固定される。 Here, since the concrete 3 flows and hardens so as to fill not only the periphery of the wide portion 24 of the support plate 21 but also the hole 24a of the wide portion 24, the support plate 21 is firmly fixed. Further, since the support plate 21 is inserted into the hole 1a while being held by the bush 30, tilting due to an impact or the like at the time of placing concrete and rotation around the axis are suppressed, and a desired orientation is obtained in a substantially vertical state. It is fixed in the state.

そして、この状態で図５に示しているように、被支持体を包持するための吊りバンド１０の一端側１０ａの穴１１にフック部２５の折り返し部２５ｂを通過させ、穴１１の上端が基部２５ａの上端に達して下端がストッパ２５ｃに当接する位置に引き下げる。なお、ここでは、吊りバンド１０の穴１１がその長さ方向に沿った長軸をもつ長円形穴としているが、長方形、円形などであってもよい。ただし、バンドの長さ方向に沿った長さＬが最大となることが望ましい。 In this state, as shown in FIG. 5, the folded portion 25 b of the hook portion 25 is passed through the hole 11 on the one end side 10 a of the suspension band 10 for holding the supported body, and the upper end of the hole 11 is The upper end of the base portion 25a is reached and the lower end is pulled down to a position where it comes into contact with the stopper 25c. Here, the hole 11 of the suspension band 10 is an oval hole having a long axis along the length direction thereof, but may be a rectangle, a circle, or the like. However, it is desirable that the length L along the length direction of the band is maximized.

前記したように、折り返し部２５ｂの幅は穴１１の長さＬより小さいので、折り返し部２５ｂは穴１１を通過するが、基部２５ａの上端からストッパ２５ｃの下端までの距離Ｈ２は穴１１の長さＬより僅かに長いので、そのまま通過することはできない。 As described above, since the width of the folded portion 25b is smaller than the length L of the hole 11, the folded portion 25b passes through the hole 11, but the distance H2 from the upper end of the base portion 25a to the lower end of the stopper 25c is the length of the hole 11. Since it is slightly longer than the length L, it cannot pass as it is.

しかし、前記したように吊りバンド１０を少し強い力で引き下げると、その穴１１の上縁と下縁が穴径を拡げる方向に弾性変形しストッパ２５ｃを通過して、図６のように、基部２５ａが吊りバンド１０の一端１０ａの穴１１に挿通した状態となる。ストッパ２５ｃを通過した後、下方への力の付与を停止すれば、穴１１の径は元の状態に復帰するので、ストッパ２５ｃを外れ方向に通過することはできない。 However, when the suspension band 10 is pulled down with a slightly strong force as described above, the upper and lower edges of the hole 11 are elastically deformed in the direction of expanding the hole diameter and pass through the stopper 25c, as shown in FIG. 25a is in a state of being inserted into the hole 11 at the one end 10a of the suspension band 10. If the application of the downward force is stopped after passing through the stopper 25c, the diameter of the hole 11 returns to the original state, so that it cannot pass through the stopper 25c.

次に、図６に示しているように、例えば被支持体としてフレキシブルダクト１５を吊りバンド１０の中間部で包持し、前記同様に吊りバンド１０の他端１０ｂの穴１２にフック部２５の折り返し部２５ｂを通過させ、吊りバンド１０を強く引き下げてストッパ２５ｃを通過させ、基部２５ａが穴１２を挿通する状態にする。 Next, as shown in FIG. 6, for example, a flexible duct 15 is held as an object to be supported by an intermediate portion of the suspension band 10, and the hook portion 25 is inserted into the hole 12 of the other end 10 b of the suspension band 10 as described above. The folded portion 25b is passed, the suspension band 10 is pulled down strongly, and the stopper 25c is passed, so that the base portion 25a is inserted through the hole 12.

この作業により、図７のように、吊りバンド１０の両端１０ａ、１０ｂは互いに重なり合った状態で帯板部２２と折り返し部２５ｂの間に挟まれ、且つ外れ方向の移動が規制された状態で係支される。 By this operation, as shown in FIG. 7, both ends 10a and 10b of the suspension band 10 are sandwiched between the band plate portion 22 and the folded portion 25b while being overlapped with each other, and the movement in the disengagement direction is restricted. Be supported.

この状態で、フレキシブルダクト１５や吊りバンド１０に下方から力が加わっても、吊りバンド１０の穴１１、１２の下縁がフック部２５の基部２５ａの下縁に当接し、ストッパ２５ｃの下端との間に段差がある状態が維持されるため、吊りバンド１０の両端がフック部２５から外れる方向に移動することはできず、吊りバンド１０の外れは発生しない。 In this state, even if force is applied to the flexible duct 15 and the suspension band 10 from below, the lower edges of the holes 11 and 12 of the suspension band 10 abut against the lower edge of the base portion 25a of the hook portion 25, and the lower end of the stopper 25c Therefore, both ends of the suspension band 10 cannot move in a direction away from the hook portion 25, and the suspension band 10 does not come off.

このように実施形態の吊り下げ支持具２０は、曲げ加工などが不要な平板構造の支持板２１を用いているので低コストに製造でき、少ない工数で吊りバンド１０を介してダクトなどの被支持体を容易に吊り下げ支持でき、被支持体が多い場合でも低コストに工事できる。また、フック部２５の中間部の下縁に突設したストッパ２５ｃにより外れ規制部を形成しているので、下方からの力で吊りバンド１０が外れるという問題も解消される。 As described above, the suspension support 20 of the embodiment uses the support plate 21 having a flat plate structure that does not require bending work, and thus can be manufactured at a low cost, and can support a duct or the like via the suspension band 10 with less man-hours. The body can be easily suspended and supported, and construction can be performed at low cost even when there are many supported bodies. Further, since the disengagement restricting portion is formed by the stopper 25c projecting from the lower edge of the intermediate portion of the hook portion 25, the problem that the hanging band 10 is disengaged by a force from below is also solved.

また、前記したように帯板部２２と折り返し部２５ｂとの隙間Ｗは、吊りバンド１０の厚さの２倍より十分広く、しかも、吊りバンド１０の穴１１、１２の横幅（バンドの長手方向と直交する方向の幅）が支持板２１の厚さより大であるので、吊りバンド１０はフック部２５に係支された状態で比較的広い範囲内を捩れ方向に回動できる。また、吊りバンド１０自体の可撓性により捩れ変形できる。 Further, as described above, the gap W between the band plate portion 22 and the folded portion 25b is sufficiently wider than twice the thickness of the suspension band 10, and the lateral width of the holes 11 and 12 of the suspension band 10 (the longitudinal direction of the band) Is wider than the thickness of the support plate 21, the suspension band 10 can be rotated in a twisted direction within a relatively wide range while being supported by the hook portion 25. Moreover, it can be twisted and deformed by the flexibility of the suspension band 10 itself.

したがって、図８に示しているように吊りバンド１０を例えば９０°捩じった状態で支持することも可能であり、この吊りバンド１０の捩れにより、支持板２１の向きと支持対象のフレキシブルダクト１５の長さ方向をあまり気にすることなく工事を行える。 Therefore, as shown in FIG. 8, it is possible to support the suspension band 10 in a state twisted by 90 °, for example, and the twist of the suspension band 10 causes the orientation of the support plate 21 and the flexible duct to be supported. Work can be done without worrying about the 15 length direction.

前記実施形態では、コンクリート打設時のコンクリート材の漏れを防ぐとともに、支持板２１の傾きや軸周りの回転を防ぐためにブッシュ３０を用いていたが、前記したように、支持板２１に係止される吊りバンド１０の姿勢には捩れ方向を含む自由度があるので、支持板２１に対する保持機能を持たないもの、例えば、デッキプレート１の穴１ａを塞ぐテープ類等で代用することもできる。 In the above embodiment, the bush 30 is used to prevent the leakage of the concrete material at the time of placing the concrete and to prevent the inclination of the support plate 21 and the rotation around the axis. However, as described above, the bushing is locked to the support plate 21. Since the posture of the hanging band 10 has a degree of freedom including the twisting direction, it can be substituted by a tape that does not have a holding function for the support plate 21, for example, a tape that closes the hole 1 a of the deck plate 1.

また、デッキプレート１に設ける穴１ａの形状を、支持板２１の帯板部２２を通過させ、幅広部２４の通過を阻止する大きさの長穴にすることができる場合には、ブッシュやテープ等を用いずに、図９のように、支持板２１をデッキプレート１の穴１ａに挿着した状態で、コンクリートを打設して支持板２１を固定し、その支持板２１のフック部２５に係支した吊りバンド１０でフレキシブルダクト１５を支持することもできる。また、穴１ａの形状に限らず、コンクリート材の漏れが問題にならない場合にも、このブッシュなどを用いない方法を採用できる。 If the shape of the hole 1a provided in the deck plate 1 can be a long hole having a size that allows the band plate portion 22 of the support plate 21 to pass therethrough and prevents the wide portion 24 from passing therethrough, a bush or tape is used. 9, with the support plate 21 inserted into the hole 1 a of the deck plate 1 as shown in FIG. 9, concrete is placed to fix the support plate 21, and the hook portion 25 of the support plate 21 is fixed. The flexible duct 15 can also be supported by the suspension band 10 that is attached to and supported by. Further, not only in the shape of the hole 1a, but also in a case where leakage of the concrete material does not become a problem, a method that does not use this bush or the like can be employed.

なお、支持板２１およびブッシュ３０の形状は上記実施形態に限定されるものでなく、種々変形可能である。例えば、図１０に示す支持板２１のように、帯板部２２およびフック部２５の外縁をほぼ直線状に形成してもよい。この支持板２１においても、フック部２５の基部２５ａの高さ（縦方向幅）と折り返し部２５ｂの幅（横方向幅）を吊りバンド１０の穴１１、１２の内径より小さくし、基部２５ａの上端からストッパ２５ｃの下端までの距離Ｈ２を吊りバンド１０の穴１１、１２の内径より僅かに大きくして、吊りバンド１０の外れを防ぐ。 In addition, the shape of the support plate 21 and the bush 30 is not limited to the said embodiment, A various deformation | transformation is possible. For example, like the support plate 21 shown in FIG. 10, the outer edges of the band plate portion 22 and the hook portion 25 may be formed substantially linearly. Also in the support plate 21, the height (vertical width) of the base portion 25 a of the hook portion 25 and the width (lateral width) of the folded portion 25 b are made smaller than the inner diameters of the holes 11 and 12 of the suspension band 10. The distance H2 from the upper end to the lower end of the stopper 25c is made slightly larger than the inner diameters of the holes 11 and 12 of the suspension band 10 to prevent the suspension band 10 from coming off.

また、上記実施形態では、吊りバンドに下方から上方へ力が加わったときの外れを確実に防止できるように、フック部２５の中間部の下縁にストッパ２５ｃを突設して外れ規制部を形成していたが、フック部の中間部であれば、外れ規制部を設ける位置は任意であり、例えば基部２５ａの途中や折り返し部２５ｂの途中に吊りバンド１０の穴１１、１２の内径より幅の広い部分を外れ規制部として設けることもできる。ただし折り返し部２５ｂの途中に外れ規制部を設けた場合、下方からの所定以下の力で吊りバンドの穴が外れ規制部を通過しないように、外れ規制部の幅を増しておく必要があり、その場合には、吊りバンドを係支する際にもより強い力を要することになる。 Further, in the above embodiment, the stopper 25c is protruded from the lower edge of the intermediate portion of the hook portion 25 so as to prevent the detachment when the force is applied to the suspension band from below to above. Although it is formed, the position where the disengagement restricting portion is provided is arbitrary as long as it is an intermediate portion of the hook portion. For example, it is wider than the inner diameters of the holes 11 and 12 of the suspension band 10 in the middle of the base portion 25a and the folded portion 25b It is also possible to provide a wide part as a restricting part. However, when a disengagement restricting portion is provided in the middle of the folded portion 25b, it is necessary to increase the width of the disengagement restricting portion so that the hole of the suspension band does not come off and pass through the restricting portion with a predetermined force from below. In that case, a stronger force is required when the suspension band is supported.
