Description

この発明は、例えば仮設足場のコーナ部における互いに直交し合う水平材間に跨る状態で火打ち部材の両端部を該水平材に取り付ける用に適した取付け具に関する。 The present invention relates to a fitting suitable for attaching both end portions of a fire striking member to a horizontal member in a state of straddling between mutually orthogonal horizontal members in a corner portion of a temporary scaffold, for example.

比較的低層の建築物の外足場として、一側足場が多く使用されているが、このような一側足場のコーナー部においては、そのコーナー部の互いに直交し合う鉄製パイプのような水平材間に鉄製パイプのような火打ち部材を架け渡して補強するのが通例である。 One side scaffolding is often used as an external scaffolding for relatively low-rise buildings, but in the corner part of such one side scaffolding, there is a space between horizontal members such as iron pipes that intersect each other at right angles. It is customary to reinforce a fire-fighting member such as an iron pipe.

このような火打ち部材の端部を水平材に取り付ける取付け具として、一般には、クランプ金具を使用することが多かったが、このクランプ金具を使用する場合、ボルト締めによってクランプ金具を水平材に連結しなければならず、作業が面倒であった。 In general, a clamp fitting is often used as a fixture for attaching the end of such a fire-fitting member to a horizontal member. However, when using this clamp fitting, the clamp fitting is connected to the horizontal piece by bolting. It had to be troublesome.

ボルト締めのような面倒な作業をなくすために、従来、取付け具として、挟持金具に突設された挟持片と、挟持金具における楔ガイドに挿入された楔部材とで水平材を挟み込むようした技術が知られている（例えば、特許文献１参照）。
特開２００２−３７１７０７号公報 In order to eliminate troublesome work such as bolt tightening, conventionally, as a mounting tool, a technique in which a horizontal member is sandwiched between a clamping piece protruding from a clamping bracket and a wedge member inserted into a wedge guide in the clamping bracket Is known (see, for example, Patent Document 1).
JP 2002-371707 A

しかし、前記した公知技術においては、楔部材の斜面が長さ方向の先端から基端まで一つの斜面で構成されているから、楔部材の長さを、例えば水平材の径が大きい場合に対応して設定してあると、水平材の径が小さい場合には、楔部材の長さ不足で必要な打ち込み量が得られないおそれがある。このため、径の異なる水平材に対応させためには、楔部材の長さを過度に大きくすることも考えられるが、それでは扱い難くなり、実用的ではない。 However, in the above-described known technique, since the slope of the wedge member is composed of one slope from the distal end to the base end in the length direction, the length of the wedge member can be adjusted, for example, when the diameter of the horizontal member is large. If the diameter of the horizontal member is small, there is a possibility that the necessary driving amount cannot be obtained due to the insufficient length of the wedge member. For this reason, in order to cope with horizontal members having different diameters, it is conceivable to excessively increase the length of the wedge member, but this makes it difficult to handle and is not practical.

この発明は、楔部材を過度に長くしたりしなくても、棒材の径の変更に対応して適正な取り付けが行える取付け具を提供することを課題とする。 This invention makes it a subject to provide the fixture which can be attached appropriately according to the change of the diameter of a bar, without making a wedge member too long.

前記楔部材３は、例えば剛性金属板等からなる細長の板状基部３１と、この板状基部３１の幅方向両端にそれぞれ一体に形成された前後一対の対向壁部３２，３３とにより横断面形状が略Ｕ字形に形成されており、前記一対の対向壁部３２，３３の各先端面３２ａ，３３ａは、楔作用に司る圧接用斜面として構成されている。 The wedge member 3 has a transverse cross section composed of an elongated plate-like base portion 31 made of, for example, a rigid metal plate and a pair of front and rear opposing wall portions 32 and 33 integrally formed at both ends of the plate-like base portion 31 in the width direction. The shape is substantially U-shaped, and the tip surfaces 32a, 33a of the pair of opposing wall portions 32, 33 are configured as pressure contact inclined surfaces that control wedge action.

つまり、水平材２００に前記取付け具本体１における外嵌孔部１４，１５を外嵌した状態で、取付け具本体１における打ち込み用開通部１９に前記楔部材３を矢印Ｑ方向に沿って挿入して打ち込んだ際、楔部材３の板状基部３１が取付け具本体１における第１および第２スペーサ部材１６，１７で規制される一方、前記対向壁部３２，３３の各先端面３２ａ，３３ａで水平材２００が押圧されて抜け止めされるようになっている。 That is, the wedge member 3 is inserted along the arrow Q direction into the driving opening 19 in the fixture body 1 with the outer fitting holes 14 and 15 in the fixture body 1 being fitted on the horizontal member 200. The plate-like base portion 31 of the wedge member 3 is regulated by the first and second spacer members 16 and 17 in the fixture body 1 while being driven by the front end surfaces 32a and 33a of the opposing wall portions 32 and 33. The horizontal member 200 is pressed and prevented from coming off.

この楔部材３における対向壁部３２，３３の各先端面３２ａ，３３ａは、長さ方向の先端から基端までの間で径の異なる水平材２００に対応して複数の段階に分けて構成されている。この例においては、対向壁部３２，３３の先端面３２ａ，３３ａの長さ方向における略中央部に段差３ｂが形成されており、その差部３ｂを境にしてそれよりも先端側が径の大きい水平材２００に対応する圧接用斜面３ａとして設定され、段差３ｂよりも基端側が径の小さい水平材２００に対応する圧接用斜面３ｃとして２段階に分けて構成されている。 The front end surfaces 32a and 33a of the opposing wall portions 32 and 33 in the wedge member 3 are divided into a plurality of stages corresponding to the horizontal member 200 having a different diameter from the front end to the base end in the length direction. ing. In this example, a step 3b is formed at a substantially central portion in the length direction of the front end surfaces 32a and 33a of the opposing wall portions 32 and 33, and the front end side is larger in diameter than the difference 3b. The pressure contact slope 3a corresponding to the horizontal member 200 is set in two stages as the pressure contact slope 3c corresponding to the horizontal member 200 having a smaller diameter on the base end side than the step 3b.

楔部材３における板状基部３１には、長さ方向の先端部付近から基端部付近までの間に、楔部材３の脱落阻止用のコ字形金具４１が貫通可能な長孔３４が形成されている。 The plate-like base portion 31 of the wedge member 3 is formed with a long hole 34 through which the U-shaped fitting 41 for preventing the wedge member 3 from dropping can be inserted between the vicinity of the longitudinal end portion and the vicinity of the base end portion. ing.

この金具４１は、例えば金属棒材からなる基体４１ａの長さ方向の両端部を係止片部４１ｂ，４１ｃとして直角に折曲したものであり、長孔３４に挿通した状態で、両係止片部４１ｂ，４１ｃの各先端面が前記スペーサ部材１８，１７の各外周面に溶接等で固定されている。従って楔部材３を打ち込み用開通部１９への打ち込み方向Ｑに対する進退動作を許容しつつ、楔部材３が抜け出し方向（後退方向）に移動した際には、楔部材３の基部３１がコ字形金具４１に係止することににより、楔部材３が取付け具本体１から不用意に脱落するのが防止されるようになっている。本実施形態においては、コ字形金具４１と、前記楔部材３における長孔３４とで楔部材３の脱落阻止手段４が構成されている。 The metal fitting 41 is formed by bending both ends in the length direction of the base body 41a made of, for example, a metal bar at right angles as locking pieces 41b and 41c. The tip surfaces of the pieces 41b and 41c are fixed to the outer peripheral surfaces of the spacer members 18 and 17 by welding or the like. Therefore, when the wedge member 3 moves in the withdrawal direction (retracting direction) while allowing the wedge member 3 to move forward and backward in the driving direction Q to the driving opening portion 19, the base 31 of the wedge member 3 is a U-shaped bracket. The wedge member 3 is prevented from inadvertently dropping from the fixture main body 1 by being locked to 41. In the present embodiment, the U-shaped fitting 41 and the elongated hole 34 in the wedge member 3 constitute the wedge member 3 drop-off preventing means 4.

つぎに、上記構成の取付け具１０を用いて火打ち部材１０１を仮設足場Ａにおける互いに直交し合う水平材２００，２００に架け渡して固定する手順を説明する。 Next, a procedure for spanning and fixing the firing member 101 on the horizontal members 200 and 200 in the temporary scaffold A that are orthogonal to each other using the fixture 10 having the above-described configuration will be described.

まず、前記火打ち部材本体１００の両端に取付け具１０が取り付けられた火打ち部材１０１を、取付け具１０を介して水平材２００，２００に架け渡すように配置する。なお、ここでは、説明の簡易化上、一方の水平材２００に火打ち部材本体１００の一端部を固定する場合のみで説明する。 First, the fire-thinning member 101 having the fixture 10 attached to both ends of the flame-striking member main body 100 is arranged so as to be bridged over the horizontal members 200, 200 via the fixture 10. Here, for simplification of description, only the case where one end portion of the firing member main body 100 is fixed to one horizontal member 200 will be described.

まず、取付け具本体１における前後一対の二股片部１１，１２の各外嵌孔部１４，１５を図３〜図５に示すように、水平材２００に嵌合させる。ついで、前記取付け具本体１における二股片部１１，１２間における楔部材打ち込み用開通部１９に対して図６および図７に示すように、前記楔部材３の先端側を挿入してから打ち込む。 First, the outer fitting hole portions 14 and 15 of the pair of front and rear bifurcated piece portions 11 and 12 in the fixture main body 1 are fitted into the horizontal member 200 as shown in FIGS. Next, as shown in FIG. 6 and FIG. 7, the wedge member 3 is driven after being inserted into the wedge member driving opening portion 19 between the bifurcated piece portions 11, 12 of the fixture body 1.

前記楔部材３を打ち込むと、その板状基部３１が嵌合方向において前記第１および第２スペーサ部材１６、１７で規制されるから、その斜面３２ａ，３３ａにより前記水平材２００が嵌合方向へ押圧され、該水平材２００が前記二股片部１１，１２の各外嵌孔部１４，１５の各奥端面に圧接される。つまり、楔部材３の打ち込みによって、水平材２００の外周面と前記スペーサ部材１６，１７とに対する楔効果が発揮されて水平材２００が取付け具本体１に抜け止めされる。 When the wedge member 3 is driven, the plate-like base portion 31 is regulated by the first and second spacer members 16 and 17 in the fitting direction, so that the horizontal member 200 is moved in the fitting direction by the inclined surfaces 32a and 33a. When pressed, the horizontal member 200 is brought into pressure contact with the back end surfaces of the outer fitting hole portions 14 and 15 of the bifurcated piece portions 11 and 12. That is, by driving the wedge member 3, a wedge effect is exerted on the outer peripheral surface of the horizontal member 200 and the spacer members 16, 17, and the horizontal member 200 is prevented from being detached from the fixture body 1.

ところで、前記楔部材３の対向壁部３２，３３の各先端面３２ａ，３３ａがそれぞれ長さ方向で一つの斜面だけで構成されていると、水平材２００の径が異なる場合、打ち込み量不足等で十分な楔効果が発揮されないおそれもある。このため、楔部材３の斜面長を、水平材２００の径の違いに対応できるように長く設定することも考えられるが、その場合、楔部材３の長さが前記打ち込み方向における取付け具本体１の幅に対して過度に大きくなり、扱い難くくなり、実用的ではない。 By the way, if the front end surfaces 32a and 33a of the opposing wall portions 32 and 33 of the wedge member 3 are each composed of only one inclined surface in the length direction, when the diameter of the horizontal member 200 is different, the driving amount is insufficient. However, there is a possibility that a sufficient wedge effect may not be exhibited. For this reason, it is conceivable that the slope length of the wedge member 3 is set to be long so as to correspond to the difference in the diameter of the horizontal member 200. In this case, the length of the wedge member 3 is set to the fixture main body 1 in the driving direction. It becomes excessively large with respect to the width of the sheet, becomes difficult to handle, and is not practical.

これに対して、上記した楔部材３では、前記対向壁部３２，３３の各先端面３２ａ，３３ａが長さ方向で２段階に分けられた斜面３ａ，３ｃで構成されているから、楔部材３の長さを過度に長く設定しなくても、径の異なる水平材２００に対応させることが可能となる。 On the other hand, in the wedge member 3 described above, the front end surfaces 32a and 33a of the opposing wall portions 32 and 33 are constituted by slopes 3a and 3c divided in two stages in the length direction. Even if the length of 3 is not set excessively long, it becomes possible to correspond to the horizontal member 200 having a different diameter.

例えば、水平材２００の径が比較的小さい場合には、図６に示すように楔部材３の打ち込み量が大きいから、楔部材３の段差３ｂよりも基端側の斜面３ｃで水平材２００が圧接される。逆に、水平材２００の径が比較的大きい場合には、図８に示すように、楔部材３の打ち込み量が小さいから、楔部材３の段差３ｂよりも先端側の斜面３ａで水平材２００が圧接されることになる。勿論、楔部材３の斜面３２ａ，３３ａは、楔部材３の長さ方向の略中央の段差３ｂを境にして２段の斜面３ａ，３ｃで構成されるものに限らず、更に斜面段数を増やしたものであってもよい。 For example, when the diameter of the horizontal member 200 is relatively small, the amount of driving of the wedge member 3 is large as shown in FIG. 6, so that the horizontal member 200 is located on the slope 3c on the base end side with respect to the step 3b of the wedge member 3. Press contact. On the contrary, when the diameter of the horizontal member 200 is relatively large, as shown in FIG. 8, since the driving amount of the wedge member 3 is small, the horizontal member 200 is located on the inclined surface 3 a on the tip side of the step 3 b of the wedge member 3. Will be pressed. Needless to say, the slopes 32a and 33a of the wedge member 3 are not limited to the slopes 3a and 3c having two steps with the step 3b at the substantially center in the length direction of the wedge member 3 as a boundary. It may be.

また本実施形態においては、楔部材３の長孔３４に挿入されたコ字形金具４１が、取付け具本体１に固定されているため、不用意に楔部材３が打ち込み用開通部１９から後退することがあっても、図８の鎖線で示すように楔部材３がコ字形金具４１で係止されるので、楔部材３が取付け具本体１から脱落したりするのが防止される。勿論、この楔部材３の脱落阻止手段４としては、このコ字形金具４１を用いるものに限らず、各種の係止構造を採用可能である。 In this embodiment, since the U-shaped bracket 41 inserted into the long hole 34 of the wedge member 3 is fixed to the fixture main body 1, the wedge member 3 retreats carelessly from the driving opening 19. Even if this happens, the wedge member 3 is locked by the U-shaped fitting 41 as shown by the chain line in FIG. 8, so that the wedge member 3 is prevented from falling off the fixture body 1. Needless to say, the wedge member 3 drop-off preventing means 4 is not limited to the one using the U-shaped metal fitting 41, and various locking structures can be employed.

ところで、前記実施形態は、前記取付け具１０を使用して火打ち部材本体１００を介して水平材２００に取り付ける例で説明したものであるが、取付け具１０は、水平材２００を対象にしたものに使用が限定されるものではなく、垂直姿勢の棒材、例えば図１の支柱３００に被取付け物体を取り付けるような場合でも、使用できるものである。 By the way, although the said embodiment was demonstrated in the example attached to the horizontal material 200 via the burning member main body 100 using the said mounting tool 10, the mounting tool 10 is what used the horizontal material 200 as object. The use is not limited, and it can be used even when an object to be attached is attached to a bar in a vertical posture, for example, a support 300 in FIG.

さらに言うまでもなく、本発明の火打ち部材は、高さの異なる２つの水平材同士を連結する場合にも使用することが可能である。 Furthermore, it goes without saying that the firing member of the present invention can also be used when two horizontal members having different heights are connected.

また、前記実施形態では、外嵌孔部１４，１５を有する前後一対の二股片部片部１１，１２を備えた取付け具本体１を採用した例で説明したが、このような取付け具本体１に限られるものではなく、例えば、図９に示すように、金属板等の板材をＵ字形に折曲し、折り曲げられた一対の対向片部１１０，１２０間の空間を前記水平材２００に対する嵌合孔部として構成し、さらに、これら両対向片部１１０，１２０にそれぞれ形成された角孔１１０ａ，１２０ａにより、楔部材打ち込み用開通部１９を構成したものであってもよい。 Moreover, although the said embodiment demonstrated the example which employ | adopted the fixture main body 1 provided with the front-and-rear pair of forked piece part parts 11 and 12 which have the external fitting hole parts 14 and 15, such a fixture main body 1 was demonstrated. For example, as shown in FIG. 9, a plate material such as a metal plate is bent in a U shape, and a space between the pair of bent opposing pieces 110 and 120 is fitted to the horizontal material 200. Further, the wedge member driving opening portion 19 may be configured by a square hole 110a, 120a formed as a joint hole portion and formed in the opposing piece portions 110, 120, respectively.

なお、前記実施形態では、取付け具１０の被取付け物体用連結部２に、被取付け物体として火打ち部材本体１００のような棒材を取付けた例で説明したが、被取付け物体用連結部２として、棒材以外の各種被取付け物体に合わせた連結構造を採用可能である。 In addition, although the said embodiment demonstrated in the example which attached the bar material like the fire-ignition member main body 100 as a to-be-attached object to the to-be-attached object connection part 2 of the fixture 10, as the to-be-attached object connection part 2, Further, it is possible to adopt a connection structure that matches various mounted objects other than the bar.

また上記実施形態では、楔部材３における一対の対向壁部３２，３３の各先端面３２ａ，３３ａを、圧接用斜面として構成し、その圧接用斜面を複数の段階に分けてるようにしているが、それだけに限られず、本発明においては、楔部材における一対の対向壁部の各基端面（連結壁部２１の外面）側を圧接用斜面に形成してその圧接用斜面を複数の段階に分けるようにしても良い。もっとも本発明においては、上記実施形態のように、楔部材における一対の対向壁部の各先端面、つまり棒材の外周面に接触する側の面を、圧接用斜面として、その圧接用斜面を複数の段階に分けることにより、楔部材の長さを、より短く形成することが可能となる。 Moreover, in the said embodiment, although each front end surface 32a and 33a of a pair of opposing wall part 32 and 33 in the wedge member 3 is comprised as a press-contact slope, it is made to divide the press-contact slope into several steps. However, the present invention is not limited thereto, and in the present invention, the respective base end surfaces (outer surfaces of the connecting wall portion 21) of the pair of opposing wall portions of the wedge member are formed on the pressure contact slope, and the pressure contact slope is divided into a plurality of stages. Anyway. However, in the present invention, as in the above embodiment, each tip surface of the pair of opposing wall portions of the wedge member, i.e., the surface in contact with the outer peripheral surface of the bar is defined as the pressure contact slope, and the pressure contact slope is defined as the pressure contact slope. By dividing into a plurality of stages, the length of the wedge member can be made shorter.

また上記実施形態においては、取付け具１０を、棒材（水平材）に対し水平方向から嵌合する場合を例に挙げて説明したが、それだけに限られず、本発明においては、取付け具を棒材に対し、水平方向以外の方向例えば、上方等の垂直方向から嵌合するようにしても良い。 Moreover, in the said embodiment, although demonstrated taking the case where the fixture 10 was fitted from the horizontal direction with respect to a bar (horizontal material), it is not restricted only to it, In this invention, a fixture is a bar. On the other hand, you may make it fit from directions other than a horizontal direction, for example, vertical directions, such as an upper direction.
