本考案は、柱鉄筋等に親綱、親綱フック、安全帯フックを容易且つ迅速に安定した状態で取付けられるようにした柱鉄筋への親綱取付用具に関するものである。   The present invention relates to a tool for attaching a master rope to a column reinforcing bar, which allows a master rope, a master rope hook, and a safety belt hook to be easily and quickly attached in a stable state.

鉄筋コンクリートの建築物等を施工するにおいては、足場を構築しないで作業を行なうことが多く、その際柱鉄筋に親綱を取付けて張設したり、安全帯フックを取付けたりして作業者の安全対策を講じているが、柱鉄筋に親綱を取付けたり、安全帯フックを取付けたりするのが容易且つ迅速に行なえないことや、安定した取付けが行えないことによる安全上の問題がある。   When constructing a reinforced concrete building, etc., it is often done without constructing a scaffold. At that time, a master rope is attached to the column reinforcing bar, or a safety belt hook is attached to secure the worker's safety. Although measures are taken, there are safety problems due to the fact that it is not possible to easily and quickly attach the master rope to the column rebar or attach the safety belt hook, and the stable attachment cannot be performed.

又、柱鉄筋に親綱や安全帯フックを取付けられるようにしたものとして、略U字形を成し、彎曲している基部を有する枠体に柱鉄筋を貫通させるための貫通路を形成して成る金具本体に固定用ねじを螺着し、貫通路内に挿通された柱鉄筋を固定用ねじの先端部で押して枠体の上端面と下端面に付着した平板部材に押し当てることにより柱鉄筋に固定し、略U字形の先端部に親綱を緊結するための取付孔を設けた柱鉄筋用親綱金物(特許文献1参照)が開示され、公知となっている。   In addition, it is possible to attach a master rope or safety belt hook to the column reinforcement, and it has a substantially U shape, and forms a through passage for allowing the column reinforcement to pass through a frame having a bent base. A fixing screw is screwed onto the metal fitting body, and the column reinforcing bar inserted into the through passage is pushed by the tip of the fixing screw and pressed against the flat plate members attached to the upper end surface and the lower end surface of the frame body. And a steel bar for steel bar reinforcement (see Patent Document 1), which is provided with a mounting hole for fastening the master rope to a substantially U-shaped tip.

特開平11−303412号公報Japanese Patent Laid-Open No. 11-303212

しかしながら、上記特許文献1に記載される技術によれば、略U字形の枠体の上端と下端とに平板部材が固着されて、該平板部材と枠体のU字溝部の間に柱鉄筋が挿通される貫通路が形成され、該貫通路に柱鉄筋を挿通して固定用ねじで締め付けることにより柱鉄筋に固定するようになっており、簡単且つ確実に取付けはできるが、柱鉄筋の端部から前記貫通路に挿通しなければならず、立設された柱鉄筋のどの高さ位置でも容易且つ迅速に着脱できなく、作業性の向上が図られない問題点を有する。
従って、本考案は、立設された柱鉄筋のどの高さ位置でも容易且つ迅速に着脱でき、安定した取付けのできる柱鉄筋への親綱取付用具を提供することを目的とし、該目的を達成することを課題とするものである。
However, according to the technique described in Patent Document 1, the flat plate member is fixed to the upper end and the lower end of the substantially U-shaped frame, and the column reinforcing bar is formed between the flat plate member and the U-shaped groove portion of the frame. A penetrating passage is formed, and it is fixed to the column reinforcing bar by inserting the column reinforcing bar into the through path and tightening it with a fixing screw. There is a problem that it is necessary to pass through the through-hole from the section, and it cannot be easily and quickly attached and detached at any height position of the erected column reinforcing bar, and workability cannot be improved.
Accordingly, the present invention aims to provide a main rope attaching tool to a column reinforcing bar which can be easily and quickly attached and detached at any height position of the standing column reinforcing bar and can be stably attached. It is an object to do.

上記目的を達成するために、本考案は以下に記載するような手段を講じてなる柱鉄筋への親綱取付用具とした。
(1)略V字状に成形された枠体の背部に、親綱取付用の長円孔を穿設したプレートを突出させて設けると共に、枠体の左右両開先部に挿通孔を穿設して、該挿通孔に、締付ボルトを螺子着したプレートが、片端部を着脱可能にして左右に移動自在に挿通されてなることを特徴とする柱鉄筋への親綱取付用具である。締付ボルトを螺子着したプレートの片端部を枠体の開先部の挿通孔より離脱させることにより、プレートは開閉自在となり、立設された柱鉄筋の横からの着脱ができて、どの高さ位置でも取付が容易且つ迅速に行なえる。
(2)締付ボルトを螺子着したプレートの別端部が、くの字状に成形され、該成形された端部にストッパーを設けてなることを特徴とする前項(1)記載の柱鉄筋への親綱取付用具である。締付ボルトを螺子着したプレートの別端部がくの字状に成形されることにより、前記プレートが開閉しやすく、くの字状に曲げた端部にストッパーを設けることにより挿通穴よりプレートが離脱しない。
(3)締付ボルトが、プレートの面にナットを付着させて複数螺子着してなることを特徴とする前項(1)又は(2)記載の柱鉄筋への親綱取付用具である。
プレート面にナットを付着させて締付ボルトを螺子着することにより、プレートに螺子加工できないような薄いプレートでも締付ボルトによる締め付けに有効な螺子部が得られる。
In order to achieve the above object, the present invention provides a main rope attaching tool to a column reinforcing bar which has the following measures.
(1) A plate having an oval hole for attaching a master rope is provided at the back of a frame body formed in a substantially V-shape, and insertion holes are formed in both left and right groove portions of the frame body. A tool for attaching a main rope to a column reinforcing bar, wherein a plate having a fastening bolt screwed into the insertion hole is inserted into the insertion hole so that one end of the plate is detachable. . The plate can be opened and closed by removing one end of the plate screwed with the tightening bolt from the insertion hole in the groove portion of the frame, and the height of the standing column rebar can be removed from the side. It can be installed easily and quickly even in this position.
(2) The column reinforcing bar according to (1) above, wherein the other end of the plate to which the tightening bolt is screwed is formed in a U-shape, and a stopper is provided on the formed end. It is a tool for attaching the master rope. The other end of the plate screwed with the tightening bolt is formed in a U shape, so that the plate can be easily opened and closed, and a stopper is provided at the end bent in the U shape so that the plate can be inserted from the insertion hole. Do not leave.
(3) The master rope attaching tool to the column reinforcing bar according to (1) or (2) above, wherein the tightening bolt is formed by attaching a plurality of screws by attaching nuts to the surface of the plate.
By attaching the nut to the plate surface and screwing the tightening bolt, a screw portion effective for tightening with the tightening bolt can be obtained even for a thin plate that cannot be screwed into the plate.

上記手段に記載する如く、略V字状に成形された枠体の背部に、親綱取付用の長円孔を穿設したプレートを突出させて設けると共に、枠体の左右両開先部に挿通孔を穿設して、該挿通孔に、締付ボルトを螺子着したプレートの片端部を着脱可能にして左右に移動自在に挿通されてなるから、締付ボルトを螺子着したプレートの片端部を挿通孔より離脱させることにより、プレートが開閉自在となり、立設された柱鉄筋の横から着脱ができて、どの高さ位置でも取付けが容易且つ迅速に行え、作業性の向上が図られる。   As described in the above means, a plate having an oval hole for attaching the master rope is provided on the back of the frame body formed in a substantially V shape, and is provided at both left and right groove portions of the frame body. An insertion hole is formed, and one end of a plate screwed with a tightening bolt is detachably inserted into the insertion hole so that the plate can be moved left and right. By detaching the part from the insertion hole, the plate can be opened and closed, and can be attached / detached from the side of the erected column reinforcement, and can be easily and quickly installed at any height position, thereby improving workability. .

締付ボルトの締付けが、略V字状に成形した枠体の開先側部に作用しないから、枠体の開先部が開くおそれがなく、しっかりとクランプされた状態が保たれ、安全性の向上も図られる。   Since the tightening of the tightening bolt does not act on the groove side portion of the frame body formed in a substantially V-shape, there is no possibility that the groove portion of the frame body will open, and the clamped state will be maintained and safety will be maintained. Is also improved.

締付ボルトを螺子着したプレートは、移動・開閉は自在であるが、枠体から脱落することはなく、プレートの開閉、ボルトの締付けが容易且つ迅速に行える。   The plate on which the tightening bolt is screwed can be moved and opened / closed freely, but does not fall off from the frame, and the plate can be easily opened and closed and the bolt can be fastened.

構造は、極めてシンプルなものであり、安価に製作できる。   The structure is extremely simple and can be manufactured at low cost.

本考案を実施するための最良の形態を、以下に記載する実施例にて図面を参照して詳細に説明する。   The best mode for carrying out the present invention will be described in detail in the following embodiments with reference to the drawings.

図1は、本考案の実施例を示す斜視図である。図示するように、本考案は、略V字状に形成された枠体1の背部に、親綱取付用の長円孔2a,2aを穿設したプレート2,2を突出させて設けると共に、枠体1の左右両開先部には挿通孔1a,1a,・・・を穿設して、該挿通孔に、締付ボルト3,3を螺子着したプレート4,4が、片端部4a,4aを着脱できるようにして左右に移動自在に挿通されている。   FIG. 1 is a perspective view showing an embodiment of the present invention. As shown in the figure, the present invention is provided with a plate 2, 2 provided with oval holes 2 a, 2 a for attaching a master rope, protruding from the back of a frame 1 formed in a substantially V shape, Plates 4 and 4 in which insertion holes 1a, 1a,... Are formed in the left and right groove portions of the frame 1 and fastening bolts 3 and 3 are screwed into the insertion holes are provided at one end 4a. , 4a is detachably inserted so as to be detachable.

前記枠体1、プレート2,2、プレート4,4は、厚さがおおむね3〜4mm程度の圧延鋼板が使用され、枠体1の背部へのプレート2,2は溶接による接合としているが、これに限定されるものではない。枠体1とプレート2,2を鋳物やアルミダイカスト等により一体に成形しても良い。   The frame 1, plates 2, 2, and plates 4, 4 are made of a rolled steel plate having a thickness of about 3-4 mm, and the plates 2, 2 to the back of the frame 1 are joined by welding, It is not limited to this. The frame 1 and the plates 2 and 2 may be integrally formed by casting or aluminum die casting.

又、前記プレート4,4の別端部4b,4bは、くの字状に成形されており、くの字状に成形された端部にはストッパー5,5が設けてあり、挿通孔1a,1a,・・・に挿通させたプレート4,4のプレート面の略中央部には、ナット3a,3aを付着させて締付ボルト3,3が螺子着されている。プレート面にナット3a,3aを付着させて締付ボルト3,3を螺子着するのは、プレート4,4の板厚が、螺子締めするのに有効な螺子部が形成されない場合で、充分な厚さがある場合は、ナット3a,3aを付着させる必要はない。   Further, the other end portions 4b and 4b of the plates 4 and 4 are formed in a U shape, and stoppers 5 and 5 are provided on the end portions formed in a U shape, and the insertion hole 1a. , 1a,..., 1a,... Are fastened with nuts 3a and 3a to the center portions of the plate surfaces of the plates 4 and 4 that are inserted through the plates 4 and 4. The nuts 3a and 3a are attached to the plate surface and the tightening bolts 3 and 3 are screwed together when the plate thickness of the plates 4 and 4 does not form a screw portion effective for screwing. When there is a thickness, it is not necessary to attach the nuts 3a and 3a.

なお、前記プレート2、プレート4は、それぞれ2枚にての実施例であるが、使用状況に応じて図2に示すようにそれぞれ1枚にしても良く、親綱取付用の長円孔2aは放射状や縦方向にしても良い。締付ボルト3は、柱鉄筋へ安定して取付け固定するには複数にするのが好ましい。親綱等の先端部に取付けられたフック等を迅速に引掛けて取付けるには図示するような長円孔2aとするのが好ましい。   In addition, although the said plate 2 and the plate 4 are the examples each with two sheets, according to a use condition, as shown in FIG. 2, you may make each one and the oval hole 2a for parent rope attachment May be radial or longitudinal. It is preferable to use a plurality of tightening bolts 3 in order to stably attach and fix the bolts to the column reinforcement. In order to quickly hook and attach a hook or the like attached to the tip of a master rope or the like, an oval hole 2a as shown is preferable.

図3は、締付ボルト3を締め付けて柱鉄筋6に取付け固定した状態の図1の平面視断面図である。締付ボルト3をナット3aにより螺子着したプレート4は、枠体1の左右両開先部に穿設された挿通孔1a,1aに挿通された状態で締付ボルト3の先端と、略V字状に成形された枠体1の溝部1bとで、立設された柱鉄筋6の側面が押し付けられていて、略V字状に成形された枠体1の開先が開くようなことはなくしっかりと固定され、締付ボルト3を緩めると上下移動は自由となる。   FIG. 3 is a plan view cross-sectional view of FIG. 1 in a state in which the fastening bolt 3 is fastened and fixed to the column rebar 6. The plate 4 on which the tightening bolt 3 is screwed with the nut 3a is inserted into the insertion holes 1a and 1a formed in the left and right groove portions of the frame body 1 and the end of the tightening bolt 3 is substantially V. The groove 1b of the frame body 1 formed into a letter-shape is pressed against the side surface of the standing column reinforcing bar 6, and the groove of the frame body 1 shaped into a substantially V-shape is opened. If the fastening bolt 3 is loosened, the vertical movement is free.

図4は、締付ボルト3を螺子着したプレート4を開いた状態を示す図1の平面視断面図である。図3の状態で締付ボルト3を緩め、プレート4を右へ移動させてプレート4の片端部4aを枠体1の挿通孔1aより離脱させ、別端部4bのくの字状に成形された部分が別方の挿通孔1aに位置する所で開くと、図4に示すような状態となり、この状態で立設された柱鉄筋6の横からの出入ができる。   4 is a plan view cross-sectional view of FIG. 1 showing a state in which the plate 4 to which the tightening bolt 3 is screwed is opened. In the state of FIG. 3, the fastening bolt 3 is loosened, the plate 4 is moved to the right to disengage one end 4 a of the plate 4 from the insertion hole 1 a of the frame body 1, and the other end 4 b is formed into a dogleg shape. When the part is opened at a position located in the other insertion hole 1a, the state as shown in FIG. 4 is obtained, and the column reinforcing bars 6 erected in this state can be taken in and out from the side.

前記プレート4は、片端部4aが挿通孔1aより離脱しても、別端部に設けられたストッパー5と、螺子着された締付ボルト3やプレート面に付着されたナット3aに当って別方の挿通孔1aより離脱することはない。プレート4の片端部4aと別端部4bが挿通孔1a,1aより離脱すると落下し、それを拾い上げて挿通孔1a,1aに挿通して取付けるのも甚だ面倒である。   Even if the one end 4a is detached from the insertion hole 1a, the plate 4 is separated from the stopper 5 provided at the other end and the tightening bolt 3 screwed or the nut 3a attached to the plate surface. It does not detach from the insertion hole 1a. When one end 4a and the other end 4b of the plate 4 are separated from the insertion holes 1a and 1a, the plate 4 falls, and it is very troublesome to pick it up and insert it into the insertion holes 1a and 1a.

なお、前記プレート4の別端部に設けたストッパー5は、プレート片を溶接等で付着させているが、図5に示すようにピンを螺子立てしたストッパー5Aにしても良い。そうすれば、ストッパー5Aを緩めて取り外すことによりプレート4の別端部は、枠体1の別の挿通孔1aより容易に取り外すことができ、プレート4のオーバーホール等に有用となる。   The stopper 5 provided at the other end of the plate 4 has a plate piece attached by welding or the like, but may be a stopper 5A in which a pin is screwed as shown in FIG. Then, by loosening and removing the stopper 5 </ b> A, the other end portion of the plate 4 can be easily removed from the other insertion hole 1 a of the frame body 1, which is useful for overhauling the plate 4.

図6は、以上のようにしてなる本考案を、立設された柱鉄筋に取付け固定して親綱を張設した使用例を示す斜視図である。
略V字状に成形された枠体1の溝部1bと、プレート4,・・・に螺子着された締付ボルト3,・・・の先端で、立設された柱鉄筋6の側部が押し付けられて固定されており、親綱7,7は先端部に接続されたフック8,8を、プレート2,2の長円孔2a,2aに引掛けることにより取付けられ、張設されている。
FIG. 6 is a perspective view showing an example of use in which the present invention constructed as described above is attached and fixed to a standing column reinforcing bar and a master rope is stretched.
The side part of the column reinforcing bar 6 erected at the tip of the groove part 1b of the frame body 1 formed in a substantially V shape and the fastening bolts 3 screwed to the plates 4,. The master rope 7, 7 is attached and stretched by hooking hooks 8, 8 connected to the tip end thereof into the oblong holes 2a, 2a of the plates 2, 2. .

なお、親綱7,7は、プレート2,2の長円孔2a,2aに直接結び付けて張設しても良く、又プレート2,2に穿設された長円孔2a,2aには親綱のみならず、直接人体を保持する安全帯フック等を引掛けて使用しても良い。   The master ropes 7 and 7 may be directly connected to the oblong holes 2a and 2a of the plates 2 and 2 and stretched, and the oblong holes 2a and 2a drilled in the plates 2 and 2 are parent.
