Description

本発明はＰＣ部材用吊り治具およびＰＣ部材の引き寄せ工法に関するものである。   The present invention relates to a PC member suspension jig and a PC member drawing method.

従来のＰＣ部材用吊り治具およびＰＣ部材の引き寄せ工法としては、例えば特開平５−３４６０６４号の発明が知られている。これは、下方に引込みワイヤーと牽引きワイヤーとを設けたＰＣ部材をクレーンで吊り上げた後、この引込みワイヤーと牽引きワイヤーとを利用してＰＣ部材を躯体側に引き寄せるものである。
特開平５−３４６０６４号公報 As a conventional PC member suspending jig and a PC member pulling method, for example, the invention of Japanese Patent Laid-Open No. 5-346064 is known. In this method, a PC member provided with a pull-in wire and a pulling wire is lifted by a crane, and then the PC member is drawn toward the housing using the pull-in wire and the pulling wire.
JP-A-5-346064

しかし、上記のＰＣ部材の引き寄せ工法は、作業者が躯体から身を乗り出してＰＣ部材の引き寄せを行うため、危険な作業になっていた。   However, the above-described PC member pulling method has been a dangerous work because the operator gets out of the housing and pulls the PC member.

本発明は、上記のような問題に鑑みてなされたものであり、その目的は、ＰＣ部材を安全かつ確実に躯体側に引き寄せることができるＰＣ部材用吊り治具およびＰＣ部材の引き寄せ工法を提供することである。   The present invention has been made in view of the above problems, and an object of the present invention is to provide a PC member suspension jig and a PC member drawing method that can draw the PC member to the housing side safely and reliably. It is to be.

以上の課題を解決するためのＰＣ部材用吊り治具は、連結材で平行に接合された湾曲状の吊りレールには、ローラーで移動するスライド部材がスライド自在に取り付けられ、該スライド部材にはワイヤーを引っ掛ける掛止片が設けられたことを特徴とする。また吊りレールには、スライド部材のスライドを緩衝する緩衝器と、スライド部材のスライドを停止させるストッパとが設置されたことを含む。また吊りレールの先端部には、躯体に接合する接合板が設けられたことを含むものである。   In the suspension jig for PC members for solving the above problems, a slide member that is moved by a roller is slidably attached to a curved suspension rail joined in parallel by a connecting member. It is characterized in that a hooking piece for hooking the wire is provided. The suspension rail includes a shock absorber for buffering the slide of the slide member and a stopper for stopping the slide of the slide member. In addition, the tip of the suspension rail includes that a joining plate for joining to the housing is provided.

またＰＣ部材の引き寄せ工法は、請求項１〜請求項３のいずれかのＰＣ部材用吊り治具を使用するものであり、ＰＣ部材をワイヤーでスライド部材に引っ掛けてクレーンで吊り上げるとともに、吊りレールの先端部を接合板で所定階の床板に回転自在に接合した後、吊りレールの後方側を上側に引き上げてスライド部材をライドさせてＰＣ部材を躯体側に引き寄せることを特徴とする。   The PC member pulling method uses the PC member suspension jig according to any one of claims 1 to 3, and the PC member is hooked on a slide member by a wire and lifted by a crane. After the front end portion is rotatably joined to a floor plate of a predetermined floor with a joining plate, the rear side of the suspension rail is pulled upward to ride the slide member, and the PC member is drawn to the housing side.

ＰＣ部材用吊り治具が湾曲状の吊りレールで形成されているため、カウンターウエイトなどを必要とせず、軽量で揚重効率の向上を図ることができる。ＰＣ部材の移動に機械的な手段を必要としないため、ＰＣ部材用吊り治具が簡単な構成になる。スライドレールが湾曲しているため、ＰＣ部材を躯体側に安全でかつ円滑に引き寄せすることができる。   Since the PC member suspension jig is formed of a curved suspension rail, a counterweight or the like is not required, and the weight and weight can be improved. Since no mechanical means is required to move the PC member, the PC member suspension jig has a simple configuration. Since the slide rail is curved, the PC member can be safely and smoothly pulled toward the housing side.

以下、本発明のＰＣ部材用吊り治具（以下吊り治具という）およびＰＣ部材の引き寄せ工法の実施の形態を図面に基づいて説明する。はじめに、吊り治具について説明し、その後、この吊り治具を使用した引き寄せ工法について説明するが、各実施の形態において同じ構成は同じ符号を付して説明し、異なった構成にのみ異なった符号を付して説明する。   Embodiments of a PC member suspension jig (hereinafter referred to as a suspension jig) and a PC member drawing method according to the present invention will be described below with reference to the drawings. First, a suspension jig will be described, and then a drawing method using this suspension jig will be described. In each embodiment, the same components are described with the same reference numerals, and only different configurations are denoted by different reference numerals. Will be described.

図１は、本発明の吊り治具１を示したものであり、連結材２で平行に接続された吊りレール３と、この吊りレール３にスライド自在に取り付けられたスライド部材４とから構成されている。この吊りレール３は断面Ｈ形であり、弓状に湾曲され、連結材２に取り付けられた吊りワイヤー５でクレーンのフック６に引っ掛けられるようになっている。   FIG. 1 shows a suspension jig 1 of the present invention, which is composed of a suspension rail 3 connected in parallel by a connecting member 2 and a slide member 4 slidably attached to the suspension rail 3. ing. The suspension rail 3 has an H-shaped section, is curved in an arc shape, and is hooked on a crane hook 6 by a suspension wire 5 attached to the connecting member 2.

図２に示すように、スライド部材４の枠体７の両側壁８には、二つのローラー９が取り付けられ、該ローラー９が吊りレール３の下側のフランジ１０に設置されて、吊りレール３が移動できるようになっている。また枠体７の下面には、ＰＣ部材１１のワイヤー１２を引っ掛ける掛止片１３が設けられている。また吊りレール３の先端のウエブ１４両面には、スライド部材４の移動を緩衝する緩衝器１５が設置され、この緩衝器１５の緩衝板１６が枠体７に当接する位置に設けられている。また緩衝器１５前方のフランジ１０の下面には、スライド部材４を停止させるストッパ１７が設けられている。したがって、吊りレール３は、緩衝器１５で緩衝されつつ、ゆっくりと移動して、ストッパ１７で停止される。   As shown in FIG. 2, two rollers 9 are attached to both side walls 8 of the frame 7 of the slide member 4, and the rollers 9 are installed on the lower flange 10 of the suspension rail 3. Can be moved. Further, a hooking piece 13 for hooking the wire 12 of the PC member 11 is provided on the lower surface of the frame body 7. Further, shock absorbers 15 for buffering the movement of the slide member 4 are installed on both surfaces of the web 14 at the tip of the suspension rail 3, and the buffer plates 16 of the shock absorbers 15 are provided at positions where they contact the frame body 7. A stopper 17 for stopping the slide member 4 is provided on the lower surface of the flange 10 in front of the shock absorber 15. Therefore, the suspension rail 3 moves slowly while being buffered by the shock absorber 15 and is stopped by the stopper 17.

また、吊りレール３の先端のウエブ１４には、床板１８のファスナー１９に接合するための接合板２０が設けられ、図２に示すように、この接合板２０がピン２１でファスナー１９に回転自在に接合されている。したがって、この接合板２０を中心に吊り治具１の後側を上げ下げすると、スライド部材４が吊りレール３を移動して、その移動が緩衝器１５で緩衝されるとともに、スットパ１７で停止される。   Further, the web 14 at the end of the suspension rail 3 is provided with a joining plate 20 for joining to the fastener 19 of the floor board 18, and as shown in FIG. It is joined to. Therefore, when the rear side of the suspension jig 1 is raised and lowered around the joining plate 20, the slide member 4 moves on the suspension rail 3, and the movement is buffered by the shock absorber 15 and stopped by the stopper 17. .

次に、この吊り治具１を使用したＰＣ部材の引き寄せ工法（以下引き寄せ工法という）の実施の形態について説明する。この実施の形態においてＰＣ部材１１は外壁パネル２２であるが、これに限定されるものではなく、その他のＰＣ部材であっても良い。   Next, an embodiment of a PC member drawing method using the hanging jig 1 (hereinafter referred to as a drawing method) will be described. In this embodiment, the PC member 11 is the outer wall panel 22, but is not limited to this and may be another PC member.

はじめに、外壁パネル２２をワイヤー１２でスライド部材４の掛止片１３に引っ掛ける。次に、この外壁パネル２２を引っ掛けた吊り治具１を、図３に示すように、吊りワイヤー５でクレーンのフック６に引っ掛けて吊り上げる。このときスライド部材４は吊りレール３の一番下側の中心部に位置するため、外壁パネル２２はバランスが取れた状態で吊り上げられて、躯体２３の外壁取り付け箇所に位置するようになる。そして、吊りレール３の先端の接合板２０を所定階の床板１８のファスナー１９に接合し、これを中心に回転できるようにする。   First, the outer wall panel 22 is hooked on the retaining piece 13 of the slide member 4 with the wire 12. Next, as shown in FIG. 3, the hanging jig 1 on which the outer wall panel 22 is hooked is hooked on the crane hook 6 with the hanging wire 5 and lifted. At this time, since the slide member 4 is located at the center of the lowermost side of the suspension rail 3, the outer wall panel 22 is lifted in a balanced state and is located at the outer wall attachment location of the housing 23. Then, the joining plate 20 at the tip of the suspension rail 3 is joined to the fastener 19 of the floor plate 18 on the predetermined floor so that it can be rotated around this.

次に、図４に示すように、クレーンで吊り治具１の後側を持ち上げて回転させると、スライド部材４が吊りレール３を移動して、外壁パネル２２が躯体２３側に引き寄せられる。そして、このスライド部材４の移動が緩衝器１５で緩衝されつつ、ストッパ１７で停止されるので、外壁パネル２２が躯体２３の外壁取り付け箇所に位置して、取り付け可能になる（図２参照）。このように吊り治具１の後側を持ち上げるだけで、外壁パネル２２を躯体２３側に簡単に引き寄せることができる。   Next, as shown in FIG. 4, when the rear side of the suspension jig 1 is lifted and rotated by a crane, the slide member 4 moves the suspension rail 3 and the outer wall panel 22 is drawn toward the housing 23 side. Since the movement of the slide member 4 is buffered by the shock absorber 15 and stopped by the stopper 17, the outer wall panel 22 is positioned at the outer wall attachment position of the housing 23 and can be attached (see FIG. 2). Thus, the outer wall panel 22 can be easily pulled toward the housing 23 by simply lifting the rear side of the hanging jig 1.

外壁パネルを吊り下げた吊り治具の斜視図である。It is a perspective view of the hanging jig which suspended the outer wall panel. （１）は吊りレールの先端部を床板のファスナーに接合した断面図、（２）は（１）のＡ−Ａ線断面図である。(1) is sectional drawing which joined the front-end | tip part of the suspension rail to the fastener of the floor board, (2) is AA sectional view taken on the line of (1). 吊り治具の先端部を床板に接合した図である。It is the figure which joined the front-end | tip part of the hanging jig to the floor board. 吊り治具の後側を持ち上げた図である。It is the figure which lifted the rear side of the hanging jig.
