(57) [Summary] [Objective] The PC member manufacturing process is simplified compared to the conventional method of embedding the hook by a hanging jig that is easily removable and can be used repeatedly. [Structure] A steel pipe having a shackle mounting hole 2 is used as a steel pipe 1.
After welding the steel pipe 1 onto the protruding screw rebar 4 of the PC member, the nut 3 is tightened to attach the steel pipe 1 to the screw rebar 4.
Description
【０００１】[0001]
本考案は、突出したねじ鉄筋を有するプレキャストコンクリート（以下ＰＣと 略す）部材を吊るための治具に関するものである。 The present invention relates to a jig for suspending a precast concrete (hereinafter abbreviated as PC) member having a protruding screw reinforcing bar.
【０００２】[0002]
ＰＣ部材を吊るには、製造時にＰＣ部材の頂部に予めフックを埋めこんでプレ キャストしておき、このフックにワイヤーをかけて、クレーンで吊るのが通常で ある。 In order to suspend the PC member, it is usual to bury a hook on the top of the PC member in advance at the time of manufacturing and precast it, and then wire the hook and hang it with a crane.
【０００３】 しかし、前記部材を横置状態で製造する場合には、頂部となる面に型枠がある ので、フックを埋込むために、それに相当するように型枠を加工することが必要 となり、ＰＣ部材製造工程が複雑になる。However, when the above-mentioned member is manufactured in a horizontal position, since the formwork is on the top surface, it is necessary to process the formwork correspondingly to embed the hook. , The PC member manufacturing process becomes complicated.
【０００４】[0004]
本考案は、かかるフック埋込みの手間を要することなく、簡便にＰＣ部材を吊 るための吊治具を提供することにある。 An object of the present invention is to provide a hanging jig for easily hanging a PC member without the trouble of embedding the hook.
【０００５】[0005]
本考案は鉄筋が頂部より突出しているＰＣ部材の突出した鉄筋を利用した吊治 具であり、この鉄筋として、ネジ鉄筋を利用し、このネジ鉄筋に、鉄筋径より内 径がやや大きく、その長さが鉄筋の突出長より短かい鋼管をかぶせ、ついでナッ トをはめて締め、鋼管をネジ鉄筋に取付けるものである。 The present invention is a suspension jig that uses a projecting rebar of a PC member in which the rebar projects from the top. As the rebar, a screw rebar is used, and the screw rebar has an inner diameter slightly larger than the rebar diameter. A steel pipe whose length is shorter than the protruding length of the rebar is covered, and then a nut is attached and tightened to attach the steel pipe to the screw rebar.
【０００６】 そして、この鋼管には予め、シャックルを取付けるための孔を有する鋼板を溶 接しておく。Then, a steel plate having a hole for attaching a shackle is welded to this steel pipe in advance.
【０００７】 この固定のためのナットは予め鋼管の端部に溶接し一体化しておいてもよい。The nut for this fixing may be welded to and integrated with the end of the steel pipe in advance.
【０００８】 本考案の対象となるＰＣ部材は主として柱状物であるがこれに限られることは ない。The PC member that is the subject of the present invention is mainly a columnar member, but the present invention is not limited to this.
【０００９】 この柱状物としては角柱、円柱、中空柱何れでもよい。ＰＣ部材の突出する鉄 筋は全てをネジ鉄筋であってもよいが、本吊治具を装着しない鉄筋はネジ鉄筋で ある必要はない。The pillar may be a prism, a cylinder, or a hollow pillar. All the reinforcing bars protruding from the PC member may be screw reinforcing bars, but the reinforcing bars to which the main suspension jig is not attached need not be screw reinforcing bars.
【００１０】 通常本吊治具は吊り上げ時の力のバランスを取り鉄筋の曲りや損傷を防ぐため 、対角の二個のネジ鉄筋に装着される。Usually, the main suspension jig is attached to two diagonal screw rebars in order to balance the force at the time of lifting and prevent bending and damage of the rebar.
【００１１】 また、２本のワイヤーで吊り上げる場合、その２本のワイヤーが傾斜するとき には、その水平分力により、ネジ鉄筋に曲げ応力が生ずるが、この応力が大きく ならないためにワイヤー取付位置は鉄筋のコンクリート定着側に近いことが好ま しい。鋼管の長さは、余りに短いと本吊治具の着脱のためのナットの移動量が大 きくなり、時間を要することとなるので突出したネジ鉄筋より若干短かい程度と し、着脱時間を短かくすることが好ましい。In addition, when the two wires are lifted, when the two wires are tilted, the horizontal component force causes bending stress in the screw rebar, but this stress does not increase, so the wire mounting position Is preferably close to the concrete anchoring side of the rebar. If the length of the steel pipe is too short, the amount of movement of the nut for attaching / detaching the main suspension jig will be large, and it will take time. It is preferable to do so.
【００１２】[0012]
実施例について図面を参照して説明する。 図１は四角柱のＰＣ部材を吊り上げた状態を示すもので、四隅に配置された主 筋の中の二本に本吊治具を装着し、ワイヤー６を、シャックル取付孔２を経由し て取付けている。 Examples will be described with reference to the drawings. Fig. 1 shows a state in which the PC member of a square pole is lifted up. The main suspension jigs are attached to two of the main bars arranged at the four corners, and the wire 6 is passed through the shackle mounting hole 2. It is installed.
【００１３】[0013]
本吊治具は単純な構造で製作が容易であり、また繰返し使用できるのでコスト 低下につながる。現場での着脱も極めて容易である。 This suspension jig has a simple structure, is easy to manufacture, and can be used repeatedly, resulting in cost reduction. It is extremely easy to put on and take off on the spot.
