【産業上の利用分野】この発明は、鉄筋コンクリート構
造物におけるネジ鉄筋の定着に用いる定着金物に関する
ものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing hardware used for fixing a threaded reinforcing bar in a reinforced concrete structure.
【０００２】[0002]

る。2. Description of the Related Art Conventionally, as a fixing hardware for this type of screw reinforcing bar, as shown in FIG.
And two nuts 21 for holding and fixing the nut. Or, as shown in FIG. 9, a special fixing nut 22, for example,
What consists of a filling type screw fixing hardware etc. is generally known.
【０００３】そして、この定着金物は、はり主筋の柱と
梁の接合部での定着や、主筋における付着耐力の増加を
期待する部分の定着等に用いるものである。[0003] The fixing hardware is used for fixing at a joint between a column and a beam of a main beam of a beam, and fixing a portion of the main bar where an increase in adhesion strength is expected.

両ナットまたは定着ナットを回転させながら長手方向へ
移動（螺動）させるという作業により、定着金物をネジ
鉄筋のセットすべき所定位置まで移動させる必要があ
る。However, when the above-mentioned conventional fixing hardware is set at a predetermined position in the longitudinal direction of the screw rebar, the two nuts or the fixing nut are set as shown in FIGS. It is necessary to move the fixing metal to a predetermined position where the screw rebar should be set by moving (screwing) in the longitudinal direction while rotating.
【０００５】そのため、この従来の両定着金物をネジ鉄

固定するようにしたものである。Therefore, as set forth in Japanese Patent Application No. 5-181044, when the screw rebar is set at a predetermined position in the longitudinal direction, a troublesome operation such as moving while rotating is not required, and the operation can be smoothly performed. Fixing hardware for screw rebar has been invented. FIG. 5 shows an example. However, according to this, the longitudinal movement can be performed by linear movement, but when fixing the fixing hardware to the screw rebar as shown in FIG. 6, a method of driving a wedge or a filling type screw fixing method as shown in FIG. I had to take it. In the present invention, this is further improved so that the fixing hardware is fixed only by twisting rotation without using other materials.

に固定される。The fixing hardware according to the present invention is characterized in that the hole has an inner diameter slightly larger than the screw rebar and a flat portion, and a wedge-type screw groove is formed in the flat portion. . The hole formed by the inner diameter part and the flat part that is slightly larger than the screw rebar becomes a through-hole of the screw rebar, and can be moved in the longitudinal direction of the screw rebar without rotating the fixing hardware. The fixing hardware is twisted and rotated at a predetermined position of the screw rebar, which can be screwed into the screw portion of the screw rebar, so that the screw portion of the screw rebar meshes with the screw portion of the fixing metal. In this case, since the screw of the fixing hardware is formed in a wedge shape, the screw thread of the screw reinforcing bar cuts into the thinned portion of the wedge shape to form a separate wedge as shown in Japanese Patent Application No. 5-181444. It is fixed to the screw rebar without using a filling screw fixing method.

FIG. 2B is a cross-sectional view of the side view of the screw reinforcing bar 3. In the fixing metal 1 of the present invention, as shown in FIG. 1 (b), the cross section of the rebar is formed with a through-hole formed of a circular arc 1 'and a flat portion 1 "which is slightly larger than a threaded bar which can be fitted. Along the hole, the fixing hardware 1 can be freely moved in the longitudinal direction of the screw rebar. The flat portion 1 "of the fixing metal 1 has a screw of the screw rebar 3 as shown in FIG. A screw groove 2 ″ gradually narrowing from the width 3 ′ of the crest is formed. As shown in FIG. 2, the fixing hardware 1 is rotated half a turn at a predetermined position of the screw reinforcing bar 2, and the fixing is performed. The screw groove of the metal fitting 1 and the screw portion of the screw rebar are screwed together, and the thread of the screw rebar is made to bite into the thin portion 3 ″ of the screw groove of the fixing metal 1, thereby fixing the fixing metal 1. A torque wrench or the like may be used for fixing. FIG. 3 shows an example in which the fixing hardware 1 is applied to a beam main reinforcing bar, and FIG. 4 shows an example in which the fixing hardware 1 of the present invention is applied to a U-shaped screw rebar in which threads are arranged at right angles to the bending direction.

The threaded rebar can be penetrated inside without using. Further, the screw portion of the screw rebar and the screw portion of the fixing hardware can be engaged and fixed by twisting and rotating the screw rebar at a predetermined position.
