【考案の詳細な説明】
本考案は横筋通し止めフックを有するアンカーボルトに
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an anchor bolt having a hook for preventing transverse reinforcement.
コンクリート基礎に埋設されたコンクリート基礎の上部
に突出させた上端部に構造体を固定するアンカーボルト
は、一般に、直線状の主杆部の上下端にそれぞれ螺合部
及び鉤部を有するように、太径の丸鋼で成型されている
。Anchor bolts that fix a structure to the upper end of a concrete foundation buried in a concrete foundation protrude above the concrete foundation, generally have a threaded part and a hook part at the upper and lower ends of a straight main rod part, respectively. It is molded from thick diameter round steel.
かかるアンカーボルトは、単に、コンクリート基礎に複
数個−直線上に並列固定させて用いられる場合も多いが
、このようにして用いると、縦筋のみの効果しか具備し
得す、耐震性の面から望ましくないため、各アンカーボ
ルトに横筋を配すことも汎用されている。In many cases, such anchor bolts are simply fixed to the concrete foundation in parallel in a straight line, but when used in this way, they can only provide the effect of vertical reinforcement, which is a problem in terms of earthquake resistance. Since this is undesirable, it is also common practice to provide each anchor bolt with transverse reinforcement.
そして、横筋を配す場合には、通常、アンカーボルトと
横筋とを針金等により結んで固定する手段が採られてい
るが、このような手段は作業性が極めて悪い。When arranging horizontal reinforcements, a method is usually adopted in which the anchor bolts and the horizontal reinforcements are tied and fixed with wire or the like, but such means have extremely poor workability.
本考案は上述の問題点を解消することを目的とするもの
で、下端部に鉤部、上端部に螺合部を有するアンカーボ
ルトの主杆部を一部屈曲させて横筋道し止めフックを形
成したことを特徴とするアンカーボルトを提供すること
により、もって作業性及び耐震性の向上を図ろうとする
ものである。The purpose of this invention is to solve the above-mentioned problems, and the main rod of the anchor bolt, which has a hook part at the lower end and a threaded part at the upper end, is partially bent to create a cross-bracing stopper hook. By providing an anchor bolt characterized by the above-mentioned structure, it is intended to improve workability and earthquake resistance.
以下、本考案のアンカーボルトを図面に示す一実施例に
ついて説明する。Hereinafter, an embodiment of the anchor bolt of the present invention shown in the drawings will be described.
第1図及び第2図はそれぞれ横筋を配した場合の本考案
のアンカーボルトの斜視図及び側面図を示すものであっ
て、両図において、1はアンカーボルト、2は横筋であ
る。1 and 2 show a perspective view and a side view, respectively, of the anchor bolt of the present invention in which transverse reinforcements are arranged, and in both figures, 1 is the anchor bolt and 2 is the transverse reinforcement.
アンカーボルト1は主杆部1aの下端部及び上端部にそ
れぞれ鉤部1b及び螺合部1cを有する。The anchor bolt 1 has a hook portion 1b and a threaded portion 1c at the lower and upper ends of the main rod portion 1a, respectively.
鉤部1bは主杆部1aの上端部近傍までコンクリートに
埋設されたアンカーホルト1の抜止めの機能を有し、ま
た螺合部1cはコンクリートから突出したアンカーボル
ト1に通した構造体(図示せず)を固定するためのボル
ト等を螺合させる機能を有する。The hook part 1b has the function of preventing the anchor bolt 1 buried in concrete up to the vicinity of the upper end of the main rod part 1a from coming out, and the threaded part 1c is a structure (see Fig. (not shown) has the function of screwing together bolts, etc.
本考案のアンカーボルトの特徴は上記主杆部1aを一部
屈曲させて横筋通し止めフック1dを形威した点である
。A feature of the anchor bolt of the present invention is that the main rod portion 1a is partially bent to form a hook 1d for preventing the horizontal reinforcement from passing through.
横筋通し止めフック1dは横筋2を通し止めできる大き
さとし、好ましくは図示の如く上記主杆部1aに複数個
形威し、隣り合う横筋通し止めフック1dで互いに反対
方向に突出させて形成するようにする。The hooks 1d for preventing the passage of transverse bars are sized to be able to prevent the passage of the transverse bars 2, and are preferably formed in a plurality on the main rod portion 1a as shown in the figure, so that adjacent hooks 1d for preventing the passage of transverse bars project in opposite directions. Make it.
上述のように構成された本考案のアンカーボルト1は、
例えば第1図に示す如く並列させ、各アンカーボルト1
の横筋通し止めフック1dに横筋2を配して使用される
。The anchor bolt 1 of the present invention configured as described above has the following features:
For example, as shown in Fig. 1, each anchor bolt 1
It is used by arranging the horizontal reinforcement 2 on the horizontal reinforcement hook 1d.
この場合、横筋道し止めフック1dを交互に反対方向に
突出させれば、図示の如く、上段の横筋2を手前から前
方に、また下段の横筋2を前方から手前にそれぞれ同時
に移動させることにより簡単に横筋2,2を配すること
ができる。In this case, if the horizontal strip stopper hooks 1d are alternately projected in opposite directions, the upper horizontal strip 2 can be moved from the front to the front, and the lower horizontal strip 2 can be moved from the front to the front at the same time, as shown in the figure. The horizontal stripes 2, 2 can be easily arranged.
即ち、横筋2の横筋通し止めフック1dへの保合は、そ
の開口端から横筋2を押し込んで開口端を一旦若干拡げ
、その復帰作用により横筋通し止めフック1d内に横筋
2を係合することにより行なわれる。That is, to secure the transverse bar 2 to the hook 1d for preventing the transverse bar from passing through, push the transverse bar 2 through its open end, expand the open end slightly, and then engage the transverse bar 2 within the hook 1d for preventing the bar from passing through the transverse bar by its return action. This is done by
このように横筋2,2を配した後、アンカーボルト1は
、通常のものと同様に横筋2と共にコンクリート基礎内
に埋設され、その上端部に構造体等が固定される。After arranging the horizontal reinforcements 2, 2 in this way, the anchor bolt 1 is buried in the concrete foundation together with the horizontal reinforcement 2 in the same way as a normal anchor bolt, and a structure etc. is fixed to the upper end of the anchor bolt 1.
また、アンカーボルト1,1は横筋を上記のように交互
に配すことにより、その上端部の螺合部ICの頂部の列
位置を容易に整列させ得る。Furthermore, by alternately arranging the horizontal stripes in the anchor bolts 1, 1 as described above, the row positions of the tops of the threaded portions IC at the upper ends thereof can be easily aligned.
コンクリート内にこのように横筋2を配してアンカーボ
ルト1,1を固定することにより、耐震性の向上が図ら
れるのは当然であが、本考案のアンカーボルト1におい
ては主杆部1aが従来のように直線状ではなく、横筋の
通し止めフックが形成されているから、アンカーボルト
1の廻り止め及び抜は止め効果もさらに向上する。It goes without saying that seismic resistance can be improved by arranging horizontal reinforcements 2 in the concrete and fixing the anchor bolts 1, 1 in this way, but in the anchor bolt 1 of the present invention, the main rod portion 1a is Since the hook is not linear as in the conventional case but has a transverse bar, the effect of preventing the anchor bolt 1 from turning and coming out is further improved.
以上のように本考案のアンカーボルトはその主杆部を一
部屈曲させて横筋通し止めフックを形成したから、横筋
の取付作業の作業性の向上及び耐震性の向上を図ること
ができるだけでなく、アンカーボルトの廻り止め及び抜
は止め効果もさらに向上させることができるものであっ
て、その実用的価値が極めて著しいものである。As described above, since the anchor bolt of the present invention partially bends its main rod part to form a hook that prevents the horizontal reinforcement from passing through, it is possible to not only improve the workability of installing the horizontal reinforcement and improve the seismic resistance. , it is possible to further improve the effect of preventing the anchor bolt from turning and being pulled out, and its practical value is extremely significant.
