Abstract

PROBLEM TO BE SOLVED: To solve a problem of a conventional tube-like that anchor that is weak because of being made of vinyl without core and is not perfectly inserted into a hole bored in concrete in some cases so that the anchor cannot be fixed unless screwing the screw to the end starting the screwing from the tip, that is a stroke is too long. SOLUTION: This anchor for the concrete 6 has the screw 2 covered with a tube-like vinyl or the like around the screw 2 varied in diameter, pitch or the like along the anchor 6. Thereby, by only fastening the anchor 6 several times, portions 16 are expanded to allow adhesion and fixing of the anchor 6 to a wall face of a hole.

Description of the Related Art A construction method is required in which a hole is made in concrete, a concrete anchor is inserted, a member to be fixed is applied, the hole made in the member is aligned with the center of the concrete anchor, and a screw is inserted. There is a tubular concrete anchor, but it is made of vinyl and has no core, so its waist is weak, it may not fit in the hole made in concrete, and it is necessary to insert screws from the tip and see the end If it is not inserted, it cannot be fixed, that is, the stroke is too long.

にもみこんである為、先に述べたように腰が弱くて入り
きらないとか、ストロークが長すぎるという欠点を克服
できると考えた。As described above, if a concrete anchor in which a screw is embedded is made in advance and a structure capable of being tightened and fixed using the screw can be used, the screw is already embedded. We thought that we could overcome the drawbacks that the waist was too weak to fit or that the stroke was too long.

【課題を解決するための手段】従来の筒形コンクリート
用アンカーにビスをもみこんだ状態で、コンクリートに
開けた穴に挿入して、多少ビスを締め付けても、ビスは
移動するだけで膨張等の変形を起こさない為、固定はで
きない。それはビスが、同じ形をらせん状につなげたも
ので、どの部分の断面を見ても同じなので変化が起きな
いのである。だからネジ山間の幅、ネジ山の形、ビスの
太さを場所によって変化させれば、膨張を起こしコンク
リート壁面に固定することができると考えた。Means for Solving the Problems When a screw is inserted into a conventional tubular concrete anchor, the screw is inserted into a hole made in the concrete, and even if the screw is slightly tightened, the screw moves but expands. It cannot be fixed because it does not cause deformation. The screw is a spiral of the same shape, and no change occurs because the cross section of any part is the same. Therefore, I thought that if the width between the threads, the shape of the threads, and the thickness of the screws were changed depending on the location, they could be expanded and fixed to the concrete wall.

一緒に型での一体形成ができる為安価に提供できる。BEST MODE FOR CARRYING OUT THE INVENTION When a member (13) to be mounted is inserted into a hole (14) formed in concrete, a concrete anchor (5) is inserted and a screw head (15) is tightened with a Phillips screwdriver. The portion of (16) expands and is fixed in close contact with the concrete wall surface. At the same time, as in (17), (13) is pressed against the concrete surface (18) by (15) to be fixed.
The same applies to the concrete anchors (6) and (7). The concrete anchor (8) has a structure in which, when the head of the screw is tightened with a Phillips screwdriver, the portion (19) rises in the direction of the arrow (20) by the action of the reverse screw to expand. The concrete anchor (12) incorporates a plurality of elements of the present invention, and is more efficient because the expanded one is further compressed by rising with a reverse screw. Also (9) or (10)
It does not run idle because the anti-spin components are installed. (9) or (10) is an example of a structure in which a part of the component is caught on the wall surface of the concrete only when rotated in the idling direction, moves to increase the diameter, and stops idling by the friction. When the main body idles by tightening and rotates in the direction of the arrow (21), a part (22) of the rotation preventing component is caught on the concrete wall surface, and when viewed from the main body, it has moved in the direction of the arrow (23). . As a result, the diameter increases and the wheel no longer spins. In this case, parts such as hinges are not used in these cases, and they are only slightly connected at (24). In other words, in the case of manufacturing with a material such as vinyl, it can be provided at a low cost because it can be integrally formed with the cylinder main body in a mold.
