Description
【考案の詳細な説明】 本考案はアンカーボルトに関するものである。[Detailed explanation of the idea] The present invention relates to an anchor bolt.
アンカーボルト20は、上端筋2、補助筋3、
下端筋4等の横筋と縦方向の助筋5とを交換させ
た配筋構造をメタルフオーム等の仮枠7で囲み、
メタルフオームの天端にアンカープレート8で支
えられて配設され、コンクリートの流し込みによ
つて基礎9に固定される。 The anchor bolt 20 includes an upper end reinforcement 2, an auxiliary reinforcement 3,
The reinforcement structure in which the horizontal reinforcements such as the lower end reinforcements 4 and the vertical auxiliary reinforcements 5 are replaced is surrounded by a temporary frame 7 made of metal foam, etc.
It is disposed at the top of the metal form supported by an anchor plate 8, and fixed to the foundation 9 by pouring concrete.
この様な従来工法において、天端からのアンカ
ーボルト20の突出部分11は短かいために基礎
に鉛直に突出しているか否か判別しにくく、又、
アンカープレートの一点において支えられるため
コンクリートの流し込みにおいてアンカーボルト
の突出部が振れ動き、これがために基礎に固定し
た後において、アンカーボルトが鉛直方向からず
れ傾いていることを発見することがある。 In such conventional construction methods, the protruding portion 11 of the anchor bolt 20 from the top is so short that it is difficult to determine whether it protrudes perpendicularly to the foundation or not.
Because the anchor bolt is supported at one point on the anchor plate, the protruding part of the anchor bolt swings during pouring of concrete, which may cause the anchor bolt to be found to be tilted away from the vertical direction after being fixed to the foundation.
この様なずれ傾きや、それによる配設寸法誤差

すると共に、嵌合後におけるボルトの締付けをも
困難にし、且つ又、ワツシヤーを介してのボルト
の締付けにおいて、ボルトとワツシヤーとの間に
隙間が生じて確実に締付けられない。 Such deviation and inclination and resulting dimensional errors make it difficult to fit the anchor bolt to the required member, and also make it difficult to tighten the bolt after fitting. When tightening the bolt, a gap occurs between the bolt and the washer, making it impossible to tighten the bolt securely.
特にこの様な配設寸法上の誤差は、二つのアン
カーボルトの間隔が接近する場合、具体的には組
立家屋等のパネル構造物の衝合せ端の下方におい

定する場合に問題になる。 In particular, such errors in installation dimensions occur when the distance between two anchor bolts is close to each other, specifically when fixing to an anchor bolt below the butting end of a panel structure such as a prefabricated house, This becomes a problem when two reinforcing steel columns are brought into contact and fixed to their respective anchor bolts.
本考案は、かかる不都合を解消するものであ

て構成される。 The present invention is intended to eliminate such inconveniences, and will be explained with reference to the embodiment shown in FIG.
2, 12' is bent into a U-shape so that at least the threaded parts 12, 12' at both ends are parallel, and the intermediate parts 13, 13' located below the threaded parts are Connecting bars 15 are joined by spot welding or the like in the direction perpendicular to the threaded portion, and
It is constructed by bending both ends 16 and 17 of the connecting rod in opposite directions within a plane perpendicular to the threaded portion including the connecting rod.

させて配設される。 This anchor bolt 10 has one bent end 16 of a connecting reinforcement 15 mounted on a transverse reinforcement 2 having a reinforcement structure surrounded by metal foam, and the other end side 1 of the connecting reinforcement 15
The connecting bars 15 are tied to the horizontal bars 2 near the joints 7, and an anchor plate 8 with threaded portions 12, 12' projected is mounted on the top end of the metal form 7.

に起因する不都合は悉く解消される。 As is clear from this, the two screw parts 12 and 12' protrude from the top of the concrete foundation that has been cast.
is the locking part 14 and the connecting bar 1 at the U-shaped bending point.
5, and there is no dimensional placement error between them, and since the horizontal reinforcement 2 and the connecting reinforcement 15 are fixed in parallel, the threaded portions 12, 12' are connected to the horizontal horizontal reinforcement 2. Since they are reliably orthogonal and fixed at two points, the transverse reinforcement 2 and the anchor bolt 8, there is no wobbling movement of the threaded parts 12, 12' when concrete is poured, and thus the threaded parts are securely attached to the concrete foundation 9. It is fixed in the vertical direction. Therefore, all the inconveniences caused by displacement and inclination of the anchor bolt that have conventionally occurred are eliminated.
更に又、横筋との一回の結束により実質的に二

に解消する。 Furthermore, since two anchor bolts are essentially fixed to the horizontal reinforcement by one binding with the horizontal reinforcement, the workability of the foundation work is improved. Furthermore, the total length a'+b' of the protrusions of both ends 16 and 17 is taken as the base thickness h, and by inserting and abutting the tip of this protrusion between the metal forms, it is essentially fixed at four points, The inclination of the anchor bolt is more reliably eliminated.

に固定される。 In addition, as shown by the two-dot chain line in Fig. 2, in a reinforcement structure in which two horizontal reinforcements 2', 2'' are arranged in parallel with an interval b slightly larger than the interval between the two threaded parts, the connecting reinforcement It is also possible to install an anchor bolt by placing both ends 16 and 17 of the horizontal reinforcement on the two parallel horizontal reinforcements. ″, the anchor bolt is securely fixed at right angles to the transverse reinforcement.
即ち、本考案の効果は、二つのネジ部を横筋の

る。 That is, the effect of the present invention is produced in the same way when the two threaded portions are fixed in parallel to the length direction of the transverse reinforcement, and when they are fixed in a direction perpendicular to the length of the transverse reinforcement.
