押圧固定することになる。2. Description of the Related Art For example, a nail used for driving into aerated concrete (ALC) is made by assembling a plurality of legs, connecting each leg with a head and expanding the diameter at the tip of the leg in order to improve pull-out resistance. It has a structure in which the inclined surface of
When it is driven against, the leg opens in the ALC due to the inclined surface of the tip, exerts a retaining function, and presses and fixes the object to be fixed by the head.
【０００３】上記のような開脚釘は、被固定物をＡＬＣ

になる。In the above-mentioned spread leg nail, the fixed object is ALC.
Since it is pressed and fixed against, a head having a larger diameter than the leg is required.
【０００４】図６乃至図８は、従来の開脚釘における頭

ワッシャ２を挿入し、別体に用意した円板状の頭部３を
脚１、１の端部に溶接で固定している。First, in the first example of the head forming means shown in FIG. 6, two separated legs 1 and 1 are combined in a heavy shape, a washer 2 is inserted into this, and a circle prepared separately. A plate-shaped head 3 is fixed to the ends of the legs 1 and 1 by welding.

く頭部８を形成する。A second example of the head forming means shown in FIG. 7 is a split pin shape in which one leg wire is folded in two as shown in FIG. 7A and a circular portion 4 is provided at the bent portion. like,
7C by pressing the circular portion 4 with a flat pressing die 6 while holding the legs 1 and 1 close to the head with the supporting die 5 strongly holding them and pressing the circular portion 4 flatly. The head 8 is formed as described above.

Is pressed by a flat pressing die 6 to deform the folded portion into a flat shape to form a head portion 8a.

【発明が解決しようとする課題】ところで、上記従来の
頭部形成手段において、まず、第１の例は、溶接工程の
必要によって製作コストが高くつくと共に、電流や熱の
管理が複雑になると共に、予め複数の脚を組合せてこれ
を保持しておかなければならず、作業が行ない難いとい
う問題がある。By the way, in the above-mentioned conventional head forming means, in the first example, the manufacturing cost becomes high due to the necessity of the welding process, and the management of the electric current and heat becomes complicated. However, it is necessary to combine a plurality of legs and hold them in advance, which makes it difficult to perform the work.
【０００９】次に、第２の例は、割ピン状の円形部を加

形状になり、このような頭部８は外観的に悪いだけでな
く、打込み時において、頭部８は両側突出部分でワッシ
ャを押圧するだけになり、固定力が弱いという問題があ
る。Next, in the second example, since the circular part having a split pin shape is pressed to form the head 8, the head 8 has a shape protruding only to both sides, and such a head 8 has an external appearance. This is not only bad in terms of performance, but there is also a problem that the head 8 only presses the washers by the projecting portions on both sides at the time of driving, and the fixing force is weak.

る。Further, as shown in FIG. 7, when the head is formed by partially grasping the positions of the legs 1 and 1 near the head when forming the head, the head 8 is pressure-formed. The tips of the legs 1 and 1 are likely to open, which leads to an easy leg opening operation at the time of nailing after assembly, the leg is opened from the initial stage of driving, and the pull-out strength is reduced.

態となり、実質的に頭部としての採用は不可能である。Further, as in the third example, when the bent portion is pressed by a flat pressing die to form the head portion 8a, the pressing force is divided into two in each leg direction to form a long head portion. And not only does the same problem as in the second example occur,
In the bent portion, the extruded top has a thin thickness and is in a fractured state, so that it cannot be practically used as a head.

造方法を提供することを課題としている。Therefore, the present invention provides a nail and a manufacturing method thereof in which the head can be formed in a substantially uniform shape on the outer circumference of the leg without requiring a welding process or a work of combining a plurality of legs. The challenge is to provide.

位置に、脚の外周に張り出す拡径頭部と、この拡径頭部
上に突出する頭部軸とを脚と一体の材料で形成した構成
を採用しもたのである。In order to solve the above-mentioned problems, a first aspect of the present invention is directed to a head-side position where a plurality of legs gather, and a diameter-expanding head projecting to the outer circumference of the legs. The head shaft protruding above the expanded diameter head is formed of a material integral with the leg.

構成を採用したものである。According to the second aspect of the invention, the head side position where a plurality of legs gathers is pressed in the axial direction of the leg with a pressing die having at least a recess for forming the head shaft, and the diameter is expanded to the outer periphery of the leg. Head,
The head shaft protruding above the expanded head is integrally formed with the leg.

一体成形される。When a plurality of legs are held together, the position on the head side is pressed in the axial direction of the legs with a pressing die having at least a recess for forming the head shaft, so that the legs are gathered together. A radially expanded head projecting to the outer circumference of the leg and a head shaft protruding above the head are integrally formed.

できる。Since the expanded head portion is projected outward by plastic deformation of the leg forming material by pressure, it can be formed in a substantially uniform shape on the outer periphery of the leg, and the head shaft is deformed by the recess of the pressing die. When the head is formed in the bent portion of the wire rod formed under the condition that the amount is small, it is possible to prevent the bent portion from becoming thin and flat, and thereby to prevent the head from breaking.

２と一体の材料で形成されている。As shown in FIG. 1, the nail 11 has two legs 1.
The legs 2 and 12 are combined so as to be overlapped with each other, the inclined faces 13 and 13 for opening the legs are formed on the surfaces of the legs 12 and 12 facing the tip portions, and the washers 14 are press-fitted to the outer peripheries of the legs 12 and 12 on the tip side. , The legs 12, 1 at the head-side positions of the legs 12, 12.

The head portion 16 having a circular shaft shape protruding from the upper surface of the
It is made of the same material as 2.

保持するようになっている。The legs 12, 12 are formed by bending a wire rod having a semicircular cross section and having inclined surfaces at both ends into two folds so that the flat surfaces overlap each other, and the bent portions are pressed and deformed in the axial direction of the legs 12, 12. The expanded diameter head 15 and the head shaft 16
1B is integrally formed from the material of the legs 12 and 12 so that the bent portions of the legs 12 and 12 are substantially left at the head shaft 16 to keep the legs 12 and 12 in a continuous state. It is supposed to do.

耐引抜強度を向上させる。FIG. 2 shows a state in which the nail 11 is driven. When the tips of the legs 12, 12 are driven into the ALC 20 from the prepared hole 19 of the object 18 to be fixed, the legs 12, 12 are opened by the inclined surfaces 13, 13. However, the washer 14 blocked the opening of the leg, and in the early stage of the driving, he went straight.
When 4 comes into contact with the object to be fixed 18 and stops, and the amount of penetration of the legs 12, 12 increases, the washer 14 reduces the leg opening preventing force. 13 and 13 leads to open legs on both sides, and at the same time, leg 1
In the ALC between 2 and 12, the thin plate 17 is compressed and bends, and in a completely driven state in which the expanding head 15 contacts the washer 14, the thin plate 17 becomes wedge-shaped between the legs 12 and 12.
Improves pullout resistance.
