［産業上の利用分野］
本考案は、樹脂製の釘の改良に関するものであ

［従来の技術］
建築物の構築や家具等の製作にあたつては、各
部材を接合するために、鉄釘が使用されている。
この鉄釘は、安価であることもさることながら、
打ち込まれてからその表面が酸化し、これによつ
て生じる錆によつて摩擦力が大となつたり、ある
程度、酸化が進むと表面が変形するなどして接合
強度が増加するなどの利点があるために、盛んに
使用されている。[Prior Art] In constructing buildings and manufacturing furniture, iron nails are used to join various members.
This iron nail is not only cheap, but also
After being driven in, the surface oxidizes, and the resulting rust increases the frictional force, and as oxidation progresses to a certain extent, the surface deforms, which has the advantage of increasing bonding strength. It is widely used for this purpose.
ところで、鉄釘の場合、湿度が高かつたりある
いは塩分が多かつたりすると、通常よりも酸化の
スピードが大きくなつて腐食が急速に進み、本来
の接合強度が失われてしまう。 By the way, in the case of iron nails, when humidity is high or salt is present, the oxidation speed becomes faster than normal, corrosion progresses rapidly, and the original joint strength is lost.
そこで、最近では用途に応じて樹脂製の釘も盛
んに使用されるようになつてきている。 Therefore, resin nails have recently come into widespread use depending on the purpose.
［考案が解決しようとする問題点］
しかしながら、この種の樹脂製の釘にあつて
は、ほとんど酸化しないので、釘の表面に十分に
大きな摩擦力が生じないし、変形もしないので、
木材等との馴染みに欠け、打ち込み当初は所期の
接合強度を有していても、接合部が経年的に緩ん
でガタつきを生じさせたり、あるいは釘が抜ける
といつた問題があつた。[Problems to be solved by the invention] However, with this type of resin nail, there is almost no oxidation, so a sufficiently large frictional force is not generated on the surface of the nail, and the nail does not deform.
It lacks compatibility with wood, etc., and even if it has the desired joint strength when it is first driven, there have been problems in which the joint loosens over time, causing rattling or causing nails to fall out.
この考案は、上記のような背景のもとになされ
たもので、経年的にも十分な接合強度を維持する
ことができる樹脂製の釘を提供することを目的と
するものである。 This invention was made against the above background, and the purpose is to provide a resin nail that can maintain sufficient bonding strength over time.

が必要である。[Example] Figures 1 to 3 show an example of this invention, in which reference numeral 1 is a nail made of resin. As a resin material, it can withstand impact when driven with a hammer, etc.
It needs to be strong enough to endure without cracking or breaking, and it needs to be a thermoplastic resin. The nail 1 is composed of a nail body 1a and a head 1b integrally formed with the nail body 1a. A rod-shaped or linear conductive heating element 1c is embedded in the length direction of the nail body 1a. In addition, the material of the conductive heating element 1c must be such that when high frequency is applied, the conductive heating element 1c generates heat by induction heating and can melt the resin part of the nail 1 to some extent. be.

ができる。 Next, how to use the resin nail 1 constructed as described above will be explained. First, furniture or the like is manufactured by driving nails 1 into joints 5a at required locations in the same manner as usual. When all the nails 1 have been driven in, the furniture or the like is heated by induction heating for a certain period of time using a high frequency induction heating device, and the conductive heating element 1c generates heat and melts the resin part of the nail 1. In this case, the longer the heating time, the more the resin will melt, and the shorter the heating time, the less the resin will melt, so the heating time is adjusted depending on the material of the resin, conductive heating element, or plate. This results in
As shown in FIG. 3, a part of the melted resin penetrates into the woody structure of the board 5 and integrates the nail 1 and the board 5, increasing the pull-out resistance of the nail 1 and causing the board to 5.
It is possible to increase the bonding strength between them. especially,
This is effective when the board 5 is made of a material with a rough texture, such as plywood, because the resin easily penetrates into it. Since the nail 1 is made of resin, sufficient bonding strength can be maintained semi-permanently without oxidation or corrosion even in humid or salty locations.

溶かしうる導電性物質であればよい。 The conductive heating element 1 is not limited to the rod-shaped or wire-shaped one as described above, but may also be one formed by mixing a powdered or fibrous conductive substance with a thermoplastic resin and molding it into a nail. The point is that the shape of the conductive heating element 1 does not matter, but any conductive material that can generate heat and melt the resin in a short time when high frequency is applied is sufficient.

久的に維持することができる。[Effects of the invention] In this invention, a nail made of resin is formed by embedding a conductive heating element in the nail body, so that the resin can be indirectly heated and melted by induction heating. Therefore, a portion of the melted resin enters the member to be driven, increasing the pull-out resistance and increasing the bonding strength. Moreover, the surface of resin nails hardly oxidizes, and the desired bonding strength can be maintained semi-permanently.
