Description
【考案の詳細な説明】 〔産業上の利用分野〕 この考案はコンクリート部材に補強材として埋設する
FRP（繊維強化合成樹脂製）ロッドの定着装置に関す
る。[Detailed description of the invention] [Industrial application field] This invention is buried as a reinforcing material in concrete members.
The present invention relates to an FRP (fiber reinforced synthetic resin) rod fixing device.
芳香族ポリアミド繊維（アラミド繊維）や炭素繊維等
を強化材とし、エポキシ樹脂，不飽和ポリエステル樹脂
等を母材としたFRPロッドは強度および引張弾性率が高
く、腐蝕環境に強く、これを用いたコンクリート部材は
耐久性が優れ、海洋構造物等として用い、その優れた特
性が発揮できる。また、アラミド繊維は被磁性体である
ため、磁界の影響を好まない構造物に用い有利である。FRP rods made of aromatic polyamide fiber (aramid fiber) or carbon fiber as reinforcement and epoxy resin, unsaturated polyester resin, etc. as a base material have high strength and tensile modulus, and are resistant to corrosive environment. Concrete members have excellent durability and are used as marine structures and the like, and can exhibit their excellent properties. In addition, since aramid fiber is a magnetic material, it is advantageously used for a structure that does not like the influence of a magnetic field.
この様なFRPロッドはコンクリートにプレストレスを
与える緊張材として用いることにより、その特性を一層
高く発現することができる。しかし、緊張材として用い
るためには鋼材のように定着具を螺着等の手段で取付け
ることはできない。このため、例えば第３図のように、
載頭円錐形を２つ割りした形状の２つの楔形オスコーン
1,1と内部が載頭円錐形の空間２をなし、一端に定着板
３が張出した筒形メスコーン４からなる定着具を用い定

した丸棒状のFRPロッド５を２つの楔形オスコーン1,1間
の中央部に挟み、これをメスコーン４の空間２内に挿入
し、オスコーン1,1のずれを押えながら、両方を固定さ
れるまで徐々にハンマーなどを用い押込み、ロッドを挟
着固定していた。By using such an FRP rod as a tendon for prestressing concrete, its properties can be further enhanced. However, in order to use it as a tension member, it is not possible to attach the fixing tool by means such as screwing like steel. Therefore, for example, as shown in FIG.
Two wedge-shaped male cones with a truncated cone shape
1 and 1 form a frusto-conical space 2, and the fixing is performed by using a fixing tool composed of a cylindrical female cone 4 with a fixing plate 3 protruding at one end. That is, for example, a round rod-shaped FRP rod 5 made of aramid fiber as a reinforcing material is sandwiched in the center between two wedge-shaped male cones 1, 1 and inserted into the space 2 of the female cone 4 to shift the male cones 1, 1. While holding down, the rod was gradually pushed in using a hammer or the like until it was fixed, and the rod was pinched and fixed.
この従来の定着装置では、板状FRPロッド５を２つの
オスコーン1,1間中央に確実にセットすることが困難で
あった。またオスコーンをメスコーンに挿入し、固定さ
れるまでハンマーなどで押込む際に、２枚のオスコーン
がずれて正確に固定しがたく、充分な固定強度を発現す
る上で問題であった。In this conventional fixing device, it is difficult to reliably set the plate-shaped FRP rod 5 at the center between the two male cones 1 and 1. Further, when the male cone is inserted into the female cone and pushed in with a hammer or the like until it is fixed, the two male cones are displaced and it is difficult to fix them accurately, which is a problem in expressing sufficient fixing strength.
この考案は上記問題点に着目しなされたものであり、
その目的はFRPロッドを２つのオスコーン間に正確にセ
ットでき、かつオスコーン間にずれを生じることなく、
メスコーン内に固定ができて、所望の固定強度を発現で
きるFRPロッドの定着装置を提案するにある。This invention focuses on the above problems,
The purpose is that the FRP rod can be set accurately between the two male cones, and there is no gap between the male cones,
An object of the present invention is to propose a fixing device for an FRP rod which can be fixed in a female cone and exhibit a desired fixing strength.
このFRPロッドの定着装置は２つ割りの楔形オスコー
ン間にFRPロッドを挟み、筒形メスコーン内に挿入し固
定してなるFRPロッドの定着装置において、２つの楔形
オスコーンの対向する挟着面に中央のFRPロッド挟着位
置の外縁部に相互に嵌合する突起および嵌合穴を設けて
なることを特徴とする。This FRP rod fixing device is an FRP rod fixing device in which an FRP rod is inserted between two wedge-shaped male cones and inserted and fixed in a cylindrical female cone. The protrusion and the fitting hole which are fitted to each other are provided at the outer edge of the FRP rod holding position.
第１図はこの定着装置のオスコーン1,1であり、載頭
円錐形を中心軸に沿い２つ割りにした形状をなしてい

中央はFRPロッド５の挟着位置６であり、その両外縁の
対向する位置に、それぞれ相互に嵌合する４対の突起７
と嵌合穴８が設けてある。FIG. 1 shows a male cone 1, 1 of this fixing device, which has a shape in which a frustoconical shape is divided into two along a central axis. The axial center of the two opposing clamping surfaces of the male cones 1 and 1 is a clamping position 6 of the FRP rod 5, and four pairs of projections 7 fitted to each other at opposite positions of both outer edges thereof.
And a fitting hole 8 are provided.
この２つのオスコーン1,1は第２図のように、嵌合穴
８に突起７を嵌合して重ね合せ、間にFRPロッド５をセ
ットし、メスコーン４の空間２に挿入し、オスコーン1,
1をメスコーン４内に押込み固定して定着装置として利
用する。As shown in FIG. 2, the two male cones 1 and 1 are overlapped by fitting a projection 7 into a fitting hole 8 and setting an FRP rod 5 therebetween, inserting the FRP rod 5 into the space 2 of the female cone 4 and inserting the male cone 1 ,
1 is pushed into and fixed in the female cone 4 and used as a fixing device.
なお、嵌合穴の深さは、突起の長さより深くしてお
き、オスコーンの挟着面とFRPロッド表面の接触を阻害
しないようにする。また、その位置はFRPロッドの寸法
誤差に対応できるよう、若干の余裕をもった位置とす
る。Note that the depth of the fitting hole is set to be greater than the length of the projection so as not to hinder the contact between the clamping surface of the male cone and the surface of the FRP rod. In addition, the position should be a position with some margin so as to cope with the dimensional error of the FRP rod.
この定着装置は以上の構成からなり、２つ割りした楔
形オスコーンの挟着面には中央のロッド挟着位置の外縁
に相互に嵌合する突起と嵌合穴があるので、突起を案内

正確にセットすることができる。また、２つのオスコー
ンは突起と嵌合穴を嵌合してあるので、メスコーン内に
押込み固定する際に、オスコーン間にずれを生じず、正
確な固定ができる。This fixing device has the above configuration, and has a projection and a fitting hole which are mutually fitted on the outer edge of the center rod clamping position on the clamping surface of the split wedge-shaped male cone. The FRP rod can be easily and accurately set at a predetermined clamping position at the center of the clamping surface. In addition, since the two male cones have the projections and the fitting holes fitted therein, when the male cones are pushed and fixed in the female cones, there is no displacement between the male cones, and accurate fixing can be performed.
以上の通り、この考案の定着装置は、FRPロッドを容
易、正確に挟着固定できるので、FRPロッドをコンクリ
ート部材にプレストレスを導入する緊張材として用い、
その優れた特性を発揮せしめることができる。As described above, the fixing device of the present invention can easily and accurately fix and fix the FRP rod, so that the FRP rod is used as a tension member for introducing prestress into the concrete member,
The excellent characteristics can be exhibited.
