Description
【0001】
【発明の属する技術分野】
本発明は、新規なFRP構造体ブロック継手とそれを用いたFRP構造体ブロック及びその縫合装置に関する。
【0002】
【従来の技術】
従来のFRP構造体の継手は、接着接合と機械的接合に大別され、接着接合が広く用いられてきた。FRPは耐水性、耐薬品性に強い特徴をいかした用途が多く、水密性が要求されるため、機械的接合に比べコスト、品質信頼性の両者に優れた接着接合が主流となってきた。
【0003】
寸法的には、陸上輸送可能な最大寸法までが主として接着接合で、それ以上の一部大型品に限り現地で機械的接合あるいは、機械的接合と接着接合が併用されている。
【0004】
【発明が解決しようとする課題】
FRPは30から40年使用され、長期劣化、破損などから新規に代替えせざるをえない構造体も多くなってきたが、形状が大きく、強度も大きいため廃棄処理方法が大きな問題になっている。
【0005】
また、近年、循環形社会の構築や、資源の有効活用、物流コストの低減が強く求められているが、接着接合の大型構造物ではこれに応えることが、困難になりつつある。
【0006】
接着接合を採用する代表的FRP構造体は、舟艇、船舶と大型耐食槽などがある。接着接合はバットジョイント、T型ジョイントが多く、二つのFRP部材を使用しオーバレイアップする。これは危険物の樹脂、硬化材を使用しガラス繊維を積層する湿式接着法であり、熟練作業者を必要とし施工性も悪い。さらに大型構造物は一体化され、FRP接着強度が高いため容易には解体出来ず、大型クラッシャか特殊切断装置が必要である。また解体しても再利用は不可能である。
【0007】
機械的接合を採用する代表的FRP構造体には、ユニットバスと組立て水槽などがある。ユニットバスの上部パネル接合は、外フランジリベット接合を採用するのが一般的であり、軽量で組立て性は良いが、分解は出来ない。
【0008】
組立て水槽は外フランジボルト接合である。FRPフランジは剛性が低いため、フランジ厚さとボルトピッチの最適化を図り水蜜性の向上を図る。また剛性不足の場合はスチール補強部材を併用し締結力及び、負荷の均一性を向上させるため、FRPフランジの増厚、ボルト本数増加、スチール補強部材などから継手関連の重量増は避けられない。固定式水槽は問題ないが、舟艇船舶など軽量化が要求される構造体には適用出来ない。
【0009】
フランジ接合は、外フランジが一般的で、ユニットバスは裏側で見えないが、水槽は目に触れるため外観は良くない。
【0010】
接着接合と機械的接合を併用する代表的なFRP構造体は、火力発電所の排脱装置用スクラバ、ダクトなどである。外フランジボルト接合し且つ、内面はFRP接着接合の併用である。解体には、内側のFRPを除去しなければならず、サンダでの研削作業に莫大な時間を要し、研削作業による粉塵により最悪の作業環境にならざるをえない。また、接合は、接着接合の湿式法で施工性が悪い。
【0011】
本発明の目的は、FRP構造体の一部が劣化、破損した場合の修繕、廃棄を容易に行えると共に、連続した緊張材を巻付け縫合による接合及びその解体が容易で、且つ接合強度の高い継手構造を得ることができるFRP構造体ブロック継手とそのFRP構造体及びその縫合装置を提供することにある。
【0012】
【課題を解決するための手段】
本発明は、繊維強化プラスチックからなるFRP構造体の主板部に、主板部より厚肉に一体にコア部を形成し、該主板部と他の繊維強化プラスチックからなるFRP構造体の主板部とを、各主板部のコア部の端面同士を接触させて機械的に接合するFRP構造体ブロック継手であって、前記各コア部はその厚さ方向に沿って貫通した複数の縫合用連結穴を持ち、前記各コア部に前記各縫合用連結穴を通して連続した緊張材を巻付け縫合して一体化され、前記緊張材の張力により圧縮の状態となる前記コア部の中に接合端面を持つことを特徴とする。
【0013】
前記各コア部は、前記主板部より厚肉のコアと、該コアから前記主板部にかけて徐々に厚さが小さくなる移行部を有すること、又前記連結穴より前記端面に達して設けられた緊張材保護溝を有することが好ましい。又、半円形を基本として構造物の接合構造に応じて接合端面の形状を以下のように設定することが好ましい。

【発明の実施の形態】
(実施例1)
図1は、2枚のFRPブロックを突き合わせて縫合せ締結する場合の本発明のブロック継手の斜視図である。FRPブロック継手は主板に対し主板より厚肉に一体に形成された断面積が増加した厚肉部を有する各コア部を備え、各コア部は、半円筒形コア10と、その半円筒形コア10から主板への移行部11と、半円筒形コア10の厚肉部の端面同士を接触させてFRPブロックを締結する複数の縫合用連結穴12と、縫合用連結穴12間を結び、半円筒形コア10に設けられた縫合用の緊張材14を保護するためのスパイラル状の緊張材保護溝13から構成される。尚、この緊張材保護溝13はなくても本目的を達成することができる。FRPブロック継手は、結合端面がI字型であり、お互い突き合わせた状態で配置し、緊張材14を縫合用連結穴12及び、緊張材保護溝13に添って縫合する。その後、緊張材14を緊張して、FRPブロック継手を締結する。
【0021】
接合部全体は、シール材15を貼付け止水処理もしくは、縫合部の補強を施す。この場合の緊張材14は、たとえばアラミド繊維等の紐材で、充分な引張り弾性強度を持ち、刃物などで簡単に切断できるもので、シール材15は、FRPブロック継手部材及び緊張材14と接着し、水蜜性を発揮でき、且つFRPブロック継手部材及び緊張材14からはく離可能な熱可塑性樹脂材料単独もしくは、これらの樹脂材料と補強材との複合材で構成される。シール材15の貼付けは、シート材15を加熱し熱可塑性樹脂を溶融させた後、加圧して行う。
【0022】
ブロック継手の解体は、再度シール材15を加熱して取り外し、緊張材14を切断することにより、解体できる。
【0023】
図2は、本発明の縫合装置の斜視図及びその縫合方法を示す斜視図である。2枚のFRPブロックを突き合わせて締結する場合の縫合方法の手順は次ぎのとおりである。
(1) FRPブロック継手を、お互い突き合わせた状態で配置する。
(2) 緊張材14の片端に端末金具16を圧着固定する。
(3) FRPブロック継手の縫合用連結穴12及び、緊張材保護溝13に添って連続した緊張材14を巻付ける。
(4) 緊張材14に張力を加える。
(5) ピン治具17を、緊張材14を通した縫合用連結穴12に挿入する。
(6) (3)から(5)を縫合最終端まで繰り返す。
(7) 縫合用連結穴12の最終部において端末金具16を固定する。
(8) 縫合部全体にシール材15を貼る。
【0024】
以下、縫合手順を詳細に説明する。
(2)及び(8)の端末金具16は、ブロック継手の縫合用連結穴12よりも直径が大きい物である。
(6)の動作は、緊張材14の縫合用連結穴12及び、緊張材保護溝13への巻付けと、
張力を加える動作を、1巻き毎に行う。これは緊張材14と縫合用連結穴12、緊張材保護溝13の摩擦抵抗により、巻き初めと巻き終わり張力のばらつきを少なくするためである。
(5)はブロック継手の次の縫合用連結穴12に緊張材14を巻付ける際、縫合を終えた部分での緊張材14のゆるみを防止するためである。
(7)は緊張材14に張力を加えた状態で行い、コア10を圧縮応力状態に保つためである。
【0025】
図3及び図4は、緊張材に張力を加える本発明に係る縫合装置の上面図及び正面図である。縫合装置は、緊張材14が巻回される巻取りリール18、巻取りハンドル34、緊張材14の張力を検出する張力検出部19、巻取りリール18及び張力検出部19が設置され縫合せ方向に移動可能な移動テーブル20、継手の一方を拘束機構によって固定する固定側の固定用テーブル及び拘束機構21と、継手の他方を拘束機構によって固定し縫い合せ面に直交する方向に移動可能な移動側の固定用テーブル及び拘束機構21から構成されている。
【0026】
巻取りリール18は、直接または、歯車、プーリを介し回転可能で、緊張材14を巻付け、手動または、電動機により巻取りリール18を回転し張力を加える。又、電磁クラッチによっても張力を制御することができる。
【0027】
緊張材14に加えられた張力は、張力検出部19で監視し、目標の張力に達した場合、手動または、張力検出部からの信号で、巻取りリールの回転を自動的に止めることによって、張力の制御が可能となる。張力検出部19は張力検出ロール及びロードセルを有し、制御装置によって表示された張力値に基づいて手動又は自動で張力を制御するものである。
【0028】
継手固定用テーブル及び拘束機構21は、FRPブロック継手を表面方向から手動または、油圧、空圧などのクランプにより拘束される。また固定用テーブルの一方は、FRPブロック継手を拘束した状態で移動可能なため、緊張材14で縫合した際、FRPブロック継手のコア部同士が充分密着し、圧縮応力状態となる。これによりFRPブロック継手も安定して拘束できるため、安定した縫合が可能となり、縫合部の品質も向上する。
【0029】
移動テーブル20は、手動または電動機を介して自動的に巻取りリール18、張力検出部19を長手方向、縫合方向に移動できる。これにより巻取りリール18、張力検出部19を待避させることができるため、FRPブロック継手の継手固定用テーブル及び拘束機構21への取付け、取り外しが容易におこなえる。また巻取りリール18、張力検出部19が縫合ピッチ位置に移動可能で、1巻き毎に緊張材14へ加える張力を管理する際、どの縫合個所においても緊張材14と、巻取りリール18、張力検出部19の位置関係が同一条件となるため、張力計測精度の向上が図れ、安定した縫合が可能となる。
【0030】
図5は、シール材貼付けの一実施例を示す断面図である。シール材15はFRPブロック継手縫合部に配置させ、熱風式加熱器22により加熱しシール材15の熱可塑性樹脂が溶融させたのち、回転ローラ23により加圧する。これによりシール材15を皺なく均一にFRPブロック継手縫合部に貼付けることができる。
【0031】
図6は、シール材貼付けの他の実施例を示す断面図である。先のシール材15貼付けの第一の実施例同様シール材15をFRPブロック継手縫合部に配置させ、FRPブロック継手のコア部10と、コア部から主板への移行部11と同一寸法で電熱器24を内蔵した凹型の加圧治具25を押し当て貼付ける。これによりシール材15の熱可塑性樹脂の溶融と、シール材15の加圧が同時におこなえ、作業効率が向上する。
【0032】
本実施例によれば、接合、解体が容易であり、FRP大型構造物であってもブロック化、ユニット化でき、熟練作業者を必要とせず、現地で容易に接合が出来るため、輸送コストと共に、組立てコスト低減が図れる。また継手接合部がFRP構造体の一部が劣化、破損した場合でもその個所のみを取り替え、低コストで、修復が可能となる。FRP構造物の廃棄においても、大型クラッシャや特殊切断装置を必要とせず、クリーンな作業環境で、容易に解体が出来る。解体は、粉砕等で行うものと異なるため、分別廃棄、再利用が可能となる。
【0033】
(実施例2)
図7は、2枚のFRPブロックをL字型に縫合せ締結する場合のブロック継手の斜視図である。実施例1の突き合わせて締結する場合のブロック継手の実施例と同様、コア部26、移行部27、コア部26に貫通した複数の縫合用連結穴28、縫合用連結穴28より接合端面に達したスパイラル状の緊張材保護溝29から構成されるが、コア部25は端面が所望の角度を有する傾斜面を持つ半円筒形状とする。この傾斜面を合せ、先の縫合方向の実施例1と同様に、緊張材を巻付け、張力を加えて縫合せした後、縫合せ全体を前述と同様に熱可塑性樹脂シート材を貼り付けることにより、2枚のFRPブロックをL字型に締結することができる。尚、コア部の傾斜面の角度によりFRPブロックのL字型の角度を任意に変えることができる。本実施例においても前述と同様に、各端面同士を接触させて緊張材で縫合して緊張材の張力により圧縮の状態となるコア部 26 の中に接合端面を持って縫合され、圧縮となったコア部 30 の接合面で、圧縮力による摩擦力が増加する効果が得られる。
【0034】
(実施例3)
図8は、3枚のFRPブロックをT字型に締結する場合のブロック継手の斜視図である。実施例1のI字型突き合わせ、及び、実施例2のL字型に締結する場合と同様に、それぞれ3枚のFRPブロックは、その主板部より厚肉の一体に形成されたコア部30、移行部31、コア部30を貫通する複数の縫合用連結穴32、スパイラル状の緊張材保護溝33から構成される。お互いが突き合わせの状態で、締結される2枚のブロック継手のコア部は、2つ端面が135°の角度を持つV字型の半円柱形状で、もう1枚のブロック継手のコア部は、2端面が90°の角度を持つ半円柱形状とする。この端面を合せ、前述と同様の縫合方法によって、緊張材を巻付け、張力を加えて縫合せした後、縫合せ全体を前述と同様に熱可塑性樹脂シート材を貼り付けることにより、3枚のFRPブロックをT型に締結することができる。本実施例においても前述と同様に、各端面同士を接触させて緊張材で縫合して緊張材の張力により圧縮の状態となるコア部 30 の中に接合端面を持って縫合され、圧縮となったコア部 30 の接合面で、圧縮力による摩擦力が増加する効果が得られる。
【0035】
本発明によれば、緊張材を用いた巻付け縫合による接合、その後の解体が容易であり、FRP大型構造物であってもブロック化、ユニット化でき、熟練作業者を必要とせず、現地で容易に接合が出来るため、輸送コストと共に、組立てコスト低減が図れる。また継手接合部がFRP構造体の一部が劣化、破損した場合でもその個所のみを取り替え、修復が可能であり、その廃棄においても、大型クラッシャや特殊切断装置を必要とせず、クリーンな作業環境で、容易に解体が出来る。解体は、粉砕等で行うものと異なるため、分別廃棄、再利用が可能となる。

BACKGROUND OF THE INVENTION
The present invention relates to a novel FRP structure block joint, an FRP structure block using the same, and a suturing device thereof.
[0002]
[Prior art]
Conventional FRP structure joints are broadly classified into adhesive bonding and mechanical bonding, and adhesive bonding has been widely used. FRP has many uses that have strong features in water resistance and chemical resistance and requires watertightness. Therefore, adhesive bonding superior in both cost and quality reliability has become mainstream compared to mechanical bonding.
[0003]
In terms of dimensions, adhesive bonding is mainly used up to the maximum size that can be transported by land, and mechanical bonding or mechanical bonding and adhesive bonding are used in combination on site only for some larger products.
[0004]
[Problems to be solved by the invention]
FRP has been used for 30 to 40 years, and many structures have to be replaced with new ones due to long-term deterioration, damage, etc., but the disposal method has become a big problem because of its large shape and high strength. .
[0005]
In recent years, there has been a strong demand for the establishment of a recycling-oriented society, the effective use of resources, and the reduction of logistics costs. However, it is becoming difficult to meet this demand with large structures with adhesive bonding.
[0006]
Typical FRP structures that employ adhesive bonding include boats, ships, and large corrosion-resistant tanks. There are many butt joints and T-type joints, and two FRP members are used for overlaying. This is a wet bonding method in which glass fibers are laminated using a resin or a curing material, which is a dangerous material, requires a skilled worker, and has poor workability. In addition, large structures are integrated and FRP adhesive strength is high, so they cannot be easily disassembled, and a large crusher or special cutting device is required. Even if it is dismantled, it cannot be reused.
[0007]
Typical FRP structures that employ mechanical bonding include unit baths and assembled water tanks. The upper panel joint of the unit bath generally adopts an outer flange rivet joint, which is lightweight and easy to assemble, but cannot be disassembled.
[0008]
The assembled water tank is an outer flange bolt joint. Since the FRP flange has low rigidity, the flange thickness and bolt pitch are optimized to improve the water honey property. In addition, when the rigidity is insufficient, a steel reinforcing member is used together to improve the fastening force and the uniformity of the load. Therefore, an increase in the FRP flange thickness, the number of bolts, and the steel reinforcing member inevitably increase the weight related to the joint. There is no problem with the fixed tank, but it cannot be applied to structures that require weight reduction such as boats.
[0009]
The flange joint is generally an outer flange, and the unit bath is not visible on the back side, but the water tank is in contact with the eyes so the appearance is not good.
[0010]
Typical FRP structures that use both adhesive bonding and mechanical bonding are scrubbers, ducts, and the like for thermal power plants. The outer flange bolt is joined and the inner surface is a combination of FRP adhesive joining. For dismantling, the inner FRP must be removed, and the sanding work takes an enormous amount of time, and the dust must be in the worst working environment due to the dust from the grinding work. Further, the bonding is a wet method of adhesive bonding, and the workability is poor.
[0011]
An object of the present invention, deterioration portion of FRP structures, repair when damaged, discarded with the easily, and facilitate continuous tendons joining and disassembly by winding sutures, and highly bonding strength An object of the present invention is to provide an FRP structure block joint capable of obtaining a joint structure, an FRP structure thereof, and a suturing device thereof.
