Abstract
【構成】 被検知部材1の歪を検知する歪センサにおいて、被検知部材1と、被検知部材1に塗料を塗装した塗膜部分2とを有し、塗膜部分2は被検知部材1が所定の値より大きい歪を受けるとひび割れ部分3を生じる。これにより、簡便で安価に歪検知ができ、部材の健全性や地震後等の部材の損傷度を簡単に確認することができる。
【選択図】図1
Description
1.23℃において抗張力が30〜60MPa、伸び率が1〜4%
2.ガラス転移温度が50〜100℃
3.23℃において硬度がHv20〜40
4.膜厚が100〜700μm
また、前記被検知部材又はベース部材と塗膜部分との間に、下塗り塗膜、または、下塗り塗膜および中塗り塗膜を有することを特徴とする。
1.23℃において抗張力が30〜60MPa、伸び率が1〜4%
2.ガラス転移温度が50〜100℃
3.23℃において硬度がHv20〜40
4.膜厚が100〜700μm
前記1の条件にする理由を説明する。前記塗膜部分2は前記抗張力が30MPaを下回ると本来目的とする破断が得られずセンサとしての機能が低下し、60MPaを上回ると非常に軽微な歪で塗膜部分2の破断が生じ本来目的とするセンサ機能が低下する恐れがある。好ましくは35〜55MPaである。また伸び率が1%を下回ると非常に軽微な歪で塗膜部分2の破断が生じ本来目的とするセンサ機能が低下し、4%を上回ると本来目的とする破断が得られずセンサとしての機能が低下する恐れがある。好ましくは1.5〜3%である。
