Abstract
【課題】 白蟻の食害によって発生した蟻道の存在を、外部から、簡単かつ非破壊で検査する。
【解決手段】 白蟻による食害を受けると蟻道2ができ、この蟻道には糞や食べかすなどの廃棄物が付着していて、この廃棄物は吸水性で、かなりの水分を含んでいる。そこで、被検査材1の側面に、高周波水分計3の接触片4を宛てがい、被検査材1の内部、深度40〜60mm程度までの含水率を測定する。この測定含水率値と、予じめ測っておいた正常な部材の含水率値とを比べ、異常に高ければ、その測定箇所の内部に蟻道2が存在すると判定する。

Claims (2)
- 被検査材に高周波水分計を宛がい、被検査材の内部の含水率を測定し、この測定値が、予じめ測っておいた正常な部材の測定値に比べて、異常に高い時に、被検査材の内部に蟻道が存在すると判定する、白蟻の蟻道検査方法。
- 被検査材の外表面に、携帯式の高周波木材水分計の接触片を宛がい、被検査材の内部の少なくとも深度40mmまでの範囲の含水率を測定する、請求項1記載の白蟻の蟻道検査方法。
