100年古民家 淡輪山荘の土台の修復がスタート、不良部分を切り取って入れ替える
100年古民家 淡輪山荘の土台の大引きの修復は、不良部分だけを切り欠いて入れ替える「鎌継ぎ」という方法と、大引1本丸ごと入れ替える方法の2つ。先日のチェックで、それは既に区分けされています。その指示に従って、大工さんたちが迅速に作業していきます。
ちなみに鎌継とは鎌継ぎは、鎌の刃のような形状のほぞを差し込むことで、より強度を高め、特に引っ張りに対して強度をもたせるというもの。
問題がなかった土台部分には床板が貼られていく。あっという間の出来上がりに驚きです。
Reconditioning work of the foundation of the 100-year-old house, has literally started, at first place, cutting out the sections for replacing defectives.
There are two ways to repair the foundation joists of Tannowa Sanso: cutting out and replacing only the defective parts, called "Kamatsugi," and replacing the entire joist from end to the end. Which to apply of these methods has already been decided during the said inspection. Then the carpenters work quickly according to the instructions.
By the way, Kamatsugi is a method of inserting a tenon shaped part to narrow navel part to make the material as if one piece and then increase strength, especially against pulling tension.
Floorboards are then fixed onto the joist with that completely refreshed floor bed. Watching carpentars movement just a minute and you'll find it how amazingly they proceed whole works.
