5/23 発寒の家Ⅲ

 外部のバラ板も撤去し、骨組みが露わになった性能向上改修工事「発寒の家Ⅲ」の現場です。大きな構造の傷みは東側と南側にそれぞれ１か所。中でも南側は柱のみならず土台も一部交換が必要となります。これで傷みの状況がほぼ明らかになったので、今回の状況について建て主さまにご報告して修理の方法を話し合いたいと思います。こっから先は余談になりますが・・・築深の性能向上改修を行う場合は外装がきれいだからと油断せずに土台と胴差廻りくらいは最低限建物一周ぐるりと開口して確認すべきです。くれぐれも構造の傷みを放置したまま上からぺたっ！と断熱を貼るような・・てんぷら工事はNGです。

This is the site of the performance-enhancing renovation work ``Hatsu no Ie III,'' where the external loose boards were also removed and the framework was exposed. There is one large structural damage on the east side and one on the south side. Particularly on the south side, not only the pillars but also some of the foundations will need to be replaced. Now that the damage is mostly clear, I would like to report the situation to the owner and discuss how to repair it. I'll digress from this point on... When performing renovations to improve the performance of a deep building, you should not be careless just because the exterior is clean, but open at least all the way around the building to check the foundation and trunk area. is. I tried to clean it from above without leaving any damage to the structure! Tempura construction work such as putting on insulation is not allowed.

東側、玄関上の大梁の激しい痛みの様子。胴差、梁共い３割程度断面損失。柱頭もぼけて柱表面から深さ20ｍｍ程度は表面が手でめくれます。上下筋交いはきれいに接合部が消失していました。

On the east side, the girder above the entrance appears to be in severe pain. Cross-sectional loss of about 30% for both the trunk and beam. The capital of the column is also blurred and the surface can be turned over by hand to a depth of about 20mm from the column surface. The joints of the upper and lower braces had completely disappeared.

１階の掃き出し窓の上に二階の窓があり、その窓際で漏水。水は胴差と２階梁を傷ませていいます。１階掃き出し窓の際でも漏水が生じたようで両側の柱脚と土台が傷んでいます。

There was a window on the second floor above the sweeping window on the first floor, and water was leaking near that window. The water is damaging the girder and second floor beams. It appears that water leaked near the first-floor sweeping windows, and the pillar bases and foundations on both sides were damaged.
