赤く見える唐松集成材の梁は顕し。それ以外のスプルスの白身材は隠蔽。なので伏せ図のチェックはいつも大変。話は変わるけど・・南部以外は美しい杉の育たない北海道。その代わり松材による集成材や人工乾燥の技術が発達した。おかげで梁の強度はＥ-105以上が最低。高強度材になるとヤング係数はE-150以上にも及ぶ。こんな風にして大黒柱を立てることなく半年間、雪を載せたままにできる大スパンの屋根の強度は得られている。
The red-looking Karamatsu laminated timber beams are clearly visible. The rest of the spruce white meat is hidden. Therefore, it is always difficult to check the hidden drawings. On a different note...Hokkaido, where beautiful cedar trees don't grow anywhere other than the southern part. Instead, laminated pine wood and artificial drying techniques were developed. Thanks to this, the minimum strength of the beam is E-105 or higher. High-strength materials have a Young's modulus of E-150 or higher. In this way, the roof is strong enough to hold snow for half a year without having to become the main breadwinner.
