摘要

本個案木屋屬穿鬥式構架，建於1937年，1966年以29工拆除。所用構件爲紅檜地檻、紅檜或杉木地板樑、柳杉屋柱、柳杉簷枋、杉木或柳杉屋架大樑、闊葉樹材瓜桂、及杉木或柳杉檁條。接合配件除鐵釘外尚有木釘、螺栓、螞蝗釘、及魚尾螺栓：接合方式則有蛇首對接、平口帶榫對接、平斜口對接、燕尾對接、燕搭接、半榫搭接、半榫帶舌搭接、及平榫。構件靜曲強度以屋架大樑保留最多、杉木地板樑最少；以保留之壓縮強度而言，除杉木外之樹種均未降低。

並列摘要

This wood frame house was built in 1937 and pulled down in 1996. Twenty-nine man-days were needed to pull it down. The structural members included Taiwan red cypress sills, Taiwan red cypress and China fir floor beams, Japanese cedar columns and end cross beams, China fir and Japanese cedar tie beams, hardwood species roof posts, and China fir and Japanese cedar purlins. Nails, dowels, bolts, dog irons, and fish plate boils were used as connectors. End joints used included snake head, scarf with tenon, tapered scarf, and dovetail. Lap joints used included dovetail, halved tenon, and halved tenon with tongue. As for the residual bending strength ratio of members, the tie beam had the largest value, and China fir floor beams the least. For the compression strength, all members except those made of China fir retained their original strength.
