This article performed analysis of "
Zasiki-hikae" made at the time of construction of
Tuno-zasiki of 1924 and "
Betu-zasiki-hikae" made on the occasion of the building of the
Betu-zasiki of 1929 at the
Inabas house in
Hashimoto city. I considered the way of the wood supply, and it was said that following many points were clear.
In the construction of
Tuno-zasiki of 1924, the wood was supplied from three places of
Simoiti,
Osaka, local
Hashimoto. The materials which it is hard to obtain in
Hashimoto were supplied from
Simoiti and
Osaka. The lumber mill of
Hashimoto provided caudex materials and the amount of payment extended to 93% of wood costs. In other words, the wood supply of the construction of
Tuno-zasiki followed a method of the
Ikenagas detached room construction of 1920. And I can consider that a method to obtain high-quality materials outside local
Hashimoto is generalized.
When
Betu-zasiki was construction in 1929, the lumber was supplied from
Shimoichi,
Osaka,
Kouyaguti and local
Hashimoto. Of these, the lumber supply from
Shimoichi and
Osaka was a choice wood, and the payment to a lumberer of
Hashimoto remained in 43%. In this way, the ratio of materials supply except
Hashimoto is high by the construction of the
Betu-zasiki. In addition, it was the first example of the use of American timber in
Hashimoto on a document. It was a supplier of local
Hashimoto to have supplied American timber with the building of the
Betu-zasiki. They were used at the second-floor beam, long wood mainly on the roof truss and boards. The purchase amount of the American timber is 260.34 yen; the ratio among the wood costs total sum of the American timber 13%, the ratio for caudex materials of the American timber was 20%. The volume of the American timber was a 157.4 cube
shaku. This becomes 32% for the 497.5 cube
shaku that material volume was demanded from.
This article showed that it was generalized to obtain high quality materials in
Osaka with the building with the cityscape of
Hashimoto at the end of the
Taisho era. The same thing was performed in 1929 and was able to confirm the use of the American timber equal to 32% at least material volume, too. It was said that the use of the American timber advanced after the Great
Kanto Earthquake, but was able to confirm that the use of these mainly on caudex materials advanced even to the general house in the town rapidly at relatively early.
