KEY WORD :@architecture / roofing tiles | ||||||
@ | ||||||
The traditional
method of laying or setting tiles on the sheathing *noji
–ì’n of the roof. There are two basic types of tiles to be laid: the broad,
concave tile *hiragawara
•½Š¢, and the semi-cylindrical convex tile *marugawara
ŠÛŠ¢. The latter are also called cover tiles because they are set over the
seams made by the continuous rows of hiragawara. The hiragawara
are laid beginning with the eave edge *nokisaki
Œ¬æ. Problems arise because curves differ on various parts of the roof, for
example the direction of the eave curvature at the eave ends of the roof
and the curvature of the ridge itself. It requires the utmost skill to accomplish
the transition between the two curvatures smoothly. The sheathing is curved
in accordance with the underlying structure, so, the hiragawara must
be evenly placed over the entire surface. If any there is tilt, the roof
will leak. Special problems arise along the drooping verge *minokou
–¥b, and at the corners of the roof. Positioning the semi-circular convex tiles also requires tremendous skill. Seen directly from the front, the convex tiles usually appear in perfectly set lines from eave end to ridge. However, if the same roof is see diagonally looking toward the ridge the concave tiles are visible, and the diagonal line of the tiles should also appear straight. The same is true of a roof covered with pantile *sangawara ŽVŠ¢. The imaginary diagonal line is called karigane Šå‘« (wild goose foot). |
