Abstract: The fixing metal fitting including: a joint base in groove shape mainly composing a joint metal; a cover spacer in groove shape capable of supporting the pillar's axial load by covering the joint base, wherein joint base including: a plane section in rectangular shape coinciding with an end surface of the pillar; a pair of groove walls bent vertically in L shape; and a joining plate standing from the plane section and supported by welded part J contacting at least the pair of groove walls or groove bottom, wherein the cover spacer including: a plane section in rectangular shape for supporting pillar by abutting to the pillar's end surface; a pair of groove walls composed of side edges of plane section respectively bent vertically in L shape; and a slit drilled such that the joining plate will be fitted into slit when the cover spacer is covering the joint base.

Abstract: A building and construction method include improved workability not causing variation in quality of buildings, by easily joining materials without special processing by forming mortises. A wooden building constructed by fitting horizontal and vertical members includes lower frames, first upper frames, second upper frames, and side joists as horizontal members; and pillars as vertical members, wherein the lower, first upper and second upper frames, and side joists include mortises at part of the lower, first upper and second upper frames, and side joists in longitudinal direction, the first upper frames include an entire length recessed groove in longitudinal direction, the second upper frames include an entire length protrusion in longitudinal direction, the mortises at the lower frames and the first upper frames are through holes, and the pillars include protrusions at both ends, fitting into the mortises at the lower, first upper and second upper frames, and side joists.

Abstract: A construction having generalized and alternative joints, capable of making pillar materials self-stood at in horizontal direction of lower frame materials. Upper and lower frame materials formed by laminating three sawn plates with two or more different plate width in plate thickness direction, and a recessed groove or a protruding stripe of the alternative joints is formed between outer layer plate width of outer layer sawn plates interposing an intermediate layer of laminated layers and an intermediate plate width of intermediate sawn plate interposed as the intermediate layer. The pillar materials are formed by laminating three sawn plates with same length in plate thickness direction, and a protrusion or a recess, which can be fitted closely to the recessed groove or the protruding stripe, are formed at both ends by deviating an intermediate sawn plate in a longitudinal direction for a distance of the difference to outer layer sawn plates.
