PROBLEM TO BE SOLVED: To effectively use thinnings of Japanese larch and the like, install a green log as it is, to reduce burden as labor, to reduce days for the execution of works and to reduce cost. SOLUTION: The center lines of each log 6 are arranged horizontally, and a plurality of the logs 6 are piled up in the vertical direction. Grooves 7 are formed along the center lines of the logs 6 in the vicinity of mating surfaces with the adjacent logs 6 of each log 6, and common connecting members 8 are fitted and connected to the mutually faced grooves 7 in the adjacent mutual logs 6, thus constituting a log wall 5. The log 9 is erected vertically to constitute a column, and the log walls 5 are arranged and crossed in the two directions of the log column 9. Each log 6 constituting the log walls 5 is connected to the log column 9 by using bolts 10 and nuts 11. COPYRIGHT: (C)2005,JPO&NCIPI
