<P>PROBLEM TO BE SOLVED: To provide a wooden structural member capable of reducing a decrease in fire resistance caused by the formation of a through-hole. <P>SOLUTION: A burning stop part 16 is provided around a through-hole 14 penetrating a wooden member 12. The burning stop part 16 suppresses the fire having entered the through-hole 14 in the case of a fire and also suppresses the entry of the heat into the wooden member 12, and the fire stops at the burning stop part 16, which can reduce a decrease in fire resistance caused by the formation of the through-hole 14 in the wooden member 12. <P>COPYRIGHT: (C)2013,JPO&INPIT |
