The present invention relates to a framing rafter forming a frame of a roof having inclined sides, the roof of a Hanok or a timber house. The rafter of the present invention is formed into a ′ㄷ′ shape by forming engraved grooves at constant intervals on the top side, forming inclined side parts at both sides thereof, which spreads wider toward bottom end parts, and forming protrusions or grooves at a bent edge parts of the top side and the inclined side parts. If a work load is applied to the top side, the edge parts and inclined side parts can firmly support by absorbing the load. Thus, the rafter can remarkably improve construction efficiency as well as the convenience in assembling of roof inclined sides. |
