A lintel for windows and doors is provided to make construction easy by manufacturing with lightweight steel wires or reinforcing bars in contrast to the existing lintel for windows and doors which is manufactured with concrete or cement, to have excellent strength against weight by dispersing external force more effectively and to secure structural stability by installing electric wires through a space formed in each member without cutting. Disclosed is the lintel for windows and doors installed in a wall built with bricks or blocks on windows or doors to support an upper structure and to transfer the load from the upper side to right and left walls, which includes a horizontal member(100) composed of a pair of horizontal spacer bars(110) spaced in the horizontal direction and many horizontal connecting bars(120) connecting a pair of horizontal spacer bars and supporting the bricks or blocks placed on the horizontal member not to fall down, a vertical member(200) coupled to the top of the horizontal member vertically and composed of a pair of vertical spacer bars(210) spaced in the vertical direction and many vertical connecting bars(220) connecting a pair of vertical spacer bars and supporting the load of the bricks or blocks built on the vertical member and dispersing the load downward, and a fixing member(300) fixing the horizontal spacer bar not to be slack when bricks or blocks are built on the horizontal member and connecting the top of the vertical member and the right and left ends of the horizontal member. The horizontal spacer bars, the horizontal connecting bars, the vertical spacer bars, the vertical connecting bars and the fixing member are manufactured with steel wires or reinforcing bars to have excellent strength against weight. |
