The present invention relates to a steel lintel beam. More specifically, according to the present invention, the steel lintel beam for windows and doors comprises: at least two or more lower support bars having a curvature to protrude upward and spaced in a horizontal direction; at least one or more upper support bars having the curvature to protrude upward and spaced from an upper portion of the lower support bar; and a truss member connecting the lower support bar and the upper support bar and arranged at constant intervals to divide the lintel to enable a brick or a block to be received between the lower support bar and the upper support bar. According to the present invention, the uses a metal material such as a steel wire and a rebar or a steel plate and uses the horizontal member curved upward in order to increase structural stability although there is deflection after construction. Moreover, the present invention is not easily damaged due to an impact during construction and effectively disperses a load and does not require an additional process due to installation of the extra members such as wiring. |
