The vertical plates of side walls of the beams have toothed protrusions above vertical contour in the plane of plate of a thickness equal to the thickness of plate, and which height does not reach the value of the plate thickness of the side wall. The horizontal, inclined and vertical plates of upper and lower walls have dents in front of the protrusions in the vertical plates, with which they are joined, in which when connecting the vertical plates of side walls with other plates the protrusions of vertical plates are installed.
