The work begins with punching through nests for the launch and installation of beams through them. Between the upper shelf of the beams and brick masonry, a board is laid a thickness of 7 mm, since with a slight deflection of the beam, the edges of the brickwork may occur. These beams are installed at a certain distance from each other according to the calculation produced, but not less than 0.75 m, given the necessary convenience of work. Typically, under every two adjacent ends of the beams, one auxiliary foundation from a sleeper cage is displayed (FOT. 470).
