FIELD: construction industry.

SUBSTANCE: invention relates to the field of construction, more specifically to the method for floor board topping. The method for floor board topping includes the installation of metal joists on the floor beams having a “hat” or “omega” profile in cross section. Perpendicular to the joists, a floor board of the 1^st row is installed without the possibility of displacement along the joists. Next, a board of the 2^nd row is installed with pre-drilled holes, into which spring blocks are installed, consisting of a screw-on hardware with a head, and a combined compression-torsion spring strung on it. Each spring is positioned in the hole so that the protruding part of one of the supporting turns engages with the profile of the joist, after which the boards are fastened by screwing the hardware through the body of the board of the 2^nd row into the body of the board of the 1^st row, then the boards of the 3^rd and subsequent rows are installed similarly, repeating the operation until the flooring is completely laid.

EFFECT: exclusion of gaps between the floor boards.
