<p>Floor structures with flooring placed on two parallel screed-board layers. They comprise flooring 10 placed above a lower level of screed boards 6 and an upper layer of screed boards 8, said layers together forming a crossed structure in which the screed boards of the two layers extend perpendicularly with respect to each other. In order to obtain good surface flexibility over the entire floor and, consequently, to make the floor structure suitable as a sports flooring, elastic spring elements 9 are put in position, separating the two layers, at the intersections of the two layers of screed boards 6, 8. Applicable to wooden (parquet) floors used in sports competitions.</p> |
