The purpose of the invention is to improve the behaviour and<br />
general stability of the roof under the action of loads<br />
(vertical and horizontal), to reduce material consumption and<br />
to simplify the assembling. The invention relates to modern<br />
girders with spatial structure, at which upper flange is<br />
composed of a reticulated network (a rhombus shape) of<br />
laminated standardized beams made from wood, steel or<br />
reinforced concrete. The lower flange and the diagonals are<br />
in a ”V” shape made from steel, having a static scheme<br />
which allows a better distribution of loads, respectively of<br />
stresses (strains), in comparison with the conventional<br />
construction solutions. Lightweight roofs made of modern<br />
girders with spatial structure according to the invention have<br />
the advantage of industrial execution and a reduced<br />
consumption of materials, and due to their reduced weight,<br />
their installation is simple and without problems, which leads<br />
to a considerable shortening of the period of execution and<br />
costs in comparison with conventional solutions.<br />
