Definitions

• said first lateral poition is provided with a face extending substantially parallel to said first face of said at least one elongated body made of expanded plastic material at a predetermined distance therefrom.
• the expanded plastic material of the elongated body carries out the advantageous function of stiffening and of firmly holding in position the reinforcing section bar(s), preventing any deformation of the same as a consequence of the stresses " imparted thereon.
• the reinforcing section bar is further longitudinally extending in the central body of the construction element along substantially the entire length thereof.
• ⁇ the reinforcing section bar is preferably shaped as an L 5 a C, a Z or an I 3 for example by placing two C-shaped elements side by side matching the respective central portions.
• the composite construction element 1 further comprises at least one reinforcing section bar, preferably at least two reinforcing section bars 7, 8, preferably substantially identical to each other, longitudinally extending in the elongated .body 2 and parallel to one another.
• the reinforcing section bars 7, 8 are longitudinally extending in the elongated body 2 made of expanded plastic material at opposite parts of the longitudinal center plane of said body along a direction substantially parallel to said center plane.
• the reinforcing section bars 7, 8 are provided with a central body 7a, 8a, with a first lateral portion 7b, 8b protruding from the face 2a of . the elongated body 2 made of expanded plastic material and with a second lateral portion 7c, 8c essentially incorporated in the elongated body 2.
• the first lateral portions 7b, 8b of the reinforcing section bars 7, 8 are provided with . respective faces 9, 10, preferably substantially planar, extending substantially parallel to the face 2a of the elongated body 2 made of expanded plastic material at a predetermined distance therefrom.
• the rigid panel 11 can be coated at least in part with a fire resistant film, for example obtained from a paint selected from the group comprising intumescent paints and antifire paints.
• the first lateral portion 7b, 8b of the reinforcing section bars 7, 8 is substantially hook-shaped and has in this preferred embodiment a substantially C- shaped end portion.
• the substantially planar faces 9, 10 of the first lateral portion 7b, 8b and the substantially planar faces 13, 14 of the fins (second lateral portions) 7c, 8c of the reinforcing section bars 7, 8 are both substantially perpendicular to the central portion 7a, 8a of the latter.
• the composite construction element 1 allows to achieve improved characteristics of fire resistance thanks to the partial or total coating of the reinforcing section bars 7, 8 with a fire resistant film for example obtained from a paint selected from the group comprising intumescent paints and antifire paints and/or thanks to the use of a covering element incorporating at least one fire retardant material adapted to impart an improved fire resistance, -or of a covering element at least partially coated with a fire resistant film.
• the first-lateral portion 7b, 8b of the reinforcing section bars 7, 8 - preferably essentially constituted by a fairly thin sheet - substantially acts as a spring whenever it engages suitably grooved covering elements connectable in a snap-wise fashion in such first lateral portion 7b, 8b.
• each floor element 19 comprises a central body 19a substantially parallelepipedic, in which a plurality of parallel cavities 24 is longitudinally defined.
• the .floor elements 19 are preferably provided at a lower side with at least one and preferably a pair of longitudinal grooves 25 adapted to house the first lateral portions 7b, 8b of the reinforcing section bars 7, 8, so as to have a firm connection between the floor .elements 19 and the composite construction elements 1 of the floor structure 18.
• the longitudinal grooves 25 are substantially dovetail-shaped with opposite lateral walls tapered in such a way as to firmly hold in the grooves 25, with a substantially snap-wise connection, the first lateral portions 7b, 8b of the reinforcing section bars 7, 8, having in turn tapered lateral portions 16, 17 as better illustrated in Fig. 4.
• the aforementioned operating steps can be carried out without using temporary supports for lengths of the floor structure 18 up to about 2 meters or using a limited number thereof for greater lengths.
• the reinforcing section bars 7, 8 of the construction element 1 are substantially Z-shaped in a manner entirely similar to what has been illustrated in Fig. 8.
• such stretched laths have a thickness comprised between about 0;4 mm and about 1.0 mm and, still more preferably, comprised between about 0.4 mm and about 0.8 mm.
• the step of molding the elongated body 2 made of expanded plastic material is carried out in such a way that the faces 9, 10 of the first lateral portions 7b, 8b of the reinforcing section bars 7, 8 protrude from the face 2a of the elongated body 2 and extend substantially parallel to said face at a predetermined distance therefrom.
