- the metal sections 30, 40 having a straight Z section comprise a core 31, 41 and a sole 32, 42 at the upper end of the core and a sole 34, 44 at the lower end of the core; the soles are in practice substantially perpendicular to the core 31, 41 and extend transversely in opposite directions.
- a return 33, 35, 43, 45 is disposed at the free end of each of the flanges 32, 34, 42, 44.
- the return 35, 45 of the lower flanges is housed in a slot or notch 21A, 21 B presented in the lower face 21 of the interjoists 20.
- each lower sole 34, 44 and that of the core 31, 41 respectively wedge the edge or marginal portion of the underside 21 of the interjoists 20 and the longitudinal side or edge 23, 24 20.
- the inner surface of the core 31, 41 is welded or glued by an adhesive adapted to the longitudinal side or edge 23, 24 of the interjoists 20 to ensure the joining of the profiles to the interjoists.
- the core 31, 41 is welded or glued to the longitudinal side or edge 23, 24 over its entire height.
- the core 31, 41 may be welded or glued continuously along its entire length or in places.
- the inner surface of the lower flanges 34, 44 may also be secured by welding or gluing to the edge of the underside 21 of the interjoists 20. It may be the same between the upper surface of the sole 42 with the lower face 26 of the shoulder 27 of the interjoists 20.

- the inner surface of the profiles and more particularly the inner surface of the core 31, 41 is secured by welding to the longitudinal side or edge 23, 24 of the interjoists and possibly the inner surface of the lower flanges 34, 44 or the inner surface of the returns 35, 45 with a corresponding wall of the slot or notch 21 A, 21 B.
- the profiles of the modular elements and interjois modular elements juxtaposed can be placed and fixed directly on the load-bearing walls, or on the beams attached to the walls, as shown in Figure 11.
- an opening can be practiced in a central portion of such a dry floor to be able to pose a staircase between two levels.
- the modular elements of the dry floor on either side of the opening are shortened and interconnected by transverse profiles forming the opposite edges of this opening in the dry floor and ensuring the maintenance of these shortened modular elements and the integrity of the dry floor.
- the metal profiles both have a straight Z-section but one of them and the profile 30 have slightly larger dimensions, in particular the core 31 being higher than the core 41 and the sole 32 wider than the sole 42.
- the prefabricated modular elements can be delivered on site ready for mounting in dry floor.
- Such modular elements have a relatively low weight allowing the installation by two workers without help lifting equipment or other heavy equipment.
- These modular elements are placed side by side, the sole 32 of the profile 30 bearing on the sole 42 of the profile 40 as shown in Figure 2. Since the profile 30 is slightly larger than the profile 40, the sole lower 42 and its return 43 fit between the core 31 and the return 33 of the profile 30 juxtaposed interjoists. Similarly, longitudinal edge 25 of the shoulder 27 is in abutment with the longitudinal edge 23A of the interjoists 20 of the modular element 10 juxtaposed.
- One and / or the other ends of the flanges 33, 43 are preferably fixed by means of bolting or screwing to the load-bearing wall or the support beam on which the modular elements are placed.
- the soles 33, 43 may be perforated for this purpose.
- a bore (not shown) may pass through the interjoists shoulder 27 for screwing, bolting or riveting and then filled by a suitably shaped plug of the same material as the interjoists or other filling material, so that to reconstruct the continuity of the upper face 22.
- the anchoring profiles at one end is advantageous since it allows the expansion of the profiles without producing stresses or deformations of the dry floor.
- the dry floor which results from the assembly of the modular elements 10 is a monolithic assembly, which comprises an upper surface defined by the upper face 22 of all the modular elements and is substantially continuous and plane.
- a concrete screed a few centimeters thick (typically 4 to 6 cm) can still be poured on the upper surface of the dry floor.
- suitable gypsum plasterboard such as PLACOSOL ® gypsum plasterboard from PLACOPLATRE are attached to the interjoists to receive the coating.
- a rod or spar also made of expanded plastic material including expanded polystyrene or polyurethane rectangular section and dimension corresponding to that of the rectangular cavity defined by webs 31, 41 opposite and the sole 42 is inserted and secured in particular by bonding to the outer surfaces of the profiles forming the cavity.
- the chords or side members must be attached to one of the sections before laying modular elements.
- the outer surface of the flanges of the profiles 34, 44 are substantially at the same level of the lower face 21 of the interjoists 20.
- the edges of the lower face 21 of the interjoists may be slightly set back from the underside of the interjoists between the slots 21A, 21B so that when the profiles are secured to the interjoists, the outer surface of the flanges 34, 44 is substantially in the plane of the central portion of the lower face of the between the slots 21 A, 21 B.
- the modular elements 10 are oriented so that the face 22 of the interjoists 20 is the upper face. But it is also possible to assemble modular elements in the opposite direction. Thus with such an orientation, the upper surface is defined by the face 21 of the interjoists 20 and the outer surface of the flanges 34, 44 and the lower surface of the modular element by the single face 22 of the interjoists.
- the dry floor made from the modular elements thus inverted would have the advantage of facilitating the introduction of rods or spars between the profiles of two modular elements juxtaposed since the introduction of the rod or spar can be made after the installation of the modular elements without access to the lower surface of the dry floor. But such a dry floor will have a lower mechanical strength since the soles 34, 44 do not serve as a support for interjoists and the maintenance of the whole is ensured exclusively by the joining of the profiles at the sides or opposite edges of the interjoists .
- the shoulder 27 of the interjoists is eliminated, the longitudinal edge 24 extending from the underside to the upper face of the interjoists.
- rods corresponding to the dimensions of the shoulder 27 are inserted and secured in the empty between the interjoists of two modular elements juxtaposed after the laying of the modular elements, especially when the modular elements are oriented as shown in Figure 2.
- FIG. 4 illustrates a variant of this first embodiment in which a plate 60, such as a PLACOSOL® plasterboard for laying a floor covering, is fixed on the upper surface of the interjoists 20.
- a plate 60 such as a PLACOSOL® plasterboard for laying a floor covering
- Such a plate can be fixed by any means including riveting, stapling, screwing or bolting.
- a lower plate 50 may be attached to the underside 21 of the interjoists 20 and / or the outer surface of the flanges of the profiles.
- a modular element according to this variant of the first embodiment allows an even faster installation since the upper surface is ready to receive the floor covering and the lower surface does not require any other preparation.
- the upper surface of the modular element and therefore that of the resulting dry floor is formed by the upper face of the interjoists 20.
- This interjoists thus comprises an upper portion 28 which extends above the level upper flanges 32, 42. This is not necessarily the case. Indeed, in a non-illustrated variant of this first embodiment, the upper portion 28 of the interjoists is removed and the upper surface of the interjoists is substantially at the same level as the outer surface of the upper flanges 32, 42.
- FIGS. 5 and 6 A second embodiment of the modular dry floor element of the present invention is illustrated in FIGS. 5 and 6.
- the two metal sections, secured to the longitudinal edges of the interjoists, do not have the same section.

- This connection preferably concerns at least the core 131 and the longitudinal edge 124, if any, the flanges 132, 134 and the marginal part of the upper and lower face 122, 121 of the interjoists.
- the C section section with returns should normally be mounted by relative longitudinal sliding of the profile 130 relative to the marginal portion of the between 120 while the right Z or U profile can be introduced transversely.
- the assembly can also be performed by rotating such a profile at the intersection of the return 35 and the sole 34. To do this, the height of the marginal portion of the upper face above the bottom level of the notch or notch 122B may be reduced to facilitate the passage of the return 33 when rotating to the notch or notch 122B.
- the sole 132, and in practice the flanges 132, 134 should have a width slightly smaller than that of the upper flange 142 of the section 140.
- FIG. 6 The assembly of two modular elements 110 is illustrated in FIG. 6.

- This median lower part forms a 120A panel of a height determined according to the desired acoustic performance, and made of mineral wool, glass wool or rock wool.
- the panel can be glued or otherwise fixed in the reserve defined for this purpose in the lower middle part of the interjoists 120.
- the panel could extend over all or part of the length of the interjoists.

- Figure 9 shows a variant of the form of the third embodiment of Figures 7 and 8. In this variant, the lower face of the modular element 210 is packed.
- a plate 150 in practice a gypsum board such as a plasterboard PLACOSOL ® , is fixed by gluing or by mechanical fixing means to the interjoists 220 or even to the lower flanges 44, 134.
- This plate 150 can then be coated with a layer of plaster 155 or other to form a ceiling of the room or room under the dry floor.
- This lining may be applied at the time of manufacture of the modular elements or during installation and in this case it may extend under a plurality of modular elements.
