Definitions

  • the present invention relates to the general field of the building. It concerns more especially the expanded polystyrene (or interstitial) slabs used traditionally in the manufacture of crawl space floors or tops of basement.
  • the invention also relates to the method of manufacturing this particular slab.
  • Floors of crawl spaces or basements may have expanded polystyrene slabs, obtained by molding or cutting, which are interposed between prefabricated beams arranged parallel to each other other. These beams are generally made of prestressed concrete or lattice metallic. The slabs in question, suitably juxtaposed, provide the formwork and insulation of the floor slab; they are destined to stay at home after pouring the slab.
  • the underside of these expanded polystyrene slabs is covered with an underface layer, which is made of a material intended to prevent the degradation of polystyrene by rodents, and also to improve the insulation characteristics (thermal and sound) of the floor.
  • an underface layer which is made of a material intended to prevent the degradation of polystyrene by rodents, and also to improve the insulation characteristics (thermal and sound) of the floor.
  • corresponding sub-faces consist of fibers mixed with a type binder cement.
  • the present invention aims to remedy these drawbacks by proposing a the underside of which has a reduced thickness and mass, while providing interesting insulation characteristics; the sub-faces in question are very easy to join with the associated polystyrene block and they ensure effective protection against rodent attacks.
  • the slab structure according to the invention consists of a block of polystyrene which is delimited by a lower face, an upper face, two sides of extremities and two lateral sides each provided with an upper longitudinal lug positioning on the receiving beams; and this hourdis is characterized in that it comprises an underside comprising at least one outer layer of metallized material, the thickness of which is between 5 and 100 ⁇ m.
  • this outer layer of metallized material goes back at least partially on both sides of the polystyrene block, and also advantageously on both end sides of this block, so as to cover the less the lower part of said sides.
  • This layer of metallized material reinforces the insulation of the polystyrene block; in particular, it forms a "vapor barrier" structure.
  • This metallized layer is also particularly effective in the context of its anti-rodent function, particularly because of the partial overlap of the lower portions of the lateral sides and ends of the polystyrene block. This layer, very light, does not significantly increase the weight of the slab and it can easily be secured by gluing against the corresponding polystyrene faces.
  • the underside comprises at least one layer of insulating material interposed at least between the underside of the polystyrene block and the outer layer of metallized material.
  • said metal sheet is advantageously entirely coated on its inner face with at least one layer of insulating material.
  • the layer (s) of insulating material used advantageously consist of polyethylene bubble film structures.
  • the outer layer of metallized material is preferably made of aluminum (metal foil and possibly side adhesive strips).
  • the slab structure complies with the invention is of the type devoid of a finishing tongue, and this structure comprises a underside that goes up on substantially half of the height under ears of the sides side.
  • one of the lateral sides of the slab structure is provided with a finishing tongue delimited by a border formed longitudinal free to fit the opposite lateral side of a slab arranged in vis-à-vis, and this structure of hourdis has an underside that goes back at least partially on the longitudinal edge of said finishing tongue.
  • the underside advantageously rises on said longitudinal edge, slightly beyond the angle of the dihedron.
  • FIG. 1 schematically represents a slab made of polystyrene 1, type without finishing tongue, suitably positioned between two beams 2, here simply sketched (in a classical way, the section of the beams is very often T-shaped upside down).
  • the corresponding beams 2 are generally made of concrete prestressed or wire mesh. They are arranged parallel to each other others, with a distance between them adapted for the positioning of the different juxtaposed slabs, to receive a bed of concrete to form including a crawl space floor or high basement.
  • This slab 1 has a conventional general conformation; it consists of a block 1 'of expanded polystyrene, the particular contour is obtained by cutting or directly by molding.
  • the polystyrene block 1 ' is delimited by a lower face 3, an upper face 4, two lateral sides 5 each intended to come opposite a beam 2, and two end sides 6 intended to come into contact with the same slabs. juxtaposed.
  • the two lateral sides 5 each comprise a longitudinal lug 7 arranged in their upper part; these ears 7 form a shoulder 8 adapted to rest on the heels of the beams 2 receiving.
  • the lower face 3 of the slab 1 comprises an attached underside 9, of an original nature, constituted here - a complex formed of an outer sheet 10 of metallized material associated with an insulation layer 11, and - two adhesive strips 12.
  • the outer sheet 10 is preferably an aluminum foil, the thickness of which is between 5 and 100 ⁇ m.
  • the insulating layer 11 consists of a polyethylene bubble film. This insulating layer 11 may have a thickness of between 2 and 60 mm; she is made from a polyethylene sheet 20 to 300 ⁇ m thick.
  • the protective complex 10, 11 of the underside 9 can advantageously be prepared in advance by joining the aluminum foil 10 with the bubble film 11; it may be packaged in roll for transport or storage.
  • the protective complex 10, 11 is cut into suitable dimensions to completely cover the lower face 3 of the polystyrene block 1 '.
  • the complex 10, 11 is cut in a rectangle whose width corresponds to the distance between the two end sides 6 of the block 1 ', as can be seen in Figure 3.
  • This complex 10 , 11 is further cut so that its length is greater than the distance between the two lateral sides 5 of the polystyrene block (FIG. 2), so that said complex rises about half of the height under the ear 7 of said sides 5. returns 15 of the complex thus formed, as shown in detail in Figure 2, each face a side face of beam 2, and thus mask all the part of the lateral side 5 may be degraded by rodents.
  • the lower protection of the polystyrene block 1 ' is finalized by the laying of the metallized adhesive strips 12, attached to the angles formed by the lower face 3 of the polystyrene block 1' and the end sides 6, as shown in the figures 1 and 3.
  • the metallized strips 12 are fixed so as to extend partly on the end sides 6 and partly on the outer face of the metallized sheet 10. It can still be seen in FIG. 1 that the two ends 16 of the adhesive strips 12 extend at the two lateral sides 5, in order to optimize the masking of the lower part of the polystyrene block 1 '. These adhesive strips 12 thus constitute the return of the underside 9 for the two end sides 6.
  • the adhesive strips 12 are advantageously made of aluminum and their thickness is between 5 and 100 ⁇ m.
  • the use of the metallized outer sheet 10 and metallized adhesive strips 12 forms a protective layer which covers the lower face 3 of the polystyrene block, and also the lower parts of the lateral sides 5 and ends 6.
  • This layer external metalized material 10, 12 prevents rodents from degrading the block of polystyrene; it also provides enhanced thermal insulation, in particular its thermoreflection and vapor barrier properties.
  • the combination of the insulation layer 11 with the metallized sheet 10 increases the strength of this metallized sheet 10, and also improves the characteristics thermal insulation of the slabs equipped.
  • the bubble film 11 allows on the other hand to absorb the pressures or shocks subjected to the metallized sheet 10, in particular where it is necessary to use underlying shoring structures for the casting of the concrete bed.
  • the protective underside 9 negligibly modifies the thickness and the weight equipped hoard. These slab structures are therefore easily manipulable and, ultimately, significantly limit the dead weight of the floor.
  • the various constituent elements of the soffit 9 can in addition very easily be secured to the underside and sides of the polystyrene block, by their nature and their flexibility characteristics.
  • Figures 4 and 5 show a variant of expanded polystyrene slab 20, according to the invention, here of the type conventional finishing tab, that is to say comprising a lateral tongue 21 intended to be positioned under the beams in order to achieve aesthetic continuity and improve noticeable both thermal and sound insulation.
  • FIGS. 4 and 5 show a conventional slab structure of an expanded polystyrene block 20 'delimited by a bottom face 3, a face of 4, two end sides 6 and two lateral sides 5. These two lateral sides 5 have longitudinal lugs 7, and one of them has the finishing tongue 21, mentioned above, in its lower part.
  • the polystyrene block 20 ' is also provided with relief recesses classics 25.
  • finishing tongue 21 has a longitudinal edge free 22 which is shaped dihedron, with an angle or edge marked 23 ( Figure 5).
  • This longitudinal edge 22 is structured to match the opposite lateral side 5 of a identical hourdis positioned opposite.
  • the protective complex 10, 11 is here cut so that its length is sufficient to form a return 15 at the free longitudinal edge 22 of the tongue 21, and also on the opposite lateral side 5. More specifically, the return 15 provided for in level of the tongue 21 has a length sufficient to go back at least slightly beyond the edge 23 of the longitudinal edge 22 dihedron.
  • the protection is finalized, as in the previous embodiment, by the application of metallized adhesive strips 12 (preferably made of aluminum), on the length of the angles formed by the end sides 6 and the lower face 3 of the block polystyrene 20 '.
  • metallized adhesive strips 12 preferably made of aluminum
  • This slatted tongue structure 21, thus equipped, is particularly well protected against rodent-related damage and has reinforced thermal and sound insulation.
  • Such slabs 20 are on the other hand very easily manipulated due to the still negligible influence of the underside 9 on their thickness and weight.
  • the underside of protection 9 can fully include an insulating structure consisting of a superposition of several bubble films.
  • the insulation layer may be removed, the protective underside then being made of only one sheet of metallized material secured to the underside 3 of the polystyrene block equipped, possibly associated with peripheral extensions, for example in the form of metallic adhesive strips, to cover the lower part of the sides side and end of this block.
