Definitions
- the present invention relates to the building sector and in particular to the construction of reinforced floors.
- floors made of expanded material with metal reinforcement which are characterized in that an expanded mass is envisaged semi-embedded in which are the lattices of the reinforcement having top portions without expanded material.
- the main purpose of the present invention is to overcome the above drawbacks by providing an innovative method for assembly and construction of floors at ambient temperature.
- the method that is described enables use of metal reinforcements that are also appropriately treated against corrosion.
- a hybrid structural element for the construction of a horizontal or inclined floor for residential and industrial use with unidirectional reinforcement or bidirectional reinforcement (criss-cross structure), said floor being made up of expanded insulating material, inserted in which are metal reinforcements, such as for example lattices of the baustrada type 2 or other type, metal girders 3 with IPN, IPE, HEA, HEB profiles or the like, and re-rods 4.
- metal reinforcements such as for example lattices of the baustrada type 2 or other type, metal girders 3 with IPN, IPE, HEA, HEB profiles or the like, and re-rods 4.
- the structural element is constituted by insulating material 1, such as for example, but not exclusively, expanded polystyrene (referred to also as “polystyrene foam") having a shape with plane development, in which longitudinal grooves SL are provided, where the metal reinforcements 2, 3, 4 are inserted in order to constitute a kind of formwork, in which said metal reinforcements are present during preparation and construction of the floor in situ ( Figure 2 ).
- insulating material 1 such as for example, but not exclusively, expanded polystyrene (referred to also as "polystyrene foam") having a shape with plane development, in which longitudinal grooves SL are provided, where the metal reinforcements 2, 3, 4 are inserted in order to constitute a kind of formwork, in which said metal reinforcements are present during preparation and construction of the floor in situ ( Figure 2 ).
- the aforesaid reinforcements provided during assembly in the factory, can be integrated with further reinforcements prepared in situ prior to casting of concrete.
- the longitudinal grooves SL preferably have a cross section with a substantially symmetrical trapezial shape.
- the grooves provided in the insulating material 1 for insertion of the metal lattices 2 have an inverted-V cross section and are designed to be filled, after insertion of the reinforcement 2, with further insulating material I, such as for example foam or other suitable material.
- the top part of the reinforcement 2 is completely covered by the additional insulating material I in so far as construction of the slab 7 made of concrete is not envisaged.
- a peculiar characteristic of the invention lies in the fact that provision of said lightening inserts or cores 2a of the floor in the reinforcements 2 enables use of painted or in any case anti-corrosion-treated reinforcements, without said treatment or painting being damaged during assembly, thus obtaining that said reinforcements 2 are protected from corrosion even though they are not completely embedded in the concrete.
- connection between the metal reinforcements 2 and the concrete slab 7, which has a load-distribution reinforcement, such as for example the electrowelded mesh and/or the intermediate supporting transverse re-rods 8, is obtained by means of the concrete casting for the longitudinal ribbings 6 and transverse ribbings provided in the shaped element made of (insulating) expanded material 1.
- the hybrid structural element according to the present invention functions to all effects as formwork and requires the same type of propping necessary for construction of a traditional floor to be laid in situ with the possibility of use for bidirectional floors.
- the floor to be laid envisages that the reinforcements are not completely embedded in the concrete ( Figure 1 ), and hence the lightening cores 2a are provided within the lattice reinforcements 2, it is sufficient to use props in the middle in order to be able to carry out the operations of casting.
- a further possible application envisages pre-casting, in the factory, a part of the concrete just to cover a part of the metal lattices 2, leaving exposed the top area of the lattices themselves, which is located within the groove 6 for creating the longitudinal ribbings between the bottom part of the slab 7 and the top part of the insulating material 1.
- the reinforcements are completely embedded in the concrete, and the floor can be mounted in situ by casting just the concrete slab 7, which binds to the rest precisely thanks to the reinforcements.
- the typical width of the standard element is preferably 120 cm (like the majority of prefabricated floors). It is, however, possible to envisage any size between 15 and 240 cm.
- the shaped slots or grooves SL provided in the standard plates of expanded material are set at regular intervals in a number preferably ranging from one to seven.
- the height of the standard element is 16 cm, 20 cm, 25 cm, 30 cm, 35 cm, to be added to which is the thickness of the completing concrete slab 7.
- the standard structural element obtained according to the present invention may be used, for example, for:
