Abstract
Abstract A prefabricated concrete panel for building floors in civil or industrial structures, comprising a concrete body with a reinforcement provided with portions which protrude from one of the larger faces of the body of the panel which constitutes extrados of a floor and are designed to be embedded in the casting of the topping of the floor. At least one first shaped sheet is provided inside the body of the panel, is made of thermally insulating material, is interposed between the two larger faces of the panel body and forms, between the two larger faces of the panel body, a ventilation chamber which is composed of a plurality of mutually connected cells.

A prefabricated concrete panel for building floors in civil or industrial structures, comprising a concrete body with a reinforcement provided with portions which protrude from one of two larger faces of the body of the panel which constitutes extrados of a floor and are designed to be embedded in a casting of a topping of the floor, at least one first contoured sheet being provided inside the body of the panel, said sheet being made of thermally insulating material, being interposed between the two larger faces of the panel body and forming, between said two larger faces of the panel body, a ventilation chamber which is composed of a plurality mutually connected cells.
Claim 2
Dependent Claim
113 words
A prefabricated concrete panel for building floors in civil or industrial structures, comprising a concrete body with a reinforcement provided with portions which protrude from one of two larger faces of the body of the panel which constitutes extrados of a floor and are designed to be embedded in a casting of a topping of the floor, at least one first contoured sheet being provided inside the body of the panel, said sheet being made of thermally insulating material, being interposed between the two larger faces of the panel body and forming, between said two larger faces of the panel body, a ventilation chamber which is composed of a plurality mutually connected cells.
Claim 3
Dependent Claim
43 words
The panel according to claim 1 , wherein said reinforcement comprises longitudinal profiles which are arranged on a plane which is substantially parallel to the two larger faces of the panel body and are orientated parallel to the larger sides of the panel.
Claim 4
Dependent Claim
31 words
The panel according to claim 2 , wherein said reinforcement has a frame-like structure which is composed of said longitudinal profiles and of transverse profiles which mutually connect said longitudinal profiles.
Claim 5
Dependent Claim
81 words
The panel according to claim 2 , wherein said profiles have a substantially C-shaped or Σ-shaped transverse cross-section with two end wings which are arranged on planes which are parallel to each other and to the larger faces of the panel, said end wings being connected by an intermediate wing; one of said two end wings and a portion of said intermediate wing protruding from one of the larger faces of the panel body that constitutes the extrados of the floor.
Claim 6
Dependent Claim
55 words
The panel according to claim 1 , comprising a second sheet which is embedded in the concrete and faces said first sheet, said first and second sheets being arranged on planes which are parallel to planes of arrangement of the two larger faces of the panel body, said sheets delimiting said ventilation chamber between them.
Claim 7
Dependent Claim
80 words
The panel according to claim 5 , wherein said first sheet is shaped so as to form mutually laterally adjacent cups which form concave recesses on the face of said first sheet that faces said second sheet, the side of said recesses that is directed toward said second sheet being closed by said second sheet; said recesses constituting said cells and being connected to each other by means of connecting ducts which have smaller air passage sections than said recesses.
Claim 8
Dependent Claim
29 words
The panel according to claim 6 , wherein said recesses are mutually connected through passages formed in the edges of said cups that are directed toward said second sheet.
Claim 9
Dependent Claim
32 words
The panel according to claim 6 , wherein said recesses are connected to at least one ventilation duct which has an outlet onto an outer side of the body of the panel.
Claim 10
Dependent Claim
23 words
The panel according to claim 8 , wherein on the outlet of said at least one ventilation duct there is a protective grille.
Claim 11
Dependent Claim
19 words

Claim 12
Dependent Claim
53 words
The panel according to claim 8 , wherein the outlets of the ventilation ducts can be connected, by means of tubes, to the outlets of the ventilation ducts of contiguous panels in order to connect to each other, and to the outside, the ventilation chambers of the various panels that compose the floor.
Claim 13
Dependent Claim
55 words
The panel according to claim 6 , wherein said cups are delimited, on the face of said first sheet that lies opposite said second sheet, by grooves which are recessed with respect to the back of said cups which protrudes from said face of the first sheet that is directed away from said second sheet.
Claim 14
Dependent Claim
34 words
The panel according to claim 12 , wherein on the back of said cups there are protruding ribs for supporting reinforcement bars, or a net-like reinforcement, embedded in the concrete body of the panel.
Claim 15
Dependent Claim
18 words
The panel according to claim 13 , wherein said protruding ribs also affect said grooves between said cups.
Claim 16
Dependent Claim
22 words
The panel according to claim 14 , wherein said protruding ribs run diagonally with respect to the larger faces of the panel.
Claim 17
Dependent Claim
33 words
The panel according to claim 14 , wherein said cups have a substantially rectangular base, said protruding ribs being arranged along a diagonal of the rectangular shape of the back of said cups.
Claim 18
Dependent Claim
14 words
