Definitions

  • the present invention relates to a roof, in particular for houses.
  • the present invention is suitable for use in the building sector and, in particular, addresses to any type of house or similar building construction.
  • Every building construction such as houses, condominiums, sheds and the like, is provided with a roof at the top which is able to shelter and protect the inside volumes or rooms from atmospheric agents.
  • the roof must be able both to protect the inside volumes from rain and snow falls and to thermally isolate the same during the different seasons of the year.
  • a roof comprises a load-bearing structure, such as roof frames made of structural wood, trusses, steel section bars, prestressed reinforced concrete panels or reinforced concrete floors, fastened to the upper portion of the load-bearing walls of the corresponding building structure.
  • a load-bearing structure such as roof frames made of structural wood, trusses, steel section bars, prestressed reinforced concrete panels or reinforced concrete floors, fastened to the upper portion of the load-bearing walls of the corresponding building structure.
  • Usually associated with the load-bearing structure is one or more layers of insulation material adapted to provide a suitable heat insulation relative to the external environment.
  • the load-bearing structure can ultimately be provided with an inner sheathing or a garret mainly used in order to increase the roof heat insulation.
  • roofs in houses have an inclined geometric shape resulting from one or more inclined flat faces, termed pitches or slopes.
  • pitches or slopes usually, sloping roofs have at least one ridge defined by intersection of the planes of two slopes and at least one eaves edge corresponding to the lower end portion of each slope.
  • the Applicant has found that known roofs promote accumulation of heat inside the building structure during the hot seasons and do not conveniently insulate the inside volumes during the cold seasons, which has a great impact on the use of the heating system and the related costs.
  • the present invention aims at solving the problems found in the known art.
  • a roof in particular for houses, in accordance with the present invention has been generally identified with 1.
  • a building structure 2 is diagrammatically shown, such as a house, a condominium or a shed, provided with a roof 11 capable of protecting one or more inside volumes or rooms 3 from atmospheric agents, such as rain or snow falls, wind, humidity.
  • Roof 1 comprises at least one inclined sector 4, hereinafter termed pitch, lying in an inclined plane relative to a horizontal reference plane "X".
  • roof 1 as shown in the attached figure, is provided with two pitches 4 each extending from a respective side wall 5 of the building structure 2 and converging towards each other to form a ridge 6 defining the top of the structure itself.
  • each pitch 4 defines a corresponding eaves line 7 at which a gutter 8 is located.
  • roof 1 is provided with at least one covering mantle preferably consisting of a plurality of roofing tiles 9a made of bricks or cement, facing outwards and designed to protect the inside volumes 3 from several atmospheric agents.
  • the covering mantle 9 which is considered as the preferred solution, does not at all limit the present invention.
  • roof 1 can be also made using other types of discontinuous coverings, such as slabs of asbestos cement, stone, plastic materials, as well as bituminous roofing tiles, insulating metal panels and/or fretted sheet metal of zinc plated steel and so on.
  • the roof can also consist of continuous coverings, made impermeable by a cold or hot treatment, of synthetic membranes or bituminous membranes.
  • roof 1 comprises at least one insulating layer 10, interposed between the covering mantle 9 and the inside volumes 3 to thermally insulate the latter from the external environment.
  • the insulating layer 10 is made up of a plurality of insulated panels 10a suitably provided with corresponding upper supports 10b designed to support the roofing tiles 9a of the covering mantle 9 resting thereon.
  • the insulating layer 10 is supported by at least one load-bearing structure 11, preferably a lattice-like structure, under which at least one lower sheathing 12 facing away from the covering mantle 9 is disposed.
  • the lower sheathing 12 is defined, at the inside volumes 3, by at least one false ceiling or a garret 12a propped up by a series of supports 12b which are directly fastened to the load-bearing structure 11.
  • roof 1 is provided, at least at each pitch 4, with at least one air space 13.
  • the air space 13 is preferably in fluid communication with an inlet opening 14 formed through the lower sheathing 12 and a vent opening 15 formed at least through the covering mantle 9.
  • the vent opening 15 is formed through the covering mantle 9 at the top of pitches 4.
  • the vent opening 15 is positioned close to ridge 6.
  • the vent opening 15 can be driven to a closed or open condition by an occlusion mechanism 16 operatively associated with at least one vent hole 17 provided through the insulating layer 10 in register with a position corresponding to the vent opening 15.
  • the occlusion mechanism 16 preferably comprises an insulated closing element 16a, manually operable through one or more suitable mechanisms, and/or electrically operable by means of suitable electric actuators.
  • the air space 13 is interposed between the lower sheathing 12 and the covering mantle 9.
  • the air space 13 is interposed between the lower sheathing 12 and the insulating layer 10.
  • the air space 13 houses the lattice-like load-bearing structure 11 which is suitably fastened to the upper portion of the side walls 5.
  • the inlet opening 14 is formed through the lower sheathing 12 close to the corresponding side wall 5 of the building structure 2.
  • the inlet opening 14 is advantageously positioned within the building structure 2, and is in fluid communication with the inside volume 3.
  • the vent opening 15 when the vent opening 15 is in the open condition, the air present within the air space 13, heated by sun radiation, has a tendency to get out of the vent opening 15.
  • the rising air due to the stack effect, attracts the air present in the inside volume 3 in which there is a continuous state of recirculation of air, which will cause a constant cooling ventilation.
  • the vent opening 15 when the vent opening 15 is suitably occluded, by operating the corresponding occlusion mechanism 16, the air present inside the air space 13 defines a further insulating layer greatly increasing the heat insulation carried out by the insulating layer 10.
  • the inlet opening 14 comprises at least one slit extending close to the respective side wall 5 on which the lower portion of the corresponding pitch 4 lies, in such a manner that the whole inside volume 3 is suitably in fluid communication with the air space 13.
  • the inlet opening 14 or slit extends along the whole extension of the corresponding side wall 5.
  • the inlet opening 14 has a width, measurable from the corresponding side wall 5 to the ridge 6, included between 5 mm and 25 mm, preferably between 10 mm and 20 mm, more preferably equal to 15 mm.
  • the inlet opening 14 is provided with at least one grid (not shown) preferably a microperforated section member enabling passage of air alone between the inner volume 3 and the air space.
  • the inlet opening 14 can be provided with a closing device (not shown) operable between an open condition at which the air is free to flow through the inlet opening 14, and a closed condition at which entry of air inside the air space 13 is not allowed.
  • a closing device (not shown) operable between an open condition at which the air is free to flow through the inlet opening 14, and a closed condition at which entry of air inside the air space 13 is not allowed.
  • the air space 13 can be provided with one or more obstruction devices 19 operable between an open condition, at which the air is able to circulate within the air space 13, and an obstructed condition, at which the air space 13 is divided into at least two compartments 13a terminating at the inlet opening 14 and at the vent opening 15, respectively.
  • the obstruction device 19 comprises at least one insulated closing element 19a operatively disposed within the air space 13 between the inlet opening 14 and the vent opening 15.
  • At least one air intake 20 can be formed through one of the side walls 5 of the inside volume 3 to bring the latter into fluid communication with the external environment. In this way, during the upward flow of the heated air present in the air space 13, the fresh air from the outside passes through the air intake 20 and flows towards the air space 13 and the vent opening 15.
  • the air intake 20 is provided with suitable grids or insulating nets 20a.
  • the above mentioned cooling flow and the change-of-air flow can be obtained by operating a fan 16b operatively associated with the vent opening 15, preferably inside the vent hole 17. In this manner, the air present in the air space 13 is ejected through the vent opening 15 and new air is brought back into the inside volume 3 through the air intake 20.
  • Fan 16b can be activated both by a direct request, through use of a suitable activation switch, and automatically, through a suitable programmable electronic timer.
  • At least one heating device 21 can be also operatively associated with the air intake 20 so as to act, after activation, on the air passing through from the outside to the inside.
  • the heating device 21, consisting for example of an electric resistor and/or a radiator operating close to the air intake 20, is designed to be activated during the cold seasons, when it is necessary to evacuate the moisture-charged hot air present at the inside of the air space 13 and replace it with less moist fresh air from the outside.
  • the present invention solves the problems found in the known art and achieves important advantages.
  • the roof according to the present invention allows a constant natural ventilation of the inside volumes of the house with which it is associated during the hot seasons and greatly reduces the loss of heat of said house during the cold seasons.
  • the roof of the invention through the stack effect is able to generate an air displacement from the inside volumes of the house to the external environment, as the air rises along the air spaces formed inside the pitches. Said air displacement along the air spaces inhibits accumulation of heat within the roof, so that the surface and interstitial condensate is eliminated and formation of moulds is avoided, which will make the air more wholesome and free from humidity.
  • vent opening in the vicinity of the ridge allows the moisture-charged hot air to exit and to be replaced by drier and more wholesome air that therefore can be heated more easily.
