(57) This invention is based on an system for manufacturing undertile roofs or ventilated walls. It is made of a metal frame consisting of metal section bars and special pieces jointly fixed to a sheet made from an insulating material (extruded foam polystyrene, sintered foam polystyrene, foam polyurethane, rock wool, etc.) made supporting by the insertion of metal section bars on its lower surface.




Description

Technical field



[0001] This invention is based on an innovative system for manufacturing undertile roofs or ventilated walls. It is made of a metal frame consisting of metal section bars and special pieces jointly fixed to a sheet made from an insulating material (extruded foam polystyrene, sintered foam polystyrene, foam polyurethane, rock wool, etc.) made supporting by the insertion of metal section bars on its lower surface.

State of technique



[0002] Today systems with pre-fabricated panels for the manufacturing of undertile ventilated roofs do not exist. The existing panels are not modular and do not allow the universal application of tiles and pantiles of any size. They are also not provided with zinc plated battens and are not self-protected with a transpirating and water resistant membrane. They cannot always support the load of snow and men. The existing prefabricated undertile systems are only microventilated and therefore they are not conforming with the rule on ventilated roofs, which requires a minimum thickness of 5 cm of the air blade. As regards ventilated walls, the applicant knows that they are manufactured by first applying a metal frame and then, within the frame, the insulating material with big costs and long working times.

[0003] Purpose and advantages of this invention

[0004] The purpose of this invention is that of developing a preassembled panel system which allows to obtain a supporting covering of a ventilated roof.

[0005] Another purpose is that of providing a modular panel system allowing the application of any kind of tile or pantile.

[0006] A further purpose of this invention is that of obtaining a panel with its own supporting structure which by its application on the wall, allows to have a ventilated wall with an external insulation.

[0007] These and other advantages will emerge from the following description of the system.

[0008] Description of drawings and procedure for implementing this invention

[0009] The idea of this system is that of manufacturing a composed metal frame being supporting thanks to metal section bars and pieces jointly fixed to an insulating material sheet (extruded foam polystyrene, sinterized polystyrene foam, polyurethane foam, rock wool, etc.) provided with metal section bars on its lower surface. This idea will be better understood if you refer to the enclosed figures, where it is reported in a version which is only as an example.

[0010] Fig.1 is an exploded view of the system, it well shows the components of the system itself.

[0011] Fig.2 is an exploded view in which the mounting of the system components is shown.

[0012] Fig.3 shows the frame with some tiles and pantiles applied on it.

[0013] Fig.4 shows a kind of panel for wall linings to be wall applied.

[0014] Fig. 5 shows the composition of more panels for walls.

[0015] With reference to the figures, the system avails itself of an insulating material sheet (1), to the lower surface side of it metal omega section bars (2) are embedded and transversally applied.

[0016] On the upper surface of the above said sheet spaced and parallel pitch U bars (3) with turned edges (4) are applied.

[0017] An element (5) with a quadrangular base having holes in the middle and end specially mushroom shaped wings, with opposed and turned faces, two of them upwards (6) and the other two ones downwards (7), functions as junction element between the section bar (3) and the section bar (8) orthogonally superimposed over the former, this one being a U bar too and having turned edges.

[0018] The junction element (5) is provided with an end wing (6) or (7), two notchings (11). The wings (7) are shorter than the wings (6).

[0019] Being the components so described and illustrated, it is evident that after having fixed the section bars (3) to the sheet (11), the junction elements (5) can be applied to the above said section bars, by inserting the wings (7) within the U bar by a light snap pressure, then they can be suitably spaced from each other.

[0020] Then, on the wings (6) the section bars (7) can be snap inserted and fixed by a bolt.

[0021] The above described and illustrated mounting represents a whole module which can be used as under roof element on which tiles (9) and pantiles (10) can be applied and fixed.

[0022] The mounting described and illustrated above represents a module which can be used as a ventilated wall element with external insulation. In this case the panel is joined to the wall surface by a mechanic fixing with screws inserted in the special holes of the rail structurally fixing the panel, provided with ledges on four sides, allowing a rapid fixing to other panels, during mounting.

[0023] The above said panels can support different kinds of lining: wood, aluminium, polycarbonate, etc.

[0024] The junction elements (5) can be more or less high to determine the existing space between the section bar (3) and the section bar (8), according to the desired ventilation corridor. They are made, as well as U and omega shaped section bars and the fixing screws from 6/10 zinc plated steel.

[0025] The advantages of the above described system are:

a supporting panel reinforced by lower metal section bars, linked to metal upper section bars, is obtained;

it becomes modular in order to allow the wall application with any kind of lining and

the roof application with any kind of tile or pantile, since the pitch is decided at the moment of installation and it does not need any modification or special equipment;

it guarantees a perfect ventilation, ventilation channels have got a minimum light of 5 cm., as it is provided by the regulations in force;

reduction of stock amounts for retailers, since this product is suitable for any kind of existing tiles;

an only system for both thermal and acoustic insulation is obtained;

the laying of the covering allows to operate with the utmost safety, because all panels are made of a supporting kind by the two section bars inserted on the side of panels to be laid on the underlying structure.



[0026] The ventilated walls manufactured according to the present invention, can reduce heat in the building during the hot season, thanks to the partial reflection of solar radiation from the lining, the air space ventilation and the insulating material application, thus obtaining a big reduction of air conditioning costs.

[0027] Viceversa, in the winter season, the ventilated faces keep the heat fostering a big reduction of heating costs.

[0028] The "chimney" effect gives place to a natural ventilation, from which the term ventilated face is born, guaranteeing big benefits due to the elimination of heat and moisture and a high inhabiting comfort.

[0029] Moreover ventilated walls easily cause the reflection of external noises thanks to their composition made from facing layers, air spaces and insulating material which facilitate acoustic absorption.

[0030] Formal and structural changes, within the same invention idea, which is defined by the following claims, can be made to the above described solution.
