Patent application for industrial invention entitled:

â € œMODULE FOR COAT AND COATâ €

DESCRIPTION FIELD OF INVENTION

The present invention relates to an external insulation module and to an external insulation module that uses it.

Traditionally, the term â € œcoatsâ € means that structure that covers the vertical surface of a building, and which is suitable both to protect the external walls of the building from atmospheric agents and to improve their thermal performance (in particular the 'thermal insulation).

The present invention finds particularly advantageous application in â € œventilated overcoatsâ €, that is, â € œcoatsâ € in which between the external surface of the external massive wall of the building (not thermally insulated) and the internal surface of the external insulation there is a cavity in which air can circulate.

STATE OF THE TECHNIQUE

The “ventilated coat” is a well-known solution that provides excellent results even if it is not very common.

This solution is based not only on the fact that air is an excellent thermal insulator, but also on the fact that an air flow can be used to change the temperature of an object that comes into contact with this flow (for example lapped).

Some practical implementations of the â € œventilated coatâ € (known from the patent literature) provide that the cavity can be opened and closed; when the cavity is open the air can enter and exit the cavity while when the cavity is closed the air remains in the cavity.

SUMMARY

The known solutions of â € œventilated hoodâ € do not pay particular attention to the closing and opening system for the flow of air into and from the cavity.

In particular, the Inventors realized that no attention was paid to the airtightness, thermal insulation, operation and industrial implementation of this system as well as its implementation (generally by unskilled personnel ).

According to a first example of embodiment, the present invention is applied in the terminal parts (lower and upper) of the external building envelope of the systems known as "ventilated coats", as shown in Fig.4. known technique (see Fig. 1), assumes the presence of a massive wall 1, for example a wall (existing or newly built) adjacent to an inhabited space, on which panels 2 associated with spacer heels 14 are applied; purely indicative title, please note that the size of the panel is 60 cm in height, for 120 cm in width and for 8 cm in thickness and the dimension of the heels is 8 cm, for 8 cm and for 8 cm in thickness .

These heels 14 form a gap 3 between the wall 1 and the panels 2. The heels 14 are preferably of thermal insulating material and are placed on the panels 2 by means of adhesive mortar; alternatively, the panel and the heels could be made in a single preformed piece. Subsequently the panels 2 are mounted on the wall 1 with suitable mechanical fasteners (for example mushroom dowels 20), proceeding in horizontal rows from bottom to top. Panels 2 are generally equipped with a compressive strength of at least 2.5kg / m2 and with adequate fire resistance and non-flammable. An external finish 23 is then provided, which can be of various different types.

Differently from the known technique, according to the present invention, the modules for insulation of the first and last row are constituted by particular modules (see in particular Fig.4) which are in turn the object of the present invention.

Before installing the panels 4, a starting profile 6 (placed horizontally) equipped with a drip 22, for example in perforated light alloy, is laid with the function of starting alignment, protection and containment of the superior insulation. An element 5 (placed horizontally) is mounted adjacent to this profile 6 with the function of closing the interspace 3 at the bottom and at the top and, in correspondence with the panels 4, forming a support plate for the cap 7 in the open position.

These elements 5 and 6 are positioned in the first phase of installation along the entire lower and upper perimeter of the surface where the ventilated coat will be applied. Elements similar to elements 5, but placed vertically instead of horizontally, will serve as a possible lateral closure of the cavity 3.

Subsequently, the insulation modules are laid, which are advantageously pre-assembled (preferably totally pre-assembled), which are made up of the following elements (see Fig. 2 and Fig. 3):

a square 4 of thermal insulating material with spacer heels 14 and 15 suitably spaced from the outer edge to allow the passage of electrical cables; they are distinguished in cubic-shaped heels 14 and elongated parallelepiped-shaped heels 15; a cap 7 arranged horizontally of thermal insulating material, shaped so as to obtain a watertight seal; it has a parallelepiped shape and can have a rectangular or trapezoidal section (in Fig. 3 the cap has a rectangular section; in Fig. 4 and Fig. 5 the two caps have a trapezoidal section; in Fig. 6 a cap has a rectangular section and a cap has trapezoidal section); the heels 15 are also used to close the interspace 3 laterally when the cap 7 is in the closed condition;

an electrically controlled actuation system 19 consisting of a gearmotor 9, connected by means of a rod 8 to two transmissions 10 which control two rods 11 which lengthen / shorten thanks to a screw-sleeve coupling system; the rods 11 impart to the cap 7 a translation upwards (when closing the interspace 3) or downwards (when opening the interspace 3); the rotation movement of the rod 8 is transmitted by means of a rod 27 to a slider 28 in order to be able to block the movement of the system once the final opening or closing position of the cap 7 has been reached; in particular, in order to block the system, the slider 28 abuts on two limit switches 29; the electric power supply cables of the actuation system have a male-female terminal for easy connection on site; The insertion of a relay is foreseen to guarantee the continuity of the line in case of actuator malfunction; for this eventuality the other modules equipped with an actuation system will continue to function making the defective panel easy to identify and repair;

a fixed vertical plinth 12 of thermal insulating material to avoid thermal bridges, which is placed between two heels 15;

two sealing gaskets 13 to avoid air infiltrations, one placed in correspondence with the cap 7 and one placed in correspondence with the plinth 12.

Fig.3B1 shows the insulation module with the relative valve in the open position: the cap 7 is not in contact with the extreme area (lower in the case of Fig. 3) of the edge of the panel 4 and the two gaskets 13 do not estate. Fig.3B2 shows the insulation module with the relative valve in the closed position: the cap 7 is in contact with the extreme area (lower in the case of Fig. 3) of the edge of the panel 4 and the two gaskets 13 make a seal.

An anti-insect grid 21 and a drip tray 22 will be inserted in correspondence with the lower and upper openings of the ventilation channel 3.

It also provides for the installation of a metal cover 25 with a drip in the upper part of the wall to avoid infiltration of rainwater. Advantageously, these external insulation modules according to the present invention are suitable for industrial production and are supplied on site already complete, i.e. equipped with caps, thermal bridge correction base, gaskets and handling system (rods, actuator, transmissions and cables electrical).

The external insulation modules are marked and placed on the wall preferably without adhesives (exclusively with mechanical fixing similar to that used for traditional insulation modules) to facilitate any subsequent maintenance.

The electrical cables of the external insulation modules are connected during the installation phase thanks to the provision of suitable male-female terminals. The passage of the cables involves both the modules according to the invention and the traditional modules adjacent to them. The cable will connect the gearmotors 9 to a power supply connected to a panel with warning lights for any faults. The panels will be connected to an on / off pushbutton panel to activate the movement system in the summer or winter phase. Said movement system can also be controlled automatically by air temperature detection probes.

According to a second example of embodiment, these innovative modules find application in the construction of roofs, with an insulation system of the roof slab of the same type already described for the walls. In fact, the optimization of the flat or inclined roof slab assumes particular importance in temperate climates. In the summer, when solar radiation hits the building with a high angle of incidence, the roof slab is subjected to a considerable thermal load and creates overheated, sometimes unlivable attic rooms.

As in the case of the first example, the combination of known modules and innovative modules allows the creation of a ventilation layer 3 between the insulation and the massive internal floor.

Also for the case of roofs, the proposed system can be adopted for newly built casings or for the â € œrefittingâ € of existing buildings, both for flat and sloping roofs.

The system can be applied on traditional or "inverted roof" roofs, adopting in the first case smooth insulating panels (not diamond-shaped or corrugated) to allow the application of adhesive bituminous membranes. In Fig. 4 and Fig. 5, by way of example, the application of the proposed system on a flat roof with an inverted roof is shown. In this case, the ventilation chamber 3 is positioned above the screed of the slopes 16, where the waterproofing layer 17 rests for the outflow of rainwater.

There are two possibilities:

the ventilation gap 3 of the roof and the wall, both with the proposed system, are connected and use the same openings (and caps 7) for the outflow of hot air (see Fig. 4 above); in this case, the roof is not provided with modules according to the present invention (but uses that of the wall) and the connection between the two air chambers 3 (horizontal and vertical) takes place through through openings 18 made in the upper cornice;

the roof and the wall are independent of each other, with differentiated openings (see Fig. 5); in this case, the wall and roof modules according to the present invention are distinct and differentiated.

In both cases, all the top extrados finishing layers are laid over the thermal insulation (for flat roofs it is also possible to apply packages of the so-called `` inverted roof '' material as a single layer of non-woven fabric 26 and a layer of gravel 24).

In the case of pitched roofs (see Fig. 6), the first and last row of thermal insulation modules (adjacent respectively to the gutter and the ridge of the roof) are replaced by modules according to the present invention, provided with caps closing / opening similar to those described above.

In the exemplary case presented in Fig.6, the panels 2 and 4 of the modules are smooth (not diamond-shaped or corrugated) to allow the upper application of waterproofing membranes 17; on the underside of the insulation, any vapor barriers must be installed 30.

In accordance with the present invention, the winter thermal insulation guaranteed by the optimized ventilated coat is more effective than in the conventional technique. The ventilation control caps in insulating material, equipped with sealing gaskets, prevent the infiltration of cold air and the dispersion of heat because the sealed air chamber thus created helps to reduce the thermal dispersion of the wall and therefore energy saving and comfort are guaranteed.

The use of this coat also for the roofs, with the same details studied for the wall, allows to considerably improve the performance of the roofs in summer and winter, both in terms of comfort and energy saving.

The module according to the invention is of the industrialized type. In fact, the handling system complete with rods, actuator, returns and electric cables is inserted into the module during the production phase. The spacer heels are also glued in the production phase or are already preformed. The module according to the invention arrives on site already assembled. All the optimized ventilated insulation system (normal and special modules) can be industrially produced and installed with the same operations required by a simple external insulation system. The proposed module therefore makes it possible to create ventilated coats and ventilated roofs with considerable cost savings and ease of assembly.

The present invention has been described according to preferred embodiments but equivalent variants can be conceived without departing from the scope of the claims annexed hereto.
