Description

INFILL PANEL FOR BUILDING SPACES AND RELATIVE PREPARATION METHOD
Technical Field
The present invention relates to an infill panel for building spaces and relative preparation method.
Background Art
Building technology of the conventional type today almost constantly proposes the building of new homes with the use of materials of synthesis, of more or less new concept which, in general, given a gradual improvement of the functional efficiency characteristics during operation, often frequently also imply, at the same time, a growing need for energy for the production of the materials themselves.
In terms of global energy assessment, this approach prevents to a large extent a part of the energy benefits deriving from the obtaining of buildings which, in general, are less energy dispersing compared to buildings of the past.
Furthermore, in buildings integrating the above-mentioned materials of synthesis, the infill walls (irrespective of their type: vertical, for perimeter or inner walls; or horizontal, for floors and roofs) are not as heavy as in the past. Their lower unitary weight results in lower thermal, inertia, and consequently, part of the energy saving benefits, achieved from winter heating and tied to the lower heat conduction of the infill wall, are, during summer cooling, lost due to the lesser capacity of the masonry structure to contrast the thermal peaks occurring during the course of the day.
Also negatively affecting the global energy balance is the problem of the demolition of existing building structures, in relation to which energy requirements are fairly high: not only to demolish old buildings, but also to remove the waste materials from the restructuring and rebuilding worksites.
This problem appears all the more serious if account is taken of the fact that the deposit sites of such materials are often rather far away from the production site of the demolition material, and this implies long and costly transport times which once again negatively affect overall costs and energy balance.
Description of the Invention The object of the present invention is to overcome such problems by providing an infill panel able to allow erecting buildings with low energy consumption and low environmental impact, with the possible recovery, conditioning and reuse, including on site, of the previous demolition waste materials.
According to the invention, such object is achieved by an infill panel comprising the technical characteristics indicated in one or more of the attached claims from 1 to 8. A further part of the invention is also a panel preparation method the technical characteristics of which are expounded in one of the attached claims from 9 to 20.
Brief Description of the Drawings
The technical characteristics of the invention, according to the above mentioned objects, are clearly found in the claims below, and the advantages of same will become more evident in the following detailed description referring to the enclosed drawings, which represent just an example but not limited embodiment:
Figure 1 is a schematic section of a building integrating a panel according to the invention;
Figure 2 is a section view of a building detail of a joint between two adjacent filling panels;
Figure 3 is a schematic representation of a succession of stages through which a panel manufacturing process is obtained;
Figure 4 is a schematic representation of a succession of stages through which another panel manufacturing process is obtained.
Embodiments of the Invention
With reference to figure 1 in the enclosed drawings, globally indicated by 1 is an infill panel of a building space generally indicated by 2.
The panel 1 essentially comprises a mould 3 having a container body 4, substantially parallelepiped, having walls 5 in wood material defining a containment compartment 6 inside the panel 1 , such compartment 6 preferably having a honeycomb structure defined by a number of compartments 25, better seen in figure 3. The container body 4 has, more in particular, a base 26 widened with respect to the overall dimensions of the compartment 6. The mould 3 also has a lid 7, this too made of wood material, associable with the container body 4, on the opposite side to the base 26. The panel 1 includes a first loose aggregate material 8, in calibrated size, which is housed in the containment compartment 6 of the mould 3 and which is confined and stably retained there between the container body 4 and the lid 7 by means of the interconnection of the lid 7 to the container body 4 itself.
The first aggregate mineral material 8 can include sand or gravel or crumbled stone. Or it can equally advantageously include broken up cotto or brick; or also the rubble of demolished buildings or previous constructions which, e.g., have been restructured or completely rebuild after being knocked down.
The first mineral material 8 is crumbled into tiny pieces of as uniform a size as possible, in the range of around 3 or 4 mm.
By effect of the structuring of the panel 1 described above and due to the effect of the high thermal insulating characteristics of the materials which altogether make up the panel 1 , the total thermal transmittance of the panel 1 is very low and such as to satisfy the most restrictive criteria established by the current regulations concerning energy reduction in the building trade.
In the event of further improvement being sought in terms of thermal insulation, the thermal transmittance can be corrected so as to further reduce the heat conduction characteristics of the panel 1. In this respect, the first aggregate material 8 can be advantageously added and mixed in solid state with a second aggregate material 9, having a transmittance lower than that of the first material 8.
By adopting an adequate mix ratio between the masses of the two aggregate materials 8 and 9, the thermal transmittance of the two mixed materials as a whole can be kept below a preset threshold value and such transmittance can be modulated according to need.
An aggregate material particularly advantageous to make such corrections can be identified, e.g., in blast furnace slag which, once it has been broken up and crumbled so it is of a size comparable to that of the first aggregate mineral material 8, can be mixed together with the latter.
As can be seen from the figure 1 , the panel 1 can be advantageously integrated towards the outside of the building construction and superimposed on its base 26 associated with the outer facade of the building, with a first covering layer 10 of thermal insulating material. In the event of wanting to make a passive external ventilation air space 12, a second covering layer 1 1 can be superimposed on the first covering layer 10 and retained at a distance from it so as to define the air space 12 between the two layers 10 and 1 1.
Towards the inside of the habitation, the panel 1 can advantageously integrate the plasterboard covering panels 27 counter- facing its lid 7.
The same structuring to that described by way of example for the vertical walls of the building structure can also be attributed to the horizontal structures made to form the floors or the roof of the habitation. In this respect, the figure 2 shows a schematic example of such types of walls, from which it can be seen that, irrespective of details known to technicians in the sector and pertinent to the embodiment of the joints between two adjacent panels, to make horizontal structures, panels 1 can be used consisting of a mould 3 in wood material filled with aggregate material, enclosed and confined in the inner cavity 6 of the panel I .
The panel 1 can be installed in the wall structure with the mould 3 associated with the opening to be closed and, as shown in figure 1 , with the container body 4 associated with the opening of the building construction and placed with the base 26 up against the outer facade of the construction.
The introduction of the aggregate material 8 into the compartment 6 of the panel 1 can be performed directly during the course of work, e.g., by insufflating the aggregate material 8 and if necessary adding a binder directly and inside the compartment 6 passing through the temporary openings, which can then be definitively closed after filling.
The method of preparation of the panels 1 can however have further possible execution variations.
One of these is shown in figure 3, wherein are schematically described the operating steps of a preparation method of the infill panels 1 , to be preferably but not exclusively implemented inside a workshop separated from the building site for which the panels 1 in conformity with the invention, are intended. More in particular, in the succession of the steps of figure 3, by A) is indicated the assembly of the various wooden parts which go to make up the container body 4 of the mould 3, such assembly being made on a bench 14.
In the subsequent step B) the container body 4 is filled in the various compartments 25 of its internal compartment 6 with the aggregate material 8 or with a mix of the first aggregate material 8 and the second aggregate material 9. The aggregate material 8 can be conceived as being supplied by a container bin which is not shown. If the bench 14, or one of its operating sections, is a vibrating bench, the filling of the container body 4 can be done in a uniform and complete way, with total settling of the aggregate material 8: this permits having a panel 1 with thermal performance technically uniform throughout its mass. In the step C), the lid 7 is fitted to the container body 4 which seals and confines the aggregate filling material 8 inside the container body 4.
In the subsequent step D), beside fitting to the panel 1 further covering layers such as, e.g., one or more vapour barriers suitable for preventing the absorption of humidity by the aggregate material 8 during installation, and/or further layers 10 and/or 1 1 of insulation, or covering panels 27 in plasterboard, the panel 1 receives the means 13 (shown symbolically) for gripping, lifting and mechanized transport of the panels 1.
In the subsequent step G), the panels 1 which have reached the worksite, are assembled in the recipient building construction according to the assembly diagram of figure 1.
Another alternative preparation method, particularly advantageous in case of the reuse of the waste material of a previous demolition, is schematized in figure 4. In this figure, it can be seen that in a step A) the waste material, previously broken up, sifted and made uniform in size, is accumulated in a large container 29.
More in detail, following the breaking up of the waste material, the first broken up aggregate material 8 appears in the form of an agglomerate of different materials (cotto, brick, various metals, and others still) and a step can be envisaged wherein the different materials present in the first broken up aggregate material 8 are separated. Before being introduced inside the mould 3 (Step C), the waste material present in the large container 29 undergoes a preparation process involving a step of drying the humidity contained in it.
Such drying step is obtained inside a rotary container 16 by means of a heating unit 17 associated with said container 16.
In conformity with a first embodiment, the heating unit 17 can be implemented by a thennal lance 18 associated with the rotary container 16. A different embodiment of the heating unit 17 can also be advantageously made by means of the use of a microwave heater associated with a loading pipe 30 which, from the large container 29, conveys the aggregate material 8 into the compartment 6 inside the mould 3 arranged above a roller table 31.
The invention as described and illustrated fully achieves the objects and is qualified by numerous advantageous aspects. It does in fact permit erecting buildings with low energy consumption and low environmental impact, with the possible recovery of aggregates in the form of rubble produced by demolition which can be broken up and dried by means of a millimetre-gauge crushing process which can be performed in the facility or even on site.
In fact, the combination of wood panels with aggregate material contained in the panel 1 permits combining in the latter the high thennal insulation quality of wood with the thermal inertia quality possessed by the aggregate material. The functionality of the wall or of the ceiling or of the roof thus made up - if necessary perfected with the addition of the external ventilation chamber - in winter condition ensures a high degree of thennal insulation and in summer condition better environmental comfort due to the dispersal of the summer heat wave.
The advantages obtained by the present solution do therefore lead to construction, energy and economic savings which are an excellent solution for the building trade which, in this particular historical moment, is affected by the need to demolish, partially or totally and/or restructure, buildings that are by now old and affected by high energy consumption, and replace them with efficient and low energy consumption buildings.
The energy advantages do not only consist in managing internal environment comfort. In fact, the use of low environmental impact materials with very low production energy consumption and reuse of recycled materials results in this construction solution being used to erect buildings with a total energy consumption, and which therefore also comprise both the construction and management phases, below that of all the currently-used construction methods. With regard to economic advantages, these are obtained through: using very low cost aggregate materials; cutting the cost of disposing of demolition materials; the low thermal transmittance value of the building which results in very low energy consumption; and in the high inertia of the aggregate material, which allows reducing summer heating inside interiors and cutting heat requirements. The fact that the aggregate materials are mixed dry also has its advantages. In fact, at the end of the working life of the building, the material can again be reused without it having to be split up any further.
A further advantage of the use of the panel according to the invention is determined by the fact that the possibility of recovering and reusing the waste materials of previous demolitions also favours the preservation of the natural habitat. The latter does in fact appear less subject to actions of a mining type and to being disfigured by the removal of natural materials to be used for building purposes.
Besides overcoming the problem of demolition waste product disposal and/or transport, as regards restructuring, further advantages can also be obtained in terms of increase in internal volume of dwelling spaces. This is due to the fact that the dimensions of the new structures are more reduced, despite having better heat characteristics than the previous ones.
Last but no less important advantageous aspects of the invention concern fire safety. In fact, in case of fire, the wood structure of which the panel is made tends to bum but not collapse: hence greater accident-prevention safety for people inside the building structure or near to it. Furthermore, the presence of aggregate materials, such as the component pails of the panel itself, favours the incombustibility of the panel and increases fire resistance which hinders and slows down the spreading of the fire.
The invention thus conceived is susceptible to evident industrial application; it can also undergo numerous changes and variations, all of which falling within the scope of the invention concept; all the details can furthermore be replaced with technically equivalent elements.
