The module has extreme lightness associated with sufficient rigidity and is substantially unaffected by bad weather and is easy to assemble.

Description

SECTIONAL HABITATIONAL MODULE
TECHNICAL FIELD
The present invention relates to a sectional habitational module.
BACKGROUND ART
Sectional habitational modules are known which include a plurality of pressed sheet metal parts which are connected together (for example by bolts) to form a plurality of spaces adapted to be inhabited.
These habitional modules have a series of disadvantages: they are rather heavy and difficult to transport, can easily be damaged by atmospheric agents, do not provide good acoustic and thermal insulation and are relatively costly.
DISCLOSURE OF INVENTION
The object of the present invention is to provide a habitational module which solves the problems of known habitational modules.
This object is achieved by the- present invention which relates to a sectional habitational module including a plurality of interconnected panels defining at least one space, characterised in that the panels comprise a layered structure comprising at least one three- dimensional textile formed from two textile sheets facing each other and connected together by a plurality of extensible threads; the three dimensional textile being impregnated with resin.

Figures 6 to 11 are transverse sections illustrating several parts joining the panels.
BEST MODE FOR CARRYING OUT THE INVENTION
In Figure 1 a sectional habitational module is generally indicated 1 and includes a plurality of interconnected panels 5 of synthetic material defining a series of spaces 8 designed to be inhabited. The panels 5 are placed with their straight peripheral edges 10 close together and are connected together by profiled metal sections 15 which, join the peripheral parts of the panels 5 firmly together.
The panels 5 form the peripheral walls 20, the internal partition walls (not illustrated) , the roof 22 and the inner floor (not illustrated) of the module 1 defining a habitation.
The panels 5 have a layered structure including a three- dimensional textile impregnated with resin.
Figure 2 illustrated a first type of panel (indicated 5a) which comprises a three-dimensional textile 30 formed from two facing textile sheets 33 and 34 connected together by a plurality of extensible threads 36.
The textile 30 is impregnated with solidified resin so that the sheets 33 and 34 form two flat rigid . faces joined together by the threads 36 which extend substantially perpendicularly between the sheets 33 and 34.
The panel 5a is conveniently of the type described and illustrated in Italian patent application number TO-91A000397 filed on 29 May 1991 by the same applicant and the required parts of the content whereof are incorporated herein simply for reference; it is manufactured by a process (refer to Figure 4) including a first phase in which a layered structure 40, soaked with resin, is inserted between a first die 42 and a second die 43 of a press 45; this layered structure 40 includes the three-dimensional textile 30 and at least one pair of plates 47 and 48 face to face with sheets 33 and 34 of the textile 30 on the outside of the structure 40.
The dies 42 and 43 have means for attaching the plates 47 and 48 to their surfaces and have heating resistors 44 for accelerating the polymerisation of the resin.
In a second phase, the dies 42 and 43 are closed to a certain extent, the three-dimensional textile 30 is pressed between the plates 47 and 48 and the resin impregnating the sheets 33 and 34 distributes itself between the parts in contact and also permeates the threads 36 uniformly.
In a third phase, the plates 47 and 48 are firmly attached to the dies 42 and 43 (for example by means of a vacuum system) .
In a fourth phase the dies 42 and 43 are reopened through a predetermined distance within the limit of the natural elastic recovery of the three-dimensional textile 30 due to the action of the combination of threads 36 which tend to straighten.
In a fifth phase the resistors 44 are activated and heat the outermost parts of the structure 40 causing partial polymerisation of the resin between the plates 47 and 48 and the outer sheets 33 and 34 of the three-dimensional textile 30 while the resin impregnating the threads 36 remains in a substantially plastic state.
In a sixth phase, the dies 42, 43 are opened to a predetermined distance to move the sheets 33 and 34 away from each other and extend the threads 36 so as to form a partially hollow structure inside.
In a seventh phase the structure is held clamped between the two dies 42,43 and heated until the polymerisation of the resin is complete.
In an eighth phase, the plates 47 and 48 are released from the surfaces of the dies 42, 4.3 which are completely opened; finally, the layered structure 40 forming the panel 5a is removed from the press.
The plates 47 and 48 may subsequently be detached mechanically and removed from the layered structure 40.
Figure 3 illustrates a second type of panel 5b which comprises a three-dimensional textile entirely similar to the textile 30 and hence formed from two facing textile sheets 33 and 34 connected together by a plurality of extensible threads 36.
In this textile 30, the space between the sheets 33 and 34 is filled with a solidified expanded resin 50 injected between the sheets 33 and 34 themselves under pressure.
The panel 5b is conveniently of the type described and illustrated in Italian patent application no 12441-A/90 filed on 26 March 1990 by the same applicants, the required parts of the content whereof are incorporated herein simply for reference;- it is formed (refer to Figure 5) by the insertion of a layered structure 51, including at least the three-dimensional textile 30 impregnated with resin, between a first die 52 and a second die 53 of a press 55.
The dies 52 and 53 are closed and the expanded resin 50 (or another solidifiable expansible fluid) is injected under pressure between the sheets 33 and 34 which are pressed against the walls of the dies 52 and 53.
Subsequently, the dies 52 and 53 are heated to cause the polymerisation of the resin 50 injected between the sheets 33 and 34. Finally, the dies 52 and 53 are re-opened and the layered structure forming the panel 5b is removed from the press 55.
The layered structure 51 may further include two outer textile sheets impregnated with a thermosetting resin and face to face with the sheets 33 and 34 or outer plastics or metal sheets, conveniently with the interposition of an adhesive layer.
Figure 6 is a cross-section of a first type of profiled section 15a used to join together two flat panels 5 disposed parallel and adjacent each other; the profiled section 15a has a double-T section and defines two substantially U-shaped, aligned channels 60 housing respected peripheral portions of the panels 5.
Figure 7 is a cross section of a second type of profiled section 15b used to join two flat panels 5 disposed perpendicular to each other; the profiled section 15b has a substantially L-shaped section defining two substantially U-shaped channels 62 at right angles housing respective peripheral portions of the panels 5.
Figure 8 is a cross-section of a third type of profiled section 15c used to join two flat panels 5 disposed perpendicular to each other; the profiled section 15c has a substantially Y-shaped section and defines two substantially U-shaped channels 64 at right angles housing respective peripheral portions of the panels 5.
Figure 9 is a cross-section of a fourth type of profiled section 15d used to join to flat panels 5 disposed so that they intersect at an acute angle; the profiled section 15d has an essentially V-shaped section and includes a first wing 67 defining an inclined U-shaped channel 68 housing a peripheral portion of a first panel 5 and a second wing 70 defining an inclined U-shaped channel 71 housing a peripheral portion of a second panel 5.
The wings 67 and 70 are joined together by a screw 75 which passes two coaxial consecutive through-holes 76 and 77 formed in respective front portions of the wings 67 and 70; the screw 75 has one end screwed into a hole in a plate 79 which presses against inner portions of the wings 67 "and 70.
Figure 10 illustrates a profiled section 15f used to join together three panels 5 (conveniently constituting two side walls and a ceiling portion of the habitational module 1) . The profiled section 15f includes a first vertical portion 90 having an essentially L-section and defining two U-shaped channels 92 at right angles and housing respective peripheral portions of the panels 5, and a second portion 95 firmly fixed to an upper end of the portion 90. This portion 94 has a channel 96 which extends in a horizontal plane perpendicular to the portion 90 and houses peripheral portions of a panel 5 which acts as a ceiling.
It is clear from the above that . the present invention solves the disadvantages of known habitational modules since it is very light (and hence easy to transport while being sufficiently rigid) , is almost entirely insensitive to atmospheric agents, is sufficiently thermally and acoustically insulating, and is easy and quick to assemble and take apart.
It in fact suffices to join the various panels 5 together by means of the profiled sections 15 to form the walls, floors, ceilings, etc. Openings for windows, doors, etc may also easily be formed in the panels 5 with conventional tools.
The habitational module 21 may thus be constructed by only two persons who can handle the various panels 5 even without lifting means and without having to make through- holes.
Electrical, water and sanitary services may be formed im a space in the floor foundation which is easily accessible, as shown schematically in figure 11, in which this space 99 is illustrated and defined by a first base panel 100 and a second panel 103 located above and parallel to the panel 100 and serving as a floor. The panels 100 and 103 are connected by a profiled metal section 105 defining two channels 109 and 110 of substantially U-section disposed parallel to each other and housing respective end portions of the panels 100 and 103.
More particularly, the habitational module is to advantage usable to form a readily transportable housing which can be installed, for example, in tourist villages, camp sites, and building yards.
The module is also adapted to provide housing which is substantially temporary but quick to install, and usable for example for housing refuges or populations hit by earthquakes.
Finally it is clear that modifications and variations may be made to the present module without thereby departing from the protective scope of the present invention.
The profiled sections 15 for example may have different shapes from those described and may be made equally well from plastics material or metal. The panels 5, moreover, may also be made with curved profiles (in particular the panels 5b of Figure 3) . The panels 5 may have outer coating sheets for decorative purposes. Insulating materials such as, for example, expanded phenolic foams, may be injected into the panels 5a of Figure 2. The panels 5 are always made from fire-resistant material with low toxic omissions in accordance with current standards for materials in the building field.
The panels 5 may also have cavities and internal spaces (particularly tubular spaces) for the passage of cables, tubes or metal strengthening elements.
Furthermore, with reference to the panel 5a Figures 2 and 4, in order to enhance the difference between the polymerization of the resin impregnating the sheets 33 and 34 of the textile 30 and that impregnating the threads 36, a catalyst may be spread on the surfaces of the plates 47 and 48 which are to contact the impregnated sheets 33 and 34 or directly on the sheets 33 or 34 themselves before the layered structured 40 is placed between the dies 42 and 43.
Thus the greater reactivity of the resin in the zones of contact between the sheets 33 and 34 and the plates 47 and 48, which is already increased by the greater provision of heat, is further increased compared with the reactivity of the resin impregnating the threads 36 by the local presence of a greater quantity of catalyst, and hence the time needed for the resin to polymerise and form a firm connection between the outer contact surfaces of the three dimensional textile 30 is reduced, this firm contact ensuring good extension of the threads 36 in the subsequent phases of progressive opening of the press 45.
.Conveniently, a methyl-ethyl-ketone peroxide may be used as the- catalyst for a polyester resin, in percentages, for example, of up to 3%, acidic solutions may be used for phenolic resins in percentages, for example, of up to 15%, and amide-based resins may be used for epoxy resins in percentages, for example, of between 30% and 50%.
The panels 5 could also be constituted by a plurality of superposed layers of three-dimensional textiles 30; conveniently a catalyst may be spread between the facing surfaces of these layers, for example between the sheets 33 and 34, to cause local acceleration of the polymerisation of the resin and the firm interconnection of the facing surfaces of the various layers so as to ensure the extension of the threads 36 within the various layers during the phases in which the press is opened progressively. In' addition, the electrical heating resistors 44 for the dies 42 and 43 could be replaced by other means for accelerating the polymerisation of the resin.
