Description

Prefabricated residential module

Technical field of the invention

The present invention relates to the field of construction and more specifically a prefabricated module for residential use particularly light and economical.

State of the art

The demographic development encountered by all Western societies, but also by developing countries, gives a particularly critical dimension to the housing question.

It is therefore extremely important, in order to meet the growing needs in this field, to have easy techniques to implement and particularly economic.

The technique of prefabricated construction obviously provides a beginning solution to this problem since it allows to quickly raise buildings for residential use.

However, this technique remains very specialized in its implementation, which makes its dissemination still very confidential. It would be necessary to be able to push forward this prefabricated construction so as to allow everyone to implement it quickly to enable him to solve his housing problem.

It would therefore be extremely desirable to be able to have a fully prefabricated housing module, allowing multiple configurations, which

CONFIRMATION COPY would offer comfort, lightness, durability and, of course, that would be particularly economical to implement.

Such a wish is formulated even outside the crucial and sometimes dramatic context of housing that our societies experience. Indeed, even in a lighter context, that of tourism which is developing in many regions and even developing countries, it is also desirable to have a light, functional and sustainable solution to offer the public economic solutions for housing. temporary, and especially small hotel cells, which are economical and can be easily deployed on site with a minimum impact on the natural environment and the environment.

These are the problems that we propose to solve with the present invention.

Description of a preferred embodiment

We now describe a particular embodiment of a prefabricated module particularly functional, lightweight and economical to manufacture and maintain.

The description below will be particularly suitable for the realization of a prefabricated module intended for tourism, thus offering to its occupants all the modern functionalities that one can expect from such an establishment and which, moreover, presents an exceptional durability and this even under particularly difficult operating conditions.

Clearly, we can adapt the described module to the realization of a T1 type apartment, or even a larger apartment by combining different modules as will be explained below, in order to achieve more complex structures .

The prefabricated module which is described below is particularly economical to manufacture and lightweight in its structure.

For this purpose, it is exclusively made from seven constituent elements, described below, all from the same manufacturing process and; preferably exclusively made from panel comprising phenolic polyester resin.

This component is known in ships and aircraft for making thin and strong hulls. The inventors have discovered that it is possible to project much thicker layers of phenolic resin so as to drown, within one and the same panel, electrical sheathings in order to achieve, in one and the same manufacture, a complete prefabricated facade, particularly light (despite the thickness of the phenolic resin layer), economical and easy to implement.

It thus proposes a new structure of a prefabricated module made exclusively from such a material and which then leads to the possibility of producing a lightweight, economical, and particularly resistant and durable module.

Figure 9 particularly illustrates a first embodiment of the common structure of the seven elements which will be described below in more detail, based on the use of a projected resin.

It can be seen that the structure comprises a succession of elementary layers making it possible to produce a light and durable wall. Starting from the inside of the wall towards the outside, there is a first layer 91 of fiberglass, matt type Gel Coat well known to professionals in the construction of naves and aircraft, then a frame of aluminum of structure 92 which, and this is particularly advantageous, will be the only metallic element of the structure, followed by a large thickness - up to 10 cm - of projected resin, such as projected phenolic resin 93. On top of this, a structural aluminum frame 94 is again laid, then covered with one or more layers of Gelcoat mat for the finished appearance of the wall.

The phenolic resin used in this particular embodiment has a significant advantage because its mechanical characteristics in no way diminish when exposed to high temperatures, for example when a fire breaks out inside the module.

This wall has remarkable characteristics, especially in terms of sound and heat insulation, but also in terms of fire behavior. However, it will be possible to optionally add a fireproof panel, for example a wall panel M2 laminated surface Polyrey type or similar, which will provide additional protection, even if it is in fact not necessary because of intrinsic fire-fighting characteristic already present in the phenolic resin layer 93. As it appears in FIG. 9, the structure allows the realization of a plate, a facade or elements that can be used for the realization of all the constituent parts of a prefabricated economic module and offering characteristics lightness, durability and, which is far from negligible, is fully in line with the standards in force for hotels receiving public.

In addition, the external appearance of this structure can be enhanced by providing an additional layer enabling the inclusion of a photograph of a material of wood, marble or stone type, etc.

Alternatively, and according to a second embodiment (not shown in the figure), we can substitute the foam resin spray an expansive foam injected under vacuum between two resin cores, and which is glued. It is thus also possible to obtain, using a phenol-based foam or any product having comparable mechanical and fire-resistance characteristics, a panel having high mechanical strength and meeting the requirements of European regulations, ensuring good fire resistance without release of toxic fumes harmful to the health of the occupants of the module.

These panels can be made in many ways, manually or industrially, depending on the choice. According to a third embodiment, it is possible to make each gelcoat panel (2 faces, inner skin and outer skin), in which, inside these two skins, there is an expanded foam, a foil of high fire resistance ceramic, with introduction in this expanded foam, of extruded resin structure, double compartment (high current and low current) forming belt of the volume 4 sides, ceiling, side walls and floor, communicating for distribution, with connection to the Technical Sheath. Different assembly inserts, extruded resin are arranged inside these panels to allow screwing during assembly or disassembly of the housing module on the various operating sites. These panels are sealed with gel resin coat, also ensuring the aesthetic finish. The expansive foam can be made based on Phenol, but can also be replaced by honeycomb membrane panels made of resin, or by polyurethane foam injected by vacuum suction.

More specifically, the method described below will make a panel of this type that can advantageously be the partitions of the housing module. For this purpose, there is a mold defining the panel on the bottom and sides (as for a drawer), in which it is arranged inside the gelcoat on all sides. The ceramic is then placed and the extruded resin elements are placed for the passage of cables, screw-in and / or reinforcing resin inserts. Then comes to fix over a plastic membrane delimiting a volume provided with an inlet for the expansive foam injection and an outlet for connection to a suction device. In this way, by connecting the suction under vacuum, one can come to inject under vacuum expansive foam that fills the interstices and the internal volume of the panel. We then complete the whole by a gelcoat membrane ensuring the hermetic character of the panel and its aesthetic finish.

We now describe the use of such a panel or element for the production of a prefabricated module which has been illustrated in Figure 1a a base 10 having a lower plate 11 and an upper plate 12, both made by means of the structure described above in connection with Figure 9. The two plates 1 and 12 are separated by two rests 13 and 14 - they also made by means of the same structure, and delimiting cavities between the two plates. As seen in FIG. 1a, but also in FIG. 1b which shows another perspective of the floor element showing a bottom plate 11, the top plate has a shower tray 15 embedded in the phenolic resin thickness. , and further comprises several orifices for the flows water, including a drain hole 16 for the receiver and a drain hole 17 for a sink.

It should be noted that, in a particular embodiment, the shower tray can be covered with a cover so as to restore the flatness of the ground for the case where the occupant of the prefabricated module would not wish to affect the surface of the one to a pond.

As also seen, and will be described in more detail below, the lower and upper plates have a cutout disposed on the side of the door facade intended to receive a vertical technical duct passing from below upwards the prefabricated module, and which will be described in more detail below. In general, all the water-electricity pipes bring back to the volume delimited by this cut, as seen with the emptying tube 18 of the shower tray, so as to allow the location of all the equipment within the single sheath. present in the prefabricated module. In a particular embodiment, even the siphon of the shower tray will be disposed in the volume of the duct so as to allow maintenance operations directly from outside the module.

Figure 2a illustrates a view of a front panel 20 or left side panel of an embodiment of the prefabricated module. As indicated above, this second element is also achieved by means of projected phenolic resin, which will be of sufficient thickness to, on the one hand, ensure the rigidity of the wall and, on the other hand, allow the burial of electrical conduits for the distribution of electrical outlets, switches and other connectors.

The panel 20 has a few reliefs - such as the wall 22 - which can be used to define, as necessary, spaces on the wall and further comprises in its lower part a console 23 having the profile of a shoe for to slide between the lower plate 11 and the upper plate 12 of the base element of Figure 1. The console 23 thus ensures that the bonding of the floor element with the left side facade as squaring of the constituent elements of the future floor of the prefabricated module.

In the left side panel can be arranged prefabricated furniture elements, such as a sink 25, a bed applies 26, and various connectors (telephone, electricity, Ethernet) and switches - for example 27 and 28 - and electrical outlets 29.

As mentioned before, the electrical sheathing of the weak current distribution is embedded in the phenolic resin which at the same time ensures functionality, lightness and safety.

FIG. 2b is another example of a perspective of the left lateral wall showing better the detail of the console 23 and also the arrival of the electrical conductors 21 (having at their ends adequate connectors, eg standardized) in the volume of the technical sheath accessible from the outside. The electrical conductors arranged on the other side are used to power the roller shutter of the window facade. Figure 2 illustrates a left side of an embodiment of the prefabricated module.

Fig. 3 illustrates a perspective of a front or right side wall of an embodiment of a prefabricated module. The right side wall 30, made from projected phenolic resin, also has a console 33 in the form of a shoe, and allowing the bonding of the lower plate 11 and upper 12 of the base. This facade includes all the jacks and connectors for the installation of a kitchenette 32 with a cavity for a refrigerator and a closet 31. Nested in the phenolic resin, are the different electrical ducts for the distribution of strong and weak currents , and in particular the installation of a flat television 34 and its power supply plugs - electrical 35 and antenna plug 36, switches (such as switch 37) and various electrical outlets, in particular 38 and 39 . Figures 4 illustrates the roof element 40 which can be glued to the upper parts of the four facades of the module. The roof 40 may have, if necessary, a cutout 38 corresponding to the parallelepipedal volume of the technical sheath for connecting the fluids with an upper prefabricated module which would be, if necessary, located above. In the absence of such an upper module, the roof element 40 comprises a cover (not shown) for covering the cutout 38 and the technical sheath.

As indicated, the roof element 40 is also made by means of a sandwich structure composed of phenolic resin projected so that the weight of the roof will be particularly light.

FIG. 4b shows more clearly the internal structure of the roof element 40, where it can be seen that the latter is combined with a false ceiling, having the shape of a plate 41 made of projected phenolic resin, comprising the various ducts for the luminaires. A double fold 42 in the false ceiling delimits, on the side of the window facade, a space for receiving the shutter device. On the other side, the false ceiling also has a cut corresponding to the section of the volume of the duct passing through the prefabricated module from below upwards.

FIG. 5 is a perspective view of an embodiment of the prefabricated module, in which the roof element 40, with its cutout corresponding to the section of the technical duct, and the door 50 and right-side door facades 30 are seen As already seen from this perspective, the facade is, and this is a particularly advantageous element, comprise two doors, including the entrance door and a door intended to allow access, from the outside, to the volume corresponding to the technical sheath. This will result in considerable space savings since all the sensitive equipment, likely to be maintained, can be accessible from the outside.

FIG. 6 is a rear perspective view of an embodiment of the prefabricated module, in which the roof element 40 and the two window 60 and left-hand side windows 20 are seen in a similar manner as before. Referring now to FIG. 6, technical sheath 70 is described which provides all the essential functionalities of the prefabricated module and which, as has been specified, is particularly accessible.

Technical sheath 70 consists of two vertical plates 71 and 72, crossing on either side, from bottom to top, the prefabricated module and having two interior volumes delimited by means of an intermediate element having three flat sections 73, 74 and 75 respectively vertical, horizontal and vertical.

It follows that the technical sheath has two volumes or spaces, the first volume (left) is particularly tapered in its upper part and wide in its lower part. On the contrary, the second volume (right) is particularly tapered in its lower part and wider in its upper part.

The left volume is allocated to the flow of water - cold water, waste water, sewage - while the volume on the right is allocated exclusively to strong and weak currents.

It should be noted that the walls 71-75 of the technical sheath 70 are also made by means of the phenolic resin sandwich structure of FIG. 9, so that a lower cost is provided for homogeneous technical sheath with the rest of the module, which can be easily glued to the other components of the latter and, moreover, to the fire standards. Once glued, the rear face of the technical sheath corresponds to a wall of the bathroom of the module, and the right wall 71 completes the wall wall of the corridor, behind the entrance door of the same module. As can be seen in FIG. 5, and this is a particularly advantageous element for the maintenance of the module, the technical sheath 70 has its own front door so that any intervention on the functional elements of the module is directly possible since outside the prefabricated module. In a particular embodiment, the technical jacket comprises, in the "water flow" part, a water inlet pipe 77 comprising both in its lower part and upper connectors allowing the interconnection of the technical sheaths between different modules, and a stopcock 87. There are also sewage evacuations 78 (connected to a WC conveniently and cheaply attached to the other side of the back wall of the technical sheath) and water valves 79 and, very advantageously, the siphon 86 of the shower tray 15 which is thus deported in the technical sheath through a pipe of large diameter allowing the flow from the shower tray to the siphon. It should be noted that the rear wall of the technical duct serves to delimit the interior cabin of the prefabricated module and also serves to support a toilet thus communicating directly with the technical duct.

The volume on the right comprises, meanwhile, a heating / air conditioning unit 76 taking place on the horizontal section 74 of the intermediate element 73-74-75. On the other side of the wall 71, one can easily have all the control elements of the electrical part, including a general circuit breaker, division circuit breakers 82, various switches 83 (central lighting) and a convector heating-air conditioning 85 operating in cooperation with the air conditioning / heating unit 76. The various members are directly placed at the entrance of the passenger compartment of the prefabricated module, and therefore communicate directly with the technical duct since it is the same partition or wall 71 which ensures the delimitation. As we see, this is an arrangement is extremely convenient since the technical sheath at the same time ensures the delimitation of the passenger compartment (via the wall 71 and its rear wall), the delimitation of two perfectly disjoint volumes respectively assigned to water and electricity flows. Figure 8 shows how one can add an additional delimitation, to separate the rest of the room the volume of the bathroom, by means of a shower screen structure 80 particularly economical and easy to install. As can be seen in this figure, it is thus delimit, very economically, a particularly functional bathroom since the base 12 comprises, manufacturing, the shower tray and that one of the facades (the left side in Figure 8) can predispose the arrangements of the bathroom. So just add the complex 80, preferably with the door of the bathroom, to definitely complement the volume of the bathroom.

Figure 10 illustrates a perspective of the structure for vertical deployment of the modules according to the invention. For this purpose, use is made of a component base of four metal elements of "HN" type constituting a base 100 on which the prefabricated module can be installed. In a particular embodiment, two metal elements - a length 101 and a width 102 - are welded directly at the factory and the two halves of the base are bolted to the installation site. At the four corners of the base 100, there are four posts 120 having an "L" profile having in their upper part a bracket 130 intended to support an upper structure identical to that illustrated in FIG. 10, so as to allow vertical stacking of prefabricated modules. In a particular embodiment, the "L" profile of the columns is arranged to offer the shortest part of the "L" to the front and rear faces of the prefabricated module so as to facilitate the disengagement of a lower module. times this one in place within a vertical structure. In a particular embodiment, the frame 100 is made of extruded polyester resin to further reduce the weight of the structure.

As can be seen, the prefabricated module offers a great facility with regard to the "vertical" deployment and one can, at will, replace one module by another according to the needs. One can even imagine the organization of a hotel complex in which one would come, as necessary, come to position specific modules (for example offering services for people with disabilities) and to which the operator could resort of the complex. The "horizontal" deployment of prefabricated modules according to the invention is also extremely easy since it is sufficient to position as many modules next to each other to have either individual units or larger apartments with different rooms as shown in Figure 11 which illustrates a plan of space.

In a particular embodiment, the facades / walls 20 and 30 may be equipped with a communication door allowing two modules arranged next to each other to communicate together and, consequently, to enlarge the surface offered to the occupants of the modules.

The module allows a great flexibility, allowing its occupants to enlarge the surface according to needs and resources. Figures 12 and following show views, sections and elevations of the prefabricated module, so as to illustrate the great flexibility, ergonomics of the module.

FIG. 13 shows in particular the cooperation of the prefabricated module with its base 100 and its posts so as to allow the stacking of different modules to produce a structure of the R + 3 type, as illustrated in FIG. 21 .

Figures 14 and 15 respectively illustrate a section A-A 'of Figure 11 and an elevation of the facade B. FIG. 16 illustrates an elevation of the frontage B 'in situation with the structure for the vertical stacking of different modules. Figure 17 illustrates the window facade of the prefabricated module. The figure

18 illustrates the section BB 'of an embodiment of the prefabricated module. The figure

19 illustrates the section CC of an embodiment of the prefabricated module. Figure 20 illustrates the section DD 'of an embodiment of the prefabricated module.

The structure is easily removable and transportable, each of the panels being very light and having all the technical facilities of the housing module, including the bathroom. So, coming remove the front panel that has the entrance door, you can change the entire electrical installation including the air conditioning system. The module will be very easily removable and can be reinstalled at will in different places.

They can very easily be used in the hospitality sector, allowing their installation and disassembly as needed.
