79,276 Int. (:1. B60p 3/32; E04h 1/12; E04g 21/14 Us. or. 5269 14 Claims ABSTRACT OF THE DISCLOSURE In French Patent No. 1,372,468 there is described a method for improving the techniques of industrialisation of constructions for habitation which comprises manufacturing in the factory elements whose general shape is that of rectangular-sided caissons each of which corresponds to a distinct room or premises of a standard or typical dwelling, the various caisson elements adapted to constitute this standard dwelling having such dimensions as to be capable of being placed one inside the other or nested together so that the caisson representing the largest room can contain all of the other caisson elements of the standard dwelling.

This arrangement is completed by the choice of light materials for the construction of the sides of the caissons and has the advantage of rendering possible the transportation of the essential elements of a complete dwelling by a single vehicle.

According to the teaching of the aforementioned patent, the caisson elements, after their transportation to the site, are assembled on a reception surface which is arranged in such manner as to constitute a foundation element or floor for the dwelling. In order to increase the economical value of the method, the object of the present invention is to provide an improvement in that the floor of the dwelling is also pre-fabricated in the factory and so arranged that it can serve as a protective packing for the transportation of the caisson elements.

According to another feature of the invention, the floor or bed, which is preferably rectangular, comprises three parallel parts, namely a median part Whose width corresponds to the overall size of a pack of nested caissons and two lateral parts pivoted to the median part so as to be capable of occupying either a closed position in which they form two vertical side walls adapted to enclose the pack of caissons placed on the median part, or an open fiat position in which they can be locked and rendered rigid with the median part so as to constitute both a surface for mounting the dwelling and a floor adapted to be incorporated in the construction.

Once open on the site, the assembly thus constituted is placed in position on temporary blocks which subsequently receive the elements of the dwelling to be assembled and are finally integrated with the assembled dwelling in the framework of the building to be constructed, or directly on a foundation or the framework prior to the mounting of the elements.

The caissons are preferably obtained by the assembly "ice of panels which comprise an insulating core, for example of a foam of plastics material, both faces of which are connected to a facings or revetments, which can also be of plastic material and in particular polyester reinforced with glass fibers.

Transportation on a railway or highway vehicle of the fitted caissons protected inside the described foldable bed, can present a problem owing to their overall width which exceeds the regulation loading gauges of some countries.

Consequently, according to another feature of the invention, each caisson element can be divided preferably into the form of two half-caissons so that it is possible to form, by the nesting of lower half-caissons and upper halfcaissons, two distinct packs which, placed on the centre part of a closed bed, can be loaded one behind the other on a highway or railway vehicle and constitute a load whose overall width is within the regulation loading gauges.

When assembling, two complementary half-caissons are interconnected in accordance with a method which depends on the nature of the panels constituting the halfcaissons, for example by welding or adhesion.

Further features and advantages of the invention will be apparent from the ensuing description with referen to the accompanying drawings.

In the drawings:

FIG. 1 is a diagrammatic view of a series of elements, each pre-fabricated in the form of a caisson and nested one inside the other and corresponding to a standard dwelling;

FIG. 2 is a perspective'view of a caisson for the construction of one dwelling room;

FIG. 3 is a diagrammatic elevational view of the manner of loading a series of nested caissons on a trailer;

FIG. 4 is a view of a detail showing the pivot of the bed shown in FIG. 3 and means for locking this pivot;

FIG. 5 is a plan view of one example of a dwelling constructed of the elements shown in FIG. 1;

FIG. 6 is a diagrammatic view of a bare floor and a roof covering an individual house corresponding to the plan shown in FIG. 5;

FIG. 7 is an end elevational view of the roof shown in FIG. 6; 1

FIGS. 8 and 9 are horizontal sectional views of panels employed in the construction of the caissons, these panels respectively constituting a partition wall and a frontage wall;

FIG. 10 is a vertical sectional view of a panel;

FIGS. 11 and 12 are views of the connection of a frontage panel respectively with a floor and a ceiling carried by the roof structure;

FIGS. 13 and 14 are views respectively in horizontal section and vertical section of the assembly of two adjoining partition panels;

FIG, 15 is a horizontal sectional view of the assembly of two frontage panels disposed in end-to-end relation;

FIG. 16 is a view of a trailer coupled to a highway tractor and loaded with a pack of caissons for an individual house contained in a folded floor-bed assembly;

FIGS. 17-19 are perspective views of the main stages of the construction of an individual house;

FIG. 20 is a view similar to FIG. 16, the pack of caissons being intended for the construction of a dwellin plan in FIG. 5. The largest caisson element A, constituting the lounge, contains all the others.

As shown in FIG. 2, each caisson element is composed of three panels 3, which form the walls of the rooms or cells, and is open at the top and bottom.

In FIG. 3, the pack P of caisson elements is shown loaded on edge on a trailer 8 coupled to a highway tractor. The pack P is supported on the chassis 11 through a bed 12 which comprises a centre part 13 bearing against the chassis 11 and two wider lateral parts 16 which are pivoted at 17 to the centre part so that these two lateral parts can be raised to a vertical position and constitute two side walls which form with the centre part 13 a container surrounding the pack P of caisson elements during transportation.

The bed 12 is adapted to constitute, after the locking of the pivot 17, the floor of the dwelling to be constructed from the elements A] of the assembly P. In the embodiment shown in FIG. 4, the pivots 17 comprise a pin 53 inserted in tubular sleeves 54 which are alternately welded to one and the other of two L- section members 56, 56 fixed to the parts 13 and 1-6 respectively of the bed 12 in the region of the upper face of the latter. A roundsection rod 58 connects the L-section members to identical L-section members located in the lower part (not shown). The pivots 17 are locked by means of welded pins 59 which interconnect the vertical flanges of the pairs of L-section members 56 with interposition of an adjusting block 61.

In FIG. 6, the floor 12 is in its extended position on a foundation (not shown) and incorporated in an individual house having a roof 19 resulting from the assembly of three longitudinal elements 21, 22, 22 (shown in elevation in FIG. 7).

FIG. 8 shows by way of example a composite panel 43 which is employed for constructing partition walls 3 for the caisson elements A]. This panel comprises an insulating core 44, for example of phenolic foam, to which are connected two revetment sheets 46, for example of polyester reinforced by glass fibres. In the panel 47 shown in FIG. 9, which is supposed incorporated in a frontage, the outer revetment sheet 48 consists of, for example, an enameled sheet or a marble slab.

As shown in FIG. 10, U-section elements 49 straddle the upper and lower edges of a panel 43 or 46 which is incorporated in a caisson element. A tie bar 52 is tightened between the bottoms 49a of these U-section elements by means of tightening nuts 51. The elements 49 serve to assemble the corresponding panels by means of bolts 53 with the floor 12 (FIG. 11) and with the ceiling 54 supported by an element of the roof 22 (FIG. 12).

FIG. 11 shows that the floor 12 consists of a core having a honeycomb structure 12a, for example containing aluminium, connected to the cover sheets 12b.

In FIG. 13, vertical tie-bars 52 are also provided within two adjoining panels 43 for assembling the latter. These tie-bars extend in rectangular tubes 56 which are embedded in the insulating material 44 and flush with the free face of the outer revetment sheet 46 through an opening 57 in the latter. The panels are clamped together by means of nuts 51 to plates 58 which cover the bottom 49a of the respective elements 49 in the region of the adjoining tubes 56. U-shaped fasteners 59, having branches penetrating the insulating material 44, also contribute to the assembly.

To assemble two frontage panels 47 in end-to-end relation, a similar arrangement is shown in FIG. 15.

The tractor-trailer unit 8 shown in FIG. 16 comprises, as in FIG. 3, a pack P of caisson elements contained in a folded bed 12 and moreover elements 21a, 22a which are also in the bed 12 and constitute component parts of the roof 19 of an individual house. After unloading the assembly of elements carried by the bed 12, the latter is in turn unloaded, placed in position on the foundation provided for this purpose and then opened out (FIG. 17).

The pivots 17 (FIGS. 3 and 4) are locked and then the individual caisson elements A] (FIG. 18) are interconneeted and connected to the floor 12 in accordance with a plan which is for example that shown in FIG. 5. The elements 21a, 22a of the roof 19 are finally placed in position and assembled with the panels of the caisson elements (FIG. 19).

The combination according to the invention of a pack P of caisson elements and a bed 12 (FIGS. 20 and 21) can obviously be employed for the construction of dwellings in a collective building. On top of the already-constructed part of the building 30 (FIG. 21) a complete dwelling 31whose caissons have been assembled with the corresponding bed-floor 12 on an assembly surface can be placed in position after having been attached by a sling 33 to the hook 34 of a crane. Framework elements 36 and bracing elements 37 must then be provided for ensuring that the structure has the required stability.

It is clear that in the case of a collective building, each floor 12 receiving a complete dwelling 31 can be employed or constitute the ceiling of a subjacent dwelling 35.

Instead of having a height equal to that of the rooms of the dwelling to be constructed, the caisson elements can have merely a fraction of this height. Each dwelling could thus be constructed by the assembly of half-caissons which are, if desired, provided with a floor or ceiling element. The construction could be then transported to the site by disposing the two packs P P of half-caissons Within a bed 12 (FIG. 22).

Although a specific embodiment of the invention has been described, many modifications and changes may be made therein.
