Description
- The invention relates to a large-dimension, self-supporting, rigid hollow body that is designed for the production of structures and structures that are produced from one or more of such hollow bodies. It also relates to the process for the production of such structures.
- The document EP 0252072 describes a process and a device for the production of hollow bodies that are made of concrete and that are reinforced with continuous fibers. According to this process, the fibers are impregnated with water, the fibers are passed into a cement milk, the fibers are wound under tension into at least one layer, on a layer that consists of a mixture of cement and chopped fibers, whereby the concrete has been prepared from a siliceous material that has a fine grain size, and the composite product that is thus obtained is hardened at least partially before withdrawing it from said mandrel. The device comprises at least two tanks for the baths for impregnating fibers that can move in a direction that is parallel to the axis of the mandrel, a tilting arm that is equipped with a device for projecting the mixture of cement and chopped fibers and making it possible to apply the fibers under tension on the cement-coated mandrel. The hollow body consists of a prestressed concrete that is reinforced with fibers, whereby said concrete consists of a siliceous material that has a fine grain size and that has a fiber content that ranges up to 10% by weight and more of the final product that is obtained.
- The document GB 2068820 describes a non-planar body that is reinforced by means of glass fibers. This body is tubular or U-shaped or pseudo-U-shaped. It comprises successive superposed layers. First, the body is produced flat, and then it is shaped as desired in a cooling fixture.
- The document BE 1010457A4 describes a process for the production of hollow or flat bodies from cement mortar that is reinforced with fibers that are impregnated with acrylic polymers. In this process, a flange is used at each of the ends of the mandrel, continuous fibers are then wound around the mandrel in the form of fabric or netting that forms a mesh in warp and weft, impregnated with polymers that are preferably previously dried or polymerized with a cement mortar or any other binder.
- The document EP 1433581 describes a structure and a corresponding production installation. It is a matter of obtaining a uniform application of the hardening composition in such a way that the product has a homogeneous surface that reduces the risk of microcracks and that increases the quality and the solidity. In addition, it is proposed to implement natural fibers.
- The document WO2006130047 describes an installation for production of structural modules that comprises a rotary platform on which is installed a template that is reinforced with flanges, coils with continuous and infinite fiber, a device for the application of hardener, whereby the template is produced so as to be able to be compressed and the flanges to be removable. The device for application of the hardener is attached to a movable carriage that is installed on a straightedge, and it consists of a guide on which is attached a hose with a nozzle for supplying hardener, an oscillating block that is attached to the straightedge ensuring the nozzle a constant perpendicularity with the surface of the template, and an equidistance to the latter and a counterweight. The fiber of the coils is an alkali-resistant fiber, and a device for supplying binder onto the glass fiber that is wound on the template is provided.
- The document FR 1545241 describes a process for construction and prefabricated parts made of concrete or reinforced concrete for building, in particular for building framing. In this complex production, framing elements and beams are provided. By contrast, annular flanges that comprise holes that can work with elements for attachment by bolting or screwing are not provided.
- The
document FR 2 373 649 relates to improvements to the modular structures for marginal housing. Strictly speaking, this document does not describe a self-supporting hollow body, whereby the boxes form front elements that have to be combined with other panels. As above, annular flanges that comprise holes that are able to work with attachment elements by bolting or screwing have not been disclosed. - The
document FR 2 282 979 describes a process and a machine for the production of three-dimensional modules. A rotary matrix that forms a male mold is provided. This document does not reveal that the module includes annular flanges that comprise holes that can work with elements for attachment by bolting or screwing. - The cited documents, however, attempt to describe an actually operational technique.
- The invention takes advantage of the technique of the known field that consists in winding fibers on and around a mandrel while depositing on the latter a coating and resistance material that is based on concrete or the like, able to be deposited in the liquid state and then to harden, so as to form a hollow body that is made of concrete or the like, comprising a thin wall that is generally cylindrical in shape relative to an axis and two end flanges that are directed toward the outside, forming a one-piece unit that has an inside empty space with two end openings, whereby such a body is designed for the production of structures. The purpose of the invention is quite particularly to make this technique truly operational.
- In particular, the purpose of the invention is:
-
- To take advantage of the flanges,
- To allow the installation of elements for circulation and/or for distribution of electricity or electronics, or liquid or gaseous fluids and/or for the housing of means of thermal insulation and/or soundproofing means,
- To be able to produce an infinite variety of structures in particular comprising a number of juxtaposed or superposed bodies and/or one or more walls for concealment of the end openings of the bodies,
- To produce such structures by a simple, rapid, and inexpensive process that does not require a significant preparation of the site where they are to be installed or a heavy and complex infrastructure.
- More generally, the ultimate purpose of the invention is the production of modular structures that:
-
- Are suited to all of the standards and specifications on matters of city planning
- Are fire- and corrosion-resistant
- Have an excellent level in terms of heat and acoustic insulation
- Have minimal upkeep and maintenance
- Have a high mechanical strength that is particularly suited to zones with high seismic activity
- Are such that they require optionally little—if any—foundation
- Are easily transportable from one site to another
- Are such that the manufacturing installations can be mounted on vehicles
- Are such that they make possible a standardization of the finishing and equipment
- Are at the same time progressive, inelastic, and variable
- Are sources of savings.
- For this purpose, and according to a first aspect, the invention relates to a large-dimension, one-piece, self-supporting, rigid, hollow body that is designed for the production of structures, comprising a thin wall that is generally cylindrical in shape relative to an axis and two end flanges that are directed toward the outside that projects relative to the extrados of the cylindrical wall, forming an inner empty space with two end openings, made of coating and resistance material that is based on fiber-reinforced concrete, characterized in that the two end flanges have an annular axis shape, adapted to the shape of the cylindrical wall, and comprise attachment means in the form of holes that can work with the attachment elements by bolting or screwing, for the rigid attachment to one and/or the other of the flanges, a flange that is adjacent to an adjacent, analogous second body and/or a concealment wall, so as to allow the production of structures in a modular and flexible way.
- According to one characteristic, the flanges comprise means of attachment in the form of holes that can work with attachment elements by bolting or screwing and means of attachment of the flanges that include position-regulating means.

This space forms housing means for elements for circulation and/or for distribution of electricity or electronics, or liquid or gaseous fluids, and/or the housing of means of thermal insulation and/or soundproofing means.
- According to one characteristic, the hollow body is a microconcrete or the like that is reinforced with continuous glass fibers that are oriented in a cylindrical way like the cylindrical wall and can be found under a slight prestressing, whereby the microconcrete and the fibers are in superposed thin layers, with the concrete being able to absorb the compression stresses, and the fibers being able to absorb the tensile stresses.

- According to one characteristic, the structure comprises elements for insulation—against water, air, noise, dust, etc.—that are interposed between two adjacent flanges of two adjacent bodies.
- According to one characteristic, the structure comprises at least one concealment wall that is attached to a flange of a body of the structure. The concealment wall constitutes an outside wall (façade) or an inside wall (partition) of the structure.
- According to one characteristic, the structure comprises a space between two juxtaposed or superposed adjacent bodies whose peripheral surfaces of flanges are in contact, whereby this space is left empty or forms housing means for elements for circulation and/or for distribution of electricity or electronics, or liquid or gaseous fluids and/or housing for means of thermal insulation and/or soundproofing means.
- According to one characteristic, the structure is characterized by the combination between, on the one hand, the space between two juxtaposed or superposed adjacent bodies that form housing means for elements for circulation and/or for distribution of electricity or electronics, or liquid or gaseous fluids, and, on the other hand, the cylindrical wall of the body in that it comprises or forms or helps to form housing means for elements for circulation and/or for distribution of electricity or electronics, or the liquid or gaseous fluids.
- According to one characteristic, the structure comprises a wall that is attached to a body, able to constitute the floor or the suspended ceiling of the structure—or the structural part that is produced using the body. The space between the soffit of the cylindrical wall and the wall that is attached to the floor or ceiling forms housing means for elements for circulation and/or for distribution for electricity or electronics, or liquid or gaseous fluids, and/or the housing of means of thermal insulation and/or soundproofing means.
- According to a third aspect, the invention relates to a process for the production of a self-supporting structure as it was just described, in which:
-

structure 2 comprises, as appropriate, a singlehollow body 1 or several bodies for the most important structures. It comprises, if necessary, one ormore concealment walls 3 that can comprise one ormore openings 3 a, such as the opening of a door or a window or a passageway. - The same type of
hollow body 1 makes possible the production of an infinite variety ofstructures 2, both by their nature and by their arrangement, and finally their aesthetics. - Such a
structure 2 can be produced, i.e., the body orbodies 1 installed, without the necessity of producing foundations, which, combined with the rapidity of assembly, makes the invention well suited to the case where thestructures 1 have to be produced immediately. - The
hollow body 1 comprises athin wall 4 that is generally cylindrical in shape relative to anaxis 5 and twoend flanges 6, directed toward the outside. - The
hollow body 1 is one-piece, and it has an innerempty space 7 with twoend openings 8 where theflanges 6 are located. - Such a
hollow body 1 is made of coating and resistance material that is based on concrete or the like m and that is reinforced with fibers f. - A
flange 6 has a general annular shape ofaxis 5, in correspondence with or adapted to the shape of thecylindrical wall 3. - The
flange 6 comprises aprimary part 9 and astub 10 that is manufactured as a single piece. - The
primary part 9 is in the general shape of a flattened hollow cylinder, and it is designed to be visible in thehollow body 1 once produced. - The
stub 10 extends in the axial direction from atransverse surface 11 of theprimary part 9. Thestub 10 takes up inside radial space that is identical or close to the inside radial space of theprimary part 9. Its outside radial space is small compared to the outside radial space of theprimary part 9. - The

This arrangement makes it possible to adjust with precision the relative position of two analogous adjacenthollow bodies 1, juxtaposed in the extension of one from the other and the relative position of aconcealment wall 3 relative to the hollow body that supports it. - These structural arrangements make possible the production of
structures 2 in a modular and flexible way. - In contrast, the

The composition between the twohollow bodies 1 of a space 19 that is located on the outside of saidhollow bodies 1 is the result. - According to one embodiment, the
flanges 6 comprise or form or help to form removable attachment means of an element for handling thehollow body 1 during its production, its movement, its storage, or its mounting. Such attachment means can come in the form of openings. - According to one embodiment, the
cylindrical wall 4 of thehollow body 1 comprises or forms or helps to form housing means 20 forelements 21 for circulation and/or for distribution of electricity or electronics, or liquid or gaseous fluids, but also means of housing ofmeans 22 for thermal insulation and/or soundproofing means. - The space 19 between two
hollow bodies 1 constitutessuch means 20. These means 20 then consist of a passageway between theextrados 18 of thecylindrical wall 4 and another exogenic wall that is located on the outside of thehollow body 1 that is being considered, namely theextrados 18 of thecylindrical wall 4 of a another adjacent hollow body. - These means 20 can also consist of a
hollow reserve 23 that is arranged in thesoffit 24 of thecylindrical wall 4. - These means 20 can also consist of a passageway that is formed between the
soffit 24 of thecylindrical wall 4 and another exogenic wall that is located inside the hollow body. Such a wall is, for example, a wall that is attached to thefloor 25 or a wall that is attached to theceiling 26. - According to one embodiment, the
cylindrical wall 4 of thehollow body 1 comprises or forms or helps to form means for positioning and/or attaching functional and/or decorative elements that are designed to be part of thestructure 2. Such functional and/or decorative elements are, for example, movable property, pieces of furniture, household appliances or heating appliances, or else elements for circulation and/or for distribution of electricity or electronics, or liquid or gaseous fluids. - According to one embodiment, the
soffit 24 of thecylindrical wall 4 of thehollow body 1 comprises or forms or helps to form projecting support means 27, designed to support an attachedwall 25 that is able to constitute the floor (false floor) of thestructure 2 or an attachedwall 26 that is able to constitute the (false) suspended ceiling of saidstructure 2. - In such a case, there is a space between the soffit of the cylindrical wall and the wall that is attached to the floor or the ceiling, whereby said space forms means 20 of housing for
elements 21 for circulation and/or for distribution of electricity or electronics, or liquid or gaseous fluids, and/or the housing ofmeans 22 for thermal insulation and/or soundproofing means, as it was indicated above. - According to one embodiment, the
hollow body 1 is made of microconcrete or the like m that is reinforced with continuous glass fibers f for the like that are oriented cylindrically like thecylindrical wall 4, i.e., around theaxis 5. Such fibers f are arranged so as to have a slight prestressing. - The microconcrete m and the fibers f are deposited in thin superposed layers so as to reach the desired thickness that is calculated based on desired performance levels.
- In such an embodiment, the concrete m is essentially able to absorb the compression stresses while the fibers f are essentially able to absorb the tensile stresses.
- In one embodiment (
FIG. 8 ), thehollow body 1 has a homogeneous structure in its thickness, which means that it has a series of layers of concrete m and fibers f as indicated above. - In another embodiment (
FIG. 9 ), thehollow body 1 has a sandwich-type heterogeneous structure in its thickness that comprises anouter part 28 and aninner part 29, each made of microconcrete or the like m that is reinforced with continuous glass fibers or the like f and one or more functionalcentral parts 30 with mechanical or protective reinforcement, in particular thermal insulation or soundproofing. - In one embodiment, the
hollow body 1 has a straight cross-section that is generally square or rectangular, pseudo-square or pseudo-rectangular in shape (FIG. 5A ), or trapezoidal or pseudo-trapezoidal in shape (FIG. 5B ), with “broken” angles 1 a (FIG. 6A ) or roundedangles 1 a (FIG. 6B ). - With such an embodiment, and as
FIG. 4 shows it, twoparts 4 a of thecylindrical wall 4 that are face to face and parallel to one another are designed to form the lower part and the upper part, respectively, of thestructure 2, and are placed horizontally or approximately horizontally. On the other hand, twoother parts 4 b of thecylindrical wall 4 that are face to face are designed to form two walls of the structure. These walls are, in the general case, placed vertically or approximately vertically. However, the flexibility of the invention makes it possible to consider inclined walls by means ofhollow bodies 1 that have a straight cross-section that is generally trapezoidal or pseudo-trapezoidal in shape (FIG. 5B ). - In general, the surfaces of the
soffit 24 and theextrados 18 are planar or essentially planar. - In one embodiment, the
hollow body 1 has an axial length and transversal dimensions on the order of 3 to 5 meters, and more specifically, an axial length on the order of 4.5 meters and transversal dimensions on the order of 3.3 and 4 meters, respectively. - In one possible embodiment, the
hollow body 1 is equipped—from production—with outfitting elements or household furnishings. - The process for the production of such a
hollow body 1 is now described. - In this process, an installation is used that comprises a
mandrel 31 that forms an inner template for thehollow body 1. - Such a
mandrel 31 has anoutside surface 32 whosesoffit 24 of thehollow body 1 is complementary. Consequently, in line with thehollow body 1, themandrel 31 has a straight cross-section that is generally square or rectangular, pseudo-square or pseudo-rectangular, trapezoidal or pseudo-trapezoidal in shape with rounded orbroken angles 31 a (FIGS. 17A and 17B ). - Taking into account that when the
hollow body 1 is produced, it is carried by themandrel 31, it is suitable to provide to the axis of themandrel 31 the same numerical reference as that of thehollow body 1, namelyaxis 5. - Such a
mandrel 31 is rigid overall. So as not to be too heavy, since it has to be moved, it is preferably essentially hollow and made of a material that is as light as possible, for example wood. - It is understood that it is possible to use different mandrels corresponding to different shapes or dimensions of the
hollow body 1 that is to be produced. - The
mandrel 31 comprises anoutside surface 32 with reduced adhesion on thesoffit 24 of thehollow body 1 so as to be able to extract saidhollow body 1 from themandrel 31 without too much difficulty by axial pulling. - For this purpose, either the
mandrel 31 comprises anoutside surface 32 with reduced adhesion by its very nature or, at the beginning of the process for production, theoutside surface 32 of themandrel 31 is coated by an anti-adhesive or slippery material, for example with a grease base. - In another embodiment, there is a
deformable mandrel 31 in a short run, enough to “detach” theoutside surface 32 of the mandrel from thesoffit 24 of thehollow body 1, between an expanded state for the production of thehollow body 1 and a retracted state in which at least a part of theoutside surface 32 of the mandrel is separated from thesoffit 24 of the hollow body 1 (FIGS. 17A and 17B ). - With such an embodiment, the installation comprises means 33 for handling said deformation of the
mandrel 33, as well as means for controlling said maneuvering means 33. - In the embodiment that is depicted in
FIG. 17A , thewalls 34 of themandrel 31 are articulated and arranged in a deformable way between an expanded state in which the walls are planar (in dotted lines in the figure) and a retracted state in which the walls between them form a flattened V (in solid lines, whereby the deformation has been accentuated for better understanding). - In the embodiment that is shown in
FIG. 17B , themandrel 31 comprises aninside resistance structure 35 and an outsidedeformable structure 36, means 37 for inflating theoutside structure 36 for bringing it into an expanded state, whereby the deformable structure is in a retracted state in which the inflating means 37 are inactive. - For the production of the process for manufacturing
hollow bodies 1,prefabricated flanges 6 are used. - Continuous fibers f and coating and resistance material based on concrete or the like m are also used. This material m is able to be deposited in the liquid or pasty fluid state and then to harden quite rapidly.
- According to the process, the
mandrel 31 is placed with itsaxis 5 placed vertically or approximately vertically on a table 38 that is part of the installation. This table 38 can be made to pivot around its vertical axis by driving means such as a motorized roller. It is suitable, in line with themandrel 31, that the table has thereference 5 of the axis reference. This pivoting motion will occur subsequently. - A lower flange 6 a is placed around the
mandrel 31 toward itslower part 39. - An upper flange 6 b is placed around the
mandrel 31 towards itsupper part 40. - The two
stubs 10 of the two flanges 6 a and 6 b are located opposite one another in the direction of the transverse median plane—in this case horizontal—of themandrel 31. - The lower flange 6 a is placed on the table 38 while locking it in position relative to the latter. For this purpose, 1 a comprises—on its upper surface—locking means 41 in the position of the lower flange 6 a, working with complementary means of the flange 6 a. For example, it may be a matter of projections working with holes of the flange 6 a. The upper flange 6 b is suspended in the
upper part 40 of themandrel 31 by means of, for example,brackets 42.Radial play 43 is arranged between theoutside surface 32 of themandrel 31 and the inside surface of the flanges 6 a and 6 b. - The table 38—and therefore the
mandrel 31 and the flanges 6 a and 6 b—is then driven to rotate. By doing so, the fibers f are wound around the part of themandrel 31 that is located between the two flanges 6 a and 6 b, with the coating and resistance material m. The number of layers desired for the desired thickness, corresponding to the expected resistance performance levels, is formed. - When this stage is concluded, the thus produced
hollow body 1 is extracted from themandrel 31. Thehollow body 1 dries and hardens so as to then be able to be used for the production of astructure 2. - In the case of a
hollow body 1 having in its thickness a sandwich-type heterogeneous structure with anoutside part 28, aninside part 29, and one or more functional central part(s) 30 (FIG. 9 ), the process first comprises a stage in which the table 38 is driven to rotate, and the fibers f are wound around and on the part of themandrel 31 that is located between the two flanges 6 a and 6 b, with the coating and resistance material m by forming a certain number of layers for a desired thickness. - This stage is followed by another stage in which one or more layers of a thermal and/or soundproofing insulation material are placed on the outside surface of the previously-produced layers in order to produce the central layer(s) 30.
- This stage is followed by another stage in which the table 38 is driven to rotate, and the fibers f are wound around and on the outside surface of the layer(s) 30 of the material for thermal and/or soundproofing insulation and between the two flanges 6 a and 6 b, with the coating and resistance material m by forming a certain number of layers for a desired thickness.
- According to the embodiments, the fibers f are “single” or in a network. “Single” is defined as fibers that extend in a single direction and do not form a network.
- The process that was just described is implemented by means of an installation that first of all comprises the table 38 that was already mentioned. In addition to the locking means 41, the table 38 comprises sliding guide means of the
hollow bodies 1 that are produced, such as rails that are arranged in its upper surface. The table 38 is arranged so as to be able to accommodate the mandrel and thehollow body 1 once produced. For this purpose, in addition to a pivotingaxis 43,support rollers 44 on which tracks 45 roll from the lower surface of the table 38 are provided in one embodiment. - In contrast, the installation comprises means for winding the fibers f around the part of the
mandrel 31 that is located between the two flanges 6 a and 6 b and means for depositing the coating and resistance material m by forming the desired number of layers for the desired width. These means can comprise drums for fibers f, soaking vats, tightening means, and means for spraying or projecting the material m. In one embodiment, with these latter means, means for guiding spraying means so as to cover the entire outside surface of themandrel 31, as well as thestubs 10 of the flanges 6 a and 6 b, can be combined. - In addition, in one embodiment, the installation comprises means for maintaining a constant or approximately constant separation between the
mandrel 31 and the means for depositing the coating and resistance material m. - In the embodiment in which the
cylindrical wall 4 of thehollow body 1 comprises housing means 20 that consist of ahollow reserve 23 that is arranged in thesoffit 24, designed forelements 21 for circulation and/or for distribution of electricity or electronics, or liquid or gaseous fluids, the process is such that ahollow reserve box 46, open toward theoutside surface 32 of the mandrel and closed elsewhere, is placed and maintained in a fixed manner for the duration of the production—for example by means of a light adhesive—on theoutside surface 32 of themandrel 31, at any desired location that is determined. - As it was disclosed above, such
hollow bodies 1 make it possible to produce an infinite variety of self-supportingstructures 2. In such astructure 2, theaxis 5 of thecylindrical wall 4 is placed horizontally or approximately horizontally (FIGS. 2 , 3, and 4). The upper and lower parts of thestructure 2—or the part of thestructure 2 that is arranged using thehollow body 1—are formed by the twoparts 4 a that are horizontal or approximately horizontal that face thecylindrical wall 4. The walls of thestructure 2—or of the part ofstructure 2 that is produced using thehollow body 1—are formed by the twoparts 4 b, in particular vertical or approximately vertical, which face thecylindrical wall 4. - Such a structure comprises, according to a possible embodiment, at least two adjacent
hollow bodies 1 that are juxtaposed or superposed. - According to a possible embodiment, the two
hollow bodies 1 are juxtaposed with theircoaxial axes 5, whereby the twoflanges 6 of the twohollow bodies 1 are opposite one another and attached rigidly to one another by theattachment elements 16 that work with the attachment means 15 (FIG. 10 ). - According to another possible embodiment, the two
hollow bodies 1 are juxtaposed with theiraxes 5 that form an angle between them, for example an angle that is equal to 90° or approximately 90°, whereby twoflanges 6 of the twohollow bodies 1 are adjacent to one another and are combined rigidly with one another, directly or indirectly by means of the connecting parts. - According to a possible embodiment, the two
hollow bodies 1 are superposed with theircoaxial axes 5, whereby the twoflanges 6 of the upperhollow body 1 rest on the twoflanges 6 of the lowerhollow body 1, and whereby two flanges that are in contact are attached rigidly to one another by specific attachment means 48, such as contoured H-shaped pieces (FIG. 11 ). - According to a possible embodiment, the
structure 2 compriseselements 49 for insulation—against water, air, noise, dust, etc.—that are interposed between twoadjacent flanges 6 of two adjacenthollow bodies 1. - As indicated above, a
structure 2 can also comprise at least oneconcealment wall 3 that is provided, if necessary, with one ormore openings 3 a. Such aconcealment wall 3 is attached to aflange 6 of ahollow body 1 of thestructure 2. Such aconcealment wall 3 constitutes, according to the embodiments, an outside wall (front) or an inside wall (partition) of thestructure 2. - As disclosed above, the
structure 2 comprises a space 19 between two juxtaposed or superposed adjacenthollow bodies 1, whoseperipheral surfaces 17 of theflanges 6 are in contact. - Such a space 19 is either left empty or forms means 20 of housing for the
elements 21 for circulation and/or for distribution of electricity or electronics, or liquid or gaseous fluids, or else housing for means of thermal insulation and/or soundproofing means 22. Thus, thestructure 2 is characterized by the combination between, on the one hand, the space 19, and, on the other hand, thecylindrical wall 4 of thehollow body 1 in that it comprises or forms or helps to form the housing means 20. - As disclosed above, the

- According to one embodiment, it is possible to produce a
structure 2, with a singlehollow body 1 that has a surface on the floor that can reach on the order of 20 m2 for a body with a volume that can reach 50 m3. - The process for the production of such a self-supporting
structure 2 is now described. - According to this process, one or more
hollow bodies 1 are first produced that are brought from a situation where, for each of them, itsaxis 5 is vertical or approximately vertical—as is the case at the end of the production of thehollow body 1—to a situation where itsaxis 5 is horizontal or approximately horizontal—as is the case in thestructure 2. - If necessary, one or
