- FIGURES 1 & 2 we can see a basic element 10 constituting a modular shuttering mold produced from a rectangular membrane 12 of perimeter A, B, C, D, A, each of the angles is hollowed out so as to obtain a generally cruciform shape as expressed, by continuous lines.
- the membrane 12 now comprises two flat terminalms 14 and two lateral edges 16, as well as a recess in a quantum of circle 18 intended to allow the change of curvature necessary for the flat terminations 14 to take their inclination from the meeting point 19 between the flat terminations 14 and loteral leaps 16.
- the membrane 12 should be flexible, air and water impermeable as well as resistant to ultraviolet radiation. The resistance to abrasion and tearing are all necessary characteristics, as well as the ability of the material of the membrane to allow assemblies using common techniques such as high-frequency welding, or conventional thermal , sewing, or bonding, using adhesives and glues.
- FIGURE 1 illustrates by means of a dotted line
- FIGURE 2 illustrates a basic element in the shape it follows by becoming a constituent element of the modular shuttering mold.
- FIGURE 3 schematically illustrates a series of basic elements 10 assembled along the dotted line as shown in FIGURES 1 & 2 previously cited.
- the series of modular basic elements 10 can be used to constitute a wall or face 20 of a parallelepiped as described in FIG. 4.
- the grooved appearance of the wall formed by assembling the basic modular elements 10 may not correspond to the desired pattern for a wall molded on this wall.
- FIGURE 4 there is seen a supply pipe or sleeve 22 intended for supplying pressurized air and which is inserted through one of the walls 20 in a conventional manner.
- Each wall 20 is attached to the wall which is adjacent to it by assembling and welding the flat terminations 14 with the sides of the walls formed by the flat end termination 17, so as to form the edges.
- the flat terminations 14 adjacent to a side border 17 can be joined to one another.
- the edge of the wall 17 can be cut and reduced along the edges, as indicated at 17 in FIGURE 3, so as to avoid an excess of material and constitute the edge of the panallelepiped.
- the arrows indicate the wall portions and the direction they must take to be joined.
- Pieces in the form of spherical caps 24 made of the same material, at the upper and lower angles, at the places where the walls join three to three, are placed so as to close the remaining openings of the mold, shuttering so that it could be inflated.
- the axonometric view of FIG.5 illustrates the problem of the bending of the walls of the parallelepiped when the shuttering mold is inflated to a pressure allowing it to supponten the application of material that can be matured in the plastic state. The dimensional integrity of such a structure is then hung and its curvature can no longer be architecturally acceptable to allow its use.
- the present invention solves the problem and makes it possible to obtain structures of standardized shapes whose walls are assembled according to the orthogonal mode, also allowing combinations with curved and domed shafts in part or in whole, at will.
- FIGURE 6 illustrates a part of the system allowing the dimensional integrity of the module to be maintained.
- the longitudinal flat edges 16 of the base elements 10 joined two by two in accordance with FIGURE 3 are extended from the upper wall to the opposite bottom wall thus forming bumps 26 allowing the dimensional stability to be maintained between two walls 20 opposite, as indicated.
- the tensioner network 26 can be constituted by strips made) in the material (of the membrane) separated from each other, welded or sewn or glued, etc.) with longitudinal wound edges 16 respectively opposite, or constituted by an extension partial or total of said flat edges, assembled to the nespectively opposite flat bond or a, its extension.
- FIGURE 7 illustrates, by way of examples, sheets 30 in place of separate strips. In the case of this illustration, as the module is presented, the system is oriented vertically, but does not necessarily have to be.
- FIGURE 8 is a view, partially in section, of another case of figure using the connections 26 binders each, of the walls 20 at its respective opposite so as to obtain the same result as in the case presented in FIG. 7 the shuttering mold being thus stabilized dimensionnetlemeni in all the selections in which a bulging effect would be feared.
- FIG.9a A series of basic modular elements 10 can be assembled as illustrated in FIG.3;
- the modular base unit can advantageously be modified so as to eliminate part of the terminal terminals 14, situated beyond the curved portion 18, thus obtaining straight jumps 15 parallel to the jumps of the flat lateral joints.
- the side of the membrane 40 will meet the shortened part extending by the appropriate distance until joining the new hop 15 of the flat termination, so as to allow the junction of the sides to form the parallelepiped.
- flat side 17 can be adjusted so as to allow the membrane 40 to extend the necessary length so as to permeitre the assembly along the edges.
- the assembly of the spherical caps 24 at the location of the corresponding openings, as illustrated in FIG. 4, will complete the procedure of the external assemblies.
- the wall 20 will be assembled to the membrane 40 along the line of tangency between the membrane and the basic modular element 10 banding the wall 20, and along the new edges 15 of the shortened flat terminations 14.
- the result obtained is then an element in the form of a groove whose bottom is substantially flattened between the flat lateral edges 16.
- the outer envelope or member 40 will now have a flat and smooth surface on which can be applied curable materials used in the plastic state.
- bans Figure 9b are proposed a method and a device intended not only to allow the obtaining of a flat surface not grooved which can supponté an application of curable material still in the plastic state, but also which avoids rounding to all the parties.
- the angle elements at right angles 64 are used at the base (one of them is shown in operational situation and the other is positioned pinned to the foundation or to the edge of the slab, against the modular shuttering mold ) and along the vertical edges.
- These braces 64 can be made of metal or plastic and can also be designed to constitute an integral part of the structure or be removable so as to re-use them.
- the membrane 40 is made with a puppet of an extensible material such as a knitted fabric, thus allowing the basic fluted elements to retain their natural rounded shape.
- the junction jumps of two adjacent membranes 40 along an edge are assembled so as to sink a sheath 53 comprising notches, on request, in order to allow free access to the angles 64, good FIG. 9b the assembly consisting of basic modular elements 10 is assembled to the envelope or sheet 40 along the line of tangency located between the membnane 40 and the connected basic element forming an angle of the wall, at 41 .
- FIGURE 10 is presented a shuttering module connespondant a chamber 50 it can be used alone or in combination with other shuttering modules 70 so as to allow by combining them the realization of a construction with several rooms, it can also be combined vertically in the case of multi-storey constructions.
- the shuttering module of a chamber 50 is fixed in a conventional manner to a slab or a foundation prepared in advance 51, the latter is inflated by a known conventional method such as the sleeve 22 supporting the module 50 to a source of pressurized air 23 until it is in a partial inflation situation. Partial inflation makes it easier to install certain panels.
- the coffining module is then ready to receive decks, windows, electrical and plumbing accessories, for air conditioning, etc. ..
- a ceiling lamp 58 and a Skydome 60 are included can also integrate a series of panels 62, having acoustic properties, to which the accessories can be fixed.
- corner angles or moldings 64 in plastic, wood or metal can be arranged on both the upper and lower edges. walls and can also be used as internal or external corner brackets of a chamber constructed by means of said modular formwork mold.
- angles 64 are not necessary or useful for the structure of the building, they can be removable and reusable.
- the vertical corner brackets are shown inserted in a sheath 53 constituting the modular shuttering mold.
- the corner angles rest along the diagonals of the parallelogram, the base or the ceiling so as to allow storage and handling up to the site, for inflation. may be part, integral of the foundation or the slab on which the modular shuttering mold, still deflated, must be erected.
- corner angles are provided with perforations so as to allow the use of all kinds of various clips and tensioners necessary to secure in the desired position the accessories intended to be incorporated into the wall to be produced.
- wall panels, plaster panels, or any textile material may be used so as to allow an interior finish of the wall to be obtained, once consinuction has been achieved.
- the accessories and elements shown in the illustration can be fixed directly to the formwork module using removable adhesive tape.
- the WC, kitchen elements, shower cubicles, etc. can be made up of custom-made prefabricated units and applied to the modular shuttering mold of a room or building, so as to allow their incorporation in construction, in the case where the exterior shape thus added to the planar base wall is of aesthetic, and / or architectural interest.
- FIGURE 11 shows the modular shuttering mold shown at different stages of construction.
- the construction of the exterior walls illustrates the possibility of using plasterboard 66, lattice or bar reinforcements 72, concrete 74, thermal insulation material 76 (expended on site, or in panels) and exterior finishing material 78. Additional stages can be added, as indicated in the silhouette.
- Figures 12-14 show different forms of modular shuttering molds 80 using the concepts of this invention.
- Figures 12 and 13 show structures with a mansard roof and the other a two-pitched roof, while Figure 14 shows a structure with a triangular base. In the case of buildings whose base shape differs from the rectangle or square, there are two methods to consider. The first consists in producing a basic unit module as presented in FIGs.
- the curved roof implies that the vertical strips are of variable lengths so as to force the membrane of the roof of the formwork module to conform to the desired curvature. If the face 80 of the module must be curved or curved, the horizontal connection will also be variable according to the desired curve.
- an alternative to the various modular formwork units described in F1G.11 to 13 and resulting from the present invention consists in separating the composite modules, for example in parallelepipeds which can be joined together so as to form structures with polygonal faces of variable dimensions and triangular modules, domes, pyramids, with curved walls, or unit combinations, when this has economic advantages, etc., said structures being able to be added to the main module so as to produce a composite module corresponding to the different desired architectural forms.
- the modular shuttering mold object of the present invention is brought in the inflated state on the site which has previously been prepared by pouring foundations or a slab by the appropriate methods, which are not part of the present invention, so to attach the modular formwork mold to it.
- a pressurized air source is connected to the interior of the shuttering module, and the pressure is adjusted to allow the exchange corresponding to the required quantity of material to be applied to the module to be collected.
- Modules corresponding to other types of elements such as, double slope roofs, curved roofs or walls, sanitary elements, shower cubicles, storage elements etc. .. could also be installed on the base and / or on the module, if necessary, the pre-frames corresponding to the openings connecting two modules are inserted between them, plated with each of them, and finally all the necessary elements can be bonded to adhesive or attached by appropriate means on the formwork, modular.
- a curable building material but still in the plastic state, of the trade, is applied to make the exterior walls and the roof in the case of single-level buildings, and the ceiling constituting the upper floor. in the case of multi-storey buildings, etc. ..
- the common wall is advantageously produced between the two modular shuttering molds, once the completion of the facade walls by application of - hardenable materials used, in a plastic state.
- a junction element can be used to support said hardening materials at the junction of the two formwork molds. It is thus possible to make constructions that meet the criteria of conventional architecture, and where appropriate equipped with parapets, domes sections and other current forms not easily achievable by the usual methods of construction other than that of using a modular inflatable formwork.
- the flexibility of design resulting from the present invention also allows the realization of buildings with polygonal bases as well as polyhedra etc ...
