Detailed description of the invention This section describes the invention in further detail based on preferred embodiments and onthe figures.

Similar reference numbers will be used to describe similar or the same concepts throughout different embodiments of the invention.

It should be noted that features described for a specific embodiment described herein may be combined with the features of other embodiments unless the contrary is explicitly mentioned.

Features commonly known in the art will not be explicitly mentioned for the sake of focusing on the features that are specific to the invention.

For example, the construction system in accordance with the invention is evidently on the ground, even though such ground is not explicitly referenced on the figures nor referenced in the description.

Figure 1 shows a side view of a construction system 2 in accordance with a preferred embodiment of the invention.

The construction system 2 may form a wall.

The vertical direction V and the longitudinal direction L are provided for the sake of clarity.

The construction system 2 comprises several modules 4. Each module 4 may be one piece.

Each module may be formed of metal, for instance steel.

Steel may be advantageous since concrete (not represented) adherence thereon may be important.

In addition, the combination of concrete and a metal module may form a reinforced concrete.

Each or at least one module 4 may comprise polymer or another suitable material.

Recycled material is considered as well.

À separation 5 may be provided between the modules 4. The separation 5 may receive, at least partially, a door or a window.

The separation 5 may be provided between the vertical modules 4 and the horizontal modules 4. By way of example, the distance between the main directions 8 of the vertical modules 4 may be of at least 60 cm, or at least 40 cm.

This distance may correspond to the length of panels (not represented) mounted on the modules 4. Thus, the modules 4 may be used in order to form a wall of a building.

It may also be used for building a slab or an inclined roof; horizontal or inclined as well.

It may be used for the construction of a beam under a slab.

The modules 4 may be used for the foundation of a building.

For instance, a lower horizontal module 4 may be partially within a raft foundation 6. The portion of said lower horizontal module 4 may be used for supporting vertical modules 4 before concrete is poured around.

Therefore, the horizontal orientation of the lower horizontal module 4 may be used for setting the vertical orientation of the vertical modules 4 projecting above it.

Another horizontal module may be fixed on top of the vertical modules 4. The different modules 4 may be fixed to each other by fixation means (not represented). The fixation means may comprise screws, welds, locking means.

In the current illustration, only two modules 4 are represented.

However, the construction system may comprise any number of modules 4. For instance, it may comprise ten, one hundred, or more modules 4. The modules may be of different lengths.

The lengths of the modules 4 may be adapted during their manufacture in a plant, or be adjusted in situ during construction.

Thus, a single module type may be used for a whole building.

This aspect underlines the modular character of the module 4 in accordance with the invention.

| . | 8 LU101122 In the current figure, only two vertical modules 4 are represented. However, the construction system 2 may comprise more vertical modules 4, possibly identical vertical modules 4. The current figure may correspond to a pattern which is repeated in order to form a construction system 2 in accordance with the invention.

Each module 4 may comprise a main direction 8. Each main direction 8 may be along the greater dimension of the module 4. For instance, the main directions 8 of the lower horizontal module 4 and the upper horizontal module 4 may correspond to the horizontal direction. By way of illustration, the main directions 8 of the vertical modules 4 may be the vertical direction V. Each module 4 may be essentially elongated as a beam or a post. The main directions 8 may correspond to the central axes 8 of the corresponding modules 4.

: At least one module 4 may comprise bars 10. For instance, at least one module 4 comprise four bars 10. The bars 10 of a module 4 may be parallel to each other, and notably parallel to the corresponding main direction 8. The bars 10 may be corner bars 10, notably metal corner or corner steel. Each bar 10 may project all along the corresponding module with respect to the respective main direction 8. The bars 10 may be separate and distinct. They may be at distance from each other within a given module 4. They may be at distance perpendicularly to the associated main direction 8., for instance with respect to the longitudinal direction L.

At least one module 4 may comprise connecting plates 12. Within the respective module 4, the connecting plates 12 may physically connect together all the bars 10. Thus, the bars 10 are linked to each other. Then, the bars 10 and the connecting plates 12 may form a monobloc element. The bars 10 and the connecting plates 12 may form a box. As such, each module 4 may be essentially hollow. The connecting plates 12 may be distributed along the corresponding module 4. They may be arranged at regular intervals. Connecting plates 12 may form the opposite ends 14 of the corresponding module 4. Thus, connecting plates 12 may form the ends of the bars 10.

The modules 4 may comprise side apertures 16 between their bars 10. Thus, the side apertures 16 may separate the bars 10 of the corresponding module 4. Within each module 4 or in at least one module 4, the side apertures 16 may be separated by the connecting plates 12. The side apertures 16 may be distributed along the corresponding main direction 8. The side apertures 16 and the connecting plates 12 may form an alternance along the main direction 8 within at least one or each module 4.

At least one connecting plate 12 may have a central passage (not represented). At least one module 4 may comprise several central passages on as much connecting plates 12. Each connecting plate 12 of one module 4 may comprise a central passage. Optionally, each connecting plate 12 of each module 4 of the construction system 2 comprises a central passage. At least one or each central passage may allow a passage through the corresponding connecting plate 12 along the main direction 8 of the corresponding module 4.

The central passages (not represented) may be perpendicular to the side apertures 16. The central passages may be larger than the side apertures 16, notably perpendicularly and/or along the associated main directions 8. At least one or each central passage (not represented) may represent at least: the quarter, or the third, or the half, or 75%, of the area of the corresponding connecting plate 12. The connecting plates 12 may be identical within one module 4 or in each module 4. The central passages may be identical within one module 4 or within each module 4. As an example, the distance between two successive connecting plates 12 may be different than the width and/or the thickness of the corresponding module 4. For instance, the distance between two successive connecting plates 12 may be larger or smaller than the width and/or the thickness of the corresponding module 4. The thickness and the width may be measured perpendicularly to each other.

Feature defined in relation with one of the modules 4 or at least one module 4 may be applied to all the modules of the construction system 2.

Figure 2 shows a view of a construction system 2 in accordance with a preferred embodiment of the invention. The construction system 2 may form a wall. The vertical direction V is provided for the sake of clarity. A transversal direction T and a longitudinal direction L are represented. The directions L, T, V may be perpendicular to each other.

The construction system 2 in accordance with figure 2 may be substantially similar to the one in relation with figure 1. It may essentially differ due to the connection between the modules 4.

Each horizontal module 4 may be arranged between two separations 5. Similarly, each vertical module 4 may be arranged between two separation 5. The separations 5 may form recess in the construction system 2. The modules 4 may be identical.

In the current embodiment, two vertical modules 4 are connected by means of their respective ends

14. The vertical modules 4 may be in contact of each other, notably through their connecting plates 12 forming the corresponding ends 14. The main directions 8 of the two vertical modules 4 may be parallel, and their central axes 8 may be aligned.

The construction system 2 may comprise at least one or at least two horizontal modules 4 connected to the lower vertical module 4. The construction system 2 may comprise at least two horizontal modules 4 (not represented) along the longitudinal axis L, and at least two horizontal modules 4 along the transversal axis T which are also connected to the lower vertical module 4. Then, the four horizontal modules 4 may form a cross in a top view.

The connecting plates 12 of the horizontal modules 4 forming their facing ends 14 may be fixed, and in contact of the lower vertical module 4. Thus, the lower vertical module 4 may connect the horizontal modules 4 to each other, for instance as a keystone. The connecting plates 12 of thehorizontal modules may be fixed to the lower vertical module 4 and/or of the upper vertical module

4. Within at least one module, namely a first module, the distance D between two successive connecting plates 12 may be equal to the width W of a module 4 fixed thereon, namely a second module 4. Thus, the central passage of the connecting plates 12 of the second module may | communicate with the side apertures 16, possibly directly. The side apertures 16 and/or the bars 10 may be at distance from the central passages. The distance D may be measures along the main direction 8, and the width W may be measured perpendicularly to said main direction 8.

The central passages (not represented) may be perpendicular to the side apertures 16. The central passages may be larger than the side apertures 16, notably perpendicularly and/or along the associated main directions 8. At least one or each central passage (not represented) may represent | at least: the quarter, or the third, or the half, or 75%, of the area of the corresponding connecting plate 12. The connecting plates 12 may be identical within one module 4 or in each module 4. The central passages may be identical within one module 4 or within each module 4.

Consequently. a materiel injected or poured or blown in the construction system 2 may homogeneously fill empty space. Thus, a hardening material provides a better strength. A heat insulating material improves the heat insulation of the construction system 2, and may avoid thermal bridges.

In addition, the construction system 2 becomes more modular. A module 4 may be used as in a vertical or in a horizontal position. A horizontal module 4 may be fixed on top or on one side of an adjacent vertical module 4.

The connection at the ends 14 is easier, and remains compact. Thus, the connection node 18 remains hollow. This may benefit to the insulation, the strength, and eases the arrangement of tubes for electric wires or water pipes. In addition, the invention enables cost savings, and remains easy to assemble with a low skilled staff.

In one embodiment of the invention, figure 2 may correspond to a horizontal construction system, notably used for a slab, or a roof with a slope.

Figure 3 provides a schematic illustration of a portion of a construction system 2 in accordance with a preferred embodiment of the invention. The portion may correspond to a portion of figure 2. The vertical direction V, the transversal direction T and the longitudinal direction L are represented in order to ease orientation. The directions L, T, V may be perpendicular to each other.

The construction system 2 may be similar or identical to the one of figure 2, however only two modules 4 are represented and described for the sake of clarity.

Four panels 20 are represented in dotted lines. The panels 20 may be heat insulating panels. The panels 20 may comprise mineral heat insulating material, such as the material described in the document EP 2 039 664 B1. The panels 20 may be fixed to at the modules 4, for instance at least to the vertical module 4. The panels may have the same length and the same height. By way of illustration, the panels may have a length along the longitudinal direction L of 60 cm, and a height of 40 cm along the vertical direction V. The panels 20 may exhibit an interface 22, possibly a vertical interface 22, for instance between the panels 20 on the left side and the panels 20 on the right side. Similarly, a horizontal interface may be identified between the upper and the lower panels. The interface 22 may be aligned with the main direction 8, and possibly the central axis of the vertical module 4.

The construction system 2 may comprise a support 24. The support 24 may be used for connecting, at least temporarily, the panels 22. The support 24 may engage the connecting plates 12, notably between the bars 10. The support 24 may be disposed through the interface 22, notably the vertical interface. The support 24 may extend on the whole height of the module 4, notably the vertical module 4.

In spite that only one support 24 is represented, the construction system 2 may comprise several supports 24, for instance two by module 4, or two by vertical module 4.

Two connecting plates 12 of the vertical module 4 are represented. The connecting plates 12 may be parallel. These connecting plates 12 may be perpendicular to the main direction 8. The vertical spacing between these connecting plates 12 may correspond to the vertical thickness of the horizontal module 4. The upper connecting plate 12 may form the end 14 of the vertical module 4, wherein said end 14 is considered along the main direction 8 of the vertical module 4. The upper connecting plate 12 may be flush with the upper tips of the bars 10. The connecting plates 12 may be flat. They may have a first thickness T1, possibly a constant thickness.

The bars 10 may be corner bars, also known under corner steel. The bars 10 may each comprise at least two strips 26, for instance inclined strips 26. The strips 26 of at least one or each bar 10 may be inclined with respect to each other about the main direction 8 of the corresponding module 4. Therefore, the strips 26 may defines the outer ridges of the modules 4. The strips 26 may form wings.

The side apertures 16 may be delimited by the strips 26, more precisely by their opposed edges 28. At least one or each module 4 may comprise fixation orifices 30. The fixation orifices 30 may be on the bars 10, for instance on the strips 26. The fixation orifices 30 may be arranged on the four faces (only one represented by module) of the modules 4. The orifices 30 may be distributed on all the strips 26. The fixation orifices 26 may be arranged according to a pattern. The fixation orifices 30 may define rectangles, and notably squares.

Thus, the modules 4 may be fixed in different ways. For instance, the modules 4 may be fixed parallelly, or perpendicularly, by arranging their strips 26 against each other. Fixation means, such as screws, may be introduced in the fixation orifices 30 in order to lock the construction system 2. As an alternative or in addition, the modules 4 may be fixed by means of a wedge device 32. The wedge device 32 may comprise a wedge element 34 with a slight width reduction, and a wedge key 36 in abutment with the connecting plate 12 of the horizontal module 4. The wedge key 34 may comprise a slot (not represented) in which the wedge element 34 is disposed. By forcing the engagement of the latter in the slot, the modules 4 are pressed against each other, and their respective positions may be fixed.

Thus, the use of a wedge device 32 may ease the assembly of the construction system 2. In addition, the required tools are limited, as the necessary skills. Further, the construction may be progressively tightened, and easily unlocked.

In order to ease the assembly, a transversal pin 40 may be used. The transversal pin 40 may be maintained to fixation orifices 30 of a face perpendicular to the front face represented in the current figure. The transversal pin 40 may support the horizontal module 4 before the wedge device 32 or the screws are sufficiently tightened.

The connecting plate 12 of the horizontal module 4 may comprise a central passage (not represented). This central passage may communicate with a side aperture 16 on the side face 38 which receives the end 14 of the horizontal module 4. The central passage may extend on at least: a quarter, a third, or a half, or 75% of the corresponding connecting plate 12. The central passage may be centred with respect to the side aperture 16 on the side face 38, and may be greater. Thus, construction material may flow across the central passage, and across the side aperture 16 placed in front of it. À continuous passageway may be preserved. Then, the construction material may homogeneously fill the construction system, and the construction method becomes more predictable. In the current schematic illustration, a horizontal module 4 is fixed on a side of a vertical module 4. However, as an alternative, the horizontal module 4 may be arranged upside the vertical one. Figure 4 provides a schematic illustration of a construction system 2 in accordance with a preferred embodiment of the invention. The vertical direction V, the transversal direction T and the longitudinal direction L are represented. The construction system 2 may form stairs 3. In the current embodiment, three steps are represented, however the stairs 3 may comprise more steps. The construction system 2 may comprise several modules 4. The modules may be similar or identical to those as described in relation with any one of figures 1 to 3. Each module 4 may comprise connecting plates 12 and bars 10. The bars 10 may define between them side apertures

16. The connecting plates 12 may have central passages 54 which each represent at least: a quarter, a third, or a half, of the area of the corresponding connecting plate 12. The construction system 2 may comprise a lower module which is inclined with respect to the longitudinal direction L and the vertical direction V. Its main direction 8 is enclosed in a plane along the longitudinal direction L and the vertical direction V. This module 4 may be referred to as an “inclined module”. In spite that a single inclined module is represented, the construction system 2 may comprise additional, parallel and identical inclined modules. The construction system 2 may further comprise several modules 4 with main directions 8 which are along the transversal direction T. These modules 4 may be referred as “transversal modules”. The transversal modules may be received on the inclined module(s) by means of triangular adaptors 51, or angular adaptors. These adaptors 51 may be fixed to the bars 10, and notably to the fixation orifices of the inclined strips. These adaptors 51 allow that the upper faces of the transversal modules are horizontal in spite of the angle followed by the inclined module(s). As an option, after assembly, concrete or any other construction material may be applied to the construction system 2 in order to fill the modules 4 and to form the steps. As an alternative, a triangular adaptor 51 may be fixed at the ends of modules in order to form an inclined roof. Its angle may be adapted to the desire profile of the roof. Figure 5 provides a schematic illustration of a construction system 2 in accordance with a preferred embodiment of the invention. The vertical direction V, the transversal direction T and the longitudinal direction L are represented. The construction system 2 may form stairs 3. In the current embodiment, three steps are represented, however the stairs 3 may comprise more steps. The construction system 2 may comprise several modules 4. The modules may be similar or identical to those as described in relation with any one of figures 1 to 3. Each module 4 may comprise connecting plates 12 and bars 10. The bars 10 may define between them side apertures

16. The connecting plates 12 may have central passages 54 which each represent at least: a quarter, a third, or a half, of the area of the corresponding connecting plate 12. The side apertures 16 may communicate with the central passages 54 of the connecting plates 12 forming the ends 14. Thus, a filling material flow is easier. The construction system 2 may comprise a lower module which is inclined with respect to the longitudinal direction L and the vertical direction V. Its main direction 8 is contained in a plane along the longitudinal direction L and the vertical direction V. This module 4 may be referred as “inclined module”. In spite a single inclined module is represented, the construction system 2 may comprise additional and parallel inclined modules. The construction system 2 may further comprise several modules 4 with main directions 8 which are along the transversal direction T. These modules 4 may be referred as “transversal modules”.

. | 14 LU101122 The transversal modules may be fixed to a side face 38 of the inclined module. The ends 14 of the transversal modules may be fixed to the bars 10 of the inclined module. The plates 12 forming the ends 14 of the transversal modules may be fixed to the strips of the bars 10 of the inclined module

4. Therefore, the fixation orifices of bars may be fixed to the openings of the connecting plates 12 atthe ends 14. The arrangement of the fixation orifices and the orifices may be adapted such that the transversal modules exhibit horizontal upper faces. As an option, after assembly, concrete or any other construction material may be applied to the construction system 2 in order to fill the modules 4 and to form the steps.

Figure 6 provides a schematic illustration of a top view of a construction system 2 in accordance with a preferred embodiment of the invention. For the sake of clarity, only one module 4 is represented. Said module 4 may be a vertical module 4 since its main direction 8 is arranged vertically, namely along the vertical direction V. A transversal direction T and a longitudinal direction L are represented.

The construction system 2 in accordance with figure 4 may correspond to the construction system 2 described in relation with any one of figures 1 to 5, and combinations thereof.

In the current figure, only four panels 20 are represented. The two panels 20 on the upper side of figure 4 may be outer panels, intended to be outside the building. The two panels 20 on the lower side of the figure may be inner panels. They may be inside the building, for instance toward a room built by the current construction system 2. The thickness To of the outer panels 20 may be greater than the thickness Ti of the inner panels 20; for instance, at least two or three times greater.

This configuration favours the heat insulation from outside while easing the setting up of networks, for instance for electric wiring and water supply. As an option, the outer panels 20 may be covered by an outer layer 42. The outer layer 42 may form a facade, for instance made of wood, glass, metal, polymer, or any protective coating. As an option, the inner panels 20 may be covered with an inner layer 44. The inner layer 44 may comprise plaster, also known as “gypsum”. The inner panels 20 and the outer panels 20 may be spaced from each other by the module 4, and notably by an inner space 46 through which the module 4 extends vertically. Other modules (not represented) may be disposed in said inner space 46. The panels 20 may be used as formworks for filling material 48 such as concrete. Other materials, such as polyurethane foam, may be used. The filling material 48 may densify the inner space 46. The filling material 48 may fill the central passage 54. In the current figure, only a portion of the construction system 2 is filled for the sake of clarity. However, it should be understood that the filling material 48 may fill the whole free space between the panels 20, and the whole section 56. All the inclined strips 26 may be covered by the filling material, possibly over the majority of their surfaces.

As an option, a block 49 may be arranged in the inner space 46. The block 49 may be at distance from the module 4. The block 49 may extend from the inner panels 20 to the lower panels 20. The block 49 may comprise heat insulating material. It may comprise the same material as the panels

20. It may be disposed in the middle of the panels 20 between which is arranged. Then, the use of the block 49 may reduce the pressure against the panels 20 which occurs when the filling material 48 is poured or injected. In addition, the block 49 may increase the overall thermal resistance of the construction system 2 along the transversal direction T. As apparent from figure 4, two supports 24 are introduced in the vertical interfaces 22 between the panels 20. Thus, the supports 24 may prevent filling material leakages. In addition, the supports 24 may comprise retention surfaces 50 engaging the edges of the panels 20 in order to link them to the module 4, and possibly to the stacked connecting plates 12 (only one represented). Their widths are adapted to the thicknesses Ti and To of the panels. The supports 24 may comprise resilient portions engaging at least one panel 20. The resilient portions may be resilient branches 52. The retention surfaces 50 may be formed on the resilient branches 52. The resilient aspect allows an easier positioning of the panels 20. It also improves the leak tight character. The use of resilient branches 52 allows to control the width of a gap 53 between said branches. The connecting plate 12 may have a rectangle shape. Its outline 55 may describe a rectangle. The connecting plate 12 may comprise a central passage 54, for instance rectangular too. The central passage 54 may be along the main direction 8. The area of the connecting plate 12 may be defined by its outline 55, which in the current embodiment, forms a rectangle. The area of the connecting plate 12 may be calculated by multiplication of the outer dimensions along the transversal direction T and the longitudinal direction L. Along the transversal direction T, the width of central passage 54 may represent at least the half of the width of the connecting plate 12. Along the longitudinal direction L, the length of central passage 54 may represent at least the half of the length of the connecting plate 12. The area of the central passage 54 may represent at least: 10%, or 25% or 33%, or 50% or 75% of the area of the connecting plate 12. A central passage 54 representing at least 25% of the connecting plate 12 generally corresponds to asituation where the central passage 54 extends on the half of the width and of the length of the connecting plate 12. Consequently, a wide passage is provided for the filling material 48 which simply reaches the bottom of the module 4. The at least 25% feature, corresponding to the at least one quarter feature, ensures good flow conditions. The module 4 may comprises a section 56. The section 56 may be defined perpendicularly to the main direction 8. The section 56 may be an inner section 56 of the module 4. The inner section 56 may define an inner passage between the bars 10. The section 56 may be the section 56 of the connecting plate 12. The section 56 may be inscribed in the bars 10; and/or between the bars 10.

The sides of the section 56 may be drawn by the strips 26. The section 56 may be a rectangle, with corners matting with the bars 10. By way of example, the section 56 may match the outline 55. The { central passage 54 may extend on at least: 10%, or 25% or 33%, or 50% or 75% of the section 56. This geometry fosters a building material flow, and guaranties a required filling throughout the construction system 2. The contact surface between the filling material 48 and the module 4 steps up. The module 4 may comprise fixation holes 58, for instance at least four fixation holes 58. The fixation holes 58 may be rectangular. The fixation holes 58 may be arranged between the bars 10, | notably a distance from the strips 26. The fixation holes 58 may be centred on the sides of the connecting plate 12. The fixation holes 58 may be formed on the connecting plate 12, and may cross it along the main direction 8. The supports 24 may be fixed to the fixation holes 58. The connecting plate 12 may comprise a frame 60, for instance a rectangular frame. The frame 60 may delimit the central passage 54. The frame 60 may encircle the central passage 54. The frame 60 may comprise four segments extending from one bar 10 to another bar 10. The fixation holes 58 may be formed on the frame 60. The area of the frame 60 may represent at most: 50%, or 40%, or 30%, or 20%, of the area of the connecting plate 12. In the current embodiment, the connecting plate 12 forms a rectangle, however it could form a square or a parallelogram. Other shapes are considered. Other numbers of sides and corners are considered. Only one module 4 is mentioned. However, the current teaching may apply to all the modules 4 of the construction system 2. Similarly, only one connecting plate 12 is apparent. However, the current teaching may apply to all the connecting plate of the represented module, and possibly to all the modules of the construction system 2.

Figure 7 provides a schematic illustration of a construction system 2 with a support 24 in accordance with a preferred embodiment of the invention. The vertical direction V, the transversal direction T and the longitudinal direction L are represented. In the current embodiment the vertical direction V may correspond to the main direction 8 of a module on which the support 24 is hanged up. The construction system 2 in accordance with the current embodiment may be similar or identical to the one as described in relation with any one of figures 1 to 6. It may differ in that the construction system exhibits a body 62, which may replace an element, or which may be added to other elements. The support 24 may comprise a body 62. The body 62 may be elongated along the main direction

8. The body 62 may be segmented vertically. It may be fixed to the resilient branches 52 of the support 24. For this purpose, fixation means 64 such as screws may be used. The body 62 may

| 17 LU101122 comprise wood, or timber. The body 62 may increase the width of the interface 22 between the panels 20. The panels 20 may be in contact of the body 62 along the longitudinal direction L in order to set the distance between the panels 20. Consequently, the positioning of the panels 20 is more accurate along the whole height of the module 4.

The body 62 may receive a layer 43, such as inner layer or an outer layer as described in relation with figure 4. The layer 43 may be fixed to the body 62; for instance: by screws, glue, hooks or any equivalent means. The layer 43 may comprise retention surfaces 50 engaging the panels 20. Thus, other assembly solutions are provided. In addition, the layer 43 may be used to strengthen the panels 20, and may be used to maintain them before concrete; or any other construction material; is poured, or injected, or blown, in the inner space 46. The support 24 may comprise a main portion 66, for instance from which the resilient branches 52 project. The main portion 66 may be in contact of the connecting plate 12. The main portion 66 may be on the frame 60. The support 24 may comprise a protruding portion 68. The protruding portion 68 may protrude from the main portion, for instance downward. The protruding portion 68 may form a hook. The protruding portion 68 may cross the connecting plate 12, for instance through the fixation hole 58. Thus, the support 24 may be linked and maintained to the module 4. As an option, the support 24 may comprise as much protruding portions 68 as connecting plates 12. Figure 8 provides a schematic illustration of a construction system 2 with a support 24 in accordance with a preferred embodiment of the invention. The vertical direction V, the transversal direction T and the longitudinal direction L are represented. In the current embodiment the vertical direction V may correspond to the main direction 8 of a module on which the support 24 is hanged up. The construction system 2 in accordance with the current embodiment may be similar to the one as described in relation with any one of figures 1 to 7. It may differ in that the construction system exhibits a body 62, which may replace an element, or which may be added to other elements. The support 24 may comprise a main portion 66, for instance from which the resilient branches 52 project. The main portion 66 may be in contact of the connecting plate 12 of the module 4. The main portion 66 may be on the frame 60. The support 24 may comprise a protruding portion 68. The protruding portion 68 may protrude from the main portion, for instance downward. The protruding portion 68 may form a hook. The protruding portion 68 may cross the connecting plate 12, for instance through the fixation hole 58. The support 24 may comprise a body 62. The body 62 may be elongated along the main direction

8. The body may be segmented vertically. The support 24 may receive temporary holders 65. For this purpose, fixation means 64 such as screws may be used. The temporary holders 65 may be resilient.

. 18 LU101122 The fixation means 64 may be reversible fixation means in order to remove the temporary holders 65 after application of filling material (not represented) in the inner space 46. The body 62 may comprise wood, or timber. The body 62 may increase the width of the interface 22 between the panels 20. Further, temporary links 67 may be used to temporary maintain the panels 20. The temporary links 67, for instance of wood, may be fixed to the temporary holders 65 by means of fixation means 64. The temporary links 67 may be horizontal bars, with a height reduced with respect to the height of the panels 20. The temporary links 67 may project over the whole longitudinal length of the corresponding panel, and may be fixed to another temporary holder 65 or said corresponding panel.

Thus, the panels 20 may be mounted after fixation of the temporary links 67. Thus, inner panels and outer panels may each be mounted from inside, which confirms that outer scaffolding becomes unnecessary in the context of the invention. Then, the invention offers costs savings and an improved safety.

After hardening of a filling material, the fixation means 64, the temporary holders 65 and the temporary links 67 may be removed, and stored until another use at another location of the construction system 2, for instance at an upper location. Then, waste is reduced through the invention.

In the current description, the support 24 is described as a vertical support 24. However, it may be deduced from the current description that the support may also be used as a horizontal support, notably below the panels 20.

Figure 9 provides a schematic illustration of a top view of a construction system 2 in accordance with a preferred embodiment of the invention. For the sake of clarity, only one module 4 is represented. Said module 4 may be a vertical module 4 since its main direction 8 is arranged vertically, namely along the vertical direction V. A transversal direction T and a longitudinal direction L are represented.

The construction system 2 in accordance with the current embodiment may be similar to the construction system 2 as described in relation with any one of figures 1 to 8, and combinations thereof.

Inthe current figure, only four panels 20 are represented. These four panels 20 may be main panels

20. The two panels 20 on the upper side of figure 4 may be outer panels, intended to be outside of the building. The two panels 20 on the lower side of the figure may be inner panels. They may be inside the building, for instance toward a room built by the current construction system 2.

On the left side, a side panel 21 may project from an inner panel 20 to an outer panel 20. It may close the left side of the inner space 46. It may be used as formwork against which filling material 48 may be poured, injected, or blown. The side panel 21 may be received by the body 62 of the left support 24 which is maintained in the left fixation hole 58. It may be at distance from the module 4.

It may be used for fixing a window or a door as well. The window or a door may be screwed in the body 62 through the side panel 21. The interface 22 between the outer panels 20 may be filled by a transversal panel 23. The transversal panel 23 may be in contact of the outer panels 20 at each side of the interface 22. The transversal panel 23 may be in contact of the body 62 of the support 24 on the upper side of the figure. Thus, it may close a thermal bridge. The transversal panel 23 may replace the fixation means, the temporary holders and the temporary links after removal. As an option, the outer panels 20 and the transversal panel 23 may be covered by an outer layer 42. The outer layer 42 may form a facade, for instance made of wood, glass, metal, polymer, or any protective coating. As an option, the inner panels 20 may be covered with an inner layer 44. The inner layer 44 may | comprise plaster, also known as “gypsum”.

The side panel 21 may comprise the same material as the main panels 20, as an option the transversal panel 23 too. The side panel 21 may be covered by the outer layer 42 and/or the inner layer 44.

The inner panels 20 and the outer panels 20 may be spaced from each other by the module 4, and notably by an inner space 46 through which the module 4 extends vertically. Other modules (not represented) may be disposed in said inner space 46. The panels 20 may be used as formworks for filling material 48 such as concrete. Other materials, such as polyurethane foam, may be used. The filling material 48 may densify the inner space 46. The filling material 48 may fill the central passage 54. In the current figure, only a portion of the construction system 2 is filled for the sake of clarity. However, it should be understood that the filling material 48 may fill the whole free space between the panels 20. It may be in contact of the bars 10, and may cover at least one or the two faces of each inclined strip 26.

The construction system 2 may comprise a block, notably as described in relation with figure 6. The block may be maintained in position by a support (not represented) which is fixed to the fixation hole 58 on right side of the figure. This right support may be symmetrical to the support 24 on the left which receives the side panel 21. Thus, the right support may maintain the block. The block may be an insulating block received in the inner space 46 between the outer panels 20 and the inner panels 20.

Figure 10 provides a schematic illustration of a connecting plates 12 of a module 4 in accordance with a preferred embodiment of the invention. The module 4 in accordance with figure 10 may be identical or similar to the module 4 described in relation with any one of figures 1 to 9, and combinations thereof.

The connecting plate 12 may present a rectangle profile. Its outline 55 may describe a rectangle.

The connecting plate 12 may comprise a central passage 54, for instance rectangular too.

The central passage 54 may be centred on the central axis 8 of the module 4 and/or of the connecting plate 12. The centre of the central passage 54 may be on the central axis 8. The area of the central passage 54 may represent at least: 10%, or 25% or 33%, or 50% or 75% of the area of the connecting plate 12. The area of the connecting plate 12 may be the area within the outline 55, which in the current embodiment, forms a rectangle.

The area of the connecting plate 12 may be calculated by multiplication of its outer dimensions along the transversal direction T and the longitudinal direction L.

The connecting plate 12 may exhibit a first dimension along the longitudinal direction L, notably a length; and a second dimension along the transversal direction T, notably a width.

The first dimension may be larger than the second direction.

Consequently, the module 4 may set different spacings between the panels (not represented) it receives.

As an example, the length may be of about 0,2 m, and the width may be of about 0,15 m.

The module 4 may comprises a section 56. The section 56 may be an inner section 56. The inner section 56 may be defined perpendicularly to the main direction 8. The inner section 56 may be the section 56 of the connecting plate 12. The inner section 56 may be inscribed in the bars 10; and/or between the bars 10. The sides of the inner section 56 may be drawn by the strips 26 of the bars 10. The inner section 56 may be a rectangle with corners at the inner nooks 57 of the bars 10. By way of example, the section 56 may correspond to the outline 55. The central passage 54 may extend on at least: 10%, or 25% or 33%, or 50% or 75% of the section 56. This geometry fosters a building material flow, and guaranties a required filling throughout the construction system 2. The module 4 may comprise fixation holes 58, for instance at least four fixation holes 58. The fixation holes 58 may be arranged between the strips 26, notably a distance from the edges 28. The fixation holes 58 may be centred on the sides of the frame 60. The fixation holes 58 may be formed on the frame 60, and may cross it along the main direction 8. Each bar 10, and possibly each strip 26, may exhibit a fixation orifice 30; possibly between two successive connecting plates 12. The frame 60 may be rectangular.

The frame 60 may form a closed loop.

The frame 60 may touch the central passage 54. The frame 60 may encircle the central passage 54. The frame 60 may comprise four ribbons 61 extending from one strip 26 to another strip 26. The fixation holes 58 may be formed on the frame 60. The surface of the frame 60 may represent at most: 50%, or 40%, or 30%, of the area of the connecting plate 12. It may be understood that the area of the connecting plate 12 is equal to the addition of the surfaces of the central passage 54 and of the frame 60. The construction system 2 may comprise at least one positioning notch 70. The positioning notches 70 may be formed on the connecting plate 12, for instance at the frame 60. The positioning notches 70 may form recesses in the ribbons 61. The positioning notches 70 may be part of the centralpassage 54. They may be used for positioning ridged bars 72, or rebars. These ridged bars 72 may be used for reinforced concrete.

The area of the frame 60 may be smaller than the area of the central passage 54. The central passage 54 may be greater than each or at least one side aperture 16.

The strips 26 may comprise longitudinal strips along the longitudinal direction L, and transversal strips along the transversal direction T. The strips 26 of the bars 10 may be perpendicular, At least one or each bar may comprise a transversal strip and a longitudinal strip perpendicular to the transversal strips. Thus, all the strips 26 of the module 4 may form two sets of parallel strips: strips parallel to the transversal direction T, and strips parallel to the longitudinal direction L.

The frame 60 may exhibit a first width W1. The first width W1 may be the width of the ribbons W1. The transversal strips may exhibit a second width W2 measured along the transversal direction T. The longitudinal strips may exhibit a third width W3 measured along the longitudinal direction L. The third width W3 may be greater than the second width W2. The first width W 1 may be smaller than the third width W3 and/or the second width W2. The first width W1 may represent at least the half the second width W2, notably in order to preserve stiffness of the connecting plate 12. The transversal strips and the longitudinal strip may have a second thickness T2. The second thickness T2 may be smaller than the first thickness T1 (not represented) of the connecting plate. It may be considered that the stiffness of the connecting plate 12 is rather provided by its first thickness than by the first width W1. Thus, the overall weight may be reduced, and the costs as well. Openings 74 may be formed on the connecting plate 12. The openings 74 may be distributed on the ribbons 61 of the frame 60. These openings 74 may be used for introduction of ridged bars 72. They may be used for fixing another module 4, for instance by means of fixation orifices 30 of another module 4. The spacing between two fixation orifices 30 of one side of the module 4 may be equal to the spacing between two other fixation orifices 30 on and adjacent side, and/or equal to the spacing of two openings 74. This feature allows more assembly configurations, and eases on site assembly. In the current embodiment, the connecting plate 12 forms a rectangle, however it could form a square or a parallelogram. Other shapes are considered. Other numbers of sides and/or corners are considered. Only one module 4 is mentioned. However, the current teaching may apply to all the modules 4 of the construction system 2. Similarly, only one connecting plate 12 is apparent. However, the current teaching may apply to all the connecting plate of the represented module, and possibly to all the modules of the construction system 2.

Figure 11 provides a schematic illustration of a connecting plates 12 of a module 4 in accordance with a preferred embodiment of the invention. The module 4 in accordance with figure 7 may be identical or similar to the module 4 described in relation with any one of figures | to 6, and combinations thereof. It substantially differs on the shape of the connecting plate 12 and on the number of strips 26 pro bar 10. The module 4 may include an inner section 56. The inner section 56 may be defined perpendicularly to the main direction 8. The inner section 56 may be inscribed in the bars 10; and/or between the bars 10. The sides of the section 56 may be drawn by the outer strips 26. The section 56 may be a rectangle, with corners matting with the outermost inner corners of the bas 10.

The central passage 54 may extend on at least: 10%, or 25% or 33%, or 50% or 75% of the section

56.

The connecting plate 12 may have a circular shape. Its outline 55 may describe a circle or an ellipse. The connecting plate 12 may comprise a central passage 54, for instance circular too. The area of the central passage 54 may represent at least: 10%, or 25% or 33%, or 50% or 75% of the area of the connecting plate 12. The area of the connecting plate 12 may be the area inside the outline 55. The connecting plate 12 may project outside the bars 10. The outline 55 may cross the section 56, and may cross the side apertures 16.

The connecting plate 12 may form a ring. The frame 60 may have an annular shape around the central axis 8. The ribbon 61 may define a loop around the central passage 54.

The bars 10 may be identical and/or symmetric. The bars 10 may have “U” shapes, or “U” sections. At least one or each bar 10 comprises at least three strips 26. Said strips may comprise a transversal strip, and two longitudinal strips. The longitudinal strips may be parallel. The longitudinal strips may comprise an inner longitudinal strip toward the central axis 8, and an outer longitudinal strip which is wider than the inner longitudinal strip. The longitudinal strips may be on the same face of the transversal strip, or may alternatively project in opposite directions. The longitudinal strips may be fixed to the connecting plate 12, for instance by welding. The inner longitudinal strips provide an additional surface adhering to construction material, and increase the overall strength.

The module 4 may comprise at least one outer passage 76, possibly several outer passages 76. The outer passages 76 may be along the main direction 8. The module 4 may comprise at least one outer passage 76 between two bars 10, and/or in the bars 10. The outer passages 76 may be around the central passage 54. The central passage 54 may comprise a surface which is greater than any surface of the outer passages 76, or of the combination of the surfaces of the outer passages 76. Then, the central passage 54 may be the main passage of the module 4 and/or of the connecting plate 12.

The frame 60 may exhibit first thickness and a first width W1. The first width W1 may be the width of the ribbon W1. The transversal strips may exhibit a second width W2 measured along the longitudinal direction L. The outer longitudinal strips may exhibit a third width W3 measuredalong the transversal direction T. The inner longitudinal strips may exhibit a fourth width W4 measured along the transversal direction T. The third width W3 may be greater than the second width W2 and the fourth width W4. The first width W1 may be smaller than the third width W3 and/or the second width W2, and/or the fourth width W4.

The module 4 may comprise fixation holes 58, for instance at least four fixation holes 58. The fixation holes 58 may be arranged between the bars 10, notably a distance from the strips 26. The fixation holes 58 may be formed through the ribbon 61. The fixation holes 58 may be arranged between the central passage 54 and the outline 55.

At least one fixation hole 58 may be outside the outline 55.

As an option, the transversal sides of the frame 60 may be flat in order to be aligned with the outer longitudinal strips. Then the outline may comprise straight lines. The positions of the fixation holes 58 may be adapted accordingly. The invention considers a construction system where all the embodiments of figures 1 to 11 are combined together, for instance in a same building.

Figure 12 provides a schematic illustration of a diagram representing a heat insulation wall construction method. The module and/or the construction system used in the method may correspond to the one described in relation with any one of figures 1 to 11. The method may comprise the following steps, notably in the following order: s positioning 100 the module, then s mounting 102 the heat insulating panels at two transversally opposite or two longitudinally opposite sides of the module, then ® pouring or injecting 106 the filling material between the heat isolation plates.

Step mounting 102 may comprise at least two sub-steps. It may comprise a sub-step mounting the outer panel 108, then a sub-step mounting the inner panel 110. The panels may be mounted progressively. All steps and sub-steps may be carried out without scaffolding outside the building. During step pouring or injecting 106, the filling material hardens in the module and in contact of the panels, the filling material notably being concrete. Vibrations may be used in order to increase the homogeneity of the filling material.

The heat insulation wall construction method may comprise a step positioning 104 tubes before step pouring or injecting 106, and possibly before or during step mounting 102. As an alternative, step positioning 104 may be carried out between sub-step mounting the outer panel 108 and the sub-step mounting the inner panel 110. Then, the tubes may be mounted before the filling material is used. They are placed before the filling material hardens, which eases preparative works.

It should be understood that the detailed description of specific preferred embodiments is given by way of illustration only, since various changes and modifications within the scope of the invention will be apparent to the person skilled in the art.
