Description

Title of the invention: Construction element Technical field

[0001] The present invention relates to a building block as well as a building element comprising several building blocks and an assembly allowing the composition of a wall using the blocks in question. It finds particularly advantageous application in the field of the building and public works industry, in particular for the construction of low walls, retaining walls, noise barriers or the like. STATE OF THE ART

[0002] In the field of the building industry and more particularly of building blocks, it is necessary to develop building blocks which can form solid wall panels, which can be easily constructed, have the desired properties and in particular the desired aesthetic appearance.

[0003] In order to best achieve these different objectives, a technical solution has been proposed in document FR 2936261 A1. This technical solution is based on the development of a construction element that can be superimposed on other similar construction elements and comprising at the ends of the construction element a connecting wall provided with projections whose role is to disperse the acoustic waves reaching the construction element. Also, this technical solution has the particularity of forming a construction element comprising two construction blocks, thus allowing easier construction.

[0004] However, this type of solution has drawbacks, notably the fact that it is limited in terms of the construction possibilities it allows.

[0005] An object of the present invention is therefore to propose a construction element making it possible to overcome at least part of the drawback cited.

[0006] Other objects, features and advantages of the present invention will become apparent from a consideration of the following description and accompanying drawings. It is understood that other advantages may be incorporated. SUMMARY

[0007] To achieve this objective, according to one embodiment, a construction element is provided comprising a plurality of construction blocks:

[0008] characterized in that the plurality of blocks comprises a first building block, a second building block, a third building block and a fourth building block which are integral with each other but separable at a longitudinal connection zone and a transverse connection zone,

[0009] and in that the longitudinal connection zone and the transverse connection zone are perpendicular to each other.

[0010] Thus, the fact that the construction element comprises four construction blocks which can be secured to each other (so as to form a quadrilateral whose sides are formed by two adjacent construction blocks) or isolated from the others by having detached them (individually or in groups of two or three) makes it possible to facilitate the construction of the wall walls (made by superimposing construction elements) by making the construction stages more flexible according to the constraints encountered (need for rapid construction, need for reduced weight to handle). Indeed, this invention makes it possible to position, in a single step, either one construction block, or two construction blocks (extending in the longitudinal direction or in the transverse direction), or three construction blocks, or four construction blocks.This invention also makes it possible to obtain a building element having a greater width and length as a result of positioning two building blocks in the longitudinal direction (defined by the direction of extension of the longitudinal connection area) and in the transverse direction (defined by the direction of extension of the transverse connection area).

[0011] Another aspect relates to a wall composition assembly comprising a plurality of building elements, the plurality of building elements being superimposed on each other. BRIEF DESCRIPTION OF THE FIGURES

[0020] Before beginning a detailed review of embodiments of the invention, optional features which may possibly be used in combination or alternatively are set out below:

[0021] According to one example, - the longitudinal connection zone comprises a first longitudinal connection zone and a second longitudinal connection zone, - the cross-connection zone comprises a first cross-connection zone and a second cross-connection zone, - the first building block comprises a first longitudinal wall, a first transverse wall, a first additional longitudinal wall and a first additional transverse wall, - the second building block comprises a second longitudinal wall, a second transverse wall, an additional second longitudinal wall and a second additional transverse wall, - the third building block comprises a third longitudinal wall, a third transverse wall, an additional third longitudinal wall and an additional third transverse wall, - the fourth building block comprises a fourth longitudinal wall, a fourth transverse wall, an additional fourth longitudinal wall and an additional fourth transverse wall, - the first additional longitudinal wall is integral but separable from the second longitudinal wall at the level of the first transverse connection zone, - the second additional transverse wall is integral but separable from the third transverse wall at the level of the first longitudinal connection zone, - the third longitudinal wall is integral but separable from the fourth additional longitudinal wall at the level of the second transverse connection zone, - the fourth transverse wall is integral but separable from the first additional transverse wall at the level of the second longitudinal connection zone.

[0022] According to one example, the first longitudinal connection zone, the second longitudinal connection zone, the first transverse connection zone and the second transverse connection zone are discontinuous.

[0023] Thus, due to this configuration and more precisely due to the discontinuity of all the bonding zones, the dissociation between the different building blocks can be achieved easily, that is to say without requiring the application of a significant force at the bonding zones. Indeed, due to the discontinuity of the bonding zones, a concentration of stresses is present only at the bonding zones, thus making it possible to obtain an easier rupture of the bonding zones.

[0024] According to an example: - the first longitudinal connecting zone comprises first longitudinal rectilinear junctions, connecting on one side to the second additional transverse wall and on the other side to the third transverse wall and extending along a height dimension of said walls, - the second longitudinal connecting zone comprises second longitudinal rectilinear junctions connecting on one side to the fourth transverse wall and on the other side to the first additional transverse wall and extending along a height dimension of said walls, - the first transverse connection zone comprises first transverse rectilinear junctions connecting on one side to the first additional longitudinal wall and on the other side to the second longitudinal wall and extending along a height dimension of said walls, - the second transverse connection zone comprises second transverse rectilinear junctions connecting on one side to the third longitudinal wall and on the other side to the fourth additional longitudinal wall and extending along a height dimension of said walls.

[0025] Thus, the configuration of all the connection zones in the form of rectilinear junctions makes it possible to obtain a rupture of the connection zones facilitated during the application of constraints on the connection zones.

[0026] According to one example, the first transverse wall and the second transverse wall respectively describe a first circular arc and a second circular arc, the first circular arc and the second circular arc being configured so as to together form a single circular arc.

[0027] This configuration makes it possible to obtain construction elements which can make vary the shape of the facade, by selecting a rounded shape on one side of the building element.

[0028] According to an example: - the third additional transverse wall has a third rectilinear portion and a third additional rectilinear portion, the third rectilinear portion forming with the third additional rectilinear portion an angle of between 140° and 160° and - the fourth additional transverse wall has a fourth rectilinear portion and a fourth additional rectilinear portion, the fourth rectilinear portion forming with the fourth additional rectilinear portion an angle of between 140° and 160°, - the third rectilinear portion and the fourth rectilinear portion forming a continuous rectilinear portion positioned between the fourth additional rectilinear portion and the third additional rectilinear portion.

[0029] In the same way as for the second building block and for the third building block, the construction of the third additional transverse wall and of the fourth additional transverse wall makes it possible to vary the shape of the facade between a first side of the building element and a second side of the building element.

[0030] According to an example: - the first building block comprises a first upper face and a first lower face, the second building block comprises a second upper face and a second lower face, the third building block comprises a third upper face and a third lower face and the fourth building block comprises a fourth upper face and a fourth lower face, - the first lower face, the second lower face, the third lower face and the fourth lower face being opposite respectively to the first upper face, to the second upper face, to the third upper face and to the fourth upper face, - the first building block, the second building block, the third building block and the fourth building block comprise respectively on the first upper face, on the second upper face, on the third upper face and on the fourth upper face male assembly means and respectively on the first lower face, on the second lower face, on the third lower face and on the fourth lower face, female assembly means complementary to the male assembly means, so that the first building block, the second building block, the third building block and the fourth building block are configured to cooperate in superposition with at least one of a first similar building block, a second similar building block, a third similar building block and a fourth similar building block of a similar building element along a vertical axis, the vertical axis being perpendicular to an axis along which two building blocks of the same building element are successively positioned.

[0031] Due to the positioning of male assembly means and female assembly means (complementary to the male assembly means) on the construction elements, this configuration makes it possible to easily superimpose construction elements on top of each other.

[0032] According to one example, the plurality of building blocks consists of a first building block, a second building block, a third building block, and a fourth building block.

[0033] By "two integral elements" is meant the fact that the movement of a first element causes the movement of the second element linked to the first element. Thus, two elements integral with each other are elements which can be defined as being linked together or joined together.

[0034] The term "two dissociable elements" means two elements that can be isolated from one another. Thus, two dissociable elements are two elements that can be defined as being separable or disjoint from one another.

[0035] In the context of the present invention, "junction zone" defines a location by the three dimensions of space. Thus, a junction zone has a volumetric extent extending along a plane and is located at the location defined so as to encompass all the locations in space where two blocks must be joined.

[0036] It is specified that in the context of the present invention, the terms "vertical" or "horizontal" are to be taken into consideration according to the usual direction of use of construction elements so as to be able to construct a wall wall. Thus, the vertical direction (or the vertical plane) designates the direction (or the plane) in which the construction elements are stacked to form a wall wall consisting of the juxtaposition of the walls 23, 33, 34, 44, 41, 11, 12 and 22. The horizontal direction (or the horizontal plane) designates the direction (or the plane) in which the construction blocks of the same construction element are juxtaposed. The vertical direction is then perpendicular to the horizontal direction. The horizontal direction consists of a direction parallel to the plane of the horizon. The vertical direction consists of a direction perpendicular to the plane of the horizon.

[0037] The use of these words does not mean that slight variations around the directions vertical and horizontal are excluded from the invention. For example, an inclination relative to these directions of the order of + or - 10° is here considered as a minor variation around the two preferred directions. Furthermore, the adjectives "lower" and "higher" are to be taken in relation to the vertical direction; in the same context, a higher element will be located above (but not necessarily in contact with, or directly in line with) a lower element, following the vertical direction.

[0038] In the context of the present invention, the term "discontinuous" in the context of "discontinuous connecting zones" means that the junction zones in question are formed by several elements spaced from each other.

[0039] The term “face” means a two-dimensional element; the two-dimensional element is not necessarily located on the same plane and may be discontinuous.

[0040] The term “wall” means a three-dimensional element; the three-dimensional element is not necessarily located on the same plane and may be discontinuous.

[0041] The building element comprises a plurality of building blocks. The plurality of building blocks comprises a first building block 1, a second building block 2, a third building block 3 and a fourth building block 4. The building blocks 1, 2, 3, 4 are connected to each other but detachable at a longitudinal connection area 8 and a transverse connection area 9. The longitudinal connection area 8 and the transverse connection area 9 form a right angle with each other.

[0042] Typically, the construction element can be made of concrete. It can be produced by molding in one piece, that is to say that all the components of the construction element are made from a single material, concrete, and preferably in a single manufacturing step. This single-piece construction ensures high productivity and limits the quantity of parts to be brought to a construction site and handled on site.

[0043] At the same time, the invention offers great flexibility in the construction of works by allowing the construction element to be divided according to requirements.

[0044] More precisely, the construction element comprises different portions, called blocks, which can remain in place as a single piece or be detached from the element. This capacity is provided by connecting zones between the blocks which constitute zones less resistant than their environment, and in particular than the walls of the blocks. In this way, when a mechanical force is exerted at this location, it is easy to separate juxtaposed blocks by breaking the corresponding connecting zones. Typically, the connecting zones are made of the same material and in the continuity of the materials of the blocks. A break is favored at this location by the limitation of the section of the connecting zones; in fact, the connecting zones have a smaller section than the walls of the blocks which they join so that the stresses are more concentrated at their level, which makes them more fragile. A operator can therefore easily split the blocks at these locations.

[0045] Advantageously, the construction element comprises strictly four blocks together forming an element of substantially rectangular horizontal section. In this way, it is possible, for example, to use on site a subset of two blocks juxtaposed in the longitudinal direction or a subset of blocks juxtaposed in the transverse direction.

[0046] The building blocks may have a height of between 0.3 and 0.5 m, a width of between 1 and 1.5 m and a length of between 2 and 3 m. The height is taken according to the direction of stacking of two building elements on top of each other.

[0047] The building blocks may have cells (or empty areas) inside the building blocks. These cells may form openings inside the building blocks from one face to the other of a building block depending on the stacking direction of the building blocks. Two cells may be present on each side of the building element depending on the longitudinal direction of the building element. The longitudinal direction is the direction in which the building element has the greatest length. Four other cells may also be present in each building block. These four cells may be present in the center of each building block.

[0048] The third additional longitudinal wall 33, the second additional longitudinal wall 23, the third additional transverse wall 34, the fourth additional transverse wall 44, the fourth longitudinal wall 41, the first longitudinal wall 11, the first transverse wall 12, and the second transverse wall 22 may be flat or have a pattern making it possible to vary the decoration of the wall facade.

[0049] Advantageously, the third additional longitudinal wall 33 and the second additional longitudinal wall 23 may be parallel to the fourth longitudinal wall 41 and to the first longitudinal wall 11. Advantageously, the third longitudinal wall 31, the fourth additional longitudinal wall 43, the second longitudinal wall 21, and the first additional longitudinal wall 13 may be parallel to each other. Preferably, the second additional transverse wall 24, the third transverse wall 32, the first additional transverse wall 14 and the fourth transverse wall 42 may be parallel to each other.

[0050] Preferably, the longitudinal connection zone 8 comprises a first longitudinal connection zone 81 and a second longitudinal connection zone 82. Advantageously, the transverse connection zone 9 comprises a first transverse connection zone 91 and a second transverse connection zone 92.

[0051] Preferably, the first building block 1 comprises a first wall longitudinal 11, a first transverse wall 12, a first additional longitudinal wall 13 and a first additional transverse wall 14. The second building block 2 may comprise a second longitudinal wall 21, a second transverse wall 22, a second additional longitudinal wall 23 and a second additional transverse wall 24. Advantageously, the third building block 3 comprises a third longitudinal wall 31, a third transverse wall 32, a third additional longitudinal wall 33 and a third additional transverse wall 34. The fourth building block 4 may comprise a fourth longitudinal wall 41, a fourth transverse wall 42, a fourth additional longitudinal wall 43 and a fourth additional transverse wall 44.

[0052] According to a preferred example, the first additional longitudinal wall 13 is connected but separable from the second longitudinal wall 21 at the first transverse connection zone 91. Advantageously, the second additional transverse wall 24 is connected but separable from the third transverse wall 32 at the first longitudinal connection zone 81. Preferably, the third longitudinal wall 31 is connected but separable from the fourth additional longitudinal wall 43 at the second transverse connection zone 92. Preferably, the fourth transverse wall 42 is connected but separable from the first additional transverse wall 14 at the second longitudinal connection zone 82.

[0053] Said in another way, the first building block 1 may be integral but separable from the second building block 2 at the first transverse connection zone 91. The second construction zone 2 may be integral but separable from the third building block 3 at the first longitudinal connection zone 81. The third building block 3 may be integral but separable from the fourth building block 4 at the second transverse connection zone 92. The fourth building block 4 may be integral but separable from the first building block 1 at the second longitudinal connection zone 82.

[0054] Preferably, the first longitudinal connection zone 81 comprises elements not in contact with each other. Preferably, the second longitudinal connection zone 82 comprises elements not in contact with each other. Advantageously, the first transverse connection zone 91 comprises elements not in contact with each other. Advantageously, the second transverse connection zone 92 comprises elements not in contact with each other.

[0055] At the level of all the connection zones (having the particularity of being discontinuous) of the construction element, the mechanical force applied makes it possible to create a rupture zone due to the concentration of stresses at these locations. The longitudinal and transverse junction zones between the building blocks may be discontinuous, between the longitudinal and transverse junction zones, empty areas of material may be present so that they can form lumens extending from the upper end of a building block to the lower end of a building block along the vertical axis 90.

[0056] The longitudinal and transverse joining areas between the building blocks may extend from the upper end of the walls of the building blocks to the lower end of the walls of the building blocks that they are to be joined and detached. Thus, the longitudinal and transverse joining areas join the upper faces of the blocks to the lower faces of the blocks. The upper end and the lower end of the building blocks designate the free ends of the building blocks when they are not superimposed with other building blocks to form a wall (in the vertical direction). The longitudinal and transverse joining areas between the building blocks may be relatively small in the direction parallel to the axis along which two joined building blocks are successively positioned.

[0057] Advantageously, the first longitudinal rectilinear junctions 50 are integral on one side with the second additional transverse wall 24 and on the other side with the third transverse wall 32. The second longitudinal rectilinear junctions 51 may be integral on one side with the fourth transverse wall 42 and on the other side with the first additional transverse wall 14. Preferably, the first transverse rectilinear junctions 52 may be integral on one side with the first additional longitudinal wall 13 and on the other side with the second longitudinal wall 21. Preferably, the second transverse rectilinear junctions 53 are integral on one side with the third longitudinal wall 31 and on the other side with the fourth additional longitudinal wall 43.

[0058] The rectilinear junctions of the different blocks are preferably material elements extending between the upper and lower faces of the blocks; they run along the walls of the latter, leaving openings, preferably through openings, between the blocks. Preferably, the rectilinear junctions are parallel to each other and / or parallel to a height dimension of the blocks. It is understood that the junctions form a system of spacers between the walls of the juxtaposed blocks, preserving an intermediate gap and limiting the section of the connection zones. Three to five rectilinear junctions can be provided for each connection zone. Preferably, at least one connection zone comprises a rectilinear junction on the two edges of the blocks.

[0059] The first longitudinal rectilinear junctions 50, the second longitudinal rectilinear junctions 51, the first transverse rectilinear junctions 52 and the second transverse rectilinear junctions 53 may extend in the direction parallel to the surface on which they are positioned over a distance of between 0.2 and 0.3 m. The rectilinear junctions have a thin, narrow and elongated shape, i.e., two of their dimensions are smaller than the third. More precisely, two of its dimensions are 4 times, 6 times, 8 times or 10 times smaller than the third dimension. The two smaller dimensions may not be identical.

[0060] The first longitudinal rectilinear junctions 50, the second longitudinal rectilinear junctions 51, the first transverse rectilinear junctions 52 and the second transverse rectilinear junctions 53 may extend in the direction perpendicular to the surface on which they are positioned over a distance of between 0.1 and 0.15 m.

[0061] The first longitudinal rectilinear junctions 50, the second longitudinal rectilinear junctions 51, the first transverse rectilinear junctions 52 and the second transverse rectilinear junctions 53 may have a rounded or rectangular shape.

[0062] The first longitudinal rectilinear junctions 50 (or the second longitudinal rectilinear junctions 51 or the first transverse rectilinear junctions 52 or the second transverse rectilinear junctions 53) may be spaced apart from each other in the direction parallel to the surface on which they are positioned by a distance of between 0.2 m and 0.5 m. The distances between two of the first longitudinal rectilinear junctions 50 (or two of the second longitudinal rectilinear junctions 51 or two of the first transverse rectilinear junctions 52 or two of the second transverse rectilinear junctions 53) may be different depending on the two first longitudinal rectilinear junctions 50 (or the two second longitudinal rectilinear junctions 51 or the two first transverse rectilinear junctions 52 or the two second transverse rectilinear junctions 53) that are considered.

[0063] Preferably, the first transverse wall 12 and the second transverse wall 22 respectively describe a first arc of a circle 121 and a second arc of a circle 221. The first arc of a circle 121 and the second arc of a circle 221 can together form a single arc of a circle not having angular zones.

[0064] Advantageously, the third additional transverse wall 34 has a third rectilinear portion 341 and a third additional rectilinear portion 342. Preferably, the third rectilinear portion 341 and the third additional rectilinear portion 342 form an angle between them of between 140° and 160°. Advantageously, the fourth additional transverse wall 44 has a fourth rectilinear portion 441 and an additional fourth rectilinear portion 442. According to a preferred example, the fourth rectilinear portion 441 and the additional fourth rectilinear portion 442 form an angle between them of between 140° and 160°. The construction element is configured such that the third rectilinear portion 341 and the fourth rectilinear portion 441 can form a rectilinear portion (not having angular zones) positioned between the additional fourth rectilinear portion 442 and the additional third rectilinear portion 342.

[0065] According to a preferred example, the first building block 1 comprises a first upper face 61 and a first lower face 71, the second building block 2 comprises a second upper face 62 and a second lower face 72, the third building block 3 comprises a third upper face 63 and a third lower face 73 and the fourth building block 4 comprises a fourth upper face 64 and a fourth lower face 74. Preferably, the first building block 1 comprises, on a first upper face 61, male assembly means 65 and on a first lower face 71, female assembly means 75. Advantageously, the second building block 2 comprises, on a second upper face 62, male assembly means 65 and on a second lower face 72, female assembly means 75.Preferably, the third building block 3 comprises, on a third upper face 63, male assembly means 65 and on a third lower face 73, female assembly means 75. According to a preferred example, the fourth building block 4 comprises, on a fourth upper face 64, male assembly means 65 and on a fourth lower face 74, female assembly means 75.

[0066] The male assembly means 65 can be defined as notches being able to cooperate with the empty spaces of a similar construction element located above said construction element and the spaces being able to cooperate with the notches of a similar construction element located below said construction element.

[0067] The first lower face 71, the second lower face 72, the third lower face 73 and the fourth lower face 74 may be respectively opposite the first upper face 61, the second upper face 62, the third upper face 63 and the fourth upper face 64.

[0068] The female assembly means 75 may be complementary in shape to the male assembly means 65, so that the first building block 1, the second building block 2, the third building block 3 and the fourth building block 4 are configured to cooperate in superposition with at least one of a first similar building block 1', a second similar building block 2', a third similar building block 3' and a fourth similar building block 4. similar construction 2', a third similar building block 3' and a fourth similar building block 4' of a similar building element along a vertical axis 90. The vertical axis 90 is parallel to the depth direction of the building blocks 1, 2, 3, 4. The depth direction is perpendicular to the directions in which the longitudinal connection area 8 and the transverse connection area 9 extend.

[0069] The male assembly means 65 may have a shape describing a quadrilateral or a half-sphere or a rounded shape. The female assembly means 75 then describe the shape complementary to the shape of the male assembly means 65.

[0070] The arrangement in superposition of the different construction elements can therefore be achieved by a vertical translation movement along the vertical axis 90, thus making it possible to position or separate two construction elements in contact one above the other.

[0071] The vertical axis 90 can also be defined as being perpendicular to the axes along which two building blocks integral with the same building element are successively positioned.

[0072] Advantageously, the plurality of building blocks consists of a first building block 1, a second building block 2, a third building block 3 and a fourth building block 4.
