Definitions

  • the present invention relates in particular to a construction element as well as to a construction assembly comprising several elements allowing the composition of a wall using the elements in question.
  • a preferred application concerns the building and public works industry, in particular for the creation of low walls, retaining walls, noise barriers or others.
  • the inclined wall formed by the portion of increasing thickness forms a favorable triangulation element the resistance to rupture of the second wall. The stability of the whole is therefore improved.
  • Another advantage of the portion of linearly increasing section is to offer a surface favorable to the head-to-tail cooperation of two similar superimposed elements.
  • the invention forms an inclined wall which can serve as a guide for insertion of an element superimposed on another in a direction while the inclined wall formed on the superimposed element provides insertion guidance in a direction perpendicular to the first one.
  • the two elements can thus be nested one inside the other in a progressive manner, even if their relative starting position is not precise.
  • the element is perforated, therefore having an advantageous volume/weight ratio.
  • This openwork character can, moreover, be through from the base face to the opposite face with two stages, which simplifies manufacturing, limits the weight and ensures complete backfilling which can pass through a plurality of superimposed elements.
  • the element can be relatively heavy and for example cannot be handled by hand on the construction site.
  • the formation of the inclined internal face of the invention simplifies positioning using machines, even if the initial positioning accuracy of the element is low; the inclined internal face can be used in this context for progressive guidance until the final position of the element.
  • the invention further relates to an assembly comprising a plurality of construction elements according to the invention allowing in particular the composition of a wall wall; this composition can be with a bend, such a bend being able to be curved (concave or convex) or even at a right angle.
  • this composition can be with a bend, such a bend being able to be curved (concave or convex) or even at a right angle.
  • at least two elements will be superimposed to form a stack.
  • the superimposed elements can be offset in the longitudinal direction so as to form a retaining wall with a fruit. Angles can also be formed, in particular at right angles by head-to-tail nesting of superimposed elements.
  • the invention can be made from concrete, for example by molding.
  • the concrete can have a conventional reinforcement.
  • the element is in one piece, in a single coherent element called construction element.
  • face we mean a two-dimensional element, the two-dimensional element is not necessarily located on the same plane and can be discontinuous.
  • wall is meant a three-dimensional element, the three-dimensional element is not necessarily located on the same plane and can be discontinuous.
  • the perspective of the figure 1 adopts a three-dimensional reference frame corresponding to three preferred directions of the element of the invention.
  • the dimension L corresponds to the longitudinal direction of the construction element 1; advantageously, it is the main dimension of the element, but this case is not limiting.
  • the dimension l corresponds to the lateral or transverse direction of the element; it is preferably oriented according to the width of the wall composition to be constructed.
  • the dimension h forms the height of element 1; although this is not limiting, it is advantageously following this direction that the height of the wall composition is constructed.
  • the construction element 1 has a plurality of faces which can in particular serve as contact surfaces with other elements or with the ground, or serve as facade parts.
  • a front face 2 is constituted by means of a first wall 8 referenced in perspective view on the figure 1 .
  • the front face 2 may be flat or present a pattern allowing you to vary the decor of the wall facade.
  • a rear face 3 is also visible in all of the figures and is carried by a second wall 9.
  • the first and second walls 8, 9 are parallel between them.
  • the second wall 9 has a width dimension less than that of the first wall 8.
  • the first and second walls 8, 9 are connected by two other walls, respectively third wall 10 and fourth wall 11.
  • the latter have a preferred orientation preferably perpendicular to that of the first, second walls 8, 9.
  • the walls 10, 11 are directed along the height of the construction element 1.
  • the third and fourth walls 10, 11 are parallel to each other. In the illustrated embodiment, they are spaced in the transverse direction and define, with the first and second walls 8, 9, an opening passing right through the construction element 1. This area can be backfilled during construction. from the wall.
  • a preferred configuration is that the spacing between the third and fourth walls 10, 11 is less than the width dimension of at least one of the first wall 8 and the second wall 9.
  • a slice of each of the four walls 8, 9, 10, 11 thus described defines a base face 6 of the element 1.
  • This set of first slices is preferably coplanar so as to define a planar base face 6; it will however be seen that it can include hollow areas used for nesting with other elements. It is also preferably oriented perpendicular to the four walls 8, 9, 10, 11.
  • the second wall 9 comprises a portion of linearly increasing thickness 13 in the direction of the base face 6 joining the third and fourth walls 10, 11 and forming an inclined internal face 91 of the second wall 9, opposite the rear face 3.
  • the inclined internal face 91 then makes it possible to better distribute the mechanical forces exerted on the construction element 1.
  • the portion of increasing thickness makes it possible to define a space interior to the element 1 and having the shape of a cavity gradually opening towards the front face 2. While forming this cavity of variable vertical section, the mechanical resistance is high thanks to the large section of the second wall 9 carrying the rear face 3 in its basal part. In particular, at the level of the junction between the second wall 9 and the third and fourth walls 10, 11, the quantity of material is significant which ensures good transmission of forces. Furthermore, when the element 1 of the invention is superimposed with a similar element 1, and there is a propensity of the wall thus formed to tilt towards the front face 2, the inclined face 91 formed by the portion of increasing thickness 13 forms a triangulation element favorable to the breaking resistance of the second wall 9. The stability of the assembly is therefore improved.
  • Another advantage of the portion of linearly increasing section 13 is to offer a surface favorable to the head-to-tail cooperation of two similar superimposed elements 1.
  • the invention forms an inclined face 91 which can serve as a guide for insertion of an element 1 superimposed on another element 1 in one direction while the inclined face 91 formed on the superimposed element 1 ensures guidance of insertion following a direction perpendicular to the first.
  • the two elements 1 can thus be nested one inside the other in a progressive manner, even if their relative starting position is not precise.
  • the portion of linearly increasing thickness 13 is surmounted by a portion called the terminal portion 14, opposite the third and fourth walls 10,11, said terminal portion 14 is characterized by a constant thickness.
  • the terminal portion 14 then forms a notch, which can serve to improve the cooperation between the construction element 1 and another construction element 1 having at least one recess intended to accommodate the terminal portion 14.
  • the recess is preferably located on the base face 6 and appears in the form of at least one groove 61, hollows and notches are complementary.
  • the limitation between the portion of linearly increasing thickness 13 and the terminal portion 14 is located at the same height as the upper end of the front face 2.
  • the groove 61 is configured to authorize insertion into the groove 61 of the terminal portion 14 of another element 1.
  • This other face 15 is formed by second slices of each of the first, second, third and fourth walls 8, 9, 10, 11.
  • the highest point of the construction element 1 is, at the level of this other face 15, located on the second wall 9.
  • the rear face 3 is raised. Thanks to these arrangements, the second wall 9 can cooperate with a recessed abutment element on the base face 6 of a superimposed element, so as to retain, in a front/rear direction, the stack as shown in figure 2 .
  • the groove 61 can be flared towards the base face 6. Thanks to this shape, the overlapping nesting of two similar elements can be achieved even if the initial relative positioning between the two elements 1 is not perfect, the flared part serving to gradually guide the terminal portion 14 in the groove 61. It is also very advantageous that the construction element 1 comprises several grooves 61. In fact, this makes it possible to modify the place of cooperation of the terminal portion 14 in relation to a superimposed construction element 1, so as to vary the fruit of the wall to be formed. By “fruit of the wall”, we mean the obliquity of the exterior face of the wall.
  • the grooves 61 can extend over the entire length L of the element 1 in the longitudinal direction or can extend for example over only half the length L of the element 1 in the longitudinal direction.
  • the grooves 61 can be located along the third and fourth walls 10 and 11 on the base face 6, in addition to being located at the level of the second wall 9 on the base face 6.
  • the other face 15, thus constituted, has a first stage 151, called the front stage, corresponding to a portion of the second sections, in particular the second section of the first wall 8, and a second stage 152, called the rear stage, corresponding to a portion of the second slices, in particular of the second slice of the second wall 9.
  • the second stage 152 corresponds to the upper end of the terminal portion 14.
  • the connecting edge 12 is preferably straight. It is advantageously perpendicular to floors 151, 152.
  • the other face 15 comprises a flat bottom 150 defined by a portion of the second edges, in particular the edges of the third and fourth walls 10,11, the flat bottom 150 being connected, from a first side, to the inclined internal face 91.
  • flat bottom 150 is connected by a second side to the connecting edge 12.
  • the third wall 10 and the fourth wall 11 respectively define a first sidewall 5 and a second sidewall 4 spaced in a transverse direction, and each connecting the first and second walls 8, 9. A portion of the first sidewall 5 and a portion of the second side 4 are then included in the flat bottom 150.
  • the flat bottom 150 is located at half a height dimension of the front face 2.
  • the base face 6 of one of the elements 1 is found at the same height level as the other face 15 of the other element 1.
  • the terminal portion 14 is absent from the block, the upper end of the front face 2 and the upper end of the rear face 3 are at the same height.
  • the grooves 61 are absent according to this embodiment.
  • the first stage 151 comprises a portion of the second section of the second wall 9 defining the rear face 3 and a portion of the second section of the third and fourth walls 10, 11.
  • the second stage 152 it comprises a portion of the second slice of the first wall 8 defining the front face 2 and a portion of the second slice, raised, of the third and fourth walls 10, 11.
  • the height of the rear face 3 is greater and preferably equal to twice the height of the front face 2.
  • FIG. 2 shows a first possibility of cooperation between different elements 1.
  • the elements 1 are superimposed so that the base face 6 of an element 1 is in contact with the other face 15 of an element 1 located below.
  • the terminal portion 14 of an element 1 is in the groove 61 of another element 1.
  • the elements 1 are strictly superimposed without any longitudinal offset.
  • the wall facade is then formed, without discontinuity, by the association of the front faces 2.
  • the intermediate spaces between the superimposed elements, particularly between the first floor 71 of a lower element relative to the base face 6 of an element located above, can be filled in the form of embankments.
  • the portion of linearly increasing thickness 13 forms an angle greater than 20° with the rear face 3.
  • a first set of elements 1 is superimposed so as to form a first facade direction; preferably, this superposition is carried out so that the base face 6 of the elements is located downwards and the other face 15 is located upwards.
  • a first stack of elements 1 is configured to cooperate with an adjacent stack of elements 1 of the first facade direction.
  • the elements 1 of this first stack of the second facade direction are turned over relative to those of the adjacent stack of the first direction of facade so that their base face 6 is directed upwards.
  • first stage 151 of these elements 1 applies to the first stage 151 of the elements 1 of the other stacking, the longitudinal directions of the elements being perpendicular between the two stacks assembled at an angle. It is understood that the assembly thus constituted alternates the installation of an element 1 of the first stack and of an element 1 of the second stack. An element 1 of a first stack is in contact with at least another element 1 of the same stack and an element 1 of the other stack.
  • the aspect ratios of the elements are configured so that, in this position, the front faces 2 of the two stacks are in contact or close, forming a right angle, by the edge of the vertical edge of the first wall 8 elements 1.
  • the connecting edge 12 of the elements of one stack applies to one of the sides 4, 5 of an element 1 of the other stack.
  • this 90° cooperation in the longitudinal direction of the elements forms an assembly substantially as long as it is wide.
  • the elements, in their longitudinal direction to have a dimension of less than 20% greater than their largest width dimension, for example the width dimension of the front face 2.
  • the length of an element 1 is less than or equal to the sum of the width of its front face 2 (corresponding to the width of the first wall 8) and twice the maximum thickness of the wall 8.
