  • This invention is in the context of development projects, often, but not exclusively private, such as the realization of retaining walls or fence walls in a garden of a particular house.
  • the trend has been on the market to use noble natural materials and materials, such as stone, to carry out such projects.
  • the need to build retaining walls or fences at increasingly higher heights is clearly visible in the market.
  • the building materials industry has turned to materials that mimic the rustic look and warm colors of natural stone. Concrete is a durable and durable material, easy to rework to give an aesthetic appearance equivalent to any other product such as natural stone, wood, marble, etc., it lends itself to such use.
  • concrete building blocks part of which has at least one surface having the appearance of natural stones.
  • This type of block is generally used to make walls using a technique using anchors called “geogrids”.
  • This technique is particularly used in large-scale public projects and has the advantage of simultaneously allowing the mounting of walls and their loading, ie backfilling and compaction. Indeed, said geogrids are in this case horizontally inserted at several levels in the retaining wall, as well as in the ground behind this wall.
  • This technique is mainly suitable for medium and high-rise retaining walls and executed by experienced workers, because of its complexity of realization.
  • the object of the present invention is to obviate the aforementioned drawbacks of current systems and to provide building blocks of concrete walls to achieve a wall imitating the natural appearance of the stone and can reach heights desired.
  • the invention aims to simplify the user the realization of such walls that can be carried out by unskilled workers in this field. Furthermore, the invention also targets the simple manufacture of such building blocks.

  • the invention provides a wall construction block, at least the outer walls of the block surrounding said at least one cell or a thickness relative to the width of the block in the range of 1: 3 to 1: 6 , so as to allow the mechanical aging of the lateral surfaces of the block, and wherein said at least one cell is disposed in the horizontal plane of the building block so that the cells of the building blocks of different dimensions are at least partially superimposed during the stacking of these for the construction of walls, so as to allow the location of vertical connection means.
  • This has the advantage that walls imitating the appearance of natural stones can be mounted at average heights of up to about two to three meters, both for fence walls and retaining walls.
  • the invention provides a foundation member adapted for use with such building blocks and having an upper portion having a bearing surface, a lower portion having a seating surface, and a central portion having a hollow space. having at least one lateral opening.
  • the invention provides a corresponding vertical connection means having a first portion extending vertically and a second portion extending horizontally, the second portion having a shape corresponding substantially to the contours of the hollow space of the element. foundation, so as to laterally insert the connecting means in the foundation element.
  • the present invention provides a method of manufacturing such a wall building block.
  • the method comprises in particular the manufacturing steps of the concreted parts comprising several building blocks cast together, the latter being separated by cleavage into individual building blocks and then mechanically aged by passage through a rotary drum or by another technique.
  • blocks, according to the present invention can be manufactured by a simple mechanical aging process and without too much loss.
  • the invention also proposes a mold for the implementation of this manufacturing method.
  • FIGS. 1a, 1b and 1c show plan views illustrating building blocks of walls according to the present invention which make it possible to make a retaining wall or a wall wall imitating the appearance of a natural stone wall and mounted in Roman alphabet, this up to heights of about two to three meters in case of armed wall.
  • the wall building blocks 1, 2, 3, 4, 5, 6, 1 ', 2', 3 ', 4', 5 ', 6', according to the present invention are substantially hexahedral in shape and comprise at least one rough side surface 11 that mimics the appearance of the natural stone.
  • These blocks also comprise at least one cell 12 vertically traversing said blocks.
  • FIG. figure 1a To the figure 1a are represented standard parts 1, 2, 3 of a first height H 1 , these standard blocks having, as visible in FIG. figure 1a , a trapezoidal base surface.
  • the blocks can be mounted in a straight line as illustrated in the figure 1g or in a convex and / or concave curve with a radius as a function of the angle of the inclined sides of the trapezium as illustrated in FIG. figure 1h .
  • the figure 1b shows head pieces of the building blocks according to the present invention, these head pieces having only one inclined side instead of two, like the standard pieces shown in FIG. figure 1a .
  • FIG 1c finally, is illustrated a corner piece of such a building block, a portion of one of the two side surfaces has been adapted to have an edge for receiving a piece having the same dimensions and angle; therefore to receive one of the standard parts illustrated in the figure 1a .
  • a building block according to the present invention have at least one rough side surface 11 imitating the appearance of the natural stone, as well as at least one cell 12 traversing vertically said block.
  • these building blocks are distinguished by the fact that at least the outer walls 13 of the block surrounding said at least one cell 12 have a thickness relative to the width B of the block in the range from 1: 3 to 1 : 6, so as to allow the aging of the side surfaces of the block. Indeed, in this way the thickness of these outer walls 13 is sufficient to allow mechanical treatment of these concrete blocks according to the present invention. This treatment artificially ages the outer surfaces of the blocks, to give them an aesthetic appearance approaching almost perfectly the appearance of natural stones, as will be explained in more detail later in the description.
  • said at least one cell is disposed in the horizontal plane of the building block so that the cells 12 of the building blocks of walls of different dimensions are at least partially superimposed during the stacking of the latter for the construction of a wall, so as to allow the location of vertical connection means 8, this being clearly visible in the figures 2b , 2c, 2d and 2e .
  • the cells in the blocks according to the present invention serve, on the one hand, to lighten the blocks and to ensure ease of handling and assembly on site.
  • these cells are useful during the construction of walls using these blocks, either to anchor reinforcement reinforcing said wall, or to contain concrete or any another bonding or stabilizing material adapted to stabilize the mounted walls, as will be further detailed below in the description.
  • the figure 1a also shows that the wall building blocks according to the present invention may have at least two, preferably at least three lengths L 1 , L 2 , L 3 and / or two heights H 1 , H 2 different for a block width B given.

  • This base length L B may, for example, be identical to the length L 1 of the first, smaller standard part illustrated in FIG. figure 1a having only one cell 12.
  • the wall building blocks according to the present invention may also have at least two heights H 1 , H 2 different, so that blocks of different dimensions, for example at least six different embodiments in the presence of for example three lengths and two different heights, can be assembled in a chaotic manner according to the builder's taste when making the wall. If both longitudinal side surfaces are aged, the blocks, in particular those of trapezoidal shape, can be used reversibly in on-line or curved fixtures, which enhances the aesthetic appearance due to a slight modification of the length visible from each block.
  • a wall building block according to the present invention comprises a number of cells corresponding to its length, this number being in particular proportional to the total length of the block.
  • the cells 12 of a block are arranged substantially around the center of each part of the block corresponding to a base length L B.
  • the cells are superimposed and form channels around centers of said base length L B over the entire height of the wall.
  • the distance between the centers of each portion corresponding to a cell and having a length corresponding to said base length L B is regular, which allows a regular positioning of the connecting means or frames that are possibly integrated into the wall to strengthen it.
  • FIG. 2a shows schematically a slice of wall mounted in Roman alphabet with building blocks of different lengths and heights and having a visible rough surface imitating the appearance of natural stones, roofs 10 of the same appearance being placed at the top of the wall to allow the evacuation of the rainwater and to direct their runoff outside the apparent faces of the wall.
  • the figure 2b shows a horizontal section along the BB line of the wall slice shown in the figure 2a and the Figure 2c shows a cross section along the line CC of the same wall.
  • a wall construction block according to the present invention may also comprise, on its upper surface and / or lower, a longitudinal housing for the location of a horizontal connection means 8 '.
  • the longitudinal housing may in particular be made by a reservation, or even a chamfer, such as visible for example on the upper surface of the blocks illustrated in perspective view at the figure 1d .
  • An armature 8 'placed in a longitudinal housing is shown in the perspective illustrated by way of example at figure 2e .
  • This aspect is further reinforced by the fact that the present invention also provides foundation elements 7 adapted for use with wall building blocks as described in detail above.
  • Such a foundation element 7 is distinguished by the fact that it comprises an upper portion 7.1 having a bearing surface 7.1.1 having a width B F substantially corresponding to a block width B of said building blocks.
  • This foundation element 7 also comprises a lower portion 7.2 having a laying surface 7.2.1 having an enlarged width B A and a central portion 7.3 having a hollow space 7.3.1 having at least one lateral opening 7.3.3, an upper opening 7.3.4, and at least one sidewall 7.3.2 for increasing the rigidity of the foundation element 7.

  • Such vertical connection means 8 inserted and placed in a stable position is illustrated by way of example to Figures 3a and 3b .
  • the top view of the foundation element 7 visible as an example to the figure 3b also shows that this element 7 preferably comprises at least one stop 7.1.2 and / or at least one recess on the wall at least partially surrounding said upper opening 7.3.4 of the hollow space 7.3.1 of the central portion 7.3. It is in this way that the stable position of the vertical connection means 8 introduced into said hollow space 7.3.1 is defined. It is however not required that the foundation element 7 comprises such a stop 7.1.2 and the wall surrounding, at least partially, said upper opening 7.3.3 could also be completely rounded or have any other suitable shape.
