Definitions

  • the present invention relates to the field of building, more particularly the construction of houses or buildings from building blocks. More particularly, the invention relates to the construction of a wall or the like from stackable building blocks.
  • the invention relates to wall-type construction or the like, extending at least in one horizontal direction and one vertical direction.
  • This construction comprises a plurality of rows of superimposed building blocks, and has a building block of substantially parallelepiped shape.
  • Each building block comprising an upper face at least capable of being associated with the lower face(s) of one or two other similar building blocks, a lower face at least capable of being associated with the upper face(s) of a or two other similar building blocks.
  • Concrete or mortar blocks are very commonly used for the construction of construction works.
  • the following posts show examples of concrete blocks: EP0726369 , US5775047 , FR3032735 And DE4402135 .
  • the present invention aims to remedy these drawbacks.
  • the building block makes it possible to insulate and soundproof. It is also lighter, easier to transport and handle.
  • Liquid polyurethane transforms into foam through a chemical reaction (called polymerization) using humidity in the air or an addition of water. It is generally packaged in an aerosol can to be shaken before use. It can be used indoors and outdoors, adheres extremely well to most materials (concrete, brick, plastic, plaster, metals, etc.), has exceptional insulating qualities (1 centimeter of foam would be equivalent to 40 meters of concrete) and swells enormously (a 500 milliliter bomb gives approximately 20 liters of foam).
  • the rear face comprises at least one rectangular facing, of normally rectangular section.
  • the front face comprises at least one rectangular facing, of normally rectangular section.
  • the rear face or the front face comprises two rectangular facings, of normally rectangular section between which there is a hollow joint.
  • FIG. 1 represents a building block 20 of substantially parallelepiped shape and comprises an upper face 25 at least capable of being associated with the lower face(s) of one or two other similar building blocks (not shown), a lower face (not shown ) at least capable of being associated with the upper face(s) of one or two similar building blocks 20 (not shown), at least two vertical openings 22.
  • the building block 20 comprises two lateral faces with a recess 21 and a front face 24 and a rear face 23.
  • Building block 20 includes a quantity of expanding foam which is 4.6% by weight sand.
  • the quantity of expanding foam is 70 ml and the quantity of sand is 1.5 kg.
  • the percentage between 3 and 6% of the weight of sand corresponds to the good compromise between the quantity of expanding foam and the good mechanical strength of the building block 20.
  • FIG. 2 represents a top view of another example of a building block 20. This figure repeats certain elements of the previous figure.
  • the front face 24 comprises a rectangular facing 26, of normally rectangular section.
  • the joint extends all around the facing 26 on the horizontal edge of the front face 24 and the vertical edge.
  • the building block 20 has two vertical openings 22.
  • the two vertical openings 22 are rectangular and arranged symmetrically on either side of the transverse median plane of the building block 20.
  • each reinforcement 21 reveals a vertical bead 28 in relief intended respectively to come to bear against the vertical bead 28 of the adjacent building blocks 20.
  • FIG. 3 represents a perspective view of another example of a building block 20. This figure repeats certain elements of the previous figure.
  • the building block 20 has two vertical openings 22.
  • the front face 24 comprises two rectangular facings 26, of normally rectangular section. Between the two rectangular facings 26 there is a hollow joint 27. In other words, each facing 26 is bordered on one of its vertical edges by a hollow joint 27.
  • Hollow joint 27 means a groove or groove in the material.
  • each facing 26 is always separated from one of the adjacent facings 26 by a joint 27: either constituted between two facings 26 of the same building block 20, or constituted by a facing 26 of a block and another adjacent facing 26 of another adjacent building block 20.
  • the joints play the role of hollow joints made, in traditional assembly with mortar.
  • FIG 4 represents a top view of another example of a building block 20. This figure includes certain elements from the previous figures.
  • the rear face 23 comprises two rectangular facings 26, of normally rectangular section and the front face 24 comprises two rectangular facings 26, of normally rectangular section.
  • one of the side faces has two large beads 28 (the one on the right in the figure), that is to say it is wider than the other side face.
  • the joint of the facing 26 adjacent to said side face does not exist.
  • FIG. 5 represents a top view of another example of a building block 20. This figure includes certain elements from the previous figures.
  • one of the side faces has two large beads 28 (the one on the left in the figure), that is to say it is wider than the other side face.
  • the joint of the facing 26 adjacent to said side face does not exist.
  • FIG. 6 represents a top view of another example of a building block 20. This figure includes certain elements from the previous figures.
  • the rear face 23 comprises two rectangular facings 26, of normally rectangular section and the front face 24 comprises two rectangular facings 26, of normally rectangular section.
  • the building block 20 has symmetry on either side of the transverse median plane of the building block 20.
  • FIG. 7 represents a top view of the assembly of two building blocks. This figure represents the assembly of a wall corner made up of two building blocks 20.
  • FIG 8 represents a top view of an example of a building block 20 according to the invention. This figure incorporates certain elements from the previous figures.
  • the rear face 23 has a rectangular facing 26
  • the front face 24 has a rectangular facing 26.
  • the width of the building block 20 has increased.
  • the insulating part 29 extends across the width of the building block 20.
  • the width is defined between the front face 24 and the rear face 23.
  • the height is defined between the upper face 25 and the lower face.
  • the length is defined between the two side faces.
  • FIG. 9 represents a top view of another example of a building block 20. This figure repeats certain elements of the previous figure.
  • the rear face 23 comprises two rectangular facings 26, of normally rectangular section and the front face 24 comprises two rectangular facings 26, of normally rectangular section.
  • FIG. 10 represents a top view of another example of a building block 20. This figure shows certain elements of the figures 8 and 9 .
  • one of the side faces has two large beads 28 (the one on the left in the figure), that is to say it is wider than the other side face.
  • the joint of the facing 26 adjacent to said side face does not exist.
  • the width of the bead 28 is made up of the thickness of the facing 26, the joint of the facing 26 and part of the width of a side face.
  • FIG. 11 represents a top view of another example of a building block 20. This figure shows certain elements of the figure 8 to 10 .
  • the rear face 23 comprises two rectangular facings 26, of normally rectangular section and the front face 24 comprises a rectangular facing 26, of normally rectangular section.
  • FIG. 12 represents a top view of another example of a building block 20. This figure shows certain elements of the figure 8 to 11 .
  • the building block 20 has four vertical openings 22.
  • the four vertical openings 22 are rectangular and arranged symmetrically on either side of the transverse median plane of the building block 20. According to a variant, two of the four vertical openings 22 have insulation.
  • the joint between two facings 26 makes it possible to position a rail which will include, for example, electricity, antenna, internet wires, etc. Power outlets are then positioned where desired on the rail and connected to the electric wire of the rail.
