  • the sleeves are set back from the side edges of the walls.
  • Concrete can also be poured between two neighboring elements ensuring a continuity of the arch structure of the carrying part of the wall.
  • each sleeve is surmounted by a support adapted to locally support reinforcing irons for reinforcing the supporting structure of the basement wall.
  • each support consists of an element connecting the two walls transversely, the support having a U-shaped section comprising two parallel branches secured respectively to the walls, and which are joined by an intermediate branch resting on the intermediate branch of the corresponding sleeve.
  • the reinforcing irons can thus be placed in the element without touching its flat walls so that they are properly embedded in the concrete during pouring. In this way, a reinforced wall structure is obtained which has perfectly calibrated mechanical characteristics.
  • the element is provided with an assembly means adapted to allow its assembly with another element, wherein the elements are mutually prolonged by being in contact by the lateral edges of the two walls.

  • the method consists in casting a floating slab inside the perimeter delimited by the elements and casting the basement wall with the same delivery of concrete.
  • the method consists in superimposing several rows of elements, casting the basement wall, waiting for its setting, and then laying a floor.
  • a basement wall is also proposed.
  • the two faces of the wall are constituted respectively by two insulating walls from a point of view thermal, the central part of the wall being made of concrete, transverse passages being arranged through the central portion of the wall at its lower part.

Concrete can then be poured between the two walls to form the structure of the basement wall when the elements are juxtaposed and placed on the foundation .
  • the walls 110 and 120 have a rectangular shape and are arranged parallel to each other and being placed opposite each other.
  • the sleeves 130 are separated by an interstice I allowing the poured concrete to go down bypassing the sleeves 130 so that it can take hold on the foundation by forming arches in the supporting structure of the wall.
  • the sleeves 130 are arranged parallel to the upper edges 111 of the walls 110 and 120 by being set back from them in order to be able to cover the sleeves with concrete in order to form a belt chaining in the supporting structure of the basement wall. They are also set back from the side edges 112 of said walls so that the concrete can also flow between two neighboring elements 100 assembled to continue the arch support structure of the basement wall.
  • the sleeves 130 also limit the amount of concrete needed to fill an element and therefore the amount of concrete necessary for the construction of the basement wall while providing sufficient strength.
  • Each sleeve 130 is hollowed out internally.
  • the hollow shape of the sleeves 130 makes it possible to lighten the construction of the shuttering element 100 and also constitutes a transverse sheath allowing the passage through the basement wall, at the end of its construction, of pipes or other connecting ducts. to the dwelling.
  • Each sleeve 130 has a structure having, in a plane transverse to the element 100, an inverted U-shaped section, that is to say a structure in the form of an arch, comprising two parallel branches 131 and 132 joined by an intermediate branch 133 rounded so that the concrete can flow easily around the sleeve and between the parallel branches of two adjacent sleeves.
