Definitions

  • the present invention relates to building and construction and more particularly to a prefabricated construction element such as a beam or even a pre-slab.
  • the invention also relates to a method for manufacturing such a construction element.
  • thermal bridges that is to say that of the path of conduction of heat or cold by the continuity of a heat-conducting material from the exterior of the building to the interior. This is particularly the case for floors which form thermal bridges due to their contact with the exterior walls of the building.
  • pre-slabs each comprising a concrete body and at least two fixing bases anchored inside the concrete body and separated from each other by a predefined distance.
  • Each pre-slab further comprises reinforcements anchored in the corresponding concrete body so as to extend between two consecutive fixing bases.
  • An operator therefore arranges the pre-slabs along a wall and then inserts a block of thermally insulating material into each fixing base.
  • the reinforcements protruding towards the inside of the building are coated so as to be secured to the floor.
  • Reinforcements protruding from the other side of the thermally insulating body are then in turn embedded in an external concrete element continuing the construction of the wall. In this way, the floor and the wall are linked and the blocks of thermally insulating material arranged between them, via the bases, limit the corresponding thermal bridges.
  • An object of the invention is to provide a prefabricated building element which makes it possible to deal more effectively with thermal bridges, in particular, although not exclusively, between a wall and a floor.
  • An object of the invention is also to propose a method of manufacturing such a construction element.
  • the subject of the invention is a prefabricated construction element with the characteristics of claim 1, comprising a concrete body and at least one main thermal insulation unit secured to the concrete body, the main unit being arranged to protrude from an upper face of the concrete body.
  • the prefabricated construction element comprises at least one secondary thermal insulation and structural support unit comprising a specific concrete block having a reduced thermal conductivity of less than 1 watt per Kelvin meter and reinforcements arranged in said block, the block extending contiguous to the main unit so that said main unit is anchored in said specific concrete block.
  • the construction element according to the invention makes it possible to ensure continuity of the thermal insulation over the entire length of the construction element with an alternation of main thermal insulation zones at the level of the main units and of secondary thermal insulation zones at secondary units. This makes it possible to deal much better with the problems of thermal bridges.
  • the construction element of the invention is a pre-slab
  • continuity of the thermal insulation of the floor is thus ensured over the entire length of the wall/floor connection, which limits the wall/floor thermal bridge.
  • the secondary units perform both a thermal protection function thanks to the specific concrete block, and both a structural support function thanks to the reinforcements but also to the specific concrete block.
  • the main unit makes it possible directly to serve as a formwork portion for the manufacture of the secondary unit, which simplifies the manufacture of the construction element.
  • the main unit thus makes it possible directly to serve as a formwork portion for the manufacture of the secondary unit, which simplifies the manufacture of the construction element.
  • the terms “upper”, “lower” ... must be understood according to a position in service of the construction element, that is to say once the construction element has been placed on a building under construction (for example when the construction element is a pre-slab, the position in service is when the pre-slab is mounted at the level of the associated portion of the wall).
  • the construction element according to the first embodiment of the invention is a pre-slab 1 which therefore aims to treat the thermal bridges between a floor 2 and an adjacent wall 3 said floor 2.
  • the pre-slab 1 comprises a concrete body 4, for example of prestressed concrete comprising prestressing cables oriented longitudinally and parallel to each other.
  • the pre-slab 1 also comprises here main units 5 of thermal insulation.
  • the main units 5 are all secured to the concrete body 4 by being here anchored therein. More precisely, the main units 5 are here anchored in the concrete body 4 by being separated from each other by a predefined distance.
  • the main units 5 are arranged so as to protrude from the upper face of the concrete body 4.
  • the main units 5 are shaped so as to extend substantially at least over the entire height of the pre-slab 1. This thus allows to significantly reduce thermal bridges between floor 2 and the adjacent wall.
  • the main units 5 are arranged at the same longitudinal edge 6 of the pre-slab 1 but with an offset vis-à-vis this longitudinal edge 6. In this way, the main units 5 are here completely coated in the concrete body 4 which ensures good attachment of the main units 5 to the concrete body 4.
  • the various main units 5 all extend parallel to said longitudinal edge 6 in the same direction X.
  • the main units 5 are shaped so that the upper faces of the main units 5 are at substantially height of the upper face of the compression slab 14 intended to be cast on the pre-slab 1 as we will see later.
  • the main units 5 of the pre-slab 1 are all identical to one another and are all separated two by two by the same distance. Two successive main units 5 therefore define between they have a space at the longitudinal edge 6.
  • Each main unit 5 here comprises a base 10 shaped as an open container, for example of the flower box type.
  • Each base 10 is for example made of plastic material.
  • each base 10 includes a finger (not visible here) arranged on one of the outer side faces of said base 10 and extending longitudinally outward from the base 10, the finger being shaped to define the constant interval between two consecutive bases 10.
  • each main unit 5 comprises a block of thermally insulating material 7 which is received in the corresponding base 10.
  • Each block 7 is for example nested in the corresponding base 10.
  • the block 7 therefore here has a substantially parallelepipedic shape corresponding to that of the base 10.
  • Each block 7 is for example made of mineral wool.
  • the base 10 comprises means for retaining the associated block 7 in the base 10.
  • the retaining means comprise for example indentations provided in at least two of the internal faces of the base 10 and projecting inwards. of the base 10.
  • Each main unit 5 (formed in the present case of a base 10 and a block of thermally insulating material 7) thus forms a thermal breaker making it possible to treat the thermal bridge between the floor 2 and the wall 3 as we will see by the following.
  • the pre-slab 1 here comprises secondary units 8 of thermal insulation.
  • Each secondary unit 8 is here a specific concrete block having a reduced thermal conductivity of less than 1 watt per meter Kelvin.
  • the concrete specific to each secondary unit 8 is a concrete with a thermal conductivity of less than 0.6 watt per meter-kelvin, which further reinforces the treatment of thermal bridges by said secondary unit.
  • thermedia concrete (trademark registered by the company Lafarge) is used as concrete.
  • Each secondary unit 8 is arranged between two successive main units 5 of the pre-slab 1 so as to extend along the direction X.
  • Each secondary unit 8 is anchored in the concrete body 4. In this way, the pre-slab 1 presents parallel to its longitudinal edge 6 a continuous alternation of a main unit 5 and a secondary unit 8.
  • the secondary thermal insulation units 8 are arranged so as to coat the two respective main units 5 surrounding them. Each main unit 5 is thus anchored at its two outer side faces in two successive secondary units 8.
  • the secondary units 8 are arranged so as to protrude from the upper face of the concrete body 4.
  • the secondary units 8 are shaped so as to extend substantially further over the entire height of the pre-slab 1 (That is to say to the underside of the concrete body 4). This thus makes it possible to significantly reduce the thermal bridges between the floor 2 and the adjacent wall.
  • the secondary units 8 are arranged so as to protrude by the same height from the upper face of the concrete body 4 as the main units 5.
  • the secondary units 8 are therefore here shaped so that their upper faces are substantially up to the upper face of the compression slab 14 intended to be cast on the pre-slab 1 as we will see later.
  • the secondary units 8 further comprise sets of frames 9, each set of frames being arranged so as to pass through one of the secondary units 8 so that the frames of this set 9 project on either side of the associated secondary unit 8 for extend on one side towards pre-slab 1 above pre-slab 1 and on the other side towards wall 2 above at least part of the portion of wall 2 already built as we are we will see it later.
  • Each set of reinforcement 9 is therefore anchored in the concrete of the secondary unit 8.
  • the reinforcements of the sets of reinforcements 9 are for example made of steel.
  • the pre-slab 1 is thus arranged during the construction of the building.
  • the wall 3 is mounted up to substantially the level where the floor 2 is intended to be laid.
  • the upper part of the mounted wall portion 12 has a stop 13 which allows a better connection with the rest of the wall 3 to be built as we will see later.
  • beams are then positioned against the mounted portion 12 of the wall 3 so as to extend normal to said mounted portion 12 in order to serve as a support for the construction of the floor 2.
  • the pre-slab 1 is arranged on the beams to delimit the surface of the floor 2.
  • the longitudinal edge 6 of the pre-slab 1, thus forming here in part one of the edges of the floor 2, is placed on the mounted portion 12 of the wall 3 considered so as to extend parallel to the X direction.
  • figure 1 thus illustrates the already mounted portion 13 of the wall 3 and said pre-slab 1.
  • the compression slab 14 by pouring concrete on the pre-slab 1 so that the projecting reinforcements of the secondary units 8 are embedded in the concrete.
  • the compression slab 14 is cast so as to come level with the various main units 5 and the various secondary units 8 running along the wall 3.
  • Concrete is also poured above the already existing portion 12 of wall 3 to continue the construction of the wall 3 so that the frames projecting from the other side of the secondary units 8 (and which extend above the portion 12 of the wall 3 already built) are also embedded in the concrete.
  • the sets of frames 9 are thus anchored in the floor 2 and in the wall 3 which ensures the bearing capacity of the floor 2.
  • the bases 10, the main thermal insulation units 5 and the secondary thermal insulation units 8 together constitute a formwork portion of the compression slab 14 intended to be cast on the pre-slab 1.
  • formwork of the compression slab 14 is very simple.
  • the anchoring of the main units 5 to the secondary units 8 also makes it possible to ensure good formwork for the compression slab 14.
  • the thermal bridges likely to form between the floor 2 and the wall 3 therefore prove to be reduced here along the entire length of the wall 3 considered and over substantially the entire height of the floor 1.
  • the adjoining of the various secondary units 8 and the main units 5 makes it possible both to ensure good thermal insulation of the floor 2 at the level of the wall 3 and at the same time to ensure good bearing capacity of the floor 2.
  • the secondary units 8 also fulfill a role of structural support thanks to the concrete constituting them and also to the sets of reinforcements 9 which are anchored in these secondary units 8.
  • mineral wool for the 7 blocks of the 5 main units allows, in addition to the thermal insulation function, to perform an additional fire protection function as well as an additional sound insulation function .
  • the fixing bases 10 are arranged in a mold for manufacturing the concrete body 4 of the pre-slab 1 so that said bases 10 are positioned along one of the edges of the manufacturing mould, the edge therefore extending parallel to the direction X.
  • the different bases 10 are separated from each other by an identical predefined distance for all the bases.
  • the finger of each base 10 cleverly facilitates the correct arrangement of the different bases 10 in the manufacturing mold, which facilitates the work of the worker.
  • the bases 10 therefore rest on the bottom of the mold.
  • the space left free between two successive bases 10 is cased.
  • a first formwork element facing the edge of the mold and a second formwork element facing the future concrete body 4 are arranged, the two formwork elements therefore extending parallel to the direction X.
  • the two main units 5 and the two formwork elements define a substantially parallelepipedal volume.
  • the sets of frames 9 are arranged in the manufacturing mold.
  • the formwork elements comprise orifices adapted to allow the passage of the reinforcements through them or being shaped in the form of a comb for the passage of the reinforcements through them.
  • the formwork elements are for example shaped in the form of a plate.
  • the formwork elements are for example made of metallic material, for example steel, or even wood or plastic material. formwork elements are either reusable or lost items.
  • the concrete is poured into the manufacturing mould.
  • the specific concrete is then poured inside said volumes from above to finish filling said volumes and to form the secondary units 8 of thermal insulation.
  • the main units 5 here the bases 10 as well as the blocks 7) thus cleverly serve directly as formwork portions.
  • the two concretes are then allowed to set.
  • This makes it possible to anchor the bases 10 on the one hand to the concrete of the concrete body 4 of the pre-slab 1 and on the other hand to the specific concrete of the secondary units 8 of thermal insulation.
  • This also makes it possible to anchor the blocks 7 to the specific concrete of the secondary units 8 of thermal insulation (since the blocks 7 also serve as formwork portion for the formation of the secondary units 8).
  • this makes it possible to anchor the sets of reinforcements 9 to the secondary units 8 as well as to the concrete body 4.
  • the secondary units 8 are thus also found to be anchored to the concrete body 4.
  • the pre-slab 1 thus created and delivered to the site therefore proves to be very simple to handle and to move, which facilitates the task of the people working on the site.
  • the pre-slab 1 thus delivered already has everything integrated, both the structural support reinforcements and both the secondary and main thermal insulation units.
  • a second embodiment of the construction element according to the invention will now be described with reference to the picture 3 .
  • the elements in common with the first embodiment retain the same numbering increased by one hundred.
  • Each base 110 is again shaped into an open container, for example of the flower box type, of substantially parallelepiped shape.
  • each base 110 further comprises two additional walls: a first wall 121 extending in the extension of one of the longitudinal walls from a first external side face of the base 110 and a second wall 122 extending in the extension of the other of the longitudinal walls of the base 110 from the second outer side face of the base 110, each wall 121, 122 being shaped to define the constant interval between two consecutive 110 bases.
  • the bases 110 are arranged one after the other, their longitudinal walls 121, 122 make it possible to directly define the longitudinal formwork of the volume to be formed to create the secondary units 108 of thermal insulation. This eliminates the need for an additional formwork element for the manufacture of the pre-slab 101.
  • the longitudinal walls 121, 122 are adapted to allow reinforcement to pass through them.
  • the construction element may not be a pre-slab but for example a beam, a joist
  • the construction element was used for the treatment of thermal bridges between the non-load-bearing edge of a floor and the wall adjacent to said edge
  • the construction element could be used for the treatment of thermal bridges between a bearing edge of a floor and a wall adjacent to said edge.
