Definitions

  • the present invention relates to an insulation device for a floor with beams, comprising at least one part made essentially of at least one thermally insulating material and defining in the upper part an end-interlocking interjoists arranged to bear on two adjacent beams resting on their ends on supporting elements of the floor and in the lower part an insulating wall extending vertically under said interjoists end to a predetermined height.
  • this type of beam floor may include interjoists made of insulating materials such as for example expanded polystyrene or the like.
  • the thermal insulation is interrupted to the right of the load-bearing elements of the construction, such as external walls, interior walls commonly called the walls of split usually arranged in crawl spaces and basements, beams, etc., on which the ends of the beams rest.
  • these bearing elements are not insulated, they constitute an important thermal bridge.
  • the solution commonly implemented is to isolate these carrier elements by fixing, by various means such as gluing, mechanical fastening, etc. insulation plates cut on site to the appropriate dimensions. This insulation process is a traditional process, time consuming and difficult to achieve, especially in the case of floors above sanitary crawl spaces since the underside of the load-bearing elements is difficult to access.
  • a solution was developed by the applicant and was published FR 2 916 212 . It proposes a specific end interjoists extended in the lower part by an L-shaped covering skirt arranged to cover the lateral face and the bottom of the adjacent supporting beam on which the beams rest. In this way, the carrier beam can be fully insulated by the skirts of two overlapping interjoists arranged opposite opposite sides of this beam. Nevertheless, this solution is limited to the supporting beams and does not extend to the walls, in particular to the walls of slitting. In addition, this solution is fixed and is not adaptable to the different dimensions of the carrier beams, especially in height and width. In this case, it is necessary to provide for the manufacture of several models of end interjoists in order to be able to meet all the dimensions of existing load-bearing beams, which complicates and increases the management of production, stocks and transport.
  • the publication EP 2,055,848 discloses a thermal breaker for interposing between a floor and an outer wall, in the form of an insulating interjoists known from the prior art, the lower part comprises a tongue extending horizontally to cover the sole of the an adjacent beam.
  • This thermal breaker is designed to achieve horizontal insulation under floor, that is to say under the beams of the floor which carry the interjoists to the right of the load bearing walls by pressing against their inner face on a height limited by the height of the tongue.
  • This solution is therefore not satisfactory for effectively isolating the load-bearing walls and is not extensible to the supporting beams.
  • the present invention aims to solve this problem by proposing a finished, ready-to-install, universal and modular insulation device, making it possible to effectively isolate all types of load-bearing elements, both external walls and slotted walls, as well as supporting beams of different dimensions, with the aim of providing optimal solution to meet the constraints imposed by current and future thermal regulations.
  • the invention relates to an isolation device as defined in the preamble, characterized in that said insulating wall comprises on said lateral overlap zone at least one horizontal groove arranged to receive, by interlocking, a longitudinal edge of said zone d breakable end when it is detached from the rest of the insulating wall, so that said breakable end zone is arranged either to remain in the extension of said lateral covering area when the carrier element is a wall, or to be detached and to be bonded to said lateral overlap area to form a bottom cover of the underside of the carrier member, when the carrier member is a beam.
  • the same insulation device can cover at least part of the side wall of a load-bearing wall, but also the side wall and the bottom of a load-bearing beam.
  • the insulating wall may advantageously comprise a plurality of horizontal grooves arranged at different heights corresponding to different heights of carrying beams.
  • This insulating wall may comprise on the other side of its lateral overlap zone, at least one horizontal marking defining a cutting zone located under a horizontal groove. It may also include several, the number of horizontal markings may be equal to the number of horizontal grooves.
  • the breakable end zone comprises on its longitudinal edges a stepped shape defining at least one raised portion and a recessed portion, the thickness of the raised portion corresponding to the height of said horizontal groove.
  • this breakable end zone may comprise on its lateral edges complementary interlocking shapes with the lateral edges of the breakable end zone of other adjacent insulating devices to ensure the continuity of the thermal insulation.
  • the insulating wall advantageously comprises on its lateral edges forms of complementary interlocking with the lateral edges of the insulating wall of other adjacent insulating devices.
  • the interjoists end disposed in the upper part of the device comprises on one of its sides for leaning on a beam a cover tongue for covering the underside of said beam.
  • the insulating wall extends under said end interjoists and under its cover tongue.
  • the device of the invention can be made from at least two materials having different properties.
  • at least a portion of the insulating wall may be made of a material having thermally insulating properties greater than those of the material constituting the remainder of said device.
  • the isolation device 10 for floor 1 with beams which comprises a set of beams 2 parallel to each other resting at their respective ends on bearing elements 4, 5, 6 of a construction, and a set of interjoin 3 respectively disposed between the adjacent beams 2 to fill the T-bays of the floor 1 delimited by said adjacent beams 2, building on them.
  • This bearing structure is a lost formwork adapted to receive a metal frame and poured concrete to form the compression slab of the floor.
  • the beams 2 may be made of reinforced concrete or not, prestressed or not, or any similar product.
  • the interjoists 3 can be made of any material known for this type of product, such as concrete, cellular concrete, composite materials based on plant fibers, thermally insulating materials such as expanded polystyrene, or the like.
  • the load-bearing elements of the construction may be known in the known manner an outer wall 4 or peripheral, an inner wall or shear wall 5, a beam 6, or the like.
  • the insulation device 10 of the invention consists of at least one part made essentially of at least one thermally insulating material, such as, for example, expanded polystyrene or any other equivalent material. It defines in the upper part a interjoin said end interjoists 11 arranged to rest on two adjacent beams 2 at the ends of a span T facing at least one of the carrier elements 4-6 of the construction.
  • This end interjoists 11 has as all known interjoists, at least two lateral flanges 12 adapted to bear on the heel of the beams 2 and a cover tongue 13 extending laterally from one of the side edges to cover the underside of the beam 2 on which the corresponding lateral rim 12 rests.
  • This end interjoists 11 also has a lateral support 20 disposed under the free lateral edge 12, adapted to rest on a structural load-bearing element, such as an exterior or peripheral wall 4.
  • the insulation device 10 comprises in the lower part an insulating wall 14 extending vertically under the end interjoists 11 to a predetermined height H arranged to cover at least part of the carrier element 4-6 opposite. of which he is disposed.
  • This insulating wall 14 is therefore in the extension of the end interjoists 11 and has a substantially flat lateral face intended to be pressed against a lateral face of the corresponding carrier element 4-6. It may have a constant thickness and equal to that of the interjoists end 11 according to the illustrated embodiment. It may also have a widened thickness constant or increasing downwards, to offer if necessary an insulation thickness greater than that of the interjoists end 11.
  • the insulating wall 14 makes it possible to cover the corresponding lateral wall of the slitting wall 5 on said height H, which corresponds at least to the prescriptions of the thermal regulation in force where the height H is for example equal to 60 cm.
  • This insulating wall 14 comprises a lateral overlap zone 15 followed by a structured breakable end zone 16 (cf. Fig. 1A and 1C ).

  • this breakable end zone 16 can form a bottom cover of the underside of the carrier element, when this carrier element is a beam 6 (cf. Fig. 3-5 and 7 ).
  • the three horizontal grooves 17 are arranged at three different heights H1, H2, H3 corresponding to three different heights of existing carrier beams 6, namely a flat beam 61 (cf. Fig. 3A ), a middle beam 62 (cf. Fig. 4A and 7 ) and a high beam 63 (cf. Fig. 5A ).
  • a flat beam 61 cf. Fig. 3A
  • a middle beam 62 cf. Fig. 4A and 7
  • a high beam 63 cf. Fig. 5A
  • the worker can by means of a conventional cutting tool such as a saw, cut the insulating wall 14 by following the horizontal marking 18 to adapt the height of the isolation device 10 to the carrier element 4-6 to isolate as shown in FIGS. FIGS. 3B, 4B and 5B .
  • the breakable end zone 16 has on its longitudinal edges complementary step-shaped interlocking shapes defining at least one raised part 16a and a recessed part 16b, the thickness of the raised part 16a corresponding to the height horizontal grooves 17 to allow assembly by interlocking without gluing or other fastening means. Any other form of complementary nesting may also be suitable.
  • the side edges of the breakable end region 16 have complementary step-like interlocking shapes 16a, 16b, so that the side edges of the adjacent breakable end regions 16 overlap to provide continuity. thermal insulation both along a supporting wall 4, 5 and under a carrying beam 6.
  • the insulating wall 14 also has on its lateral edges complementary interlocking shapes 19 to ensure the continuity of the thermal insulation by interlocking the side edges of insulating walls 14 of adjacent insulation devices 10.
