Description

The present invention relates to a device for connecting a

  first and a second wall used in the composition of a wall, including a structural wall formwork integrated.

  This invention relates to the field of structural walls with integrated formwork, more particularly the field of manufacture of the elements used in the composition of such a wall.

  In a manner known per se, such walls comprise a first wall, intended to be oriented towards the interior of the building receiving such a wall, and a second wall intended, as the case may be, to be directed outwards or towards inside this building. Within such a wall, these two walls are positioned facing one another, substantially parallel and at a distance from one another. These two walls are made integral with each other by means of a plurality of connecting devices, usually called connectors, and adopting the shape of a rod having two ends, one of which is centered in the concrete constituting the first wall while the other is embedded in the concrete constituting the second wall.

  It will be observed that all these connectors ensure, on the one hand, the appropriate positioning of one wall relative to the other and, on the other hand, the integrity of the wall, more particularly during the handling operations ( in the workshop and on site) and on-site and during any filling operations, by concrete, the spacing between these walls.

  To do this, such a connector is usually made of a metallic material, more particularly steel.

  In this respect, it will be observed that such a material has a very high thermal conductivity creating, between the two walls, a thermal bridge. The existence of this thermal bridge has the effect that the heat and cold are transmitted very quickly between the two walls through the connectors, such a transmission being all the faster as the number of connectors is high.

  The present invention is intended to overcome the disadvantages of state of the art connection devices.

  In this respect, it will be observed that a first embodiment consists in that the third element is constituted by a rod comprising, at each of its ends, a male part intended to cooperate with a female part that comprises said first element. as well as said second element.

  A second embodiment consists in that the third element consists of a tube comprising, at each of its ends, a female part intended to cooperate with a male part that includes said first element and said second element.

  In fact the male and female parts cooperate for fastening by screwing, by tight fitting, by gluing, by molding or by stamping.

  According to the first embodiment, the means for achieving a thermal break between the first and second walls consist in that the second element, respectively the first element, is made of a material having a thermal conductivity lower than that of the first. element, respectively of the second element.

  According to the second embodiment, the means for effecting a thermal break between the first and second walls consist in that, on the one hand, the first and second elements are mounted at a certain distance from one of the another within the third element and, secondly, this third element is made of a material having a thermal conductivity less than that of the first and second elements.
