Definitions

• the external or exterior wall which is to say the wall that is to be on the outside of the building built with such panels, is made from a high-performance fibre-reinforced or reinforced concrete characterized by a high compression strength, which is to say one in excess of 100 MPa.
• a high-performance fibre-reinforced or reinforced concrete characterized by a high compression strength, which is to say one in excess of 100 MPa.
• Such concrete makes it possible to reduce the thickness of this external wall to a few centimetres.
• the invention relates to a reinforced-connection member joining a concrete wall and a connector, which member is intended to be embedded in the concrete wall, has a main axis and comprises:
• an anchor plate having an external planar face intended to face the exterior face of the concrete wall, and • a housing body projecting from the anchor plate on the opposite side to its external face, which housing body comprises a through-housing for receiving an end portion of the connector which extends along the main axis of the connection member and which opens onto said external face, and fixing means for fixing said connector end portion in said through-housing.
• the reinforced-connection member may also comprise the following optional features considered alone or in any technically possible combinations:
• the reinforced-connection member comprises distance-maintaining elements for keeping the anchor plate distant from the exterior face of the concrete wall, which distance-maintaining elements project from the external face of said anchor plate.
• the anchor plate comprises two flanges which extend one on each side of the housing body and of the main axis of symmetry, and the smallest width of each flange is at least equal to the width of the through-housing.
• the anchor plate comprises at least two symmetrical feet which extend one on each side of the housing body from said housing body.
• Each foot has at least one through-opening.
• the housing body has a U-shaped cross section, and the fixing means formed at the through-housing are means of attachment through elastic engagement.
• the invention also relates to a reinforced-connection device for a building panel of the sandwich panel type, comprising a connector of wavy shape comprising a plurality of peaks and at least one reinforced-connection member as described hereinabove arranged at a peak, which forms a connector end portion fixed in the housing of said connection member.
• the reinforced-connection device may also comprise the following optional features considered alone or in any technically possible combinations:
• the connector is made of composite material.
• the anchor plate 24 comprises four feet 7 which extend in pairs on each side of the through-housing 5 and symmetrically with respect to the two axes of symmetry X and Y, again in order to conform to the distribution of forces at the connections between the connection devices 1 1 and the relevant concrete wall 2. More specifically, the feet extend from the four corners 26 of the respective flanges 13.
• each foot 7 comprises a reinforcer 22 perpendicular to the plane defined by the axes X and Y, which reinforcer 22 is secured to the through-housing 5 and to the internal face of the relevant leg 7, these reinforcers 22 improving the stiffness of the legs 7.
• each opening 8 is delimited by the relevant corner 26 of the relevant flange 13, the edge of the relevant disc 23 and the lateral edges 27 of the foot 7, one of said lateral edges 27 being secured to the relevant reinforcer 22.
• the anchor plate 24 has a planar external face 9 parallel to the plane defined by the axes X and Y.
• the connection member 1 comprises a plurality of positioning elements 10 for positioning the connection member 1 in the relevant concrete wall 2, which elements 10 are conical projections projecting from the planar external face 9 of the anchor plate 24.
• all these positioning elements 10 are identical and the same size.
• each connector 3 concerned is fixed to at least one reinforced-connection member 1 . More specifically, the connector portions 6 comprising the peaks are inserted into the housings of the housing bodies 4 of the relevant connection members 1 and fixed into said housings 5 by elastic engagement. At the end of this step, a plurality of connection devices 11 has been created.
• connection devices 11 are placed in the bottom of a concrete mould. More specifically, the planar external faces 9 of the anchor plates 24 of the connection members 1 of each connection device 11 face towards the bottom of the mould, and the positioning cones 10 are in bearing contact against the bottom of the mould.
• connection devices 11 that are set in the external concrete wall 2 to form an exterior portion of the building panel 18 are obtained.
• a layer 16 of insulation is placed against the internal face of the concrete external wall 2. Those parts of the connectors that are not embedded in the external wall 2 are thus inserted into the layer 16 of insulation, with the exception of the free peaks 14 of said connectors 3.
• the exterior panel portion 18 is placed in a second mould, with the free peaks 14 of the connectors 3 in bearing contact with the bottom of this second mould.
• the reinforced-connection member 1 and the connection device 1 1 of the invention thus make it possible to create concrete building panels 15 of the sandwich panel type that are particularly well able to withstand the pull-out forces and shear forces experienced by the connectors 3, even when the concrete wall or walls 2 of the panel 15 are of small thickness, typically of the order of 3 centimetres thick.
• the reinforced-connection member does not necessarily have an axis of symmetry, but may simply have a main axis forming, for example, the longitudinal axis of said reinforced-connection member according to the invention.
