Definitions

• the present invention relates primarily to the field of buildings and structures. It relates more particularly to the field of formwork, and more generally to any field for which an empty volume must be filled with a filling, this filling being a mixture of solid materials and a fluid.
• a filling can be a concrete, consisting of a mixture of aggregates of different sizes, cement and water.
• the invention particularly relates to the production of prefabricated assemblies for the production of structural webs to include an insulation on one side.
• thermal insulation 20 to 30 cm minimum .
• This insulating complex must generally be covered by a finishing and protection siding.
• the weight of this facing (between 100 and 200 kg / m 2 ) must be transmitted to the supporting structure. It is very easily understood that the greater the thickness of the insulation, the greater the moment exerted by the facing on the structure is, and more this connection is difficult to achieve.
• insulations smaller than 10 cm it is traditionally possible to directly fix the insulation on the structure by means of nails of horizontal axis which are pegged to the structure and have a thermal break device.
• the value of the moment, and therefore of the forces to be resumed is high, which leads to expensive and unsustainable implementations because of the increased risks of creep of the fasteners under high forces. .
• the insulation is installed after the construction of the outer sails.
• pegs are placed on the outer sails.
• Five brackets are usually used per square meter and four pegs per square.
• the wings dimension of these brackets is much greater than the thickness of the insulation; They perforate the insulation which is itself locked by a device, wooden or metal, itself fixed on the brackets.

• This aspect is reinforced by the filtering nature of the filtering wall which makes it possible to lower the value of the hydrostatic pressure during the filling of the structural volume and limits the risk of compromising, by compression, the insulation characteristics of the insulation.
