Definitions
- the present invention relates to a reinforcing device for a building element of a building.
- This invention also relates to such a construction element of a building and a method of building a building implementing such a reinforcing device.
- This invention relates to the field of the building and, more particularly, that of the parts used in the construction of a building, more specifically that of the reinforcing pieces intended to stiffen such a building and / or to connect together two elements of construction that includes such a building.
- building elements that can, then, take the form of a foundation, a slab, a wall, including a precast wall.
- Such a construction element then comprises, on the one hand, a concrete base and, on the other hand, at least one waiting frame extending partly inside this base and partly outside. of this base, this from this base and, in particular, vertically.
- Such a pending frame usually adopts the shape of an iron which usually extends vertically and which has a free end likely to cause injury to operators involved in a construction site.
- This solution consists of deforming the iron of the armature so as to give its free end a curved shape, especially in a loop.
- the presence of such a loop is not allowed in a construction seismic zone so it should be deleted.
- Such deletion is ensured by cutting such a loop, this during a long and tedious operation, requiring special tools and the intervention of an operator. This operation must be ensured before placing the precast wall and leads, for a certain time at least, the appearance of irons whose free end is, again, likely to cause injury.
- the present invention is intended to overcome the disadvantages of the armature devices of the state of the art.
