Device for limiting the relative movement of two elements of a civil engineering structure and structure including said device

DETAILED DESCRIPTION The device of the invention can be placed in the structure when the latter is in the course of being constructed or at a subsequent stage with the aim of strengthening the structure.
The object of the invention is to improve known devices so as to provide an extremely simple device to be embodied and able to mass produce.
Apart for its substantial reduction of the production costs, another objective of the invention is to provide a device easy to use including in existing structures.
To this effect, the device of the invention comprises: at least one portion able to undergo a plastic deformation at the time of the relative movement of the two elements of said structure, means for guiding the plastic deformation of the portion able to undergo a plastic deformation, the portion able to undergo a plastic deformation and the guiding means forming a single piece element.
Thus, the invention provides a device embodied in a single piece which resolves the problem of positioning the various portions of the device in relation to one another and simplifies the production method.
According to the invention, the portion able to undergo a plastic deformation includes at lease one bar, preferably with a rectangular section linked to the means for guiding the plastic deformation at the level of one of its extremities, and the means for guiding the plastic deformation include at least one curving template defining at lease one curved surface on which the portion, able to undergo a plastic deformation during said deformation folds.
The invention also concerns a device including several identical superimposed single piece elements.
The device may also include at least one support element fixed to at least one template and having one portion of its surface adjacent to at least one bar, said support element being intended to limit tilting of the device during deformation of said device.
According to a first embodiment, the device of the invention includes a plurality of bars placed approximately parallel to one another inside a given plane between two approximately parallel straight lines
