CONSTRUCTION SET FOR THE REALIZATION OF A PREFABRICATED TWO-LAYER CHASSIS SUITABLE TO BE ASSEMBLED ON SITE AND PROCESS FOR MAKING SUCH A CHASSIS

摘要

The invention relates to a construction assembly for producing a segment formed of an internal layer called the intrados and an external layer called the extrados, the construction assembly being characterized in that it comprises a first and a second. concrete parts (1, 2), distinct from each other, intended to form the lower surface and upper surface of the segment, respectively, the second part (2) being made of compressible concrete, and assembly means (4) making it possible to assemble the second part (2) on the first part (1), said assembly means (4) being configured to allow lateral displacement of the second part (2) relative to the first part ( 1) when said parts are assembled together under the action of a shear stress on the second part (2). The invention also relates to a segment made from such a construction assembly and its production process. Figure to be published with the abstract: Fig. 1
