摘要

Mold for forming a material having a surface that deforms under the action of tie rods and a flange, and a formwork system using said mold A mold (1) is proposed for forming a material during its hardening comprising a deformable surface (2; 3), a first face of which is intended to come into contact with said material in a fluid form, and at least two attachment points. (6) secured on the second face, each of the at least two fixing points (6) is attached by a first pivot connection (7) to one end of the tie rod (8), each other end of the tie rod being connected to a rotating flange (9) by a second pivot connection (10), the rotation of said flange causing a displacement of the position of the first pivot connections and a modification of the distance between these first pivot connections triggering a deformation of the flatness of said surface (2) ; 3). In this way, the mold can produce surfaces of different shapes, which will be reproduced by the material after it has hardened. Abstract figure = figure 1
