Adjustable arrangement allowing shuttering/formwork panels to be wedged in the correct position for forming the walls of a structure without problems over time. The invention concerns a nailable arrangement consisting of a component 1 with female racks in which the male rack of the component 2 engages. The whole assembly is completed by two conical connection pieces, components 3, which are held in position at the ends of the components 1 and 2 by a keyed cylindrical part. These components 3, withdrawn after removal of the formwork from the walls, are replaced by concrete, thereby ensuring that the structure conforms to the technical specifications (no disordering over time). For walls of great thickness, it is envisaged to use two components 1-2 spaced apart a good distance by components of variable length made of plastic material injected into a mould or by simple tubes of variable length. the arrangement according to the invention is intended for the construction of walls made of shuttered concrete in the building industry and in civil engineering works. <IMAGE>
