<p>A method for making a truss (1) comprising a wall (2) and a roof (3) integral with each other and together forming a specific obtuse angle. This method, which is of the type which consists in producing the wall and the roof against the outer surfaces of the two faces (4, 5) of a dihedron with a vertical edge (6), disposed on a horizontal plane (7), is characterised in that, before producing the truss, a first face (4) of the dihedron is rotated about the vertical edge (6) until it forms the specific angle with the second face (5), and in that, after the production of the truss, the truss (1) is momentarily secured against the second face (5), the two faces (4, 5) are detached from each other, the second face (5) is pivoted with the truss (1) outwards about a horizontal axis (8) until the truss (1) attains a flat position on an independant platform level, the truss (1) is separated from the second face (5), the latter is pivoted in the opposite direction until it attains the initial position and the two faces (4, 5) are recoupled. The invention relates also to a gauge for implementing this method. <IMAGE></p> |
