Abstract (en)
[origin: US4529567A] The invention relates to an apparatus and method for manufacturing concrete structural elements. In order to manufacture the elements, setting of the concrete takes place in a casing (1), while the concrete is compressed with an axial pressure of at least 50 MPa and the casing is surrounded with a hoop (2,3) so as to create transverse planes of pressure.
Abstract (fr)
L'invention concerne des éléments de structure en béton. Pour fabriquer les éléments, on réalise la prise du béton dans une enveloppe (1) tout en comprimant le béton avec une pression (7) de la gamme 50-150 MPa et en entourant l'enveloppe d'une frette (2, 3) pour que l'enveloppe résiste à la poussée du béton pendant la compression. Application à la fabrication d'éléments de structure.
