Title (EN) METHOD FOR PRODUCING SHELLS WHICH ARE CURVED ONCE AND SHELLS WHICH ARE CURVED TWICE
(FR) PROCÉDÉ PERMETTANT DE PRODUIRE DES COQUES À SIMPLE COURBURE ET À DOUBLE COURBURE
(DE) VERFAHREN ZUR HERSTELLUNG VON EINFACH GEKRÜMMTEN UND ZWEIFACH GEKRÜMMTEN SCHALEN
Abstract:
(EN) The invention relates to a method for producing shells (1) which are curved once and shells (10) which are curved twice, having the following steps: producing shells segments (2, 20) under controlled conditions, preferably in a prefabrication plant; pre-fracturing the shells segments (2, 20) by means of a fracturing device (5) under controlled conditions, preferably in the prefabrication plant, and transporting the pre-fractured shell segments (2, 20) to a construction location; placing a tire on a base surface (7), preferably a flat base surface; placing and arranging the shell segments (2, 20) on the tire; arranging at least one flexible tension member on opposite lateral edges (9) of a base surface (8) of the shell (1) curved once or on an outer edge (19) of the base surface (80) of the shell (10) curved twice in the circumferential direction; and carrying out a shaping process, i.e. lifting and curving the shell segments (2, 20) by blowing air into the tire and/or under a tensile load of the at least one tension member.
(FR) L'invention concerne un procédé permettant de produire des coques (1) à simple courbure et des coques (10) à double courbure, le procédé consistant à : produire des segments de coque (2, 20) dans des conditions contrôlées, de préférence dans une usine de préfabrication ; précasser les segments de coque (2, 20) au moyen d'un dispositif de rupture (5) dans des conditions contrôlées, de préférence dans l'usine de préfabrication, et transporter les segments de coque (2, 20) précassés jusqu'à un site de construction ; placer un pneu sur une surface de base (7) de préférence plane ; placer et agencer les segments de coque (2, 20) sur le pneu ; agencer au moins un organe de traction souple sur des bords latéraux opposés (9) d'une surface de base (8) de la coque (1) à simple courbure ou dans la direction périphérique sur un bord extérieur (19) de la surface de base (80) de la coque (10) à double courbure ; effectuer le processus de façonnage, c'est-à-dire relever et courber les segments de coque (2, 20) par insufflation d'air dans le pneu et/ou par sollicitation en traction dudit au moins un organe de traction.
(DE) Das Verfahren zur Herstellung von einfach gekrümmten Schalen (1) und zweifach gekrümmten Schalen (10) umfasst: Herstellen von Schalensegmenten (2, 20) unter kontrollierten Bedingungen, vorzugsweise in einem Fertigteilwerk; Vorbrechen der Schalensegmente (2, 20) mittels einer Brechvorrichtung (5) unter kontrollierten Bedingungen, vorzugsweise im Fertigteilwerk, und Transportieren der vorgebrochenen Schalensegmente (2, 20) zu einer Baustelle; Auflegen eines Pneus auf einer, vorzugsweise ebenen, Grundfläche (7); Auflegen und Anordnen der Schalensegmente (2, 20) auf dem Pneu; Anordnen zumindest eines flexiblen Zugglieds, an gegenüberliegenden Seitenrändern (9) einer Basisfläche (8) der einfach gekrümmten Schale (1) oder in Umfangsrichtung an einem äußeren Rand (19) der Basisfläche (80) der zweifach gekrümmten Schale (10); Durchführen des Formgebungsprozesses, also Anheben und Verkrümmen der Schalensegmente (2, 20) durch Einblasen von Luft in den Pneu und/oder unter Zugbelastung des zumindest einen Zugglieds.
