Abstract

Un module de stockage (MS) comprend : - des cellules de stockage (CS) parallèles et encadrées par des première (PE1) et seconde (PE2) plaques d’extrémité traversées par des tirants (TM) et définissant un premier écartement entre elles par un vissage d’écrous (E1), - une plaque intermédiaire (PI) traversée par les tirants (TM), intercalée entre la seconde plaque d’extrémité (PE2) et la dernière cellule (CS) et comprenant une face avant (FV) à laquelle sont solidarisés N goujons (G) traversant N trous traversants de la seconde plaque d’extrémité (PE2), - des ressorts (R) intercalés entre les seconde plaque d’extrémité (PE2) et plaque intermédiaire (PI) en étant initialement comprimés pour exercer sur cet dernière une pression fixée par un vissage d’écrous (E2) sur les goujons (G) et transmise aux cellules (CS), ces écrous (E2) étant ensuite retirés pour laisser la plaque intermédiaire (PI) libre de se translater en fonctionnement. Figure 1A storage module (MS) comprises: - storage cells (CS) parallel and framed by first (PE1) and second (PE2) end plates crossed by tie rods (TM) and defining a first distance between them by a screwing of nuts (E1), - an intermediate plate (PI) crossed by the tie rods (TM), interposed between the second end plate (PE2) and the last cell (CS) and comprising a front face (FV) to which are secured N studs (G) passing through N through holes of the second end plate (PE2), - springs (R) interposed between the second end plate (PE2) and intermediate plate (PI) being initially compressed to exert on the latter a pressure fixed by screwing nuts (E2) on the studs (G) and transmitted to the cells (CS), these nuts (E2) then being removed to leave the intermediate plate (PI) free of to translate in operation.
