The new Hamburg market

Abstract

This article deals specially with the parking hall, the unloading platforms, the railway network, the underground cooling chambers and the ancillary services which make this a most modern market; and a source of pride to Hamburg. The roof structure is of special interest, and consists of a reinforced and prestressed concrete shell, of undulated outline. The synclines are suspended, and the anticlynes of the shell contain skylights. The nave is subdivided into five longitudinal sections, three of them 48 m in span and two intermediate ones, of 16 m width; The arches covering the three main sections are interconnected with slightly arched elements, which provide great stiffness to the whole roof structure. The construction of this roof was done in stages of 20 m length each, and 180 m width, and advanced progressively along the 220 m length of the nave. Each stage took 2 months to complete, and in this time the infrastructure of the next stage was prepared. Work was done with the aid of modern construction machinery, and this made it possible to mechanise most of the operations, and employ a small number of operators.
