摘要
The arch vault (1) comprises an elongated mid-section (6) and one side element (3,4) consisting of a prefabricated reinforced concrete element. The side element is raised along a lower edge (5) and arranged against the mid-section to form an arch section (7) through interaction at its upper end part or edge (8). Only the mid-section is intrinsically anchored in the limiting surface (2a) of the space (2), that the side element is arranged aloof from and entirely freestanding from the limiting surface between its lower and its upper end part or edge , which upper end part or edge is releasably connected with the mid-section via a joint (25) and that the mid-section constitutes a support for the side element. An independent claim is also included for.
