Arch vault (1) for lining of or for vaulting inside spaces (2) as tunnels, rock chambers or similar, which arch vault (1) comprises at least one elongated mid-section (6) and one side element (3, 4), which side element (3, 4) consists of a prefabricated reinforced concrete element and which side element (3, 4) is raised along a lower edge (5) and arranged against the mid-section (6) to form an arch section (7) through interaction at its upper end part or edge (8). According to the invention, only said mid-section (6) is intrinsically anchored in the limiting surface (2a) of the space (2), that the side element (3, 4) is arranged aloof from and entirely freestanding from said limiting surface (2a) between its lower and its upper end part or edge (5, 8), which upper end part or edge (8) is releasably connected with said mid-section (6) via a joint (25) and that said mid-section (6) constitutes a support for the side element (3, 4). |
