The present invention relates to a carrier element (1) for building of an arch structure which has a plurality of segments (2) arranged side by side in a longitudinal direction (L), wherein each segment (2) has a centre region (3) and two side regions (4, 5) extending to different sides (6, 7) from the centre regions (3) and separated from the adjacent segment (2) by a cut (8) extending substantially along the entire width of the centre region (3), wherein two adjacent segments (2) are connected by a common for them side region (4) at a first side (6) and separated by a side cut (10) separating from one another adjacent side regions (5) at a second side (7) and one of said two segments (2) and another next to it segment (2) in the longitudinal direction are connected common for them side region (5) at a second side (7) and separated by the side cut (10) separating one from another adjacent side regions (4) at a first side (6), so that connection and separation points of the side regions (4, 5) are altering from side to another opposite its side (6, 7) along the longitudinal direction (L) from segment (2) to segment (2). The invention is characterized in that for facilitating forming of an arch with the carrier element at least one bore (11, 12, 13) is arranged in the centre region of each segment (2) between two side regions (4, 5) adjacent to the side cut (10). |
