For military as well as for civil applications there is provided a construction element comprising a disc-shaped central part (1) with at least four legs (2) extending outwards substantially radially with respect to a transversal axis (3) of the central part (1) and having longitudinal axes arranged in a plane perpendicular to the transversal axis (3) of the central part (1). The central part (1) has a face recess (4) extending inwardly from the central part (1) periphery between two adjacent legs (2). The face recess (4) has a width corresponding to the central part thickness and a depth being equal from one to two thirds of the central part width measured along an axis (8) of the face recess (4). The central part (1) is also furnished with a first passage (5) the axis (6) of which is parallel to the transversal axis (3) of the central part (1), and with a second passage (7), opening into the central part (1) face walls and having an axis (9) perpendicular to the axis (8) of the face recess (4). Each leg (7) includes a mounting duct (12) opening into both opposite front surfaces of the leg (7). |
