<p>The construction element (1) has a hollow body (2) which extends along a longitudinal axis (A) and has substantially rectangular cross-section, possibly with rounded corners, and at least a first (3a) and at least a second (3b) strut element, wherein the first strut element (3a) extends from a first edge of the hollow body (2) to the second edge which lies opposite it with respect to the longitudinal axis, and the second strut element (3b) extends along the other diagonal between the associated edges. The strut elements (3a, 3b) are advantageously designed and arranged such that they absorb compressive forces but not tensile forces. A semi-finished product (1a) which has the strut elements (3a, 3b) and a tubular sleeve element (4) which extends along a longitudinal axis (A) can be arranged inside the construction element (1). The hollow body (2) and the strut elements (3a, 3b) can be fabricated completely from a fiber-reinforced plastic. A surface element (5) is also shown which has a plurality of construction elements (1) according to the invention which are arranged next to one another and are arranged between two cover elements (6, 8) in a filling compound (7). Such surface elements (5) can, for example, be used as floor or roof elements, especially when particularly high bearing capacity to dead weight ratios are required. Methods for producing the construction elements (1) and the surface elements (5) are also proposed.</p> |
