Abstract

A comb beam (A) which consists of at least one sequence composed of a straight zone (1) and a groove zone (2) with a length equal to n * the thickness of the beam (A), where n is the number of beams (A) adjacent to each other, and with a depth equal to half the height of the beam (A), the beam (A) ending with half-grooves (3) with a length equal to n / 2 * the thickness of the beam, where n is the number of beams (A) adjacent to each other, and with a depth equal to half the height of the beam. The invention also concerns a structural element and a load-bearing core which use this comb beam.
