is proposed, inter alia, a hohlprofiltru00e4ger (2) with at least one verstu00e4rkungsblech (8) which is arranged within the hollow section (3) and the same is attached.it is beneficial to at least one verstu00e4rkungsblech (8) by a length of hollow section (3) run plattenfu00f6rmiges basisblech (9) is formed, which through the profilgrund (4) of the hollow section (3) can be the first longitudinal edge (10) on the profilgrund (4) abgestu00fct zt and the same is attached.the basisblech (9) has a first longitudinal edge opposite the said (10) in a longitudinal direction of the hollow section (3) a majority in a row command and the basisblech (9) on the other side, alternately, and due to flanschabschnitte (11, 12, 13), each with egg a free second longitudinal edge (14).the flanschabschnitte (11, 12, 13) by means of the second longitudinal edge (14), each at a profilwand (5, 6) of the hollow section (3) supported and fixed.
