Described is a lattice girder with at least one longitudinal rod (2) as the upper chord and at least one reinforcing bar (1) as the lower chord. Lateral struts (3) which originate at the lower chord and converge on the upper chord are welded to a longitudinal rod of the upper chord at two points spaced a certain distance apart. The top ends of the lateral struts (3) are bent outwards, from the plane of the struts, to form a loop (5). |
