The invention relates to a point-supported element or flat concrete ceiling (BD) that comprises a transverse force and punching reinforcement (B) into which a lattice beam (1) that tapers on a support vertical axis (A) is integrated, wherein the lattice beam comprises lower chords (U) and a continuous upper chord (O) or anchoring elements (10) arranged with open spaces (Z) between one another and at least one serpentine diagonal strut section (D) with upper and lower bent portions (11, 12) between each two successive diagonal struts (S1, S2), said bent portions being secured in securing points (SO, SU). The diagonal struts (S1, S2) are angled in the same manner upwards and in the direction of the support (T). The diagonal strut (S1) nearest to the support is inclined at a steeper angle (α)<90° relative to the lower chords (U), and the preceding diagonal strut (S2) further from the support is inclined at an angle, which is flatter by at least 10°, of 45°≦(α2)<90° such that, of the concrete anchoring zones (VO, VU) formed by the diagonal strut (S1) nearest to the support, the upper concrete anchoring zone (VO) lies closer to the support vertical axis (A) than the lower concrete anchoring zone (VU).
