<p>The grating has two transverse bars (3) providing horizontal supporting distances. Bars (2) are accommodated in slots that have u-shaped circumferential contours. Prefabricated form-slots (4) are provided in an area of two side wall surfaces (6, 7) that define an accommodation space (5), where the surfaces have form-projections (F, F`) that cover the bar, which is inserted in the form slots, in a force and/or form-fit manner. The projections are projected over a partial area of the side wall surfaces and are formed for an upper edge and for base wall of the form slots.</p> |
