摘要
The present invention relates to a screening panel (4) comprising plastic screening elements (5), which are arranged next to each other and which are detachably fixed to steel profile sections (3) of a supporting structure by means of a separate profiled section (11) made of plastic and mounted in-between the screening elements (5). The plastic profiled section (11) and the screening elements (5) have corresponding engaging profiles (12, 13; 14, 15), which are held in a positive fit by fixing means (22), which can be inserted from the top into the plastic profiled section (11). The plastic profiled section (11) also has a base profile, which can be engaged into the steel profile (3) of the supporting structure. The plastic profiled section is embodied in the form of a profiled strip (11). The fixing means (22) is embodied as a wedge strip (11) and the engaging profiles (12, 13; 14, 15) are continuous in form. The plastic profiled section (11) has a continuous upward open trough-shaped recess (18) for securing the wedge strip (11). Lateral walls of the recess (18), which follow up with the engaging profiles (12, 13; 14, 15), are at least in the direction toward each other elastic, wherein the plastic profiled section (11) is flush relative to the upper side of the screening elements (5) and the wedge strip (22) has a head profile (24) which fills up a free space above the plastic profiled section (11) and between the front sides (16, 15) of the screening elements, and substantially in flush manner closes upper side of the adjacent screening elements (5).
