Abstract
A concrete-protecting panel with integrated undercut protuberances which has an enhanced resistance to groundwater pressure. The protuberances or wing-element pairs (3) of the plastic panel (1) have spread wing elements (3) which may spread open even further in their top region 3.1. The wing elements 3 are connected to one another by a supporting web 4, of which the height is at least 70% of one wing-element pair. The wing-element pairs 2 are fastened on the base plate 5 of the protuberance-containing panel 1 via a foot widened in an arcuate manner.
Claims16
A plastic panel (1), usable to line concrete components, comprising:
- a base plate having a first side and a second side opposite said first side;
- and
- at least one pair of spreading wing elements (3) integrally formed on and extending from at least one of said first and second sides of the base plate,
- wherein each of said wing elements has a first end integrally attached to said base plate and a free second end opposite said first end, each of said wing elements extending obliquely relative to said base plate,
- wherein each of said pair of wing elements defines a V-shaped profile with a foot region formed at a vertex of said V-shaped profile,
- wherein a supporting web (4) is provided in said foot region,
- wherein a height of the supporting web (4) is at least 70%, relative to a height of the wing elements (3), and
- wherein the wing elements (3) have arcuate transitions (6) to the base plate (5) in the foot region.
