Claims
- 1. 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.
- 2. The plastic panel as claimed in claim 1, wherein a radius of the arcuate transition is approximately 50% of the thickness of a wing element.
- 3. The plastic panel as claimed in claim 1 wherein the wing elements (3) enclose a larger spreading angle at said free second ends, beginning from an end of the supporting web (4) which is directed away from the base plate, than in the region of the supporting elements (3).
- 4. The plastic panel as claimed in claim 1, wherein in each case two wing elements (3) are offset in relation to one another and are connected to one another via at least one supporting web (4).
- 5. The plastic panel as claimed in claim 4, wherein the wing elements (3) of a wing-element pair (2) are offset in relation to one another virtually over an entire width and are connected to one another in mutually adjacent regions via the supporting web (4).
- 6. The plastic panel as claimed in claim 1, wherein the wing elements (3) of a wing-element pair (2) are aligned with one another and the respective supporting web (4) is provided symmetrically between the wing elements.
- 7. The plastic panel as claimed in claim 1, wherein the wing-element pairs (2) each have two end supporting webs.
- 8. The plastic panel as claimed in claim 1, wherein in each case one end supporting web is provided on both sides of the wing-element pairs (2) with wing elements (3) of the same width.
- 9. The plastic panel as claimed in claim 8, wherein additional supporting webs (4) are provided between the end supporting webs.
- 10. The plastic panel as claimed in claim 7, wherein the wing elements (3) are of different widths (7) and the supporting webs (4) extend from the longitudinal sides of the smaller-width wing element (3) perpendicularly to the larger-width wing element (3).
- 11. The plastic panel as claimed in claim 1, wherein the mutually offset wing elements (3) of a wing-element pair (2) are connected to one another via in each case one supporting web (4) which is of essentially the same width as the wing elements (3).
- 12. The plastic panel as claimed in claim 1, wherein a width (7) of the supporting web (4) between a pair of wing elements (3) is smaller than in a region connecting two pairs of wing elements (3).
- 13. The plastic panel as claimed in claim 1, wherein the wing elements are of rectangular, square or polygonal cross section.
- 14. The plastic panel as claimed in claim 13, wherein the wing elements have beveled or rounded edges.
- 15. The plastic panel as claimed in claim 1, wherein the wing elements are of round, oval or elliptical cross section.
- 16. The plastic panel as claimed in claim 2, wherein the wing-element pairs (2) each have two end supporting webs.
