The invention relates to a plastic plate for lining concrete components
through which a fluid medium flows. Said plastic plate is provided with a
plurality of anchor elements (10) which are mounted on the side (1B) thereof
oriented towards the concrete component wall and which make it possible to
positively fixe said plastic plate to the concrete component. The side (1A) of
the plastic plate oriented to a medium is provided with a plurality of
adjacent flow elements (4) which are embodied in the form of elevated
structures comprising an upstream flank (4A) oriented in a flow direction (9)
and an oppositely oriented downstream flank (4B), wherein the superficial
areas located between the flow elements are smoothly shaped. In such a manner,
it makes it possible to increase a dragging effect of medium-carried particles
in order to avoid solid deposits even at a low flowrate. In the preferred
embodiment, the flow elements are constructed in the form of narrow webs which
have a wedge-shaped cross section and are distributed in individual rows (IV)
side by side transversally to the longitudinal axis (5) of the plastic plate.
La présente invention concerne une plaque de plastique conçue pour recouvrir des composants en béton qui sont traversés par un milieu fluide. Cette plaque de plastique présente sur la face (1B) tournée vers la paroi du composant en béton une pluralité d'éléments d'ancrage (10) qui permettent de relier la plaque de plastique au composant en béton par liaison de forme. Sur la face (1A) tournée vers le milieu, la plaque de plastique présente une pluralité d'éléments d'écoulement adjacents (4) qui sont conçus sous forme de structures en saillie présentant un flanc en amont (4A) orienté dans le sens d'écoulement (9) et un flanc en aval (4B) orienté dans le sens inverse du sens d'écoulement. Les zones superficielles situées entre les éléments d'écoulement sont lisses. Il est ainsi possible d'augmenter l'action de dragage des particules entraînées dans le milieu, de manière à empêcher les dépôts de matières solides même avec une faible vitesse d'écoulement. Dans un mode de réalisation préféré, les éléments d'écoulement sont conçus sous forme de nervures étroites présentant une section transversale cunéiforme, qui sont réparties en lignes individuelles (IV) les unes à côtés des autres, transversalement à l'axe longitudinal (5) de la plaque de plastique.
