Dispositif d'ancrage (1) d'un élément à ancrer, comprenant: - un élément en plaque (10) destiné à être placé en position horizontale, dans le sol, dans le fond d'un trou, à l'utilisation, - un fourreau (12) formant un logement longitudinal destiné à la réception de l'élément à ancrer, le fourreau étant fixé sur l'élément en plaque (10), - des nervures (14) fixées à l'élément en plaque (10) et au fourreau (12) de manière à répartir au moins une partie des efforts transversaux reçus par le fourreau (12) sur l'élément en plaque (10), le dispositif comprenant en plus une pluralité de portions d'espace annulaire (16) autour du fourreau (12) s'étendant radialement au-delà l'élément en plaque (10), lesdites pluralités de portions d'espace annulaire (16) étant libres de tout élément constitutif du dispositif d'ancrage (1).
摘要:
The present invention relates to bituminous coated materials including a granular fraction and a binder, characterised in that in the granular fraction all or part of the elements are selected from among lightweight, non-absorbent aggregates with a density of less than 1.6 t/m 3 and a water absorption coefficient of less than 15 %. The invention also relates to the use of light, non-absorbent aggregates with a density of less than 1.6 t/m 3 and a water absorption coefficient of 3 % to 15 % for the production of light bituminous coated materials. The invention further relates to pavements obtained by applying at least one layer of the coated materials according to the invention and to a method for applying a surface course to a surface raised above the ground which includes a step of applying coated materials according to the invention.

The invention relates to a device (3) for printing a raised pattern on a plate member, characterized in that the device includes a non-planar printing surface (30) and in that a portion at least of said surface includes a raised pattern (31) complementary to a catadioptric raised pattern. The invention also relates to a method for making a plate member, including the following steps: providing a plate member (4) intended for receiving a catadioptric raised pattern (31) on the surface thereof, and printing a catadioptric raised pattern (31) on the surface of the member (4) using the printing device so as to scroll the printing surface of the device on the surface of the member (4).
