Ces écrans sont essentiellement constitués de panneaux acoustiques (3) de 1,50 m de haut par 2,00 m de large environ, de préférence transparents pour conserver la vue. Les panneaux sont maintenus par des poteaux (2), distants de 2,00 m environ, solidaires d'un soubassement (1) de 0,50 m à 1,50 m de haut environ au-dessus du sol qui assure la stabilité au vent. Le soubassement peut être constitué de bacs auto-stables lestés le plus souvent par de la terre, ou d'un muret solidaire d'une fondation classique enterrée en béton.

A safety barrier for roads, used as traffic divider, comprises a double row of concrete made New Jersey barrier elements (1, 1') which allow the realization of a hedge on the interposed earth against light rays. The earth is contained in a sack (2) made of nonwoven fabric, fixed to both elements (1; 1') of the barrier, so as to leave gaps (8, 8') behind the rear walls of the barrier elements (1; 1'). The gaps (8, 8') and a plurality of sliders or runners (A) provided on the barrier's base, allow during impact a controlled displacement of said barrier (1, 1'). The calibration of decelerations is adjusted by the material used for the sliders (A).

The present invention concerns a panel with a horizontal or vertical transverse ridged cross-section, that can be interconnected in sucession with other panels of the same type to form a continuous screen which is installed above the central barrier separating the two carriageways of a road, or above the barriers that delimit the sides of a road; this screen, particularly when installed above the central barrier of a road, being designed to be capable of simultaneously acting to screen off full beam headlamps and spray from wet road surfaces from the opposing carriageways of a road, and to act as a reference at night and/or in conditions of poor visibility, due to the high refractive power of its surfaces.

The invention relates to a soundproofing element (2) which comprises a first sheet (4) consisting of a flexible material and a second sheet (6) consisting of flexible material. The sheets (4, 6) are positioned at a distance from one another and at least two chambers (14, 16) are formed between said sheets (4, 6) for receiving a filler medium. According to the invention, the first sheet (4) and the second sheet (6) are connected by connection means located on opposing surfaces. Appropriately, the connection means have at least one connecting length (8) consisting of flexible material. The inventive soundproofing element (2) is constructed simply and robustly. When empty, it is easy to handle and transport. In addition, the inventive soundproofing element is suitable for filling with a high-density filler medium, for example sand or similar.
摘要:
Eine Lärmschutzwand (1) mit relativ schmaler Basis, aber ausreichender Höhe und vorteilhafter Stabilität besteht aus einzelnen rechteckigen Drahtgitterkörben, die wiederum aus gelenkig miteinander verbundenen Längs- und Querwänden zusammengesetzt sind. Die Querwände sind dabei mit den Horizontalstäben zugeordneten Haken versehen und weisen über den unteren Horizontalstab vorstehende Vertikalstäbe auf, so daß sie aufeinander bzw. ineinander gesteckt bzw. auf entsprechende Stützelemente gesteckt werden können. Die Längswände (3,4), die nach dem Einhängen in die Querwände einen nach außen gerichteten Bauch oder Bogen bilden werden dann durch Umbiegen der Haken mit den Querwänden, die hier selbst ja schon aufgerichtet und stabilisierst sind verbunden. Zum Stabilisieren dient dabei ein jeweils zwei Querwände verbindendes Versteifungselement, meist in Form eines L-Profils, das mit dem Winkel nach oben angeordnet ist, so daß sich Erdreich nicht festsetzen kann. Diese einzelne stabile Drahtgitterkorb wird mit entsprechenden weiteren Drahtgitterkörben verbunden, in dem jeweils die Querwände aufeinandergestellt bzw. gesteckt werden, so daß sich ein sehr stabiles Gesamtbauwerk ergibt, in daß im nach hinein das Erdreich eingefüllt werden kann. Eine Verdichtung ist dabei in der Regel nicht notwendig, so daß ein derartiger Erdwall bzw. da eine entsprechende Lärmschutzwand mit relativ wenig Aufwand errichtet werden kann.
摘要:
A barrier forming a two-row traffic divider or a lateral barrier for an artificial trench, comprising a continuous deformable structure (3, 3'; 13, 13'; 23, 23') including a plurality of modules which are mutually connected and are simply laid on the curbstone or pavement. The deformable structure allows the calibrated deceleration of the light vehicles. In case of a barrier formed by a two-row traffic divider, a central container (1) stops the movement of a heavy vehicle, while the same effect is obtained by means of the toe wall (16) in case of a lateral barrier.
摘要:
L'invention concerne un dispositif de protection routière destiné à être disposé sur au moins l'une des bordures d'une voie de circulation, comprenant une partie inférieure (1) formant un socle, une partie supérieure (2) constituant un écran de protection et une partie latérale (3) formant une barrière de sécurité, la partie supérieure (2) et la partie latérale (3) ménagent entre eux un volume libre (5), La partie inférieure (1) comprend au moins un évidement (4) ouvert vers le haut et destiné à coopérer avec la partie supérieure (2) à la fixation de cette celle-ci sur la partie inférieure (1), l'évidement (4) étant espacé de la partie latérale (3). L'invention concerne également un procédé de réalisation d'un tel dispositif.
