摘要:
Dispositif de protection pour un mur et la zone marginale de ce mur ainsi que pour une zone réservée, comprenant une disposition régulière d'éléments de protection (1), les éléments de protection (1) étant reliés les uns aux autres au moyen d'éléments d'accouplement (2), remarquable en ce que lesdits éléments de protection (1) sont constitués par des tuyaux butoirs, qui peuvent être glissés dans les éléments d'accouplement et les traverser (2) de manière ajustée.
摘要:
Cet ensemble d'éléments comprend des éléments assemblables (2, 3) en un matériau relativement pesant et à fort coefficient de friction, de deux types, à savoir :
des éléments allongés (2) de formes identiques, comprenant des moyens d'assemblage (5, 6) à leurs deux extrémités longitudinales, ces moyens d'assemblage (5, 6) permettant d'assembler une série de ces éléments (2) en alignement les uns des autres, et des pièces d'angle (3), comprenant, sur deux faces non parallèles, des moyens d'assemblage (7, 8) complémentaires de ceux des éléments allongés (2).

Platte (1) zur Begrenzung einer Fahrspur (12,13) einer Straße bzw. zur Trennung zweier unmittelbar nebeneinander liegender Fahrspuren (12,13), wobei zumindest eine Längsseite (2,3) dieser Platte (1) mit einer, vorzugsweise in Gestalt einer ebenen Fläche ausgeführten, Abschrägung (8) ausgebildet ist.
摘要:
The invention relates to a guide system (20) placed along roadsides (13, 14), preferably in tunnels, that has guide elements and support bodies (30) which are anchored in the ground and which hold said guide elements. These guide elements are formed by roller elements (21, 22) which are coaxially arranged in a row, which are rotatably mounted at the support bodies (30) and which are arranged above the road surface (11) at a distance which is approximately equal to half the wheel diameter of vehicles (18). This significantly increases the amount of protection provided to vehicles as they near the sides of the road. These guide elements which are comprised of roller elements make possible a softer impact of a vehicle since usually the vehicle wheels come in contact first with the guide elements. The guide elements also provide a type of guidance of the forward-moving vehicle (18) during contact by virtue of the resulting rotation of the roller elements.

摘要:
Method and device for establishing a guard rail structure, in which a number of posts (4), each being provided with a threaded anchor (9), are brought into the ground simultaneously with the help of a robot (7) arranged on a vehicle (1). Subsequently, the vehicle (1) is moved and a guard rail segment (13) is connected to said posts (4) with the help of a second robot (11) arranged on a vehicle (12). Therein, snap fittings (16 - 19) are employed between the guard rail segment and the posts. The ends (23) of said guard rail segments (13) are designed in such a way, that they can be mated on mounting. The guard rail segments (13) are provided with signalling members (25, 26) and with cables (27) extending to said members. Members (26) can show a "green wave".
摘要:
Said signalling element being capable of taking up a first position wherein said signalling element is retracted at ground level and a second position wherein it is almost vertical; the actuating means enabling the signalling element (2) to shift, when operated, from one to the other of the first and second positions by rotation of the signalling element about the axis of rotation (7), and the signalling element further comprising at its base and above the axis of rotation, an elastic articulation (4) enabling it to be deflected in the direction opposite its retraction in the first position when it is subjected to a load resulting from the passage of a vehicle and to return to the second position when there is no more load.
