摘要:
A ground anchor assembly (10) for a highway guardrail includes first and second spaced ground anchors (12, 14) and a connecting element (16) interconnected between the anchors (12, 14). An anchor cable (18) included in the guardrail assembly (10) is connected to the ground anchor assembly (10) adjacent the first ground anchor (12), and the second ground anchor (14) is situated farther from the central portion of the guardrail assembly (10) than the first ground anchor (12). In this way improved pull out resistance is provided.
摘要:
L'invention est relative à une barrière de sécurité pour voie de circulation, destinée notamment à arrêter un motard après une chute, apte à être montée sur des poteaux (11) régulièrement espacés le long d'une première voie de circulation. Elle est constituée par une pluralité d'éléments longitudinaux (1) disposés de façon contiguë dans l'alignement les uns des autres, chaque élément longitudinal (1) étant agencé de manière à pouvoir être mis en place sur deux poteaux adjacents (11) par déplacement suivant une direction perpendiculaire aux poteaux.
摘要:
The invention is essentially focused upon the development of elements made of a flexible material which will cover the cutting edges of the rails (2) and of the posts or vertical sections (1) which support the rails of the metallic guard-rails found in roads. They consist of a protective element for the cutting edges of the rails (2), an upper protective cap (8) which fits at the head over the upper side of the section (1) which protrudes from the rail, and lower lateral protective elements which embrace the front or rear sides of the section where it protrudes from the rail, or which independently attach to each of its flanges.
摘要:
A semirigid road barrier (1) wherein a rail (5) is connected to a number of posts (3) by respective connecting assemblies (6), each presenting a spacer (13) and a connecting device (14) for connecting the spacer (13) to the respective post (3); the connecting device (14) presenting a first (25) and second (26) cam guide assembly presenting respective cams (27) (28) on the relative spacer (13), and respective stop members (29) (30) associated with the relative post (3); the cams (27) (28) being defined by respective guide slots (31) (35), and presenting respective first portions (32) (36) cooperating with the respective stop members (29) (30) and with each other to define a substantially rigid connection of the spacer (13) and the respective post (3) at the initial impact stage wherein the post (3) is still substantially upright.
摘要:
A buffer or spacer (1) comprising a closed steel strip (7) substantially shaped like a regular or irregular parallelogram, which is welded to two supports (8, 9) in the form of strips (8, 9). The spacer (1) has the shape of a parallelepiped and is rigidly connected to the wavy blade (6) and to the post (4) by means of bolts or other fixing means. The support (8) of the blade (6) and the support (9) for the connection to the post (4), are made of a kind of steel having a different resistance with respect to the steel by which the closed strip (7) is formed. The supports (8, 9) may be provided with recesses or folding lines (12, 13) for a controlled deformation thereof and of the spacer (1), during the collision.
摘要:
A boundary marking system comprising cylindrical receptacles (14) having relatively large plates (10) flush with one end and adapted to be installed in the ground with the plate (10) at ground level. A marker stake (12) which is color coded to the top of the plate (10) is placed in the receptacle (14) through a hole in the plate (10) so that the stake (12) extends a foot or so above ground to mark a boundary. Because of the color coding, installation and replacement of the stakes (12) is facilitated. Moreover the particular character of the marked boundary may be perceived not only by the color of the stake (12), but also by the color of the flush plate (10) even if the stake (12) is missing. A hole maker (22, 24, 26, 28) to facilitate installation of the receptacle (14) is also disclosed.
摘要:
Road barrier (1) comprising: a series of support posts (2) which are adapted to be firmly fixed to the ground (P) in a substantially vertical position, arranged spaced next to each other along the lateral edge of the roadway; a series of horizontal crossbars (3), which are firmly fixed to the support posts (2) in a substantially horizontal position one after the other, so as to form a first longitudinal containment rail (4) extending along the lateral edge of the roadway at a predetermined height from the ground (P); and a series of additional oblong sections (10), which are made of an elastomer-based composite material and are firmly fixed to the support posts (2) in a substantially horizontal position one after the other, so as to form a second longitudinal containment rail (11) extending along the lateral edge of the roadway, below said first longitudinal containment rail (4).
