摘要:
Noise-insulating acoustic barrier formed by panels (10) comprising a mass of sound-absorbing material (17) arranged between two C-shaped profile sections (16) that are inserted between the flanges of I-shaped risers (11). Pairs of fretted plates (14) enclose said panels on their front and rear sides and have their edges joined to each other by means of an alternate overlapping pattern. The barrier is easy to manufacture directly on the site of installation.
摘要:
Sheet-steel road safety barrier with a profile of a New Jersey type, adapted to be installed on road embankments. The barrier is formed by modular elements, each one of which is constituted by a cover wall (10) made of folded sheet-steel and provided with a rear longitudinal reinforcing rib (11). The elements are fixed to vertical beams (12) that are stuck deep in the ground and are linked with each other by means of longitudinal tension rods (14). The beams are provided with plates (15, 16) in their portion sticking in the ground. The barrier is effectively anchored to the ground and provides a high extent of integration of its component parts.

摘要:
Metallic safety barrier employed to delimit the side of the road or as a central traffic divider, the barrier consisting of a plurality of metallic modular elements, which can be associated reciprocally to each other and to the ground (12), the modular elements including a hollow bearing structure (13) associated with transverse stiffening ribs (21) and including at the lower part pockets (15) to house the means (16) which anchor the barrier to the ground (12), the pockets (15) including, in the proximity of the supporting surface, a hollow chamber (23) cooperating with at least the upper part of the anchor means (16), the hollow chamber (23) being at least three times wider than the size of the anchor means (16).
