Abstract
Abstract The shock-absorbing barrier (1) made of plastic material comprises a number of main bodies (2) consecutively interconnected in mutual alignment relationship and exhibiting each a substantially parallelepiped and horizontally elongated configuration. Each main body (2) consists of a base wall (4), a top wall (5), two side walls (6) each at either end of the main body, a front wall (7) exhibiting a plurality of absorption recesses (7a) extending in a substantially vertical direction over the whole height of the front wall and a rear wall (8) provided with a plurality of longitudinal parallel ribs (8a) and having a sectional profile matching the shape of a guard-rail (11) against which the barrier (1) is located in abutment. Each main body (1) is hollow at the inside to be filled with a liquid or other filling material.

A shock-absorbing barrier (1) for road uses made of plastic material and comprising a number of main bodies (2) consecutively interconnected in mutual alignment relationship and exhibiting each, in a horizontally elongated configuration: - a base wall (4); - a top wall (5) extending above the base wall (4); - two side walls (6) extending between the base (4) and top (5) walls at either end of the main body (2); - a front wall (7) extending between the base wall (4), top wall (5) and side walls (6); and - a rear wall (8) parallelly spaced apart from the front wall (7) and extending between the base wall (4), top wall (5) and side walls (6), characterized in that each of said main bodies (2) exhibits a substantially parallelepiped configuration and is provided with a number of absorption recesses (7a) extending substantially in a vertical direction over the whole height of the front wall (7) and a number of longitudinal ribs (8a) parallel to each other and extending over the rear wall (8).
Claim 2
Dependent Claim
30 words
A shock-absorbing barrier according to claim 1, characterized in that said absorption recesses (7a) have a depth the value of which ranges between 1/5 and 1/3 of the barrier thickness.
Claim 3
Dependent Claim
30 words
A shock-absorbing barrier according to claim 1, characterized in that said longitudinal ribs (8a) are insertable into grooves matching the shape of said ribs and offered by a guard-rail (11).
Claim 4
Dependent Claim
26 words
A shock-absorbing barrier according to claim 1, characterized in that it further comprises connection means to fixedly secure the main bodies (2) to the guard-rail (11).
Claim 5
Dependent Claim
68 words
A shock-absorbing barrier according to claim 4, characterized in that said connection means comprises, for each main body, an anchoring rope (22) extending across the main body (2) itself and having, at one end thereof, a locking head (23) acting on said front wall (7) and, at the other end thereof, a threaded end element (24) engageable across the guard-rail (11) by means of a fastening nut (25).
Claim 6
Dependent Claim
60 words
A shock-absorbing barrier according to claim 1, characterized in that each main body (2) is connected to the contiguous main body (2) through a connecting body (3) located intermediate two main bodies, said main body exhibiting, at each side wall (6) thereof, a joining jug (18) to be fitted into an engagement seat (19) offered by the connecting body (3).
Claim 7
Dependent Claim
26 words
A shock-absorbing barrier according to claim 6, characterized in that said connecting body (3) has connection means to fixedly secure said bodies to the guard-rail (11).
Claim 8
Dependent Claim
73 words
A shock-absorbing barrier according to claim 7, characterized in that said connection means comprises, for each connecting body, an anchoring rope (22a) extending across the connecting body (3) itself and having, at one end thereof, a locking head (23a) acting on the front wall (15) opposite that in contact with the guard-rail (11) and, at the other end thereof, a threaded end element engageable across the guard-rail by means of a fastening nut.
