DOLRE N2 DFPP(Doble Fonction Pedestrian Protection)
Outstanding design
Fuse system:
-
Saving installation time
-
Preservation of the support(concrete)
The lowest transmitted efforts of the market:
​
​
M=3,1 kNm*
V=12,5 kN/poteau*
Briefly ...
​
Steel restraint systems are linear elements designed to straighten the path of vehicles. They are made by assembling steel components.
​
In accordance with NBN EN1317-1/2/5, the performance are:
​
-
Minimum containment level: N2(=TL2*)
​
-
Maximum working width : Wn 4
​
-
Vehicle intrusion : VIn 3
​
-
Acceleration Severity Index : ASI A!
​
​
The additional features are:
​
-
To ensure the guardrail function, the overall height in relation to the concrete support ≥1,20 m
​
-
To limit the influence on the structure, the maximum space requirement between front and rear post face = 28 cm
​
-
To limit or even avoid reinforcements, the forces transmitted by post are M=3,1 kNm, V=12,5 kN
​
-
For maintenance reasons and possible in situ push tests the fussible system it is located outside of the anchorage, meaning , on the post.
​
Guardrail fonction:
-
Handrail height at 1.2m.
​
-
Filling preventing the passage of a 15cm diameter cylinder.
​
-
CE certification of the entire system (slide + filling).
