Double fonction pedestrian protection - DOLRE N246 (TL2 according to MASH*)

* determined by numerical computation
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/post

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 EN 1317-1/2/5, the performance are:
-
Minimum containment level: N2 (=TL2)
-
Maximum working width : Wn 4
-
Vehicle intrusion = VIn 3
-
Acceleration Severity Index (ASI) = 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 4.0 are M=14 kNm, V=43 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).
