Mounting guard rails (barriers) S1 for the upper guard rail belt
The guardrails S1 are to be overlapped in the jointed area in accordance with the
direction of traffic, so that vehicles cannot get caught up on them. The drilled 9 mm
diameter hole indicates that the guard rail in the joint region (upper part) is facing the
respective carriageway. In order to be able to overlap the guardrail in the jointed
area, the carriageway side of the guardrail ends (lower part) are goosenecked.
The guardrails are bolted together with the extension profiles on the guardrail axis at
each IPE160 post (every ~1.900 mm). In order to do so, a coach bolt M16x50 FK 4.6
is fed through the axially aligned bore holes in the guardrail S1 and the elongated
hole 20x40 in front of the extension profile bar on the IPE160 post, as viewed in the
direction of traffic. It is then secured in place with a hexagon nut M16 FK 5 (see Fig.
2).
The guardrail joint is additionally secured with six coach bolts M16x35 FK 4.6. It is to
be ensured when tightening the hexagon nuts M16 FK 5 that the square-shaped anti-
twist protection for the bolt head is correctly positioned to the guardrail.
A washer 40x18x4 is to be aligned under each hexagon nut M16 FK 5. The exception
to this is the four off-centre bolts in the crash barrier joint, where two reinforcement
flanks are to be installed instead of the washers 40x18x4 (see fig. 2).

Install sliding profile S1
The sliding profiles are to be aligned on the side of the V140 post pointing towards
the traffic, so that the two sides lay flush with the V140 posts.
The sliding profiles are attached to each V140 post. In order to do so, a coach bolt
M10x25 FK 4.6 is fed through
the inner side of the sliding
profile through the elongated
hole 160x12 in the upper flank
of the sliding profile and
through the elongated hole
30x12 mm of the V140 post
and fixed in place with a
washer 11 and hexagon nut
M10 FK 5.
The sliding profiles are to be overlapped in the jointed area in accordance with the
direction of traffic, so that vehicles cannot get caught up on them (see Fig. 3).
