摘要:
Impact absorbing street pole extending substantially along a longitudinal direction, the street pole comprising an elongated extension (17) detachably connected at a predetermined height to a first part (18) of the street pole such that upon impact on the first part of the street pole, the elongated extension disconnects from the street pole.

A breakaway support post (130) is provided for a highway guardrail system (120) to enhance the safety of a vehicle impacting with either the rail face of the associated guardrail or one end of the guardrail facing oncoming traffic. For some applications, the breakaway support post (130) may be formed from a steel I-beam with one or more elongated slots formed intermediate the ends of the steel I-beam. The slots are preferably formed in the flanges of the I-beam which are in turn aligned generally parallel with the associated guardrail. For other applications, a breakaway support post may have an upper (142) and a lower (144) portion with a rotatable coupling (140) assembly disposed therebetween. A shear pin (156) or other releasing mechanism is preferably provided to maintain the upper and lower portions generally aligned with each other prior to the impact of a vehicle with one end of the associated guardrail.
摘要:
An impact absorbing pole 5 is disclosed. The pole is formed as a one-piece unit that includes an outer wall 7 and a hollow interior 9 and has a base section 11 for locating the pole below the ground and a pole section 13 for extending upwardly above the ground. The pole is formed so that, in use, the pole can deform above and below ground level when the pole is installed in the ground and is contacted by a vehicle.

A connecting structure (4) for a traffic pole, such as a lamp post (1), composed of two pole parts (2, 3), comprises connecting pieces (7, 8) which can each be connected to a pole part in such a manner that the connecting pieces and pole parts are in line with one another, which connecting pieces (7, 8) are provided with end faces (11) which face one another and a connecting part (9) which can be connected to a pole part (2,3), a mounting face (19) having recesses (17) opening into a periphery thereof, which mounting face (19) is turned away from the associated end face (11), as well as clamping members (13) which are accommodated in recesses (17) which are aligned with respect to one another and which are supported on mounting faces (19) which are turned away from one another in such a manner that the end faces (11) of the connecting pieces (7, 8) are pushed together. The recesses (17) open into the inner periphery of the mounting faces (19).

A breakaway support post (18, 210) is provided for a highway guardrail system (10) to enhance the safety of a vehicle impacting with either the rail face of the associated guardrail (16) or one end of the guardrail facing oncoming traffic. The breakaway support post may have upper and lower portions (26, 28) with a releasable coupling assembly (29, 211) disposed therebetween to maintain the upper and lower portions generally aligned with each other prior to the impact of a vehicle with one end of the associated guardrail. The breakaway support post may also have releasable coupling assembly (301) disposed between the upper and lower portions and a cable (303). The releasable coupling assembly may allow the upper portion to separate from the lower portion.
摘要:
The disclosure relates to a post for supporting one or more catchment devices (3) such as wires or sheet metal profiles in a road barrier (1). The post (4) supports a catchment unit (2) with catchment devices (3), the post (4) and the catchment unit (2) being interconnected by a bolt (12) which is released in the event of a collision whereafter the catchment devices (3) are held together by fittings (7) but released from the post (4). The lower region of the post (4) is anchored in the ground in a ground anchorage (13). The post (4) has a flattened section (14) in its lower end which is disposed transversely of the direction of travel of the carriageway. The flattened section (14) entails that the post (4) is quite easy to bend in the collision direction, and a weakening entails that the post (4) is bent at the ground in the event of a collision.
