Abstract
This invention relates to a road barrier, particularly to a road barrier for separating traffic lanes on a bridge. In the preferred embodiment, the barrier is made up of beams formed from steel three-beam guardrail sections. Steel tubes or flanges are welded to the top and bottom of the guardrail sections and a transverses stiffener is welded to one side. The barrier's sections are removable mounted by pins in anchors attached to the bridge deck.
Claims27
A movable road barrier for guiding flow of traffic on a road surface comprising:
- a beam extending lengthwise in a direction parallel to the flow of traffic for separating the flow of traffic;
- and
- means for removably attaching the beam to the road surface, said means comprising:
- a pin disposed in an anchor in the road;
- means for removing the pin from the anchor;
- and
- means for providing for a variable connection point between the pin and the anchor.
A movable road barrier for guiding flow of traffic on a road surface comprising:
- a beam extending lengthwise in a direction parallel to the flow of traffic;
- and
- means for removably attaching the beam to the road surface, said means comprises:
- a pin disposed in an anchor in the road immovably attached to the beam;
- means for removing the pin from the anchor comprising means for lifting the pin and beam as a unit from the road and out of the anchor;
- and
- means for providing for a variable connection point between the pin and the anchor.
A movable road barrier for guiding flow of traffic on a road surface comprising:
- a beam extending lengthwise in a direction parallel to the flow of traffic;
- and
- means for removably attaching the beam to the road surface, said means comprising:
- a pin disposed in an anchor in the road movable with respect to the beam;
- a handle for removing the pin from the anchor;
- and
- means for providing for a variable connection point between the pin and the anchor.
A movable road barrier for guiding flow of traffic on a road surface comprising:
- a beam extending lengthwise in a direction parallel to the flow of traffic, wherein the beam comprises two three beam guardrail sections;
- and
- means for removably attaching the beam to the road surface, said means comprising:
- a pin disposed in an anchor in the road;
- means for removing the pin from the anchor;
- and
- means for providing for a variable connection point between the pin and the anchor.

A movable road barrier for guiding flow of traffic on a road surface comprising:
- a first beam extending lengthwise in a direction parallel to the flow of traffic for separating the flow of traffic;
- means for removably locking the first beam to an adjacent beam;
- and
- means for removably attaching the first beam to the road surface, said means for attaching comprising a pin disposed in an anchor in the road and means for removing the pin from the anchor.
A movable road barrier for guiding flow of traffic on a road surface comprising:
- a first beam extending lengthwise in a direction parallel to the flow of traffic;
- means for removably locking the first beam to an adjacent beam, wherein the means for removably locking comprises a bar assembly attached to adjacent beams at two points on each beam;
- and
- means for removably attaching the first beam to the road surface, said means for attaching comprising a pin disposed in an anchor in the road and means for removing the pin from the anchor.
A movable road barrier for guiding flow of traffic on a road surface comprising:
- a beam extending lengthwise in a direction parallel to the flow of traffic for separating the flow of traffic;
- and
- means for removably attaching the beam to the road surface, said means comprising:
- an anchor comprising a plate attached to the road surface,
- a pin disposed in an opening fromed in the anchor, and
- means for removing the pin from the anchor.
A movable road barrier for guiding flow of traffic on a road surface comprising:
- a beam extending lengthwise in a direction parallel to the flow of traffic;
- and
- means for removably attaching the beam to the road surface, said means comprising:
- an anchor comprising a plate attached to the road surface and having an opening formed therein, wherein the anchor opening is formed as a slot whose length along the axis parallel to the beam is longer than its width,
- a pin disposed in the opening, and means for removing the pin from the anchor.
