摘要:
The present invention is directed to a vehicle safety catch fence system, the system comprising: two or more posts; two or more longitudinal cables operatively coupled between the two or more posts; a transverse cable, wherein the transverse cable is operatively coupled to the two or more longitudinal cables; and two or more cable clamps, wherein the two or more cable clamps operatively couple the transverse cable to the two or more longitudinal cables.

A guardrail system includes a plurality of posts spaced apart along a longitudinal direction and a plurality of rail sections extending between and coupled to the spaced apart posts. Each of the rail sections includes an uppermost surface. A cable extends along the longitudinal direction and is coupled to the rail sections and/or posts. The cable is vertically spaced above the uppermost surface of the rail sections. A guardrail retrofit kit includes a front anchor bracket, a rear anchor bracket, an intermediate bracket and a cable having end portions adapted to be coupled to the front and rear anchor brackets. The intermediate bracket is configured to releasably capture the cable. Methods of retrofitting a guardrail system and arresting a vehicle impacting a guardrail system are also provided.

Disclosed is an impact absorbing barrier assembly. The assembly includes a support having a pipe configuration and installed at the center line or the side of a road, an impact absorbing cylinder combined to the support and including a cylinder having a penetrating through-hole and being made by using one of ethylene vinyl acetate (EVA) and soft polyurethane, and including a rotation support pipe corresponding to the outside circumference of the support and inserted into the through-hole, a fence guide horizontally installed at upper and lower portions of the impact absorbing cylinder and at front and rear portions of the support to connect the supports, a fence guide combining device, and a rotation support device to support the rotation of the impact absorbing cylinder. The impact from a car collision with the impact absorbing barrier assembly may be reduced.

A breakaway support post for a guardrail includes an upper post member and a lower post member. The upper and lower post members are overlapping and configured such that the upper and lower post members are non-rotatable relative to each other about an axis extending in an axial impact direction. In one embodiment, a tensile fastener extends in the axial impact direction and connects overlapping portions of the upper and lower post members. In another embodiment, a shear fastener extends transversely to the axial impact direction and is the only connection between the upper and lower post members. In another aspect, a guardrail assembly includes first and second rail sections, with a deforming member deforming the first rail section as it moves relative to the second rail section. Methods of using and assembling a guardrail assembly are also provided.

A combined guardrail and cable safety system is disclosed. In one aspect, a safety barrier incorporating the teachings of the present disclosure may include a plurality of cable posts spaced from each other and disposed adjacent to a roadway. At least two cables may be releasably engaged with and supported by the cable posts. The cable posts and the at least two cables may cooperate with each other to prevent a vehicle from leaving the roadway. A plurality of guardrail posts may also spaced from each other and disposed adjacent to the roadway longitudinally spaced from the plurality of cable post. A box beam guardrail beam may be attached to the plurality of guardrail posts. The at least two cables may operably extend from the cable posts to engage respective cable anchor brackets attached to the box beam guardrail beam.

A barrier system includes at least first and second reinforced concrete posts, each concrete post including at least one conduit formed therethrough having first and second ends and a strain relief sector formed therein at the first end of the conduit. At least one tension cable extends between the posts. The tension cable extends through the conduit of each post and has a cable end secured to the post at the second end of each post's conduit.

This invention relates to guardrails and guardrail impact heads for use in roading networks or vehicle road lanes requiring separation by a barrier. The invention provides an impact head for a guardrail including cable routing means adapted to form a convoluted path through which a cable can be threaded. The convoluted path that the cables must follow through the impact head of the invention restricts movement of the cable through the head, thereby providing sufficient friction to slow down the movement of the impact head during a vehicle impact. The invention also provides a method of constructing a guardrail including the steps of slidably interconnecting a plurality of rails and attaching them to posts, positioning an impact head according to any one of the preceding claims at one end of the slidably interconnected rails, threading at least one cable through the impact head and anchoring the cable to the ground.

A divider barrier 1 for roadway delineation includes detachably juxtaposed divider members 2, 3, 4. The divider members have each a housing-like base body 5 which can be placed on the ground and has slanted roof-shaped lateral collision plates 6, 7. Connected to the lower longitudinal edges 10 of the collision plates 6, 7 are support plates 11, 12 which extend from the base body 5 outwards. A guide bar 15 is provided above the base body 5 at a vertical distance thereto. Connecting means 18–21 are provided to detachably couple successive divider members 2, 3, 4 with one another. The support plates 11, 12 of two successive divider members 2, 3, 4 are detachably connected to one another by means of fishplates 35 on the underside, wherein each fishplate 35 is hereby fixed with its first end portion 36 under the support plate 11 of the one divider member 2, 3, 4 and with its second end portion 37 under the support plate 12 of the following second divider member 2, 3, 4. Each of the first end portion 11 as well as the second end portion 12 of each fishplate 35 has a receiving opening 40 for engagement of a pin 41 constructed of round configuration and secured under each of the support plates 11, 12. As a consequence of these pins 41, the divider barrier 1 is stiffened against lateral displacement.

A combined guardrail and cable safety system is disclosed. In one aspect, the present invention teaches a safety barrier including a plurality of cable posts spaced from each other and disposed adjacent to a roadway. At least two cables are releasably engaged with and supported by the cable posts. The cable posts and the two cables cooperate with each other to prevent a vehicle from leaving the roadway. A plurality of guardrail posts are spaced from each other and disposed adjacent to the roadway longitudinally spaced from the plurality of cable post. A guardrail beam is fixedly coupled to the plurality of guardrail posts and including slots. The two cables extend from the cable posts through respective slots formed in the guardrail beam permitting each cable to engage a respective cable anchor bracket securely fastened to a portion of the guardrail beam.
