The present invention relates to an emergency alert and warning apparatus and, more particularly, to a road emergency alert and warning apparatus which is installed on a median strip or a guide rail of an expressway or the like to alert a driver of a rear vehicle of an emergency situation when a traffic accident occurs during nighttime driving, thereby preventing an additional secondary accident. According to an embodiment of the present invention, the emergency alert and warning apparatus comprises: an operation switch which is installed on a median strip or a guide rail of a road to allow a user to generate an operation signal when a traffic accident occurs; a control unit which receives the operation signal to output a control signal, and transmits or relays traffic accident notification data to another neighboring emergency alert and warning apparatus through a wired or wireless communication; a warning display unit which is installed rearward with respect to a traveling direction of a vehicle and includes a plurality of LEDs that are turned on and off in response to the control signal of the control unit; and a photovoltaic cell which converts solar energy into electric energy, processes the electric energy into a constant voltage through a DC/DC converter, and supplies power.

A traffic barrier structure includes posts fixedly installed at the median or roadside of the road, guiderail units composed of guiderails horizontally connected in series between the posts and each having a longitudinal slot, a rail holder installed in the guiderail and having a slot holder piece closely engaged against the slot in the guiderail and a deformation-resistant piece extending from the slot holder piece, closely conforming to a portion of an inner curved portion of the guiderail, to prevent deformation of the guiderails and enlargement of the slots when shock is applied the guiderails, and a rail connector inserted into respective connection part of adjacent guiderails to longitudinally connect the adjacent guiderails.

A roadway guardrail system including a rail and plurality of support posts assembled such that upon impact from a vehicle the rail moves upwardly with respect to the support posts. Fasteners and block-outs may be used in the operative coupling of the rail to the support posts. Upon impact the fasteners and the block-outs move upwardly with respect to the support posts and the rail moves upwardly along with the fasteners and the block-outs.

The present invention provides a spacer for a road safety barrier. The spacer includes a post and a rail connected to the post via an intermediary of the spacer and a connector. The spacer includes a rail support having a front face to be fastened to a rail, a rear face to be fastened to a post and a flange that connects the front face to the rear face. The front face includes a connector housing and a weaker area connecting the connector housing to the upper edge of the front face, the mechanical resistance of the weaker area being strictly lower than the intrinsic mechanical resistance of the constituent material of the remaining part of the front face of the rail support. The spacer also includes a rail guide including a fastening area for fastening the rail guide to a post above the rail support, a connecting piece and a rail reinforcement area for fastening the rail guide to the reverse side of the rail.

A roadway guardrail system including a rail and plurality of support posts assembled such that upon impact from a vehicle the rail moves upwardly with respect to the post. Fasteners may be used in the operative coupling of the rail to the support posts, such that upon impact the fasteners move upwardly with respect to the support posts and the rail moves upwardly along with the fasteners. The guardrail system may further include a reinforcing member that is slidable along the post and operatively coupled to the rail with the fasteners, such that the rail and fasteners slide along with the reinforcing member with respect to the support posts. The reinforcing member may be a spacer of various shapes, a washer, an additional rail section, or other type of member that allows the rail to slide upwardly with respect to the post.

The present invention relates to posts, carriages, methods of manufacturing the components and their assembly into a barrier. The invention also includes a Z post attachment includes an attachment tab 8.016 and end engagement flange 8.024, 8.026 adapted to engage the end of the post. The arrangement can include a delineator 8.030 which is skew in relation to the tab 8.016, so as to provide reflector faces 8.032 which face oncoming traffic.

A roadway, guard rail or safety barrier having a post and beam construction wherein the beam is mounted to the post by means of a carriage, the beam being secured to the carriage by a securement means, the carriage being adapted to travel longitudinally relative to the post in the event of a collision, the post further including at least one carriage support means, and one or more engagement means on an outer face of the post, the engagement means being adapted to be engaged by the securement means to provide resistance to movement of the carriage with respect to the post, wherein the carriage is sized and shaped so as to not engage or to minimize engagement with the engagement means during the movement.

A crash barrier system includes upper posts, box beams, upper tube profiles and barrier rails. The box beams are connected to the upper posts on a front side of the crash barrier system. The upper tube profiles are connected to the box beams. The barrier rails are fastened to the upper tube profiles. The upper posts are arranged axially parallel to one another at a uniform axial post spacing along the box beams. The upper tube profiles are arranged axially parallel to one another at a uniform axial tube spacing along the box beams. The post spacing differs from the tube spacing.

An end plate configured to integrate with a first end wall or a second end wall of a roadway barrier comprises a body wall and a brace. The body wall includes a front surface and a rear surface, and is configured to couple with a first side wall and a second side wall of the roadway barrier. The brace is attached along a width of the rear surface of the body wall and extends rearward therefrom. The brace includes a first notch and a second notch, with each notch providing an opening in the brace that allows the brace to bend at the notch locations.

A strapping apparatus for coupling an article to a post, the apparatus including a post adapter including a first side configured to engage with the post and a second side comprising a recess; a retaining element at least partially located in the recess of the post adapter; and a strap configured to extend around the post, the strap including: a first end configured to be removably coupled to post adapter; and a second end configured to be received in the retaining element.
