Definitions

  • the invention relates to a safety barrier that prevents vehicles from falling off a bridge or running off the road.
  • guardrail barrier/traffic barrier/crash barrier/barricades on roadways or bridges for preventing vehicles from falling out of broadways line is common, e.g. in the case of a slippery road.
  • the basic factor used to determine whether a road or bridge safety barrier structure is working correctly/expectedly is a positive result of crash tests.
  • a typical solution for such barriers is a structure comprising of posts/stakes, one or more guides connected over a length with the posts directly or indirectly by means of additional known elements for combining guides.
  • Other used elements are: profile strips, pipes, wire ropes, brackets.
  • the posts can be driven into the ground of the shoulder or attached to the supporting structure of the bridge of flyover with the use of basket anchors, adhesive anchors or bolts fixing them directly to the steel structure of the bridge or flyover.
  • the guides are made of ⁇ -shaped sheet section in particular made of metal, sinusoidal sheet, moulding, specially bent or cold-formed sections, solid bars.
  • A-type or B-type or 3n-type guide in safety barriers.
  • Said barriers have a specific/particular stiffness, strength and its flexibility that lead to lack of occurrence of excessive overloads in people present in the vehicle during a collision. All its components included in barriers impact on their level of working in expected way.
  • Know types of guides are shown in Figs. 1, 2 and 3 .
  • Patent description US6010275 discloses a design of a road barrier consisting of impact-absorbing elements and a barrier in the form of a row of posts connected to a guide.
  • the absorbing elements are in the form of cylindrical elements made of a flexible material, for example rubber tires.
  • a road barrier for traffic routes with a large number of front-connected wall elements for absorbing kinetic energy from the impact of a car, each of which is connected to at least one anchoring element located on a surface, for example a road surface, bridge surface or another surface, with at least one fastening element is known from the Polish patent description PL192339 .
  • the at least one fastening element is sliding mounted relative to at least one anchoring element, and the wall element is, with its at least one fastening element, sliding mounted between a rest position and a position shifted by a set distance from the rest position.
  • At least one anchoring element of the barrier is a rail element anchored to the ground, positioned approximately perpendicularly to the longitudinal dimension of the wall element and assigned to the sliding fastening element.
  • An element of a road barrier intended for interoperation with other segments forming a linear barrier separating two opposite traffic lanes is also known from the Polish description of the utility model No. 54951.
  • the solution has the form of a polygonal solid, which in cross-section is a truncated, tapering upward, two-stage cone supported on a rectangular base, which in the front and rear planes has vertical recesses running parallel to the vertical axis, in which the connecting holders offset to each other are mounted.
  • a trapezoidal process opening extends longitudinally.
  • mounting holes are arranged in the upper part of the side walls.
  • a road safety barrier consisting of mounted posts and a guide, having an elastic insert placed between the stop elements of the posts and the barrier guide is known from the description of the Polish patent application PL.311384 . It is equipped with guiding elements enabling the barrier guide to move.
  • a road safety barrier is known from the description of the Polish invention PL.347197 , which has flexible load dampers arranged between the guide and the posts, each containing at least two coaxially fixed annular elements made of a material with elastic properties. There is a free space between the adjacent ring elements.
  • An absorbing element for a road safety barrier having the form of a bent thin-walled metal section having a first fastening wall having connecting means adapted to be fastened to the barrier fender, a second fastening wall substantially parallel to the first fastening wall and having connecting means adapted to be attached to the barrier post, and two deformation walls connecting the first fastening wall to the second fastening wall is known from the description of the Polish invention application PL.412418 .
  • each of the deformation walls of the absorbing element is inclined at an acute angle in the vertical plane, the orientation of the said angle of inclination being the same for both deformation walls, and the angle being in the range of 4 to 20°.
  • the absorbing elements feature a simple and economical structure and allow quick installation of safety barriers.
  • the aim of the invention was to provide such a safety barrier structure which will have the required/expected parameters at the lowest possible weight of barriers and low price of production.
  • the stiffness of the guide affects/impacts on the amount of load transferred to the adjacent/connected with posts - the stiffer the guide, the more posts take the transferred external load, thus the cross-section of the posts can be reduced or their spacing increased. Locating in barrier/installing two or more guides in parallel, according to the invention, increases the stiffness of the guides significantly. On the other hand, in the known solutions, single guide in barrier is used.
  • the invention is a barrier, while the characteristic element of said barrier is the use of A-type, B-type or 3n-type guides connected back-to-back/dorsally - coupled/combined with known fasteners such as, e.g. bolts, rivets, welds, etc. They can be joined together by any method known in the art, e.g. with bolts, rivets or other permanent methods.
  • the guides in the set are fixed/ arranged therefore in pairs. Between the guides, there may be additional filling element, element for stiffening or spacing elements/distance element/spacer known in the art. They can be located at a post or between posts.
  • the barrier may further comprise other guides or additional elements from the prior art.
  • the guide sets are connected to road posts.
  • At least one set consisting of two A-type or B-type or 3n-type guides, which are coupled with bolts or other elements, is mounted/combined to the posts driven into the ground of the shoulder or fixed to the load-carrying structure of the bridge.
  • the coupled guide it is possible for example to reduce the stiffness of posts or increase their spacing.
  • the guides should be connected/combined back-to-back/dorsally, but it is not required to be connected symmetrical. They can be asymmetric, i.e.
  • the filling and stiffening elements are located in the guides at the post or between the posts.
  • spacers are provided between the guides.
  • more than one set of guides (pair) is provided.
  • the proposed structure of the barrier made by the back-to-back connection of the guides has a stiffness many times greater than the stiffness of two guides placed next to each other. This solution increases the stiffness of the barrier in relation to the unconnected guides, with the same mass.
  • the embodiment shows the calculation results confirming the efficiency of the invention.
  • Figs. 1-3 show individual A-type, B-type, 3n-type guides used in the invention
  • Figs. 4-6 show A-type, B-type, 3n-type guides with posts.
  • Figs. 7-9 show A-type, B-type and 3n-type guides fixed to the road or bridge post according to the invention, i.e. in pairs.
