Definitions

  • the present invention relates to round wooden safety barriers intended to be placed along roads or motorways and to a method of construction thereof.
  • the technical sector of the invention is that of the construction of road safety devices.
  • the present invention relates to improvements to the crash barriers described in this publication EP.A. 0.228.334.
  • the wooden slides must meet specifications which impose a determined tensile strength for the healds assembled, for example a resistance of 200 kilonewtons (20 T.), so that in the event of a vehicle impact, the healds do not are unlikely to separate, allowing the vehicle to pass through.
  • the problem is therefore to improve the safety barriers comprising a round wooden beam assembled end to end, so as to improve the static tensile strength of the assemblies between beams by using simple and inexpensive reinforcement means, so that the price of wooden slides remains competitive.
  • the objective of the present invention is therefore to improve the end-to-end assemblies between logs to give them a high static tensile strength while allowing in the event of a vehicle impact, a significant elongation of the assemblies located on either side. else shock.
  • the BE.A. 883.394 (Yves DURAND) describes butt joints between beams of rectangular section which comprise on the one hand assembly bolts which pass through several juxtaposed beams or which pass through a beam and two junction fishplates and which also comprise hooping reinforcement composed of two plates which are clamped against the fields of each beam, at the end thereof, by threaded rods which pass through the beam and which are perpendicular to the assembly bolts. Such reinforcing hoops compress the wood located in the areas stressed by the assembly bolts.
  • the road safety barriers according to the invention are of the known type, comprising wooden posts, which are assembled end to end by two metal fishplates, connected together by bolts which pass through said fishplates and said logs and which are located in the horizontal diametral plane of these at least one of said fishplates, preferably at least the fishplate located on the side of the road, being placed in a horizontal groove of the logs.
  • each assembly between two successive logs is reinforced by incorporating in each log metal rods which pass through it, which are placed at the contact or in the immediate vicinity of the fastening bolts of the fishplates and on the same side as the junction between the two nearest logs and which cut across the horizontal diametral plane of the log, the metal rods being provided with a head placed in a housing dug in said log.
  • the metal reinforcing rods are threaded rods or bolts comprising a nut placed in a housing hollowed out in said logs.
  • safety barriers comprising two identical slides superimposed in contact with one another, which are mechanically connected together by a single plate, located on the opposite side of the road, which is connected by horizontal bolts with two fishplates located on the side of the road.
  • assemblies between successive logs of each stringer can also be reinforced by vertical metal rods associated with each bolt.
  • each vertical rod can pass through two superimposed logs so that it participates in the mechanical connection between the two superimposed healds.
  • the invention results in wooden road safety barriers, whose tensile and impact resistance is significantly improved by the addition of reinforcing rods incorporated in the logs, that is to say by means little expensive in material and in installation work.
  • the channels intended to receive the reinforcement rods can also be drilled in the factory at the same time as the channels intended to receive the joint bolts of the fishplates and the reinforcement rods can be laid on the site at the same time as the bolts. assembly. We can provide a maximum number of channels and set up a number of reinforcing rods adapted to the specifications of each particular use.
  • the embodiment comprising two beams superimposed on contact with each other, which are mechanically linked in all cases by a common assembly plate and possibly by reinforcing rods which pass through two superimposed logs makes it possible to construct slides.
  • made of wood with high mechanical properties and, in particular, very good tensile strength and reduce the number of assemblies and therefore also the cost of construction.
  • each assembly comprises four bolts 5 at the rate of two for each log.
  • the logs 31, 32 have a constant diameter and the splint 41 is placed in a horizontal groove of the logs.
  • the posts 1 are placed at the junctions between two logs 3 and the rail is assembled with the posts 1 by bolts 6 which pass through the rear splint 42 and the post 1 as can be seen in FIG. 3.
  • Fishplates 41, 42 may have, on their internal face, metal studs 7 which penetrate into the wood.
  • connections between logs must be strong enough so that they do not risk breaking when a vehicle launched at high speed strikes the beam.
  • the beams must resist a tensile force of around 200 kilonewtons (20 T.).
  • the end-to-end assemblies of the heald elements are reinforced by incorporating metal rods 8, which have a diameter of the same order as that of the bolts 5, into the ends of each log.
  • the rods 8 are advantageously threaded rods or bolts.
  • Each rod 8 crosses a log right through.
  • Each rod 8 is placed in contact with or in the immediate vicinity of a bolt 5 and on the same side thereof as the most adjacent junction between two logs, that is to say the junction in the assembly of which participates the bolt 5, so that when traction is exerted on the ribs, each bolt 5 is driven towards the rod 8 which is associated with it.
  • the rods 8 intersect the diametrical horizontal plane in which the bolts 5 are located.
  • the figures represent preferred embodiments in which the rods 8 are vertical and therefore perpendicular to the horizontal diametral plane of the logs.
  • rods 8 could be inclined relative to the diametral horizontal plane, but in all cases, they overlap the latter, that is to say that they are not parallel to the bolts 5.
  • FIG. 1 represents a first embodiment in which, with each bolt 5, is associated a single vertical metal rod 8, which is placed in the vertical diametral plane of the logs 3.
  • Figures 2 and 3 are cross sections of Figure 1.
  • the rods 8 are wood bolts.
  • the head 8a of the bolt and the nut 8b screwed onto the bolt are placed in a housing hollowed out in the log, so that they do not protrude outside of the latter.
  • the bolt 8 is housed in a channel drilled through the log.
  • the bolts 5 bear against the rods 8, which themselves bear against the wood by distributing the forces, so that the fibers of the wood situated in the diametral plane vertical also participate in tensile strength.
  • the rods 8 tend to bend, which has the effect of strongly applying the head 8a and the nut 8b against the wood and of compressing the latter and this compression force makes it large part of the fibers of the solid wood, so that they also participate in the resistance of the wood.
  • reinforcing rods according to the invention can be oblique to the horizontal plane and do not clamp the wood which illustrates the difference with rods intended to clamp two frets applied against the upper and lower faces of a smooth.
