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 EP publication. 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 patent. 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 splices and which also comprise reinforcement hoops 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.
  • hoops Such reinforcement by hoops would not be suitable for making hoses of safety rails because it necessarily includes hoops and ends of rods in relief above and below the heddles, which would be very dangerous. for the safety of vehicle passengers.
  • hoops that compress the wood cannot be used outside because the swelling of the wood due to humidity variations would cause the hoops to loosen, which would become inoperative.
  • 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.
  • 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 bolts for fixing the fishplates and on the same side as the junction between the two nearest logs and which cross the horizontal diametral plane of the log.
  • the metal reinforcing rods are threaded rods or bolts.
  • the reinforcing rods are vertical.
  • 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.
  • Figure 1 is a perspective view of a slide section according to the invention which is composed of round wooden posts 1, carrying a horizontal rail 2, which is composed of wooden logs 31, 32 ... etc .. ., which are assembled end to end by two horizontal metal fishplates 41, 42, placed on either side of the ends of the two logs and connected together by bolts 5, which are placed in the diametrical horizontal plane of the logs and which cross both the fishplates and one of the logs.
  • 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 beam 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 located 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 compressive force makes a large part of the fibers of the solid wood, so that they also participate in the resistance of the wood.
  • Figures 4 and 5 respectively show a perspective view and a cross section of a second embodiment in which the butt connection of two logs is reinforced by four rods or vertical bolts 8, which form two pairs symmetrical with respect in the vertical diametral plane of the logs, each pair being placed in contact with or in the immediate vicinity of one of the two bolts 5 passing through each log and always on the same side thereof as the end of the nearest log.
  • Figures 6 and 7 respectively show a perspective view and a cross section of a third embodiment of the invention.
  • the butt connection between the ends of two logs 3 is reinforced by six vertical rods or bolts 8 at a rate of three per log, namely a pair of rods 81 and 82 which are placed in contact with or near immediate of one of the two bolts 51, symmetrically with respect to the vertical diametral plane and a single rod 83 which is placed in contact with or in the immediate vicinity of the second bolt 52, which is preferably the closest to the junction of the two logs , in the vertical diametral plane.
  • Figures 8 and 9 respectively represent a perspective view and a cross section of a fourth embodiment of the invention.
  • each assembly between the ends of two logs is reinforced by eight rods or vertical bolts 81, 82, 83 84, at the rate of four passing through each log.
  • These four rods form two pairs, each pair being placed in contact with or in the immediate vicinity of one of the two bolts 51 and 52, symmetrically with respect to the vertical diametral plane.
  • the spacing between the two rods 81 and 82 of a pair is different from the spacing between the two rods 83 and 84 of the other pair, so that the forces are distributed over a greater part of the surface of the log and the stresses in the wood are therefore reduced.
  • the two rods 83 and 84 of the pair closest to the junction of the two logs are closer together than the other two rods 81 and 82.
  • the rods 8 are represented only by their axis in FIG. 9.
  • Figures 10 and 11 respectively represent a perspective view and a cross section of another embodiment of a slide according to the invention.
  • the tensile strength of the slide is strengthened by equipping it with two identical heddles 2 and 2 ′ superimposed and connected together, such so that their tensile strengths add up.
  • Each stringer is made up of logs assembled end to end.
  • the two fishplates 41 and 4′1 located on the side of the road are identical to those which are used in the embodiments according to Figures 1 to 9 comprising a single stringer.
  • the assembly is reinforced by vertical metal rods or bolts 10, which are incorporated into the logs and placed in contact with the bolts 5 and 5 'or in the immediate vicinity of these and which are engaged in vertical channels drilled in the advance in the logs.
  • Figures 10 and 11 show an embodiment in which there is associated with each bolt 5 and 5 ′ a single metal rod 10 placed in the vertical diametral plane.
  • each metal rod 10 passes through the two superimposed logs 3 and 3 ′ and therefore constitutes a mechanical connection between the two superimposed healds which makes them integral in the event that a tensile force is exerted on only one of the two healds.
  • the end-to-end assembly between the two rails comprises at the rear a single plate 9, which replaces the two rear bars 4isses and 4′2 and which is connected by the bolts 5 and 5 ′ to the two front bars 41 and 4′1.
  • the plate 9 has the same length as the ribs 41 and 4′1. Its height is slightly greater than the distance separating the horizontal diametrical planes from the two beams. The plate 9 has the effect of strengthening the mechanical connection between the two superimposed healds.
  • the impact resistance of the beams is improved, so that more logs can be used. long and reduce the number of connections between logs.
  • This additional post 11 may include a mechanical connection with the beams. It serves to support these in the event of a vehicle impact against the beams.
  • Figures 12 and 13 respectively represent a perspective view and a cross section of a second embodiment of a slide having two superimposed healds 2 and 2 'made integral by a plate 9 acting as a joint bar joint to butt joints end of the two rails.
  • FIGS. 12 and 13 there is shown in FIGS. 12 and 13, a plate 9, the internal face of which comprises metal studs 7, which penetrate into the wood.
  • FIGS. 12 and 13 differs from that according to FIGS. 10 and 11 by the number of reinforcing rods used which is for each log end of two pairs of vertical rods 101, 102, 103, 104 instead of two rods 10 only.
  • the length of the rods is limited to the height of a log, so that the rods 101, 102, 103, 104 reinforcing the log are separated from the rods 10′1, 10′2, 10 ′ 3, 10′4 reinforcing the log placed below the previous one as seen in Figure 13, which avoids having to engage the same rod in two channels which may be misaligned.
