Definitions

  • the invention relates to a plastic lane separator block intended in particular to delimit traffic lanes, in particular during work that can be carried out on the roadway.
  • the invention aims to solve these problems and proposes for this purpose that the separator block which is therefore hollow internally and is provided at its base with a bottom, be reinforced by at least one hollow internal pillar standing apart longitudinal and lateral outer walls of the block, while being locally connected to these said longitudinal walls, in the upper part.
  • this pillar will end, on the side opposite the bottom from which it rises, by a transverse "top” wall connected laterally to said external longitudinal walls of the block, via short connecting partitions, isolated from the outside, thus extending laterally the transverse wall in question.
  • the figures therefore show a block or block separating tracks, made of plastic material which can in particular be manufactured by rotational molding and intended for use by road services or in particular by public works companies.
  • the separator block 1 is in the present case in the form of a wall element of approximately 70 cm in height and 100 to 110 cm in length.
  • the element 1 can be equipped in the upper part with passages 12 which pass right through it to lead to its external longitudinal walls 3, 5. These passages can be dimensioned to receive the forks of a carriage Handling.
  • a semi-cylindrical channel 14 could be formed in the upper transverse wall 12 'of each passage, thus allowing the installation of a bar or any other lifting rod.
  • the block 1 will preferably be made of plastic, such as medium density polyethylene.
  • the longitudinal walls 3, 5 will advantageously, and as illustrated more clearly in Figures 1 and 3, be inclined to give the block in vertical cross section ( Figure 3) a shape flaring from the top towards the base where the block is provided with a substantially horizontal bottom panel 13, as illustrated in FIG. 2.
  • the block in vertical transverse section, may have substantially the shape of a trunk of a pyramid.
  • these longitudinal walls 3, 5 may have a double slope with a more pronounced flare in the lower part 1a than in the upper part 1b of the block, a substantially horizontal junction line 15 externally showing the connection of the slopes of each side of the block, for example about halfway up.
  • FIGS. 2 to 4 Let us now focus more specifically on FIGS. 2 to 4 to note that in the bottom 13, a sort of central hollow well or pillar 17 is arranged, the role of which is to internally reinforce the block and more particularly to stiffen its external longitudinal walls 3 and 5.
  • the hollow pillar which therefore rises towards the inside of the block from the bottom 13 with which it comes, is locally connected to said walls 3 and 5, so that the forces undergone by these walls can be transmitted and absorbed by the walls of the pillar, which in this case comprises four side walls 19 forming a trunk of a pyramid and closed at their top by a continuous transverse wall 21.
  • the rigidity of the pillar will be ensured and its side walls may extend away from the longitudinal walls opposite the block with which there will be connection at the location of the zones 23 located at the transverse wall of vertex 21, the latter thus forming a retaining veil in thrust and a "direct" transverse connection between the two opposite walls 3 and 5 of the block (see FIG. 3).
  • connection zones 23 may be formed not by simple lines but by short partitions slightly inclined relative to the horizontal and extending the wall 21, so that the lines of junction 25 between this top wall 21 and the side walls 19 of the pillar are located slightly away from the outer longitudinal walls 3 and 5 of the block.
  • the opposite lateral walls of the pillar substantially parallel to the walls 3, 5 of the block will then be extended by the sections of practically vertical walls 27 coming to join together the walls in question of the block and the pillar between the slope connection zone 15 and each partition 23.
  • blocks containing several hollow stiffening pillars distributed from place to place along their longitudinal walls and having an appropriate height depending on the position of the areas to be reinforced.
  • provision could be made to add partitions to the pillar (s), in particular by adding transverse walls such as 19, 21 acting as bracing elements.
