Definitions
- the present invention relates to a support for railway rails, of the type including railroad cross member, comprising a central core of parallelepipedal appearance formed of at least two juxtaposed blades made of solid wood or materials based on wood, and a protective envelope encasing said central core, said protective envelope being made in one piece, and being formed of a peripheral wall having at least two opposite upper and lower faces and two opposite lateral faces, designed to match at least the four longitudinal faces of the central core, as well as at least one internal partition extending between two opposite faces or two contiguous faces of said peripheral wall and delimiting with the peripheral wall of the casing of protection of at least two cells each having a shape complementary to a blade of said central core.
- the rail supports also called railroad supports, concerned by the present invention, such as railway sleepers, bridge parts, engineering structures and timber. devices, participate in the construction of railways, in which, once anchored in a ballast, beyond serving as a support for the rails, are intended to ensure a constant distance between them and to distribute the mechanical loads on the ballast when passing a convoy.
- creosote To increase their lifespan, it has thus been proposed to impregnate the supports of wooden railway rails, by definition putrescible, with a protective substance such as creosote, intended to mitigate biological attacks from in particular xylophagous agents, such as fungi and termites.
- a protective substance such as creosote
- creosote is currently under strong contestation because of its adverse effects on the environment and human health.
- the constantly evolving regulations to which the use of this substance is subject also suggests that it is doomed to phasing out.
- Concrete rail supports are advantageous in terms of cost, but they prove to be heavy, complex to handle, and fragile due to their rigidity. In addition, they are non-machinable and require an elevation of the ballast, which is synonymous with additional costs. Finally, concrete railroad track supports have a high carbon footprint.
- the steel track supports have a long service life. However, they generate noise when trains pass, which limits the areas where they can be used. Their high electrical conductivity and their high maintenance cost, in particular because of the corrosive risk, are also limiting.
- plastic or composite material track supports are, like those made of wood, machinable and recyclable, absorb vibrations and therefore noise. Nevertheless, technical constraints remain, such as their dimensional variations, caused by thermal expansion of their constituent material. In addition, the latter may be subject to a creep phenomenon over time, which risks compromising the pull-out resistance of the lag bolts. Also, the cost of plastic or composite material track supports is high, which constitutes an additional brake on their deployment.
- the object of the present invention is to provide a support for railroad tracks, such as in particular a railroad tie, of the type consisting of a central core made of wood or wood-based materials covered with a protective envelope, having an alternative structure to those already described, making it possible both to overcome all of the drawbacks mentioned above and to improve its longevity in the face of the effects of the weight of the convoys traveling on the railway tracks, while responding the technical, budgetary and environmental criteria currently in force. More precisely, the object of the present invention is to provide a support for machinable railway rails, the service life of which is extended compared to existing rail supports, which is environmentally friendly, and whose structure and constituent materials allow easy recycling.
- the present invention relates to a support for railway rails of the type indicated in the preamble, characterized in that said blades comprise a plurality of slots formed through their thickness e and in that the slots of each blade are connected to the lights of the adjacent blades by pins of plastic material filling said lights.
- said protective envelope is made of plastic material.
- said protective casing further comprises a pair of caps designed to cover the left and right end faces of said central core.
- the present invention has also provided that the upper face of said protective casing comprises at least two recesses extending symmetrically on either side of a plane passing through the center of said protective casing and s 'extending perpendicular to its longitudinal axis.
- the recesses have threaded holes.
- the peripheral wall of said protective envelope may have a structure forming a set of reliefs and hollows extending over at least a portion of the underside of its peripheral wall.
- the structure forming a set of reliefs and hollows can also extend over at least a portion of the opposite side faces of the peripheral wall of the protective casing, said portion extending from the face. lower part of the peripheral wall towards its upper face.
- the present invention has also provided for the characteristic according to which said blades are each formed from a series of abutting strips. According to a possible variant embodiment, said blades extend parallel to each other and parallel or perpendicular to the upper and lower faces of the peripheral wall of the protective casing.
- FIG.1 corresponds to a perspective view in transparency of an alternative embodiment of a rail support according to the invention, defined here by a railroad tie,
- FIG.2 is a perspective view of the central web of the railway sleeper of Figure 1,
- FIG. 3 corresponds to a cross-sectional view of the railway sleeper of Figure 1, taken at an alignment of through-holes formed by the blades of the central web along one of their transverse edges,
- FIG.4 illustrates a partial side view of the railway sleeper of Figure 1
- FIG. 5 is a cross-sectional view of a second alternative embodiment of the rail support according to the invention.
- FIG. 6 is a cross-sectional view of a third alternative embodiment of the railway rail support according to the invention.
- the rail support according to the invention is defined by a railroad cross member 1 comprising on the one hand a central web of parallelepipedal appearance 2, and of on the other hand a protective envelope 4 enveloping said central core 2.
- the latter is here formed of four blades 3, of thickness e, made of solid wood.
- the blades 3 are formed each of a series of wooden slats assembled together, for example by their respective lateral edges, or by their respective longitudinal edges or face to face after superposition.
- the different blades 3 of the central core 2 can each be made from different types of wood.
- a central core 2 comprising three internal beech slats, sandwiched between two external oak slats 3, a material by definition more durable and resistant than beech.
- the protective casing 4 is advantageously in one piece, and is made of plastic or thermoplastic material, loaded or not with fibers and / or talc, through a process known per se, such as for example a plastic injection, extrusion or “ejection” (registered trademark) process.
- the protective casing 4 is formed of a peripheral wall preferably having a thickness el of between 5mm and 15mm. It has two opposite faces, upper 6 and lower 7, and two opposite lateral faces 8, 9, designed to match at least the four longitudinal faces of said central core 2, as well as two left and right end faces 11, 12, designed to cover the left and right end faces of the central web 2.
- the protective casing 4 also comprises three internal partitions 13 parallel to each other, extending between its two opposite lateral faces 8, 9, parallel to its upper 6 and lower faces 7.
- the partitions internal 13 have a thickness e2 of between 3mm and 10mm and delimit, with the peripheral wall of the protective casing 4, four cells 14 each having a shape complementary to a blade 3 of the central core 2.
- each wooden strip 3 of which the central core 2 is made is housed in an individual protective sheath, defined each time by a cell 14 , and is thus completely separated from the other blades 3.
- the blades 3 comprise a plurality of slots 30, formed through their thickness e, and, in the variant embodiment illustrated in Figure 2, such that each lumen 30 of a blade 3 is aligned with a corresponding lumen 30 of the adjacent blade (s) 3.
- These slots 30 are filled with the plastic or thermoplastic material used to coat the blades 3 of the parallelepipedic core 2 by the protective casing 4, during the manufacture of the railway sleepers 1, for example by an injection process. plastic, extrusion or "ejection" (registered trademark).
- the blades 3 are therefore not only each coated with an individual protective sheath, but also interconnected by pins 31 of plastic material filling said openings 30. This last characteristic makes it possible to prevent the blades 3 from being do not move with respect to each other within the protective envelope 4, in particular under the effect of the weight of the convoys traveling on the railway tracks.
- the slots 30 are preferably aligned along the longitudinal edge 18 and the transverse edge 19 of each of the blades 3 and so as to be located at a distance dO between 5mm and 40mm from the longitudinal edge 18, and at a distance dl between 5mm and 70mm from their transverse edge 19. Furthermore, the slots 30 of the same blade 3 are regularly spaced from one another, preferably by a distance d2 of between 50mm and 200mm.
- the upper face 6 of the protective casing 4 comprises two recesses 15 extending symmetrically on either side of a plane passing through the center of the protective casing 4 and extending perpendicularly to its longitudinal axis X.
- the two recesses 15 are for example produced by machining and are designed to each accommodate a metal saddle (not shown) intended for fixing a rail.
- they are provided with threaded holes 16, extending through the blades 3 and the internal partitions 13 of the protective casing 4, intended to accommodate screws for fixing the metal saddle in the recesses 15.
- each recess 15 has a specific inclination to allow the reception of a fixing saddle in accordance with the French standards in force.
- the bottom 17 of the recesses 15 could have an inclination different from that illustrated and extend for example horizontally in order to be able to accommodate other types of fixing saddles.
