Description

  The present invention includes a covering member that is inserted between two rails of a track and whose upper surface is configured to be substantially flat, is installed so as to connect to these rails from the outside, and similarly, the upper surface is configured to be substantially flat. Covering members, which extend in the longitudinal direction of the track, each extending over several consecutive sleepers of the track and above the sleepers and the sleeper floor of the track. It is arranged perpendicularly from the sleepers and the sleeper floor, so that the static weight of the covering member inserted between the rails and the load that sometimes acts on the covering member is related to the side recesses of the rail. The present invention relates to a track covering member that is transmitted only to two rails by a mating support nose.

  Track coatings of the type described above are often provided to form rail-level traffic surfaces that are suitable for horse-traffic and pedestrians with respect to the track or track system. These track covering materials are suitable for, for example, railroad crossings and road vehicles, and at the same time, rails are installed, and also include traffic surfaces in large factory buildings or warehouse facilities. A track covering, including a cover member designed accordingly, is also provided to reduce the generation of noise caused by rail vehicles traveling on the rail.

  The principle on which the initially defined type of track covering is based, i.e. the covering member is connected to the sleeper so that the space between the two rails of the track is bridged in a self-supporting manner independent of the sleeper and sleeper floor. Positioned vertically above the sleeper floor of the track and from the sleeper floor of the track and the sleeper floor of the track, not only the load that sometimes acts on these covering members, but also the static weight of the covering member is tracked via the support nose. The principle of transmission only to the rails is very important for obtaining good operating characteristics of the track and maintaining these operating characteristics over a long period of time. In fact, significant dynamic loads are applied to the track by vehicles traveling in the region of the track covering, in particular rail vehicles. It should be noted that the elasticity of the track, which is largely determined by sleepers and other floors, will probably not change at all, or will change only slightly, depending on the track covering. By disposing the covering member vertically above the sleepers and the sleeper floor, the adverse effect of the track covering on the elastic behavior of the track is largely eliminated.

  In known track coverings of the type defined at the beginning, support noses that engage the rail side recesses, usually called “fishing surfaces”, are formed on the sides of the covering member. In order to prevent the covering members from resting on rail fasteners that are above the individual sleepers of the track and protrude higher above the edges of the rail legs, the covering members leave the space for the rail fasteners. Concave portions arranged corresponding to the intervals are provided. Therefore, it is necessary for the covering members manufactured in advance sequentially to arrange the track sleepers at equal intervals in the region of the track covering material. Existing tracks often do not follow this requirement, and it may happen even for newly installed track systems that this requirement is not necessarily met for structural and construction reasons.

  The object of the invention is to provide a track covering of the kind defined at the beginning, which can be installed in a simple manner, even on tracks where the track sleepers are not perfectly spaced from one another.

  The track covering of the type defined at the beginning is that the covering members extend in the direction of the sleepers, each being located above the gap between the sleepers arranged in succession, and each by means of an elongated connecting means It is mounted on a support member consisting of two connected support / positioning blocks, and these support / positioning blocks are rails on sleepers arranged at the maximum in the longitudinal direction of the track. The support / positioning block has a dimension corresponding to the net distance between the securing means, and the support / positioning block further includes a support nose formed on its side facing the rail to engage the side recess of the rail, The positioning block is positioned so that the connecting means provided in each support member engages adjacent recesses in the rail with which the support nose is associated with each other, for a length that matches the track dimension in the direction of the sleepers. The covering member placed on the support member is not displaced laterally on the support / positioning block of the support member by fitting, and the covering member inserted between the rails is in the direction of the sleepers. The support / positioning block is partially covered to extend to the flange groove of the track, and the covering member arbitrarily installed outside the rail extends to the vicinity of both rails. With this arrangement, it is possible to achieve the above-mentioned object completely in a structurally simple manner. The support member can be disposed above the space between the sleepers that are continuously arranged according to the actual position of each track sleeper, and it is not necessary to install the sleepers of the track at equal intervals. The arrangement of the covering member is not strictly restricted by the position of the sleepers, and is not restricted by the position of the rail fixing means provided on the sleepers. As is the case when a large error occurs due to the installation of sleepers, when the spacing between sleepers varies by an average value when viewed in the longitudinal extension direction of the track, usually use covering members having the same longitudinal dimension Can do. The length and shape of the covering member does not directly depend on the spacing existing between the continuously arranged sleepers of the track, so that a pre-manufactured pre-manufactured plate can be lengthened if necessary. It can be easily shortened, and therefore can be adapted to the situation of the intended installation location. Matching the shape of the covering member with the position of sleepers and rail fixtures required by known track coverings of the type mentioned at the beginning is no longer necessary for track coverings constructed in accordance with the present invention. The covering member of the track covering according to the invention is made in a relatively simple manner and can have a constant cross-sectional shape over its entire length, i.e. it forms a section of the profile and is therefore particularly simple and inexpensive Manufacturing becomes possible. In this way, covering members having various lengths can be obtained very simply by means of suitable split cutting, and thus can meet various requirements arising from different sleeper spacings without any problems.

  In many cases, in the track covering material, not only the space between the two rails of the track has to be covered by the covering member, but also the surface band-like portions connected on both sides and the outside of both the track rails. Must be covered by. In a manner similar to the construction of the space self-supporting covering between the two rails of the track, the covering of the two zone strips connected externally to the rail of the track is also in the direction of the sleepers. A support member comprising two support / positioning blocks, which are extended in a self-supporting manner above the gap between the consecutively arranged sleepers, and each connected by an elongated connecting means And a covering member is placed on the supporting member. The rail-side support and positioning block has a support nose and is supported on the rail by these support noses that engage the side recesses of the rail. The support / positioning block provided on the side away from the rail of the support member is supported on the cradle, and the support / positioning block located on the side away from the rail does not displace in cooperation with the cradle. It is preferable to do so.

  The covering member usually has the shape of a substantially closed plate with a few small openings, optionally provided, useful for attaching eg a hoist. However, it is also possible to provide a covering member in the form of a lattice if it allows liquids and particulates to flow undisturbed.

  A covering member placed on the support member and disposed between the track rails extends to the flange groove of the track, or forms an inner boundary of the flange groove, and is further optionally disposed on the outer surface of the rail The fact that the member extends to the immediate vicinity of the rail avoids the formation of undesirable openings between the support and positioning blocks arranged in succession. Such an opening would be undesirable because vehicles with narrow wheels are traveling on the dressing and people are walking on the dressing.

  In the assembled state, the covering member forms a stable structure with the support member, which is seen in the direction of the sleeper, while the covering member is securely fitted on the support / positioning block by fitting. Is held between the support / positioning blocks, and on the other hand, an elongated connecting member provided between the support / positioning blocks is formed below the support / positioning blocks. The support / positioning block transmits not only the load acting on the structure composed of the covering member and the support member but also the static weight of the structure on the rail by the support nose. Then, the positioning of the structure in the track and the positioning of the covering member on the support member are undertaken.

  The material suitable for the covering member and the support / positioning block is preferably concrete or a concrete composite composed of a particulate aggregate and a combined body. If desired, stiffeners may be used in these structural parts. As binders, not only various types of synthetic materials, but also cements and properties similar to cements are considered, for example synthetic materials like polyesters become a single binder or mainly cement or cementitious materials It may be useful to modify or add to the joint material based on. Some synthetic materials can also be combined to form a conjugate, and it is equally possible to combine some substances in a group of cement and cementitious material to make this conjugate. If it is desired to obtain a sound deadening or sound absorbing property of the track covering material, it may be advantageous that the small pieces contained in the composite material from which the covering member is made consist of a lightweight construction material, in particular a porous lightweight material. Advantageous materials include, for example, granular synthetic materials, granular slug fines, spherically calcined and expanded alumina particles, and similar calcined natural or artificial synthetic materials, and mixtures of such particulate materials are also contemplated. . Even fibrous fine pieces can be aggregated alone or in combination with other small pieces. In order to increase the edge strength and / or edge support capacity of the covering members and to obtain advantages in the manufacture and handling of the covering members, these covering members are made of metal or synthetic material if desired. A frame may be provided. The support / positioning block can be made entirely or partially (support nose) from a synthetic material, which can be a thermoplastic or thermosetting plastic or elastomer. The use of an elastomeric material has advantages with respect to shock absorption and ease of attachment of the covering material. Furthermore, it is beneficial if the covering member and / or the support / positioning block is provided with a reinforcement. In the latter case, it is advantageous to extend the reinforcement into the support nose.

  In track coverings constructed in accordance with the present invention, it seems very important that the covering member is well connected to the support member, this connection provides good long-term stability and if necessary. For example, it can be easily handled during installation of the track covering and to remove the track arbitrarily necessary for track maintenance so as to transmit a large load. Good fixing in the lateral direction can be obtained by fitting the covering member with the support / positioning block. In many cases, the static weight of the covering member, and optionally the surface pressure obtained by pressurizing the covering member, is sufficient to prevent the covering member from being lifted. Furthermore, and in an advantageous manner for attachment and removal purposes, the assembly of the covering member with the support member may comprise holding or fixing pins. These holding or fixing pins may for example be provided with threads or designed as socket pins.

  In order to obtain good adhesion between the covering member and the supporting member even in the vertical direction, the supporting / positioning block of the supporting member was formed in accordance with the undercut of the covering member at the place where they were connected to the covering member. The region has an undercut that engages. Thus, the good adhesion described above is achieved when the cover plate is connected to the support member in a structurally simple manner and with a simple operation.

  In order to ensure that the load acting on the covering member is transmitted well to the support member and to ensure an advantageous static load distribution that affects stability when the load is applied, On the opposite side, a step is formed in the shape of a tooth from the top, and the edge where the covering member faces the support / positioning block is formed in a shape of a tooth from the bottom so that it corresponds to the support / positioning block. Advantageously, a step is formed, so that the covering member rests on the step formed on the support / positioning block. The inward movement of the covering member-support member load transfer caused by this stepped configuration increases the load bearing capacity of the covering member or is advantageous in terms of its size for a given load capacity.

  Furthermore, it is advantageous if a longitudinal beam made of a flexible material, in particular an elastomer material, is inserted between the covering member and the block where the covering member is connected to each support / positioning block. It is. Such an embodiment of a track covering constructed in accordance with the present invention facilitates handling during the assembly of the covering member and the support member and allows transmission of vibration from the rail to the covering member. Since it is greatly reduced by the longitudinal bars of the flexible material, noise generated during traveling on the track is also reduced.

  With regard to the construction of the support members, in an advantageous embodiment of the track covering according to the invention, at least one support / positioning block provided on each support member leads from one of these blocks to the other. It is formed of a single rod or a single plate. Therefore, the connecting means provided on the individual support members are realized so as to require almost no space, and as a result, a relatively large space can be used for a thick wall stabilization structure composed of a covering member. This is particularly advantageous for achieving high load carrying capacity. Furthermore, the small space requirement of the connecting means designed as rods in the support member means that the support member remains in the track during subsequent track maintenance work, e.g. during subsequent track floor tamping operations. enable. For the operations involved during installation of the support member, it is further advantageous if each rod or plate is designed to be elastically flexible. By realizing fiber reinforced composites or steel rods or plates, high strength and good long-term stability can be achieved at low manufacturing costs. It is advantageous if the rod or plate reaches the support nose of the support / positioning block and forms a reinforcement.

  Another embodiment of a track covering constructed in accordance with the present invention that allows for the attachment of the covering to the track and the possible removal of the track in a particularly simple manner is provided on the individual support members. Further, the connecting means of the support / positioning block is made up of a plurality of pairs of half rods, and one half rod of one pair is connected to one support / positioning block of the support member, and the other of the pair Half rods are connected to the other support / positioning block of the support member, and the two half rods of each pair are hingedly connected to each other at opposite ends of the block. It is characterized in that the two half-rods form a fixed position where they are aligned with each other, while the two half-rods can be folded into a posture in which these half-rods are pointed. In this embodiment, the support member is inserted into the track so that the pair of half rods is folded, and then the half rods are pushed down to a position aligned with each other. The installation operation can be made particularly simple, so that the installation of the covering member on the support member can be carried out with the half rod already in a straight line or with the covering member on top. As the half rod is pushed straight down, it is connected to the support member. In the latter mode of operation, a preferred embodiment is that a tooth-like protrusion is provided on the inner surface of the support / positioning block, the tooth-like protrusion resting on the support / positioning block of the support member. In this state, it is characterized by engaging with the side surface of the covering member formed corresponding to these tooth-like projections and extending in the longitudinal direction of the track. This embodiment also makes it possible to mount the covering member very stably so that it cannot be lifted in a simple manner.

  The elastic support of the support nose provided on the support / positioning block enables the support member to rest on the track rail in a stable manner with structural tolerances balanced, thereby supporting the support / positioning block from the track rail. The transmission of vibrations up is greatly reduced. In this context, an embodiment in which the installation of the support member in the track can be realized in a particularly simple manner is that the support piece made of an elastic cushioning material, in particular an elastomeric material, has a recess in the side of the rail, Each support piece is inserted between a support nose provided on the support / positioning block, and each support piece is engaged with each recess.

  In the following, the invention will be described in more detail by means of exemplary embodiments schematically shown in the drawings. In the drawings, the same items are denoted by the same reference numerals.

  In the track shown in FIGS. 1 to 3 with one embodiment of a track covering 1 designed according to the invention, a covering member 5 is placed between the two rails 2, 3 of the track 4, 6 is placed so as to be connected to these rails 2 and 3 on the outside thereof. The covering members 5 and 6 have a substantially flat surface. The covering members 5 and 6 are mounted on a support member 14 that extends in the direction 15 of the sleepers and is located above the gap 16 between the sleepers 8 that are continuously arranged in the track. For the sake of clarity, in FIG. 1, the track 4 has no covering member in the sections a and d, the supporting member 14 in the section b, and all the covering members in the section c, that is, on the supporting member 14. The covering members 5 and 6 are respectively illustrated in FIG.

  The sleepers 8 of the track 4 are arranged at different intervals due to the rough tolerance of track work or special circumstances with complicatedly designed track sections.

  Each of the support members 14 respectively located above the gap 16 between the sleepers 8 arranged in series is connected by an elongated connecting means 18 and, when viewed in the longitudinal direction 7 of the track 4, at most, It consists of two support / positioning blocks 17 having a dimension 19 corresponding to the net distance between the rail fixing means 20 provided on the continuous sleepers 8. The support / positioning block 17 has a support nose 11 that engages with the side recess 10 of the rails 2, 3 on the side facing the rails 2, 3. Each of the assembled rails 2 and 3 is disposed in the adjacent recess 10 so as to be engaged with the connecting means 18 provided in each support member 14 by a length corresponding to the track dimension in the sleeper direction 15. Yes. The covering members 5 and 6 are placed on the support / positioning block 17 of the supporting member 14, and the supporting member 14 on which the covering members 5 and 6 are placed is above the sleepers 8 and the sleeper floor 9 of the track. And a covering member which is arranged at a distance from the sleeper floor in a vertical direction, thereby ensuring that the space between the two rails 2, 3 is bridged in a self-supporting manner. 5 and the static load of the covering member 5 and the supporting member 14 as well as the load sometimes applied to the supporting member 14 that supports the covering member 5 are supported by the support noses 11 engaged with the recesses 10 on the rail side portions. 3 only. The covering member 6 placed so as to be connected to the outer side of the rails 2 and 3 of the track is also mounted on the supporting member 14 in the same manner as the covering member 5, and one of the supporting / positioning blocks 17 of these supporting members 14. One of the support / positioning blocks 17 is provided on the side of the support member that is separated from the rail, and is engaged with the adjacent rails 2 and 3 by the support nose 11. It is supported. Furthermore, the space between the rails 2 and 3 of the track and the cradle 23 arranged on the outer member is bridged in a self-supporting manner by the covering member connected to the supporting member.

  In order to elastically support the support nose 11 of the various support members on the track rail, a support piece 12 made of an elastic material, in particular an elastomer material, is provided between the side recess 10 of the rails 2, 3 and the support nose 11. Has been inserted. Similarly, a flexible cross member 13 is inserted between the support / positioning block 17 and the base 23 on the side of the support member that supports the covering member 6 on the side away from the rail.

  The covering member 5 arranged between the rails 2 and 3 extends until it reaches the flange groove 30 of the track by partially covering the support / positioning block 17 in the sleeper direction 15 and on the outside of the rails 2 and 3. A certain covering member 6 reaches very close to the rails 2 and 3. In this way, although not preferred, the opening is prevented from being formed in the rail region.

  The covering members 5 and 6 are placed on the upper side of the support / positioning block 17 of the supporting member 14 disposed below the covering member, so that the stepped shape engagement (fitting) is performed on the supporting member with which the covering member is assembled. To prevent lateral displacement. The support / positioning block 17 of the support member 14 has an undercut 31 in which a region 32 of the covering member 5, 6 formed in accordance with the undercut 31 is engaged at a place where they are connected to the covering members 5, 6. Thus, the covering members 5, 6 are also prevented from being lifted from the support member.

  The connecting means 18 of the support / positioning block 17 provided in the support member 14 is composed of a rod 33 extending from one block 17 to the other block 17. Such a rod 33 may be replaced with a thin plate. This rod or alternatively provided plate is preferably designed to be elastically flexible, thus facilitating the combination of the covering member with the support member. This is because the support / positioning block 17 having the above-described undercut has a rod 33 so that the covering member region 32 formed in a shape corresponding to the undercut can be easily inserted between the undercuts 31. Or by pushing up the center of each appropriately designed plate, the undercut is turned slightly in the opening direction during installation, after which the center of the previously lifted rod 33 is released and the undercut This is because 31 and the region 32 are securely engaged.

  Depending on the material for each of the covering members 5, 6 and the block 17 of the support member 14 and the requirements set for each of these members 5, 6, 14 in many cases, as shown in FIG. Advantageously, the covering member 5 is provided with a reinforcing material 28, and / or the covering member 6 is provided with a reinforcing material 29 and / or the block 17 is provided with a reinforcing material 39. Such stiffeners are also provided in other embodiments, for example the embodiments shown in the remaining drawings. The reinforcement can be designed, for example, in the form of rods or grids made of metal or synthetic material or in the form of fibres. Often, no reinforcement may be provided.

  In the modification shown in FIG. 4, the support / positioning block 17 of the support member forms a step 27 on the block 17 by the tongues 26 from the top in the shape of the tongues on the side opposite to the rails to be assembled. Corresponding to the support / positioning block 17, the edge facing the support / positioning block 17 has a stepped shape from the bottom to the tongue-like shape. It is on the step 27 formed by the positioning block 17. In the example illustrated in FIG. 4, no undercut is provided, and the covering members 5, 6 are provided, for example, in a retaining pin 24 with a thread 25 and meshing with a corresponding female screw, or in a block 17. Are not lifted by screw nails (not shown). A variation would be a socket pin. Since the covering members 5 and 6 are placed on the step 27 provided on the inner side of the support / positioning block, the supporting width of the covering member 6 is reduced, so that the covering member 6 can withstand a large load and / or Lighter dimensions can be achieved for a given load carrying capacity.

  The modification shown in FIG. 5 is intended to have a structure similar to that of FIG. 3, but in this case, a crosspiece 36 made of a soft and flexible material, in particular an elastomer material, is used. , 6 and the respective support / positioning block 17, the covering members 5, 6 are inserted at locations where they are connected to the block 17. This facilitates the assembly of the covering member with the support member, and the seating of the covering member on the support member is also improved by such a crosspiece.

  In the modification shown in FIG. 6, the entire support / positioning block 17 is made of a synthetic material, and a dimensionally stable elastomer material is particularly suitable for its end. The rod 33 constituting the connecting means of the support member extends to the support nose 11 of the support / positioning block 17. In this case, the covering members 5 and 6 are merely placed on a support / positioning block having no undercut, and the transmission of the load occurring at the top of the block 17 and the covering and supporting members 5 and 6 are supported / positioned. The side frictional force acting between the blocks 17 prevents the covering members 5 and 6 from lifting together with the static weight of the covering members 5 and 6. Reinforcing material is provided if desired.

  In the modification of FIG. 7, the shape of the region in which the covering members 5, 6 and the support / positioning block 17 of the support member 14 supporting these covering members operate cooperatively is the side of the support / positioning block 17. Following the undercut 31, the inner surfaces of each side of these blocks 17 extend freely downward, so that usually the covering member is joined to the support member, in the process the region 32 of the covering members 5, 6 is above the block 17. 3 is selected to be similar to the shape of the embodiment of FIG. 3 except that the process is simpler when engaged with the undercut 31 provided in FIG.

  In the modification of FIG. 8, there is a shape similar to the shape shown in FIG. 3, but the undercut 31 is designed to have a semicircular cross section, and on the other hand, it is formed corresponding to the undercut. The stability and durability of the region 32 provided on the edges of the covering members 5, 6 is increased, and on the other hand the procedure involved in joining the covering member and the support member is facilitated.

  In the embodiment shown in FIGS. 9 and 10 of a track covering designed in accordance with the present invention, the support member 14 assigned to the covering member 5 disposed between the rails 2 and 3 of the track is a support / positioning block. The connecting means 18 is composed of a pair of half rods 33a, 33b between 17 members. One half rod 33a of the pair is one of the support / positioning blocks of such a support member, and this other pair of semicircular rods 33b is the other of the support / positioning block of the support member, respectively. It is connected. The two half rods 33a and 33b of each pair are connected to each other in a hinge shape at the end opposite to the support / positioning block, and the two half rods 33a and 33b are shown in FIG. Can be folded into a pointed posture and lifted. In this way, the support member 14 can be most easily inserted between the track rails 2 and 3 by being folded and lifted to the pointed posture shown in the drawing, and subsequently the half rods 33a and 33b. As shown in FIG. 10, by being pushed down in the direction of the arrow 22, they can be moved to positions that form a straight line with each other. The hinge connection 34 is designed to form a fixed position at a position where both half rods are aligned with each other as shown in FIG. Depending on the shape of the cooperating surface of the covering member and the support / positioning block, connecting the covering member 5 to the support / positioning block 17 of the support member 14 will be pushed down to a position where the half rods are aligned with each other. Or after reaching positions that are aligned in a straight line. When undercut engagement occurs, the covering member joins the support member as the half rod is depressed. This also applies to the configuration shown in FIGS. 9 and 10 in which the tooth-like protrusions 37 are provided on the inner surface of the support / positioning block 17, and these tooth-like protrusions 37 are formed corresponding to these tooth-like protrusions. The cover member 5 is on the support / positioning block of the support member 14.

  Each of the edges 35 of the covering members 5, 6 extending across the rail is located extending above the support member 14, as is apparent from FIG. 1, which means that two adjacent covering members Since these are mounted on one support member in common, it is ensured that the continuously disposed covering members are in good contact.
