Description

Technical Field

[0001] A railway track, particularly a block assembly and a kit for laying the track, and a method for installing the block assembly. Prior Technology

[0002] Traditional railway tracks are secured using sleepers and rail fasteners. Sleepers provide support, and rail fasteners secure the rails to them; typically, monolithic sleepers are used. Typically, a monolithic sleeper spans the width of the track, that is, the distance between the rails (perpendicular to the direction of travel).

[0003] Railway sleepers necessarily require two pairs of rail fasteners to be installed parallel to each of the two rails. For certain rail configurations, more flexibility in track layout is needed. For example, subway tracks have a unique gauge and a more compact turning radius (among other considerations). Therefore, direct-fixing blocks are often used.

[0004] Direct-fixed blocks provide similar support to integral railway sleepers. However, unlike integral railway sleepers, direct-fixed blocks are arranged in pairs, with each pair providing the ability to adjust track width (gauge) and different turning radii.

[0005] The direct-fixing blocks are initially placed on a concrete slab and then partially embedded in the poured concrete (or other material). Rail fasteners can then be attached to the embedded direct-fixing blocks. This arrangement provides configurability and stable fixation.

[0006] However, as disclosed herein, existing direct fasteners have many problems. To address these problems, this paper discloses a technical solution involving direct fasteners. Summary of the Invention

[0016] The various aspects will be described in detail with reference to the accompanying figures. Where possible, the same drawing markings are used in all drawings to refer to the same or similar parts. References to particular examples and implementations are for illustrative purposes and are not intended to limit the scope of the claims.

[0017] As mentioned above, the integral layout used for railways is under-optimized for layouts that require more configurations. Typically, integral blocks are custom-made for the layout. However, this process increases the cost of setting up and introduces unnecessary construction delays. In addition, any adjustments to the arrangement often require rework of the integral blocks and other components of the rail. Therefore, direct fixed blocks can be used to address defects in integral block-related layouts.

[0018] Different gauge gauges can be adapted by direct fixed blocks spaced apart according to the desired rail moment. For example, subway rails can have narrower gauge than heavy freight rails. However, direct fixed blocks can be used in both configurations. Unlike integral blocks, the track can be adjusted in the field since each direct-fixed block is independent. Another motivation for the use of directly fixed blocks is to address configurations that require different turning radii. For example, subway rails can have a smaller turning radius than that of heavy freight rails.

[0019] An advantage of directly securing blocks is the ability to adjust the layout in the field. As mentioned above, custom gauge and turning radii may be required. To the extent these aspects are altered, direct fixed blocks often do not require customization for a specific block when compared to the arrangement associated with the integral block. In addition, furnishings associated with integral blocks often require brand new integral blocks, which need to be ordered and shipped to the site for furnishing.

[0020] However, directly anchoring blocks is not without its challenges. When directly anchored blocks are placed on a concrete slab, they are subjected to numerous forces. These forces can damage, displace, and / or destroy the blocks (and any attached hardware components). If the blocks are subjected to such forces, there is a risk that the rails will lose support, potentially leading to derailment of locomotives and rolling stock. Such incidents can result in property damage and even loss of life.

[0021] To secure and protect the blocks, one or more layers of concrete are poured around them to anchor them to the concrete slab. The poured concrete typically reduces the forces required to move and / or remove the blocks from the base layer (i.e., the slab). Furthermore, the poured concrete protects the blocks from weather, mechanical damage, and other factors. However, existing direct-fixing block configurations lack sufficient design to properly secure the blocks in place.

[0022] There is also a risk that the extended sections of the reinforcing bars may corrode. When the reinforcing bars corrode, as the corrosion spreads throughout the metal, the internal reinforcing bars may also begin to corrode.

[0023] In stark contrast, as described above, the technical solution of this disclosure includes a reinforcing steel assembly that is completely contained within the block itself. By ensuring that the reinforcing steel is entirely within the block, there are no external components that could corrode the steel. Therefore, external corrosion will not penetrate into the block by traveling along the extension of the reinforcing steel.

[0024] External reinforcing bar extensions may be damaged and break directly. As mentioned above, corrosion is a factor that damages and / or weakens the reinforcing bar extensions. When the reinforcing bar extensions break, the block loses its integral connection with the poured concrete, resulting in unstable block support.

[0025] In stark contrast, the technical solution disclosed herein includes reinforcing steel assemblies that are entirely contained within the block itself. Therefore, the reinforcing steel assemblies will not break or lose their integral connection with the poured concrete. The block assemblies are designed so that, due to the unique characteristics of the technical solution disclosed herein (as disclosed below), the poured concrete firmly secures the block.

[0026] Furthermore, extended sections of reinforcing bars are difficult for installers to handle. These sections may be sharp, or even if in good condition, rough and prone to causing injury. Additionally, these extended sections must be carefully handled before pouring concrete to avoid any premature damage. Even when blocks with extended reinforcing bars have been placed, pouring concrete can still damage them. Even under ideal conditions, these factors slow down the installation process. Worse still, these problems pose a risk of injury to installers.

[0027] As described, the technical solution of this disclosure includes a reinforcing steel assembly completely contained within the block itself. Since no reinforcing steel extends from the disclosed solution, personnel will not be injured by the steel. Furthermore, personnel can easily handle the block without the risk of damaging any protruding portions of the reinforcing steel. Therefore, the technical solution of this disclosure protects personnel from unnecessary occupational hazards. Additionally, installation personnel do not need to worry about prematurely damaging the protruding portions of the reinforcing steel, because, as mentioned above, the reinforcing steel in the technical solution of this disclosure is completely contained within the block.

[0028] Additionally, there is a risk of interference between the extended steel reinforcement sections and other track components. For example, conduits for cables may be laid in the track before concrete is poured. When placing the extended steel reinforcement sections, the conduits need to be adjusted to prevent interference between them and the reinforcement. Other track-side components may include water pipes, heating elements, gas lines, sensors, etc. For subway construction, many other types of infrastructure may share space with the tunnels used for the subway tracks.

[0029] In stark contrast, the technical solution disclosed herein features a reinforcing steel assembly entirely contained within the block itself. Therefore, the block has no reinforcing steel extensions that could potentially interfere with other track components (such as conduits, other reinforcing bars, other supports, sensors, etc.). Even in the case of temporary additions to the track infrastructure, the technical solution disclosed herein completely avoids any interference with the track infrastructure based on the reinforcing steel. Therefore, designers are free to add components to the track without worrying about interfering with the reinforcing steel extensions (because the technical solution disclosed herein lacks reinforcing steel extensions).

[0030] Reinforcing bar extensions are not the only way to secure blocks in place to avoid stress. The shape of the blocks can be configured to allow the poured concrete to hold them more firmly in place. However, existing shapes for directly securing blocks are suboptimal.

[0031] Existing direct-fixing blocks are typically configured in a rectangular shape, with the block surface perpendicular to the base layer and / or rail fasteners. However, rectangular shapes can be prone to chipping at the corners. For example, installers might accidentally bump into a corner, causing it to break.

[0032] In stark contrast, the technical solution disclosed herein has a substantially circular perimeter at the base. Therefore, installers are less likely to damage the blocks before and / or during installation. An additional benefit is a reduced risk of injury to installers, as the block assembly has fewer sharp edges.

[0033] Regarding the shape of existing block assemblies, the existing rectangular directly fixed blocks are insufficient to resist vertical forces. When the blocks are pulled by the rails, because the periphery of the blocks is aligned with the direction of the force, the blocks can simply slide upwards and out of the poured concrete.

[0034] In stark contrast, the technical solution of this disclosure includes a configuration in which the back surface area is smaller than the ventral surface area. In other words, the technical solution of this disclosure has a more trapezoidal shape than existing rectangular blocks. Therefore, the base (with a larger ventral surface area) is larger than the top (with a smaller back surface area), thus the technical solution of this disclosure is held within the cast concrete. Furthermore, the non-coplanar surfaces of the technical solution of this disclosure firmly hold the block assembly within the cast concrete slab / substrate, with the block assembly acting strongly against the cast concrete slab / substrate. Therefore, the technical solution of this disclosure is more difficult to displace by forces (especially vertical forces / tensions).

[0035] Another problem with existing directly fixed blocks is the risk of rotational forces causing the blocks to move within the poured concrete. Many existing solutions have smooth peripheral surfaces. Therefore, when forces cause the block to rotate, the block's surface merely slides within the poured concrete, leading to displacement. In extreme cases, the block may damage the poured concrete slab / substrate under rotational forces.

[0036] In stark contrast, the technical solution disclosed herein features multiple grooves disposed on the peripheral surface of the block. These grooves cause the block to remain in the installed position because the poured concrete and the grooves abut against each other. The grooves are particularly well-suited to resist rotational forces. Thus, the integrity of the poured concrete slab / substrate is maintained.

[0037] Regarding internal steel reinforcement assemblies, existing direct-fixing blocks include under-optimized steel reinforcement assemblies. Steel reinforcement assemblies are designed to increase the overall integrity of the blocks. However, many steel reinforcement assemblies are configured with an excessive number of bends and / or welds. Therefore, these assemblies may be prone to failure. Furthermore, these steel reinforcement assemblies are more difficult to manufacture, thus incurring additional costs.

[0038] In contrast, the technical solution disclosed herein includes steel reinforcement assemblies configured with an optimized number of bends and / or welds. Therefore, the technical solution disclosed herein possesses a high level of integrity while not incurring excessive manufacturing costs.

[0039] Figure 1A is a perspective view of the fixed assembly 101 from a top view. Multiple axes are shown: a first axis 103X, a second axis 103Y, and a third axis 103Z. Axis 103X is perpendicular to the direction of travel of the locomotive and rolling stock along the rail 102. Axis 103Y is parallel to the direction of travel of the locomotive and rolling stock along the rail 102. Axis 103Z is vertical and is formed by the normal vectors of axes 103X and 103Y.

[0040] The fixing assembly 101 includes a fastener assembly 201 and a block assembly 301. The rail 102 is fastened to the block assembly 301 via the fastener assembly 201. The fastener assembly 201 includes a fastener base 205, a plurality of clamping members 206Z, a plurality of bolts 203Z, and a plurality of locking washers 204Z. The fastener base 205 is generally configured to align and support the rail 102, such that the plurality of clamping members 206Z can fasten the rail 102. The plurality of clamping members 206Z includes a first clamping member 206A and a second clamping member 206B, each of which can be positioned to contact the base of the rail 102.

[0041] The plurality of bolts 203Z includes a first bolt 203AA, a second bolt 203AB, a third bolt 203BA, and a fourth bolt 203BB. The plurality of bolts 203Z are typically configured to operatively connect the fastener base 205 to the block assembly 301. The plurality of bolts 203Z are operatively connected to a plurality of locking washers 204Z, which prevent the plurality of bolts 203Z from loosening. The plurality of locking washers 204Z includes a first locking washer 204AA, a second locking washer 204AB, a third locking washer 204BA, and a fourth locking washer 204BB.

[0042] Those skilled in the art will understand that the bell shape of the block assembly 301 provides stability when it is placed on a concrete slab. Specifically, more surface area (at the ventral surface of the block assembly 301) is in contact with the slab. Similarly, more mass is set closer to this surface, i.e., at the slab. Those skilled in the art will note that the rear surface area of ​​the block assembly 301 is smaller than the ventral surface area.

[0043] The block assembly 301 includes a plurality of recesses 308Z. The plurality of recesses 308Z includes a first recess 308A and a second recess 308B. The plurality of recesses 308Z are generally configured to engage with the poured concrete to further hold the block assembly 301 in place. Furthermore, the plurality of recesses 308Z provide keying engagement into the poured concrete to facilitate mechanical locking with surrounding materials. The bell-shaped shape of the block assembly 301 provides resistance to pulling the block assembly 301 out of the poured concrete. The plurality of recesses 308Z limit the block assembly 301 to vertical forces and provide its stability against rotational forces that cause the block assembly 301 to lift and / or rotate within the poured concrete (which is generally undesirable). Additionally, the plurality of recesses 308Z provide more surface area for adhesion to the poured concrete.

[0044] Those skilled in the art will understand that, due to the relationship between the two assemblies 201 and 301, the block assembly 301 and the fastener assembly 201 can be sold as a kit. For example, a railway operator or installer may expect faster railway deployment and require the two assemblies 201 and 301 to be pre-installed with each other. Therefore, the operator / installer can simply remove assemblies 201 and 301 from the kit and place the assembled assembly onto a concrete slab. Those skilled in the art will understand that fine-tuning may be required, such as checking torque values ​​and adjusting rail clamp components. However, the combined kit offers the advantage of rapid railway deployment.

The plurality of holes 209Z includes a first hole 209AA, a second hole 209AB, a third hole 209BA, and a fourth hole 209BB. The plurality of holes 209Z are generally configured such that a plurality of bolts 203Z can be inserted into fasteners (not shown) via a plurality of cast-in threads within the block assembly 301 to operably connect the fastener assembly 201 to the block assembly 301.

The current view shows an alternative embodiment of the technical solution of this disclosure (i.e., the block assembly 302) in which the plurality of cast threaded fasteners 315Z include fewer cast threaded fasteners and are therefore labeled as a plurality of cast threaded fasteners 316Z. As shown, the cast threaded fasteners 316AA and 316BB are positioned at the same locations as shown in Figures 2A to 2F above, relative to the cast threaded fasteners 315AA and 315BB. Furthermore, the cast threaded fasteners 315AB and 315BA have been omitted relative to Figures 2A to 2F above.

[0063] Block assembly 302 is configured to accommodate an alternative fastener assembly including two holes. For example, the alternative fastener assembly will have a first hole and a second hole. Referring to fastener assembly 201, the first hole will be similar to hole 209AA, and the second hole will be similar to hole 209BB. In addition, holes 209AB and 209BA will be omitted.

[0064] For clarity, fastener assembly 201 can be used with an alternative embodiment shown in this view as block assembly 302. However, holes 209AB, 209BA will not have locking washers 204AB, 204BA and bolts 203AB, 203BA installed. Therefore, the shown alternative embodiment has the advantage of being more aesthetically pleasing while accommodating rail fastener assemblies with two or four holes.

[0065] Figure 4B is a perspective view of the block assembly 302 from a top view. The reinforcing bar assembly 401 is shown in more detail. Figure 4C is a perspective view of the block assembly 302 from a bottom view. The reinforcing bar assembly 401 is shown in more detail again. Figure 4D is a plan view of the block assembly 302 from a top view. The reinforcing bar assembly 401 is shown in more detail again. Figure 4E is a plan view of the block assembly 302 from a bottom view. Finally, the reinforcing bar assembly 401 is shown in more detail.

[0066] Figure 5A is a perspective view of the block assembly 301 from a top view. As described herein, the block assembly 301 includes a back surface 329 smaller than the ventral surface 333 (not shown in this view). The back surface 329 includes a plurality of back surfaces 326Z and a back surface 331. The plurality of back surfaces 330Z includes a first back surface 330A and a second back surface 330B. The plurality of back surfaces 330Z are curved at the periphery 341A of the block assembly 301. The back surface 331 is straight at the periphery of the block assembly 301. To highlight that the back surface 329 is smaller than the ventral surface 333, a plurality of distances 326Z are shown. The plurality of distances 326Z includes a first distance 326A and a second distance 326B.

[0067] Figure 5B is a perspective view of the block assembly 301 from a bottom view. This view shows the ventral surface 333 in full detail. As with Figure 5A above, the dorsal surface 329 is smaller than the ventral surface 333. Similarly, distance 326A highlights this relationship between the dorsal surface 329 and the ventral surface 333.

[0068] As shown in the figure, the ventral surface 333 includes multiple ventral surfaces 334Z and ventral surfaces 335. The multiple ventral surfaces 334Z include a first ventral surface 334A and a second ventral surface 334B. The multiple ventral surfaces 334Z are curved at the periphery 341B of the block assembly 301.

[0069] Unlike the back surface 331, the ventral surface 335 is not continuous at the periphery 341B of the block assembly 301. Multiple grooves 308Z are shown intersecting the ventral surface 335, as indicated by multiple distances 311Z. As described herein, the multiple grooves 308Z provide more stable positioning within the poured concrete without the need for reinforcement extensions.

[0070] Figure 5C is a plan view of the block assembly 301 from a top perspective. The current view shows a plurality of recessed surfaces 307Z extending from the back surface 331 to the front surface 335. Those skilled in the art will understand that the back surface 329 has no recesses, allowing the fastener base 205 (at the front surface) to be mounted on the block assembly 301 with sufficient support. This advantage allows any standard rail fastener to be attached to the block assembly 301 without problems of interference or insufficient support caused by the multiple recesses 308Z.

[0071] Figure 5D is a plan view of the block assembly 301 from a frontal perspective. Figure 5E is a plan view of the block assembly 301 from a side perspective.

[0072] Figure 5F is a plan view of the block assembly 301 from a bottom perspective. The current view shows more clearly the multiple grooves 308Z that cut into the perimeter 341B of the block assembly at multiple distances 311Z. One advantage of the block assembly 301 is that the multiple grooves 308Z gradually taper from the back surface 329 to the ventral surface 333, increasing the surface area of ​​the ventral surface 333. Therefore, the block assembly 301 can be adequately supported on the concrete slab before concrete pouring. This support at the ventral surface 333 enables stability to be maintained during installation and operation.
