Description

  The present invention relates to a vehicle track support method using vertical sleepers (hereinafter, including ladder sleepers) and a track position support used therefor, and more specifically, a railroad using vertical sleepers. For a vehicle using a vertical sleeper for receiving a horizontal train load applied to the track and suppressing horizontal movement in the rail length direction and the direction orthogonal thereto in the vehicle track The present invention relates to a track support method and a track position support used therefor.

  Conventional railroad tracks generally have sleepers placed horizontally, that is, at predetermined intervals in a direction perpendicular to the rails, and the rails are arranged in the length direction by embedding both ends of each sleeper in concrete. And horizontal movement in a direction perpendicular thereto is suppressed. Since the concrete construction in this deterrent part must be performed in a narrow environment where jigs for maintaining the position and spacing of the rails are congested, it is difficult.

  In the case of a track with this horizontal sleeper, construction is difficult, and since the structure supports the rail intermittently, there is a drawback that the track tends to be out of order. Then, ladder type sleepers using vertical sleepers have been developed and widely used (Patent Document 1: Japanese Patent Laid-Open No. 9-268504).

  A ladder track using this ladder type sleeper is a ladder-shaped ladder type sleeper (vertical type sleeper) consisting of a pair of left and right vertical beams and a plurality of horizontal beams connecting the left and right vertical beams at regular intervals. It is configured by connecting one after another. In the case of this ladder type sleeper, unlike the case of horizontal sleepers, the vertical load is continuously supported, and the vehicle load is not applied to a specific location, so that the trajectory is less likely to occur. It has the advantage of low noise and vibration.

  The ladder track using the ladder type sleeper includes a ballast / ladder track using ballast and a floating ladder track using a ladder type sleeper laid on a concrete roadbed without using ballast. Floating ladder tracks are mainly used on structures that are unlikely to sink over time, such as viaducts and subways, and are often used with anti-vibration materials that are supported using anti-vibration materials.

  This anti-vibration type floating ladder track has, for example, an L-shaped concrete pedestal consisting of a horizontal part and a vertical wall on a concrete roadbed, and extends in the length direction of the rail with the vertical wall as the outside. The anti-vibration materials made of rubber or polyurethane are arranged at predetermined intervals on the horizontal portion, and ladder type sleepers are laid on the anti-vibration material. In this case, the vertical beam of the ladder type sleeper is in a state of being floated by the thickness of the vibration isolating material from the concrete base between the vibration isolating materials.

  The ladder type sleeper receives a force from the rail in the length direction and a direction perpendicular to the length direction, and the force in the rail orthogonal direction is received by the vertical wall of the concrete base. In other words, in the ladder type sleeper, the position of the concrete pedestal is regulated by the vertical wall of the concrete pedestal. In that case, the cushioning material is arranged at predetermined intervals between the vertical wall and the side surface of the vertical beam.

  In addition, in the vibration-proof material type floating ladder track, each vertical beam is used to prevent the movement of the ladder type sleeper in the length direction of the rail, in other words, to regulate the position in the length direction of the rail. And a notch for engaging the protrusion is formed on the vertical wall of the concrete base. The protrusion is housed in the notch through the cushioning material.

  In the vibration isolator type floating ladder track having such a configuration, it is necessary to continuously provide a concrete base on the concrete roadbed along the rail extending direction. However, the work is carried out by building concrete at the site and driving in concrete, and because of the need to maintain strength, it is necessary to arrange the reinforcing bars densely, and the work load is large and the construction period is prolonged. There was a problem of increased costs. In order to solve such a problem, a vehicle track using a ladder sleeper described in Patent Document 2 (Japanese Patent Application No. 2005-2781) has been proposed.

  A track for a vehicle in which a ladder-type sleeper having a pair of left and right vertical beams that support a rail on its upper surface and a horizontal beam that connects the vertical beams is laid on a concrete roadbed, and is a metal sleeper restrictor Is fixed to the concrete roadbed, and the ladder type sleeper is regulated in position at a predetermined position by the sleeper regulating tool.

  However, the metal sleeper position restricting tool used in this proposal has a metal rib-like protrusion 17 and a small protrusion 20 that are embedded in the concrete base 400a of the concrete roadbed 400 on the lower surface thereof. There is a problem that not only the weight is increased but also the rib-shaped protrusions 17 and the small protrusions 20 hinder the height adjustment when determining the rail surface position. For example, when the rail height is limited, such as when installed on a concrete structure such as an existing viaduct, the metal protrusion on the lower surface of the regulator may be in the way.

  Furthermore, in the case of the metal sleeper restrictor used in this proposal, there are three kinds of restrictors that support the rail perpendicular direction and the vertical direction, a restrictor that supports only the vertical direction, and a restrictor that supports the rail direction. They are prepared and used according to the position of use. As described above, in the case of a method of preparing several kinds of restricting tools and using them properly, not only the material cost is increased, but also it takes time to use them properly, and there is a problem of misuse.

JP-A-9-268504 JP-A-2005-2781

  When changing from a railcar track with a ballast structure to a ladder-type sleeper track, the work is performed in a narrow environment where the jigs for maintaining the position and spacing of the vertical beams are congested and at night. The construction is inevitably difficult and dangerous, so we want to avoid carrying heavy objects as much as possible. However, in the case of the above-mentioned metal sleeper restricting tool, the weight is increased because of the protrusion on the lower surface, so that this request cannot be met. In addition, the metal sleeper regulators described above have a major problem that hinders the height adjustment when determining the rail surface position. There is a problem of fear.

  The present invention was made to solve all of the various problems of the above-mentioned metal sleeper regulator, and it is possible to reduce the weight by reducing the weight with a simpler configuration and reducing the number of types. It is possible to provide a track position support device that eliminates the labor for selective use and the like and has no restriction on the rail height, and by using this track position support device, it is possible to make a ladder from a track for a railcar with a ballast structure. It is an object of the present invention to provide a method for supporting a vehicle track using a vertical sleeper, which can reduce the work burden of changing to a type sleeper track and shorten the work period.

  The invention according to claim 1 for solving the above-mentioned problem is a method of supporting a vehicle track using a vertical sleeper by using a plurality of track position support tools having a single structure, and as the track position support tool. Using at least one of a fixed plate fixed on a support base disposed between the concrete roadbed and the vertical sleeper, and a support plate vertically rising from one end of the fixed plate, The support plate of the support is brought into contact with the outer side surface and / or the inner side surface of the vertical sleeper to suppress movement in a direction perpendicular to the length direction of the rail, and the support plate is moved to the vertical sleeper. A vertical sleeper characterized in that movement in the length direction of the rail is suppressed by abutting a protrusion projecting on the outer side surface and / or inner side surface of each rail in the length direction of the rail. Vehicle using It is the orbit of the support method.

  In a preferred embodiment, a cushioning material is interposed between the support plate and the support plate contact portion of the vertical sleeper.

  According to a third aspect of the present invention for solving the above-described problem, a fixing plate fixed on a support base disposed at least between a concrete roadbed and the vertical sleeper, and a vertical direction from one end of the fixing plate. A track position support device for supporting a vehicle track using a vertical sleeper comprising a support plate that rises on the support plate, wherein the support plate abuts on an outer surface and / or an inner surface of the vertical sleeper. This suppresses the movement in the direction perpendicular to the length direction of the rail and makes contact with each side surface in the length direction of the rail of the protrusion protruding from the outer surface and / or inner surface of the vertical sleeper. Accordingly, the track position supporter is capable of suppressing movement of the rail in the length direction.

  In a preferred embodiment, a reinforcing rib formed from the fixed plate to the support plate is provided. A plurality of the reinforcing ribs are provided, and the lower side includes those located on both sides of the fixing plate and those located in the middle part, of which the middle part is disposed in the middle part or in even rows. The reinforcing rib is formed so that the length of the lower side is shorter than the length of the lower side of the reinforcing rib arranged on both sides.

  Moreover, in preferable embodiment, the recessed part which accommodates a shock absorbing material is formed in the said vertical sleeper contact surface of the said support plate. Furthermore, a bolt hole for inserting a bolt for fixing on the support base is formed in the fixing plate, and the bolt hole is a long hole such as an oval shape.

  The present invention is as described above, and the track position support device according to the present invention is reduced in weight with a simple configuration, and can be used at different locations of vertical sleepers with a single configuration. In addition, since there is no protrusion as in the conventional sleeper control tool, there is an effect that it can be used without being restricted by the rail height.

  In addition, the vehicle track support method according to the present invention uses a single-position track position support with the above-mentioned weight suppressed, so that the material cost can be reduced, and the transportation of heavy objects, etc. Time and effort is reduced. Therefore, difficult work that is performed at night in a narrow environment where jigs for maintaining the position and spacing of the rail are congested, such as changing from a railcar track with a ballast structure to a ladder-type sleeper track, It is possible to carry out quickly without any danger as in the prior art, and in particular, since the track position supporter having a single structure and having no protrusion is used, the height adjustment when determining the rail surface position is possible. It has the effect of being easy and free from misuse.

It is a top view which shows a part of track for vehicles which enforced the method concerning the present invention. FIG. 2 is an enlarged cross-sectional view taken along line AA in FIG. It is (A) top view, (B) front view, and (C) side view which show the structure of the track position support tool which concerns on this invention. It is a figure which shows the usage example (2nd usage) of the track | orbit position support tool which concerns on this invention ((A) shows an outer track use condition, (B) shows an inner track use condition).

  A mode for carrying out the present invention will be described with reference to the accompanying drawings. FIG. 1 is a plan view of a part of a vehicle track using a vertical sleeper in which a method according to the present invention is performed, and FIG. 2 is an enlarged cross-sectional view taken along line AA in FIG. In the illustrated example, the vertical sleeper is an elastic direct connection ladder sleeper composed of a connecting member 62 that connects the vertical beam 61 and the left and right vertical beams 61. The rail 63 is laid on the vertical beam 61 by a conventional method.

  Reference numeral 1 in the figure denotes a track position support according to the present invention. The track position support tool 1 rises vertically from a fixed plate 2 fixed on a support base (adjustment concrete) 71 disposed between at least the concrete roadbed 70 and the longitudinal beam 61 and one end of the fixed plate 2. It consists of a support plate 3 (see FIG. 3). The height of the support plate 3 in the vertical direction is maximized at the upper surface position of the vertical beam 61 and is about 3/4 of the height of the vertical beam 61.

  Typically, the triangular reinforcing ribs 4, 4 a extend from the fixing plate 2 to the support plate 3 in a plurality of rows (typically 3 or 5 rows), for example, the lower sides thereof extend along both side edges and the middle portion of the fixing plate 2. Arranged. At that time, the reinforcing ribs 4a arranged in the middle part (or even-numbered rows) are formed so that the length of the lower side is shorter than the length of the lower side of the reinforcing ribs 4 arranged on both side edges. The

  In the present invention, the fixing plate 2 is bolted onto the support base 71 using bolts. Similarly, the support plate 3 is also attached to the side surface of the vertical beam 61 or the side surface of the projection 64 with a plastic bolt or the like. It shall be bolted or attached using other metal fittings. Therefore, for example, four bolt holes 5 are formed in the fixing plate 2 and the support plate 3 (the bolt holes 5 are shown only on the fixing plate 2 in the attached drawings). The reason why the reinforcing ribs 4a arranged at the intermediate portion are formed short as described above is to prevent them from getting in the way during these bolting operations.

  In particular, the bolt hole 5 formed in the fixing plate 2 is preferably a long hole such as an oval type. By doing so, it is possible to easily cope with the displacement of the structure supporting the track due to the parallel translation in the horizontal direction. The reason why the track position support tool 1 is fixed with bolts is to facilitate the case where a parallel movement or a mistake occurs in the structure supporting the track. If there is a concern about the reduction of the tightening force when bolted, a means such as attaching a locking stopper to the bolt may be devised, or a locking prevention nut may be used.

  Since a displacement that sinks in the vertical direction is assumed to occur in the structure that supports the track, a shim (not shown) is inserted under the track position support tool 1 as a countermeasure. Further, since the support plate 3 of the track position support tool 1 comes into contact with the inner and outer surfaces of the vertical sleepers (vertical beams 61), the contact surface is made of polyurethane, rubber or the like for buffering. The cushioning material 11 is provided (usually the cushioning material 11 is previously installed on the side of the longitudinal beam 61 when it is manufactured). Therefore, in order to hold the cushioning material 11 in a stable and stable state, a recessed portion 6 for fitting the cushioning material 11 is formed on the vertical sleeper contact surface of the support plate 3.

  The vehicle track support method according to the present invention is implemented using the track position support tool 1 having the above-described configuration. In the case of the conventional metal regulator described above, there are three types, a regulator that supports the direction perpendicular to the rail and the vertical direction, a regulator that supports only the vertical direction, and a regulator that supports the rail direction. It was. However, since the track position support tool 1 used in this method is only one of the above-described structures, there is no need to rework the work due to erroneous selection or misplacement, and it is necessary to check whether or not the work is properly placed. Absent.

  As one function (first usage) of the track position support tool 1, the support plate 3 is used only on the outer surface of the vertical beam 61 (usually only the outer surface, but it may be used on the inner surface or both inner and outer surfaces). The vertical beam 61 is restrained from moving in the direction orthogonal to the length direction of the rail 63. Further, as another function (second usage), the length of the rail of the projecting portion 64 protruding from the outer surface of the vertical beam 61 by rotating the support plate 3 by 90 degrees with respect to the first usage. By making it contact | abut to each side surface (front and back both sides | surfaces) of a length direction, the movement to the length direction of the rail 63 of the vertical beam 61 is suppressed.

  The construction method according to this method will be described in more detail. First, a support base (adjusted concrete) 71 that is appropriately extended in the rail direction is provided at a predetermined position on the concrete roadbed 70. Then, a ladder type sleeper composed of a longitudinal beam 61 on which a rail 63 is installed and a connecting member 62 is arranged thereon. Next, the plurality of track position support tools 1 are arranged so that the support plate 3 faces the outer surface of the vertical beam 61 on the outer track side (or inner track side) of each rail 63.

  And after interposing the buffer material 11 between the outer surface of the vertical beam 61 and the support plate 3, the bolt is inserted into the insert embedded in the outer surface of the vertical beam 61 through the bolt hole 5 of the support plate 3. Each track position support 1 is bolted to the longitudinal beam 61 by screwing. The track position support 1 may be bolted to the vertical beam 61 in this way in advance, or may be bolted on site.

  Next, the bolts are screwed into the inserts embedded in the support base 71 through the bolt holes 5 of the fixing plate 2, and the fixing plate 2 is bolted to the support base 71. Secure to. At that time, height adjusting concrete is driven in to adjust the height of the rail 63 as necessary. Thus, the vertical beam 61 is pressed by the plurality of track position supports 1 on the side surface orthogonal to the rail direction, and is restrained from moving in that direction (the first usage).

  Further, the track position support tool 1 is rotated 90 degrees from the direction in the first usage, and the support plate 3 is provided on each side surface in the length direction of the rail of the protrusion 64 protruding from the outer surface of the vertical beam 61 ( It is placed facing both front and rear sides. And after interposing the buffer material 11 between the outer surface of the vertical beam 61 and the support plate 3, the bolt is screwed into the insert embedded in the protrusion 64 through the bolt hole 5 of the support plate 3. Each track position support 1 is bolted to the protrusion 64. The track position support 1 may be previously bolted to the protrusion 64 in this way, or may be bolted on site.

  Next, the bolts are screwed into the inserts embedded in the support base 71 through the bolt holes 5 of the fixing plate 2, and the fixing plate 2 is bolted to the support base 71. Secure to. Thus, the projecting portion 64 is held by the track position support tool 1 on both side surfaces orthogonal to the rail direction, so that the movement of the longitudinal beam 61 in the length direction of the rail 63 is suppressed (the second usage described above). ).

  The bolt screwing insert is temporarily attached to the track position support tool 1 with a bolt for fixing it, and the vertical beam 61 and the like are installed at a predetermined position, and the support base (adjusting concrete) 71 and the concrete roadbed It is good also as making it embed | buy in the support stand 71 when performing 70 construction.

  As described above, in the method according to the present invention, the track position support 1 is bolted to the side surface of the vertical beam (vertical sleeper) 61 and the predetermined position of the protrusion 64, and the vertical position of the rail 63 is adjusted. After that, if the longitudinal beam 61 is arranged at a predetermined position on the concrete roadbed 70 and a rectangular support base (adjusted concrete) 71 partially arranged on the concrete roadbed 70 is constructed, the laying of the vehicle track is completed. To do. As a result, transportation / installation of heavy objects is omitted, danger is avoided, material costs are reduced, construction period is shortened, and construction costs are reduced. Further, since the track position support tool 1 is firmly fixed with bolts or nuts, it is possible to easily and reliably cope with the horizontal or vertical displacement generated in the vehicle track after the start of use. It becomes possible.

  Although the present invention has been described in some detail with respect to its most preferred embodiments, it will be apparent that a wide variety of different embodiments can be constructed without departing from the spirit and scope of the invention, the invention being defined by the appended claims. It is not restricted to the specific embodiment other than limiting in.
