Description

The present invention relates to a device for establishing signal towers for rail traffic. Rail transport needs signals that have a mast height of a few meters. These signals are placed in the area of the track, in which case neither the strength of the track bed may be affected, nor any cable ducts or the like may be damaged next to the track bed.

For the foundation of signal towers, a number of approaches are known. In a first approach, a concrete foundation is placed in a pit to be prepared. The concrete foundation consists of a series of concrete parts, which are stacked to form a tower and connected together. The concrete foot thus formed may have a length of 1,500, 1,800, 2,100 mm. The concrete base consisting of precast concrete parts must be moved on site using a crane or a two-way excavator, whereby the individual parts are usually transported pre-assembled into the installation area. For installation is a pit with a corresponding shoring and, where appropriate to produce a lowering of the groundwater. Since the erection of the signal can take place, inter alia, in the pressure area of the tracks, particularly high requirements for carrying out the work apply here. The built-in concrete base is subsequently cast, in which case anchor bolts are cast on the foundation for connection to the signal foot.

In addition to the use of concrete foundations is known to use Rammpfahlfundamente on which a precast concrete head is placed. The finished part head is placed on the pile and potted with this. The connecting bolts for the signal foot are also cast in here. Potting the header on site extends the installation time as a corresponding cure time is required. Furthermore, a subsequent correction of the altitude as well as a reuse of the head part is excluded after the casting.

From Patent Abstracts of Japan 09032006A and JP 9-32006 an anchorage for a lantern is known. The anchoring has a pipe driven into the soil with a rectangular cross-section. Mounted on the tube is a sleeve with a rectangular cross-section. Each of the four side walls of the sleeve has four mounting holes. The top plate is additionally provided with a central bore. To attach the sleeve, a total of 16 bolts are bolted to the post above the side walls. The top plate is additionally bolted centrally in the axial direction with the post. In order to avoid a gap between the sleeve and pile, lining sheets with appropriate thickness between sleeve and pile are arranged.

From Patent Abstracts of Japan 04073381 and JP 4-73381 a foundation body for a mast is known, in which a pipe is driven into the ground and the tube has at its upper end a peripheral flange which is connected to a mast base.

The present invention has for its object to provide a device for the founding of signal masts, which provides a simple means reliable recording for the signal mast to be built.

The object of the invention is achieved by a device having the features of claim 1. Advantageous embodiments form the subject of the dependent claims.

The inventive device for the foundation of signal masts for rail transport has a Signalfußadapter. The signal mast to be built is mounted with its signal foot on the signal foot adapter. The Signalfußadapter consists of a sleeve and a top plate. The sleeve, which may also be referred to as a jacket tube, has dimensions such that it is intended for connection to a pipe or pile to be introduced into the ground. Preferably, the pipe or pile is rammed into the soil. The top plate is connected to the sleeve and has means that allow the attachment of a signal foot to the top plate. According to the invention, the sleeve has at least one bore along the peripheral wall, through which an adjusting screw can extend into the sleeve. Preferably, at least four holes for adjusting screws are provided along the circumference. The adjusting screws make it possible to align the sleeve with the pipe driven into the ground. Before attaching the signal foot adapter, the position of the head plate can be adjusted and adjusted by tightening and loosening the set screws. For example, the means provided in the top plate for fixing the signal foot can be aligned by a few simple handles relative to the rail. Also, the orientation of the Signalfußadapters without the use of heavier device by a person can already be done very accurately. As a particularly advantageous to the signal foot adapter according to the invention has been found that no longer a pit in the pressure range of the track is required for installation. Furthermore, the installation of Signalfußadapters is possible by hand and the use of large equipment is not essential. Also, the shape and handling of the Signalfußadapters is much easier compared to the previously known solutions.

Preferably, the top plate forms the conclusion for the sleeve. The top plate is placed on the sleeve formed as a jacket tube.

In a preferred embodiment, the sleeve has a length of 350 to 650 mm, preferably a length of 500 mm is used. It has been found that with this length of the sleeve already for a range of application for main, main / Sperr- and Vorsignalen with and without additional indication according to drawings S8000.5.4 and 58000.3.5 of the BZA Munich from January 31, 1985 and for corresponding mechanical signals sufficient stability is achieved. Essentially, the Signalfußadapter with a length of about 500 mm provides sufficient stability for masts of different heights with and without boom and with an arrangement of different points of light. The inner diameter of the sleeve is adapted to the intended Pipe or the pile, such that the sleeve can be set with a small clearance on the pipe or the pile and connected to this.

For connection with the driven into the soil pipe or pile, the sleeve is provided along its circumferential direction with at least one hole for fastening screws. The holes for fastening screws are preferably arranged one above the other in pairs in the axial direction and distributed uniformly over the circumference of the sleeve for better stability.

In a preferred embodiment, the top plate has a central opening, which allows engagement in the interior of the sleeve. The opening may, for example, have a diameter of approximately 200 mm and is arranged centrally on the sleeve. The opening is used in particular to attach fastening screws for the sleeve to the rammed into the ground pipe, for example, by holding a locking nut from the inside against the mounting screw or rotated.

In a preferred embodiment, the top plate is provided with holes for receiving screws, which guided by the holes screws from the top plate for connection to the signal foot protrude.

The through-holes are preferably arranged in the top plate corresponding to receiving bores in the signal foot. Here, the through holes are arranged for example in a square with a side length of 390 mm or 280 mm, in addition, further through holes may be provided for receiving additional screws. The approach, unlike the known devices, no longer firmly insert screws, sondem detachably connected to the top plate, has the advantage that they can be replaced if damaged. Furthermore, they can also be used shortly before assembly. For this purpose, the screws are preferably held for fixing the signal foot on the Signalfußadapter via a self-locking nut in the top plate and are perpendicular from this before.

In an alternative embodiment, are for attachment to the signal foot anchor bolt vertically from the top plate.

The top plate is supported on support node plates preferably laterally on the sleeve.

In a preferred embodiment, the annular gap between the sleeve and pipe or pile is filled with a potting compound in the aligned state. For filling the annular gap, the part of the annular gap remote from the top plate is preferably sealed in the position aligned by the adjusting screws with a sealing compound opposite the tube or the post. As potting compound, a metal polymer is preferably used which contains ceramic and stainless metal filler combinations based on polymers. Such metal and polymer combinations are also referred to as multimetal and produce a frictional connection. For ease of processing of the potting compound, the top plate may be provided with at least one inlet bore above the annular gap for the potting compound.

In a further embodiment, a cantilever arm is provided which is connected at one end via bolts to the top plate of the sleeve and in a spaced-apart area has means for fastening the signal foot of the signal mast. The extension arm can be used in areas where the driven pile due to special Ratios spaced apart from the track bed to be anchored. The extension arm is preferably designed as a double-T profile. The bore for the bolts are provided in the profile legs, wherein in the region of the bore strips between the profile legs are provided to support these.

The object of the invention is also achieved by a method having the features of claim 25. The method according to the invention serves to establish a signal tower for rail traffic. In an initial step, a pipe or pile is inserted into the soil. Subsequently, a sleeve with a peripheral wall and a top plate is placed on the pipe or pile, wherein the inner diameter of the sleeve is larger than the outer diameter of pipe or pile. Dimensions between pipe and pile are chosen so that the top plate can be adjusted at the upper end of the sleeve in an angular range. To align the patch sleeve at least one reaching through the peripheral wall screw is provided, which rests against the outer wall of pipe or post. The attached sleeve can be easily aligned with the adjusting screw. This allows easy handling and stepless alignment of the top plate. In a preferred development of the method, the annular gap between the sleeve and the mast in its end facing away from the top plate is sealed with a sealing compound. Subsequently, the annular gap is filled with a potting compound. The potting compound forms a frictional connection between the sleeve and pile. If the potting compound is very thin, it is expedient to seal the annular gap before potting. If the potting compound is viscous, it can be dispensed with a sealing of the annular gap and subsequently only the leaked potting compound can be removed. The potting compound is preferably a metal polymer.

A particular advantage of the method according to the invention is that the top plate is provided with a layer of a metal polymer and a foot plate of the signal mast is set flat on the top plate. The footplate is secured to the top plate via several bolts that extend through the top and bottom plates. The direct connection of head and foot plate leads to a significant improvement in stability. Compared to other solutions where there is a gap between the head and foot plate can be achieved here on the flat edition a particularly high stability. Any unevenness in the range between 0 and 15 mm can be compensated by the use of the potting compound, in particular the use of the metal polymer.

Preferred embodiments of the invention will be explained in more detail with reference to FIGS.

As already mentioned, the signal foot adapter according to the invention is mounted on a ram tube 14 or a driven pile. This is introduced according to a known installation method in the soil, which can be used to protect the Rammrohrs 14 and Rammhauben. In principle, it is also possible to introduce the tube 14 with another method in the ground. The assembly of the signal foot adapter according to the invention takes place in the following steps:

• Place the signal foot adapter on the ram tube.
• Aligning the signal foot adapter in height and direction with alignment relative to the rail. The orientation of the angular position via the adjusting screws 18th
• Fixing the aligned Signalfußadapters, for example with the screws 18. It is conceivable to provide additional disks or the like for aligning the Signalfußadapters on the ram.
• In a subsequent step, the through holes 22 are introduced into the ram tube 14, while lining plates or the like are inserted for filling the annular gap.
• Subsequently, the Signalfußadapter is fixed with mounting screws 20 on the Rammrohr, the screws are tightened crosswise to the fixed position.
• The anchor bolts 34 on the top plate 12 are attached and tightened. If possible, this step takes place shortly before the signal tower is installed, as this avoids any damage to the anchor bolt.
• The annular gap formed between the sleeve and the ram is subsequently cast with a metal polymer.

As in the prior art, the signal foot adapter according to the invention for the large signal design can be provided with anchor bolts of dimension M24 and a distance of 390 mm. The small tree shape is equipped with bolts of dimension M20 and a corresponding distance of 280 mm.

Figures 8 to 10 show two different configurations for the Signalfußadapter. For a better overview below the same components are provided with the same reference numerals.

The embodiment shown in Fig. 8 clearly shows the annular gap 38 between tube 14 and the sleeve 10. As shown in Figures 8 to 10, the angular position of the sleeve 10 can be adjusted in an angular range of 1.3 °, so as the top plate 12 horizontally align with the bolt 40.

The sleeves shown in Figures 8 and 9 differ in the design of the fastening bolts for the signal foot. The fastening bolts 40 are screwed to the top plate 20 via a lock nut 42. The signal foot (not shown) has a bore through which the bolt 40 extends. A nut pair 44, 46 then secure the signal foot plate. This is a distance between the top plate and the base plate. The load is introduced via the bolt 40 in the top plate.

The embodiment in FIGS. 9 and 10 in contrast has a flat connection between the signal base plate 48 and the top plate 12. A layer of a multimetal steel is provided between the two plates. Such a multimetal steel is a metal polymer with ceramic and stainless filler combinations. After curing, the multimetal steel has a very high compressive strength and chemical resistance with long-term effect. This allows a hundred percent gap compensation in the range of 0 to 10 mm done positively. In contrast to a gluing, the multimetal can be released, for example, for maintenance work with a release agent.

Subsequently, the connection of base plate 48 and head plate 12. The fastening bolts 50 are secured by a nut 52. The multi-metal used in the connection between the top plate and the signal base plate can also be used to fill in the annular gap.

Figures 11 and 12 show a cantilever arm 54 which is connected via a bolt 56 to the top plate 12. The spaced end of the cantilever arm 54 has four projecting bolts 58 which are provided for connection to the signal foot. The bolts 58 shown in Fig. 11 have a pair of lock nuts for clamping the signal foot plate. However, it is also possible to dispense with the locknuts 60 and place the signal footplate directly on the cantilever arm 54 and interconnect via a metal polymer and corresponding bolted connections.

Between the legs of the profile support strips 62 are set, which form an outwardly open chamber for the holes.
