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.

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 provided 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, tighten and loosen the set screws to adjust and align the position of the top plate. 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.

According to the invention, the annular gap between the sleeve and pipe or pile is filled with a potting compound in the aligned state. To fill the annular gap is in the above the set screws aligned state of the remote from the top plate portion of the annular gap with a sealing compound against the pipe or the post sealed. As potting compound, a metal polymer is preferably used which contains ceramic and stainless Metallfullstorikombinationen 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 according to the invention, the top plate is provided with at least one inlet bore above the annular gap for the potting compound.

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

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, but releasably connect 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 further embodiment, a cantilever arm is provided, which is connected at one end via bolts to the head 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 21. 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. According to the invention, 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 via at least one inlet bore above the annular gap. 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. 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.
