Abstract

The rail comprises a profile rail (4) set in the ground. A support (6) is attached via bolts (5) whose heads (7) engage the rail. The support carries the rail extrusion (2) on its top end. The profile rail has an open topped, undercut cross section, preferably forming a C-shape, with the bolt heads then being hammer shaped. The support is preferably has a foot plate (8) through which the bolts pass, attaching it to two parallel profile rails.

Description

The invention relates to a track elevation for running individually above a floor level Rail tracks of a track in railway depots, with in Floor recessed rails and standing on it Screw fixed supports, which one at the top Wear the track.

Such a track elevation is known from EP 0 522 449 B1 known.

Here, the profile rail is from a flat edge strip formed, which is embedded in the ground and on which the Supports are fastened with their footplates by screws, in which these screws in the threaded holes of the profile rail intervention.

The profile rail is included at certain points prefabricated threaded holes, or after the The profile rail must be fixed in the floor Tapped holes are created at certain points, which is relatively unfavorable.

Furthermore, a simple, quick and cost-saving retrofitting of the track system for Adaptation to different train types may be possible. Therefor must then be in place for the other stand of the supports Threaded holes are created in the profile rail what is also labor intensive and expensive, and secondly  in the choice of seats has a restrictive effect, since only new ones Tapped holes can be created where previously none were.

In this known rail-screw connection So always work on the profile rail before Set in the floor or after installation in the floor before Place required, which is disadvantageous on the assembly affects.

The object of the invention is based on this state of the Technology an improved track elevation with a Profile rail screw connection to create what a simple, inexpensive, quick and safe anchoring of the Supports at every profile rail point and retrofitting (Change of location) without working on the profile rail enables.

This object is achieved in that the rails have an open, undercut cross-section and the supports through with their heads into the rails engaging screws are anchored on the profile rails.

Advantageous embodiments of the invention are in the rest Subclaims included.

The supports are screwed directly according to the invention fixed on the mounting rails without the mounting rails Have or must have threaded holes because for the Column fixing profile rails with undercut Cross sections are used, in which the screws with their Heads are inserted and then by screwed nuts hold the supports with the foot plates on the profile rails.  

So there is a choice of location and continuous conversion of the supports on the rails, without special Work and precautions on the rails are required.

The supports are attached directly to the base plate Profile rails placed and then through the in the Cross section of the profile rails with their heads inserted Screws, preferably hammer head screws, by nuts fixed.

This results in simple, quick and safe installation and a cost-effective version for track mounting.

Furthermore, the invention enables an additional one Vertical alignment of the supports through in the foot plates screwable and against the profile rails or the floor acting adjusting screws and after aligning Introducing a casting compound under the base plate Secure the aligned support.

Should be a level floor above the column attachment are desired, then this can be done around the supports Apply a screed to the floor during the conversion can be easily removed.

In the drawings is an embodiment of the invention shown, which is explained in more detail below. It shows:

Fig. 5 is a plan view of the support with a footplate fixed on two profile rails and set screws and a rail track shown in dash-dotted lines.

The track elevation for two rail tracks ( 2 ) of a track running individually above a floor level ( 1 ) has profiled rails ( 4 ) embedded in the floor ( 3 ) and supports ( 6 ) fixed thereon by screws ( 5 ), each of which has a rail track at the top ( 2 ) wear.

The profile rails (4) have an upwardly open, undercut cross-section and the supports (6) are anchored by engaging with its head (7) in the profile rails (4) bolts (5) on the rails (4).

The profile rails ( 4 ) preferably have a C-shaped cross section and the screws ( 5 ) are formed by hammer head screws.

Each support ( 6 ) is fixed to a footplate ( 8 ) by several, preferably four screws ( 5 ) on two parallel profile rails ( 4 ).

As shown in Figures 3 and 4 clearly be seen, the profile rail (4). In cross-section on both sides of its cross-section opening slot (4 a) inward tooth-like molded C-arm (4 b), behind which the hammer head (7) with angled head ends ( 7 a) form-fitting and secured against rotation.

Each support ( 6 ) can be set up in the vertical position by a plurality of adjusting screws ( 9 ) screwed into the base plate ( 8 ) and non-positively acting on the floor ( 3 ) or the base ( 4 c) of the profile rail ( 4 ).

In Fig. 1, only one rail track ( 2 ) is drawn, which is supported by several supports ( 6 ) arranged one behind the other in the longitudinal direction of the track at a distance and fixed on the two profile rails ( 4 ).

Each track has two rail tracks ( 2 ) which are mounted on the assigned supports ( 6 ) without cross-connections, so that the track results in a so-called "open track" and between the rail tracks ( 2 ) there is free access to the underside of what has been driven onto the track Railway carriage is available for repair, maintenance and expansion work.

The two profile rails ( 4 ) for each rail track ( 2 ) are fixed in the concrete floor ( 3 ) with anchors ( 10 ) and reinforcements ( 11 ).

Then the hammer head screws ( 5 ) are inserted into the profile rails ( 4 ) from above by inserting the width of their head ( 7 ) into the slot ( 4 a) ( Fig. 4) and then rotating them by 90 °, so that the head ( 7 ) with its length lies transversely to the longitudinal direction of the profile rail in the C cross section ( FIG. 3).

Now the support ( 6 ) with the holes ( 8 a) of its base plate ( 8 ) is placed over the screws ( 5 ) protruding upwards from the profile rails ( 4 ) and screwed onto the screws ( 5 ) nuts ( 12 ), but still not tightened. The set screws ( 9 ) screwed into the footplate ( 8 ) now align the support ( 6 ) vertically by screwing them against the bottom ( 4 c) of the profile rails ( 4 ) - Fig. 2 and 3 - or directly on the Concrete floor ( 3 ) - Fig. 1 - or act on a counter plate; With this alignment, a gap is created between the concrete floor ( 3 ) and the base plate ( 8 ), which is then filled by a casting compound ( 13 ). Once the casting compound ( 13 ) has hardened, the set screws ( 9 ) are loosened and / or unscrewed and the nut ( 12 ) is then tightened on the screws ( 5 ) so that the aligned support ( 6 ) with its base plate ( 8 ) is fixed stands on the casting compound ( 13 ).

A screed ( 14 ) can be applied to the concrete floor ( 3 ) to create a level floor level ( 1 ).

The undercut cross-section of the profile rail ( 4 ) as a support mounting rail can also be formed from a slotted round or oval tube cross-section in versions not shown, in which the screws ( 5 ) with their tube cross-section matched and corresponding in width to the slot width Head ( 7 ) inserted and turned by 90 ° for anchoring.
