DE102005027751A1 - Interchangeable attachment of the track plates of a magnetic levitation train on a guideway carrier - Google Patents

Abstract

The exchangeable fixing for the movement plate of a maglev track uses anchor screws (3) guided in tubes (4a,b) and engaging in the cement of the track bed (2) and-or movement path plate. The tubes can be compressed in their longitudinal direction by the anchor screws. Each tube can have at least two telescopic sections. claims include a bearing construction and tube for the track.

Description

Technical area

The Invention relates to the attachment of the track plate on the guideway carrier a Maglev.

Anchor bolts, which fix the track plate of the maglev train over bearings on the track girder, be after adjustment of the track plates with mortar in the guideway beams shed. The bearings and track plates are therefore difficult interchangeable.

Object of the invention

task The invention is about the anchor bolts on the guideway carrier fastened Fahrwegplatten and thus the bearings interchangeable to attach and at the same time passed on the anchor bolts occurring forces better to divert into the concrete.

Presentation of the invention

The The object is specified by that in the characterizing part of claim 1 Characteristics solved. For this the anchor bolts run inside the guideway carrier and / or the track plate in tube sleeves (preferably filled with grease), in the longitudinal direction are configured compressible parallel to the anchor screw. Prefers this is done by making at least two nested ones, mutually displaceable parts exist (like a telescope). alternative can the tube sleeves but also be accordion-like designed.

Would that be Anchor bolts in non-compressible sleeves out, so would when tightening the Anchor bolts acting compressing forces only on the wall of the Transfer sleeves and led there to tensions, but they would not derived in the concrete. In the worst case, the sleeve would give way and would something uncontrollably upset, which is caused by the sudden sideways directed forces could easily lead to spalling of the concrete.

Becomes while an anchor bolt in a compressible according to the invention Sleeve attracted, so can the tube sleeve dodge the compressive force without damage and slightly shorten. Because of being over plate-like surfaces (Anchor plates) at the ends of the tube sleeve a compressive force on the concrete lying between the anchor plates. In order to behaves The concrete between the two anchor plates is similar in its strength to its strength Prestressed concrete. He behaves much less brittle. This, in turn, prevents spalling of concrete next to the tube sleeves, which means an increased one Strength of the concrete and thus the driveway of the maglev train leads. But this also gives you the opportunity the dimensions of the anchorage and the route with otherwise the same concrete quality cheaper interpret.

The 1 shows an example of the attachment of a track plate on the guideway carrier by means of anchor bolts, which are guided in compressible tube sleeves. In the example, the tube sleeves are made in two parts and telescopically slidable.

The Track plate lies with the lower anchor plate of the track plate tube sleeve over a steel bearing (ie not elastically mounted) on the upper anchor plate of the Fahrwegträgerrohrhülse. The upper anchor plate of the track plate tube sleeve is in the concrete of the track plate concreted.

The Traverse pathway tube sleeve the edge region of the guideway carrier. Its lower anchor plate is abutment for the nut of the anchor bolt. The anchor plates are preferably made of stainless steel.

Around the telescoping of the tube sleeves to facilitate is located at the end of the outer sleeve around the inner sleeve a bead / ring of compressible material. Without this bead / ring would be at Telescoping concrete at the end of the outer tube sleeve, or the end of the tube sleeve itself, destroyed.

(In the Trap of a concertina-like structure of the compressible tube sleeve would be this accordion-like Part preferably of a thin layer surrounded by compressible material to avoid damage.) The steel bearing between track plate and guideway carrier preferably has a PTFE coating and is also preferably also corrosion resistant in stainless steel executed.

In the example shown, the anchor plates of the track plate tube sleeve and the track tube sleeve have a projecting projection which fits into a recess in the steel bearing and depending on the fit to a fixation of the steel bearing with zero (ie no degree of freedom) or one-dimensional mobility to the anchor plate and thus from track plate to drive leads away.
