Description
[0001] The present invention concerns first, a procedure for a
precisely aligned erection of a support beam (hereinafter,
"support") structure for a grade level travelway to accommodate a
rail guided vehicle, in particular, a magnetically levitated
railway vehicle, wherein the support possesses a top travelway
plate with thereon attached guides for the said vehicle, this upper
plate resting upon an under-structure, which has a base plate, this
base plate being separated at a distance from the travelway plate
by at least one intervening web. Besides the said erection, the
invention concerns second, a grade level travelway of a track
guided vehicle, especially a magnetic railway vehicle, wherein the
support possesses a top travelway-plate with thereon attached
guides for the said vehicle, this upper plate resting upon an
under-structure which has a base plate, this base plate being
separated at a distance from the travelway plate by at least one
intervening web.
[0002] DE 198 08 622 A1 discloses a generic travelway, which
consists of precast concrete plates, on which are located lateral,
functional planes for the guidance of a rail limited vehicle. The
precast concrete plate is affixed on the top surface of a
support-structure by means of extending members, as well as being
secured in that location by fastening devices. The securement is
executed in such a manner, that a free elongation is enabled for
the of the concrete precast plates due to temperature expansion.
The support structure itself is set down on prepared ground at the
selected location. Also, if it is correctly held, in the case of
this cited invention, that where a grade level travelway is
concerned, the thereto belonging precast top plate, which carries
functional planes, must respond to temperature compensations.
However, to the contrary, experience has indicated, that during
extreme conditions, this alone is not sufficient to meet conditions
of severe demand and does not always assure the position of the
functional planes responding to travel operation. Contrarily, the
building of a travelway from individual construction components,
successively superimposed, one on top of the other, has proven
itself as highly satisfactory. Because of the small, allowable
tolerances in the guidance of a magnetically levitated travel-track
it required that impacts, even at high temperatures, are to be held
within narrow allowable tolerances.
[0003] Thus, the purpose of the present invention is, to create a
grade level travelway and also make available a construction
procedure for said travelway, wherein heat expansions, even at
large temperature variations, are held within allowable
tolerances.
[0004] This purpose is achieved by a procedure and a travelway
having the features of the independent claims.
[0005] In the case of the procedure in accord with present
invention, the support structure is laid upon a base plate with the
intervention of a web or webs situated on the said base plate. In a
direction transverse to the longitudinal axis of the structure, the
support is subjected to directive members (hereafter "guides") on
the base plate, so that in this location, a transverse motion of
the support is largely excluded. By means of self-extending
spindles, on the base plate or the web, the support is caused to
comply with its preselected space-curvature. The intervening
openings, which arise therefrom are subsequently filled with a
grout between the base plate and/or the web, which advantageously
allows a longitudinal displacement of the carrier on the base
plate. Because of this invented procedure, assurance is provided,
that the support will undergo a temperature expansion only in a
very defined manner. While a transverse displacement is
predominately excluded, a longitudinal movement of the support in
this advantageous embodiment is restricted to a path along the
guide element. This enables, that an exact positioned operation of
the support becomes possible even under extreme environmental
conditions, since now, the heat expansions do not act upon the
function of the vehicle. At least in the advantageous embodiment,
the support is force-fixed in position by the said grout with the
under structure. While, in the case of short supports, preparations
for a longitudinal displacement of the support is not necessary,
conversely, where longer supports are involved, then the
recommendation is advantageously directed toward compensation of
the longitudinal extension. Exactly at which length of the support
the tendency for longitudinal extension becomes necessary, depends
on the conditions of the construction site and the requirements of
the allowable tolerances during operating life.
[0006] If the support has a web, then, it is of particular
advantageous, that the connection between the support and the base
plate be in the area of the web. The shaping of the web can serve
as an element for the guidance of the support in a coaction with
the guides on the base plate.
[0007] If the support is essentially continuous in its setting on
the base plate, then, a very simple manner of construction for the
support is possible. Moreover, a particularly exact guidance of the
support is obtained, by means of which tolerances can be held
within a very narrow range.
[0008] The said spindles can be placed on the webs or at the
connections. The arrangement having the greatest advantage depends
upon the shape of the support and the accessibility of the
spindles.
[0009] It is of special advantage, if the support, at least at one
position, especially in the area of the middle of the support, is
immovably affixed to the base plate. In this case, a rigid
connection is made, which can serve as an base from which the
longitudinal heat expansions of the support can extend themselves.
If this fixed position is in the middle zone of the support, then
the support experiences a relatively small heat expansion extending
in both longitudinal directions from the centerpoint of the said
fixed position. The connection positions to the subsequently
following supports are, thereby, little affected by the heat
expansion.
[0010] If, between the guidances and the support, a rigid grout
material is used, then in this case, occurring longitudinal and
transverse forces are diverted through the shape-fit connection
between the guidances and the support, more exactly, the guidances
and the attendant grout material. The support, in this case, is
thereby so closely guided that no, or the very least, of movements
can take place in the transverse direction. In this way, a precise
positioning of the support, that is to say, the attachments of the
upper chord, is possible. The guidance of the vehicle, with this
arrangement, can be carried out very exactly.
[0011] If between the base plate and the support, especially
between the grout and the support, a partition layer is placed,
then a longitudinal displacement of the support can advantageously
take place without a stressful reaction. The support then slides on
the said partition layer during such expansion as may be created by
temperature changes or by applied loadings. This can occur, in
keeping with the invention, without uncontrolled movements or
contingent damages.
[0012] Advantageously, between the said spindle and the base plate,
a plastic layer is inserted, which, when subjected to load, has the
ability to yield. This said layer, in this protective manner,
extends through the entire surface between the support underside
and the thereunder located grout. A discrete diminishment of the
load through the spindle is prevented.
[0013] Advantageously, for the filling of the transverse guide
openings, which were placed at an increased distance from the
fixation and located between the support and the guides of the base
plate, an elastic grout material was used. The elastic grout is
more or less compressed by the allowable longitudinal displacements
of the support. Even in this case, damage to the support or to the
base plate is avoided, and a desirable movement of the support is
made possible.
[0014] In an especially advantageous manner, the attachment
elements placed in the upper chord were secured by being grouted
in. In this case, it has shown itself to be of advantage, if the
pouring of the upper construction parts with the attachment parts
was carried out in one work-step with the manufacture of the upper
chord and this is done overhead. By means of overhead incorporation
of the attachments in concrete, a favorable and exact connection of
the members can be obtained in the upper structure. Alternative to
this, it is possible that the attachment elements can be welded or
screwed to the attachment plate. This is possible, either with
steel construction or with concrete construction and creates
advantages, in the case of individual embodiments of the
invention.
[0015] If the support, in the case of applied load, already has
been under-grouted, then assurance is given, that the support, and
consequently the attachments thereon will hold their required
positions even under the application of loads.
[0016] In order to maintain a stepless continuation of the linearly
following supports, when under the passage of a vehicle, provision
has advantageously been made, that along the travelway, successive
supports may be connected together, if the grout fill is elastic.
If, contrarily, a grout fill is used, which is rigid and thus does
not permit a depression of the support during passage of a vehicle,
then the successive supports must remain uncoupled.
[0017] In accord with the invention, a generic travelway may be
designed in such a manner, that the travelway comprises a support
on the base plate having an intervening web attached to the support
or to the base plate. The support is limited as to movement in the
transverse direction by guides on the base plate and/or on the web.
On this account, a lateral displacement of the support is not
possible.
[0018] Spindles are placed on the support and/or the web for the
positioning of the support in accord with the required space
curvature. The intervening space between the base plate and/or the
web and/or the support is filled by a grout which permits
longitudinal displacement of the support on the base plate. By
means of design of the travelway, incorporating these features, a
exact lateral guidance of the support and the thereon attached
equipment--which attached equipment is important for the guidance
of the vehicle--is assured. The temperature changes, which must
inevitably occur, and the therewith connected longitudinal changes
of the support, by prior considerations, are incorporated in
longitudinal displacement of the said support.
[0019] A transverse displacement of the support and therewith
problems in the travel operation are thus reliably avoided.
[0020] Advantageously, the support is continuously carried on the
base plate. This assures an exact guidance of the said support and
the therewith related guidance of the vehicle.
[0021] If the support possesses a web, which, in the construction
assembly, extends itself downward from the said support, then, the
possibility exists, that an alignment of the support with the base
plate is advantageously realized. Moreover, the support itself
receives, by the presence of a web, an additional stability,
whereby the erection work and the operation are improved.
[0022] If the base plate is a ground plate, on which the support
stands, then in this case, a simple and rapid manufacture is
possible.
[0023] In an advantageous manner, the guides for the support
consist of one or more blocks or intervening troughs. The blocks,
which, for example, act as one with the webs of the support,
provide the support with a guide in the longitudinal direction. The
same occurs, if, in the base plate 1 a trough is furnished, in
which the support can be seated. Even in this case, a known
displacement of the support through shape-fitting is possible.
[0024] If the support possesses a plurality of, or especially two
webs, which are distanced one from the next in a transverse
direction of the support, then an especially stable support has
been created, which is also very easily guided. The blocks of the
base plate, for example, can be placed between the two webs and
thus a simple, shape-fitted longitudinal guidance for the support
has been made available.
[0025] If the webs, at least on that side which is remote from the
upper chord are at least partially bound together, then, once
again, an additional stability is provided for the support. Beyond
this, it is possible, that at this position, the support can be
bound with the base plate, whereby a solid seating is achieved.
This solid seating can be made by a bolting with the base plate, or
the base plate and the support, for example with the use of a
connection reinforcement, can be united by concrete.
[0026] It is particularly favorable, if the support, especially in
its mid section, is affixed to the base plate. This arrangement
makes it possible, that the expansion extension of the support can
move in both directions from the point of this connection, with the
advantage that the individual displacement of the said expansion in
each of the two portions of the support is lessened.
[0027] If between the guidances and support, a rigid grout material
is placed to create a shape fit connection and to lessen the
longitudinal and transverse forces, then, in this case, during the
erection of the support, adjustment can be made possible even in
the transverse direction, and subsequently, during a pour, a rigid
connection can be made, which makes possible a relative movement
between the support and the base plate in the longitudinal
direction of the support.
[0028] It is of particular advantage, if between the base plate and
the support, more exactly, between the under grout and the support,
a partitioning layer intervenes. The partitioning layer assures the
mutual relative displacement of the base plate and the support
means to one another.
[0029] If between the base plate and the spindle a plastic plate is
inserted, which, especially, yields to some extent when loaded,
then a reduction in the amount of grout materials can be achieved.
In operation, a discrete lessening of the load is prevented by
means of the spindle.
[0030] In regard to the under lying grout, the use of mortar or an
elastomer is highly regarded. Mortar creates a rigid substrate for
the support, while by means of an elastomer, an elastic binding can
be achieved. Where the use of an elastomer is concerned, the
support will undergo a type of weight-spring-system which
especially contributes to a smooth run of the vehicle.
[0031] By means of the elastic bedding of the support on the base
plate, the said weight-spring-system can likewise be brought about.
The depressing of two neighboring supports upon the roll-over of a
vehicle must be compensated for by a coupling of the two supports
in order to avoid an impact.
[0032] If, in the transverse members, between the support and the
guide of the base plate, which is further removed from the point of
fixation at a known distance, an elastic material is applied, then
the longitudinal expansion of the support is compensated for by
this given grout material.
[0033] If the attached construction elements in the upper chord are
molded in or welded or screwed onto the said upper chord, then a
firm connection is established between the said attachments and the
upper chord, whereby the positional precision of the attachment,
dependent upon the upper chord (i.e., the upper chord) is made sure
of.
[0034] It is of advantage, if the support and/or the base plate
possesses through running water fittings or run-off openings. Such
construction makes it possible for inspection personnel and also
for animals to cross the travelway and, in the case of rainwater or
snow melt, dammed up water is avoided.
[0035] If the support terminates, at least at one of its ends,
relative to the base of the web or the base plate, this situation
will cause an opening to be formed, which persons or animals can
use for crossing the travel way.
[0036] If the base plate and/or the support is made specially as a
precast concrete component, then a very exact fabrication and
moreover a very rapid field installation of the travelway is made
possible.
[0037] Further advantages of the invention are illustrated and made
manifest in the following embodiment example with the aid of the
drawing. There is shown in:
[0038] FIG. 1 a base plate in a perspective view,
[0039] FIG. 2 a longitudinal section through a support and a base
plate,
[0040] FIG. 3 a detailed view of the end of a support,
[0041] FIG. 4 a detailed view of a support midsection,
[0042] FIG. 5 a perspective section presentation of two supports,
following one another and in
[0043] FIG. 6 to FIG. 9 additional embodiments
[0044] FIG. 1 shows a perspective presentation of a base plate 1,
in accord with one embodiment type of the present invention. The
base plate 1 consists of a ground plate 2, upon which two blocks 3
are located. The ground plate 2 and the blocks 3 are made of
concrete and are laid upon the ground. The ground plate 2 can also
be an otherwise intended construction member, such as, for example,
a bridge or the bottom foundation of a tunnel section.
[0045] The blocks 3 place the guide elements for the support, which
at a later time will be set upon the ground plate 2. For the
execution of the purposes of the guide elements, the blocks 3
possess lateral sides 4, which, under some circumstances, with the
coaction of the of a grout material (to be described later)
injected between the lateral sides 4 and the support, permit a
movement of the support in the longitudinal direction x. The blocks
3 possess in this embodiment example, moreover inner sides 5 and
outer sides 6. These sides 5 and 6, which, in other, not presented
embodiments are not unconditionally necessary, can receive grout
applications in accord with the present embodiment. This grout
application would be in reference to the support. At least the
sides, here 5 and 6, placed more remotely from a solid bearing of
the of the support are advantageously provided with an elastic
grout material, so that heat expansions, which act in the
x-direction of the support can be absorbed by the elasticity of
this material resulting in freedom from damaging or improper
stresses.
[0046] After the base plate 1 is laid along the travelway, then the
actual travelway structure is placed thereupon on the upper surface
7 of the base plate 1.
[0047] The guidance elements in the x-direction of the support, in
accord with another, not shown embodiment example, also can be
formulated in a different manner. For instance, it is possible,
that instead of blocks located midway, also blocks can be provided
which guide the support from the outside. In this case, instead of
provision of blocks being installed midway on the base plate 1,
three blocks could be placed on the outer edge of the base plate 1
and externally guide the support. As an additional alternative,
similar to the externally placed blocks, provision can be made,
that the base plate 1 possesses a trough, in which the support can
be set. The trough, in this case, must be so dimensioned or set in
grout filling, so that a movement of the support in the x-direction
is permissible.
[0048] FIG. 2 shows a perspective presentation of a longitudinal
section through the base plate 1 and a support 10. The support
comprises an upper chord 11 and webs 12 which are connected
thereto. The webs 12, of which in the present presentation,
principally only one is illustrated, are bound on their end, which
is remote from the upper chord 11, by means of the connections 13
and 14. Between the webs 12 and the said connections 13 and 14 are
placed the blocks 3 of the base plate 1. The blocks 3 form in
connection, especially with the webs 12, a longitudinal guide of
the support 10 in the x-direction.
[0049] In the area near the inner connection 14, the support 10 is
securely bound by means of a threaded bolt 15 with the base plate
1. The longitudinal expansion of the support 10 on this account,
then starts from this binding position at the said inner connection
14, and extends simultaneously in directions to each end of the
support in the location of the outer end connections 13.
[0050] To maintain the alignment of the support 10, especially in
the vertical z-direction, spindles 16 are provided. The spindles
16, are to be found in the connections 13 and 14 of embodiment
example of FIG. 2. These spindles 16, after the support 10 has been
lowered on to the surface 7 of the base plate 1, are more or less
screwed out of the support 10 and thus perform the adjustment of
the said support 10 to such a measurement as would be required for
the travelway. After the required position of the support 10, by
means of the spindles 16 has been established, then the intervening
space caused thereby between the support 10 and the surface 7 of
the base plate 1 is filled with a grout 20. This grout must be of
such a nature, that it can compensate for longitudinal
displacements of the support 10 on the surface 7, which can result
from stresses of heat expansion or loadings thereon. In this
respect, an partition layer 25 can be interposed between the
underside of the support 10 and the grout 20, so that an adherency
between the said underside of the support 10 and the grout 20 can
be avoided. The partition layer 25, or other means for the
prevention of a tight binding, can obviously be provided between
the grout 20 and the surface 7 of the base plate 1.
[0051] Between the blocks 3 and the support 10, additional grout
applications 22, 23, 24 can be made. The lateral grout material 22
is advantageously rigid upon cure and likewise is provided with a
separative layer. In this matter, likewise, action can be taken
similar to that of the grout application and the separative layer,
in that a sliding of the support 10 in the x-direction relative to
the base plate 1 can be carried out, without the danger of
over-stress. The lateral grout application act in such a way, that
the support 10, during its longitudinal displacement is exactly
guided and thus no improper movement in the transverse direction y
is made possible.
[0052] FIG. 3 shows a detailing in the area of an outer connection
13. Beneath the outer connection 13, the said rigid grout 20 has
been applied. After the spindles of the support 10, hard grout 20
fills the intervening space between the upper surface 7 and the
underside of the connection 13, i.e., the web 12. The hard grout
material 20 makes a secure connection in the vertical z-direction,
so that the guidance of the traveling vehicle above the support 10
remains predominately unchanged in the z-direction. In accord with
an exact alignment of the support 10, it is possible that a
connection of the support 10 with a previous or a trailing support
can be omitted. This is because, in the z-direction, no essential
movement is to be expected in regard to the over-run of the
vehicle. Alternatively instead of a hard grout, it is possible that
an elastic grout material be used. If this be done, then a kind of
weight-spring-system is brought about, which can make possible a
smooth run of the vehicle. Upon the usage of an elastic grout
material 20, in any case a coupling of the support 10 with the
previous and the following support is necessary, so that, the
vertical movement which arises from the suddenly occurring
displacement caused by the impact of the passage of the vehicle
does not lead to a displacement between the first and a second
support, whereby the travel operation of the vehicle could be
disturbed.
[0053] Since heat expansion of the support 10 in the x-direction is
to be expected, advantageously, between the outer side 6 of the
block 3 and the connection 13, an elastic inner grout application
23 is employed. Accordingly, the heat expansion in the x-direction
is absorbed by the elastic grout 23 material and no opening is
formed, that is, no undesirable stress is exercised between the
outer connection 13 and the blocks 3 or the said elastic grout 23.
As an alternate, it is also possible to completely omit the grout
23, if the formation of the blocks 3 or the connection 13 is of
such a nature, that an intervening space between the block 3 and
the connection 13 is allowable. The essential function of the block
3, namely, to permit the movement of the support 10 in the
x-direction, and conversely to prevent displacement thereof in the
y-direction, is actually carried out by the sides 4 and the web 12,
as well as the intervening grout 22 along with the use of a
separating layer if necessary. The sides 6 and the elastic grout
material 23 have little to do with this function.
[0054] FIG. 4 shows a detail view in the area of the inner
connection 14. The support 10 in this case is rigidly bound with
the base plate 1 by means of a threaded bolt 15, which run through
the inner connection 14. The bolt 15 causes, moreover, the holding
down of the support 10, so that in the case of a run-over by the
vehicle, a motion of the support 10 in the z-direction is avoided.
Between the inner connection 14 and the blocks 3 is placed a rigid
grout 24. By means of this, the secure fix of the support 10 is
activated, which is in addition to above action of the said bolt
15. A relative motion between the base plate 1 and the support 10
in the x-direction is predominately excluded by the inner
connection 14, the blocks 3, and the rigid grout 24. There arises
herewith, a secure binding of the support 10 on the base plate 1.
Shown in doted lines is the grout 20, which is placed between the
surface 7 of the base plate 1 and the support 10. Also shown is the
partition layer 25. In the area of the inner connection 14, this
grout can also be placed underneath the inner connection 14.
Alternatively, it is possible to provide, underneath the connection
14, also the hard grout 24.
[0055] FIG. 5 presents a perspective sectional drawing of two
linearly successive combinations of the said base plate 1 and the
support 10. Between the base plates 1 is made available a joint
piece 30, which is filled with grout. The base pates 1 can be
coupled together in a conventional manner, so that a continuous
underlay for the support 10 exists. The support 10 possesses an
upper chord 11, which, in relation to the web 12 is extended
somewhat longer. The hereby created offsets allow, that penetrative
openings 31 may be made. Through these openings, it is possible for
maintenance personnel as well as animals to cross the travelway.
Beyond this, in this way an opening has been made through which
water can flow.
[0056] On the outer end faces of the upper chord 11 are placed
attachments 32. These attachments 32, which form the functional
surfaces for guidance and driving of the vehicle, are also the
construction components, which must be placed with extraordinary
precision in order to guarantee the running operation of the
vehicle. On this account, it is very important, that at the
abutments between two attachments 32 an offset and a separating
distance will occur which are principally within the allowable
tolerances. This condition is taken care of by the present invented
design of the base plate 1 and support 10.
[0057] FIG. 6 show a further embodiment example of the present
invention. In this case, the base plate 1 possesses a self standing
under construction, for example a bridgelike construction. On this
base plate 1 the support 10 is placed with the attachments 32.
Contrary to the foregoing embodiment examples, the support 10 is
essentially built as a plate. The webs 12 are only indicated. The
attachments 32 are embedded in the concrete of the support 10,
which is contrary to the embodiment of FIG. 5, where the
attachments 32 were bolted into place.
[0058] FIG. 7 shows a support 10 as seen from below in a
perspective view. The presented support 10 is a so-called short
support, which principally possesses two connection 13 between the
webs 12. A connection 14 as seen in the foregoing embodiment
examples, is, in this embodiment, totally lacking. In the
connection 13 are to be seen the spindles 16. As to the rest, the
fastening of the support 10 on the base plate 1 complies with the
previous descriptions.
[0059] In FIG. 8 is presented a support 10 on a base plate 1. The
spindles 16 are fastened within the webs 12. Between the webs 12
and the base plate 1 the corresponding intervening space is filled
with the grout 20. The intervening space between the webs 12 is
sealed with concrete. The thereby created connection 28 creates,
especially, with an corresponding connection with the base plate 1,
a guidance for the support 10 in its transverse direction. If a
relative movement between the connection 28 and the support 10 is
not desired, then the possibility exists, as is here shown, of
providing reinforcements 29, which ties the support 10 to the
connection 28. The connection 28 and the grout 20 can be made from
the same material, and if desired, made simultaneously.
[0060] In FIG. 9 is shown a support 10 with only one web 12. The
support 10 is placed on the base plate 1 and is guided by means of
external, laterally placed elevation means. The intervening space
between the elevations and the remainder of the base plate 1 is
once again filled with a grout material 20. The adjustment of the
support 10 on the base plate 1 is done by means of the spindles 16.
The guide attachments for the vehicle are the same as in the case
of the other embodiment examples and located, as before on the
upper chord 11 of support 10. While the fastening in the case of
some of the examples is done by incorporation in the concrete, in
this case the fastening is based on a console on the upper chord
11.
[0061] The present invention is not limited to the presented
embodiment examples. Thus, the arrangement of a web on the support
10 can be entirely omitted. A base plate can also consist of a
bridge or another primary construction piece. For this purpose, an
embodiment such as is presented in FIG. 6 is not required. The
blocks 3 can first, be made of concrete, after the support 10 has
been placed on the base plate 1. The blocks 3 can consist of the
same material as the grout 20 and be bound with the base plate 1 by
means of a connection structure.
