Abstract
Description
Die Erfindung betrifft eine vorgefertigte Stahlbetonfertigteilplatte zur Erstellung einer Plattenverbundkonstruktion gemäss dem Oberbegriff des Anspruchs 1 sowie ein Verfahren zu deren Herstellung.The invention relates to a prefabricated precast reinforced concrete slab to create a Panel construction according to the preamble of Claim 1 and a method for their Production.
Es sind Verfahren bekannt, zur Herstellung einer sogenannten festen Fahrbahn für den Hochgeschwindigkeitsschienenverkehr diese mit Ortbeton herzustellen. Es ist jedoch auch ein Verfahren unter Verwendung von vorgefertigten Stahlbetonfertigteilplatten bekannt, die an ihrer Stossstelle mit den einbetonierten Stahlstäben über das sogenannte Thermit-Schweissen verbunden werden (DE 26 21 793). Hierbei wird zunächst in Teilbereichen der Stossfuge zwischen den Stirnseiten der Stahlbetonfertigteile Beton eingebracht. Danach wird die Schalung für das Thermit-Schweissen in der Stossfuge angebracht und dann mit dem Schweissen begonnen. Hierbei werden die Enden der Stahlstäbe bis ca. 3000 °C erwärmt. Beim Abkühlen ziehen sich die Stahlstäbe zusammen und verpressen hierbei den schon in Teilbereichen eingebrachten Beton in der Stossfuge - zwischen den Stirnseiten zweier benachbarter Stahlbetonfertigteilplatten. Nach dem Abkühlen wird die restliche noch offene Stossfuge nach Entfernen der Schalungsteile für das Thermit-Schweissen ebenfalls mit Beton verschlossen. Methods are known for producing a so-called fixed carriageway for high-speed rail traffic this with in-situ concrete manufacture. However, it is also a procedure using pre-made Reinforced precast slabs known to their Butt joint with the steel rods concreted in the so-called thermite welding can be connected (DE 26 21 793). Here, first in Partial areas of the butt joint between the end faces of the reinforced concrete precast concrete. After that the formwork for thermite welding in the Butt joint attached and then with welding began. Here, the ends of the steel bars are up heated to approx. 3000 ° C. When cooling, they pull Steel rods together and already crimp them concrete in the butt joint in some areas - between the faces of two neighboring ones Precast concrete panels. After cooling the remaining butt joint after removal of the formwork parts for thermite welding also closed with concrete.
Diese bekannte Konstruktion mit dem Thermit-Schweissverfahren hat sich in der Praxis im wesentlichen bewährt. Von Nachteil ist, dass keine definierten Spannkräfte beim Abkühlen der mittels Thermit-Schweissen verbundenen Stahlstäbe und damit auch keine dauerhafte Verbindung des nach dem Thermit-Schweissen eingebrachten Betons mit den beiden Stirnseiten der beiden einander benachbarten Stahlbetonfertigteilplatten erzielt werden kann.This well-known construction with the thermite welding process has changed in practice essentially proven. The disadvantage is that none are defined Clamping forces when cooling the medium Thermit welding connected steel rods and with it also no permanent connection of the after Thermit welding of the concrete introduced with the both faces of the two adjacent to each other Precast reinforced concrete slabs can be achieved.
Der Erfindung liegt die Aufgabe zu Grunde, eine gattungsgemässe Stahlbetonfertigteilplatte zur Erstellung einer Plattenkonstruktion sowie ein Verfahren zu deren Herstellung so weiterzubilden, dass Spannkräfte bei der Herstellung der Plattenverbundkonstruktion definierter einstellbar und dauerhafte Verbindungen des insgesamt zwischen den Stirnseiten eingebrachten Betons erzielbar sind.The invention is based on the object, a generic Precast reinforced concrete slab for Creation of a plate construction as well as a To further develop processes for their production, that resilience in producing the Composite panel construction adjustable and permanent connections of the total between the concrete placed in the front can be achieved.
Diese Aufgabe wird bei einer gattungsgemässen Stahlbetonfertigteilplatte gemäss dem Oberbegriff des Hauptanspruchs erfindungsgemäss durch dessen kennzeichnende Merkmale sowie durch die Verfahrensschritte des Herstellungshauptanspruchs gelöst.This task is carried out with a generic precast reinforced concrete slab according to the preamble of Main claim according to the invention by its characterizing Characteristics as well as through the procedural steps of the main manufacturing claim solved.
Erfindungsgemäss werden also Stahlbetonfertigteilplatten mit zumindest zwei sich in Längsrichtung der Stahlbetonfertigteilplatte erstreckenden und über deren beide Stirnseiten vorstehenden Stahlstäben verwendet, um eine Plattenverbundkonstruktion durch Verbindung der Enden der Stahlstäbe zweier benachbarter Stahlbetonfertigteilplatten zu erzielen. Die Plattenverbundkonstruktion dient hierbei zur Herstellung der sogenannten festen Fahrbahn, insbesondere für den Hochgeschwindigkeitsschienenverkehr, wobei auf der Oberseite der Stahlbetonfertigteilplatten Vorrichtungen zur Anbringung von sich in Längsrichtung erstreckenden Schienen vorgesehen sind. Es können aber auch drei oder mehr Stahlstäbe Einsatz finden, die vorzugsweise symmetrisch bezüglich der Längsmittelebene der Stahlbetonfertigteilplatte angebracht sein können, im Übrigen natürlich an identischer Stelle, da ansonsten natürlich das Verbinden der stumpf aneinander stossenden Enden der Stahlstäbe nicht möglich wäre. Nachdem eine Stahlbetonfertigteilplatte zunächst -bezüglich Richtung und Fugenabstand an einer schon verlegten Stahlbetonplatte angeordnet wird, wird die Stahlbetonplatte in ihrer Höhe und Ausrichtung justiert und in dieser Lage die stumpf aneinander stossenden Enden der Stahlstäbe kraftschlüssig, vorzugsweise durch eine Schweissverbindung über eine Winkelschiene miteinander verbunden. Die Fertigteilplatten sind im seitlich äusseren Bereich jeder Stirnseite der Stahlbetonfertigteilplatte mit einem Absatz versehen, der ein parallel zur Stirnseite verlaufendes Widerlager aufweist, dessen Flächennormale parallel zur Längsrichtung der Stahlbetonfertigteilplatte verläuft. Diese an beiden äusseren Seiten im Bereich der Stirnseite angebrachten Absätze werden verwendet, um eine vorzugsweise hydraulisch betätigbare Presse dort einzusetzen und im Sinne des Auseinanderdrückens zu betätigen, wobei die Stahlstäbe gespannt werden. In dieser gespannten Stellung wird in den Bereich der Stossfuge zwischen den beiden Stirnseiten der Stahlbetonfertigteilplatte eine sich verfestigende Füllmasse, vorzugsweise Beton eingefüllt und danach die beiden in den Absatz eingesetzten hydraulischen Pressen entspannt, wobei sich infolgedessen die vorgespannten Stahlstäbe entspannen und dabei zusammenziehen und hierbei die gesamte Füllmasse in der Stossfuge zwischen den Stirnseiten verpressen. Hierbei wird infolge der erfindungsgemässen Verankerung jedes Stahlstabes an nur einer Stelle in der Stahlbetonfertigteilplatte und deren im Übrigen frei dehnbare Anordnung der Vorteil erzielt, dass eine konstante Dehnstrecke nämlich stets in der Länge jeder Betonfertigteilplatte bereitgestellt und infolgedessen eine grosse Spannkraft auf den in der Stossfuge eingebrachten Beton ausgeübt werden kann.According to the invention, precast reinforced concrete slabs with at least two in the longitudinal direction of the Reinforced precast slab extending and over whose two end faces use protruding steel bars, around a composite panel construction by connection the ends of the steel bars of two neighboring ones To achieve precast reinforced concrete slabs. The composite panel construction serves to manufacture the so-called solid road, especially for the High-speed rail traffic, being on the Top of the precast reinforced concrete slabs Devices for attaching themselves in Longitudinally extending rails are provided. However, three or more steel rods can also be used find that are preferably symmetrical with respect to the Longitudinal median plane of the precast reinforced concrete slab may be appropriate, of course identical place, otherwise of course that Connect the butt ends of the Steel bars would not be possible. After one Reinforced precast slab initially Direction and joint spacing on an already installed one Reinforced concrete slab is arranged, the Reinforced concrete slab in its height and orientation adjusted and in this position the butt against each other butting ends of the steel rods, preferably by a welded connection via a Angle rail connected together. The Precast panels are in the outer side area with each face of the precast reinforced concrete slab provided with a paragraph parallel to End face extending abutment, the Surface normal parallel to the longitudinal direction of the Precast reinforced concrete slab runs. This on both outer sides in the area of the face attached paragraphs are used to create a preferably hydraulically operated press there use and in the sense of pushing apart press, tensioning the steel rods. In this tense position is in the range of Butt joint between the two faces of the Precast reinforced concrete slab is a solidifying Filling compound, preferably filled in concrete and then the two hydraulic used in the paragraph Presses relaxes, and consequently the pre-stressed steel rods relax while doing so contract and thereby the entire filling mass in the butt joint between the end faces. This is due to the inventive Anchoring each steel rod in only one place the precast reinforced concrete slab and the rest thereof freely stretchable arrangement the advantage achieved that a constant stretch always in length provided every precast concrete slab and consequently a great resilience to the in the concrete brought into the butt joint can.
Mit der erfindungsgemässen Stahlbetonfertigteilplatte bzw. dem Verfahren zur Herstellung einer Plattenverbundkonstruktion wird der Vorteil erzielt, dass einerseits einstellbare und definierte Kräfte in den Stahlstäben erzeugt werden können, die dann einerseits die Füllmasse in der Stossfuge zwischen den Stirnseiten benachbarter Stahlbetonfertigteilplatten konstant und definiert und wegen der im Gegensatz zum Stand der Technik grösseren freien Dehnbarkeitslänge der Stahlstäbe mit grösserer Kraft vorgespannt werden können. Infolgedessen ergibt sich eine gute und dauerhafte Verbindung zwischen den Stirnseiten der solchermassen miteinander zu einer Plattenverbundkonstruktion verbundenen einzelnen Stahlbetonfertigteilplatten.With the precast reinforced concrete slab according to the invention or the process for producing a composite panel construction the advantage is achieved that on the one hand, adjustable and defined forces in the Steel bars can then be produced on the one hand, the filling compound in the butt joint between the faces of neighboring precast reinforced concrete slabs constant and defined and because of the im Contrary to the prior art, larger free ones Elongation length of the steel bars with greater force can be biased. As a result a good and lasting connection between the End faces of such a degree together Panel composite construction connected individual Precast concrete panels.
Nach dem Verbinden kann die immer noch mittels Justiermittel justierte Platte mit einer sich verfestigenden Masse, beispielsweise Beton unterfüllt bzw. unterpresst werden, sodass die Justiermittel gelöst werden können. After connecting, you can still use Adjuster adjusted plate with a solidifying Mass, for example concrete underfilled or pressed, so that the adjustment means can be solved.
Um zu verhindern, dass die unterpresste bzw. unterfüllte Masse sich mit der Unterseite der Stahlbetonfertigteilplatte verbindet, kann dort eine Trennschicht vorhanden sein. Somit ist es ebenfalls möglich, auch noch nach Jahren eine Nachjustierung vorzunehmen, ohne hierbei die sich verfestigte Masse zu beschädigen und / oder zu entfernen.To prevent the underpressed or underfilled Mass with the bottom of the precast reinforced concrete slab connects, there can be a separation layer to be available. So it is also possible, readjustment even after years undertake without the solidified mass to damage and / or remove.

Stahlbetonfertigteilplatte. Auf deren Oberseite 11
sind Aufnahmeteile 12 für Schienen und deren
Halterungen vorgesehen. Ausserdem können
Einfüllöffnungen 13 zum Unterfüllen der justierten
Stahlbetonfertigteilplatte 10 verwendet werden.
Ferner sind auf der Oberseite quer, vorzugsweise
senkrecht zur Längserstreckung 14 verlaufende
Einkerbungen 15 vorgesehen, die als Sollbruchstellen
dienen können.Figure 1 shows a plan view of a
according to the invention, generally designated 10
Precast concrete panel. On the
An den beiden Stirnseiten 16, 17 stehen die schematisch
mit 18 bezeichneten Enden der in der Stahlbetonfertigteilplatte
10 vorgesehenen (nicht sichtbaren)
Stahlstäbe vor, die an jeder
Stahlbetonfertigteilplatte 10 an identischer Stelle
und vorzugsweise symmetrisch bezüglich der Längsrichtung
14 vorgesehen sind. Beim wiedergegebenen Ausführungsbeispiel
sind 6 Stahlstäbe vorgesehen.At the two
Jeder dieser Stahlstäbe 19 (Figur 1) ist an einer
Stelle, beispielsweise an der Stelle 20 des (in Figur
1 obersten Stahlstabes 19) unbewegbar verankert. An
den übrigen Stellen ist der Stahlstab 19 frei dehnbar.
Somit ist die Dehnstrecke zwischen zwei Ankerpunkten
20 zweier zugeordneter Stahlstäbe 19 der
benachbarten Stahlbetonplatten 10 stets konstant und
entspricht der Länge der Stahlbetonplatte 10, vorausgesetzt,
der betreffende Stahlstab 19 ist an jeder
Stahlbetonfertigteilplatte 10 an identischer Stelle
verankert.Each of these steel bars 19 (Figure 1) is on one
Location, for example at
Jede der beiden Stirnseiten 16, 17 ist ausserdem mit
einer symmetrischen mittigen sowie zwei äusseren vorspringenden
Stossstellen 21 bzw. 22 versehen, die auf
ihrer freien Oberseite eine Ebene aufweisen, deren
Flächennormale parallel zur Längserstreckung 14 des
Betonfertigteils 10 verläuft. Die mittlere Stossstelle
21 dient hierbei als Querdübel zur Aufnahme von
quer zur Längsrichtung 14 der Stahlbetonfertigteilplatte
10 verlaufenden Belastungen (Figur 2). Ausserdem
kann, wie die schematische Seitenansicht gemäss
Figur 3 im Bereich der Stossfuge 23 zeigt, eine
Tasche 24 vorgesehen sein, die von Einwölbungen der
Stirnseiten 16, 17 gebildet wird. Somit ist auch eine
zusätzliche Sicherung gegen quer zur Längsrichtung
nach oben oder unten auftretende Kräfte geschaffen.
Die schematische Darstellung gemäss Figur 3 ist in
Figur 6 nochmals in grösserem Massstab dargestellt.
Hierbei wird die in Figur 7 näher dargestellte, im
Querschnitt winkelförmige Winkelschiene 25 mit zwei
gleichlangen und rechtwinklig aufeinander stehenden
Schenkeln 26 von unten gegen die Enden 18 jedes
Stahlstabes 19 gelegt und mittels einer Schweissnaht
27 unter Bildung einer kraftschlüssigen Verbindung
zwischen den beiden Enden 18 der stumpf
aneinanderstossenden Stahlstäbe 19 verbunden (Figuren
6 und 7).Each of the two end faces 16, 17 is also with
a symmetrical central one and two outer protruding ones

Ausserdem ist die Betonplatte 10, wie auch Figur 5
zeigt, mit zwei - in Draufsicht - äusseren Absätzen
30 versehen, die ein parallel zur Stirnseite 16, 17
verlaufendes Widerlager 31 aufweisen, wie in Figur 4
gezeigt ist. In diesen Absatz werden, nach Herstellung
der kraftschlüssigen Verbindung 28 (Figuren 5 - 7)
Hydraulikpressen 32 eingesetzt, welche bei
Beaufschlagung derselben mit Hydraulikflüssigkeit mit
einer definierten Kraft die beiden benachbarten
Stahlbetonfertigteilplatten 10 voneinander weg auseinander
drücken sowie in dieser Lage halten, nachdem
zuvor die Platte in Anordnung, Höhe und Erstreckung
ausjustiert worden ist. Danach wird die Stossfuge 23
nicht nur im Bereich der Stossstellen 21, 22, sondern
auch im Bereich der Tasche 24 mittels einer sich verfestigenden
Füllmasse, vorzugsweise Beton, gefüllt,
wonach die mittels der Hydraulikpresse 32 aufgebrachte
Auseinanderdehnkraft gelöst und die Hydraulikpresse
32 entnommen werden kann. Hierdurch bedingt
bewirkt die Kraft der in Folge der Hydraulikpressen
32 vorgespannten Stahlstäbe 19, dass die beiden
Stahlbetonfertigteilplatten wieder im Bereich der
Stossfuge 23 unter Vorspannung der dort befindlichen
Füllmasse - geringfügig - aufeinander zu bewegt
werden. Es ergibt sich infolgedessen eine mit konstanter
und einstellbarer sowie gegenüber dem Stand
der Technik grösserer Kraft vorgespannte sowie mit
Füllmasse gefüllte Stossfuge, die eine dauerhafte
Verbindung darstellt.In addition, the
Weiterhin sind ausserhalb der Stirnseiten 16, 17
jeder Stahlbetonfertigteilplatte auf deren Unterseite
33 zumindest zwei auf je einer Seite bezüglich der
Längsrichtung 14 nach aussen hin offene Justierfugen
34 vorgesehen, die eine parallel zur Unterseite 33
verlaufende Stützfläche 35 aufweist. Ferner weist die
Justierfuge 34 eine durch die Stützfläche 35 bis zur
Oberseite 11 der Stahlbetonfertigteilplatte 10 durchgehende
Bohrung 36 auf, durch die mit einem Aussengewinde
versehener Justierstab 37 hindurchragt, der auf
der Unterseite eine Stützplatte 38 sowie eine
Verstellschräube 39 aufweist, die sich an der Stützfläche
35 abstützt. Ferner ist eine Einfüllöffnung 40
zum Unterfüllen der Stahlbetonfertigteilplatte 10
vorgesehen. Wird eine PE-Rundschnur 41 auf der Unterseite
vorgesehen, so kann über die Einfüllöffnung 40
eine sich verfestigende Masse, beispielsweise Beton
eingefüllt werden. Selbstverständlich ist es auch
möglich, in an sich bekannter Weise die
Stahlbetonfertigteilplatten 10 zu unterpressen. Um zu
verhindern, dass sich die verfestigende Masse mit der
Unterseite 33 der Stahlbetonfertigteilplatte 10
verbindet, kann eine Trennschicht 42 vorgesehen sein.
Ferner ist auf der Unterseite eine sich in
Längsrichtung erstreckende Fuge 43 (Figur 8)
vorgesehen, die bei Unterfüllung mit der Masse zur
Aufnahme von Querkräften der
Stahlbetonfertigteilplatte 10 dient.Furthermore, outside the end faces 16, 17

- Process for manufacturing a composite slab structure, in particular a fixed carriageway for high-speed railway traffic, comprising prefabricated reinforced concrete slabs with at least two inserted steel rods (19), extending in longitudinal direction (14) of the prefabricated reinforced concrete slab (10) and protruding over its two end faces (16, 17), so that the two mutually aligned flush ends (18) of the steel rods (19) of two adjacently arranged reinforced concrete slabs (10) are positively connected and a solidifying filler compound is filled between the two end faces (16, 17) facing each other that solidifies, forming a tight connection between the two prefabricated reinforced concrete slabs (10), characterised such that each steel rod (19) is anchored in such a way that it cannot move at only one point (20) in the reinforced concrete slab (10) and can otherwise stretch freely, that the ends (18) of the steel rods (19) are positively connected together, that consequently the two adjacent reinforced concrete slabs are pushed apart away from each other with defined force of the steel rods (19) and are held in this position, that a solidifying fill compound is then filled into the entire butt joint (23) between the two adjacent end faces (16, 17) of the prefabricated reinforced concrete slabs (10) and that finally the two reinforced concrete slabs (10) held apart with defined force are released under the effects of the resulting restraint of the fill compound.
- Process in accordance with Patent Claim 12, characterised such that threaded rods with ends connected positively by means of a screw socket with opposing internal threads are used as the steel rods.
- Process in accordance with Patent Claim 12, characterised such that the ends (18) of the steel rods (19) are welded together.
- Process in accordance with Patent Claim 14, characterised such that a. steel rail (25) with an angular cross section is used to weld each end (18) of the steel rods (19).
- Process in accordance with one of the Patent Claims 12 to 15, characterised such that concrete is used as the fill compound.
- Process in accordance with one of the Patent Claims 12 to 16, characterised such that the height of the reinforced concrete slab (10) arranged in terms of direction and joint spacing is adjusted and underfilled or underpressed with a solidifying compound.
- Process in accordance with Patent Claim 17, characterised such that concrete is used as the compound.
- Process in accordance with Patent Claim 17 or 18, characterised such that a separating layer (42) that prevents the connection between this layer and the solidifying compound is used to facilitate subsequent adjustment between the hydraulically bound subbase and the underside (33) of the prefabricated reinforced concrete slab (10).
- Process in accordance with Patent Claim 18, characterised such that the compound is applied through filler openings (14) extending through the prefabricated reinforced concrete slab (10) to its underside (33).
