Definitions
- the invention relates to a method and an apparatus for producing semi-open concrete parts according to the preamble of claim 1.
- Such a method and a device suitable for this purpose is, for example, with the subject of WO 01/87565 A1 described.
- a fiber concrete is used, which is designed as liquid concrete.
- a formwork body is used, which is installed in a formwork. It is therefore a molding box, in which pressure is applied via pressure and force on the first formwork part in the direction of a second formwork part and so after the introduction of the fiber concrete in the formwork body, the excess water can be pressed on the fiber concrete.
- the molding box thus described had a movable inner box which was pressed against the fiber concrete mass filled on the inner wall of the outer box to displace the excess water of the fiber concrete and finally to bring it towards the outside of the molding box.
- a disadvantage of this known method is that the mold box is inflexible and not readily adaptable to various semi-open concrete parts, that it is difficult to produce, because the pressure elements and the pressure-generating, necessary for the squeezing of the water machine elements are difficult to manufacture and in the cited document are not designated in detail.
- An equal filling over a filler neck is, for example, in the DE 198 41 047 C1 disclosed. There is poured for a tunnel lining concrete via a filler neck of a tubule formwork closed on all sides with the escape of air and water from the tubbing formwork in the tubbing formwork. After reaching a green state strength is turned off.
- the invention is therefore the object of developing a method and apparatus for producing semi-open concrete parts of the type mentioned so that a much better quality of the concrete part is achieved and a simpler process flow is given.
- the invention is characterized by the technical teaching of claim 1.
- An essential feature of the invention is that now according to the invention no self-contained form is used, but a semi-open mold, which forms a large upwardly open Einhellraum, on the large surface of the concrete (liquid concrete) can flow and that after completion of the top half open Form with a top opening the final pressing element, a pressure is exerted from above on the filled concrete mass, so as to squeeze the excess water in all directions out of the mold.
- a pressing element is used so as to close the mold space upwards and to compress the concrete poured there against the arranged in the mold space filter plates and squeeze out the water.
- liquid concrete is understood to mean that it is a conventional flowable concrete, which in a known manner consists of aggregates, cement and water, wherein a high proportion of water is present.
- the liquid concrete has a slump of about 70 to 80 cm and is therefore very fluid.
- the liquid concrete can be added in a conventional manner and fibrous materials, so as to achieve a fiber concrete, which shows a high breaking strength on the cured part.
- This is a significant advantage over known other manufacturing processes that use a so-called polymer concrete, which consists essentially of a sand-resin mixture, which mixture is cured by an increase in temperature and formed after manufacture such as glass and of course upon exposure to Shocks also breaks.
- the invention is not limited to the use of a carrier form of a metal sheet.
- Plastic molds, wood forms and the like may also be used to transfer the surface structure of the carrier mold to the precast concrete element.
- the molding box essentially consists of a peripheral frame which has a slotted bottom and at least one carrier mold is inserted into this molding box so as to fill the carrier form with concrete from the bottom (foot side) to the top ,
- the device feature that the walls of the molding box are designed to be displaceable in order to enable demolding of the finished precast concrete finished.
- the displaceable walls are formed by pressure plates, which pressure plates are in turn provided with pressure elements, which pressure elements are connected to tappets, so that they are designed to be movable in the horizontal direction.
- each wall of the molding box can be moved away from the completed precast concrete part and delivered to allow proper demolding.
- filter plates are arranged on the inside of the printing elements, which are preferably formed from steel plates.
- the filter plates preferably have a perforation or slit of z. B. 30 microns, in order to achieve that only the water escapes with the introduction of pressure from the top press and not the embedded grain in the cement.
- one is relatively free in the shaping of the side walls and can also introduce various projections, recesses and other elements on the side walls, because this only requires a change on the pressure-applying side of the respective pressure plate.
- end plates are also formed as printing plates and protrusions or recesses protruding into the mold space can also be arranged at these locations.
- both beads and undercuts on the inside of the precast concrete part on the design of the carrier form can be introduced by the inventive method as well as the outside on the design of the longitudinal side and the front side adjacent pressure plates.
- the molding boxes provided according to the invention with the features described above in a ring-shaped process sequence, so that a clocked method is used which uses a plurality of molding boxes according to the invention.
- a station 2 is charged, in which the casing of the mold box takes place with a carrier mold 40.
- the thus completed molding box with the carrier form used is in the direction of arrow 4 (see also FIG. 3 ) via a longitudinal conveyor 5, which is preferably designed as a chain conveyor, a station 6, in which the filling of the mortar is carried out in the upwardly open shape of the molding box 22.
- the FIG. 1 shows here a mortar pump 7, via which the substantially pressureless filling of the liquid concrete (concrete 39) takes place in the upwardly open filling chamber 52 of the molding box 22.
- a lifting conveyor 10 is arranged on the inlet side, which lifts the filled molding box 22 from the longitudinal conveyor 8 and brings it into the pressing space of the top press 53. This takes place in the area of the station 11.
- the pressed shape thus prepared is again deposited via a lifting conveyor 10 on a longitudinal conveyor 12 and fed in the direction of arrow to a station 13, where the stripping of the molding box 22 takes place.
- both the arranged on the longitudinal side and on the front side boundaries of the mold box are moved away from the finished mold so as to demould the mold can.
- the finished form is a converter 15 in a storage station 14 according to FIG. 2a spent.
- the now deflated form is spent on a longitudinal conveyor 17 in the arrow direction in a station 18, in which the molding box can be replaced either or a new molding box can be used or the molding box coming from the station 13 is simply forwarded.
- the onward transport takes place via a longitudinal conveyor 19 in the arrow direction FIG. 3 in a washing station 20 where the entire mold is washed.
- a complete circuit is shown and in a preferred embodiment, a molding box are each arranged at each station 2, 6, 11, 13, 18, 20, so that all molding boxes are cyclically conveyed on the circulation system 1 clocked from station to station.
- FIG. 4 shows a preferred embodiment of a molding box 22, as arranged according to the above description in each case at the stations.
- the molding box 22 consists of a self-contained, approximately rectangular frame 23, wherein the frame 23 consists of mutually parallel and a mutual distance to each other engaging longitudinal beams 24, 25, to which the transverse bars 26, 27 are arranged vertically.
- all the bars 24-27 are in the horizontal direction (with respect to the plane to FIG. 4 ) arranged movable and are therefore deliverable and weg tone provided so as to ensure a defined filling 52.
- a respective pressure element 28, 29 is arranged, which respectively push the associated wall into the mold space or withdraw from the mold space.
- the side walls of the receiving space 30 are formed by pressure plates 37, on which externally abut pressure pieces 34, which in turn are bolted to a pressure plate 33, which is part of a plunger 32, preferably pneumatically or hydraulically or electromechanically in the direction of arrow 57th is designed to be removable and removable.
- a slide plate 44 is arranged, which is displaceably driven on a raceway 46 in the arrow directions 45.
- a locking of the respective plunger 32 in the advanced position (positive engagement after FIG. 5 or 6 ) to counteract the significant internal pressure of the mold. It is therefore a locking of the feed movement of the plunger 32 in the direction of arrow 57 to the left according to FIG. 5 , and in this case the slide plate 44 is slidably held on a bearing block 43, which bearing block is fixed on the bottom 31 of the mold plate 22.
- FIG. 5 and 6 Now show that in the area of the molding box 22 in the receiving space 30, the pressure elements 28, 29 protrude, thus defining a fillable shape, as in FIG. 5 and 6 is shown.

- FIG. 5 shows that in the production of different height and differently shaped channel elements readily possible, now the ram 32 with the pressure elements 28, 29 apart, so as to form a different sized mold space in the molding box, in which then the carrier mold 40 is inserted , which is filled in the direction of arrow 42 from above practically without pressure with concrete 39.
- the concrete thus flows according to FIG. 6 on the top of the carrier mold 40 and distributed evenly throughout the mold including filling the foot space 59, in which the base leg of the channel-shaped element is formed. It is clear that here a particularly uniform filling of the entire mold space is given, because the liquid concrete evenly distributed under the action of gravity in the mold and this when pressing the mold from above with the press die 54 shown later (see FIG. 9 ) the excess water in the direction of arrow 54 against the inside of the pressure plates 37 spaced filter plates 36 is pressed. There, only the water is squeezed out and reaches a drainage chamber 48 arranged beyond the filter plates 36 and flows downwards in the direction of the arrow 50 out of the mold.
- the mold top namely in the area of the pressure plates 37, are closed at the top by a cover cover 38, which is part of the press ram 54 and which has a filter, so that the excess water can also flow out of this area to the outside ,
- Figures 5 and 6 shows, moreover, that in the production of different channel elements to compensate for a height offset (see the channel element after FIG. 5 and the gutter element FIG. 6 ) can arrange a spacer plate 35 below the mold box 22 in order to always allow a constant comparison of the printing elements 28, 29.
- the base plate 41 of the flask 22 is bolted to the spacer plate 35 or directly on the floor 31.
- FIGS. 7 and 8th show modifications of the mold box according to the invention, where it can be seen that it is also possible in an embodiment of a molding box, several printing elements 28a, 28b superimposed to use a highest possible channel element 56 according to FIG. 7 manufacture.
- the molding boxes 22a, 22b, 22c are thus modified according to the requirements of the semi-finished precast concrete element produced therewith.
- a pressure of about 1 to 2 N per mm 2 is used up, which press ram 54 in the arrow directions 58 on the top of the molding box 22 and is weg constructive.
- any recesses and chamfers can also be connected in the leg region of the base legs of the concrete plate parts produced in this way.
- FIGS. 10 and 11 the cross section is shown by a channel member 56 at different points of this channel element.

Abstract
Description
Gegenstand der Erfindung ist ein Verfahren und eine Vorrichtung zur Herstellung von halboffenen Betonteilen nach dem Oberbegriff des Patentanspruches 1.The invention relates to a method and an apparatus for producing semi-open concrete parts according to the preamble of claim 1.
Ein derartiges Verfahren und eine dazu geeignete Vorrichtung ist beispielsweise mit dem Gegenstand der
Der damit beschriebene Formkasten hatte einen beweglichen Innenkasten, der gegen die an die Innenwand des Außenkastens eingefüllte Faserbetonmasse gepresst wurde, um das überschüssige Wasser des Faserbetons zu verdrängen und zum Abschluss in Richtung auf die Außenseite des Formkastens zu bringen.The molding box thus described had a movable inner box which was pressed against the fiber concrete mass filled on the inner wall of the outer box to displace the excess water of the fiber concrete and finally to bring it towards the outside of the molding box.
Nachteilig bei diesem bekannten Verfahren ist allerdings, dass der Formkasten unflexibel ist und nicht auf verschiedene halboffene Betonteile ohne Weiteres anpassbar ist, dass er schwer herzustellen ist, weil die Druckelemente und die druckerzeugenden, für das Auspressen des Wassers notwendigen Maschinenelemente nur schwer herzustellen sind und in der genannten Druckschrift auch nicht im Einzelnen bezeichnet sind.A disadvantage of this known method, however, is that the mold box is inflexible and not readily adaptable to various semi-open concrete parts, that it is difficult to produce, because the pressure elements and the pressure-generating, necessary for the squeezing of the water machine elements are difficult to manufacture and in the cited document are not designated in detail.
Auf alle fünf Platten des Formkastens musste ein entsprechender Druck ausgeübt werden, was mit einem hohen Maschinenaufwand verbunden ist, der zu hohen Herstellungskosten des Formkastens führt. Außerdem ist der Formkasten anfällig gegen Beschädigungen und nur schwer handhabbar.On all five plates of the molding box, a corresponding pressure had to be exerted, which is associated with a high machine complexity, which leads to high production costs of the mold box. In addition, the mold box is prone to damage and difficult to handle.
Nachdem die Innenwände des inneren Formkastens gegen die Außenwände des äußeren Formkastens verschoben werden müssen, gibt es komplizierte Verschiebebahnen, die außerdem noch dicht gegen Eindringen von Faserbeton sein müssen.After the inner walls of the inner mold box must be moved against the outer walls of the outer mold box, there are complicated displacement tracks, which must also be still tight against penetration of fiber concrete.
Insbesondere in Kantenbereichen ergaben sich somit Schwierigkeiten beim Übergang, und die Kantenbereiche mussten noch mit zusätzlichen Dichtelementen abgedichtet werden.Difficulties in the transition thus resulted, in particular, in edge regions, and the edge regions still had to be sealed with additional sealing elements.
Insgesamt war es mit dem genannten Verfahren und der Vorrichtung nur schwer möglich, halboffene Betonfertigteile herzustellen, die den Anforderungen an die spätere Oberflächengenauigkeit, die Oberflächengüte und der Bruchfestigkeit genügten.Overall, it was difficult to produce semi-finished precast concrete parts with the said method and apparatus, which met the requirements for the subsequent surface accuracy, the surface quality and the breaking strength.
Nachteilig war ferner, dass die Wände des Formkastens nicht veränderbar waren, d. h. es waren keine die Wandabstände verändernden Pressstößel oder dergleichen vorhanden, so dass bei einer gleichbleibenden dünnen Wandstärke von z. B. 2 cm oder weniger es schwierig war, ringsumlaufend mit guter Qualität den Flüssigbeton (Faserbeton) einzupumpen.Another disadvantage was that the walls of the molding box were not changeable, d. H. There were no wall spacers changing press ram or the like available, so that at a constant thin wall thickness of z. B. 2 cm or less, it was difficult to pump round around with good quality the liquid concrete (fiber concrete).
Auch diese Schwierigkeiten beeinträchtigten die Fertigungsqualität der damit hergestellten halboffenen Betonteile.These difficulties also affected the manufacturing quality of the semi-open concrete parts produced therewith.
Eine gleiche Einfüllung über einen Füllstutzen ist beispielsweise auch in der
Nachteil bei der Verwendung einer derartigen Tübbing-Schalform ist wiederum die Tatsache, dass bei einer feststehenden Wandstärke der Beton über eine Mörtelpumpe eingefüllt werden muss, was aufgrund der verwendeten relativ dünnen Einfüllstutzen mit großen Schwierigkeiten verbunden ist.Disadvantage of using such a tubbing formwork is in turn the fact that at a fixed wall thickness of the concrete must be filled via a mortar pump, which is connected due to the relatively thin filler neck used with great difficulty.
Bei den genannten Anwendungsfällen der oben genannten Art bestand also der Nachteil, dass der Flüssigbeton in einen geschlossenen Kasten eingefüllt werden musste, und zwar unter hohem Druck, und dass nach Erhalt der Grünstandsfestigkeit entschalt wurde.In the applications mentioned above of the type mentioned above, there was the disadvantage that the liquid concrete had to be filled in a closed box, under high pressure, and that was de-energized after receiving the green strength.
Kennzeichnend für die beiden oben genannten Verfahren war, dass auch zur Herstellung von halboffenen Betonteilen der Faserbeton oder Flüssigbeton in eine in sich vollkommen geschlossene Form eingespritzt wurde, was mit dem Nachteil verbunden war, dass für eine gleichmäßige Verteilung des Betons in der vollkommen geschlossenen Form nicht immer gesorgt werden konnte.Characteristic of the two methods mentioned above was that also for the production of semi-open concrete parts of fiber concrete or liquid concrete was injected into a completely self-contained form, which was associated with the disadvantage that not for a uniform distribution of the concrete in the fully closed form could always be taken care of.
Deshalb sah die
Der Erfindung liegt deshalb die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zur Herstellung von halboffenen Betonteilen der eingangs genannten Art so weiterzubilden, dass eine wesentlich bessere Qualität des Betonteils erreicht wird und ein einfacherer Verfahrensablauf gegeben ist.The invention is therefore the object of developing a method and apparatus for producing semi-open concrete parts of the type mentioned so that a much better quality of the concrete part is achieved and a simpler process flow is given.
Zur Lösung der gestellten Aufgabe ist die Erfindung durch die technische Lehre des Anspruches 1 gekennzeichnet.To solve the problem, the invention is characterized by the technical teaching of claim 1.
Wesentliches Merkmal der Erfindung ist, dass nun erfindungsgemäß keine in sich geschlossene Form verwendet wird, sondern eine halboffene Form, die einen großen nach oben geöffneten Einfüllraum ausbildet, über den großflächig der Beton (Flüssigbeton) einfließen kann und dass nach erfolgter Befüllung der nach oben halboffenen Form mit einem die obere Öffnung abschließenden Presselement ein Druck von oben auf die eingefüllte Betonmasse ausgeübt wird, um so das überschüssige Wasser nach allen Seiten hin aus der Form auszupressen.An essential feature of the invention is that now according to the invention no self-contained form is used, but a semi-open mold, which forms a large upwardly open Einfüllraum, on the large surface of the concrete (liquid concrete) can flow and that after completion of the top half open Form with a top opening the final pressing element, a pressure is exerted from above on the filled concrete mass, so as to squeeze the excess water in all directions out of the mold.
Mit der gegebenen technischen Lehre ergibt sich der wesentliche Vorteil, dass nun Dank der Verwendung einer halboffenen Form der Beton nicht mehr unter hohem Druck eingefüllt werden muss, sondern er kann als Flüssigbeton eingegossen werden, wodurch er sich selbsttätig gleichmäßig an allen Formennestern und allen Formenhohlräumen verteilt und eine gleichmäßige Ausfüllung der Gießform gewährleistet und dass nach erfolgtem Auffüllen der Form dann mit einem Presselement der Formhohlraum nach oben abgeschlossen wird und das Presselement in den Formhohlraum hineindrückt, um so die den Beton in dem Formhohlraum zu verfestigen und das überschüssige Wasser über zugeordnete Filterbleche nach außen abzuleiten.With the given technical teaching, there is the significant advantage that now thanks to the use of a semi-open mold, the concrete no longer has to be filled under high pressure, but it can be poured as liquid concrete, whereby it distributes itself automatically evenly on all mold nests and all mold cavities and ensures even filling of the mold and that after completion of filling the mold with a pressing member of the mold cavity is closed up and pushes the pressing element into the mold cavity, so as to solidify the concrete in the mold cavity and the excess water on associated filter plates after derive externally.
In einer bevorzugten Ausgestaltung der vorliegenden Erfindung wird ein Presselement verwendet, um so den Formenraum nach oben hin abzuschließen und den dort eingefüllten Beton gegen die in dem Formraum angeordneten Filterbleche zu verdichten und das Wasser auszupressen.In a preferred embodiment of the present invention, a pressing element is used so as to close the mold space upwards and to compress the concrete poured there against the arranged in the mold space filter plates and squeeze out the water.
Damit ergibt sich eine wesentliche bessere Qualität der so hergestellten halboffenen Betonfertigteile, denn durch die gleichmäßige praktisch druckfreie Verteilung des Flüssigbetons erfolgt eine gleichmäßige Ausfüllung des Formraumes und somit ein wesentlich besseres Gefüge des so hergestellten Fertigbetonteils.This results in a significantly better quality of semi-finished precast concrete parts thus produced, because the uniform virtually pressure-free distribution of liquid concrete is a uniform filling of the mold space and thus a much better microstructure of the finished concrete part thus prepared.
Unter dem Begriff eines Flüssigbetons wird verstanden, dass es sich hierbei um einen üblichen fließfähigen Beton handelt, der in bekannter Weise aus Zuschlagstoffen, Zement und Wasser besteht, wobei ein hoher Anteil an Wasser vorhanden ist.The term liquid concrete is understood to mean that it is a conventional flowable concrete, which in a known manner consists of aggregates, cement and water, wherein a high proportion of water is present.
Der Flüssigbeton hat ein Ausbreitmaß von etwa 70 bis 80 cm und ist somit gut fließfähig.The liquid concrete has a slump of about 70 to 80 cm and is therefore very fluid.
Vergleicht man einen solchen Flüssigbeton mit einem erdfeuchten Beton, dessen Verwendung ebenfalls zur Herstellung von halboffenen Betonfertigteilen bekannt ist, dann besteht bei der Verwendung von erdfeuchtem Beton und zugeordneten Formen, in die der erdfeuchte Beton eingefüllt werden muss, der Nachteil, dass der erdfeuchte Beton nur sehr schwierig in die Form einzubringen ist, hierbei Vibrationswerkzeuge verwendet werden müssen und im Übrigen die gesamte Form ebenfalls noch auf Vibriertischen angeordnet ist, um eine gleichmäßige Verteilung eines erdfeuchten Betons zu erreichen, mit dem es deshalb auch nur möglich ist, eine minimale Wandstärke von 5 cm nicht zu unterschreiten, während bei der Verwendung von Flüssigbeton nach der vorliegenden Erfindung erfindungsgemäß nun Wandstärken von kleiner als 1 cm erreichbar sind.If one compares such a liquid concrete with an earth-moist concrete, the use of which is likewise known for the production of semi-open precast concrete parts, then the use of earth-moist concrete and associated forms into which the earth-moist concrete must be filled has the disadvantage that the earth-moist concrete is very difficult to bring into the mold, this vibration tools must be used and otherwise the entire shape is also still arranged on vibrating tables in order to achieve a uniform distribution of a slightly moist concrete, with which it is therefore only possible, a minimum wall thickness of 5 cm, while in the use of liquid concrete according to the present invention according to the invention now wall thicknesses of less than 1 cm can be achieved.
Dem Flüssigbeton können in an sich bekannter Weise auch Faserstoffe zugefügt werden, um so einen Faserbeton zu erreichen, der eine hohe Bruchfestigkeit am ausgehärteten Teil zeigt. Dies ist ein wesentlicher Vorteil gegenüber bekannten anderen Herstellungsverfahren, die einen sogenannten Polymer-Beton verwenden, der im Wesentlichen aus einem Sand-Harz-Gemisch besteht, welches Gemisch über eine Temperaturerhöhung ausgehärtet wird und nach der Herstellung wie Glas ausgebildet ist und natürlich bei Einwirkung von Stößen auch zerbricht.The liquid concrete can be added in a conventional manner and fibrous materials, so as to achieve a fiber concrete, which shows a high breaking strength on the cured part. This is a significant advantage over known other manufacturing processes that use a so-called polymer concrete, which consists essentially of a sand-resin mixture, which mixture is cured by an increase in temperature and formed after manufacture such as glass and of course upon exposure to Shocks also breaks.
Die Verwendung von mit Fasern verstärktem Flüssigbeton hat also wesentliche Vorteile bei der Verwendung des vorliegenden Verfahrens.The use of fiber reinforced liquid concrete thus has significant advantages in the use of the present method.
Im Vergleich zum älteren Stand der Technik (
Erfindungsgemäß ist nun vorgesehen, dass in dem Formkasten nun eine bevorzugt aus Metall bestehende Trägerform eingesetzt wird, welche die Innenwandung des damit hergestellten halboffenen Betonfertigteils ausbildet.According to the invention it is now provided that in the mold box now a preferably made of metal carrier mold is used, which forms the inner wall of the semi-finished precast concrete element produced therewith.
Damit besteht der wesentliche Vorteil, dass nun die Innenwandung des so hergestellten Betonfertigteils genau der Oberflächenstruktur der Trägerform entspricht und besonders glatt und mit hoher Qualität ausgebildet sein kann. Weiterhin besteht der Vorteil, dass in der Trägerform bestimmte Formgebungen vorgesehen werden können, wie z.B. Sicken, Schlitze, Aussparungen und dergleichen mehr, die genau dann im halboffenen Betonfertigteil eingebracht sind. Ein derartiger Vorteil bestand bei dem genannten Stand der Technik nicht, weil dort eine Trägerform aus Metall nicht verwendet werden konnte.This has the significant advantage that now the inner wall of the prefabricated concrete part thus produced corresponds exactly to the surface structure of the support shape and can be particularly smooth and formed with high quality. Furthermore, there is the advantage that certain shapes can be provided in the carrier form, such as beads, slots, recesses and the like more, which are then introduced in semi-open precast concrete part. Such an advantage did not exist in the cited prior art, because there could not be used a carrier form made of metal.
Selbstverständlich ist die Erfindung nicht auf die Verwendung einer Trägerform aus einem Metallblech beschränkt. Es können auch Kunststoffformen, Holzformen und dergleichen verwendet werden, um eben die Oberflächenstruktur der Trägerform auf das Betonfertigteil zu übertragen.Of course, the invention is not limited to the use of a carrier form of a metal sheet. Plastic molds, wood forms and the like may also be used to transfer the surface structure of the carrier mold to the precast concrete element.
Somit ergeben sich durch die Verwendung einer Trägerform in einem halboffenen Formkasten die Vorteile, dass eine besonders hohe Oberflächengüte des Betonfertigteils erreicht wird.Thus, the use of a carrier form in a semi-open mold box, the advantages that a particularly high surface quality of the precast concrete part is achieved.
Durch die Verwendung eines nach oben geöffneten Formkastens, in den eine Trägerform eingebracht wird, auf deren Oberseite dann der Beton eingefüllt wird, ergibt sich der weitere Vorteil, dass in den sich dadurch gebildeten Einfüllraum, der hier nach oben geöffnet ist, die Möglichkeit besteht, beliebige Einlage- oder Einschalelemente als verlorene Elemente einzubringen. Es können z. B. Gewebematten, Anschlussteile, Vliese, Hohlkörper und andere Teile eingebracht werden, die in dem dann fertig gestellten Betonfertigteil eingebaut sind.By using a mold box open at the top into which a carrier mold is introduced, on the upper side of which the concrete is then filled, there is the further advantage that there is the possibility in the filling space formed thereby, which is open upwards, to introduce any insert or insertion elements as lost elements. It can z. As fabric mats, fittings, fleeces, hollow bodies and other parts are incorporated, which are then installed in the precast concrete finished part.
Diese Möglichkeit, des Einbringens zusätzlicher Einbauelemente in eine Form war bei der
Oben stehend wurde ausgeführt, dass der Formkasten im Wesentlichen aus einem umlaufenden Rahmen besteht, der einen mit Schlitzen versehenen Boden aufweist und in diesen Formkasten mindestens eine Trägerform eingesetzt wird, um so die Trägerform von unten (fußseitig) bis nach oben hin gehend mit Beton aufzufüllen.It has been stated above that the molding box essentially consists of a peripheral frame which has a slotted bottom and at least one carrier mold is inserted into this molding box so as to fill the carrier form with concrete from the bottom (foot side) to the top ,
In einer Weiterbildung der vorliegenden Erfindung ist es nach dem Vorrichtungsmerkmal vorgesehen, dass die Wände des Formkastens verschiebbar ausgebildet sind, um eine Entformung des fertig gestellten Betonfertigteiles zu ermöglichen.In one embodiment of the present invention, it is provided by the device feature that the walls of the molding box are designed to be displaceable in order to enable demolding of the finished precast concrete finished.
Hierbei wird es bevorzugt, wenn die verschiebbaren Wände durch Druckplatten gebildet sind, welche Druckplatten ihrerseits mit Druckelementen versehen sind, welche Druckelemente mit Stößeln verbunden sind, so dass diese in horizontale Richtung verfahrbar ausgebildet sind.In this case, it is preferred if the displaceable walls are formed by pressure plates, which pressure plates are in turn provided with pressure elements, which pressure elements are connected to tappets, so that they are designed to be movable in the horizontal direction.
Auf diese Weise ist eine einfache Entschalung der fertig gestellten Betonfertigteile aus dem Formkasten möglich, weil sowohl die Längsbalken als auch die Stirnbalken des Formkastens verschiebbar als Druckelemente ausgebildet sind.In this way, a simple decalcifying the finished precast concrete parts from the molding box is possible because both the longitudinal beams and the end beam of the mold box are slidably formed as pressure elements.
Auf diese Weise kann jede Wandung des Formkastens von dem fertig gestellten Betonfertigteil weggefahren werden und zugestellt werden, um eine einwandfreie Entformung zu ermöglichen.In this way, each wall of the molding box can be moved away from the completed precast concrete part and delivered to allow proper demolding.
Wichtig ist auch noch, dass an der Innenseite der Druckelemente Filterplatten angeordnet sind, die bevorzugt aus Stahlplatten gebildet sind. Die Filterplatten haben bevorzugt eine Lochung oder Schlitzung von z. B. 30 µm, um zu erreichen, dass lediglich das Wasser bei Einbringung von Druck von der Oberpresse entweicht und nicht das im Zement eingebundene Korn.It is also important that filter plates are arranged on the inside of the printing elements, which are preferably formed from steel plates. The filter plates preferably have a perforation or slit of z. B. 30 microns, in order to achieve that only the water escapes with the introduction of pressure from the top press and not the embedded grain in the cement.
Die Verwendung von Druckplatten in dem Formkasten, die in Richtung auf den Einfüllraum zustellbar und wegstellbar sind, hat den weiteren Vorteil, dass die Druckplatten innenseitig noch mit zugeordneten Profilen oder Vorsprüngen versehen werden können, die auf die Seitenwände des halbfertigen Betonteils übertragen werden.The use of pressure plates in the molding box, which are deliverable and wegstellbar in the direction of the Einfüllraum, has the further advantage that the pressure plates can be provided on the inside still with associated profiles or projections, which are transmitted to the side walls of the semi-finished concrete part.
Wenn beispielsweise in den Formraum hineinspringende Vorsprünge an den Druckplatten angeordnet sind, ergeben sich entsprechende rinnenförmige Ausnehmungen an der Seitenwand des halbfertigen Betonteils, was Gewicht spart und eine besondere Formgebung hervorruft.For example, if protrusions projecting into the mold space are arranged on the pressure plates, corresponding groove-shaped recesses result on the side wall of the semi-finished concrete part, which saves weight and causes a special shape.
Somit ist man in der Formgebung der Seitenwände relativ frei und kann auch verschiedene Vorsprünge, Rücksprünge und andere Elemente an den Seitenwänden einbringen, weil dies nur eine Veränderung an der druckaufbringenden Seite der jeweiligen Druckplatte erfordert.Thus, one is relatively free in the shaping of the side walls and can also introduce various projections, recesses and other elements on the side walls, because this only requires a change on the pressure-applying side of the respective pressure plate.
Das gleiche gilt natürlich auch für die Stirnplatten, weil die Stirnplatten ebenfalls als Druckplatten ausgebildet sind und an diesen Stellen ebenfalls in den Formenraum hineinragende Vorsprünge oder Rücksprünge angeordnet werden können.Of course, the same also applies to the end plates, because the end plates are also formed as printing plates and protrusions or recesses protruding into the mold space can also be arranged at these locations.
Eine solche Einbringung von Hinterschneidungen oder Vorsprüngen konnte mit dem vorher genannten Verfahren nicht durchgeführt werden, weil die verfahrbaren Innenwände des Formkastens nicht in der Weise verfahrbar werden konnten, um eine vollständige Entformung auch von dort angebrachten Hinterschneidungen zu gewährleisten.Such an introduction of undercuts or protrusions could not be performed with the aforementioned method, because the movable inner walls of the molding box could not be moved in such a way to ensure complete demoulding also from there placed undercuts.
Nun können nach dem erfindungsgemäßen Verfahren sowohl Wülste und Hinterschneidungen an der Innenseite des Betonfertigteils über die Gestaltung der Trägerform eingebracht werden als auch außenseitig über die Gestaltung der längsseitig und stirnseitig anliegenden Druckplatten.Now, both beads and undercuts on the inside of the precast concrete part on the design of the carrier form can be introduced by the inventive method as well as the outside on the design of the longitudinal side and the front side adjacent pressure plates.
Nach einer Ausgestaltung des erfindungsgemäßen Verfahrens ist es vorgesehen, die erfindungsgemäß vorgesehenen Formenkästen mit den oben beschriebenen Merkmalen in einem ringförmig angeordneten Verfahrensablauf einzubinden, so dass ein getaktetes Verfahren verwendet wird, das eine Mehrzahl von erfindungsgemäßen Formenkästen verwendet.According to one embodiment of the method according to the invention, it is provided to incorporate the molding boxes provided according to the invention with the features described above in a ring-shaped process sequence, so that a clocked method is used which uses a plurality of molding boxes according to the invention.
Bei der Verwendung eines einzigen Formkastens hat man ohnedies immer die hierfür notwendigen Verfahrensschritte, nämlich das Einschalen des Formkastens, das Einfüllen des Mörtels, das Pressen im halboffenen Formenraum, das Ausschalen und das Reinigen der Form.When using a single mold box you will always have the necessary process steps, namely the molding of the mold box, the filling of the mortar, the pressing in the half-open mold space, stripping and cleaning the mold anyway.
Wenn man nun auf einer Ringanlage eine Mehrzahl derartiger Formenkästen getaktet über Längsförderer hintereinander liegend anordnet, kann man in einem Ringverfahren in sehr kurzer Zeit eine hohe Produktionsleistung erzielen, weil beispielsweise bei der Verwendung von 5 Formkästen eine fünffach gesteigerte Produktionsleistung gegenüber der Verwendung eines einzigen Formkastens erzielt wird.If you now arranged on a ring system a plurality of such mold boxes clocked longitudinal conveyor one behind the other, you can in a Ring method in a very short time to achieve high production performance, for example, when using 5 molding boxes a five-fold increased production performance compared to the use of a single mold box is achieved.
Auf diese Weise werden also z. B. 5 Formkästen auf der ringförmigen Anlage an unterschiedlichen Stationen positioniert und die Anlage wird dann in Betrieb genommen, um so jeden Formkasten einer bestimmten Station zuzuführen.In this way, so z. B. 5 molding boxes positioned on the annular system at different stations and the system is then put into operation, so as to supply each molding box a particular station.
Es handelt sich also um ein ringförmiges Taktverfahren, bei dem eine Mehrzahl von Formkästen im Ringumlauf taktweise der jeweiligen Station zugeführt werden.It is therefore an annular cycle method in which a plurality of molding boxes are cyclically fed in the ring circulation of the respective station.
