Definitions
- the invention relates to a support method for supporting a reinforcement construction, a manufacturing method for producing precast concrete parts and an automatic laying machine for carrying out the support method.
- spacers in the form of e.g. filed different sized rings or plastic strips and then arranged on these the reinforcing elements.
- the manual positioning of the spacers is based on experience, with the result that in some cases too many spacers are used. This increases the risk for the formation of cavities, since the spacers are coated together with the reinforcing elements with the concrete, which adversely affects the quality of the precast concrete to be produced. In addition, this will cause higher costs because on the one hand unnecessary spacers are consumed and on the other hand, when recycling the precast concrete an increased effort is necessary to extract the spacers back from the precast concrete part.
- the object of the present invention is therefore to provide a comparison with the prior art improved support method for supporting a reinforcement structure, this support method making use of manufacturing process for the production of precast concrete and an automatic laying machine for performing the improved support method, wherein the support method according to the invention in particular characterized by an improved quality of the precast concrete elements, a cost saving and a more environmentally friendly recycling of the precast concrete parts.
- the positions for supporting the reinforcement structure are calculated and the spacers are then placed in the calculated positions for supporting the reinforcement construction during the third process step, it is ensured that an optimal amount of spacers is used and these the optimal positions are arranged.
- an optimal amount of spacers is used and these the optimal positions are arranged.
- the data provided in the course of the first process step of a reinforcement construction designed for the prefabricated concrete part to be produced may be, for example, the construction, the geometry and the weight of the reinforcement construction.
- the reinforcement structures used are constructed of longitudinal bars, transverse bars and / or lattice girders, depending on the precast concrete part recesses may be provided for example for windows or doors.
- the outer contours of the reinforcement structure can already reflect the outer contours of the precast concrete part to be produced, that is, for example, inclined surfaces or the like.
- Used lattice girders typically include upper and lower girder assemblies and diagonal straps extending therebetween. The exact structure of the lattice girders may also form part of the data provided.
- the diameter also plays a role and the material composition of the transverse and longitudinal bars or lattice girders used and the relative arrangement of these elements to one another.
- All of this data may be provided during the first process step, e.g. in the form of a CAD file.
- the term "providing” also includes solutions in which the data is generated by a program-controlled electronic computer in the course of the first method step or retrieved from a database. This can be the same program-controlled electronic computer system that is also used in the second method step.
- the calculation of the positions for supporting the reinforcement construction carried out in the course of the second method step may, in addition to the data of the reinforcement construction provided in the course of the first method step, also take into account further parameters, such as e.g. the carrying capacity of the spacers used to support the reinforcement structure.
- the calculation of the positions can be done in different ways:
- precast element types can be treated diversified. For example, based on simplified static models tailored to the particular element type, one could design an algorithm suitable for the position calculation.
- the reinforcement structure in the calculation of the positions for supporting the reinforcement construction in the course of the second process step can be subdivided into support areas, wherein preferably each support area is assigned in each case exactly one spacer. It has proved to be advantageous to iteratively move the boundaries of the support areas in the calculation of the positions for supporting the reinforcement construction in the course of the second process step.
- the placement can be done manually, with a marking device can be used to mark the positions. This may be e.g. to act a plotter or a modulated line laser or the like.
- placement may also be automatic, e.g. done by means of a laying machine.
- a reinforcement construction made according to the data is then deposited on the positioned spacers.
- the support method for supporting a reinforcement construction is substantially completed.
- the reinforcement construction placed on the spacers - together with the spacers - is embedded in a concrete mass.
- the spacers are preferably placed on a pallet provided with formwork elements and the production process is carried out in a pallet circulating system.
- the laying machine comprises at least one longitudinal and / or transverse movable placement device and a control unit, which is designed to control the at least one placement device such that a spacer is stored at a precalculated position.
- the control unit may be, for example, the program-controlled electronic computer system used in the course of the second method step.
- the at least one placing device comprises at least one device for detecting the height of the spacers, preferably using a laser means. This ensures that spacers are laid with a height suitable for a given concrete cover. Operating errors during manual refilling of spacers of a wrong type can be detected in this way and subsequently resulting negative consequences can be avoided.
- the supporting method 21 for supporting a reinforcement construction can be integrated into a production method 22 for the production of precast concrete parts, wherein in a subsequent process steps 23 to 26 of the support method 21 subsequent step 27, the embedded on the spacers reinforcement construction is embedded in a concrete mass.
- FIG. 2a shows schematically in plan view an example of a reinforcing structure 1, which is designed for the production of a precast concrete part in the form of a polystyrene blanket.
- the reinforcement structure 1 is composed of a plurality of longitudinal bars 28, substantially perpendicular thereto oriented transverse bars 29 and lattice girders 30, which may be constructed, for example, of an upper and a lower chord and extending therebetween diagonal straps.
- the data of this reinforcement structure 1 are provided in the course of the first method step 23.
- positions 33 and 34 (cf. FIG. 2b ) to support the reinforcement structure 1 as a function of the provided data of the reinforcement structure 1.
- the type of element is dominated by the five longitudinal lines on which the longitudinal reinforcement concentrates and on which the lattice girders 30 are arranged.
- a reasonable assumption as a starting point for the calculation is thus to position the spacers 4 exclusively along these five main lines in the longitudinal direction 33.
- a plurality of spacers 4 along these longitudinal lines are distributed as a test and it is approximately the sagging behavior of these longitudinal lines - without consideration of the transverse bars 29 - calculated and compared with predetermined limits.
- the positions 33, 34 of the spacers 4 are moved iteratively, again the sagging behavior is calculated and compared with limit values until such time as a maximum distance 31 of the first spacer 4 from the beginning of the reinforcement structure 1 and the maximum distance 32 of the spacers 4 along the longitudinal line has determined at a tolerable sag behavior.
- the values 31 and 32 are calculated with a certain tolerance, which is dependent on the distance 44 of the transverse bars 29, since it makes sense for static reasons, not to set the spacers 4 exactly to the 31 and 32 predetermined positions, but on the to move to the nearest crossing point.
- this calculation method it is possible to calculate a set of substantially optimal positions 33, 34 for supporting the reinforcement structure 1 depending on the provided data of the reinforcement structure 1, this set of positions 33, 34 a minimum number of spacers 4 with a simultaneously tolerable Sagging behavior of the reinforcement structure 1, which subsequently has an effect on the quality of the precast concrete part to be produced.
- a reinforcement construction 1 manufactured according to the data is placed on the spacers 4.
- the result of this third and fourth process step 25 or 26 is shown schematically in FIG FIG. 2b shown, in addition, also the inner contours of formwork elements 10 are indicated, which corresponds to the outer contour of a manufactured by embedding the deposited on the spacers 4 reinforcement structure 1 in a concrete mass and the curing of the concrete mass precast concrete.

- the data of this reinforcement structure 2 are provided in the form of CAD data.
- positions 33 and 34 for supporting the reinforcement structure 2 as a function of this provided data of the reinforcement structure 2 are calculated in a program-controlled electronic computer system.
- each support portion 5 each exactly one spacer 4 is assigned, which carries at least one transverse bar 29 or longitudinal bar 28.
- Each of these supporting rods depends downwards from the point of support. This sagging is essentially depending on the weight of the supporting rod and the weight of the welded supporting rods. In the course of the calculation, it is required that a parametrisierbares torque maximum may not be exceeded, wherein the torque depends on the diameter of the supporting rods.
- the load of the bars carried is divided among all the supporting bars.
- Each support rod resting on a spacer is calculated.
- each supported rod is again considered a bearing rod and calculated until all rods are worn. The deflection of the rods carried depends on their diameter and the weight of the rods welded to them and the resulting torque.
- This calculation is performed for support areas 5, in each of which a spacer 4 is arranged.
- the division into the support areas 5 takes place, for example, starting from one side of the reinforcement structure 2.
- the initial size of each support area 5 can be parameterized.
- the size of the carrying areas 5 is iteratively changed during the calculation in order to come as close as possible to the predetermined torque limit.
- the boundaries 16 of each support area 5 are given on the one hand by the boundaries of the reinforcement structure 2 outside and inside (recesses for windows, doors or the like) and on the other hand by the calculated loads and the resulting boundaries to other support areas. 5
- some of the apertures in the support surface 40 are arranged such that they provide at least space for supports 42 of another identical spacer 4 and thus at least two spacers 4 are stackable and the common fictitious volume of the stacked spacers 4 relative to the notional volume of a spacer 4 is negligible, with the stacked spacers 4 are in principle in the same position and only rotated or offset laterally, so their Support surface 40 are parallel to each other.
- the grid-like support surface 40 is round in the present case.
- the supports 42 form the measure defining the concrete cover. Depending on the required concrete cover of the reinforcement structures 1, 2, the supports 42 may be longer or shorter.

Description
Die Erfindung betrifft ein Abstützverfahren zur Abstützung einer Bewehrungskonstruktion, ein Herstellungsverfahren zur Herstellung von Betonfertigteilen sowie einen Verlegeautomaten zur Durchführung des Abstützverfahrens.The invention relates to a support method for supporting a reinforcement construction, a manufacturing method for producing precast concrete parts and an automatic laying machine for carrying out the support method.
Um bei der Herstellung von Betonfertigteilen sicherzustellen, dass die darin eingelagerten Bewehrungselemente eine ausreichende Betonüberdeckung aufweisen, werden auf einem Untergrund manuell Abstandhalter in Form von z.B. verschieden großen Ringen oder Kunststoffstreifen abgelegt und auf diesen dann die Bewehrungselemente angeordnet. Dabei erfolgt die manuelle Positionierung der Abstandhalter anhand von Erfahrungswerten, was zur Folge hat, dass zum Teil zu viele Abstandhalter verwendet werden. Dadurch erhöht sich die Gefahr für die Bildung von Hohlräumen, da die Abstandhalter zusammen mit den Bewehrungselementen mit dem Beton ummantelt werden, was sich nachteilig auf die Qualität des herzustellenden Betonfertigteils auswirkt. Außerdem werden hierdurch höhere Kosten verursacht, da zum einen unnötige Abstandhalter verbraucht werden und zum anderen beim Recycling der Betonfertigteile ein erhöhter Aufwand notwendig ist, um die Abstandhalter wieder aus dem Betonfertigteil zu extrahieren.In order to ensure, in the production of precast concrete parts, that the reinforcing elements embedded therein have sufficient concrete cover, spacers in the form of e.g. filed different sized rings or plastic strips and then arranged on these the reinforcing elements. The manual positioning of the spacers is based on experience, with the result that in some cases too many spacers are used. This increases the risk for the formation of cavities, since the spacers are coated together with the reinforcing elements with the concrete, which adversely affects the quality of the precast concrete to be produced. In addition, this will cause higher costs because on the one hand unnecessary spacers are consumed and on the other hand, when recycling the precast concrete an increased effort is necessary to extract the spacers back from the precast concrete part.
Die Aufgabe der vorliegenden Erfindung besteht somit darin, ein gegenüber dem Stand der Technik verbessertes Abstützverfahren zur Abstützung einer Bewehrungskonstruktion, ein dieses Abstützverfahren sich zu Nutze machendes Herstellungsverfahren zur Herstellung von Betonfertigteilen sowie einen Verlegeautomaten zur Durchführung des verbesserten Abstützverfahrens anzugeben, wobei sich das erfindungsgemäße Abstützverfahren insbesondere durch eine verbesserte Qualität der Betonfertigteile, eine Kosteneinsparung sowie ein umweltschonenderes Recycling der Betonfertigteile auszeichnet.The object of the present invention is therefore to provide a comparison with the prior art improved support method for supporting a reinforcement structure, this support method making use of manufacturing process for the production of precast concrete and an automatic laying machine for performing the improved support method, wherein the support method according to the invention in particular characterized by an improved quality of the precast concrete elements, a cost saving and a more environmentally friendly recycling of the precast concrete parts.
Diese Aufgabe wird durch die Merkmale der unabhängigen Ansprüche 1, 9 und 10 gelöst.This object is solved by the features of
Demnach ist es vorgesehen, dass bei dem Abstützverfahren zur Abstützung einer Bewehrungskonstruktion bei der Herstellung von Betonfertigteilen
- in einem ersten Verfahrensschritt Daten einer für das herzustellende Betonfertigteil ausgelegten Bewehrungskonstruktion bereitgestellt werden,
- in einem zweiten Verfahrensschritt in einer programmgesteuerten, elektronischen Rechenanlage Positionen zur Abstützung der Bewehrungskonstruktion in Abhängigkeit der bereitgestellten Daten der Bewehrungskonstruktion berechnet werden,
- in einem dritten Verfahrensschritt Abstandhalter an den berechneten Positionen zur Abstützung der Bewehrungskonstruktion platziert werden, und
- in einem vierten Verfahrensschritt eine entsprechend den Daten gefertigte Bewehrungskonstruktion auf den Abstandhaltern abgelegt wird.
- in a first method step, data of a reinforcement construction designed for the prefabricated concrete part to be produced are provided,
- in a second method step, in a program-controlled, electronic computing system, positions for supporting the reinforcement construction are calculated as a function of the provided data of the reinforcement construction,
- in a third method step spacers are placed at the calculated positions for supporting the reinforcement construction, and
- in a fourth method step, a reinforcement construction made according to the data is deposited on the spacers.
Dadurch, dass im Zuge des zweiten Verfahrensschritts die Positionen zur Abstützung der Bewehrungskonstruktion berechnet werden und die Abstandhalter dann im Zuge des dritten Verfahrensschritts an den berechneten Positionen zur Abstützung der Bewehrungskonstruktion platziert werden, wird sichergestellt, dass eine optimale Menge an Abstandhaltern verwendet wird und diese an den optimalen Positionen angeordnet sind. Dadurch können einheitlichere Betonfertigteile mit einer bestimmten Betonüberdeckung und weniger Hohlräumen gefertigt, die Kosten reduziert und beim Recycling am Ende der Lebensdauer der Betonfertigteile die Umwelt geschont werden.In the course of the second process step, the positions for supporting the reinforcement structure are calculated and the spacers are then placed in the calculated positions for supporting the reinforcement construction during the third process step, it is ensured that an optimal amount of spacers is used and these the optimal positions are arranged. As a result, more uniform precast concrete elements can be produced with a specific concrete cover and fewer cavities, costs can be reduced, and the environment can be spared in recycling at the end of the life of the precast concrete elements.
Bei den im Zuge des ersten Verfahrensschritts bereitgestellten Daten einer für das herzustellende Betonfertigteil ausgelegten Bewehrungskonstruktion kann es sich beispielsweise um den Aufbau, die Geometrie und das Gewicht der Bewehrungskonstruktion handeln. Typischerweise sind die verwendeten Bewehrungskonstruktionen aus Längsstäben, Querstäben und/oder Gitterträgern aufgebaut, wobei je nach Betonfertigteil Aussparungen z.B. für Fenster oder Türen vorgesehen sein können. Die äußeren Umrisse der Bewehrungskonstruktion können bereits die äußeren Umrisse des herzustellenden Betonfertigteils, also beispielsweise Schrägflächen oder dergleichen, widerspiegeln. Zum Einsatz kommendeGitterträger weisen in der Regel eine Ober- und eine Untergurtanordnung und dazwischen verlaufende Diagonalgurte auf. Der genaue Aufbau der Gitterträger kann ebenfalls einen Teil der bereitgestellten Daten bilden. Eine Rolle spielen auch der Durchmesser und die Materialzusammensetzung der verwendeten Quer- und Längsstäbe bzw.Gitterträger sowie die relative Anordnung dieser Elemente zueinander.The data provided in the course of the first process step of a reinforcement construction designed for the prefabricated concrete part to be produced may be, for example, the construction, the geometry and the weight of the reinforcement construction. Typically, the reinforcement structures used are constructed of longitudinal bars, transverse bars and / or lattice girders, depending on the precast concrete part recesses may be provided for example for windows or doors. The outer contours of the reinforcement structure can already reflect the outer contours of the precast concrete part to be produced, that is, for example, inclined surfaces or the like. Used lattice girders typically include upper and lower girder assemblies and diagonal straps extending therebetween. The exact structure of the lattice girders may also form part of the data provided. The diameter also plays a role and the material composition of the transverse and longitudinal bars or lattice girders used and the relative arrangement of these elements to one another.
All diese Daten können im Zuge des ersten Verfahrensschritts bereitgestellt werden und zwar z.B. in Form eines CAD-Files. Der Ausdruck "Bereitstellen" umfasst aber auch Lösungen, bei welchen die Daten von einer programmgesteuerten elektronischen Rechenanlage im Zuge des ersten Verfahrensschritts generiert werden oder aus einer Datenbank abgerufen werden. Dabei kann es sich um dieselbe programmgesteuerte elektronische Rechenanlage handeln, die auch im zweiten Verfahrensschritt zum Einsatz kommt.All of this data may be provided during the first process step, e.g. in the form of a CAD file. However, the term "providing" also includes solutions in which the data is generated by a program-controlled electronic computer in the course of the first method step or retrieved from a database. This can be the same program-controlled electronic computer system that is also used in the second method step.
Die im Zuge des zweiten Verfahrensschritts durchgeführte Berechnung der Positionen zur Abstützung der Bewehrungskonstruktion kann zusätzlich zu den im Zuge des ersten Verfahrensschritts bereitgestellten Daten der Bewehrungskonstruktion auch noch weitere Parameter berücksichtigen, wie z.B. die Tragfähigkeit der zur Abstützung der Bewehrungskonstruktion verwendeten Abstandhalter.The calculation of the positions for supporting the reinforcement construction carried out in the course of the second method step may, in addition to the data of the reinforcement construction provided in the course of the first method step, also take into account further parameters, such as e.g. the carrying capacity of the spacers used to support the reinforcement structure.
Die Berechnung der Positionen kann auf unterschiedliche Arten durchgeführt werden:The calculation of the positions can be done in different ways:
Es bietet sich zum Beispiel an, dass unterschiedliche Fertigteilelementtypen diversifiziert behandelt werden. Zum Beispiel könnte man basierend auf vereinfachten statischen Modellen, die auf den jeweiligen Elementtyp zugeschnitten sind, einen Algorithmus entwerfen, der für die Positionsberechnung geeignet ist.For example, different types of precast element types can be treated diversified. For example, based on simplified static models tailored to the particular element type, one could design an algorithm suitable for the position calculation.
Konkret bietet es sich an, die Abstandhalter im Zuge der Berechnung zunächst an je nach Elementtyp geeignet erscheinenden Positionen zu platzieren, anschließend das Durchhängeverhalten der Bewehrungskonstruktion in Abhängigkeit der bereitgestellten Daten dieser Bewehrungskonstruktion zu bestimmen und zu prüfen, ob dieses Durchhängeverhalten vorgegebenen Grenzwerten entspricht. Je nach Ergebnis dieser Überprüfung werden dann die Positionen der Abstandhalter iterativ verschoben und erneut das Durchhängeverhalten berechnet und mit Grenzwerten verglichen. Diese Schritte werden solange durchgeführt, bis keine substantielle Verbesserung, d.h. Reduktion der Anzahl an Abstandhaltern bei gleichzeitig noch tolerierbarem Durchhängeverhalten der Bewehrungskonstruktion, mehr erzielbar ist.Specifically, it is advisable to first place the spacers in the course of the calculation to appear appropriate depending on the element type positions, then to determine the sag behavior of the reinforcement structure depending on the provided data of this reinforcement construction and to check whether this sag behavior corresponds to predetermined limits. Depending on the result of this check, the positions of the spacers are then moved iteratively and the sag behavior is again calculated and compared with limit values. These steps are carried out until no substantial improvement, ie reduction of the number of spacers with still tolerable sag behavior of the reinforcement construction, is more achievable.
Als günstig hat es sich auch herausgestellt, bei der Berechnung in Abhängigkeit vom Durchhängeverhalten der Bewehrungskonstruktion ausgeübte Drehmomente zu berechnen und diese mit vorgegebenen Grenzwerten zu vergleichen.It has also proved to be favorable to calculate the torques exerted in the calculation as a function of the sagging behavior of the reinforcement construction and to compare these with given limit values.
Ergänzend oder alternativ kann die Bewehrungskonstruktion bei der Berechnung der Positionen zur Abstützung der Bewehrungskonstruktion im Zuge des zweiten Verfahrensschrittes in Tragebereiche unterteilt werden, wobei vorzugsweise jedem Tragebereich jeweils genau ein Abstandhalter zugeordnet wird. Dabei hat es sich als vorteilhaft erwiesen, die Grenzen der Tragebereiche bei der Berechnung der Positionen zur Abstützung der Bewehrungskonstruktion im Zuge des zweiten Verfahrensschrittes iterativ zu verschieben.Additionally or alternatively, the reinforcement structure in the calculation of the positions for supporting the reinforcement construction in the course of the second process step can be subdivided into support areas, wherein preferably each support area is assigned in each case exactly one spacer. It has proved to be advantageous to iteratively move the boundaries of the support areas in the calculation of the positions for supporting the reinforcement construction in the course of the second process step.
Was die Platzierung der Abstandhalter an den berechneten Positionen im Zuge des dritten Verfahrensschritts betrifft, so haben sich folgende Lösungen als vorteilhaft herausgestellt:As regards the placement of the spacers at the calculated positions during the third process step, the following solutions have been found to be advantageous:
Einerseits kann die Platzierung manuell erfolgen, wobei zur Markierung der Positionen eine Markierungsvorrichtung zum Einsatz kommen kann. Bei dieser kann es sich z.B. um einen Plotter oder einen modulierten Strichlaser oder dergleichen handeln.On the one hand, the placement can be done manually, with a marking device can be used to mark the positions. This may be e.g. to act a plotter or a modulated line laser or the like.
Andererseits kann die Platzierung auch automatisch z.B. mittels eines Verlegeautomaten erfolgen.On the other hand, placement may also be automatic, e.g. done by means of a laying machine.
Im Zuge des vierten Verfahrensschritts wird dann eine entsprechend den Daten gefertigte Bewehrungskonstruktion auf den positionierten Abstandhaltern abgelegt.In the course of the fourth method step, a reinforcement construction made according to the data is then deposited on the positioned spacers.
Damit ist das Abstützverfahren zur Abstützung einer Bewehrungskonstruktion im Wesentlichen abgeschlossen. Um nun in weiterer Folge ein Betonfertigteil herzustellen, wird in einem nachfolgenden Verfahrensschritt die auf den Abstandhaltern abgelegte Bewehrungskonstruktion - zusammen mit den Abstandhaltern - in eine Betonmasse eingebettet.Thus, the support method for supporting a reinforcement construction is substantially completed. In order subsequently to produce a precast concrete part, in a subsequent process step, the reinforcement construction placed on the spacers - together with the spacers - is embedded in a concrete mass.
Bevorzugt werden die Abstandhalter im Zuge des dritten Verfahrensschritts auf einer mit Schalungselementen versehenen Palette platziert und das Herstellungsverfahren in einer Palettenumlaufanlage durchgeführt.In the course of the third method step, the spacers are preferably placed on a pallet provided with formwork elements and the production process is carried out in a pallet circulating system.
Wie eingangs ausgeführt, wird Schutz ebenfalls begehrt für einen Verlegeautomaten zur Durchführung des erfindungsgemäßen Abstützverfahrens, wobei der Verlegeautomat wenigstens eine in Längsrichtung und/oder Querrichtung verfahrbare Platziervorrichtung und eine Steuereinheit umfasst, welche dazu ausgebildet ist, die wenigstens eine Platziervorrichtung derart anzusteuern, dass ein Abstandhalter an einer vorberechneten Position abgelegt wird.As stated above, protection is also desired for a laying machine for carrying out the supporting method according to the invention, wherein the laying machine comprises at least one longitudinal and / or transverse movable placement device and a control unit, which is designed to control the at least one placement device such that a spacer is stored at a precalculated position.
Bei der Steuereinheit kann es sich beispielsweise um die im Zuge des zweiten Verfahrensschritts verwendete programmgesteuerte elektronische Rechenanlage handeln.The control unit may be, for example, the program-controlled electronic computer system used in the course of the second method step.
Vorteilhafterweise umfasst die wenigstens eine Platziervorrichtung wenigstens eine Vorrichtung zur Erfassung der Höhe der Abstandhalter, vorzusgweise unter Einsatz eines Lasermittels. So wird sichergestellt, dass Abstandhalter mit einer für eine vorgegebene Betonüberdeckung passenden Höhe verlegt werden. Bedienfehler beim manuellen Nachfüllen von Abstandhaltern eines falschen Typs können auf diese Weise erkannt und daraus in weiterer Folge erwachsende negative Konsequenzen vermieden werden.Advantageously, the at least one placing device comprises at least one device for detecting the height of the spacers, preferably using a laser means. This ensures that spacers are laid with a height suitable for a given concrete cover. Operating errors during manual refilling of spacers of a wrong type can be detected in this way and subsequently resulting negative consequences can be avoided.

Im konkreten Fall wird der Elementtyp von den fünf Längslinien, an denen sich die Längsbewehrung konzentriert und an denen die Gitterträger 30 angeordnet sind, dominiert. Eine sinnvolle Annahme als Ausgangspunkt für die Berechnung besteht somit darin, die Abstandhalter 4 ausschließlich entlang dieser fünf Hauptlinien in Längsrichtung 33 zu positionieren. Sodann werden mehrere Abstandhalter 4 entlang dieser Längslinien testweise verteilt und es wird näherungsweise das Durchhängeverhalten dieser Längslinien - ohne Berücksichtigung der Querstäbe 29 - berechnet und mit vorgegebenen Grenzwerten verglichen. Anschließend werden die Positionen 33, 34 der Abstandhalter 4 iterativ verschoben, erneut das Durchhängeverhalten berechnet und mit Grenzwerten verglichen und zwar solange, bis man einen maximalen Abstand 31 des ersten Abstandhalters 4 vom Anfang der Bewehrungskonstruktion 1 sowie den maximalen Abstand 32 der Abstandhalter 4 untereinander entlang der Längslinie bei einem noch tolerierbaren Durchhängeverhalten ermittelt hat. Die Werte 31 und 32 werden dabei mit einer gewissen Toleranz berechnet, die abhängig vom Abstand 44 der Querstäbe 29 ist, da es aus statischen Gründen sinnvoll ist, die Abstandhalter 4 nicht genau auf die durch 31 und 32 vorgegebenen Positionen zu setzen, sondern auf den nächstgelegenen Kreuzungspunkt zu verschieben.In the specific case, the type of element is dominated by the five longitudinal lines on which the longitudinal reinforcement concentrates and on which the
Anhand dieser Berechnungsmethode ist es möglich, einen Satz im Wesentlichen optimaler Positionen 33, 34 zur Abstützung der Bewehrungskonstruktion 1 in Abhängigkeit der bereitgestellten Daten der Bewehrungskonstruktion 1 zu berechnen, wobei dieser Satz an Positionen 33, 34 eine minimale Anzahl an Abstandhaltern 4 bei einem gleichzeitig tolerierbaren Durchhängeverhalten der Bewehrungskonstruktion 1, welches sich in weiterer Folge auf die Qualität des herzustellenden Betonfertigteils auswirkt, sicherzustellen.By means of this calculation method, it is possible to calculate a set of substantially
In einem dritten Verfahrensschritt 25 werden die Abstandhalter 4 nun an den berechneten Positionen 33 und 34 zur Abstützung der Bewehrungskonstruktion 1 platziert. In einem vierten Verfahrensschritt 26 wird eine entsprechend den Daten gefertigte Bewehrungskonstruktion 1 auf den Abstandhaltern 4 abgelegt. Das Ergebnis dieses dritten und vierten Verfahrensschritts 25 bzw 26 ist schematisch in

Dazu wird die Matte wie in
Diese Berechnung wird für Tragebereiche 5, in denen je ein Abstandhalter 4 angeordnet ist, durchgeführt. Die Aufteilung in die Tragebereiche 5 erfolgt beispielsweise ausgehend von einer Seite der Bewehrungskonstruktion 2. Die Anfangsgröße jedes Tragebereichs 5 ist parametrisierbar. In Abhängigkeit von dem Berechnungsergebnis für die Stäbe eines Tragebereichs 5 wird während der Berechnung die Größe der Tragebereiche 5 iterativ verändert, um möglichst nahe an das vorgegebene Drehmoment-Limit heranzukommen. Die Grenzen 16 jedes Tragebereichs 5 werden einerseits von den Grenzen der Bewehrungskonstruktion 2 außen und innen (Aussparungen für Fenster, Türen oder dergleichen) vorgegeben und andererseits von den berechneten Lasten und den daraus resultierenden Grenzen zu weiteren Tragebereichen 5.This calculation is performed for
Es sei noch darauf hingewiesen, dass bei der Berechnung der Positionen 33, 34 der Abstandhalter 4 auch die maximale Tragfähigkeit der Abstandhalter 4 berücksichtigt wird.It should be noted that in the calculation of the
Es bietet sich an, zur Abstützung der Bewehrungskonstruktionen 1, 2 Abstandhalter 4 zu verwenden mit einer gitterartigen Auflagefläche 40, in der Durchbrüche vorgesehen sind, und mit mehreren von der Auflagefläche 40 abstehenden Stützen 42, die sowohl am äußeren Rand als auch im mittleren Bereich an der Auflagefläche 40 angeordnet sein können, wobei durch die Auflagefläche 40 und die äußeren Stützen 42 ein fiktives Volumen des Abstandhalters 4 definiert ist (vergleiche auch
Auf diese Weise ist es möglich, eine Vielzahl von Abstandhaltern 4 platzsparend zueinander anzuordnen. Die gitterartige Auflagefläche 40 ist im vorliegenden Fall rund ausgebildet. Die Stützen 42 bilden das Maß, welches die Betonüberdeckung definiert. Je nach erforderlicher Betonüberdeckung der Bewehrungskonstruktionen 1, 2 können die Stützen 42 länger oder kürzer sein.In this way it is possible to arrange a plurality of

Um nun den untersten Abstandhalter 4 an einer berechneten Position 33, 34 freizugeben, wird der Stopper 39 radial nach außen bewegt, sodass der Abstandhalter 4 mit der Auskragung 45 nicht mehr auf dem Stopper 39 aufliegt (vgl.
Um die Platzierung der Abstandhalter 4 an den berechneten Positionen 33, 34 im Zuge des dritten Verfahrensschritts 25 zu erleichtern, kann eine Markierungsvorrichtung vorgesehen sein, bei der es sich z.B. um einen Plotter handeln kann, welcher die berechneten Positionen 33, 34 der Abstandhalter 4 auf einer Palette anzeichnet. Alternativ kann die Markierungsvorrichtung auch einen modulierbaren Laser umfassen, mit dem die berechneten Positionen 33, 34 für die Abstandhalter 4 entweder sequentiell nacheinander oder gleichzeitig angezeigt werden. In weiterer Folge kann dann eine Bedienperson die Abstandhalter 4 manuell an den berechneten Positionen 33, 34, welche mittels der Markierungsvorrichtung markiert sind, platzieren.In order to facilitate the placement of the
Alternativ oder ergänzend dazu kann die Platzierung der Abstandhalter 4 an den berechneten Positionen 33, 34 im Zuge des dritten Verfahrensschritts 25 auch mittels eines Verlegeautomatens erfolgen.Alternatively or additionally, the placement of the
Es bietet sich an, einen solchen stationären Verlegeautomaten 6 auf einem Taktplatz einer Palettenumlaufanlage vorzusehen. Dabei werden die Paletten 11 längs oder quer von einem zum nächsten Taktplatz der Palettenumlaufanlage verfahren. Im dargestellten Beispiel erfolgt das Verfahren der Palette 11 in Längsrichtung 33.It is advisable to provide such a stationary
Zum Ablegen von Abstandhaltern 4 an den vorberechneten Positionen 33, 34 sind zwei Platziervorrichtungen 19, welche jeweils eine der vorbeschriebenen Vereinzelungsvorrichtungen 8 aufweisen, vorgesehen. Zur Ansteuerung einer bestimmten Position 33, 34 wird die Palette 11 in Längsrichtung 33 und eine der Platziervorrichtungen 19 in Querrichtung 34 entlang eines Querbalkens 17 bewegt. Dabei ist eine Steuereinheit 20 zur Steuerung der Bewegungen der Platziervorrichtungen 19 vorgesehen. Diese Steuereinheit 20 kann gemäß einer bevorzugten Ausführungsform auch die Bewegung der Palette 11 steuern. Weiterhin kann es sich bei der Steuereinheit 20 auch um die programmgesteuerte elektronische Rechenanlage 3 handeln, welche im Zuge des zweiten Verfahrensschritts 24 die Positionen 33, 34 zur Abstützung der Bewehrungskonstruktion 1, 2 in Abhängigkeit der bereitgestellten Daten der Bewehrungskonstruktion 1, 2 berechnet.For placing
Je nach erforderlicher Leistung kann ein solcher stationärer Verlegeautomat 6 auch mehrere parallel zueinander angeordnete Balken, die quer zur Fahrrichtung der Palette 11 angeordnet sind und an denen eine oder mehrere Platziervorrichtungen19 verfahrbar gelagert sind, vorgesehen sein.Depending on the required power, such a stationary

Anstelle der Drehteller können zum Beispiel auch eine oder mehrere Schubladen verwendet werden.Instead of the turntable, for example, one or more drawers can be used.
Zur Speicherung der Abstandhalterstapel können in der Ladestation 9 Zentrierbolzen 15 vorgesehen sein, die in eine zentrale korrespondierende Öffnung 41 in der Auflagefläche 40 der Abstandhalter 4 (vgl.
Grundsätzlich ist es vorstellbar, dass die Platziervorrichtung 19 einen bestimmten Abstandhalterstapel aufnimmt, einen Teil der Abstandhalter 4 des Stapels verbraucht, d.h. im Zuge des dritten Verfahrensschritts 25 an vorberechneten Positionen 33, 34 platziert, und die nicht verbrauchten Abstandhalter 4 wieder an einer Lagerposition abstellt, um einen anderen Abstandhaltertyp, z.B. mit einer anderen Höhe, aufzunehmen.In principle, it is conceivable that the
