Definitions
- the invention relates to a method for forming a foundation with the preamble features of claim 1. Such a method is known from WO 2007/039008 A1 known.
- Prefabricated buildings with columns or pillars usually have these pillars or pillars supporting foundation.
- the foundation can be constructed, for example, as a single or strip foundation or, if necessary for structural reasons, as a plate or Sohlfundament.
- Another possibility to form a hall is the use of precast concrete parts. These are delivered to the construction site and set up and aligned there on the cleanliness course.
- a disadvantage of the former possibility for creating a foundation is that the described method is particularly time-consuming and therefore requires a precisely coordinated planning of the individual sections.
- the formation of the formwork is associated with a considerable amount of material and the use of additional equipment that complicates the formation of the foundation in addition. The speedy construction of the prefabricated building is therefore difficult to carry out.
- the second possibility ie the use of prefabricated components
- the transport of the prefabricated components to the construction site is particularly cumbersome due to the high weight of the components, since special transport vehicles have to be used here.
- the use of heavy equipment is necessary to arrange the prefabricated components in the appropriate places of the foundation and then align.
- the high Manufacturing and transport costs for prefabricated components also increase the total cost of the building to a significant extent.
- Object of the present invention is therefore to provide a method for forming a foundation for columns or pillars, especially of prefabricated buildings available, which can be created very quickly and easily and is inexpensive to create.
- the foundation basket used in this case for the fast and cost-effective creation of foundations for columns and pillars of prefabricated buildings, and this particular of halls in timber frame construction The static requirements that are placed on such halls in timber frame construction, due to the relatively low weight of the building parts no massive foundations. It often turn out to be foundations as the foundation of choice.
- the foundation basket in this case has a designed as a hoop or frame outer reinforcement.
- this outer reinforcement are in particular welded or screwed reinforcement struts and arranged in the foundation basket, in particular welded receptacle.
- the external reinforcement gives the size of the foundation and is chosen taking into account the static requirements. In this case, the size of the foundation formed can be adjusted to the calculated static requirements by changing the diameter and / or the shape of the hoop or frame.
- the reinforcing bars arranged in the outer reinforcement give additional stability to the foundation basket and the finished foundation and, moreover, prevent the frost or the frame from being deformed when filling the foundation basket with concrete due to the inflow of concrete.
- the reinforcement struts in particular their number and orientation, an adaptation of the foundation to the static load can be performed by the prefabricated building.
- the use proves to be particularly durable in this context of sheet steel to form the hoop or frame.
- the use of a sheet metal or sheet metal frame also offers the opportunity to adjust the size of the foundation basket to the particular required dimensions of the foundation basket in a simple and fast manner.
- the formation of elliptical, oval and polygonal foundation baskets depending on the used Reif or frame.
- the Blechreif or frame is deformed with or without temperature exposure accordingly.
- the formation as well as the adaptation of the foundation basket or especially the outer reinforcement can also be done directly at the site.
- the outer reinforcement is delivered for this purpose in the form of a band or tape sections at the site. The ends of the band or the band sections are then flush or overlapping laid on or superimposed and welded or screwed, which of course also a parallel welding and screwing as well as a riveting of the ends in the formation of the outer reinforcement is possible.
- the reinforcing struts which give the foundation basket further stability, are arranged in a favorable manner crosswise in the outer reinforcement.
- the stability of the foundation basket is increased because the deformation of the outer hoop or the outer reinforcement is prevented in several directions.
- a radial arrangement of the reinforcing struts is conceivable. It is recommended to arrange the reinforcing struts one above the other in several levels in the outer reinforcement.
- the receptacle is designed as a quiver.
- this quiver can after forming the foundation in a simple and fast way, the support or the pillar for which the foundation was made, used and thus the prefabricated building to be built.
- the support or the pillar is designed as a tube, then a pin projecting in the direction of the support or the pillar can be arranged in the quiver in the manner of a bushing. The pin is inserted when inserting the support or the pillar into the quiver in the pipe end and fitted into the support or the pillar.
- the pin can be made substantially cylindrical or tuned to the shape of the support or the pillar.
- the receptacle extends over the entire height of the foundation basket, can project beyond the upper edge of the outer reinforcement or flush with this.
- the receptacle is preferably between the intersecting reinforcing struts of the inner Reinforcement of the foundation basket used and welded to the reinforcing struts at least at their crossing points.
- An even better connection between the receptacle and the reinforcing struts results when the reinforcing struts are arranged in several planes, and in particular substantially horizontally aligned in the outer reinforcement and therefore the receptacle connected to several of the reinforcing struts, in particular welded.
- a clamping or screw connection for arranging the recording in the foundation basket or for connection to the reinforcement struts is possible.
- anchor points are provided on the receptacle, the outer reinforcement and / or the reinforcement struts for the arrangement of a support device for the foundation basket.
- the proposed method ensures a particularly quick and easy formation of a foundation for the columns or pillars, especially for prefabricated buildings.
- the foundation basket initially consists only of the outer, in particular mature or frame-like reinforcement and the reinforcement struts arranged therein and the recording.
- this foundation basket has a particularly low weight and can therefore be delivered in large numbers and particularly easily at the construction site for the prefabricated building or only be manufactured there from individual parts. Due to its low weight, the foundation basket enables installation without the use of heavy equipment.
- the alignment of the foundation baskets before the backfilling with concrete and the formation of the foundation without the use of, for example, cranes is possible.
- the lightweight construction allows for a correction of the position of the finished foundation until shortly before filling the foundation basket with concrete.
- the method according to the invention comprises several steps. First, a foundation basket with formed as a hoop or frame outer reinforcement and arranged in the outer reinforcement reinforcing struts and a centrally arranged in the foundation basket receptacle for the support or the pillar on a clean sheet. After this placement of the foundation basket, its orientation and alignment is done filling the foundation basket with concrete. In this case, the use of in-situ concrete is particularly suitable. The placement and alignment of the foundation basket can be due to the ease of execution of the foundation basket without the aid of heavy equipment, with smaller foundation baskets, for example, manually by one or two workers done. It follows that the final foundation or its position is determined only after filling the foundation baskets with concrete and this particular Ortbeton.
- the foundation baskets which serve to form the foundation, already finished at the construction site and then set up at the locations defined for the foundation position on the cleanliness layer.
- the originally first process step is modified such that first the tires or frames forming the outer reinforcement are brought to the final installation location of the foundation and only then a welding or screwing in of the inner reinforcement, i. H. the reinforcement struts takes place.
- the reinforcing struts After arranging the reinforcing struts ultimately the introduction or the insertion of the recording and the connection with the reinforcement struts or the foundation basket can be done. This type of procedure further increases the flexibility in creating the foundation.
- the method according to the invention also comprises the steps described below. After placing the foundation basket and its orientation, a centering hole is introduced into the cleanliness layer. This hole is located centrally under the foundation, or under the recording. After introduction of the centering hole, a support element is inserted into the receptacle, the one with the Centering bore has aligned through bore. This support element prevents deformation of the recording by the filled into the foundation basket concrete.
- the foundation basket is determined after the insertion of the support element by an anchor pin passing through the support element is inserted through the support member in the center hole in the cleanliness layer. Through the anchor pin a provisional determination of the foundation basket is achieved so that its position can not be changed by the filled concrete. It is advisable to perform an exact positioning, for example by using suitable adjusting means or methods before finally setting the foundation.
- the support element is preferably formed as a block of a solid material, thereby having the internal dimensions of the receptacle.
- the support member can thus be positively inserted into the receptacle and removed after filling the foundation basket and curing of the filling material again from the recording.
- sleeves and in particular threaded sleeves are used in the foundation. This can be done by using the sleeves already shortly after filling the foundation basket with concrete at the corresponding positions in the foundation.
- holes are introduced into the foundation and the sleeves are used in these holes.
- an adjustment device is provided for the support or the pillar. Alignment of the pillars or pillars of the entire building by means of suitable, for example GPS-supported surveying, can take place via this adjusting device.
- the adjusting device has a fundamentally parallel leg, which serves as a surveying aid in the alignment of the columns or pillars and also as a receptacle or holder for adjustment aids, such as washers or the like. It also proves advantageous in this context if the leg has a bore has, on the additional adjustment of the support or the pillar takes place after adjustment on the foundation. This determination can preferably be carried out by connecting the leg to the foundation by screwing or other fixative in a suitable manner.
- a directional brace is used to align the support or the pillar. This runs between the foundation and the pillar.
- the straightening brace is, for example, fixed on the foundation side in the sleeve introduced into the foundation.
- the determination of the brace can be done by screwing into the threaded sleeve.
- Fig. 1 shows a foundation basket 10 in plan view.
- This foundation basket 10 is suitable for forming a foundation 20 (see. Fig. 2 and 3 ) for a support 30 of a prefabricated building, such as a hall in timber frame construction.
- the foundation basket 10 has a cylindrical shape.
- the foundation basket 10 is formed by an outer reinforcement 11, which is formed in the embodiment as a tire made of sheet steel.
- the outer reinforcement 11 predetermines the final formation of the foundation 20.
- the design is not limited to the cylindrical shape. Also possible is the formation of the foundation basket 10 with, for example, prismatic, oval or rectangular outer reinforcement 11. Also fixed by the outer reinforcement 11 is the height of the foundation 20 (cf. Fig. 2 ).
- reinforcing struts 12 are arranged to stabilize the foundation basket 10 and to adapt the foundation 20 to the specifications by the statics of the finished building.
- the reinforcing struts 12 are formed of structural steel and are connected to the outer reinforcement 11, for example, welded in this. In addition to the welding of Reinforcing struts 12 and outer reinforcement 11 also screwing the reinforcing struts 12 in the foundation basket 10 is possible.
- the reinforcing bars 12 not only reinforce the foundation 20, but also prevent deformation of the outer reinforcement 11 of the foundation basket 10 when filling the foundation basket 10 with concrete.
- This backfilling with concrete takes place after setting up the foundation basket 10 on a cleanliness layer (not shown), which represents the lowest layer of the foundation of a prefabricated building.
- the foundation basket 10 is hereby placed directly on the cleanliness layer, then aligned, fixed in position and then filled with concrete. After hardening of the concrete, the further construction of the prefabricated building can take place.
- the outer reinforcement 11 of the foundation basket 10 is left in place.
- the reinforcing struts 12 have a plurality of crossing points 13 and define a centrally located in the foundation basket 10 position of the receptacle 14 for the subsequent arrangement of a support 30.
- the receptacle 14 is inserted between the intersecting reinforcing struts 12 and point-connected thereto.
- the connection between reinforcing struts 12 and receptacle 14 can be done by welding or using clamping screws or clamps.
- an inner supporting element 15 (in FIG Fig. 1 indicated by hatching) used, which prevents the deformation of the receptacle 14 during the filling of the concrete in the foundation basket 10.
- the introduction of a centering hole 16 is first carried out in the cleanliness layer.
- the center hole 16 is centrally provided below the foundation basket 10 and arranged in the foundation basket 10 receptacle 14. After the introduction of the centering hole 16, the insertion of the inner support member 15 takes place in the receptacle 14.
- the inner support member which consists of a solid material, such as wood or plastic, in this case has an aligned with the center hole 16 inner recess 17. Through this inner recess 17, an anchoring pin 18 can be inserted into the center hole 16.
- the anchoring pin 18, which projects through the foundation basket 10 and is fixed in the cleanliness layer, prevents a displacement of the foundation basket 10 in this concrete filling. After the concrete has hardened, the anchoring pin 18 is removed. A Movement of the foundation basket 10 is no longer possible.
- the inner support member 15 can be removed from the receptacle 14.
- a support 30 can be used and aligned. After inserting the support 30 into the receptacle 14 and its orientation, the setting of the support 30 by filling the receptacle 14 with concrete takes place.
- the lower end of the support 30, which is inserted into the receptacle 14, is designed for example as a T or double T-beam and thus leaves enough space for the filler. It is conceivable, of course, the same shape with the receptacle 14 execution of the lower end of the support 30. Thus, a positive insertion of the support 30 made in the receptacle 14.
- the foundation basket 10 With the in the Fig. 1 illustrated foundation basket 10, the simple and rapid formation of a foundation 20 for receiving a support 30 is possible.
- the foundation basket 10, which is lightweight prior to filling with concrete, can be easily positioned and aligned on a clean sheet without the use of a lifting device.
- the formation of the foundation 20 is carried out after aligning and fixing the foundation basket 10 by filling the foundation basket 10 with concrete.

- the reinforcing struts 20 are provided in two layers in the foundation.
- receptacle 14 has already been used in the embodiment, the lower end 31 of a support 30 for a prefabricated building.
- the support 30 consists on the one hand of a wooden post 38, which merges in its fundamental extension in a T-beam 39. This T-beam 39 is inserted into the receptacle 14 and fixed in this by filling with concrete. Before filling the receptacle 14 with concrete, the support 30 is initially aligned.
- the lower end 31 of the support 30 introduced into the receptacle 14 has a straightening angle 32 which is used for the adjustment of the support 30.
- Justierunterlagen 33 can be pushed under the horizontal leg 34 of the directional angle 32.
- the leg 34 additionally has a bore, via which a further determination of the support 30 on the foundation 20, for example by means of screws, bolts or pins can be done.
- the foundation has brackets 19, which are connected to the reinforcing struts 12 in the interior of the foundation basket 10. These brackets 19 served as the foundation basket 10 mounted support device and facilitated the transport and alignment of the foundation basket 10 prior to filling with concrete.
- the bracket 19 can be used as anchor points for an outer lining of the building.
- the shown foundation 20 additionally has sleeves 21, which are arranged in the region of the circumference of the foundation 20. These sleeves 21, which were subsequently introduced into the foundation 20 in the exemplary embodiment, serve to receive screws or to fix additional supporting or aligning struts 22 (cf. Fig. 3 ).
- the arrangement of the sleeves 21 can of course also be done before filling the foundation basket 10 with concrete.
- the sleeves 21 can be connected, for example, with the reinforcing struts 12. Also conceivable is the execution of the sleeves 21 as the entire foundation basket projecting threaded sleeves.
- Fig. 3 also shows a side view of another embodiment of the foundation 20. Also in the embodiment of Fig. 3 the lower end 31 of a support 30 has already been inserted in the foundation 20 or in the receptacle 14 provided therein. For final fixing and alignment of the support 30, a directional brace 22 extending between the support 30 and the top 23 of the foundation 20 has been attached. This straightening bar 22, which has a set screw 24, is used to adjust the support 30 before its final determination. To adjust the support position, the support 30 has a directional angle 32. This straightening angle 32 can be underlaid in the course of adjustment with Justierunterlagen 33 and thus allows the fine alignment of the support 30. Both in the embodiment of Fig. 2 as well as in the embodiment of Fig.
- the receptacle 14 is formed as a quiver.
- This quiver is connected to the reinforcing struts 12 at several points of intersection.
- the reinforcing struts 12 are arranged crosswise in the outer reinforcement 11 of the foundation basket 10 and thus form a grid in the interior of the foundation basket 10.
- a radial arrangement of the reinforcing struts 12 is conceivable.
- the arrangement of the reinforcing struts 12 can be deviated from the orientation of two or more levels.
- the connection of a point 35 at the upper end 36 of the outer reinforcement 11 with a point 35 on the foot 37 of the outer reinforcement 11 by the reinforcing struts 12 conceivable.
- the reinforcement bars 12 are used in addition to the fixation of the receptacle 14 as a holder for a bracket 19, which simplifies the handling or the displacement of the foundation basket 10.
- the connection of sleeves 21 with the reinforcement struts is possible.
- the reinforcing struts 12 cause reinforcement of the formed foundation 20 and also prevent deformation of the foundation basket 10 when filled with concrete.
- the foundation basket 10 is not limited to a single receptacle 14. Rather, it is also possible that a plurality of receptacles 14 are arranged side by side in a foundation basket 10.
- the foundation basket 10 can be sized larger for this purpose according to the static requirements.
- the foundation basket 10 also enables the rapid, simple and inexpensive formation of strip foundations.
- the height of the outer reinforcements 11 indicates the ultimate height of the foundation 20. In adaptation to the static requirements can thus be carried out on a change in the hoop or frame height of the outer reinforcement 11, an enlargement of the foundation 20.
- the foundation baskets 10 may be delivered in parts to the construction site and then connected in place to the foundation basket 10.
- the outer reinforcement can be delivered as a steel strip or steel strip section. The ends of the steel strip or the steel strip section are then first connected, for example, welded, bolted, riveted or possibly also glued.
- the outer reinforcement 11 is then placed on a cleanliness layer at the location of the foundation and the reinforcing struts 12 are then welded or screwed inside the outer reinforcement.
- the receptacle 14 or the receptacle 14 are inserted and possibly also connected to the reinforcing struts 12. Only after the completion of the foundation basket 10 is the backfilling of the foundation basket 10 with concrete and thus the formation of the foundation 20. With the construction site completion of the foundation basket 10 can be reacted flexibly to changes in the plan when creating the prefabricated building.

Description
Die Erfindung betrifft ein Verfahren zur Bildung eines Fundaments mit den oberbegrifflichen Merkmalen des Anspruchs 1. Ein solches verfahren ist aus der
Fertiggebäude mit Stützen oder Pfeilern weisen in der Regel ein diese Stützen oder Pfeiler tragendes Fundament auf. Das Fundament kann dabei beispielsweise als Einzel- oder Streifenfundament oder, wenn aus statischen Gründen notwendig, als Platten- oder Sohlfundament aufgebaut sein.Prefabricated buildings with columns or pillars usually have these pillars or pillars supporting foundation. The foundation can be constructed, for example, as a single or strip foundation or, if necessary for structural reasons, as a plate or Sohlfundament.
Bei der Errichtung von Hallen in Holzrahmenbauweise kommen in der Regel Einzelfundamente für Stützen oder Pfeiler des Gebäudes zum Einsatz. Diese Fundamente werden auf einer Sauberkeitsschicht aufgebaut und sind statisch an die jeweils errechneten Belastungen durch das Fertiggebäude angepasst. Um herkömmliche Einzelfundamente zu errichten, sind zumeist umfangreiche Schalungsaufbauten zu erstellen, in die anschließend eine Bewehrung für das Fundament eingebracht wird. Der Schalungsaufbau wird abschließend mit Beton verfüllt. Nach dem Aushärten wird die Schalung abgebaut und das Gebäude auf dem Fundament errichtet, wie dies z.B. auch in der
Eine weitere Möglichkeit die Gründung einer Halle zu bilden, ist die Verwendung von Fertigbetonteilen. Diese werden an der Baustelle angeliefert und dort auf der Sauberkeitsschicht aufgestellt und ausgerichtet. Nachteilig an der erstgenannten Möglichkeit zur Erstellung eines Fundamentes ist, dass das geschilderte Verfahren besonders zeitaufwändig ist und daher eine exakt abgestimmte Planung der einzelnen Bauabschnitte voraussetzt. Darüber hinaus ist die Bildung der Schalung mit einem nicht unerheblichen Materialaufwand und dem Einsatz zusätzlicher Gerätschaften verbunden, die die Bildung des Fundamentes zusätzlich verkomplizieren. Der zügige Aufbau des Fertiggebäudes ist somit nur schwer durchführbar.Another possibility to form a hall is the use of precast concrete parts. These are delivered to the construction site and set up and aligned there on the cleanliness course. A disadvantage of the former possibility for creating a foundation is that the described method is particularly time-consuming and therefore requires a precisely coordinated planning of the individual sections. In addition, the formation of the formwork is associated with a considerable amount of material and the use of additional equipment that complicates the formation of the foundation in addition. The speedy construction of the prefabricated building is therefore difficult to carry out.
Die zweitgenannte Möglichkeit, d.h. die Verwendung von Fertigbauteilen, erlaubt zwar eine relativ zügige Bildung des Fundaments, der Antransport der Fertigbauteile an die Baustelle gestaltet sich jedoch aufgrund des hohen Gewichts der Bauteile als besonders umständlich, da hier spezielle Transportfahrzeuge verwendet werden müssen. Darüber hinaus ist auf der Baustelle der Einsatz von schwerem Gerät notwendig, um die Fertigbauteile an den entsprechenden Stellen der Gründung anzuordnen und anschließend auszurichten. Die hohen Herstellungs- und Transportkosten für die Fertigbauteile erhöhen zudem die Gesamtkosten für das Gebäude in einem nicht unerheblichen Ausmaß.Although the second possibility, ie the use of prefabricated components, permits a relatively rapid formation of the foundation, the transport of the prefabricated components to the construction site is particularly cumbersome due to the high weight of the components, since special transport vehicles have to be used here. In addition, on the construction site, the use of heavy equipment is necessary to arrange the prefabricated components in the appropriate places of the foundation and then align. The high Manufacturing and transport costs for prefabricated components also increase the total cost of the building to a significant extent.
Aufgabe der vorliegenden Erfindung ist es daher, ein verfahren zur Bildung eines Fundaments für Stützen oder Pfeiler, insbesondere von Fertiggebäuden zur Verfügung zu stellen, das besonders schnell und einfach erstellt werden kann und dabei kostengünstig zu erstellen ist.Object of the present invention is therefore to provide a method for forming a foundation for columns or pillars, especially of prefabricated buildings available, which can be created very quickly and easily and is inexpensive to create.
Diese Aufgabe wird gelöst durch ein Verfahren zur Bildung eines Fundaments gemäß Anspruch 1. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.This object is achieved by a method for forming a foundation according to claim 1. Advantageous developments of the invention are the subject of the dependent claims.
Insbesondere eignet sich der dabei verwendete Fundamentkorb für die schnelle und kostengünstige Erstellung von Fundamenten für Stützen und Pfeiler von Fertiggebäuden, und hierbei besonders von Hallen in Holzrahmenbauweise. Die statischen Anforderungen die an derartige Hallen in Holzrahmenbauweise gestellt werden, verlangen aufgrund des relativ geringen Gewichtes der Gebäudeteile keine massiven Gründungsbauten. Es erweisen sich hier oftmals Einzelfundamente als die Gründung der Wahl.In particular, the foundation basket used in this case for the fast and cost-effective creation of foundations for columns and pillars of prefabricated buildings, and this particular of halls in timber frame construction. The static requirements that are placed on such halls in timber frame construction, due to the relatively low weight of the building parts no massive foundations. It often turn out to be foundations as the foundation of choice.
Der Fundamentkorb weist hierbei eine als Reif oder Rahmen ausgebildete äußere Bewehrung auf. In dieser äußeren Bewehrung befinden sich insbesondere eingeschweißte oder eingeschraubte Bewehrungsstreben sowie eine im Fundamentkorb angeordnete, insbesondere eingeschweißte Aufnahme. In dieser wird das untere Ende der Stütze oder des Pfeilers des fertigen Gebäudes eingesetzt. Die äußere Bewehrung gibt die Größe des Fundamentes und wird unter Berücksichtigung der statischen Anforderungen gewählt. Hierbei kann durch Veränderung des Durchmessers und/oder der Form des Reifes oder Rahmens die Größe des gebildeten Fundamentes auf die errechneten statischen Anforderungen abgestimmt werden. Die in der äußeren Bewehrung angeordneten Bewehrungsstreben verleihen dem Fundamentkorb und dem fertigen Fundament zusätzliche Stabilität und verhindern zudem, dass beim Verfüllen des Fundamentkorbes mit Beton der Reif oder Rahmen aufgrund der einfließenden Betonmenge verformt wird. Durch die Bewehrungsstreben, insbesondere deren Anzahl und Ausrichtung, kann auch eine Anpassung des Fundaments an die statische Belastung durch das Fertiggebäude durchgeführt werden.The foundation basket in this case has a designed as a hoop or frame outer reinforcement. In this outer reinforcement are in particular welded or screwed reinforcement struts and arranged in the foundation basket, in particular welded receptacle. In this the lower end of the column or the pillar of the finished building is used. The external reinforcement gives the size of the foundation and is chosen taking into account the static requirements. In this case, the size of the foundation formed can be adjusted to the calculated static requirements by changing the diameter and / or the shape of the hoop or frame. The reinforcing bars arranged in the outer reinforcement give additional stability to the foundation basket and the finished foundation and, moreover, prevent the frost or the frame from being deformed when filling the foundation basket with concrete due to the inflow of concrete. By the reinforcement struts, in particular their number and orientation, an adaptation of the foundation to the static load can be performed by the prefabricated building.
Als besonders dauerhaft erweist sich in diesem Zusammenhang insbesondere die Verwendung von Stahlblech zur Bildung des Reifes oder Rahmens. Die Verwendung eines Blechreifes bzw. Blechrahmens bietet zusätzlich die Möglichkeit, die Größe des Fundamentkorbes auf die jeweils benötigten Dimensionen des Fundamentkorbes in einfacher und schneller Art und Weise anzupassen.In particular, the use proves to be particularly durable in this context of sheet steel to form the hoop or frame. The use of a sheet metal or sheet metal frame also offers the opportunity to adjust the size of the foundation basket to the particular required dimensions of the foundation basket in a simple and fast manner.
Möglich ist auch die Bildung von elliptischen, ovalen sowie mehreckigen Fundamentkörben in Abhängigkeit von dem verwendeten Reif bzw. Rahmen. Hierzu wird der Blechreif oder Rahmen mit oder ohne Temperaturbeaufschlagung entsprechend verformt. Die Bildung ebenso wie die Anpassung des Fundamentkorbes bzw. besonders der äußeren Bewehrung kann auch erst direkt an der Baustelle erfolgen. Die äußere Bewehrung wird hierzu in Form eines Bandes oder von Bandabschnitten an der Baustelle angeliefert. Die Enden des Bandes bzw. der Bandabschnitte werden anschließend bündig oder überlappend an- bzw. übereinander gelegt und verschweißt oder verschraubt, wobei natürlich auch ein paralleles Verschweißen und Verschrauben ebenso wie ein Vernieten der Enden bei der Bildung der äußeren Bewehrung möglich ist.It is also possible the formation of elliptical, oval and polygonal foundation baskets depending on the used Reif or frame. For this purpose, the Blechreif or frame is deformed with or without temperature exposure accordingly. The formation as well as the adaptation of the foundation basket or especially the outer reinforcement can also be done directly at the site. The outer reinforcement is delivered for this purpose in the form of a band or tape sections at the site. The ends of the band or the band sections are then flush or overlapping laid on or superimposed and welded or screwed, which of course also a parallel welding and screwing as well as a riveting of the ends in the formation of the outer reinforcement is possible.
Die Bewehrungsstreben, die dem Fundamentkorb weitere Stabilität verleihen, sind in günstiger Weise kreuzweise in der äußeren Bewehrung angeordnet. Durch die kreuzweise Anordnung der Bewehrungsstäbe wird die Stabilität des Fundamentkorbes erhöht, da die Verformung des äußeren Reifes bzw. der äußeren Bewehrung in mehrere Richtung unterbunden wird. Neben der kreuzweisen Anordnung der Bewehrungsstreben ist selbstverständlich auch eine strahlenförmige Anordnung der Bewehrungsstreben denkbar. Empfehlenswert ist dabei, die Bewehrungsstreben übereinander in mehreren Ebenen in der äußeren Bewehrung anzuordnen.The reinforcing struts, which give the foundation basket further stability, are arranged in a favorable manner crosswise in the outer reinforcement. By the crosswise arrangement of the reinforcing bars, the stability of the foundation basket is increased because the deformation of the outer hoop or the outer reinforcement is prevented in several directions. In addition to the crosswise arrangement of the reinforcing struts of course, a radial arrangement of the reinforcing struts is conceivable. It is recommended to arrange the reinforcing struts one above the other in several levels in the outer reinforcement.
Als besonders vorteilhaft erweist es sich, wenn die Aufnahme als Köcher ausgebildet ist. In diesem Köcher kann nach dem Bilden des Fundamentes auf einfache und schnelle Art und Weise die Stütze bzw. der Pfeiler, für die das Fundament hergestellt wurde, eingesetzt und somit das Fertiggebäude errichtet werden. Ist die Stütze bzw. der Pfeiler als Rohr ausgebildet, so kann im Köcher nach Art einer Buchse ein in Richtung der Stütze bzw. des Pfeilers aufragender Stift angeordnet sein. Der Stift wird beim Einstecken der Stütze bzw. des Pfeiler in den Köcher in das Rohrende eingeführt und in die Stütze bzw. den Pfeiler eingepasst. Der Stift kann dabei im wesentlichen zylindrisch ausgeführt werden oder auf die Ausformung der Stütze bzw. des Pfeilers abgestimmt werden.It proves to be particularly advantageous if the receptacle is designed as a quiver. In this quiver can after forming the foundation in a simple and fast way, the support or the pillar for which the foundation was made, used and thus the prefabricated building to be built. If the support or the pillar is designed as a tube, then a pin projecting in the direction of the support or the pillar can be arranged in the quiver in the manner of a bushing. The pin is inserted when inserting the support or the pillar into the quiver in the pipe end and fitted into the support or the pillar. The pin can be made substantially cylindrical or tuned to the shape of the support or the pillar.
Bevorzugt erstreckt sich die Aufnahme über die gesamte Höhe des Fundamentkorbes, kann die Oberkante der äußeren Bewehrung überragen oder bündig mit dieser abschließen. Die Aufnahme ist bevorzugt zwischen den sich kreuzenden Bewehrungsstreben der inneren Bewehrung des Fundamentkorbes eingesetzt und mit den Bewehrungsstreben wenigstens an deren Kreuzungspunkten verschweißt. Eine noch bessere Verbindung zwischen der Aufnahme und den Bewehrungsstreben ergibt sich, wenn die Bewehrungsstreben in mehreren Ebenen, und dabei insbesondere im wesentlichen horizontal ausgerichtet in der äußeren Bewehrung angeordnet sind und die Aufnahme daher mit mehreren der Bewehrungsstreben verbunden, insbesondere verschweißt werden kann. Neben dem Verschweißen der Aufnahme mit dem Bewehrungsstreben ist auch die Verwendung einer Klemm- oder Schraubverbindung zur Anordnung der Aufnahme in dem Fundamentkorb bzw. zur Verbindung mit den Bewehrungsstreben möglich.Preferably, the receptacle extends over the entire height of the foundation basket, can project beyond the upper edge of the outer reinforcement or flush with this. The receptacle is preferably between the intersecting reinforcing struts of the inner Reinforcement of the foundation basket used and welded to the reinforcing struts at least at their crossing points. An even better connection between the receptacle and the reinforcing struts results when the reinforcing struts are arranged in several planes, and in particular substantially horizontally aligned in the outer reinforcement and therefore the receptacle connected to several of the reinforcing struts, in particular welded. In addition to the welding of the recording with the reinforcement struts and the use of a clamping or screw connection for arranging the recording in the foundation basket or for connection to the reinforcement struts is possible.
Um eine besonders einfache und schnelle Aufstellung der Fundamentkörbe sowie deren leichte Ausrichtung durchführen zu können, wird als besonders empfehlenswert erachtet, wenn an der Aufnahme, der äußeren Bewehrung und/oder den Bewehrungsstreben Ankerpunkte für die Anordnung einer Tragvorrichtung für den Fundamentkorb vorgesehen sind.In order to carry out a particularly simple and fast installation of the foundation baskets and their easy alignment, it is considered particularly recommendable if anchor points are provided on the receptacle, the outer reinforcement and / or the reinforcement struts for the arrangement of a support device for the foundation basket.
Das vorgeschlagene verfahren gewährleistet eine besonders schnelle und einfache Bildung eines Fundamentes für die Stützen oder Pfeiler, insbesondere für Fertiggebäude. Der Fundamentkorb besteht zunächst nur aus der äußeren, insbesondere reif- oder rahmenartigen Bewehrung sowie den darin angeordneten Bewehrungsstreben und der Aufnahme. Verglichen mit Fertigbauteilen weist dieser Fundamentkorb ein besonders geringes Gewicht auf und kann daher in großer Stückzahl und besonders einfach an der Baustelle für das Fertiggebäude angeliefert oder erst dort aus Einzelteilen gefertigt werden. Aufgrund des geringen Gewichtes ermöglicht der Fundamentkorb eine Aufstellung ohne die Verwendung von schweren Geräten. Daneben ist auch die Ausrichtung der Fundamentkörbe vor den Verfüllen mit Beton und der Bildung des Fundamentes ohne die Verwendung von beispielsweise Kranen möglich. Die leichte Bauweise lässt bis kurz vor dem Verfüllen des Fundamentkorbes mit Beton eine Korrektur der Position des fertigen Fundamentes zu.The proposed method ensures a particularly quick and easy formation of a foundation for the columns or pillars, especially for prefabricated buildings. The foundation basket initially consists only of the outer, in particular mature or frame-like reinforcement and the reinforcement struts arranged therein and the recording. Compared with prefabricated components, this foundation basket has a particularly low weight and can therefore be delivered in large numbers and particularly easily at the construction site for the prefabricated building or only be manufactured there from individual parts. Due to its low weight, the foundation basket enables installation without the use of heavy equipment. In addition, the alignment of the foundation baskets before the backfilling with concrete and the formation of the foundation without the use of, for example, cranes is possible. The lightweight construction allows for a correction of the position of the finished foundation until shortly before filling the foundation basket with concrete.
Als besonders günstig wird angesehen, wenn an der Oberseite des Fundaments Muffen eingesetzt sind. Diese Muffen erlauben die nachträgliche Verschraubung des Stützpfeilers oder der Stütze des Fertiggebäudes oder die Anordnung von Richt- oder Stützstreben an den Stützen oder Pfeilern.Being particularly favorable is considered when at the top of the foundation Muffs are used. These sleeves allow the subsequent screwing of the buttress or the support of the prefabricated building or the arrangement of straightening or support struts on the supports or pillars.
Das erfindungsgemäße Verfahren umfasst dabei mehrere Schritte. Zunächst wird ein Fundamentkorb mit als Reif oder Rahmen ausgebildeter äußerer Bewehrung und in der äußeren Bewehrung angeordneten Bewehrungsstreben sowie einer zentral im Fundamentkorb angeordneten Aufnahme für die Stütze oder den Pfeiler auf eine Sauberkeitsschicht aufgesetzt. Nach diesem Aufsetzen des Fundamentkorbes erfolgt dessen Ausrichtung und nach Ausrichtung das Verfüllen des Fundamentkorbes mit Beton. Hierbei bietet sich insbesondere die Verwendung von Ortbeton an. Das Aufsetzen und Ausrichten des Fundamentkorbes kann aufgrund der leichten Ausführung des Fundamentkorbes ohne die Zuhilfenahme von schwerem Gerät, bei kleineren Fundamentkörben beispielsweise auch händisch durch einen oder zwei Arbeiter, erfolgen. Hieraus ergibt sich, dass das letztendliche Fundament bzw. dessen Position erst nach dem Verfüllen des Fundamentkorbes mit Beton und hierbei insbesondere Ortbeton festgelegt wird. Selbstverständlich ist es möglich, die Fundamentkörbe, die zur Bildung des Fundamentes dienen, bereits fertig hergestellt an der Baustelle anzuliefern und dann an den für die Fundamentposition festgelegten Stellen auf der Sauberkeitsschicht aufzusetzen. Daneben wird es jedoch auch als empfehlenswert angesehen, wenn neben der herstellerseitigen Fertigstellung des Fundamentkorbes eine Bildung der inneren Bewehrung des Fundamentkorbes, d. h. das Einbringen von Bewehrungsstreben und ggf. der Aufnahme in die äußere Bewehrung erst am Verbauungsort erfolgt. Demnach wird der ursprünglich erste Verfahrenschritt dahingehend abgewandelt, dass zunächst die die äußere Bewehrung bildenden Reifen oder Rahmen an den endgültigen Aufstellort des Fundaments gebracht werden und erst dann ein Einschweißen oder Einschrauben der inneren Bewehrung, d. h. der Bewehrungsstreben erfolgt. Nach dem Anordnen der Bewehrungsstreben kann letztlich die Einführung bzw. das Einsetzen der Aufnahme und das Verbinden mit dem Bewehrungsstreben bzw. dem Fundamentkorb erfolgen. Durch diese Art des Vorgehens wird die Flexibilität bei der Erstellung des Fundamentes weiter erhöht.The method according to the invention comprises several steps. First, a foundation basket with formed as a hoop or frame outer reinforcement and arranged in the outer reinforcement reinforcing struts and a centrally arranged in the foundation basket receptacle for the support or the pillar on a clean sheet. After this placement of the foundation basket, its orientation and alignment is done filling the foundation basket with concrete. In this case, the use of in-situ concrete is particularly suitable. The placement and alignment of the foundation basket can be due to the ease of execution of the foundation basket without the aid of heavy equipment, with smaller foundation baskets, for example, manually by one or two workers done. It follows that the final foundation or its position is determined only after filling the foundation baskets with concrete and this particular Ortbeton. Of course, it is possible to deliver the foundation baskets, which serve to form the foundation, already finished at the construction site and then set up at the locations defined for the foundation position on the cleanliness layer. In addition, however, it is also considered to be recommended if, in addition to the manufacturer's completion of the foundation basket formation of the inner reinforcement of the foundation basket, d. H. the introduction of reinforcing struts and possibly the inclusion in the outer reinforcement takes place only at the construction site. Accordingly, the originally first process step is modified such that first the tires or frames forming the outer reinforcement are brought to the final installation location of the foundation and only then a welding or screwing in of the inner reinforcement, i. H. the reinforcement struts takes place. After arranging the reinforcing struts ultimately the introduction or the insertion of the recording and the connection with the reinforcement struts or the foundation basket can be done. This type of procedure further increases the flexibility in creating the foundation.
Das erfindungsgemäße Verfahren umfasst auch die nachfolgend beschriebenen Schritte. Nach dem Aufsetzen des Fundamentkorbes und dessen Ausrichtung wird eine Zentrierbohrung in die Sauberkeitsschicht eingebracht. Diese Bohrung befindet sich zentral unter dem Fundament, bzw. unter der Aufnahme. Nach Einbringen der Zentrierbohrung wird in die Aufnahme ein Stützelement eingesetzt, das eine mit der Zentrierbohrung fluchtende durchgehende Bohrung aufweist. Dieses Stützelement verhindert eine Verformung der Aufnahme durch den in den Fundamentkorb eingefüllten Beton. Der Fundamentkorb wird nach dem Einsetzen des Stützelementes festgelegt, indem ein das Stützelement durchlaufender Verankerungsstift durch das Stützelement in die Zentrierbohrung in der Sauberkeitsschicht eingeführt wird. Durch den Verankerungsstift wird eine vorläufige Festlegung des Fundamentkorbes erreicht, sodass dessen Position durch den eingefüllten Beton nicht mehr verändert werden kann. Es empfiehlt sich eine genaue Positionierung, beispielsweise durch Verwendung geeigneter Justiermittel oder Verfahren vor dem letztendlichen Festlegen des Fundamentes durchzuführen.The method according to the invention also comprises the steps described below. After placing the foundation basket and its orientation, a centering hole is introduced into the cleanliness layer. This hole is located centrally under the foundation, or under the recording. After introduction of the centering hole, a support element is inserted into the receptacle, the one with the Centering bore has aligned through bore. This support element prevents deformation of the recording by the filled into the foundation basket concrete. The foundation basket is determined after the insertion of the support element by an anchor pin passing through the support element is inserted through the support member in the center hole in the cleanliness layer. Through the anchor pin a provisional determination of the foundation basket is achieved so that its position can not be changed by the filled concrete. It is advisable to perform an exact positioning, for example by using suitable adjusting means or methods before finally setting the foundation.
Um eine Verformung der Aufnahme während des Einfüllens des Betons in den Fundamentkorb zu verhindern, ist das Stützelement bevorzugt als Klotz aus einem Vollmaterial ausgebildet und weist dabei die Innendimensionen der Aufnahme auf. Das Stützelement kann somit formschlüssig in die Aufnahme eingesetzt werden und nach Verfüllen des Fundamentkorbes und Aushärten des Füllmaterials wieder aus der Aufnahme entnommen werden.In order to prevent deformation of the receptacle during the filling of the concrete in the foundation basket, the support element is preferably formed as a block of a solid material, thereby having the internal dimensions of the receptacle. The support member can thus be positively inserted into the receptacle and removed after filling the foundation basket and curing of the filling material again from the recording.
Als günstig wird angesehen, wenn nach dem Verfüllen des Fundamentkorbes und nach dem Aushärten des eingefüllten Betons eine Entnahme des Verankerungsstiftes und anschließend des Stützelementes erfolgt. Nach der Entnahme kann in die nun freie Aufnahme das untere Ende einer Stütze oder eines Pfeilers, das beispielsweise als T- oder Doppel-T-Träger ausgebildet sein kann, eingesetzt und das Gebäude, beispielsweise eine Halle in Holzrahmenbauweise errichtet werden. Nach dem Einsetzen der Stütze oder des Pfeilers und dessen Ausrichtung erfolgt die Verfüllung der Aufnahme mit einem Füllmaterial, wobei sich hierbei insbesondere Beton anbietet. Durch die Verfüllung der Aufnahme wird letztendlich die Position und Ausrichtung der Stütze oder des Pfeilers festgelegt. Als vorteilhaft erweist es sich, wenn vor oder nach dem Aushärten des Betons Muffen und hierbei insbesondere Gewindemuffen im Fundament eingesetzt werden. Dies kann dadurch erfolgen, dass die Muffen bereits kurz nach dem Verfüllen des Fundamentkorbes mit Beton an den entsprechenden Positionen im Fundament eingesetzt werden. Daneben ist es selbstverständlich auch möglich, dass Bohrungen in das Fundament eingebracht werden und die Muffen in diese Bohrungen eingesetzt werden. Ebenfalls als günstig wird angesehen, wenn eine Justiervorrichtung für die Stütze oder den Pfeiler vorgesehen ist. Über diese Justiervorrichtung kann eine Ausrichtung der Stützen oder Pfeiler des gesamten Gebäudes durch geeignete, beispielsweise GPSunterstützte Vermessungsverfahren, erfolgen. Eine bevorzugte Weiterbildung des Verfahrens sieht vor, dass die Justiervorrichtung einen fundamentparallel ausgerichteten Schenkel aufweist, der als Vermessungshilfe bei der Ausrichtung der Stützen oder Pfeiler und ferner als Aufnahme oder Halterung für Justierhilfsmittel, beispielsweise Unterlegscheiben oder dgl. dient. Vorteilhaft erweist es sich in diesem Zusammenhang auch, wenn der Schenkel eine Bohrung aufweist, über die nach dem Justieren eine zusätzliche Festlegung der Stütze oder des Pfeilers am Fundament erfolgt. Diese Festlegung kann bevorzugt durch Verbinden des Schenkels mit dem Fundament durch Verschrauben oder sonstige Fixiermittel in geeigneter Weise durchgeführt werden.It is regarded as favorable if, after filling of the foundation basket and after hardening of the filled concrete, a removal of the anchoring pin and subsequently of the supporting element takes place. After removal, the free end of the lower end of a support or a pillar, which may be formed, for example, as a T or double T-beam, used and built the building, for example, a hall in timber frame design. After inserting the support or the pillar and its orientation, the backfilling of the recording is carried out with a filling material, which in particular offers concrete here. The backfilling of the receptacle ultimately determines the position and orientation of the column or pillar. It proves to be advantageous if, before or after the hardening of the concrete, sleeves and in particular threaded sleeves are used in the foundation. This can be done by using the sleeves already shortly after filling the foundation basket with concrete at the corresponding positions in the foundation. In addition, it is of course also possible that holes are introduced into the foundation and the sleeves are used in these holes. Also considered to be favorable when an adjustment device is provided for the support or the pillar. Alignment of the pillars or pillars of the entire building by means of suitable, for example GPS-supported surveying, can take place via this adjusting device. A preferred embodiment of the method provides that the adjusting device has a fundamentally parallel leg, which serves as a surveying aid in the alignment of the columns or pillars and also as a receptacle or holder for adjustment aids, such as washers or the like. It also proves advantageous in this context if the leg has a bore has, on the additional adjustment of the support or the pillar takes place after adjustment on the foundation. This determination can preferably be carried out by connecting the leg to the foundation by screwing or other fixative in a suitable manner.
Eine vorteilhafte Weiterbildung des erfindungsgemäßen Verfahrens sieht vor, dass zur Ausrichtung der Stütze oder des Pfeilers eine Richtstrebe verwendet wird. Diese verläuft zwischen dem Fundament und der Stütze bzw. dem Pfeiler. Die Richtstrebe ist dabei beispielsweise fundamentseitig in der in das Fundament eingebrachten Muffe festlegbar. Die Festlegung der Richtstrebe kann dabei durch Einschrauben in die Gewindemuffe erfolgen.An advantageous development of the method according to the invention provides that a directional brace is used to align the support or the pillar. This runs between the foundation and the pillar. The straightening brace is, for example, fixed on the foundation side in the sleeve introduced into the foundation. The determination of the brace can be done by screwing into the threaded sleeve.

Der Fundamentkorb 10 ist nicht auf eine einzige Aufnahme 14 beschränkt. Vielmehr ist es auch möglich, dass in einem Fundamentkorb 10 mehrere Aufnahmen 14 nebeneinander angeordnet sind. Der Fundamentkorb 10 kann hierfür entsprechend den statischen Anforderungen größer dimensioniert werden. Somit ermöglicht der Fundamentkorb 10 auch die schnelle, einfache und kostengünstige Bildung von Streifenfundamenten. Die Höhe der äußeren Bewehrungen 11 gibt dabei die letztendliche Höhe des Fundamentes 20 vor. In Anpassung an die statischen Anforderungen kann somit über eine Veränderung der Reif- oder Rahmenhöhe der äußeren Bewehrung 11 eine Vergrößerung des Fundamentes 20 durchgeführt werden.The
Die Fundamentkörbe 10 können in Einzelteilen an der Baustelle angeliefert werden und dann an Ort und Stelle zum Fundamentkorb 10 verbunden werden. Hierbei kann die äußere Bewehrung als Stahlband oder Stahlbandabschnitt angeliefert werden. Die Enden des Stahlbandes oder des Stahlbandabschnittes werden dann zunächst verbunden, beispielsweise verschweißt, verschraubt, vernietet oder ggf. auch verklebt. Die äußere Bewehrung 11 wird dann am Ort des Fundamentes auf einer Sauberkeitsschicht aufgelegt und die Bewehrungsstreben 12 werden anschließend im Inneren der äußeren Bewehrung eingeschweißt oder eingeschraubt. An den Kreuzungspunkten 13 der Bewehrungsstreben 12 werden schließlich die Aufnahme 14 bzw. die Aufnahme 14 eingesetzt und ggf. noch mit den Bewehrungsstreben 12 verbunden.
