Description

The invention relates to a reinforcement device for creating a position-specific reinforcement on a structure, in particular on a bored pile head and its geometric fixation, as well as methods for creating position-specific reinforcements and geometric fixation of the bored pile head.

Reinforcements for structures and methods for creating a reinforcement are known in various embodiments from the prior art. In this case, the reinforcement is arranged with respect to the building part to be erected within a building material, in particular concrete. In particular, it is known to connect individual reinforcing elements, in particular reinforcing bars, to a reinforcement with each other and then surrounded within a casing or piping with a flowable building material, in particular in-situ concrete. Alternatively, a pre-formed reinforcement, such as a reinforcement mat or a reinforcement cage is used.

Furthermore, it is customary to produce a building in several sections, so that a projecting from an already completed part of the building structure reinforcement must be integrated into another, to be arranged structural part or connected to the reinforcement.

Since the reinforcement is aligned with respect to the respective component to be reinforced or the casing or casing, it is usually not possible to set up an already completed structural part another, manufactured as prefabricated structural part, since the outstanding from the already completed structural part reinforcement with respect their location in the room is not sufficiently precisely aligned. This problem arises in particular for particularly large or multi-part structures, such as a bridge or a Bohrpfahlstützwänden along railway lines, in which a component of the superstructure is arranged on a plurality of pillars or bored piles, each with protruding reinforcement.

However, this highly limited possibility of using prefabricated parts leads to a dependence of the construction process of construction conditions, a high cost and long construction times and, associated with a long-term disturbance, for example, the surrounding traffic in the field of construction.

The invention is therefore based on the object to provide a reinforcement device and a method to create a reinforcement with a specific, precise position and the component in a particularly simple manner, whereby a particularly cost-effective and fast construction with minor interference with the operation of a complex Building is possible.

The object is achieved by a device according to claim 1 and method according to claim 10. Advantageous developments of the invention are specified in the dependent claims.

The reinforcement device according to the invention for creating a position-specific reinforcement of a building and the associated structural part, in particular with respect to a bored pile head, comprises a filling pipe for filling liquid building material, in particular concrete, and a reinforcing rod fixing device arranged on the filling pipe for a plurality of reinforcing rods, wherein at least one of the reinforcing rod fixing device adjustable alignment element for aligning the on a component of a structure to be reinforced, in particular on a reinforcing cage, is arranged.

In the invention, the inventor has recognized that a precise alignment of the position of the reinforcement of components of a building in relation to the entire structure in a particularly simple manner allows the use of prefabricated components and thus leads to a significant reduction in the duration of the construction project and to a significant cost savings , In particular, the invention enables the construction of structures with respect to traffic routes or means, in particular bridges and bored pile support walls along railway lines, with significantly reduced intervention times in the traffic.

In this case, the invention is based on the finding that the entire reinforcement of a building or a part of a building can not be easily aligned precisely with respect to its location in absolute space, but the arrangement of individual reinforcing elements at a junction of two parts of a building readily are precisely aligned. In particular, an alignment of a plurality of reinforcing bars at one end of a bored pile is readily possible, regardless of the reinforcement of the bored pile formed by a reinforcement cage.

Furthermore, the inventor has recognized that it is advantageous if two parts of a structure, in particular a bored pile, which are to be arranged next to one another, already have a particularly position-determined planar surface, which is aligned with the part of the building to be arranged thereon.

Finally, the inventor has recognized that a support of the reinforcement device relative to a component of the structure to be reinforced is advantageous over a support on the ground surrounding the structure, as an aboveground support, especially in track or bridge construction, due to the often low, available Area on the ground is possible only to a very limited extent, and moreover disadvantageous vibrations are conducted from the surface of the environment in the structure to be reinforced, which then lead to a deterioration of the building result.

The method according to the invention for producing a position-determined reinforcement, in particular on a bored pile head, comprises initially arranging a reinforcement device on a component of a structure to be reinforced, in particular on a reinforcement cage for producing a bored pile, followed by filling in liquid construction material, in particular concrete or mortar. preferably up to at least one contact surface of the reinforcement device, particularly preferably up to half of a reinforcement rod fixing device of the reinforcement device.

In this case, the lower reinforcing rod fixing element 5 is welded to the filling tube 2, while the upper reinforcing rod fixing element 6 is connected via a screw 27 to the filling tube 2.

Both the lower and the upper reinforcing bar fixing element 5, 6 has numerous receiving openings 12 for reinforcing bars 22, wherein the receiving openings 12 of the lower and the upper reinforcing bar fixing elements 5, 6 along a direction parallel to the filling tube 2 are arranged to cover each other ( Fig. 1a, b ). In each case, two corresponding receiving openings 12a, b are connected by a protective casing element 13, which is mounted both over the entire lower space 14 and the upper reinforcing bar fixing element 5, 6.

The receiving openings 12 are arranged along a grid in the reinforcing bar fixing device 3 ( Fig. 7a, b ), wherein significantly more receiving openings 12 may be provided as reinforcing bars 22 are needed in the structure to be reinforced 21 to 10 by only partially equipping the receiving openings 12 with reinforcing bars 22 to create different desired arrangements can. In addition, the arrangement of the receiving openings 12 can be adjusted within the reinforcing bar fixing device 3 in particular to the dimensions of a transverse reinforcement 37 ( Fig. 8 ), in particular if the position-determined reinforcement of a component created by means of the reinforcement device 1 is to be provided for the attachment of a further component or for the use of a prefabricated component.

In each case offset by 90 ° along the circumference of the cylindrical reinforcing rod fixing device 3, four length-adjustable alignment elements 4a, b, c, d are arranged in the intermediate space 14 between the upper reinforcing bar fixing element 6 and the lower reinforcing bar fixing element 5 such that a support element 7 of the alignment element 4 is replaced by a Recess 8 can be moved linearly beyond the lower reinforcing rod fixing element 5 in order to be able to support the reinforcing device 1 ( Fig. 1a, b ). In this case, the support element 7 is movable relative to the reinforcing rod fixing device 3 parallel to a central longitudinal axis of the filling tube and to an axis through the centers of two corresponding receiving openings 12a, b or to a central longitudinal axis of the tube formed by two corresponding receiving openings 12a, b and the associated protective sleeve member 13.

In particular, the support elements 7 of the alignment elements 4 are designed such that they can be supported on the upper side of a reinforcing cage 19 for reinforcement of a bored pile or a support ring 19 arranged on the reinforcing cage 29 ( Fig. 2a, b ).

The alignment element 4 comprises in a first embodiment a rotatably disposed within an opening 9 of the upper reinforcing bar fixing element 6 and secured against displacement in the longitudinal axis direction control rod 10. The Abstützeleelement 7 of this embodiment is arranged against rotation with respect to the lower reinforcing bar fixing element 5 ( Fig. 5a, b ). The anti-rotation of the support member 7 is achieved on the one hand, that the support element is guided on all sides fitting within the recess 8 of the lower reinforcing rod fixing element 5. In addition, the support element 7 is also guided fittingly on a housing 31 arranged and welded between the lower reinforcing bar fixing element 5 and the upper reinforcing bar fixing element 6. On the one hand rotation of the support element 7 in the intermediate space 14 is prevented by the housing, and on the other hand penetration of foreign bodies, in particular of liquid or solid building material 23 is prevented, which could lead to a functional impairment of the alignment element 4 ( Fig. 5a, b ).

An adjustability of the support element 7 is achieved in that the adjusting rod 10 at one end has an external thread 11a, which cooperates with an internal thread 11b of the support member 7, and the other end is fixed to the upper reinforcing rod fixing element 6, that a displacement along the central longitudinal axis of the control rod 10 opposite the upper reinforcing rod fixing element 6 is excluded. For this purpose, the control rod 10 has a fixed fixing ring 32 which is supported against the surface of the upper reinforcing rod fixing element 6 facing the lower reinforcing rod fixing element 5. Also on the opposite surface of the upper reinforcing bar fixing element 6, a fixing element 33 is fixedly arranged on the adjusting rod 10 in order to prevent movement of the adjusting rod 10 along its central longitudinal axis. Finally, at one end of the control rod 10 on the side facing away from the lower reinforcing rod fixing member 5 side of the upper reinforcing rod fixing member 6, an actuator 34 for rotation of the control rod 10 by means of a hex wrench arranged ( Fig. 5a, b ).

In a second embodiment of the alignment element 4, the support element 7 is fixedly connected to the control rod 10, which is displaceably guided along its central longitudinal axis through an opening 9 of the upper reinforcing rod fixing element 6. Furthermore, in the region of the opening 9 at the lower reinforcing bar fixing member 5 opposite surface of the upper reinforcing bar fixing member 6, a clamping device 35 arranged for fixing the control rod 10. At an end opposite the supporting element 7, the adjusting rod 10 has an adjusting element 36, on which the alignment element 4 can be adjusted by means of a tool ( Fig. 6a, b ).

At the opposite end of the reinforcing rod fixing device 3 end of the filling tube 2, a support device 18 is fixed. In this case, the support device 18 is formed from at least three supports 25, which are connected via connecting elements 39 by means of a screw 40 with a central part 26 ( Fig. 1 such as Fig. 9a, b ). The middle part 26 has a receiving ring 42, which can be screwed over the filling tube 2 screwed with this. The individual supports 25 are adjustable in length in the direction of the central longitudinal axis of the filling tube 2 by means of an adjusting thread 41. Furthermore, the central part 26 has recesses 38 for pushing through reinforcing bars 22, wherein the position of the center of the recesses 38 along the direction of the central longitudinal axis of the filling tube 2 corresponds to the position of the receiving openings 12 on the reinforcing rod fixing device 3.

For producing a structure, in particular a bored pile, with a defined surface structure, a cylindrical bordering body 24, in particular with toothing, can be fixed to the underside of the reinforcing rod fixing device 3, in particular in the area of a contact surface 16 to the bored pile to be reinforced ( Fig. 3 ). In addition, the enclosure body 24 can also be left on this for further reinforcement of the bored pile head. Alternatively, an enclosing body 24 which can be arranged on the reinforcing rod fixing device 3 can also have a different shape or a different cross section. For example, this can be designed as a rectangular box, in particular with toothing ( Fig. 4a, b ). Furthermore, in order to increase the carrying capacity, one or more support rods 30 may be arranged inside the enclosure body 24. When using a bordering body 24, the support elements 7 of the alignment elements 4 can be designed such that they extend to a side of the bordering body 24 facing away from the reinforcing bar fixing device 3, so that the support of the reinforcing device 1 takes place on this side of the bordering body 24 (FIG. Fig. 4a ).

In the method according to the invention an open steel pipe is first drilled as a casing 43 in the bottom 45, so that as well as the removal of the earth deep inside the casing 43, a borehole 50 is formed. Subsequently, a reinforcement cage 19 is lowered into the borehole until an upper edge of the reinforcing cage 19 at the height of the borehole 50 surrounding bottom 45 and the upper end of the casing 43 can be secured against further lowering, for example by means of steel pipes 44.

Subsequently, a reinforcement device 1 is attached to a holding adapter 46, which is arranged on a filling tube 2 of the reinforcement device 1, by means of a crane or a drill to the upper, protruding from the bottom 45 and the tubing 43 end of the reinforcing cage 19 and with the Reinforcement cage 19 connected or stored ( Fig. 10 ). The connection can be made in advance, such as in the manufacture of the reinforcement cage 19.

Subsequently, the reinforcement device 1 including the attached reinforcement cage 19 is lowered into the casing 43 until the reinforcement cage has reached the intended settling depth. The reinforcing rod fixing device 3 of the reinforcement device 1 is then partially or completely in the casing 43 and at the same time the filling tube 2 is still to protrude ( Fig. 11 ).

Over the filling tube 2 is subsequently filled so long concrete 23 until the tubing 43 is filled to about half of the reinforcing rod fixing device 3, wherein the leaked from the filling tube 2 concrete 23 penetrates through concrete inlet openings 47 at the bottom of the reinforcing rod fixing device 3 in this.

In order to prevent inadmissible displacement of the reinforcement device 1 in a direction radial to a longitudinal axis direction of the casing 43 after detachment of the reinforcement device 1 from the reinforcement cage 19, at least four reinforcing bars 22 are inserted into a respective receiving opening 12 of the reinforcing rod fixing device 3, wherein in each case at the reinforcing bars 22nd a securing rod 47 is fixed such that the reinforcing bar 22 can slide into the receiving opening 12 only to the locking bar 47. The length of the reinforcing bars 22 is chosen such that these protrude statically deep enough through the reinforcing rod fixing device 3 into the reinforcing cage 19 ( Fig. 12a, b ).

In order to allow a subsequent orientation of the reinforcement device 1 for generating a position-determined reinforcement 20, the connection of the reinforcement device 1 is released with respect to the reinforcement cage 19, wherein the reinforcement device 1 is held on the holding adapter 46 arranged thereon by means of the crane or the drilling device in its position , The reinforcement device 1 can now be measured, in particular with regard to the desired position of the later produced reinforcement 22, wherein the reinforcement device 1 can be rotated within the casing 19 to a desired position and on the other also in their height and inclination, in particular also be adapted to the reinforcement cage 19 ( Fig. 12b, c ). If the reinforcement device 1 is in a desired position, then the reinforcement device 1 is fixed by means of an adjustment of the alignment elements 4, wherein the alignment elements 4 rest on a support ring 29 of the reinforcement cage 19. If necessary, an additional support of the reinforcement device 1 with respect to the bottom 45 surrounding the borehole 50 can also take place by means of a support device 18 (FIG. Fig. 1a ). The support 18 is usually used when the reinforcement cage 19 can not be discontinued down to the foundation base of the bored pile. The alignment elements 4 are then usually not used ( Fig. 9a, b ).

Subsequently, reinforcing bars 22 are provided in further receiving openings 12 of the reinforcing bar fixing device 3 of the fixed reinforcing device 1 with securing bars 47, so that they penetrate into the still liquid concrete 23 ( Fig. 13a, b ). When all the reinforcing bars 22 are in the intended positions, the reinforcing device 1 can be secured against further change in position by filling the remaining cavities, ie, the casing 43 at least as far as with granular building material 51 (such as gravel, grit, ash, Granualt) is filled until the reinforcing rod fixing device 1 completely granular building material 51 filled and / or covered.

The thus fixed reinforcement device 1 can now be solved by the crane or the drill. In addition, however, it is often also possible to separate the reinforcement device 1 before the introduction of further reinforcing rods 22 already from the crane.
After sufficient hardening of the concrete 23, the securing rods are removed from the reinforcing bars 22 or the reinforcing bars 22 separated accordingly, so that the reinforcement device 1 can be pulled out, inter alia, by means of the holding adapter 46, wherein the separation of the reinforcing device 1 from the cast, sufficiently hardened Concrete 23 is facilitated by means of a arranged on the bottom 16 of the reinforcing rod fixing device 3 separating film 15. After the extraction of the reinforcement device 1, the bored pile 21 produced in this way has plane surfaces as well as a defined designed and aligned reinforcement 22. Further advantageously, the granular building material 51, the uneven surface of the cast concrete 23 and optionally unsustainable cast-in concrete 23, which at the pouring of the concrete 23 above, referred to as concrete overflow 49, remains in the reinforcement device 1 and is shared with the formed from Drill pile 21 removed. The concrete overflow 49 lies above the lower reinforcement rod fixing element 5 (FIG. Fig. 13a , 15a).

Finally, the tubing 43 is pulled out by means of the crane or the drill and depending on the hardened state of the concrete with the additional use of heavy construction equipment. At the earliest, the pulling of the casing 43 after sufficient hardening of the concrete 23 can be done to a humid condition.

By means of the method according to the invention, a layer-defined reinforcement 20 is obtained, so that a transverse reinforcement 37 can be easily applied to the reinforcement 20 of a plurality of bored piles 21 without any problems. The reinforcement 20 is arranged in each case in intermediate spaces of the transverse reinforcement 37 and consequently also the transverse reinforcement 37 in particular can be arranged precisely ( Fig. 14 ). Alternatively, the position-determined reinforcement 20 also allows the use of finished parts for further completion of the structure 21.
