Description

The present invention relates to a positioning element for positioning an installation part on a metal formwork in a concrete segment to be cast by means of a magnet arrangement.

Nowadays, concrete segments of structures, such as a concrete wall, a concrete floor or a concrete ceiling, are already manufactured with corresponding cast-in components for further assembly. The built-in parts can be, for example, installation boxes for attaching electrical switches, sockets, lamps, devices or for branches that are concreted into the building at the designated locations. Also known are built-in parts in the form of anchoring elements, for example for connecting the respective concrete segments to one another, or built-in parts in the form of wall and ceiling transition pieces for fastening plastic pipes for inserting installation lines into a concrete segment or for transferring installation lines from one concrete segment to an adjacent concrete segment.

These built-in parts are installed in a concrete segment by fixing the built-in parts relative to the (metal) formwork before concreting the concrete segment, with the built-in part being cast in during the concrete casting. As a rule, the built-in part is temporarily attached to the formwork of the concrete segment to be cast, for example by gluing or magnetically attaching it. Depending on the built-in part, additional positioning elements are required, which position the built-in part relative to the magnet arrangement and fasten the built-in part to the formwork.

A problem with the use of such positioning elements is that a further step for removing the positioning element may be necessary in addition to removing the magnet arrangement. A quick and cost-effective removal of the generally reusable magnet arrangement from the metal formwork and/or the positioning element after a concrete segment has been cast is also difficult.

Another existing problem is that the built-in part is usually difficult to align with the formwork so that it assumes a predetermined and defined position and, if necessary, orientation. However, this is particularly advantageous with regard to automated processes.

Another existing problem is that the size of the built-in parts can vary depending on the individual application and therefore cannot easily be used with the same magnet arrangement.

It is the object of the present invention to further develop the prior art with regard to positioning elements. Advantageously, at least one of the aforementioned problems should be reduced or eliminated.

The problem is solved in a general manner through the subject matter of the independent patent claims. Further advantageous refinements result from the dependent patent claims as well as the following description and the figures.

The present invention relates to a positioning element for positioning an installation part in a concrete segment to be cast by means of a magnet arrangement. The built-in part is generally intended to remain at least partially in the cast concrete segment - especially in designated places. The built-in part can be used to assemble the concrete segment and/or to install electrical installations in the concrete segment. Preferably, however, the installation part described below is an anchoring element. The anchoring element can be used to (later) attach additional mounting elements. The assembly elements can, for example, be used to connect the respective concrete segments (such as a concrete wall, a concrete floor or a concrete ceiling) to one another or to attach further elements (e.g. furniture, partition walls, etc.) to the concrete segment.

The positioning element according to the invention comprises a base and a circumferential side wall, which together surround a first receiving space, and a receiving opening opposite the base in relation to the first receiving space, via which the first receiving space is accessible. The floor can merge into the side wall. The first receiving space is used to accommodate a magnet of the magnet arrangement. The magnet is used to temporarily attach the positioning element to the metal formwork of the concrete segment to be cast. A tubular socket projects further in an axial direction from a rear side of the base and surrounds a second receiving space for a pin of the magnet arrangement. The connector also serves so that the built-in part can be plugged into it, respectively the connector can be plugged into a mounting opening in the built-in part. The pin of the magnet arrangement serves to attach the magnet to the positioning element. The second recording room can be open at the back. The nozzle advantageously projects from the floor coaxially to the side wall of the positioning element. The positioning element can, for example, be designed to be rotationally symmetrical about a central axis. The central axis therefore extends in the axial direction. The second receiving space is accessible through an opening in the floor from the first receiving space (ie from a front side opposite the rear). In the context of this application, the front is to be understood as facing the metal formwork in the later, installed/cast state. Consequently, the back faces away from the metal formwork.

At least one radially deformable tongue for holding the pin is also arranged in a wall of the tubular socket. Advantageously, the at least one tongue therefore has a first (outer) contact surface for the contact of the positioning element with the built-in part in the inserted state of the built-in part on the socket and a second (inner) contact surface for the contact opposite the first contact surface in relation to the wall of the socket with the tenon. The tongue extends from a proximal to a distal end, in particular in the axial direction. Viewed from the axial direction, the tongue can be arranged essentially within the contour of the nozzle. For example, the tongue (in the undeformed state) can be arranged essentially within the contour of the wall of the nozzle, so that, if present, only the elevation and/or the support element, as described further below, protrude beyond the contour of the wall. For good application of force, the distal end of the tongue advantageously points in the direction of the first receiving space. However, it is also conceivable that the distal end points away from the first receiving space or that the at least one tongue extends in the direction surrounding the nozzle. A rotationally symmetrical design of the at least one tongue (around the central axis) is also conceivable. So that the at least one tongue can be deformed radially as well as possible, it is at least partially surrounded by a recess extending in the radial direction through the wall. The at least one tongue is advantageously formed integrally with the wall of the nozzle. In this case, the tongue merges into the wall at the proximal end of the nozzle. The recess can therefore surround the tongue in a U-shape, in particular from the proximal end.

Depending on the application, the at least one tongue can have an elevation which protrudes into the second receiving space. If an elevation is present, the previously described second (inner) contact surface can be arranged at least partially on the elevation. The elevation protrudes from an inside of the nozzle, which can also represent an inside of the tongue that points towards the second receiving space. The survey can serve to lock the positioning element with the magnet arrangement, as described in more detail below. In other words, the elevation can be designed in such a way that it locks the positioning element with the magnet arrangement, in particular when the built-in part is plugged in. For locking, a thickening arranged on the pin can interact with the tongue, in particular the elevation of the tongue. The assessment is advantageously arranged at a distal end of the tongue and/or the thickening is advantageously arranged at an end of the pin facing away from the magnet. The elevation of the at least one tongue can thus engage between the thickening of the pin and a base of the pin. The pin is attached to the base of the magnet. The thickening of the pin can be cylindrical or spherical. When interacting with the elevation, the thickening forms an undercut in the axial direction (in the locked state of the at least one tongue). This undercut can be solved by deforming the tongue in a radial direction outwards. However, when the built-in part is plugged onto the socket of the positioning element, the at least one tongue cannot be deformed outwardly or can only be deformed to a limited extent, so that the magnet arrangement is locked with the positioning element, or the undercut is prevented from dissolving in the axial direction.

If a magnetic force is applied to the magnet arrangement in the axial direction in the inserted state of the built-in part on the socket of the positioning element, the positioning element detaches from the built-in part, while the magnet arrangement remains locked to the positioning element. This speeds up and simplifies the removal of the magnet arrangement and the positioning element, since they can be removed together and in one step.

In the plugged-in state of the built-in part onto the socket of the positioning element, there is an effective connection between the built-in part and the positioning element first force is less than a second force that effectively connects the positioning element to the magnet arrangement. This is because the operative connection of the built-in part with the positioning element (ie the first force) in this case is based solely on frictional engagement (or the first force is merely a frictional force). On the other hand, the operative connection of the magnet arrangement with the positioning element (ie the second force) can be based on a positive connection in addition to a frictional connection. The positive connection can be formed by the undercut in the axial direction. A larger second force has the advantage that when the cast magnet segment is removed from the formwork, due to the magnetic force acting on the magnet of the magnet arrangement in the axial direction, the magnet arrangement remains on the metal formwork together with the positioning element, while the cast-in part remains in the concrete segment. In other words, the at least one tongue can be designed in such a way that it forms an undercut with the pin in the axial direction when the built-in part is plugged onto the socket.

In order to limit the radial deformation of the tongues outwards when the built-in part is plugged in, the at least one tongue can have a support element on the outside for supporting the tongue in the radial direction against the built-in part. If a support element is present, the previously described first (outer) contact surface can be arranged at least in some areas on the support element. The support element can also be designed in such a way that this only allows limited or even prevents deformation of the at least one tongue outwards when the built-in part is plugged onto the socket. Depending on the height of the respective support element (measured in the radial direction from the outside of the Socket away), the at least one tongue can be held in the undeformed position in the attached state of the built-in part, or can even be deformed radially further inwards by contact with the built-in part, so that the undercut between the tongue and the pin and / or the frictional force between the tongue and the tenon is further strengthened.

In order to center the built-in part plugged onto the nozzle, several centering elements can also be arranged on the outside of the nozzle. One of the several centering elements can, for example, be a centering collar running around the outer surface of the nozzle for centering the built-in part plugged onto the nozzle. The centering collar is preferably arranged at a proximal end of the nozzle, at which the nozzle is attached to the floor. The centering collar and the at least one tongue can be arranged at different positions in the axial direction on the nozzle. Alternatively or additionally, there may be several centering elements distributed around the circumference of the nozzle in the circumferential direction (e.g. in the form of ribs extending in the axial direction). These are preferably arranged in the axial direction and next to the at least one tongue. To lock the magnet arrangement with the positioning element, the support element described above can also protrude in the radial direction from the connector to the same distance as the centering elements (in the undeformed state of the at least one tongue).

For a clean alignment of the magnet arrangement to the positioning element, the connector advantageously has at least one rib projecting into the second receiving space for positioning and in particular centering the pin on. It is advisable here if the rib projects radially into the second receiving space essentially to the same extent as the elevation on the tongue (in the undeformed state of the at least one tongue).

For good alignment of the built-in part, the base advantageously has a contact surface on the back for a front side of the built-in part. A seal for sealing the built-in part against the positioning element when pouring concrete can also be present on the contact surface. The seal can be designed in a ring shape and arranged around the nozzle.

Depending on the application, the side wall can have a cone-shaped outside. This tapers advantageously towards the nozzle. The conical design enables the positioning element to be easily formed from the (later) cast concrete segment. In return, it is advisable for an inside of the side wall, which delimits the first receiving space, to extend essentially in the axial direction. In this way, the magnet is better held in the first receiving space on the circumference. Consequently, the sidewall may have a triangular or V-shaped cross section. Depending on the application, a circumferential groove that is open to a front side of the positioning element can also be arranged between the inside and outside in the side wall. A (further) seal for sealing the positioning device against the metal formwork can be arranged in the groove. The additional seal can thus protect the magnet arrangement from contact with concrete. For example, a soft-elastic material is suitable for the respective seals.

A suitable magnet arrangement can have various shapes. The magnet can have a disk-shaped configuration with two cover surfaces that are parallel to each other and a lateral surface that extends and runs around between the cover surfaces, with one of the cover surfaces being intended to rest on the metal formwork. The magnet can therefore in particular have a substantially circular disk-shaped shape. An axis running through the center of the cover surfaces, which typically extends perpendicular to the cover surfaces, is referred to as the central axis of the magnet arrangement. In a mounted state of the magnet arrangement on the positioning element, the central axis of the magnet arrangement advantageously overlaps the central axis of the positioning element. The preferably non-magnetic pin can protrude centrally from one of the cover surfaces. The magnet is advantageously arranged concentrically to the pin. In one embodiment, the pin can protrude from the rear cover surface. For example, this can be screwed into the magnet or permanently attached in another way, for example by pressing and/or gluing. Furthermore, the pin can be formed integrally or in one piece with the magnet arrangement. Furthermore, the pin or its thickening can be designed to be conical or conical in at least some areas relative to the central axis of the magnet arrangement. The described embodiments of the magnet arrangement also reveal correspondingly designed versions of the positioning element for the operative connection with the positioning element according to the invention and vice versa.

Since the magnet is generally reusable, the size of the mounting opening and/or design of the built-in part changes depending on the application can, it makes sense to provide a set of different positioning elements. A set of different positioning elements can include several positioning elements, which are designed to be inserted into mounting openings of built-in parts with different diameters. In order to still work together optimally with a magnet arrangement of the same design, the respective positioning elements can differ in their design of the nozzle (for example due to different outer diameters of the nozzle and/or different heights of the support elements and/or different heights of the centering elements).

Furthermore, a positioning device can be provided which comprises at least one positioning element (e.g. a positioning element or a set of different, alternative positioning elements) according to one of the previously described variants and a magnet arrangement (with a magnet and a pin arranged on the back of the magnet). Here, the magnet can be accommodated in the first receiving space of the positioning element and the pin can be accommodated at least partially in the second receiving space of the positioning element. The built-in part for casting into a concrete segment can be plugged into the socket of the positioning element. The built-in part is advantageously an anchoring element, as described above.

An installation part in the form of an anchoring element generally has a mounting opening arranged in a main body, which is open (ie accessible) at the front and closed at the rear. When the anchoring element is mounted on the positioning element, the mounting opening extends in the axial direction of the positioning element. During the When pouring concrete, the assembly opening (front) is closed by the positioning element onto which the anchoring element is inserted. This means that no concrete penetrates into the mounting opening in the anchoring element. After pouring concrete and removing the positioning element, the mounting opening can serve to accommodate further mounting elements, such as screws, pins or bolts. These can be used, for example, to connect a concrete segment to another concrete segment or to attach further elements (e.g. furniture, partition walls, etc.) to the concrete segment. For this purpose, the mounting opening can have an internal thread at least in some areas. Since large forces can act on the mounting elements and, conversely, on the cast-in anchoring element, it is advisable if the anchoring element has a plate-shaped area which protrudes laterally from the main body and serves to create a (comparatively large-area) undercut in the axial direction to form poured concrete. The plate-shaped area thus reduces the risk that the anchoring element breaks out of the cast concrete segment, especially when there are large forces applied to the anchoring element. In addition, the anchoring element can also have stiffening ribs. These advantageously extend from the plate-shaped area in the axial direction and towards the front and/or back of the anchoring element. The described embodiments of the anchoring element also reveal correspondingly designed versions of the positioning element for the operative connection with the positioning element according to the invention and vice versa.

Figure 1 and Figure 2 each show a positioning device 5 for an installed part 3 in the form of an anchoring element. The positioning device 5 comprises a positioning element 1 and a magnet arrangement 2 which can be operatively connected to the positioning element 1 and comprises a magnet 15 and a pin 14 for fastening the magnet 15 to the positioning element 1.

The magnet 15 has a disk-shaped design with a front and a rear cover surface 31, 32 and a circumferential surface extending between the cover surfaces 31, 32. The front cover surface 31 serves to rest and magnetically fasten the magnet arrangement 2 to a metal formwork. The pin 14 protrudes from the rear cover surface 32 for operative connection with the positioning element 1. The pin 14 has a thickening 30 at an end facing away from the magnet 15.

The positioning element 1 establishes an operative connection between the magnet arrangement 2 and the built-in part 3. For this purpose, the positioning element 1 comprises a base 6 and a circumferential side wall 7 that merges into it, which together surround a first receiving space 9 for receiving the magnet 15 of the magnet arrangement 2. Opposite the bottom 6 is a receiving opening 11 through which the first receiving space 9 is accessible and the magnet 15 can be inserted into it. A tubular socket 8 projects from a back side 17 of the base 6 in an axial direction and surrounds a second receiving space 10 for holding the pin 14 of the magnet arrangement 2. Opposite the back 17 is a front side 16 of the positioning element 1, which serves to rest on the metal formwork. The second receiving space 10 is accessible from the first receiving space 9 through an opening 12 in the floor 6, so that the magnet arrangement 2 can be introduced into the first and second receiving spaces 9, 10 at the front.

In Figure 1 The built-in part 3 is also shown in the form of the anchoring element. The anchoring element comprises a main body 33 with a mounting opening 35 extending in the axial direction. The anchoring element 3 can, as shown, have a plate-shaped region 34 which protrudes laterally from the main body 33 in order to form an undercut in the axial direction with the poured concrete. The plate-shaped area 34 thus reduces the risk that the anchoring element 3 breaks out of the cast concrete segment 4. Furthermore, the anchoring element 3 also has stiffening ribs 36, which extend from the plate-shaped area 34 in the axial direction to a front side of the anchoring element 3 and support the force distribution on the plate-shaped area 34. It can also be seen that the anchoring element 3 is closed on a back side of the anchoring element 3, so that no concrete can penetrate into the assembly opening 35.

As in Figure 1 as well as in the Figures 3 to 5 As can be seen, in the case shown, two oppositely arranged, radially deformable tongues 18 are formed in the wall 13 of the socket 8 for holding the pin 14. However, a different number or design of the tongues 14 is also possible. For a good introduction of force, the distal end 21 of the respective tongues 18 points in the direction of the first receiving space 9. Furthermore, the tongues 18 are partially surrounded by a recess 22 which extends in the radial direction through the wall 13. At a proximal end 20, the tongue 18 merges into the wall 13. When the pin 14 is inserted into the socket 8, an inwardly facing elevation 19 arranged on an inside 23 of the tongue 18 comes into contact with the thickening 30 of the pin 14 and the tongues 18 become radially outward when the pin 14 is inserted deeper deformed. If the pin 14 is inserted far enough and the thickening of the pin 14 reaches behind the elevation 19 in the axial direction, the tongues 18 snap back and the thickening 30 forms an undercut in the axial direction with the elevation 19 of the tongue 18. To resolve the undercut, the tongues 18 must deform radially outwards again. This is usually possible without further ado, but not when in a plugged-in state (as in Figure 2 shown) the built-in part is plugged into the socket 8. In the inserted state, the connector 8 is inserted into the mounting opening 35 of the built-in part 3 in such a way that a deformation of the tongues 18 radially outwards is prevented, at least in some areas. The positioning element 1 is therefore locked to the magnet arrangement 2. This is supported in particular by the fact that on the outside of the tongues 18, or the socket 8, there is a support element 26 for supporting the tongues against the built-in part. For a clean locking of the magnet arrangement 2 with the positioning element 1, the support element 26 can, as shown, protrude the same distance from the socket 8 in the radial direction, as can centering elements 25 arranged on the outside for centering the built-in part 3 plugged onto the socket 8. In the present example, there are several centering elements 25 distributed around the circumference of the nozzle 8 in the circumferential direction (cf. Figure 5 ). A centering element 25 has the shape of a circumferential centering collar arranged around the outer surface and in the area of a base of the nozzle 8.

In the in Figure 2 shown mounted state of the positioning element 1 with the magnet arrangement 2 in the built-in part 3 can therefore be the magnet arrangement 2 cannot be detached from the positioning element 1. If a force is applied to the magnet 15 in the axial direction, the connection between the positioning element 1 and the built-in part 3 is released. In the plugged-in state of the built-in part on the socket of the positioning element 1, there is therefore a first which effectively connects the built-in part 3 with the positioning element 1 Force is less than a second force that effectively connects the positioning element 1 to the magnet arrangement 2, since the operative connection of the built-in part with the positioning element is based only on a frictional connection, while the operative connection of the magnet arrangement with the positioning element 1 is based on a positive connection in addition to a frictional connection (undercut between Tongue 18 and pin 14). This has the advantage that when the cast concrete segment 4 is removed from the formwork, due to the magnetic force acting on the magnet 15 of the magnet arrangement 2 in the axial direction, the magnet arrangement 2 remains on the metal formwork together with the positioning element 1, while the cast-in part 3 remains in the concrete segment 4 with exposed mounting opening 35 remains.
