Description

The invention relates to a transport anchor system for transporting an object, in particular precast concrete part, comprising an anchoring means, which is intended to remain in the object.

Usually, in a transport anchor system anchoring means is poured close to the surface in a precast concrete part, wherein by means of a freed opening to the concrete surface, the anchoring means remains accessible after curing of the precast concrete part. A means of transport such as a crane can thus be coupled to the anchoring means for the purpose of transporting the precast concrete part. After the prefabricated concrete part has been installed or set up according to plan, protruding components, if present, are separated or welded off and the opening is usually closed by means of a plug or filled with concrete. However, it often comes to a release of simply constructed plug. Complex stoppers with less tendency to dislodge, in turn, result in an increased manufacturing overhead for the stoppers and the lifting anchor system. From the publication EP0688922B1 is such a system with a transport anchor 12 for precast concrete parts, a screw-in load receptor 40 and a screw-plug 21 known. The screwing takes place with this system near the surface. In principle, transport anchor systems can also be used for transporting any compact heavy-duty objects made of rock and / or minerals such as a stone cube. In a recess then the anchoring means is fixed, in particular cast in concrete.

The abovementioned features known from the prior art can be combined individually or in any desired combination with one of the objects according to the invention described below.

It is an object of the invention to provide a further developed transport anchor system.

To solve the problem is a transport anchorage system according to claim 1. Advantageous embodiments will become apparent from the dependent claims.

To achieve the object, a transport anchor system for transporting an object, in particular precast concrete element, comprising an anchoring means, which is intended to remain in the object, and an elongated connecting element for releasably connecting with the anchoring means within the object for the purpose of transporting the object, the Connection element at its upper end a connection device for releasably connecting a load receiver for a means of transport or the means of transport for transporting the object and at its lower end comprises a coupling means for releasable, positive coupling with the anchoring means, wherein the anchoring means at its upper end a lesser Has transverse extent than at its lower end.

An anchoring means may be a component of, for example, metal or plastic, or an inner object contour or concrete contour within the object, such as a ledge or bevel of an opening.

To remain in the object determines means that the anchoring means is such that the anchoring means can remain before and after a transport of the object in the object. In particular, the anchoring means is such that it can withstand the environmental conditions within the object without a significant loss of load capacity even for a longer period of time, for example one year. If the anchoring means is a component, then the anchoring means is basically such that it is concreted or fixed in the object.

An elongate connection element means that the connection element is visibly longer than it is wide or deep or longer than its diameter. Likewise, the defines Direction of this elongated extension a longitudinal axis of the lifting anchor system.

Releasable connection means non-destructive solvable or intended for multiple loosening and connecting.

A connection element which allows detachable connection with the anchoring means within an object is such that it can be inserted through a generally narrow opening of the object and handled from the outside so that the connection element is connected within the object with the anchoring means and can also be solved.

The lower end of the connecting element faces the anchoring means. The upper end of the terminal is opposite the lower end, i. the upper end and the lower end are opposite ends of the terminal member in the longitudinal direction.

The upper end of the anchoring means faces the connection element. The lower end of the anchoring means is opposite the upper end, i. the upper end and the lower end are opposite ends of the anchoring means in the longitudinal direction.

Depending on the orientation or view, "bottom" and "top" may also be "left" or "right". As long as a view can be rotated in such a way that one end is at the top and / or one end at the bottom, there is an "upper end" or "lower end" within the meaning of the present invention.

Lower end can also be described with reference to the object in the direction of the object center. The upper end can be described accordingly with directed from the object to the outside. The lower end points in the opposite direction as the upper end. Depending on the orientation or view of the object can thus, for example, in a 90 ° rotation of the object together with lifting anchor system in the counterclockwise direction, the "bottom end" is actually the right end and the "top end" is the left end.

Connecting a load receiver for a means of transport or the means of transport means that either a load receptor for coupling a means of transport can be connected to the connection element or the means of transport can be coupled directly to the connection element.

The connection device extends in the mounted state in the longitudinal direction over a defined connection portion. This connection section preferably adjoins substantially the object surface or the upper end of a covering, so that a connection of a load receiver or transport means can take place substantially flush with the object surface or at least close to the object surface. The coupling device extends in the mounted state in the longitudinal direction over a defined coupling portion. This coupling section extends at a distance from the object surface or the upper end of a Ummantellung down, so that the coupling device or the coupling portion is in particular completely remote from the surface within the object. In particular, the object surface is an outer surface of the object, i. the object surface is exposed to external environmental influences. In particular, the object surface is a concrete surface.

In the assembled state means that for a transport, the anchoring means is scheduled coupled to the connection element and / or the connection element is connected according to plan.

Transverse expansion means the extension of the anchoring means transversely to the longitudinal direction, ie in particular a depth and width or a diameter.

An object, in particular precast concrete element, is basically a heavy-duty object and / or a one-piece or one-piece object with a weight of normally over 500 kg.

In particular, the object is made of rock and / or contains minerals. In general, the object may be e.g. be a stone cuboid or boulder.

By providing a transport anchor system with an elongate connection element, which can be connected at its upper end to a load receptor for a means of transport or the means of transport for transporting the object, can be detachably, positively coupled to an anchoring means at its lower end within the object, the upper end of which has a smaller transverse extent than the lower end thereof, a plug with a particularly simple holding strength can be used to seal an opening or access opening to the anchoring means in the object. Even filling the opening or access opening with concrete can thus enable a particularly high-quality closure of the opening or access opening permanently or at least for many years or decades.

In addition, the separation of a protruding over the object surface component of the transport anchor system can be omitted, because all components that are provided for overhanging the object surface can be particularly easily solved or decoupled, so are non-destructive solvable.

In one embodiment, the anchoring means comprises a coupling device for detachable, positive coupling with the coupling device of the connecting element, and the anchoring means and the connecting element are such that in the mounted state for transporting the object, in particular precast concrete part, between the coupling device and an object surface, or between the coupling device and an upper end of a casing for providing an access opening to the anchoring means - a distance of at least 5 cm and / or at least equal to the maximum transverse dimension of the anchoring means.

Transverse expansion means the extent of the anchoring means transverse to the direction in which the distance is to be measured, that is transversely to the longitudinal direction. In particular, the maximum transverse dimension of the entire anchoring means is meant or in a direction transverse to the longitudinal direction. In particular, the maximum transverse extent is at the lower end of the anchoring means.

This distance allows after loosening the connecting element following the successful transport, for example, a thread-free opening with preferably smooth wall over a distance corresponding length in the longitudinal direction.

This opening in turn allows the use of a simple shaped plug. By the length which is at least 5 cm and / or at least equal to the transverse extent of the anchoring means, a sufficiently large contact surface with the concrete or a Ummantellung the lifting anchor system for a reliable holding the plug in the opening can be made possible. In one embodiment, the stopper of the transport anchor system made of plastic or a material swellable by the absorption of water, so this plug is able to swell by moisture absorbed over time and thus to achieve a particularly high adhesive force. If the stopper is made of a different material, the static friction alone ensures sufficient support even without provision of a thread in the stopper. Particularly simple shaped plugs can thus close the opening particularly reliably and at the same time be manufactured with little effort. If the opening is filled with concrete, furthermore, the surface-distant arrangement of the coupling device ensures that even with corrosion, this can not penetrate to the object surface.

In one embodiment, the anchoring means and the connection element are such that, when the object, in particular precast concrete, is transported, the load of the object at a depth of 9 cm or more below the object surface - or below the upper end of the envelope - of the anchoring means, in particular from the coupling device, is transmitted to the coupling device.

This surface-distant coupling between the anchoring means and the connection element enables a simply shaped, free opening for the use of a simply shaped, cost-effective and reliably functioning plug. In addition, the transport anchor system allows in this way, after removal of the connection element of the object, in particular precast concrete part to close the opening with concrete, without fear of corrosion marks.

As explained above in connection with "below" and "above", depending on the viewpoint, "depth" can also be horizontal as well as vertical.

The same effect as the 9 cm or more can alternatively or additionally be achieved by an embodiment in which the anchoring means and the connecting element are such that when transporting the object, in particular precast concrete part, the load of the object at a depth below the object surface - or below the upper end of the Ummantellung - is transmitted from the anchoring means, in particular from the coupling device to the coupling device, wherein the depth corresponds to at least twice the maximum transverse extent of the connection element.

Transverse expansion means the extension of the connecting element transversely to the direction in which the depth is to be measured, ie transversely to the longitudinal direction.

These effects can be synergistically enhanced by the arrangement resulting from the combination of the two previous embodiments.

In the construction of lifting anchor systems has been followed the general view, the mechanical load coupling done as close to the surface, because by a near-surface force coupling is the emergence of undesirable moments, ie transverse force multiplied by distance, prevented or reduced, which weaknesses of the anchorage or Connection connections of the transport anchor may result.

In the present case, however, the finding has been made that by laying the load coupling in the abovementioned depth range during operation no excessive force moments and thus no danger emanate thereby, but at the same time this laying of the load coupling in the above specified depth range the use of simply shaped plug in particular reliable way allows.

Embodiments of the invention will be explained in more detail with reference to figures. Features of the embodiments may be combined individually or in a plurality with the claimed subject matter.

In one embodiment, the transport anchor system comprises a shroud 7 for providing an access opening to the anchoring means 2. Access opening means a void, ie free of concrete or other object material, from the object surface 10 to the anchoring means 2 or to the coupling device 9 of the anchoring means 2. By providing The access opening can be moved for transport, the connection element 3 to the object 1, in particular precast concrete, anchoring means 2 to couple the connection element 3 with the anchoring means 2 within the object 1, in particular precast concrete part. The Ummantellung then protects the surrounding concrete from damage, so that the coupling device 9 is not polluted by crumbling concrete and becomes inoperative.

By the Ummantellung 7, the coupling device 9 of the anchoring means 2 can be kept free of concrete, especially during the casting and curing of the object 1, in particular precast concrete part, with the integrated anchoring means 2. Preferably, the Ummantellung 7 is to remain in the object 1, in particular precast concrete part , certainly. Alternatively, the casing 7 can be removed after the concrete has hardened, leaving an opening from the object surface 10 to the anchoring means 2 or its coupling device 9, which allows access of the connection element 3 to the anchoring means 2. Preferably, however, the wrapping 7 is adapted to line an access opening from the object surface 10 to the anchoring means 2. In particular, the Ummantellung 7 sheathed in mounted state, the connection element 3, the connection device 4 and / or the coupling device 5 is preferably completely or adjacent thereto.

Preferably, the Ummantellung 7 adjoins the object surface 10 in the assembled state or is in particular slightly below the object surface 10. Preferably, the Ummantellung 7 is oriented in the longitudinal direction 11. Preferably, the inner contour of the Ummantellung 7 is adapted to the outer contour of the connection element 3, such that a game is present, so that a smooth insertion and removal of the connection element 3 in the Ummantellung into and out of it is guaranteed.

Preferably, the inner contour of the casing 7 is adapted at its lower end to the transverse extent of the upper portion of the anchoring means 2, such that a liquid concrete can not get to the coupling device 9, but is retained by the Ummantellung 7. In this case, the Ummantellung 7 put on the anchoring means 2 in the longitudinal direction 11 as in an I-shock. Alternatively or additionally, the Ummantellung 7 can rest in the longitudinal direction 11 from the outside to an upper portion of the anchoring means 2 in order to enclose the anchoring means 2 tight.

Preferably, the Ummantellung 7 in the longitudinal direction 11 has a circular or rectangular cross-section. In particular, the transverse extent of the sheathing 7 over the longitudinal direction 11 is constant and / or less than the transverse extent of the lower end of the anchoring means 2.

In one embodiment, the anchoring means 2 forms an undercut in the longitudinal direction 11, in particular starting from the object surface 10 or the upper end of the casing 7. A particularly simple coupling is thus made possible. The opening or access opening expands downwards in one embodiment. A particularly simple coupling with a reliable load or power transmission can be made possible.

In one embodiment, the connection element 3 may be connected to the anchoring means 2 by a dovetail connection (see FIG FIGS. 5 and 6 ) or a screw connection (see Fig. 1 . 2 . 3 and 4 ). A particularly reliable positive connection can thus be obtained.

In particular, the coupling device 5 is a dovetail, preferably consisting of several parts, and / or the coupling device 9 is a dovetail receptacle. Alternatively or additionally, the coupling device 5 comprises a thread, preferably internal thread, and / or the coupling device 9 has a complementary thread, preferably external thread.

In one embodiment, the anchoring means 2 is an open-topped or open-topped box, preferably with a rectangular, oval or rotationally symmetrical cross-section, so that preferably an undercut is formed which in particular has a greater longitudinal extent than transverse extent of the box, but preferably no longer when the double transverse extent is long. A sealed against liquid concrete and particularly simple anchoring means can be provided in this way with very little manufacturing effort.

In one embodiment, the anchoring means 2 comprises a steel plate (cf. FIG. 8 ) with an anchoring opening 30 or consists thereof. One or two, in particular L-shaped coupling elements 14 (cf. FIG. 7 ) can preferably be passed through this anchoring opening 30 and latched behind it or hooked, so in particular be made laterally on the opposite side of the steel plate for concern. A sealed against liquid concrete and particularly simple anchoring means can be provided in this way with very little manufacturing effort. Alternatively, the anchoring means 2 can be introduced by a lost shape in the object 1, in particular precast concrete part, as an inner object contour or concrete contour, preferably with a rectangular, oval or rotationally symmetrical cross section, so that an undercut is formed. General has a rectangular Cross-section such as an upwardly open trapezoidal shape has the advantage that in this way torsional moments about an axis in the longitudinal direction 11 can be reliably absorbed. An oval cross section is also able to largely absorb torsional moments and, incidentally, to forward the loads or forces uniformly via a positive connection. A rotationally symmetrical cross-section, such as in the case of an upwardly open conical shape, allows a particularly uniform transmission of a force through a positive connection.

In one embodiment, the transport anchor system is such that the upwardly open box extends to the object surface 10 and thus simultaneously provides the jacket 7, or abuts the jacket 7 or an access opening. If the box simultaneously provides the shell 7, the number of parts can be reduced.

In one embodiment, the connection element 3 is multi-part and / or holds several parts together over a common transverse axis 12. A multi-part connection element 3 allows a particularly simple coupling. Holding together via a transverse axis 12 means that the held together parts are threaded onto the transverse axis, ie the parts have a transverse bore or a slot for passing through the transverse axis 12. The holding together of several parts allows the provision of a relative to the other parts movable locking member 13 for coupling.

In one embodiment, the connection element 3 comprises-in particular in the form of several parts-one or two or exactly two coupling elements 14 with a lateral projection 15 and a locking element 13, such that for coupling with the anchoring means 2 the at least one coupling element 14 to the anchoring means 2 is supplied until the projection 15 has reached a correspondingly shaped lateral recess, and only then the locking member 13 is supplied to the anchoring means 2 until the locking member 13 has reached the projection 15, so that the projection 15 by the locking element 13 in the recess is held.

Feeding means inserting, pushing in or pressing in the opening or access opening in the direction of anchoring means 2, as shown by way of example in FIGS FIGS. 5 and 6 illustrated by arrows down.

This embodiment enables a smooth assembly and the transfer of particularly high forces.

A lateral projection 15 extends in particular as the coupling device 5 generally in the transverse direction, in particular in a scheduled feeding for coupling in the direction of the undercut or a recess of the anchoring means 2. In particular, the projection 15 in the lower region of the coupling element 14 or at its lower end arranged.

Preferably, the projection 15 is wedge-shaped and / or has a slope to the longitudinal direction 11, in particular with a flat surface (see FIGS. 5 and 6 ). But even a paragraph form is possible in an alternative or supplementary design, as exemplified in Fig. 7 shown. In any case, by these forms, which widen downwards, the upper end of the anchoring means 2 with respect to the lower end of a smaller transverse extent. If two coupling elements 14 are provided, the respective projections 15 extend in the opposite direction in order to be able to absorb particularly large loads or forces. Exactly two coupling elements 14 have the advantage that then the locking element 13 can be fed centrally between the two coupling elements 14 and thus simultaneously by two locking elements 13 can be detected in a coupled state by only one locking element 13.

In particular, the projection 15 extends over at least 10%, preferably at least 20%, of the length of the coupling element 14 in the longitudinal direction 11. The extent of the projection 15 in the transverse direction is at least 30%, preferably at least 50%, and / or at most 5 times , preferably at most twice the transverse extent of the coupling element 14, ie above the projection 15 or compared without the projection 15. A smooth feeding and a reliable transmission of particularly high Forces can be made that way. In particular, a minimum width of the anchoring opening 30 corresponds to the sum of the transverse dimensions of the coupling element 14 and the projection 15. Alternatively or additionally, a minimum width of the anchoring opening 30 corresponds to the sum of the transverse dimensions of exactly two coupling elements 14 and only one projection 15, in particular one of the two coupling elements 14 can be assigned. In particular, the transverse extent of a coupling element whose extension transverse to the longitudinal extent without consideration of the projection. Preferably, the locking element 13 has a transverse extent which corresponds approximately or at most to the difference between a width of the anchoring opening 30 and the coupling element 14 or the coupling elements 14. Preferably, the minimum width or the approximate width of the anchoring opening 30 are as large as the sum of the cross sections or cross-sectional transverse dimensions of the locking element 13 and all coupling elements 14. Alternatively or additionally, the minimum width or the approximate width of the anchoring opening 30 are as large as the sum of the cross sections or Querschnittsquerausdehnungen all the coupling elements 14 and all projections 15. Preferably, the width or minimum width of the anchoring opening 30, the transverse extent of the locking element 13 or the coupling element 14 or the coupling elements 14, the cross-section or cross-sectional transverse extent and / or the transverse extent of the projection 15 are each oriented parallel to each other. In particular, in this context, the cross-section or the cross-sectional cross-dimension denotes a maximum length of a cross-section, in particular in the direction of the width of the anchoring opening 30 and / or on the plane or in a plane of the anchoring opening 30, preferably at a location with a minimum width of the anchoring opening 30.

Correspondingly shaped lateral recess means that the recess, in particular as the coupling device, is adapted to the shape of the projection 15 or essentially corresponds to the outer contour of the projection 15. A particularly reliable coupling can thus be ensured. The recess preferably has a slope, in particular with a plane Surface. When the protrusion 15 and the recess are a slope, the inclination angles of the slopes are substantially or exactly the same.

In particular, the anchoring means 2 in the region of the transverse axis 12 has a greater transverse extent than the coupling element 14 or each of the coupling elements 14. A particularly reliable determination of the coupling element or elements in the coupled state can thus be made possible.

In one embodiment, the at least one coupling element 14 has a transverse bore for passing through a transverse axis 12 and / or the locking element 13 has a slot 16 for passing through a transverse axis 12.

Due to the transverse bore, the coupling element 14 or two coupling elements 14 can be fed to the anchoring means 2 simultaneously by pressing on the transverse axis 12 or at least one coupling element 14. Through the slot 16 allows the locking element 13 can be fed independently of a coupling element 14 to the anchoring means 2, because if the at least one coupling element 14 has a transverse bore and the locking element 13 has a slot 16 for performing a particular common transverse axis 12, then the at least one coupling element 14, together with the transverse axis 12, are moved relative to the locking element 13 in the direction of anchoring means 2, that is, fed while the locking element 13 remains in the area of the object surface 10 or at the upper end of the shell 7, as in FIG FIG. 6 shown. The locking element 13 is then in a raised position and / or is at a lower stop surface of the elongated hole 16 on the transverse axis 12 at.

Due to the lateral projection 5 a deflection in the form of an elastic bending and / or tilting of the coupling element 14 relative to the longitudinal axis 11 is required to the lateral projection 5 through the opening in the object surface 10 and the object 1, in particular precast concrete part, or through the Access opening the Ummantellung 7 to move to the recess or the undercut. Because the locking element 13 preferably during the feeding of the Coupling element 14 remains in the region of the object surface 10 or at the upper end of the sheath 7, a space for this deflection is provided. After reaching the recess or the undercut, the projection 15 can engage in the recess or the undercut, hook, fall or be applied to it.

The above-mentioned free space can be filled or taken in any case by the locking element 13 by its supply to the anchoring means 2 after reaching the recess or the undercut

However, until the recess or the undercut is reached, this clearance allows deflection of the coupling element 14, as described above.

In particular, the parts of the connecting element 3 are held together closely adjacent to one another and / or to one another on the transverse axis such that feeding of the coupling element 14 relative to a stationary locking element 13 is possible in a smooth manner. The deflection is then done by bending. A robust, multi-part connection element 3 can thus be provided.

Alternatively, the parts of the connecting element 3 with such a loose game next to each other and / or held together on the transverse axis that tilting of the coupling element 14 or two coupling elements 14 at the same time when feeding to the anchoring means 2, in particular at dormant locking element 13 is preferably possible in the raised position , A particularly low force can therefore already be sufficient for feeding the coupling elements 14 until they reach the recess or the undercut.

Preferably, the connection element 3 has a stop 17 for the object surface 10 or the upper end of the casing 7. In particular, the connection element 3 is such that the stop 17 touches on reaching the recess or the undercut by the lateral projection 15 on the object surface 10 or the upper end of the casing 7. the Users can be displayed so easily the achievement of the intended feed position by the projection 15.

The locking element 13 is also supplied after reaching the recess or the undercut by the projection 15 also in the direction of the anchoring means 2, in particular in the above-mentioned space, preferably around this clearance between the coupling element 14 and sheath 7 or between the coupling element 14th and a wall or concrete wall of the opening or between two coupling elements 14 to fill.

Preferably, the locking element 13 fills the free space in the region of the projection 15, particularly preferably completely. The locking element 13 can thus spread or wed the coupling element 14.

Anyway, by supplying the locking element 13 as in FIG. 5 illustrates the projection 15 brought to rest on the recess or the undercut and positively detected in this coupled state, so the projection 15 held in the recess. The locking element 13 is then preferably in a pulled-down position and / or abuts with an upper abutment surface of the elongated hole 16 on the transverse axis 12 in order to indicate to the user the achievement of the scheduled feed position.

In the coupled state, an empty space is preferably provided between the connection element 3 and a base of the anchoring means 2. This allows reliable mounting and coupling, even if, for example, some dirt has fallen to the bottom of the anchoring means 2.

If the cross section of the connecting element 3 in the region of the transverse axis 12 is rectangular, the total width of the at least one coupling element 14 and the locking element 13 together is approximately as large as the depth orthogonal to the transverse direction, ie parallel to the transverse axis 12. Preferably, the total width is greater than the depth, but preferably not greater than twice the depth. In particular, the locking element 13 is approximately as long as the coupling element 14 or the two coupling elements 14.

In one embodiment, the locking element 13 is arranged centrally between two coupling elements 14, in particular centrally along the transverse axis 12, and / or the lateral projections 15 of the coupling elements 14 respectively facing away from the locking element 13, so extend in opposite directions transversely to the longitudinal direction 11 Direction. Thereby, the locking element 13 can simultaneously two coupling elements 14 in the coupled state, i. upon contact of a projection 15 on the recess or the undercut, notice.

In particular, the parts of the connecting element 3 are held together at the transverse axis 12 by a screw fixing 18 or bolt fixing 31 or bolt-like fixing. This makes it possible to provide a connecting element 3 that is particularly simple to construct and to produce. In addition, worn coupling elements 14 can be easily exchanged.

The FIG. 5 also shows by way of example the connection of a load receiver 6 preferably in the form of a U-shaped bend 27 to the connection element 3, preferably to the screw fixation 18, the transverse axis 12 or a coupling element 14. In particular, the connection is made after the detection of the coupling by the locking element 13th

Preferably, the screw fixation 18, the transverse axis 12, the coupling element 14 and / or the locking element 13 are made of metal, preferably steel. In particular, the anchoring means 2 is made of plastic or metal, preferably steel or aluminum. Alternatively or additionally, the connection device 4 for a means of transport, for example in the form of a tab with a bore or a permanently connected wire rope or ring, also directly on the screw fixation 18, a particular projecting transverse axis 12 or on one or preferably two coupling elements 14 are provided.

A further aspect of the invention relates to a method for mounting a transport anchor system, in particular according to the invention described in introduction to achieve the object, wherein first at least one coupling element 14 is fed into an opening in an object surface 10 or an access opening provided by a sheath 7 to an anchoring means 2 until a lateral projection has reached a recess or an undercut of the anchoring means 2, and then the locking element 13, which until then has rested in the area of the object surface 10 or the upper end of the casing 7, is fed into the region of the projection 15 in the direction of the anchoring means 2 is to keep the projection 15 in the recess or the undercut for coupling.

A particularly simple mounting and transporting particularly heavy objects, especially precast concrete parts, can thus be achieved with the simultaneous use of particularly simple-shaped plug or high-quality concrete fillings for the purpose of closing the opening.

In one embodiment, the connection element 3 is in one piece and / or in one piece, such as in the FIGS. 1 and 2 illustrated.

One-piece means consisting of one or more indissolubly interconnected parts. In one embodiment, as in FIG. 2 can be represented, the connection element 3 is in one piece, wherein a plurality of components including the load receptor 6 in addition to the screw still connected to each other, for example, welded, and thus are one-piece. The FIG. 2 leaves open by the sectional view, however, whether only a releasable screw or a non-detachable connection in the area indicated by reference numeral 4 is present.

One-piece means made of only a single part, preferably forged. A one-piece connection element 3 is for example in FIG. 1 shown. In particular, the connection element 3 is made of metal, preferably steel.

In one embodiment, the connecting element 3 is rod-shaped, in particular rod-shaped or bolt-shaped.

This allows easy feeding through a narrow opening or feed opening and also the use of simple, cylindrical plug, which then can be produced as the connection element 3 with very little effort. The same applies to a bar shape or bolt shape.

Preferably, the connection element 3 has a circular cross section, preferably constant over the entire length, ie in the longitudinal direction 11. This allows a particularly uniform power transmission.

In a further embodiment, the anchoring means 2 is conical and / or disc-shaped.

A cone shape, for example, in the FIG. 3 is shown, can allow a particularly strong anchoring and at the same time homogeneous power transmission. A disc shape is particularly easy to produce and also causes a particularly firm anchoring, as in FIG. 4 shown. Both a cone shape and a disk shape also allow, for example, a support on a reinforcing bar, so that particularly heavy objects, especially precast concrete parts, can be transported. Preferably, the anchoring means is rotationally symmetrical shaped to accommodate the forces and loads particularly uniform and transferable. The conical shape or disc shape is in particular arranged at the lower end of the anchoring means 2, the upper end having a smaller transverse extent for this purpose. In particular, in the anchoring means, the transverse extent at the lower end is greater than its longitudinal extent, but preferably less than three times as large.

The FIG. 4 shows an embodiment in which a head of a screw 20 forms the lower end of the anchoring means 2, wherein the thread of the screw 20 at the upper end of the coupling device 9 forms. On the head of the screw 20 and between the head and the thread of the screw 20 is a disc 22 threaded on the screw and is supported on the head of the screw 20. This embodiment of an anchoring means 2 can be manufactured with very little effort and thus provided particularly inexpensive.

In particular, as in FIG. 4 represented, the Ummantellung 7 in one embodiment at the lower end a sleeve 21, whose inner diameter is adapted to the thread of the screw 20, so that a smooth sliding of the casing 7 with the sleeve 21 through the thread to the disc 22 is possible. In particular, the sheath 7 including the sleeve 21 form a dense barrier against liquid concrete and / or moisture.

In particular, the sleeve 21 has a smooth inner surface. Alternatively or additionally, an internal thread for screwing onto the thread of the screw 20 may be provided.

In one embodiment, the anchoring means 2 provides a receptacle 23 for connection to a casing 7, such that the upper end of the anchoring means 2 or the coupling device 9 can be sealed for protection against liquid concrete and / or moisture.

Clogging of the upper end of the anchoring means 2 or the coupling device 9 can be avoided and a reliable operation can be ensured. In addition, in the case of an anchoring means 2 made of metal or with metallic components, corrosion can be counteracted or even avoided by providing a receptacle 23 for a cover for protection against moisture.

In particular, the sleeve 21 protects the screw 20 against liquid concrete, when the sleeve 21 is pushed onto the screw 20 and also against moisture in providing an internal thread of the sleeve 21 after screwing onto the screw 20. The thread of the screw 20, in particular a lower Part of the thread, forms the receptacle 23 as in FIG. 4 shown.

The FIGS. 1 . 2 and 3 show a receptacle 23, which in one embodiment has the shape of a cylindrical shell surface, which is adapted to the inner diameter of the Ummantellung 7 so that the upper end of the anchoring means 2 or the coupling device 9 are sealed for protection against liquid concrete and / or moisture can. To protect against liquid concrete is already sufficient clearance fit between the receptacle 23 and the Ummantellung 7, so that a simple assembly is possible. A transitional fit or interference fit makes assembly difficult, but provides a wet seal. In one embodiment, a gluing or fusing the Ummantellung 7 is provided with the receptacle 23.

In particular, the receptacle 23 has an extension in the longitudinal direction 11 which is substantially as long or longer as the lower region of the anchoring means 2 from the receptacle 23 to the lower end of the anchoring means 2.

In the FIGS. 5 and 6 is a receptacle 23 in one embodiment, a flat, circumferential support on which the sheath 7 can be placed resting surface.

In one embodiment, an identification ring 24 is provided, which can be fixedly or detachably connected to the casing 7 and / or in the assembled state is aligned with the object surface 10 or the upper end of the casing 7. In particular, the identification ring 24 is provided for a permanent remaining in the object 1, in particular precast concrete part. The identification ring 24 is used to display the opening or access opening, that is, to indicate the location where a transport anchor system for transporting the object 1, in particular precast concrete, can be used. In particular, the identification ring 24 displays information to the user, such as maximum payload.

Preferably, the maximum load of a lifting anchor system is at least a quarter or a half tonne. Thus, by means of several transport anchor systems, an object 1, in particular precast concrete part, of several tons of weight transported by a means of transport such as a crane.

In one embodiment, the connection device 4 and / or the coupling device 5 are formed by a screw thread. Simple connection and coupling can thus be made possible.

In particular, the coupling device 5 comprises an internal thread and the coupling device 9 has an external thread. The usually weather-resistant and therefore high-quality and expensive material, which is preferably used for the anchoring means 2 due to the fate in the object 1, in particular precast concrete, can be saved or the saved material at the lower end of the anchoring means 2 for improved anchoring be used.

In addition, the amount of possibly corrosion-prone material can be reduced.

The connection device 4 can be either an internal thread or an external thread. In particular, an external thread as in FIG. 2 used to screw it to a load receiver 6 with a larger cross-sectional area compared to the connection element 3. The connection is simplified. In particular, the load receiver 6 comprises two plates, of which a lower plate 25 has the thread or internal thread for the connection device 4 and / or the upper plate 26 a connecting means, in particular a U-shaped bend 27 preferably made of metal, for connection to the transport.

In particular, the connection device 4 comprises an internal thread. An internal thread as connection device 4 is particularly suitable for a load receiver 6 whose cross-sectional area is smaller than the cross-sectional area of the connection element 3, as in FIG FIG. 1 shown. In particular, the load receptor 6 for connecting to the transport means may comprise a metal chain or a wire rope 28, which preferably provides a closed loop.

Preferably, the two ends of the metal chain or the wire rope 28 are fixed in a connecting element 29. Preferably, an external thread is provided by the connecting element 29 for connection to the connection device.

If the connection device 4 and the coupling device 5 are formed by a screw thread, a securing device for fixing a screwed state of the connection device 4 and / or the coupling device 5 is preferably provided, preferably by a locking pin which can be attached and released in particular manually or by gluing. Alternatively or additionally, a screw thread can be a left-hand thread and the other screw thread a right-hand thread. By the aforementioned alternatives or complementary embodiments it is avoided that the connection element 3 can not be unscrewed from the anchoring means 2 after transport. Preferably, a not shown locking means, preferably a bolt-like pin, is provided for locking the screw connection of the connecting device 4 after screwing on the connecting element 3. This also avoids that the connection element 3 can not be unscrewed from the anchoring means 2 after transport.

If an object 1, in particular precast concrete part, to be transported, in particular first the load receiver 6 is connected to the connection element 4 and / or the connection element 4 is coupled to the anchoring means 2.

If a jacket 7 is used, it is already in the opening in the object 1, in particular precast concrete element, and provides the access opening. In principle, it is also possible that the sheath 7 is inserted only for transporting in the opening to the receptacle 23 and removed again after transport.

Finally, the means of transport is connected to the load receiver 6 or directly to the connection element 4 and the object 1, in particular precast concrete, transported to its destination. After the transport it will be Connection element 4 decoupled from the anchoring means 2 and removed. The opening in the object surface 10 or the access opening of the sheath 7 is then closed or concreted by a relatively simple shaped plug. The anchoring means 2, in particular also the sheath 7, remain in the object 1, in particular precast concrete part.

In the FIGS. 1 to 6 the distance 8 is preferably at least 5 cm and in particular at a depth of 9 cm or more below the object surface 10, the recess or the undercut or the external thread for transmitting the forces during transport of the object 1, in particular precast concrete component, on the projection 15 and an internal thread of the connecting element 4th

In one embodiment, which is a development, not shown, of the transport anchor system of FIG. 5 represents, - is provided a blocking means, such that an unintentional moving out of the locking member 13 from its supplied position or pulled down position is blocked by the blocking means.

The inserted position means the position in which the locking element 13 holds the projection 15 of the coupling element 14 in the lateral recess of the anchoring means 2 and / or the transport anchor system is ready for operation.

If, for example, the transport anchor system is fastened from below, then gravity could cause the locking element 13 to move outwards and thus unintentionally and unintentionally release the coupling between connection element 3 and anchoring means 2. In a horizontal orientation, the locking element 13 could also unwanted and unplanned move out of the supplied position by vibrations. And even with the top-down orientation exemplified in the figures, risks could arise from misuse or misuse. By a blocking means specified above, the unwanted and unscheduled moving out and release of the locking element 13 can be prevented in a particularly simple and effective manner.

In particular, the blocking means comprises a U-shaped pivoting part which can be pivoted about the transverse axis 12. Preferably, the pivotal part is approximately shaped and aligned like the arch 27 as in FIG Fig. 5 , If the pivoting part is in a pivoting position above the locking element 13, ie in its blocking position, the pivoting part blocks outward movement of the locking element 13. Preferably, a clearance or gap is provided so that the locking element 13 moves in the direction of the clearance or gap in the direction of a Move outward moving, the projection always held securely in the recess and the transport anchor system remains operational. Through this game or the gap a smooth swinging is possible.

In particular, a preferably U-shaped load receiver 6 is mounted transversely to the transverse axis 12 on the pivoting part. If a tensile force is introduced by the means of transport via the load receiver 6, the pivoting part automatically pivots into its blocking position via the locking element 13.

Preferably, the pivoting part is constructed so that a preferably U-shaped arc 27 (similar to that in in FIG Fig. 5 illustrated arc) with a about the transverse axis 12 rotatably mounted stop 17 (similar to the in Fig. 5 shown stop) is connected, preferably in one piece. Additional parts for the provision of a blocking agent can be saved.

In particular, the blocking means comprises a latch, preferably an elongated and / or bolt or T-shaped latch. Preferably, the bolt can be locked and released by a relative movement to the pivoting part.

The pivoting part preferably has a passage opening, in particular parallel to the transverse axis 12. The bolt can thus be pushed in parallel to the transverse axis 12 in the pivoting part.

Preferably, the passage opening is arranged in the region of the play or the gap, such that by the insertion of the bolt into the through hole the bolt further limits the play or the gap in the direction of moving out of the locking element 13 from its supplied position, that is reduced. In this way, on the one hand, the pivoting part can be pivoted particularly smoothly, especially without a slide-in latch and on the other hand held by pushing the bolt, the locking element 13 is particularly reliable and safe in the inserted position.

Furthermore, a two-stage safety precaution can be realized by the pivoting part and the bolt, because the locking element 13 can not be released until, firstly, the pivoting part has been swung out of the blocking position and, secondly, the bolt has been released.

In particular, the locking element 13 has an arc shape at its upper end. Preferably, the angle section has a constant radius over an angular section. Preferably, the angle section is at least 120 ° and / or at most 180 °. Preferably, the angle section is arranged centered to the longitudinal direction. When pivoting the pivoting part remains the same size of the game or the gap.

In particular, a preferably radially projecting shoulder is arranged at one end or at both ends of the angle section. A pivoting movement of the pivoting part with and / or without a locked latch can be limited, because the latch and / or the pivoting part itself encounter when pivoting out of the blocking position against the paragraph.

In particular, the shoulder protrudes radially beyond the arcuate shape such that in the locked or pushed-in state, the latch can push against the shoulder in the pivoting part by pivoting the pivoting part. Regardless of the pivoting position of the pivoting part, the latch can always ensure reliable retention of the locking element 13 in the supplied position in this way.

In particular, the paragraph is just as much radially out of the arch shape that only the bolt in the locked or pushed-in state in the pivoting part can push against the shoulder, but not the pivoting part itself.

Thus, regardless of the pivoting position of the pivoting part, the locking element 13 can be reliably blocked only by the bolt.

In one embodiment, which is a development, not shown, of the transport anchor system of FIGS. 5 and 6 represents, - the locking element 13 is tapered at the lower end and / or upper end or it is provided a lateral recess, in particular in the direction parallel to the transverse axis 12. In this way, a clearance between the locking element 13 to one or two adjacent coupling elements fourteenth be generated what the in Fig. 6 indicated mounting of the connecting element 2 in the anchoring means 3 simplified. Preferably, a taper is provided towards the end so that the clearance increases towards the end and / or the transverse extent decreases towards the end. Preferably, the locking member 13 is tapered at the lower end or has approximately the shape of an arrowhead, so is substantially triangular.

In particular, the taper or the recess is located at the lower end of the locking element 13 in the region of the recesses in the supplied position or pulled-down position of the locking element thirteenth

Preferably, the locking element 13 and the at least one coupling element 14 are aligned in the pulled-down position of the locking element 13 at the lower end. However, the locking member 13 may protrude in the pulled-down position with a part of the lower end on the coupling elements.

In one embodiment, which is a development, not shown, of the transport anchor system of FIGS. 5 and 6 represents, - has the coupling element 14 or both coupling elements 14 a web in the longitudinal direction. Preferably the web is adapted to the slot 16 of the locking element 13 so that the web can extend into the slot to form a guide for the locking element 13 during feeding of the locking element 13. A particularly easy feeding of the locking element 13 for coupling with the locking means can be made possible.

Preferably, the web is strip-like, in particular with a constant web thickness and / or web width. The web is in particular in the direction of the transverse axis 12 of the coupling element 14 in the direction of the actuating element 13 from. Preferably, the web extends longitudinally in the longitudinal direction.

In particular, locking element 13, coupling element 14 and / or sheathing 7 can be rectangular in order to be able to absorb forces in a horizontal arrangement in an improved manner.

Another aspect of the invention relates to a precast concrete part with the transport anchor system according to the invention described input for solving the problem. In particular, the anchoring means 2 is integrated into the precast concrete part, that is, for example, has been poured by the liquid concrete during manufacture of the precast concrete part, or produced by a lost form during the manufacture of the precast concrete part. Preferably, the undercut, the recess, a lower conical end or disc-shaped end of the anchoring means 2 is disposed below or immediately below a reinforcing bar 19, so that the transport anchor system can be supported when transporting the precast concrete 1 to the reinforcing bar 19, such as in the FIGS. 3 and 4 illustrated. A precast concrete part with a particularly high weight can thus be transported by means of the transport anchor system.

In one embodiment, the connection element 3 has one or more identification tabs. This information can be displayed to the user. In particular, the at least one identification tab is ear-shaped or laterally preferably wing-shaped. In particular, the at least one identification tab is at the upper end of the casing 7 appropriate. In particular, the at least one identification tab is produced in one piece with the casing 7, for example, cast or formed by forming and / or engraving the end of the casing 7. An ear-shaped, laterally extending and / or wing-shaped identification tab has the advantage that it can not only display information to the user in a clearly visible manner, but can also simultaneously serve for fastening the casing 7 and / or a casing.

In one embodiment, the example, for example, in the FIGS. 7 and 8 is shown, the anchoring means 2 comprises a plate or steel plate with an anchoring opening 30 or consists of the plate or steel plate with the anchoring opening 30. The anchoring means 2 can be provided with very little manufacturing effort and also easy under reinforcing bars for a particularly reliable fixation with the Object to be placed. In one embodiment, the at least one coupling element 14 is "L" -shaped. Preferably, then the particular "_" - shaped projection 15 extends transversely, preferably from a lower end of the particular "I" -shaped, longitudinally extending portion of the coupling element 14 to form the "L" shape.

If exactly two coupling elements 14 are provided, the projections 15 of the two coupling elements 14 preferably point in opposite directions, ie laterally to the longitudinal direction. In FIG. 7 is the locking element 13 for clarity, as well as the rest, for example, in the FIGS. 5 and 6 hidden components shown hidden. The FIG. 7 shows an example of a bolt fixation 31, which can be used instead of a screw fixation in the embodiments of the other figures.

Two shoe-shaped or L-shaped coupling elements 14 can be passed through the anchoring opening 30 by compression at the lower end and spread apart behind the anchoring opening 30, in particular by means of the hidden locking member 13 to lock with the lower surface of the steel plate, hook and /or to attach to it. By using this undercut and the anchoring of the connection element 2 with the anchoring means 3 in this manner described a particularly reliable and strong anchoring can be created in an easily detachable manner. In particular, the outer contour of the anchoring opening is adapted to the outer contour of the coupling elements 14, ie, for example, the contours are all angular or rectangular. But also an arcuate contour or arcuate contours are possible.

The FIG. 8 shows an anchoring opening 30 in plan view. In one embodiment, in Fig. 8 is exemplified, the width of the anchoring opening 30, which points in the direction of the transverse extent of the connecting element 3 or the elements 13, 14 and 15, is greater than an opening extent which is perpendicular to the transverse dimension and perpendicular to the longitudinal direction. In one embodiment, the transverse extent of the connecting element 3 is greater than its extension perpendicular to the transverse extent and perpendicular to the longitudinal direction, in particular at the beginning of the projection 15 or at the end of the projection 15 seen in the longitudinal direction. Preferably, the direction of transverse extension and / or width is parallel to the transverse axis 12.

Another aspect of the invention relates to a precast concrete element with an anchoring means 2 for the transport anchor system according to the invention described in the introduction to achieve the object, wherein the anchoring means 2 is poured into the precast concrete by means of concrete and / or fixed therein. Preferably, the anchoring means 2 has been poured during manufacture of the precast concrete part or produced by a lost mold during the manufacture of the precast concrete part. A precast concrete part with a particularly high weight can thus be transported by means of a means of transport for heavy loads.

A further aspect of the invention relates to an anchoring means 2 for a transport anchor system for transporting an object 1 according to the invention described at the beginning to achieve the object, wherein the anchoring means 2 for remaining in the object 1 and for detachable connection with an elongated connecting element 3 of the transport anchor system within the Object 1 for the purpose the transporting of the object 1 is determined, wherein releasably connecting a releasable, positive coupling is meant with a coupling device 5 of the connection element 3, wherein the anchoring means 2 has at its upper end a smaller transverse extent than at its lower end.
