    Transport anchor as well as reinforcement and construction body with the transport anchor
    DESCRIPTION
    The invention relates to a transport anchor as well as a reinforcing body with the transport anchor for square-shaped, in particular mineral-like, large-sized structural bodies, such as plates or beams or supports, which are in particular manufactured from a mineral-like, reinforced, light concrete, in particular. from reinforced porous concrete or foamed concrete. The invention furthermore relates to structural bodies which are provided with the transport anchor and / or the reinforcing body.
    Reinforcement bodies within the meaning of the invention are essentially reinforcement bodies made of structural steel wire.
    The transport anchors of the type according to the invention are made of metal and essentially comprise an anchoring area and a suspension area. The anchoring area is attached to the reinforcement and embedded in the light concrete when casting the large-sized structural member. The suspension area is freely accessible, but usually does not protrude over the structural part.
    The anchoring area is shaped so that it can absorb increased pull-out forces.
    Numerous transport anchors for light concrete structural members are made from flat strip steel (e.g. DE-297.08.469 U1, or DE-299.09.378 U1, DE-298.00.905 U1, WO 80/02185). Such anchors normally comprise a complicated spatial shape and require a necessary mounting effort.
    Furthermore, transport anchors have been made from structural steel wires, which, however, also have a complicated spatial shape and are assembly-tight (for example DE-197.43.412 C2). Furthermore, a transport anchor is known, which is manufactured as a structural steel wire bent through 180 degrees and welded to different spacer bars of a cage reinforcement, so that sufficient pull-out forces can be ensured. Normally, the spatial shape of the known transport anchors significantly disrupts the flow of fresh light concrete mass during the casting and / or flooding process, so that inhomogeneities occur in the solid light concrete produced.
    The object of the invention is to provide a transport anchor that is simple, simple to manufacture and easy to attach to a reinforcement, which moreover requires a very limited volume in the space and which hardly hinders the fresh, light concrete mass during casting and / or floating. and ensures relatively high pull-out forces.
    This object is achieved by the features of claim 1. Advantageous preferred embodiments of the invention are described in the dependent claims.
    The transport anchor according to the invention comprises a relatively simple spatial shape, which does not interfere with the fresh light concrete, which requires little volume and which can be manufactured in a simple manner, in particular also with different dimensions, from mainly structural steel wire or reinforcing wire, so that in a simple manner a relatively long embedding length can be provided depending on the spatial shape of the structural body. In addition, the new transport anchor ensures high pull-out forces based on its spatial shape and the known rough and / or contoured surface properties or surface structure of the reinforcement wire. The transport anchor is arranged in a construction body such that the suspension loop of the construction body is exposed on the surface and can be hung in a hook of a transport means, for example a wreath.
    The invention is further explained in the following example with reference to the drawings.
    Figure 1 shows a front view of the transport anchor according to the invention,
    Figure 2 shows a side view of the transport anchor according to the invention,
    Figure 3 shows a top view of the transport anchor according to the invention,
    Figure 4 shows a front view of a cage reinforcement with a built-in transport anchor according to the invention,
    Figure 5 shows a side view of a cage reinforcement with a built-in transport anchor according to the invention,
    Figure 6 shows a side view of a special embodiment of the transport anchor according to the invention,
    Figures 7a-7d show different bending shapes of the end region of a side leg in a top view of the transport anchor.
    The transport anchor 1 according to the invention is manufactured from a U-shaped or hairpin-shaped bent structural steel wire piece 2, which is preferably provided with side legs 3, 4, preferably of equal length, and a suspension loop 6 forming a U-base 5.
    According to the invention, an end element 8 is arranged between the side legs 3, 4, for example in the area of the free ends 7 thereof, for example in the form of a relatively short, for example welded, round bar 9, which extends transversely to the longitudinal direction of the side legs 3, 4 and extends transversely to the plane in which the two side legs 3, 4 are located. The round bar 9 preferably protrudes from the inner space of the side legs 3, 4 with pieces that are of equal length and preferably also comprises a structural steel wire piece with, for example, a slightly larger diameter in relation to the diameter of the structural steel wire piece 2. The structural steel wire piece 2 comprises for example a diameter of 6 mm and the round rod 9 a diameter of 10 mm. The end element 8 or the round bar 9 can also be, for example, a longitudinal bar of a reinforcement, for example of a reinforcement mat, wherein more than one longitudinal bar can also be attached between the legs 3, 4 (not shown).
    Figure 6 comprises variants of the end element 8 according to the invention.
    At least one end region 15 of a side leg 3, 4 is herein preferably rectangular, preferably bent transversely to the plane of the side legs 3, 4. It can be seen from Figure 6 that both end regions 15 are deflected in the opposite direction. Both end regions 15 can, however, also be bent, for example, parallel to one another, extending horizontally (not shown).
    The deflected end regions 15 or both deflected end regions 15 may comprise at least one further bend. In Figure 7, for example, such further bends are shown in a top view on the transport anchor and only at an end region of a side leg. However, the bends can also be identical or different in the end region of the other side leg. Accordingly, L-shaped bends (Figure 7a), U-shaped bends (Figure 7b), triangular bends (Figure 7c) or wave-shaped bends (Figure 7d) are effective.
    In the area below the trailer loop 6, for fixing to the longitudinal and / or transverse bars in a cage reinforcement, both side legs 3, 4 may be fastened to, for example, welded, which for example has the same diameter as the structural steel wire in a cage reinforcement. of the side legs 3, 4 or which is advantageously slightly thinner and has, for example, a diameter of 5 mm. The length of the fixing rod 10 can approximately correspond to the length of the end element 8 or correspond to the end rod 9 and is, for example, 100 mm; which length depends, for example, on the width of the cage reinforcement which is arranged in the transport anchor, or on account of the thickness of the structural part / plate in which the cage reinforcement is provided, respectively.
    The fastening rod 10 also extends transversely to the longitudinal direction of the side legs 3, 4, but for example parallel to the plane of the side legs 3, 4. The fastening rod 10 is even arranged in the embedding area of the transport anchor 1 or within the reinforced structural body and increases the torsional stiffness of the transport anchor, in particular through the fastening positions on the side legs 3, 4, while the area of the suspension loops, on the other hand, may not be provided protrudingly with respect to the construction body for projecting out of the construction body provided with the transport anchor.
    Figures 4 and 5 show the transport anchor 1 according to the invention embedded in a cage reinforcement 14 for a porous concrete body. The cage reinforcement 14 is made of structural steel wires and comprises, for example, longitudinal bars 11 and cross bars 12 as well as spacer bars 13 between the cross bars 12 and / or longitudinal bars 11.
    The transport anchor 1 is deployed in the cage reinforcement 14, so that the end bar 9 is situated, for example, in the lower region of the cage mat 14, for example in the transverse center and extends parallel to the longitudinal direction of the longitudinal bar 11 or the cage reinforcement 14. With the fastening connection 10 the transport anchor 1 is attached to two longitudinal bars 11 and / or to two transverse bars 12 of the cage reinforcement, for example welded (Fig. 4).
    The transport anchor 1 according to the invention comprises a number of variable properties. In the manufacture thereof, for example, the following properties can be chosen: - the length and thickness of the fixing rod 10, - the length and thickness of the end element, for example the end rod 9, - the arrangement position of the fixing rod 10 on the anchor element, for example the distance from the loop 6, - the position of the end bar 9 on the anchor element, for example the distance from the ends 7, - the diameter of the structural steel wire in question, - the distance from the side legs 3, 4 relative to each other, - the position of the transport anchor 1 in the cage reinforcement 14.
    The manufacture of a transport anchor according to the invention can, for example, take place with the aid of machines on which reinforcing steel rods, reinforcing steel mats or steel carbon mats are produced automatically, because the same work operations such as cutting, bending and welding are actually required for this.
    The length of a transport anchor 1 from the base 5 to the end 7 is, for example, 500 mm, the fixing rod 10 being arranged above the center in the longitudinal direction and the end element 8 below the center of the longitudinal direction of the side legs 3, 4. Transport anchors according to the invention are suspended, for example, in cage reinforcements 14 which have a length of approximately 6000 mm, a height of 750 mm and a width of 100 mm.
    The invention also relates to the attached arrangement of a transport anchor according to the invention to a cage reinforcement. Accordingly, an object of the invention is also a corresponding reinforcing body with transport anchors according to the invention disposed thereon.
    The subject of the invention is also a structural body, in particular of porous concrete, in which a transport anchor according to the invention is arranged, for example in combination with a cage reinforcement and from which the U-base 5 can be accessed from outside as a suspension loop, for example from a bowl protrudes from the structural body.
