TRANSPORT ANCHOR HAVING A FIBRE-PLASTIC COMPOSITE MATERIAL PRESSURE ELEMENT

Abstract

A transport anchor for double walls, includes a bow-shaped basic body, having an arcuate central portion for suspending slinging components, two anchor legs which emanate from the central portion and extend substantially parallel to one another, and a pressure element which is arranged between the anchor legs. The pressure element is formed from a fibre-plastic composite material and has, at its two ends, end caps which are placed by their open side onto free ends of the cylindrical pressure element and which each have openings through each of which an anchor leg extends.

[0034] The invention will be explained in more detail based on the following figures. These show various embodiments of a transport anchor according to the invention, wherein additional forms are conceivable. Shown on:

[0035] FIG. 1: is a perspective view of a first embodiment variant of a transport anchor according to the invention with a base body made out of steel,

[0036] FIG. 2: are two perspective views of a second embodiment variant of a transport anchor according to the invention with a base body made out of a steel rope,

[0037] FIG. 3: is a magnified view of an end cap with introduced steel rope,

[0038] FIG. 4: is a top view of the transport anchor on FIG. 2 in transport state 3,

[0039] FIG. 5: is a transport anchor according to the invention with cross sectional reinforcements,

[0040] FIG. 6: is a perspective view of a transport anchor according to the invention with a fixing element.

[0041] FIGS. 1 to 6 show different variants of a transport anchor 20. The depicted figures or embodiments serve an explanatory purpose; individual features of the individual exemplary embodiments can be combined with features of other exemplary embodiments as desired.

[0042] The transport anchor 20 has a base body 22 with an arcuate central portion 24 and adjoining anchor legs 26 that run parallel to each other. Further shown is a pressure element 28 arranged between the anchor legs 26.

[0043] According to the invention, the base body preferably consists of steel, a steel rope or a rope made out of another resistant, suitable material. The pressure element 28 is comprised of a fiber-plastic composite material.

[0044] According to the invention, the pressure element 28 can be arranged at various locations in the progression of the base body. FIGS. 1 and 2 exemplarily show a possible position, specifically adjacent to a transitional area between the anchor legs 26 and the arcuate central portion 24. Alternatively, the pressure element 28 can be arranged in the transitional area, with a larger distance to the transitional area 30, or also within the arcuate central section 24.

[0045] The arcuate central portion 24 can have an essentially triangular shape, comprised of two straight leg sections 32 that transition into a relatively narrow arc 34. For example, this is the case for a base body 22 made out of steel or steel wire (FIG. 1). Alternatively thereto, the arcuate central portion 24 can also be arc-shaped in design as a whole, in particular when using a steel rope (FIG. 2).

[0046] The free ends of the pressure element 28 are adjoined by the end caps 62 with openings 52 for poking through the anchor legs 26 on the end side. In the depicted exemplary embodiment, the end caps 62 are essentially tubular in design, and one of their open sides is plugged onto the ends of the pressure element 28. Because the inner diameters of the end caps 62 are smaller than the outer diameters of the pressure element 28, the end caps 62 have to be pushed or pressed onto the pressure element 28. They widen as a result, and are fixedly and immovably retained on the pressure element 28 after assembly owing to their elasticity.

[0047] In the exemplary embodiment shown, the openings 52 through which the anchor legs 26 extend are arranged precisely opposite each other, so that the anchor legs 26 run parallel to each other and essentially at a right angle to the main extension of the pressure element 28. Alternatively, however, the openings 52 can also be arranged slanted or offset to each other, so that the anchor legs 26 are guided through the end caps 62 at an angle, and do not run parallel to each other further on.

[0048] FIG. 3 shows a magnified view of an end cap 62 with a steel rope introduced through the openings 52. The advantage to designing the end caps 62 as a tubular section is that liquid concrete can penetrate from outside into the component to be transported through the opened free end of the end cap 62 while casting the transport anchor, which improves the subsequent stability and tensile strength of the overall construction. The pressure element 28 can have a respective groove at its two free end faces, in which the legs come to lie.

[0049] FIG. 4 shows the transport anchor on FIG. 2 in a transport state. As evident, using the steel rope advantageously makes it possible to roll up the latter and temporarily fix it in place for transport or packaging with the help of fastening means 60. Shown are retaining clips that can be pressed onto the steel rope. Alternatively, however, fastening means 60 can also be made out of a different material, for example out of wire or steel.

[0050] On the one hand, the anchor legs 26 can be conical or tapered in design at their free ends; however, their free ends can also be provided with cross sectional reinforcements 36 (see FIG. 5). The cross sectional reinforcements 36 can consist of the same material as the base body 22, but can also be made out other materials. Shown is the use of a base body 22 consisting of a steel rope; of course, the cross sectional reinforcements 36 can also be combined with a base body comprised of steel or steel wire.

[0051] FIG. 6 shows a fixing element 48 that runs essentially parallel to the pressure element 28, and holds the two anchor legs 26 in their position or pretensioned relative to each other. Fixing elements 48 make sense in particular when using a base body 22 comprised of steel or steel wire. Connecting, preferably welding, the fixing element 48 with the two anchor legs 26 makes it possible to additionally reduce the overall length of the anchor legs 16.

[0052] The embodiment variants depicted on FIGS. 1 to 6 with the pressure element 28 comprised of a fiber-plastic composite material can alternatively also be modified so as to have the pressure element 28 consist of steel. The depicted advantages can also be applied to such an embodiment variant.

[0053] The end caps 62 are especially advantageously made out of a plastic. This makes it especially easy to press the pressure element 28, anchor leg 26 and end cap 62 elements with each other.

[0054] The figures show various advantageous embodiment variants of the invention. The shown combinations are not to be regarded as conclusive; rather, they can be combined with each other in any manner desired.
