Definitions
- the invention relates to a method for producing such a transport anchor.
- Such transport and installation anchors are used for the transport of so-called double walls. They are usually poured into the precast concrete industry in concrete walls and serve on the one hand as a transport device to the stop means can be hung, on the other hand as a spacer during the concreting process.
- the pressure element is formed of steel and welded onto the anchor legs.
- the mentioned large forces act on the transport of the double walls on this weakened area, whereby the risk of tearing of the welds, and thus the subsequent excessive deformation of the lifting anchor is very high.
- a similar pressure element made of steel goes from the publication EP 3 029 220 A1 out.
- the pressure element is preferably used by spot welding. The welding process also locally changes and weakens the surrounding material, which also reduces stability. In both cases, the welded joints can break out lead the transport anchor from the concrete, which in turn can cause the crash of the precast concrete part.
- transport anchors which instead of a pressure element not made of steel, but of a resilient material, such as wood.
- Wood is able to absorb the forces that occur, but does not detach itself from the anchor legs.
- the disadvantage is that wood can absorb liquid, which leads to a rotting of the printing element on the one hand, but can also freeze and expand on the other hand. Both is disadvantageous because then in the aftermath still damage in the double wall or the precast concrete part can be adjusted.
- the object of the invention is to provide a lifting anchor, which does not have the above-mentioned disadvantages.
- the transport anchor should still be inexpensive to produce and enable safe use. Furthermore, the transport anchor should not lead to damage or disadvantages even if it remains in the double wall later.
- the object is further to propose a method for producing such a transport anchor.
- the object of the invention is achieved in that the pressure element consists of a castable curing material.
- An inventive method for issuing such a transport anchor results from the independent method claim.
- the pressure element according to the invention is poured individually and adapted to the transport anchor to be manufactured.
- Castable materials are understood as meaning those which, on curing, change from a liquid or pasty phase into a solid phase.
- offer the use of concrete since then the pressure element is made of the same material as the double walls, in which it is cast.
- the invention will be explained by way of example for the use of concrete as a production material for the pressure element.
- the pressure element is connected in the same way with the anchor legs, as well as the double walls themselves.
- This has the advantage that occurring forces act equally and be distributed.
- a very stiff steel or even a pressure element made of wood there are no deviating conditions in the transition region between the armature legs and the pressure element.
- the use of steel or wood pressure elements causes a very rigid and stiff behavior in this transition region, which in turn can lead to compensating movements of the armature legs and thus to a detachment from the double walls.
- the local welding-induced local change in the weld area and the breaking of welds is usually excluded.
- the pressure element of concrete according to the invention is also waterproof, a transition of moisture through the pressure element from a double wall to the other is thus prevented. This is not the case in particular with pressure elements made of wood and with tubular, inside hollow pressure elements made of steel.
- the pressure element may have any desired cross-section, in particular round, oval, right-angled or triangular cross-sections are suitable.
- the pressure element may be made entirely of concrete, but it may also be offset with a reinforcing material. For example, corresponding fibers, nets or other elements of steel or a tensile alternative material may be provided.
- the pressure element can be arranged in the region of the transport anchor, in which the anchor legs extend substantially parallel to each other.
- the pressure element can also be arranged in a transition region between the arcuate central section and the anchor legs extending parallel to one another.
- the central portion may be formed by two straight, mutually running leg portions which are connected to each other via a relatively short arc.
- the central portion has a total of approximately a triangular Shape up.
- the arcuate base body can also run curved over its entire length.
- the anchor legs may be made straight over their entire length, but alternatively they may also have free end portions formed from the otherwise straight extension of the anchor legs.
- the deformation can take place in all directions, for example, toward each other, away from each other, or parallel to each other, or in different directions.
- the main body is usually formed of steel. According to the invention, however, this can also consist of a wire or wire rope. It is preferable to use a stainless steel cable, such as a galvanized steel cable, but it is also conceivable to use a sufficiently strong rope, such as Kevlar or carbon.
- a cable or rope makes manufacturing easier and faster due to its flexibility. Since a wire or steel cable consists of a plurality of strands or wires, the use of the transport anchor according to the invention is safer. Usually not all strands break at the same time, but individually, so that there is often time left to settle the double walls before the rope breaks completely.
- the pressure element may have a length which does not protrude beyond a maximum width of the base body.
- the pressure element is thus arranged between the two anchor legs.
- the pressure element can have grooves at its two free ends, through which in each case an armature leg extends.
- the pressure element may have a length which exceeds the maximum width of the base body. In this case, therefore, the free ends of the pressure element protrude laterally beyond the base body.
- the pressure element can each anchor leg a have through opening, through which the respective armature leg extends through, alternatively, correspondingly deep grooves are conceivable.
- the openings for the passage of the main body or the anchor legs can be oblique or offset from each other, so that the armature legs are passed at an angle through the pressure element and not parallel to each other. In the direction of their free ends, the distance of the two armature legs increases towards each other.
- the base body is formed by a flexible steel cable.
- the arcuate central portion deforms above the pressure element during lifting of the component to be transported. The arcuate central section is stretched. Under load, the armature legs thus run straight through the pressure element due to the oblique openings.
- the pressure element is either stationary, so immovably connected to the body, but it can also be provided that this along the armature leg at least to each other.
- the main body of a transport anchor according to the invention can preferably be shortened by the fact that the free ends have cross-sectional reinforcements, for example in the form of pipe sections or cylindrical bodies. As a result, the connection of the main body or the armature leg is improved with the respective double wall.
- the cross-sectional reinforcements can also be made of a different material.
- a fixedly connected or removable fixing element which runs approximately parallel to the pressure element.
- This can also be made of steel, but also made of plastic or other suitable material.
- the free ends of the anchor legs taper. This facilitates the insertion of the anchors in the double walls, especially if they have a Stahlbe intersectrung.
- the pressure element in its course on a separating body, which divides the pressure element, so to speak, into two areas.
- This separating element can cause a thermal decoupling, which in turn is advantageous for the durability of the transport anchor, in particular after installation of the double walls.
- the separator is made of a material that is able to absorb the high forces. In particular, for example, offers a disk of a correspondingly resistant plastic, which has a low thermal conductivity.
- the preparation of a transport anchor according to the invention may preferably be carried out in that the pressure element is first prefabricated and then connected to the base body.
- the method step of manufacturing the printing element can also be combined with the assembly with the base body.
- the pressure element is manufactured, arranged in the base body and fixed with this.
- the production of the printing element can be done with the help of a losierbaren and a captive form.
- the shape can be made in several parts or in one piece.
- the pressure element can preferably be produced by filling a tubular, cylindrical basic shape with concrete. After curing of the concrete, the basic shape, which consists for example of plastic, remain on the pressure element. Even before filling with concrete, the basic shape is preferably connected to the main body or with the anchor legs. This method is quick and easy, but has the disadvantage that when filling or pouring the basic form liquid concrete material can flow through the openings for the body. This is particularly due to the fact that the openings must have a slightly larger diameter than the anchor legs.
- the cylindrical basic shape is made in several parts. To a cylindrical base body close to the end of each cover elements with openings for the passage of the anchor legs.
- the cover elements are substantially cup-shaped and are attached with their open side to the ends of the cylindrical base body.
- the free end surfaces of the cylindrical base body can be made parallel to each other and arranged, but they can also run obliquely to each other.
- the plug-in cover elements also have inclined surfaces on their side facing the base body, so that in the assembled state of the three elements a consistently straight shape results.
- the openings for the passage of the main body or the anchor legs are arranged obliquely or offset from one another, so that the armature legs are passed at an angle through the pressure element and not parallel to each other.
- the invention relates to the use of concrete, but in principle also other materials can be used, which consist of concrete according to a material that passes from a liquid or wet phase into a solid phase.
- FIGS. 1 to 20 show different variants of a transport anchor 20.
- This has a main body with an arcuate central portion 24 and adjoining, mutually parallel armature legs 26. Furthermore, a pressure element 28 arranged between the armature legs 26 is shown.
- FIGS. 1 and 2 illustrate further that a length L of the pressure element 28 in the illustrated embodiment exceeds a minimum width B of the transport armature 20 and the body.
- the pressure element 28 may also be designed such that it does not exceed the width B of the transporter 20.
- the base body is preferably made of steel, a steel cable or a rope of another resistant, suitable material.
- the pressure element 28 is formed of concrete.
- the pressure element 28 may be arranged according to the invention at different points in the course of the body.
- the Figures 1 and 2 show exemplary two positioning possibilities, namely in a transition region 30 between the armature legs 26 and the arcuate central portion, or between the mutually parallel armature legs 26. Regardless of the embodiments shown, the pressure element 28 may also be at a greater distance to the transition region 30 between the armature legs 26 or be arranged within the arcuate central portion 24.
- the arcuate central portion 24 may have a substantially triangular shape formed by two straight leg portions 32 which merge into a relatively narrow arc 34. Alternatively, the arcuate central portion 24 may also be performed overall arcuate, such as in the FIGS. 3 to 6 shown.
- the armature legs 26 may be performed conically or tapered at one end at their free ends, but also cross-sectional reinforcements 36 may be provided at the free ends.
- the FIGS. 5 to 12 show various embodiments of such cross-sectional reinforcements 36 in combination with different arcuate central sections 24. It is explicitly noted that further combinations are conceivable and useful.
- the cross-sectional reinforcements 36 may be made of the same material as the main body, but they may also be made of other materials.
- FIGS. 13 and 14 illustrate a particularly advantageous embodiment of the invention.
- a separating body 38 is provided, which divides the pressure element 28 into two separate regions, a first pressure element section 40 and a second pressure element section 42.
- the separating body 38 serves in particular for the thermal decoupling of the two pressure element sections 40, 42. This effectively prevents an undesired cold bridge between the two double walls.
- FIGS. 15 and 16 the use of a reinforcing element within the pressure element 28.
- the wire body 46 reinforced on the one hand the pressure element 28, but also causes a better attachment to the armature leg 26.
- the pressure element 28 may have further elements for reinforcement, such as braids, fibers made of steel or plastic.
- FIGS. 17 and 18 show a fixing element 48 which extends substantially parallel to the pressure element 28 and the two armature legs 26 in their position or this under bias to each other.
- a fixing element 48 which extends substantially parallel to the pressure element 28 and the two armature legs 26 in their position or this under bias to each other.
- FIGS. 19 and 20 a variant in which the free ends of the armature legs 26 are formed out of the substantially straight extending direction of the armature legs 26.
- the armature legs 26 each have an end section 50 extending transversely to the actual course of the armature legs.
- the end sections 50 extend at right angles in different directions, but alternatively they can also taper towards one another or at other angles away from the armature legs 26.
- FIG. 21 shows a further advantageous embodiment of the invention.
- the pressure element 28 is formed in a basic shape, which is designed in three parts.
- the basic shape is filled with concrete and remains on the transport anchor 20, it has a base body 60 and two cover elements 62.
- the cover members 62 close with openings 52 for the passage of the armature legs 26 at the end.
- the cover elements 62 are designed essentially cup-shaped and are attached with their open side to the ends of the cylindrical base body 60.
- the free end surfaces of the cylindrical base body 60 extend in the embodiment shown at an angle to each other.
- the plug-in cover elements 62 also have inclined surfaces on their side facing the base body 60, so that in the assembled state of the three elements 60, 62 a consistently straight shape results.
- the openings 52 through which the anchor legs 26 extend obliquely or offset from each other, so that the armature legs 26 are passed at an angle through the pressure element 28 and not parallel to each other.
- the base body is formed of a steel cable.
- the armature legs 26 extend through openings 52 of the respective pressure element 28.
- end-shaped grooves (not shown) to be provided.
