Description

Technical field

The invention relates to the use of a storage box for embedding retaining strap elements in concrete.

State of the art

From EP 2 110 486 A2 is known a lift assembly anchor which can be embedded in the concrete roof of a lift shaft for attaching assembly platforms for the assembly or maintenance of lifts.

Also, from the applicant’s EP 1 589 156 B1 is known a connecting element for the connection in transverse force-locking relationship of precast concrete components at a joint with transverse forces parallel to the longitudinal direction of the joint, in which at least two reinforcing loop elements are accommodated in a storage box, the through-openings for two reinforcing loop elements being provided near opposite ends of the storage box. The connecting element is in this case designed so that each reinforcing loop element takes up substantially equal forces, that is, is subjected substantially equally to both transverse and longitudinal forces.

The applicant found, however, that to some extent different demands are made on the reinforcing loop elements in order to improve the flexibility of using them.

Account of the invention

It is the object of the invention to provide a use of a storage box which solves the known problems from the state of the art, and is also suitable for taking up loads safely, in particular to prevent twisting, according to requirements. The object is achieved by the use of a storage box according to claim 1. Preferred embodiments of the use of a storage box according to the invention are apparent from the subsidiary claims.

The advantages of the invention result from using a storage box having at least two retaining strap elements for embedding in concrete and attaching a lift cage element or lift assembly apparatus in a lift shaft, in particular a lift shaft for (goods) lifts used on building sites. By using this it is possible to attach lift cage elements, whether directly and/or using a pulley-driven guide mechanism or the like, to the retaining strap elements. In this way advantageously a particularly safe fixing device is provided for a lift cage element or a lift assembly apparatus with optimum use of space, because it is not necessary to use additional elements such as a T-beam or I-beam beneath the roof of the lift shaft in order to support the lift cage element or lift assembly apparatus. A "storage box" within the meaning of the invention is in this case any approximately box-shaped object which can be embedded in concrete and has essentially at least one opening through which the two retaining strap elements can be bent out.

Also, a "retaining strap element" is a loop which can be accommodated in the storage box and anchored in the concrete by means of an anchor element projecting from the storage box and which is preferably suited to taking up traction forces. In this connection the disclosure of the applicant's above-mentioned document with regard to the details of the storage box is made the subject of the present invention.

According to a preferred embodiment, a retaining strap element of the storage box is additionally used to prevent twisting of a lift cage element or lift assembly apparatus. In this way, according to an embodiment of the invention, it is possible in a particularly advantageous manner to give a storage box a completely new and revised function.

According to a preferred embodiment, one retaining strap element of the storage box is used to secure persons and/or objects. In this way, with the storage box according to the invention particularly advantageously persons and/or objects which are in a lift shaft can be protected against falling with their own retaining strap element. In this way the risk of an accident is greatly lowered, and the possibility of using the storage box is greatly improved.

The embodiment according to claim 4 is based on the concept of designing individual components according to their load requirement profile in such a way that they can be used optimally. In this case it is also an aim to save materials.

Accordingly the storage box for embedding retaining strap elements in concrete by means of anchor elements comprises at least one first retaining strap element and at least one second retaining strap element, wherein the first retaining strap element is formed from a cable element of longer length and/or is suitable for taking up greater forces than the second retaining strap element.

With the storage box, it is possible advantageously to take up particularly high forces, in particular traction forces, with the first retaining strap element, and to take up lower forces with the second retaining strap element. In order to clarify this difference for the operator in a way which is easy to see, the first retaining strap element, that is, the retaining strap element which is suitable for taking up higher forces, can be designed with a longer length. Furthermore, in this way it is possible to assign a main function to the first retaining strap element such as supporting a lift cage or supporting a lift assembly apparatus, and assign an ancillary or controlling function to the second retaining strap element such as an alignment function or prevention of twisting. Also, the second retaining strap element can particularly advantageously be assigned a securing function, such as preventing a person and/or property from falling. In this case the support of a lift cage or lift assembly apparatus requires substantially more traction or lifting force than the alignment of the same components or securing lift fitters and their equipment or other objects. In this way particularly advantageously it is possible to design the two retaining strap elements according to their requirements. Furthermore, designing the retaining strap elements according to requirements saves weight and therefore material costs.

According to one embodiment the first retaining strap element and/or the second retaining strap element is marked differently in comparison with the other retaining strap element. Different inks and/or different inscriptions are particularly suitable for this, wherein the different inscriptions can be made directly on the retaining strap element and/or using labels which can be affixed and which, if necessary, are also coloured. In this way particularly advantageously it is possible to mark the different retaining strap elements in each case in such a way that an operator selects the right retaining strap element according to the respective requirements. The coloured marking saves additional reading, with the result that, with frequent use of the storage box according to the invention, time can be saved.

According to a further preferred embodiment, the storage box is additionally provided with a metal clip which is designed in such a way that the two retaining strap elements can be held in the storage box. In this way it is possible to mount the retaining strap elements in a position particularly favourable to transport of the storage box and in a position particularly favourable for embedding in concrete. The cavity of the storage box which accommodates the retaining strap elements can additionally be covered with adhesive tape.

According to a further preferred embodiment, the retaining strap elements are designed in such a way that they can be folded into the storage box when not needed and folded out of it when needed. In this way particularly advantageously it is possible to design the retaining strap elements in such a way that they can be folded out or bent out only according to requirements. Thus they can be folded out for example when the lift assembly apparatus is used and then, that is, after use, folded back in. In this way particularly advantageously space in the lift shaft can be saved.

According to a further, particularly preferred embodiment a first, preferably rigid anchor element is provided for the first retaining strap element and a second, preferably rigid anchor element for the second retaining strap element, wherein the anchor elements are in each case formed on the side of the storage box opposite the retaining strap elements, a rear side of the box. In this way particularly good anchoring of the anchor elements in the concrete is made possible, as the anchor elements do not change position during the concreting operation and as the anchor elements are likewise graded according to the design of the retaining strap elements in order to be able to take up the corresponding different forces.

The storage box may further be profiled at least in one section with recesses and/or projections. In this way, particularly good and reliable anchoring of the storage box when embedded in concrete can be ensured.

According to a further, particularly preferred embodiment the first retaining strap element is designed to take up permitted traction forces of at least 1000 kg and the second retaining strap element is designed to take up permitted traction forces of at least 100 kg. In this way use of the storage box which is advantageous with respect to weight is made possible. The two retaining strap elements can therefore be made more cheaply according to their respective requirements, which makes the overall construction more economical.

According to a further, particularly preferred embodiment the storage box is designed so that it can be embedded in a concrete component in such a way that an opening in the storage box from which the retaining strap elements can be bent out is substantially flush with the surface of the concrete component. In this way particularly advantageously it is possible to manufacture an easy-to-use precast concrete component or cast-in-situ concrete component which has no protruding surfaces on the outside, which often pose a risk of injury.

Furthermore, it is possible to form a marking area, in particular an inscription area, inside the storage box in such a way that it is visible from the side of the retaining strap elements and not from the side of the anchor elements. In this way an operator, in particular a lift fitter, can particularly advantageously read the properties of the storage box.

Detailed description of a preferred embodiment of the invention

The invention is described below with reference to Figures 1 and 2 with the aid of an embodiment by way of example.

The invention relates to a storage box for embedding retaining strap elements in concrete by means of anchor elements. The storage box 10 according to the invention is preferably suitable for being installed in the uppermost section, in particular the roof, of a lift shaft.

The storage box 10 is in this case a substantially rectangular, preferably elongate box, comprising a rear side 16 and, disposed on the latter, four side surfaces 17-20. On the side of the storage box opposite the rear side, an opening is formed.

Retaining strap elements 12, 14 are accommodated in the storage box 10, wherein the retaining strap elements 12, 14 are in each case additionally attached to anchor elements 22, 24. The loops of the retaining strap elements 12, 14 here preferably extend approximately into the region of the rear side 16, and there end in each case in the anchor elements 22, 24 in which they are additionally fixed.

The straps 12, 14 have different strap lengths and preferably also different cable diameters. In this case strap 12 is longer than strap 14 and is also capable of taking a greater load than strap 14. The anchor elements 22, 24 of the straps 12, 14 are also designed according to their load-carrying capacity, so that the anchor element 22 of strap 12 is larger and can take a greater load than the anchor element 24 of strap 14.

To ensure that the straps 12, 14 are each loaded only according to their requirements, the straps are firstly either marked in colour, at least in one section, and/or they are secondly also provided with a label or some other kind of inscription, so that it is easy to see their intended purpose from the outside. In this way it is possible to prevent the straps from being loaded or used wrongly during assembly.

In addition a marking area, in particular an inscription area, can be provided inside the storage box, so that in this way too the type and properties of the storage box as well as of the different retaining strap elements can be read.

As Figure 2 shows, the straps 12, 14 are capable of swivelling in such a way that they can be swivelled into the storage box 10 and held in the storage box during transport by means of a releasable clip 30, in particular a metal clip 30. In addition a covering strip can be provided, in particular a tape, which seals the opening in the storage box during transport and additionally when it is embedded in concrete, so that no concrete runs into the storage box 10 while it is being embedded in concrete. Hence it is possible for the retaining strap elements 12, 14 to be folded into the storage box 10 when they are not needed and held there for example by means of the covering strip or the clip 30, and folded out again when needed.

The retaining strap elements are in this case preferably designed in such a way that the first retaining strap element 12 can preferably take a load of at least 1000 kg, and the second retaining strap element 14 can preferably take a load of at least 100 kg. In this way it is possible to attach for example a lift cage element and/or a lift assembly apparatus to the first retaining strap element 12 and therefore take up the load caused by the weight of the lift cage element or lift assembly apparatus with the first retaining strap element 12. The second retaining strap element 14 can then be used additionally to prevent twisting, so that twisting of the lift cage element or lift assembly apparatus in the shaft is prevented. This is possible in particular on account of the resulting lever action between the two retaining strap elements 12, 14. Furthermore, the second retaining strap element 14 can be used particularly advantageously to secure persons or objects.
