Description

[0001] The invention relates to a holding element with an eyelet and an elongated, preferably cylindrical, base body and a stop element.

[0002] When loading large and bulky loads, such as concrete formwork elements from trucks, straps and bands are often used that are stretched around the formwork elements. However, unwanted slipping of the straps and bands is not reliably prevented, which repeatedly leads to accidents at work. Abrasion also causes significant wear and tear on the straps and bands, which is why they have to be replaced frequently. When lifting straight-faced or pre-bent formwork elements with straps and bands, unwanted bending of the formwork elements often occurs. In addition to the straps and bands mentioned, holding elements are known that have an eyelet and a base plate, with the eyelet and base plate being connected to one another via a base body. These holding elements, such as safety bolts, are often designed in several parts, with a safety split pin, for example, being inserted through the eyelet.This has the disadvantage that the locking pin is often lost and needs to be replaced.

[0003] The object of the present invention is to improve the described holding elements.

[0004] This object is achieved according to the invention by the features of claim 1.

[0005] The holding element according to the invention with the features described above is therefore particularly characterized in that a lateral extension of the stop element is greater in at least two mutually transverse directions than the lateral extension of the base body. The holding element can be used, for example, to load concrete formwork elements. For this purpose, a carrier with a receptacle is attached to the concrete formwork elements, through which the holding element can be inserted from below. For lifting, a hook can be hooked into the eyelet of the holding element. The stop element of the holding element prevents the holding element from being completely inserted through the receptacle of the carrier. During lifting, a tension is exerted on the holding element and transferred via the stop element to the carrier, resulting in the lifting of the concrete formwork element.The holding element can be designed as a single piece, thus eliminating the need for individual parts that can be lost.

[0006] In an advantageous embodiment, the eyelet is formed in an extension of the base body. This can, for example, make it possible for the eyelet to have a larger diameter than the base body, creating enough space to accommodate large hooks.

[0007] In an advantageous embodiment, it is provided that the eyelet has a preferably first lateral extension which corresponds to the lateral extension of the base body. This can, for example, make it possible for the extension and the base body to have the same dimensions in one direction and, for example, to be inserted into a receptacle that also has the same dimensions. Alternatively or additionally, it is provided that a preferably second lateral extension of the eyelet is greater than a lateral extension of the base body. This can, for example, make it possible for the eyelet and stop element to be inserted into a receptacle that has the extension of the base body in one direction and a greater extension in another direction. By rotating the holding element by, for example, 90°, an undesired falling out of the holding element can be prevented.

[0008] In an advantageous embodiment, the eyelet is tightly closed all the way around. This can, for example, prevent a hook inserted into the eyelet from being moved through an opening in the eyelet's perimeter.

[0009] In an advantageous embodiment, the stop element is a base plate. This can, for example, ensure that a support to be lifted rests evenly on a flat surface of the base plate. In particular, the stop element can be a round base plate. This can, for example, ensure that the holding element cannot fall through a receptacle or opening that is smaller in diameter than the base plate.

[0010] In an advantageous embodiment, the underside of the eyelet is parallel to the top side of the base plate. This can, for example, ensure that tensile or compressive stress on the retaining element is applied evenly to the underside of the eyelet and the top side of the base plate.

[0011] In an advantageous embodiment, the eyelet has a preferably round engagement area. This can, for example, ensure that the tensile load of a hook inserted into the eyelet is evenly distributed across the eyelet. This has a positive effect on the service life of the retaining element.

[0012] In an advantageous embodiment, the stop element has a diameter that is larger than the maximum extension of the eyelet. This can, for example, make it possible for the stop element to limit the insertion of the retaining element into a receptacle that corresponds in a direction to the maximum extension of the eyelet. The retaining element can thus be inserted into such a receptacle with the eyelet first, but no further than the stop element.

[0013] In an advantageous embodiment, the retaining element is formed in one piece. This makes it possible, for example, to achieve a retaining element without additional loose parts. Furthermore, the stability of the retaining element, for example, the tensile, compressive, shear, bending, and torsional loads, is greater than that of known, multi-part retaining elements. The described retaining element is preferably solid and made of steel or cast iron.

[0014] To achieve the aforementioned object, the invention further proposes the use of a holding element for connecting a formwork to a lifting device. In this application, a holding element according to the invention is attached to a formwork, for example, a concrete formwork element, and lifted by means of a lifting device, which is constructed, for example, from several hooks and chains. This can, for example, enable safe and rapid loading of formwork.

[0015] To achieve the aforementioned object, the invention further proposes the use of a retaining element, wherein the retaining element is inserted, in particular pushed through, into a receptacle in a designated pulling direction. This can, for example, ensure that the retaining element is secured against slipping through the receptacle in the designated pulling direction.

[0016] The invention will now be described in more detail using exemplary embodiments, but is not limited to the exemplary embodiments. Further exemplary embodiments arise from combining the features of one or more claims with one another and / or with one or more features of the exemplary embodiments.

[0017] It shows: Fig. 1 a holding element in three-dimensional view, Fig. 2 the retaining element Fig. 1 and a carrier in three-dimensional view, Fig. 3 the retaining element is inserted into the carrier Fig. 2 in three-dimensional view, Fig. 4 the holding element inserted into the carrier and rotated by 90° in three-dimensional view, Fig. 5 the holding element and the carrier in side view, Fig. 6 the retaining element inserted into the carrier in side view and Fig. 7 a holding device with holding element and a concrete formwork.

[0018] Fig. 1 shows the holding element 1 according to the invention. The holding element 1 has an eyelet 2 and an elongated, cylindrical base body 3 with a stop element 22. The stop element 22 is designed as a round base plate 4.

[0019] A lateral extension 5 of the base plate 4 is greater in at least two mutually transverse directions than a lateral extension 6 of the base body 3. The eyelet 2 and the base plate 4 are arranged at opposite ends of the holding element 1. The base body 3 has an extension 7 at one end, in which the eyelet 2 is formed. A surface 8 of the extension 7 is flat on one side, so that the extension 7 can rest flatly with this surface on a surface of a support 9. On a side of the extension 7 opposite the flat side, the extension 7 is rounded.

[0020] The eyelet 2 has a first lateral extension 10 that approximately corresponds to the lateral extension 6 of the base body 3. Furthermore, the eyelet 2 has a second lateral extension 11 that is larger than the lateral extension 6 of the base body 3. The base plate 4 is round.

[0021] In Fig. Figure 2 shows how the holding element 1 is inserted into a support 9 from below in a designated pulling direction 21. The support 9 has a receptacle 12 with a width B, a height H, and a depth T, through which the holding element 1 is passed. The width B of the receptacle 12 corresponds at least to the second lateral extension 11 of the base body. The height H of the receptacle 12 corresponds at most to the length L of the base body 3, measured from a top side 17 of the base plate 4 to a bottom side 16 of the extension 7, the surface 8. The depth T corresponds at least to the first lateral extension 10 of the base body 3 and the lateral extension 6 of the base body 3, and at most to the second lateral extension 11 of the base body 3.

[0022] The Fig. Figure 3 shows the retaining element 1 inserted into the carrier 9. The round base plate 4 is dimensioned such that it cannot be guided through the receptacle 12, thus limiting the insertion of the retaining element 1. If an upward pull is now exerted on the retaining element 1, it cannot be moved through the receptacle 12 because the base plate 4 abuts the carrier 9 and blocks movement. Since the base plate 4 is round, it is ensured that the retaining element 1 cannot be moved upward through the receptacle 12, even if the retaining element 1 is twisted.

[0023] Fig. Figure 4 shows the retaining element 1 rotated 90° around its longitudinal axis. In this position, if the retaining element 1 is pulled downward, it is ensured that the retaining element 1 cannot be moved downward by the receptacle 12, since the surface 8 of the extension 7 rests on the support 9 and blocks the movement.

[0024] A side view of the holding element 1 and the carrier 9 is shown in Fig. 5. It can be seen that the length L of the holding element 1, measured from the top side 17 of the base plate 4 to the bottom side 16 of the extension 7, must be at least as long as the height H of the carrier 9 so that the holding element 1 can be rotated in its holding position. The bottom side 16 of the extension 7 is formed parallel to the top side 17 of the base plate 4. The eyelet forms a round engagement area 18. The intended pulling direction 21, in which the holding element 1 is to be inserted into the receptacle 12 of the carrier 9, is indicated by an arrow.

[0025] A diameter 19 of the base plate 4 is larger than a maximum lateral extension of the eyelet 2 so that the base plate 4 limits a movement of the holding element 1 through an opening which corresponds to the maximum lateral extension of the eyelet 2.

[0026] Fig. 6 shows a side view of the holding element 1 inserted into the carrier 9 in a holding position rotated 90° around its longitudinal axis.

[0027] Fig. Figure 7 shows, by way of example, the use of four holding elements 1 for lifting a concrete formwork element 13. The holding elements 1 are inserted from below in the tensile direction 21 into receptacles 12 of the supports 9 and are held in the eyelets 2 by hooks 14. When the load is lifted by means of chains 15, a tensile force is exerted on the holding elements 1. The base plate 4 limits the upward movement of the holding element 1, resulting in a force transfer to the supports 9 and the load being lifted.

[0028] In a holding element 1 comprising an eyelet 2, an elongated, preferably cylindrical, base body 3 and a stop element 22, it is proposed that a lateral extension 5 of the stop element 22 is greater in at least two mutually transverse directions than a lateral extension 6 of the base body 3.
