Description

The present invention relates to a retaining clip for building materials, in particular for fixing wall covering elements to masonry and/or for holding drywall elements, the retaining clip having at least one elastic region and two clamping legs spaced apart therefrom. Furthermore, the present invention relates to a wall covering and a method for fixing wall covering elements to masonry and/or drywall elements, using a retaining clip for building materials, with an elastic region and two clamping legs spaced apart therefrom.

During the construction phase of buildings, it is important that masonry is protected from penetrating water and moisture, for example due to rain, snow or dew. For this purpose, various types of covers are known in the state of the art, which are placed on the masonry and fixed in place. These are usually flexible tarpaulins which are fixed in place with the help of weights or, advantageously, with retaining clips. However, known retaining clips can only be used comfortably for a wall thickness of essentially the same. A building during the construction phase, however, can have many different wall thicknesses. While the inner walls of a building are normally 11.5 cm thick, the outer walls of a building can measure a wall thickness of up to 52 cm. In practice, several retaining clips of different sizes are therefore necessary to adequately protect a building during the construction phase.

From the DE 20 2011 002 768 U1 Such a retaining clip for masonry covers is known, which can be attached to a waterproof, fully flexible cover on a masonry. The retaining clip is a flexible clip that is open on one side with which the cover can be attached and secured over the masonry. The retaining clip has a bulge or extension outwards away from the clamping area of the clip in order to be able to attach the cover to masonry of different thicknesses. This means that although it is theoretically possible to attach a cover to masonry walls of different thicknesses, in practice it can only be used to a limited extent and only if there are small differences. With large differences in wall thicknesses, large angular offsets between the two clamping legs arise due to the concept. In the case of very thick and/or thin walls, this can lead to a limited clamping effect because the entire clamping leg is not in contact with the wall. In particular, with very thick walls, the retaining clip can slide upwards, since the clamping force due to the deformation of the retaining clip acts primarily in the upper area of the clamping legs, resulting in an upward force.

From the BE 544 694 A A system for clamping brush handles is known, which is formed in the form of a spring loop, both ends of which are extended and provided with hooks.

From the US 3,102,614 A a wire clip for attaching an elongated runner to an elongated ceiling element is known.

From the FR 2 159 775 A5 a clamp made of elastic metal wire is known, this clamp comprising a loop which defines a first support surface and a web which is formed from two legs which form a second support surface.

From the US 3 858 364 A a demountable temporary structure for use in protecting a building unit against the effects of the weather is known, the temporary structure comprising at least a first and a second wall arranged on different sides of the unit and a roof extending from one wall to the other to cover the space therebetween.

The object of the present invention is therefore to provide a retaining clip for building materials, a wall covering and a method for fixing wall covering elements, which provide a consistently high clamping effect with very different wall thicknesses.

The problem is solved by a retaining clip, a wall covering and a method for fixing wall covering elements with the features of the independent patent claims.

A retaining clip for building materials is proposed for fixing wall covering elements to masonry and/or for holding drywall elements. The retaining clip has at least one elastic region and two clamping legs spaced apart from it. The clamping legs are designed to fix wall covering elements on masonry and/or for holding drywall elements on masonry and/or on support elements. The elastic region has at least one torsion spring with a torsion axis. Here, the torsion axis describes the axis around which the torsion spring essentially stretches. A torsion spring, which can also be called a torsion spring, is understood to mean in particular a spring that generates a torque about the torsion axis. If the torsion spring is advantageously a helical spring with at least half a turn, the torsion axis runs essentially centrally to it half a turn. The clamping legs extend essentially in the direction of the torsion axis of the torsion spring. When tensioning the retaining clip, the clamping legs are deflected essentially without any angular offset to the torsion axis and/or to each other. In contrast to the current state of the art, this means that very different wall thicknesses can be clamped with a consistently high clamping force. A construction company therefore only needs a single retaining bracket for all construction projects. This has the advantage that there is no need for complex storage of different retaining clamps and no additional planning is necessary for each construction site. Within the construction company, a single clamp can cover all needs. This applies to every building project, all thicknesses/thicknesses of walls and all variants of building materials. Likewise, the risk of the retaining clip sliding upwards is low in very thick masonry, since the non-existent and/or very small angular offset of the clamping legs to one another results in a uniform clamping effect and therefore no upward force acts. In addition, the proposed design of the retaining clip with torsion spring can simplify transport and/or interim storage before installation. For storage purposes, the torsion spring can be pushed over a rod-shaped element, for example over a strut of a scaffolding, a ladder and/or over a rolled-up tarpaulin. In addition to the use cases already mentioned above, the clamp can be used for many other purposes. An additional application arises, for example, when covering formwork, especially concrete formwork, in order to ensure uniform drying in heavy rain and/or strong heat.

It is particularly advantageous if the clamping legs extend essentially parallel to the torsion axis of the torsion spring, for parallel deflection of the clamping legs when tensioning the retaining clip. Due to the parallel Deflection of the clamping legs when tightening the retaining clamp means that the clamping legs essentially rest against the masonry over their entire length, which allows an even more constant clamping force to be achieved, especially when clamping very different wall thicknesses.

It is advantageous if the elastic region has at least two connecting legs, each of which connects one of the two clamping legs to one end of the torsion spring. When the retaining clip is tightened, the two clamping legs are deflected in opposite directions from one another. The connecting legs thus form a translation from the ends of the torsion spring to the clamping legs. This makes it possible to clamp walls of different thicknesses depending on the length of the connecting legs. Due to the lever arm law, the length of the legs also has a direct effect on the clamping force that acts on the masonry. In order to ensure that the connecting legs rest on the top of the masonry, at least one of the two connecting legs can have at least one bend. This makes it possible to compensate for the offset of the connecting legs due to the height of the torsion spring.

It is also extremely advantageous if the connecting legs extend tangentially or radially to the torsion spring and/or transversely to the clamping legs. While the production costs are lower with a tangential extension of the connecting legs to the torsion spring due to fewer bending points, a radial extension results in slightly less space being required. If the connecting legs are also arranged transversely to the clamping legs, additional installation space can be saved when the retaining clip is attached, particularly on the masonry, and the torsion spring lies flat on the masonry.

There are also advantages if the connecting legs and/or the ends of the torsion spring have an interlock. This entanglement contributes to a balanced balance of forces in the elastic range when tensioning the retaining clip.

It is particularly advantageous if the two connecting legs extend essentially parallel to one another in a relaxed initial state or lead to one another in the direction of the clamping legs. A parallel extension of the connecting legs, in particular with an interlocking of the ends of the torsion spring, is advantageous. If, on the other hand, the connecting legs have an interlock, the connecting legs preferably lead towards one another in the direction of the clamping legs. This leads to a very compact design of the retaining clip.

It is also extremely advantageous if at least one of the two clamping legs and/or one of the two connecting legs has at least one grip area for gripping at least one leg. These grip areas allow the retaining clip to be clamped very easily, thus ensuring easy installation. The at least one grip area can be placed on the clamping leg and/or the connecting leg. Likewise, the clamping leg and/or the connecting leg can be at least partially curved and thus form the grip area.

It is advantageous if an end cap, in particular made of plastic and/or rubber, is attached to at least one free end of the clamping legs and/or at least one of the free ends of the clamping legs is bent to protect the building materials to be fastened. This prevents damage to wall covering elements and/or drywall elements. It is also conceivable that an additional support element is fixed to the free ends of the clamping legs or to be attached to the clamping leg To be able to adapt the surface, it is arranged movably. The support element extends in particular transversely to the clamping legs in order to enlarge the area of support on wall covering elements and/or drywall elements.

There are also advantages if the retaining clip has a coating, in particular made of plastic, rubber, paint and/or powder coating. This can prevent damage to wall covering elements and/or drywall elements.

It is particularly advantageous if the retaining clip, the grip areas, the coating and/or the end caps have a coding, in particular a color coding, to identify a specific dimension and/or a specific area of use. In addition to the size or length of the torsion spring, the connecting legs and/or the clamping legs, the material, the material thickness, the clamping force and/or the shape of the retaining clip, among other things, can also be marked in order to prevent confusion. The construction company can also be identified using its own company color, for example.

It is also extremely advantageous if the two clamping legs each have at least one clamping area, the clamping areas extending in the direction of the torsion axis essentially in connection with the torsion spring. The wall covering element can be fixed to the wall and/or the drywall elements can be held using these clamping areas.

Advantages also arise if the clamping legs and/or the connecting legs have different lengths and/or at least one of the two clamping legs and/or the two A length-changing element, for example a telescopic sleeve, is attached to the connecting leg. This means that the different lengths ensure easy engagement between the two clamping areas and/or the two connecting legs, thus simplifying assembly. In addition, the length of the connecting legs can be used to control the position of the torsion spring in relation to the masonry. On the other hand, the lengths of the clamping legs and/or the connecting legs can be changed using the length-changing element. This ensures good clamping even with very thick walls and, at the same time, a compact design for this retaining clip. In addition, the difference in length between the two clamping legs and/or the two connecting legs can be changed using such a length-changing element. It is also conceivable that at least one of the clamping legs and/or one of the connecting legs takes on the function of the length-changing element.

There are particular advantages when the retaining clip is made in one piece. The retaining clip can thus be manufactured very cost-effectively.

Furthermore, a wall covering is proposed with a wall covering element, in particular made of a flexible material that covers a masonry in an overlapping manner at the top, and a retaining clip for fixing the wall covering element to the masonry. The retaining clip is designed according to the previous description.

Furthermore, a method for fixing wall covering elements to masonry and/or for holding drywall elements using a retaining clip for building materials is proposed. The retaining clip has an elastic area and two clamping legs spaced apart from it, according to the previous description. When tensioning the retaining clip the elastic region, which has at least one torsion spring, is elastically deformed and the two clamping legs are deflected essentially without angular offset to a torsion axis of the torsion spring.

It is particularly advantageous if the two clamping legs are deflected essentially parallel to the torsion axis of the torsion spring.

Figure 1 shows a perspective view of a retaining clip 1 in a schematic representation. The retaining clip 1 has a torsion spring 2, which in the present application example is designed as a coil spring with several turns. A torsion axis TA of the torsion spring 2nd extends centrally to the windings Figure 1 the torsion axis TA runs from top to bottom. The torsion axis TA describes the axis around which the torsion spring 2 essentially stretches. Although coil springs are usually known as torsion springs 2 in the prior art, the torsion spring 2 can also be another element which essentially achieves an elastic torsional effect about the torsion axis TA. For example, a torsion bar would also be conceivable as a torsion spring 2.

Two connecting legs 3 extend radially adjacent to the torsion spring 2, with the connecting legs 3 extending essentially parallel to one another. The connecting legs 3 connect the torsion spring 2 with two clamping legs 4, the connecting legs 3 extending transversely to the clamping legs 4. In order to obtain a parallel deflection of the clamping legs 4 and thus a constantly high clamping effect even with very different wall thicknesses, the two clamping legs 4 extend essentially parallel to the torsion axis TA.

Figure 2a shows a top view and the Figure 2b a front view of a retaining clip 1 in a relaxed initial state according to an embodiment. Just as in the application example of the Figure 1 the torsion spring 2 is a helical spring. The torsion axis TA thus extends essentially centrally to the coils of the torsion spring 2.

The connecting legs 3 connect the two clamping legs 4 to one end of the torsion spring 2, whereby the ends of the torsion spring 2 have an interlock 5. In the relaxed state, the connecting legs 3 extend essentially parallel to one another. If the retaining clip 1 is tensioned on the two connecting legs 3 and/or the two clamping legs 4 in an opposite tensioning direction SR during tensioning, the torsion spring 2 is twisted. The interlock 5 reverses the twisting direction of the torsion spring 2, thus achieving a balanced force ratio.

Figure 3a shows a top view and the Figure 3b a front view of a retaining clip 1 in a tensioned, attached state according to an exemplary embodiment similar to that shown in the relaxed state Retaining clip 1 in the Figures 2a and 2b . In the present exemplary embodiment, the retaining clip 1 is tensioned and placed on masonry 6 in order to fix a wall covering element 7.

By tensioning the torsion spring 2 of the retaining clip 1 from the relaxed state, as shown in the Figures 2a and 2b shown, in the tensioned state, as in the Figures 3a and 3b As shown, a torque results. This torque is transmitted via the connecting legs 3 to the clamping legs 4 and, based on the lever arm law, is translated into a clamping force which acts in a clamping direction KR. The clamping direction KR is opposite to the clamping direction SR in the Figures 2a and 2b .

The clamping force is mainly determined by the spring properties of the torsion spring 2. The spring properties are influenced, among other things, by the number and diameter of the coils as well as the wire thickness and the material of the spring. In addition to the spring properties of the torsion spring 2, the lengths and angles of the connecting legs 3 also have a direct influence on the clamping force that fixes the wall covering element 7 on the masonry 6.

In addition to the spring properties, the diameter of the windings and the lengths of the connecting legs 3 in particular have an influence on the area of application. When using the retaining clip 1 on very thick masonry 6, the diameter of the turns and/or the length of the connecting legs 3 should be chosen to be rather large. In order to change the spring properties independently, the wire thickness and material can be changed, among other things.

Since the retaining clip 1 is advantageously made of a hard material, in particular spring steel, and the wall covering element 7 should not be damaged when the retaining clip 1 is placed on the masonry 6, the free ends 8 of the clamping legs 4 are bent. An end cap made of a softer material, in particular plastic or rubber, would also be conceivable.

The two clamping legs 4 each have a clamping area 9 for transmitting the clamping force, which defines the area that rests on the wall covering element 7. In the present embodiment, the respective clamping area 9 thus extends essentially from the connection of the torsion spring 2 in the direction of the torsion axis TA to the beginning of the bent free ends 8 of the clamping legs 4.

Due to the symmetrical design of the retaining clip 1, the clamping forces on the masonry 6 are also fundamentally symmetrical. As a result, the retaining clip 1 is essentially positioned centrally on the masonry 6 after being attached. The torsion axis TA is therefore located on a central plane ME of the masonry 6.

In Figure 4 is a plan view of a retaining clip 1 in a tensioned state, attached to a masonry 6, according to a further embodiment. In contrast to the Figure 3a In the embodiment shown, drywall elements 10, in particular plasterboard or comparable panels, are fixed to the masonry 6. Since in the drywall construction sector the drywall elements 10 are often also fixed alone or in addition to the masonry 6 to substructures and/or studwork made of profiles or beams, the present retaining clip 1 with suitable dimensions is also conceivable for such structures.

In addition, the Figure 4 different length connecting legs 3. This results in a shift of the torsion axis TA and thus of the retaining clip 1 to the center plane ME of the masonry 6. As in Figure 4 As shown, this can result in the holding clamp 1 being moved to the side of the shorter connecting leg 3. This can be advantageous, particularly in limited space. In addition, the clamping forces of the two clamping legs 4 on the drywall elements 10 can differ due to the different lengths of the two connecting legs 3.

In Figure 5 is a front view of a retaining clip 1 shown in a relaxed initial state according to an alternative embodiment. In contrast to the exemplary embodiment Figure 2b Here the clamping areas 9 have a different length. This can be used in particular to facilitate engagement between the clamping legs 4 and/or clamping areas 9 and thus to tension the retaining clip 1. In addition, the retaining clip 1 has a grip area 11 on each of the clamping legs 4. This also serves primarily to tighten the retaining clip 1 more easily. The grip area 11 shown here is placed on the clamping legs 4. It is also conceivable that at least one of the clamping legs 4 is at least partially curved and thus forms the grip area 11.

Figure 6 shows a top view of a retaining clip 1 in a relaxed initial state according to an alternative exemplary embodiment. In contrast to the previous exemplary embodiments, the connecting legs 3 extend tangentially to the torsion spring 2. As a result, the connecting legs 3 form the interlock 5 for a balanced balance of forces. The clamping direction SR indicates that in this application example the clamping legs 4 are clamped in the clamping direction SR. When the retaining clip 1 is tightened, the entanglement 5 shifts in the direction of the torsion spring 2.

The Figures 7a and 7b each show a perspective view of a retaining clip 1 in a schematic representation according to different exemplary embodiments. In contrast to the previously described exemplary embodiments, here the clamping legs 4 do not extend essentially parallel, but only in the direction of the torsion axis TA of the torsion spring 2.

This shows Figure 7a a retaining clip 1 with clamping legs 4, whereby the clamping legs 4 are bent. In the present application example, additional support elements 13 are fixedly arranged on the free ends 8 of the clamping legs 4, which extend transversely to the clamping legs 4. These support elements 13 can also be arranged movably on the clamping legs 4 in order to compensate for a slight angular offset. If the support elements 13 are arranged movably on the clamping legs 4, a locking mechanism can also be provided. If such a retaining clip 1 is placed on a masonry 6 (cf. Fig. 3b ), only the free ends 8 of the clamping legs 4 and the additional support elements 13 shown here are in contact with the masonry 6. The support elements 13 increase the area of support to the masonry and thus improve the clamping effect.

The embodiment of the Figure 7b shows clamping leg 4 in a multi-bent shape or in a wave shape. If you put such a retaining clip 1 onto masonry 6 (cf. Fig. 3b ), the clamping legs 4 rest on the masonry 6 at certain points. It is also conceivable that the waveform is rotated by 90° about the longitudinal axis of the clamping legs 4. So The clamping leg 4 would rest against the masonry 6 over its entire height, with the contact surface being enlarged by the wave shape in contrast to the parallel extension of the clamping legs. In addition, the shows Figure 7b Length changing elements 12 for adjusting the lengths of the connecting legs 3. As shown schematically, these can be simple sleeves, to which one of the clamping legs 4 is attached and which can be moved linearly along the connecting legs 3. It is also conceivable that the connecting legs 3 are designed as a telescopic rod and thus also take on the function of the length changing elements 12. An adjustable length of the connecting legs 3 ensures a good clamping effect even with very thick masonry 6 and at the same time a compact design of the retaining clip 1. Such a length changing element 12 would also be conceivable for the clamping legs 4.

In Figure 8 is a front view of a retaining clip 1 in a tensioned state, attached to a masonry 6, according to an alternative embodiment. The two clamping legs 4 are at least partially curved, whereby they form the grip area 11. It is also conceivable that one of the two clamping legs 4 and/or at least one of the two connecting legs 3 forms the grip area 11.

Each of the clamping legs 4 has two clamping areas 9, which are separated by the respective grip area 11. It is also conceivable that each of the clamping legs 4 is constructed in such a way that only one of the clamping areas 9 is formed and/or rests on the masonry 6.

The retaining clip 1 has a coating 14, for example made of plastic, rubber, lacquer and/or powder coating. This coating 14 is shown in the Embodiment formed on the clamping legs 4 and on the connecting legs 3. It is also conceivable that at least one of the clamping legs 4, at least one of the connecting legs 3 and/or the torsion spring 2 has the coating 14. The coating 14 can be used to protect the masonry 6 and/or to identify a specific dimension, a specific area of application and/or a company affiliation of the retaining clip 1.

The present invention is not limited to the illustrated and described embodiment. Modifications within the scope of the patent claims are possible, as is a combination of the features, even if they are shown and described in different exemplary embodiments.
