AI Technical Summary
Existing facade panel anchors suffer from rigid connections between the built-in and fastening parts, leading to unfavorable stress states due to bending moments, necessitating larger component dimensions and costly, complex installation processes.
The facade panel anchor is designed with a two-part built-in part featuring an articulated connection, allowing adjustment of the angle relative to the panel, and is installed with a protective body during concreting to avoid bending moments, with the connecting part mounted outside the concrete after hardening, using a fastener on a formwork element.
This design enables the transmission of primarily tensile forces while minimizing bending moments, reducing component size and simplifying the installation process by allowing partial embedding and avoiding complex joint formation within the concrete.

Abstract
Description
[0001] The invention relates to a facade panel anchor for the adjustable anchoring of concrete facade panels according to the preamble of claim 1.
[0002] A facade panel anchor of this type is known from DE 10 2011 102 379 A1. This facade panel anchor comprises an embedded component that is at least partially embedded in the concrete of the facade panel to be fastened. The facade panel anchor further comprises a fastening component that can be attached to a supporting structure, such as a concrete wall, a concrete beam, a steel beam, or masonry, to support the facade panel. The facade panel anchor also includes a connecting component that joins the embedded component and the fastening component and serves to transmit tensile forces.
[0003] A disadvantage of conventional facade panel anchors is that the mounting component and the fastening component are rigidly connected by the connecting piece. This rigid connection can lead to stress in the connecting piece under unfavorable load application conditions, requiring the connecting piece and adjacent components of the mounting component or fastening piece to withstand not only tensile forces but also bending moments. These bending moments are undesirable and necessitate correspondingly larger dimensions for the facade panel anchor components.
[0004] Based on this state of the art, the object of the invention is therefore to propose a facade panel anchor that avoids the aforementioned disadvantages with regard to the introduction of bending moments.
[0005] This problem is solved by a facade panel anchor according to the teaching of claim 1.
[0006] Advantageous embodiments of the invention are the subject of the dependent claims.
[0007] The facade panel anchor according to the invention is based on the fundamental idea that the installation part is designed in two parts, with a hinged connection provided between the two parts. The hinged connection on the installation part allows the angle of inclination of the connecting part relative to the facade panel to be adjusted. As a result of the adjustable angle of inclination due to the hinged connection in the installation part, it is possible to align the facade panel when it is attached to the supporting structure in such a way that essentially only tensile forces are transmitted to the facade panel anchor, while the introduction of bending moments is largely prevented.
[0008] In conventional facade panel anchors, the embedded component is initially cast completely into the concrete of the facade panel during its production. To allow for later sorting of the connecting element on the embedded component, the embedded component is encased in a protective cover, for example, made of expanded polystyrene, during the casting process. Once the concrete has hardened, the necessary connection elements of the embedded component can be exposed by removing the protective cover, and the connecting element can then be installed. This method of installing the facade panel anchor is extremely inconvenient and time-consuming when a hinged connection is present. Therefore, according to a preferred embodiment, a fastening element is provided on the embedded component, enabling it to be attached to a formwork element that can be cast into the concrete of the facade panel.
[0009] The fastening element is attached to the embedded component in such a way that the hinge connection and the second part of the embedded component, attached to the connecting piece, are located outside the concrete of the facade panel. As a result, the embedded component is only partially embedded in the concrete of the facade panel. By pre-assembling the embedded component with its fastening element to the formwork element suitable for embedding in concrete, the first part of the embedded component, necessary for attaching the connecting piece to the embedded component, is positioned outside the concrete of the facade panel. This eliminates the need to encase the embedded component during the embedding process in the facade panel.
[0010] The design of the hinge joint of the component is fundamentally arbitrary. According to a particularly simple embodiment, the hinge joint is formed by two coaxially mounted connecting discs. These connecting discs join the two parts of the component and, through their coaxial arrangement, create the necessary hinge joint.
[0011] The design of the fastening element on the embedded component is also fundamentally arbitrary. The fastening element can be designed particularly simply as a fastening plate. The fastening plate can connect two concrete lugs, which can be attached to reinforcement elements that are embedded in the concrete of the facade panel.
[0012] To attach the mounting plate to the formwork element, the mounting plate can have a pattern of holes to which, for example, screws or nails can be attached. To achieve an angled installation of the embedded part of the component on the formwork element, the mounting plate can, at least with the section containing the holes, project from the concrete lugs at an acute angle.
[0013] The connecting element can preferably be designed in the form of a threaded rod. For attaching the threaded rod to the mounting part or the fastening part, both the mounting part and the fastening part can each have a crosshead through which the ends of the threaded rod pass.
[0014] One embodiment of the facade panel anchor is shown schematically in the drawings and is explained below by way of example.
[0015] They show: Fig. 1. A facade panel anchor mounted in a facade panel, in side view; Fig. 2 the facade panel anchor according to Fig. 1 before mounting on the facade panel in side view; Fig. 3 the facade panel anchor according to Fig. 2 in a top view; Fig. 4 the facade panel anchor according to Fig. 2 in an exploded view.

The lower end of the two concrete tabs 09 Each element is also embedded in the concrete. 10 in connection. In this way, the weight of the facade panel can be reduced. 02 securely in the facade panel anchors 01 to be initiated. The two concrete tabs 09 are secured by a mounting plate 11 connected to each other. Before the concrete for the facade panel was poured. 02 will the mounting plate 11 on a formwork element 12 attached to ensure the exact installation position of the two concrete tabs 09 in the hardened concrete of the facade panel 02 to ensure.
[0020] By appropriately attaching the mounting plate 11 on the concrete tabs09 It is also ensured that a joint connection formed by two coaxial connecting screws 13 outside the hardened concrete of the facade panel 02 This joint connection is located. 13 connects the lower part of the built-in component 06 with an upper part of the built-in component 06 , which is from a transverse head 14 is formed by appropriately changing the angle of attack between the transverse head. 13 and the two concrete tabs 09 can the connecting part 08 so that after the facade panel is installed 02 on the supporting structure 03 essentially only tensile forces remain in the facade panel anchor 01 must be transferred.
