Abstract

The anchor (10) has separate prefabricated joint socket elements (16A, 16B) arranged in respective connecting zones that are located between a connecting element (14) and anchoring elements (12A, 12B). The prefabricated joint socket elements are rigidly connected with the connecting element or with the anchoring elements by preformed end portions of the joint socket elements. A set of connectors retains the preformed end portions in end regions of the assigned anchoring elements and/or connecting element.

Description

FIELD OF THE INVENTION

The invention relates to an anchor for connecting two relatively movable components according to the features of the preamble of claim 1 and a method and apparatus for its preparation according to the preamble of claim 8 and claim 11. Accordingly, two anchoring elements are provided at both ends of the assembly , which are each connected to the one or the other of the components to be interconnected, such as a masonry and a facing shell, connectable. Between the two anchoring elements, an elongate connecting element is provided. Of the anchoring elements is at least one articulated, in particular ball joint-like, with the respectively associated connection end of one or the other anchoring element connected by means of an articulated thickened part.

TECHNOLOGICAL BACKGROUND

Instead of inherently rigid connection anchors, non-rigid connection anchors have been used for decades, so that e.g. caused by different heat expansion relative displacements of the components to be connected are not inhibited by the connecting anchor.

From the CH-PS-441 679 a connection anchor for building parts is known in which the connecting element located between the two anchoring elements has a resilient portion. Typically, an attenuator is provided on the resilient portion to reduce undesirable degrees of vibration of the connection anchor to a tolerable level.

From the CH 565 908 A5 another anchor for connecting two relatively movable structural parts is known in which a connecting element located between anchoring elements is inherently rigid and connected in a ball-like manner to the connecting ends of the anchoring elements. For this purpose, the anchoring elements have hemispherical thickenings at their connecting ends, over which a connecting element designed as a tube is pushed and deformed into retaining collars by means of crimping around the hemispherical thickenings. In order to enable a coaxial alignment of the anchoring elements with the connecting element in the unloaded state of the armature, spring-like support means can be clamped within the housing-like connecting element between the hemispherical thickenings of the anchoring elements. These can exert aligning forces on the hemispherical thickenings and allow, in moderation, a change in spacing between the hemispherical thickenings within the box-like connecting element.

From the CH 576 562 A1 is another connecting anchor for relative to each other movable structural parts known in which the connecting element is rigid and thus does not allow resilient distance changes between the spherical thickenings of the anchoring elements. The in this way rigid and generally uniform thickness connecting element is in one piece, for example made of a steel rod. In the ends of ball cup-shaped recesses for receiving the spherical thickened connecting ends of the anchoring elements are incorporated. The depth of these receptacles is dimensioned so that after insertion of the spherical thickenings of the connecting elements, the free ends of serving as a compensation part connecting element can be flanged by a deformation step to the spherical thickenings. In this case, the crimping edges leave sufficient scope for pivoting the anchoring elements with respect to the connecting element up to a maximum angular deflection.

Finally, out of the EP 0 995 850 A1 another anchor known for connecting two relatively movable building parts, in which as a one-piece connecting element, similar to the CH 565 908 A5 , A tubular connecting element is provided, but can be dispensed with the support elements inside the tube. In order to ensure the desired compressive stiffness of the connecting element, the tube is tapered at the end of the connecting zone like a sickle in its cross section, so that the spherical-like thickening at the connecting end of the respective anchoring element is axially immovable or almost immovable. Also in this connection anchor is, similar to the CH 576 562 A1 chosen for the connecting element an outer diameter which is chosen to be significantly larger than the outer diameter of the spherical thickenings at the connecting ends of the anchoring elements. In this way, the ball joint sockets at the two ends of the connecting element can have sufficient material thickness to ensure the required strength of the ball joint connections, without the costly machining operations are required on the connecting element. Rather, the flanges can take place at the connecting ends of the connecting elements for the partial encompassing of the spherical thickenings of the anchoring elements by so-called roll deformation.

Furthermore, from practice, from which the invention proceeds, a still further anchor for connecting two relatively movable structural parts is known in which at least one of the articulated connections between the two anchoring elements and the connecting element consists of a straight pipe section, which is crimped at both ends is at its first end a thickening articulated and at its opposite second end another thickening rigidly to embrace. The one thickening is on the anchoring element and the other thickening is provided on the connecting element.

PRESENTATION OF THE INVENTION

The invention is based on the recognition that the conventional hinged connections suffer from the difficulty of achieving the desired dimensional stability of the connecting anchors and that it is difficult in the material deformation to produce a hinged connection that the joint is neither too tight nor too loose becomes. Based on this, the invention is based on the problem of simplifying a precise articulated connection between the connecting element and at least one of the anchor elements in a generic connection anchor for two spaced-apart components. To solve this problem, a connecting anchor with the features of claim 1 and a method with the features of claim 8 and a manufacturing apparatus with the features of claim 11 is proposed. Accordingly, it is provided in a generic connection anchor, that in at least one of the connection zones located between the connecting element and the anchoring elements, a separate prefabricated socket element is arranged or can be arranged. The prefabricated socket element has a first end portion preformed to a socket and a second end portion preformed to a fastener. The thickening on the anchoring element or on the connecting element provided in at least one of the respective connecting zones is partially encompassed or encompassable by the first preformed end region of the associated separate prefabricated joint cup element. For this purpose, a final deformation of the separate prefabricated joint socket element takes place, so that an axial fixation of the thickening takes place. The at least one separately prefabricated joint socket element is rigidly connected or rigidly connectable by means of its second preformed end region to the connecting element or to at least one of the anchoring elements. The joint-like connection according to the invention may be, for example, ball joint or part ball joint-like, universal joint-like or any other known in the art articulation in which a thickening is claw-like, ring-like or in a similar manner teilumfasst.

As a rule, two joints are provided and both are of identical construction. However, the second articulated connection can also be embodied in any other manner that can be found in the prior art, without departing from the inventive solution.

Accordingly, the invention is based on the idea of providing at least one separately prefabricated socket element for the connection anchors. As a result, the mechanical requirements for the joint connection can be optimally taken into account, both with regard to the use of materials, as well as the selection of materials and material processing. It is also possible to use the joint socket elements according to the invention in a uniform size with connecting and anchoring elements of different dimensions and in particular different cross-section, because their load capacity is particularly high. The provision of many different sizes is therefore avoidable. The socket elements can be particularly precise and before especially made to measure. The same applies to the total length of the connecting element and the socket element (s). It is also within the meaning of the invention, when the connecting element and the socket elements are made in one piece.

It is now possible in various ways to carry out the invention: In principle, the separate joint socket elements can be made of e.g. solid metal material, e.g. be made by turning. Preference is given to forgings, i. generally prepared by forming separate prefabricated socket elements, in particular ball joint socket elements; this may also be about a tubular blank deformed joint socket elements. Wholly or partially prefabricated by forging separate joint socket elements achieve comparatively low material usage and high precision particularly high strengths. This also applies if the connecting element and the joint socket elements form a one-piece forging or are joined together.

The rigid connection of the separate prefabricated socket elements with the anchoring elements or the connecting element can be achieved in various ways, e.g. also done by welding. Particularly preferred is a compound in which the rod-shaped connection-side end of the anchoring element or the connecting element is provided with at least one closed or spirally encircling or interrupted Umfangsrillung. Such deformations can be made by roll forming or machining and e.g. in the form of a single or multiple circumferential self-contained grooves or a spirally-shaped groove, e.g. a screw thread can be realized.

The crimping of the separate prefabricated socket element required after joining the anchoring element and the connecting element to the articulated connection point can in principle be based on conventional methods Done way. Particularly advantageous is a, in particular radial projection of the separate prefabricated joint socket element has proven at or near its mouth or bead. This can u. A. Improve the subsequent strength and / or precision of the joint connection and / or allow reshaping by crimping with relatively simple tools. Such a discharge is independent of individual features of claim 1 of independent inventive importance.

The cross-sectional ratio or the outer diameter of the separate joint cup element, to the cross-sectional areas or diameters of the adjacent anchoring and / or connecting elements can be chosen freely. Outer diameters that are 1.0 to 4.0 times the cross-sectional dimension of the anchoring element and / or connecting element have proven particularly advantageous. Particularly preferred is a diameter ratio of 1.5 to 3.0. In extreme applications, however, diameter ratios below 1.0 are executable.

The above-mentioned and the claimed components to be used according to the invention described in the exemplary embodiments are not subject to special conditions of size, shape, material selection and technical design, so that the selection criteria known in the field of application can be used without restriction.

Further details, features and advantages of the subject matter of the invention will become apparent from the subclaims, as well as from the following description and the accompanying drawings, in which - by way of example - an embodiment of an anchor is shown. Also, individual features of the claims or of the embodiments may be combined with other features of other claims and embodiments.

B. a rolling operation to the thickening 18A, 18B are partially flanged, so that a sufficient pivoting mobility of the adjacent elements remains despite axial immobility.

Figure 2C shows an application situation of the connecting anchor, in which the building parts have shifted against each other.

A rigid connection of the separate joint socket elements 16A, 16B with the connecting element 14 can also be effected, for example, by welding. Particularly preferred is one in the FIGS. 1 to 3 illustrated connection, wherein the rod-shaped connection-side ends of the anchoring elements 12A, 12B are provided with at least one closed or spirally encircling or interrupted Umfangsrillung, such as with a screw thread, the second end portions 17B of the separate joint socket elements 16A, 16B then a corresponding mating thread or receptacle , in the example shown an internal thread having.

The after the joining of the anchoring elements 12A, 12B with the connecting element at the spherical connection point in the shape of the spherical Thickening 18A, 18B required crimping of the separate separate joint socket elements 16A, 16B can in principle be done in a conventional manner. An outer collar 19 of the separate joint socket elements 16A, 16B at its mouth end or flanged edge has proved to be particularly advantageous. This can u. A. Improve the subsequent strength and / or precision of the joint and / or allow reshaping by crimping with relatively simple tools.

As already mentioned, the separate joint socket elements 16A, 16B are preferably produced as forgings; this may also be about a tubular blank deformed joint cup elements 16C, as in FIG. 3 shown, in this embodiment, the one, formed from a pipe end portion second end portion 17B was formed into a pin 16C 'with external thread, which is screwed into an internal thread of the connecting element or one of the anchor elements. By forging the separate joint socket elements, high strengths are achieved with comparatively little use of material.

The aspect ratio or the outer diameter D1 of the separate joint cup elements to the cross-sectional areas or diameters D2 and / or D3 of the adjacent anchoring and / or connecting elements can be chosen freely. Outer diameters that are 1.0 to 4.0 times the cross-sectional dimension of the anchoring element and / or connecting element have proven particularly advantageous. Particularly preferred is a diameter ratio of 1.5 to 3.0. In extreme applications, however, diameter ratios below 1.0 are executable.
