WAYS OF IMPLEMENTING THE INVENTION

[0054] FIG. 1 shows a tension rod 10 comprising a full cross section 10 with a rolled thread. The tension rod 10 is a first example of a tension element of a system consisting of statically loadable components in a structure and has an end region 11 in which an outer thread 12 is formed. In the embodiment shown in FIG. 1, the outer thread 12 is configured as a rolled thread and extends over the end region 11 of a defined length on the one side of the tension rod 10. The second side of the tension rod 10 is not shown in FIG. 1 and can also be provided with an outer thread in its end region. However, it is also possible that the tension rod 10 is formed without such an outer thread 12 on its side not shown.

[0055] FIG. 2 shows a cable tension member 14 with a thread fitting 18 and thus a second example of a tension member of a system consisting of statically loadable components in a structure. The cable tension member 14 has an end region 15 at which the thread fitting 18 is arranged. The thread fitting 18 is pressed onto a cable 14 by means of a press socket 16 and has, in addition to the press socket 16, an outer thread region with an outer thread 16. The outer thread 16 of the cable tension member 14 from FIG. 2 corresponds to the outer thread 12 of the tension rod 10 from FIG. 1.

[0056] FIGS. 3a and 3b show a fork head 20 as an example of a connection component of a system consisting of statically loadable components in a structure, with the fork head 20 having an inner thread 22 and an eye 23. The inner thread 22 of the fork head 20 is configured such that it can interact with the outer threads 12, 16 of the tension rod 10 and the cable tension member 14. FIG. 3a shows a side view of the fork head 20, whereas FIG. 3b shows a top view of the fork head 20.

[0057] FIGS. 3c and 3d show a rod end 20 as a further example of a connection component of a system consisting of statically loadable components in a structure, with the rod end 20 having an inner thread 22 and an eye 23, which can be formed as in the fork head 20 from FIGS. 3a and 3b. FIG. 3c shows a side view of the rod end 20, whereas FIG. 3d shows a top view of the rod end 20. In contrast to the fork head 20, the rod end 20 has only one lug 21, not two lugs 21, as is apparent when comparing the two top views 3b and 3d.

[0058] FIG. 4 now shows an example of a two-part fork fitting, in which the fork head 20 with an inner thread 22 from FIGS. 3a and 3b was screwed onto the cable tension member 14 with a thread fitting 18 from FIG. 2. The inner thread 22 interacts with the outer thread 16. The fork head 20 could just as well be connected with the tension rod 10 from FIG. 1 in order to form a two-part fork fitting consisting of the fork head 20 with an inner thread 22 and the tension rod 10 with an outer thread 12. Of course, a rod end and a cable tension member or a tension rod can also be used analogously in order to form a two-part rod end fitting.

[0059] In the embodiment shown, the fork head 20 can be connected with either the cable tension member 14 or the tension rod 10 so that it is possible, even at the last second before the installation or even after the installation, to replace the cable tension member 14 with a corresponding tension rod 10 or vice versa without carrying out a new statistical calculation or having to adapt other components of the overall structure.

[0060] While in FIGS. 3a to 3d and 4 connector heads are shown as examples of a connection component, FIG. 5 shows a sleeve 30 as a further example of a connection component.

[0061] FIGS. 6a and 6b show a further embodiment of a fork head 20 with an inner thread 22. While FIG. 6a shows a side view of the fork head 20, FIG. 6b shows a front view of the fork head 20. The fork head 20 corresponds essentially to the fork head 20 shown in FIGS. 3a and 3b. Like the fork head 20 from FIGS. 3a and 3b, the fork head 20 shown in FIGS. 6a and 6b has two lugs 21 with a length in a tension direction, a width transverse to the tension direction and a thickness perpendicular to the length and width, through each of which a respective eye 23 is formed along the direction of the thickness through the lugs 21.

[0062] In contrast to the embodiment from FIGS. 3a and 3b, in the embodiment from FIGS. 6a and 6b an amount of the thickness of the lug 21 in a center, based on the direction of the width, is maximal and decreases towards two side regions 24 lying outside and opposite each other in the direction of the width. Thus, a high ridge 26 is formed in the center.

[0063] FIGS. 6c and 6d show a further embodiment of a rod end 20 with an inner thread 22. While FIG. 6c shows a side view of the rod end 20, FIG. 6d shows a front view of the rod end 20. The difference between the embodiment according to FIGS. 6c and 6d as compared to FIGS. 3c and 3d in turn lies in that an amount of the thickness of the lug 21 in a center, based on the direction of the width, is maximal and decreases towards two side regions 24 lying outside and opposite each other in the direction of the width. Thus, a high ridge 26 is formed in the center.

[0064] Thus, the system according to the invention, in particular according to the preferred embodiments from FIGS. 1 to 6d, makes it possible to randomly use different combinations of different tension elements and connection components while the loads of the overall system remain the same.
