Problems solved by technology

The process is complex and carries a high risk of error, since the infrastructure and especially the location situation are not suitable
This results in enormous bundling and assembly costs as well as delays in delivering the assembled rope

Embodiment Construction

[0018] figure 1 The pretensioning cord 1 is shown in a partial view, in which the connection of the longitudinal element 1 ′ to one of the connecting elements 2 of the pretensioning cord 1 is shown. The connecting element 2 is designed as a fork-shaped sleeve 4 as shown. It can also be designed as an eyelet sleeve according to the application.

[0019] According to the invention, the longitudinal element 1 ′ consists of a plurality of strands, each of which is arranged close to one another in parallel, of which the strands 3 a , 3 b , 3 c can be seen, which are anchored in the connecting element 2 .

[0020] The connecting element 2 has a funnel-shaped opening 5 for receiving the cables 3a, 3b, 3c and a transverse circular hole 6 for receiving anchor bolts or the like.

[0021] The ropes 3 a , 3 b , 3 c consist of a plurality of strands 7 , which in each strand are stranded with one another and pressed against one another at the end sides in the region of the funnel-shaped o...

Abstract

The invention relates to a prestressing cable (1), in particular for static structures, said cable being provided with a longitudinal element (1') and connection elements (2) at the end faces of said element. The longitudinal element (1') has a plurality of stranded wires, the end faces of which are anchored into the connection elements (2). The prestressing cable (1) is composed of multiple approximately parallel strands (3a, 3b, 3c), each of which comprises multiple stranded wires (7). The wires (7) are spread apart at their end faces in the funnel-shaped opening (5) of the respective connection element (2) and anchored by a casting process, wherein the frustum-shaped funnel widens away from the strands (3a, 3b, 3c). The straight arrangement of multiple strands results in particular in the significant improvement of the properties relating to vibrational loads even with wires of high strength.

Description

technical field [0001] The invention relates to a pretensioning rope (Vorspannlitze), especially for static construction, with a longitudinal element and an end-side connecting element, wherein the longitudinal element has a plurality of strands (Draeht), which at the end side are anchored in the connecting element. Background technique [0002] This type of pretensioning rope is mainly used in pretensioned concrete structures such as reinforced concrete bridges or flat roofs of office buildings, commercial buildings, teaching buildings and sports facilities, and is also used in rock anchoring or ground anchoring and similar structures . This type of pretensioning rope consists of a multi-wire strand structure (Seilkonstruktion), which is automatically inserted accordingly as individual strands (Strang) and is usually used in the end-side connecting element by means of a complex wedge system , such as using end pins as stop elements for anchoring. [0003] In the resultin...
