Abstract
A device is provided for joining pre-cast concrete sections, the device including a cable loop, wherein the cable sections forming bent portions of the cable loop have sleeves for keeping the cable sections in a bent-over position. The sleeves are plastically deformable before bending and surround the bent portions of the cable sections, but the material of the sleeves is such that the sleeves break under return deformation.
Claims9
A device for joining pre-cast concrete sections, the device comprising:
- a cable loop having cable sections forming bent portions of the cable loop;
- and
- a sleeve surrounding at least one of the bent portions of the cable loop and maintaining the at least one bent portion in a bent-over position at an angle of approximately 90° at least for a period after pre-casting in a precast concrete section and during transportation and storage of the concrete section by the sleeve,
- wherein the sleeve comprises a material which is plastically deformable before bending the cable sections and sleeve, but which breaks under return deformation of the cable sections and sleeve, and
- wherein the sleeve comprises a strap having at each end two protruding wings for engaging around portions of cable sections of the cable loop.

A device for joining pre-cast concrete sections, the device comprising:
- a cable loop having cable sections forming bent portions of the cable loop;
- an insert body insertable into a recess of a pre-cast concrete section, the insert body having a U-shaped profile and at least one opening for the cable loop, a portion of the cable loop which extends from the pre-cast concrete section lying in a channel of the U-shaped profile of the insert body in a bent-over position;
- and
- a retainer configured to keep the portion of the cable loop in the bent-over position, the retainer being formed as a tubular sleeve completely surrounding at least one of the bent portions of the cable loop, the sleeve retaining the at least one bent portion in the bent-over position at an angle of approximately 90° at least for a period after pre-casting in the pre-cast concrete section and during transportation and storage of the pre-cast concrete section,
- wherein the sleeve comprises a plastic material which is plastically deformable before bending the cable sections and sleeve, but which breaks under return deformation of the cable sections and sleeve.
