Method and apparatus for the installation of a lifting loop, and part forming a lifting loop |
摘要 |
A method for the installation of a lifting loop in a fresh hollow core slab, said hollow core slab having its top surface broken for an opening substantially in line with a neck between the cavities, and said method comprises placing in the obtained opening a lifting loop-forming part set to bear against the hollow core slab's pre-stressing strands, the lifting loop-forming part's end sections being placed under the hollow core slab's pre-stressing strands by providing either a permanent or temporary deformation in the lifting loop-forming part. The invention relates also to an apparatus for implementing such a method, as well as to a lifting loop-forming part compatible with the method. |

1. A method for the installation of a lifting loop in a fresh hollow core slab, wherein said hollow core slab having a top surface broken for an opening substantially in line with a neck between cavities therein, said method comprising placing in the obtained opening a lifting loop-forming part set to bear against pre-stressing strands of the hollow core slab, wherein the lifting loop-forming partcomprises end sections that are placed under the pre-stressing strands by providing either a permanent or temporary deformation in the lifting loop-forming part during the placing of the lifting loop-forming part. |
