Hook strap

Hook strap comprising a transverse arm for abutment on a formwork girder having hook-shaped retainers disposed on opposite ends of the transverse arm for engagement below parts of a waler and tension elements for fixing the hook strap, wherein the transverse arm is formed as a non-rigid fiat ribbon of small thickness and wherein the surface produced by the fiat ribbon and the formwork girder is largely uniform and free of projecting steps or edges.

Hook strap comprising a transverse arm for abutment on a formwork girder having hook-shaped retainers disposed on opposite ends of the transverse arm for engagement below parts of a waler and tension elements for fixing the hook strap, wherein the transverse arm is formed as a non-rigid fiat ribbon of small thickness which can be adapted to formwork girders of different widths by conforming to the girder width without preforming the flat ribbon, and wherein the surface produced by the fiat ribbon and the formwork girder is largely uniform and free of projecting steps or edges, and wherein the ribbon forms a U-shaped recess during overlapping of the formwork girder, wherein the size of the U-shaped recess is adapted to the width of a flange of the formwork girder and the ends of the ribbon are provided with edge sections which are connected with tension elements.
