Production of clamping points with free-floating closure.
Tensioning of the formwork according to a defined anchor grid. Production of sharp-edged, bleeding and discoloration-free anchor points by means of a support cone with a closed-cell 10 mm thick sealing foam ring on the formwork side and a rear sealing foam ring between the spreader and support cone. Support cone height = 50 mm. The formwork tie has to be re-tensioned during the concreting process.
Sealing of the clamping point with a free-floating concrete cone without contact to the lateral wall of the clamping point. For installation, the cone is glued in the expansion pipe and held in position in the anchor hole by placing a PE cord underneath. The sealing is carried out after sampling and after approval by the building owner.
The air-side clamping points are bonded with a one-component, grey adhesive. Gluing of the room-side clamping points (no damp rooms) with a single-component, non-flammable adhesive. Pre-cut fixed lengths are to be used as expansion tubes. Cutting of the expansion pipes by the customer must be avoided.
