Multi-layered wall structure in panel format

摘要

The wall has a precast concrete inner layer unit, a lightweight concrete centre layer and a precast heat insulating outer layer. The inner layer consists of a lightweight concrete wall panel (1), which has a lattice bearer system (1a) that is directed towards the centre layer (3). The outside layer is made up of storey-height foamed insulating panels (2) on a polystyrene or a polyurethane base. The insulating panels are frictionally connected to the panel bearers during the concreting stage with bar clamps (6), shaped connecting parts (7) and abutment rails (8). The insulating panels may be grooved where they face the intermediate layer. The height of the panels enables them to act as an edging for the floor of an overlying storey. The standing surfaces of the panels are arranged in U-shaped base profiles (5) secured to a bottom plate.
