Lightweight building element for building wall reinforcement of existing objects, as well as wall reinforcement from lightweight building elements

摘要

The lightweight building unit (1) comprises a closed shroud (7) of weather-proof material e.g. steel sheet and a filling from two layers (9,10) of different composite materials. The layers are arranged parallel to front (5) and rear wall (6) of the lightweight building unit. A layer (9) is a wood composite material and another (10) is an aluminum composite material. The filling is formed by three layers of wood composite material plates (10) and two layers of aluminum composite material plates (9) of arranged alternatively. An independent claim is also included for building wall reinforcement in an educated manner by lightweight construction elements.
