Sound separation wall construction for use in building, has S-shaped dual profile column extending over specific width, which is same or fractionally larger than internal dimension of U-shaped connection profile

摘要

The construction has an S-shaped dual profile column (20) extending over a specific width by distal fastening flanges (21, 22) in an expanding condition. The width is same or fractionally larger than an internal dimension (A) of a U-shaped connection profile (15) such that the column is clampingly inserted into the connection profile between connection profile flanges due to spring effect. The column includes two U-shaped individual profiles (30, 31) with bases (32) extending in a longitudinal direction, where the individual profiles are made of sheet metal. An independent claim is also included for a method for manufacturing a sound separation wall construction.
