Building facade plate for heat and sound insulation of external facades

摘要

The elastically deformable edge zone (9,10) runs somewhat parallel to a longitudinal and/or narrow plate edge (3,4). A groove (5,6) limits the elasticity deformable edge zone, and in which the pressure piece (8) is arranged. The groove extends over the complete length and/or width of the plate edge. The pressure piece is formed as a wedge. The opposing groove side walls (13,16,18,19) enclose with one another a small acute angle, preferably of approximately 12 degrees. A groove wall adjoining the deformable edge zone runs somewhat parallel to the adjacent plate edge. The pressure piece is pre-fitted in the groove and in this position has a distance from the base of the groove (17).
