Non-deformable supports for jamb or reveal openings

摘要

The support comprises a single or multi-layered flat body (1) with one or more bores (2). Under the stressed area (5) the jambs (3) and bolts (4) are supported by one or more support weldings (6) or one or more support bolts (7) or one or more support sleeves (8). First, the outer layers may be provided with one or more bores and then are welded together to form a locally fixed connection with the centre or next layer. The bores are filled with high strength welding material. The zone under the jamb hole is reinforced.
