H=section steel girder fireproof sheath - is mounted on sub-structures also supporting rendering carrier and insulation filler

摘要

Protective material is mechanically or manually made into a sheath, applied with the aid of a rendering support, as fire insulation for statically vital steel structures, esp. steel girders of H=section. The girders (1) is fitted with substructures (6,7), at prescribed axial interval. These serve as mounting for sheathing (5) which comprises both rendering support (8) and fireproof material (9); and for the fixture of the rendering support and of insulating material (12) filling the space (13) between sheath and girder profile stem (2) and flanges (3,4). Insulation can be of noncombustible fibre. Fixture is simplified, and sheath thickness can be precise, and capable of absorbing girder deformation.
