Industrial prefabricatable footstep platform for screwing in front of door opening of e.g. entrance door of residential building, has footstep plate patched on support body and insulating body, which consists of extruded polystyrene foam

摘要

The platform (1) has an insulating body (3) consisting of a mechanical pressure resistant heat insulation material and arranged at a building side of a concrete support body (2). Two screw anchors (4) i.e. half-irons, pass through the insulating body, act on the support body and are distributed over width of a door opening for attachment of the platform to a structure body (6). A footstep plate (14) is patched on the support body and the insulating body, which consists of an extruded polystyrene foam. The support body is made of concrete material of quality C 35/35. The footstep plate is designed as a natural stone plate i.e. granite plate.
