Double floor construction to take heavy loads, of machinery or in nuclear power stations, has hollow profiles on the supports at the lower concrete level with angled side holders for mountings

摘要

The double floor construction, to take heavy loads, has supports on the lower concrete floor level. Hollow profiles (3), e.g. of metal, are mounted on the supports as a grid, with mounted angled side holders (6) to take C-shaped profiled mountings (7). The height of the mounting is set so that its upper mounting surface is aligned with the upper surface of the hollow profile. The mountings are fastened to the angled holders by bolts (6a) and nuts (6b) with springs between them. The structure supports non-combustible floor boards (4a, 4b).
