FIELD: construction.SUBSTANCE: load-carrying floor is made as a single soil structure of box-shaped cross section, the upper and lower shelves 2 of which form slabs of the load-carrying floor, and longitudinal 3 and transverse 4 walls separate the load-carrying floor into separate rooms. Height Hop of door openings 5 in walls of the load-carrying floor without strengthening of the link part makes not more than 2/3 of wall height H, and height Hof window openings 6 in walls of the load-carrying floor without reinforcement of the link and window sill parts makes not more than 2/3 of wall height H. Door 5 and window 6 openings in walls of the load-carrying floor without reinforcement of the link or window sill part are located from the supports of the load-carrying floor at the distance B of at least 1/8 of its span L. The width D of door 5 and window 6 openings without reinforcement of the link or window part that are within the limits of the extreme thirds of the spans does not exceed their height of accordingly Hand H, and width of openings in the middle part of the span - two heights Hor H. Widths of piers C between openings in walls of the load-carrying floor made without their reinforcement make at least their heights H.EFFECT: invention makes it possible to increase span of a covered space and to reduce consumption of structural materials.6 cl, 1 dwg |
