BUILDING WITH LARGE-SPAN ROOM Russian patent published in 2014 - IPC E04B1/00 

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 H_w of 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 H_op and H_w, and width of openings in the middle part of the span - two heights H_op or H_w. Widths of piers C between openings in walls of the load-carrying floor made without their reinforcement make at least their heights H_op.

EFFECT: invention makes it possible to increase span of a covered space and to reduce consumption of structural materials.
