ADJUSTABLE BEARING STRUCTURE FOR RAISED FLOOR Russian patent published in 2015 - IPC E04F15/24 

FIELD: construction.

SUBSTANCE: adjustable structure comprises a vertical bar, at the end of which there are horizontal supports, where slots and holes are made. The bar is made of pipe-shaped couplings of a different height, the middle ones of which are separated by height into equal pipe sections of different inner diameters, a support flange rigidly fixed to them and protruding outside, along the entire outer circumference of which there is an accessory to create rotation of a coupling around a vertical axis. Pipe sections under a support flange have outer thread, and pipe sections above a support flange have stiffening ribs and an inner thread. The lower horizontal support has a flat round base with a sleeve-shaped flanging on top and an inner thread. Along the ring of the flat round base there are radial stiffening ribs arranged, forming segments, in the form of right-angled triangles, each of which is rigidly fixed by one cathetus on the flat base along the entire width of the ring, and by the other cathetus - on the outer side along the entire height of flanging, under the wall of which in each sector with the central angle 120° there is an arched slot, which partially changes into the appropriate segment between stiffening ribs.

EFFECT: increased operational reliability of a floor.
