FIELD: construction.
SUBSTANCE: unified collapsible flooring comprises height-adjustable supports with support heads, a coating from identical modular elements, each one - in the form of a triangular board, and a facility to fix the specified boards in a coating plane. The board has a shape of an isosceles rectangular triangle. The facility for fixation of boards in the coating plane is arranged in the form of a spheroidal movable joint of a support head with a response groove in the central part of each board and a rigid detachable joint of adjacent edges in all boards to each other. The board is a rigid triangular frame with a thin-walled ceiling element, the lower side of the central part of which has a support lug joined with the specified frame by stiffening ribs. The groove for a support head is installed in the specified lug.
EFFECT: provision of even load at supports without necessity of thorough balancing of the base, prevention of support self-lowering under load, creation of rectangular flooring with even edges and reduced risk of traumatism.
