COMPOSITE FLOOR Russian patent published in 2001 - IPC

FIELD: construction engineering; replacement, repair, and rebuilding of floors in old buildings with brick, slag-block, or reinforced concrete walls. SUBSTANCE: composite floor has longitudinal bearing beams with supporting horse scaffolds and floor with heat insulation. Longitudinal bearing beam is made in the form of wood case accommodating longitudinal steel insert; the latter is joined with wood case by means of horizontal tubular steel dowel pins passed through wood case and insert; mentioned dowel pins carry bolts mounting supporting horse scaffolds. Floor is made in the form of panel with heat insulation and is framed over its perimeter to mount facing panels protruding over entire perimeter beyond its framing and joined to the latter by means of wood rabbets installed flush with ends of facing panels over entire perimeter of panel. Panels are supported by horse scaffolds of longitudinal bearing beams through two opposite ribs; space between bearing beams, framing, and panel rabbets is filled with foamed heat- insulating material that may be made in the form of water-repellent porous insulation covered with polyethylene shrinkable-film sheath. Panel framing is provided with diagonal ribs tilted through 35-55 deg. to longitudinal side of framing; diagonal ribs of two panels adjacent through entire beam length are facing each other. EFFECT: reduced labor consumption while desired stiffness of structure is ensured. 6 cl, 2 dwg
