The large span buildings comprising no ordinary beams and columns are formed of vertical load-bearing composite wall-panels and composite floors, both comprising two concrete layers interconnected by steel strip webs. The stiff horizontal plane formed of assembled roof/ceiling units, supported by wall-panels, connected to both gables restrains transversal movement of longitudinally arranged wall-panels attached tops, bracing them simultaneously against sideway and lessening their buckling lengths. Floors, if any applied, being rigidly connected to the vertical panels additionally improve stability of the global structure. Hereby invented composite wall-panel and floor are adapted to the same purpose. The global structure, being braced in that way, behaves as a rigid box made of slender panels.
The composite, wall-panel (1) characterized in that comprises the two distinctly wide and thin concrete layers (2) and (3), both reinforced substantially with two steel wire mesh layers (5), being interconnected continuously throughout entire length of the panel by at least two thin steel strip webs (4) so that the wide gap is formed between them filed partially by thermo-insulation (10) inwardly adhered to inner concrete layer with the rest of the space (11) used as an air ventilation whereby the strip-webs (4) are anchored to both concrete layers through plurality of welded along their edges arranged steel loops (7) containing holes (9) into which short steel rod anchors (8) are inserted keeping the distance between mesh layers, through which additional longitudinal reinforcing bars (6) or prestressing strands are conducted.
The building construction of composite load-bearing vertical wall-panels (1) and composite roof-ceiling units (13) which may comprise few floor units (29), characterized in that wall-panels (1) aligned and rigidly fixed as cantilevers to strip precast foundations (18) with longitudinal sockets (22) arranged along the perimeter of the building, whereby the widths of wall-panels (1) exactly coinciding with widths of floor-ceiling and floors units (29) ensure in that way precise coincidence of connecting details, so that the building with all flat inner surfaces, comprising no either columns nor beams is achieved.
The lateral bracing mechanism principle for the self-stable buildings constructed of composite load-bearing vertical wall-panels (1) and composite floor-ceiling (13) and roof units (29) as claimed in clime 4, characterized in that wall-panels (1) mounted and rigidly fixed temporarily as cantilevers after being attached with their tops to the stiff horizontal plane (51) formed of all applied roof-ceiling plates (13) interconnected along their adjacent edges by details (54), became laterally restrained against sideway with their buckling length significantly reduced, by joining the ending plates of roof units along their contacts to gable wall panels bracing in that way the whole structure and ensuring its lateral stability.
