FIELD: construction.
SUBSTANCE: method of slab structure for construction of buildings when one or several bearing stiffening elements made of cold bended steel, elements being beams made of cold bended sheet steel and welded to sheet steel such as lining plate preferably by laser or combined welding. In slab structure bracing elements are fixed preferably by welding to one steel lining plate of sandwich type and one or several surfaces of steel lining plate of sandwich type are covered by surface coating such as concrete connecting bracing elements at lining plate of sandwich type. Invention also describes structure of slab manufactured by this method.
EFFECT: improvement of bearing capacity.
