The easiest ceiling element for the manufacture of small ribbed floors of armoured concrete, made of combined three-layered plate (1), double ribbed armoured support (2) and additional armature (3), with fillers, bodoes of self-extinguishable-stiropor- (insulation material) (4) connected to a whole by a fine grained cocrete (5), according to figure 1, with embedded and then hardened concrete of the necessary mark, reducing the total mass of monolite construction of ceiling with armoured concrete, and at the same time, resolves the problem of thermal and sound insulation of the ceiling. With the combined effect of combined plate (1), armature (2), (3) and body from -stiropor-(insulation material) (4) connected with fine grained concrete, gives the element the necessary stiffness aand support for standard supporting till hardening of concrete. |
