Improving the manufacturability of floor slabs by pre-installing elements that partially replace reinforced concrete and formwork

The article discusses well-known and perspective constructive technological systems for the installation of monolithic precast-monolithic floor slabs civil industrial buildings. It shows examples expediency using all kinds inserts made plastic other light materials products replacing a part heavy reinforced concrete. An original resource-saving method with simultaneous increase in degree their construction readiness is proposed. This effect achieved by reducing own weight use permanent formwork. Reduction slab ensured volumetric lightweight trapezoidal or rectangular inserts, preferably expanded polystyrene, during its installation. formwork will eliminate need subsequent performance labor-intensive finishing insulation works. To confirm effectiveness proposed installation, operation two was modeled LIRA SAPR computing complex - concrete innovative solid slab. Having analyzed calculated forces, deformations corresponding consumption reinforcement concrete, comparative indicators were obtained typical As result, significant savings material cost have been proven.
