Situ concrete hollow floor of the economic advantages of in-situ concrete hollow floor has a light weight, filling the body, stiffness, good seismic performance, good sound effects and increase headroom storey, reduce overall construction cost, etc., in modern buildings social and economic benefits are obvious. In the provinces and cities have also been vigorously promoting and applications. Its advantages are as follows; 1 material savings (lower total cost) A. Fixed flat slab of reinforced concrete slab at a cost of 60%, reducing the cost of reinforced concrete. B. Reducing the total amount of reinforced concrete slabs. C. Due to the weight of the lower support floor columns, walls and foundation load is correspondingly reduced, so that they can reduce the member section, reduce reinforcement, saving the cost of the vertical member; D. Reduced-storey, improved headroom, reduced vertical water, electricity, wind, elevators, interior and exterior renovation and other expenses; E. Omit the ceiling, reducing the ceiling decoration and ceiling updated fee: F. Construction units to reduce the template loss, reducing the branch, Chaimo labor costs. Compared with ordinary slab structural system, increased costs of production and installation costs have filled cement thin-walled tube. Situ hollow concrete structural system, decrease costs offset polystyrene packing body, according to different spans and loads can be reduced by 5% -20% of the total construction cost. Compared with the general floor structure, reinforced concrete costs reduced by 5%, templates loss reduced by 50%, saving vertical water, electricity, elevators, air conditioning, interior wall decoration costs by 10% -15%. Yancheng Yingtian Building Material Co., specializing in the manufacture and sale of the mold hollow floor, now under the name of the application brief situ concrete hollow floor cylinder core. Situ concrete hollow floor tube core: 1 EPS filling body, hollow book 2 foam filled body wall tubes, cement hollow wall pipe 3 books, workbooks strength cement wall pipe 4, EPS cylinder core (light packing body) 5, EPS anise mandrel 6, solid polystyrene packing body 7. The drum mold 8, cylindrical solid fill volume, and many other names. Polystyrene packing body, Kunming filling body, should be days should be days of building materials by the Yancheng Building Materials Limited. Yancheng should be days of Building Materials Co.
