The following information from the industry should be days of Yancheng Building Materials Co. provides you Lingyuan cm hollow floor, we want to help our friends in Lingyuan cm hollow floor, also welcomed friends call contact picture on us. Hollow floor is placed according to certain rules after the mold cavity formed by pouring concrete floor. Hollow floor slabs cover technology has so light weight, stiffness Lingyuan cm hollow floor, reduce floor noise, enhance overall seismic structure, prevent leakage, etc. floor. By using unbonded prestressed technology in the floor construction, and in the construction of the light-mold material embedded in the concrete cast, so as to achieve enhanced rigidity and reduce the floor slab weight, big span purposes. Building Materials Co., Ltd. Yancheng days should share with you about the content: quality situ Hollow Floor size to allow deviation from the specified requirements: Item Tolerance (mm) length L≤500 ± 8L> 500 ± 10 sectional size D≤300 ± 5D> 300 ± 8 end surface flatness D≤300 ± 5D> 300 ± 8 filling body flatness L≤500≤5L> provisions 500≤8 physical and mechanical properties: Item Specification Line Density (kg / m) 80≤D <200≤1.8200≤D <350≤3.5350≤D <500≤5.5500≤D <650≤8.0650≤D <800≤10.0 volume of water absorption (%) ≤8 compressive load (kg / m) ≥100 anti-vibration shock and vibration 1min.
