, In-situ concrete hollow slab: by the China Academy of Building Research editor of the "in-situ concrete hollow floor structure Technical Specification" completed in December 2004, formally implemented April 1, 2005. After the in-situ concrete hollow floor is placed according to certain rules embedded within the mold, the site pouring concrete to form the floor of the cavity in the floor. "Mold" is embedded in situ concrete hollow floor cavity for forming objects and not withdrawn. This project uses the "mold" of EPS lightweight filler rod, a cylindrical main play a regulatory role, does not participate in the force structure. When the concrete forming, to meet the design strength, the inner mold is finished "work mission." Since situ concrete hollow floor into the inner mold, thereby reducing weight, Nanning hollow floor, reduce the amount of concrete, increasing the span, lower floors, and sound insulation effect is also very good. 9. Cancel indoor pillars span increases, pillars decreased significantly save the cost (7.5 m to 8.4-9.0 m) 2-6%. 10, large precast hollow and span more than 8 meters precast hollow comparison can save the cost, reduce transportation, installation trouble 5-15%. 11, saving the cost basis, the non-load-bearing walls load-bearing walls to change or cancel the interior walls, floor relief, so that the foundation bearing the cost savings and decreased 2-4%. 12 to a non-prestressed prestressed frame structure to a non-prestressed concrete floor slabs per square meter floor space savings (steel, concrete, label) 30-50 yuan. 13, cancellation Tic Tac Toe, ribbed beams, concrete hollow floor, Tic Tac Toe, ribbed beam construction complex, instead of flat slabs per square meter floor space savings of 20-30%. 14, the second transformation since the interior wall of the non-load-bearing walls, a few years later on the indoor pattern transformation are not satisfied completely free, permanent value. 15, structural performance, light weight micro-structural properties of the floor better than solid board, increasing the relative solid board thickness, stiffness strengthened. 16, noise performance, because the floor is hollow, and its thickness increases, reducing the sound is transmitted to the upstairs downstairs, good noise performance. 17, saving pipeline installation costs no floor beneath the beam, hollow floor patents, pipeline may close under the shed installation, pipeline installation less bend, boom cut short, the material installation costs decrease 5-20%. 18, bright and spacious interior due to the floor span, there is no floor beneath the beam so that the indoor environment to achieve the best, no shadows under the shed. 19, less simple since the floor each step, 2-12% relative reduction in the actual amount of labor and employment projects. Thin-walled hollow floor | Nanning hollow floor | building materials should be days should be days by the Yancheng Building Materials Limited. Yancheng should be days of Building Materials Co. (yckxlg.com) (www.yckxlg.com) strong, credible, Yancheng in Jiangsu Province building materials processing industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas should be days of building materials will lead into the brilliant and you work for a better future!
