Beamless floor in order to improve the characteristics of punching shear at the flat top of the column, often set up in the capitals column caps. Beamless floor using column net usually square or nearly square, light panels, this is more economical. Commonly used column grid size of about 6m. Flat slabs can get a larger interior space, suitable for floor hall, a large hall where space is like. In real life there are seismic requirements of the building are not using flat slabs. Because of the earthquake disadvantage. 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, 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, Taizhou wall, its thickness has increased, reducing the sound is transmitted to the upstairs downstairs, good noise performance. 17, saving pipeline installation costs no floor beneath the beam, can be close to the shed next line installation, pipeline installation less bent, shortened boom, 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. grc lightweight partition board, Taizhou wall, 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!
