The following describes the contents of the hollow floor Building Material Co., Ltd. Yancheng days you should offer hope to help my friend. Situ concrete hollow floor features situ concrete hollow floor construction technology is only in recent years developed Changzhi floor mandrel in the country, now mainly in the hollow floor glass fiber reinforced cement cylinder core mainly used high-strength thin-walled tube. It is based on a solid floor, by placing a certain number of its internal high-strength thin-walled tubes, thin-walled tubes with high-strength concrete to replace the part, so that you can reduce the amount of concrete and reduce structural weight. Usually buried inside a solid floor-stabilized high-strength material called a mandrel. Since stable high-strength mandrel generally closed steel barrel by the holding bracket and polymer material composition, light weight, high strength, self-fixation, convenient and effective. Situ concrete hollow floor construction technique is the use of this feature, the mold from the inside-stable high-strength thin-walled tube is fixed between floor Floor Slab on the lower reinforcement, and maintain a certain reinforcement between the beam and spacing, arranged according to a certain direction and through pouring, thus making the original into a hollow floor, solid floor, to achieve a green building, environmental protection, low-carbon development goals. 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 of Changzhi foundation slab mandrel, 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, 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, can be close to the shed next line installation, pipeline installation mandrel bend less Changzhi floor, 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. eps Changzhi mandrel mandrel _ _ day construction materials should be days by the Yancheng Building Materials Limited. Yancheng should be days of Building Materials Co. (ycytjc.com) (www.ycytjc.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!
