The following information from the Yancheng hollow floor industry should be days of building materials to provide you with the hope to help my friend. Cast floor from dark beams and non-Pulling hollow floor of two parts, by the length of the hollow tube placed in the concrete slab, and asked to stay a certain gap between the two tubes. After the in-situ concrete circular holes are formed in both directions and the radius of holes hollow hollow, lightweight partition board prices become situ concrete column-free cap. Situ concrete hollow floor without beam floor is one of the key recommendation of the Ministry of Construction the latest scientific and technological achievements, with a light weight, stiffness, shock resistance, good sound insulation, increase storey headroom and reduce the project cost, etc., but because situ concrete hollow floor span, and to use more non-beam or flat beam in the form of embedded pipe and Construction Quality Control proposed new higher requirements. , 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, Nantong wall, the site pouring concrete and floor cavities formed 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 "Mold" is embedded in situ concrete hollow floor cavity for forming objects and not withdrawn.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, grc lightweight partition board, 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 wall of light, thus reducing weight, reduce the amount of concrete, increasing the span, lower floors, and sound insulation effect is also very good. grc lightweight partition board _ should be days of building materials (online consultation) _ Nantong, Yancheng Yingtian wall by the Building Material Co. provided. Yancheng should be days of Building Materials Co. (yckxlg.com) (www.yckxlg.com) Jiangsu Yancheng, a leader in building materials processing, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs . In the days of building materials should be leading the staff warmly welcome all inquiries negotiations to create the building materials should be days of a better future.
