Yancheng Building Materials Co. should be days of economic analysis of energy-saving, the sustained and rapid development of infrastructure situ Hollow Floor two decades, it has become a pillar industry of the national economy. According to China's national conditions, forest resources are scarce, difficult to develop wood structure; for the protection of arable land, brick masonry structure also limited; steel being promoted, but the cost, durability, fire and other problems difficult to determine their popularity; concrete structure in considerably It will also serve as the main form of the building structure over a long period of time. But the concrete structure and consume a lot of energy resources, brought the steel, cement and other construction industry consume a lot of resources and issues affecting the sustainable development of increasingly urgent hollow floor manufacturers, it is worth our attention. China's cement output has ranked first for two consecutive years; in recent years is more than 10% per year rate of increase over the current annual output reached 826 million tons, accounting for about 40% of the global total. Consider not included in the statistics as a small kiln cement, but also more than that number. Housing construction on the lower amount of cement 190kg / m2, high-rise and public buildings 250kg / m2. Construction of the total annual production of about 1.5 billion cubic meters of concrete, in addition to consume 500 million tons of cement, there are 1.7 billion cubic meters of stones and 1 billion cubic meters of sand, and a number of other supporting material. After China's steel production since 1996 more than 100 million tons door to the world, continues to grow rapidly, and currently has 270 million tons. Where more than 72 million tons of steel concrete structure hollow floor, about one-third of the world. Housing construction steel consumption is as follows: Residential 50 ~ 60kg / m2, public buildings 70 ~ 80kg / m2, average 65kg / m2 or so. It can be expected that with the continued development and promotion of future construction steel, demand for steel will surge. Situ concrete hollow floor construction process technology Construction technology of cast concrete hollow floor is more complex, process more, but every step of the key hollow floor, directly affect the quality of good or bad floor. General steps as follows: Surveying → erection module installation foot end support system → Templates → elastic line on the template, determine where the mandrel, and the location of the pipeline steel plate embedded in and play good ink line → lashing plate steel, Set steel protective layer pads → installation mandrel die holder and embedded pipeline → lashing longitudinal and transverse ribs underlying reinforcement steel mesh → acceptance → installation, fixed mandrel → lashing surface reinforcement, good reserve embedded → Erection Overhead sidewalk construction, installation duct → → pouring concrete curing concrete, form removal. Hollow floor picture, Changzhou hollow floor, building materials should be days 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!
