Now, with the development of technology, materials are constantly updated and innovation. Many new building materials are used, for example, is one of the hollow floor, here we come to the hollow floor offerings. Hollow Floor Products is a new environmentally friendly energy-saving products, in line with the law of industrial ecology and the circular economy development. Situ concrete floor is mainly flexural members, which consists of the tension zone and compression zone structure, tension and stress is concentrated in two parts to form a cross-sectional moment; the middle-section against the force of the impact is very small. Situ concrete hollow floor superior seismic performance instance hollow floor excellent seismic performance has been truly reflected in the 2008 Wenchuan earthquake. With the rapid development of China's national economy, construction projects in the field of new technologies, new materials are emerging, people building function requirements are increasingly perfected to meet the modern building on the story, self-respect, a large space, free interval requirements, it developed a variety of newer, more suitable, economic performance and better floor system. Building Materials Co., Ltd. Yancheng Yingtian share with you about the in-situ concrete hollow floor structure design method, Yancheng Yingtian Building Material Co., which sells products hollow floor mandrel hollow floor, welcomed the new and old customers here. ] A design based on "in-situ concrete hollow floor structure Technical Specification" (CECS175: 2004). "Situ concrete hollow floor" (O5SG343) "concrete design specification for structures" (GB 50010-2002) "civil air defense basement design specifications "(GB 50038-2005) 2. Design software design can be used PKPM, STRAT software, Lizheng toolbox existing structural design software, may also hand count. 3. Design methods (1) side of the support plate for single board, if the compression zone height is less than the height of the hollow plate flange cast hollow floor, is calculated according to the heart of the way and so thick plate reinforcement calculation, such as compression area height greater than the height of the hollow flap hollow floor advantage, you need to press the actual "work" -shaped cross-section Reinforcement. For bi-directional board, in the calculation process, should pay attention to the concrete compression zone plate should be controlled within the height range of the flange, when satisfied, should be increased by adjusting the height of the top flange thickness. Sales hollow floor, Shenyang 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!
