Situ concrete hollow floor in line with the requirements of building a green energy efficient building national advocacy, have good development prospects. Hollow floor underground garage can effectively increase the clear height, reducing the amount of earth excavation of the basement foundation, reduce the amount of concrete pouring to reduce the structural weight, flame retardant composite housing prices, improve the bearing capacity and seismic capacity of the basement, while increasing Late basement roof green earth backfill capacity and enhance community greening effect, reduce the overall project cost. Due to the reduced weight, hollow floor slab solid than the corresponding column caps required is reduced a lot, substantially flat bottom plate for handling and various pipeline next to the library roof provides a convenient installation. But the hollow floor in the actual construction process, there are many difficult issues, further research is needed to optimize resolved. Bi thin square box hollow floor slab that is substituted intermediate inefficient arranged according to certain rules of concrete from the cavity to form a two-way shear stiffness and flexural rigidity of the same two-way hollow floor. Its substantial evacuation of concrete, Anyang flame retardant composite cabinet, reduce floor weight, flame retardant composite cabinet, increased steel sectional neutral axis to distance, thereby significantly increasing the bending stiffness of the floor, to reduce steel consumption. Bi thin square box hollow floor frame beams can be bright beam can also be used the same as the thickness of the dark flat beams. When the height of the Ming Liang is not less than twice the thickness of the floor, according to the beam bi-board computing, or should consider the impact of hollow plate stiffness; when dark flat Beam relatively high cross-hours (generally less than 1/25) should by no Beam Slab calculations, Jiyuan flame retardant composite cabinet, or may be flat beam cabinet structure calculation system, but the dark flat beam construction must meet the relevant specifications. Flame retardant composite housing prices, the Thai Star Building Materials (certified), flame retardant composite housing is provided by Tang Yin Thai Star Building Materials Co., Ltd. Tangyin Thai Star Building Materials Co., Ltd. (www.tytxjc.com) is Anyang, other leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Thai Star Building Materials in leadership with the staff warmly welcome all inquiries negotiations to create the Thai Star Building Materials better future.
