Beamless floor (Flat slab floor): floor layer of the beam is not directly supported by the plate column, Yongzhou thin tubes, used for larger exhibition floor loads, stores, warehouses and other buildings. Column capitals structure divided into two kinds of caps and hats without column. When the floor load is small, in the form of column-free cap; when the floor load is large, in order to increase the carrying capacity of the plate, stiffness and resistance to punching ability, thin tube crimping, can set the column capitals and care in the cap across the board to reduce the board to increase the area of ??the post holder to the plate. Beamless floor column spacing is preferably 6m, a square layout. Due to the large span plate, so the thickness of not less than 150mm, thin tube manufacturers, usually 160 ~ 200mm. Beamless floor slab bottom flat, interior headroom, good lighting, ventilation, easy to use industrialized construction methods for large public buildings floor loads (such as shops, warehouses, exhibition halls, etc.) and multi-industry plant.
