The Application of Grid-Frame Structures with Specially Shaped Columns in Energy-Saving House Using Phosphorus Gypsum Li Li1, a, Kejian Ma2, b, Huagang Zhang2, c and Yaqin Lu2, d 1College of Civil Engineering, Guizhou University, Guiyang, Guizhou, 550003, China 2The Research Center of Spatial Structure, Guizhou University, Guiyang, Guizhou, 550003, China alilidiyi@163.com, bmakejian@163.com, czhanghuagang@163.com, dluyaqin@163.com Keywords: Grid-Frame Structure; Specially Shaped Column; Rib Column; Rib Beam; Phosphorus Gypsum; Energy Saving Abstract: The feature of the concrete grid-frame structure with specially shaped columns is the frame beams and specially shaped columns in the walls were divided by rib beams and rib columns, then the rib beams, the rib columns, the frame beams and the specially shaped columns together constitute the grid-frame structures with specially shaped columns.
In addition, the floor (roof) structure is a large plate structure which can be supported around, so the quantity of the foundation engineering can be reduced; Moreover, in the structure, the use of big space with demountable partition can be realized, so it is applied to small high-rise residential buildings.
