How big is the square column of the steel structure of the glass sun room?

Generally, according to the requirements of floor load, secondary beams should be set between the main beams, and the spacing can be 3 ~ 4m. The layout of frame column network should be considered from four aspects: meeting the requirements of production technology, meeting the requirements of building plane, reasonable structure stress and convenient construction. Generally, columns are set at the intersection of vertical and horizontal axes of buildings to reduce the influence of column network on the use function of buildings. Column network is also related to beam span. Larger column grid size can gain more space, but it will increase the cross-sectional size of beams and columns, which should be considered comprehensively in combination with building needs and structural cost. When the column network is arranged, it should be considered that the internal force distribution of the structure under vertical load is uniform and reasonable, and the material strength of each component can be fully utilized. At the same time, try to facilitate and speed up the construction progress and reduce the project cost. Square column network and rectangular column network are the basic column networks commonly used in multi-storey and high-rise frame structures, and the column spacing should be 6 ~ 9m m. After the column network is determined, the beam network can be naturally arranged according to the column network. The main beam of the frame should be arranged between the columns of the frame and rigidly connected with the columns according to the direction of the frame.
