Common engineering problems of large-span playground roof structures in primary and secondary schools and introduction to new floor system
In recent years,with the continuous changes in the new architectural form and functional layout of primary and secondary school buildings in Shenzhen,school users have reported that there are many engineering problems in the large-span playground roof structure of new buildings.The corresponding solutions and methods were proposed,and a new high-efficiency and high-comfort large-span roof structure was recommended,which provides a new structural solution for this kind of buildings.Further through the data comparative analysis of the actual case,the advantages of the structure were explained,such as the structural system will convert most of the flexural shear force into axial force,which improves the utilization rate of structural materials,reduces the engineering quantity and greatly reduces the engineering cost,and because the bending and shear deformation of most of the components is also transformed into axial deformation,the overall deformation of the structure is better controlled,and the comfort level of the roof has also been greatly improved,so it is a very suitable for the structure of the large-span playground roof.In order to promote the structure well,the main points of the design and construction of the large-span structure and the countermeasures to avoid roof cracks were put forward at last.
