Abstract: Air-conditioning platforms are widely used in modern industrial workshops,thus appropriately setting methods for them are very important.In order to design the air-conditioning platform well and gain the best technical and economic effects,further study and demonstration are worthy to be done.It is briefly discussed the setting method of air-conditioning platform just in structural view of point,and is contrastsed several schemes.And it is also introduced the structural design of the platform inside a lattice grid frame.
