(2) The original factory building column reinforcing device for newly increasing the large-tonnage crane load is simple in structure in stress, clear in force transmission, high in applicability, not only suitable for steel columns with common shapes, but also suitable for special-shaped steel columns, and good in building effect, and abundant theoretical research and standard provisions provide basis for design and calculation;

(3) This original factory building post reinforcing apparatus of newly-increased large-tonnage crane load does not destroy former factory building steel column body during the construction, so do not carry out the secondary to the primary structure and destroy, construction simple process, low cost, and concrete form can also recycle simultaneously, is favorable to the environmental protection.
