Problems solved by technology
[0002] In the related art, steel component strengthening methods can be divided into the following four categories: (1) method of enlarging component section, this method cannot adopt welding connection for structures with flammable materials around and cold-formed thin-walled steel components, and adopts If the method of sticking steel or sticking carbon fiber boards is used for reinforcement, the construction is difficult and the period is long, especially when working at heights to strengthen long-span roof components, the construction difficulty and period will be further increased; (2) Change the structural stress system method, this reinforcement method (3) Applying prestressing method, this method has high requirements on construction technology, and it is difficult to apply prestressing force when working at heights, so it is not suitable for the reinforcement of ordinary structures; (4) Prevent buckling of cold-formed thin-walled steel Reinforcement method, because it is impossible to add ribs to the flange web of the existing structural members, and it is also impossible to add partitions to the cold-formed thin-walled purlins with braces, and there is no clear and simple calculation method for this reinforcement method , so it is not suitable for structural reinforcement design

The invention discloses a steel member reinforcing structure which comprises a steel component to be reinforced and a reinforced steel component. The reinforced steel component is arranged on the steel component to be reinforced. The reinforced steel component exceeds the steel component to be reinforced in at least one of the upward direction and downward direction. The steel member reinforcing structure is large in rigidity, large in bearing capacity, small in construction difficulty and quantity of work, low in reinforcing cost and wide in application range. Furthermore, the reinforcing process can be finished under the condition that the steel component to be reinforced is loaded, and the use influence on building facilities is small.
