Description
Technical Field
The utility model relates to a steel construction building consolidates and reforms transform technical field, concretely relates to steel bar outsourcing concrete reinforced structure of architectural steel structure.
Background
Beginning in the 80 th of the 20 th century, China built a batch of steel structure industrial buildings, public buildings and civil buildings. According to investigation, most of the existing steel structure buildings which are about to enter the service period are damaged in different degrees, the safety and the normal usability of the existing steel structure buildings are seriously influenced, and meanwhile, serious safety accidents such as collapse and the like occur due to improper upgrading and transformation methods. Therefore, the research on how to reinforce and reform the existing steel structure building is a technical problem to be solved urgently.
Because the steel structure has the characteristic of convenient welding, the welding reinforcement is usually carried out by adopting a section enlarging method at present. The utility model discloses a chinese utility model patent that publication number is CN109779277A discloses a steel construction factory building increase cross-section method welding reinforcement construction method, prefabricated T shaped steel by the distribution segmentation of reinforcement member on earlier according to the steel construction factory building, then with the T shaped steel handling to the corresponding edge of a wing outside by the reinforcement member and set up U type card along the line at T shaped steel, U type card one end is pasted at the edge of a wing inboard by the reinforcement member, there is the clearance the other end and the edge of a wing outside of T shaped steel, then put into wedge and hammering wedge in the clearance, make U type card will be pasted tightly by the edge of a wing outside of reinforcement member and the web terminal surface of T shaped steel, at last with the web tip both sides of T shaped steel and the edge of a wing outside welded fastening by the reinforcement member. The method adopts high-altitude in-situ reinforcement, and the U-shaped clamp and the wedge body realize the propping of the reinforcing piece and the reinforced member. However, the construction method for welding and reinforcing by the method of increasing the cross section has large damage to the original steel structure in the welding process, greatly improves the local temperature of the original steel structure member during welding, reduces the bearing capacity of the steel structure member, further causes the damage of the whole bearing capacity of the structure or the instability damage of the member, has low safety, and is difficult to control the welding quality; moreover, the reinforcing method is only suitable for reinforcing the wide-flange section steel, is not suitable for reinforcing the narrow-flange section steel, the round pipe, the box-shaped member and other members, and needs large-scale crane equipment on a reinforcing site, so that the reinforcing and modifying cost is increased.
