Multi-section universal assembly-type reinforcing device for steel structure and its application method

Abstract

The invention particularly relates to a multi-section universal fabricated reinforcing device for a steel structure. The multi-section universal fabricated reinforcing device comprises a pair of symmetrical fixtures. The fixtures are composed of top plates, side plates, end plates, clamping plates, reinforcing plates, nuts and bolts; the side plates are perpendicularly welded to the two sides of the top plates; the end plates are perpendicularly welded to the ends of the top plates, and the end plates and the side plates are perpendicularly welded into a groove-shaped member; the multiple paired adjacent clamping plates are distributed on and welded to the inner side of the groove-shaped member at equal distances in the longitudinal direction; a clamping groove is formed between every two paired adjacent clamping plates; and the reinforcing plates are inserted into the clamping grooves. The multi-section universal fabricated reinforcing device is used for reinforcing a rod of the steel structure, the principle is simple, the force bearing state of an original structural system is not changed, and the construction scheme is greatly simplified; the reinforcing device does not has the rigid weak axis so that the outer plane rigidity of the reinforced member can be strengthened in multiple directions, and the reinforcing effect is good; the modular assembling connection mode is adopted so that the multi-section universal fabricated reinforcing device can be flexibly used in construction, and the construction process is greatly simplified; and the structure is simple, mounting and demounting are convenient and fast, construction is easy, repeated turnover using can be achieved, the construction cost is effectively reduced, and the construction efficiency is greatly promoted.

Description

technical field [0001] The invention relates to the field of steel structure installation, in particular to a steel structure multi-section general assembly reinforcement device and a method for using the same. Background technique [0002] At present, the steel structure space structure system has been favored by more and more people due to its good mechanical properties and geometric flexibility, and is widely used in various long-span engineering fields such as stadiums, railway stations, and exhibition centers. . During the installation and construction of this type of structure, due to the difference between the construction state and the design state of the stress state, some members often cannot meet the bearing capacity requirements. The traditional method is usually to change the installation and construction plan or replace such members. Therefore, it often brings a lot of inconvenience to the actual construction. Contents of the invention [0003] The present ...
