Description

Technical Field

[0001] The utility model relates to the field of construction, in particular to a reinforcement structure of a bent rod and a device thereof. Background Art

[0002] Driven by market demand, my country's steel structure industry has developed rapidly. While the large-span space structure is booming, it has also caused more and more structural safety problems. For example, rods often bend and deform during transportation, construction, use, or extreme weather conditions (wind, snow, temperature loads exceeding the design value). Therefore, it is of great significance to reinforce components with insufficient bearing capacity. When the bending is small, hot processing correction, external steel casing or angle steel can be adopted. When the bending deformation is large and cannot be corrected, the reinforcement method of external steel casing or angle steel is relatively difficult. In addition, the above-mentioned hoop reinforcement method is only applicable to the reinforcement of insufficiently stable compressive rods, and is not applicable to the reinforcement of unsatisfactory tension rods. Therefore, a reinforcement structure suitable for rods with large bending deformation is needed in the project. Utility Model Content
