Main material node is the connecting portion of main material with main material, is the stressed key position of whole steel tower, and the good connection of node is the key that steel tower is reinforced success.The reinforcing mode of steel tower is that angle steel increasing section in parallel is long-pending on original main material at present, and then increase component strength reaches the object of reinforcing steel tower.The reinforcing joint plate that adopts this kind of method to increase ring-type at origin node links together new, old member.There is joint reinforcing plate manufacturing process complexity, the shortcoming of installation and maintenance difficulty in this kind of method.
Utility model content
For addressing the above problem, the utility model is for ZGU2(7727) 110 kilovolts of double loop straight line towers, the main material node structure of angle steel tower of power transmission line after a kind of reinforcing is proposed, adopt the method for welded lap to complete the reinforcing of steel tower node location, avoid the complicated procedures of forming of design and installation ring node plate, and this kind of ruggedized construction good looking appearance, save material.
To achieve these goals, the utility model adopts following technical scheme.
The main material node structure of angle steel tower of power transmission line after a kind of reinforcing, comprise main material, reinforcing angle and bolt, main material comprises upper and lower main material, on upper and lower main material, be welded with respectively reinforcing angle I, on two reinforcing angle I, be welded with a reinforcing angle II, gap between reinforcing angle I and main material, the weather-resistant glue of sealing use is filled up at the gap place between reinforcing angle I, reinforcing angle II; Reinforcing angle I, reinforcing angle II and main material reinforcing area surface spraying have zinc content to be greater than the corrosion-resistant finishes that 90% cold galvanizing spraying forms.
Described reinforcing angle I is than the wide 0-8mm of length on main material angle steel limit, and selected reinforcing angle I is than the large 0-5mm of thickness on main material angle steel limit.
Described reinforcing angle II is than the wide 0-6mm of length on main material angle steel limit, and selected reinforcing angle II is than the large 0-5mm of thickness on tower leg main material angle steel limit, and length is 200mm-500mm.
The beneficial effects of the utility model: by appropriate design ruggedized construction, adopt the method for welded lap to complete the reinforcing of steel tower node location, avoided the complicated procedures of forming of design and installation ring node plate, and this kind of ruggedized construction good looking appearance, save material.The employing of node location overlapping technology can weaken stress hysteresis effect, increases steel tower and reinforces strengthening effect.Joint reinforcing region is sticking structure in angle steel, and institute takes up space little, is conducive to step on tower upkeep operation.
