Common problems after long-term application of the antenna

Bar through years of weathered, present different degree of disease, such as the steel structure coating degradation, the structure of the marker rod bolt corrosion, deformation, lack of the loose bolts and rivets, the structure of the weld and the bearing fatigue crack, stress value, break through the original planning at outsourcing

 sign after years of weathered, present different degree of disease, such as the steel structure coating degradation, the structure of the marker rod bolt corrosion, deformation, lack of the loose bolts and rivets, the structure of the weld and the bearing fatigue crack, outsourcing concrete stress value, break through the original planning foundation concrete crack damage and crack, foundation pillar straight overrun, beams interference degrees overrun situation & quot; 。 These diseases affect the way operational safety, elevated road and the ground road traffic and pedestrians to bring security hidden danger. Disease is as follows. 1) Mark pole foundation anchor bolts rust appearance. 2) Lack of outsourcing bar foundation concrete, crack, breakage, root of concrete damage. 3) Bar steel structure corrosion. 4) Between deformation of bar steel members, the column brace weld cracking. 5) Loose foundation anchor bolts, spring gasket is missing. 6) Corrosion or cracking. 7) Column corrosion or cracking. 8) Beam deflection, support the vertical degree does not meet the standard requirements.
