AI Technical Summary
When installing existing traffic poles, larger diameter poles require wider guardrails, which affects construction efficiency and has an adverse impact on the stress performance and durability of T-beam structures under extreme weather conditions.
The traffic sign pole foundation structure is adopted, and the traffic pole is connected to the beam rib of the T-beam through brackets and fastening components. The wind load is directly transferred to the beam rib with stronger load-bearing capacity, avoiding the transfer to the T-beam cantilever, thus enhancing the stress performance and durability.
This improves the load-bearing capacity and durability of the T-beams, and eliminates the need to increase the size of the guardrails, enabling rapid construction.
