Introduction and Construction Guide for 80-Type Tooth Plate Expansion Joint

80-Type Tooth Plate Expansion Joint is an expansion device suitable for small and medium-sized bridges, urban viaducts, and highways. It adopts a tooth plate steel structure, featuring high load-bearing capacity, smooth driving, and excellent durability. It is suitable for bridge projects with an expansion capacity of 0–80mm.

1. Overview of 80-Type Tooth Plate Expansion Joint

• Model Meaning: The number "80" indicates that the maximum expansion capacity of this expansion joint is 80mm (±40mm).
• Applicable Displacement Range: 0–80mm (suitable for displacement caused by temperature changes, Direct Sales of Plate Rubber Expansion Device RBKF 80mm Expansion Capacity, Price of 80-Type Tooth Plate Expansion Joint concrete shrinkage, and creep).
• Structural Features:
• Upper Tooth Plate (movable end) and Lower Tooth Plate (fixed end) interlock alternately to accommodate expansion and contraction deformation.
• High-strength steel (Q355B or higher), wear-resistant and impact-resistant.
• Rubber Waterstop to prevent rainwater from seeping into the beam end.
• Main Applications:
  • Small and medium-span bridges
  • Urban interchange bridges and viaducts
  • Highway bridge joints
