Product Description
Bridge expansion joint, load-bearing safety bridge sidewalk, safety belt
Function: The core part that directly accommodates structural expansion, contraction, or lateral displacement.
Common Materials: Rubber (neoprene, EPDM for good elasticity and weather resistance), steel (for heavy-load scenarios like bridges), or composite materials (combining rubber’s flexibility and steel’s strength).
Typical Forms: Modular (for large displacement), strip-type (for small/medium displacement), or bridge-specific grid-type structures.
Function: Prevent water, debris, dust, and chemical impurities from infiltrating the joint gap, which could cause corrosion of internal steel bars or damage to the structure’s base.
Common Materials: Elastic rubber strips, foam rubber, or waterproof sealants (e.g., polyurethane sealants with strong adhesion).
Function: Fix the expansion device body to the main structure (e.g., bridge beam, building floor) to ensure the joint bears vertical and horizontal loads (such as vehicle weight, pedestrian pressure) without detachment.
Components: Anchoring bolts, steel plates, and embedded parts (pre-embedded in the structure during construction to connect with the expansion device).
Function: Control the direction of structural displacement (e.g., limit lateral deviation of bridges) to avoid misalignment of the expansion joint and ensure stable operation.
Common Form: Steel guide rails or rubber limit blocks.
