〓 PRODUCT OVERVIEW
It is composed of a steel basin, a rubber seal and a PTFE slide plate, and is suitable for load transfer and multi-directional displacement adjustment of large-span bridges.
〓 STRUCTURAL FEATURES
Three-way constraint design: the steel basin constrains the rubber body, and the compressive elastic modulus is increased to 5,000MPa.
Low-friction sliding system: The friction coefficient between the PTFE slide plate and the stainless steel plate is ≤0.03.
〓 FUNCTION AND PERFORMANCE
Function | Parameter |
Vertical bearing capacity | 10,000kN~60,000kN (EN 1337-5 standard) |
Horizontal displacement capability | ±100~1,000mm (multi-directional/unidirectional movable type) |
Rotation Angle | 0.02~0.06rad (spherical crown type adjustable angle) |
〓 APPLICATION SCENARIOS
Bridge types: continuous beam bridge, cable-stayed bridge, railway bridge (span ≥ 50m)
Engineering scenarios: urban elevated bridges, highway bridges
〓 INSTALLATION POINTS
Pad requirements: Concrete pad, flatness ≤ 1mm, embedded anchor hole diameter ≥ sleeve + 50mm.
Sliding surface protection: Apply silicone grease before installation, and the surface of the PTFE plate is prohibited from contacting oil stains.
Centering accuracy: The deviation between the center line of the support and the axis of the main beam is ≤ 5mm.
