U-shaped Steel Anti-falling Beam Restraint

Product Introduction

The U-shaped Steel Anti-falling Beam Restraint is an innovative product jointly researched and developed with the China Academy of Railway Sciences, suitable for standard simply-supported girder bridges and continuous girder bridges. Adhering to the design concept of overcoming rigidity with flexibility, the device only enhances the bridge's fall prevention capability but also provides damping energy dissipation functions. Its design life is comparable to that of the main structure and requires no maintenance. Through the three-stage concepts of shock absorption and energy dissipation, displacement control, and ultimate fall prevention, it ensures the safety of the bridge structure. It boasts advantages such as a sophisticated structure, convenient installation, and energy efficiency, making it suitable for large-scale application in bridges.

Based on functional characteristics, the product is divided into two categories: the U-shaped steel anti-falling beam restraint and the U-shaped steel damping anti-falling beam restraint. The former structurally employs a nonlinear variable cross-section, featuring a U-shaped structure with a low stress concentration coefficient. This design fully utilizes the deformation capability of flexible steel to effectively prevent beam falling. The latter is specifically designed for high-intensity seismic zones. It adds damping energy dissipation functions based on the U-shaped anti-falling beam fall restraint device. Relying on the Flex series of flexible steel independently developed by Newtery, it can rapidly absorb and dissipate energy during earthquakes, reducing seismic damage to the bridge and lowering the risk of beam falling.
