1. Background introduction of frame type shear hinges

The frame type shear hinge is applied at the connection joint of two adjacent prefabricated floating slabs in the track system to reduce the vertical displacement of the track and share the shear force borne by the steel rail at the crossing joint, so as to coordinate the deformation of the slab. The use of integral frame shear hinges can enhance the integrity of the floating slab system, while improving its shear, bending, and torsion resistance performance.

Increase its vibration mass and improve the vibration reduction effect of the floating plate.

Shear hinges are important components of a structure that transfer shear forces between adjacent floating slabs. Shear hinges connect the floating slabs and provide a certain degree of stiffness to reduce vertical displacement of the track.

3. Materials and technical indicators of frame shear force

The frame type shear hinge has excellent overall performance and high stiffness in resisting shear, bending, and torsion. By optimizing design and calculation, its resistance

The shear stiffness Kz can reach the tenth power or higher, and the bending stiffness Kb and torsional stiffness Kn can also reach the eighth power of ten, respectively

The smoothness and stiffness of the floating slab track operation are greatly improved with a magnitude of ten to the ninth and above.
