Prefabricated bent cap of urban rail transit bridge T type mound

The utility model provides a prefabricated bent cap of urban rail transit bridge T type mound, is a support connecting elements that supports superstructure, the horizontal bridge of prefabricated bent cap is applicable to 6-12m to the width. The leading features of the prefabricated bent cap of T type mound shows its special interface connection structure: adopt the connected mode of steel construction, combine together through steel sheet about pre-buried and steel shear force tenon nestification to adopt the connected mode of vertical prestressing and steel sheet annular welding seam. Prefabricated bent cap and pier stud interface connection structure adopt the connected mode of steel construction, can full play interface position steel construction tensile, shear, the characteristic of bending resistance and antifatigue, can be better resist static load, mobile load and earthquake masterpiece with eccentric bending moment and shear force down, comparatively safe reliably. The utility model discloses can adopt liang chang prefabricated, on-the-spot hoist and mount and welded construction process, the bent cap dead weight is less, and is not high to road transport condition along the line requirement, can popularize and apply in larger scope.
