Universal type static load crack resistance test rack for prefabricated track slab

A general type static load crack resistance test rack for prefabricated track plates comprises a base, height adjusting short columns, a counter-force frame, a jack and a sensor, the base is in a square shape and is formed by welding four pieces of I-shaped steel, a plurality of steel plates with bolt holes are welded to top flanges of the I-shaped steel on the periphery, and transverse brackets are installed on the steel plates on the transverse opposite sides of the base. Longitudinal brackets are installed on the steel plates on the opposite sides of the base in the longitudinal direction, the lower portions of height adjusting short columns are connected with the steel plates on the base through bolts, the upper portions of the height adjusting short columns are connected with a reaction frame through bolts, and jacks and sensors are installed at the positions, corresponding to track plate track bearing tables, of the reaction frame. The universal track slab static load crack resistance test rack is simpl
