Pre-stressed concrete track slab of slab-type ballast-less track
Provided in the disclosure is a pre-stressed concrete track slab of slab-type ballast-less track, which includes a slab body (1), on which fastening embedded casings (4) are arranged. At least one row of longitudinal common steel bars (11) and at least one row of transverse common steel bars (12) are arranged in the slab body (1) along a length direction and a width direction. The longitudinal common steel bars (11) are insulated from the transverse common steel bars (12). At least one row of longitudinal pre-stressed steel bars (7) and at least one row of transverse pre-stressed steel bars (6) are fastened in the slab body (1) along the length direction and the width direction through anchor backing plates and fastener devices (8). In the pre-stress directions of the longitudinal pre-stressed steel bars (7) and the transverse pre-stressed steel bars (6), it is post-tensioned in both directions or it is pre-tensioned in one direction and post-tensioned in the other direction. Limiting structures (5) and grounding terminals (10) are also arranged on the slab body (1). The pre-stressed concrete track slab has the characteristics of light structural dead weight, small structure height, low manufacturing cost and deformation resistance.
