[0012] The present invention will be further described below with reference to the accompanying drawings and working principle.

[0013] like Figure 1 As shown, a composite evacuation platform support for urban rail transit includes a threaded rod (1), characterized in that the two ends of the threaded rod (1) are connected to hinge joint A (2) and hinge joint B (3), and the hinge joint A (2) and hinge joint B (3) are respectively provided with connecting hole A (10) and connecting hole B (8); a nut (4) is fixedly connected to the middle of the threaded rod (1); and a fastening nut A (6) and a fastening nut B (5) are provided at the threaded rod (1) connected to the hinge joint A (2) and hinge joint B (3).

[0014] The threaded rod (1) is connected at both ends by the internal thread A (9) of the hinge joint A (2) and the internal thread B (7) of the hinge joint B (3).

[0015] Implementation:

[0016] Part One:

[0017] The support component measures 5cm wide, 50.5cm long, and 0.4cm thick, and is made of Q235B material.

[0018] Part Two:

[0019] Install the upper and lower bases, support components, and steel beams sequentially. When installing the upper and lower bases, ensure the center of the upper base is aligned with the standard line; when installing the lower base, the lower edge of the base must be flush with the 442.5mm chalk line; all anchor bolts or bolts must have complete washers and nuts; M12 chemical anchors require one flat nut and two nuts, and M16 connecting bolts require two flat nut and two nuts; after the bases and steel beams are installed, install the support components, connect the bases to the steel beams, and level the steel beams and step plates. The gap between the step plates of the shield tunnel evacuation platform and the structural wall should be ≤20mm, the longitudinal gap between two evacuation platform step plates should be ≤5mm, and the height difference between adjacent platform plates should not exceed 2mm; both ends of the step plates must be fully supported laterally on the platform supports and are not allowed to be suspended.

[0020] The hinges on the base and the steel beam are connected by hinge joint A (2) and hinge joint B (3). After rotating the nut (4) to make the steel beam horizontal, the fastening nut A (6) and fastening nut B (5) are adjusted to tighten the threaded rod (1) and the position of hinge joint A (2) and hinge joint B (3) to achieve support.
