Abstract

The utility model relates to an evacuation platform, which comprises a platform face and a folding support structure fixedly connected with the platform face on the lower portion. The platform face comprises a plurality of longitudinal beams arranged adjacent in the longitudinal direction. The support structure is fixedly connected with the lateral wall of a tunnel and fixedly connected with the platform face through a plurality of cross beams transversely arranged at intervals. Each longitudinal beam is a straight tube with the cross section in a square, trapezoid or circular shape. A plurality of pins respectively and vertically penetrate and locate all the longitudinal beams longitudinally arranged to form the platform face. Each cross beam is a straight tube with the cross section in a square shape, the cross beams and the platform face are fixedly connected through bolts. Basic structures of the longitudinal beams of the platform are changed, so that the platform face can be connected with the support structure only through the bolts. Use and fabrication of special connection elements between the platform face and the support structure of an existing evacuation platform are avoided so as to save material cost.
