Transportation and installation device and method for full-composite assembled reverse operation construction subway station prefabricated middle plate

Abstract

The invention discloses a mechanical transportation and installation device for a full-composite assembled reverse operation construction subway station prefabricated middle plate. An underground wallis embedded with a steel structure clamping groove and a prefabricated middle longitudinal beam reserved protruding tongue and groove at the elevation position of the middle plate, and used for lifting and placing of the prefabricated middle plate; concave lower clamping grooves extending longitudinally along a subway station are preformed in the steel structure clamping groove and the prefabricated middle longitudinal beam reserved protruding tongue and groove correspondingly, and convex upper clamping grooves extending longitudinally along the subway station are preformed in the corresponding positions, at the two ends, of the lower part of the prefabricated middle plate; and a sliding lifting device is installed in a gap composed of the lower clamping grooves and the upper clamping grooves, and can support and lift the prefabricated middle plate and drive the prefabricated middle plate to move longitudinally along the subway station. Thus, the problems of difficult transportation and installation of the full-composite assembled reverse operation construction subway station prefabricated middle plate are solved.

Description

technical field [0001] The invention belongs to the field of underground engineering, especially subway stations, and specifically relates to a device and method for mechanized transportation and installation of prefabricated mid-slabs in subway stations of a full-composite assembly type upside-down construction. Background technique [0002] Existing underground structure engineering, such as subway station structure, has two structural forms, prefabricated underground structure and full cut-and-cast underground structure, but both have their own defects. To overcome these problems, a fully composite fabricated subway station structure was developed. [0003] However, the following problems exist in the construction process of the fully composite prefabricated subway station: [0004] (1) Full-composite prefabricated upside-down construction In the construction process of the subway station, the longitudinal beams and roof slabs of the station roof are hoisted first, and t...

AI Technical Summary

Problems solved by technology

[0008] Aiming at at least one of the above defects or improvement needs in the prior art, the present invention provides a prefabricated mid-slab mechanized transportation and installation device for a full-composite assembly-type upside-down construction subway station, which solves the problem The prefabricated middle plate is difficult to transport and install, especially it can be composed of only four sliding jacks, two sets of chutes, hoist and handwheel, the equipment is simple, the installation speed is fast and the precision is high
