Abstract

The present invention relates to an alignment device and method for a prefabricated station floor, the alignment device comprising: two rail assemblies for fixing on both sides of the floor to be installed, the rail assembly comprising an upper rail beam and a lower rail beam spaced apart and arranged in parallel, a rack being fixed on the upper rail beam along the length direction; two inner support clamps for relatively connecting the two ends of the floor; two three-axis manipulators, the ends of the two three-axis manipulators being respectively connected to the two inner support clamps; two moving assemblies for slidingly connecting the head ends of the two three-axis manipulators to the two rail assemblies respectively, the moving assembly comprising a gear meshed with the rack and a first driving member for driving the gear to rotate and causing the moving assembly to slide along the lower rail beam. The present invention solves the technical problem of low installation accuracy in the installation construction of prefabricated subway station floors in the prior art. The present invention improves construction efficiency and installation accuracy, and avoids accidents of injury caused by objects hitting the floor due to installation operations.
