Description

Lifting appliance system suitable for mounting top plate of assembled station Technical Field The utility model relates to the technical field of subway station building construction, in particular to a lifting appliance system suitable for mounting a top plate of an assembled station. Background In the assembly process of the existing fully prefabricated subway station, due to the influence of a first concrete support, part of roof components cannot be installed in place through a portal crane, steel supports are required to be installed in advance, then concrete supports are cut off, and roof components below the concrete supports are installed after system conversion is completed; and 3, when the top plate is not assembled, a temporary surface of 10m exists under the concrete support, and the cutting operation has a large safety risk. The technical problems include that 1, construction safety and construction feasibility are directly affected, the conversion of a supporting system is easy to cause the conversion of a stress mechanism in the supporting system, 2, construction progress is directly affected, assembly work efficiency is reduced due to long-time concrete support cutting operation, construction period cost is affected, 3, potential safety hazards exist, and the arrangement and installation of a rope saw on a previous ring top plate are needed for cutting concrete support, so that the high-altitude edge working is realized. The utility model discloses an adjustable hoist of assembled subway station roof installation stress state of patent CN113200459A, the roof is assembled by prefabricated left and right two roof components and is constituteed, at least four hoisting points are distributed along the span direction of roof, including two near-end hoisting points and two distal end hoisting points, the hoist is the hoist weight dolly of operation on hoist girder track, dolly wire rope winds on the dolly capstan winch, and receive and release along with the rotation of dolly capstan winch, the hoist also includes setting up each lifting hook on the crossbeam that is the level, the lifting hook passes through wire rope one-to-one and connects on each hoisting point of roof, like this hoist, concrete support can influence the operation, need demolish concrete support, influence efficiency of construction, and there is the security risk.
