Construction method for integrally hoisting steel platform and integrally traversing girders layer

Abstract

The invention relates to a construction method which integrally lifts the steel platform to cross the truss layer entirely; the steps are as follows: 1. the core tube construction is processed to reach a concrete segment under the truss layer; a steel truss is mounted and a temporal stable butt joint is arranged; 2. a lattice column, a plate lifting machine support and a plate lifting machine used for crossing the truss layer are mounted; a long lead screw is connected and the platform steel girder is hung; 3. the platform girder part contacted with the truss is demounted; the steel platform is lifted to each segment and stopped in each layer for marking the height; then the platform girder is reset and the steel platform is fixed; a reinforced steel bar of the vertical segment layer is bound; a large mould plate is lifted and the concrete is cast; 4. the step 3 is repeated until the steel platform pass through the truss layer; 5. the construction method turns into the general standard construction flow. The construction method in the invention can effectively reduce the aloft work risk and furthest guarantee the construction safety; the process is simple; the construction period of the truss layer is shorten and the construction cost is reduced effectively.

Description

technical field [0001] The invention relates to an operation platform for super high-rise building cylinder construction, in particular to a construction method for integrally elevating a steel platform supported by rigid lattice columns and powered by a plate lifter. Background technique [0002] Developed by Shanghai Construction Engineering Group, the overall lifting steel platform system supported by rigid lattice columns and powered by a lifter, as a working platform system suitable for the construction of super high-rise core shells, has been successfully applied in the Oriental Pearl Tower , Jinmao Tower, World Financial Center and other super high-rise core cylinder construction. However, conventional construction methods ( figure 1 ) is unable to realize the overall lifting of the steel platform, but it is necessary to adjust the form of the stiff column and the layout of the elevator so that the steel platform can meet the construction needs in the section of the ...
