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
The present invention relates to a kind of job platform of super highrise building cylindrical shell construction, especially a kind of is that supporting, Lift-slab machine are the job practices of the integrally hoisting steel platform of power by the stiffness lattice column.
Background technology
Develop by Shanghai construction engineering group, by the stiffness lattice column is that supporting, Lift-slab machine are the integrally hoisting steel platform system of power, as a kind of job platform system that is applicable to the construction of superelevation layer nuclear core cylindrical shell, be successfully applied to high-rise nuclear core cylindrical shell construction such as Oriental Pearl, Jin Mao Tower, Global Finance center.Yet, run into include the stiffness truss after, conventional job practices (Fig. 1) is to realize integrally hoisting steel platform, and need stiffness cylindricality formula and Lift-slab machine arrangement be adjusted, so that the steel platform satisfies the construction needs at cylindrical shell girders layer section, and not configuration template, pin hand separately.
Summary of the invention
The present invention will solve after running into the stiffness truss, makes the steel plateform system can be in the whole technical problem that promotes of girders layer, and a kind of integrally hoisting steel platform and integrally traversing girders layer job practices is provided.
For solving technical problem of the present invention, the technical scheme that is adopted is as follows:
A kind of integrally hoisting steel platform and integrally traversing girders layer job practices, concrete steps are:
1. core tube construction concrete segmentation to girders layer, and steel truss is installed and is provided with interim stable to support;
2. lattice column, Lift-slab machine carriage and Lift-slab machine that girders layer is used were installed, and the spreading screw mandrel is hung the platform girder steel;
3. remove the landing beam parts of colliding, promote steel platform to each segmentation and stop a layer absolute altitude, then landing beam is resetted and fixing steel platform with truss, and the reinforcing bar of a vertical section layer of colligation, large form and fluid concrete promoted;
4. repeat third step to passing through girders layer;
5. enter the conventional criteria construction process.
After above-mentioned the 4th step, before entering the conventional criteria construction process, lattice column is converted to the typical floor lattice column, and Lift-slab machine is converted to typical floor construction state.
The invention has the beneficial effects as follows:
1. effectively reduce the work high above the ground risk, ensured construction safety to greatest extent
Integrated lifting steel plateform system puts in place according to successively whole lifting of each vertical section of girders layer, the solid broad operation platform and the operating environment of complete closed are provided, avoided simultaneously the steel platform being split the combination operation in the high-altitude, compare with the job practices of routine, construction risk is reduced to minimum.
2. technology is easy, has shortened the girders layer construction period
Compare with the cylindrical shell construction of general floor, only need are adjusted the form of the supporting member-lattice column of steel platform and the position of Hoisting System-Lift-slab machine, and need not carry out big transformation to steel plateform system, can realize that steel plateform system integral body successively promoted girders layer.Simultaneously, with the construction of the above level of girders layer be connected very smooth and easy, thereby the large form and the pin hand that can directly utilize steel plateform system to carry have improved mechanization degree greatly, have shortened the duration.
3. effectively reduce construction cost
Use job practices of the present invention, the large form and the sealing pin hand that can directly use steel plateform system to carry, and mechanization degree is higher, compares with conventional method, has saved a large amount of templates, pin hand and labour cost.
