On the basis of above-described embodiment, in another embodiment of the utility model, it is perfused in the jack hole and recess Slurry.

A kind of calculating verification result under embodiment is as follows, as follows through finite element analysis computation verification result, such as Figure 20 institute Show, as seen from the figure, depth of building is 32 layers (total 96m high), the accumulative level of (seismic force is larger) under 8 degree of area's geological processes Displacement is 74.6mm, and every layer of horizontal displacement is about 2.33mm (74.6/32=2.33), story drift 1/1288 (2.33/3000, wherein 3000mm is that layer is high), less than the limit value of 1/1200 angle of displacement most stringent of in assembled high-level structure, Meet shockproof requirements.Therefore the structure is suitable for the situation that the number of plies is high, seismic force is larger.

As shown in figure 21, depth of building is 32 layers (total 96m high), and under 8 degree of area's geological processes, overhanging part is vertical Vertical displacement under load and earthquake load is up to 62mm, and overhanging total distance is 16m, and the deflection limit value of cantilever member is 2* 16000/400=80mm, vertical maximum displacement is less than deflection limit value, therefore the cantilevered structure can satisfy structure safety and use It is required that.

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and Retouching also should be regarded as the protection scope of the utility model.
