On the basis of above-described embodiment, in another embodiment of the utility model, such as Figure 23, first built-in fitting 12 and Two built-in fittings 13 include at least connecting plate, and the connecting plate is equipped with threaded connection hole, first built-in fitting 12 and second Built-in fitting 13 is connected by bolt 21.In this way, assembly and disassembly is easy, and connect reliable.

A kind of calculating verification result under embodiment is as follows, as follows through finite element analysis computation verification result, such as Figure 24 institute Show, as seen from the figure, depth of building is 16 layers (total 48m high), and (seismic force is smaller) adds up horizontal position under 6 degree of area's geological processes Moving is 18.8mm, and every layer of horizontal displacement is about 1.175mm (18.8/16=1.175), and story drift is 1/2553 (1.175/ 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 anti- Shake requires.

As shown in figure 25, vertical displacement of the overhanging part under vertical load and earthquake load is up to 49.5mm, overhangs Total distance is 24m, and the deflection limit value of cantilever member is 2*24000/400=120mm, and vertical maximum displacement is less than deflection limit value, Therefore the cantilevered structure can satisfy structure safety and requirement.

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.
