On the basis of above-described embodiment, in another embodiment of the utility model, such as Figure 17, 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.

It is as follows through finite element analysis computation verification result under a kind of embodiment, as shown in figure 19, as seen from the figure, building Height is 16 layers (total 48m high), and under 8 degree of area's geological processes (seismic force is larger), the cumulative horizontal displacement of building is 18.8mm, every layer of horizontal displacement are about 1.2mm (18.8/16=1.2), story drift be 1/2500 (1.2/3000, 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.

In addition, being 32 layers (total 96m high) in depth of building, in 6 degree of area's geological processes as seen from the figure as shown in figure 20 Under (seismic force is smaller) building accumulative horizontal displacement be 50mm, every layer of horizontal displacement is about 1.6mm (50/32=1.6), layer Between angle of displacement be 1/1875 (1.6/3000, wherein 3000mm is that layer is high), be less than most stringent of 1/ in assembled high-level structure The limit value of 1200 angle of displacements, meets shockproof requirements.

As shown in figure 21, as seen from the figure, vertical displacement of the overhanging part under vertical load and earthquake load is up to 23.5mm, overhanging total distance are 16m, and the deflection limit value of cantilever member is 2*16000/400=80mm, 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.
