New lover.This kind of house is located at downtown prime location mostly, and the function distribution of villa house is imitated on Size Dwelling Design, and has
" hanging garden ", occupant, which stays indoors, can get close to nature；Plane figure design can also be optimized, possessed as villa a
The inhabitation atmosphere of property secret；Along with the full landscape balcony etc. towards Urban Parks or waters, therefore praised by real estate developers
For " the aerial villa " in city.To a certain extent, it is equivalent to villa house ensemble, extends to aerial, " guide look crowd
Mountain is small " imposing manner to be sometimes villa incomparable.
Villa embodies a kind of natural life style as a kind of high-quality house, more representative of inhabitation culture and
Spirit becomes the best inhabitation selection of people's good life needs, and price is high, remote, mating uneven congruence of living all is general
The logical people are difficult to the major reason received to it.And the soil and construction cost of aerial villa and common high residential building are suitable, enjoy
By villa quality and occupy downtown prime location, be the house of new generation that people go after like a flock of ducks, demand crowd will not
It is only limitted to the elite crowd of booming income again, but ruck and middle class, the scale of construction of the market demand is than present high level
House is bigger, not only contains the demand crowd of existing high residential building, will also include a part of existing villa demand crowd.Therefore
As the high-end house in down town, demand is very wide in central U.S. villa.

Structure feature, and it is equipped with notch 16 and convex block 17 in the splicing side of precast floor slab 3, precast floor slab 3 is overlapped in assembling process mixed
The two is fixedly connected while on solidifying soil truss 1, bottom and 11 phase of concrete frame of vertical web member 14, concrete support 15
Part even can be then accommodated in the notch 16, and precast floor slab 3 delivers load to concrete truss 1.And the utility model
The pure solid concrete of truss weight ratio of use it is light, be conducive to antidetonation, and a large amount of concrete and bar material can be saved, this
The standardization of utility model production mould, modularization, high-efficient, truss can be conducive to the connection between room, form different function
Energy.
On the basis of above-described embodiment, in another embodiment of the utility model, such as Figure 16 and Figure 17, the concrete frame
11 are equipped with stretching muscle 22, and the convex block 17 of the precast floor slab 3 is equipped with jack hole 28, and the stretching muscle 22, which is worn, connects the jack hole
28, grouting material is perfused in the jack hole 28.In this way, above structure is conducive to power between precast floor slab 3 and concrete truss 1
Conduction, while greatly improving field erected efficiency, improve construction speed, can be by precast floor slab 3 and mixed by grouting material
Solidifying soil truss 1 connects globality that is integral, and then increasing structure, connect it is more reliable, can operative constraint precast floor slab 3 end
Portion, it is ensured that this connecting node is destroyed smaller under geological process or even do not destroyed.The grouting material is preferably mortar.
Specifically, as follows through finite element analysis computation verification result under a kind of embodiment, as shown in figure 18, as seen from the figure, this
Building is 16 layers (total 48m high) in height, the accumulative horizontal displacement that (seismic force is smaller) builds under 6 degree of area's geological processes
25.7mm, every layer of horizontal displacement are about 1.6mm (25.7/16=1.6), story drift be 1/1875 (1.6/3000, 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.
It as shown in figure 19, is highly 16 layers (total 48m high), (seismic force is larger) is built tired under 8 degree of area's geological processes
Horizontal displacement 314mm is counted, every layer of horizontal displacement is about 19.6mm (314/16=19.6), story drift 1/153
(19.6/3000, wherein 3000mm is that layer is high), greater than the limit value of 1/550 angle of displacement of minimum requirements in assembled high-level structure,
It is unsatisfactory for shockproof requirements.Therefore the structure is only applicable to that the number of plies is not high, the lesser situation of seismic force.
As shown in figure 20, vertical displacement of the overhanging part under vertical load and earthquake load is up to 27.6mm, overhangs
Total distance is 16m, and the deflection limit value of cantilever member is 2*16000/400=80mm, and vertical maximum displacement is less than deflection limit value, because
This 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.
