Long axis 111 and short axle 112, the construction method of aluminum alloy latticed shell structure according to the present invention first include from the one of support ring 11
End starts to build the first truss 21 in support ring 11, which is parallel to the extension of short axle 112, and both ends pass through anchor ear
It is fastened in support ring 11.As shown in Fig. 2, along the direction of long axis 111, aluminum alloy latticed shell structure according to the present invention
Construction method continues to build the second truss 22, the third truss 23, the 4th purlin extended each parallel to short axle 112 in support ring 11
Frame 24, the 5th truss 25, the 6th truss 26, the 7th truss 27, the 8th truss 28, the 9th truss 29, the tenth truss 210 and the tenth
One truss 211.In order to reinforce intensity, truss structure further includes the first boom 212 extended each parallel to long axis 111, the second purlin
Bar 213 and third boom 214, wherein the second boom 213 extends along long axis 111 and its both ends is separately connected the first truss 21
With the 11st truss 211, the first boom 212 and third boom 214 are symmetrically located at the two sides of the second boom 213 and its both ends point
It Lian Jie not third truss 23 and the 9th truss 29.It should be understood that the number and location of truss 21-211 and boom 212-214 can be with
It is adjusted as needed.
As shown in figure 3, next the construction method of aluminum alloy latticed shell structure according to the present invention includes on truss structure 2
It is fixedly connected with scaffolding structure 3.Specifically, the height due to aluminum alloy latticed shell structure yet to be built at middle part is higher, in third purlin
The middle part of frame 23, the 4th truss 24, the 5th truss 25, the 6th truss 26, the 7th truss 27, the 8th truss 28 and the 9th truss 29
Scaffolding structure 3 is built upwards, to form job platform.Since the specific structure of the scaffolding structure 3 is applied with existing building
Scaffold involved in work method is identical, and details are not described herein.Since aluminum alloy latticed shell structure yet to be built is closing on built steel
Height near the support ring 11 of structure 1 is lower, therefore does not need in the first truss 21, the second truss 22,210 and of the tenth truss
Scaffolding structure is built on 11st truss 211 upwards, nor is needed in third truss 23, the 4th truss 24, the 5th purlin

43 are fixedly connected on the support, the end of six roots of sensation aluminium alloy rod piece 43 are formed connecting node 432 around setting, by that will connect
The end of each aluminium alloy rod piece 43 at node 432 is connected and fixed the assembly for realizing aluminium alloy rod piece 43, then along long axis 111
Direction, with continuing one section of one end assembled aluminium alloy rod piece 43, until support ring 11 is completely covered, as shown in Figure 6.It should manage
Solution can constantly carry out curvature measurement during assembled aluminium alloy rod piece 43, and pass through support node 431 and connection section
432 adjustment deviation of point, to form the final profile of aluminum alloy latticed shell structure 4 as needed.Aluminium alloy rod piece 43 is spelled using the six roots of sensation
The structure being fitted together, three are enclosed a net hole, and the stability of such triangular structure is good, when triangular structure not
When formation, for the structural stability for guaranteeing aluminium alloy rod piece 43, supported respectively using the truss structure 2 and scaffolding structure 3 of lower section
Aluminium alloy rod piece 43.Known aluminum alloy materials are flexible big, are easily deformed during assembly, the present invention by each node 431,
Corresponding amount of deflection and horizontal departure are controlled on 432, can meet construction requirement by the precision controlling of installation within ± 10mm.
In addition, not limited by narrow space since construction operation platform of the invention is limited only to the inside of support ring 11.
Next the construction method of aluminum alloy latticed shell structure according to the present invention includes removing scaffold from truss structure 2
Then structure 3 includes the dismounting truss structure 2 from built steel construction 1.As shown in fig. 7, removing the 11st truss 211 first, so
Continue to remove along the direction of long axis 111 afterwards, until the first truss 21 is removed, to obtain the fixed company on built steel construction 1
The aluminum alloy latticed shell structure 4 connect, as shown in Figure 8.In the present embodiment, truss structure 2 is steel construction, is connected to by pad
On built steel construction 1, in demolishing process, removed by the way of cutting pad.
Above-described, only presently preferred embodiments of the present invention, the range being not intended to limit the invention, of the invention is upper
Stating embodiment can also make a variety of changes.Made by i.e. all claims applied according to the present invention and description
Simply, equivalent changes and modifications fall within the claims of the invention patent.The not detailed description of the present invention is
Routine techniques content.
