D () installs the box-type section rod member that winds up in diagonal web member upper end, at middle chord member part and the installation support bar between box-type section rod member that winds up, form Guan Bi local stability unit III, IV；
E single truss structure planar must be taked bracing reinforcement measure with the outer both direction of plane by () in assembled process；
F () repeats step (a)～(e), until truss assembly being completed.
The further technical scheme of the present invention is, in described step (a), determines the installation site of moulding bed according to truss support stress needs and the rod member erection sequence in assembled process.
The further technical scheme of the present invention is, described step (c) and step (d), and the chord member of truss and diagonal web member are formed the local stability unit of several closings in assembled process.
The further technical scheme of the present invention is, in described step (c) and step (d), adopts steel pipe to be supported reinforcing chord member and web member.
The further technical scheme of the present invention is, the local stability cell configuration of described closing is triangle.
The further technical scheme of the present invention is, described lower edge box-type section rod member, middle chord member part and the box-type section rod member that winds up are parallel to each other.
The further technical scheme of the present invention is that described diagonal web member is parallel to each other.
The further technical scheme of the present invention is that described support bar is parallel to each other.
The further technical scheme of the present invention is, in described step (e), by longitudinally connected beam and diagonal brace, adjacent two truss structures is connected into the local stability unit of closing in the plane.
Beneficial effect
The present invention adopts space to form the assembling method of Guan Bi local stability unit, effectively solve that the fixing difficulty of box-type section in assembled process is big, poor stability and the drawback such as security risk is high, also make to adjust component in assembled process convenient, thus improve component assembly precision simultaneously.

Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is expanded on further.Should be understood that these embodiments are merely to illustrate the present invention rather than restriction the scope of the present invention.In addition, it is to be understood that after having read the content that the present invention lectures, the present invention can be made various changes or modifications by those skilled in the art, and these equivalent form of values fall within the application appended claims limited range equally.
Embodiment 1
Being illustrated in figure 1 the structure chart of superelevation super-span box component truss, this truss installed height mark that winds up is 31.5m, and structural span is about 72m, width about 38m, high 8m, certainly weighs about 1600t.
Concrete assembled step:
1, the location of reasonable arrangement moulding bed 1 and installation, as shown in Figure 2；The position of moulding bed 1 determines the rod member erection sequence mainly needed and in assembled process according to truss support stress.In this example, erection sequence is that width starts from side to install, and length direction is then installed from centre to both sides, and detailed step is such as shown in Fig. 5 to Figure 18；
2, according to component design and fabrication form, assembled lower edge box-type section rod member 2,3 on moulding bed 1, and lower edge box-type section rod member 2,3 is connected firmly, as shown in Figure 2；
