Point,
Step 2, that umbrella footpath steel truss part, collar tie beam steel construction part and the vault of heaven steel truss part are divided into multiple liftings again is single
Unit；
Step 3, on-site consolidation：Respectively by each lifting elements of umbrella footpath steel truss, collar tie beam steel construction and the vault of heaven steel truss on ground
Assembled in place successively according to assembled order；
Step 4, the lifting of umbrella footpath steel truss：Umbrella footpath steel truss each several part segmental hoisting is gone forward side by side to designed elevation using tower crane
Welding short covering between row section and section；
Step 5, temporary support：The lattice temporary support of the vault of heaven steel truss bottom is installed on the basis of the steel truss of umbrella footpath；
Step 6, installing ring joist steel structure：Collar tie beam steel construction part is averagely divided into 4 sections of installations；
Step 7, installation the vault of heaven steel truss：The vault of heaven steel truss is averagely divided into 21 units and is lifted successively, opened from an axis
Begin, lift to both sides successively；
Step 8, short covering welding：After the completion of the girder truss lifting of the vault of heaven steel truss, carry out the rod member short covering between piecemeal and weld
Connect；
Step 9, dismounting temporary support：Entirety when umbrella footpath steel truss part, collar tie beam steel construction part and the vault of heaven steel truss part
All after installation, temporary support is removed.
The installation method of described Ecology umbrella single-layer lattice shell steel construction, before step 4, step 6 and step 7 are implemented
Whole Process Simulation Installation Validation is carried out using finite element analysis software.
This installation method by modular division twice, and further division after module be finely divided again, pre-assembled
The method for lifting respectively and carrying out overall splicing in high-altitude carries out the installation of special-shaped single-layer latticed shell；So as to overcome
The problem that single-layer lattice shell steel structural overhead welding capacity in bulk is big, homework precision is poor and security risk is high, and due to the division of labor in advance
Clearly, single lifting operation difficulty is little causes this construction method that also there is short construction period.

Specific embodiment
The present invention is further illustrated below by way of specific embodiment.
As shown in Figure 1 and Figure 2, it is umbrella footpath 101, collar tie beam 102, the vault of heaven 104 by 1 point of umbrella reticulated shell steel truss and realizes peace
The temporary support 103 of dress, erection sequence is as shown in Figure 2：101 steel truss part of umbrella footpath is installed first, secondly installs interim
The vault of heaven 104 installed by support 103 and collar tie beam 102, last subdivision.
As shown in figure 3, the lifting elements in umbrella footpath 101 divide schematic diagram, which is divided into 4 lifting elements J01 ~ J04, each
Lifting elements are divided into 3 assembled rigid units again；As shown in figure 4, the lifting elements of collar tie beam 102 divide schematic diagram, including 4 sections
Rectangular tube L01 ~ L04 for 900mm × 400mm × 30mm × 30mm；As shown in figure 5, the lifting elements in the vault of heaven 104 are divided illustrating
Figure, including 21 lifting elements in annular distribution, each lifting elements is made up of 3 assembled rigid units again.
Fig. 6 ~ Fig. 7 is the construction procedure schematic diagram of the present invention；As shown in Figure 6 and Figure 7, the lifting construction of the steel roofing
Method is realized by following steps：
Step 401：After the completion of built-in fitting construction, 101 steel truss of umbrella footpath march into the arena after preassembling lifting elements J01, then overall pacify
Dress J01 units；
Step 402：Preassembling lifting elements J02, after the completion of install J02 units, while to covering between J02 and J01；
Step 403：Preassembling lifting elements J03, after the completion of install J03 units, while to covering between J03 and J03；
Step 404：Preassembling lifting elements J04, after the completion of install J04 units, while to covering between J04 and J03；
Step 405：Temporary support 103 is installed, including the crossbeam at the top of lattice column, lattice column；
Step 406：Lifting elements L01 of collar tie beam 102 are installed；
Step 407：Lifting elements L02 of collar tie beam 102 are installed, lifting elements L02 and L01 are covered；
Step 408：Lifting elements L03 of collar tie beam 102 are installed, lifting elements L03 and L02 are covered；
Step 409：Lifting elements L04 of collar tie beam 102 are installed, lifting elements L04 and L03, L04 and L01 are covered；
Step 410：The 104 first piece steel truss lifting elements of the vault of heaven being made up of assembled rigid unit Q7, Q28 and Q49 are installed, after the completion of
Main chord of the closing between Q7, Q28, Q49；
Step 411：Second piece and three piece steel truss of the vault of heaven 104 first piece steel truss both sides, second piece steel truss are lifted respectively
Frame is made up of assembled rigid unit Q8, Q29 and Q50, and the 3rd steel truss is made up of assembled rigid unit Q27, Q48 and Q69；
Step 412：Closing Q8, Q29, Q50 and Q27, the main chord between Q48, Q69, short covering second, the 3rd steel truss with
Web member between first piece steel truss；
