Specific embodiment
Illustrated embodiment is described further technical solution of the present invention with reference to the accompanying drawing.
Inverted triangle tubular truss unit 5 of the present invention includes truss lower boom 4, the truss upper left string pipe 6 being parallel to each other
With truss upper right string pipe 7, by corresponding truss between the truss lower boom 4 and truss upper left string pipe 6 and truss upper right string pipe 7
Diagonal brace 8 connects, and supports 9 connections, 6 He of truss upper left string pipe by truss between the truss upper left string pipe 6 and truss upper right string pipe 7
Truss upper right string pipe 7 and truss support the upper plane of 9 composition inverted triangle tubular truss units 5, as shown in Figure 3.
The lateral assembling method of large span inverted triangle tubular truss of the present invention is to spell multiple inverted triangle tubular truss units 5
It is welded into as monolithic architecture component, referring to Fig. 1, Fig. 3, its job step are as follows:
1, according to the quantity of inverted triangle tubular truss unit 5, corresponding multiple groups assembly is set along assembled direction in erecting bed
Device, each assembly device include multiple (stirrup formula) assembly platforms of forward and backward interval setting (every 3m~7m puts one)
1, all assembly platforms 1 of each group are horizontal with level measurement centering after setting completed, so that the levelness between each assembly platform 1
Error is within 2mm.
2, in each assembly device, pipe of respectively setting up that one placed in the middle and the consistent truss of height winds up on forward and backward assembly platform 1
