Detailed description of the invention
Fig. 1 is construction process figure of the invention.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples:
Embodiment 1
It will be seen from figure 1 that a kind of arc cantilever steel girder construction method for hanging of the present embodiment, comprising the following steps:
Step 1. application BIM technology creates cantilever steel girder three-dimensional visualization model；Girder steel total height 53m, total length 67m,
Fixed section vertical length 43m overhangs end length 24m, radius of the radian R4.7m；
Step 2. using a kind of self-control fixed frame to overhanging end carry out temporary support, this fixed frame be it is detachable, by one
Section segment type steel is assembled；With the preparatory casting concrete base in ground junction, pre-embedded anchoring bolts, it is ensured that firm；Calculate steel
Beam weight and length select crane, wirerope etc.；Single girder steel weight 18t, length 67m, select 150t crawler crane 1
Platform, suspension centre select 2,2, wirerope；
For step 3. using finite element analysis cantilever steel girder, temporary support and hoisting process force analysis, selection is suitable
Suspension centre and temporary support point, and it is quasi- based on BIM technology to carry out dynamic lifting simulation, unloading simulation, temporary support peace demoulding；
Step 4. girder steel is marched into the arena, and temporary support installation, crane is in place, and examination is hung, lifting；The whole liftoff 20cm of girder steel, hangs
Vehicle suspends 5 minutes；In lifting, every raising 5m carries out absolute altitude monitoring；
Step 5 cantilever steel girder is in place, and girder steel and the installation of support tie point are fixed, and overhanging end is fixed on temporary support；
Crane suspention, while overhanging end and being fixed on temporary support, keep girder steel completely in place, the connection for carrying out girder steel and support is pacified
Dress；
Step 6. wirerope gradually unloads, and temporary support is removed.
Schematically the present invention and embodiments thereof are described above, description is not limiting, institute in attached drawing
What is shown is also one of embodiments of the present invention, and actual method is not limited thereto.So if the common skill of this field
Art personnel are enlightened by it, without departing from the spirit of the invention, are not inventively designed and the technical solution
Similar frame mode and embodiment, are within the scope of protection of the invention.
