Description
Technical field
The present invention relates to field of bridge construction, in particular to a kind of construction method that steel tube arch rib segment connects in the air.
Background technique
Cable-hoisting construction method is one of CFST Arch Bridge main construction method, and as shown in Fig. 1, it is by arch rib edge
Bridge is divided longitudinally into several rib-lifting sections 01, and by the lifting of tower crane 03 and 04 mode of traction of cable, rib-lifting section 01 is transported
To aerial installation site, then it is soldered in 02 structure of arch rib erection.
In order to guarantee to lift the precision and quality of the aerial welding procedure of rib-lifting section, need its temporary locking to having installed
On rib structure, temporary locking mode and its construction method are to be welded to connect the key link of construction, relationship arch rib steel-tube construction
Stress and safety, have an effect on the perfusion intensity and quality of jack-up construction steel pipe inner concrete.
Existing construction method is generally fixed temporarily tubular arch using 05 formula locking device of inner flange as shown in Fig. 2
Rib segment, the 05 formula locking structure of ring flange of first 01 steel duct of arch rib erection segment, then rib-lifting section 01 is lifted to aerial peace
Rib-lifting section 01 is locked in 02 structure of arch rib erection by ring flange 05 and bolt connecting mode, is then pacified by holding position
Fill the docking casing 07 at joints, and will docking casing 07 with 01 steel pipe of rib-lifting section and 02 steel pipe of arch rib erection respectively
Butt welding is carried out, steel tube arch rib segment 01 is completed and welds in the air.
But the construction method of above-mentioned 05 formula locking device of ring flange has the following problems:
1, the skyborne rib-lifting section 01 of lifting is positioned using the construction method of ring flange 05 and bolt device to hole, because of device to hole
Installation accuracy requirement is very high, and positioning difficulty is big, construction efficiency is low；
2, in locking device installation, 06 both ends of floor are all made of welded connecting, and welding procedure easily leads to ring flange 05
It bends and influences bolt installation, welding residual stress also results in steel tube section stress collection and neutralizes unbalance stress；
3, locking device is set to steel duct, and after docking the embedding benefit of casing 07, locking device can not be removed and be reused, no
Construction auxiliary expenses is increased only, and stops the jack-up construction of steel pipe inner concrete.
Summary of the invention
