Abstract
The utility model relates to a bridge engineering technical field discloses a fast speed adjusting of arch rib wind brace gets ready and puts. This adjusting device, including main arch and wind brace truss, the wind brace truss is including the wind brace chord member, be provided with the reservation steel pipe on the main arch, wind brace chord member tip both sides and top all are provided with adjustment mechanism, adjustment mechanism extends the tip of wind brace chord member, the wind brace chord member passes through the adjustment mechanism overlap joint on reserving the steel pipe. The device when wind brace truss hoist and mount are taken one's place, with wind brace truss overlap joint on reserving the steel pipe, then through the deviation that adjustment mechanism adjustment steel pipe interface exists, guaranteed the quality of wind brace truss installation, reduced the holding time of hoist and mount simultaneously, provide the utilization efficiency and the wind brace truss stability aloft of hoist and mount, reduced the safe risk of aerial operation.
Description
Technical field
This utility model relates to technical field of bridge engineering, especially a kind of quick-adjustsing device of steel tube arch rib wind brace.
Background technology
In the steel pipe arch bridge structure of large span, the lateral rigidity of arch rib is typically small, the displacement strengthened can be produced under wind action, it is possible to the normal operation of bridge structure can be affected, be to ensure that one of laterally stable important measures at the wind brace truss connected between main arch. Therefore how to take effective measures and ensure that faster and better wind brace installation being put in place is an important technology in steel tube arch rib installation process. After generally wind brace truss being utilized hoist cable hoisted in position in conventional construction, aloft having reinforced, its length consuming time, wind brace truss waiting time aloft are long, the potential safety hazard that during as met the vile weathers such as strong wind, existence is bigger.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of high-speed adjustment device that can realize the arch rib wind brace that Fast Installation regulates.
The high-speed adjustment device of arch rib wind brace disclosed in this utility model, including main arch and wind brace truss, described wind brace truss includes wind brace chord member, described main arch is provided with reserved steel pipe, described both sides, wind brace chord member end and top are provided with governor motion, described governor motion extends wind brace chord member end, and described wind brace chord member is overlapped on reserved steel pipe by governor motion.
Preferably, described governor motion includes adjustable plate and chock, described adjustable plate one end is welded in wind brace chord member end, the other end offers adjustment breach and extends wind brace chord member end, described adjustable plate has the one end regulating breach and is overlapped on reserved steel pipe, and described chock is arranged in the adjustment breach between adjustable plate and reserved steel pipe.
Preferably, described adjustment breach is excessively outwards flat side by circular arc from wind brace chord member end.
Preferably, described adjustable plate offers hole for hoist.
The beneficial effects of the utility model are: this device is when wind brace truss hoisted in position, wind brace truss is overlapped on reserved steel pipe, then pass through governor motion and adjust the deviation that steel pipe interface exists, ensure that the quality of wind brace truss installa-tion, decrease the holding time of lifting simultaneously, provide utilization ratio and the high-level stability of wind brace truss of lifting, reduce the security risk of aerial work.
Accompanying drawing explanation
Fig. 1 is top view of the present utility model;
Fig. 2 is the enlarged drawing that Fig. 1 wind brace truss is connected with main arch;
Fig. 3 is A-A sectional view in Fig. 2.
Accompanying drawing labelling: main arch 1, wind brace truss 2, wind brace chord member 21, reserved steel pipe 3, governor motion 4, adjustable plate 41, chock 42, regulate breach 43, hole for hoist 44.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further illustrated.
As shown in Figure 1 and Figure 2, the high-speed adjustment device of arch rib wind brace disclosed in this utility model includes main arch 1 and wind brace truss 2, described wind brace truss 2 includes wind brace chord member 21, described main arch 1 is provided with reserved steel pipe 3, described both sides, wind brace chord member 21 end and top are provided with governor motion 4, described governor motion 4 extends wind brace chord member 21 end, and described wind brace chord member 21 is overlapped on reserved steel pipe 3 by governor motion 4.
During use, first wind brace truss 2 is tentatively lifted and put in place, and make wind brace truss 2 can be overlapped on the reserved steel pipe 3 of main arch 1 by governor motion 4, wind brace truss 2 can be carried out left and right adjusting by the governor motion 4 being positioned at both sides, and wind brace truss 2 can be carried out up-down adjustment by the governor motion 4 being positioned at top, so that wind brace chord member 21 accurately docks with reserved steel pipe 3, then carry out docking welding, complete the installation of wind brace truss 2.
The concrete form of above-mentioned governor motion 4 has multiple choices, such as pass through to arrange screw on the steel plate extending wind brace chord member 21 end to be adjusted, chock 42 adjustment etc. form can also be passed through, as shown in Figures 2 and 3, and it is preferred that, described governor motion 4 includes adjustable plate 41 and chock 42, adjustable plate 41 one end is welded in wind brace chord member 21 end, the other end offers adjustment breach 43 and extends wind brace chord member 21 end, described adjustable plate 41 has the one end regulating breach 43 and is overlapped on reserved steel pipe 3, described chock 42 is arranged in the adjustment breach 43 between adjustable plate 41 and reserved steel pipe 3.
Because reserved steel pipe 3 to dock with wind brace chord member 21, therefore both diameters are similar, so needing to arrange adjustment breach 43 on adjustable plate 41, surplus with reserved adjustment, stretch into adjustment breach 43 thickness by regulating chock 42, so that it may regulate reserved steel pipe 3 will with wind brace chord member 21 relative position, and after adjustment puts in place, standing state can be kept relatively stablely, be more conducive to the welding after regulating. Preferably, described adjustment breach 43 is excessively outwards flat side by circular arc from wind brace chord member 21 end, regulate breach 43 near the inside edge of wind brace chord member 21 and circular arc, to improve weight capacity, prevent fracture, and the position overlapped with reserved steel pipe 3 is flat side, it is ensured that what overlap and adjust stablizes, it is prevented that sliding occur.
Additionally, for ease of the lifting of wind brace truss 2, it is preferred that, described adjustable plate 41 offers hole for hoist 44.
