Abstract
Bridge Rotation Construction Technique Rotary ball hinge, to meet the vertical bearing capacity of bridge construction overall process, realizes freely rotating of Rotary ball hinge top bridge construction.Comprise the upper ball pivot a pair with suitable lower concave spherical surface, lower ball pivot, this is provided with an integral type wear-resistant plate between ball pivot, lower ball pivot, a shear pin passes upper ball pivot, wearing plate and lower ball pivot along the pivot center of Rotary ball hinge.The circular periphery of described upper ball pivot is evenly equipped with the installing hole passed for pre-buried rod iron, lower ball pivot is arranged on embedded bracket by bolt assembly.
Description
Technical field
The utility model relates to bridge construction utensil, particularly a kind of Bridge Rotation Construction Technique Rotary ball hinge.
Background technology
At cross way bridge construction, cross a river paddy bridge construction and under other interfere normal bridge construction condition, all need to adopt Rotary ball hinge to carry out rotator construction to bridge.
Existing Rotary ball hinge includes ball pivot, lower ball pivot, bearing pin, nonmetal slide plate and support framework, upper ball pivot and lower ball pivot are connected as a single entity by bearing pin, lower ball pivot spherical plate concave spherical surface have some grooves that annular is uniform, in each groove, inlay nonmetal slide plate, lower ball pivot is placed on support framework.Its main weak point shows that top anchoring is firm not, and lower spherical hinge structure is complicated, manufactures inconvenience.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of Bridge Rotation Construction Technique Rotary ball hinge, to meet the vertical bearing capacity of bridge construction overall process, realizes freely rotating of Rotary ball hinge top bridge construction.
It is as follows that the utility model solves the technical scheme that its technical problem adopts:
Bridge Rotation Construction Technique Rotary ball hinge of the present utility model, comprise the upper ball pivot a pair with suitable lower concave spherical surface, lower ball pivot, it is characterized in that: be provided with an integral type wear-resistant plate between described upper ball pivot, lower ball pivot, a shear pin passes upper ball pivot, wearing plate and lower ball pivot along the pivot center of Rotary ball hinge; The circular periphery of described upper ball pivot is evenly equipped with the installing hole passed for pre-buried rod iron, lower ball pivot is arranged on embedded bracket by bolt assembly.
The beneficial effects of the utility model are, can meet the vertical bearing capacity of bridge construction overall process, realize freely rotating of Rotary ball hinge top bridge construction; Compact conformation, installation, convenient and quick construction, do not affect traffic; Spherical hinge structure is simple, is convenient to manufacture and install.
Accompanying drawing explanation
This manual comprises following two width accompanying drawings:
Fig. 1 is the structural representation of the utility model Bridge Rotation Construction Technique Rotary ball hinge;
Fig. 2 is the top view of the utility model Bridge Rotation Construction Technique Rotary ball hinge;
Component shown in figure and corresponding mark: upper ball pivot 10, installing hole 11, anchorage bolt 12, pre-buried rod iron 13, lower ball pivot 20, wearing plate 30, annular stop side plate 31, embedded bracket 40, shear pin 50.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
See figures.1.and.2, Bridge Rotation Construction Technique Rotary ball hinge of the present utility model, comprises upper ball pivot 10, the lower ball pivot 20 a pair with suitable lower concave spherical surface.The pivot center of integral type wear-resistant plate 30, shear pin 50 along Rotary ball hinge is provided with through upper ball pivot 10, wearing plate 30 and lower ball pivot 20 between described upper ball pivot 10, lower ball pivot 20.The circular periphery of described upper ball pivot 10 is evenly equipped with the installing hole 11 passed for pre-buried rod iron 13, lower ball pivot 20 is arranged on embedded bracket 40 by bolt assembly.
When bridge construction, Rotary ball hinge and ancillary facility are arranged between beam and pier, bridge according to not intersecting and facilitating position to construct, to be onstructed complete after, utilize draw-gear draw Rotary ball hinge rotate arrive precalculated position, complete construction.On this device, ball pivot 10 is connected with superstructure with anchorage bolt 12 by pre-buried rod iron 13, lower ball pivot 20 is by embedded bracket 40 leveling and connection, realize rotating by wearing plate 30 between upper ball pivot 10, lower ball pivot 20, shear pin 50 ensure that the location in rotation process, and bear horizontal shear, this apparatus structure is compact, and convenient and quick construction does not affect traffic.
With reference to Fig. 1, the annular rim portion of described wearing plate 30 has vertically to the annular stop side plate 31 of downward-extension, and the ring edge of lower ball pivot 20 is positioned at the space that this annular stop side plate 31 limits.
Some principles of the above the utility model Bridge Rotation Construction Technique Rotary ball hinge that just explains through diagrams, be not the utility model to be confined to shown in and in described concrete structure and the scope of application, therefore every corresponding modify of being likely utilized and equivalent, all belong to the scope of the claims that the utility model is applied for.
