Description
Technical field
The present invention relates to a kind of bridge auxiliary construction device, particularly relate to a kind of bridge rotator construction ball pivot.
Background technology
Fast development along with China railways, highway, the bridge of crossing over existing line will get more and more, the design and construction of crossing over the existing line bridge becomes in the Bridges in Our Country engineering by question of common concern, at present span less than 150m with interior bridge design in, reinforced concrete continuous beam is the most frequently used employing scheme.
The continuous girder bridge job practices has 4 kinds at present, the method for namely turning, incremental launching method, free cantilever casting method and support cast-in-place method, and these 4 kinds of method for bridge construction respectively have excellent, shortcoming.For the continuous beam of crossing over existing line, incremental launching method, free cantilever casting method and cast-in-place support method are disturbed greatly railway operation because the interior activity duration of line is long, have bigger construction risk, thereby less being used.And the method cross-line activity duration of turning is short, construction safety risk is less relatively, and is little to existing line operation influence, and therefore, the method for turning is to cross over the more satisfactory method of existing line construction.
The method of continuous girder bridge rotator construction mainly contains 2 kinds, it is the method for turning at the bottom of the pier and the Dun Ding method of turning, the continuous girder bridge rotator construction need use the construction ball pivot, traditional construction ball pivot is fixed on top rotary table in the concrete, after finishing, construction namely seals admittedly by concreting, make the construction ball pivot not reuse by secondary, caused great cost waste.
Summary of the invention
For addressing the above problem, the invention provides a kind of bridge rotator construction ball pivot that is repeatedly used.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of bridge rotator construction ball pivot that can reuse, comprise with the last ball pivot of fixedlying connected at the bottom of the beam and with pier and push up the following ball pivot of fixedlying connected, the upper surface of last ball pivot is fixedly connected with crab-bolt, fixedly connected with last crab-bolt and to be provided with upper bush at the bottom of the built-in beam, the soffit of following ball pivot is fixedly connected with down crab-bolt, fixedlys connected with following crab-bolt to be provided with the lower sleeve that embeds Dun Ding.
Be further used as the improvement of technical solution of the present invention, the upper surface of following ball pivot is the sphere of indent, the soffit of last ball pivot is the sphere of the evagination that is complementary with following ball pivot, and last ball pivot is provided with the centre bore that communicates with the center of following ball pivot, is provided with central pin shaft in the centre bore.
Be further used as the improvement of technical solution of the present invention, the upper surface of last ball pivot is provided with and the pre-embedded steel slab of fixedlying connected at the bottom of the beam, is provided with billet between the bottom surface of pre-embedded steel slab and the upper surface of last ball pivot.
Be further used as the improvement of technical solution of the present invention, be equipped with anchor hole on pre-embedded steel slab and the billet.
Be further used as the improvement of technical solution of the present invention, the periphery of last ball pivot and following ball pivot is equipped with junction plate, is provided with some connecting bolts between two junction plates.
Be further used as the improvement of technical solution of the present invention, be provided with some circular grooves in the spill sphere of following ball pivot, be provided with some slide plates in the circular groove.
Be further used as the improvement of technical solution of the present invention, slide plate is polytetrafluoroethylmaterial material.
Beneficial effect of the present invention: the last ball pivot of this bridge rotator construction ball pivot by last crab-bolt and upper bush with carry out dismountable the connection at the bottom of the beam, ball pivot also passes through crab-bolt and lower sleeve and dismountable connection of pier jacking row down under it, after bridge is finished rotator construction, removable ball pivot and the following ball pivot laid down, repeatedly to be re-used in the bridge rotator construction, save the cost of bridge rotator construction.
