Description
Technical field
The present invention relates to the bridge plate bridge pier connection methods of building engineering field more particularly to a kind of prefabricated bridge.
Background technique
Bridge construction highway, high-speed railway and overhead road of city construction in be accent, in bridge construction, bridge plate into
There are two types of the modes of row construction: one kind is prefabricated construction, and another kind is cast in situs construction.Prefabricated construction, just
It is that bridge plate is resolved into cell cube to make in factory or precasting yard, then transports to the cell cube for constituting bridge plate at bridge place simultaneously
It is mounted on bridge pier.The advantages of this kind of method for bridge construction, is: bridge pier and bridge plate can parallel construction, the duration is relatively short；Bridge
(boat) current under bridge is influenced in process of construction small.It is existing when being attached to prefabricated bridge plate and bridge pier for by concrete into
Row pours together, and there are the deficiencies of junction Lateral resisting ability difference for which, have then been changed to pass through company in order to overcome the problems referred above
Joint chair is supported between bridge plate and bridge pier, and attachment base is linked together by bolt with bridge plate and bridge pier, although the connection type
Overcome the deficiency of anti-lateral displacement effect difference present in concrete binding mode, but there are bolt it is exposed be easy corrosion outside and
It damages short so as to cause service life.All there is the deficiency of vibration isolating effect difference in any way.
Summary of the invention
The present invention provides a kind of bridge plate bridge pier connection methods of prefabricated bridge that anti-lateral displacement vibration isolating effect is good, solve existing
Prefabricated assembled bridge plate and bridge pier between vibration isolating effect difference problem.
The above technical problem solves by the following technical programs: a kind of bridge plate bridge pier connection method of prefabricated bridge,
