Description
Technical field
The present invention relates to a kind of bridge pad more particularly to a kind of layer component each under the action of no-load can be in close contact
Active bearing.
Background technology
The girder of bridge is long, and the factors such as creep and shrinkage of concrete, difference variation and earthquake can cause the longitudinal direction of bridge
Big displacement the technical issues of in order to effectively solve the processing of bridge length travel, employs in domestic and international Partial Bridges design
The form of point connection setting hinged structures (i.e. connection hinge), (P12-P37 refers to pier stud) as shown in Figure 1 on girder.Connection hinge not only will
Meet the bearing capacity requirement under normal operation, also to have the longitudinally opposed displacement of release span centre both sides girder, constrain girder
Vertical, the laterally opposed deformation at both ends and the ability of relative rotation.
Use the science of bridge building that connection is cut with scissors mainly big with the Antioch of California, USA (Antioch) both at home and abroad
Bridge, guest's Nicaea (Benicia-Martinez) bridge, SF Bay (San Francisco-Oakland Bay) bridge,
Country of Ecuador combines bridge for representative, the only 4 rope face cable-stayed bridge steel case girder knot of column of good 6 tower of Main Bridge Channel Bridge that continues in China
Connection hinge is also used in structure.
As shown in Figures 2 and 3.Connection hinge can discharge expansion joint both sides girder due to concrete shrinkage and creep, the system temperature difference
And the longitudinally opposed displacement that earthquake generates.Connection hinge is mainly summarized as single cut with scissors by manner and rolls over chain, two kinds of sleeve strong rod type
Type.
Sleeve strong rod type structure diagram as shown in figure 3, connection hinge position strong rod has vertical constraints more than 2 points, because
This has the ability of constraint rotation in surface, is mainly used in the span centre position of the symmetrical cable-stayed bridge of cantilever and prestressed girder bridge, phase
It closes document and is also referred to as span centre hinge.
As shown in figure 4, connection hinge is influenced by the shrinkage and creep of bridge concrete during later stage operation, mid-span deflection is not
Disconnected to increase, span centre is coupled hinge and is mainly run with the stress of sagging moment.It is horizontal when being coupled stress of the hinge in sagging moment
Partition board B positions steel box-girder upper end bearing 31 and diaphragm plate C positions steel box-girder lower end bearing 34 are influenced each layer member in tight by load
Contact, bearing energy normal operation, and diaphragm plate B positions steel box-girder lower end bearing 32 and diaphragm plate C positions steel box-girder upper end bearing
33 possible influenced by deflection, each layer component cannot be in close contact, and bearing, which is not normally functioning, even generates destruction.
