Description
Technical field
The invention belongs to Bridge Designs and technical field of construction, and in particular to a kind of rolling support turn for reducing swivel resistance
Body system and method.
Background technique
In order to preferably meet and comply with the demand for development of China's traffic route complicated and changeable, large quantities of new technologies, new construction,
New process, new material, new facility and new departure occur frequently, and the construction of bridge is made to have obtained unprecedented development.The construction of bridge
It experienced the space layout for complexity of interlocking by now from horizontal layout wide in the past, such as some bridges across railway, cross a river over strait
Beam, and in order not to hinder the passage on its traffic main artery, it is necessary to construction method is improved and is innovated.In this case, general
Logical construction method is constructed above the more traffic lines of vehicle can have very big security risk, influence traffic and pass through, cause
Urban congestion, rotator construction come into being under this predicament.
Insure leg in conventional rotation swivel construction method generally drawing within turntable, support radius is relatively small.For oblique pull
Bridge list flexural pivot Horizontal Swing Construction, since bridge tower is tall and slender structure, when encountering wind-force or other larger unbalanced moments act on,
Rotator construction stability is poor, and there are the risks that large eccentricity topples.If considering to move on to other than traction turntable outside insurance leg, expand
It supports radius, is turned using multi-point support, then can greatly increase the stability of rotator construction, reduces the construction that large eccentricity topples
Risk.
For dissymmetrical structure beam bridge Horizontal Swing Construction, need to carry out balance of the counterweight to guarantee swivel structure.If
Consider to move on to outside partial insurance leg other than traction turntable, is turned using multi-point support, then can reduce swivel counterweight, while can
Increase the stability of swivel structure.
However, when tall and slender structure (cable-stayed bridge) or dissymmetrical structure bridge Horizontal Swing Construction, to increase swivel structure
Stability reduces beam body swivel counterweight and takes the measure for moving insurance leg outside, causes to insure the contact resistance at leg
Corresponding multiple will be amplified by being reflected in the tractive force at turntable, and swivel tractive force is larger, and rotation is difficult, even generates and is difficult to rotate
Phenomenon.
