Description
Technical field
The utility model belongs to the technical field of Single column pier bridge anti-overturning devices, specifically, is related to a kind of based on knot
The Single column pier bridge anti-overturning devices of structure self-balancing.
Background technology
In Urban Road-Highway Bridges and bridge on highway process of construction, due to by landform, atural object, floor space and city
City's landscape etc. influences, and its underpart pier stud often just uses Single column pier elastic supports mode, to reduce land occupation, improve substructure cloth
Office, reduce bridge foundation and conflict with hypogee position, increase the visual field and bridge type is attractive in appearance.But, Single column pier bridge is because turned round
Square effect is larger, and lateral stability problem is more prominent.With the continuous increase of the volume of traffic, overload of vehicle, which transfinites, can cause abutment pier side
Seat empty, direction across bridge deformation increase, until bridge topples, the bridge of this kind of structure type has occurred a lot of in use
Capsizing case caused by toppling or overloading in work progress.
Existing Single column pier overturn-preventing, which is reinforced, to be mainly using the lateral stability for strengthening bridge structure as dominant ideas, mainly
Measure has：If the 1, space under bridge allows, column can be set up by former pier stud, this method is required to the underground space, and is needed
Cast-in-place concrete, the engineering time is long.The 2nd, horizontal widened structure is set on pier stud, such as then bent cap, steel hoop etc. are set up
Bearing, strengthens the lateral stability of Single column pier bridge.This method needs to set up bearing, and to carry out jacking to girder.
Utility model content
For deficiency above-mentioned in the prior art, the utility model provides a kind of Single column pier bridge based on structure self-balancing
Anti-overturning devices, the present apparatus by the way that the offset loading force that bridge lateral one end is subject to is delivered into the other end so that structure integrally by
Power is balanced, reduces or offset the displacement that bridge is produced by offset loading force.
In order to achieve the above object, the solution of the utility model use is：A kind of only post based on structure self-balancing
Pier bridge anti-overturning devices, including only post bridge pier and bridge, bridge include left side beam body and right side beam body, left side beam body lower surface
Provided with fixed beam, fixed beam upper end is fixedly connected with left side beam body lower surface, and transmission rod is hingedly connected with only post bridge pier
Part, right side beam body lower surface is fixedly connected with hanger, and the ground of right side down either side, which is fixedly connected with fixed pulley, fixed pulley, to be set
There is strength steel wire rope, strength steel wire rope one end is fixedly connected with one end of power transmission rod member, the other end and fix bar of power transmission rod member
The lower end of part is articulated and connected, and the other end of strength steel wire rope is fixedly connected with hanger.
Preferably, fixed beam is distributed vertically.
Preferably, power transmission rod member horizontal distribution.
Preferably, fixed pulley is distributed between power transmission rod member and hanger.
The beneficial effects of the utility model are that the present apparatus utilizes the Force transmission partses such as power transmission rod member, pulley, strength steel wire rope,
Transmission, conversion, change power direction, by script act on one side offset loading force be delivered to other side so that bridge both sides by
Power is balanced, so as to reach the effect of antidumping；The utility model simple structure, easy construction, using rod member, pulley, moveable hinge
Deng component it is easy to disassemble and change, good antidumping effect can be reached.
Brief description of the drawings
