Description
Technical field
The invention belongs to technical field of bridge engineering, and in particular to a kind of energy-dissipating and shock-absorbing node of assembled bridge pier.
Background technique
Currently, Bridges in Our Country substructure mainly uses cast in situs construction method.Often construction is all for cast in situs construction
Phase is long, and labo r usage is big, and construction quality is not easy to guarantee, and has larger impact to surrounding enviroment.To overcome these adverse effects, fill
It comes into being with formula bridge pier form.Compared with the cast-in-place bridge pier of tradition, assembled bridge pier have short construction period, environment influence it is small,
The advantages such as construction quality height meet the industrialized demand for development of China's building structure.As urban modernization and economic high speed are sent out
Exhibition, urban construction are also required to the step immediately following the epoch.When the cast-in-place Bridge Pier Construction of bridge construction often to surrounding enviroment generate compared with
Big adverse effect, the environmental pollution including generating noise and dust etc., the low-carbon advocated with city, environmental protection development are not inconsistent.Therefore,
In the development of the following bridge construction, packaged type bridges will increasingly be taken seriously.
For general assembled bridge pier, whole bridge pier segments all use prefabrication, and it is existing then to transport construction
Carry out assembled, it is weaker that this whole segments are all that the structural system of splicing relative to cast-in-place bridge pier embodies hysteretic energy ability
Characteristic, anti-seismic performance is relatively weak, is mainly used in assembled bridge pier at this stage and non-provides fortification against earthquakes area or low antidetonation is set
The bridge structure in defence area, it would be highly desirable to develop a kind of good node of damping energy consumption effect.

Position is the position that bridge pier is placed, and the shape of the bent cap notch is truncated cone-shaped, and the circular diameter close to bottom end is greater than close to upper end
Diameter of a circle, in the outside of bent cap notch, level is opened up there are four extendable room, the arrangement of the extendable room with it is coplanar
Interior horizontal line and vertical line is all disposed with a high strong spring in the inside of each extendable room at degree angle, described each
A high strong spring all connects a fixture block, and the fixture block is a wedge block, and the wedge-shaped inclination angle of the fixture block end is that degree is extremely spent,
In the outside of bent cap notch, be disposed with four pairs of pre-buried set squares of bent cap, there are hole among the pre-buried set square of bent cap, stay with
Carried out with viscid fluid damper hinged, the innermost end of the bent cap notch is provided with rubber pad, the shape of the rubber pad with
The circle size of the innermost end of bent cap notch is identical；
The material of the bridge pier is concrete, and the shape of the pile body of bridge pier is cylinder, in pile body close to the position on top, setting
There is pile body to expand disk, the shape that the pile body expands disk is also circle, expands on disk in pile body, is provided with four pairs of bridge piers pre-buried three
Gusset is stayed there are hole among the pre-buried set square of bridge pier to carry out hinged, the top of the pile body with viscid fluid damper
End is provided with pile cover, and the pile cover is truncated cone-shaped, and size is identical as the size of bent cap notch.
Further, the pile body, which expands, is arranged reinforcing bar in disk.
Further, the line of the pre-buried set square of the bent cap and the pre-buried set square of bridge pier and horizontal angle are 30 degree
To 45 degree.
Further, pass through welded connecting between the high strong spring and fixture block.
Further, installation method are as follows: first bridge pier is installed and fixed, bent cap is lifted by crane, aligns and decline, declines process
Effects of Viscous Fluid Damper both ends are respectively hinged at bent cap pre-buried three after it falls surely by the flexible situation of middle observation fixture block, adjustment
On gusset and the pre-buried set square of bridge pier, installation is completed.
Beneficial effects of the present invention
Effect and advantage of the invention is that bearing capacity is higher, construct it is more convenient, be conducive to shorten the construction period, can effectively solve with
Toward method installation contraposition it is inaccurate caused by collide with the problems such as, when earthquake occurs can maximum damping, ensure the logical of bridge
Row ability.
