Description
Technical field
The invention belongs to a kind of bridge structure components, more particularly to the assembled hollow steel pipe constraint only pillar height of armored concrete
Pier and its mounting process.
Background technology
Steel tube confinement armored concrete is the fill concrete in thin-wall steel tube, and steel pipe does not directly take on external loads, and
A kind of combined member of effect of contraction is mainly played to core concrete.Steel tube confinement reinforced column high capacity, antidetonation and
Fire resistance is superior, can make full use of the intensity of high-strength steel and concrete.When steel tube confinement reinforced concrete member Covered with Angles
Manage for circle when, steel pipe constrains core concrete uniform, can make full use of the tensile strength of steel pipe, economic benefit is good.With
The development of urban transportation, Urban Bridge is also higher and higher to bridge pier requirement, can save material using hollow section column, simultaneously
The bending resistance and anti-twisting property, the type bridge pier for improving bridge pier are found broad application in Urban Bridge.China just progressively pushes away at present
Wide building industrialization, industrialized building not only have many advantages, such as that speed of application is fast, construction quality is high, construction environment improves, and
Meet sustainable development requirement.The assembled hollow steel pipe constraint only column bridge of armored concrete is proposed according to industrialized building feature
Pier.
The content of the invention
In order in bridge structure promote novel fabricated steel tube confinement reinforced concrete structure, play its mechanical property,
It makes full use of material, improve economic performance, the advantages such as accelerate construction progress, and assembled steel tube is used in higher bridge
This technology of constraint armored concrete, the present invention provides a kind of assembled steel tubes to constrain the only pillar height pier of armored concrete.
For hollow existing the object of the invention the technical solution adopted is that such, a kind of assembled hollow steel pipe constrains reinforcing bar
Concrete pillar height pier, it is characterised in that:Including the pier bottom concrete column being prefabricated in the factory and several concrete short columns and scene
The foundation of construction.
There is the muscle cage of annular inside the pier bottom concrete column.The concrete column outside steel pipe.Among the muscle cage
It is lower end opening, the hollow space of upper end closed.The lower surface of the pier bottom concrete column has special grout sleeve.
Before the special grout sleeve is formed, two rings need to be reserved in concrete column lower surface in precast concrete column
Connected in star.Between the two annular grooves, there are several pipelines to communicate.
The outer surface of the steel pipe has several holes.The outer surface of these holes connection steel pipe and an outer ring
Connected in star.
The foundation is by concreting, internal pre-buried several longitudinal reinforcements and shaped steel shear key.These longitudinal directions
The upper surface of foundation is exposed in the upper end of reinforcing bar, and surrounds two annulus.Also basis is exposed in the upper end of the shaped steel shear key
Partial upper surface, and in the center of two annulus.
At least one grout lines are reserved in the foundation.
When the concrete column is lifted into the foundation top, the lower end of the steel pipe and the foundation
Upper surface contact.There is gap between the upper surface of the concrete column and the foundation.The longitudinal reinforcement
Upper end is stretched into two annular grooves.The upper end of the shaped steel shear key is stretched into hollow space.The grout lines
One end nozzle covered by concrete column, other end nozzle is not covered by concrete column.
Grouting material is poured by the space of the hole and/or grout lines between concrete column and foundation.
The grouting material is filled in two annular grooves, forms special grout sleeve.The special grout sleeve include grout sleeve I,
