Engineering field.
Background technology
The on-site concrete construction of concrete filled steel tube pillar bridge pier typically uses cast-in-place concrete, and wet trade amount is big.To protect
The globality of bridge pier is demonstrate,proved, concrete filled steel tube pillar bridge pier does not use sectional making steel core concrete column and field erected side typically
Method.
Concrete-filled Double Skin Steel Tube Columns are a kind of new shapes that be developed on the basis of traditional steel core concrete column
Cylindricality formula, with axial bearing capacity it is high, shear-carrying capacity is high, energy dissipation capacity is strong, member dead weight is light, easy construction etc. is many excellent
Point.In existing document, there is not yet concrete-filled double skin steel tube lattice bridge pier is applied in bridge structure, therefore,
The present invention combines the prefabricated assembled technology of combining structure, the prefabricated assembled concrete-filled double skin steel tube lattice bridge of proposition
Pier is a kind of new shape bridge pier, can effectively accelerate speed of application, and reduce situ wet operation amount has superior stress performance simultaneously.
Hollow sandwich steel pipe in prefabricated assembled concrete-filled double skin steel tube lattice bridge pier proposed by the present invention is mixed
Solidifying earth pillar and Wavelike steel webplate can be prefabricated in the factory, and the segmentation of the particularly Concrete-filled Double Skin Steel Tube Columns in bridge pier is prefabricated
Bridge pier from the great caused inconvenient problem of transport is solved with installation.Because rectangular steel pipe out of plane constraint is weak, easily occur outside plane
Unstability, concrete-filled circular steel tube column is laid between interlayer steel tube can effectively reduce concrete-filled double skin steel tube forfeiture bearing capacity
Speed, so as to improve the ductility of concrete-filled double skin steel tube；Perfusion high-strength concrete in round steel pipe, it is common mixed outside round steel pipe
Solidifying soil can constrain the deformation of round steel pipe, improve the bearing capacity of concrete-filled circular steel tube column, so as to effectively improve hollow sandwich steel
The axial carrying capacity power of pipe concrete column, and then column cross-section size can be reduced.Presstressed reinforcing steel can effectively suppress hollow sandwich steel
The generation and development in pipe concrete lattice bridge pier crack under geological process.It is traditional to sew for example flat batten plate of material and angle steel is volatile
Surely, Wavelike steel webplate then has Out-of Plane Stiffness higher, and stability bearing capacity is high.Mixed using Wavelike steel webplate connection hollow sandwich steel pipe
Solidifying earth pillar limb can effectively improve concrete-filled double skin steel tube lattice bridge pier overall stability.Prefabricated assembled hollow sandwich
Concrete filled steel tube lattice bridge pier has good ductility and an energy dissipation capacity, and speed of application is fast, the characteristics of situ wet operation is few
The content of the invention
To solve the problems, such as the factorial construction of bridge structure concrete-filled double skin steel tube lattice bridge pier, the present invention is provided
A kind of prefabricated assembled concrete-filled double skin steel tube lattice bridge pier, Concrete-filled Double Skin Steel Tube Columns are using overlapping rod structure
Form, it is possible to achieve the prefabricated assembled construction of concrete-filled double skin steel tube lattice bridge pier.The structure type has antidetonation
High capacity, ductility is good, the characteristics of good integrity, post limb and waveform steel abdomen in concrete-filled double skin steel tube lattice bridge pier
Plate is using factory process making, site-assembled form of construction work, live welding operation, form work engineering and concrete situ wet
Operation is less, and it is convenient to construct, and is conducive to shortening the duration.
The technical scheme is that：
A kind of prefabricated assembled concrete-filled double skin steel tube lattice bridge pier, it is characterised in that：Its bridge pier includes hollow
Interlayer steel tube concrete column, anchor slab, cover plate, presstressed reinforcing steel, anti-shear ring, concrete leveling layer, Wavelike steel webplate, bolt, connection
Plate.There is pre-stressed steel pipe high-strength concrete between inner layer steel pipe and outer layer pipe in the Concrete-filled Double Skin Steel Tube Columns limb of use
Post, during the installation of Concrete-filled Double Skin Steel Tube Columns, before one section of Concrete-filled Double Skin Steel Tube Columns often is installed,
The top surface of concrete leveling mounted Concrete-filled Double Skin Steel Tube Columns need to be used.The cover plate of use is mixed in hollow sandwich steel pipe
The top of solidifying earth pillar limb；The anchor slab of use is embedded in cushion cap；Presstressed reinforcing steel one end is anchored at anchor slab in the presstressed reinforcing steel of use
On, other end tensioning on the cover board strengthens the globality of Concrete-filled Double Skin Steel Tube Columns limb；During the connecting plate of use is welded on
On empty interlayer steel tube concrete column limb；The Wavelike steel webplate of use is connected by bolt with connecting plate.
The present invention has following effective effect：
1. the factorial construction of the concrete-filled double skin steel tube lattice bridge pier in science of bridge building is solved the problems, such as.
2. round steel pipe high-strength concrete column, interlayer steel are had between the interlayer steel tube of the Concrete-filled Double Skin Steel Tube Columns for using
Normal concrete restrained circle pipe deformation between pipe, improves the bearing capacity of post, and column cross-section size can be smaller.Rectangular steel pipe is easily sent out
The outer unstability of dough, the presence of round steel pipe high-strength concrete column can effectively reduce the speed of columns bearing capacity reduction, improve the change of post
Shape and ductile performance.
3. under geological process, column section occurs the trend of tension.The tensile strength of concrete is low, easily cracking.
Tensioned prestressing bar can make column section produce compression, so as to the crack of concrete-filled double skin steel tube lattice bridge pier can be suppressed
Produce and develop.
4. material is sewed as bridge pier using Wavelike steel webplate, compared with common batten plate and angle steel, outside Wavelike steel webplate face just
Degree is big, with stability bearing capacity higher.
5. the Concrete-filled Double Skin Steel Tube Columns and Wavelike steel webplate in concrete-filled double skin steel tube lattice bridge pier are equal
It is prefabricated in the factory, particularly post limb uses factory's sectional making, is conducive to component conveying and in-site installation.
