Description
Technical field
The invention belongs to building structure and science of bridge building field, in particular to a kind of plate-girder overall assembled composite beam bridge
PCSC shears coupling arrangement.
Background technique
Steel-concrete combined structure is reliable, recyclable sharp in the performance of the strength of materials, simple and quick construction, structural behaviour
With etc. all have apparent excellent, thus increasingly become the development trend of bridge structure；Due to steel construction and concrete
Bridge guidance tape material and characteristic have difference, thus how the simple and efficient simultaneously long-term behaviour that is coupled is reliable therebetween, then is engineering
Boundary is all solved the problems, such as in exploration always.
In existing steel-concrete composite beams bridge, it is usually first erected at the girder steel that top surface is provided with WELDING STUDS, concrete bridge guidance tape has
Two kinds of construction methods integrally pour concrete bridge guidance tape one is girder steel top surface to form steel-concrete composite beams bridge；Another kind is on girder steel top
The concrete bridge guidance tape of precast block is installed in face, and reproduction pours seam concrete to realize that bridge guidance tape to form steel-concrete composite beams with being coupled for girder steel
Bridge.The problem is that: the weight of A concrete bridge guidance tape is all born by girder steel, causes steel using amount larger；B cast-in-place concrete
The duration of construction is longer and is not easy to guarantee quality；C again applies negative moment area bridge guidance tape after bridge guidance tape is coupled with girder steel pre-
Stress, partial prestressing are balanced by girder steel, and it is poor that concrete bridge guidance tape can obtain prestressed validity.
The Chinese patent ZL201310130786.4 of entitled PCSS shearing coupling arrangement, discloses a kind of steel-concrete
Composite structure, it is in place using prefabricated bridge guidance tape in the pre-buried Shear transfer steel plate in Prefabricated Concrete bridge road rib of slab side, is installed on girder steel, and
Longitudinal prestressing is applied to concrete bridge guidance tape by design requirement, then by the pre-buried Shear transfer steel plate of Prefabricated Concrete bridge road rib of slab side
Welded connection is carried out with the longitudinal joint that girder steel top surface is formed and forms steel-concrete composite beam, is realized without cast-in-place connection concrete
Full assembled steel-concrete composite beam bridge construction, and overcome in conventional steel-concrete composite continuous beam to concrete bridge
Guidance tape applies the problem of prestressed validity difference.But this method needs the pre-buried Shear transfer steel plate and steel to bridge road rib of slab side
Top surface of the beam forms the live single-sided welding of a plurality of longitudinal joint progress along overall length of bridge, causes site welding workload very big, welds matter
Amount is difficult to ensure, and so one-side-filled angle weld anti-fatigue performance is poor, and there are security risks.And in order to which above structure is carried out
, there is the segment steel-concrete composite beams bridge that continuously prefabricated-pushing tow is coupled afterwards in place in practice of construction and its method of construction (is invented special
Sharp application number: 2016111547567), and using in place on the continuous prefabricated-pushing tow to Bridge Pier of first steel girder segment, then concrete
In place, the pre-buried Shear transfer steel plate and steel of the road Hou Duiqiao rib of slab side on the continuous prefabricated-pushing tow to girder steel top surface of bridge road plate segment
Each longitudinal joint of top surface of the beam carries out site welding, overcomes existing packaged type bridges construction and needs the huge prefabricated/storage space of A；B
Large-scale lifting device and road transport condition；The defect of structural seam disease hidden danger between C prefabricated component.Although there are a series of excellent
Point, but production and in place construction of the girder steel with concrete bridge guidance tape must successively be carried out, and cannot implement the same period, increase construction
Period；Construction stage, there are bridge guidance tapes to be self-possessed only by the unfavorable operating condition of girder steel receiving, obviously increases steel using amount therefore；Site welding
It is very big to connect workload, welding quality is difficult to ensure；Meanwhile in order to realize prefabricated and incremental launching construction, bridge guidance tape section also invented
Duan Lianxu is quick prefabricated-and pushing tow builds the equipment (number of patent application 201611155859.5) of combined bridge.
Therefore, it is necessary to improve to existing steel-concrete combined structure and construction method, both there is PCSS shearing connection
Structure makes the advantages of convenient for fabricated construction, and avoids shearing the work of coupling arrangement site welding and more sensitive weldering due to PCSS
Fatigue problem is stitched, working efficiency is improved, guarantees the safe handling of bridge, and reduce engineering risk, there is significant Technological Economy
Comprehensive benefit.
