Description
Technical field
The invention belongs to building structure and science of bridge building field, more particularly to a kind of plate-girder overall assembled composite beam bridge
PCSC shears coupling arrangement.
Background technology
Steel-concrete combined structure is in the performance of the strength of materials, simple and quick construction, structural behaviour are reliable, recyclable profit
With etc. be respectively provided with obvious 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, the girder steel that top surface is provided with WELDING STUDS is usually first erected at, concrete bridge guidance tape has
Two kinds of construction methods, one kind are that girder steel top surface integrally pours concrete bridge guidance tape 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.There are the problem of be：The weight of A concrete bridge guidance tapes is all born by girder steel, causes steel using amount larger；B cast-in-place concretes
The duration of construction is longer and is not easy to ensure quality；C again applies negative moment area bridge guidance tape after bridge guidance tape is coupled with girder steel pre-
Stress, its 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 shearings coupling arrangement, discloses a kind of steel-concrete
Combining 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
Apply longitudinal prestressing, then the pre-buried Shear transfer steel plate by Prefabricated Concrete bridge road rib of slab side to concrete bridge guidance tape by design requirement
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
The construction of full assembled steel-concrete composite beam bridge, and overcome in conventional steel-concrete composite continuous beam to concrete bridge
Guidance tape applies the problem of prestressed validity is poor.But this method needs pre-buried the Shear transfer steel plate and steel to bridge road rib of slab side
Top surface of the beam forms along a plurality of longitudinal joint of overall length of bridge and carries out live single-sided welding, causes site welding workload very big, welds matter
Amount is difficult to ensure that, and so one-side-filled angle weld anti-fatigue performance is poor, and there are security risk.And in order to which said 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), using in place in continuous prefabricated-pushing tow to the Bridge Pier of first steel girder segment, then concrete
In place, pre-buried the Shear transfer steel plate and steel of Hou Duiqiao roads rib of slab side on continuous prefabricated-pushing tow to the girder steel top surface of bridge road plate segment
Each bar longitudinal joint of top surface of the beam carries out site welding, and overcoming existing packaged type bridges construction needs the huge prefabricated/storage spaces of A；B
Large-scale lifting device and road transport condition；Between C prefabricated components the defects of structural seam disease hidden danger.Although there are a series of excellent
Point, but making and in place construction of the girder steel with concrete bridge guidance tape must successively be carried out, it is impossible to and the same period implements, and adds construction
Cycle；Construction stage there are the unfavorable operating mode that the dead weight of bridge guidance tape is only born by girder steel, makes steel using amount therefore obvious increase；Site welding
It is very big to connect workload, welding quality is difficult to ensure that；Meanwhile in order to realize prefabricated and incremental launching construction, it also invented bridge guidance tape section
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 be improved to existing steel-concrete combined structure and construction method, both sheared and joined with PCSS
The advantages of structure is made easy to fabricated construction, and avoid due to PCSS shearing coupling arrangement site welding work and more sensitive weldering
Fatigue problem is stitched, work efficiency is improved, ensures the safe handling of bridge, and reduces engineering risk, there is significant Technological Economy
Comprehensive benefit.
