Description
Technical field
The invention belongs to bridge structure technical fields, are drawn more particularly, to a kind of multi-functional anchor tube type anchor of cable-stayed bridge main-beam
Plate.
Background technology
Cable-stayed bridge is one of main bridge type of Large Span Bridges, is widely used in the Important Projects such as over strait, river, river.Oblique pull
Bridge includes mainly Sarasota, girder, suspension cable etc., and girder anchor cable device is key structure therein.
Broad form one of of the anchor tie plate as cable-stayed bridge main-beam anchor cable device, structure is clear with mode of transfer force, can be
Drag-line is easily installed and safeguarded to bridge floor, the advantages that girder construction and small landscape impact, therefore often steel girder, combination steel master
The first choice of beam anchor cable.
Anchor tie plate is applied to concrete girder, at present also in the technology exploration stage.In this regard, foreign countries have not been reported, state
The inside also rarely report of anchor tie plate.
Chinese patent CN104452588A discloses a kind of bridge steel girder and cuts pressure bearing-type anchor tie plate structure.It includes anchor
Pulling plate, the anchor tie plate top are provided with the wide notch in the narrow lower end in upper end, and the notch top embeds anchor trombone slide, anchor trombone slide top
The upper plate washer of portion's welding, bottom weld anchor plate, are equipped with upper bush above the upper plate washer, upper bush and anchor trombone slide are coaxial, described
Anchor tie plate includes two pieces of upper anchor tie plates and one piece of lower anchor tie plate, and the anchor trombone slide lower external face is welded with bearing plate, described to hold
Pressing plate is spaced apart with anchor plate and is mutually parallel.Anchor tie plate structure is mainly used for that anchor structure is overcome to answer in above-mentioned patent
Power concentration, local deformation, fatigue crack problem, it is ensured that the stress safety and service life of structure.Above-mentioned anchor tie plate structure is more
Complexity is unfavorable for the maintenance or replacement of structure member.
Invention content
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of cable-stayed bridge main-beams to use
Multi-functional anchor tube type anchor tie plate.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of multi-functional anchor tube type anchor tie plate is mounted in beam body when use, by the anchor rope component on top, the anchoring of lower part
Anchor rope component is connect by component and connection pulling plate composition, the connection pulling plate with anchoring assembly, forms double-tube series structure, will
Anchor cable power is finally transmitted to concrete beam body by anchor rope component, connection pulling plate, anchoring assembly.
The anchor rope component is made of support tube, anchor plate, top cap plate and conduit, and the anchor plate is welded on support
The bottom of pipe, the top cap plate are welded on the top of support tube, and the conduit is welded on top cap plate；
The anchoring assembly is made of anchor tube, shear connector and backing board, and the shear connector is welded on anchor tube, described
Backing board be welded on the bottom end of anchor tube；
The connection pulling plate upper and lower part is welded in the lateral surface of support tube and anchor tube respectively, forms double-tube series structure.
The connection pulling plate is cross steel plate weldment.
There are two the connection pulling plate is set altogether, the axial direction along support tube and anchor tube is welded on support tube and anchor tube respectively
Both sides.
The sealing wire of the connection pulling plate and support tube or anchor tube is symmetrical with the axis of support tube or anchor tube, and with support
The axis of pipe or anchor tube is coplanar, and the support tube and anchor tube coaxial line, the anchor plate are separately arranged with anchor tube.
The shear connector is equipped with 4 layers altogether.
In use, in the anchor tube Transducers Embedded in Concrete beam body, and shear connector is also in Transducers Embedded in Concrete beam body, the bottom
Supporting plate is welded on the anchor tube bottom for exposing concrete beam body, and backing board is parallel with the bottom of beam body, is partially submerged into beam body, anchor tube,
Shear connector forms multilayer with backing board and cuts pressure power transmission barrel structure.
That is, anchoring assembly of the present invention, based on anchor tube, what is be arranged on the anchor tube of Transducers Embedded in Concrete beam body cuts along Cheng Chuanli
Power key, and expose the end pressure-bearing backing board of the anchor tube bottom setting of concrete beam body, multilayer is collectively formed and cuts pressure power transmission cylinder
Structure.
In use, drag-line passes through conduit, top cap plate, support tube, the anchor plate of support bottom of the tube is anchored at end anchorage
On, drag-line generates pressure on anchor plate, the pulling force being then converted on connection pulling plate, and then is converted into the shearing on anchor tube, most
It is separated into the pressure for contacting concrete on shear connector and backing board to beam body eventually.
When carrying out multi-functional anchor tube type anchor tie plate and safeguarding, it can safely implement off-load.At this point, drag-line is set on end anchorage
Connector extends, and anchor tube is passed through, until backing board, is anchored at interim anchorage on the correcting wedge added.At this point, anchoring assembly is made
Interim anchor cable structure when being safeguarded for anchor rope component etc., anchor cable pulling force can direct part or all transfer be anchor tube bottom pressure.
It fails when such as anchor rope component, connection pulling plate use, can easily convert anchor cable.Prolong at this point, drag-line replaces cable body
It is long, anchor tube is passed through, until backing board, is anchored at end anchorage on the correcting wedge added.At this point, anchoring assembly is as anchor cable group
Replacement anchor cable structure after the failures such as part.Drag-line is replaced cable body and is extended, and anchor tube is passed through, until backing board anchors, directly forms anchor cable
Pressure.Anchor tie plate has the function of dual anchor cable.
Compared with prior art, the present invention has the following advantages and beneficial effects：
1, a kind of completely new cable-stayed bridge concrete girder anchor cable device of the invention.The tensioning and maintenance of drag-line can be
It is completed on bridge floor.It is reachable, detectable, can repair, replaceable condition it is more preferable.
2, structure of the invention mode of transfer force is clear, reliable.Anchor cable power by anchor rope component, connection pulling plate, anchoring assembly most
It transmits eventually and is dispersed to concrete beam body；The backing board of shear connector and the setting of anchor tube bottom that anchor tube is arranged along journey forms multilayer and cuts pressure
Power transmission barrel structure.
When interim anchor cable structure when 3, anchoring assembly of the present invention is safeguarded as anchor rope component etc., anchor cable power direct part or
All transfer is anchor tube bottom pressure.Maintenance process top off-load, the safety is improved.
4, when anchoring assembly of the present invention is as replacement anchor cable structure after the failures such as anchor rope component, anchor cable is directly in backing board
Upper formation pressure.Anchor tie plate has the function of that dual anchor cable, applicability are wider with this.
