Description
Technical field
A kind of prestress anchorage system is the utility model is related to, particularly a kind of interchangeable anchorage prestress anchoraging device.
Background technology
Large-scale suspension bridge anchorage anchor system uses prestress anchorage system more, existing conventional pre- in tunnel-type anchorage
Stress anchoring system has two kinds of patterns, and a kind of is the bonded anchoring system for being irrigated in prestressed pore passage slurry, one kind be
The soap-free emulsion polymeization single replaceable anchoring system of perfusion anti-corrosion grease in prestressed pore passage.Large tunnel formula anchorage concrete body length is general
Longer, each beam prestressed pore passage in above two pattern anchoring system is typically provided bending section, is changed by bending section each pre-
The direction of stress beam, to reach the diverging size for reducing each prestressing beam in anchorage concrete body, so as to reduce the chi of whole anchor concrete body
It is very little, carry out reducing construction volume and reduce cost.
In prestressed pore passage irrigate slurry bonded anchoring system, its major defect be antiseptic property it is relatively low,
It is non-exchange, can not monitor.
The soap-free emulsion polymeization single replaceable anchoring system of anti-corrosion grease is irrigated in prestressed pore passage, such as patent of invention " suspension cable
The prestressed method and device of bridge anchoring changeable formula "（The patent No. 200810046645.3）With utility model patent " suspension bridge
The prestressed device of anchoring changeable formula "（Patent No. 200820065240.X）Disclose a kind of in having bending prestressed pore passage
Using honeycomb fashion sub-wire pipe as built-in pipe, the anchoring system of perfusion anti-corrosion grease in built-in pipe；Honeycomb fashion sub-wire pipe solves
Steel strand wires mutually extrude problem when easily playing the problem of twisting and tensioning when steel stranded wire penetrating adapter is constructed in having bending duct.But pass through
Engineering practice in recent years, which is summarized, to be found, the viscous interchangeable anchoring system of nothing of above-mentioned filling oil there is also some can not be ignored
The defects of.Major defect shows：Construction process requirement is high, changing number, more, anchoring property is influenceed greatly by environment and personnel
Deng.
1st, the grease of perfusion is liquid state in prestressed pore passage, it is therefore an objective to which convenient perfusion is changed with later grease；But
Consequently, it is possible to the sealing of system proposes very high request, slightly constructing operation or not in place, the oil in system of inspection to construction
Seepage will occur for fat, and this not only influences outward appearance, it is often more important that the seepage having is difficult to radical cure processing, increases operation maintenance cost
With；Built in early days applies the suspension bridge for filling oily replaceable anchorage system, inadequate because recognizing its sealing, is designing
It is not careful in upper, construction technology to cause anchoring system different degrees of grease seepage to be all present.Especially for there is crooked pipeline
The system of honeycomb fashion sub-wire pipe is employed, because more than various pipe fitting connecting portions and connection is difficult, it is easier to grease seepage occur and show
As.
2nd, because guiding principle twisted wire mainly by grease carrys out anti-corrosion, and the barrier propterty for currently commonly using grease is usually 20-30, big
The life cycle management domestic demand of bridge carries out multiple replacing.
3rd, it is all clip type anchoring to fill oil without viscous interchangeable anchoring system, and the anchoring property of intermediate plate is most important, in advance should
The construction quality of power anchorage is influenceed big by site environment, operating personnel.
To solve the above problems, the applicant has applied patent publication No. for CN104372738A, entitled in succession
《Rope construction method is changed in a kind of single replaceable anchorage prestress anchoraging device and its installation》, patent publication No. is
It is CN104947589A, entitled《Multiply finished product chain-formed anchor prestress anchoraging device and its construction method》Two inventions are special
Profit application, but also have the following disadvantages：Its pre-buried tube portion is all straight built-in pipe, is not suitable for having bending section built-in pipe
Situation.And existing large tunnel formula anchorage concrete body length is general longer, each beam prestressed pore passage is typically provided bending section, by curved
Tune changes the direction of each prestressing tendon, whole so as to reduce to reach the diverging size for reducing each prestressing beam in anchorage concrete body
The size of individual anchor concrete body, carry out reducing construction volume and reduce cost；And patent publication No. be respectively CN104372738A,
In CN104947589A two parts of patents of invention, pre-buried tube portion is straight built-in pipe, it is impossible to changes the direction of each prestressing tendon, no
It is applicable.
The content of the invention
The purpose of this utility model is to provide a kind of interchangeable anchorage prestress anchoraging device, and the interchangeable anchorage in advance should
Power anchor can effectively overcome the defects of Techniques of Tunnel-Type Anchorage for Suspension Bridge conventional prestress anchoraging device；The anchor uses
Honeycomb fashion sub-wire pipe is per share using small dimension multiply finished product rope as presstressed reinforcing steel as the prestressed forming tunnel of bending section
Finished product rope is each passed through each sub-wire pipe.Anchor anchoring is reliable, anti-corrosion is superior, and construction is easy with monitoring, prestress hole
Road does not irrigate anti-corrosion material, and the replacing of multiply finished product rope can be conveniently realized in the case where not influenceing bridge operation, especially
Suitable for there is the tunnel-type anchorage anchor system in bending duct；To solve above mentioned problem existing for prior art.
The technical scheme to solve the above problems is：A kind of interchangeable anchorage prestress anchoraging device, including prestressed concrete
Soil anchoring part and the main cable strand connecting portion for being connected with main cable strand, described main cable strand connecting portion include drawing
Bar, protective cover, front support plate, rear support plate, connector and nut assembly；The prestressed concrete anchoring part includes pre-buried
Fastener inserts in concrete, anchoring strand, the fastener inserts include upper end anchor plate, lower end anchor plate, spiral bar and
Built-in pipe, the anchoring strand are the manufactured finished product ropes in factory, and the built-in pipe of fastener inserts is interior without anti-corrosion material；
It is characterized in that：The built-in pipe includes a sub-wire steering-type built-in pipe and one section of straight built-in pipe, the sub-wire
Steering-type built-in pipe by connecting tube, plectane, n roots bending steel pipe assembly welding form, wherein steel pipe by straightway L1, bending section L2,
Straightway L3 is formed；Sub-wire steering-type built-in pipe by the connecting tube at both ends, plectane respectively with upper end anchor plate and straight built-in pipe
Connection；N is the integer less than or equal to 100 more than or equal to 2.
A kind of further technical scheme of described interchangeable anchorage prestress anchoraging device is：Described front support plate,
The middle part of rear support plate is provided with the n through holes for being used to wear finished product rope.
The anchoring strand of the interchangeable anchorage prestress anchoraging device has n stock finished product ropes, effective lotus of n-1 stock finished product ropes
The design load more than anchored main cable strand is carried, per share finished product rope is more steel strand wires for being surrounded by single or multiple lift sheath outside
Shu Chengpin ropes or more steel tendon finished product ropes or other presstressed reinforcing steel finished product ropes.
