Description
Technical field
The present invention relates to a kind of precast assembly pier stud constructions and construction method that bellows connection is inserted by reinforcing bar, are related to
Field of civil engineering.
Background technique
With protection environment, universal, up-to-dateness requirement of the people for Urban Bridge Construction of energy saving consciousness
It is higher and higher, design, construction personnel from city dweller to bridge, to the construction of Urban Bridge exist fast and safely, energy conservation
Environmentally friendly, small to Coherent traffic noise, construction quality is excellent etc. to be required.Building assembled building technology is the pass for meeting the demand
Key, and the precast assembly technology of bridge superstructure is quite mature, sight is just gradually transferred to by construction with researcher
In the realization of the substructures precast assembly technology such as Bridge Pier, to realize that bridge is entirely prefabricated.
1971, Texas, USA was firstly introduced section assembling bridge pier, crossed over JFK for the city Corpus Christi
The construction of causeway highway bridge, with the introducing of Precast Concrete Segmental Bridges technology, section assembling bridge pier starts in the big rule in the U.S. or Europe
Mould application.For Precast Concrete Segmental Bridges construction technology, China is mainly used in the Superstructure Construction of bridge, section assembling coagulation
The engineer application of native bridge pier is less, and mainly using wet seam connection section assembling solid pier, only Donghai Bridge,
It is applied in the bridges such as Hangzhou Gulf Great Bridge, Beijing ponding pool bridge experimental project, Changjiang River Bridge Shanghai.
There are still many deficiencies, such as bridge pier to be spliced using cast-in-place seam for the connection type of existing assembled bridge pier, bridge pier master
Reinforcing bar Joining Technology is complicated, and quality of connection is not easy to guarantee；Such as using precast assembly structure frequently with grout sleeve connect, by
Small in the construction tolerance of muff joint, more demanding to construction precision, two reinforcing bars docked in sleeve are easy to make mistakes because of construction
Cause one it is too long, one is too short, and there are the risk that anchorage length not enough causes reinforcing bar to be extracted, the at present party for that too short root
Method is not suitable for the connection of antidetonation area fabricated construction.The safety of bridge substructure is particularly important, it is therefore necessary to send out
Bright one kind novel bridge pier seam interconnection technique overcomes disadvantages mentioned above.
Summary of the invention
In view of the deficiencies in the prior art, technical problem to be solved by the invention is to provide one kind to be inserted into ripple by reinforcing bar
The precast assembly pier stud construction and construction method of pipe connection, are not only simple in structure, and convenient and efficient.
In order to solve the above-mentioned technical problem, the technical scheme is that a kind of be inserted into bellows connection by reinforcing bar
Precast assembly pier stud construction, including cushion cap, cushion cap upper surface are equipped with groove, and inside grooves are equipped with the branch to support pier stud bottom surface
Dagger, inside grooves are embedded with several bellowss, several main reinforcements and bellows of pier stud bottom in support column surrounding vertically
It corresponds and is inserted into bellows, bellows interior is equipped with interior filled layer, and inside grooves have poured Concrete Filled layer.
Preferably, vertical main reinforcement and lateral stirrup are disposed with inside the pier stud, main reinforcement is along pier stud short transverse
Extend pier stud bottom surface.
Preferably, the length that main ribs are stretched out outside pier stud bottom surface needs to meet the anchorage length of main reinforcement insertion bellows,
Bellows Length is greater than the anchorage length of pier stud main reinforcement.
Preferably, the Concrete Filled layer uses expansive concrete or ultra-high performance concrete.
Preferably, the bottom of the bellows is embedded in groove slot bottom position below, and the top of the bellows is equal
Positioned at groove slot bottom or more than position but be not higher than groove notch.
Preferably, the interior filled layer uses high-strength mortar or grouting material.
Preferably, the support column top surface is flushed with cushion cap upper surface.
It is a kind of by reinforcing bar be inserted into bellows connection precast assembly pier stud construction construction method, according to the following steps into
Row: (1) Precast Pier Columns: production Pier Formwork binds pier stud main reinforcement and stirrup, carries out Precast Pier Columns concreting, poured
Cheng Houyong canvas covering, it is quiet stop a period of time after, start ventilation heating it is steam-cured, after reaching 90% or more design strength, Ji Keting
It only conserves, is ensuring that concrete will not occur due to demoulding and cause can form removal after damage；(2) pier stud transports existing
: construction site is transported to using rubber-tyred transportation in assembled state vehicle, damping is spread on compartment board and prevents the rubber pad of friction, in advance
It should be fixed after pier stud entrucking processed, and fixing situation is checked, meeting can dispatch a car after transporting requirement safely；(3) structure
The storage of part scene: spaciousness is answered in the stacking place of component, stack place answer it is smooth it is solid, draining is good, for prevent Precast Pier Columns by
Pollution, divides into sleeper as support pad；(4) pile foundation, bearing platform construction: progress pile foundation construction, excavation pit carry out cushion cap bed course first
Construction binds cushion cap reinforcing bar, and by the pre-buried bellows of design position, installation platform template pours cushion cap concrete and conserves, finally
Dabbing processing is carried out to cushion cap groove inner surface；(5) hoisting prefabricated pier stud；(6) loop wheel machine is slow to cushion cap top by pier stud lower end
Transfer makes suspension centre, pier stud bottom center, 3 points of cushion cap center in same vertical line, and the overhanging main reinforcement insertion of pier stud is pre-buried
In bellows, groove center support column top surface contacts support pier stud weight with pier stud bottom surface；(7) it is fixed temporarily and corrects: pier shaft
Surrounding is fixed using diagonal brace, and four foot of diagonal brace is withstood with screw jack, and the verticality of pillar is detected with theodolite or total station, if
The deviation filled and be worth perhaps is had more than, pier shaft verticality is adjusted by diagonal brace；(8) connecting node is constructed: confirmation pier stud position, verticality
After repetition measurement is errorless, high-strength mortar or grouting material are poured into bellows, the notch of groove applies one layer of steel mesh, pours in groove
Build expansive concrete or ultra-high performance concrete；(9) maintenance and temporary support are removed: after the completion of groove pours, being spilt in time
Water is conserved, and outside is conserved using geotextiles plastic film of wrapping, and keeps concrete surface wet, to concrete strength
Dismountable step (7) is fixed temporarily when reaching 90%.
Preferably, in step (8), micro- promotion pier stud exposes ripple before high-strength mortar or grouting material are poured into bellows
Nozzle, after high-strength mortar or grouting material are poured into bellows, pier stud main reinforcement should the insertion before high-strength mortar or grouting material solidification
Bellows, it is closely knit to guarantee to contact to fill up bellows gap for extruding high-strength mortar or grouting material when main reinforcement is inserted into.
Compared with prior art, the invention has the following advantages: structure is simple, bellows is pipe structure, passes through pipe
Wall forms the bonding of concaveconvex shape enhancing and interior filled layer, Concrete Filled layer, being connected firmly at assembly node；So that bridge
Substructure construction assembling, realize bridge pier factory industry metaplasia produce, scene it is directly assembled, have site operation fast and safely,
, wet construction few, short construction period, component quality guaranteed, economic and environment-friendly the advantages that small to Coherent traffic noise, has good engineering
Promotion prospect.
