Description
Technical field
The invention belongs to the bridge technology field of highway and railway, what relate generally to is a kind of Wavelike steel webplate prestressed concrete continuous box girder and job practices.
Background technology
The Wavelike steel webplate prestressed concrete box girder is as a kind of novel steel-concrete combined structure; Concrete resistance to compression, advantage that Wavelike steel webplate shearing resistance yield strength is high have been made full use of; Effectively steel, two kinds of materials of concrete are combined; Improved the service efficiency of material, be a kind of economy, rationally, form of structure efficiently.Existing Wavelike steel webplate prestressed concrete box girder adopts two kinds of job practicess of cast-in-place and prefabricated installation usually.
As shown in Figure 1: as to adopt the Wavelike steel webplate prestressed concrete box girder member of cast-in-place method construction mainly (to be positioned at beam-ends and to be called crossbeam by Wavelike steel webplate 1, upper connector 2, following connector 3, cast-in-site concrete roof plate 7, cast-in-situ concrete base plate 8, cast-in-situ concrete crossbeam or diaphragm 9; Be positioned at span centre and be called diaphragm, as follows), presstressed reinforcing steel 11, external prestressing muscle 12 and pier top hogging moment presstressed reinforcing steel 13 are formed in the bottom-plate body.Wavelike steel webplate 1 is transported to the job site with connector 2,3 up and down and positions installation after factory's welding, set up support or adopt cantilever pouring case beam concrete.The construction of cast-in-place method exists field operation and difficulty of construction bigger; Problems such as long construction period; The joint portion of underplate concrete and following connector is because the operating space is narrow and small simultaneously, and the concrete pouring work difficulty is bigger, may have influence on joint portion Concrete Construction quality and durability of structures.
As shown in Figure 2: as to adopt the Wavelike steel webplate prestressed concrete box girder member of prefabricated mounting method construction mainly to form by Wavelike steel webplate 1, upper connector 2, following connector 3, precast concrete top board 4, precast concrete base plate 5, precast concrete crossbeam or diaphragm 6, cast-in-site concrete roof plate 7, cast-in-situ concrete crossbeam or diaphragm 9, external prestressing muscle 12 and pier top hogging moment presstressed reinforcing steel 13.Be employed in precast yard's standardization prefabricated each operation of Wavelike steel webplate prestressed concrete box girder and construction quality better assurance is all arranged; But prefabricated Wavelike steel webplate prestressed concrete box girder is for satisfying conventional erection equipment needs; Be many casees box-beam structure; Every case beam transverse width is little, and web quantity is many, and rolled steel dosage is big; Along with prefabricated case beam is striden increase directly, every case beam erection weight also increases thereupon, and conventional construction equipment has been difficult to satisfy installation requirement.These problems have caused certain difficulty for applying of this class formation.
Summary of the invention
The present invention is directed to the deficiency that prior art exists; A kind of continuous box girder and job practices that is made up of Wavelike steel webplate prestressed concrete i beam is provided; It had both had corrugated web PC Box Girder Structure advantage; Can effectively overcome the problem that above-mentioned cast-in-place and prefabricated Wavelike steel webplate prestressed concrete box girder runs into again, have that stress performance is good, stock utilization is high, easy construction is quick, the characteristics of remarkable in economical benefits.
The present invention realizes that the technical scheme that above-mentioned purpose is taked is: will set up after reinforcing bar is fixedly connected in transverse reinforcement and the corresponding cast-in-place member of precast concrete top board, precast concrete base plate, precast concrete crossbeam or diaphragm of adjacent two Wavelike steel webplate prestressed concrete i beam unit of installation; By the cast-in-situ concrete base plate between the cast-in-site concrete roof plate between the contiguous prefabricated concrete roof, the contiguous prefabricated concrete floor; Cast-in-situ concrete crossbeam between contiguous prefabricated concrete beam or the diaphragm or diaphragm connect the back and form closed case beam; External prestressing muscle in the closed case beam of stretch-draw and anchoring; With connecting through building the cast-in-situ concrete longeron between the closed case beam in adjacent two holes; Stretch-draw and anchoring pier top hogging moment presstressed reinforcing steel form continuous box girder.
The job practices of above-mentioned Wavelike steel webplate prestressed concrete continuous box girder is: with above-mentioned a plurality of i beams unit set up be installed on the Bridge Pier after; After reinforcing bar in the transverse reinforcement of precast concrete top board, precast concrete base plate, precast concrete crossbeam or the diaphragm of the adjacent i beam of direction across bridge unit and the corresponding cast-in-place member is fixedly connected; Through building cast-in-site concrete roof plate between the contiguous prefabricated concrete roof, between contiguous prefabricated concrete floor, building the cast-in-situ concrete base plate, after building cast-in-situ concrete crossbeam or diaphragm between contiguous prefabricated concrete beam or the diaphragm, promptly form closed case beam; External prestressing muscle in the closed case beam of stretch-draw and anchoring; With connecting through building the cast-in-situ concrete longeron between the closed case beam in adjacent two holes, stretch-draw and anchoring pier top hogging moment presstressed reinforcing steel are removed temporary support, carry out the system conversion, form continuous box girder.According to the wide difference of bridge, bridge laterally can be made up of single or a plurality of closed case beams, and the connected mode between connected mode between casing and i beam unit is basic identical.
The present invention has adopted Wavelike steel webplate prestressed concrete continuous box girder elder generation " breaking the whole up into parts ", and the form of construction work of " turning parts into the whole " again has following advantage than prior art:
(1) prefabricated i beam unit process vertical, horizontal cast-in-situ concrete connects, and forms continuous unitary closed case beam, and section rigidity is relatively large, has supporting capacity height, little, the comfortable advantage of driving a vehicle of distortion.
(2) Wavelike steel webplate prestressed concrete continuous box girder bridge second phase dead load and mobile load are by the case joist support load that forms; Prefabricated i beam only need be born dead load and working load; So every i beam sectional dimension is little, erection weight is light, and conventional construction equipment just can satisfy installation requirement.The corresponding Wavelike steel webplate prestressed concrete box girder that enlarged is again striden the footpath scope of application, has the particular structure advantage.
(3) structural key parts i beam adopts prefabricated; Be connected to form whole case beam through cast-in-place; Realized the construction of breaking the whole up into parts of Wavelike steel webplate prestressed concrete box girder has been enlarged the range of application of prefabricated construction method, be beneficial to batch production processing; Effectively guarantee construction quality, accelerated construction speed.
(4) I beam part adopts the Wavelike steel webplate combining structure, has given full play to the service efficiency of steel and concrete material, has reduced amount of concrete, energy-conserving and environment-protective, good economy performance.
