Description

A kind of corrugated steel web plate composite box girder
Technical field
The utility model relates to a kind of corrugated steel web plate composite box girder, belongs to bridge construction field.
Background technology
Traditional corrugated steel web plate composite box girder top flange adopts open pore steel plate to wear the PBL connector of transverse reinforcement, bottom flange is directly worn transverse reinforcement at steel web holes and is formed PBL connector, the Main Function of PBL connector is Transfer of Shear, bear the cross section longitudinal shear between edge of a wing steel plate and concrete slab, the straight skidding that both constraints are mutual, ensures that steel-concrete combined structure reaches compatibility of deformation, jointly stressed effect.But, conventional P BL connector is in practice of construction process, make the reinforced mesh difficult arrangement in upper and lower concrete slab, particularly transverse reinforcement is difficult to through perforate mouth, difficulty of construction is large, cause steel reinforced concrete connecting portion place construction quality to be difficult to ensure, affect the stress performance of structure, reduce safety and the durability of structure.These problems cause certain difficulty all to applying of this class formation.
Utility model content
The technical problem that the utility model solves is that provide a kind of combined box beam of constructability, construction quality more easily ensures, keep the performance of the Transfer of Shear that steel reinforced concrete connecting portion is good simultaneously, have more superior safety and durability, simple structure, economic performance is more excellent.
The technical solution of the utility model is, a kind of corrugated steel web plate composite box girder is provided, comprise top flange concrete slab and bottom flange concrete slab, Wavelike steel webplate between top flange concrete slab and bottom flange concrete slab, the top flange steel plate on Wavelike steel webplate top, the bottom flange steel plate of bottom, vertical steel plate established by top flange steel plate, the welding of vertical steel plate side or riveted joint the first peg, the welding of Wavelike steel webplate side or riveted joint the second peg, the first peg and the second peg lay respectively at the inside of top flange concrete slab and bottom flange concrete slab.
Further, the first peg and the second peg are vertical with Wavelike steel webplate with vertical steel plate respectively.
Further, top flange steel plate is all vertical with Wavelike steel webplate with bottom flange steel plate, welds two blocks of vertical steel plates be parallel to each other in the upside of each block top flange steel plate.
Further, the first peg is welded respectively in the outside of two blocks of vertical steel plates be parallel to each other.
Further, the second peg is all welded in the both sides of Wavelike steel webplate.
The construction sequence of the combined box beam that the utility model provides is:
A. the processing of steel work is carried out at precasting yard, by Wavelike steel webplate and top flange steel plate, bottom flange Plate Welding integrally, vertical steel plate is welded, below the steel plate of bottom flange, Wavelike steel webplate lower side and vertical steel plate side melting welding peg (comprising first, second peg) above the steel plate of top flange;
B. the making of bottom flange concrete slab is carried out at the construction field (site): set up temporary support erection template, assembling reinforcement mesh sheet, then concreting, form bottom flange concrete slab;
C. top flange concrete slab is made: make temporary support erection template with mounted steel web, arrange reinforced mesh, pre-buried presstressed reinforcing steel bellows, concreting, form top flange concrete slab;
D. presstressed reinforcing steel is penetrated and stretch-draw, the corrugated steel web plate composite box girder described in formation.
The utility model has following advantage relative to prior art: (1) the utility model in steel reinforced concrete junction by transverse reinforcement directly and welding of peg or riveted joint, avoid transverse reinforcement through this numerous and diverse operation of open pore steel plate, accelerate construction speed, shorten the duration.(2) due to vertical steel plate sidepiece peg, Wavelike steel webplate bottom sides peg are arranged along case beam longitudinal separation, steel reinforced concrete junction by transverse reinforcement mesh sheet directly and welding of peg or riveted joint, therefore can be the reinforced mesh in concrete slab, particularly the layout of transverse reinforcement provides sufficient space, be convenient to the construction of concrete slab, reduce difficulty of construction, improve construction quality.(3) due in case beam top flange and steel reinforced concrete junction, bottom flange by transverse reinforcement mesh sheet directly with welding of peg or riveted joint, make its switching performance more reliable, ensure that steel-concrete combined structure is out of shape and more coordinate, stressed more reasonable.(4) because Wavelike steel webplate side peg and bottom flange steel plate lower peg are arranged along case beam longitudinal separation, bottom flange concrete slab 3 maintains good globality, improves safety and the durability of combined box beam.
