Description
Technical field
The utility model relates to bridge structure technical fields, and in particular to a kind of precast beam and be connect using the wet of the precast beam
Stitch connection structure.
Background technique
In bridge construction, due to being limited by place, traffic condition, precast bridge is usually required in lateral arrangement at more
The form of piece beam, the beam type of bridge mostly uses T-type, small box girder type etc., and prefabricated small box girder is due to its economic, spy easy to use
Favor of the point increasingly by bridge construction person.But prefabricated small box girder needs the floorings by one fixed width in direction across bridge
Cast-in-place wet seam connects multiple precast beams to form entirety, and wet seam is the seam between the adjacent box beam in left and right and box beam.
Currently, the common wet seam of prefabricated small box girder floorings mostly uses the concrete material with prefabricated beam body with label, and wet seam
The connection of interior reinforcing bar, which mainly has by the way of annular dowel, (passes through annular dowel for adjacent box girder bridge face plate reserved steel bar
Correspond binding or weld together) and the form of straight line dowel is used (to correspond box girder bridge panel reserved steel bar
Weld together).Using both welding manners, when precast beam spanning is across counting more with beam piece quantity, the work of welding
Amount is big, increases construction cost, causes the construction time longer, and construction efficiency reduces.
In view of the above-mentioned problems, the Chinese utility model patent that Authorization Notice No. is CN204530475U discloses a kind of small width
Spend the wet seam connection structure of floorings, including at least the first precast beam and the second precast beam, the first precast beam and the second precast beam
Interior transverse direction is respectively arranged with the first precast beam reserved steel bar and the second precast beam reserved steel bar for extending to outside, and first is prefabricated
The side of beam and the closely wet seam of the second precast beam is also respectively provided with horizontal with integrally formed first precast beam of the first precast beam
Section and with the integrally formed second precast beam horizontal segment of the second precast beam；It extends to first pre- outside the first precast beam horizontal segment
The end of beam reserved steel bar processed is provided with the first single annular structure, extends to the second precast beam outside the second precast beam horizontal segment
The end of reserved steel bar is provided with the second single annular structure；First single annular structure and the second single annular structure are along the vertical of wet seam
To being staggered into thimble structure.The wet seam connection structure binds longitudinal reinforcement by thimble structure, and no setting is required individually
Ring structure.But precast reinforced in the precast beam of the wet seam connection structure be not generally it is too thick, in order to guarantee the
Bonding strength between one precast beam and the second precast beam can generally select wider wet seam, this just need to be poured it is more,
The even higher concrete of intensity improves wet seam crossing stress intensity to guarantee the intensity of floorings.This is obviously close with China
Few field operation, short time limit, various consumption and the few green structure of circulation material materials is widelyd popularize over year to disagree.
