Description
Technical field
The present invention relates to Construction of continuous beam technical field, and in particular to a kind of ultrashort closure segment of rotator construction bridge.
Background technology
Conventional continuous beam in construction, it is necessary to carry out swivel closure, due to the rotating body beam body end face at both ends be with it is common
Rectangular cross section, in order to turn when, do not interfere, and pour that to close up gap wider after reserved, pour closure segment after causing and construct
Journey is complicated.It is existing to be typically employed in that full framing at bridge location is cast-in-place or segmented Cantilever Casting Construction method, if bridge is crossed over
Important building, such as high-speed railway, certainly will operate existing building and produce considerable influence, and security is difficult to be protected.
Rotator construction is used in order to reduce the interference to existing highway or high-speed railway, reduce influences its volume of operation to greatest extent,
Continuous beam closure section construction carries out continuous beam after formwork is carried out on closure hanger using closure hanger as carrier at present
Closure, but progress closure section construction will carry out pipe canopy protection to existing railway or highway above existing railway or highway.And manage
The construction of canopy will interfere existing railway or highway, so produce certain influence to the superiority of rotator construction, especially
The high-speed railway being across in operation, constructs in limited " skylight " time, and this influence is just more obvious.
The content of the invention
In order to solve the above technical problems, the closure segment construction time is poured after being reduced the present invention provides one kind, reduction pair
The ultrashort closure segment for the rotator construction bridge that line of operating disturbs.
A kind of ultrashort closure segment of rotator construction bridge of the present invention, its technical solution are：Including the first swivel beam body, second
Beam body and the closure segment for connecting the first swivel beam body and the second swivel beam body are turned, the closure segment includes first pouring closure segment
Closure segment is poured with after, the closure segment that first pours is divided into left half range and right half range, the first rotating body beam body end along bridge longitudinal axis
Portion is fixedly connected with left half range one end, and the second rotating body beam body end portion is fixedly connected with right half range one end, first swivel
Poured after being formed after beam body, the second swivel beam body are rotating closed and close up gap, poured to pour after closure segment is arranged at after described and close up gap
It is interior, and left half range, right half range, the first swivel beam body, the second swivel beam body are connected to form a continuous beam entirety.
Further, it is equipped with the left half range and the opposite side of right half range and closes up buffer stopper, the left half range
The buffer stopper that closes up for closing up buffer stopper and right half range shifts to install, and the thickness for closing up buffer stopper is poured with after closes up gap width
Unanimously.
Further, the first swivel beam body and left half range section are embedded with the first temporary fastening device, second swivel
Beam body and right half range section relevant position be embedded with matched second temporary fastening device of the first temporary fastening device, described
One temporary fastening device and the second temporary fastening device exposed parts are fixedly connected, first temporary fastening device and second
Temporary fastening device is symmetrical both with respect to bridge longitudinal axis.
Further, first temporary fastening device and the second temporary fastening device are angle steel or channel steel, the angle
Steel or the dislocation welding of channel steel exposed parts.
Further, the first swivel beam body and left half range section are embedded with the first embedded bar, second swivel
Beam body and right half range section relevant position are embedded with and matched second embedded bar of the first embedded bar, first pre-buried steel
Muscle and the second embedded bar exposed parts tie up reinforcing bar after being vertically banded with, and closure segment bar-mat reinforcement is poured after formation.
Further, the left half range is included positioned at the left half range main body of bridge longitudinal axis side and positioned at bridge longitudinal axis
The right half range of opposite side avoids slopes, and the right half range includes avoiding the corresponding right half range main body of slopes and with left half with right half range
The corresponding left half range of width main body avoids slopes, and the right half range avoids slopes and left half range avoids slopes with bridge side in blunt
Angle, the end face of the left half range main body are to avoid the slopes slope that to break face parallel, the end of the right half range main body with left half range
Face is to avoid the slopes slope that to break face parallel with right half range.
Further, structure is distinguished between the left half range and the first swivel beam body, between right half range and the second swivel beam body
Into two cascaded surfaces, two cascaded surfaces are mutually twisted with the rotation of the first swivel beam body and the second swivel beam body, and
Occlusion position is poured after being formed closes up gap.
Beneficial effects of the present invention：Closure segment is first poured using what left half range and right half range were formed, two sections is greatly reduced and turns
Interference of the body beam body in swivel, pours after making and closes up gap and greatly reduce.Closure segment is poured without closing up after construction is shorter
Hanger, only can complete construction at this stage with easy template, save steel, cost is low, largely reduces closure segment
Construction time.It is not required to set weight, simplifies construction process.It is simple to change traditional external stiff skeleton locking device
Embed-type pre-embedded device, saves steel, simplifies construction process.After pour and close up gap longitudinal lap joint horizontal meaders, there is anti-mistake to turn
Function, solves conventional rotator construction and crosses and turn problem, reduces construction risk.Occurred in special circumstances after turning, and be easy to adjust
Correction.
