Work holdup phenomenon to be caused；For effective lifting construction efficiency, shortens the completion time of project, pass through technical research, box
The binding of framework of steel reinforcement, using the segmented precast assembly method of a set of box beam bottom web reinforcement: by making steel bar framework of box beam
Binding positioning moulding bed, is positioned using mould, whole to carry out merogenesis binding to bottom web reinforcement skeleton, the waiting after box girder webs
It draws and mould bases walks, molds, carries out reinforcing bar binding during mode transfer, become parallel operations from continuous productive process, reduce caused by waiting
Work holdup phenomenon achievees the purpose that accelerate construction progress, and the bottom that has bound, web reinforcement skeleton hold during being hoisted to fetal membrane
It easily deforms and distorts, be difficult that box beam reinforcement installation qualification rate is effectively ensured, and bring to construction safety and construction quality
Hidden danger.
Summary of the invention
The object of the present invention is to provide a kind of box beam bottom web reinforcement lifting devices, can effectively ensure cast-in-situ box girder reinforcing bar
Skeleton does not deform in hoisting process ensure that construction quality, increase construction safety, and hoisting process is steadily safe.
In order to achieve the above objectives, the technical solution adopted by the present invention is that:
A kind of box beam bottom web reinforcement lifting device, including several lifting elements disposed in parallel lead between multiple lifting elements
Top boom disposed in parallel up and down is crossed to be fixedly connected with lower boom, it is vertical between the top boom, lower boom and lifting elements to set
It sets, the cross section of the lifting elements is isosceles trapezoid, and lifting elements top surface is additionally provided with multiple lifting hanging rings.
Further, the lifting elements include upper and lower first crossbeam and second cross beam disposed in parallel, first crossbeam
Length is less than the length of second cross beam, is fixedly connected between first crossbeam and second cross beam by multiple first support bars, described
It is vertically arranged between first support bar and first crossbeam, the first crossbeam end and second cross beam end are additionally provided with connection waist
Beam, the first crossbeam, second cross beam, both ends waist rail composition isosceles trapezoid lifting elements.
Further, multiple braces are additionally provided between the first crossbeam and second cross beam, the top boom is fixedly welded
In first crossbeam bottom, the lower boom, which is fixedly welded between second cross beam bottom, top boom lower boom, is additionally provided with second
Strut, the second support bar top are fixedly connected with top boom, and second support bar lower part is fixedly connected with second cross beam.
Further, the hanging ring is set at the top of first crossbeam, and gusset is additionally provided between hanging ring and first crossbeam.
Further, the quantity of the top boom and lower boom be three, three top booms along first crossbeam length
Direction is uniformly arranged, and lower boom is arranged in a one-to-one correspondence up and down with top boom position.
Further, the lifting elements are nine, and nine lifting elements are uniformly arranged along top boom length direction.
Present invention has the advantage that
1, box beam bottom web reinforcement lifting device lifting reinforcing bar is integrally more stable, safe and reliable, can effectively avoid in hoisting process
Middle framework of steel reinforcement is deformed and is distorted；
2, box beam bottom web reinforcement lifting device is made into two-tier truss structure, and it is small to make up combination beam suspender stiffness by itself, easily-deformable
Defect.The effect of material can be given full play to, material is saved, mitigates self weight, increases rigidity；
3, the present apparatus is practical, and structure is simply convenient for promoting.
