Description
Technical field
The invention belongs to technical field of building construction, more particularly to a kind of concrete filled steel tube with replaceable floorings
Truss combination beamss and construction method.
Background technology
Concrete-filled steel tube truss combination beam is a kind of novel bridge structure, and being completed this type bridge has dry lake grand bridge
Deng.The dead weight of the type bridge relatively reduces 50% or so with across footpath concrete beam bridge, is increasing bridge span ability simultaneously, can also subtract
Few bridge substructure quantities, therefore the bridge type has good development prospect.
Space concrete filled steel tube truss combination beamss construction both at home and abroad at present, generally first using the methods of dilatory, segmental hoisting
Steel pipe truss is set up, then the Pumping concrete into wind up pipe and the lower chord tube of steel pipe truss again, waits for that the concrete in steel pipe reaches
To after design requirement, with the support that steel pipe truss is cast-in-place floorings template, a high position sets up floorings template, cast-in-site bridge floor
Plate.Floorings are poured into a mould using the method, template installation, concrete cast are completed in high-altitude in situ, and the duration is longer, difficulty of construction
Larger, floorings construction quality is not easy to ensure, there are very big hidden danger for personnel safety and architecture quality, and change difficulty.
To shorten the construction period, ensureing floorings construction quality, floorings can also be poured before installing steel pipe truss, that is, poured
It builds the floorings of completion and steel pipe truss is drawn or lifted together and sets up.When using such construction method, floorings will increase steel
Construction weight when tubular truss is installed.Large tonnage crane segmentation can be used in place not high for bridge pier, that temporary rest pier can be arranged
Steel pipe truss of the lifting with floorings；But when bridge pier is higher or temporary rest pier cannot be arranged, using crane segmental hoisting
Method then cannot achieve, can only use it is dilatory set up, at this point, heavy weight deck structrue will produce when great cantilever will be caused to work
Raw very big internal force, causes this structural system and construction method cannot achieve, and can only use and first set up steel pipe truss, constructs pour again
Build the construction method of floorings.
In summary, it is necessary to design one kind can widen the steel pipe concrete truss structure place scope of application, shorten the construction period,
Ensure the novel mounting structure and construction method of work progress personnel safety and construction quality.
Invention content
Present invention seek to address that concrete-filled steel tube truss installation period is long in the prior art, it is serious to be limited by fabricating yard
Technical problem and construction period can be shortened, reduce difficulty of construction, can guarantee construction quality and personnel safety, reduction by providing one kind
The concrete-filled steel tube truss combination beam and construction method with replaceable floorings that construction site is required.
The present invention is adopted the technical scheme that solve technical problem present in known technology：One kind having replaceable
The top of the concrete-filled steel tube truss combination beam of floorings, including steel pipe truss, the steel pipe truss has the pipe that winds up, and further includes
Along bridge to the disconnectable floorings of polylith for being laid on the steel pipe truss top successively, it is characterised in that：It is described to wind up on pipe
It is fixed with multigroup connecting plate, there is screw hole on the connecting plate；The lower part of the floorings is equipped with and multigroup connecting plate one
