Description
Technical field
The hoisting structure of a kind of pier stud reinforcing cage of the utility model, be more particularly a kind of when being applied in cushion cap pier stud integrated construction in pier stud reinforcing cage whole lifting structure.
Background technology
Cushion cap pier stud integrated construction is that one can greatly reduce construction operation amount on construction supplementary structure and bridge, thus the technique significantly improving working conditions, speed up the work, save the operation of manually taking and tearing pier shaft scaffold open, reduce high-rise working risk; Reduce the duration, simple to operate, save labour, save consumptive material and drop into.
Pier stud reinforcing cage has top vase pier usually and the external diameter that connects with vase pier is less than the neck of vase pier, cushion cap pier stud integrated construction is in construction bearing platform process, will by the integral hoisting of pier stud reinforcing cage in cushion cap reinforcing bar, and can guarantee that pier stud reinforcing cage is indeformable in handling, but, the open report of not relevant integral hoisting method so far, because pier stud reinforcing cage overall weight and volume are all very large, suspension centre is directly set on pier stud reinforcing cage and is difficult to ensure that pier stud steel bar overall is indeformable.
Such as, in the elevated project in line interval, Beijing Metro swallow room, this project interval is all ground elevated project, and substructure is pile foundation, cushion cap and pier stud, without bent cap.In cushion cap reinforcement construction, show in conjunction with Beijing meteorological data, local wind-force rank reaches 3 ~ 4 grades, each pier stud reinforcing cage weight is between 7.546t ~ 24.567t, if conveniently the direct mode lifted pier stud reinforcing cage will cause pier stud reinforcing bar hoisting process to produce distortion, meanwhile, cannot lift in enormous quantities, therefore programming is affected.
Utility model content
The utility model is the weak point for avoiding existing for above-mentioned prior art, provides a kind of pier stud reinforcing cage whole lifting structure, pier stud reinforcing cage can be put in place fast in handling, and guarantee that pier stud reinforcing bar is indeformable, thus ensure programming, improve workmanship.
The utility model is that technical solution problem adopts following technical scheme:
The feature of the utility model pier stud reinforcing cage whole lifting structure is: be bolted formation one with Two bors d's oeuveres channel-section steel and close and enclose frame (4), the neck that frame (4) is fixed on pier stud reinforcing cage vase pier (1) is enclosed with described closing, and to form the closed stirrup cross-arm of Two bors d's oeuveres channel-section steel as vase pier (1) enclosing frame (4); Described closed enclosing on frame (4), each hanger is set, hoisting wirerope (2) is located in described each hanger, lifting appliance utilizes described hoisting wirerope (2) to lift by crane and closes and encloses frame (4) and make pier stud reinforcing cage (6) in vertical handling, and the described shape of enclosing frame (4) and described pier stud reinforcing cage vase pier (1) of closing matches; Cable wind rope (5) for drawing pier stud reinforcing cage (6) is fixedly connected on and is positioned over ground concrete precast block (10).
The feature of the utility model pier stud reinforcing cage whole lifting structure is also:
The square that described concrete precast block (10) is the length of side is 1.5m, weight is 8.5 tons, arrange suspension ring in the surrounding of described concrete precast block (10), cable wind rope (5) is fixedly connected on described suspension ring.
Described closed enclosing in frame (4), " ten " word is provided with dowel (7), keep closing that to enclose frame (4) indeformable with the booster action of described dowel (7), described dowel (7) adopts fining twisted steel.
For pier stud reinforcing cage vase pier (1) that end face is rectangular, described closing encloses frame (4) rectangle frame also for matching.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model is hung by pier stud reinforcing cage with channel-section steel cross-arm, lifting transhipment is carried out with hanger, the frame that encloses that its shaped steel is formed ensure that pier stud reinforcing cage is firmly integrally-built, enclose between frame and pier stud reinforcing cage and form multiple origin of force, effectively ensure that in pier stud reinforcing cage handling process indeformable; Concrete precast block is adopted to fix cable wind rope, safe and reliable, can be used for the more location of underground utilities, need not earth anchor be set up.
2, the utility model can be reused, and substantially increases operating efficiency, provides sound assurance for coordinating programming;
3, the pier stud reinforcing cage vase pier in handling is enclosed in and encloses on cross-arm that frame formed by closing by the utility model, and handling process safety is reliable; Its structure is simple, easy to implement.

Detailed description of the invention
See Fig. 1, Fig. 2 and Fig. 3, the present embodiment pier stud reinforcing cage whole lifting structure is bolted formation one with Two bors d's oeuveres channel-section steel to close and enclose frame 4, the neck that frame 4 is fixed on the vase pier 1 of pier stud reinforcing cage 6 is enclosed to close, and to form the closed stirrup cross-arm of Two bors d's oeuveres channel-section steel as vase pier 1 enclosing frame; Closed enclosing on frame 4, each hanger is set, hoisting wirerope 2 is located in each hanger, lifting appliance utilizes hoisting wirerope 2 to lift by crane and closes and encloses frame 4 and make pier stud reinforcing cage 6 in vertical handling above cushion cap 9, and the closed frame 4 that encloses matches with the shape of pier stud reinforcing cage vase pier 1.
In concrete enforcement, " ten " word is provided with dowel 7 closing to enclose in frame 1, keeps closing that to enclose frame 4 indeformable with the booster action of dowel 7, dowel 7 adopts fining twisted steel.
As shown in Figure 2, for the pier stud reinforcing cage vase pier 1 that end face is rectangular in the present embodiment, it closes the rectangle frame enclosing frame 4 and be set to match, and is specifically bolted by the pair of beams 4A be arranged in parallel and a pair end carriage 4B and makes; In order to guaranteed strength, the dowel 7 in rectangle frame is twice " ten " word muscle, and two fining twisted steels intersected in " ten " misplace in different elevation, to ensure that fining twisted steel is straight muscle.
In order to ensure that lifting steadily, for the rectangle frame shown in Fig. 2, both sides hoisting wirerope 2 can be independently set for both sides crossbeam 4A, both sides lifting rope 2 shares the two ends at the shoulder pole 3 in level, and lifting appliance carries out lifting by the lifting wire rope 8 being arranged on the two ends of shoulder pole 3 at the two ends of shoulder pole 3.
Cable wind rope 5 for drawing pier stud reinforcing cage in the present embodiment is fixedly connected on and is positioned over ground concrete precast block 10, the square that concrete precast block 10 is length of sides is 1.5m, weight is 8.5 tons, the steel mesh reinforcement of two-layer Φ 14 is set in concrete precast block 10, suspension ring being set in the surrounding of concrete precast block 10, establishing cable wind rope 5 for drawing.Draw and set cable wind rope 5 to be impacts as ensureing pier stud reinforcing cage not by wind, earth anchor can be set up when usual cable wind rope is fixed on ground, but in the location that underground utilities are more, arrange earth anchor and probably damage underground utilities, the utility model adopts concrete precast block to address this problem.
Assembling and handling process: be transported to pier stud construction location after the colligation of pier stud reinforcing cage completes, fix by loop wheel machine supporting leg, hoisting structure installation, lifting, joint bar, cable wind rope.
