Abstract
A kind of steel box-girder Dun Ding positioning slip support abutment, it is characterized in that described slip support abutment comprises a box prism-shaped main body, its top is fixedly connected with bottom steel box-girder, and slip support abutment has a slippage bottom surface, the slide plate layer laid under this slippage bottom surface comprises a stiff baseplate and stiff baseplate.Transpose slip support abutment reasonable in design, displacement of this steel box-girder Dun Ding is easy to adjust, its by with the slip support abutment realizing between steel box-girder being firmly connected, achieve slip support abutment in the carrying of Dun Ding to steel box-girder, the slide plate layer of its underpart effectively can reduce displacement frictional force when steel box-girder is transposed between steel box-girder and pier top, reduces difficulty of construction and improves efficiency of construction.
Description
Technical field
The utility model belongs to positioning facility during large sections steel box girder construction, is specifically related to a kind ofly possess supporting capacity and to transpose slip support abutment as passing the steel box-girder Dun Ding being subjected to displacement adjustment between steel box-girder and pier top.
Background technology
Growing along with construction industry and technology, China is in the coastal construction carrying out multiple marine elevated bridge.In order to realize high efficiency and the construction of high performance overhead girder, existing overhead road bridge generally adopts the large sections steel box-girder had compared with large span, and its length has reached more than 80 to 130 meters, and weight is up to more than 2000 tons.When adopting large-scale suspender to be carried out lifting by large sections steel box-girder to install to pier, needing to carry out positioning construction according to steel box-girder installation site, is first guide steel box-girder dropping place to the process of temporary support to be called by first rackwork just to transpose.After first positioning, by pier top accurate adjustment position system and bracket accurate adjustment position system, the elevation of beam and horizontal level are adjusted, until beam section hookup wire pictograph closes the linear process of design be called accurate adjustment position.During the construction of accurate adjustment position, according to first adjusting elevation, then adjust axis of pitch, the order finally adjusting longitudinal axis is progressively carried out, beam section accurate adjustment position process due to steel box-girder is an asymptotic process, and level positioning need be carried out repeatedly, and positioning order need adjust repeatedly according to on-site actual situations.In positioning process, Dun Ding is complete load-bearing to steel box-girder, and this just needs to adopt special device to make to carry out adjustment of displacement under compared with the hydraulic system driving of low thrust between Dun Ding and steel box-girder.
Utility model content
The utility model provides a kind of reasonable in design, displacement steel box-girder Dun Ding easy to adjust and to transpose slip support abutment, its by with the slip support abutment realizing between steel box-girder being firmly connected, achieve slip support abutment in the carrying of Dun Ding to steel box-girder, the slide plate layer of its underpart effectively can reduce displacement frictional force when steel box-girder is transposed between steel box-girder and pier top, reduces difficulty of construction and improves efficiency of construction.
The technical scheme that the utility model adopts is as follows:
A kind of steel box-girder Dun Ding positioning slip support abutment, it is characterized in that described slip support abutment comprises a box prism-shaped main body, its top is fixedly connected with bottom steel box-girder, and slip support abutment has a slippage bottom surface, the slide plate layer laid under this slippage bottom surface comprises a stiff baseplate and stiff baseplate.
Concretely, described slip support abutment is prism-shaped casing always, and its inside is provided with steel reinforcing segments plate.
In one embodiment, the upper weld of described slip support abutment fixes a slip base top board, and the size of this slip base top board is greater than the cross section of described box prism-shaped main body.
In one embodiment, carry out bolt by multiple high-strength bolt of arranging of distributing between described slip base top board and steel box-girder base plate and fix.
In another embodiment, between described slip base top board and steel box-girder base plate, be also equipped with reinforcement steel plate, slip base top board, strengthen being fixedly installed by high-strength bolt between steel plate and steel box-girder base plate.
Again in an embodiment, described slide plate layer is and the positioning tetrafluoro slide plate be fixedly connected with between described stiff baseplate.
This steel box-girder Dun Ding slip support abutment of transposing has the box prism-shaped main body of steel structure, can carry the weight of steel box-girder, and it to be fixed on bottom steel box-girder and with steel box-girder synchronous shift.The slide plate layer laid bottom slip support abutment provides lower force of sliding friction, again slip support abutment can carry out low frictional slip.Four sides of slip support abutment, as the work plane of hydraulic pushing system, are born and transmit displacement drive power.For ensureing effective transmission of displacement drive power, the utility model adopts slip base top board and adopts multiple high-strength bolt to be fixed the mode be connected between steel box-girder base plate to realize, more can pass through cushioning one between and strengthen steel plate, the fastness that both increases connect and stability.
The beneficial effects of the utility model are, transpose slip support abutment reasonable in design, displacement of this steel box-girder Dun Ding is easy to adjust, its by with the slip support abutment realizing between steel box-girder being firmly connected, achieve slip support abutment in the carrying of Dun Ding to steel box-girder, the slide plate layer of its underpart effectively can reduce displacement frictional force when steel box-girder is transposed between steel box-girder and pier top, reduces difficulty of construction and improves efficiency of construction.
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
Accompanying drawing explanation
Fig. 1 is the part-structure schematic diagram of the utility model detailed description of the invention.
Detailed description of the invention
As shown in Figure 1, this steel box-girder Dun Ding positioning slip support abutment has a box straight quadrangular shape main body 10, i.e. straight quadrangular shape casing, and in case, inside is provided with steel reinforcing segments plate.Its top is fixedly connected with bottom steel box-girder, and the upper weld of slip support abutment fixes a slip base top board 11, and the size of this slip base top board 11 is greater than the cross section of described box prism-shaped main body 10.Be equipped with between slip base top board 11 and steel box-girder base plate 30 and strengthen steel plate 20, slip base top board, strengthen being fixedly installed by multiple high-strength bolt 40 arranged that distributes between steel plate and steel box-girder base plate.Slip support abutment has a slippage bottom surface, the slide plate layer 13 that this slippage bottom surface is laid under comprising a stiff baseplate 12 and stiff baseplate.Slide plate layer 13 is and the positioning tetrafluoro slide plate be fixedly connected with between described stiff baseplate.
