Abstract
A kind of jack support platform of hollow slab girder jack-up construction, belongs to engineering construction technology field.The jack support platform of the hollow slab girder jack-up construction is integral type structure, its top is zigzag support platform, bottom is web, bracket plate is provided between the lower cross plate bottom surface of zigzag support platform and web front surface, stiffener is provided with zigzag support platform and web two sides, zigzag support platform and web are provided with a plurality of bolts hole.Zigzag support platform can be made using high-carbon cobalt-containing super-hard structural section entirety Forging Technology, and good integrity, rigidity is big, is unlikely to deform.Improve construction precision and security performance；The utility model can be directly by the use of former bridge coping as brace foundation basic without applying other, conveniently, safely.The utility model light structure, it is convenient during construction to install, dismantle, different jack can be carried, reuse, strong applicability.
Description
Technical field
The utility model belongs to engineering construction technology field, and thousand are laid during jack-up construction when being related to exchanging bridge abutment
The device on jin top, more particularly, to a kind of jack support platform of hollow slab girder jack-up construction.
Background technology
At present, Hollow Slab Beam Bridge more long of many service times needs replacing time, or Promotion Transformation.It is usual during construction
Using casting concrete basis, bracing members are erected as jack support platform；Or largely drill to hang steel in bent cap
Bracket is used as jack support platform.There is obvious shortcoming in these working measures：Casting concrete basis, erect bracing members into
This is higher, time-consuming to take a lot of work；Largely drilled in bent cap and hang steel bracket, easily former bent cap is caused to damage, the former bridge construction of influence
Safety can be used with the later stage.
The content of the invention
The purpose of this utility model is that offer is a kind of to be applied with simple and quick, convenient, low cost hollow slab girder jacking
The jack support platform of the hollow slab girder jack-up construction of work.
To achieve the above object, the utility model is adopted the following technical scheme that：
A kind of jack support platform of hollow slab girder jack-up construction, is integral type structure, and its top supports for zigzag
Platform, bottom is web, bracket plate is provided between the lower cross plate bottom surface of zigzag support platform and web front surface, in zigzag branch
Support platform and web two sides are provided with stiffener, and zigzag support platform and web are provided with a plurality of bolts hole.
Further：
To mitigate member dead weight, it is easily installed, dismantles, the zigzag support platform is provided with area of knockout；The web
It is provided with area of knockout.
Compared with the prior art, the utility model has the advantages that：
Jack support platform when the utility model is applied to hollow slab girder jack-up construction；
Zigzag shape support platform upper flat plate directly can be hung on bridge coping, used as main bearing member, zigzag branch
Support platform and belly steel plate anchor bolt are used for interim fixed support platform, not as main bearing member, so quantity is few, apply
In man-hour, drilled on bent cap shallow, structural damage will not be caused to bent cap.Zigzag support platform can use high-carbon cobalt-containing super-hard
Structural section entirety Forging Technology is made, and good integrity, rigidity is big, is unlikely to deform.Improve construction precision and security performance；
The utility model can be directly by the use of former bridge coping as brace foundation basic without applying other, conveniently, safely.This practicality
New structure is light and handy, convenient during construction to install, dismantle, and can carry different jack, reuses, strong applicability.
Brief description of the drawings
Fig. 1 is the dimensional structure diagram of the utility model embodiment.
Fig. 2 is the utility model embodiment positive structure diagram.
Fig. 3 is the utility model embodiment side structure schematic view.
Specific embodiment
Referring to Fig. 1~3, a kind of jack support platform of hollow slab girder jack-up construction described in the present embodiment is integrated
Formula steel plate structure, its top is zigzag support platform 1, and bottom is web 2, the lower horizontal version bottom surface of zigzag support platform 1 and abdomen
2 bracket plates 3 are welded between plate, stiffened steel plates 4 are provided with zigzag support platform 1 and the two sides of web 2, zigzag support is flat
Platform 1 and web 2 are provided with a plurality of bolts hole 5, and bolt hole 5 wears fixed and determines jack support platform for anchor bolt when constructing
1。
To mitigate member dead weight, it is easily installed, dismantles, the middle riser of zigzag support platform 1 is provided with area of knockout 11,
Web 2 is provided with area of knockout 21.
