Description
Technical field
The utility model relates to a kind of cast-in-place box beam bracket, particularly a kind of mobile adjustable cast-in-place box beam bracket.
Background technology
In recent years, be inclined cross or bridge across active service highway cast-in-place construction increasing, due to the importance of current highway communication, all require be inclined cross or across bridge construction process in can not carry out road closed, affect the normal operation of highway, and require be inclined cross or across bridge construction process in need to reach certain headroom standard and span standards, in order to avoid affect convenience and the safety of highway driving, be subject to not allowing long-term road closure, the restriction of bridge down train headroom and the many factors such as curb-to-curb width and construction interference, it is the Focal point and difficult point in construction that support in construction of cast-in-situ box-beam is set up always.
At present, a kind of support cast-in-place of normal employing Construction Technique of Box deals with the complexity of current construction, this kind of support is by temporary rest pier, stressed truss, suspension system and template are formed, the requirement of bridge down train headroom and curb-to-curb width can be met by rational layout, in the art, the size of bridge down train headroom and curb-to-curb width is related between the position of stressed truss, but the stressed truss in this technology is dead fixing, once after rack construction, cannot regulate stressed truss in vertical and horizontal direction position, therefore, if when there are special circumstances during bridge construction, the position of current stressed truss possibly cannot meet the requirement of bridge down train headroom and curb-to-curb width, this just requires to possess mobile adjustability at stressed truss in the construction period of cast-in-situ box girder, meet in work progress in particular cases strain capacity.
To sum up, need badly at present and seek a kind ofly to possess stressed truss and move cast-in-place box beam bracket that is adjustable, that do not increase again cost and seem very important.
Summary of the invention
In order to overcome above defect, the purpose of this utility model is to provide a kind of mobile adjustable cast-in-place box beam bracket, constructs convenient.
The utility model is achieved through the following technical solutions:
A kind of adjustable mobile cast-in-place box beam bracket, primarily of basis, Temporary Piers, jack, track, stressed truss, lower hanging beam, suspension rod and driving electric car composition;
Wherein, Temporary Piers is arranged in basic top, and jack is arranged on above Temporary Piers, and rail bracket is located between two jack, and stressed truss arrangement is side in orbit; Lower hanging beam is directly connected to the upper hanging stick of stressed truss by suspension rod and antilift wire;
Every 2-3 stressed truss, configure a driving electric car, bottom the lower hanging stick of stressed truss, be provided with slip wheel simultaneously, slip wheel can slide along the track, and stressed truss web is connected with the link driven outside electric car.
Aforesaid adjustable mobile cast-in-place box beam bracket, is provided with and drives wheel and braking bottom driving electric car.
Aforesaid adjustable mobile cast-in-place box beam bracket, track is fixed on jack top by fixing feet.
Aforesaid adjustable mobile cast-in-place box beam bracket, described Temporary Piers is two steel pipes be arranged side by side.
Aforesaid adjustable mobile cast-in-place box beam bracket, does not arrange lower hanging beam and suspension rod driving the stressed truss in electric car linkage section.
The utility model is by driving electric car, slip wheel and jack, realize movement upper and lower before and after stressed truss, achieve the mobile adjustable of cast-in-place box beam bracket, can the on-the-spot headroom of real-time monitoring, under the condition not affecting highway normal operation, complete the construction working of cast-in-situ box girder.
It is inner that driving electric car of the present utility model is arranged in stressed truss, is connected by the web member of link with stressed truss, ensure that the Movement consistency and cooperative bearing distortion that drive electric car and stressed truss.
Suspension rod and lower hanging beam are directly fixed on the upper hanging stick of stressed truss by arranging antilift wire on stressed truss top by the utility model, increase distribution beam more, simplify construction technology without the need to again.

Detailed description of the invention
With reference to Fig. 1, adjustable mobile cast-in-place box beam bracket, be inclined cross on direction every 11.5m at case beam, the basis 1 of length × wide × height=2.2m × 1.1m × 0.8m is set, one group of basis 1 is set in highway operation direction, the spacing of basis 1 in highway operation direction is 6.75m, after the construction of basis 1, two length 5m are installed side by side on each basic 1, diameter 500mm, wall thickness 9mm, the steel pipe of spacing 1m is as Temporary Piers 2, the spacing of two steel pipes is 1.5m, each Temporary Piers 2 is all arranged the electronic hydraulic jack 3 of more than one group of 500 tons of range, and by fixing feet 4 welded rails 5.
The gradation of SKR-6 military beam is adopted to assemble stressed truss 6, each stressed truss 6 element length is 4m, often assemble what a stressed truss element just by this unit lifting in existing track 5, and when assembling stressed truss 6, every 2m arrange one group of diameter be the slip wheel 7 of 20cm in the lower hanging stick of stressed truss 6, slip wheel 7 is arranged in track 5; Arrange the driving electric car 10 of 240 horsepowers between two or three stressed truss 6 unit every, drive electric car and stressed truss to be fixed as one by link 13, link is arranged on and drives outside electric car, is connected with the web member on stressed truss.Drive on electric car 10 and be provided with driving wheel 14 and braking 9, drive electric car 10 along orbital motion, can ensure that stressed truss 6 horizontal direction moves and brakes.
After stressed truss 6 has lifted, at the upper hanging stick of stressed truss 6, an antilift wire 11 is set every 1.5m, by antilift wire 11 connection diameter be 18cm, length is the suspension rod 12 of 1.2m, it is 8.5m, the lower hanging beam 8 adopting the making of 22b i iron that suspension rod 12 lower end is connected to length, lower hanging beam 8 should be in top about the 30cm of stressed truss 6 times hanging sticks, finally completes mobile adjustable cast-in-place box beam bracket.
Above-mentioned detailed description of the invention does not limit the technical solution of the utility model in any form, and the technical scheme that the mode that every employing is equal to replacement or equivalent transformation obtains all drops on protection domain of the present utility model.
