Description
Technical field
This utility model be related to technical field of building construction and in particular to a kind of urban viaduct steel box-girder install auxiliary
Device.
Background technology
Urban viaduct steel box-girder is installed and need to be set up falsework, falsework crossbeam is installed regulation steel pipe or husky tank enters
High being accurately positioned of rower, cannot be carried out after steel box-girder component in lifting adjusting.Because falsework is held by load after lifting
Local is easily occurred to settle, workmen is installing the factors such as artificial deviation when adjusting steel pipe, after causing lifting there is weld seam interface
There is deviation in mismatch or installed height mark, scene need to carry out the centering of steel box-girder absolute altitude and weld seam interface.Looking for after steel box-girder dropping place
Positive regulator is wasted time and energy, and virtually increased construction cost.During steel box-girder unloading, such as adjusting steel pipe need to be cut, and husky tank enters
Row puts husky operation, during be difficult to control to, there is potential safety hazard.
This utility model can replace generally adjusting the devices such as steel pipe, husky tank used in steel box-girder installation process at present,
Realize quickly carrying out ascending, descending regulation to steel box-girder in installation process, and can repeat to make after steel box-girder unloading falsework is removed
With.
Content of the invention

The auxiliary device that city's overpass steel box-girder is installed, this apparatus structure is simple, and installation operation is convenient, improves production efficiency, can
Realize installation, dismounting and reuse quick and portably.
This utility model be employed technical scheme comprise that by solving above-mentioned technical problem：
The auxiliary device that a kind of urban viaduct steel box-girder is installed, including upper plate, sleeve pipe and base, upper plate and sleeve pipe
Upper end connect, the lower end of sleeve pipe is connected with base, is provided with multiple jack between upper plate and base, and jack with sleeve pipe is
Center is circumferentially distributed, and sleeve pipe can stretch up and down, by jacking or the decline of jack, so that upper plate is risen or fallen along sleeve pipe.
By such scheme, described sleeve pipe includes the first steel pipe and the second steel pipe, and the upper end of the first steel pipe is connected with upper plate,
The upper end socket of the lower end of the first steel pipe and the second steel pipe, the lower end of the second steel pipe is connected with base, and the first steel pipe can be along the
Two steel pipes move up and down.
By such scheme, between upper plate and the first steel pipe, it is provided with multiple upper gussets.
By such scheme, between base and the second steel pipe, it is provided with multiple lower web plates.
By such scheme, described jack number is 3～5.
This utility model has the advantages that：
Steel box-girder is positioned on upper plate, by jacking or the decline of jack, realizes rising or falling of steel box-girder
Adjustment, the steady control of the centering to steel box-girder welding junction and installed height mark, and carry out steadily controlled unloading after installation is complete
Carry, improve production efficiency, this apparatus structure is simple, installation operation is convenient, be capable of installation quick and portably, dismounting and weight
Multiple use.

Specific embodiment
With reference to the accompanying drawings and examples this utility model is described in detail.
Shown in reference Fig. 1～Fig. 6, the auxiliary device that urban viaduct steel box-girder described in the utility model is installed, including
Upper plate, sleeve pipe and base, upper plate is connected with the upper end of sleeve pipe, and the lower end of sleeve pipe is connected with base, upper plate and base it
Between be provided with multiple jack, jack is circumferentially distributed centered on sleeve pipe, and sleeve pipe can stretch up and down, by the jacking of jack or
Decline, so that upper plate is risen or fallen along sleeve pipe；Steel box-girder is positioned on upper plate, by jacking or the decline of jack, real
The adjustment rising or falling of existing steel box-girder, the steady control of the centering to steel box-girder welding junction and installed height mark, and in peace
Carry out steadily controlled unloading after installing into, improve production efficiency, this apparatus structure is simple, installation operation is convenient, is capable of
Installation, dismounting and reuse quick and portably.
Further, described sleeve pipe includes the first steel pipe and the second steel pipe, and the upper end of the first steel pipe is connected with upper plate, the
The lower end of one steel pipe is socketed with the upper end of the second steel pipe, and the lower end of the second steel pipe is connected with base, and the first steel pipe can be along second
Steel pipe moves up and down.
Further, the outer ring of the first steel pipe lower end is socketed on the inner ring of the second steel pipe upper end or the interior of the first steel pipe lower end
Snare is connected to the outer ring of the second steel pipe upper end.
Further, it is provided with multiple upper gussets between upper plate and the first steel pipe.
