Description
One, technical field:
The present invention relates to a kind of arch hexagon steel box-girder preparation method, belong to structural steelwork construction field.
Two, background technology:
Little Miao Zi township, Qingshuihe County, Huhehaote City bridge, bridge steel structure view is shaped to butterfly, and bridge is complete
Long 100m, width 28m, bridge floor both sides monolithic arch rib signifies the double-vane of rapid development, by main arch and two side arches
It is formed by connecting by I-shaped strut.The arch of main arch rib is parabola, and its cross section uses hexagon steel case
Cross section, a width of 1.4m, high 1.2m, thickness of slab 16mm, main arch sagitta 16.63m, main arch span 60m.Side is encircleed
For square-section, high 0.4m, wide 0.3m, thickness of slab 12mm, side arch has a hyperboloid spatial modelling, main arch with
Angle 9.9 ° between the arch of side, main arch is linked into an integrated entity by strut with side arch.When the main arch of butterfly arch bridge makes,
Because main arch is the parabolic shape that hexagon steel box-girder is made, in the prior art, steel box-girder mostly is quadrangle
Steel box-girder, does not the most make arch hexagon steel box-girder mature technology.
Three, summary of the invention:
The present invention is directed to prior art not enough, propose a kind of a kind of arch six limit simple to operate, easy to use
Shape steel box-girder preparation method.
The technical problem to be solved in the present invention is to put forward a kind of arch hexagon steel box-girder preparation method of arch, first
Carrying out making the mold used by arch hexagon steel box-girder, described mold includes base and template, and its feature exists
In: described base includes bottom girder, joist, connecting plate, strut, and described bottom girder is added by 2 No. 56 I-steel
Work forms, and level interval 300mm between 2 No. 56 I-steel, along bottom girder length side, every 500mm is 2
Being connected with connecting plate in the middle of individual No. 56 I-steel, described joist uses 2 No. 32 I-steel to add
Work forms, and joist is placed on the centre position of plane on bottom girder and links into an integrated entity with bottom girder.Described template is adopted
Processing with 16mm steel plate, arc is processed in a side of template, its radian and arch hexagon steel
The radian of the bottom wing listrium of box beam is identical, and template is placed on joist plane and links into an integrated entity with joist, edge
Joist length direction, template is reinforced by every 500mm at 2 No. 32 I-steel both sides struts.Because of arch
Shape hexagon steel box-girder span is 60m, during described internal model making, first releases arch hexagon steel case on platform
The arc curve of the bottom wing listrium of beam, is fabricated to some sections by described base, puts inside arc curve,
And with connecting plate, each section of base is linked into an integrated entity, the template processed is fixed on base completes tire subsequently
Tool makes.During construction, first the bottom wing listrium of the arch hexagon steel box-girder processed is fixed in template,
Bottom wing listrium is adjacent to the arcuate flanks of template and keeps vertical, and ensures in bottom wing listrium center line and template
Planar registration, releases the rigging position line of diaphragm plate subsequently on bottom wing listrium and diaphragm plate installation is put in place,
The most following two blocks of webs are installed and put in place, and along its length, every 500mm bearing is fixed,
Last above two blocks of webs and top flange plate installations again puts in place, completes the assembler of arch hexagon steel box-girder
Make.
The useful good effect of the present invention: the present invention is easy to operate, can effectively ensure that arch hexagon steel box-girder
Assembly precision and quality, and improve work efficiency, in construction, mold material used should be in other engineering project
In be continuing with, meet green construction technology, reduce construction cost, the effect of environmental protection.

Five, detailed description of the invention
Embodiment one: see Fig. 1, Fig. 2, Fig. 3, the present invention relates to a kind of arch hexagon steel box-girder and makes
Method, first carries out making the mold used by arch hexagon steel box-girder, and described mold includes base 1 and mould
Plate 5, it is characterised in that: described base 1 includes bottom girder 2, joist 4, connecting plate 3, strut 6, the described end
Beam 2 is processed by 2 No. 56 I-steel, and level interval 300mm between 2 No. 56 I-steel, the end of along
Beam 2 length side, every 500mm is connected with connecting plate 3 in the middle of 2 No. 56 I-steel, described
