Detailed description of the invention
The present invention is described in further detail by 1 to Fig. 7 with embodiment below in conjunction with the accompanying drawings:
Embodiment 1
Wavelike steel webplate steel construction continuous box girder, as shown in Figures 1 to 6, including two pieces of Wavelike steel webplates 2,
Top steel plate 1, bottom steel plate 3, connect end, and described Wavelike steel webplate 2 is arranged on top steel plate 1 and the end
Between portion's steel plate 3, top steel plate 1 and Wavelike steel webplate 2 by being welded to connect, Wavelike steel webplate 2 and the end
Portion's steel plate 3, by being welded to connect, by connecting end connection between single girder construction, forms beam structure.
Top steel plate, bottom steel surface roughness are 70-350 μm.Increase top steel plate 1, bottom steel plate
3 surface roughnesses, high roughness can substantially increase the adhesive force of coating.
Wavelike steel webplate is the continuous ladder twists and turns steel plate of band changeover portion and circular arc-shaped corner, and changeover portion is positioned at straight line
Section and circular arc-shaped corner between, circular arc-shaped corner radius is r, the radius of changeover portion be R, R be gradual change radius, R
For ∞ r.Changeover portion 22 is connected with straightway 23 one end, radius be R be to tend to infinity；Changeover portion 22
Be connected one end with circular arc-shaped corner 21, radius be R be to tend to equal to r, therefore, straightway 23 to circular arc turn
Angle 21, the radius R of changeover portion 22 is for be gradually decrease to equal to r from infinity, so that straightway 23
With circular arc-shaped corner 21 more smooth transition, reduce stress and concentrate.The waveform of web by straightway, changeover portion,
Arc section three part forms, and wherein changeover portion can effectively connect straightway and circular arc-shaped corner, solves straight line
The problem that when section is directly connected to arc section, stress is concentrated, is suitable for industrial mass manufacture, mould and manufacture
Cost is relatively low.
Wavelike steel webplate is L along the point of contact wire length in wave height directionAB, along the point of contact wire length of wavelength direction
For LBC, LAB≥LBC.Wavelike steel webplate 2 is equal or slightly larger than along ripple along the point of contact wire length in wave height direction
The point of contact wire length of length direction, i.e. LAB≥LBCDesign make the shearing strength of corrugated sheet steel and steel using amount reach
To good cost performance, if wavelength direction is long, i.e. LBC≥LABThen shear behavior substantially reduces, and ripple
Length direction is too short, then steel using amount significantly increases.Therefore, L is usedAB≥LBCDesign, can either ensure
Shearing strength, can reduce again rolled steel dosage as far as possible.
Connecting end compressive region is plug in construction, and tensile region is the connected devices of band cavity.Being connected with cavity
Device is for as it is shown in fig. 7, plug 24 is provided with barb, and jack 25 is concave.
Plug in construction is that connection end one end of box beam is provided with plug 24, and the other end is provided with jack 25, adjacent letter
Prop up and be connected with jack 25 by plug 24 between box beam.The plug-in type bearing structure of compressive region can not only
Make stable connection, and possess shrink space when variations in temperature.While the stable connection of tensile region, it is empty
The phenomenon of expanding with heat and contract with cold arranged when can resist beam body variations in temperature in chamber.
Plug 24 is cylinder, and jack 25 is for coordinate hollow cannula with plug 24.
The thickness of top steel plate 1 is more than or less than the thickness of bottom steel plate 3.Because compressive region need to consider flexing,
Tensile region then need not consider flexing, so traditional tensile region is identical with the steel using amount of compressive region or area of section,
Making tensile region part there is function to have more than needed phenomenon, be not science and uneconomic, compressive region steel using amount suitably increases
Greatly, the beneficially pressurized of component, the function of tension part gives full play to, and reaches higher cost performance.Top
When the thickness of steel plate 1 is more than the thickness of bottom steel plate 3, it is common box beam, and top steel plate 1 bears pressure.
Top steel plate 1, bottom steel plate 3 are arch along Wavelike steel webplate 2 wavelength direction.Top steel plate 1,
Bottom steel plate 3 is arch, and beneficially member stress offsets component downwarp in the case of carrying, improves box beam
Overall construction intensity.
Embodiment 2
Such as Fig. 1 to Fig. 5, shown in 7, the present embodiment is with the difference of embodiment 1: single girder construction it
Between connect by steel strand cable 5, form beam structure.Connecting end compressive region is plug in construction, and plug-in type is tied
Structure is that connection end one end of box beam is provided with plug 24, and the other end is provided with jack 25, logical between adjacent simple supported box beam
Cross plug 24 to be connected with jack 25.Coordinated with jack 25 by plug 24, the plug-in type of compressive region
Bearing structure can not only make stable connection, and possesses shrink space when variations in temperature.Tensile region connects steady
While Ding, the phenomenon of expanding with heat and contract with cold arranged when can resist beam body variations in temperature of its cavity.
Plug 24 is provided with barb, and jack 25 is concave.The thickness of top steel plate 1 is less than bottom steel plate 3
Thickness.Now, bottom steel plate 3 is as pressure-bearing surface, and its main version is cantilever boxgirder.
Connection end is high-strength bolt, weldment.The present invention can also be by high-strength bolt by adjacent case
Beam links together, or by weldment by adjacent box beam Welding together.
In a word, the foregoing is only presently preferred embodiments of the present invention, all made according to scope of the present invention patent
Impartial change with modify, all should belong to the covering scope of patent of the present invention.
