Description
Technical field
The present invention relates to bridge welding technical fields, and in particular to a kind of steel bridge crossings on different level welding line structure and its construction party
Method.
Background technique
In steel structure bridge design, the wing plate and web of steel member often connect in same section butt welding, wing plate butt welding
Fillet weld between seam, web butt weld and web and wing plate forms crossings on different level, is intersected in a bit on interface.It is a plurality of
The weld seam overlapping that crosses can cause welding residual stress cumulative and welding defect, need using reasonable construction arrangement and welding procedure
Method improves component butt weld stress safety.Steel member is just being answered caused by bearing most of moment of flexure in Moment lower wing plate
Power, web are primarily subjected to shear stress.Combination member stress characteristic, frequently with weld seam arrangement be: wing plate butt weld connect
It is continuous;Welding hole was reserved at web butt weld both ends, was convenient for the welding of wing plate weld seam.Reserved weldering in traditional web butt weld both ends
Hole is crossed after the completion of welding and fills sealing material at welding hole, the disadvantage is that, web holes edge is vertical with wing plate surface, and component is cut
Face mutation causes flange plate stress at this to be concentrated, and there are fatigue rupture risks;And cross welding hole filling sealing material often because aging,
Drying shrinkage causes to crack, and loses sealing function, needs to be regularly maintained.Considering should stress safe good airproof performance, maintenance work again
It measures small, then needs a kind of novel solid to intersect weld configuration, to solve the above problem brought by traditional intersection weld configuration.
Summary of the invention
In place of overcoming above-mentioned the deficiencies in the prior art, and a kind of improvement fatigue strength is provided, is mentioned
The steel bridge crossings on different level welding line structure and its construction method of high sealing structure and durability.It solves conventional stereo and intersects weldering
The abrupt change of cross-section of seam construction, antifatigue effect ability is weak, spends the problem of welding hole plugging material Cracking Failure.
To achieve the goals above, the present invention provides a kind of steel bridge crossings on different level welding line structures, including are mutually perpendicular to weld
The web and wing plate connect, it is characterised in that: the bottom surface of the first wing plate of the side and wing plate of the first web of the web
Longitudinal measure forms the first steel construction unit piece, the bottom of the second wing plate of the side and wing plate of the second web of the web
The first aperture has been respectively cut in the lateral margin of face longitudinal measure the second steel construction unit piece of formation, first web and the second web
With the second aperture, the first steel construction unit piece and the second steel construction unit piece butt welding, first aperture and the second aperture
Docking formed welding hole and crossed welding hole forms opening at the abutment joint of the first wing plate and the second wing plate, described to cross web at welding hole
One or both sides be covered with stiffening plate, the outer rim of the stiffening plate is continuously welded with web and wing plate respectively.
Based on the above technical solution, first aperture and the second aperture is semicircular arc, the first aperture and
The upper end of second aperture is tangent with the first wing plate and the second wing plate respectively, the first aperture and the second aperture lower end edge semicircular arc end
The tangential direction of point extends respectively to the end of the first web and the second web, and the welding hole of crossing is nose circle shape.
Based on the above technical solution, the equal arc-shaped transition in the two sides of the stiffening plate and the junction on bottom edge.
Based on the above technical solution, the abutment joint bottom surface of first wing plate and the second wing plate, which is welded with, passes across
The liner of the strip of welding hole.
Meanwhile also providing a kind of construction method of steel bridge crossings on different level welding line structure, which is characterized in that including walking as follows
It is rapid:
1) after the first wing plate, the second wing plate, the first web, the second web blanking, by the end of the first web, the second web
Portion lateral margin is cut into the first aperture and the second aperture of semicircular arc, and the upper end of semicircular arc and wing plate are tangent, semicircular arc
Lower end edge semicircular arc endpoint tangential direction extends to the end of web;
2) the bottom surface longitudinal measure of the side of the first web and the first wing plate is formed into the first steel construction unit piece, by second
The bottom surface longitudinal measure of the side of web and the second wing plate forms the second steel construction unit piece, respectively by the first web and the second abdomen
The end polishing of the first aperture and the second aperture on plate is even suitable;
3) by the first steel construction unit piece and the second steel construction unit piece butt junction location, by the first web and the second web pair
It is integral to connect penetration weld, face of weld polishes, and the first aperture and the second aperture formed welding hole;
4) the first wing plate and the second wing plate butt weld are continuously welded;
5) web one side or two sides weld reinforcement plate at welding hole are being crossed, stiffening plate periphery and web and wing plate are continuous
Welding.
Based on the above technical solution, it in the step 4), is pasted in the first wing plate and the second wing plate abutment joint bottom surface
It pads after passing across welding hole, then the first wing plate and the second wing plate are continuously welded.
The present invention has the advantage that as follows: designed steel member web and wing plate connects in same section butt welding, seam
Locate web side to cut camber, the first steel construction unit piece and the second steel construction unit piece butt welding and formed welding hole,
It separates web butt weld with wing plate butt weld, weld seam collection is avoided to neutralize residual stress superposition.
Meanwhile the arc of seam crossing web side cutting is semicircular arc, the upper end of semicircular arc is tangent with wing plate, avoids
The abrupt change of cross-section drops stress concentration, reduces fatigue rupture risk.
Moreover, crossing web two sides or one side weld reinforcement plate at welding hole, stiffening plate outer rim and web and wing plate company
Continuous welding, forms closed structure, and stiffening plate meets force request.Not only aperture section is supplemented, but also forms permanent confined space,
Stress is reliable, and maintenance workload is small.It realizes the superposition of intersection weld residual stress, aperture section does not weaken, forms confined air
Between, be conducive to structure stress safety and durability.
