Description
Technical field
The present invention relates to a kind of steel anchor beam section preparation method, more specifically, one kind is used for steel structure bridge
Steel anchor beam section preparation method.
Background technology
Girder or the bridge that arch rib material is steel, are commonly referred to as steel bridge.Bridge pier, bridge tower, floorings etc.
Other materials can be then steel, concrete etc..Steel structure bridge mainly include highway steel structure bridge and
The major class of railway steel structure bridge two, currently, transport development China as the infrastructure given priority to,
Development is very rapid, also promotes the development of science of bridge building.Particularly in recent years, steel structure bridge due to
Have many advantages and widely used by engineering circles.In country《Mid-long term railway network plan》In it is bright
Really propose, to the year two thousand twenty, china railway operation mileage is up to 100,000 km, and main busy trunk lines are real
Now separate lines for passenger and freight, the km of planning construction new line about 1.6 ten thousand, planning is that the km of two wires 1.3 ten thousand is built in wired increasing,
Great opportunity is provided for the construction of railroad bridge, also will bring bigger for China railways bridge steel plate
Development.In bridge steel development from now on, the high intensity, solderable of science of bridge building development need is complied with
Property, the good high performance bridge steel of anti-breaking property, fatigability, weatherability will be the main of bridge steel development
Direction.
At present, the development of Bridges in Our Country steel is slower, and it is high that current bridge steel also rests on traditional low-alloy
In strength steel level, bridge main is with the kind of steel：14MnNbQ, 16Mnq, SET355,
SM490C and novel weathering resistant bridge steel etc..The main member of bridge steel structure include steel plate, section bar,
High-strength bolt, cast steel etc., and the full weldering built up by these or bolted and welded structure.These steel grades are all deposited
In the weakness that some can not overcome, such as thickness of slab effect is serious, welding performance is bad, low strength, and
And do not possess good weather resistance.Meanwhile, steel structural bridge beam is complicated, there is certain manufacture
Difficulty, partial component only has large-scale steel mill, shipyard to build, between bridge member manufacturing enterprise
In the presence of very big technological gap.
The content of the invention
The invention provides a kind of steel anchor beam section preparation method, this method has preparation easy, quick,
The advantageous effects of Stability Analysis of Structures and good weatherability.
In order to realize the purpose of the application, the technical scheme that the application is used is：
A kind of steel anchor beam section preparation method, comprises the following steps：
Step one

First dividing plate (N5a) assembly line, second partition (N6a) assembly line, web (N1) assembly line,
Case is put more energy into (N5, N6) assembly line outside；
Step 2
First dividing plate (N5a) and second partition (N6a) is installed to line, spot welding is fixed, second every
Plate (N6a) and web (N1) full penetration, each reserved 3mm in width both sides welding
Amount of contraction, width presses center line alignment installation；
Step 3
By line install web (N1), spot welding is fixed, web (N1) should pull in advance center line,
Suspension cable center line, web alignment line, bearing plate (bearing plate N7), (NJ1) assembly line of putting more energy into,
Case is put more energy into (N5, N6) assembly line, top plate (N4) assembly line outside, with the anchor pad of web during line
On the basis of plate machined surface, the web alignment lines of two coxostermums aligns peace with the web alignment line on bottom plate
Dress, it is ensured that the polishing of anchor plate and two coxostermums is held out against；
Weld seam along web and bottom plate adds temporary support, is arranged a pair every 400mm, Ran Houjin
Row diaphragm plate and web, the welding of bottom plate, and web and base plate interior angle welding, welding grooving
Type, after taking out temporary support after weld seam cooling, welding sequence is：First the facade of welding N6a dividing plates two melts
Saturating weld seam, then the trihedral angle weld seam of N5a dividing plates is welded, finally weld the angle of web and bottom plate box house
Weld seam, is strictly detected to weld seam, smooth to all arc craters and the defect reconditioning transfinited；
Step 4
Top plate N4 is installed to line, each system line, hookup wire, rod member home record width, height gauge is checked
It is very little, special survey port sizes, tack welding after passed examination, by welding condition carry out top plate with
The T-shaped groove welding of web, member bar turning completes web and bottom plate penetration weld；
Step 5
Bearing plate bearing plate N7 is installed to line and the unit piece that NJ7 is prefabricated into of putting more energy into, put more energy into NJ1,
Because insert space is narrow and small, and bearing plate N7 requires penetration with web, therefore, takes from the inside to the outside
Room for manoeuvre welded and installed, first group weldering is close to top plate side bearing plate N7 unit pieces, then organizes weldering and put more energy into NJ1,
Rigidity support should be increased before welding bearing plate bearing plate N7 with anti-deformation, bearing plate N7 is adopted with web
With band steel sleeve single face welding and double face shaping welding procedure, groove is faced outwardly；
Step 6
It is soldered after NJ1, finally group weldering outside bearing plate N7 unit pieces notice that polishing is held out against during spelling
In face of neat；
Step 7
To the N3, N5, N6, longitudinal spacing plate N9 and anchor plate N8 of being put more energy into outside line erecting and welding case, note
The direction on meaning N8 inclined-planes,
Weld seam detection, rod member correction, lifting is flat to hole Ni Zhifu drill mould bases after physical dimension detection inspection declaration is qualified
Platform, corrects each position line of rod member, requires to coordinate using steel band according to main longitudinal grider drill jig frame drilling construction figure
Carry out positioning and fine positioning at the beginning of rod member.Positioning uses locating template by rod member top flange, bottom wing after finishing
Edge and web positioning hole Ni Zhifu drill go out.Drill jig frame only completes the drilling of rod member positioning hole group, in operating process
Steel band must be used strictly to control the positioning spacing of rod member front and rear gaps group, make error<1.0mm；
Using bore template, pairing rod member positioning hole carries out hole Ni Zhifu drill hole successively；
Hole group's burr is removed, rod member inspection declaration；The technique connection of bottom plate termination is cut off by line, to cutting after cutting
Position burr etc. is cut to be polished；Carry out mark, mark etc., including numbering, direction, overall inspection declaration.
