Description
Technical field
The present invention relates to a kind of steel anchor beam segment preparation methods, more specifically, a kind of steel anchor beam section for steel structure bridge
Section preparation method.
Background technique
Girder or arch rib material are the bridge of steel, are commonly referred to as steel bridge.The other materials such as bridge pier, bridge tower, floorings then may be used
For steel, concrete etc..Steel structure bridge mainly includes highway steel structure bridge and railway steel structure bridge two major classes, currently,
In China as the infrastructure given priority to, development is very rapid, also promotes the development of science of bridge building for transport development.Especially
It is that in recent years, steel structure bridge is widely used due to having many advantages by engineering circles.In national Mid-term and Long-term Plan of the Railway Network
In clearly propose, arrive the year two thousand twenty, china railway operation mileage is up to 100,000 km, and main busy trunk lines realization separates lines for passenger and freight, and advises
Construction about 1.6 ten thousand km of new line is drawn, planning is that 1.3 ten thousand km of two wires is built in wired increasing, provides great machine for the construction of railroad bridge
It meets, bigger development will be also brought for China railways bridge steel plate.In bridge steel development from now on, science of bridge building development is complied with
The high intensity that needs, solderability, anti-breaking property, fatigability, the good high performance bridge steel of weatherability by be bridge steel development master
Want direction.
Currently, the development of Bridges in Our Country steel is slower, it is horizontal also to rest on traditional Hi-Stren steel for bridge steel at present
On, bridge mainly uses the kind of steel are as follows: 14MnNbQ, 16Mnq, SET355, SM490C and novel weathering resistant bridge steel etc..Bridge
The main member of steel construction includes steel plate, profile, high-strength bolt, cast steel etc., and the full weldering or bolt weldering built up by these are tied
Structure.All there are some weakness that can not be overcome in these steel grades, as plate thickness effect is serious, welding performance is bad, low strength, and
Do not have good weather resistance.Meanwhile steel structural bridge beam is complicated, has certain manufacture difficulty, partial component only has
Large-scale steel mill, shipyard can be built, and there is very big technological gap between bridge member manufacturing enterprise.
Summary of the invention
The present invention provides a kind of steel anchor beam segment preparation method, this method has that preparation is easy, quickly, stable structure and
The advantageous effects of good weatherability.
In order to realize the purpose of the application, the application the technical solution adopted is that:
A kind of steel anchor beam segment preparation method, comprising the following steps:
Step 1
Center line, web alignment line, first partition (N5a) are drawn in horizontal moulding bed positioning, the polishing of bonding wire region on bottom plate (N2)
It puts more energy into outside assembly line, second partition (N6a) assembly line, web (N1) assembly line, case (N5, N6) assembly line；
Step 2
To line installation first partition (N5a) and second partition (N6a), spot welding is fixed, second partition (N6a) and web (N1)
Full penetration, the welding contracted quantity of each reserved 3mm in width direction both sides, width direction press center line alignment installation；
Step 3

When scribing line on the basis of the anchor plate machined surface of web, the web alignment line of two coxostermums with the web alignment line pair on bottom plate
Neat installation, 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, arranges a pair every 400mm, then carries out diaphragm plate and abdomen
The fillet weld of plate, the welding of bottom plate and web and base plate interior, is welded into groove profile, takes out temporary support after weld seam is cooling,
Welding sequence are as follows: first weld two facade melt-through weld of N6a partition, then weld the trihedral angle weld seam of N5a partition, finally weld web with
The fillet weld of bottom plate box house carries out strict inspection to weld seam, smooth to all arc craters and the defect reconditioning transfinited；
Step 4
Top plate N4 is installed to line, checks each system line, hookup wire, rod piece home record width, height dimension, special survey port
Size, tack welding after passed examination are carried out the T-type groove welding of top plate and web by welding condition, and member bar turning completes abdomen
Plate and bottom plate penetration weld；
Step 5
To line installation bearing plate bearing plate N7 with the unit piece that NJ7 is prefabricated into of putting more energy into, put more energy into NJ1, since insert space is narrow
It is small, and bearing plate N7 and web require penetration, therefore, take the welding installation that regresses from the inside to the outside, first group is welded holds close to top plate side
Pressing plate N7 unit piece, then organize 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 and web use band steel sleeve single face welding and double face shaping welding procedure, and groove faces outwardly；
Step 6
After being soldered NJ1, finally group weldering outside bearing plate N7 unit piece, when spelling, notices that polishing is held out against in face of neat；
Step 7
To N3, the N5 of putting more energy into outside line erecting and welding case, N6, longitudinal spacing plate N9 and anchor plate N8 pay attention to the direction on the inclined-plane N8,
Weld seam detection, rod piece correction, lifting corrects rod piece to hole Ni Zhifu drill mould bases platform after geometric dimension detects inspection declaration qualification
Each position line carries out rod piece just positioning and fine positioning using steel band cooperation according to the requirement of main longitudinal grider drill jig frame drilling construction figure.It is fixed
Rod piece top flange, lower flange and web location hole Ni Zhifu drill are gone out using locating template after position.It is fixed that drill jig frame only completes rod piece
The drilling of position Kong Qun must use the positioning spacing of steel band strict control rod piece front and rear gaps group in operating process, make error <
1.0mm；
Using bore template, pairing rod piece location hole successively carries out hole Ni Zhifu drill hole；
Hole group's burr removal, rod piece inspection declaration；The connection of bottom plate end technique is cut off by line, to cutting part burr etc. after cutting
It polishes；It marks, identify, including number, direction, whole inspection declaration.
