Description
Technical field：
The present invention relates to big steel building, more particularly under vibrations load situation Large Steel tubing string docking attachment means and
Method.
Background technology：
Current many industrial factory buildings, civil buildings are all used as agent structure using steel construction.Some of industry or
The agent structure of civilian vestibule is when from supporting member, it is considered to which component all directions stress equalization often uses large-scale steel pipe
It is used as support column.By existing process processing method, the steel pipe interface of large-scale steel pipe support column is generally handled using docking mode, and
The large-scale steel pipe support column interface of this docking mode processing generally there are following defect：
1：The steel pipe interface position weld seam welding quality of Large Steel tubing string requires very strict, weld bond scarfing cinder, polishing work
Amount is very big, and labor strength is high；
2：Steel pipe column interface position weldquality is often difficult to reach inspection of quality requirement；
3：In the case of Large Steel tubing string interface position multiple-pass weld repeatedly welding, steel pipe interface position both sides 50mm scopes
Interior steel pipe column mother metal institutional framework changes, crystal grain roughening, produces welding heat affected line.Under vibrations load action,
Weld bond position steel pipe column mother metal cracking is easily caused, it is unfavorable to structure stress；
4：Under mechanical shock load action, the steel pipe interface docking location of steel pipe column is easy to occur weld bond cracking or welded
Mouth position steel pipe column mother metal CRACKING ACCIDENT, scaffold building workload is big in the case of work high above the ground when reprocessing, and reprocesses construction extremely
Inconvenience, reprocesses construction welding quality and is difficult to reach acceptance specification requirement, easily cause and repeatedly do over again, even result in body supports post office
Portion or integral replacing, cause great engineering safety hidden danger.
The content of the invention：
In order to solve the above technical problems, it is an object of the invention to provide large-scale steel pipe under a kind of novel vibration loading condition
Post docks attachment means and method, the butt welding of large-scale steel pipe support column is reached safety, economy, service-strong requirement.
Large Steel tubing string docking attachment means are pacified inside Large Steel tubing string interface under present invention vibrations load situation
Fill waveform bushing pipe, it is characterised in that：Waveform bushing pipe is installed inside steel pipe column interface, waveform bushing pipe two ends waveform is welded
On the inside of two steel pipe columns, steel pipe column interface on the outside of waveform bushing pipe with welding together.
Waveform bushing pipe is characterised by that thickness is waveform bushing pipe two ends wave peak width chi in steel pipe column thickness t or t+2mm, pipe
Very little is 600 --- 900mm, two ends wave base width dimensions are 300 --- 600mm, crest, wave base radius are 50 --- 100mm,
Form one of difference of height 100 --- 200mm waves.
Connection method of the present invention is carried out according to the following steps：
A:Blanking, mouth of pipe polishing are segmented by design requirement, stayed behind mouth of pipe mating interface gap, in system during steel pipe column production
Make scene or job site ground to assemble the docking of steel pipe column main body, the interim tack-weld of interface position, tack weld thickness >=
3mm, length ﹥ 40mm, 300~600mm of spacing.
B:After in place, the every dimensional check of steel pipe column docking is errorless, you can install in place with waveform bushing pipe in managing.In pipe
Waveform bushing pipe is installed uses interim tack-weld, tack weld thickness >=3mm, length ﹥ 40mm, 300~600mm of spacing in place.
C:After steel pipe column is completed, external interface position butt welding, the butt weld of external interface position are carried out first
Carry out managing interior waveform bushing pipe and supervisor's waveform welding procedure again after welding quality passed examination, it is interim fixed during welding procedure
Site welding line must be abraded using abrasive machine.
The present invention compared with prior art, under equal execution conditions, due to the installation of waveform bushing pipe in pipe, makes in pipe
Waveform bushing pipe becomes the interior lining panel of the docking mouth of pipe, is again enhanced pipe joint position intensity.While bushing pipe waveform weld seam
It it also avoid welding the heat affecting to pipeline quality of parent material；Avoid the generation of welding heat affected line, it is to avoid steel pipe column docking
Weld bond polishing recondition, reduces welding procedure workload；It ensure that welding quality；Reduce labor strength；Avoid
The influence that weld bond ftractures to construction quality, it is ensured that construction quality；Weld bond position steel pipe is female after the completion of avoiding project installation
Material CRACKING ACCIDENT, eliminates when reprocessing scaffold building work in the case of work high above the ground, reprocesses construction welding quality and be difficult to reach and test
Receive code requirement predicament；Avoid engineering safety hidden danger.Also reduce Construction Cost simultaneously.
Brief description of the drawings：
Fig. 1 is that the docking connection construction process that generally uses of steel pipe mating interface processing of original large-scale steel pipe support column is shown
It is intended to；
Fig. 2 is Large Steel tubing string docking attachment means and method docking connection construction process under present invention vibrations load situation
Schematic diagram.
Embodiment：
It is visible referring to the drawings 1, accompanying drawing 2, Large Steel tubing string docking attachment means and method under present invention vibrations load situation
It is different from the building form of the steel pipe mating interface handling process of original steel pipe support post.
Original large-scale steel pipe mating interface position is in the case of multiple-pass weld repeatedly welding, and construction quality is difficult to be protected
Card, while steel pipe mother metal institutional framework changes in the range of steel pipe interface position both sides 50mm, crystal grain is roughened, in vibrations
Under load action, weld bond position steel pipe mother metal cracking is easily caused, it is unfavorable to structure stress.
The present invention installs waveform bushing pipe 2 inside the interface of Large Steel tubing string 1, and the two ends waveform 3 of waveform bushing pipe 2 is welded
In the inner side of two steel pipe columns 1, the interface of steel pipe column 1 is formd one new large-scale with welding together on the outside of waveform bushing pipe 2
Mouth of pipe docking mode.Under equal execution conditions, due to the installation of waveform bushing pipe 2 in pipe, obtain pipe joint position intensity
To strengthen；Bushing pipe waveform weld seam it also avoid welding the heat affecting to pipeline quality of parent material simultaneously；Due to waveform bushing pipe 2 in pipe
Weld substrate effect, it is ensured that welding quality, reduce labor strength；Avoid shadow of the weld bond cracking to construction quality
Ring, it is ensured that engineering total quality；Reduce Construction Cost.
