Description
Technical field
The invention belongs to steel construction facility technology fields, more particularly to a kind of steel structural bridge beam joint device.
Background technique
As technology is showing improvement or progress day by day in all respects for the rapid advances and steel structure bridge of society, steel structure bridge by
It is widely applied.With China's expanding economy, to the further demand in living space, steel structure bridge has greatly development empty
Between.
The development of China's steel and iron industry provides solid material base for the development of steel structure bridge.China has had more
The bridge factory of family's profession, produces the steel structure member of profession, there is large quantities of technologies and all mature Construction of Steel Structure unit of management,
Application all for steel structure bridge in China provides good condition.The external recent technology of China's reference, to steel structure bridge
Etching problem there has also been more effective solution modes；Rural population cityward is concentrated, and is proposed to the effective use in space
Further requirement also promotes the application of city steel structure bridge；It is achieved acquired by 20 year traffic fields after 20th century in China
Inspiration under, conceive 21 century more massive development.Realize same three line (same to river-Sanya) of one of backbone of north and south perforation
On will build Bohai Haixia engineering, entrance of Changjiang River and get over river engineering, Hangzhou Wan sea-crossing engineering, the mouth of the Zhujiang River In Lingding Yang Area engineering；Zhoushan Islands
Also in the blue print be connected by 6 island Ge Kua sciences of bridge building with continent；Many cities along the river all will be more by building
Seat bridge cross Yangtse River forms urban ring road, to solve the problems, such as increasingly congested traffic.The implementation of all these blue prints, especially
The construction of super long-span bridge will provide great scope of land for steel structure bridge.
With the economic development of our countries, this industry of steel begins to ramp up trend, and the yield of steel increases day by day, because
The application of this steel construction is also gradually come extensively, and high-strength bolt manufacturing firm just considers when carrying out analysis production to steel construction
Steel construction feature itself is arrived, not fire resistance, it is being passed through in analysis one element structure form, connection type, material etc.
Important evidence when being studied after high temperature and stress, people are exactly high-strength with a kind of most connection types in steel construction
Degree is bolted, it is understood that in a complete firm frame structure, tie point be it is most important, according to inappropriate company
Connect mode or jerry reduction tie point etc. all can cause to seriously affect to engineering, safety of workers, construction speed etc.,
Workpeople will use the scaffold that we often say when carrying out indoor and outdoor decoration or when small high-rise building is built, scaffold is
Built with steel pipe one by one, it is desirable to build one firm, bearing capacity is high scaffold just use connector, one is complete
Whole scaffold is to need multiple tie points, these tie points are must to fix and must not reduce fastener for installing, to keep away
Exempt from scaffold to collapse because node loosens, equally ensures that the safety coefficient of construction personnel, this just illustrates a steel construction
Connection type affects entire steel construction completely, and high-strength bolt manufacturing firm is in production high-strength stainless steel bolt connection piece
When, it is necessary to consider performance under bolt at high temperature, this namely important evidence when studying Fire-Resistance of Steel Structures.
Nowadays, the shortcomings that being bolted mainly has the following: 1, component requirement on machining accuracy is high, and rubbing surface needs
Special protection increases cost；2, the stress of each bolt of Bolt is unable to reach that substantially uniformity is consistent, and part bolt may shift to an earlier date
Fatigue fracture, to cause damages；3, it is mainly high-strength bolt, just has quality to ask due to the loss of tensile stress, or when construction
Topic, will lead to the rubbing surface changing of the relative positions, changes the stress of structure, there is the danger of unstability；4, it is bolted necessary aperture, is reduced
The intensity in section also will cause stress concentration；5, bolt itself unstable quality always has some quality fluctuations, some spiral shells
Bolt is exactly defect ware when dispatching from the factory, if do not found, is also used in structure, like that will be dangerous.
