Description
Technical field
The present invention relates to a kind of Prefabricated composite structural column and preparation method thereof based on Ripple Sternum.
Background technique
Assembled architecture is widelyd popularize, building waste and dust pollution are reduced, shortens construction duration, promotes engineering matter
Amount.It is required that " formulating assembled architecture design, construction and acceptance specification.Component component standards are improved, realize building subassembly component
The factorial production.Encourage building enterprise's fabricated construction, assembled in situ.Building national grade assembled architecture production base.It increases
Policy support dynamics strives that, in 10 years or so time, the ratio for making assembled architecture account for new building reaches 30% ".It is actively steady
Appropriate popularization steel building.
Such fashioned iron can replace traditional profile steel concrete column, reinforced concrete with the component form that concrete is effectively combined
Earth pillar or single steel structure column form structural system as vertical Force transmission parts.
The component form that such fashioned iron and concrete are effectively combined makes column cross-section size and regular reinforcement because bearing capacity is higher
Concrete column compares, and the usable floor area of indoor increase by 3%~5% can be made for similarly building.This rod structure reduces steel
The bare area of structure, to reduce anti-corrosion, fireproof material.Production and processing, transport, lifting agree with country well
The policy of assembled architecture is widelyd popularize, energy saving, reduction pollution that can be practical shorten the construction period, promote construction quality.
Fashioned iron efficiently combines two kinds of material properties with the component form that concrete is effectively combined, with lesser sectional dimension
Reach higher load-carrying efficiency；Complicated reinforcing bar binding, the work of template support in process are simplified, it can be more preferable
Control product quality；And it is difficult to solve connecting node constructional difficulties, quality in common prefabricated reinforced concrete column construction
The problem of control.Concrete in traditional concrete structure steel column is insecure in conjunction with steel column, and the concrete of solidification is easy and steel
The surface of column separates, to influence the bearing capacity of concrete structure steel column.

2/3, reduce for anticorrosion of steel structure and fireproof processing area.Due to being fill concrete 9, do not increasing column outsourcing
In the case where size, the bearing capacity of H profile steel column greatly improved, solve the problems, such as that H profile steel column stability is poor.
A kind of suspension column of Prefabricated composite structural column based on Ripple Sternum of the invention and basis are using hinged, rigid
It connects in succession.If the Prefabricated composite structural column needs based on Ripple Sternum are connect with other components, or are needed
The Prefabricated composite structural column that upper and lower two are based on Ripple Sternum is linked together, then 1 edge of a wing of Ripple Sternum with
Certain space is reserved when the upper lower prop stitching section position of the steel column of fill concrete is prefabricated in the factory at 2 enclosing of web not pour
Concrete is infused, upper lower prop is welded to connect or is bolted by fashioned iron, at the construction field (site) upper lower prop connecting portion after the completion of lifting
It is poured concrete again, concrete uses microdilatancy pea gravel concreten.Weldering can be used in the upper lower prop joint connection in site of profile steel concrete column
It connects or the strong ties such as high-strength bolt, the construction reserved space microdilatancy pea gravel concreten second pouring between upper lower prop, connection
Reliably, construction is simple.Component can be used in the structural system of reinforced beam or girder with rolled steel section en cased in concrete structural system in,
It can be used in steel beam structure system, bean column node is welded or is bolted and can be used, in-site installation after factory process, application
Range is very extensive.Industrial standardization production degree of the present invention is high, it is easy to accomplish design, Systemizing production and construction in concrete project improve dress
With formula building industrialization level.
Correspondingly with a kind of Prefabricated composite structural column based on Ripple Sternum of the invention, the present invention also provides one
The method for kind making 1 Prefabricated composite structural column of Ripple Sternum, for making above-mentioned technical proposal or its is any preferred

1) it is welded to connect reinforcing bar 6 in the first channel space 4 of Ripple Sternum 1 and the second channel space 5, respectively connects
It connects reinforcing bar 6 to arrange along 2 length direction of web, the both ends of connection reinforcing bar 6 are respectively welded on two wing plates 3；
2) make the opening up of the first channel space 4 of Ripple Sternum 1, and be poured and mix in the first channel space 4
Solidifying soil 9；
3) after being solidified to the concrete 9 in the first channel space 4, Ripple Sternum 1 is overturn and makes the second flute profile
Space 5 upward, and is poured concrete 9 in the second channel space 5；
4) 1 Prefabricated composite of Ripple Sternum that will be made after being solidified to the concrete 9 in the second channel space 5
Structural column is temporary.
A kind of method making 1 Prefabricated composite structural column of Ripple Sternum of the invention has of the invention one certainly
The beneficial effect of Prefabricated composite structural column of the kind based on Ripple Sternum, details are not described herein again.Make the corrugated web H
The method of 1 Prefabricated composite structural column of fashioned iron is simple and convenient, by the horizontal traverse of H profile steel, that is, pourable concrete 9, is not necessarily to template, H
Steel section member can be completed whole concrete 9 through 1 overturning and be poured.It is reduced without assembling reinforcement and support template convenient for construction
Cost.
Preferably, in the step 3), to the condensation of concrete 9 in the first channel space 4 to the 70% of amount intensity
Ripple Sternum 1 is overturn and makes the second channel space 5 upward after above.In this way, concrete 9 can be protected with H profile steel
