Abstract
A kind of compound concrete-filled tubular column -- steel beam joint, by outboard square-like large steel pipe, the small steel pipe of central circular, stiffener, girder steel and coagulation local soil type at, wherein outboard square-like large steel pipe and the small steel pipe of central circular be concentrically, it is connected between them using stiffener, stiffener is respectively using welded connecting between outboard square-like large steel pipe and the small steel pipe of central circular, two planes of symmetry of outboard square-like large steel pipe are connect with two girder steels respectively, connection type uses riveting method, compound concrete-filled tubular column -- this construction of beam can be used as the form of one of Architectural Structure Design structure node, gap and small steel duct space casting concrete between outboard square-like large steel pipe and the small steel pipe of central circular, after concrete setting reaches intensity, it is much larger compared to more common column-steel beam joint rigidity, it can be used for the earthquake territory of high anti-seismic requirement Domain frame structure.
Description
Technical field
The utility model relates to mainly fit to a kind of compound concrete-filled tubular column -- the steel beam joint in the realm of building construction
For industry and Civil structure design field.
Background technique
Concrete filled steel tube node of column and beam generallys use hollow steel pipe and is attached with girder steel or girder with rolled steel section en cased in concrete at present,
There is the form connecting using steel core concrete column with girder steel or girder with rolled steel section en cased in concrete, this properties of joint against bending is relatively good, but
It is in geological process horizontal force, in order to guarantee structure overall stiffness, the especially seismic region of high anti-seismic requirement, steel pipe
Column or concrete filled steel tube column section just can guarantee structure overall stiffness when needing to be designed into larger, design in this way certainly will make steel-pipe pile
The weight of itself is very big, increases difficulty to construction hoisting, on the one hand construction cost is caused to increase, while causing structural steel
Waste, on the other hand due to structure column section increase, would detract from building use space, it is both uneconomical, also do not utilize building to make
Use function.
Summary of the invention
The drawback in the design of earthquake territory common steel tube concrete column in order to solve high anti-seismic requirement, in economical rationality condition
Under, as much as possible to meet the needs of owner uses function to building, we have proposed a kind of compound concrete-filled tubular columns -- steel
Girder connection, by outboard square-like large steel pipe, the small steel pipe of central circular, stiffener, girder steel and coagulation local soil type at wherein outboard square-like is big
Steel pipe and the small steel pipe of central circular concentrically, between them are connected using stiffener, stiffener respectively with outboard square-like large steel pipe
Using being welded to connect between the small steel pipe of central circular, two planes of symmetry of outboard square-like large steel pipe are connect with two girder steels respectively,
Connection type uses riveting method, and this construction of compound concrete-filled tubular column-beam can be used as in Architectural Structure Design
A kind of form of structure node, gap and small steel duct space between outboard square-like large steel pipe and the small steel pipe of central circular are poured
Concrete is built, it is much larger compared to more common column-girder connection rigidity after concrete setting reaches intensity, it can be used for high anti-seismic requirement
Seismic region frame structure.
Detailed description of the invention
The utility model is described further with reference to the accompanying drawing.

Specific embodiment
1, the round steel pipe of certain wall thickness is selected according to structure Design and Calculation book；
2, four pieces of stiffeners are selected according to structure Design and Calculation book, and cut and meets design requirement；
3, four pieces of stiffeners are respectively welded in the mutually perpendicular side for passing through diameter of round steel pipe；
4, according to structure Design and Calculation book, selection four pieces of square plates of processing；
5, this four blocks of steel plates are respectively welded on the outside of frame stiffener, and weld the seam for the two blocks of steel plates that connect simultaneously,
Steel pipe column compound in this way is processed successfully；
6, column two sides are processed according to structure Design and Calculation book and connects girder steel；
7, the fixed compound steel pipe column of in-site installation；
8, it carries out compound steel pipe column and connect installation with girder steel；
9, casting concrete in the gap of the small steel pipe of inner circular and outboard square-like large steel pipe, and carry out maintenance and reach design
Intensity.
Claims (2)
1. a kind of compound concrete-filled tubular column -- steel beam joint, it is characterized in that: by outboard square-like large steel pipe, the small steel of central circular
