Description
Technical field
It the utility model is related to civil construction field beam-to-column joint construction, particularly a kind of concrete filled steel tube combined special-shaped column
With H profile steel beam connecting structure.
Background technology
Irregular CFRT column is to be interconnected to constitute by single steel core concrete column by lacing, has L-shaped, T
Three kinds of section forms of shape and cross, separately available corner post, side column or the center pillar for making to build.The spy of irregular CFRT column
Point is that section form is flexible, and single limb column can be wrapped in inside wall, avoid indoor corner from salient angle occur, and with less section shape
Formula obtains larger two-way bending stiffness.
Node is the key position in framework design, and the difficult point of construction, it is played in beam and two kinds of components of column
Between transmit moment of flexure and shearing effect.If node cannot provide the constraint needed for rod end power, structural behaviour will be made
Change, so that it cannot be guaranteed that the correctness of computation model, causes the ultimate strength of structure to be also different from the predicted value of designer, directly
Connect the security for being related to structure.Rectangular steel tube with concrete infilled joint form is varied, such as inner diaphragm joint, outer ring plate section
Point, partition plate perforation node, external rib circular board node etc..The flange of beam and internal partition of inner diaphragm joint apply in post jamb same place both sides
Melt-through weld, produces larger welding and participates in stress, post jamb is also easy to produce tear, and inner diaphragm joint is not suitable for section ruler
In very little less steel core concrete column；The strength and stiffness of outer shroud plate node are protected by the larger horizontal baffle of column side dimension
Card, therefore larger space is occupied, and make it that ring flat-plate is exposed, influence space use；Partition plate perforation node is a kind of beam perforation
Node, has good anti-seismic performance, but every layer of column will be interrupted, be not suitable for special-shaped column composed of concrete-filled square steel tubes-
Steel beam joint.
On the basis of external partition node, the horizontal outer ring plate of its other both sides is changed to the smooth vertical rib in column side
Plate, also needs steel beam flange being welded on to transmit beam-ends moment of flexure on vertical floor, so as to form traditional external rib circular board node.But this
When kind joint form is used for special-shaped column composed of concrete-filled square steel tubes-steel beam joint, there are between outer floor and the single limbs of Special-Shaped Column two
Connecting plate and its stiffener connection are difficult, are not easy to welding and the indefinite problem of power transmission.
The content of the invention
To there is provided a kind of concrete filled steel tube combined special-shaped to solve technical problem present in known technology for the utility model
Column and H profile steel beam connecting structure, the outer floor that this is configured to make external rib circular board node is with the connection structure of column limb connecting component
Simply, power transmission is clearly reliable and easy for construction.
The utility model is adopted the technical scheme that to solve technical problem present in known technology：A kind of steel pipe mixes
Solidifying soil combined special-shaped column and H profile steel beam connecting structure, the concrete filled steel tube combined special-shaped column are equipped with 3~5 column limbs, the column
Limb by the horizontal ring flat-plate of twice it is opposite with two flange plates of the H profile steel beam welding, the column limb by web connecting plate with
The web connection of the H profile steel beam, is equipped with vertical floor in the both sides of the horizontal ring flat-plate, and the vertical floor is across described
Column limb is connected with column limb connecting component, and the column limb connecting component is arranged between two column limbs, and the column limb connecting component is set
There are two side plates to link together, the both ends of the side plate are connected with two column limbs respectively, two side plate difference
It is set in parallel and is welded in the inner side of two vertical floors, the side plate with the vertical floor lapping on the outside of it
Connect, the vertical floor is flattened on the outside of the column limb, the two welding.
The column limb connecting component is using made of horizontally disposed square steel tube, and the both ends of the square steel tube are respectively with two
A column limb connection, two vertical side walls of the square steel tube are formed described in two of a column limb connecting component respectively
Side plate.
The column limb connecting component is used made of the H profile steel being vertically arranged, the two of two flange plates of the H profile steel
End is connected with two column limbs respectively, and two flange plates of the H profile steel form column limb connecting component respectively
Two side plates.
A reinforcement connecting plate is respectively provided with the outside of two flange plates of the H profile steel, the reinforcement connecting plate is welded on
On the outside of the flange plate of the H profile steel, the vertical floor is welded with the outside of the reinforcement connecting plate.
The utility model has the advantages and positive effects of：1) it is simple in structure, it is convenient to process and mount, power transmission clearly may be used
Lean on, overcome outer shroud plate node and easily cause indoor corner to have the problem of salient angle；2) the column limb of irregular CFRT column connects
Relay part is used with two structures of side plate easy to be connected with floor, solves traditional external rib circular board node form for side
During concrete filled steel tube combined special-shaped column-steel beam joint, there are connecting plate and its stiffener between outer floor and the single limb of Special-Shaped Column two
Connection is difficult, is not easy to welding and the indefinite problem of power transmission；3) two pieces of vertical floors are affixed on post exterior side, with steel beam position
Between corresponding two column limbs of irregular CFRT column set square steel tube or ratio-frequency welding H profile steel perforation, it is this be configured to by
The advantage of external rib circular board node and steel pipe concrete profiled pile gives full play to, and not only ensure that node was reliably connected, but also realize room
Inner corner portion increases usable floor area without pillar salient angle.4) due to the quadrate steel pipe column side of use in low layer and multistoried housing construction
It is long usually smaller, inner diaphragm joint can not be used, therefore the construction also has in processing and fabricating from the limitation of the steel pipe length of side
Advantage；5) steel pipe column of external rib circular board node continuously penetrates through, and has adapted to industrial production demand, in particular with cold bending thin wall steel
The operation of pipe large-scale production line and the development of steel structure of housing, the advantage of this kind of node will be played preferably, be a kind of value
Obtain the joint form of research and extension.
