Abstract
The present invention relates to a kind of interior nodes for setting PBL rib square sets and justifying Concrete-filled Double Skin Steel Tube Columns and girder steel, including outer square steel tube 1, interior round steel pipe 2, outer annular-stiffer 3, PBL ribs 4, concrete 5, girder steel 6, weld seam 7；The PBL ribs are symmetricly set at nodes domains along the outer surface in inner circle length of steel pipe direction, and PBL ribs are connect with outer round steel pipe using fillet weld with interior round steel pipe, outer annular-stiffer；Girder steel is all made of butt welding welding with outer annular-stiffer, invention increases the contacts area of interior round steel pipe and concrete, enhance the rigidity of nodes domains, enhance the shear resistance and non-deformability of joint cores, the node has reasonable stress, power transmission is clear, has many advantages, such as that higher installation progress, speed of application are fast.
Description
Technical field
The present invention relates to a kind of interior node for setting PBL rib square sets and justifying Concrete-filled Double Skin Steel Tube Columns and girder steel, dependent territory is built
Structure node technical field.
Background technology
For concrete filled steel tube as a kind of composite structure that development prospect is wide, it has given full play to the excellent of steel pipe and concrete
Point, with the development of modern architecture, concrete filled steel tube gradually embody its superiority be widely used in industrial premises, high level and
In high-rise building, bridge.And Concrete-filled Double Skin Steel Tube Columns are necessarily involved in application process and are applied at present more
The connecting node problem of rigid Vierendeel girder, and be always the principal element for restricting hollow steel tube concrete structure and promoting.At this stage
Most of processing concrete-filled double skin steel tube is punched with the problem of steel beam joint using half interspersed method of girder steel but steel pipe walls
Concrete filled steel tube intensity will be substantially reduced afterwards, and apparent sheared destruction occurs in node.A kind of reasonable stress of present invention offer, power transmission
Clearly, outer and inner tube can cooperate very well, nodes domains rigidity is big, bearing capacity is big, energy dissipation capacity is preferable, speed of application is fast,
The node that PBL rib square sets circle Concrete-filled Double Skin Steel Tube Columns and girder steel are set in widely applicable, has a good application prospect.
Invention content
The object of the present invention is to for concrete-filled double skin steel tube bean column node design there are the problem of.The present invention
It proposes to set the node that PBL rib square sets justify Concrete-filled Double Skin Steel Tube Columns and girder steel in a kind of.
Technical scheme is as follows：PBL rib square sets circle Concrete-filled Double Skin Steel Tube Columns and girder steel are set in a kind of
Node, including outer square steel tube, interior round steel pipe, outer annular-stiffer, PBL ribs, concrete, girder steel, weld seam.The PBL ribs are in nodes domains
Place is symmetricly set on along the outer surface in inner circle length of steel pipe direction, and outer annular-stiffer connects vertical welding in outer circle using fillet weld
One end of steel pipe, left and right girder steel is directly welded on using butt welding on reinforcing ring, and outer square steel tube concentric need to be placed with interior round steel pipe
Cavity is formed, then pours air-free concrete into cavity.
Square set circle hollow sandwich outer steel pipe section is rectangular, and the section of interior steel pipe is circle.
The girder steel is I section steel beams, H profile steel beam.
All connections are welding.
It is an advantage of the invention that only being welded, hole need not be punched on steel pipe to influence hollow sandwich steel pipe
The rigidity and ductility of concrete column and steel beam joint, steel pipe partial buckling can be effectively reduced by inside setting the interior round steel pipe of PBL ribs, be increased
Adding interior round steel pipe and the contact area of concrete, increases the rigidity and non-deformability of joint cores, Path of Force Transfer is clear,
High capacity, to preferably solve the problems, such as steel beam connecting joint.

Specific implementation mode
The present invention is described in detail below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, by steel pipe in the outer square steel tube of design size processing square set circle hollow sandwich, circle, PBL ribs, outer
Reinforcing ring and girder steel；PBL ribs 4 are welded on steel pipe 2 in circle by design position, ribbed stiffener 4 is symmetrical above and below to be distributed in nodes domains, and
Square set circle hollow sandwich reinforcing ring 3 is vertically welded in the design position of outer square steel tube 1, steel pipe in circle 2 and circle set circle is hollow
1 arranged concentric of interlayer outer steel pipe forms cavity, then air-free concrete is poured into cavity, waits for that concrete curing reaches design strength
Girder steel 6 and reinforcing ring 3 are used to be welded to connect to be formed in one kind again when value and sets PBL rib square sets circle Concrete-filled Double Skin Steel Tube Columns
With the node of girder steel.
