(2) angle steel being directly coated on outside end plate can make the anchor bolt Impact direction of I-beam web both sides different, to reach
To the effect for sharing the moment of flexure acted on node, shearing and axle power, under the premise of ensureing anchor bolt rigidity, intensity, by pre-
If the weld strength between I-beam and end plate, you can the node is made to be in controllable state during the work time.
(3) angle steel II is arranged between steel core concrete column and I-shaped flange of beam, i.e., between original I-shaped flange of beam and end plate
Plastic hinge is increased again on the basis of welding, when being pressurized above I-beam, angle steel II, which can destroy the non-ductile of commissure, to be turned
Become ductile fracture.
(4) it in the Concrete-filled tubular connections, is welded between I-beam and end plate, I-beam has angle steel II with steel core concrete column
Connection, it is that combination connects that end plate has Bolted angle connection, total with concrete filled steel tube intercolumniation so that node is integrally provided simultaneously with two
Kind failure mechanism.Angle steel, angle steel II and anchor bolt enhance the ductility and robustness of join domain so that even if node end plate occurs
It destroying and also possesses enough ductility conversion force-mechanism formation secondary protections, i.e. angle steel II forms plastic hinge in end of I beam,
The cooperative transformation ability of I-beam is substantially increased, stretched wire effect is formed and ensures that Progressive Collapse will not occur for structure；Protect
Hinder after connecting node destroys in end plate weld joint region, connecting node still works in an articulated manner.
Description of the drawings
In order to keep the purpose of the present invention, technical solution and advantageous effect clearer, the present invention provides following attached drawing and carries out
Explanation：
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the positive schematic diagram of Fig. 1；
Fig. 3 is the transverse sectional view of Fig. 1；
Fig. 4 is the structural schematic diagram for adding angle steel II.
Specific implementation mode
Below in conjunction with attached drawing, the preferred embodiment of the present invention is described in detail.
As shown in Figs. 1-3, the Concrete-filled tubular connections in the present embodiment, including steel core concrete column 1, further include I-beam
2, end plate 3 and angle steel 4；The end plate 3 is welded on 2 end of I-beam and is fixed in the peripheral surface of steel core concrete column 1,
The angle steel 4 be right angle angle steel, be arranged steel core concrete column 1 corner portion and thereon two right-angle sides correspondence be coated on end plate
3 outside, anchor bolt 5 sequentially pass through angle steel 4, end plate 3 and steel core concrete column 1 and three tighten together from outside to inside.
In the structure, angle steel 4 plays effect of contraction in being coated on end plate 3 to end plate 3, and anchor bolt 5 initially passes through angle steel 4, is then passed through
The setting of end plate 3, and anchor bolt 5 is improved to 3 fastening effect of end plate so that between 1 three of angle steel 4, end plate 3 and steel core concrete column
It connects more reliable, so that the switching performance of structure entirety is more preferable, there is better bearing capacity and ductility.
In the present embodiment, it is respectively and fixedly provided with end plate 3 and I-beam 2 on four faces of the steel core concrete column 1 of rectangular in cross-section,
Each I-beam is in sustained height face.It is arranged to correspond on 4 both sides of angle steel of 1 four corners of steel core concrete column and is coated on two abutting ends
Every one side in the outside of plate 3, i.e. angle steel 4 is coated on outside the end plate at I-beam web side, and each end plate is by two groups of angle steel
Corresponding cladding.In the structure, each side of angle steel is directly coated on the end plate between two edge of a wing 21 of I-beam, herein angle steel
Setting can make anchor bolt 5 Impact direction of 22 both sides of I-beam web different, to reach share the moment of flexure acted on node,
The effect of shearing and axle power is strong by default weld seam between I-beam and end plate under the premise of ensureing anchor bolt rigidity, intensity
Degree, you can the node is made to be in controllable state during the work time.
Further include the angle steel being arranged between steel core concrete column 1 and I-shaped flange of beam 21 as shown in figure 4, in the present embodiment
II 6, the angle steel II 6 is W formula structures made of two right angle angle steel connect, and the both sides for being located at outside thereon are right by anchor bolt 5
It should be connected on steel core concrete column 1 and each I-shaped flange of beam 21, and corner bending structure in an intermediate position is then used to allow
Position end plate.Specifically, the setting of angle steel II 6 herein, on the basis of original welding (welding between I-shaped flange of beam and end plate)
Plastic hinge (Bolted angle connection between I-shaped flange of beam and steel core concrete column 1) is increased again, when being pressurized above I-beam, angle steel
II 6 setting, which can destroy the non-ductile of commissure, is transformed into ductile fracture.
It in the Concrete-filled tubular connections, is welded between I-beam 2 and end plate 3, I-beam 2 has angle steel with steel core concrete column 1
II 6 connections have the connection of angle steel 4, wherein angle steel II 6 is I-beam 2 and concrete filled steel tube between end plate 3 and steel core concrete column 1
Secondary connection between column 1, total include being rigidly connected and being flexibly connected two kinds of connection types, connect for combination, have simultaneously
Standby two kinds of failure mechanisms.
Angle steel 4, angle steel II 6 and anchor bolt 5 enhance the ductility and robustness of join domain so that even if node end plate occurs
It destroying and also possesses enough ductility conversion force-mechanism formation secondary protections, i.e. angle steel II 6 forms plastic hinge in end of I beam,
The cooperative transformation ability of I-beam is substantially increased, stretched wire effect is formed and ensures that Progressive Collapse will not occur for structure；Protect
Hinder after connecting node destroys in end plate weld joint region, connecting node still works in an articulated manner.
Ordinary steel, high-strength alloy steel, stainless steel or refractory steel material may be used in angle steel 4 herein；Anchor bolt material is optional
With high strength stainless steel, high-strength alloy steel or high-strength refractory steel, certainly or rolled products of ordinary high-strength anchor bolt, structure can be
Staight scissors anchor bolt or blind anchor bolt.Here by angle steel and anchor bolt material is reasonably selected, the deformation for enhancing this junction can be corresponded to
Ability and refractory ability, to further improve the stress performance of node.
Finally illustrate, preferred embodiment above is merely illustrative of the technical solution of the present invention and unrestricted, although logical
It crosses above preferred embodiment the present invention is described in detail, however, those skilled in the art should understand that, can be
Various changes are made to it in form and in details, without departing from claims of the present invention limited range.
