Hinder after connecting node destroys in end plate weld joint region, connecting node still works in an articulated manner.
Detailed description of the invention
In order to keep the purpose of this utility model, technical scheme and beneficial effects clearer, the utility model provides as follows
Attached drawing is illustrated:
Fig. 1 is the structural schematic diagram of the utility model；
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 embodiment
Below in conjunction with attached drawing, the preferred embodiment of the utility model is described in detail.
As shown in Figure 1-3, the Concrete-filled tubular connections in the present embodiment, including steel core concrete column 1, it 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 in the corner portion of steel core concrete column 1 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 from outside to inside and three tighten together.?
In the structure, angle steel 4 plays effect of contraction to end plate 3 in being coated on 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.4 both sides of the angle steel correspondence that 1 four corners of steel core concrete column are arranged in is coated on two abutting ends
The outside of plate 3, i.e. the every of angle steel 4 are coated on one side outside the end plate of I-beam web lateral position, 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 two sides of I-beam web different, thus reach share the moment of flexure acted on node,
The effect of shearing and axle power is strong by presetting the weld seam between I-beam and end plate under the premise of guaranteeing anchor bolt rigidity, intensity
Degree, can make the node be in controllable state during the work time.
As shown in figure 4, further including the angle steel being arranged between steel core concrete column 1 and I-shaped flange of beam 21 in the present embodiment
II 6, the angle steel II 6 is W formula structure made of two right angle angle steel connect, and the both sides positioned at outside are right by anchor bolt 5 thereon
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 and steel core concrete column 1 have angle steel
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, for combination connection, are had 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, even if so that node end plate occurs
Destruction also possesses enough ductility conversion force-mechanisms and forms secondary protection, 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 guarantees 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.
Angle steel 4 herein can use ordinary steel, high-strength alloy steel, stainless steel or refractory steel material；Anchor bolt material is optional
