Body implication.
As shown in figure 1, the invention provides a kind of mortise and tenon type steel core concrete column connector, the connector include inserted link 4,
First steel core concrete column 1 and the second steel core concrete column 2, the end face of the first steel core concrete column 1 are provided with slot 1-2, the
The end face of two steel core concrete columns 2 is provided with the inserted block 2-2 coordinated with slot 1-2, extends transversely through to offer on inserted block 2-2 and is used for
The first through hole 2-3 of inserted link 4 is worn, second through hole 1- corresponding with first through hole 2-3 is equipped with the side wall of slot 1-2 both sides
3, i.e. first through hole 2-3 and the second through hole 1-3 quantity are identical, and after slot 1-2 and inserted block 2-2 grafting, first through hole 2-3 with
Corresponding second through hole 1-3 is coaxial.
Thus, staff only need to be by the inserted link 4 being prefabricated in the factory, the first steel core concrete column 1 and welding during construction
The second steel core concrete column 2 for the having inserted block 2-2 scene of transporting carries out assembled.It should be noted that inserted block 2-2 is except can
Beyond being welded with the second steel core concrete column 2, it can also be integrally formed with the second steel core concrete column 2.
When assembled：First, the inserted block 2-2 on the second steel core concrete column 2 is inserted into inserting on the first steel core concrete column 1
In groove 1-2；Then, one end of inserted link 4 is made to sequentially pass through the second through hole 1-3, inserted block in the one of side walls of slot 1-2
First through hole 2-3 on 2-2 and the second through hole 1-3 in slot 1-2 another side wall.It can be seen that the present invention is logical
Cross and weld prefabricated the first steel core concrete column 1 provided with slot 1-2 and the second steel core concrete column provided with inserted block 2-2 in factory
2, and open up the first through hole 2-3 passed through for inserted link 4 and the second through hole 1-3 respectively on inserted block 2-2 and slot 1-2 so that
During construction, staff need to only carry out simple assembly at the scene, and then not only eliminate welding and cast-in-place concrete
Link, greatly reduce the labor intensity of staff, improve efficiency of construction, reduce environmental pollution, but also need not
Extra auxiliary equipment, significantly reduces construction cost.In addition, by making inserted link 4 through inserted block 2-2 and slot 1-2, not only
Slot 1-2 and inserted block 2-2 relative movement can be constrained, and is also ensured between inserted block 2-2 side wall and slot 1-2 side wall
Reliably, pulling force is effectively transmitted.
Preferably, as shown in Fig. 2 the first steel core concrete column 1 includes the first housing 1-1 with the first accommodating chamber, the
Concrete 5 is cast with one accommodating chamber.Second steel core concrete column 2 includes the second housing 2-1 with the second accommodating chamber, inserted block
2-2 includes the shell with inner chamber, and the second accommodating chamber connects with inner chamber, to form filling chamber, and filling intracavitary is cast with concrete
5.It is highly preferred that the second housing 2-1 is integrally formed with shell.
Wherein, the first housing 1-1, the second housing 2-1 and shell material are ordinary steel, high strength steel, fire-resistant and weather-resistant steel
Or stainless steel.Concrete 5 is normal concrete or high performance concrete.
Preferably, the shape of cross section of the first steel core concrete column 1 and/or the second steel core concrete column 2 is rectangle, circle
Or ellipse.It should be noted that the shape of cross section of the first steel core concrete column 1 and/or the second steel core concrete column 2 is not
Rectangle, circle or ellipse are confined to, as long as its strength and stiffness can be ensured.
Preferably, inserted link 4 is pin.Wherein, the material of inserted link 4 is ordinary steel, high strength steel, fire-resistant and weather-resistant steel or stainless
Steel.
Preferably, first through hole 2-3 quantity is multiple that length directions of multiple first through hole 2-3 along inserted block 2-2 is successively
Set, that is to say, that also be provided with leading to first through hole 2-3 quantity identical second along slot 1-2 length direction on slot 1-2
Hole 1-3.During construction, multiple inserted links 4 are plugged in corresponding second through hole 1-3 and first through hole 2-3 by staff respectively, just
The active force suffered by each inserted link 4 can be significantly reduced, greatly improves the service life of inserted link 4.
Preferably, slot 1-2 quantity is multiple that inserted block 2-2 and slot 1-2 is corresponded.
Preferably, slot 1-2 is dovetail groove, and inserted block 2-2 is swallowtail-shaped structure.Wherein, dovetail groove and swallowtail-shaped structure
The big I at dovetail angle is determined according to the result of calculation of stress envelope, for example, the dovetail angle of dovetail groove and swallowtail-shaped structure
For 45~75 °.
In addition, the connector also includes pushing against part 3, inserted block 2-2 height is more than slot 1-2 depth, and the second steel pipe mixes
The end face of solidifying earth pillar 2 is provided with jack 2-4, and the first end for pushing against part 3 is inserted in jack 2-4, the second end is used for abutting first
The end face of steel core concrete column 1.Because inserted block 2-2 height is more than slot 1-2 depth, therefore when inserted block 2-2 is fully-inserted
When in slot 1-2, i.e., when inserted block 2-2 top surface contacts with slot 1-2 bottom surface, the end face of the first steel core concrete column 1 and the
There is gap, so as to which inserted link 4 is inserted into corresponding second through hole 1-3 and first through hole between the end face of two steel core concrete columns 2
After 2-3, staff just can adjust the end for pushing against the second end of part 3 relative to the second steel core concrete column 2 by the gap
The height in face, so that the second end for pushing against part 3 is supported located at the end face of the first steel core concrete column 1.And part 3 is pushed against to the first steel pipe
The end face of concrete column 1, which applies upward active force, can further compress inserted link 4, so as to ensure that abutting part 3, inserted link 4, insert
Pressure, shearing force, moment of flexure and moment of torsion can reliably, be effectively transmitted between block 2-2 and slot 1-2.
Wherein, it can be screw rod to push against part 3, and jack 2-4 is the screwed hole being connected with screw rod.During installation, staff
Spanner turn screw rod only need to be passed through, so that it may height of the top of adjusting bolt with respect to the end face of the first steel core concrete column 1.Need
Illustrate, the end face for how to push against by pushing against part 3 first steel core concrete column 1, those skilled in the art are easy to
Expect realizing by a variety of conventional meanses, for example abutting part 3 can also be by electromagnet, rod set and the magnetic shaft being inserted in rod set
Composition, electromagnet are fixedly mounted in jack 2-4, and rod set is fixedly mounted on the top of electromagnet, electromagnet are powered, by changing
Time-dependent current changes the polarity of electromagnet and electromagnetism intensity, electromagnet is produced opposite repulsive force to magnetic shaft, so that it may by magnetic
Property bar release rod set and push against the first steel core concrete column 1 end face；Or it is screw to push against part 3.
Finally it should be noted that：Above example is only to illustrate the technical scheme of invention, rather than its limitations；Although ginseng
Invention is described in detail according to previous embodiment, it will be understood by those within the art that：It still can be right
Technical scheme described in foregoing embodiments is modified, or carries out equivalent substitution to which part technical characteristic；And this
A little modifications are replaced, and the essence of appropriate technical solution is departed from the spirit and scope for inventing each embodiment technical scheme.
