As shown in Figure 1, the present 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 equipped with slot 1-2, the
The end face of two steel core concrete columns 2 is equipped with the inserted block 2-2 that cooperates 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 on the side wall of the two sides slot 1-2
The quantity of 3, i.e. first through hole 2-3 and the second through-hole 1-3 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.
Staff only need to be by the inserted link 4 being prefabricated in the factory, the first steel core concrete column 1 and welding when constructing as a result,
There is the second steel core concrete column 2 of inserted block 2-2 scene of transporting to carry out assembled.It should be noted that inserted block 2-2 is in addition to can
Can also be integrally formed with the second steel core concrete column 2 with other than the welding of the second steel core concrete column 2.
When assembled: firstly, 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 slot 1-2；Then, one end of inserted link 4 is made to sequentially pass through the second through-hole 1-3, inserted block on the one of side wall of slot 1-2
First through hole 2-3 on 2-2 and the second through-hole 1-3 on another side wall of slot 1-2.As it can be seen that the present invention is logical
It crosses and welds prefabricated the first steel core concrete column 1 equipped with slot 1-2 in factory and equipped with the second steel core concrete column of inserted block 2-2
2, and open up the first through hole 2-3 and the second through-hole 1-3 passed through for inserted link 4 respectively on inserted block 2-2 and slot 1-2, so that
When 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 construction efficiency, reduce environmental pollution, but also be not necessarily to
Additional ancillary equipment, significantly reduces construction cost.In addition, by making inserted link 4 through inserted block 2-2 and slot 1-2, not only
The relative movement of slot 1-2 and inserted block 2-2 can be constrained, and is also ensured between the side wall of inserted block 2-2 and the side wall of slot 1-2
Reliably, pulling force is effectively transmitted.
Preferably, as shown in Fig. 2, the first steel core concrete column 1 includes the first shell 1-1 with the first accommodating chamber, the
Concrete 5 is cast in one accommodating chamber.Second steel core concrete column 2 includes the second shell 2-1 with the second accommodating chamber, inserted block
2-2 includes the shell with inner cavity, and the second accommodating chamber is connected to, to form filling chamber with inner cavity, and filling is intracavitary to be cast with concrete
5.It is highly preferred that second shell 2-1 and shell are integrally formed.
Wherein, the material of first shell 1-1, second shell 2-1 and shell 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 cross-sectional shape 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 cross-sectional shape of the first steel core concrete column 1 and/or the second steel core concrete column 2 is not
It is confined to rectangle, round or ellipse, as long as can guarantee its strength and stiffness.
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, the quantity of first through hole 2-3 be it is multiple, multiple first through hole 2-3 along inserted block 2-2 length direction successively
Setting, that is to say, that it is logical that the length direction on slot 1-2 along slot 1-2 also is provided with identical with first through hole 2-3 quantity second
Hole 1-3.When construction, multiple inserted links 4 are plugged in corresponding second through-hole 1-3 and first through hole 2-3 by staff respectively, just
Active force suffered by each inserted link 4 can be significantly reduced, the service life of inserted link 4 is greatly improved.
Preferably, the quantity of slot 1-2 is multiple, and inserted block 2-2 and slot 1-2 are 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 size at dovetail angle can be determined according to the calculated result of stress envelope, for example, the dovetail angle of dovetail groove and swallowtail-shaped structure
It is 45~75 °.
In addition, the connector further includes pushing against part 3, the height of inserted block 2-2 is greater than the depth of slot 1-2, and the second steel pipe is mixed
The end face of solidifying earth pillar 2 is equipped with jack 2-4, and the first end of abutting part 3 is inserted in jack 2-4, second end is for pushing against first
The end face of steel core concrete column 1.Since the height of inserted block 2-2 is greater than the depth of slot 1-2, when inserted block 2-2 is fully inserted into
When in slot 1-2, i.e. when the bottom surface of the top surface of inserted block 2-2 and slot 1-2 contact, the end face of the first steel core concrete column 1 and the
There is gap, so that 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 end of the second end for pushing against 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 set on 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, push against part 3 to ensure that, inserted link 4, insert
Pressure, shearing force, moment of flexure and torque can reliably, be effectively transmitted between block 2-2 and slot 1-2.
Wherein, pushing against part 3 can be screw rod, and jack 2-4 is the threaded hole being cooperatively connected with screw rod.When installation, staff
Spanner turn screw rod need to only be passed through, so that it may height of the top of adjustment screw with respect to the end face of the first steel core concrete column 1.It needs
Illustrate, for how to pass through the end face for pushing against part 3 and pushing against the first steel core concrete column 1, those skilled in the art are easy to
Expect realizing by a variety of conventional means, for example pushing against 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, are powered to electromagnet, by changing
Time-dependent current changes the polarity and electromagnetism intensity of electromagnet, so that electromagnet is generated 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 pushing against part 3 is screw.
Finally, it should be noted that above embodiments are only to illustrate the technical solution of invention, rather than its limitations；Although ginseng
Invention is described in detail according to previous embodiment, those skilled in the art should understand that: it still can be right
Technical solution documented by foregoing embodiments is modified or equivalent replacement of some of the technical features；And this
It modifies or replaces, the spirit and scope for each embodiment technical solution of invention that it does not separate the essence of the corresponding technical solution.
