Description
Technical field
The invention belongs to building engineering fields, and in particular to a kind of self-locking concrete-filled circular steel tube column node.
Background technique
The connection of traditional concrete-filled circular steel tube column and precast concrete beam mainly includes two major classes: the first kind is to reinforce
Loop joint, ring beam joint, reinforcing bar circulating type node etc. be representative non-punching node, the second class be with bracket punching node,
Reinforcing bar penetration type node, cross gusset-type joint etc. are the punching node of representative.Above-mentioned two classes node on behalf round steel pipe coagulation
The usual way that earth pillar is connect with the various beams such as girder steel, reinforced beam and steel tube concrete beam, the above method usually require
A large amount of weld jobs are carried out in shaft, or even local failure (such as perforate, punch) is caused to shaft.These methods not only construct
Complexity also makes pouring for column inner concrete become more difficult, and the local failure for existing simultaneously column reduces bearing capacity
Risk.
Summary of the invention
The present invention is based on above situation, propose that a kind of self-locking concrete-filled circular steel tube column node, the node use prefabricated structure
Part assembled in situ, simple structure and easy for construction farthest improve construction efficiency and are easy to quality control.The section simultaneously
Point will not only cause local damage to column, but also will not generate any influence to the pouring of pipe inner concrete, can guarantee to greatest extent
The safety of main structure provides safeguard for people's life security.
To achieve the above object, self-locking concrete-filled circular steel tube column node provided by the invention, it is characterised in that: including pre-
Node and concrete-filled circular steel tube column processed；The prefabricated node is integral type node, and the inner wall and round steel pipe of the prefabricated node are mixed
The outer wall socket of solidifying earth pillar；The prefabricated node is vertically provided with two-way conical bore, and node circle is equipped in the two-way conical bore
The conical surface, the two-way conical bore are inserted in concrete-filled circular steel tube column to proper height, and altitude range determines principle: pre- after the completion of socket
1 top surface absolute altitude of node processed should be consistent with the floor plate top surface designed elevation, and error is not more than 1cm, facilitates subsequent beam and node
Connection and floor slab construction；
Clip assemblies are equipped with below the two-way conical bore with fixation；The clip assemblies are to be surrounded by identical three intermediate plates
And the cone to match with node circular conical surface, the clip assemblies inside are provided with screw thread to increase bite force；
The size of the two-way conical bore is opposite with the side dimension of cone that three intermediate plates of the clip assemblies surround
It answers.
The advantages of the present invention are as follows:
1) connection of the node and column is jacket-type connection, will not generate any influence to the pouring of column inner concrete,
Local damage will not be caused to column since node connects, ensure that the safety of main structure to the maximum extent.
2) the vertical shear transport mechanism of node is similar to the anchor mechanism of single hole anchor device, the vertical shear transmitted by beam-ends
Via strand tapered anchorage, it is converted into the hoop tension of node vertical section, takes full advantage of the good advantage of steel tensile property, simultaneously
Node force-transmission mechanism is simply clear.
3) node uses prefabricated components assembled in situ, and joint connection in site the dry connections side such as anchors, is bolted using intermediate plate
Method, has the advantages that convenient, fast, increases substantially construction efficiency, industrialization degree is high.

Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
Self-locking concrete-filled circular steel tube column node as shown in the figure, including prefabricated node 1 and concrete-filled circular steel tube column 3；In advance
Node 1 processed is integral type node, and the inner wall of prefabricated node 1 and the outer wall of concrete-filled circular steel tube column 3 are socketed；Prefabricated node 1 is vertical
It is provided with two-way conical bore 101, is equipped with node circular conical surface in two-way conical bore 101, two-way conical bore 101 is inserted in round steel pipe coagulation
Earth pillar 3 to proper height, altitude range determines principle: prefabricated 1 top surface absolute altitude of node should be with the floor plate top surface after the completion of socket
Designed elevation is consistent, and error is not more than 1cm, facilitates connection and the floor slab construction of subsequent beam and node；Under two-way conical bore 101
Side is equipped with clip assemblies 2 with fixation；Clip assemblies 2 are the circular cone for being surrounded and being matched with node circular conical surface by identical three intermediate plates
Shape is provided with screw thread to increase bite force on the inside of clip assemblies 2；The size and 2 three intermediate plates of clip assemblies of two-way conical bore 101
The side dimension of the cone surrounded is corresponding.
Self-locking concrete-filled circular steel tube column node of the invention, divides the following steps to construct:
The production of concrete-filled circular steel tube column: external round steel pipe 301 is lifted in place first, guarantees its verticality, then pours
It builds concrete 302 and conserves 28 days, form concrete-filled circular steel tube column 3.(1. 301 steel pipe: for the common circular cross-section steel pipe in market,
Material can be, but not limited to, 235 steel of common Q, zinc-plated stainless steel and special steel etc..2. 302 concrete: generally on the market
It is mixed to be also possible to self-compacting concrete, steel fiber reinforced concrete, self-stressing concretes, seif-citing rate self-compaction for common commerical ready-mixed concrete
The properties concrete such as solidifying soil, steel fibre seif-citing rate self-compacting concrete and regenerated aggregate concrete.)
Node installation: prefabricated node 1 is from top to bottom inserted in concrete-filled circular steel tube column 3 to proper height, notices that node is double
It is following up-small and down-big at this time to 101 middle part of conical bore, then clip assemblies 2 are inserted into conical bore by lower section, to prefabricated node 1
Force downwards guarantees that clip assemblies 2 are not deviate from by the self weight of prefabricated node 1 and threaded engagement.By the concrete-filled circular steel tube column 3 on upper layer
It is put into the prefabricated node 1 and is from top to bottom put into clip assemblies 2, complete installation.
