Abstract
The utility model discloses a kind of steel concrete coupled columns, using hollow-core construction, including internal steel pipe and external reinforced concrete sandwich structure, the enhancing reinforcement structure of the external reinforced concrete sandwich structure is the steel reinforcement cage being sleeved on the outside of the internal steel pipe, and the more vertical pegs being evenly arranged are equipped on the outer surface of the internal steel pipe.The utility model is enhanced the anti-flexion capabilities of internal steel pipe, the bearing capacity of two kinds of materials of concrete and steel is more fully utilized using external reinforced concrete sandwich structural support and the internal steel pipe of constraint；Improve the interfacial bond property of concrete and steel pipe；External reinforced concrete sandwich structure not only can be with the common bearing load of internal steel pipe, also have the function of fire retardant anticorrosion erosion, solves the problems, such as that the exposed caused fire protecting performance of steel pipe is poor, saved fireproof coating and maintenance cost, project cost can be reduced, there is more significant comprehensive benefit.
Description
Technical field
The utility model is related to structural engineering field, more particularly to a kind of steel-concrete coupled column.
Background technology
In recent years, with the quickening of urban construction process and the development of Building technology, traditional reinforced concrete member because
The shortcomings of its poor seismic behavior, bearing capacity is not high, it is difficult to meet people to the ever-increasing functional requirement of structure, and composite structure
As a kind of by two or more combinations of materials cooperative new structure together, different materials can be given full play to
Respective advantage obtain more significant comprehensive benefit to preferably perfect frame performance.
Currently, steel core concrete column is to study a kind of coupled column component most concentrated, it in steel pipe by pouring coagulation
Soil and is formed, steel pipe and inner concrete bear vertically and horizontal loading, to have played the excellent of two kinds of materials of steel and concrete jointly
Point, to be used widely in skyscraper.For concrete filled steel tube coupled column there is also some problems, steel duct is mixed simultaneously
Solidifying soil volume-diminished after setting and hardening, concrete surface generate segregation phenomenon with steel pipe inner wall, cannot be compared under geological process
It cooperates well.Secondly, outer surface of steel tube is exposed is easy to be corroded in air, and change is easy tod produce when by fire
Shape, the above problem can all directly affect the holistic resistant behavior of column, and then jeopardize structure general safety, therefore actually use
In, outer surface of steel tube needs to brush fireproof coating and periodic maintenance, further increases project cost.
Invention content
The utility model provides a kind of steel-concrete coupled column to solve technical problem present in known technology, should
Coupled column can make two kinds of materials of concrete and steel preferably cooperate, and have the function of fire retardant anticorrosion erosion.
The utility model is adopted the technical scheme that solve technical problem present in known technology：A kind of steel-is mixed
Solidifying local soil type zygostyle, using hollow-core construction, including internal steel pipe and external reinforced concrete sandwich structure, the external reinforced concrete
The enhancing reinforcement structure of native iterative structure is the steel reinforcement cage being sleeved on the outside of the internal steel pipe, in the outer surface of the internal steel pipe
It is equipped with the more vertical pegs being evenly arranged.
The internal steel pipe and the external reinforced concrete sandwich structural section shape are all rectangle.
The steel reinforcement cage indulges muscle a diameter of 12mm-20mm, stirrup diameter 6mm-10mm, stirrup spacing 100mm-
200mm。
The thickness of the external reinforced concrete sandwich structure is 50mm-100mm.
The utility model has the advantages and positive effects of：Using external reinforced concrete sandwich structural support and constraint
Internal steel pipe enhances the anti-flexion capabilities of internal steel pipe, and the carrying of two kinds of materials of concrete and steel is more fully utilized
Ability；Improve the interfacial bond property of concrete and steel pipe；External reinforced concrete sandwich structure not only can be with internal steel
Common bearing load is managed, also has the function of fire retardant anticorrosion erosion, solves the problems, such as that the exposed caused fire protecting performance of steel pipe is poor, section
About fireproof coating and maintenance cost, can reduce project cost, have more significant comprehensive benefit.

In figure：Steel pipe inside 1-, the vertical pegs of 2-, the outsides 3- reinforced concrete sandwich structure, 4- stirrups, 5- indulge muscle.
Specific implementation mode
For that can further appreciate that the invention, features and effects of the utility model, the following examples are hereby given, and coordinates
Detailed description are as follows for attached drawing：
It please refers to Fig.1 and Fig. 2, a kind of steel-concrete coupled column, using hollow-core construction, including internal steel pipe 1 and external steel
Reinforced concrete iterative structure 3, the enhancing reinforcement structure of the external reinforced concrete sandwich structure 3 are to be sleeved on the internal steel pipe
The steel reinforcement cage in outside is equipped with the more vertical pegs 2 being evenly arranged on the outer surface of the internal steel pipe 1.
In the present embodiment, the internal steel pipe 1 and external 3 cross sectional shape of reinforced concrete sandwich structure are all square
Shape.Vertical the muscle preferred 12mm-20mm of 5 diameter, the preferred 6mm-10mm of stirrup diameter, the preferred 100mm- of stirrup spacing of the steel reinforcement cage
200mm.The preferred 50mm-100mm of thickness of the external reinforced concrete sandwich structure 3.
When construction, vertical peg 2 is welded on the outer surface of internal steel pipe 1, is then bound in periphery and is indulged muscle 5 and stirrup 4,
Form steel reinforcement cage；Subsequently supporting module and the concrete of external reinforced concrete sandwich structure 3 is poured, forms steel-concrete
Coupled column.
Although the preferred embodiment of the utility model is described above in conjunction with attached drawing, the utility model is not
It is confined to above-mentioned specific implementation mode, the above mentioned embodiment is only schematical, is not restrictive, ability
The those of ordinary skill in domain is not departing from the utility model aims and claimed under the enlightenment of the utility model
In the case of range, many forms can also be made, these are belonged within the scope of protection of the utility model.
