Currently used architectural structure system can be divided into point with construction material：Reinforced concrete structure, steel-concrete group
Close structure, steel construction three classes.Reinforced concrete structure refers to the structure made of the concrete equipped with reinforcing bar enhancing, the master of load-bearing
Wanting component is built with armored concrete, and reinforcing bar bears pulling force, concrete bearing compressive force；Steel-concrete combined structure is steel
Component and concrete or bar-reinforced concrete member are combined into a kind of whole and cooperative structure, have both steel construction and reinforcing bar
Some characteristics of concrete structure；The structure that steel construction is made of steel material, the mainly steel made of shaped steel and steel plate etc.
The components such as beam, steel column, steel truss form.On-site wet operation amount is big when the construction of preceding diplobiont system, industrialization degree is low；And steel construction
For full factory process, in-site installation, industrialization degree is higher.In recent years, to promote building trade transition and upgrade, energy saving subtract is established
Row, low-carbon environment-friendly industry, China are encouraged to promote the development of assembled architecture, promote building industrialization, driven with this and entirely built
Build the development of industrialization.
Prefabricated construction is the product of industrialized production, while having construction rhythm fast, and good product quality, budget are made
Valence is low, and construction efficiency is high, the advantages such as simple production process.Prefabricated assembled component is readily produced and safeguards that economic benefit is very high,
Utilization scope is extensive, meets the current architectural industrialization development trend in China.Steel frame can be very good to realize the prefabricated of structure
Assembling, while having the characteristics that space is big, flexible arrangement, but for high building structure, the anti-side of Steel Frame Column is rigid
Spend the relative deficiency that seems.Steel-concrete coupled column can effectively improve the anti-side rigidity of structure, and with preferable economic effect
Benefit, but traditional steel-concrete coupled column needs a series of cumbersome technological processes such as shuttering, support, maintenance, form removal, and
Cannot synchronous with steel-frame beam assembly construction, cause the construction period long, the problems such as cost is higher than normal concrete structure, deviate from work
The core of industryization building quickly, economic, this just constrains application of the steel-concrete combined structure in assembled architecture.
Invention content
To solve the above problems, the present invention provides a kind of assembled steel-Combined concrete frame structure.

Stay bolt and lag bolt；The end of the prefabricated girder steel is equipped with end plate, the side of the prefabricated steel-concrete combination cylinder, institute
The side and the end plate for stating bean column node splicing apparatus are sequentially connected, the bottom surface of bean column node splicing apparatus and the pre-manufactured steel
The bottom wing listrium in beam bottom portion connects.
In one embodiment, the lag bolt is for being connected and fixed bean column node splicing apparatus；The stay bolt is used
It is fixed with nut after the end plate for connecting the prefabricated girder steel, installation positioning.
In one embodiment, the bean column node splicing apparatus is L-type.
In one embodiment, the side and bottom surface of the bean column node splicing apparatus are reserved with bolt hole.
In one embodiment, it is provided with bolt hole on the bottom wing listrium and the end plate.
In one embodiment, the quantity of angle steel is four.
In one embodiment, the angle steel is equal leg angle.
Assembled steel provided by the invention-Combined concrete frame structure, including it is prefabricated steel-concrete coupled column, prefabricated
Girder steel, bean column node splicing apparatus.The closure steel skeleton of prefabricated steel-concrete coupled column applies laterally about core concrete
Beam is at the stress state of three dimension stress, and the coupled column to be pressurized than existing single side improves about 2 times of bearing capacity,.
Simultaneously because the cross section of prefabricated steel-concrete coupled column is rectangle, there are certain spacing between batten plate on facade, this just has
The connectivity problem for solving bean column node of effect.Steel skeleton is stiffness load-bearing skeleton, and in the construction stage, it can play stiff skeleton
Effect, welding job can be realized by millwork, so as to greatly reduce site welding amount, improve working efficiency.
Assembled steel-Combined concrete frame structure of the present invention is detachable, is readily transported.Joint connection in site mainly uses high-strength bolt,
The wet construction for reducing scene, improves work efficiency, the use of high-strength bolt improves energy-dissipating property of the structure in earthquake.

Specific implementation mode
Below in conjunction with the drawings and specific embodiments to a kind of assembled steel-Combined concrete frame structure proposed by the present invention
It is described in further detail.According to following explanation and claims, advantages and features of the invention will become apparent from.It should be noted
That attached drawing is all made of very simplified form and uses non-accurate ratio, only to it is convenient, lucidly aid in illustrating this hair
The purpose of bright embodiment.
Embodiment one
Assembled steel-Combined concrete frame structure that the present embodiment one provides, including prefabricated steel-concrete coupled column,
Prefabricated girder steel and bean column node splicing apparatus.The structural schematic diagram of the prefabricated steel-concrete coupled column is as shown in Figure 1, include
Concrete 3 in steel skeleton and the steel skeleton；The steel skeleton is formed by 4 blocks of equal leg angles 1 and the welding of batten plate 2, and four
Face is closed；It is segmented to casting concrete 3 inside steel skeleton, forms steel-concrete column combination column；The steel skeleton is mixed to core space
Solidifying soil applies sidewise restraint, and the steel skeleton being closed at also has the function of resistance to side pressure template and stiffness load-bearing skeleton, with inside
Concrete 3 forms vertical bearing system together.It is reserved with including stay bolt 4 and short in the side of prefabricated steel-concrete coupled column
High-strength bolt including bolt 5.The bean column node splicing apparatus 7 uses L-type, and bolt hole is reserved in side and bottom surface.Institute
The side of the side and the bean column node splicing apparatus 7 of stating prefabricated steel-concrete coupled column is connected by the lag bolt 5；
