To solve the above problems, the utility model provides a kind of assembled steel-Combined concrete frame structure.
Assembled steel provided by the utility model-Combined concrete frame structure, including prefabricated steel-concrete coupled column, Prefabricated girder steel and bean column node splicing apparatus;The prefabricated steel-concrete coupled column includes being welded with multiple angle steel and multiple batten plates The concrete for connecing the steel skeleton to form closure and being poured inside the steel skeleton, it is pre- in prefabricated steel-concrete combination column side face Equipped with 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 Face, the bean column node splicing apparatus side and the end plate be sequentially connected, the bottom surface of bean column node splicing apparatus with it is described The bottom wing listrium of prefabricated steel beam bottom 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 utility model-Combined concrete frame structure, including prefabricated steel-concrete coupled column, Prefabricated girder steel, bean column node splicing apparatus.The closure steel skeleton of prefabricated steel-concrete coupled column applies core concrete lateral Constraint, 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 carrying energy Power,.Simultaneously because the cross section of prefabricated steel-concrete coupled column is rectangle, there are certain spacing between batten plate on facade, this With regard to the connectivity problem of effective solution bean column node.Steel skeleton is stiffness load-bearing skeleton, and in the construction stage, it can play stiffness bone The effect of frame, welding job can be realized by millwork, so as to greatly reduce site welding amount, improve work effect Rate.The assembled steel of the utility model-Combined concrete frame structure is detachable, is readily transported.Joint connection in site mainly uses height Strength bolt reduces the wet construction at scene, improves work efficiency, the use of high-strength bolt improves consumption of the structure in earthquake It can performance.

Specific implementation mode
Below in conjunction with the drawings and specific embodiments to the utility model proposes a kind of assembled steel-Combined concrete frame Structure is described in further detail.According to following explanation and claims, will be become apparent from feature the advantages of the utility model. 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 assist Illustrate the purpose of the utility model 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; The end set of the prefabricated girder steel 6 has end plate 8, the corresponding position on the bottom wing listrium of 6 bottom of the end plate 8 and prefabricated girder steel Prepared screw-bolt hole, the side of prefabricated steel-concrete combination cylinder, the side of the bean column node splicing apparatus 7 with it is described End plate 8 is sequentially connected by the stay bolt 4, forms assembled steel-Combined concrete frame structure.
Specifically, the length of side of equal leg angle 1 is 90mm, thickness 12mm, quantity is four;Batten plate 2 uses the steel of 8mm thickness Plate is cut, and is longitudinally welded along 4 blocks of equal leg angles, and the closed type steel skeleton of rectangle is formed.When closed type steel skeleton is complete At later, the spatial domain in steel skeleton is filled up with pump concrete and vibration compacting, closure steel skeleton also have resistance to side pressure template With the effect of stiffness load-bearing skeleton, the work of formwork form removal is eliminated, maintenance waits for concrete strength to reach requirement and can be used.
The corresponding node location in prefabricated steel-concrete coupled column side is laterally reserved long and short;Two kinds of high-strength bolts, The boom end of bolt is to exposing outside.When assembled first with it is reserved it is long and short be bolted the bean column node splicing apparatus 7, and first Lag bolt 5 is fixed with nut, first carries out the bean column node splicing apparatus 7 and prefabricated steel-concrete coupled column It is fixedly connected.The end of the prefabricated girder steel 6 is welded with end plate 8, will when installation in 8 corresponding position prepared screw-bolt hole hole of end plate The end plate 8 and the stay bolt 4 of the prefabricated steel-concrete coupled column carry out assembly, and nut is used in combination to be connected and fixed.In pre-manufactured steel Prepared screw-bolt hole hole on the bottom wing listrium of 6 bottom of beam, is spliced with the bottom surface of bean column node splicing apparatus 7, and high-strength spiral shell is used in combination Bolt is fixed.
Show assembled steel-Combined concrete frame that the utility model is proposed by theory analysis and engineering practice Structure is keeping self-respect close and bearing capacity under the same conditions, can save steel about percent compared with traditional steel frame 50, welding job amount can be greatly reduced;Compared with steel reinforced concrete frame structure, holding member cross-sectional area it is close and Bearing capacity under the same conditions, can save steel 50 about percent, and construction is more easy;With ordinary reinforced concrete frame Structure is compared, keep that rolled steel dosage is close and bearing capacity under the same conditions, element cross-section area can be reduced by about one Half, to which the effective area of building is increased, the dosage and member dead weight of concrete and cement accordingly reduce about percent 50.
Although the utility model has been described by way of example and in terms of the preferred embodiments, it is not limited to the utility model, any Person skilled in the art can do various change and modification, therefore this without departing from the spirit and scope of the utility model The protection domain of utility model should be subject to what claims were defined.
