Abstract
The utility model discloses a kind of multi-cavity steel tube concrete column, including cylinder, square steel tube, round steel pipe, U-shaped steel, dowel, the column body is by square steel tube, round steel pipe, U-shaped steel, dowel forms, casting concrete outside the cylinder, the round steel pipe both ends set square steel tube, connected between the round steel pipe by dowel, connected between the square steel tube by U-shaped steel, two sides of the U-shaped steel set through hole, the square steel tube, concrete perfusion inside round steel pipe, the dowel of the round steel pipe both sides is set in X-type cross；Generally, the utility model has the advantages that filling concrete convenience, high capacity, shear behavior are good.
Description
Technical field
The utility model belongs to technical field of building construction, more particularly to a kind of multi-cavity steel tube concrete column.
Background technology
Concrete filled steel tube refers to the fill concrete in steel pipe and is formed and steel pipe and its core concrete can be born jointly
The structural elements of external load effect, it is different by section form, concrete filled steel tube can be divided into, side, concrete-filled rectangular steel tube and more
Side shape concrete filled steel tube etc..It is well known that the compression strength of concrete is high.But bending resistance is very weak, and steel, particularly shaped steel
Bending resistance it is strong, there is good elastoplasticity, but when being pressurized easy unstability and lose axial compression resistance ability.And steel tube concrete
Soil is combined together can be by the two in structure the advantages of, concrete can be made to be in side loaded state, its compression strength can
Is significantly improved simultaneously because the presence of concrete, improves the rigidity of steel pipe, both play a role jointly, so as to greatly carry
High bearing capacity.Concrete filled steel tube is as a kind of emerging combining structure, mainly with axial compression and active force small eccentricity
Compression member based on, be widely used in frame structure (such as workshop and high level).Concrete filled steel tube develops rapidly
It is due to that it has good stress performance and workability.
The content of the invention
The purpose of this utility model is to provide a kind of multi-cavity steel tube concrete column, which closes
Manage, is simple in structure, facilitating concrete perfusion, the fastener for connection of column body is firm, has high use value.
What the purpose of this utility model was realized in：A kind of multi-cavity steel tube concrete column, including cylinder, square steel tube, circle
Shape steel pipe, U-shaped steel, dowel, the column body are made of square steel tube, round steel pipe, U-shaped steel, dowel, the column
Casting concrete outside body, the round steel pipe both ends set square steel tube, are connected between the round steel pipe by dowel
Connect, connected between the square steel tube by U-shaped steel.
Two sides of the U-shaped steel set through hole.
Concrete perfusion inside the square steel tube, round steel pipe.
The dowel of the round steel pipe both sides is set in X-type cross.
The utility model produce beneficial effect be：First, the utility model sets the both ends of column body round steel pipe
Square steel tube is set to, on the one hand improves the bearing capacity at cylinder both ends itself, is on the other hand more favorable in construction by steel pipe
It is fixed.Second, the utility model sets the dowel in X-type cross in the both sides of round steel pipe, make the company between round steel pipe
It is more firm to connect, while also improves the shear resistance of cylinder.Third, two sides of the utility model U-shaped steel set through hole,
Filling concrete is convenient for, prevents from being effectively filled into the U-type groove of U-shaped steel during filling concrete.

Embodiment
Below in conjunction with the accompanying drawings to the embodiment further instruction of the utility model.
Embodiment 1
As illustrated in the accompanying drawings from 1 to 3, a kind of multi-cavity steel tube concrete column, including cylinder 1, square steel tube 2, round steel pipe 3, U-shaped steel
4th, dowel 5, are made of inside the cylinder 1 square steel tube 2, round steel pipe 3, U-shaped steel 4, dowel 5, outside the cylinder 1
Portion's casting concrete 6,3 both ends of round steel pipe set square steel tube 2, are connected between the round steel pipe 3 by dowel 5
Connect, connected between the square steel tube 2 by U-shaped steel 4.
Two sides of the U-shaped steel 4 set through hole 7.
The square steel tube 2,3 inside concrete perfusion 6 of round steel pipe.
The dowel 5 of 3 both sides of round steel pipe is set in X-type cross.
The utility model is when in use：A kind of multi-cavity steel tube concrete column, including it is cylinder, square steel tube, round steel pipe, U-shaped
The steel structure framework of steel, dowel, square steel tube and round steel pipe composition column body, the both ends of each round steel pipe pass through respectively
Welding manner sets two square steel tubes, is connected between adjacent circular steel pipe by dowel, and the dowel of round steel pipe both sides
Set in X-type cross；Connected between adjacent square steel tube by U-shaped steel, and in order not to stay perfusion dead angle, in two sides of U-shaped steel
Face sets through hole, easy to filling concrete.After the square steel tube of column body connects fixation with round steel pipe, in square steel tube and circle
The outer formwork supporting plate of shape steel pipe, then concrete perfusion.
Generally, the utility model has the advantages that filling concrete convenience, high capacity, shear behavior are good.
