Steel core concrete column is suitable for building arrangements, improves space efficiency utilization, therefore be widely used in Practical Project.With building
The increase of height, the sectional dimension of vertical supporting member are consequently increased, and so as to reduce the usable floor area of building, are reduced and are built
The economic benefit built.High-strength concrete is used in the vertical supporting member of high building structure be to reduce vertical supporting member to cut
One important technical of face size, but high-strength concrete ductility is poor, and rectangular steel pipe can not provide foot to high-strength concrete
Enough effect of contractions, this largely constrains application of the rectangular steel pipe high-strength concrete column in Practical Project.
Utility model content
The purpose of this utility model is to overcome prior art defect, there is provided one kind combination constraint rectangular steel-tube concrete column
Structure.

Embodiment
The technical solution of the utility model is further detailed below by way of embodiment combination accompanying drawing and
Description.
Embodiment 1
As shown in Figure 1 and Figure 4, a kind of combination constraint rectangular steel-tube concrete column structure, including the He of a rectangle load-bearing steel pipe 1
At least one constraint steel pipe 2；The rectangle load-bearing steel pipe 1 has an at least plastic region, has poured concrete 3 to form steel pipe in it
Concrete column；At least one constraint steel pipe 2 is set in outside an at least plastic region for the steel core concrete column；At least one constraint
Gravity flowing levelling mortar 4 has been poured between steel pipe 2 and rectangle load-bearing steel pipe 1；Lead between the gravity flowing levelling mortar 4 and rectangle load-bearing steel pipe 1
The butyl rubber buildings waterproof sealant tape 5 (soft isolated material) for crossing the outer wall of a wrapping rectangle load-bearing steel pipe 1 is separated by, with
The interface shear stress transmission between rectangle load-bearing steel pipe 1 and constraint steel pipe 2 is eliminated, ensures that above-mentioned constraint steel pipe 2 plays lateral confinement
Effect, without directly participation bearing load, so that it is guaranteed that the binding effect of above-mentioned constraint steel pipe 2 and preventing the concrete filled steel tube
The transfer of the plastic region of post.
As shown in figure 3, the madial wall of the constraint steel pipe 2 has decorative pattern 20, to improve constraint steel pipe 2 and the Self-leveling
Interface shearing strength between mortar 4.
Specifically, the 1~2 of the length of longest edge of the length of the constraint steel pipe 2 for the cross section of rectangle load-bearing steel pipe 1
Times.The length of side of the cross section of the constraint steel pipe 2 is 1.1~1.3 times of the length of side of corresponding rectangle load-bearing steel pipe 1.It is described about
The thickness of Shu Gangguan 2 side wall is 0.5~1 times of the thickness of the side wall of the rectangle load-bearing steel pipe 1.
Specific preparation method of the present utility model is as follows：
As depicted in figs. 1 and 2, the making of rectangle load-bearing steel pipe 1 and in place at the scene is first completed；
Secondly, the i section steel beam 6 with peg 60 is welded in the left and right sides of rectangle load-bearing steel pipe 1.I section steel beam 6
The position of welding is determined according to floor height, and distance of the peg 60 away from the end of i section steel beam 6 arrives butyl rubber for the inner side of constraint steel pipe 2
The 1/2 of the distance between glue buildings waterproof sealant tape 5.
Then, started respectively at the both ends of rectangle load-bearing steel pipe 1 with butyl rubber buildings waterproof sealant tape 5 toward mid-wrap
Go out two separation layers, then, two pieces of sides are smooth, channel-section steel of the side with decorative pattern 20 is welded into constraint after styletable fixes
Steel pipe 2, the side of channel-section steel decorative pattern 20 are the inner side of constraint steel pipe 2.Constraint steel pipe 2 positioned at the lower end of i section steel beam 6, its lower end also need
Welding steel seals, and the left and right sides needs reserving hole to irrigate gravity flowing levelling mortar 4.Similarly, others are sequentially completed about
Shu Gangguan 2 construction.
Finally, toward casting concrete 3 in rectangle load-bearing steel pipe 11, Self-leveling is poured into toward between constraint steel pipe 2 and separation layer
Mortar 4.After the intensity of concrete 3 reaches requirement.
It is described above, preferred embodiment only of the present utility model, therefore the utility model implementation can not be limited according to this
