A kind of strong constraint rectangular profile concrete filled steel tube rod structure with ribbing, including a rectangle load-bearing steel pipe, have poured in it
Concrete is forming steel core concrete column；
The middle part of each lateral wall of the rectangle load-bearing steel pipe caves inward to form a groove, the groove and rectangle load-bearing
Steel pipe is isometric and length direction parallel to steel core concrete column, and the cross section of the groove is arc, while the depth of the groove
10~14% of the width for respective outer wall are spent, width is the 85~90% of the width of corresponding lateral wall；
The floor for arranging at equal intervals successively up and down is equipped with each above-mentioned groove of the rectangle load-bearing steel pipe, with raising
The bending resistance under the lateral expansion power effect of the side wall of rectangle load-bearing steel pipe concrete wherein is stated, so as to improve rectangle hold
Weight steel pipe to the effect of contraction of concrete therein, the shape of the geomery of the floor and the cross section of corresponding above-mentioned groove
Shape size is identical, and adjacent two lateral wall of rectangle load-bearing steel pipe floor at grade, the neighbouring floor
The distance between for 1/4~1 times of width of corresponding lateral wall, the thickness of floor is the 1/3 of the thickness of corresponding lateral wall
~1 times.
In a preferred embodiment of the invention, the distance between neighbouring described floor is corresponding outside
1/3~1 times of the width of wall.
In a preferred embodiment of the invention, the thickness of the floor is the 1/2 of the thickness of corresponding lateral wall
~1 times.
In a preferred embodiment of the invention, the depth of the groove for respective outer wall width 10~
12.5%.
In a preferred embodiment of the invention, the width of the groove is the 87.5 of the width of corresponding lateral wall
~90%.
In a preferred embodiment of the invention, the cross section of the rectangle load-bearing steel pipe is shaped as square.
It is further preferred that the geomery of the groove of the adjacent two side of the rectangle load-bearing steel pipe is identical.
Beneficial effects of the present invention：Present invention strong constraint rectangular profile concrete filled steel tube rod structure with ribbing can not only play square
Advantage of the tee section on building arrangements, is both the restriction ability and steel that can significantly improve rectangle load-bearing steel pipe to wherein concrete
The local stability performance of pipe, improves the utilization ratio of material.
