Contining function, itself also can largely improve the compressive property of structure；Ribbed stiffener along steel pipe central axis direction every
Suitable distance is fixed on steel pipe inner wall, can improve the contining function of structure, prevent outer steel pipe flexing, and can avoids using template
To fix i shaped steel bone post, cost-effective；In addition, peg is provided with steel pipe inner wall can also effectively prevent steel tube concrete
The de- of soil sticks.
Further, floor is provided with evenly distributed first through hole in the middle part of the I-shaped reinforced concrete column.
Beneficial effect using above-mentioned further scheme is：It is by first through hole that concrete and I-shaped reinforced concrete column is steady
It is solidly connected, is not susceptible to de- glutinous, enhancing structure intensity.
Further, the ribbed stiffener is screw-thread steel.
Beneficial effect using above-mentioned further scheme is：Screw-thread steel is common building material, and its acquisition modes is simple,
Cost is low, beneficial to the cost for reducing total.
Further, the ribbed stiffener is platy structure, and the ribbed stiffener is provided with the second evenly distributed through hole.
Beneficial effect using above-mentioned further scheme is：Ribbed stiffener is provided with evenly distributed through hole, and concrete can
To be preferably fixedly connected with ribbed stiffener, make structure more reliable.
Further, the peg is in quincuncial arrangement in the steel pipe inner wall.
Beneficial effect using above-mentioned further scheme is：The peg is in quincuncial arrangement in the steel pipe inner wall.
Beneficial effect using above-mentioned further scheme is：Peg is more traditional in quincuncial arrangement in the steel pipe inner wall
Proper alignment can more save material to peg side by side.
Further, the steel tube section is ellipse, nose circle shape, rectangle or circle.
Beneficial effect using above-mentioned further scheme is：This programme is applied to multiple section and steel pipe, use range
Extensively.
Due to being had the advantages that using above-mentioned technical proposal, the utility model：
1. steel pipe is divided into different zones by the utility model by ribbed stiffener and I-shaped reinforced concrete column, the tight of structure is improved
