In order to achieve the above purpose, the technical scheme of the utility model is as follows:

the utility model provides a steel-pipe column and concrete column coincide connected node, includes concrete column, steel pipe, inside the steel pipe inserts concrete column, the steel pipe lower limb is equipped with the bottom plate that turns up, the bottom plate that turns up passes through the crab-bolt with concrete column and is connected, the inside outer wall welding peg of steel pipe, the inside vertical inboard owner muscle that is equipped with of steel pipe, be equipped with interior stirrup on the inboard owner muscle, be equipped with outer main muscle in the concrete column outside the steel pipe, inboard owner muscle and outer main muscle down extend to the concrete column in, set up the built-up muscle between the outer peg crack of steel pipe, the built-up muscle passes through the lacing wire tie with outer main muscle, and the outer outside stirrup of steel pipe sets up with steel pipe coincide partial concrete column top and encrypts the stirrup, and the inside and outside of steel pipe is filled.

As an improvement of the utility model, the steel pipe inserts perpendicularly inside the concrete column.

As an improvement of the utility model, 3/4 height inserts in the concrete column below the steel pipe.

As an improvement of the utility model, the steel pipe is a square pipe or a round pipe.

As an improvement of the present invention, the number of the anchor bolts is four.

The utility model has the advantages that:

a steel-pipe column and concrete column coincide connected node, adopt the steel-pipe column to be connected with concrete column coincide's mode, the steel-pipe column most is vertical inserts the concrete column in-connection and becomes whole, saved steel greatly, connected node passes power directness, connects safe and reliable, the practicality is strong.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings and embodiments, which are to be understood as illustrative only and not limiting the scope of the invention. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

As shown in the figure, the utility model discloses mainly used steel-pipe column (square tubular column or round tubular column) and concrete column's connection structure. The connection mode is as follows:

(1) the concrete column 5 is poured to the bottom elevation of the downward turning bottom plate 2 below the steel pipe at one time, the temporary positioning anchor bolt 3 of the steel pipe 1 is pre-embedded in advance, the main reinforcement 7 on the inner side of the steel pipe is pre-inserted in advance, the inner stirrup 9 is bound, and the main reinforcement 6 on the outer side of the concrete column extends upwards;

(2) the steel pipe 1 is manufactured in a factory, a column base is welded with a downward-turning bottom plate 2 with a narrow edge, and studs 4 are welded on the inner wall and the outer wall of the steel pipe;

(3) the on-site hoisting steel tube 1 penetrates through the space between the outer main reinforcement 6 and the inner main reinforcement 7 to the head of the concrete column 5, and is positioned and temporarily fixed through a downward turning anchor bolt 3;

(4) erecting ribs 11 are arranged between gaps of the studs 3 on the outer side of the steel pipe 1, the erecting ribs 11 are tied with outer main ribs 6 extending above the concrete column through tie bars 12, outer stirrups 10 of the superposed part of the steel column are bound, and the top end of the concrete column 5 of the superposed part of the steel pipe 1 is provided with a strengthening stirrup 8;

(5) the concrete column template of the superposition part is erected conventionally;

(6) firstly, pouring concrete 13 on the inner side of the steel pipe column, and then pouring concrete 14 on the outer side of the steel pipe column.

The utility model discloses steel-pipe column and concrete column's connected node is connected through the mode of steel-pipe column and concrete column coincide, set up the bottom plate earlier at the steel-pipe column base, set up a small amount of construction location crab-bolt, steel column and the inside and outside welding toggle bolt of concrete column coincide part pipe wall, stretch on the main muscle in the concrete column outside, the main muscle is add to steel-pipe column inboard, concrete column outside coincide part top stirrup encrypts simultaneously, it erects the muscle to assist again, the lacing wire, it is reliable just to have formed to pass power, connect reliable steel-pipe column and concrete column coincide connected node.

The technical means disclosed by the scheme of the present invention is not limited to the technical means disclosed by the above embodiments, but also includes the technical scheme formed by the arbitrary combination of the above technical features.
