Abstract

The invention relates to a spiral-stirrup square steel tube concrete column comprising a square steel tube, a spiral stirrup and concrete. The spiral-stirrup square steel tube concrete column is characterized in that the square steel tube is connected with the spiral stirrup by spot welding to form a spiral-stirrup square steel tube, and the concrete is directly cast into the spiral-stirrup square steel tube. The spiral-stirrup square steel tube concrete column integrates the advantages of a square steel tube concrete column and a round steel tube concrete column and has the advantages of simple node, convenience in processing, short construction period, convenience in the adotpion of fire-prevention plates and the like because the outer part of the spiral-stirrup square steel tube concrete column is the square steel tube; and because the spiral stirrup is arranged in the spiral-stirrup square steel tube concrete column, the restraining capacity of the square steel tube on the core concrete is enhanced so that the bearing capacity of the steel tube concrete column is increased, and the area of a column section is reduced. The spiral-stirrup square steel tube concrete column has simple production process and high production efficiency and is especially suitable for the structures of high-rise buildings.

Description

A kind of spiral stirrup concrete-filled steel square tubular column and preparation method thereof

Technical field

The present invention relates to concrete-filled steel square tubular column, particularly, relate to a kind of spiral stirrup concrete-filled steel square tubular column and preparation method thereof.

Background technology

Along with the development of highrise building, the form of structure of steel core concrete column in the combining structure-H section steel beam is adopted by more and more building structure.The section form of the more steel core concrete column of using has round steel pipe cross section and square steel pipe cross section now.

Along with in application in engineering, this form of structure also shows some self advantage and deficiency gradually, mainly shows the following aspects:

1, the form of structure of concrete-filled steel square tubular column-H section steel beam has that node is simple, easy to process, short construction period, is convenient to adopt advantages such as fire-proof board, and its special advantages is arranged in highrise building; But square steel pipe to concrete restriction ability than round steel pipe a little less than, the existing theory of computation thinks that the concrete bearing capacity of square steel pipe is the simple superposition of two kinds of material bearing capacities, ignores square steel pipe to concrete cuff effect.

2, round steel pipe is strong to concrete effect of contraction in the form of structure of concrete-filled circular steel tube column-H section steel beam, can improve concrete actual compressive strength, thereby have the advantage that significantly improves its bearing capacity, make complexity, be unfavorable for that architectural effect realizes, is connected with building board shortcomings such as difficulty but this form of structure has node.

Therefore it is extremely urgent to need to seek a kind of form with both advantages.

Summary of the invention

In order to overcome deficiency of the prior art, the invention provides a kind of spiral stirrup concrete-filled steel square tubular column and preparation method thereof.

Technical scheme of the present invention is as follows:

A kind of spiral stirrup concrete-filled steel square tubular column comprises square steel pipe, spiral stirrup and concrete; It is characterized in that: square steel pipe is connected by spot welding with spiral stirrup, forms the spiral stirrup square steel pipe, and concrete directly pours in the spiral stirrup square steel pipe.

Preferably, square steel pipe is clod wash square steel pipe or square welded steel pipe;

Preferably, spiral stirrup is by the reinforcing bar spiralization;

Preferably, the external diameter of spiral stirrup and square steel pipe inner edge appearance etc.;

Spiral stirrup concrete-filled steel square tubular column preparation method is characterized in that: spiral stirrup is put into square steel pipe, carry out spot welding at the two ends and the square steel pipe of spiral stirrup, form the spiral stirrup square steel pipe.The spiral stirrup square steel pipe is upright, fluid concrete, and maintenance forms the spiral stirrup concrete-filled steel square tubular column after 28 days.

The invention has the beneficial effects as follows the advantage that combines concrete-filled steel square tubular column and concrete-filled circular steel tube column, the outside is a square steel pipe, has that node is simple, easy to process, short construction period, is convenient to take advantages such as fire-proof board; Inside is furnished with spiral stirrup, makes square steel pipe strengthen the restriction ability of core concrete, has increased the bearing capacity of steel core concrete column, has reduced the area of column section.And production technology is simple, and the production efficiency height is particularly suitable for using in high building structure.
