Abstract

The utility model relates to a light-duty steel tube-concrete column. The utility model characters in the steel tube, inside of which is infused with concrete, and in the longitudinal reinforcing ribs that are distributing on the tube surface and parallel with the steel tube's axis. The utility model has such advantages as saving steel, great carrying capacity and reduction of jointing amount during manufacture.

Description

The light steel tube concrete column

Technical field

The utility model relates to a kind of light steel tube concrete column.

Background technology

Concrete filled steel tube is fill concrete and a kind of component form of forming in steel pipe.Concrete filled steel tube utilizes steel pipe and two kinds of material interactions when stressed of concrete, be that steel pipe is under the complex stress condition concrete to concrete effect of contraction, thereby concrete strength is improved, plasticity and toughness properties are greatly improved, simultaneously, because steel pipe generation cripling can be avoided or delay to concrete existence, can guarantee giving full play to of its material property.But adopt the thicker steel pipe of tube wall when the conventional steel concrete column is made usually, thereby it is more to expend steel, has the cost height, the welding job amount is big and from great shortcoming.

Summary of the invention

The purpose of this utility model is that a kind of light steel tube concrete column will be provided, and this product not only can be saved steel, and supporting capacity is big, and can reduce the welding job amount when making.

The utility model is characterised in that: have concrete steel pipe to constitute by internal casting, be laid with the vertical ribs that parallels with the steel pipe center line on the described steel pipe perisporium.

The utility model has the superperformance of steel core concrete column on the one hand, on the other hand owing to be laid with the vertical ribs that parallels with the steel pipe center line on the steel pipe perisporium, thereby has further strengthened the rigidity of steel pipe.

The specific embodiment

The utility model embodiment one is characterised in that: have concrete steel pipe 3 to constitute by internal casting, be laid with the vertical ribs 1 that parallels with the steel pipe center line on the described steel pipe perisporium.

Above-mentioned vertical ribs can be located on the inwall or outer wall of steel pipe.

In order to strengthen steel strength, be provided with on the cross section of steel pipe between steel pipe walls two side stringers to drawing short muscle 2.Described steel pipe cross section can be circular, square or rectangle.

In order to alleviate steel pipe weight, described steel pipe is made of welding thin-wall steel tube or light gauge cold-formed steel shape steel pipe.The concrete of described steel pipe internal casting is light weight concrete construction or ordinary concrete, and the light steel tube concrete column of this structure is because ribs improves the effect of tube wall stability, so still have bigger supporting capacity.

The remarkable advantage of the utility model embodiment is: one, adopt welding thin-wall steel tube or light gauge cold-formed steel shape steel pipe can save steel, reduce the workload of welding; Two, welding longitudinal stiffener and being provided with to drawing reinforcing bar can improve bearing of component and ductility; Three, adopt light weight concrete construction can alleviate dead load.

The utility model is novel, and is reasonable in design, and its market prospects are considerable.
