Technical field
The utility model relates to field of civil engineering, specifically is a kind of steel core concrete column.
Background technology
Steel core concrete column is the member that is combined by fill concrete in the steel pipe, can bring into play steel pipe and concrete advantage, is a kind of basic building block in the civil engineering, and is circular, square and the polygonal cross-section member is comparatively commonly used; Wherein comparatively regular than the concrete profile of circular stainless steel because of the profile of square stainless steel tube concrete post, bending rigidity is big and have the advantage of being convenient to node processing, and then the application of square steel tube concrete column is comparatively extensive in practical applications.Yet; The rectangular steel tube of square steel tube concrete column is not so good as the round steel pipe concrete column to the effect of contraction of concrete filler; Be prone to cause the anti-crack ability of steel pipe walls flexing, concrete filler, anti-contractility to be affected, thereby make the anti-crack ability of square steel tube concrete column, anti-contractility and ductility relatively poor.
Because stainless steel tube has beautiful outward appearance and good corrosion-resistant property, more and more receives people's attention, though in some venue buildings, use, its fancy price still lets the people step back.
In view of above-mentioned reason, the defective of inventor's square shaped steel core concrete column and stainless steel tube is furtherd investigate, and is then produced by this case.
The utility model content
The purpose of the utility model provides a kind of stainless steel composite pipe concrete column, and it has stainless aesthetic appearances and good corrosion-resistant property, and cost of manufacture is low; And can avoid the anti-crack ability of traditional square steel core concrete column, anti-contractility and the relatively poor problem of ductility.
The technical scheme of the utility model is: a kind of stainless steel composite pipe concrete column; Comprise steel pipe column and concrete filler; Also comprise the circular steel tubing string; Above-mentioned steel pipe column is square stainless-steel pipe post, and above-mentioned round steel pipe column sleeve is located in the above-mentioned square stainless-steel pipe post, and above-mentioned concrete filler comprises the first concrete filler and the second concrete filler; Filling in the above-mentioned circular steel tubing string has the above-mentioned first concrete filler, and filling between above-mentioned circular steel tubing string and the above-mentioned square stainless-steel pipe post has the above-mentioned second concrete filler.
The end face of above-mentioned square stainless-steel pipe post, above-mentioned circular steel tubing string, the above-mentioned first concrete filler and the above-mentioned second concrete filler all flushes, and the axial line of the axial line of above-mentioned square stainless-steel pipe post and above-mentioned circular steel tubing string coincides.
The body of above-mentioned circular steel tubing string for processing by common iron or high-strength steel, and above-mentioned circular steel tubing string is the thin-wall steel tube of 20-150 for the long ratio with thickness of pipe wall of its steel.
Offer the even axially extending bore chain spaced apart of circumferencial direction of some the above-mentioned circular steel tubing strings in edge on the tube wall of above-mentioned circular steel tubing string; Each above-mentioned axially extending bore chain serve as reasons several evenly through holes spaced apart combine, and each above-mentioned through hole of above-mentioned axially extending bore chain is provided with along the axial direction coiled coil of above-mentioned circular steel tubing string.
Spacing between the above-mentioned in twos through hole on the above-mentioned axially extending bore chain is not less than the twice of this through-hole aperture, and the quantity that above-mentioned circular steel tubing string is positioned at the above-mentioned through hole on the same cross-section location is not more than 3.
A kind of stainless steel composite pipe concrete column of the utility model; Because steel pipe column is square stainless-steel pipe post; Make steel pipe column have graceful structure outward appearance and good corrosion-resistant property; Can save anticorrosion, the antirust treatment process in steel pipe column later stage, and the structure of steel pipe column is square, has the advantages that bending resistance is strong, be convenient to node processing; Simultaneously, be arranged with a circular steel tubing string in the steel pipe column, make the bearing capacity of steel core concrete column stronger; Steel pipe column can adopt the thin stainless-steel pipe of wall thickness like this, compares with traditional stainless-steel pipe concrete column, can practice thrift stainless engineering consumption greatly; Cost of manufacture is lower; And utilize the circular steel tubing string that the concrete filler is had effect of contraction preferably, make the concrete filler can give full play to its effect, thereby make the anti-crack ability of concrete filler, anti-contractility be difficult for being affected; The premium properties of concrete filler can be not fully exerted, can improve the shear resistance of stainless steel tube concrete post greatly; And when fire takes place, utilize the second concrete filler can effectively delay outside heat, can improve the fire resistance of stainless steel tube concrete post greatly to the transmission of circular steel tubing string.Again owing to offer some the even axially extending bore chains spaced apart of the circumferencial direction along the circular steel tubing string on the tube wall of circular steel tubing string; Each axially extending bore chain serve as reasons several evenly through holes spaced apart combine; And each through hole of axially extending bore chain is provided with along the axial direction coiled coil of circular steel tubing string; The concrete filler that can be communicated with side inside and outside the circular steel tubing string like this through the through hole on each axially extending bore chain; Strengthened in the first concrete filler and the circular steel tubing string second concrete filler outward in the circular steel tubing string exchange of moisture be connected; Reduce the contraction of concrete filler, can save the water seasoning operation, simplified the maintaining process of concrete filler.

The specific embodiment
A kind of stainless steel composite pipe concrete column of the utility model; Like Fig. 1,2, shown in 3; Comprise steel pipe column 1, circular steel tubing string 2 and concrete filler 3; This steel pipe column 1 is square stainless-steel pipe post, the body of this circular steel tubing string 2 for processing by common iron or high-strength steel, and the ratio that this circular steel tubing string 2 is its pipe range and thickness of pipe wall is the thin-wall steel tube of 20-150; This circular steel tubing string 2 is sheathed in the square bar tubing string 1; And the axial line of the axial line of circular steel tubing string 2 and square bar tubing string 1 coincides, and the end face of the end face of circular steel tubing string 2 and square bar tubing string 1 flushes, and offers some the even axially extending bore chains spaced apart of the circumferencial direction along circular steel tubing string 2 on the tube wall of this circular steel tubing string 2; Each axially extending bore chain serve as reasons several evenly through holes 21 spaced apart combine; The twice in not little these through hole 21 apertures of the spacing between two two through hole 21, and each through hole 21 of axially extending bore chain is provided with along the axial direction coiled coil of circular steel tubing string, and the quantity that circular steel tubing string 2 is positioned at the through hole 21 on the same cross-section location is not more than 3.
