Description

A kind of high strength square steel pipe concrete column

Technical field

The utility model relates to construction engineering technical field, particularly relates to a kind of high strength square steel pipe concrete column.

Background technology

In building structure, concrete-filled steel square tubular column, owing to make use of the advantage that square steel pipe tensile strength is high and concrete crushing strength is high, has the many advantages such as intensity is high, rigidity large, plasticity good toughness.But easily there is cripling in the tube wall of square steel pipe, in order to limit its partial loop variation, usually adopt with the following method: one is the flakiness ratio limiting square steel pipe, two is in square steel pipe, arrange reinforcing bar ribs or steel plate stiffening rib or adopt binding bar, the former is under the condition that steel pipe width is certain, in order to meet flakiness ratio requirement, needing to increase thickness of steel pipe, causing steel using amount to increase; Construct complexity, cost of the latter is too high, does not meet the requirement of engineering reality.

Summary of the invention

The technical problem that the utility model mainly solves is to provide a kind of high strength square steel pipe concrete column, can solve the series of problems that existing concrete-filled steel square tubular column partial loop variation exists.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of high strength square steel pipe concrete column, comprising: square steel pipe, spiral stirrup, reinforcing bar and concrete; Described spiral stirrup is built in described square steel pipe center, described reinforcing bar is placed in described spiral stirrup, distance between described square steel pipe inwall and described spiral stirrup outer wall is greater than the distance between described spiral stirrup inwall and described reinforcing bar outer rim, and described concrete fills up the inner space of described square steel pipe.

In the utility model preferred embodiment, described reinforcing bar is star section.

In the utility model preferred embodiment, the distance between described square steel pipe inwall and described spiral stirrup outer wall is 35 ~ 45mm.

In the utility model preferred embodiment, described spiral stirrup inwall contacts with described reinforcing bar outer rim.

In the utility model preferred embodiment, described square steel pipe, spiral stirrup and reinforcing bar three are contour.

The beneficial effects of the utility model are: a kind of high strength square steel pipe concrete column of the utility model, structure is simple, reasonable in design, it is by built-in spiral stirrup and the reinforcing bar that contacts with spiral stirrup, significantly improve square steel pipe to concrete restraint performance, thus effectively preventing square steel pipe straight flange steel plate generation cripling, concrete-filled steel square tubular column of the present utility model has excellent supporting capacity, ductile performance and higher intensity, is the desirable tubing of building field.

Accompanying drawing explanation

Fig. 1 is the perspective view of a kind of high strength square steel pipe concrete column of the utility model;

Fig. 2 is the schematic top plan view of a kind of high strength square steel pipe concrete column of the utility model;

In accompanying drawing, the mark of each parts is as follows: 1. square steel pipe, 2. spiral stirrup, 3. reinforcing bar, 4. concrete.

Detailed description of the invention

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.

Refer to Fig. 1 and Fig. 2, the utility model embodiment comprises:

The utility model discloses a kind of high strength square steel pipe concrete column, comprises square steel pipe 1, spiral stirrup 2, reinforcing bar 3 and concrete 4, described square steel pipe 1, spiral stirrup 2 is identical with the height of reinforcing bar 3, described spiral stirrup 2 is built in the center of described square steel pipe 1, described reinforcing bar 3 is star section, be placed in described spiral stirrup 2, and the cross edge of stirrup 3 directly contacts with the inwall of described spiral stirrup 2, both mating reactions are complementary, further enhance concrete restraint forces, distance between described square steel pipe 1 inwall and described spiral stirrup 2 outer wall is 35 ~ 45mm, be greater than the distance between described spiral stirrup inwall and described reinforcing bar outer rim, concrete 4 fills up the inner space of square steel pipe 1.Spiral stirrup and reinforcing bar to concrete constraint, square steel pipe to concrete constraint, concrete between square steel pipe and spiral stirrup to the constraint of spiral stirrup, concrete between spiral stirrup and reinforcing bar is to the constraint of spiral stirrup, four synergies, enhance ductility and the bearing capacity of concrete-filled steel square tubular column, and effectively improve its anti-seismic performance.

Square steel pipe 1 described in the present embodiment can adopt Q235 steel and Q345 steel to make, and the HPB300 reinforcing bar cold bending that spiral stirrup 2 is 3 ~ 5mm by diameter processes, and described reinforcing bar is poured into a mould by Q390 steel and formed; Described concrete is high performance concrete.

Above-mentioned high strength square steel pipe concrete column, structure is simple, reasonable in design, it is by built-in spiral stirrup and the reinforcing bar that contacts with spiral stirrup, significantly improve square steel pipe to concrete restraint performance, thus effectively preventing square steel pipe straight flange steel plate generation cripling, concrete-filled steel square tubular column of the present utility model has excellent supporting capacity, ductile performance and higher intensity, is the desirable tubing of building field.

The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model manual and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
