Embodiment 1

[0019] Such as figure 1 Shown is a corrugated steel plate confined concrete composite column. The composite column is formed by welding four corrugated steel plates 1 and four steel pipes 2 with a square cross section to form a quadrilateral pipe, wherein the four steel pipes 2 with a square cross section are located at the four vertices of the quadrilateral, and then between the quadrilateral pipe and the four square ( Or rectangular) steel pipe 2 is filled with concrete 3 and formed.

[0020] Its production method is as follows:

[0021] 1) Process corrugated steel plate 1 and square steel pipe 2 according to the designed size;

[0022] 2) A square steel pipe 2 is used as a corner and a corrugated steel plate 1 is welded to form a quadrilateral pipe, and the corrugated direction of the corrugated steel plate 1 is the same as the length direction of the quadrilateral pipe;

[0023] 3) Fill the concrete 3 in the quadrilateral pipe and the corner square steel pipe 1 .

Embodiment 2

[0025] Such as figure 2 Shown is another corrugated steel plate confined concrete composite column. The composite column is formed by welding four corrugated steel plates 1 and four circular steel pipes 2 to form a quadrilateral pipe, wherein the four circular steel pipes 2 are located at the four vertices (i.e. corners) of the quadrilateral, and then the quadrilateral pipe and the four The circular steel pipe 2 is filled with concrete 3 and formed. Its production method is as follows:

[0026] 1) Process the corrugated steel plate 1 and the circular steel pipe 2 according to the designed size;

[0027] 2) The circular steel pipe 2 is used as the corner and the corrugated steel plate 1 is welded to form a quadrilateral pipe, and the corrugated direction of the corrugated steel plate 1 is the same as the length direction of the quadrilateral pipe;

[0028] 3) Concrete 3 is filled in the square pipe and the round steel pipe 1 at the corner.

Embodiment 3

[0030] Such as image 3 Shown is another corrugated steel plate confined concrete composite column. The composite column is composed of three corrugated steel plates 1 and three circular steel pipes 2 welded to form a triangular pipe, wherein the three circular steel pipes 2 are located at the three vertices of the triangle, and then the triangular pipe and the Three circular steel pipes 2 are filled with concrete 3 to form. Its production method is as follows:

[0031] 4) Process the corrugated steel plate 1 and the circular steel pipe 2 according to the designed size;

[0032] 5) The round steel pipe 2 is used as the corner and the corrugated steel plate 1 is welded to form a triangular pipe, and the corrugated steel plate 1 has the same corrugated direction as the length direction of the triangular pipe;

[0033] 6) Concrete 3 is filled in the triangular pipe and the round steel pipe 1 at the corner.

Abstract

The invention discloses a corrugated steel plate confined concrete combination column which is a polygon tube formed by using a plurality of corrugated steel plates and a plurality of steel tubes as turning corners, wherein the corrugation directions of the corrugated steel plates are identical to the length direction of the polygon tube; and concrete is further filled into the polygon tube and the corners so as to manufacture the combination column. In addition to the excellent mechanical property of the conventional steel tube concrete, the combination column further has the following remarkable advantages that the load born by corrugated steel plate bears in the corrugation direction is small, so that the strength of the corrugated steel plate is mainly for providing annular restraint on the core concrete, then the compression bearing capacity of the core concrete is greatly improved, the compression bearing capacity of the combination column is improved to a large extent, the material is saved, and the engineering cost is reduced; the outer rigidity of the plane of the corrugated steel plate is large, and the corrugated steel plate is unlikely to bulge under the transverse expansion deformation action of the core concrete, so that the effective annual restraint of the corrugated steel plate to the core concrete is increased, and the compression bearing capacity of the combination column is further improved.

Description

technical field [0001] The invention relates to a form of building components, in particular to a corrugated steel plate confined concrete composite column applied in the field of civil engineering and a manufacturing method thereof. Background technique [0002] Confined steel tube concrete columns, that is, concrete-filled steel tube columns, refer to composite structural members formed by filling concrete in steel tube cavities. The basic principles are as follows: 1) The core concrete is in a three-dimensional compression state by using the confinement effect of the steel pipe on the concrete filled inside the steel pipe, so that the core concrete has a higher compressive strength and compression deformation capacity; 2) With the help of the internal concrete The supporting function of the steel pipe can enhance the geometric stability of the steel pipe wall and change the instability mode of the hollow steel pipe, thereby improving the compressive bearing capacity of th...
