Abstract
A combined structure of the combined bundle of columns in the column includes a plurality of main steel bars, a one-drawing consecutive stirrup, and a plurality of tie bars. The plural main steel bars are arrayed to form an inner confined region and an outer confined region surrounding the inner confined region. Further, the one-drawing consecutive stirrup proceeds with a one-drawing consecutive turning and surrounding along the inner confined region and the outer confined region, and surrounds a region in the one-drawing consecutive stirrup of the inner confined region so as to form a column core. As such, a complete confinement can be provided for the main steel bars, so as to effectively prevent the main steel bars from buckling, such that the performance of seismic resistance for the columns can be enhanced.

The plural main steel bars 1 are arrayed to form an inner confined region 2 and an outer confined region 3 surrounding the inner confined region2. Further, the one-drawing consecutive stirrup 4 proceeds with a one-drawing consecutive turning and surrounding along the inner confined region 2 and the outer confined region 3. The one-drawing consecutive stirrup 4 surrounds every main steel bar 1, and surrounds a region in the one-drawing consecutive stirrup 4 of the inner confined region 2 so as to form a column core, wherein the one-drawing consecutive stirrup 4 and the plural main steel bars 1 are tied up together by winding plural metal wire. The plural tie bars 51 are each connected in between the plural main steel bars 1 in the inner confined region 2 and the outer confined region 3. The tie bars 51 each include a first end 511 and a second end 512, where the first end 511 hooks one of the plural main steel bars 511, which lacks lateral support, in the outer confined region 3, while the second end 512 anchors in the column core, where the column core refers to the region formed by the one-drawing consecutive stirrup 4 surrounding the inner confined region 2.
[0036] In the first embodiment, the first ends 511 of the tie bars 51 which hook the main steel bars 511 in the outer confined region 3, are each formed as a hook of about 180°. The second ends 512 of the tie bars 51, which anchor in the inner confined region 2, are each formed as a hook of about 90°. The two tie bars 51, which anchor in the inner confined region 2, are arranged in a manner of overlapping joining. Further, both the inner confined region 2 and the outer confined region 3 are in the form of square; or both are in the form of rectangle; or one of them is of square while the other is of rectangle.

[0043] Given the above, it is understood that all the embodiments, as mentioned above, not only can effectively enhance axial tension and pressure intensity of the column core, but also can provide a complete confinement for the main steel bars, so as to effectively prevent the main steel bars from buckling, and to decrease the decay of the strength and stiffness of the columns as subject to great axial force and repeated displacement, such that the performance of seismic resistance for the columns can be enhanced. Besides, in all the above-mentioned embodiments, the tie bars can be arranged, in a manner of overlapping joining or non-overlapping joining, in the combined structure of the combined bundle of columns in the column, or arranged in various angles in the combined structure of the combined bundle of columns in the column. This not only makes the construction easier, but also increases flexibility of arrangement without being adversely affected by the deviation of main steel bars at the site.
[0044] Although the present invention has been explained in relation to its preferred embodiments, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the invention as hereinafter claimed.
