Embodiment 1

[0027] Such as figure 2 As shown, this embodiment takes the "T-shaped" short-leg shear wall as an example.

[0028] The T-shaped short-leg shear wall includes a square steel tube column 1, a steel plate 2, and a steel cage 3. Among them, the three ends of the short-leg shear wall and the middle corners are all equipped with steel pipe columns 1. The steel pipe columns 1 at the ends form end columns, and the steel pipe columns 1 at the middle corners form dark columns; six steel plates 2 Divided into three groups, each group includes two steel plates 2, respectively connecting the ends of the short-leg shear wall and the two steel pipe columns 1 at the corners; the steel plates 2 are arranged symmetrically, and the outer surface of the steel plate 2 is connected to the connected steel pipe column 1 The end faces of the steel plate are flush, and the steel plate 2 and the steel pipe column 1 are fixedly connected by welding. The welding process can be welded by industrial robots t...

Embodiment 2

[0037] Such as Figure 4 As shown, this embodiment takes the "L-shaped" short-leg shear wall as an example.

[0038] The L-shaped short-leg shear wall includes a square steel tube column 1, a steel plate 2, and a steel cage 3. Among them, the two ends of the short-leg shear wall and the corners in the middle are equipped with steel pipe columns 1, the steel pipe columns 1 at the ends form end columns, and the steel pipe columns 1 at the middle corners form dark columns; four steel plates 2 Divided into two groups, each group includes two steel plates 2, respectively connecting the ends of the short-leg shear wall and the two steel pipe columns 1 at the corners; the steel plates 2 are arranged symmetrically, and the steel plates 2 are flush with the ends of the connected steel pipe columns 1 The steel plate 2 is connected to the steel pipe column 1 by welding. A pre-bound steel cage 3 is placed in the cavity formed between the steel plate 2 and the steel pipe column 1. The steel ...

Embodiment 3

[0045] Such as Image 6 As shown, this embodiment takes the "cross-shaped" short-leg shear wall as an example.

[0046] The cross-shaped short-leg shear wall includes a square steel tube column 1, a steel plate 2, and a steel cage 3. Among them, the four ends of the short-leg shear wall and the middle corners are equipped with steel pipe columns 1, the steel pipe columns 1 at the ends form end columns, and the steel pipe columns 1 at the middle corners form dark columns; eight steel plates 2 Divided into four groups, each group includes two steel plates 2, respectively connecting the ends of the short-leg shear wall and the two steel pipe columns 1 at the corners; the steel plates 2 are arranged symmetrically, and the steel plates 2 are flush with the two ends of the connected steel pipe columns , And the steel plate 2 and the steel pipe column 1 are fixedly connected by welding. The pre-bound steel cage 3 is placed in the cavity formed between the steel plate 2 and the steel pi...

Abstract

The invention discloses a steel-concrete combined short-leg shear wall. Steel tube columns are arranged on the end and the corner of the short-leg shear wall. Steel plates are symmetrically arranged between the adjacent steel tube columns on the short-leg shear wall, the two ends of the steel plates are fixedly connected with the steel tube columns, and interiors of the steel tube columns and a cavity formed between the steel plates and the steel tube columns are filled with concrete. The shear wall is simple in structural manner, industrial production is facilitated, the manner of combining steel tubes, the steel plates and concrete is adopted, the structural rigidity can be improved, the anti-seismic property is improved, the use amount of the steel tubes is small, and economy is good.

Description

Technical field [0001] The invention relates to a short-leg shear wall, in particular to a steel-concrete combined short-leg shear wall. Background technique [0002] At present, a short-leg shear wall refers to a shear wall with a section thickness not greater than 300mm, and the ratio of section height to thickness greater than 4 but not greater than 8. Most of the existing short-leg shear walls are cast-in-place reinforced concrete structures or steel tube bundle composite structures. During the construction of the traditional cast-in-situ reinforced concrete short-leg shear wall structure, the length of the steel bar blanking is determined according to the drawings and the steel bars are tied, and then formwork support is performed, and then the concrete is poured. During construction, a template is arranged around the wall, and after it is in place, it is fixed by tension bolts. This construction method requires precise alignment of the tie bolts, and a large number of tie...
