Abstract

An impact resisting column assembly of train station is provided. The column assembly includes: a column ( 2 ); an encasing steel plate ( 8 ) wrapping about the column ( 2 ); a rigid jacket ( 3 ) having a rectangular cross-section, fitted over the encasing steel plate ( 8 ) and spaced apart from the encasing steel plate ( 8 ); and mild steel energy dissipators ( 7 ) disposed between a first side ( 81 ) of the encasing steel plate ( 8 ) and a first side ( 31 ) of the rigid jacket ( 3 ), and between a second side ( 82 ) of the encasing steel plate ( 8 ) and a second side ( 31 ) of the rigid jacket ( 3 ), in which the first and second sides ( 81, 82 ) are parallel with each other and perpendicular to an extension direction of a railway ( 1 ) in the train station, and the first and second sides ( 31, 32 ) are parallel with each other and perpendicular to the extension direction.

First claim

What is claimed is:

1. An impact resisting column assembly of a train station, comprising:
a column;
an encasing steel plate wrapping about the column;
a rigid jacket having a rectangular cross-section, fitted over the encasing steel plate and spaced apart from the encasing steel plate; and
mild steel energy dissipators disposed between a first side of the encasing steel plate and a first side of the rigid jacket, and between a second side of the encasing steel plate and a second side of the rigid jacket,
wherein the first and second sides of the encasing steel plate are parallel with each other and perpendicular to an extension direction of a railway in the train station, and the first and second sides of the rigid jacket are parallel with each other and perpendicular to the extension direction of the railway.

2. The column assembly of claim 1 , wherein the rigid jacket comprises:
an inner steel plate connected to the mild steel dissipators;
an outer steel plate disposed at an outside of the inner steel plate and spaced apart from the inner steel plate;
reinforcing ribs disposed between the inner steel plate and the outer steel plate.

3. The column assembly of claim 2 , wherein the inner steel plate, the outer steel plate and the reinforcing ribs are welded into one piece.

4. The column assembly of claim 1 , wherein a lower end of the encasing steel plate is extended downwardly to be adjacent to a bottom of the column.

5. The column assembly of claim 1 , wherein an upper end surface of the encasing steel plate is flush with that of the rigid jacket.

6. The column assembly of claim 1 , wherein a length of the rigid jacket ranges from 1.5 m to 2.5 m.

7. The column assembly of claim 6 , wherein a height from a center of the rigid jacket in a vertical direction to a horizontal plane in which the railway is located ranges from 1 m to 2 m.

8. The column assembly of claim 7 , wherein a distance from a side of the rigid jacket parallel with the extension direction to a side of the encasing steel plate adjacent to the side of the rigid jacket ranges from 200 mm to 800 mm.

9. The column assembly of claim 1 , wherein the mild steel energy dissipators are connected with each other in a horizontal direction.

10. The column assembly of claim 9 , wherein the mild steel energy dissipators are arranged into a plurality of rows spaced apart from one another in a vertical direction.

11. The column assembly of claim 2 , wherein a lower end of the encasing steel plate is extended downwardly to be adjacent to a bottom of the column.

12. The column assembly of claim 2 , wherein an upper end surface of the encasing steel plate is flush with that of the rigid jacket.

13. The column assembly of claim 2 , wherein a length of the rigid jacket ranges from 1.5 m to 2.5 m.

14. The column assembly of claim 13 , wherein a height from a center of the rigid jacket in a vertical direction to a horizontal plane in which the railway is located ranges from 1 m to 2 m.

15. The column assembly of claim 14 , wherein a distance from a side of the rigid jacket parallel with the extension direction to a side of the encasing steel plate adjacent to the side of the rigid jacket ranges from 200 mm to 800 mm.

16. The column assembly of claim 2 , wherein the mild steel energy dissipators are connected with each other in a horizontal direction.

17. The column assembly of claim 16 , wherein the mild steel energy dissipators are arranged into a plurality of rows spaced apart from one another in a vertical direction.
