Novel steel pipe concrete pole
1999
The utility model discloses a novel steel pipe concrete column. A steel pipe for filling concrete is a profiled thin wall steel pipe, and each side of the profiled thin wall steel pipe is provided with a constraining pull rod. The profiled thin wall steel pipe of the utility model can be a thin wall steel pipe in a square shape, an L shape or a T shape. The minimal side length of the profiled thin wall steel pipe is larger than or equal to 150MM, and the wall thickness is larger than or equal to 8MM. The spacing of every two constraining pull rods is 100MM to 200MM; the slenderness ratio of the column (the width ratio of the length to the minimum section) is less than or equal to 30. The structures of the column and the node of utility model are simple with economical and convenient construction, and the building plane requirements are easy to conform. The utility model has the advantages of high bearing capacity, large toughness, light weight, good plasticity, good toughness, good impact resistance, good fatigue resistance property, good shock resistance, etc.
