Abstract
The utility model relates to a reinforced type rectangular steel tube, which comprises the rectangular steel tube. The reinforced type rectangular steel tube is characterized in that a pair of side edges of the cross section of the rectangular steel tube are inner concave edges. The reinforced type rectangular steel tube has the advantage that the lateral stiffness of the rectangular steel tube can be enlarged to satisfy operating requirements in a large span structure.
Description
Technical field
The utility model relates to a kind of steel pipe, particularly a kind of reinforced rectangular steel pipe.
Background technology
Steel pipe is widely used in the industrial and agricultural production at present, particularly use steel pipe in a large number in the building industry of machine-building, automobile framework, storage rack, lightweight steel construction, because the requirement on using is more and more higher, existing ordinary rectangular steel pipe transverse rigidity is relatively poor, can't satisfy instructions for use when using in longspan structure.
Summary of the invention
The purpose of this utility model provides a kind of reinforced rectangular steel pipe, and is relatively poor to solve ordinary rectangular steel pipe transverse rigidity, can't satisfy the problem of instructions for use when using in longspan structure.The utility model designs reinforced rectangular steel pipe, comprises rectangular steel pipe, it is characterized in that: an opposite side of the cross section of rectangular steel pipe is interior concave edge.The utility model has the advantages that and to strengthen the rectangular steel pipe lateral stiffness, satisfy the instructions for use in longspan structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated, accompanying drawing is a structural representation of the present utility model,
Comprise rectangular steel pipe 1 among the specific embodiment figure, it is characterized in that: an opposite side 2 of the cross section of rectangular steel pipe 1 is interior concave edge, because the side 2 of rectangular steel pipe 1 is interior concave edge, therefore has bigger lateral stiffness, general steel pipe can satisfy the instructions for use in longspan structure.
Claims (1)
- Reinforced rectangular steel pipe comprises rectangular steel pipe, it is characterized in that: an opposite side of the cross section of rectangular steel pipe is interior concave edge.
