Abstract
The utility model discloses a rectangular pipe, belonging to the field of cold-formed rectangular tube technology. The width height ratio of the rectangular pipe is from 1: 2.6 to 3.6. The utility model greatly improving the bearing capacity of the rectangular pipe, is suitable for vertical bearing structures such as a building, a bridge and steel structures.
Description
Technical field
The utility model relates to a kind of large-scale clod wash rectangular tube.
Background technique
Owing to be subjected to the restriction of shaped steel moulding process, cause the kind of rectangular tube more single, in general, the aspect ratio value minimum of rectangular tube is 1: 2.5, along with building, bridge and steel structure etc. have the occasion of specific (special) requirements to shaped steel, the bearing capacity of this rectangular tube often can not meet the demands.
The model utility content
Based on the defective of prior art, technical problem to be solved in the utility model is: the rectangular tube that provides a kind of variation by Aspect Ratio to cause bearing capacity to improve greatly.
The technical solution of the utility model is: a kind of rectangular tube, the ratio of the wide and height of described rectangular tube is 1: 2.6～3.6.
The ratio of the wide and height of described rectangular tube can be 1: 3.5, such as, can be so that the wide of described rectangular tube be 100mm, the height of rectangular tube is 350mm; Perhaps the ratio of the wide and height of described rectangular tube can be 1: 3, such as, can be so that the wide of rectangular tube be 150mm, the height of described rectangular tube is 450mm.
The beneficial effects of the utility model are: the bearing capacity that has improved rectangular tube greatly.
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Description of drawings
