The utility model adopts following technological scheme:
A kind of assembly type light-high-strength metal pipe; Comprise at least two ring type structure wall, Stamping Steel Ribbon and bolts that structure is identical; The both sides of each ring type structure wall are respectively equipped with outer folding edge; Outer folding use through hole, each ring type structure wall formation circular pipe that connects along being provided with assembling, and two outer foldings of each side that connects are provided with Stamping Steel Ribbon along between the interface; Stamping Steel Ribbon is provided with and assembles with the corresponding through hole of through hole, and bolt links through the through hole ring type structure wall that each structure is identical on outer folding edge, the Stamping Steel Ribbon.
Wherein, above-mentioned ring type structure wall comprises the outer wall on the outer folding of band edge and the inwall two-part on the outer folding of band edge, and inwall is provided with the enhancing rib; Perhaps, above-mentioned ring type structure wall is an overall structure, strengthens rib and is welded on the outside that outer outside, the outer wall of rolling over the inwall on edge of band is welded on the enhancing rib.
Wherein, above-mentioned enhancing rib and the axis of tubing forms an angle and equidistantly arrange, smaller or equal to 90 degree, spacing is greater than zero more than or equal to zero degree for angle.
Wherein, the cross section of above-mentioned enhancing rib is solid or hollow square, triangle, circle, semicircle, ellipse or polygonal.
Wherein, the internal surface of the outer surface of the outer wall of above-mentioned ring type structure wall, inwall is equipped with the corrosion-inhibiting coating of flame-retardant and anti-static.
The utility model compared with prior art has following beneficial effect:
1, this tubing linear mass is light, has only about the 40%-60% of common steel tube.
2, have good fire prevention, high temperature resistant, anti-static electricity property.
3, this tubing can be realized plant produced, builder's yard assembling, and processing cost is low.
4, this tubing can reduce cost of transportation greatly, saves more than 400% with respect to conventional steel.
