Description
Technical field
The utility model is related to a kind of high intensity polygon steel pipes with straight, belongs to steel construction piece technical field.
Background technology
The development of steel pipe's production technology starts from the manufacturing rise of bicycle, the exploitation of 19th century younger oil, twice
During world war after the manufacture of naval vessel, boiler, aircraft, World War II apparatus of thermo-electric power boiler manufacture, the hair of chemical industry
Exhibition and the drilling of petroleum gas and transport etc., all effectively promote hair of the Steel Tube Industries in kind, yield and quality
Exhibition.
Steel pipe is applied not only to trandfer fluid and powdery solid, exchanges heat energy, manufacture machine components and container, and it is still a kind of
Economic steel.Building structure rack, pillar and machinery mount are manufactured with steel pipe, weight can be mitigated, metal 20~40% is saved,
And batch production mechanized construction can be realized.Highway bridge is manufactured with steel pipe can not only save steel, simplify construction, and can be big
The big area for reducing stopping off, investment reduction and maintenance cost.
The steel grade of tube product is extremely various with description, its performance requirement be also it is various, it is all these should
It is distinguish between with user's requirement or the change of condition of work.The cross sectional shape of usual steel pipe is circle, and round tube can be with defeated
Send more fluids.In addition, ring cross-section is when bearing internal or external radial pressure, stress is more uniform.
But pipe causes it to be not used to some particular surroundings because shape is limited, because the moment of inertia and the section of pipe
Modulus is smaller, and its bending resistance and anti-twisting property are poor, low intensity.
Utility model content
Technical problem to be solved in the utility model is straight for a kind of high intensity polygon of above-mentioned prior art offer
Steel pipe is stitched, its intensity is high, and bending resistance and anti-twisting property are stronger, can effectively prevent steel pipe stress deformation in use.
The technical scheme in the invention for solving the above technical problem is：A kind of high intensity polygon steel pipes with straight, it
Including polygon body, joint is provided with wherein one side of the polygon body, the joint is set by submerged-arc welding mode
Outside weld and inside weld are equipped with, the polygon tubular body is provided centrally with pipe, the circular tube external wall and polygon body
Each angle between be provided with supporting plate, be provided with reinforcing plate on the inside of the inside weld.
The ratio between depth of the outside weld and inside weld is 1:3.
The supporting plate is identical with the wall thickness of pipe.
The cross sectional shape of the polygon body is hexagon.
The ratio between the wall thickness of the polygon body and the wall thickness of pipe are 1.5:1.
Compared with prior art, the utility model has the advantage of：
A kind of high intensity polygon steel pipes with straight of the utility model, its intensity is high, and bending resistance and anti-twisting property are stronger, Neng Gouyou
Effect prevents steel pipe stress deformation in use；The ratio between outside weld depth and the depth of inside weld are 1:3, therefore substantially reduce
The size of outer side weld so that pipe fitting good appearance；Reinforcing plate is provided with the inside of inside weld, it is possible to increase pipe fitting commissure
Intensity.

As shown in figure 1, a kind of high intensity polygon steel pipes with straight in the present embodiment, it includes polygon body 1, described
Joint 2 is provided with wherein one side of polygon body 1, the joint 2 is provided with outside weld 3 and interior weldering by submerged-arc welding mode
Seam 4, the inside center of polygon body 1 is provided between pipe 5, each angle of the outer wall of pipe 5 and polygon body 1
Supporting plate 6 is provided with, the inner side of inside weld 4 is provided with reinforcing plate 7；
The ratio between depth of the outside weld 3 and inside weld 4 is 1:3；
The supporting plate 6 is identical with the wall thickness of pipe 5；
The cross sectional shape of the polygon body 1 is hexagon；
The ratio between the wall thickness of the polygon body 1 and the wall thickness of pipe 5 are 1.5:1.
In addition to the implementation, the utility model also includes other embodiment, all use equivalents or equivalent
The technical scheme of substitute mode formation, all should fall within the utility model scope of the claims.
