Abstract
The utility model relates to the technical field of steel pipes, in particular to a high-strength steel pipe. The steel pipe is an I-type steel pipe of which the two ends are thick and the middle part is thin; a spiral reinforced rib is arranged in the pipe body of the middle part of the steel pipe. According to the utility model, the steel pipe is manufactured into the I-type steel pipe of which the two ends are thick and the middle part is thin, and the spiral reinforced rib is arranged in the pipe body of the middle part of the steel pipe, so that the using requirements on the steel pipe used in a large-span structure can be met, and via the characteristics of shearing force and bending moment of the steel pipe in stress, the material is saved, and strength and rigidity requirements of the steel pipe are met at the same time.
Description
Technical field
The utility model relates to the technical field of steel pipe, especially a kind of high tensile steel tube.
Background technology
Steel pipe is widely used in industrial production, particularly in the building of electric power, metallurgy, chemical industry, machinery and lightweight steel construction, but the steel pipe that is used at present in longspan structure is all straight tube or the rectangular tube that adopts, study according to the mechanics of materials opposing load produces on rod member effect analysis, not only waste of material is very large to utilize straight tube or rectangular tube, and own wt is also large, namely wastes material, can not meet intensity and rigidity when stressed.
The utility model content
In order to overcome the deficiency of existing technology, the utility model provides a kind of high tensile steel tube.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of high tensile steel tube, steel pipe be shaped as two thick in the middle of thin " work " font steel pipe, be provided with reinforcing rib in the body of the mid portion of described steel pipe.
, according to another embodiment of the present utility model, further comprise the helical form that is shaped as of described reinforcing rib.
The beneficial effects of the utility model are, steel pipe is made thick middle thin " work " font steel pipe in two, and be provided with spiral helicine reinforcing rib in the body of mid portion, can meet the instructions for use that is used in longspan structure, the characteristics of shearing and moment of flexure when stressed according to steel pipe, namely saved material and also met the strength and stiffness of steel pipe simultaneously.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
1. steel pipes, 2. reinforcing rib in figure.
The specific embodiment
Structural representation of the present utility model as Fig. 1, a kind of high tensile steel tube, steel pipe 1 be shaped as two thick in the middle of thin " work " font steel pipe, be provided with reinforcing rib 2 in the body of the mid portion of steel pipe 1, reinforcing rib 2 be shaped as helical form.
The utility model steel pipe 1 is made thick middle thin " work " font steel pipe in two, and be provided with spiral helicine reinforcing rib 2 in the body of mid portion, can meet the instructions for use that is used in longspan structure, the characteristics of shearing and moment of flexure when stressed according to steel pipe, namely saved material and also met the strength and stiffness of steel pipe simultaneously.
