Abstract
The utility model discloses a hexagonal cold-bend hollow profiled bar, which is characterized in that: the profiled bar is a hollow cylinder composed of six-sided steel plates, and the cylinder is formed by cold-bending; and the section shape of the cylinder is a hexagon which is symmetrical along a certain line of symmetry, and six sides have unequal lengths. In the hexagonal cold-bend hollow profiled bar, the bearing capacity of a steel structure, a crane boom and equipment can be improved, and is more than 15 percent higher than that of an ordinary component, and the weights of the steel structure, the crane boom, the equipment and the like are reduced by more than 5 percent.
Description
Technical field:
The utility model relates to a kind of steel, especially relates to a kind of high-quality high-strength weathering type clod wash hollow section.
Background technique:
What supply on the market is hot rolling or clod wash shape, two limit shapes, triangle, quadrilateral steel profile on one side mostly.The occasion that shaped steel is had specific (special) requirements along with construction such as energy-saving and environmental protection, building, head tower, Steel Mast, bridge and steel structure, lifting, device fabrications, can not satisfy the demand in aspects such as common shaped steel bearing capacity, environmental protection, the high-quality high-strength weathering steel is by adding a small amount of alloying element, making it have the High Strength Low Alloy Steel of good corrosion resistance energy in structure, natural atmosphere.In addition, weathering steel also has good mechanics, welding usability.Restriction owing to being subjected to its shaped steel moulding process causes the kind of Lightweight Steel Shape more single, and is present, still the Hexagon hollow section that does not form by cold bending process.
Summary of the invention:
The purpose of this utility model is: a kind of rational in infrastructure, Hexagon clod wash hollow section that bearing capacity is big is provided.
The technical solution of the utility model is: the inside of being made up of the steel plate of six faces is hollow cylinder, and described cylinder forms by clod wash, and the sectional shape of cylinder is the Hexagon along a certain symmetrical line symmetry, and six limits are not isometric.
The beneficial effects of the utility model are: the hexagon shaped steel that is formed by clod wash by high-quality high-strength weathering shaped steel plate adapts to the various damage capabilities under the nature, tension, the twisting strength of shaped steel have been increased, improve the bearing capacity of its structure, do not adopt any preservative treatment, high-efficiency environment friendly.The utility model can improve shaped steel greatly at steel structure, equipment, the isostructural bearing capacity of shear leg, bearing capacity is higher than more than 15% of general steel plate arm, simultaneously can suitably reduce steel plate specification such as steel structure, device fabrication, arm of derrick, reduce more than 5% of weight such as steel structure, arm of derrick, device fabrication, applicable to construction, manufacturing industry such as shaft tower lifting, mobile lifting, flexible lifting, bridge, steel structure, also applicable to occasions such as steel structure body miscellaneous parts.
Description of drawings:
Fig. 1 is the structural representation of a kind of Hexagon clod wash of the utility model hollow section;
Fig. 2 is an application example one of the present utility model;
