Abstract
The utility model relates to a spherical tank pillar is connected with double -deck U -shaped layer board structure with spherical shell, its characterized in that: comprise pillar, equatorial plate, inlayer U -shaped layer board and outer U -shaped layer board, double -deck nested by outer U -shaped layer board and inlayer U -shaped layer board, outer U -shaped layer board and inlayer U -shaped layer board set up between pillar and equatorial plate, and the pillar adopts double -deck connection structure with the equatorial plate. The utility model discloses the spherical tank is with double -deck U -shaped layer board structure, has greatly improved spherical tank pillar a point local stress concentration's the condition, has improved the security that the spherical tank used greatly.
Description
Technical field
The utility model belongs to a kind of pillar for spherical storage tank and spherical shell connected support structure, relates to the linkage structure of a kind of cylindrical shape pillar and spherical coverboard, and particularly a kind of spherical tank support column is connected with spherical shell and uses Double U support board structure.
Background technique
Spherical storage tank is widely used in the fields such as petrochemical industry, metallurgy, nuclear power, Aeronautics and Astronautics, rock gas, is widely used in stored-gas or liquefied petroleum gas (LPG).At present, domestic in the prior art for spherical tank pillar be one of most important load-bearing component of spherical tank, the Security of pillar and spherical shell linkage structure plays vital effect to spherical tank safe operation.Even more important to the heavier medium spherical tank of large-scale splendid attire liquid state by it, because bottom the larger pillar joint of spherical tank deadweight, a point occurs that the situation of stress raisers be more serious, some spherical tanks often because of the design of pillar and spherical tank linkage structure unreasonable cause this place's stress operate and hydraulic pressure test operating mode time calculate and be difficult to pass through.
Summary of the invention
The utility model overcomes the defect of above-mentioned existence, and object is rationally connected with posts bottom for solving spherical storage tank, provides a kind of spherical tank support column to be connected with spherical shell and use Double U support board structure.
The utility model spherical tank support column is connected with Double U support board structure content Description with spherical shell:
The utility model spherical tank support column is connected with spherical shell uses Double U support board structure, it is characterized in that: be made up of pillar, equatorial plate, internal layer U-shaped supporting plate and outer U-shaped supporting plate, by outer U-shaped supporting plate and internal layer U-shaped supporting plate double-layer nested, outer U-shaped supporting plate and internal layer U-shaped supporting plate are arranged between pillar and equatorial plate, and pillar and equatorial plate adopt double-deck linkage structure.
The utility model spherical tank support column is connected with spherical shell uses Double U support board structure, significantly improves the situation of spherical tank support column a point stress raisers, substantially increases the Security that spherical tank uses.
Accompanying drawing explanation
Fig. 1 is that spherical tank support column is connected with Double U support board structure schematic diagram with spherical shell;
In figure: 1 be pillar, 2 are equatorial plates, 3 are internal layer U-shaped supporting plates, 4 is outer U-shaped supporting plates.
Embodiment
The utility model spherical tank support column is connected with spherical shell and is achieved in that with Double U support board structure and illustrates below in conjunction with accompanying drawing.
See Fig. 1, the utility model spherical tank support column is connected with spherical shell uses Double U support board structure, by: pillar 1, equatorial plate 2, internal layer U-shaped supporting plate 3 and outer U-shaped supporting plate 4 form, by outer U-shaped supporting plate 4 and internal layer U-shaped supporting plate 3 double-layer nested, outer U-shaped supporting plate 4 and internal layer U-shaped supporting plate 3 are arranged between pillar 1 and equatorial plate 2, and pillar 1 and equatorial plate 2 adopt double-deck linkage structure.
Add and first pillar 1 and equatorial plate 2 welding are fixed together man-hour, again internal layer U-shaped supporting plate 3 and pillar 1 and equatorial plate 2 welding are fixed together, then outer U-shaped supporting plate 4 are formed together with pillar 1 and equatorial plate 2 welding the double-deck form connected.
The utility model spherical tank support column is connected with spherical shell uses Double U support board structure, pillar 1 can adopt with Spherical Tank Shell Plates intensity and the suitable seamless steel pipe of low-temperature impact toughness or to adopt and Spherical Tank Shell Plates rolls with the steel plate of material, equatorial plate 2 adopts the manufacture of GB713, GB3531, GB19189, GB24511 equal pressure container steel plate special, and internal layer U-shaped supporting plate 3 and outer U-shaped supporting plate 4 adopt and make with the steel plate of Spherical Tank Shell Plates with material.First pillar 1 and equatorial plate 2 attachment portion are cut by Spherical Tank Shell Plates curvature, cutting after group to and adopt shielded metal arc welding to weld, weld and weld seam need have been carried out 100%MT detection by NB/T47013.4-2015 non-destructive inspection standard, detect qualified continuous by internal layer supporting plate by Spherical Tank Shell Plates curvature and the cutting of supporting tube curvature and with pillar and equatorial plate group to and adopt shielded metal arc welding to weld, weld seam is carried out 100%MT detection by NB/T47013.4-2015 non-destructive inspection standard by postwelding, detect qualified continuous by outer supporting plate by Spherical Tank Shell Plates curvature and the cutting of supporting tube curvature and with pillar and equatorial plate group to and adopt manual electric arc welding to weld, weld seam is carried out 100%MT by NB/T47013.4-2015 non-destructive inspection standard and detects to qualified by postwelding.In welding process, 1 ~ 4 need adopt complete penetraction and fusion in welding structure.
The utility model " Double U support board structure " adopts double-layer nested formula U-shaped supporting plate form, the join strength of pillar and spherical shell is improve compared with original individual layer " adding U-shaped support board structure pattern ", improve the stress distribution of pillar and spherical shell connection part, reduce spherical tank is connected minimum point place a point stress index with pillar, in same parameter situation, a point stress can decline more than 20%, improvement and reducing effect are served to the most centrostigma a point stress of spherical tank spherical shell stress, thus situation about avoiding owing to improving Spherical Tank Shell Plates thickness for reducing a point stress, Construction of spherical tank economic indicator is again reduced while raising spherical tank runs safety in utilization, significantly improve the situation of spherical tank support column a point stress raisers, substantially increase the Security that spherical tank uses.
