Abstract
A Phi 60m steel bidirectional meridian latticed shell vault used in severe districts relates to an oil tank vault, and aims to solve the problem that the conventional oil tank large-diameter vault is not suitable for districts with heavier snow pressure because a certain amount of pillars are needed to be support on the tank bottom. The vault adopts the structure that arcs are formed in the length direction of upper net booms; a plurality of lower net booms are vertically arranged blow the upper net booms; the upper net booms are in contact with the short edges of the lower net booms; the top end of a top ring wallboard is connected with an edge tapered board; the inside wall of the top ring wallboard is connected with an edge node connecting part; the quantities of the upper net booms and the lower net booms are 48; a plurality of upper net booms are continuously arranged side by side; the curved surface formed by the short edges of the upper net booms are spherical, and the radius of the sphere is 51 m; and the specifications of the upper net booms and the lower net booms are 180 mm * 110 mm * 12 mm. As the short edges of the 48 upper net booms which are continuously arranged side by side form a sphere, the capability of resisting nonuniform load of the vault is stronger than that of other forms of vaults, and the stable safety degree can reach 2.2457. The vault is suitable for districts with larger snow pressure.
Description
Technical field
The utility model relates to a kind of oil tank vault.
Background technology
The structure of existing oil tank vault mainly contains the self-support type vertex of a cone, the brace type vertex of a cone, self-support type vault and several structures of spherical shell vault with ribbing, and wherein the self-support type vertex of a cone and self-support type vault are applicable to the storage tank of volume less than 1,000 sides; Spherical shell vault with ribbing is applicable to that volume is less than 10,000 sides, the diameter storage tank less than 40m; Though the brace type vertex of a cone can be made than major diameter, because the shore supports that the brace type vertex of a cone need be provided with some at the bottom of the jar, therefore is not suitable for internal floating roof tank.Generally adopt the major diameter internal floating roof tank in high and cold crushing by snow larger area, but the at present domestic high and cold crushing by snow larger area diameter that is used for is that precedent is not still built on the large-scale net shell top of 60m.
The utility model content
The purpose of this utility model is for solving shore supports that existing oil tank major diameter vault need be provided with some at the bottom of the jar, be not suitable for the problem of crushing by snow larger area, the two-way net radial shell of a kind of extremely frigid zones Φ 60m steel vault being provided.
The utility model comprises many online bars, many off line bars, a plurality of mid-side node connectors, the limit cone-plate, collar wallboard and covering, online bar and off line bar are unequal angle, the online bar is provided with arc along its length, many online bars are provided with side by side continuously, many off line bars be vertically installed in the online bar below, off line bar is Shuangzi noon line structure with the online bar, the online bar contacts with off line bar minor face, covering is identical with online bar radian, the both sides top margin of every online bar is connected with covering by the limit cone-plate respectively, be connected with a mid-side node connector below the minor face of every online bar both sides, the top of collar wallboard is connected with the limit cone-plate, the inside wall of collar wallboard is connected with the mid-side node connector, the quantity of online bar and off line bar is 48, and many online bars are provided with side by side continuously, and the curved surface that the minor face of many online bars forms is spherical, its radius of a ball is 51m, the long hem width degree * minor face width * limit of online bar and off line bar is thick=and 180mm * 110mm * 12mm.
The utility model has the advantages that: one, because 48 online bars are to be provided with continuously side by side, its minor face forms sphere, therefore anti-uneven load can be eager to excel by the other forms of vault of force rate, and its stability safety (that is: critical load parameter) reaches 2.2457, is applicable to the crushing by snow larger area.Two, the thickness of each part in the utility model all is not less than 10mm, so resistance to corrosion is strong.Three, each component in the utility model all can carry out being transported to the scene after prefabricated in factory, so highly versatile, and are easy for installation.Four, the utlity model has usability preferably, maximization along with domestic and international petroleum and petrochemical industry product oil storage volumes, and the externally influence of floating storage tank of environment, the construction of major diameter vault storage tank seems also and more and more is necessary that this utility model also will have wide practical use.
