Abstract
The invention relates to a large-sized stress coating net-shell vertical-typed storage tank, and belongs to the vertical-typed oil storage tank, which comprises a soleplate and a wall panel, and also comprises a net shell, wherein, the net shell is arranged at the external layer, and the soleplate and the wall panel are arranged at the internal layer; the net shell is of a space linkwork structure that is formed by a rod piece and a node, and adopts the cone unit or the intersecting truss system; the net shell and the under-plate are welded with the wall panel through a node. The soleplate, the tank wall coat and the net shell are combined to work, and the characteristics of the net shell such as good tensile performance and good anti-bending strength are utilized to effectively reduce the thickness of the under-plate and the plate of the tank wall, thereby favoring the reduction of the cost of the storage tank, and the vertical tank is suitable to be made into a large-sized storage tank with the storage capacity being more than 150 thousand cubic meters or with the diameter being more than 100 meters.
Description
One, technical field:
What the present invention relates to is vertical petrol storage tank, and what be specifically related to is large-scale stress outer panel skin net-shell vertical storage tank.
Two, background technology:
Vertical storage tank is towards large scale development at present.The base plate of traditional vertical storage tank and wallboard generally adopt steel plate to make.This class storage tank relatively be fit to be built middle-size and small-size storage tank, has advantages such as design and fabrication is easy.For reserves greater than 150,000 sides or diameter greater than the large-scale storage tank more than 100 meters, traditional vertical storage tank structure exposes a lot of shortcomings: the one, integrally-built rigidity variation.The direct result that the rigidity variation causes is exactly the wind resistance variation, be easy to construct or the unstable phenomenon of slack tank operating mode, also can cause large-scale storage tank natural vibration period and the coupling of liquid sloshing cycle under the earthquake, further quicken the destruction of large-scale storage tank structure and floating roof structure.The 2nd, sheet metal thickness transfinites, to material and construction technical requirement strictness.For reserves greater than 150,000 sides or diameter greater than the large-scale storage tank more than 100 meters, the steel plate thickness of wallboard root is general above 45 millimeters.Similar for the material requirements of heavy wall plate both at home and abroad, all require to satisfy the performance testing of z direction, prevent the lamellar tear phenomenon.Homemade heavy wall plate generally is difficult to satisfy this technical requirements, if adopt the import steel, will cause the large-scale storage tank cost to increase substantially.In addition, the welding requirements butt weld of heavy wall plate need to guarantee welding quality and to reduce welding deformation, cause the production cycle lengthening in strict accordance with two-sided, multiple tracks subregion welding.
Three, summary of the invention:
The purpose of this invention is to provide a kind of large-scale stress outer panel skin net-shell vertical storage tank, be used to solve the problem that adopts general steel plate can not build large-scale storage tank.
The technical solution adopted for the present invention to solve the technical problems is: a kind of large-scale stress outer panel skin net-shell vertical storage tank comprises base plate and wallboard, also comprises the net shell, and the net shell is at skin, and base plate and wallboard are at internal layer; The net shell is the space bar structure that is formed by connecting by rod member and node, can adopt conical element or intersect the truss system; Net shell and base plate and wallboard are all by the node weld together.
The rod member of net shell is other section bars such as steel pipe or angle steel, channel-section steel, I-beam section in the such scheme, the peripheral node of net shell adopts other forms such as welding hollowing ball or steel plate node, with base plate and wallboard bonded assembly node be semisphere node or global type node and steel plate node.
The conical element of net shell is pyrometric cone or quadrangular pyramid or hexagonal awl in the such scheme, the truss system of intersecting can adopt two to or three-way type.
In the such scheme, the steel plate wallboard can equate that with the height of outer field net shell this moment, the primary wind girder of steel plate wallboard was the three-layer network hull shape formula of local thickening, also can adopt single Pin space truss to reinforce.The height of steel plate wallboard and outer field net shell can not wait yet, and as if the height less than the steel plate wallboard, this moment, the primary wind girder of steel plate wallboard can adopt single Pin space truss form, so further cost-cutting.
The zone of reasonableness that further is the thickness of net shell in the such scheme and diameter ratio is between 1/50-1/40, to guarantee integrally-built resistance to compression, anti-bending strength.
Beneficial effect:
(1) can avoid sheet metal thickness to transfinite
Because need to consider that base plate and tank skin epidermis and net shell combine co-operation in the design, the present invention can make full use of the tension of net shell, the characteristics that anti-bending strength is good, reduces the sheet metal thickness of base plate and tank skin effectively, is beneficial to the reduction cost.If with steel plate base plate localized raised, also will be easy to reduce the stress concentration phenomenon at lower node place at the lower node place, reach the purpose of further raising stock utilization, speed of application and construction quality.
(2) integral structure rigidity has controllability
The tension of net shell, bending stiffness are relevant with version, the thickness of net shell, the size of mesh opening of net shell.After the version of net shell was selected, the present invention can reach the purpose of controlling large-scale storage tank integral structure rigidity by thickness and the size of mesh opening that changes the net shell.
(3) good looking appearance
The present invention has outward appearance uniqueness, grace, the advantage of good visual effect.
(4) easy construction, construction speed are fast
The construction of this stress outer panel skin net-shell vertical oil tank can be adopted modular construction, and installation rate is fast.Can build the net shell earlier during construction, the net shell adopts modular construction method.Can be used as the support that storage tank bottom plate and wallboard are built after the net shell builds up, be beneficial to the splicing and the welding of follow-up base plate and wallboard.
