Abstract
The utility model discloses a storing tank top cover containing bidirectional meridian vaulted net case which is arranged on the top of the cylindrical storing tank and includes an edge ring beam, a net case connected on the edge ring beam and a covering arranged on the net case. The storing tank top cover containing bidirectional meridian vaulted net case is characterized in that the net case is a bidirectional meridian vaulted net case which is formed by the bidirectional meridian arc-shaped net perch intersected and welded. The curvature radius of each bidirectional meridian arc-shaped net perch is the same radius of sphere. The covering is formed by the rectangular plates with different sizes welded according to the arrangement like the Chinese Character 'ren'. Because the storing tank top cover containing bidirectional meridian vaulted net case of the utility model adopts the bidirectional meridian vaulted net case structure, the net case structure is uniformly arranged, saves the steel and has high security. The storing tank top cover containing bidirectional meridian vaulted net case is suitable to be used for the storing tank with the atmosphere pressure and is also suitable to be used for the storing tank with the low pressure.
Description
Technical field
The utility model relates to a kind of petrochemical complex warehousing and transportation facilities, particularly a kind of basin top cover that contains the vaulted net shell of two-way radial that is installed on the basin.
Background technology
In petroleum chemical industry and relevant accumulating industry, be extensive use of the vertical and cylindrical basin to store crude oil and oil gas product.Along with the crude oil in China import volume is increasing, the demand of this basin is increasing, and to large scale development.Along with the maximization of basin, more and more higher to the requirements for quality of basin top cover, the quality of basin top cover becomes the important step of the safety, economy and the ease of use that influence large storage tank.The basin top cover generally by the side ring beam, be connected the net shell on the side ring beam and the covering that is installed on the net shell constitutes, the key factor that influences basin top cover quality is a latticed shell structure.Latticed shell structure at present commonly used mainly contains ribbed shell, through broadwise net shell and network of triangle graticule mesh shell.All there is shortcoming separately in the top cover that above-mentioned three kinds of latticed shell structures are applied to large storage tank, and the major defect of ribbed shell is that steel quantity consumption is big, and degree of safety is low; Major defect through broadwise net shell is that structural arrangement is inhomogeneous; The major defect of network of triangle graticule mesh shell is that node rigidity is low.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned shortcoming that prior art exists, and a kind of basin top cover that contains the vaulted net shell of two-way radial is provided.
To achieve these goals, the utility model has adopted following technical scheme: a kind of basin top cover that contains the vaulted net shell of two-way radial, be installed in the top of cylindrical container, comprise the side ring beam, be connected the net shell on the side ring beam and be installed in covering on the net shell, described net shell is the vaulted net shell of two-way radial, be welded by two-way radial arc net bar is crossing, the radius of curvature of each two-way radial arc net bar is the same radius of a ball, and described covering is welded by " people " font row plate by the rectangular plate that varies in size.
Described radius of curvature is 0.8-1.5 a times of basin internal diameter.
Described arc net bar is processed by angle steel or i shaped steel.
Described covering is installed in the upper surface or the lower surface of net shell.
The basin top cover that contains the vaulted net shell of two-way radial of the present utility model is owing to having adopted the vaulted latticed shell structure of two-way radial, and its latticed shell structure arranges that evenly steel quantity consumption is little, the degree of safety height.The net bar is the arc net bar that is processed by angle steel or i shaped steel, can realize that good line contacts with covering, makes the top cover moulding attractive in appearance, and power transmission is good.In addition,, form firm rigidity node, improved basin top cover wind resistance effectively, resisted the ability of inhomogeneous load because two-way net bar intersection and net boom end all adopt welded structure with being connected of side ring beam and tank skin.Covering adopts " people " font row plate, both savings of labor, and material-saving is compared with melon skin shape row plate again, can save steel 6-7%.The basin top cover that contains the vaulted net shell of two-way radial of the present utility model both had been applicable to the normal pressure basin, also was applicable to low-pressure tank.
Description of drawings
Fig. 1 is the structural principle scheme drawing that the utility model contains the vaulted net shell of two-way radial in the basin top cover of the vaulted net shell of two-way radial;
Fig. 2 is the structure birds-eye view that the utility model contains the basin top cover of the vaulted net shell of two-way radial.
The specific embodiment
See also Fig. 1, Fig. 2.Fig. 1 is the structural principle scheme drawing that the utility model contains the vaulted net shell of two-way radial in the basin top cover of the vaulted net shell of two-way radial, and Fig. 2 is the structure birds-eye view that the utility model contains the basin top cover of the vaulted net shell of two-way radial.The basin top cover that the utility model contains the vaulted net shell of two-way radial is installed in the top of cylindrical container, comprises side ring beam 1, is connected the net shell 2 on the side ring beam and is installed in covering 3 on the net shell.Its net shell is the vaulted net shell of two-way radial, is intersected by two-way radial arc net bar 21 to be welded, and the radius of curvature of each two-way radial arc net bar is the same radius of a ball, and this radius of curvature generally is designed to 0.8～1.5 times of basin internal diameter.The structural principle of the vaulted net shell of two-way radial sees also Fig. 1.Arc net bar 21 is processed by angle steel or i shaped steel, and it has good line to contact with covering.Two-way net bar intersection and net boom end all adopt welded structure with being connected of side ring beam and tank skin, form firm rigidity node.Covering is welded by " people " font row plate by the rectangular plate that varies in size, and can be installed in the upper surface of net shell.Also can be installed in the lower surface of net shell.
