Embodiment 1

[0028] to combine figure 1 , figure 2 As shown, the large stress-skin reticulated shell vertical storage tank of this embodiment is a cylindrical open tank, the steel plate bottom plate 1 and the steel plate wall plate 2 are the inner layer, and the steel plate bottom plate 1 and the steel plate wall plate 2 have a layer of netting respectively. The shell 3, reticulated shell 3 and the steel plate wall plate 2 are of the same height, which is the steel plate wall plate structure of the reticulated shell 3. The reticulated shell 3 is of equal cross-section from bottom to top. Of course, variable cross-section can also be used, that is, the lower thickness and upper top Thin; the node 5 connecting the reticulated shell 3 to the bottom plate 1 and the wall plate 2 is a hemispherical node, which can also be designed as a spherical node, and the reticulated shell 3, the bottom plate 1 and the wall plate 2 are all welded together through a hemispherical node. The reticulated shell...

Embodiment 2

[0032] to combine image 3 , Figure 4 As shown, the structure of this embodiment differs from that of Example 1 in that the wall plate structure of the evacuated quadrangular pyramid reticulated shell is adopted. The single-cell evacuated form is shown in the figure, and other evacuated forms can also be used as required; the thickness of the reticulated shell 3 The ratio to the diameter is 1 / 45. At this time, the wind-resistant ring of the upper steel plate wall plate 2 is reinforced by a single three-dimensional truss. Other structures are the same as in Embodiment 1.

Embodiment 3

[0034] to combine Figure 5 , Figure 6 As shown, the present embodiment is a panel structure partially adopting a reticulated shell, and the height of the reticulated shell 3 outside the steel plate 2 is smaller than the height of the steel plate 2. At this time, the height of the reticulated shell 3 can be determined according to the design and construction requirements. Covering height; there is a layer of reticulated shell 3 outside the entire steel plate bottom plate 1. The reticulated shell 3 adopts pyramidal units as quadrangular pyramids. These units can be prefabricated in the factory and installed on site with steel plates; At this moment, the wind-resistant ring of the upper steel plate wall plate 2 can adopt the form of a single three-dimensional truss.

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

1. Technical field: [0001] The invention relates to a vertical oil storage tank, in particular to a large stress-skin reticulated vertical storage tank. 2. Background technology: [0002] At present, vertical storage tanks are developing toward large scale. The bottom plate and wall plate of traditional vertical storage tanks are generally made of steel plates. This type of storage tank is more suitable for the construction of small and medium storage tanks, and has the advantages of simple design and manufacture. For large storage tanks with a storage capacity of more than 150,000 m3 or a diameter of more than 100 meters, the traditional vertical storage tank structure has exposed many shortcomings: First, the rigidity of the overall structure has deteriorated. The direct consequence of poor stiffness is poor wind resistance, which is prone to instability during construction or empty tank conditions. It will also lead to coupling between the natural vibration period of la...
