Embodiment 1

[0028] Combine figure 1 , figure 2 As shown, the large-scale stress-skinned net shell vertical storage tank of this embodiment is a cylindrical open tank, with a steel plate bottom plate 1 and a steel plate wall 2 on the inner layer, and a layer of mesh outside each of the steel plate bottom plate 1 and the steel plate wall 2 Shell 3, reticulated shell 3 and steel siding 2 have the same height, which is a steel siding structure that all adopts reticulated shell 3. The reticulated shell 3 has a uniform cross-section from bottom to top. Of course, variable cross-sections can also be used, that is, lower thickness and upper thickness. Thin; the node 5 connecting the reticulated shell 3 with the bottom plate 1 and the wall plate 2 is a hemispherical node, the node can also be designed as a global node, and the reticulated shell 3 and the bottom plate 1 and the wall plate 2 are all welded together by hemispherical nodes. The reticulated shell 3 is a spatial rod system structure form...

Embodiment 2

[0032] Combine image 3 , Figure 4 As shown, the structure of this embodiment is different from Example 1 in that the wall structure of the evacuated quadrangular pyramid reticulated shell is adopted. The figure shows a single-cell evacuated form, 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 panel 2 is reinforced by a single-thrust three-dimensional truss. The other structure is the same as the first embodiment.

Embodiment 3

[0034] Combine Figure 5 , Image 6 As shown, this embodiment adopts a part of the wall structure of the reticulated shell. The height of the reticulated shell 3 outside the steel siding 2 is smaller than the height of the steel siding 2. At this time, the size of the reticulated shell 3 can be determined according to the design and construction requirements. Cover height; there is a layer of net shell 3 outside the entire steel plate bottom plate 1. The reticulated shell 3 adopts the cone unit as a quadrangular pyramid, which can be prefabricated in the factory and installed with steel plate on site; the reticulated shell 3 adopts a quadrangular pyramid type, the ratio of the thickness to the diameter of the reticulated shell 3 is 1 / 40. At this time, the wind-resistant ring of the upper steel plate siding 2 can be in the form of a single 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-skinned net shell vertical storage tank. 2. Background technology: [0002] At present, vertical storage tanks are moving towards large-scale development. The bottom and wall panels 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-sized storage tanks, and has the advantages of simple design and production. For large storage tanks with a storage capacity of more than 150,000 square meters or a diameter of more than 100 meters, the traditional vertical storage tank structure exposes many shortcomings: First, the rigidity of the overall structure becomes worse. The direct consequence of the deterioration of rigidity is the deterioration of wind resistance, which is prone to instability in construction or empty tank conditions. It will also cause the coupling of t...
