Embodiment Construction

[0028] see figure 1 , figure 2 , the structure of the local double-layer spherical reticulated shell storage tank vault in the present embodiment is: the middle part of the storage tank vault is set as a Kaiwitt type single-layer spherical reticulated shell 31, which is formed by connecting rods and nodes; the storage tank vault The outer periphery is a double-layer reticulated shell 32 with an outer net and an inner net formed by connecting the rods and nodes.

[0029] In the specific implementation, the corresponding structure is set as:

[0030] Such as image 3 with Figure 4 As shown, the outer mesh in the double-layer reticulated shell in this embodiment adopts rib ring mesh, and the rib ring mesh and the inner layer mesh form a quadrangular pyramid system, and the thickness of the double-layer reticulated shell is 2-3 meters. The double-layer reticulated shell structure is set as follows: two adjacent rib ring network ring rods 1 and two adjacent rib ring network r...

Abstract

The invention discloses a partial double-layer spherical reticulated shell storage tank vault structure. The partial double-layer spherical reticulated shell storage tank vault structure is characterized in that part of the periphery is a double-layer reticulated shell, the middle is a single-layer reticulated shell, and stressed-skin diaphragms are laid on the top of the double-layer reticulated shell and the top of the single-layer reticulated shell to be used as a storage tank vault. The single-layer reticulated shell in the middle of the reticulated shell is a Kiewitt reticulated shell, the outer layer of the double-layer reticulated shell in the part of the periphery is rib ring reticulated shell, and the rib ring reticulated shell and the inner layer are connected to form a quadrangular pyramid system. The reticulated shell is composed of chord members, web members and panel joints. Member pieces are steel tubes or profile steel, the panel joints are board panel joints or ball panel joints, and the member pieces are connected through the panel joints in a welding mode or through bolts in an assembling mode to form the reticulated shell. The inner layer and the outer layer of the whole reticulated shell are supported on supports of a tank wall or a ring beam to support the storage tank vault. The partial double-layer spherical reticulated shell storage tank vault structure has the advantages of being concise in structure, easy to construct, capable of being superior to the single-layer reticulated shell in carrying capacity, and applied to occasions with storage tanks of larger diameters and long-span vaults.

Description

technical field [0001] The invention relates to a storage tank vault space support structure, in particular to a storage tank vault structure which is especially applied to large storage tanks in the field of petrochemical industry. Background technique [0002] With the rapid development of the petroleum and chemical industry, in order to save investment, the volume of storage tanks continues to expand, and the development of larger-span vault support structures will break through the bottleneck of storage tank expansion. [0003] In the prior art, the single-layer reticulated shell is widely used, and its structure is simple, with few rods and joints, but its bearing capacity is low, and the actual stress of the material is only about 1 / 6-1 / 10 of the allowable stress. Low; the existing double-layer reticulated shell structure, its rods mainly bear the axial force, the secondary bending moment is small, the structural bearing capacity is high, the overall mechanical perform...
