Problems solved by technology

When this kind of reticulated shell is used for large-diameter oil tanks, due to the rapid increase in the structure's self-weight, as the diameter increases, the structure's ability to resist earthquakes decreases, and often does not meet the requirements of the code.

Embodiment

[0025] A large-span vertical cylindrical oil tank of 100,000 cubic meters or more, including a cylindrical tank body composed of a tank foundation, a tank bottom plate and a tank wall. The top of the tank body is provided with a diameter of 70 meters to 95 meters The top cover of meters is composed of a combined grid structure 1 with a large span and two-way meridian and a skin 2 set on the grid structure. Such as figure 1 As shown, the combined grid structure 1 of the large-span two-way meridian is composed of two-way meridian arc-shaped net poles welded by through-type rigid joints, and the curvature radius of each meridian arc-shaped net pole is the same spherical radius. Each net pole is welded into an arc-shaped continuous net pole by I-shaped steel group, and is arranged along two radial lines, and both ends are welded together with the ring beam at the top of the tank body.

[0026] The combined grid structure is a grid structure in which the north-south and east-west ...

Abstract

The invention relates to a long-span steel vertical cylindrical oil tank of above 100 thousand cubic meters. The oil tank comprise a cylindrical tank body formed by a tank foundation, a tank bottom plate and a tank wall, a fixed top cover with the diameter of of 70 m to 95 m is arranged at the top of the tank body, and the top cover is formed by a large-span combined grid structure with bidirectional longitudes and skin on the grid structure. Compared with the prior art, the oil tank has the advantages of being good in stressing performance, convenient to construct and mount, small in material consumption, free of stand columns in the tank, low in cost and the like.

Description

technical field [0001] The invention relates to a petrochemical storage and transportation equipment, in particular to a large-span steel vertical cylindrical oil tank of 100,000 cubic meters or more. Background technique [0002] The quality of refined oil not only depends on the level of petroleum refining, but also directly related to the function of storage and transportation equipment. [0003] For example: when using an open-type external floating roof oil tank to store refined oil, rainwater and sand and dust will pollute the oil along the inner wall of the tank. If a floating roof tank with a cover is used, the fixed roof can be added to become an internal floating roof oil tank, which can not only effectively prevent environmental pollution of oil products, but also eliminate the harm of lightning strikes to the oil tank. [0004] With the development of the global economy, the demand for refined oil products is increasing, and the corresponding logistics and stora...
