[0018] Such as Figure 2~3 Shown, a spherical grid structure top cover for low-temperature liquefied gas and low-temperature natural gas storage tanks, the top cover is installed on the top of the cylindrical storage tank, including a side ring beam 1, a reticulated shell connected to the side ring beam 2 and the skin installed on the reticulated shell. The reticulated shell 2 is a spherical two-way warp grid structure, which is welded by two-way warp arc mesh rods with through-type rigid joints, and each warp arc mesh rod The radius of curvature is the same spherical radius, which can be adapted to bear the uneven load and concentrated load of more than 100 tons on the top surface under the low temperature condition of -46~-164℃. A piece of A can be intercepted in the equator or temperate zone on the spherical surface of the two-way warp ball as the mesh shell of the spherical mesh structure of the present invention, such as figure 2 Shown.
[0019] The mesh poles are made of ...
